Dear Shareholder:

The US financial markets withstood a host of unfavorable factors to deliver a
year of positive investment returns. Record energy prices took a significant
bite out of household budgets and raised operating costs for industry. Higher
short-term interest rates made borrowing more expensive. Two catastrophic
hurricanes exacted an enormous personal toll from Americans living in the Gulf
Coast: the storms claimed lives, disrupted energy flows and dealt a sharp blow
to local job markets. Yet, the US economy moved ahead at a healthy pace during
the 12-month period that began December 1, 2004 and ended November 30, 2005.

Fixed income markets delivered modest gains

In this environment, the US fixed income markets delivered positive but modest
returns. Short-term interest rates rose steadily as the Federal Reserve Board
raised a key intrabank lending rate. Longer-term rates remained low during most
of the year. However, the yield on the 10-year US Treasury note, a bellwether
for the bond market edged up to 4.5% by the end of this reporting period. In
this environment, most domestic bond market sectors delivered low single-digit
returns. Generally, high-yield bonds continued to perform well despite a
setback in the spring, when bonds of certain high profile companies were
downgraded. However, municipal bonds generally performed better than high yield
bonds--even before accounting for their tax-exempt status--as state revenues
increased and budgets stabilized.

In the pages that follow, your fund's manager discusses key factors that
influenced performance. We urge you to read this report carefully and discuss
any questions you might have with your financial advisor.

As always, we thank you for choosing Colonial Funds.

Sincerely,

/s/ Christopher L. Wilson

    PORTFOLIO MANAGER'S REPORT


For the 12-month period ended November 30, 2005, Colonial Insured Municipal
Fund had a return of negative 0.52%, based on its market price. Changes in the
market price of the fund's shares reflect investor demand and are not
necessarily linked directly to changes in the fund's net asset value. The fund
returned 5.43%, based on investment at net asset value. The average return of
the fund's peer group, the Lipper Insured Municipal Debt Funds (Leveraged)
Category, was 4.91% over the same period./1/

Longer-maturity, non-callable bonds drove performance

A combination of significant events -- including successive Federal Reserve
rate hikes, record high oil prices, a devastating hurricane season combined
with generally benign inflation -- helped create an unusual scenario in the
bond market: the gap between short- and long-term interest rates narrowed as
short-term rates rose and rates on bonds with maturities longer than 15 years
generally ended the period lower. Bond yields and prices move in opposite
directions. This environment benefited the fund, which held a relatively large
position in bonds with maturity dates 20 years and longer.

Many of the fund's long-term holdings are also non-callable, which means the
issuer cannot redeem the bonds prior to maturity. These bonds did well because
they performed in line with their stated maturities, whereas the market priced
longer-term callable bonds to their call dates.

Leveraged positions helped returns

The fund earned some of its income through leverage, which comes from preferred
shares issued in 1999 that allow the trust to borrow against its underlying
investments. We invested the proceeds from the preferred shares in longer
maturity, higher-yielding bonds, and then paid out income to preferred
shareholders at a short-term rate influenced by the federal funds rate -- the
overnight rate at which banks lend each other money. While leveraged positions
provided the fund an income advantage over its non-leveraged peers, the payout
rate to preferred shareholders rose as the federal funds rate increased, which
reduced the total income earned by the fund over the past 12 months.

Looking ahead

We believe economic growth next year to be moderate. Although there are pockets
of inflationary pressure, such as in education and health care, we generally
expect inflation to remain muted. It may be difficult for businesses

Sector and quality breakdowns are calculated as a percentage of total
investments and net assets, respectively. Ratings shown in the quality
breakdowns represent the rating assigned to a particular bond by one of the
following nationally recognized rating agencies: Standard & Poor's, a division
of The McGraw-Hill Companies, Inc., Moody's Investors Service, Inc. or Fitch
Ratings, Ltd. Ratings are relative and subjective and are not absolute
standards of quality. The fund's credit quality does not remove market risk.

Because the fund is actively managed, there is no guarantee that the fund will
continue to invest in these sectors or maintain these quality breakdowns in the
future.

to find ways to pass on higher costs because of global market pressures, such
as labor competition, high productivity and technology advances. Also, a
significant amount of global cash is invested in US assets. Foreign support for
the US Treasury market, especially, could help keep US interest rates
relatively low.

Against this backdrop, we will likely continue to focus on bonds with good call
protection in maturities that offer a high potential for good return, typically
around 20 years. However, we plan to continue to monitor economic data. If
inflation accelerates, our outlook could change and we would alter our
investment focus accordingly.

Shares of closed-end funds frequently trade at a discount to net asset value.
The price of the fund's shares is determined by a number of factors, several of
which are beyond the control of the fund. Therefore, the fund cannot predict
whether its shares will trade at, below or above net asset value.

Investing in fixed-income securities may involve certain risks, including the
credit quality of individual issuers, possible prepayments, market or economic
developments and yield and share price fluctuations due to changes in interest
rates.

Tax-exempt investing offers current tax-exempt income, but it also involves
special risks. The value of the fund will be affected by interest rate changes
and the creditworthiness of issues held in the fund. When interest rates go up,
bond prices generally drop and vice versa. Interest income from certain
tax-exempt bonds may be subject to certain state and local taxes and, if
applicable, the alternative minimum tax. Capital gains are not exempt from
income taxes.

Investing in high-yield or "junk" bonds offers the potential for higher income
than investments in investment-grade bonds, but also has a higher degree of
risk. Changes in economic conditions or other circumstances may adversely
affect a high-yield bond issuer's ability to make timely principal and interest
payments.

          NOTES TO FINANCIAL STATEMENTS

          November 30, 2005

NOTE 1. ORGANIZATION

Colonial Insured Municipal Fund (the "Fund") is a Massachusetts business trust
registered under the Investment Company Act of 1940 (the "Act"), as amended, as
a non-diversified, closed-end management investment company.

INVESTMENT GOAL

The Fund seeks to provide current income generally exempt from ordinary federal
income tax.

FUND SHARES

The Fund may issue an unlimited number of common shares. On December 20, 1999,
the Fund issued 1,492 Auction Preferred Shares ("APS").

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America ("GAAP") requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities, the disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements.

SECURITY VALUATION

Debt securities generally are valued by pricing services approved by the Fund's
Board of Trustees, based upon market transactions for normal,
institutional-size trading units of similar securities. The services may use
various pricing techniques which take into account appropriate factors such as
yield, quality, coupon rate, maturity, type of issue, trading characteristics
and other data, as well as broker quotes. Debt securities for which quotations
are readily available are valued at an over-the-counter or exchange bid
quotation. Certain debt securities, which tend to be more thinly traded and of
lesser quality, are priced based on fundamental analysis of the financial
condition of the issuer and the estimated value of any collateral. Valuations
developed through pricing techniques may vary from the actual amounts realized
upon sale of the securities, and the potential variation may be greater for
those securities valued using fundamental analysis.

Short-term debt obligations maturing within 60 days are valued at amortized
cost, which approximates market value.

Investments in open-end investment companies are valued at net asset value.

Futures contracts are valued at the settlement price established each day by
the board of trade or exchange on which they are traded.

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

SECURITY TRANSACTIONS

Security transactions are accounted for on the trade date. Cost is determined
and gains (losses) are based upon the specific identification method for both
financial statement and federal income tax purposes.

