DISCLOSURE               For the Period September 1, 2004 to February 28, 2005
 OF FUND EXPENSES


As a shareholder of a fund, you incur two types of costs: (1) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (2) ongoing costs,
including management fees; distribution and/or service (12b-1) fees; and other
fund expenses. The following examples are intended to help you understand your
ongoing costs (in dollars) of investing in a fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The Examples are based on an investment of $1,000 invested at the beginning of
the period and held for the entire period September 1, 2004 to February 28,
2005.

ACTUAL EXPENSES
The first section of the tables shown, "Actual Fund Return," provides
information about actual account values and actual expenses. You may use the
information in this section of the table, together with the amount you invested,
to estimate the expenses that you paid over the period. Simply divide your
account value by $1,000 (for example, an $8,600 account value divided by $1,000
= 8.6), then multiply the result by the number in the first section under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second section of the tables shown, "Hypothetical 5% Return," provides
information about hypothetical account values and hypothetical expenses based on
the Fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Fund's actual return. The hypothetical account
values and expenses may not be used to estimate the actual ending account
balance or expenses you paid for the period. You may use this information to
compare the ongoing costs of investing in the 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 table 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 the 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. The Fund's actual expenses shown in the table reflect fee waivers in
effect. The expenses shown in the table assume reinvestment of all dividends and
distributions. In each case, "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).

(1)  Effective November 1, 2004, The Fund's manager increased contractual
     expense waivers in effect for the Fund, causing the expenses paid by the

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

(2) 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 waivers and payment of fees by the
    manager, as applicable. Performance would have been lower had the expense
    limitation not been in effect.

(3) As required, effective September 1, 2001, the Fund adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies that
    require amortization of all premiums and discounts on debt securities. This
    change in accounting had no impact for the year ended August 31, 2002. Per
    share data and ratios for periods prior to September 1, 2001 have not been
    restated to reflect this change in accounting.

NOTES
  TO FINANCIAL STATEMENTS                         February 28, 2005 (Unaudited)

Voyageur Mutual Funds (the "Trust") is organized as a Delaware statutory trust
and offers six series: Delaware Tax-Free Arizona Fund, Delaware Tax-Free
California Fund, Delaware Tax-Free Idaho Fund, Delaware Minnesota High-Yield
Municipal Bond Fund, Delaware National High-Yield Municipal Bond 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
Investment Trust (the "Trust") is organized as a Massachusetts statutory trust
and offers five series: Delaware Tax-Free California Insured Fund, Delaware
Tax-Free Florida Fund, Delaware Tax-Free Florida Insured Fund, Delaware Tax-Free
Missouri Insured Fund and Delaware Tax-Free Oregon 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
footnotes pertain to Delaware Tax-Free Arizona Fund, Delaware Tax-Free Arizona
Insured Fund, Delaware Tax-Free California Fund, Delaware Tax-Free California
Insured Fund and Delaware Tax-Free Colorado Fund (each a "Fund" and,
collectively, the "Funds"). The above Trusts are open-end investment companies.
The Funds are considered non-diversified under the Investment Company Act of
1940, as amended. The Funds offer Class A, Class B, and Class C shares. Class A
shares are sold with a front-end sales charge of up to 4.50%. Class B shares are
sold with a contingent deferred sales charge that declines from 4% to zero
depending upon the period of time the shares are held. Class B shares will
automatically convert to Class A shares on a quarterly basis approximately eight
years after purchase. Class C shares are sold with a contingent deferred sales
charge of 1%, if redeemed during the first 12 months.

The investment objective of Delaware Tax-Free Arizona Fund, Delaware Tax-Free
Arizona Insured Fund, Delaware Tax-Free California Fund, Delaware Tax-Free
California Insured 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. 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.

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 Family of
Funds are allocated amongst the funds on the basis of average net assets.
Management fees and some other expenses are paid monthly. Security transactions
are recorded on the date the securities are purchased or sold (trade date).
Costs used in calculating realized gains and losses on the sale of investment
securities are those of the specific securities sold. Interest income is
recorded on the accrual basis. Discounts and premiums are amortized to interest
income over the lives of the respective securities. Each Fund declares dividends
daily from net investment income and pays such dividends monthly and declares
and pays distributions from net realized gain on investments, if any, annually.




