Investment 
Objectives and 
Strategies

(PHOTO) [glasses, pen, calculator, papers]

EACH OF THE SIX FUNDS in this report are closed-end management investment
companies whose shares trade on the American Stock Exchange (ASE) in New 
York. Each Fund seeks to provide high current income exempt from federal 
income tax and from the personal income tax of its state, if any, consistent 
with the preservation of capital. In addition, Florida Insured Municipal 
Income Fund seeks investments that enable its shares to be exempt from 
Florida's intangible personal property tax. Each Fund seeks to achieve its 
objective by investing at least 80% of its net assets in investment grade, 
tax-exempt municipal obligations.


INVESTMENT ADVISER
Delaware Management Company, Inc. has been the Funds' investment adviser since
May 1, 1997. At a meeting on April 11, 1997, the shareholders of each Fund
approved a new investment advisory agreement with Delaware Management that
became effective May 1, 1997. On May 30, 1997, Voyageur Fund Managers, Inc. the
Funds' prior investment adviser, merged into Delaware Management. Delaware
Management is a part of Lincoln National Corporation, one of America's largest
publicly held, diversified financial services companies, with global insurance
operations and more than $120 billion in assets under management.
        Delaware currently manages more than $40 billion for mutual fund 
shareholders and institutional investors such as pension plans and 
foundations. In addition, Delaware manages closed-end equity funds traded on 
the New York Stock Exchange.


LEVERAGING
Each of the six funds in this report uses leveraging, a tool that is not
available to open-end mutual funds and one that can be an important contributor
to each Fund's income and capital appreciation potential. Of course, there is no
guarantee any of the Funds will achieve this. Leveraging could result in a
higher degree of volatility because the Fund's net asset value could be more
sensitive to fluctuations in short-term interest rates and equity prices.
Delaware believes this volatility risk is reasonable given the benefits of
higher income potential.


MUNICIPAL LEASE OBLIGATIONS
The Funds may invest without limitation in state or municipal leases and 
participation interests therein. These fixed-income securities are generally
illiquid. Municipal leases are obligations issued by state and local governments
or authorities to finance the acquisition of equipment and facilities such as
fire, sanitation or police vehicles or telecommunications equipment, buildings
or other capital assets.

OCTOBER 31, 1997

Dear Shareholder:
WE ARE PLEASED TO PRESENT THE FIRST REPORT OF DELAWARE-Voyageur's closed-end 
municipal bond funds since these six funds joined the Delaware family this 
past spring.
        For the first half of fiscal 1998, each Fund outperformed both its 
peers and the two unmanaged Lehman Brothers Municipal Bond Indexes shown on 
page 2. We achieved a remarkable level of success amid a period of relatively 
high bond market volatility and the most significant federal tax legislation 
in more than a decade.
        We believe your Funds' superior results are attributable to the 
benefits of leveraging and to our strategic positioning in longer term bonds. 
Prices of longer term bonds also benefited more than those with shorter 
maturities as fear of higher U.S. inflation ebbed amid encouraging government 
economic reports.
        This past March, after seeing signs of strong U.S. economic growth, 
the Federal Reserve Board raised its target for short-term U.S. interest 
rates by 25 basis points (0.25%) to 5.5%. Bond prices slumped, with yields on
30-year U.S. Treasury securities rising to 7.18%.
        Yet, in just a few weeks, fixed-income markets reversed course. 
Tax-exempt bonds enjoyed a sustained rally that lasted through the end of 
September. Yields on high quality municipal bonds, which move inversely to 
prices, generally declined between 40 and 50 basis points (0.40% to 0.50%).
        We are particularly proud that the Florida Insured Municipal Income 
Fund maintained a record of superior performance under the new leadership of
two Delaware portfolio managers - Mitchell L. Conery and Patrick P. Coyne.
As shown on page 10, the Fund ranked #1 among its peers for the six, 12 and
36-month periods ended September 30, 1997.

       Most municipal income closed-end funds trade at modest discounts to
their net asset value. We are pleased to report the level of discount on five 
of the Funds in this report narrowed during the six months ended September 
30, 1997. In addition, Minnesota Municipal Income Fund I traded at the 
highest premium to its net asset value since the summer of 1996.

