PLEASE DESCRIBE THE OVERALL MARKET CONDITIONS DURING
THE FISCAL YEAR.
The last three years have been remarkably similar; at least as it pertains to
market expectations and how the actual markets can prove them wrong. In the
beginning of calendar years 2003, 2004, and 2005, many market participants
appeared convinced that interest rates were unreasonably low, and many managers
adjusted the risk profiles of their portfolios to reflect the coming of higher
rates and lower bond prices. In each year, the markets weathered the storms and
generated positive results, with price gains adding to the income generated.
Defensive strategies did not pan out.

Over the 12 months ended August 31, 2005, the fixed income markets rallied while
the Federal Reserve was in the midst of tightening credit by raising short-term
rates -- notably, the fed-funds rate. The tightening cycle started at the end of
June 2004, prior to the start of the fiscal year, and continues today. As of
August 31, 2005, the Federal Reserve raised rates by one quarter of a percentage
point at every one of its meetings -- a total of eight rate hikes that took the
fed-funds rate from 1.50% to 3.50%.

While the Federal Reserve's actions sent short-term yields in both the taxable
and the tax-exempt bond markets higher, the reaction of the intermediate and
long-term markets prompted Fed Chairman Alan Greenspan's "conundrum" comment
earlier this year. This type of sustained market rally through a Fed tightening
is highly unusual and is precisely what confounded many investors. In the
municipal market, yields on two-year, AAA-rated bonds increased by 1.2% during
the year, from 1.7%, to end the fiscal year near 2.9%. The crossover point where
rates were relatively flat year-over-year was in the 10-year maturity range,
where rates began and ended the year at about 3.5%. Longer rates fell. For
example, yields dropped by four tenths of a percent on 30-year AAA-rated
municipals, ending the fiscal year with yields of approximately 4.3% (source:
Municipal Market Data).

These divergent moves between short-term and long-term rates continued to
"flatten the yield curve." In the Treasury market, the difference between the 2-
and 30-year yields narrowed dramatically, from about two-and-a-half percentage
points to less than half of a percent at the end of the fiscal year. Some market
strategists have started discussing the prospects for, and implications of, an
inverted yield curve. Historically, an inverted yield curve has been associated
with the onset of an economic recession. The curve in the tax-exempt markets
flattened as well, but not quite as dramatically. While the difference between
2- and 30-year high-grade municipal bond yields started the year at 2.9%, it
narrowed by 1.5 percent, ending the year with a 1.4% differential. Historically,
when the Treasury market has inverted, the municipal market has maintained a
positively sloped curve.




Municipal bonds, particularly long-term bonds, traded weaker relative to
Treasuries during the year. Yields on 30-year AAA-rated municipals, measured as
a percentage of the yield on long Treasury bonds, started the fiscal year at
about 95%. By the end of June 2005, the ratio had increased above 100%. This
would be typical -- the market was rallying and the Treasury market led the way
toward lower yields. The municipal market recaptured some of that
underperformance in the last two months, ending the year with yields at about
98% of the long Treasury bond.

WHAT WAS THE INVESTMENT ENVIRONMENT LIKE DURING THE LAST 12 MONTHS IN ARIZONA,
CALIFORNIA, AND COLORADO?
Credit has performed very well this year, partially due to investors' desire to
seek higher yields, but also due to the fact that quality continued to improve
throughout the municipal market. A strong economic backdrop has largely been the
cause.

After several years of slow growth or even flat performance, Arizona's economy
provided solid growth for the last two years. The state has produced the second
fastest rate of job growth for 2005 to date, compared to all the states (Source:
The Business Journal Phoenix). These solid growth trends provided the state with
better-than-anticipated revenue flows. State revenues for the first eight months
of fiscal 2005 increased by nearly 17%. However, expenditure pressures will
continue to come from education, healthcare, and social services, limiting the
state's financial flexibility. In order to maintain a lid on taxes while
addressing these expenditure pressures, the governor has proposed various
non-recurring revenue sources to balance the 2006 budget.

                                       1


California had a similar pattern over the last two years, helping the state cope
with its structural deficit problems. State revenues were up approximately 17%
for the first eight months of fiscal 2005 (source: Municipal Market Data); with
personal and corporate tax receipts coming in ahead of budget. The absence of
any planned issuance of recovery bonds in the fiscal 2006 budget is credited to
the strong revenue flow. Despite the increase in tax receipts, the California
Department of Finance estimated that the budget gap will continue into next
fiscal year. This ongoing fiscal challenge is a major reason for the still-low
bond rating relative to other states (A2/A).

After experiencing a sharper economic downturn than the nation in recent years,
we believe Colorado is now recovering at a healthy pace. The state's employment
declines bottomed out in early 2004. With the resumption of moderate growth in
tax revenues, state finances appear to have improved over the past year and are
expected to remain relatively stable in fiscal 2006. Voter initiatives limit
state revenue and expenditure growth to the rate of population growth plus
inflation. Any tax revenues that exceed the constitutional limit must be
refunded. In November, voters will consider amendments to these initiatives.
Without these amendments, the governor's office projects that the state will
accrue a refund liability in fiscal 2006, with refund amounts growing
significantly in subsequent years.

Overall, municipal bond issuance has remained robust in 2005, and the western
states are no exception. Total national issuance in 2005 may even surpass the
record of $384 billion sold in 2003 if this pace remains. The drivers of this
record volume continue to be the low interest rate environment and the
flattening yield curve, both of which stimulate refunding activity. Arizona and
Colorado have experienced 12% and 7% growth in new issue volume year-to-date,
respectively. California new issuance levels are down by $5.5 billion, but
recall that last year the state issued over $10 billion in recovery bonds.
Excluding that issue, the state's new issue volume would have increased by 13%
(source: Municipal Market Data). Much of the increase in each state reflects
refunding activity (up 62% on a national basis).

HOW DID DELAWARE TAX-FREE ARIZONA INSURED FUND PERFORM DURING THE FISCAL YEAR?
For the fiscal year ended August 31, 2005, Delaware Tax-Free Arizona Insured
Fund returned 5.74% (Class A shares at net asset value with distributions
reinvested) and 0.96% (at maximum offer price with distributions reinvested).*
Class A shares (at net asset value with distributions reinvested) outperformed
the Lipper Arizona Municipal Debt Funds Universe Average, which returned 4.25%,
and the Lehman Brothers Municipal Bond Index, which returned 5.31% for the
12-month period, both of which exclude sales charges (source:
Lipper, Inc.).**

 *For complete annualized performance, see tables on pages 4, 6 and 8.
**A portion of the income from tax-exempt funds may be subject to the
  alternative minimum tax.



FOR EACH FUND, WHAT STRATEGIES INFLUENCED PERFORMANCE?
Returns in each of the Funds were aided by yield-curve positioning, credit
tightening, sector concentration, and security selection. While the Federal
Reserve raised short-term rates by increasing the fed-funds target rate,
long-term bond yields declined, as inflation remained tame during a period of
moderate growth. This resulted in what is termed a "flattening of the yield
curve," where the difference between long- and short-term rates narrows. The
Funds are positioned to take advantage of this environment, combining long
maturity bonds that participate in the rally and shorter-duration securities
with high coupons trading to short calls that are less price sensitive. This is
known as a "barbell" structure, and it generally aided in the returns for all
three Funds.

When the yield curve flattens and long-term interest rates decline, market
participants seek alternative sources of yield. This is often found in
lower-rated bonds, and as the market reaches for this yield, it causes the
credit curve to tighten and results in good performance for those securities.
Bonds rated A and BBB, and non-investment grade securities have all outperformed
high-grade and insured bonds in the municipal market over the past year. The
Funds benefited from allotment to these higher-risk credits.

                                       2


Two of our favored sectors, healthcare and higher education, have benefited from
both the market's reach for yield as well as positive fundamentals. The credit
and financial environments have been positive for hospitals, as they have
received favorable reimbursements from Medicare and the managed care industry.
The demographics provided by the baby boom generation have provided favorable
enrollment environment for colleges and universities while a recovering stock
market has bolstered endowments.

Individual security selection remains the heart of our investment process and is
the primary source of our excess returns. Some securities that have performed
well over the past year in Delaware Tax-Free Arizona Insured Fund include a
Maricopa healthcare issue for Catholic Healthcare West and an Arizona State
University bond. There was a refinancing of a Southern Arizona Capital
Facilities bond, issued for the University of Arizona, which resulted in a
significant upward price move during the fiscal year. In addition, two issues
for U.S. territories, one for Puerto Rico and one for the Virgin Islands,
performed well due to their longer maturities.

In Delaware Tax-Free California Fund, we are favorable on the tobacco bonds
enhanced by a state appropriation, and our Golden State Tobacco positions that
are backed by the State of California were among the Fund's best performing
securities. The bonds were pre-refunded to their first call date and appreciated
in price. Like Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free
California Fund owned a healthcare bond secured by Catholic Healthcare West,
which was a top performer for the year. Rounding out some of the other top
performers in California were two long maturity general obligation bonds
(California and San Diego Unified School District), a higher education revenue
bond that was refinanced (Pepperdine University), and a seasoned land
development issue (Southern California Logistics Airport Project).