FUTURES CONTRACTS

The Fund may invest in municipal and U.S. Treasury futures contracts. The Fund
will invest in these instruments to hedge against the effects of changes in the
value of portfolio securities due to anticipated changes in interest rates
and/or market conditions, for duration management, or when the transactions are
economically appropriate to the reduction of risk inherent in the management of
the Fund and not for trading purposes. The use of futures contracts involves
certain risks, which include: (1) imperfect correlation between the price
movement of the instruments and the underlying securities, (2) inability to
close out positions due to differing trading hours, or the temporary absence of
a liquid market, for either the instrument or the underlying securities, or
(3) an inaccurate prediction by Columbia Management Advisors, LLC of the future
direction of interest rates. Any of these risks may involve amounts exceeding
the variation margin recorded in the Fund's Statement of Assets and Liabilities
at any given time.

Upon entering into a futures contract, the Fund deposits cash or securities
with the broker in an amount sufficient to meet the initial margin requirement.
Subsequent payments are made or received by the Fund equal to the daily change
in the contract value and are recorded as variation margin receivable or
payable and offset in unrealized gains or losses. The Fund also identifies
portfolio securities as segregated with the custodian in a separate account in
an amount equal to the futures contract. The Fund recognizes a realized gain or
loss when the contract is closed or expires.

                                    [GRAPHIC]


          NOTES TO FINANCIAL STATEMENTS (continued)

          November 30, 2005


INCOME RECOGNITION

Interest income is recorded on the accrual basis. Original issue discount is
accreted to interest income over the life of the security with a corresponding
increase in the cost basis. Premium and discount are amortized and accreted,
respectively, on all debt securities. Dividend income is recorded on the
ex-date.

FEDERAL INCOME TAX STATUS

The Fund intends to qualify each year as a "regulated investment company" under
Subchapter M of the Internal Revenue Code, as amended, and will distribute
substantially all of its taxable or tax-exempt income, if any, for its tax
year, and as such will not be subject to federal income taxes. In addition, the
Fund intends to distribute in each calendar year substantially all of its net
investment income, capital gains and certain other amounts, if any, such that
the Fund should not be subject to federal excise tax. Therefore, no federal
income or excise tax provision is recorded.

DISTRIBUTIONS TO SHAREHOLDERS

Distributions to common shareholders are recorded on the ex-date. Distributions
to Auction Preferred shareholders are recorded daily and payable at the end of
each dividend period. Each dividend payment period for the APS is generally
seven days. The applicable dividend rate for the APS on November 30, 2005, was
2.91%. For the year ended November 30, 2005, the Fund declared dividends to
Auction Preferred shareholders amounting to $785,610, representing an average
dividend rate of 2.11% per APS.

NOTE 3. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are
determined in accordance with income tax regulations, which may differ from
GAAP. Reclassifications are made to the Fund's capital accounts for permanent
tax differences to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

For the year ended November 30, 2005, permanent book and tax basis differences
resulting primarily from differing treatments for discount accretion/premium
amortization on debt securities were identified and reclassified among the
components of the Fund's net assets as follows:



                UNDISTRIBUTED        ACCUMULATED
            NET INVESTMENT INCOME NET REALIZED LOSS PAID-IN CAPITAL
            --------------------- ----------------- ---------------
                                              
                  $(26,557)......      $26,557            $--


Net investment income and net realized gains, as disclosed on the Statement of
Operations, and net assets were not affected by this reclassification.

The tax character of distributions paid during the years ended November 30,
2005 and November 30, 2004 was as follows:



                                       NOVEMBER 30,   NOVEMBER 30,
                                          2005           2004
                                      ------------   ------------
                                               
             Distributions paid from:
                Tax-Exempt Income      $4,445,195     $4,691,126
                Ordinary Income                --         24,484

                  Capital Gains                --             --


As of November 30, 2005, the components of distributable earnings on a tax
basis were as follows:



            UNDISTRIBUTED UNDISTRIBUTED UNDISTRIBUTED      NET
             TAX-EXEMPT     ORDINARY      LONG-TERM    UNREALIZED
               INCOME        INCOME     CAPITAL GAINS APPRECIATION*
            ------------- ------------- ------------- -------------
                                             
              $272,068         $--           $--       $3,872,153


*  The differences between book-basis and tax-basis net unrealized appreciation
   are primarily due to discount accretion/premium amortization on debt
   securities.

Unrealized appreciation and depreciation at November 30, 2005, based on cost of
investments for federal income tax purposes, was:

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

INVESTMENT ADVISORY FEE

Columbia Management Advisors, LLC ("Columbia"), an indirect wholly owned
subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to
the Fund and provides administrative and other services to the Fund. Prior to
September 30, 2005, Columbia Management Advisors, Inc. was the investment
advisor to


                                                                           12

          NOTES TO FINANCIAL STATEMENTS (continued)

          November 30, 2005

the Fund under the same fee structure. On September 30, 2005, Columbia
Management Advisors, Inc. merged into Banc of America Capital Management, LLC.
At that time, the investment advisor was then renamed Columbia Management
Advisors, LLC. Columbia receives a monthly investment advisory fee at the
annual rate of 0.65% of the Fund's average weekly net assets, including assets
applicable to the APS.

Columbia has contractually agreed to waive a portion of investment advisory fee
for the years ending November 30, 2006, 2007, 2008 and 2009 so that the Fund's
investment advisory fee will not exceed the annual rates of 0.45%, 0.50%, 0.55%
and 0.60%, respectively.

For the year ended November 30, 2005, the Fund's effective investment advisory
fee rate was 0.40%.

PRICING AND BOOKKEEPING FEES

Columbia is responsible for providing pricing and bookkeeping services to the
Fund under a pricing and bookkeeping agreement. Under a separate agreement (the
"Outsourcing Agreement"), Columbia has delegated those functions to State
Street Corporation ("State Street"). As a result, the total fees payable under
the pricing and bookkeeping agreement are paid to State Street.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives an
annual fee of $38,000 paid monthly plus an additional monthly fee based on the
level of average weekly net assets for the month; provided that during any
12-month period, the aggregate fee shall not exceed $140,000.

Prior to November 1, 2005, Columbia received from the Fund an annual fee of
$10,000 paid monthly, and in any month that the Fund's average weekly net
assets exceeded $50 million, an additional monthly fee, calculated by taking
into account the fees payable to State Street under the Outsourcing Agreement.

The Fund also reimburses Columbia and State Street for out-of pocket expenses
and charges, including fees payable to third parties for pricing the Fund's
portfolio securities and direct internal costs incurred by Columbia in
connection with providing Fund accounting oversight and monitoring and certain
other services. For the year ended November 30, 2005, the Fund's effective
pricing and bookkeeping rate, inclusive of out-of-pocket expenses, was 0.066%.

FEE WAIVERS

Columbia has voluntarily agreed to reimburse the Fund for certain expenses so
that total expenses (exclusive of investment advisory fees, brokerage
commissions, interest, taxes and extraordinary expenses, if any) will not
exceed 0.20% annually of the Fund's average weekly net assets, including assets
applicable to APS. Columbia, at its discretion, may revise or discontinue this
arrangement any time.

