COLONIAL CALIFORNIA INSURED MUNICIPAL FUND [photo of bridge] SEMIANNUAL REPORT MAY 31, 2003 PRESIDENT'S MESSAGE DEAR SHAREHOLDER: The US bond market continued to reward investors with solid returns for the period covered by this report. As key economic indicators sent mixed signals, the US economy continued to struggle and interest rates declined. The Federal Reserve Board lowered a key short-term interest rate--the federal funds rate--in November, to 1.25%--a new record low.1 The yield on the 10-year US Treasury bond fell to a 45-year low of 3.3% near the end of the period. Although the environment was favorable to bonds, declining interest rates and relatively low inflation raised the fear of deflation for the first time since the 1930s. Bonds reported gains across all sectors. Leadership rotated from higher quality bonds, which were the top performers in the previous period, to lower quality bonds. However, in the municipal sector, higher quality bonds generally outperformed high-yield issues. The following report will provide you with more detailed information about the fund's performance and the investment strategies used by portfolio manager Paul Aston. For more information, please contact your financial advisor. CONSOLIDATION AND A NEW NAME: COLUMBIA On April 1, 2003, six of the asset management firms brought together when Columbia Management Group, Inc. was formed were consolidated and renamed Columbia Management Advisors, Inc. (Columbia Management). This consolidation does not affect the management or investment objectives of your fund and is the next step in our efforts to create a consistent identity and to streamline our organization. Although the name of the asset manager familiar to you has changed, what hasn't changed is the commitment of our specialized investment teams to a multi-disciplined approach to investing, focused on our goal of offering shareholders the best products and services. As always, we thank you for choosing Colonial California Insured Municipal Fund and for giving us the opportunity to help you build a strong financial future. /s/ Joseph R. Palombo Joseph R. Palombo President -------------------------------------------------------------------------------- MEET THE NEW PRESIDENT Joseph R. Palombo, president and chairman of the Board of Trustees for Liberty Funds, is also chief operating officer and executive vice president of Columbia Management. Mr. Palombo has over 19 years of experience in the financial services industry. Prior to joining Columbia Management, he was chief operating officer and chief compliance officer for Putnam Mutual Funds. Prior to that, he was a partner at Coopers & Lybrand. Mr. Palombo received his degree in economics/accounting from the College of the Holy Cross, where he was a member of Phi Beta Kappa. He earned his master's degree in taxation from Bentley College and participated in the Executive Program at the Amos B. Tuck School at Dartmouth College. -------------------------------------------------------------------------------- NOT FDIC INSURED MAY LOSE VALUE NO BANK GUARANTEE 1 On June 25, 2003, the Federal Reserve Board cut the federal funds rate to 1.00%. Economic and market conditions change frequently. There is no assurance that the trends described in this report will continue or commence. PORTFOLIO MANAGER'S REPORT For the six-month period ended May 31, 2003, Colonial California Insured Municipal Fund returned 9.60%, based on net asset value. The fund's peer group, the Lipper California Insured Municipal Debt Funds Category, averaged a 9.20% return.1 The fund benefited as economic concerns pushed interest rates lower and bond prices higher. Although California issued a record amount of new debt to meet budget shortfalls, the state's size and high marginal tax rate ensured strong demand especially for higher-quality insured issues. The fund gained an edge from investing in higher-yielding securities and in longer-maturity zero coupon bonds, which appreciated nicely as interest rates declined. The prerefunding of several bond holdings also helped performance. Prerefunding occurs when an issuer sells new bonds and invests the proceeds in US Treasury securities that are pledged to pay off the older debt. This improves the bond's quality and boosts the value of the older bonds. The fund also benefited from being leveraged through its preferred shares, which paid out a variable rate that was well below what the fund was able to earn on its investments in higher yielding securities. However, airline bonds slightly hampered performance during the period as did short positions in US Treasury futures contracts, which are employed to reduce the overall duration of the fund. Additions to the portfolio during the period included tobacco bonds, which are backed by settlement money from tobacco companies. They became attractive buys after their yields rose following a negative court ruling in Illinois. In addition, we also bought and sold options on US Treasury futures contracts in order to hedge the fund's exposure to interest rate volatility. We sold hospital bonds, which we believe has become a less attractive sector in California, and remain focused on revenue bonds, especially education, utilities and water and sewer issues. Additionally, we experienced some single family housing bonds being called away as a result of increased mortgage prepayment activity. Overall, our expectation is that California should respond well to improving economic conditions. We think new issuance will remain high and demand strong. Recent credit downgrades, however, may boost the state's financing costs for new issuance. Our strategy will remain focused on income as we look for opportunities to add high-quality securities at advantageous prices. /s/ Paul A. Aston Paul A. Aston is the head of Columbia Management Group's tax-exempt fixed income quantitative strategy department and portfolio manager of Colonial California Insured Municipal Fund. Mr. Aston joined Columbia Management in 2002. Prior to January 1, 2003, Maureen G. Newman was the fund's manager. Past performance is no guarantee of future investment results. The principal value and investment returns will fluctuate, resulting in a gain or loss on sale. Tax-exempt investing offers current tax-free income, but it also involves certain risks. The value of the fund shares will be affected by interest rate changes and the creditworthiness of issues held in the funds. Investing in high yield securities offers the potential for high current income and attractive total return, but involves certain risks. Lower-rated bond risks include default of the issuer and rising interest rates. Single-state municipal bond funds pose additional risks due to limited geographical diversification. Interest income from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. 1 Lipper Inc., a widely respected data provider in the industry, calculates an average total return for mutual funds with similar investment objectives as those of the fund.

