PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF

SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT
VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL ADVISOR. INVESTMENT RETURNS, NET
ASSET VALUE (NAV) AND COMMON SHARE MARKET PRICE WILL FLUCTUATE AND TRUST SHARES,
WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

NAV per share is determined by dividing the value of the trust's portfolio
securities, cash and other assets, less all liabilities and preferred shares, by
the total number of common shares outstanding. The common share market price is
the price the market is willing to pay for shares of the trust at a given time.
Common share market price is influenced by a range of factors, including supply
and demand and market conditions. Total return assumes an investment at the
beginning of the period, reinvestment of all distributions for the period in
accordance with the trust's dividend reinvestment plan, and sale of all shares
at the end of the period. The trust's advisor has waived or reimbursed fees and
expenses from time to time; absent such waivers/reimbursements the trust's
returns would have been lower.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal bonds. The index does not include any expenses, fees or sales
charges, which would lower performance. The index is unmanaged and should not be
considered an investment. It is not possible to invest directly in an index.

Trust Report

FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2007

MARKET CONDITIONS

The overall environment for municipal bonds was favorable during the reporting
period, but mixed economic indicators and concerns about the residential housing
sector led to increased market uncertainty and volatility. At the beginning of
the period, the pace of economic growth appeared to be slowing, but in December,
the outlook for the economy turned positive following a slate of
stronger-than-expected economic releases. The improved economic picture pushed
bond yields higher and effectively reversed the run-up in prices that had begun
in July on concern over the weak housing market's potential drag on the economy.
Bonds continued to decline until February, when the sub-prime mortgage market
showed signs of deterioration, causing a sell-off in equities and a
flight-to-quality bond market rally. In March, the rally ended as strong
employment reports and upward movement in inflationary pressures sparked selling
in an overbought Treasury market. At month end, however, the short end of the
bond market rebounded strongly following news that the Federal Open Market
Committee (the "Fed") had dropped its bias toward higher rates. This came as
somewhat of a surprise, given the fact that core inflation readings remained
elevated.

Municipal bond yields followed the general movement of the Treasury market.
However, the 30-year AAA municipal yield reached lows not seen in decades,
declining to 4.00 percent in the first half of the reporting period before
reversing course and ending the period higher at 4.10 percent. Yields on the
short end of the municipal curve rose more than long-term yields during the
period. As a result, the short end of the curve posted the lowest returns while
the long end outperformed other portions of the curve by as much as 70 basis
points. The slope of the municipal curve (which is defined by the traditional
yield advantage of bonds with longer maturities) still remained relatively flat
and as such, the yield differential between long maturity and short maturity
issues was quite small.

New issue supply rose dramatically during the period, increasing by 34 percent
versus the same six-month period a year ago, as relatively low interest rates
spurred municipalities to refinance their debt. Insured bond issuance also rose
considerably and represented more than half of the total new issue supply.
Demand for municipal bonds was robust as well, particularly for high-yield
securities as investors proved increasingly willing to take on more risk in
return for relatively higher yields. The strong demand caused most credit
spreads, which were already near historically tight levels, to further narrow.
As a result, the lower-quality, higher yielding segment of the market
considerably outperformed, returning 182 basis points more than the
investment-grade segment for the overall period.

PERFORMANCE ANALYSIS

The Trust's return can be calculated based upon either the market price or the
net asset value (NAV) of its shares. NAV per share is determined by dividing the
value of the Trust's portfolio securities, cash and other assets, less all
liabilities and preferred shares, by the total number of common shares
outstanding, while market price reflects the supply and demand for the shares.
As a result, the two returns can differ, as they did during the reporting
period. On an NAV basis, the Trust underperformed its benchmark index, the
Lehman Brothers Municipal Bond Index. On a market price basis, the Trust
outperformed its benchmark.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. Investment return, net asset value and common share market price will
fluctuate and Trust shares, when sold, may be worth more or less than their
original cost. See Performance Summary for additional performance information
and index definition.

A variety of strategies drove the Trust's performance during the course of the
period. One of the key drivers was our focus on the long end of the yield curve.
Given the relatively flat shape of the curve throughout the period, we invested
in bonds with maturities of 25 years or more in order to capture more attractive
yields. The emphasis on longer-maturity issues proved beneficial to performance
as this segment of the curve outperformed for the overall period.

Recent fund enhancements allow for up to 20 percent of assets to be invested in
uninsured--but still investment-grade--securities. (The remainder must be
invested in AAA rated insured bonds.) As such, in an effort to further enhance
the Trust's yield, we selectively added holdings in BBB, A, and AA rated credits
while also adding to the Trust's holdings of inverse floating-rate securities.*
These strategies were additive to the Trust's performance during the first four
months of the period. In the last two months, however, spread widening led the
performance of lower-rated credits to wane and rising interest rates hurt the
performance of inverse floating-rate securities. As a result, the Trust's
positions in these credits detracted somewhat from performance late in the
period.