CUSTODY CREDITS

The Fund has an agreement with its custodian bank under which custody fees may
be reduced by balance credits. These credits are recorded as a reduction of
total expenses on the Statement of Operations. The Fund could have invested a
portion of the assets utilized in connection with the expense offset
arrangement in an income-producing asset if it had not entered into such an
agreement.

FEES PAID TO OFFICERS AND TRUSTEES

All officers of the Fund, with the exception of the Fund's Chief Compliance
Officer, are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees has appointed a Chief
Compliance Officer to the Fund in accordance with federal securities
regulations. The Fund, along with other affiliated funds, pays its pro-rata
share of the expenses associated with the Chief Compliance Officer. The Fund's
expenses for the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may
be terminated at any time. Obligations of the plan will be paid solely out of
the Fund's assets.

OTHER

Columbia provides certain services to the Fund related to Sarbanes-Oxley
compliance. For the year ended November 30, 2005, the Fund paid $1,562 to
Columbia for such services. This amount is included in "Other expenses" on the
Statement of Operations.

NOTE 5. PORTFOLIO INFORMATION

For the year ended November 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $31,166,781 and
$31,891,669, respectively.

NOTE 6. PREFERRED SHARES

The Fund currently has outstanding 1,492 APS. The APS are redeemable at the
option of the Fund on any dividend payment date at the redemption price of
$25,000 per share, plus an amount equal to any dividends accumulated on a daily
basis unpaid through the redemption date (whether or not such dividends have
been declared).

Under the Act, the Fund is required to maintain asset coverage of at least 200%
with respect to the APS as of the last business day of each month in which any
APS are

outstanding. Additionally, the Fund is required to meet more stringent asset
coverage requirements under the terms of the APS Agreement and in accordance
with the guidelines prescribed by the APS' rating agencies. Should these
requirements not be met, or should dividends accrued on the APS not be paid,
the Fund may be restricted in its ability to declare dividends to common
shareholders or may be required to redeem certain APS. At November 30, 2005,
there were no such restrictions on the Fund.

NOTE 7. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

CONCENTRATION OF CREDIT RISK

The Fund holds investments that are insured by private insurers who guarantee
the payment of principal and interest in the event of default or that are
supported by a letter of credit. Each of the Fund's insurers is rated Aaa by
Moody's Investor Services, Inc., except for Radian Asset Assurance, Inc., which
is rated Aa3. At November 30, 2005, private insurers who insure greater than 5%
of the total investments of the Fund were as follows:



                                                    % OF TOTAL
                                                    INVESTMENTS
                 INSURER                            (UNAUDITED)
                 ----------------------------------------------
                                                 
                 AMBAC Assurance Corp.                 34.1%
                 MBIA Insurance Corp.                  26.8
                 Financial Security Assurance, Inc.    15.0
                 Financial Guaranty Insurance Co.       8.5


GEOGRAPHIC CONCENTRATION

The Fund has greater than 5% of its total investments at November 30, 2005
invested in debt obligations issued by the states of California, Massachusetts,
New York, Texas and the Commonwealth of Puerto Rico and their respective
political subdivisions, agencies and public authorities. The Fund is more
susceptible to economic and political factors adversely affecting issuers of
the specific state's municipal securities than are municipal bond funds that
are not concentrated to the same extent in these issuers.

HIGH-YIELD SECURITIES

Investing in high-yield securities may involve greater credit risk and
considerations not typically associated with investing in U.S. government bonds
and other higher quality fixed income securities. These securities are
non-investment grade securities, often referred to as "junk" bonds. Economic
downturns may disrupt the high yield market and impair the ability of issuers
to repay principal and interest. Also, an increase in interest rates would
likely have an adverse impact on the value of such obligations. Moreover,
high-yield securities may be less liquid to the extent that there is no
established secondary market.

ISSUER FOCUS

As a non-diversified fund, the Fund may invest a greater percentage of its
total assets in the securities of fewer issuers than a diversified fund. The
Fund may, therefore, have a greater risk of loss from a few issuers than a
similar fund that invests more broadly.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged
into Banc of America Capital Management, LLC (now named Columbia Management
Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has
been renamed Columbia Management Distributors, Inc.) (the "Distributor")
(collectively, the "Columbia Group") entered into an Assurance of
Discontinuance with the New York Attorney General ("NYAG") (the "NYAG
Settlement") and consented to the entry of a cease-and-desist order by the
Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and
the NYAG Settlement are referred to collectively as the "Settlements". The
Settlements contain substantially the same terms and conditions as outlined in
the agreements in principle which Columbia Group entered into with the SEC and
NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution
consultant (see below). The Columbia Funds have also voluntarily undertaken to
implement certain governance measures designed to maintain the independence of
their boards of trustees. The NYAG Settlement also, among other things,
requires Columbia and its affiliates to reduce certain Columbia Funds
(including the former Nations Funds) and other mutual funds management fees
collectively by $32 million per year for five years, for a projected total of
$160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution


                                                                           14

          NOTES TO FINANCIAL STATEMENTS (CONTINUED)

consultant, who is acceptable to the SEC staff and the Columbia Funds'
independent trustees. The distribution plan must be based on a methodology
developed in consultation with the Columbia Group and the funds' independent
trustees and not unacceptable to the staff of the SEC. At this time, the
distribution plan is still under development. As such, any gain to the funds or
their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments
resulting from them, the market price of fund shares could decline.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov.
A copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have
filed suit against certain funds, the Trustees of the Columbia Funds,
FleetBoston Financial Corporation and its affiliated entities and/or Bank of
America and its affiliated entities. More than 300 cases including those filed
against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America and
its affiliated entities have been transferred to the Federal District Court in
Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity
and seek, among other things, the removal of the trustees of the Columbia
Funds, removal of the Columbia Group, disgorgement of all management fees and
monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in
Massachusetts state court alleging that the conduct, including market timing,
entitles Class B shareholders in certain Columbia Funds to an exemption from
contingent deferred sales charges upon early redemption ("the CDSC Lawsuit").
The CDSC Lawsuit has been removed to federal court in Massachusetts and the
federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this
litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers
and affiliated entities were named as defendants in certain purported
shareholder class and derivative actions making claims, including claims under
the Investment Company and the Investment Advisers Acts of 1940 and state law.
The suits allege, inter alia, that the fees and expenses paid by the funds are
excessive and that the advisers and their affiliates inappropriately used fund
assets to distribute the funds and for other improper purposes. On March 2,
2005, the actions were consolidated in the Massachusetts federal court as In re
Columbia Entities Litigation. The plaintiffs filed a consolidated amended
complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims
by plaintiffs and ordered that the case be closed. The plaintiffs filed a
notice of appeal on December 30, 2005.

(a)The Fund commenced investment operations on October 29, 1999. Per share data
   and total return reflect activity from that date.
(b)Per share data was calculated using average shares outstanding during the
   period.
(c)Effective December 1, 2001, the Fund adopted the provision of the AICPA
   Audit and Accounting Guide for Investment Companies and began accreting
   market discount on all debt securities. The effect of this change for the
   year ended November 30, 2002 was to increase the ratio of net investment
   income to average net assets from 8.02% to 8.04% and increase the ratio of
   net investment income (adjusted for dividend payments to preferred
   shareholders) from 7.20% to 7.22%. The impact to the net investment income
   and net realized and unrealized loss per share was less than $0.01. Per
   share data and ratios for periods prior to November 30, 2002 have not been
   restated to reflect this change in presentation.
(d)The per share net investment income amount does not reflect the period's
   reclassification of differences between book and tax basis net investment
   income.

      REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


TO THE TRUSTEES AND THE SHAREHOLDERS OF COLONIAL INSURED MUNICIPAL FUND

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Colonial Insured Municipal Fund
(the "Fund") at November 30, 2005, and the results of its operations, the
changes in its net assets and its financial highlights for the periods
indicated, in conformity with accounting principles generally accepted in the
United States of America. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements 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 are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits, which included confirmation
of securities at November 30, 2005 by correspondence with the custodian and
brokers, provide a reasonable basis for our opinion.

          DIVIDEND REINVESTMENT PLAN


COLONIAL INSURED MUNICIPAL FUND

Pursuant to the Fund's Dividend Reinvestment Plan (the "Plan"), all Common
Shareholders whose shares are registered in their own names will have all
distributions reinvested automatically in additional Common Shares of the Fund
by Computershare (the "Plan Agent"), as agent under the Plan, unless a Common
Shareholder elects to receive cash. An election to receive cash may be revoked
or reinstated at the option of the Common Shareholder. Shareholders whose
shares are held in the name of a broker or nominee will have distributions
reinvested automatically by the broker or nominee in additional shares under
the Plan, unless the service is not provided by the broker or nominee, or
unless the shareholder elects to receive distributions in cash. If the service
is not available, such distributions will be paid in cash. Shareholders whose
shares are held in the name of a broker or nominee should contact the broker or
nominee for details. All distributions to investors who elect not to
participate (or whose broker or nominee elects not to participate) in the Plan
will be paid by check mailed directly to the record holder by the Plan Agent,
as dividend paying agent.

The Plan Agent will furnish each person who buys shares in the offering with
written information relating to the Plan. Included in such information will be
procedures for electing to receive distributions in cash (or, in the case of
shares held in the name of a broker or nominee who does not participate in the
Plan, procedures for having such shares registered in the name of the
shareholder so that such shareholder may participate in the Plan).

If the Trustees of the Fund declare a dividend (including a capital gain
dividend) payable either in shares or in cash, as holders of shares may have
elected, then nonparticipants in the Plan will receive cash and participants in
the Plan will receive the equivalent in shares valued as set forth below.
Whenever a market price is equal to or exceeds net asset value at the time
shares are valued for the purpose of determining the number of shares
equivalent to the distribution, participants will be issued shares at the net
asset value most recently determined as provided under "Net Asset Value" in the
Fund's prospectus and its Statement of Additional Information, but in no event
less than 95% of the market price. If the net asset value of the shares at such
time exceeds the market price of shares at such time, or if the Fund should
declare a dividend (including a capital gain dividend) payable only in cash,
the Plan Agent will, as agent for the participants, use the cash that the
shareholders would have received as a dividend to buy shares in the open
market, the American Stock Exchange or elsewhere, for the participants'
accounts. If, before the Plan Agent has completed its purchases, the market
price exceeds the net asset value of the shares, the average per share purchase
price paid by the Plan Agent may exceed the net asset value of the shares,
resulting in the acquisition of fewer shares than if the dividend (including a
capital gain dividend) had been paid in shares issued by the Fund. The Plan
Agent will apply all cash received as a dividend (including a capital gain
dividend) to purchase shares on the open market as soon as practicable after
the payment date of such dividend, but in no event later than 30 days after
such date, except where necessary to comply with applicable provisions of the
federal securities laws.

There is no charge to participants for reinvesting dividends (including capital
gain dividends). The Plan Agent's fees for handling the reinvestment of
dividends (including capital gain dividends) will be paid by the Fund. There
will be no brokerage charges with respect to shares issued directly by the Fund
as a result of dividends or capital gains distributions payable either in stock
or in cash. However, each participant will pay a pro rata share of brokerage
commissions incurred with respect to the Plan Agent's open market purchases in
connection with the reinvestment of dividends (including capital gain
dividends).

The automatic reinvestment of dividends (including capital gain dividends) will
not relieve participants of any income tax which may be payable on such
dividends. The amount of the dividend for tax purposes may vary depending on
whether the Fund issues new Common Shares or purchases them on the open market.

The Plan may be amended or terminated on 30 days' written notice to Plan
participants. All correspondence concerning the Plan should be directed to
Computershare by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone
at 1-800-730-6001.

          BOARD CONSIDERATION AND APPROVAL OF INVESTMENT ADVISORY AGREEMENTS


The Advisory Fees and Expenses Committee of the Board of Trustees meets one or
more times annually, usually in late summer, to review the advisory agreements
(collectively, the "Agreements") of the funds for which the Trustees serve as
trustees or directors (each a "fund") and determine whether to recommend that
the full Board approve the continuation of the Agreements for an additional
one-year period. After the Committee has made its recommendation, the full
Board, including the Independent Trustees, determines whether to approve the
continuation of the Agreements. In addition, the Board, including the
Independent Trustees, considers matters bearing on the Agreements at most of
its other meetings throughout the year and meets regularly with the heads of
each investment area within Columbia. The Trustees also meet with selected fund
portfolio managers at various times throughout the year. The Trustees receive
and review all materials that they, their legal counsel or Columbia, the funds'
investment adviser, believe to be reasonably necessary for the Trustees to
evaluate the Agreements and determine whether to approve the continuation of
the Agreements. Those materials generally include, among other items, (i)
information on the investment performance of each fund relative to the
performance of peer groups of mutual funds and the fund's performance
benchmarks, (ii) information on each fund's advisory fees and other expenses,
including information comparing the fund's expenses to those of peer groups of
mutual funds and information about any applicable expense caps and fee
"breakpoints," (iii) sales and redemption data, (iv) information about the
profitability of the Agreements to Columbia, and potential "fall-out" or
ancillary benefits that Columbia and its affiliates may receive as a result of
their relationships with the funds and (v) information obtained through
Columbia's response to a questionnaire prepared at the request of the Trustees
by counsel to the funds and independent legal counsel to the Independent
Trustees. The Trustees also consider other information such as (vi) Columbia's
financial results and financial condition, (vii) each fund's investment
objective and strategies and the size, education and experience of Columbia's
investment staffs and their use of technology, external research and trading
cost measurement tools, (viii) the allocation of the funds' brokerage, if any,
including allocations to brokers affiliated with Columbia and the use of "soft"
commission dollars to pay fund expenses and to pay for research products and
services, (ix) Columbia's resources devoted to, and its record of compliance
with, the funds' investment policies and restrictions, policies on personal
securities transactions and other compliance policies, (x) Columbia's response
to various legal and regulatory proceedings since 2003 and (xi) the economic
outlook generally and for the mutual fund industry in particular. In addition,
the Trustees confer with their independent fee consultant and review materials
relating to the Agreements that the independent fee consultant provides.
Throughout the process, the Trustees have the opportunity to ask questions of
and request additional materials from Columbia and to consult independent legal
counsel to the Independent Trustees.

