Portfolio management review


Delaware National Tax-Free Funds

August 31, 2006


Joseph R. Baxter

Robert Collins

Co-managers of the funds

The managers of Delaware Tax-Free USA Fund, Delaware Tax-Free USA Intermediate
Fund, and Delaware National High-Yield Municipal Bond Fund provided the answers
to the questions below as a review of the Funds' activities for the fiscal year
ended August 31, 2006.

Q: What was the investment environment for the Delaware Investments municipal
bond mutual funds during the fiscal year ended August 31, 2006?

A: Higher gasoline prices, rising short-term interest rates, and ongoing
uneasiness about changes in the housing market generally weighed on the capital
markets and many investors' outlook for the U.S. economy during our fiscal year.
However, the U.S. economy continued its expansion throughout the year,
recovering somewhat from a period of slower growth that occurred just after the
August and September 2005 hurricanes. Property and casualty insurers held steady
and provided a solid source of capital for the tax-exempt debt arena as the year
progressed. To summarize, we generally viewed the national-level municipal bond
market to be sound over the fiscal year, despite challenges.

During most of the fiscal year, the U.S. Federal Reserve (Fed) continued to
raise interest rates. After gradually moving the target for the fed funds rate
from 3.50% to 5.25%, the Fed finally paused a long string of increases at its
August 2006 meeting. A key tool in the Fed's monetary policy, the Fed funds rate
reflects the percentage of interest that banks charge to lend money to each
other overnight. Through the rate increases, the Fed aimed to moderate the pace
of economic activity and head off inflation.

Earlier in 2006, the interest rate environment was such that the Treasury yield
curve began to flatten, which means that the difference between short- and
long-term bond yields grew smaller across the spectrum of maturities. This
"flattening" was generally present throughout the second half of the fiscal
year. In this type of situation, bonds with intermediate maturities - those in
the three- to seven-year range - tend to underperform.

Low interest rates provided many issuers with refinancing opportunities early in
the fiscal year, but new bond issuance dropped off significantly beginning in
2006 because more and more municipal issuers had already taken the opportunity
to refinance bonds. For instance, through August 2006, the pace of new issuance
of municipal securities year-to-date had retreated 15% versus the same period
one year earlier (source: Thomson Financial).

Comparing tax-exempt and taxable holdings, municipal bond yields began the
fiscal year at nearly the same level as Treasuries. By period end, however, that
gap had widened, which reflected the greater decline in the value of Treasury
bonds versus their municipal peers (source: Thomson Financial).

Q: What other market-related events influenced performance of the funds?

A: Credit quality among bond issuers remained strong or improved during the
fiscal year, generally contributing to demand for lower-rated securities.

In the fiscal period's later stages, we saw more bonds coming to market that we
believed to be of increased risk. Also of note, non-traditional buyers (those
more interested in the relative valuation of the asset class than the
tax-advantaged status of municipal bonds) continued to make their presence felt.
These changes influenced trading patterns in the market and presented a new
challenge to both mutual fund managers and individual investors.

Q: How did the market environment affect your approach to municipal bond
investing at large?

A: In the interest rate environment that prevailed, our approach to municipal
bond markets at times dictated that we retain current holdings and ultimately
our strategy resulted in limited transactions. During much of the year, we
preferred to seek that objective by holding legacy bonds - securities purchased
in prior fiscal periods - and relying on the attractive bond yields that already
existed within our portfolio of investments.


                                                                               1





Portfolio management review


Generally speaking, it became increasingly difficult in the prevailing interest
rate environment to identify bonds in the market that were more attractive than
the holdings in our portfolio. Frequently during the year, we opted to focus our
resources on monitoring the credit of legacy bonds.

We also adhered to our bottom-up investment style, which is based on
security-by-security analysis and a free exchange of information among the
various members of a deep team that includes portfolio managers, credit
analysts, and traders.

Delaware Tax-Free USA Fund

Q: How did the Fund perform versus its benchmark index and peer group?

A: Delaware Tax-Free USA Fund returned 2.42% at net asset value and -2.16% at
maximum offer price (both figures represent Class A shares with distributions
reinvested) for the fiscal year ended August 31, 2006. The Fund's performance
benchmark, the Lehman Brothers Municipal Bond Index, returned 2.56%. Its peer
group - as measured by the Lipper General Municipal Funds Average - returned
2.70% (source: Lipper). For the complete, annualized performance of Delaware
Tax-Free USA Fund, please see the table on page 6.

