(1) Total return assumes an investment at the common share market price at the
    beginning of the period indicated, reinvestment of all distributions for the
    period in accordance with the Trust's dividend reinvestment plan, and sale
    of all shares at the closing common share market price at the end of the
    period indicated.

(2) Distribution rate represents the monthly annualized distributions of the
    Trust at the end of the period and not the earnings of the Trust.

Q&A WITH YOUR PORTFOLIO MANAGER

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF VAN KAMPEN TRUST FOR INSURED
MUNICIPALS ABOUT THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE MARKETS AND
INFLUENCED THE TRUST'S RETURN DURING THE SIX MONTHS ENDED APRIL 30, 2003. JOSEPH
PIRARO, PORTFOLIO MANAGER, HAS MANAGED THE TRUST SINCE 1992 AND HAS WORKED IN
THE INVESTMENT INDUSTRY SINCE 1971. THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS
ON THE TRUST'S PERFORMANCE.

Q   WHAT WAS THE MARKET
    ENVIRONMENT OF THE PAST SIX MONTHS, AND HOW DID THE TRUST PERFORM IN THAT
    ENVIRONMENT?

A   The environment over the past six
months has been defined by two major themes. The first of these was the level of
interest rates. The period began with interest rates at levels not seen in over
three decades and, surprisingly for many, ended with rates slightly lower. The
Federal Reserve Board (the Fed) helped keep rates low with a widely anticipated
rate cut in November, driven by economic uncertainty and geopolitical risk. The
low level of rates led to a boom in issuance by municipalities seeking to lock
in low financing costs. As a result, issuance reached a record level of $354
billion in 2002 and continued to be exceptional in the first quarter of 2003.

    The other theme in the market during the period was the relative
attractiveness of municipal bonds, which produced enough demand to absorb the
record issuance. Investors, wary of volatility in the equity market and in the
geopolitical arena, flocked to perceived safe haven investments. Their risk
aversion counteracted growing expectations for economic recovery and rising
interest rates and was a key factor in keeping interest rates at historically
low levels. In their ongoing preference for low-risk assets, investors bid
Treasury prices up to such high levels that municipal bonds became as
attractively valued as they have ever been relative to Treasuries. Insurance
companies also moved heavily into municipal bonds as their mainstay corporate
bond holdings became less attractive. At the same time, issuers recognized
investor concerns over economic weakness by insuring roughly 50 percent of all
issuance. This credit enhancement made municipal bonds even more attractive to
risk-averse investors.

    While lower financing costs were a boon to municipal issuers, the continuing
weakness in the economy had a negative impact on municipal credit quality,
particularly in the first quarter of 2003. Moody's upgrades barely exceeded the
number of downgrades in the first quarter, with

                                        4


credit quality facing continued pressure from rising social service costs and
weak national and regional economic conditions. As a result, municipalities face
enormous deficits in 2003, when their combined shortfall is expected to reach
$90 billion.

    Performance along the yield curve was varied. The Fed's November rate cut
fueled a rally in short-term bonds that helped pull yields lower at the front
end of the curve. Despite that rally, the best performing segment of the curve
was the long-intermediate portion, where performance was largely driven by
buying activity among institutional investors drawn by the bonds' attractive
total return potential.

    The trust's monthly dividend of $0.0920 per share translated to a
distribution rate of 6.36 percent based on the trust's closing common share
market price on April 30, 2003. Based on these figures, investors would have to
earn a distribution rate of 10.36 percent on a taxable investment (for an
investor in the 38.60 percent federal income tax bracket) to match the
tax-exempt yield provided by the trust.

    For the six months ended April 30, 2003, the trust produced a total return
of 13.92 percent based on common share market price. By comparison, the Lehman
Brothers Municipal Bond Index posted a total return of 3.59 percent for the same
period. Of course, past performance is no guarantee of future results.
Investment return, common share market price and net asset value will fluctuate
and trust shares, when sold, may be worth more or less than their original cost.
As a result of recent market activity, current performance may vary from the
figures shown. For more up-to-date information, please visit vankampen.com or
speak with your financial advisor.

    The Lehman Brothers Municipal Bond Index is an unmanaged, broad-based
statistical composite of municipal bonds. Index returns do not include any sales
charges or fees that would be paid by an investor purchasing the securities the
index represents. Such costs would lower performance. It is not possible to
invest directly in an index. For additional information, please refer to the
performance summary section.

Q   WHAT STRATEGIES DID YOU PURSUE
    IN MANAGING THE TRUST?

A   With interest rates hovering near
record lows, we focused on protecting the trust from the potential adverse
effects of rising interest rates while maintaining the trust's yield. One of the
main ways we did this was to adjust the trust's maturity profile by shifting
assets from the short end of the yield curve to securities with maturities
between 18 and 22 years and a shorter call date. Our quantitative analysis
showed that this segment of the yield curve offered the optimal combination of
total return potential as well as downside protection in the form of a
comfortable yield cushion and an intermediate maturity profile.