The Board of Trustees most recently approved the continuation of the Agreements
at its October, 2005 meeting, following meetings of the Advisory Fees and
Expenses Committee held in August, September, and October, 2005. In considering
whether to approve the continuation of the Agreements, the Trustees, including
the Independent Trustees, did not identify any single factor as determinative,
and each weighed various factors as he or she deemed appropriate. The Trustees
considered the following matters in connection with their approval of the
continuation of the Agreements: The nature, extent and quality of the services
provided to the funds under the Agreements. The Trustees considered the nature,
extent and quality of the services provided by Columbia and its affiliates to
the funds and the resources dedicated to the funds by Columbia and its
affiliates. Among other things, the Trustees considered (i) Columbia's ability,
including its resources, compensation programs for personnel involved in fund
management, reputation and other attributes, to attract and retain highly
qualified research, advisory and supervisory investment professionals; (ii) the
portfolio management services provided by those investment professionals; and
(iii) the trade execution services provided on behalf of the funds. For each
fund, the Trustees also considered the benefits to shareholders of investing in
a mutual fund that is part of a family of funds offering exposure to a variety
of asset classes and investment disciplines and providing for a variety of fund
and shareholder services. After reviewing those and related factors, the
Trustees concluded, within the context of their overall conclusions regarding
each of the Agreements, that the nature, extent and quality of services
provided supported the continuation of the Agreements. Investment performance
of the funds and Columbia. The Trustees reviewed information about the
performance of each fund over various time periods, including information
prepared by an independent third party that compared the performance of each
fund to the performance of peer groups of mutual funds and performance
benchmarks. The Trustees also reviewed a description of the third party's
methodology for identifying each fund's peer group for purposes of performance
and expense comparisons. The Trustees also considered additional information
that the


                                                                           24

          BOARD CONSIDERATION AND APPROVAL OF INVESTMENT ADVISORY AGREEMENTS


Advisory Fees and Expenses Committee requested from Columbia relating to funds
that presented relatively weaker performance and/or relatively higher expenses.
In the case of each fund that had performance that lagged that of a relevant
peer group for certain (although not necessarily all) periods, the Trustees
concluded that other factors relevant to performance were sufficient, in light
of other considerations, to warrant continuation of the fund's Agreements.
Those factors varied from fund to fund, but included one or more of the
following: (i) that the fund's performance, although lagging in certain recent
periods, was stronger over the longer term; (ii) that the underperformance was
attributable, to a significant extent, to investment decisions that were
reasonable and consistent with the fund's investment strategy and policies and
that the fund was performing as expected, given market conditions and the
fund's investment strategy; (iii) that the fund's performance was competitive
when compared to other relevant performance benchmarks or peer groups; (iv)
that Columbia had taken or was taking steps designed to help improve the fund's
investment performance, including, but not limited to, replacing portfolio
managers or modifying investment strategies; (v) that the fund's advisory fee
had recently been, or was proposed to be, reduced, with the goal of helping the
fund's net return to shareholders become more competitive; and (vi) that other
fund expenses, such as transfer agency or fund accounting fees, have recently
been reduced, with the goal of helping the fund's net return to shareholders
become more competitive. The Trustees also considered Columbia's performance
and reputation generally, the funds' performance as a fund family generally,
and Columbia's historical responsiveness to Trustee concerns about performance
and Columbia's willingness to take steps intended to improve performance. After
reviewing those and related factors, the Trustees concluded, within the context
of their overall conclusions regarding each of the Agreements, that the
performance of each fund and Columbia was sufficient, in light of other
considerations, to warrant the continuation of the Agreements. The costs of the
services provided and profits realized by Columbia and its affiliates from
their relationships with the funds. The Trustees considered the fees charged to
the funds for advisory services as well as the total expense levels of the
funds. That information included comparisons (provided both by management and
by an independent third party) of the funds' advisory fees and total expense
levels to those of their peer groups and information about the advisory fees
charged by Columbia to comparable accounts. In considering the fees charged to
comparable accounts, the Trustees took into account, among other things,
management's representations about the differences between managing mutual
funds as compared to other types of accounts, including the additional
resources required to effectively manage mutual funds and distribute mutual
fund shares. In evaluating each fund's advisory fees, the Trustees also took
into account the demands, complexity and quality of the investment management
of the fund. The Trustees considered reductions in advisory fee rates,
implementation of advisory fee breakpoints, institution of advisory fee
waivers, and changes to expense caps, which benefited a number of the funds.
Furthermore, the Trustees considered the projected impact on expenses resulting
from the overall cost reductions that management anticipated would result from
the shift to a common group of service providers for transfer agency, fund
accounting and custody services for mutual funds advised by Bank of America
affiliates. The Trustees also noted management's stated justification for the
fees charged to the funds, which included information about the performance of
the funds, the services provided to the funds and management's view as to why
it was appropriate that some funds bear advisory fees or total expenses greater
than their peer group medians. The Trustees also considered the compensation
directly or indirectly received by Columbia and its affiliates from their
relationships with the funds. The Trustees reviewed information provided by
management as to the profitability to Columbia and its affiliates of their
relationships with the funds, and information about the allocation of expenses
used to calculate profitability. When reviewing profitability, the Trustees
also considered court cases in which adviser profitability was an issue in
whole or in part, the performance of the relevant funds, the expense levels of
the funds, and whether Columbia had implemented breakpoints and/or expense caps
with respect to the funds.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
advisory fees charged to each of the funds were fair and reasonable, and that
the costs of the advisory services generally, and the related profitability to
Columbia and its affiliates of their relationships with the funds, supported
the continuation of the Agreements.

Economies of Scale. The Trustees considered the existence of any economies of
scale in the provision of services by Columbia to each fund and whether those
economies were shared with the fund through breakpoints in the investment
advisory fees or other means, such as expense waivers. The Trustees noted that
many of the funds benefited from breakpoints, expense caps, or both. In
considering those issues, the Trustees also took note of the costs of the

          BOARD CONSIDERATION AND APPROVAL OF INVESTMENT ADVISORY AGREEMENTS


services provided (both on an absolute and a relative basis) and the
profitability to Columbia and its affiliates of their relationships with the
funds, as discussed above. After reviewing those and related factors, the
Trustees concluded, within the context of their overall conclusions regarding
each of the Agreements, that the extent to which economies of scale were shared
with the funds supported the continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but
were not limited to the following:

..   the extent to which each fund had operated in accordance with its
    investment objective and its record of compliance with its investment
    restrictions, and the compliance programs of the funds and Columbia. They
    also considered the compliance-related resources that Columbia and its
    affiliates were providing to the funds.
..   the nature, quality, cost and extent of administrative and shareholder
    services performed by Columbia and its affiliates, both under the
    Agreements and under separate agreements for the provision of transfer
    agency and administrative services.
..   so-called "fall-out benefits" to Columbia, such as the engagement of its
    affiliates to provide distribution, brokerage and transfer agency services
    to the funds, and the benefits of research made available to Columbia by
    reason of brokerage commissions generated by the funds' securities
    transactions, as well as possible conflicts of interest associated with
    those fall-out and other benefits, and the reporting, disclosure and other
    processes in place to disclose and monitor those possible conflicts of
    interest.
..   the draft report provided by the independent fee consultant, which included
    information about and analysis of the funds' fees, expenses and performance.

Based on their evaluation of all factors that they deemed to be material,
including those factors described above, and assisted by the advice of
independent counsel and the independent fee consultant, the Trustees, including
the Independent Trustees, approved the continuance of each of the Agreements
through November 30, 2006.