Portfolio Manager's Review

As shown on page 2, the Delaware family's three closed-end Minnesota
municipal bond funds provided above-average total returns during the first 
half of fiscal 1998 despite substantial interest rate volatility and renewed 
efforts in Washington to cut income taxes.
        With a below-average unemployment rate and an annualized economic 
growth rate of  4.8% that ranks 10th nationwide, Minnesota exhibits credit 
characteristics attractive to income-oriented investors. Per capita income in
the state is the highest of all Plains states, according to the Cato Institute,
and ranks 9th nationwide while the state's general obligation bonds carry a 
quality rating of AAA, the highest available.
        Between March and September, yields on longer term Minnesota general 
obligation bonds declined as much as 50 basis points (0.50%) as bond prices 
rose. We believe our strong results were attributable to our positioning in 
long term bonds. We took a relatively optimistic view of fixed-income 
markets, and the average effective duration of each Fund's portfolio was 
generally longer than most of our competitors.

HIGH VOLATILITY, 
LOWER BOND SUPPLY
Volatility, however, was high: bonds rallied in July, fell in August and 
rallied again in September. During this period, prices rose more than they 
fell, U.S. economic growth was strong and consumer price increases were 
subdued.
        In our opinion, one factor helping each Fund's performance during the 
first half of fiscal 1998 was a reduced supply of new Minnesota bonds. From 
December 1996 to September, 1997, the supply of new municipal bonds issued in 
the state declined by more than 14% to an annualized pace of $2.5 billion, 
according to THE BOND BUYER, a

trade publication. This has helped support the state's bond prices since
investor demand for Minnesota securities providing tax-exempt income has
remained steady.

AN EMPHASIS ON 
HIGH QUALITY
More than half of the net assets of each Fund's portfolio was invested in 
Minnesota bonds rated AAA as of September 30, 1997. Minnesota Municipal 
Income Funds II and III had slightly more invested in bonds rated AAA than 
Minnesota Municipal Income Fund I. In our opinion, this difference helped 
Funds II and III achieve higher returns than Fund I during the first half of 
fiscal 1998.
        Bonds rated AAA are the most sensitive to changes in Federal Reserve 
interest rate policy and investor perceptions about future inflation. Hence, 
Funds II and III benefited the most as rates and inflation expectations 
declined between March and September, in our opinion.
        Fund I traded at a modest premium to its net asset value as of 
September 30, 1997, whereas Funds II and III traded at a modest discount. We 
believe this reflected the fact that Fund I's average coupon was slightly 
higher than that of II and III during the first half of the fiscal year, 
offering investors additional income potential, all other factors being 
equal.

<PAGE>

        During the first half of fiscal 1998, I increased our focus on Minnesota
bonds that in our opinion offered good call protection features and were selling
at a discount to face value. This, plus relatively long maturities, enabled each
Fund to outpace the unmanaged Lehman Brothers Municipal Bond Index, our
benchmark.

SUMMARY OUTLOOK
Overall, it appears the capital markets have regained confidence that the Fed 
will move in a more restrictive monetary policy at the first signs of 
inflation. The Minnesota economy, meanwhile, continues to grow at a steady 
pace, providing municipal governments with robust amounts of tax revenue.
        In managing each Fund's portfolio, we will continue to seek good 
structure - a prudent combination of average coupon, call date and effective 
maturity that represent the mathematical underpinnings of the portfolio. By 
managing duration as conditions warrant, we will seek to maximize each Fund's 
income and total return potential.