Delaware Tax-Free Colorado Fund also had healthcare and education bonds
contribute to performance, as well as several refinancing events. Bonds issued
for Evangelical Lutheran and Vail Valley Medical Center were top healthcare
performers, and a bond issued for the Montessori Charter schools topped the list
for education bonds. There were several bonds refunded during the year, which
often generates a price pop due to the improved security standing of the issue.





DETRACTED FROM FUND PERFORMANCE?
Detracting from each of our Funds' performance, relative to its benchmark index,
was the significant decision to avoid the unenhanced tobacco sector. This
sector, in which we did not participate, has been the best performing sector in
the municipal bond market over the past year and the biggest influence on market
performance. The master settlement agreement between the major tobacco companies
and 46 states secures these bonds. However, the sector is subject to litigation
risk and, therefore, volatile. We are comfortable foregoing this potential
volatility in the Funds.

Airline securities significantly outperformed the municipal market this year
during the second and third quarters, which are a traditional busy season.
Although the Funds held several airport revenue bonds, we have been
underweighted in this sector and have generally avoided securities backed by
airline corporation revenues, as we are concerned about the long-term
fundamentals of the industry.

The decision to hold high-coupon, short-call legacy bonds provides an above
market yield to the portfolios and helps to balance the Funds' interest rate
exposure, offsetting the bonds with long maturities. However, during the fiscal
year it resulted in negligible price performance during market rallies due to
the short duration of the securities. This decision to hold these
underperforming securities also detracted from relative performance.

Returns reflect the reinvestment of all distributions and any applicable sales
charges as noted below. Performance for Class B and C shares, excluding sales
charges, assumes either that contingent deferred sales charges did not apply or
the investment was not redeemed.

The Fund offers Class A, B, and C shares. Class A shares are sold with a
front-end sales charge of up to 4.50% and have an annual distribution and
service fee of up to 0.25%.

Class B shares are sold with a contingent deferred sales charge that declines
from 4% to zero depending upon the period of time the shares are held. Class B
shares will automatically convert to Class A shares on a quarterly basis
approximately eight years after purchase. They are also subject to an annual
distribution and service fee of 1%. Lifetime and 10-year performance figures for
Class B shares reflect conversion to Class A shares after eight years.

Class C shares are sold with a contingent deferred sales charge of 1%, if
redeemed during the first 12 months. They are also subject to an annual
distribution and service fee of 1%.

An expense limitation was in effect for all classes of Delaware Tax-Free Arizona
Insured Fund during the periods shown. Performance would have been lower had the
expense limitation not been in effect.

The performance table does not reflect the deduction of taxes the shareholder
would pay on Fund distributions or redemptions of Fund shares.

A portion of the income from tax-exempt funds may be subject to the alternative
minimum tax.

Performance for other Fund classes will vary due to differing charges and
expenses. Returns plotted on the chart were as of the last day of each month
shown. The Lehman Brothers Municipal Bond Index is an unmanaged index that
generally tracks the performance of municipal bonds. An index is unmanaged and
does not reflect the costs of operating a mutual fund, such as the costs of
buying, selling, and holding securities. You cannot invest directly in an index.
The performance graph does not reflect the deduction of taxes the shareholder
would pay on Fund distributions or redemption of Fund shares. An expense

DISCLOSURE                       For the period March 1, 2005 to August 31, 2005
       OF FUND EXPENSES

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

The examples are based on an investment of $1,000 invested at the beginning of
the period and held for the entire period March 1, 2005 to August 31, 2005.

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second section of the tables shown, "Hypothetical 5% Return," provides
information about hypothetical account values and hypothetical expenses based on
the Funds' actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Funds' actual returns. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in a Fund and other funds.
To do so, compare this 5% hypothetical example with the 5% hypothetical examples
that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), redemption fees, or exchange fees. Therefore, the second
section of each table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have been
higher. Each Fund's actual expenses shown in each table reflect fee waivers in
effect. The expenses shown in each table assume reinvestment of all dividends
and distributions. "Expenses Paid During Period" are equal to the Funds'
annualized expense ratio, multiplied by the average account value over the
period, multiplied by 184/365 (to reflect the one-half year period).

     of the AICPA Audit and Accounting Guide for Investment Companies that
     required 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

These financial statements and related notes pertain to Delaware Tax-Free
Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free
Colorado Fund (each a "Fund" and, collectively, the "Funds"). The above Trusts
are open-end investment companies. The Funds are considered non-diversified
under the Investment Company Act of 1940, as amended. The Funds offer Class A,
Class B, and Class C shares. Class A shares are sold with a front-end sales
charge of up to 4.50%. Class B shares are sold with a contingent deferred sales
charge that declines from 4% to zero depending upon the period of time the
shares are held. Class B shares will automatically convert to Class A shares on
a quarterly basis approximately eight years after purchase. Class C shares are
sold with a contingent deferred sales charge of 1%, if redeemed during the first
12 months.

The investment objective of Delaware Tax-Free Arizona Insured Fund, Delaware
Tax-Free California Fund and Delaware Tax-Free Colorado Fund is to seek as high
a level of current income exempt from federal income tax and personal income tax
in their respective states, as is consistent with preservation of capital.

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

Security Valuation -- Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Short-term debt securities having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Open-end investment
companies are valued at their published net asset value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith under the direction of each Fund's Board of
Trustees. In determining whether market quotations are readily available or fair
valuation will be used, various factors will be taken into consideration, such
as market closures, aftermarket trading or significant events after local market
trading (e.g., government actions or pronouncements, trading volume or
volatility on markets, exchanges among dealers, or news events).

Federal Income Taxes -- Each Fund intends to continue to qualify for federal
income tax purposes as a regulated investment company and make the requisite
distributions to shareholders. Accordingly, no provision for federal income
taxes has been made in the financial statements.

Class Accounting -- Investment income and common expenses are allocated to the
classes of each Fund on the basis of "settled shares" of each class in relation
to the net assets of each Fund. Realized and unrealized gain (loss) on
investments are allocated to the various classes of each Fund on the basis of
daily net assets of each class. Distribution expenses relating to a specific
class are charged directly to that class.

Use of Estimates -- The preparation of financial statements in conformity with
U.S. generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

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




The Funds receive earnings credits from their custodian when positive balances
are maintained, which are used to offset custody fees. The expense paid under
the above arrangement is included in custodian fees on the Statements of
Operations with the corresponding expense offset shown as "expense paid
indirectly". The amount of this expense for the year ended August 31, 2005 was
as follows:


                                             Delaware Tax-Free
                                           Arizona Insured Fund
                                           --------------------
  Earnings credits                                  $713

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

                                             Delaware Tax-Free

6. FUND REORGANIZATION
Effective April 11, 2005, Delaware Tax-Free Arizona Insured Fund and Delaware
Tax-Free California Fund acquired all of the assets and assumed all of the
liabilities of Delaware Tax-Free Arizona Fund and Delaware Tax-Free California
Insured Fund, respectively, each an open-end investment company, pursuant to
Plans and Agreements of Reorganization (the "Reorganizations"). The shareholders
of Delaware Tax-Free Arizona Fund and Delaware Tax-Free California Insured Fund
received shares of the respective class of Delaware Tax-Free Arizona Insured
Fund and Delaware Tax-Free California Fund, respectively, equal to the aggregate
net asset value of their shares prior to the Reorganizations based on the net
asset value per share of the respective classes of Delaware Tax-Free Arizona
Insured Fund and Delaware Tax-Free California Fund.

The Reorganizations were treated as non-taxable events and, accordingly, each of
Delaware Tax-Free Arizona Insured Fund's and Delaware Tax-Free California Fund's
basis in the securities acquired reflected the historical cost basis as of the
date of transfer. The net assets, net unrealized appreciation and accumulated
net realized gain (loss) of Delaware Tax-Free Arizona Fund and Delaware Tax-Free
California Insured Fund as of the close of business on April 8, 2005, were as
follows:


                                                                   Net Unrealized         Accumulated Net
                                                Net Assets          Appreciation        Realized Gain/Loss
                                               -----------         --------------       ------------------
                                                                                  
  Delaware Tax-Free Arizona Fund               $28,887,777            $1,078,069           $(3,053,750)*

*Includes prior year capital loss carryforwards

The net assets of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free
California Fund prior to the Reorganizations were $134,516,468 and $46,891,287,
respectively. The combined net assets of Delaware Tax-Free Arizona Insured Fund
and Delaware Tax-Free California Fund after the Reorganization were $163,404,245
and $78,384,033, respectively.

7. LINE OF CREDIT
Each Fund, along with certain other funds in the Delaware Investments(R) Family
of Funds (the "Participants"), participates in a $183,100,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each fund's allocation of the entire facility. The Participants may
borrow up to a maximum of one third of their net assets under the agreement. The
Funds had no amounts outstanding as of August 31, 2005, or at any time during
the fiscal year.