The Funds receive earnings credits from their custodian when positive cash
balances are maintained, which are used to offset custody fees. The expense paid
under the above arrangement is included custodian fees on the Statements of
Operations with the corresponding expense offset shown as "expense paid
indirectly". The amount of this expense for the six months ended February 28,
2005 was as follows:

                                  Delaware
                              Tax-Free Arizona

                               ---------------
Earnings credits                    $110

2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS

each Fund pays Delaware Management Company (DMC), a series of Delaware

* Tax information for the period ended February 28, 2005, is an estimate and the
tax character of dividends and distributions may be redesignated at the fiscal
year end.

The components of net assets are estimated since final tax characteristics
cannot be determined until fiscal year end. As of February 28, 2005, the
estimated components of net assets on a tax basis were as follows:

For financial reporting purposes, capital accounts are adjusted to reflect the
tax character of permanent book/tax differences. For the six months ended
February 28, 2005, the Funds recorded an estimate of these differences since the
final tax characteristics cannot be determined until fiscal year end.
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.

The net assets of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free
California Fund prior to the Reorganizations were $134,516,467.57 and
$46,891,286.79, respectively.

8. LINE OF CREDIT
The Funds, along with certain other funds in the Delaware Investments Family of
Funds (the "Participants"), participate in a $183,100,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each Funds' 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, 2005, or at any time during
the period.

9. 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.

10. 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.

DISCLOSURE                 For the Period September 1, 2004 to February 28, 2005
  OF FUND EXPENSES

As a shareholder of a fund, you incur two types of costs: (1) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (2) ongoing costs,
including management fees; distribution and/or service (12b-1) fees; and other
fund expenses. The following examples are intended to help you understand your
ongoing costs (in dollars) of investing in a fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000 invested at the beginning of
the period and held for the entire period September 1, 2004 to February 28,
2005.

ACTUAL EXPENSES
The first section of the tables shown, "Actual Fund Return," provides
information about actual account values and actual expenses. You may use the
information in this section of the table, together with the amount you invested,
to estimate the expenses that you paid over the period. Simply divide your
account value by $1,000 (for example, an $8,600 account value divided by $1,000
= 8.6), then multiply the result by the number in the first section under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second section of the tables shown, "Hypothetical 5% Return," provides
information about hypothetical account values and hypothetical expenses based on
the Fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Fund's actual return. The hypothetical account
values and expenses may not be used to estimate the actual ending account
balance or expenses you paid for the period. You may use this information to
compare the ongoing costs of investing in the 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 table 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 the 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. The Funds' actual expenses shown in the table reflect fee waivers in
effect. The expenses shown in the table assume reinvestment of all dividends and
distributions. In each case, "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).

SECTOR ALLOCATION                                        As of February 28, 2005

The SEC adopted a requirement that all funds present their categories of
portfolio holdings in a table, chart, or graph format in their annual and
semiannual shareholder reports, whether or not a schedule of investments is
utilized. The following chart lists each Fund's categories of portfolio holdings
as a percentage of total net assets and is provided in compliance with such
requirement.

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

(2) 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 waivers and payment of fees by the manager, as
    applicable. Performance would have been lower had the expense limitation not
    been in effect.

(3) 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 $0.002, 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
    reflected this change in accounting.

    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

NOTES                                    DELAWARE MINNESOTA MUNICIPAL BOND FUNDS
  TO FINANCIAL STATEMENTS                February 28, 2005 (Unaudited)

Voyageur Mutual Funds (the "Trust") is organized as a Delaware statutory trust
and offers six series: Delaware Minnesota High-Yield Municipal Bond Fund,
Delaware National High-Yield Municipal Bond Fund, Delaware Tax-Free Arizona
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 shares 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 12 months.

The investment objective of Delaware Tax-Free Minnesota Fund and Delaware
Tax-Free Minnesota Insured Fund is to seek as high a level of current income
exempt from federal income tax and from the Minnesota state personal income tax,
as is consistent with preservation of capital.

The investment objective of Delaware Tax-Free Minnesota Intermediate Fund is to
seek to provide investors with preservation of capital and, secondarily, current
income exempt from federal income tax and from the Minnesota state personal
income tax, by maintaining a dollar-weighted average effective portfolio
maturity of 10 years or less.