Portfolio Manager's Review

For the first half of fiscal 1998, Arizona Municipal Bond Fund outperformed
its peers and its unmanaged benchmark, the Lehman Brothers Municipal Bond 
Index. The Fund provided a total return of +10.00% for the six months ended 
September 30, 1997 (capital change plus reinvested dividends at net asset 
value).
        With a population just over 3.7 million and a per capita income that's
growing at an annualized rate of 4.4%, Arizona exhibited characteristics we
believe are attractive to income-oriented investors.
        Arizona residents have enjoyed considerable tax relief in the 1990s. 
More than $1.5 billion in tax cuts have been enacted in recent years. The top 
marginal state tax rate on income has fallen from 7% in 1991 to 5.6% in 1996, 
according to the Cato Institute. The state's finances, meanwhile, are 
healthy. Arizona maintained a $400 million budget surplus in fiscal 1996 on 
revenues of $4.7 billion.
        Most municipal bonds issued in Arizona in calendar 1997 have been 
protected by private insurance guaranteeing the payment of principal and 
interest. Since December 1996, the supply of new municipal bonds in the state 
has grown by 43% to an annualized pace of $2.3 billion, according to THE BOND 
BUYER, a trade publication.
        General obligation bonds made up the largest component of your Fund's 
net assets at mid-year, followed by water and sewer bonds.

This reflected Arizona's growing population base, as most general obligation
bonds in your Funds portfolio were issued for school improvements. The state 
also has a higher-than-average number of municipal water projects, reflecting 
its arid climate.
        By focusing on higher yielding securities, we were able to provide 
most of the income available from the longest term municipal bonds with much 
less interest rate risk. 
        In addition to maintaining a strong weighting in general obligation 
bonds, we expect our strategy for the coming months will include focusing on 
bonds with higher-than-average yields, since these issues tend to be less 
affected by short-term swings in interest rates. In our opinion, interest 
rates are unlikely to move significantly lower in the coming months even if 
inflation does not accelerate. In general, we will also seek bonds with good 
call protection features and relatively shorter maturities.

Florida Insured Municipal Income Fund

Portfolio Managers' Review


We are pleased to report that Florida Insured Municipal Income Fund provided
an exceptionally strong total return of +11.21% for the six months ended
September 30, 1997 (capital change plus reinvested dividends at net asset
value).
        Despite a 24.5% surge in the amount of new bonds issued in Florida 
during calendar 1997, the state's municipal securities have performed well. 
In our opinion, this reflected a strong state economy as well as the fact that
more than 70% of municipal bonds issued in Florida were protected by private
insurance guaranteeing the payment of principal and interest when due.
        With a population just over 13 million and a per capita income that's
growing at an above-average annualized rate of 4.8%, Florida exhibited
characteristics that we believe are attractive to income - oriented investors.
Florida's growth and demographic makeup generate a substantial need for public
financing in the health care industry. This sector represented the largest
portion of Florida Insured Municipal Income Fund's portfolio as of September 30.
        Florida has no state income tax, so the primary advantage of owning 
Florida municipal securities is that income is exempt from federal income 
taxes. Also, we prefer

to select Florida bonds that are exempt from the state's intangibles tax on
assets.
        When the bond market weakened in April, we saw an opportunity to 
modestly extend duration  to increase income potential. The Fund also 
benefited by generally avoiding certain areas of South Florida such as Miami, 
where credit quality remains a concern. We were also underweighted in the
electric utility sector, particularly cogeneration plants. Increased industry
competition and legal issues have made it difficult for some alternative power
producers to be profitable, increasing the sector's credit risks.

        We are optimistic that investor demand for Florida bonds could increase
in the coming months among high tax brackets investors. One reason: regulators
in Tallahassee are more vigorously enforcing compliance with the state's
intangibles tax on bonds and stocks. In our opinion, that could prompt some
investors to switch assets from corporate bonds and mortgage-backed securities
(both of which are subject to the intangibles tax) to Florida securities, which
are exempt.
        In Florida and across the U.S., inflation appears to be benign. 
Despite a strong U.S. economy, the Federal Reserve Board has been able to 
effectively control consumer price increases. Should interest rates remain 
stable or decline for the balance of 1997, we believe municipal bond investments
could potentially provide an attractive real rate of return.
        In our opinion, the long-term outlook for Florida's economy and bond 
market is bright. Municipalities will continue to need capital from private 
investors to meet the needs of a growing population in the nation's fourth 
largest state, presenting investors with many income opportunities.