8. CREDIT AND MARKET RISK
The Funds concentrate their investments in securities issued by municipalities.
The value of these investments may be adversely affected by new legislation
within the states, regional or local economic conditions, and differing levels
of supply and demand for municipal bonds. Many municipalities insure repayment
for their obligations. Although bond insurance reduces the risk of loss due to
default by an issuer, such bonds remain subject to the risk that market value
may fluctuate for other reasons and there is no assurance that the insurance
company will meet its obligations. These securities have been identified in the
Statements of Net Assets.




Each Fund may invest in advanced refunded bonds, escrow secured bonds or
defeased bonds. Under current federal tax laws and regulations, state and local
government borrowers are permitted to refinance outstanding bonds by issuing new
bonds. The issuer refinances the outstanding debt to either reduce interest
costs or to remove or alter restrictive covenants imposed by the bonds being
refinanced. A refunding transaction where the municipal securities are being
refunded within 90 days or less from the issuance of the refunding issue is
known as a "current refunding". "Advance refunded bonds" are bonds in which the
refunded bond issue remains outstanding for more than 90 days following the
issuance of the refunding issue. In an advance refunding, the issuer will use
the proceeds of a new bond issue to purchase high grade interest bearing debt
securities which are then deposited in an irrevocable escrow account held by an
escrow agent to secure all future payments of principal and interest and bond
premium of the advance refunded bond. Bonds are "escrowed to maturity" when the
proceeds of the refunding issue are deposited in an escrow account for
investment sufficient to pay all of the principal and interest on the original
interest payment and maturity dates. Bonds are considered "pre-refunded" when
the refunding issue's proceeds are escrowed only until a permitted call date or
dates on the refunded issue with the refunded issue being redeemed at the time,
including any required premium. Bonds become " when the rights and interests of
the bondholders and of their lien on the pledged revenues or other security
under the terms of the bond contract are substituted with an alternative source
of revenues (the escrow securities) sufficient to meet payments of principal and
interest to maturity or to the first call dates. Escrowed secured bonds will
often receive a rating of AAA from Moody's, S&P, and/or Fitch due to the strong
credit quality of the escrow securities and the irrevocable nature of the escrow
deposit agreement. The Tax-Free Insured Funds will purchase escrow secured bonds
without additional insurance only where the escrow is invested in securities of
the U.S. government or agencies or instrumentalities of the U.S. government.

Each Fund may invest up to 15% of its total assets in illiquid securities, which
may include securities with contractual restrictions on resale, securities
exempt from registration under Rule 144A of the Securities Act of 1933, as
amended, and other securities which may not be readily marketable. The relative
illiquidity of these securities may impair each Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so. At
August 31, 2005, there were no Rule 144A securities and no securities have been
determined to be illiquid under the Fund's Liquidity Procedures. While
maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day
functions of determining whether individual securities are liquid for purposes
of the Funds' limitation on investments in illiquid assets.

NOTES
       TO FINANCIAL STATEMENTS (CONTINUED)

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

10. TAX INFORMATION (UNAUDITED)
The information set forth below is for each Fund's fiscal year as required by
federal laws. Shareholders, however, must report distributions on a calendar
year basis for income tax purposes, which may include distributions for portions
of two fiscal years of a Fund. Accordingly, the information needed by
shareholders for income tax purposes will be sent to them in January of each
year. Please consult your tax advisor for proper treatment of this information.

For the fiscal year ended August 31, 2005, each Fund designates distributions
paid during the year as follows:

REPORT
       OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Shareholders and Board of Trustees
Voyageur Insured Funds - Delaware Tax-Free
  Arizona Insured Fund
Voyageur Mutual Funds -Delaware Tax-Free California Fund
Voyageur Mutual Funds II - Delaware Tax-Free Colorado Fund

We have audited the accompanying statements of net assets of Delaware Tax-Free
Arizona Insured Fund (one of the series constituting Voyageur Insured Funds),
Delaware Tax-Free California Fund (one of the series constituting Voyageur
Mutual Funds), and Voyageur Mutual Funds II (comprised of Delaware Tax-Free
Colorado Fund) (the "Funds") as of August 31, 2005, and the related statements
of operations for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended. These financial statements
and financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, evaluating the overall financial
statement presentation. Our audit procedures included confirmation of securities
owned as of August 31, 2005, by correspondence with the custodian and brokers or
by other appropriate auditing procedures where replies from brokers were not
received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Delaware Tax-Free Arizona Insured Fund of Voyageur Insured Funds, the Delaware
Tax-Free California Fund of Voyageur Mutual Funds, and the Delaware Tax-Free
Colorado Fund of Voyageur Mutual Funds II at August 31, 2005, the results of
their operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended, and their financial highlights
for each of the five years in the period then ended, in conformity with U.S.
generally accepted accounting principles.

BOARD CONSIDERATION OF DELAWARE TAX-FREE ARIZONA INSURED FUND, DELAWARE TAX-FREE
CALIFORNIA FUND AND DELAWARE TAX-FREE COLORADO FUND INVESTMENT ADVISORY
AGREEMENT

At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Boards of
Trustees, including a majority of disinterested or independent Trustees,
approved the renewal of the Investment Advisory Agreements for the Delaware
Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware
Tax-Free Colorado Fund (each a "Fund" and together the "Funds"). In making its
decision, the Board considered information furnished throughout the year at
regular Board meetings, as well as information prepared specifically in
connection with the Annual Meeting. Information furnished and discussed
throughout the year included reports detailing Fund performance, investment
strategies, expenses, compliance matters and other services provided by Delaware
Management Company ("DMC"), the investment advisor. Information furnished
specifically in connection with the Annual Meeting included materials provided
by DMC and its affiliates ("Delaware Investments") concerning, among other
things, the level of services provided to the Funds, the costs of such services
to the Funds, economies of scale and the financial condition and profitability
of Delaware Investments. In addition, in connection with the Annual Meeting, the
Board separately received and reviewed independent historical and comparative
reports prepared by Lipper Inc. ("Lipper"), an independent statistical
compilation organization. The Lipper reports compared each Fund's investment
performance and expenses with those of other comparable mutual funds. The Board
also requested and received certain supplemental information regarding
management's policy with respect to advisory fee levels and its philosophy with
respect to breakpoints; the structure of portfolio manager compensation; the
investment manager's profitability organized by client type, including the
Funds; and any constraints or limitations on the availability of securities in
certain investment styles which might inhibit the advisor's ability to fully
invest in accordance with each Fund's policies.

In considering such materials, the independent Trustees received assistance and
advice from and met separately with independent counsel and representatives from
Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman
of the Delaware Investments(R) Family of Funds, and Chairman and Chief Executive
Officer of the investment advisor, was present to respond to questions raised by
Lipper and the independent Trustees. While the Board considered the Investment
Advisory Agreements for all of the funds in the Delaware Investments Family of
Funds at the same Board meeting, information was provided and considered by the
Board for each fund individually. In approving the continuance of the Investment
Advisory Agreements for the Funds, the Board, including a majority of
independent Trustees, determined that the existing advisory fee structure was
fair and reasonable and that the continuance of the Investment Advisory
Agreements was in the best interests of the Funds and their shareholders. While
attention was given to all information furnished, the following discusses the
primary factors relevant to the Board's deliberations and determination,
including those relating to the selection of the investment advisor and the
approval of the advisory fee.

NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services
provided by Delaware Investments to the Funds and their shareholders. In
reviewing the nature, extent and quality of services, the Board emphasized
reports furnished to it throughout the year at regular Board meetings covering
matters such as the compliance of portfolio managers with the investment
policies, strategies and restrictions for the Funds, the compliance of
management personnel with the Code of Ethics adopted throughout the Delaware
Investments(R) Family of Funds complex, the adherence to fair value pricing
procedures as established by the Board, and the accuracy of net asset value
calculations. The Board noted that it was pleased with the current staffing of
the Funds' investment advisor during the past year, the emphasis on research and
the compensation system for advisory personnel. Favorable consideration was
given to DMC's efforts to maintain, and in some instances increase, financial
and human resources committed to fund matters. Other factors taken into account
by the Board were Delaware Investments' preparedness for, and response to, legal
and regulatory matters. The Board also considered the transfer agent and
shareholder services provided to Fund shareholders by Delaware Investments'
affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate
of the DALBAR Pyramid Award in four of the last six years and the continuing
expenditures by Delaware Investments to increase and improve the scope of
shareholder services. Additionally, the Board noted the extent of benefits
provided to Fund shareholders for being part of the Delaware Investments Family
of Funds, including the privilege to exchange investments between the same class
of funds without a sales charge, the ability to reinvest Fund dividends into
other funds and the privilege to combine holdings in other funds to obtain a
reduced sales charge. The Board was satisfied with the nature, extent and
quality of the overall services provided by Delaware Investments.




INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC
and the Funds. The Board was pleased by DMC's investment performance, noting
Barron's ranking of the Delaware Investments Family of Funds in the top quartile
of mutual fund families for 2002 - 2004. The Board placed significant emphasis
on the investment performance of the Funds in view of its importance to
shareholders. While consideration was given to performance reports and
discussions with portfolio managers at Board meetings throughout the year,
particular attention in assessing performance was given to the Lipper reports
furnished for the Annual Meeting. The Lipper reports prepared for each Fund
showed the investment performance of its Class A shares in comparison to a group
of similar funds as selected by Lipper (the "Performance Universe"). A fund with
the highest performance is ranked first, and a fund with the lowest is ranked
last. The highest/best performing 25% of funds in the Performance Universe make
up the first quartile; the next 25% -- the second quartile; the next 25% -- the
third quartile; and the lowest/worst performing 25% of funds in the Performance
Universe make up the fourth quartile. Comparative annualized performance for the
Funds was shown for the past one-, three-, five- and 10-year periods, as
applicable, ended February 28, 2005. The Board noted its objective that each
Fund's performance be at or above the median of its Performance Universe. The
following paragraphs summarize the performance results for the Funds and the
Board's view of such performance.

DELAWARE TAX-FREE ARIZONA INSURED FUND -- The Performance Universe for this Fund
consisted of the Fund and all retail and institutional Arizona municipal debt
funds as selected by Lipper. The Lipper report comparison showed that the Fund's
total return for the one-, five- and 10-year periods was in the first quartile
of such Performance Universe. The report further showed that the Fund's total
return for the three year period was in the second quartile. The Board was
satisfied with such performance.

OTHER
       FUND INFORMATION (CONTINUED)

COMPARATIVE EXPENSES. The Board considered expense comparison data for the
Delaware Investments(R) Family of Funds, Delaware Investments' institutional
separate account business and other lines of business at Delaware Investments.
The Board stated its belief that, given the differing level of service provided
to Delaware Investments' various clients and other factors that related to the
establishment of fee levels, variations in the levels of fees and expenses were
justified. The Board placed significant emphasis on the comparative analysis of
the management fees and total expense ratios of each Fund compared with those of
a group of similar funds as selected by Lipper (the "Expense Group") and among
the other Delaware Investments funds. In reviewing comparative costs, each
Fund's contractual management fee and the actual management fee incurred by the
Fund were compared with the contractual management fees (assuming all funds in
the Expense Group were similar in size to the Fund) and actual management fees
(as reported by each fund) of other funds within the Expense Group, taking into
effect any applicable breakpoints and fee waivers. Each Fund's total expenses
were also compared with those of its Expense Group. The Lipper total expenses,
for comparative consistency, were shown by Lipper for Class A shares and
compared total expenses including 12b-1 and non-12b-1 service fees. The Board
noted its objective to limit each Fund's total expense ratio to an acceptable
range as compared to the median of the Expense Group. The following paragraphs
summarize the expense results for the Funds and the Board's view of such
expenses.

DELAWARE TAX-FREE ARIZONA INSURED FUND -- The expense comparisons for the Fund
showed that its management fee was in the quartile with the second highest
expenses of its Expense Group and its total expenses were in the quartile with
the highest expenses of its Expense Group. The Board noted that the Fund's total
expenses were not in line with the Board's objective. In evaluating the total
expenses, the Board considered waivers in place through March 2006. The Board
was satisfied with management's efforts to improve the Fund's total expense
ratio and bring it in line with the Board's objective.

DELAWARE TAX-FREE CALIFORNIA FUND -- The expense comparisons for the Fund showed
that its management fee and total expenses were in the quartile with the lowest
expenses of its Expense Group. The Board was satisfied with the management fees
and total expenses of the Fund in comparison to its Expense Group as shown in
the Lipper report.

DELAWARE TAX-FREE COLORADO FUND -- The expense comparisons for the Fund showed
that its management fee and total expenses were in the quartile with the highest
expenses of its Expense Group. The Board noted that the Fund's total expenses
were not in line with the Board's objective. In evaluating the total expenses,
the Board considered waivers in place through October 2005. The Board was
satisfied with management's efforts to improve the Fund's total expense ratio
and bring it in line with the Board's objective.

MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any,
realized by Delaware Investments in connection with the operation of the Funds.
In this respect, the Board reviewed the Investment Management Profitability
Analysis that addressed the overall profitability of Delaware Investments'
business in providing management and other services to each of the individual
funds and the Delaware Investments Family of Funds as a whole. Specific
attention was given to the methodology followed in allocating costs for the
purpose of determining profitability. Management stated that the level of
profits of Delaware Investments, to a certain extent, reflected operational cost
savings and efficiencies initiated by Delaware Investments. The Board considered
Delaware Investments' expenditures to improve services provided to fund
shareholders and to meet additional regulatory and compliance requirements
resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also
considered the extent to which Delaware Investments might derive ancillary
benefits from fund operations, including the potential for procuring additional
business as a result of the prestige and visibility associated with its role as
service provider to the Delaware Investments Family of Funds, the benefits from
allocation of fund brokerage to improve trading efficiencies and the use of
"soft" commission dollars to pay for proprietary and non-proprietary research.
At the Board's request, management also provided information relating to
Delaware Investments' profitability by client type. The information provided set
forth the revenue, expenses and pre-tax income/loss attributable to the Delaware
Investments Family of Funds, Delaware Investments' separate account business and
other lines of business at Delaware Investments. Emphasis was given to the level
and type of service provided to the various clients. The Board was satisfied
with the level of profits realized by Delaware Investments from its
relationships with the Funds and the Delaware Investments Family of Funds.

ECONOMIES OF SCALE. The Trustees considered whether economies of scale are
realized by Delaware Investments as each Fund's assets increase and the extent
to which any economies of scale are reflected in the level of management fees
charged. The Trustees took into account the standardized advisory fee pricing
and structure approved by the Board and shareholders as part of a complex-wide
shareholder meeting conducted in 1998/1999. At that time, Delaware Investments
introduced breakpoints to account for management economies of scale. The Board
noted that the fee under each Fund's management contract fell within the
standard structure. Although the Funds have not reached a size at which they can
take advantage of breakpoints, the Board recognized that the fee was structured
so that when the Funds grow, economies of scale may be shared.

PLEASE DESCRIBE THE OVERALL MARKET CONDITIONS DURING
THE FISCAL YEAR.
The last three years have been remarkably similar; at least as it pertains to
market expectations and how the actual markets can prove them wrong. In the
beginning of calendar years 2003, 2004, and 2005, market participants were
convinced that interest rates were unreasonably low, and many managers adjusted
the risk profiles of their portfolios to reflect the coming of higher rates and
lower bond prices. In each year, the markets weathered the storms and generated
positive results, with price gains adding to the income generated. Defensive
strategies did not pan out.

Over the last 12 months ended August 31, 2005, the fixed income markets rallied
while the Federal Reserve was in the midst of tightening credit by raising
short-term rates - notably, the fed funds rate. The tightening cycle started at
the end of June 2004, prior to the start of the fiscal year, and continues
today. As of August 31, 2005, the Federal Reserve raised rates by one quarter of
a percentage point at every one of its meetings - a total of eight rate hikes
that took the fed funds rate from 1.50% to 3.50%.

While the Federal Reserve's actions sent short-term yields in both the taxable
and the tax-exempt bond markets higher, the reaction of the intermediate and
long-term markets prompted Fed Chairman Alan Greenspan's "conundrum" comment
earlier this year. This type of sustained market rally through a Fed tightening
is highly unusual and is precisely what confounded many investors. In the
municipal market, yields on two-year, AAA-rated bonds increased by 1.2% during
the year, from 1.7% to end the fiscal year near 2.9%. The crossover point where
rates were relatively flat year-over-year was in the 10-year maturity range,
where rates began and ended the year at about 3.5%. Longer rates fell. For
example, yields dropped by four tenths of a percent on 30-year AAA-rated
municipals, ending the fiscal year with yields of approximately 4.3%. (source:
Municipal Market Data)

These divergent moves between short-term and long-term rates continued to
flatten the yield curve. Historically, an inverted yield curve has been
associated with the onset of an economic recession. The curve in the tax-exempt
markets flattened as well, but not quite as dramatically. While the difference
between 2- and 30-year high-grade municipal bonds started the year at 2.9%, it
narrowed by 1.5%, ending the year with a 1.4% differential (Source: Municipal
Market Data). Historically, when the Treasury market has inverted, the municipal
market has maintained a positively sloped curve.

Municipal bonds, particularly long-term bonds, traded weaker relative to
Treasuries during the year. Yields on 30-year AAA-rated municipals, measured as
a percentage of the yield on long Treasury bonds, started the fiscal year at
about 95%. By the end of June 2005, the ratio had increased above 100%. This
would be typical - the market was rallying and the Treasury market led the way
toward lower yields. The municipal market recaptured some of that
underperformance in the last two months, ending the year with yields at about
98% of the long Treasury bond.