Q: What strategies affected Fund performance?

A: Despite a high level of refinancing activity in the market, we believed that
many of the Delaware Tax-Free USA Fund legacy bonds would not be called, and
decided to hold them for their relatively attractive yields.

In keeping with our long-term commitment to holding a high-quality portfolio of
investments, we again generally avoided the tobacco industry bonds that have so
greatly influenced performance in the municipal market in recent years, as we
believe the sector has an elevated risk for litigation. We also remained
underweighted versus the benchmark index in bonds backed by airline corporation
revenues, although a small number of airline and airline-related holdings did
influence performance in the Fund.

During the 12-month span, it seemed that investors tended to seek the added
yield and total return potential of lower-quality bonds, and thus securities
with ratings further down the credit spectrum generally outperformed. At times,
the margin of outperformance between two adjacent credit ratings was
significant.

As the fiscal year began, we employed a barbell portfolio strategy, which favors
short- and long-term maturity bonds over their intermediate term peers. We did
so because it appeared likely that further flattening of the yield curve was in
store. In 2006, we added more mid-maturity securities to the portfolio. Although
the Fund was still generally oriented for further yield curve flattening, we
believed that this move would give us better positioning should yields rise.

We also incorporated the assets of three other Delaware Investments municipal
bond funds (Delaware Tax-Free Insured Fund, Delaware Tax-Free Oregon Insured
Fund, and Delaware Tax-Free Missouri Insured Fund) into the Fund during the
year. With the merger of these assets into the investment portfolio, our
exposure to very high-quality securities rose. Because trimming the higher rated
securities took some time, we believe Fund total return performance in the
interim was slightly lower than it would have been otherwise.

The Fund gained performance relative to its benchmark index with air cargo
bonds, which constituted three of the five top performing securities. On the
other hand, exposure to Michigan's Midland Cogeneration Venture impeded return,
as did debt holdings in Northwest Air, which filed for Chapter 11 bankruptcy
protection during the 12-month period. As for sector representation within the
Fund portfolio, healthcare bonds, largely hospitals, came in first at 17% of net
assets at fiscal year end.

Delaware Tax-Free USA Intermediate Fund

Q: How did the Fund perform versus its benchmark index and peer group?

A: Delaware Tax-Free USA Intermediate Fund returned 2.38% at net asset value and
- -0.45% at maximum offer price (both figures represent Class A shares with


2





distributions reinvested) for the fiscal year ended August 31, 2006.

As of August 31, 2006, the Delaware Tax-Free USA Intermediate Fund benchmark
index was changed from the Merrill Lynch 3-7 Year Municipal Bond Index to the
Lehman Brothers Municipal 3-15 Year Index. Management believes the new benchmark
index more accurately reflects the portion of the municipal market in which the
Fund invests. There were no material changes to the Fund's investment objective
or strategy.

For the year fiscal year ended August 31, 2006, the Merrill Lynch 3-7 Year
Municipal Bond Index gained 2.38% and the Lehman Brothers 3-15 Year Municipal
Bond Index gained 2.64%. The Fund's peer group - as measured by the Lipper Other
States Intermediate Municipal Debt Funds Average - returned 3.01% (source:
Lipper).

For the complete, annualized performance of Delaware Tax-Free USA Intermediate
Fund, please see the table on page 8.

Q: What strategies affected Fund performance?

A: Despite a high level of refinancing activity in the market, we believed that
many of the Fund's legacy bonds would not be called, and decided to hold them
for their relatively attractive yields.

This strategy had the effect of shortening the Fund's average duration, which is
a measure of a bond or a bond fund's sensitivity to changes in interest rates.
Longer durations typically indicate greater interest rate sensitivity, and
shorter durations generally limit a bond fund's volatility and total return
potential.

In keeping with our long-term commitment to holding a high-quality portfolio of
investments, we again generally avoided the tobacco industry bonds that have so
greatly influenced performance in the municipal market in recent years, as we
believe the sector has an elevated risk for litigation. We also remained
underweighted versus the benchmark index in bonds backed by airline corporation
revenues. Neither stance was generally beneficial when comparing Fund
performance to the benchmark and many of our peer funds because those two
sectors performed well on a total return basis.