Portfolio Manager's Review

Colorado Insured Municipal Income Fund provided a relatively strong total
return of +9.59% for the six months ended September 30, 1997 (at net asset 
value with dividends reinvested). The Fund outpaced the unmanaged Lehman 
Brothers Insured Municipal Bond Index by some 270 basis points (2.7%).
        We attribute our results to a positioning that sought to capitalize 
on declining interest rates. For much of the period, we kept the Fund's 
duration (sensitivity to interest rates) longer than that of the Lehman 
index.
        While the Fund has consistently strived to maximize total return, 
since March we have taken steps to augment the Fund's yield. The Fund 
continues to invest exclusively in the highest rated investment grade 
municipal bonds.
        We have been attempting to improve the Fund's dividend yield by 
selling lower yielding bonds with short call periods and replacing them with 
higher yielding bonds with longer call protection periods. Colorado's strong
economy permitted us to make these swaps on favorable terms. 
        In Denver and other parts of the state, we believe strength in 
non-residential construction, high technology industries and financial 
services should continue to fuel Colorado's economic growth for the

                             1997 semi-annual report

next few years. Economists anticipate job growth will remain steady in 1997
while the state's unemployment rate is expected to fall to about 3.5% by year's
end, well below the national average.
        Consumer price inflation is higher in Colorado than in other states. 
Prices are rising at a 4% annual pace compared to about 3% nationwide, 
according to regional labor officials. However, this is offset by annual 
growth in personal income - about 7% - that has been and is expected to 
continue to be much higher than the national average. Colorado residents' per 
capita income ranks 13th among states.
        We believe Colorado's key economic strength going into the 
21st Century will be its diversity. A hub for communications and 
trans-portation, the state also has a strong manufacturing base, health care 
industry and tourism sector. For the fourth straight year, Colorado received 
the highest possible grade for economic performance in the Corporation for 
Enterprise Development's 1996 Report Card, an objective ranking based on 
economic performance.
        In our opinion, this bodes well for the credit quality of the state's 
bond market. According to the Cato Institute, the state's finances are helped 
by constitutional caps on spending and "by one of the nation's most anti-tax 
electorates."

(1)  For federal income tax purposes, all of the net investment income
     distributions were derived from interest on securities exempt from federal
     income tax.
(2)  Total investment return is calculated assuming a purchase of common stock
     on the opening of the first day and a sale on the closing of the last day
     of each period reported. Dividends and distributions, if any, are assumed
     for the purposes of this calculation, to be reinvested at prices obtained
     under the Fund's dividend reinvestment plan. Generally, total investment
     return based on net asset value will be higher than total investment return
     based on market value in periods where there is an increase in the discount
     or a decrease in the premium of the market value to the net asset value
     from the beginning to the end of such periods. Conversely, total investment
     return based on net asset value will be lower than total investment return
     based on market value in periods where there is a decrease in the discount
     or an increase in the premium of the market value to the net asset value
     from the beginning to the end of such periods. The total investment returns
     calculated based on market value and net asset value for a period of less
     than one year have not been annualized.
(3)  Ratios calculated on the basis of expenses and net investment income
     applicable to both the common and preferred shares relative to the average
     net assets of common and preferred shareholders.
(4)  Beginning in the year ended March 31, 1996, the expense ratio reflects the
     effect of gross expenses attributable to earnings credits on uninvested
     cash balances received by the Fund. Prior period expense ratios have not
     been adjusted.
(5)  Ratio reflects total net investment income less dividends paid to preferred
     shareholders from net investment income dividend by average net assets
     applicable to common stock.
(6)  Excluding any accumulated but unpaid dividends.

*  Commencement of operations     
** Annualized

(1) For federal income tax purposes, all of the net investment income
    distributions were derived from interest on securities exempt from federal
    income tax.
(2) Total investment return is calculated assuming a purchase of common stock on
    the opening of the first day and a sale on the closing of the last day of
    each period reported. Dividends and distributions, if any, are assumed for
    the purposes of this calculation, to be reinvested at prices obtained under
    the Fund's dividend reinvestment plan. Generally, total investment return
    based on net asset value will be higher than total investment return based
    on market value in periods where there is an increase in the discount or a
    decrease in the premium of the market value to the net asset value from the
    beginning to the end of such periods. Conversely, total investment return
    based on net asset value will be lower than total investment return based on
    market value in periods where there is a decrease in the discount or an
    increase in the premium of the market value to the net asset value from the
    beginning to the end of such periods. The total investment returns
    calculated based on market value and net asset value for a period of less
    than one year have not been annualized.
(3) Ratios calculated on the basis of expenses and net investment income
    applicable to both the common and preferred shares relative to the average
    net assets of common and preferred shareholders.
(4) Beginning in the year ended March 31, 1996, the expense ratio reflects the
    effect of gross expenses attributable to earnings credits on uninvested cash
    balances received by the Fund. Prior period expense ratios have not been
    adjusted.
(5) Ratio reflects total net investment income less dividends paid to preferred
    shareholders from net investment income dividend by average net assets
    applicable to common stock.
(6) Excluding any accumulated but unpaid dividends.