In our opinion, credit has performed very well this year, partially due to
investors' desire to seek higher yields, but also due to the fact that quality
continued to improve throughout the municipal market. A strong economic backdrop
has largely been the cause. Revenue recovery has firmly taken hold and is easing
the transition to structural budget balance for most states. Driving the revenue
gains, total non-farm payrolls increased 1.7% in the 12-months ending August
2005, while the unemployment rate decreased from 5.5% to 5.0%(source: US
Department of Labor). As a result, most states are experiencing
better-than-budgeted growth to date for fiscal 2005, which is providing
additional resources to balance fiscal 2006 and lending support for growing
spending demands.

For the first eight months of fiscal 2005, state revenues were up a total of
9.5%, with personal income tax and sales tax increases leading the way.
Additional factors contributing to positive revenue trends were conservative
budget forecasting, low interest rates and the strong real estate market
(source: Municipal Market Data).

Spending pressures still loom, threatening budget stability. The federal
government will likely be a source of budget strain in the coming years as it
grapples with its own budget deficit. States may also have to deal with
traditional budget issues such as social service programs and education funding.
The future in most states will depend on economic performance, sustained
structural balance, and progress in re-building financial/budget reserves.

Municipal bond issuance remained robust in 2005. As of August 31, 2005, issuance
totaled $275.49 billion, a 13.10% increase over the same period last year. Total
issuance in 2005 may even surpass the record of $384 billion sold in 2003 if
this
                                       1


pace continues. Drivers of this record volume continue to be the low interest
rate environment and the flattening yield curve, both of which stimulate
refunding activity. Year-to-date, refunding activity was up 62.1% from the same
period a year ago. At the same time, low rates are attractive for new money
sales, which increased 12.8% (source: Municipal Market Data). The healthcare
sector has seen significant increase in new-money issuance due to the sector's
improved credit conditions and need to invest in facilities. Other sectors that
registered significant jumps in issuance included transportation and general
purpose bonds.

WHAT WAS THE ECONOMIC AND MUNICIPAL MARKET ENVIRONMENT IN MINNESOTA DURING THE
LAST 12 MONTHS?
Minnesota enjoys a deep and diverse economy, supported by several regional
economic centers and anchored by the Minneapolis-St. Paul MSA. However,
Minnesota's manufacturing concentration and the state's reliance on the income
tax revenue generated by those jobs combined to hit the state hard during and
after the manufacturing-led 2001 recession. Employment increased 1.5% in the
past twelve months through August 2005. The recovery is broad, with gains in
services, construction and manufacturing. Minnesota's unemployment rate has also
improved to 3.6% as of August 2005 (source: Municipal Market Data).

In fiscal 2004, revenues came in above estimates. The additional revenues were
primarily in personal income tax, a sharp departure from the last several years
when actual receipts from the personal income tax continually came in below
forecast. According to the state, economically sensitive revenues continue to
perform close to forecast, with better-than-expected growth in corporate profits
offsetting slightly below average growth in more consumer-based revenues such as
sales. During the first nine months of fiscal 2005, total revenues grew almost
6% (source: Municipal Market Data).

For the first eight months of 2005, new issuance in Minnesota was up 25.3% over
the same period a year ago. As of August 31, 2005, Minnesota issued $4.9 billion
of debt compared to $3.9 billion a year ago. One of the larger issuances was
from Minneapolis & St. Paul Minnesota Metropolitan Airports (source: The Bond
Buyer).

HOW DID DELAWARE TAX-FREE MINNESOTA INSURED FUND PERFORM DURING THE FISCAL YEAR?
For the fiscal year ended August 31, 2005, Delaware Tax-Free Minnesota Insured
Fund returned 5.42% (Class A shares at net asset value with distributions
reinvested) and 0.67% (at maximum offer price with distributions reinvested).
Class A shares (at net asset value with distributions reinvested) outperformed
both the Lipper Minnesota Municipal Debt Funds Average, which returned 4.33%,
and the Lehman Brothers Municipal Bond Index, which returned 5.31% for the
12-month period. (source: Lipper, Inc.).*

                                       2

FOR EACH FUND, WHAT STRATEGIES CONTRIBUTED TO FUND PERFORMANCE?
The Funds' returns were generally aided by yield curve positioning, credit
spread tightening, sector concentration, and security selection. The relative
contribution of these first three components varies based on the individual
Fund's mandate asset forth in its prospectus. The fourth factor, security
selection, is the heart of our investment process and is the primary source of
our returns.

While the Federal Reserve raised short-term rates, long-term bond yields
declined as inflation remained tame during a period of moderate growth. This
resulted in what is termed as a "flattening of the yield curve," where the
difference between long- and short-term rates narrows. The Funds are positioned
to take advantage of this environment, combining long maturity bonds and shorter
duration securities with high coupons trading to short calls that are less price
sensitive. This is known as a "barbell" portfolio structure, and it generally
aided our performance.

When the yield curve flattens and long-term interest rates decline, market
participants seek alternative sources of yield. This is often found in
lower-rated bonds, and as the market reaches for this yield it causes the credit
curve to tighten and results in good performance for those securities.
Securities rated A, BBB and non-investment grade have all outperformed
high-grade and insured bonds in the municipal market over the past year. The
Funds benefited from a meaningful allotment to these credits.

Two of our favored sectors, healthcare and higher education, benefited from both
the market's reach for yield as well as positive fundamentals. The credit and
financial environments have been positive for hospitals, as they have received
favorable reimbursements from Medicare. The demographics provided by the baby
boom generation have provided favorable enrollment trends at colleges and
universities, while recovering stock market has bolstered endowments. Despite a
structural deficit, various bonds issued by the Commonwealth of Puerto Rico also
performed well during the period.

The Delaware Tax-Free Minnesota Fund has the broadest mandate of the four
Minnesota funds and has therefore been able to participate in all four sources
of return. The Fund's portfolio is structured as a "barbell"; it has a
meaningful allotment in mid-to-lower investment grade credits and therefore
participated in some of the better performing sectors, but it also received a
significant contribution from the high-quality, pre-refunded sector. That
contribution came primarily from the refinancing (pre-refunding) of a large
position of Fairview Hospital in Minneapolis and provided an above market price
appreciation on that bond. This leaves the Fund with a security escrowed in U.S.
government securities and an above market coupon that we will collect for years
to come.

Delaware Tax-Free Minnesota Insured Fund was well positioned for a flattening of
the yield curve with a significant allocation of bonds having maturities 15
years and longer. Legacy bonds that have short due dates or short calls complete
the barbell. The Fund's insured mandate limits it from participating fully in
the credit spread tightening of lower rated bonds and the associated sectors of
the market. The Fund is allowed to own up to 20% of its securities in
non-insured bonds and we maximized our use of non-insureds during the period to
gain excess returns.

Delaware Tax-Free Minnesota Intermediate Fund was also well positioned to
benefit from a flatter yield curve, but due to its intermediate mandate, the
long end of the barbell is structured in the 10- to 20-year part of the curve.
The Fund has also benefited from an allocation to Single A and Triple BBB rated
securities and some of their associated sectors. Excess returns were found in
the Healthcare sector in Park Nicollet and Allina Health Systems.

While Delaware Minnesota High-Yield Municipal Bond Fund's structure is that of a
barbell, the securities in it are less sensitive to interest rate movements and
more dependent on credit quality. This fund not only has a healthy allotment in
A and BBB bonds, but also in non-investment grade securities. It owns both
BB-rated bonds and comparable quality non-rated securities. These rating classes
and their corresponding sectors have generally led the way in the municipal
market over the last year.

CAN YOU NAME SOME KEY HOLDINGS IN THE FUNDS?
In the Delaware Tax-Free Minnesota Fund, other hospital positions that have
performed well in terms of total return are Benedictine Health Systems in
Duluth, Park Nicollet Health Systems in St. Louis Park and St. Francis Regional
Medical Center in Shakopee. Also aiding in performance were multifamily housing
projects in Minneapolis, St. Cloud, Stillwater, and Hutchinson.

In the Delaware Tax-Free Minnesota Insured Fund, securities in this category
were some of the same healthcare systems previously mentioned such as
Benedictine and Park Nicollet, but Allina Health System in Minneapolis also
joined them. Also in the Fund were bonds for an International Paper plant
located

                                       3

in Sartell. There were plenty of AAA securities including the insured
Minneapolis Airport bonds, insured Southern Minnesota Municipal Power Agency
bonds, and the escrowed Dakota & Washington Counties single family housing
bonds. The Fund also owned large positions in Fairview Hospital that were
pre-refunded during the period and appreciated in price.

In the Delaware Tax-Free Minnesota Intermediate Fund, securities for the
Healtheast Hospital Project in St. Paul also provided additional return when
Moody's upgraded the bonds to investment grade. Other significant contributors
to performance in this fund were various higher education bonds such as the
Walker Art Center in Minneapolis and the Minnesota College of Art & Design,
along with securities for the State University Foundation Project in St. Cloud.
The top two performers were a multifamily housing project in Minneapolis for the
Trinity Apartments and the aforementioned Fairview Hospital bonds that were
refinanced.