ACCOUNTING POLICIES ORGANIZATION: Colonial California 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. The Fund's investment goal is to provide current income generally exempt from ordinary federal income tax and California state personal income tax. The Fund is authorized to issue an unlimited number of common shares of beneficial interest and 978 Auction Preferred Shares ("APS"). 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 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 AND TRANSACTIONS: Debt securities generally are valued by a pricing service based upon market transactions for normal, institutional-size trading units of similar securities. When management deems it appropriate, an over-the-counter or exchange bid quotation is used. Options are valued at the last reported sale price, or in the absence of a sale, the mean between the last quoted bid and asking price. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded. Short-term obligations with a maturity of 60 days or less are valued at amortized cost. Investments for which market quotations are not readily available, or quotations which management believes are not appropriate, are valued at fair value under procedures approved by the Board of Trustees. Security transactions are accounted for on the date the securities are purchased, sold or mature. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes. The Fund may trade securities on other than normal settlement terms. This may increase the risk if the other party to the transaction fails to deliver and causes the Fund to subsequently invest at less advantageous prices. FEDERAL INCOME TAXES: Consistent with the Fund's policy to qualify as a regulated investment company and to distribute all of its taxable and tax-exempt income, no federal income tax has been accrued. INTEREST INCOME, DEBT DISCOUNT AND PREMIUM: Interest income is recorded on the accrual basis. Premium and discount are being amortized and accreted, respectively, for all debt securities. DISTRIBUTIONS TO SHAREHOLDERS: Distributions to common shareholders are recorded on the ex-date. Distributions to preferred shareholders are recorded daily and are 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 May 31, 2003 was 1.15%. For the six months ended May 31, 2003, the Fund declared dividends to Auction Preferred shareholders amounting to $120,379 representing an average APS dividend rate of 0.99%. NOTE 2. FEDERAL TAX INFORMATION Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. The following capital loss carryforwards, determined as of November 30, 2002, are available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: YEAR OF CAPITAL LOSS EXPIRATION CARRYFORWARD ---------- ------------ 2008 $ 5,151 2010 760,735 -------- $765,886 -------- NOTE 3. FEES AND COMPENSATION PAID TO AFFILIATES MANAGEMENT FEE: On April 1, 2003, Colonial Management Associates, Inc. ("Colonial"), the investment advisor to the Fund merged into the Columbia Management Advisors, Inc., ("Columbia"), formerly known as Columbia Management Co., an indirect, wholly-owned subsidiary of FleetBoston Financial Corporation. At the time of the merger, Columbia assumed the obligations of Colonial with respect to the Fund. The merger did not change the way the Fund is managed, the investment personnel assigned to manage the Fund or the fees paid by the Fund. 8 NOTES TO FINANCIAL STATEMENTS (CONTINUED) May 31, 2003 (Unaudited) Columbia is the investment advisor of the Fund and furnishes accounting and other services and office facilities for a fee to be paid monthly at the annual rate of 0.65% of the Fund's average weekly net assets, including assets applicable to the APS. Through November 30, 2004, Columbia has contractually agreed to waive a portion of the fee so that it will not exceed 0.35% annually. 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 Bank and Trust Company ("State Street"). Columbia pays fees to State Street under the Outsourcing Agreement. Under its pricing and bookkeeping agreement with the Fund, Columbia receives from the Fund an annual flat fee of $10,000, paid monthly, and in any month that the Fund's average weekly net assets, including assets applicable to the APS, are more than $50 million, a monthly fee equal to the average weekly net assets, including assets applicable to the APS, of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement. For the six months ended May 31, 2003, the annualized net asset based fee rate was 0.033%. The Fund also pays out-of-pocket costs for pricing services. EXPENSE LIMITS: Columbia has voluntarily agreed to waive fees and bear certain Fund expenses to the extent that total expenses (exclusive of management fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) exceed 0.20% annually of the Fund's average weekly net assets, including assets applicable to the APS. This arrangement may be modified or terminated by Columbia at any time. OTHER: The Fund pays no compensation to its officers, all of whom are employees of Columbia or its affiliates. The Fund's Independent 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. The Fund has an agreement with its custodian bank under which $1,933 of custody fees were reduced by balance credits for the six months ended May 31, 2003. 