(1) For federal income tax purposes, all of the net investment income
    distributions were derived from interest on securities exempt from federal
    income tax.
(2) Total investment return is calculated assuming a purchase of common stock on
    the opening of the first day and a sale on the closing of the last day of
    each period reported. Dividends and distributions, if any, are assumed for
    the purposes of this calculation, to be reinvested at prices obtained under
    the Fund's dividend reinvestment plan. Generally, total investment return
    based on net asset value will be higher than total investment return based
    on market value in periods where there is an increase in the discount or a
    decrease in the premium of the market value to the net asset value from the
    beginning to the end of such periods. Conversely, total investment return
    based on net asset value will be lower than total investment return based on
    market value in periods where there is a decrease in the discount or an
    increase in the premium of the market value to the net asset value from the
    beginning to the end of such periods. The total investment returns
    calculated based on market value and net asset value for a period of less
    than one year have not been annualized.
(3) Ratios calculated on the basis of expenses and net investment income
    applicable to both the common and preferred shares relative to the average
    net assets of common and preferred shareholders.
(4) Beginning in the year ended March 31, 1996, the expense ratio reflects the
    effect of gross expenses attributable to earnings credits on uninvested cash
    balances received by the Fund. Prior period expense ratios have not been
    adjusted.
(5) Ratio reflects total net investment income less dividends paid to preferred
    shareholders from net investment income dividend by average net assets
    applicable to common stock.
(6) Excluding any accumulated but unpaid dividends.

The Delaware-Voyageur Funds -
Notes to Financial Statements September 30, 1997
(Unaudited)
- --------------------------------------------------------------------------------

Delaware-Voyageur Minnesota Municipal Income Fund, Inc. (formerly Voyageur
Minnesota Municipal Income Fund, Inc.) ("Minnesota Municipal Fund"); 
Delaware-Voyageur Minnesota Municipal Income Fund II, Inc. (formerly Voyageur 
Minnesota Municipal Income Fund II, Inc.), ("Minnesota Municipal II Fund"); 
Delaware-Voyageur Minnesota Municipal Income Fund III, Inc. (formerly 
Voyageur Minnesota Municipal Income Fund III, Inc.) (Minnesota Municipal III 
Fund"); Delaware-Voyageur Arizona Municipal Income Fund, Inc. (formerly 
Voyageur Arizona Municipal Income Fund, Inc.) ("Arizona Municipal Income 
Fund"); Delaware-Voyageur Florida Insured Municipal Income Fund (formerly 
Voyageur Florida Insured Municipal Income Fund) ("Florida Insured Municipal 
Fund") and Delaware-Voyageur Colorado Insured Municipal Income Fund, Inc. 
(formerly Voyageur Colorado Insured Municipal Income Fund Inc.) ("Colorado 
Insured Municipal Fund") (collectively referred to as the "Funds") are 
registered under the Investment Company Act of 1940 (as amended) as 
closed-end management investment companies. The Minnesota Municipal II, 
Florida Insured Municipal and Arizona Municipal Funds are registered as 
diversified funds. The Minnesota Municipal, Minnesota Municipal III and 
Colorado Insured Municipal Funds are registered as non-diversified funds. The 
Funds' shares trade on the American Stock Exchange.

The investment objective of each Fund is to provide high current income 
exempt from federal income tax and from the personal income tax of its state, 
if any, consistent with the preservation of capital. Florida Insured 
Municipal Fund will generally seek investments that will enable its shares to 
be exempt from Florida's intangible personal property tax. Each Fund will 
seek to achieve its investment objective by investing substantially all of 
its net assets in investment grade, tax-exempt municipal obligations of its 
respective state.

