POWERED BY RESEARCH(R)        EXPERIENCE DELAWARE INVESTMENTS

                              OUR MISSION:

                              Delaware Investments is committed to the pursuit
                              of consistently superior asset management and
                              unparalleled client service. We strongly believe
                              in our investment process, the consistent results
                              we seek to deliver, and the value we can add for
                              our clients.

                              OUR HISTORY:

                              Delaware Investments traces its roots to an
                              investment advisory firm founded in 1929. We
                              quickly learned how important consistent
                              performance was to our clients, particularly in
                              tough times, and continued to apply those lessons
                              when we launched our first mutual fund in 1938.
                              Delaware has managed money through 75 years of
                              market cycles, and our dedication to consistent
                              performance over the long term endures to this
                              day.

                              OUR PRINCIPLES:

                              CLIENTS FIRST

                              We believe that placing clients' interests ahead
                              of our own is always the right thing to do. We
                              offer a focused lineup of products that is aligned
                              with our core asset management competencies rather
                              than with popular trends. Some of the largest
                              pension plans, endowments, and foundations have
                              entrusted their investments to Delaware
                              Investments. Our institutional heritage and
                              expertise serve us well when crafting mutual funds
                              and managed account portfolios for individual
                              investors.

                              PASSION FOR PERFORMANCE

                              Our results-oriented culture puts investors first
                              and begins with our passion for performance. We
                              seek to deliver consistently superior returns over
                              the long term, and to do it in every asset class.
                              This means we look at three-year and five-year
                              track records as starting points in seeking to
                              deliver long-term outperformance.

                              PEOPLE WE'RE PROUD OF

                              We recognize that smart, accomplished people are a
                              competitive advantage. Our research analysts add
                              value to our investors' portfolios, just as our
                              award-winning operations team adds value for
                              shareholders. At Delaware Investments, we are more
                              than just committed -- we are passionate about our
                              mission. That culture of passion flows through
                              everything we do.

                              POWERED BY RESEARCH

                              Whether it's credit research on a corporate bond
                              or a company visit for a small-cap consumer growth
                              name, our deep teams of sector experts eat, sleep,
                              and breathe fundamental research. We believe that
                              fundamental research is the key to achieving
                              consistently superior returns over the long term.

                              STRENGTH IN PARTNERSHIP

                              Delaware Investments is the financial engine of

DEAR SHAREHOLDER:                                                  March 7, 2006

In the six months ended February 28, 2006, investors received mixed signals
about the direction of the U.S. economy, which for much of the period was
absorbing the effects of hurricanes Rita and Katrina. The new U.S. Federal
Reserve Chairman, Ben Bernanke, stepped in during a time of continuing
deliberations by the fed's Open Market Committee about monetary policy, as it
determines whether further increases in interest rates will be necessary to curb
inflation. On a positive note, investors have generally remained optimistic
despite the circumspect interest rate hikes. The outlook on Wall Street has
remained cautiously optimistic, while at the same time there has been a
continued interest in bond funds, as many investors seek to diversify.

Investors made municipal bonds -- with their tax-advantaged status -- a $1.9
trillion market in 2005 (source: Bloomberg). Generally speaking, municipal bonds
and other fixed income securities held up better than might be expected in a
challenging interest rate environment, although the Lehman Brothers Municipal
Bond Index returned 0.99% for the six months ended February 28, 2006 (source:
Lipper).

Also of note during the period, the U.S. Treasury on February 9, 2006 conducted
its first auction of 30-year bonds in four years. This sale of $14 billion in
30-year bonds is likely to affect longer-term municipal bond yields over time,
although the net long-term effect was still unclear by fiscal period end.

As you look ahead to the rest of 2006, I encourage you to work with your
financial advisor to consider building a portfolio that's diversified across the
major investment asset classes -- stocks, bonds, and short-term reserves --
keeping the allocations appropriate for your personal circumstances and risk
tolerance. It is our belief at Delaware Investments that a long-term perspective
is always healthy, and we remind you that municipal bonds are typically held
over the long term for their tax-free income. Like other fixed income
securities, municipal bonds can also serve to balance investments in stocks,
which are historically more volatile.

If you are interested in acquiring more information about creating a
well-diversified investment plan, speak with your advisor.

Thank you as always for entrusting your hard-earned dollars to Delaware
Investments.

Sincerely,

/s/ Jude T. Driscoll

Jude T. Driscoll

Disclosure                 For the Period September 1, 2005 to February 28, 2006
- --------------------------------------------------------------------------------
   OF FUND EXPENSES

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

The Examples are based on an investment of $1,000 invested at the beginning of
the period and held for the entire period September 1, 2005 to February 28,
2006.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), redemption fees, or exchange fees. Therefore, the second
section of each table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have been
higher. Each Fund's actual expenses shown in the tables reflect fee waivers in
effect. The expenses shown in each table assume reinvestment of all dividends
and distributions.

