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 percentage 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 two-
and 30-year yields narrowed 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
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 two- 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. 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.

Credit has performed 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 July 2005, while the
unemployment rate decreased from 5.5% to 5.0% (source: U.S. 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 nine 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).

                                       1

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 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 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.

HOW DID THE FUNDS PERFORM DURING THE FISCAL YEAR?
For the fiscal year ended August 31, 2005, Delaware Tax-Free USA Fund returned
7.23% (Class A shares at net asset value with distributions reinvested) and
2.41% (at maximum offer price with distributions reinvested). Class A shares (at
net asset value with distributions reinvested) outperformed both the Lipper
General Municipal Debt Funds Average, which returned 4.73%, and the Lehman
Brothers Municipal Bond Index, which returned 5.31% for the 12-month period
(source: Lipper, Inc.).*

For the fiscal year ended August 31, 2005, Delaware Tax-Free Insured Fund
returned 5.73% (Class A shares at net asset value with distributions reinvested)
and 1.01% (at maximum offer price with distributions reinvested). Class A shares
(at net asset value with distributions reinvested) outperformed both the Lipper
Insured 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.).*

For the fiscal year ended August 31, 2005, Delaware Tax-Free USA Intermediate
Fund returned 5.63% (Class A shares at net asset value with distributions
reinvested) and 2.75% (at maximum offer price with distributions reinvested).
Class A shares (at net asset value with distributions reinvested) outperformed
both the Lipper Intermediate Municipal Debt Funds Average, which returned 3.70%,
and the Merrill Lynch 3-7 Year Municipal Bond Index, which returned 2.11% for
the 12-month period (source: Lipper, Inc.).*

For the fiscal year ended August 31, 2005, Delaware National High-Yield
Municipal Bond Fund returned 8.93% (Class A shares at net asset value with
distributions reinvested) and 4.04% (at maximum offer price with distributions
reinvested). Class A shares (at net asset value with distributions reinvested)
outperformed both the Lipper High Yield Municipal Debt Funds Average, which
returned 8.71%, and the Lehman Brothers Municipal Bond Index, which returned
5.31% for the 12-month period (source: Lipper, Inc.).*

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 by prospectus. The fourth factor, security selection, is the
heart of our investment process and is the primary source of our excess 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 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" 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 allotment to these higher risk credits.

 12.

                                       2

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 and the managed care industry. The
demographics provided by the baby boom generation have provided favorable
enrollment trend at colleges and universities, while a 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.

Delaware Tax-Free USA Fund has the broadest mandate of our four national funds
and has therefore been able to participate in all four sources of return. The
Fund is structured as a "barbell"; it has a meaningful allotment in mid-to-lower
investment-grade credits and this allowed it to participate in our preferred
sectors.

Delaware Tax-Free Insured Fund was positioned to benefit from the flattening of
the yield curve with a significant allocation of bonds having final maturities
20 years or longer. Legacy bonds that have short due dates or short calls offset
these positions. The Fund's insured mandate limits it from participating in the
credit spread tightening of lower rated bonds and therefore certain sectors. 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 in an attempt to gain excess
returns.

Delaware Tax-Free USA Intermediate Fund was also 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 also
took advantage of credit spread tightening with a meaningful allotment to
A-rated and BBB- rated securities, and some of the sectors that issue in those
categories. Excess returns were found in the dedicated tax sector with the bonds
issued by the state of New Jersey, which are backed by the cigarette sales tax
and in the healthcare sector, in names such as Benedictine Hospital in Duluth,
Minnesota and Elliot Hospital in New Hampshire. Higher education securities
included the Geneva College in Pennsylvania and an Illinois student housing
facility in Chicago. The Fund also owns bonds for Nichols College in
Massachusetts.

While Delaware National High-Yield Municipal Bond Fund's structure is also 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-rated 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. In addition to the above-mentioned
healthcare and higher education sectors, the continuing care retirement
community (CCRC) and tax increment financing (TIF) sectors have been strong
performers. CCRC's are retirement communities, combining on campus independent
living, assisted-living and skilled nursing facilities. TIFs are land
development deals that can be for residential, industrial or commercial use or a
combination thereof.

CAN YOU NAME SOME KEY HOLDINGS IN DELAWARE TAX-FREE USA FUND AND DELAWARE
NATIONAL HIGH-YIELD FUND?

Some securities that performed well during the fiscal year in Delaware Tax-Free
USA Fund include Benedictine Hospital in Duluth Minnesota, Cleveland Clinic in
Cuyahoga County Ohio, and Nichols College in Massachusetts. Nichols College was
upgraded to investment grade in early 2004 and its market value received the
benefit of both the higher rating and the tighter credit spreads. Also in the
Fund are the California tobacco bonds that are enhanced by a state
appropriation. This is a repeat performer from last year, as the bonds were
pre-refunded to their first call date and appreciated significantly in price. We
participated in a airline sector performance through industrial development
revenue bonds (IDRs) -- tax-exempt securities that are backed by corporate
revenues. We held bonds backed by Delta, American, Northwestern, and Continental
Airlines, although we currently hold only the American and Northwest bonds.

In the Delaware National High-Yield Municipal Bond Fund, securities held include
such hospitals as St. Francis in Shakopee Minnesota, Jordan Hospital in
Massachusetts, and Yavapai Regional Medical Center in Arizona. Also contributing
were a TIF deal in Midtown Miami, a CCRC in Gainesville Georgia and a
multifamily housing project in Rochester Minnesota. Also among the top returning
securities were Continental and Northwest Airlines IDRs, but the latter is the
only position we currently hold.