During the 12-month span, it seemed that investors tended to seek the added
yield and total return potential of lower-quality bonds, and thus securities
with ratings further down the credit spectrum generally outperformed. At times,
the margin of outperformance between two adjacent credit ratings was
significant.

As the fiscal year began, we employed a barbell portfolio strategy, which favors
short- and long maturity bonds over their intermediate term peers. We did so
because it appeared likely that further flattening of the yield curve was in
store. In 2006, we added more mid-maturity securities to the portfolio. Although
the fund was still generally oriented for further yield curve flattening, we
believed that this move would give us better positioning should yields rise.

In reviewing performance attribution, we added positively to portfolio return
with our acquisition of continued care and retirement center bonds, which also
accounted for the portfolio's increased exposure to non-rated securities. Fund
return was enhanced by New York City general obligation bonds and air cargo
securities. The calling of some of our bonds (retired by their issuer prior to
maturity) caused the portfolio to lose a measure of return during the period.
The same may be said of municipal securities issued by Puerto Rico, which
experienced budgetary concerns during the period.

In other adjustments, we trimmed the Fund portfolio's exposure to insured bonds
from 40% to roughly 25% of net assets. We maintained the portfolio's high credit
quality by opting for state general obligation bonds, which constituted 17% of
net assets upon fiscal year end.

Delaware National High-Yield Municipal Bond Fund

Q: How did the Fund perform versus its benchmark index and peer group?

A: Delaware National High-Yield Municipal Bond Fund returned 4.15% at net asset
value and -0.54% at maximum offer price (both figures represent Class A


                                                                               3

shares with distributions reinvested) for the fiscal year ended August 31, 2006.
For the same period, the Lehman Brothers Municipal Bond Index returned 2.56% and
the Fund's peer group - as measured by the Lipper High-Yield Municipal Debt
Funds Average - returned 5.12% (source: Lipper).

For the complete, annualized performance of Delaware National High-Yield
Municipal Bond Fund, please see the table on page 10.

Q: What strategies affected Fund performance?

A: Despite a high level of refinancing activity in the market, we believed that
many of the Fund's legacy bonds would not be called, and decided to hold them
for their relatively attractive yields.

This strategy had the effect of shortening the Fund's average duration, which is
a measure of a bond or a bond fund's sensitivity to changes in interest rates.
Longer durations indicate greater interest rate sensitivity, and shorter
durations generally limit a bond fund's volatility and total return potential.
The Fund's duration profile at fiscal year end was near the lower end of our
target range, a consideration that we monitored.

In keeping with our long-term commitment to holding a high-quality portfolio of
investments, we again generally avoided the tobacco industry bonds that have so
greatly influenced performance in the municipal market in recent years, as we
believe the sector has an elevated risk for litigation. We also remained
underweighted versus the benchmark index in bonds backed by airline corporation
revenues, although a small number of airline and airline-related holdings did
influence performance in the Fund.

During the 12-month span, it seemed that investors tended to seek the added
yield and total return potential of lower-quality bonds. Thus, securities with
ratings further down the credit spectrum generally outperformed. At times, the
margin of outperformance between two adjacent credit ratings was significant.

Over the course of the fiscal year, we trimmed the portfolio's allocation to
bonds rated BBB and increased exposure to tax increment financing bonds (TIFs).
Used principally with redevelopment projects, TIFs proved to be valuable sources
of income and accounted for our increased exposure to non-rated securities. We
also found that continuing care retirement center bonds were beneficial to Fund
performance.

Conversely, our exposure to a Northwest Airlines, which filed for Chapter 11
bankruptcy protection, impeded Fund return. In addition, the rise in natural gas
prices during the period worked against our position in Michigan's Midland
Cogeneration Venture bonds. These bonds were no longer held in the Fund at the
end of August 2006.

The Merrill Lynch 3-7 Year Municipal Bond Index is an unmanaged index that
generally tracks the performance of municipal bonds with maturities of 3 to 7
years. The Lehman Brothers 3-15 Year Municipal Bond Index is an unmanaged index
that generally tracks the performance of municipal bonds with maturities of 3 to
15 years. 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.

Past performance is not a guarantee of future results.

