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. 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 181/365
(to reflect the one-half year period).

(1)   As required, effective September 1, 2001, the Fund adopted the provisions
      of the AICPA Audit and Accounting Guide for Investment Companies that
      required amortization of all premiums and discounts on debt securities.
      The effect of these changes for the year ended August 31, 2002 was an
      increase in net investment income per share of $0.003, a decrease in net
      realized and unrealized gain (loss) per share of $0.003, and an increase
      in the ratio of net investment income to average net assets of 0.03%. Per
      share data and ratios for periods prior to September 1, 2001 have not been
      restated to reflect these changes in accounting.

(2)   Ratios and portfolio turnover have been annualized and total return has
      not been annualized.

(3)   Total investment return is based on the change in net asset value of a
      share during the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects a waiver and payment of
      fees by the manager, as applicable. Performance would have been lower had
      the expense limitation not been in effect.

(1)   As required, effective September 1, 2001, the Fund adopted the provisions
      of the AICPA Audit and Accounting Guide for Investment Companies that
      required amortization of all premiums and discounts on debt securities.
      The effect of these changes for the year ended August 31, 2002 was an
      increase in net investment income per share of $0.003, a decrease in net
      realized and unrealized gain (loss) per share of $0.003, and an increase
      in the ratio of net investment income to average net assets of 0.03%. Per
      share data and ratios for periods prior to September 1, 2001 have not been
      restated to reflect these changes in accounting.

(2)   Ratios and portfolio turnover have been annualized and total return has
      not been annualized.

(3)   Total investment return is based on the change in net asset value of a
      share during the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects a waiver and payment of
      fees by the manager, as applicable. Performance would have been lower had
      the expense limitation not been in effect.

      of the AICPA Audit and Accounting Guide for Investment Companies that
      required amortization of all premiums and discounts on debt securities.
      The effect of these changes for the year ended August 31, 2002 was an
      increase in net investment income per share of $0.002, a decrease in net
      realized and unrealized gain (loss) per share of $0.002, and an increase
      in the ratio of net investment income to average net assets of 0.02%. Per
      share data and ratios for periods prior to September 1, 2001 have not been
      restated to reflect these changes in accounting.

(2)   Ratios and portfolio turnover have been annualized and total return has
      not been annualized.

(3)   Total investment return is based on the change in net asset value of a
      share during the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects a waiver and payment of
      fees by the manager, as applicable. Performance would have been lower had

(1)   As required, effective September 1, 2001, the Fund adopted the provisions
      of the AICPA Audit and Accounting Guide for Investment Companies that
      required amortization of all premiums and discounts on debt securities.
      The effect of these changes for the year ended August 31, 2002 was an
      increase in net investment income per share of less than $0.001, a
      decrease in net realized and unrealized gain (loss) per share of less than
      $0.001, and an increase in the ratio of net investment income to average
      net assets of less than 0.01%. Per share data and ratios for periods prior
      to September 1, 2001 have not been restated to reflect these changes in
      accounting.

(2)   Ratios and portfolio turnover have been annualized and total return has
      not been annualized.

(3)   Total investment return is based on the change in net asset value of a
      share during the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects a waiver and payment of
      fees by the manager, as applicable. Performance would have been lower had
      the expense limitation not been in effect.

(1)   As required, effective September 1, 2001, the Fund adopted the provisions
      of the AICPA Audit and Accounting Guide for Investment Companies that
      required amortization of all premiums and discounts on debt securities.
      The effect of these changes for the year ended August 31, 2002 was an
      increase in net investment income per share of $0.001, a decrease in net
      realized and unrealized gain (loss) per share of $0.001, and an increase
      in the ratio of net investment income to average net assets of 0.01%. Per
      share data for periods prior to September 1, 2001 have not been restated
      to reflect these changes in accounting.

(2)   Ratios and portfolio turnover have been annualized and total return has
      not been annualized.

(3)   Total investment return is based on the change in net asset value of a
      share during the period and assumes reinvestment of dividends and
      distributions at net asset value and does not reflect the impact of a
      sales charge. Total investment return reflects a waiver and payment of
      fees by the manager. Performance would have been lower had the expense
      limitation not been in effect.

   TO FINANCIAL STATEMENTS

Voyageur Mutual Funds (the "Trust") is organized as a Delaware statutory trust
and offers five series: Delaware Minnesota High-Yield Municipal Bond Fund,
Delaware National High-Yield Municipal Bond Fund, Delaware Tax-Free California
Fund, Delaware Tax-Free Idaho Fund and Delaware Tax-Free New York Fund. 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 statutory 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 B shares will automatically
convert to Class A on a quarterly basis approximately eight years after purchase
for Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund
and Delaware Minnesota High-Yield Municipal Bond Fund and approximately five
years after purchase for Delaware Tax-Free Minnesota Intermediate Fund. 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."

Delaware Service Company, Inc. (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. DDLP has contracted to waive distribution fees through
December 31, 2006 in order to prevent distribution and service fees of Class A
shares from exceeding 0.15% of average daily net assets for Delaware Tax-Free
Minnesota Intermediate Fund.

      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

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 year ended August 31, 2005 was as follows:

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.

   TO FINANCIAL STATEMENTS (CONTINUED)

6. 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.