1. Fund Reorganization
On April 30, 1997, Lincoln National Corporation ("LNC") acquired Voyageur 
Fund Manager Inc.'s ("Voyageur") parent, Dougherty Financial Group, Inc. 
("DFG") pursuant to an agreement and plan of merger dated January 15, 1997, 
in which LNC would acquire DFG including the mutual fund investment advisory 
business of DFG conducted by Voyageur. Upon completion of the acquisition, 
Delaware Management Company, Inc. ("DMC") became the Investment Manager to 
the Funds.

2. Significant Accounting Policies
The following accounting policies are in accordance with 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. Money market instruments 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 by or under the 
direction of the Fund's Board of Directors/Trustees.

<PAGE>

Federal Income Taxes - Each Fund intends to continue to qualify 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. Income and capital gain distributions are 
determined in accordance with federal income tax regulations which may differ 
from generally accepted accounting principles.

Other - Expenses common to all Funds within the Delaware-Voyageur Funds are 
allocated amongst the Funds on the basis of average net assets. 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. Original issue discounts are 
accreted to interest income over the lives of the respective securities. The 
Funds intend to pay monthly dividends from net investment income. Capital 
gains, if any, are distributed annually.

Use of Estimates - The preparation of financial statements in conformity with 
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.

3. Investment Management, Administration and Transactions with Affiliates
Commencing May 1, 1997, and in accordance with the terms of their respective 
Investment Management Agreements, the Funds pay DMC, the Investment Manager 
of each Fund an annual fee of .40% which is calculated daily based upon the 
average daily net assets of each Fund, including assets attributable to any 
preferred stock that may 
be outstanding.

Prior to May 1, 1997, the Funds had an Investment Advisory and Management 
Agreement with Voyageur. Voyageur received a fee for its Investment Advisory 
and Management services based upon the average daily net assets of the Funds, 
including assets attributable to any preferred stock that was outstanding, at 
an annual rate of 0.40% for each Fund.

The Funds have Administrative Agreements with Mitchell Hutchins Asset Management
Inc. and Princeton Administrators, L.P. (on Colorado Insured Municipal Fund
only) (the "Administrators").

The Administration Agreements provide the Administrators with a monthly fee 
computed at an annual rate of .15% of each Fund's average daily net assets, 
including assets attributable to any preferred stock that may be outstanding. 
Certain Funds have minimum annual fees payable to the Administrators. The 
Minnesota Municipal Fund paid the minimum fee for the six months ended 
September 30, 1997.

For federal income tax purposes, as of March 31, 1997, Minnesota Municipal II 
Fund, Minnesota Municipal III Fund, Arizona Municipal Fund, Florida Insured 
Municipal Fund and Colorado Insured Municipal Fund had capital loss 
carryforwards of $2,612,098, $2,889,387, $895,746, $467,062 and $1,609,433, 
respectively, that will expire in years 2002 through 2005 if not offset by 
subsequent realized capital gains.

5. Capital Stock
Pursuant to their articles of incorporation, Minnesota Municipal Fund, 
Minnesota Municipal II Fund, Minnesota Municipal III Fund, Arizona Municipal 
Fund and Colorado Insured Municipal Fund each have 200 million shares of 
$0.01 par value common shares authorized. Florida Insured Municipal has been 
authorized to issue an unlimited amount of $0.01 par value common shares.

For the six months ended September 30, 1997 and the year ended March 31, 
1997, the Funds did not have any transactions in common shares.

The Funds each have one million shares of $0.01 par value preferred shares 
authorized, except for Florida Insured Municipal Fund which has an unlimited 
amount of $0.01 par value preferred shares authorized. Under resolutions 
adopted by the Board of Directors/Trustees, Minnesota Municipal Fund is 
allowed to issue up to 400 preferred shares, of which the entire amount was 
issued on August 6, 1992. On May 14, 1993, Minnesota Municipal II Fund, 
Arizona Municipal Fund and Florida Insured Municipal Fund issued 1,200, 500 
and 400 preferred shares, respectively. On December 10, 1993, Minnesota 
Municipal III Fund issued 300 preferred shares and on September 23, 1993, 
Colorado Insured Municipal Fund issued 800 preferred shares. The preferred 
shares have a liquidation preference of $50,000 per share plus any amount 
equal to accumulated but unpaid dividends.