Performance summary


Delaware National High-Yield Municipal Bond Fund


The performance data quoted represent past performance; past performance does
not guarantee future results. A rise or fall in 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. 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 www.delawareinvestments.com/performance.

You should consider the investment objectives, risks, charges, and expenses of
the investment carefully before investing. The Delaware National High-Yield
Municipal Bond Fund prospectus contains this and other important information
about the Fund. Please request a prospectus through your financial advisor or by
calling 800 523-1918 or visiting our Web site. Read it carefully before you
invest or send money.

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 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 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 National
High-Yield Municipal Bond Fund during the periods shown above and on the next
page. Performance would have been lower had the expense limitation not been in
effect.

The performance table above and the graph on the next page do 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 of Fund expenses


For the period March 1, 2006 to August 31, 2006


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, 2006 to August 31, 2006.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

Please note that the expenses shown in the 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. The Funds' actual expenses shown in the tables reflect fee waivers in
effect. The expenses shown in each table assume reinvestment of all dividends
and distributions.

In each case, "Expenses Paid During Period" are equal to the Fund's annualized
expense ratio, multiplied by the average account value over the period,
multiplied by 184/365 (to reflect the one-half year period).

Notes to financial statements


Delaware National Tax-Free Funds

August 31, 2006


Delaware Group Tax-Free Fund is organized as a Delaware statutory trust and
offers two series: Delaware Tax-Free USA Fund and Delaware Tax-Free USA
Intermediate Fund. Voyageur Mutual Funds is organized as a Delaware statutory
trust and offers five series: Delaware Tax-Free California Fund, Delaware
Tax-Free Idaho Fund, Delaware Minnesota High-Yield Municipal Bond Fund, Delaware
National High-Yield Municipal Bond Fund and Delaware Tax-Free New York Fund.
Delaware Group Tax-Free Fund and Voyageur Mutual Funds are individually referred
to as a "Trust" and collectively as the "Trusts". These financial statements and
the related notes pertain to Delaware Tax-Free USA Fund, Delaware Tax-Free USA
Intermediate Fund and Delaware National High-Yield Municipal Bond Fund (each
referred to as a "Fund" or, collectively, as 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% for Delaware Tax-Free USA Fund and Delaware National High-Yield
Municipal Bond Fund, and up to 2.75% for Delaware Tax-Free USA Intermediate
Fund. Class A share purchases of $1,000,000 or more will incur a contingent
deferred sales charge of up to 1% if redeemed during the first two years,
provided that a financial advisor was paid commission on the purchase of those
shares. Class B shares of the Delaware Tax-Free USA Fund and Delaware National
High-Yield Municipal Bond Fund are sold with a contingent deferred sales charge
that declines from 4% to zero depending upon the period of time the shares are
held and will automatically convert to Class A shares on a quarterly basis
approximately eight years after purchase. Class B shares of Delaware Tax-Free
USA Intermediate Fund are sold with a contingent deferred sales charge that
declines from 2% to zero depending upon the time the shares are held and will
automatically convert to Class A shares on a quarterly basis approximately five
years after purchase. Class C shares are sold with a contingent deferred sales
charge of 1%, if redeemed during the first twelve months.

The investment objective of Delaware Tax-Free USA Fund and Delaware Tax-Free USA
Intermediate Fund is to seek as high a level of current interest income exempt
from federal income tax as is available from municipal obligations as is
consistent with prudent investment management and preservation of capital.

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

1. Significant Accounting Policies

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

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

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

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented, and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006 and is to be applied
to all open tax years as of the effective date. Although the Fund's tax
positions are currently being evaluated, management does not expect the adoption
of FIN 48 to have a material impact on each Fund's financial statements.

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

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

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

1. Significant Accounting Policies (continued)

The Funds receive earnings credits from their custodian when positive cash
balances are maintained, which are used to offset custody fees. The expense paid
under the above arrangement is included in custodian fees on the Statements of
Operations with the corresponding expense offset shown as "expense paid
indirectly."

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

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. Each Fund pays
DSC a monthly fee computed at the annual rate of 0.04% of such Fund's average
daily net assets for accounting and administration services. Each Fund pays DSC
a monthly fee based on the number of shareholder accounts for dividend
disbursing and transfer agent services.