    We were similarly cautious in managing the portfolio's sector exposures.
Over the course of the period, we avoided securities from the health care and
housing sectors that offered less compelling structural and credit
characteristics. We focused

                                        5


instead on bonds backed by revenues from more mainstream municipal sectors such
as transportation and water and sewer. The transportation sector offered
particularly attractive value, especially among airport bonds. These securities
were hit hard by concerns over the financial health of airlines, which caused
investors to bid down the prices of most airport bonds. We took advantage of the
oversold state of the sector by adding to the trust's holdings of insured
airport bonds that were relatively cheap in spite of their credit protection.

    One of the sectors we avoided during the period was tobacco bonds. These
bonds were issued by states seeking to securitize their future income streams
resulting from settlements from class action suits against the major tobacco
companies. Recent litigation in Illinois resulted in a judge awarding billions
more in a suit alleging that the companies misled smokers about the amount of
nicotine in "light" cigarettes. In order to appeal, the law required the
companies to put up such substantial amounts of money that some began talking
about potential bankruptcy, and the tobacco bonds' credit ratings and price
performance suffered accordingly. Our decision not to invest in these securities
was a benefit to shareholders during the period.

 * Non-Annualized

(a) As required, effective November 1, 2001, the Trust has adopted the
    provisions of the AICPA Audit and Accounting Guide for Investment Companies
    and began accreting market discount on fixed income securities. The effect
    of this change for the year ended October 31, 2002 was to increase net
    investment income per share by less than $.01, decrease net realized and
    unrealized gains and losses per share by less than $.01, and increase the
    ratio of net investment income to average net assets applicable to common
    shares by .02%. Per share, ratios and supplemental data for periods prior to
    October 31, 2002 have not been restated to reflect this change in
    presentation.

(b) Total return assumes an investment at the common share market price at the
    beginning of the period indicated, reinvestment of all distributions for the
    period in accordance with the Trust's dividend reinvestment plan, and sale
    of all shares at the closing common share market price at the end of the
    period indicated.

(c) Ratios do not reflect the effect of dividend payments to preferred
    shareholders.

(d) Ratios reflect the effect of dividend payments to preferred shareholders.

(e) Calculated by subtracting the Trust's total liabilities (not including the
    preferred shares) from the Trust's total assets and dividing this by the
    number of preferred shares outstanding.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Trust for Insured Municipals (the "Trust") is registered as a
diversified, closed-end management investment company under the Investment
Company Act of 1940, as amended. The Trust's investment objective is to provide
a high level of current income exempt from federal income tax, consistent with
preservation of capital. In normal market conditions, the Trust intends to
invest substantially all of its assets in municipal securities which are covered
by insurance with respect to the timely payment of principal and interest. The
Trust commenced investment operations on January 24, 1992.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent 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.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when-issued or delayed delivery
purchase commitments until payment is made. At April 30, 2003, the Trust had
$5,002,067 of when-issued and delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    At April 30, 2003, the cost and related gross unrealized appreciation and
depreciation are as follows:

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed annually on a pro rata basis to common and preferred
shareholders. Distributions from net realized gains for book purposes may
include short-term capital gains, which are included as ordinary income for tax
purposes.

    The tax character of distributions paid during the year ended October 31,
2002 was as follows:

Trust's portfolio.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen
Investment Advisory Corp. (the "Adviser") will provide investment advice and
facilities to the Trust for an annual fee payable monthly of .55% of the average
daily net assets of the Trust. In addition, the Trust will pay a monthly
administrative fee to Van Kampen Investments Inc. or its affiliates
(collectively "Van Kampen"), the Trust's Administrator, at an annual rate of
..05% of the average daily net assets of the Trust. The administrative services
provided by the Administrator include record keeping and reporting
responsibilities with respect to the Trust's portfolio and preferred shares and
providing certain services to shareholders.

    For the six months ended April 30, 2003, the Trust recognized expenses of
approximately $5,800 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the six months ended
April 30, 2003, the Trust recognized expenses of approximately $17,800
representing Van Kampen's cost of providing accounting and legal services to the
Trust, which are reported as part of "Other" and "Legal" expenses, respectively,
in the Statement of Operations.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
officers of Van Kampen.

    The Trust provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable upon retirement for a
ten-year period and are based upon each trustee's years of service to the Trust.
The maximum annual benefit per trustee under the plan is $2,500.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate,
or index.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or fixed
income market changes, for duration management or for risk management purposes,
but may also enter into these transactions to generate additional income. All of
the Trust's portfolio holdings, including derivative instruments, are marked to
market each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract.

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an arrangement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures on U.S. Treasury Bonds and Notes
and typically closes the contract prior to the delivery date. Upon entering into
futures contracts, the Trust maintains an amount of cash or liquid securities
with a value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to the rules and regulations promulgated under the
1940 Act, as amended, or with its custodian in an account in the broker's name.
This amount is known an initial margin. During the period the futures contract
is open, payments are received from or made to the broker based upon changes in
the value of the contract (the variation margin). The risk of loss associated
with a futures contract is in excess of the variation margin reflected on the
Statement of Assets and Liabilities.