          SUMMARY OF MANAGEMENT FEE EVALUATION BY INDEPENDENT FEE CONSULTANT


                   Prepared Pursuant to the February 9, 2005
                          Assurance of Discontinuance
                             between the Office of
                    Attorney General of New York State and
                    Columbia Management Advisors, Inc. and
                       Columbia Funds Distributor, Inc.

                               October 11, 2005

I. Overview

Columbia Management Advisors, Inc. ("CMA") and Columbia Funds Distributors,
Inc. ("CFD") (CFD together with CMA referred to herein as Columbia Management
Group or "CMG/1/"), entered into an agreement with the New York Attorney
General's Office in the form of an Assurance of Discontinuance (the "AOD"). The
AOD stipulated that CMA would be permitted to manage or advise the Columbia
Funds only if the Independent Members (as such term is defined in the AOD) of
the Columbia Funds' Board of Trustees/Directors (collectively the "Trustees")
appointed a Senior Officer or an Independent Fee Consultant ("IFC") who, among
other things, is to manage the process by which management fees are negotiated.
On May 15, 2005, the Independent Members of the Board appointed me as the IFC
for the Columbia Funds. This report is the annual written evaluation of the
Columbia Funds for 2005 that I have prepared in my capacity as IFC, as required
by the AOD.

A. Duties of the Independent Fee Consultant

As part of the AOD, the Independent Members of the Columbia Funds' Board of
Trustees/Directors agreed to retain an independent fee consultant who was to
participate in the management fee negotiation process. The IFC is charged with
"... duties and responsibilities [that] include managing the process by which
proposed management fees (including, but not limited to, advisory fees) to be
charged the Columbia Fund[s] are negotiated so that they are negotiated in a
manner which is at arms length and reasonable and consistent with this
Assurance of Discontinuance." However, the IFC does not replace the Trustees in
their role of negotiating management and other fees with CMG and its
affiliates. In particular, the AOD states that "Columbia Advisors may manage or
advise a Columbia Fund only if the reasonableness of the proposed management
fees is determined by the Board of Trustees of the Columbia Fund using ... an
annual independent written evaluation prepared by or under the direction of the
.... Independent Fee Consultant...." This report, pursuant to the AOD,
constitutes the "annual independent written evaluation prepared by or under the
direction of the... Independent Fee Consultant."

The AOD requires the IFC report to consider at least the following:

a) Management fees (including any components thereof) charged by other mutual
fund companies for like services;

b) Management fees (including any components thereof) charged to institutional
and other clients of CMA for like services;

c) Costs to CMA and its affiliates of supplying services pursuant to the
management fee agreements, excluding any intra-corporate profit;

d) Profit margins of CMA and its affiliates from supplying such services;

e) Possible economies of scale as the CMA fund grows larger; and

f) The nature and quality of CMA services, including Columbia Funds'
performance.

This report is designed to assist the Board in evaluating the 2005 contract
renewal for Columbia Funds. In addition, this report points out areas where the
Board may deem additional information and analysis to be appropriate over time.

B. Sources of Information Used in My Evaluation

I have requested data from CMG and various third party industry data sources or
independent research companies that work in the mutual fund arena. The
following list generally describes the types of information I requested.

1. I collected data on performance, management fees, and expense ratios of both
Columbia Funds and comparable non-Columbia Funds. The sources of this
information were CMG, Lipper Inc. ("Lipper") and Morningstar Inc.
("Morningstar"). While Lipper and Morningstar each selected a different group
of peer funds it deemed appropriate against which to measure the relative
performance and fees of Columbia Funds, I conducted an independent review of
the appropriateness of each peer group.

/1/Prior to the date of this report, CMA merged into an affiliated entity, Banc
   of America Capital Management, LLC ("BACAP"), and BACAP then changed its
   name to Columbia Management Advisors, LLC which carries on the business of
   CMA, and CFD changed its name to Columbia Management Distributors, Inc.

          SUMMARY OF MANAGEMENT FEE EVALUATION BY INDEPENDENT FEE CONSULTANT



2. I reviewed data on CMG's expense and profitability that I obtained from CMA
directly.

3. I have reviewed data on the organizational structure of CMG in general.

4. I collected information on profitability from Strategic Insight Mutual Fund
Research and Consulting, LLC ("Strategic Insight"). I used this third-party
independent research as an additional method to gauge the accuracy of the data
collected in (2) above.

5. I conducted interviews with various CMG staff, including members of the
senior management team, legal staff, heads of affiliates, portfolio managers,
and financial personnel.

6. I reviewed current 2005 Section 15(c) material provided to the Board and
material presented to the Board in the 2004 fee and performance evaluation.

7. I have reviewed various academic research papers, industry publications, and
other available literature dealing with mutual fund operations, profitability,
and other issues. In addition, I have reviewed SEC releases and studies of
mutual fund expenses.

8. I have reviewed documents pertaining to recent mutual fund litigation in
general and publicly available information about litigation where CMG has been
involved.

In addition, I have engaged NERA Economic Consulting ("NERA") and independent
consultant Dr. John Rea to assist me in data management and analysis. Both NERA
and Dr. Rea have extensive experience in the mutual fund industry through
consulting, government positions, or industry trade groups that provide unique
insights and special knowledge pertaining to my independent analysis of fees,
performance, and profitability. I have also retained Shearman & Sterling LLP as
outside counsel to advise me in connection with my review.

C. Qualifications and Independence

I am the Walter H. Carpenter Chair and Professor of Finance at Babson College.
Before this I was the Chief Economist of the U.S. Securities and Exchange
Commission. I have no material relationship with Bank of America or CMG aside
from acting as IFC, and am aware of no relationship with any of their
affiliates. [Resume omitted]

II. Evaluation of the General Process Used to Negotiate the Advisory Contract

A. General Considerations

My analysis considered all factors and information I reviewed on the finances
and operations of Columbia Funds. I gave each factor an appropriate weight in
my overall findings, and no single factor was in itself the sole criterion for
a finding or conclusion. My objective was to assess all of the information
provided and conduct a robust evaluation of Columbia Funds' operations, fees,
and performance.

My analysis and thought processes will and, I believe, should, differ in
certain ways from the processes used by Trustees in their evaluation of the
management agreements. In particular, because of my technical and quantitative
background, I may use techniques and data that Trustees have not previously
felt would be useful. I view this supplemental analysis as appropriate because
my role is to assist Trustees in their decisions, and to the extent that I
bring new ideas or analysis to the evaluation, I believe this improves the
process by which management fees for the Columbia Funds may be negotiated in
accordance with the AOD.

Finally, as part of my role as IFC, I have, from time to time, sent to Trustees
additional papers and reports produced by third parties that I felt had bearing
on the fee negotiation process. I viewed these materials as educational in
nature and felt they would aid Trustees in placing their work in context.

B. CMG Management Interviews

As a starting point of my analysis, I have met with members of CMG staff to
gain an understanding of the organizational structure and personnel involved in
running the Columbia fund family.

I have had general discussions and have received information about the
management structure of CMG. My conversations with management have been
informative. In addition, I have participated in Board meetings where Trustees
and management have discussed issues relating to management agreements and
performance of Columbia Funds. When I felt it was appropriate, I added my
opinions on particular matters, such as fund performance or fee levels, to the
discussion.

