NOTES

1. SIGNIFICANT ACCOUNTING POLICIES
The following accounting policies are in accordance with U.S. generally accepted
accounting principles and are consistently followed by Delaware Investments
Florida Insured Municipal Income Fund (the "Fund").

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 the 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 - The 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.

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

OTHER - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Management fees and some other expenses are paid monthly. Security transactions
are recorded on the date the securities are purchased or sold (trade date).
Costs used in calculating realized gains and losses on the sale of investment
securities are those of the specific securities sold. Interest income is
recorded on the accrual basis. Discounts and premiums are amortized to interest
income over the lives of the respective securities. The Fund declares and pays
dividends from net investment income monthly and distributions from net realized
gain on investments, if any, annually. In addition, in order to satisfy certain
distribution requirements of the Tax Reform Act of 1986, the Fund may declare
special year-end dividend and capital gains distributions during November or
December to shareholders of record on a date in such month. Such distributions,
if received by shareholders by January 31, are deemed to have been paid by the
Fund and received by shareholders on the earlier of the date paid or December 31
of the prior year.

2. INVESTMENTS
At June 30, 2005, the cost of investments for federal income tax purposes has
been estimated since the final tax characteristics cannot be determined until
fiscal year end. At June 30, 2005, the cost of investments and unrealized
appreciation (depreciation) for the Fund were as follows:

Cost of investments                       $50,682,035
Aggregate unrealized appreciation           3,139,535
Aggregate unrealized depreciation             (21,347)
                                          -----------
Net unrealized appreciation               $ 3,118,188
                                          -----------

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


<PAGE>

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

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.

The 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 the Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so. At
June 30, 2005, there were no Rule 144A securities. None of the securities have
been determined to be illiquid under the Fund's Liquidity Procedures. While
maintaining oversight, the Board of Trustees has delegated to the investment
adviser the day-to-day functions of determining whether individual Rule 144A
securities are liquid for purposes of the Fund's limitation on investments in
illiquid assets.

                  conclusions about the effectiveness of the disclosure controls
                  and procedures, as of a date within 90 days prior to the
                  filing date of this report, based on such evaluation; and

         (d)      Disclosed in this report any change in the registrant's
                  internal control over financial reporting that occurred during
                  the registrant's most recent fiscal quarter that has
                  materially affected, or is reasonably likely to materially
                  affect, the registrant's internal control over financial
                  reporting; and

5.       The registrant's other certifying officer(s) and I have disclosed to
         the registrant's auditors and the audit committee of the registrant's
         board of directors (or persons performing the equivalent functions):

         (a)      All significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize, and report
                  financial information; and

         (b)      Any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrant's internal control over financial reporting.