Pursuant to a distribution agreement and distribution plan, each Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.30% of the average daily net
assets of the Class A shares for Delaware Tax-Free USA Fund and Delaware
Tax-Free USA Intermediate Fund, 0.25% of the average daily net assets of the
Class A shares for the Delaware National High-Yield Municipal Bond Fund and
1.00% of the average daily net assets of the Class B and C shares for all Funds.
The Board of Trustees has adopted a formula for calculating 12b-1 plan fees for
Delaware Tax-Free USA Fund's Class A shares that went into effect on June 1,
1992. The total 12b-1 fees to be paid by Class A shareholders of each Fund will
be the sum of 0.10% of the average daily net assets representing shares that
were acquired prior to June 1, 1992 and 0.30%, waived to 0.25%, of the average
daily net assets representing shares that were acquired on or after June 1,
1992. The contractual 12b-1 fee waiver of 0.25% of average daily net assets is
applied to the shares of each Fund that were acquired on or after June 1, 1992
in calculating the applicable 12b-1 fee rate. All Class A shareholders will bear
12b-1 fees at the same rate, the blended rate based upon the allocation of the
rates described above. DDLP has contracted to waive distribution and service
fees through December 31, 2006 in order to prevent distribution and service fees
of Class A from exceeding 0.25% of the average daily net assets for the Delaware
Tax-Free USA Fund and 0.15% of the average daily net assets for the Delaware
Tax-Free USA Intermediate Fund.

At August 31, 2006, the Funds had liabilities payable to affiliates as follows:

The differences between book basis and tax basis components of net assets are
primarily attributable to tax deferral of losses on wash sales and tax treatment
of market discount on debt instruments.

Post-October losses represent losses realized on investment transactions from
November 1, 2005 through August 31, 2006 that, in accordance with federal income
tax regulations, the Funds have elected to defer and treat as having arisen in
the following fiscal year.

For financial reporting purposes, capital accounts are adjusted to reflect the
tax character of permanent book/tax differences. Reclassifications are primarily
due to tax treatment of market discount on certain debt instruments. Results of
operations and net assets were not affected by these reclassifications. For the
year ended August 31, 2006, the Funds recorded the following reclassifications:

6. Fund Merger

Effective July 17, 2006, Delaware Tax-Free USA Fund (the "Acquiring Fund")
acquired all of the assets and assumed all of the liabilities of Delaware
Tax-Free Oregon Insured Fund, Delaware Tax-Free Missouri Insured Fund and
Delaware Tax-Free USA Insured Fund (each an "Acquired Fund"), each an open-end
investment company, in exchange for shares of the Acquiring Fund pursuant to
Plans and Agreements of Reorganization (the "Reorganizations"). The shareholders
of each Acquired Fund received shares of the respective class of the Acquiring
Fund equal to the aggregate net asset value of their shares in the Acquired Fund
prior to the Reorganizations.

The Reorganizations were treated as non-taxable events and, accordingly,
Delaware Tax-Free USA 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 Tax-Free
Oregon Insured Fund, Delaware Tax-Free Missouri Insured Fund and Delaware
Tax-Free USA Insured Fund as of the close of business on July 14, 2006, were as
follows:

merger were $703,721,964.

7. Line of Credit

Each Fund, along with certain other funds in the Delaware Investments(R)
Family of Funds (the "Participants"), participates in a $225,000,000 revolving
line of credit facility to be used for temporary or emergency purposes as an
additional source of liquidity to fund redemptions of investor shares. The
Participants are charged an annual commitment fee, which is allocated across the
Participants on the basis of each Participant'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, 2006 or at any time during the year then ended.

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.

Delaware National High-Yield Municipal Bond Fund invests a portion of its assets
in high yield fixed income securities, which carry ratings of BB or lower by
Standard & Poor's Ratings Group and/or Ba or lower by Moody's Investors Service,
Inc. Investments in these higher yielding securities are generally accompanied
by a greater degree of credit risk than higher rated securities. Additionally,
lower rated securities may be more susceptible to adverse economic and
competitive industry conditions than investment grade securities.