In the Delaware Tax-Free Minnesota High-Yield Municipal Bond Fund, excess
returns have come from a variety of securities for hospitals, multifamily
housing projects, corporate backed debt, higher education institutions and
senior living facilities. The senior living bonds can be for either one or some
combination of independent living, assisted living and skilled nursing
facilities. Holdings included, a nursing home known as the Forest Health
Services Project, the Jones-Harrison Residence in Minneapolis and in Twin
Valley, the Living Options community. Other individual securities included the
previously mentioned hospitals or health systems such as Benedictine, Allina,
Park Nicollet, St. Francis Medical Center and the pre-refunded Fairview Hospital
bonds. We also held bonds financing various multifamily housing projects such as
Trinity Apartments and Grant Street Apartments in Minneapolis, along with the
Evergreen Apartments in Hutchinson. Corporate backed debt has contributed
through securities such as industrial development bonds for International Paper
and special facility bonds for Northwest Airlines.

WHAT DETRACTED FROM FUND PERFORMANCE?

Detracting from our Funds' performance relative to the benchmark index was the
decision to avoid the unenhanced tobacco sector. This sector, which we did not
participate in, has been the best performing sector in the municipal bond market
over the past year and the biggest influence on market performance. The master
settlement agreement between the major tobacco companies and 46 states secures
unenhanced tobacco bonds. The sector is subject to litigation risk, and thus may
add volatility. We are comfortable foregoing a potential source of volatility in
the Funds.

Airline securities significantly outperformed the municipal market this year
during the second and third quarter, which is a traditional busy season.
Although the Funds held several airport revenue bonds, we have been under weight
in this sector and we have generally avoided securities backed by airport
corporation revenues. We are concerned about the long-term fundamentals of the
industry.

The decision to hold high coupon, short-call bonds provides an above market
yield to the portfolios and helps to balance the Funds' interest rate exposure,
offsetting the bonds with long maturities. However, during the fiscal year it
resulted in negligible price performance during market rallies due to the short
duration of the securities. The decision to hold these underperfoming bonds
resulted in weakened performance, relative to the benchmark and our peers.

GLOSSARY
AVERAGE MATURITY: For a bond fund, this is the weighted average of the stated
maturity dates of the portfolio's securities. In general, the longer the average
maturity, the greater the fund's sensitivity to interest rate changes, which can
mean greater price fluctuation. A shorter average maturity usually means less
interest rate sensitivity and, consequently, a less volatile portfolio.

BASIS POINT: One one-hundredth of one percentage point,
or 0.01%.

DURATION: A measure of a bond or bond fund's sensitivity to changes in interest
rates. All else being equal, a fund with a duration of four years would fall
about 4% in response to a one-percentage-point rise in rates, and vice versa.

SPREAD: the difference between any two prices or yields.

YIELD CURVE: A curve that shows the relationship between yields and maturity
dates for a set of similar bonds, usually Treasuries, at a given point in time.

PERFORMANCE SUMMARY
       DELAWARE TAX-FREE MINNESOTA INSURED FUND

The performance data quoted represent past performance; past performance does
not guarantee future results. Investment return and principal value will
fluctuate so your shares, when redeemed, may be worth more or less than their
original cost. Current performance may be lower or higher than the performance
data quoted. Please obtain the performance data for the most recent month end by
calling 800 523-1918 or visiting our Web site at www.delawareinvestments.com/
performance. You should consider the investment objectives, risks, charges and
expenses of the investment carefully before investing. The Delaware Tax-Free
Minnesota Insured Fund prospectus contains this and other important information
about the Fund. Please request a prospectus by calling 800 523-1918. Read it
carefully before you invest or send money. Performance includes reinvestment of
all distributions and is subject to change. A rise/fall in the interest rates
can have a significant impact on bond prices and the NAV (net asset value) of
the fund. Funds that invest in bonds can lose their value as interest rates rise
and an investor can lose principal.

Returns reflect the reinvestment of all distributions and any applicable sales
charges as noted below. Performance for Class B and C shares, excluding sales
charges, assumes either contingent deferred sales charges did not apply or the
investment was not redeemed.

The Fund offers Class A, B, and C shares. Class A shares are sold with a
front-end sales charge of up to 4.50% and have an annual distribution and
service fee of up to 0.25%.

Class B shares are sold with a contingent deferred sales charge that declines
from 4% to zero depending upon the period of time the shares are held. Class B
shares will automatically convert to Class A shares on a quarterly basis
approximately eight years after purchase. They are also subject to an annual
distribution and service fee of 1%. Lifetime and 10-year performance figures for
Class B shares reflect conversion to Class A shares after eight years.

Class C shares are sold with a contingent deferred sales charge of 1%, if
redeemed during the periods shown. They are also subject to an annual
distribution and service fee of 1%.

An expense limitation was in effect for all classes of Delaware Tax-Free
Minnesota Insured Fund during the periods shown. Performance would have been
lower had the expense limitation not been in effect.

The performance table does not reflect the deduction of taxes the shareholder
would pay on Fund distributions or redemptions of Fund shares.

A portion of the income from tax-exempt funds may be subject to the alternative
minimum tax.

DISCLOSURE                       For the Period March 1, 2005 to August 31, 2005
       OF FUND EXPENSES

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

The examples are based on an investment of $1,000 invested at the beginning of
the period and held for the entire period March 1, 2005 to August 31, 2005.

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second section of the tables shown, "Hypothetical 5% Return," provides
information about hypothetical account values and hypothetical expenses based on
the Funds' actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Funds' actual returns. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in a Fund and other funds.
To do so, compare this 5% hypothetical example with the 5% hypothetical examples
that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), redemption fees, or exchange fees. Therefore, the second
section of each table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have been
higher. Each Fund's actual expenses shown in each table reflect fee waivers in
effect. The expenses shown in each table assume reinvestment of all dividends
and distributions. "Expenses Paid During Period" are equal to the Fund's
annualized expense ratio, multiplied by the average account value over the
period, multiplied by 184/365 (to reflect the one-half year period).

(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 as an
    adjustment to interest income. 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 these changes in accounting.

(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 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 as an
    adjustment to interest income. 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 these changes in accounting.

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

NOTES                                    DELAWARE MINNESOTA MUNICIPAL BOND FUNDS
   TO FINANCIAL STATEMENTS               August 31, 2005

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 business trust and offers the Delaware Tax-Free
Minnesota Fund. Voyageur Intermediate Tax Free Funds (the "Trust") is organized
as a Delaware statutory trust and offers the Delaware Tax-Free Minnesota
Intermediate Fund. These financial statements and related notes pertain to
Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund,
Delaware Tax-Free Minnesota Intermediate Fund and Delaware Minnesota High-Yield
Municipal Bond Fund (each referred to as a "Fund" or, collectively, the
"Funds"). The above Trusts are open-end investment companies. The Funds are
considered non-diversified under the Investment Company Act of 1940, as amended,
and offer Class A, Class B, and Class C shares. Class A shares are sold with a
front-end sales charge of up to 4.50% for Delaware Tax-Free Minnesota Fund,
Delaware Tax-Free Minnesota Insured Fund and Delaware Minnesota High-Yield
Municipal Bond Fund and up to 2.75% for Delaware Tax-Free Minnesota Intermediate
Fund. Class B shares are sold with a contingent deferred sales charge that
declines from 4% to zero for Delaware Tax-Free Minnesota Fund, Delaware Tax-Free
Minnesota Insured Fund and Delaware Minnesota High-Yield Municipal Bond Fund and
that declines from 2% to zero for Delaware Tax-Free Minnesota Intermediate Fund,
depending upon the period of time the shares are held. Class 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 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, aftermarket trading or significant events after local market
trading (e.g., government actions or pronouncements, trading volume or
volatility on markets, exchanges among dealers, or news events).

Federal Income Taxes -- Each Fund intends to continue to qualify for federal
income tax purposes as a regulated investment company and make the requisite
distributions to shareholders. Accordingly, no provision for federal income
taxes has been made in the financial statements.

Class Accounting -- Investment income and common expenses are allocated to the
classes of each Fund on the basis of "settled shares" of each class in relation
to the net asset of each Fund. Realized and unrealized gain (loss) on
investments are allocated to the various classes of each Fund on the basis of
daily net assets of each class. Distribution expenses relating to a specific
class are charged directly to that class.

Use of Estimates -- The preparation of financial statements in conformity with
U.S. generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and each reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.