                                       3

WHAT DETRACTED FROM FUND PERFORMANCE?
Detracting from our Funds' performance relative to the benchmark was the
decision to avoid the unenhanced tobacco sector. This has been the best
performing sector in the municipal bond market over the past year. The master
settlement agreement between the major tobacco companies and 46 states secures
these bonds. However, the sector is subject to litigation risk. We are
comfortable foregoing this potential source of volatility in the Funds.

Airline securities significantly outperformed the municipal market this year
during the second quarter, which is a traditional busy season. We underperformed
when we did participate in this sector, due to an underweight, as we are
concerned about the long-term fundamentals of the industry. We did hold the
aforementioned positions in several funds, but were underweight versus the
benchmark and our peers.

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. Our decision to hold underperforming
bonds, too, detracted from performance.

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.

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 0.30%.

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%.

Performance reflects certain expense limitations in effect for 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.

Chart assumes $10,000 invested on August 31, 1995 and includes the effect of a
4.50% front-end sales charge and the reinvestment of all distributions.
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.
An expense limit was in effect beginning August 1, 2001. Performance would have
been lower had the expense limit not been in effect. The performance graph does
not reflect the deduction of taxes the shareholder would pay on Fund
distributions or redemptions of Fund shares. Past performance is not a guarantee
of future results.

PERFORMANCE SUMMARY
   DELAWARE TAX-FREE 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 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 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 0.30%.

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%.

Performance reflects certain expense limitations in effect for 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 Fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Fund's actual return. The hypothetical account
values and expenses may not be used to estimate the actual ending account
balance or expenses you paid for the period. You may use this information to
compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

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

(1)  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.

(2)  As required, effective September 1, 2001, the Fund adopted the provisions
     of the AICPA Audit and Accounting Guide for Investment Companies that
     requires 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

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

(2)  As required, effective September 1, 2001, the Fund adopted the provisions
     of the AICPA Audit and Accounting Guide for Investment Companies that
     requires 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.

NOTES                                           DELAWARE NATIONAL TAX-FREE FUNDS
   TO FINANCIAL STATEMENTS                      August 31, 2005


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(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 expense 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       Delaware Tax-Free        Delaware Tax-Free

  On the next $1.5 billion                           0.450%               0.450%                      0.450%

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

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. 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, the Funds paid DSC a monthly fee based on
average net assets subject to certain minimums for accounting and administration
services. Each Fund paid 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 aquired 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 29, 2005 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 August 31, 2005, the Funds had liabilities payable to affiliates as follows:

*DMC, as part of its administrative services, pays operating expenses on 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
each Fund by DMC employees. For the year ended August 31, 2005, each Fund was
charged for internal legal services provided by DMC as follows:

4. DIVIDEND AND DISTRIBUTION INFORMATION

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

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, 2004 through August 31, 2005 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 federal income tax purposes, each Fund had accumulated capital losses as of
August 31, 2005, which may be carried forward and applied against future capital
gains. Such capital loss carryfowards expire as follows:

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

NOTES                                           DELAWARE NATIONAL TAX-FREE FUNDS
   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 Funds 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 Funds' 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. PRE-REFUNDED BONDS
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 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 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 due to the strong credit quality of the
escrow securities and the irrevocable nature of the escrow deposit agreement.
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.




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:



                                                    (A)               (B)

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, Delaware Tax-Free
Insured Fund, and Delaware Tax-Free USA Intermediate Fund) and Delaware National
High-Yield Municipal Bond Fund (one of the series constituting Voyageur Mutual
Funds) (collectively, 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 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 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 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, 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 NATIONAL TAX-FREE FUNDS INVESTMENT ADVISORY
AGREEMENT

At a meeting held on May 18-19, 2005 (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 Insured Fund, Delaware Tax-Free USA Fund, Delaware Tax-Free USA
Intermediate Fund and Delaware National High-Yield Municipal Bond 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(R) 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.

BOARD CONSIDERATION OF DELAWARE NATIONAL TAX-FREE FUNDS INVESTMENT ADVISORY
AGREEMENT (CONTINUED)

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

DELAWARE TAX-FREE USA FUND -- The Performance Universe for this 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, three and five year periods was in the first quartile of
such Performance Universe. The report further showed that the Fund's total
return for the 10 year period was in the third quartile. The Board was satisfied
with such performance.




DELAWARE TAX-FREE USA INTERMEDIATE FUND -- The Performance Universe for this
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.

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 Insured Fund -- The expense comparisons for the Fund showed
that its management fee and 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.

BOARD CONSIDERATION OF DELAWARE NATIONAL TAX-FREE FUNDS INVESTMENT ADVISORY
AGREEMENT (CONTINUED)

DELAWARE TAX-FREE USA FUND -- The expense comparisons for the Fund showed that
its 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.

DELAWARE TAX-FREE USA INTERMEDIATE 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 NATIONAL HIGH-YIELD MUNICIPAL BOND FUND -- The expense comparisons for
the Fund showed that its 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 satisified 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(R) 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(R) 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(R) 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.

       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.

         (g) The aggregate non-audit fees billed by the registrant's independent
auditors for services rendered to the registrant and to its investment adviser

$215,035 and $218,065 for the registrant's fiscal years ended August 31,
2005 and August 31, 2004, respectively.






         (h) In connection with its selection of the independent auditors, the
registrant's Audit Committee has considered the independent auditors' provision

providers under common control with the adviser that were not required to be
pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X. The Audit

services is compatible with maintaining the auditors' independence.