C. Trustees' Fee and Performance Evaluation Process

After making initial requests for information, members of the Trustees of the
Columbia Funds met in advance of the October Section 15(c) contract approval
meeting to review certain fee, performance and other data for the Columbia
Funds and to ask questions and make requests of management. Trustees have
developed a process to evaluate the fee and expense levels and performance of
Columbia Funds.


                                                                           28





                                    [GRAPHIC]


          SUMMARY OF MANAGEMENT FEE EVALUATION BY INDEPENDENT FEE CONSULTANT



This process is used to highlight those funds that have been performing poorly,
may have had higher management fees or expense ratios, or both.

The process involves providing instructions to Lipper to prepare specific data
analyses tailored to the Trustees review framework. These instructions include
highlighting funds that hit one or more fee performance "screens." The six
screens the Trustees use are as follows:

a. 5th Lipper quintile in actual management fee;

b. 5th Lipper quintile in total expense ratio;

c. Three or more 5th Lipper quintile rankings in the 1-, 3-, 5- or 10-year
performance rankings;

d. Sum of the Lipper Quintile Rank (1-year performance) and the Lipper Quintile
Rank (actual management fee) totals a number equal to or higher than 8;

e. Sum of the Lipper Quintile Rank (1-year performance) and the Lipper Quintile
Rank (total expense ratio) totals a number equal to or higher than 8; and

f. Sum of the Lipper Quintile Rank (3-year performance) and the Lipper Quintile
Rank (total expense ratio) totals a number equal to or higher than 8.

If a fund hits one or more of these screens, it is highlighted for additional
review by the Trustees. This method is only used as an aid for Trustees to
highlight funds and is not the sole test of whether the Board will determine to
take particular actions concerning fees or performance. Funds that have not
been flagged by this screen also may be singled out for fee and performance
reasons, and the Trustees may determine not to take action with respect to the
fees or performance of funds that have been flagged by the screen. These
screens contribute to the basis for discussions on Trustees' views on the
Columbia Funds.

III. Findings

My findings based on my work as IFC are as follows:

1. The Trustees have the relevant information necessary to form an opinion on
the reasonableness of fees and evaluate the performance of the Columbia Funds.
The process the Trustees used in preparing to reach their determination has
been open and informative. In my view, the 2005 process by which the management
fees of the Columbia Funds have been negotiated thus far has been, to the
extent practicable, at arm's length and reasonable and consistent with the AOD.

2. Columbia Funds demonstrated a range of performance relative to their peers.
I find that across the fund complex, 54.26 percent of Columbia Funds have
performance higher than the median of their respective Lipper performance
universe, and 42.55 percent of Columbia Funds have performance higher than the
median of their respective Lipper performance group. In addition, Lipper
performance universe and group comparison showed that Columbia Funds were
distributed roughly evenly across these quintiles. The Trustees have worked
with management to address issues of funds that have demonstrated consistent or
significant underperformance.

3. Columbia Funds demonstrate a range of management fees and expense ratios
relative to their peers. I find that across the fund complex, 58.51 percent of
Columbia Funds have expenses below the median of their Lipper expense universe,
and 53.19 percent of Columbia Funds have expenses below the median of their
Lipper expense group. In addition, Lipper expense universe and group
comparisons show that Columbia Funds are distributed roughly evenly across
these quintiles. The Trustees have taken steps to limit shareholder expenses
for certain funds having management fees significantly above their peers, often
though the use of fee waivers to which CMG has agreed.

Consolidation of various funds and fund families managed by CMG has resulted in
substantial savings in non-advisory expenses.

4. Profitability to CMG of the individual funds ranges widely, but the overall
profitability to CMG of its relationship with the Columbia Funds appears to
fall within a reasonable range. The method of cost allocation to funds is
addressed in the material provided by CMG to the Trustees, but additional
information may be necessary to make a judgment on fund level profitability. My
review of profitability and cost allocation is ongoing, and I plan to continue
to develop my views with regard to fund level profitability.

5. Columbia Funds have instituted fee schedules with breakpoints designed to
enable investors to benefit from fund economies of scale, although 71% of the
funds have not yet reached their first breakpoint. My analysis of the
appropriateness of the breakpoint levels, which I expect will take into account
the cost and profitability of the individual funds, is ongoing.

My work is ongoing and my views may develop over time in light of new
information and analysis.

Respectfully submitted,
Erik R. Sirri

(e)(1) Audit Committee Pre-Approval Policies and Procedures

I. General Overview

The Audit Committee of the registrant has adopted a formal policy (the
"Policy") which sets forth the procedures and the conditions pursuant to which
the Audit Committee will pre-approve (i) all audit and non-audit (including
audit related, tax and all other) services provided by the registrant's
independent auditor to the registrant and individual funds



(collectively "Fund Services"), and (ii) all non-audit services provided by the
registrant's independent auditor to the funds' adviser or a control affiliate
of the adviser, that relate directly to the funds' operations and financial
reporting (collectively "Fund-related Adviser Services"). A "control affiliate"
is an entity controlling, controlled by, or under common control with the
adviser that provides ongoing services to the funds, and the term "adviser" is
deemed to exclude any unaffiliated sub-adviser whose role is primarily
portfolio management and is sub-contracted or overseen by another investment
adviser. The adviser and control affiliates are collectively referred to as
"Adviser Entities."

The Audit Committee uses a combination of specific (on a case-by-case basis as
potential services are contemplated) and general (pre-determined list of
permitted services) pre-approvals. Unless a type of service has received
general pre-approval, it will require specific pre-approval by the Audit
Committee if it is to be provided by the independent auditor.

The Policy does not delegate the Audit Committee's responsibilities to
pre-approve services performed by the independent auditor to management.

II. General Procedures

On an annual basis, the Fund Treasurer and/or Director of Trustee
Administration shall submit to the Audit Committee a schedule of the types of
Fund Services and Fund-related Adviser Services that are subject to general
pre-approval.

These schedules will provide a description of each type of service that is
subject to general pre-approval and, where possible, will provide estimated
fees for each instance of providing each service. This general pre-approval and
related fees (where provided) will generally cover a one-year period (for
example, from June 1 through May 31 of the following year). The Audit Committee
will review and approve the types of services and review the projected fees for
the next one-year period and may add to, or subtract from, the list of general
pre-approved services from time to time, based on subsequent determinations.
This approval acknowledges that the Audit Committee is in agreement with the
specific types of services that the independent auditor will be permitted to
perform. The fee amounts will be updated to the extent necessary at other
regularly scheduled meetings of the Audit Committee.

In addition to the fees for each individual service, the Audit Committee has
the authority to implement a fee cap on the aggregate amount of non-audit
services provided to an individual fund.

If, subsequent to general pre-approval, a fund, its investment adviser or a
control affiliate determines that it would like to engage the independent
auditor to perform a service that requires pre-approval and that is not
included in the general pre-approval list, the specific pre-approval procedure
shall be as follows:

  .   A brief written request shall be prepared by management detailing the
      proposed engagement with explanation as to why the work is proposed to be
      performed by the independent auditor;



  .   The request should be addressed to the Audit Committee with copies to the
      Fund Treasurer and/or Director of Trustee Administration;

  .   The Fund Treasurer and/or Director of Trustee Administration will arrange
      for a discussion of the service to be included on the agenda for the next
      regularly scheduled Audit Committee meeting, when the Committee will
      discuss the proposed engagement and approve or deny the request.