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

The Funds receive earnings credits from their custodian when positive cash
balances are maintained, which are used to offset custody fees. The expense paid
under the above arrangement is included in custodian fees on the Statements of
Operations with the corresponding expenses offset shown as "expense paid
indirectly". The amount of this expense for the year ended August 31, 2005 was
as follows:

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

                                          Delaware Tax-Free
                                             Minnesota
                                            Insured Fund
                                          -----------------
  On the first $500 million                   0.500%
  On the next $500 million                    0.475%
  On the next $1.5 billion                    0.450%
  In excess of $2.5 billion                   0.425%

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

                                         Delaware Tax-Free

    net assets (per annum)                     0.75%

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. Effective May
19, 2005, each Fund pays DSC a monthly fee computed at the annual rate of 0.04%
of each Fund's average daily net assets for accounting and administration
services. Prior to May 19, 2005, each Fund paid DSC a monthly fee based on
average net assets subject to certain minimums for accounting and administration
services. Each Fund pays DSC a monthly fee based on the number of shareholder
accounts for dividend disbursing and transfer agent services.

Pursuant to a distribution agreement and distribution plan, each Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.25% of the average daily net
assets of the Class A shares and 1.00% of the average daily net assets of the
Class B and C shares. DDLP has contracted to waive distribution fees through
October 31, 2005 in order to prevent distribution fees of Class A from exceeding
0.15% of average daily net assets for Delaware Tax-Free Minnesota Intermediate
Fund.

4. DIVIDEND AND DISTRIBUTION INFORMATION
Income and long-term capital gain distributions are determined in accordance
with federal income tax regulations, which may differ from U.S. generally
accepted accounting principles. Additionally, net short-term gains on sales of
investment securities are treated as ordinary income for federal income tax
purposes. The tax character of dividends and distributions paid during the years
ended August 31, 2005 and 2004 was as follows:

                                        Delaware Tax-Free

The differences between book basis and tax basis components of net assets are
primarily attributable to tax deferral of losses on wash sales and tax treatment
of market discount on debt instruments. For financial reporting purposes,
capital accounts are adjusted to reflect the tax character of permanent book/tax
differences. Reclassifications are primarily due to tax treatment of market
discount on certain debt instruments. Results of operations and net assets were
not affected by these reclassifications. For the year ended August 31, 2005, the
Funds recorded the following reclassifications:

6. LINE OF CREDIT
Each Fund, along with certain other funds in the Delaware Investments(R)
Family of Funds (the "Participants"), participates in a $183,100,000 revolving
line of credit facility to be used for temporary or emergency purposes as an
additional source of liquidity to fund redemptions of investor shares. The
Participants are charged an annual commitment fee, which is allocated across the
Participants on the basis of each fund's allocation of the entire facility. The
Participants may borrow up to a maximum of one third of their net assets under
the agreement. The Funds had no amounts outstanding as of August 31, 2005 or at
any time during the year.

7. CREDIT AND MARKET RISK
The Funds concentrate their investments in securities issued by municipalities,
mainly in Minnesota. The value of these investments may be adversely affected by
new legislation within the state, regional or local economic conditions, and
differing levels of supply and demand for municipal bonds. Many municipalities
insure repayment for their obligations. Although bond insurance reduces the risk
of loss due to default by an issuer, such bonds remain subject to the risk that
market value may fluctuate for other reasons and there is no assurance that the
insurance company will meet its obligations. These securities have been
identified in the Statements of Net Assets.

Each Fund may invest in inverse floating rate securities ("inverse floaters"), a
type of derivative tax-exempt obligation with floating or variable interest
rates that move in the opposite direction of short-term interest rates, usually
at an accelerated speed. Consequently, the market values of inverse floaters
will generally be more volatile than other tax-exempt investments. Such
securities are denoted on the Statement of Net Assets.

The Fund's may invest in advanced refunded bonds, escrow secured bonds or
defeased bonds. Under current federal tax laws and regulations, state and local
government borrowers are permitted to refinance outstanding bonds by issuing new
bonds. The issuer refinances the outstanding debt to either reduce interest
costs or to remove or alter restrictive covenants imposed by the bonds being
refinanced. A refunding transaction where the municipal securities are being
refunded within 90 days or less from the issuance of the refunding issue is
known as a "current refunding". "Advance refunded bonds" are bonds in which the
refunded bond issue remains outstanding for more than 90 days following the
issuance of the refunding issue. In an advance refunding, the issuer will use
the proceeds of a new bond issue to purchase high grade interest bearing debt
securities which are then deposited in an irrevocable escrow account held by an
escrow agent to secure all future payments of principal and interest and bond
premium of the advance refunded bond. Bonds are "escrowed to maturity" when the
proceeds of the refunding issue are deposited in an escrow account for
investment sufficient to pay all of the principal and interest on the original
interest payment and maturity dates. Bonds are considered "pre-refunded" when
the refunding issue's proceeds are escrowed only until a permitted call date or
dates on the refunded issue with the refunded issue being redeemed at the time,
including any required premium. Bonds become "defeased" when the rights and
interests of the bondholders and of their lien on the pledged revenues or other
security under the terms of the bond contract are substituted with an
alternative source of revenues (the escrow securities) sufficient to meet
payments of principal and interest to maturity or to the first call
dates. Escrowed secured bonds will often receive a rating of AAA from Moody's,
S&P, and/or Fitch due to the strong credit quality of the escrow securities and
the irrevocable nature of the escrow deposit agreement. The Tax-Free Minnesota
Insured Fund will purchase escrow secured bonds without additional insurance
only where the escrow is invested in securities of the U.S. government or
agencies or instrumentalities of the U.S. government.

Each Fund may invest a portion of its total assets in illiquid securities, which
may include securities with contractual restrictions on resale, securities
exempt from registration under Rule 144A of the Securities Act of 1933, as
amended, and other securities which may not be readily marketable. The relative
illiquidity of these securities may impair each Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so.
At August 31, 2005, there were no Rule 144A securities and no securities have
been determined to be illiquid under the Fund's Liquidity Procedures. While
maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day
functions of determining whether individual securities are liquid for purposes
of the Funds' limitation on investments in illiquid assets.

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

9. TAX INFORMATION (UNAUDITED)
The information set forth below is for each Fund's fiscal year as required by
federal laws. Shareholders, however, must report distributions on a calendar
year basis for income tax purposes, which may include distributions for portions
of two fiscal years of a Fund. Accordingly, the information needed by
shareholders for income tax purposes will be sent to them in January of each
year. Please consult your tax advisor for proper treatment of this information.

For the fiscal year ended August 31, 2005, each Fund designates distributions
paid during the year as follows:

REPORT
   OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees
Voyageur Tax Free Funds - Delaware Tax-Free Minnesota Fund
Voyageur Insured Funds - Delaware Tax-Free Minnesota
Insured Fund
Voyageur Intermediate Tax Free Funds - Delaware Tax-Free
Minnesota Intermediate Fund
Voyageur Mutual Funds - Delaware Minnesota High-Yield
Municipal Bond Fund

We have audited the accompanying statements of net assets of Voyageur Tax Free
Funds (comprised of Delaware Tax-Free Minnesota Fund), Delaware Tax-Free
Minnesota Insured Fund (one of the series constituting Voyageur Insured Funds),
Voyageur Intermediate Tax Free Funds (comprised of Delaware Tax-Free Minnesota
Intermediate Fund) and Delaware Minnesota High-Yield Municipal Bond Fund (one of
the series constituting Voyageur Mutual Funds) (the "Funds") as of August 31,
2005, and the related statements of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' control over financial reporting. Accordingly, we
express no such opinion. An audit also includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements and
financial highlights, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement
presentation. Our audit procedures included confirmation of securities owned as
of August 31, 2005, by correspondence with the custodian and brokers or by other
appropriate auditing procedures where replies from brokers were not received.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Delaware Tax-Free Minnesota Fund of Voyageur Tax Free Funds, the Delaware
Tax-Free Minnesota Insured Fund of Voyageur Insured Funds, the Delaware Tax-Free
Minnesota Intermediate Fund of Voyageur Intermediate Tax Free Funds, and the
Delaware Minnesota High-Yield Municipal Bond Fund of Voyageur Mutual Funds at
August 31, 2005, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then ended,
and their financial highlights for each of the five years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION OF DELAWARE MINNESOTA MUNICIPAL BOND FUNDS INVESTMENT
ADVISORY AGREEMENT
At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Boards of
Trustees, including a majority of disinterested or independent Trustees,
approved the renewal of the Investment Advisory Agreements for the Delaware
Minnesota High-Yield Municipal Bond Fund, Delaware Tax-Free Minnesota Fund,
Delaware Tax-Free Minnesota Insured Fund and Delaware Tax-Free Minnesota
Intermediate Fund (each a "Fund" and together the "Funds"). In making its
decision, the Board considered information furnished throughout the year at
regular Board meetings, as well as information prepared specifically in
connection with the Annual Meeting. Information furnished and discussed
throughout the year included reports detailing Fund performance, investment
strategies, expenses, compliance matters and other services provided by Delaware
Management Company ("DMC"), the investment advisor. Information furnished
specifically in connection with the Annual Meeting included materials provided
by DMC and its affiliates ("Delaware Investments") concerning, among other
things, the level of services provided to the Funds, the costs of such services
to the Funds, economies of scale and the financial condition and profitability
of Delaware Investments. In addition, in connection with the Annual Meeting, the
Board separately received and reviewed independent historical and comparative
reports prepared by Lipper Inc. ("Lipper"), an independent

ADVISORY AGREEMENT (CONTINUED)
statistical compilation organization. The Lipper reports compared each Fund's
investment performance and expenses with those of other comparable mutual funds.
The Board also requested and received certain supplemental information regarding
management's policy with respect to advisory fee levels and its philosophy with
respect to breakpoints; the structure of portfolio manager compensation; the
investment manager's profitability organized by client type, including the
Funds; and any constraints or limitations on the availability of securities in
certain investment styles which might inhibit the advisor's ability to fully
invest in accordance with each Fund's policies.