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

The Fund may invest in advanced refunded bonds, escrow secured bonds or defeased
bonds. Under current federal tax laws and regulations, state and local
government borrowers are permitted to refinance outstanding bonds by issuing new
bonds. The issuer refinances the outstanding debt to either reduce interest
costs or to remove or alter restrictive covenants imposed by the bonds being
refinanced. A refunding transaction where the municipal securities are being
refunded within 90 days from the issuance of the refunding issue is known as a
"current refunding". "Advance refunded bonds" are bonds in which the refunded
bond issue remains outstanding for more than 90 days following the issuance of
the refunding issue. In an advance refunding, the issuer will use the proceeds
of a new bond issue to purchase high grade interest bearing debt securities
which are then deposited in an irrevocable escrow account held by an escrow
agent to secure all future payments of principal and interest and bond premium
of the advance refunded bond. Bonds are "escrowed to maturity" when the proceeds
of the refunding issue are deposited in an escrow account for investment
sufficient to pay all of the principal and interest on the original interest
payment and maturity dates.

                                                              (continues)     51




Notes to financial statements


Delaware National Tax-Free Funds



8. Credit and Market Risk (continued)

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 and 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 Ratings due to the strong credit quality of
the escrow securities and the irrevocable nature of the escrow deposit
agreement.

Each Fund may invest a portion of its total assets in illiquid securities, which
may include securities with contractual restrictions on resale, securities
exempt from registration under Rule 144A of the Securities Act of 1933, as
amended and other securities which may not be readily marketable. The relative
illiquidity of these securities may impair each Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so.
While maintaining oversight, the Fund's Board of Trustees has delegated to DMC
the day-to-day functions of determining whether individual securities are liquid
for purposes of the Fund's limitation on investments in illiquid assets. At
August 31, 2006, there were no Rule 144A securities. Illiquid securities have
been identified on the Statements of Net Assets.

9. Contractual Obligations

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

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, 2006, each Fund designates distributions
paid during the year as follows:

Report of independent
registered public accounting firm


To the Shareholders and Board of Trustees
Delaware Group Tax-Free Fund
Voyageur Mutual Funds - Delaware National High-Yield
Municipal Bond Fund

We have audited the accompanying statements of net assets of Delaware Group
Tax-Free Fund (comprised of Delaware Tax-Free USA Fund and Delaware Tax-Free USA
Intermediate Fund) and Delaware National High-Yield Municipal Bond Fund (one of
the series constituting Voyageur Mutual Funds) (the "Funds") as of August 31,
2006, and the related statements of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2006, 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 each
of the respective series constituting the Delaware Group Tax-Free Fund and the
Delaware National High-Yield Municipal Bond Fund of Voyageur Mutual Funds at
August 31, 2006, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then ended,
and their financial highlights for each of the five years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

Board Consideration of Delaware Tax-Free USA Fund, Delaware Tax-Free USA
Intermediate, and Delaware National High-Yield Municipal Bond Fund Agreements

At a meeting held on May 17-18, 2006 (the "Annual Meeting"), the Board of
Trustees, including a majority of disinterested or independent Trustees,
approved the renewal of the Investment Advisory Agreements for the Delaware
Tax-Free USA Fund, Delaware Tax-Free USA Intermediate Fund and Delaware National
High-Yield Municipal Bond Fund (each a "Fund" and collectively 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 considered independent historical and comparative reports prepared by
Lipper Inc. ("Lipper"), an independent statistical compilation organization. The
Board also considered industry comparative information presented by
representatives from Lipper. The Lipper reports compared each Fund's investment
performance and expenses with those of other comparable mutual funds. The Board
also 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; and any
constraints or limitations on the availability of securities in certain
investment styles which might inhibit DMC's ability to fully invest in
accordance with Fund 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, Mr. Driscoll, then
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 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 Agreement for each Fund, 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 Agreement was in the best interests of the Fund and its 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 relative performance of the Funds, 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 and management's efforts to
strengthen and deepen portfolio management teams 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.
("DSC"), noting DSC's commitment to maintain a high level of service in keeping
with its past receipt of the DALBAR Pyramid Award, and the continuing
expenditures by Delaware Investments to improve the delivery 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 shares
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.