  .   If the timing of the project is critical and the project needs to
      commence before the next regularly scheduled meeting, the Chairperson of
      the Audit Committee may approve or deny the request on behalf of the
      Audit Committee, or, in the Chairperson's discretion, determine to call a
      special meeting of the Audit Committee for the purpose of considering the
      proposal. Should the Chairperson of the Audit Committee be unavailable,
      any other member of the Audit Committee may serve as an alternate for the
      purpose of approving or denying the request. Discussion with the
      Chairperson (or alternate, if necessary) will be arranged by the Fund
      Treasurer and/or Director of Trustee Administration. The independent
      auditor will not commence any such project unless and until specific
      approval has been given.

III. Certain Other Services Provided to Adviser Entities

The Audit Committee recognizes that there are cases where services proposed to
be provided by the independent auditor to the adviser or control affiliates are
not Fund-related Adviser Services within the meaning of the Policy, but
nonetheless may be relevant to the Audit Committee's ongoing evaluation of the
auditor's independence and objectivity with respect to its audit services to
the funds. As a result, in all cases where an Adviser Entity engages the
independent auditor to provide audit or non-audit services that are not Fund
Services or Fund-related Adviser Services, were not subject to pre-approval by
the Audit Committee, and the projected fees for any such engagement (or the
aggregate of all such engagements during the period covered by the Policy)
exceeds a pre-determined threshold established by the Audit Committee; the
independent auditor, Fund Treasurer and/or Director of Trustee Administration
will notify the Audit Committee not later than its next meeting. Such
notification shall include a general description of the services provided, the
entity that is to be the recipient of such services, the timing of the
engagement, the entity's reasons for selecting the independent auditor, and the
projected fees. Such information will allow the Audit Committee to consider
whether non-audit services provided to the adviser and Adviser Entities, which
were not subject to Audit Committee pre-approval, are compatible with
maintaining the auditor's independence with respect to the Funds.



IV. Reporting to the Audit Committee

The Fund Treasurer or Director of Trustee Administration shall report to the
Audit Committee at each of its regular meetings regarding all Fund Services or
Fund-related Adviser Services initiated since the last such report was
rendered, including:

  .   A general description of the services, and

  .   Actual billed and projected fees, and

  .   The means by which such Fund Services or Fund-related Adviser Services
      were pre-approved by the Audit Committee.

In addition, the independent auditor shall report to the Audit Committee
annually, and no more than 90 days prior to the filing of audit reports with
the SEC, all non-audit services provided to entities in the funds' "investment
company complex," as defined by SEC rules, that did not require pre-approval
under the Policy.

V. Amendments; Annual Approval by Audit Committee

The Policy may be amended from time to time by the Audit Committee. Prompt
notice of any amendments will be provided to the independent auditor, Fund
Treasurer and Director of Trustee Administration. The Policy shall be reviewed
and approved at least annually by the Audit Committee.

                                     *****

(e)(2) The percentage of services described in paragraphs (b) through (d) of
this Item approved pursuant to the "de minimis" exception under paragraph
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X during both fiscal years ended
November 30, 2005 and November 30, 2004 was zero.

(f) Not applicable.

(g) All non-audit fees billed by the registrant's accountant for services
rendered to the registrant for the fiscal years ended November 30, 2005 and
November 30, 2004 are disclosed in (b) through (d) of this Item.

During the fiscal years ended November 30, 2005 and November 30, 2004, there
were no Audit-Related Fees, Tax Fees or All Other Fees that were approved for
services to the investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser) and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the registrant under
paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.

The percentage of Audit-Related Fees, Tax Fees and All Other Fees required to
be approved under paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X that were
approved under the "de minimis" exception during both fiscal years ended
November 30, 2005 and November 30, 2004 was zero.



(h) The registrant's Audit Committee of the Board of Directors has considered
whether the provision of non-audit services that were rendered to the
registrant's adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X, is compatible with maintaining the principal
accountant's independence. The Audit Committee determined that the provision of
such services is compatible with maintaining the principal accountant's
independence.

Item 5. Audit Committee of Listed Registrants.

The registrant has a separately-designated standing audit committee established
in accordance with Section 3(a)(58)(A) of the Exchange Act (15 U.S.C.
78c(a)(58)(A)). Douglas A. Hacker, Thomas E. Stitzel, Anne-Lee Verville and
Richard L. Woolworth are each independent trustees and collectively constitute
the entire Audit Committee.

Item 6. Schedule of Investments

The registrant's "Schedule I - Investments in securities of unaffiliated
issuers" (as set forth in 17 CFR 210.12-12) is included in Item 1 of this Form
N-CSR.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End
Management Investment Companies.

The Fund has delegated to Columbia Management Advisors, LLC (the "Advisor") the
responsibility to vote proxies relating to portfolio securities held by the
Fund. In deciding to delegate this responsibility to the Advisor, the Board of
Trustees of the Trust reviewed and approved the policies and procedures adopted
by the Advisor. These included the procedures that the Advisor follows when a
vote presents a conflict between the interests of the Fund and its shareholders
and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner
considered by the Advisor to be in the best interest of the Fund and its
shareholders without regard to any benefit to the Advisor, its affiliates, its
other clients or other persons. The Advisor examines each proposal and votes
against the proposal, if, in its judgment, approval or adoption of the proposal
would be expected to impact adversely the current or potential market value of
the issuer's securities. The Advisor also examines each proposal and votes the
proxies against the proposal, if, in its judgment, the proposal would be
expected to affect adversely the best interest of the Fund. The Advisor
determines the best interest of the Fund in light of the potential economic
return on the Fund's investment.



The Advisor addresses potential material conflicts of interest by having
predetermined voting guidelines. For those proposals that require special
consideration or in instances where special circumstances may require varying
from the predetermined guideline, the Advisor's Proxy Committee determines the
vote in the best interest of the Fund, without consideration of any benefit to
the Advisor, its affiliates, its other clients or other persons. The Advisor's
Proxy Committee is composed of representatives of the Advisor's equity
investments, equity research, compliance, legal and fund administration
functions. In addition to the responsibilities described above, the Proxy
Committee has the responsibility to review, on a semi-annual basis, the
Advisor's proxy voting policies to ensure consistency with internal and
regulatory agency policies and to develop additional predetermined voting
guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines
that voting on the proposal according to the predetermined guideline would be
expected to impact adversely the current or potential market value of the
issuer's securities or to affect adversely the best interest of the client.
References to the best interest of a client refer to the interest of the client
in terms of the potential economic return on the client's investment. In
determining the vote on any proposal, the Proxy Committee does not consider any
benefit other than benefits to the owner of the securities to be voted. A
member of the Proxy Committee is prohibited from voting on any proposal for
which he or she has a conflict of interest by reason of a direct relationship
with the issuer or other party affected by a given proposal. Persons making
recommendations to the Proxy Committee or its members are required to disclose
to the Committee any relationship with a party making a proposal or other
matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third
party vendor, to implement its proxy voting process. ISS provides proxy
analysis, record keeping services and vote disclosure services.