Dividends for the outstanding preferred shares of each Fund are cumulative at 
a rate established at the initial public offering and are typically reset 
every 28 days based on the results of an auction. Dividends rates (adjusted 
for any capital gain distributions) ranged from 3.60% to 3.80% on Minnesota 
Municipal Fund, from 3.55% to 3.90% on Minnesota Municipal II Fund, from 
3.58% to 3.85% on Minnesota Municipal III Fund, from 3.20% to 3.80% on 
Arizona Municipal Fund, from 3.60% to 3.85% on Florida Insured Municipal Fund 
and from 3.35% to 3.70% on Colorado Insured Municipal Fund during the period 
ended September 30, 1997. Smith Barney Inc. and Merrill Lynch, Pierce, Fenner 
& Smith Incorporated (on Colorado Insured Municipal Fund only), as the 
remarketing agents, receive an annual fee from each of the Funds of .25% of 
the average amount of preferred stock outstanding.

Under the 1940 act, the Funds may not declare dividends or make other 
distributions on common shares or purchase any such shares if, at the time of 
the declaration, distribution or purchase, asset coverage with respect to the 
outstanding preferred stock is less than 200%. The preferred shares are 
redeemable at the option of the Funds, in whole or in part, on any dividend 
payment date at $50,000 per share plus any accumulated but unpaid dividends 
whether or not declared. The preferred shares are also subject to mandatory 
redemption at $50,000 per share plus any accumulated but unpaid dividends, 
whether or not declared, if certain requirements relating to the composition 
of the assets and liabilities of each Fund is not satisfied. The holders of 
preferred shares have voting rights equal to the holders of common shares 
(one vote per share) and will vote together with holders of common shares as 
a single class. However, holders of preferred shares are also entitled to 
elect two of each Fund's

                     1997 semi-annual report     35
<PAGE>

Directors/Trustees. In addition, the 1940 Act requires that along with approval
by shareholders that might otherwise be required, the approval of the holders of
a majority of any outstanding preferred shares, voting separately as a class
would be required to (a) adopt any plan of reorganization that would adversely
affect the preferred shares, and (b) take any action requiring a vote of
security holders pursuant to Section 13(a) of the 1940 Act, including, among
other things, changes in each of the Funds'subclassification as a closed-end
investment company or changes in their fundamental investment restrictions.

6. Concentration of Credit Risk
The Funds concentrate their investments in limited geographical areas. 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 
the market 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 Statement of Net Assets.

The Funds may invest up to 15% of its total assets in illiquid securities 
which may include securities with contractual restrictions on resale, 
securities exempt from registration under Rule 144A of the Securities Act of 
1933, as amended, and other securities which may not be readily marketable. 
The relative illiquidity of some of these securities may adversely affect the 
Funds' ability to dispose of such securities in a timely manner and at a fair 
price when it is necessary to liquidate such securities. These securities, if 
any, have been identified in the Statement of Net Assets.

Dividend Reinvestment Plans

Each Fund offers an automatic dividend reinvestment program. If Fund shares are
registered in your name and you are not already reinvesting dividends but would
like to do so, contact the dividend plan agent, Norwest Bank, Minnesota, NA at
1.800.468.9716. You will be asked to put your request in writing. If you have
shares registered in "street" name, contact your financial adviser or the
broker/dealer holding the shares.
        Under the Funds' current policies, all distributions of net 
investment income and capital gains to common stock shareholders are 
automatically reinvested in additional shares unless shareholders elect to 
receive all dividends and other distributions in cash paid by check mailed 
directly to the shareholders by the dividend plan agent.
        After each Fund declares a dividend or determines to make a capital 
gains distribution, the plan agent will, as agent for the participants, 
receive the cash payment and use it to buy shares in the open market on the 
American Stock Exchange. The Funds will not issue any new shares in 
connection with the plan.