The primary contributor to the Trust's underperformance versus the Lehman
Brothers Municipal Bond Index during the period was its holdings in insured
bonds. The Trust contains a greater amount of insured bonds than the Lehman
Brothers Municipal Bond Index. Over the course of the period, spread widening in
the sector adversely affected performance of the Trust's holdings. This,

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.
                                                                               3


coupled with the portfolio's relative overweight to these bonds, detracted from
returns. Because the Trust's inverse floating-rate securities added to the
portfolio's duration (a measure of interest-rate risk), we hedged that risk by
selling 30-year U.S. Treasury futures. While this proved to be an effective
hedging strategy, it hindered the portfolio's return during the period. We
continued to keep the Trust's Alternative Minimum Tax (AMT) exposure low, but
holdings here also detracted from performance. The Trust remained well
diversified across a broad spectrum of municipal market sectors. As of the end
of the period, airports, hospitals and general purpose bonds represented the
portfolio's largest sector weightings.

The Trustees have approved a procedure whereby the trust may, when appropriate,
repurchase its shares in the open market or in privately negotiated transactions
at a price not above market value or NAV, whichever is lower at the time of
purchase. This may help support the market value of the trust's shares.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Trust in
the future.

CHANGES IN INVESTMENT POLICIES

The Board of Trustees of the Trust recently approved a non-fundamental
investment policy for the Trust allowing it to invest up to 20 percent of its
assets in unrated securities that have been determined by Van Kampen Asset
Management (the "Adviser") to be of comparable quality to those rated investment
grade.

Unrated securities may be less liquid than rated securities. This may have the
effect of limiting the ability of the Trust to sell such securities at their
fair value in response to changes in the economy or the financial markets.

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED)

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 (the "1940 Act"), as amended. The Trust's investment
objective is to seek to provide a high level of current income exempt from
federal income taxes, 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 last reported 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. Futures contracts are valued at the settlement price established each
day on the exchange on which they are traded. Interest rate swaps are valued
using market quotations obtained from brokers. 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
segregate assets with the custodian 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, 2007, there were no when-issued or 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 Subchapter M 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.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At October 31, 2006, the Trust had an

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 at least 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 and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the year ended October 31,
2006 was as follows:

                                                              $12,818,934
                                                              ===========
</Table>

    As of October 31, 2006, the components of distributable earnings on a tax
basis were as follows:

<Table>

Undistributed tax-exempt income.............................     908,602
Undistributed long-term capital gain........................         -0-
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of gains or losses recognized on securities for
tax purposes but not for book purposes.

F. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Trust enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interests in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Trust to retain residual interests in the
bonds. The Trust enters into shortfall agreements with the dealer trusts, which
commit the Trust to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Trust (inverse floating rate investments) include the
right of the Trust (1) to cause the holders of the floating rate notes to tender
their notes at par at the

                                                                              21

next interest rate reset date, and (2) to transfer the municipal bond from the
dealer trusts to the Trust, thereby collapsing the dealer trusts. The Trust
accounts for the transfer of bonds to the dealer trusts as secured borrowings,
with the securities transferred remaining in the Trust's investment assets, and
the related floating rate notes reflected as Trust liabilities under the caption
"Floating Rate Note Obligations" on the Statement of Assets and Liabilities. The
Trust records the interest income from the fixed rate bonds under the caption
"Interest" and records the expenses related to floating rate note obligations
and any administrative expenses of the dealer trusts under the caption "Interest
and Residual Trust Expenses" on the Trust's Statement of Operations. The notes
issued by the dealer trusts have interest rates that reset weekly and the
floating rate note holders have the option to tender their notes to the dealer
trusts for redemption at par at each reset date. At April 30, 2007, Trust
investments with a value of $69,324,453 are held by the dealer trusts and serve
as collateral for the $47,915,000 in floating rate notes outstanding at that
date. Contractual maturities of the floating rate notes and interest rates in
effect at April 30, 2007 are presented on the Portfolio of Investment.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset
Management (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
including preferred shares of the Trust. Effective December 1, 2006, the Adviser
has agreed to waive investment advisory fees equal to 0.10% of the average daily
net assets including preferred shares of the Trust. For the period ended April
30, 2007, the Adviser waived $101,992 of its advisory fees. This waiver is
voluntary and can be discontinued at any time.