In each case "Expenses Paid During Period" are equal to the Fund's annualized
expense ratio, multiplied by the average account value over the period,
multiplied by 181/365 (to reflect the one-half year period).

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

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

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

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

   TO FINANCIAL STATEMENTS

Delaware Group Tax-Free Fund (the "Trust") is organized as a Delaware statutory
trust and offers three series: Delaware Tax-Free USA Fund, Delaware Tax-Free
Insured Fund, and Delaware Tax-Free USA Intermediate Fund. Voyageur Mutual Funds
(the "Trust") is organized as a Delaware statutory trust and offers six 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. These financial statements and
the related notes pertain to Delaware Tax-Free USA Fund, Delaware Tax-Free
Insured 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, Delaware Tax-Free Insured Fund and Delaware National High-Yield Municipal
Bond Fund, and up to 2.75% for Delaware Tax-Free USA Intermediate Fund. Class B
shares of the Delaware Tax-Free USA Fund, Delaware Tax-Free Insured 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, Delaware Tax-Free
Insured 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, aftermarket trading or significant events after local market
trading (e.g., government actions or pronouncements, trading volume or
volatility on markets, exchanges among dealers, or news events).

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

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

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

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

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

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:

2.    Investment Management, Administration Agreements and Other Transactions
      with Affiliates (continued)

DMC has contractually agreed to waive that portion, if any, of its management
fee and reimburse each Fund to the extent necessary to ensure that annual
operating expenses, exclusive of taxes, interest, brokerage commissions,
distribution fees, certain insurance costs and extraordinary expenses, do not
exceed specified percentages of average daily net assets through December 31,
2006 as shown below.

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

Pursuant to a distribution agreement and distribution plan, each Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.30% of the average daily net
assets of the Class A shares for Delaware Tax-Free USA Fund, Delaware Tax-Free
Insured 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 and
Delaware Tax-Free Insured 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 Delaware Tax-Free Insured Fund and 0.15% of the average
daily net assets for the Delaware Tax-Free USA Intermediate Fund.

At February 28, 2006, the Funds had liabilities payable to affiliates as
follows:

      behalf of each Fund and is reimbursed on a periodic basis. Such expenses
      include items such as printing of shareholder reports, fees for audit,
      legal and tax services, registration fees and trustees' fees.

As provided in the investment management agreement, each Fund bears the cost of
certain legal services expenses, including internal legal services provided to

4.    Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance
with federal income tax regulations, which may differ from U.S. generally
accepted accounting principles. Additionally, net short-term gains on sales of
investment securities are treated as ordinary income for federal income tax
purposes. The tax character of dividends and distributions paid during the six
months ended February 28, 2006 and the year ended August 31, 2005 was as
follows:

4.    Dividend and Distribution Information (continued)

For financial reporting purposes, capital accounts are adjusted to reflect the
tax character of permanent book/tax differences. Reclassifications are primarily
due to tax treatment of market discount and premium on certain debt instruments.
Results of operations and net assets were not affected by these
reclassifications. For the six months ended February 28, 2006, the Funds
recorded an estimate of these differences since the final tax characteristics
cannot be determined until fiscal year end.

6.    Line of Credit

The Funds, along with certain other funds in the Delaware Investment Family of
Funds (the "Participants"), participate in a $225,000,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each fund's allocation of the entire facility. The Participants may
borrow up to a maximum of one third of their net assets under the agreement. The
Funds had no amounts outstanding as of February 28, 2006 or at any time during
the six month period.

   TO FINANCIAL STATEMENTS (CONTINUED)

7.    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 denoted 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. 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 Investors
Service, Inc., Standard & Poor's Ratings Group, and/or Fitch due to the strong
credit quality of the escrow securities and the irrevocable nature of the escrow
deposit agreement. The Tax Free Insured Funds will purchase escrow secured bonds
without additional insurance only where the escrow is invested in securities of
the U.S. government or agencies or instrumentalities of the U.S. government.

Delaware Tax-Free USA Fund, Delaware Tax-Free Insured Fund and Delaware Tax-Free
Intermediate Fund may invest up to 10% of their 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. Delaware National High-Yield Municipal Bond Fund may invest up to
15% in such securities. 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 Funds'
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 February 28, 2006, there were no Rule 144A
securities. Illiquid securities have been denoted on the Statement of Net
Assets.

8.    Contractual Obligations

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