In considering such materials, the independent Trustees received assistance and
advice from and met separately with independent counsel and representatives from
Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman
of the Delaware Investments Family of Funds, and Chairman and Chief Executive
Officer of the investment advisor, was present to respond to questions raised by
Lipper and the independent Trustees. While the Board considered the Investment
Advisory Agreements for all of the funds in the Delaware Investments Family of
Funds at the same Board meeting, information was provided and considered by the
Board for each fund individually. In approving the continuance of the Investment
Advisory Agreements for the Funds, the Board, including a majority of
independent Trustees, determined that the existing advisory fee structure was
fair and reasonable and that the continuance of the Investment Advisory
Agreements was in the best interests of the Funds and their shareholders. While
attention was given to all information furnished, the following discusses the
primary factors relevant to the Board's deliberations and determination,
including those relating to the selection of the investment advisor and the
approval of the advisory fee.

NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services
provided by Delaware Investments to the Funds and their shareholders. In
reviewing the nature, extent and quality of services, the Board emphasized
reports furnished to it throughout the year at regular Board meetings covering
matters such as the compliance of portfolio managers with the investment
policies, strategies and restrictions for the Funds, the compliance of
management personnel with the Code of Ethics adopted throughout the Delaware
Investments Family of Funds complex, the adherence to fair value pricing
procedures as established by the Board, and the accuracy of net asset value
calculations. The Board noted that it was pleased with the current staffing of
the Funds' investment advisor during the past year, the emphasis on research and
the compensation system for advisory personnel. Favorable consideration was
given to DMC's efforts to maintain, and in some instances increase, financial
and human resources committed to fund matters. Other factors taken into account
by the Board were Delaware Investments' preparedness for, and response to, legal
and regulatory matters. The Board also considered the transfer agent and
shareholder services provided to Fund shareholders by Delaware Investments'
affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate
of the DALBAR Pyramid Award in four of the last six years and the continuing
expenditures by Delaware Investments to increase and improve the scope of
shareholder services. Additionally, the Board noted the extent of benefits
provided to Fund shareholders for being part of the Delaware Investments Family
of Funds, including the privilege to exchange investments between the same class
of funds without a sales charge, the ability to reinvest Fund dividends into
other funds and the privilege to combine holdings in other funds to obtain a
reduced sales charge. The Board was satisfied with the nature, extent and
quality of the overall services provided by Delaware Investments.

INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC
and the Funds. The Board was pleased by DMC's investment performance, noting
Barron's ranking of the Delaware Investments Family of Funds in the top quartile
of mutual fund families for 2002 - 2004. The Board placed significant emphasis
on the investment performance of the Funds in view of its importance to
shareholders. While consideration was given to performance reports and
discussions with portfolio managers at Board meetings throughout the year,
particular attention in assessing performance was given to the Lipper reports
furnished for the Annual Meeting. The Lipper reports prepared for each Fund
showed the investment performance of its Class A shares in comparison to a group
of similar funds as selected by Lipper (the "Performance Universe"). A fund with
the highest performance is ranked first, and a fund with the lowest is ranked
last. The highest/best performing 25% of funds in the Performance Universe make
up the first quartile; the next 25% - the second quartile; the next 25% - the
third quartile; and the lowest/worst performing 25% of funds in the Performance
Universe make up the fourth quartile. Comparative annualized performance for the
Funds was shown for the past one, three, five and 10 year periods, as
applicable, ended February 28, 2005. The Board noted its objective that each
Fund's performance be at or above the median of its Performance Universe. The
following paragraphs summarize the performance results for the Funds and the
Board's view of such performance.

DELAWARE TAX-FREE MINNESOTA INSURED FUND -- The Performance Universe for this
Fund consisted of the Fund and all retail and institutional Minnesota municipal
debt funds as selected by Lipper. The Lipper report comparison showed that the
Fund's total return for the one, five and 10 year periods was in the second
quartile of such Performance Universe. The report further showed that the Fund's
total return for the three year period was in the first quartile. The Board was
satisfied with such performance.

   FUND INFORMATION (CONTINUED)

ADVISORY AGREEMENT (CONTINUED)
COMPARATIVE EXPENSES. The Board considered expense comparison data for the
Delaware Investments Family of Funds, Delaware Investments' institutional
separate account business and other lines of business at Delaware Investments.
The Board stated its belief that, given the differing level of service provided
to Delaware Investments' various clients and other factors that related to the
establishment of fee levels, variations in the levels of fees and expenses were
justified. The Board placed significant emphasis on the comparative analysis of
the management fees and total expense ratios of each Fund compared with those of
a group of similar funds as selected by Lipper (the "Expense Group") and among
the other Delaware Investments funds. In reviewing comparative costs, each
Fund's contractual management fee and the actual management fee incurred by the
Fund were compared with the contractual management fees (assuming all funds in
the Expense Group were similar in size to the Fund) and actual management fees
(as reported by each fund) of other funds within the Expense Group, taking into
effect any applicable breakpoints and fee waivers. Each Fund's total expenses
were also compared with those of its Expense Group. The Lipper total expenses,
for comparative consistency, were shown by Lipper for Class A shares and
compared total expenses including 12b-1 and non-12b-1 service fees. The Board
noted its objective to limit each Fund's total expense ratio to an acceptable
range as compared to the median of the Expense Group. The following paragraphs
summarize the expense results for the Funds and the Board's view of such
expenses.

DELAWARE TAX-FREE MINNESOTA INSURED FUND -- The expense comparisons for the Fund
showed that its management fee and total expenses were in the quartile with the
second highest expenses of its Expense Group. The Board noted that the Fund's
total expenses were not in line with the Board's objective. In evaluating the
total expenses, the Board considered waivers in place through October 2005. The
Board was satisfied with management's efforts to improve the Fund's total
expense ratio and bring it in line with the Board's objective.

MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any,
realized by Delaware Investments in connection with the operation of the Funds.
In this respect, the Board reviewed the Investment Management Profitability
Analysis that addressed the overall profitability of Delaware Investments'
business in providing management and other services to each of the individual
funds and the Delaware Investments Family of Funds as a whole. Specific
attention was given to the methodology followed in allocating costs for the
purpose of determining profitability. Management stated that the level of
profits of Delaware Investments, to a certain extent, reflected operational cost
savings and efficiencies initiated by Delaware Investments. The Board considered
Delaware Investments' expenditures to improve services provided to fund
shareholders and to meet additional regulatory and compliance requirements
resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also
considered the extent to which Delaware Investments might derive ancillary
benefits from fund operations, including the potential for procuring additional
business as a result of the prestige and visibility associated with its role as
service provider to the Delaware Investments Family of Funds, the benefits from
allocation of fund brokerage to improve trading efficiencies and the use of
"soft" commission dollars to pay for proprietary and non-proprietary research.
At the Board's request, management also provided information relating to
Delaware Investments' profitability by client type. The information provided set
forth the revenue, expenses and pre-tax income/loss attributable to the Delaware
Investments Family of Funds, Delaware Investments' separate account business and
other lines of business at Delaware Investments. Emphasis was given to the level
and type of service provided to the various clients. The Board was satisfied
with the level of profits realized by Delaware Investments from its
relationships with the Funds and the Delaware Investments Family of Funds.

ECONOMIES OF SCALE. The Trustees considered whether economies of scale are
realized by Delaware Investments as each Fund's assets increase and the extent
to which any economies of scale are reflected in the level of management fees
charged. The Trustees took into account the standardized advisory fee pricing
and structure approved by the Board and shareholders as part of a complex-wide
shareholder meeting conducted in 1998/1999. At that time, Delaware Investments
introduced breakpoints to account for management economies of scale. The Board
noted that the fee under each Fund's management contract fell within the
standard structure. Although the Funds have not reached a size at which they can
take advantage of breakpoints, the Board recognized that the fee was structured
so that when the Funds grow, economies of scale may be shared.

DELAWARE INVESTMENTS(R) FAMILY OF FUNDS
       BOARD OF TRUSTEES/DIRECTORS AND OFFICERS ADDENDUM

A mutual fund is governed by a Board of Trustees/Directors ("Trustees"), which
has oversight responsibility for the management of a fund's business affairs.
Trustees establish procedures and oversee and review the performance of the
investment manager, the distributor and others that perform services for the
fund. The independent fund trustees, in particular, are advocates for
shareholder interests. The following is a list of the Trustees and Officers with
certain background and related information.