    For the six months ended April 30, 2007, the Trust recognized expenses of
approximately $11,800 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Trust is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Trust.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Trust. The costs of
these services are allocated to each trust. For the six months ended April 30,
2007, the Trust recognized expenses of approximately $24,000 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Trust, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on 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
also 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

purposes of enhancing stockholder value and reducing the discount at which the
Trust's shares trade from their net asset value. For the period ended April 30,
2007, the Trust repurchased 20,700 of its shares at an average discount of 6.02%
from net asset value per share. The Trust expects to continue to repurchase its
outstanding shares at such time and in such amounts as it believes such activity
will further the accomplishment of the foregoing objectives, subject to the
review of the Trustees.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $46,415,828 and $40,632,208,
respectively.

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 the
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 under lying the futures contract.
Risks may arise as a result of the potential inability of the counterparties to
meet the terms of their contracts.

    Summarized below are the specific types of derivative financial instruments
used by the Trust.

A. FUTURES CONTRACTS A futures contract is an agreement 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 contracts on U.S. Treasury
securities and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the Trust's

                                                                              23


VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued

effective maturity and duration. 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 as 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.

    Transactions in futures contracts for the six months ended April 30, 2007
were as follows:

</Table>

B. INTEREST RATE SWAPS The Trust may enter into forward interest rate swap
transactions intended to help the Trust manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Trust's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Trust's agreement with a
counterparty to pay, in the future, a fixed or variable rate payment in exchange
for the counterparty paying the Trust a variable or fixed rate payment, the
accruals for which would begin at a specified date in the future (the "effective
date"). The amount of the payment obligation is based on the notional amount of
the forward swap contract and the termination date of the swap (which is akin to
a bond's maturity). The value of the Trust's swap commitment would increase or
decrease based primarily on the extent to which long-term interest rates for
bonds having a maturity of the swap's termination date increases or decreases.
The Trust may terminate a swap contract prior to the effective date, at which
point a realized gain or loss is recognized. When a forward swap is terminated,
it ordinarily does not involve the delivery of securities or other underlying
assets or principal, but rather is settled in cash on a net basis. The Trust
intends, but is not obligated, to terminate its forward swaps before the
effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Trust upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of the Trust with a value approximately equal to the amount of any
unrealized gain. Reciprocally, when the Trust has an unrealized loss on a swap
contract, the Trust has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash for segregating
purposes, if any, is shown on the Statement of Assets and Liabilities.

C. INVERSE FLOATING RATE SECURITIES The Trust may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued

in the dealer trust. These investments are typically used by the Trust in
seeking to enhance the yield of the portfolio. These instruments typically
involve greater risks than a fixed rate municipal bond. In particular, these
instruments are acquired through leverage or may have leverage embedded in them
and therefore involve many of the risks associated with leverage. Leverage is a
speculative technique that may expose the Trust to greater risk and increased
costs. Leverage may cause the Trust's net asset value to be more volatile than
if it had not been leveraged because leverage tends to magnify the effect of any
increases or decreases in the value of the Trust's portfolio securities. The use
of leverage may also cause the Trust to liquidate portfolio positions when it
may not be advantageous to do so in order to satisfy its obligations with
respect to inverse floating rate instruments.

6. PREFERRED SHARES

The Trust has outstanding 3,600 Auction Preferred Shares (APS) in two series of
1,800 shares each. Dividends are cumulative and the dividend rates are generally
reset every 28 days for both series through an auction process. The average rate
in effect on April 30, 2007 was 3.800%. During the six months ended April 30,
2007, the rates ranged from 3.320% to 3.890%.

    The Trust pays annual fees equivalent to .25% of the preferred share
liquidation value for the remarketing efforts associated with the preferred
auctions. These fees are included as a component of "Preferred Share
Maintenance" expense on the Statement of Operations.

    The APS are redeemable at the option of the Trust in whole or in part at the
liquidation value of $25,000 per share plus accumulated and unpaid dividends.
The Trust is subject to certain asset coverage tests and the APS are subject to
mandatory redemption if the tests are not met.

7. INDEMNIFICATIONS

The Trust enters into contracts that contain a variety of indemnifications. The
Trust's maximum exposure under these arrangements is unknown. However, the Trust
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

8. ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes--an interpretation
of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes
by prescribing the minimum recognition threshold a tax position must meet before
being recognized in the financial statements. FIN 48 is effective for the fiscal
years beginning after December 15, 2006 and is to be applied to all open tax
years as of the effective date. Recent SEC guidance allows implementing FIN 48
in the trust NAV calculations as late as the trust's last NAV calculation in the
first required financial statement period. As a result, the Trust will
incorporate FIN 48 in its semi annual report on April 30, 2008. The impact to
the Trust's financial statements, if any, is currently being assessed.

                                                                              25


VAN KAMPEN TRUST FOR INSURED MUNICIPALS

    In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Trust's financial statement disclosures.