Board Consideration of Delaware Tax-Free USA Fund, Delaware Tax-Free USA
Intermediate, and Delaware National High-Yield Municipal Bond Fund Agreements
(continued)

Investment Performance. The Board considered the investment performance of DMC
and the Funds. The Board was pleased with DMC's investment performance. 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 weight 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 best
performance is ranked first, and a fund with the poorest performance 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 poorest/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 January 31, 2006. The Board noted its objective that each
Fund's performance for the periods considered be at or above the median of its
Performance Universe. The following paragraphs summarize the performance results
for each Fund and the Board's view of such performance.

Delaware Tax-Free USA Fund - The Performance Universe for the Fund consisted of
the Fund and all retail and institutional general municipal debt funds as
selected by Lipper. The Lipper report comparison showed that the Fund's total
return for the one 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 and five year periods was in the first quartile. The Board was
satisfied with such performance.

Delaware Tax-Free USA Intermediate Fund - The Performance Universe for the Fund
consisted of the Fund and all retail and institutional intermediate municipal
debt funds as selected by Lipper. The Lipper report comparison showed that the
Fund's total return for the one, three, five and 10 year periods was in the
first quartile of such Performance Universe. The Board was satisfied with such
performance.

Delaware National High-Yield Municipal Bond Fund - The Performance Universe for
the Fund consisted of the Fund and all retail and institutional high yield
municipal debt funds as selected by Lipper. The Lipper report comparison showed
that the Fund's total return for the one year period was in the third quartile
of such Performance Universe. The report further showed that the Fund's total
return for three and five year periods was in the second quartile and the Fund's
total return for the 10 year period was in the first quartile. The Board noted
that the Fund's performance results were mixed but on an overall basis tended
toward above median, which was acceptable.

Comparative Expenses. The Board considered expense data for the Delaware
Investments(R) Family of Funds. Management provided the Board with information
on pricing levels and fee structures for the Funds. The Board focused
particularly on the comparative analysis of the management fees and total
expense ratios of each Fund and the management fees and expense ratios of a
group of similar funds as selected by Lipper (the "Expense Group"). 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 also considered fees paid to Delaware
Investments for non-management services. 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 paragraph summarizes the expense results for
each Fund and the Board's view of such expenses.

Delaware Tax-Free USA Fund - The expense comparisons for the Fund showed that
its actual management fee was in the quartile with the second lowest expenses of
its Expense Group and its total expenses were in the quartile with the second
highest expenses of its Expense Group. The Board gave favorable consideration to
the Fund's management fee, but noted that the Fund's total expenses were not in
line with the Board's stated objective. In evaluating the total expenses, the
Board considered fee waivers in place through December 2006 and recent
initiatives implemented by management, such as the outsourcing of certain
transfer agency services, creating an opportunity for a reduction in expenses.
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 USA Intermediate Fund - The expense comparisons for the Fund
showed that its actual 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 National High-Yield Municipal Bond Fund - The expense comparisons for
the Fund showed that its actual management fee was in the quartile with the
lowest expenses of its Expense Group and its total expenses were in the quartile
with the second 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. 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


                                                                              55

compliance requirements resulting from 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.
The Board did not find that the level of profits realized by Delaware
Investments from the relationships with the Funds and the Delaware Investments
Family of Funds required negotiation of reduction of fees.


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. With respect to the Delaware Tax-Free USA Intermediate Fund
and Delaware National High-Yield Municipal Bond Fund, although the Funds have
not reached a size at which they can take advantage of breakpoints, the Board
recognized that the fees were structured so that when the Funds grow, economies
of scale may be shared. With respect to the Delaware Tax-Free USA Fund, the
Board also noted that the Fund's assets exceeded the first breakpoint level. The
Board believed that, given the extent to which economics of scale might be
realized by the advisor and its affiliates, the schedule of fees under the
Investment Advisory Agreement provides a sharing of benefits with the Fund and
its shareholders.

Board of trustees/directors
and officers addendum


Delaware Investments(R) Family of Funds

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 who perform services for the
fund. The independent fund trustees, in particular, are advocates for
shareholder interests. Each trustee has served in that capacity since he or she
was elected to or appointed to the Board of Trustees, and will continue to serve
until his or her retirement or the election of a new trustee in his or her
place. The following is a list of the Trustees and Officers with certain
background and related information.

connection with the accounting for estimates, accruals, and reserves;

experience actively supervising one or more persons engaged in such activities;

     d. An understanding of internal controls and procedures for financial
reporting; and

     e. An understanding of audit committee functions.