The investment objective of Delaware Minnesota High-Yield Municipal Bond Fund is
to seek as high a level of current income exempt from federal income tax and
from the Minnesota state personal income tax, primarily through investment in
medium- and lower-grade municipal obligations.

1. SIGNIFICANT ACCOUNTING POLICIES
The following accounting policies are in accordance with U.S. generally accepted
accounting principles and are consistently followed by the Funds.

Security Valuation -- Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Short-term debt securities having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith under the direction of each Fund's Board of
Trustees. In determining whether market quotations are readily available or fair
valuation will be used, various factors will be taken into consideration, such
as market closures, or with respect to foreign securities, 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 Family of
Funds are allocated amongst the funds on the basis of average net assets.
Management fees and some other expenses are paid monthly. Security transactions
are recorded on the date the securities are purchased or sold (trade date).
Costs used in calculating realized gains and losses on the sale of investment
securities are those of the specific securities sold. Interest income is
recorded on the accrual basis. Discounts and premiums are amortized to interest
income over the lives of the respective securities. Each Fund declares dividends
daily from net investment income and pays such dividends monthly and declares
and pays distributions from net realized gain on investments, if any, annually.

The Funds receive earnings credits from their custodian when positive cash
balances are maintained, which are used to offset custody fees. The expense paid
under the above arrangement is included in custodian fees on the Statements of
Operations with the corresponding expense offset shown as "expense paid
indirectly." The amount of this expense for the six months ended February 28,
2005 were as follows:

2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH
   AFFILIATES
In accordance with the terms of its respective investment management agreement,
each Fund pays Delaware Management Company (DMC), a series of Delaware
Management Business Trust and the investment manager, an annual fee based on
each Fund's average daily net assets as follows:

                                   Delaware Tax-Free
                                      Minnesota
                                    Insured Fund

  On the first $500 million            0.500%
  On the next $500 million             0.475%
  On the next $1.5 billion             0.450%
  In excess of $2.5 billion            0.425%

DMC has contractually agreed to waive that portion, if any, of its management
fee and reimburse each Fund to the extent necessary to ensure that annual
operating expenses, exclusive of taxes, interest, brokerage commissions,
distribution fees, certain insurance costs and extraordinary expenses, do not
exceed specified percentages of average daily net assets as shown below:

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. The Funds pay
DSC a monthly fee based on average net assets subject to certain minimums for
accounting and administration services. Each Fund pays DSC a monthly fee based
on the number of shareholder accounts for dividend disbursing and transfer agent
services.

Pursuant to a distribution agreement and distribution plan, each Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.25% of the average daily net
assets of the Class A shares and 1.00% of the average daily net assets of the
Class B and C shares for all Funds. DDLP has contracted to waive distribution
and service fees through December 29, 2005 in order to prevent distribution and
service fees of Class A from exceeding 0.15% of the average daily net assets for
Delaware Tax-Free Minnesota Intermediate Fund.

At February 28, 2005, the Funds had liabilities payable to affiliates as

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, 2005 and the year ended August 31, 2004 was as
follows:

For financial reporting purposes, capital accounts are adjusted to reflect the
tax character of permanent book/tax differences. For the six months ended
February 28, 2005, each Fund recorded an estimate of these differences since the
final tax characteristics cannot be determined until fiscal year end.
Reclassifications are primarily due to tax treatment of market discounts and
premiums on certain debt instruments. Results of operations and net assets were
not affected by these reclassifications.

7. LINE OF CREDIT
The Funds, along with certain other funds in the Delaware Investments Family of
Funds (the "Participants"), participate in a $183,100,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each fund's allocation of the entire facility. The Participants may
borrow up to a maximum of one third of their net assets under the agreement. The
Funds had no amounts outstanding as of February 28, 2005 or at any time during
the period.

8. 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 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 denoted on the Statements of Net Assets.

9. CONTRACTUAL OBLIGATIONS
The Funds enter into contracts in the normal course of business that contain a
variety of indemnifications. The Funds' maximum exposure under these
arrangements is unknown. However, the Funds have not had prior claims or losses
pursuant to these contracts. Management has reviewed each Fund's existing
contracts and expects the risk of loss to be remote.