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. NOTE 4. PREFERRED SHARES The Fund currently has outstanding 978 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 of the APS. At May 31, 2003, there were no such restrictions on the Fund. NOTE 5. PORTFOLIO INFORMATION INVESTMENT ACTIVITY: During the six months ended May 31, 2003, purchases and sales of investments, other than short-term obligations, were $728,445 and $1,825,167, respectively. Unrealized appreciation (depreciation) at May 31, 2003, based on cost of investments for federal income tax purposes, was: Gross unrealized appreciation $9,617,176 Gross unrealized depreciation (380,757) ---------- Net unrealized appreciation $9,236,419 ========== FUTURES CONTRACTS AND OPTIONS: 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 different 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 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. 9 NOTES TO FINANCIAL STATEMENTS (CONTINUED) May 31, 2003 (Unaudited) Upon entering into a futures contract, the Fund deposits cash or securities with its custodian 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 payable or receivable and offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. The Fund may write call and put options on futures it owns or in which it may invest. Writing put options tends to increase the Fund's exposure to the underlying instrument. Writing call options tends to decrease the Fund's exposure to the underlying instrument. When the Fund writes a call or put option, an amount equal to the premium received is recorded as a liability and subsequently marked-to-market to reflect the current value of the option written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against the amounts paid on the underlying future transaction to determine the realized gain or loss. The Fund as a writer of an option has no control over whether the underlying future may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the future underlying the written option. There is the risk the Fund may not be able to enter into a closing transaction because of an illiquid market. The Fund may also purchase put and call options. Purchasing call options tends to increase the Fund's exposure to the underlying instrument. Purchasing put options tends to decrease the Fund's exposure to the underlying instrument. The Fund pays a premium which is included in the Fund's Statement of Assets and Liabilities as an investment and subsequently marked-to-market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying future transaction to determine the realized gain or loss. For the six months ended May 31, 2003, transactions in written options were as follows: NUMBER OF PREMIUMS CONTRACTS RECEIVED --------- -------- Options Outstanding at November 30, 2002 -- $ -- Options Written - Call 123 104,386 Options Written - Put 123 62,745 Options Closed -- -- Options Expired -- -- Options Exercised -- -- ------- -------- Options Outstanding at May 31, 2003 246 $167,131 ------- -------- Refer to the Fund's Investment Portfolio for a summary of open futures contracts and written options at May 31, 2003. OTHER: There are certain risks arising from geographic concentration in any state. Certain revenue or tax related events in a state may impair the ability of certain issuers of municipal securities to pay principal and interest on their obligations. The Fund may focus its investments in certain industries, subjecting it to greater risk than a fund that is more diversified. Restricted securities are securities that may only be resold upon registration under federal securities laws or in transactions exempt from such registration. In some cases, the issuer of restricted securities has agreed to register such securities for resale, at the issuer's expense either upon demand by the Fund or in connection with another registered offering of the securities. Many restricted securities may be resold in the secondary market in transactions exempt from registration. Such restricted securities may be determined to be liquid under criteria established by the Board of Trustees. The Fund will not incur any registration costs upon such resales. The Fund's restricted securities are valued at the price provided by dealers in the secondary market or, if no market prices are available, at the fair value as determined in good faith using methods approved by the Board of Trustees. 10 FINANCIAL HIGHLIGHTS Selected data for a share outstanding throughout each period is as follows (common shares unless otherwise noted):

(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 provisions 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 7.51% to 7.57% and increase the ratio of net investment income (adjusted for dividend payments to preferred shareholders) from 6.75% to 6.81%. 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 reclassifications of differences between book and tax basis net investment income. (e) Represents less than $0.01 per share. (f) Total return at market value assuming all distributions reinvested at prices calculated in accordance with the Dividend Reinvestment Plan. (g) Had the Advisor not waived or reimbursed a portion of expenses, total return would have been reduced. (h) Not annualized. (i) The benefits derived from custody credits and directed brokerage arrangements, if applicable, had an impact of less than 0.01%. (j) Ratios reflect average net assets available to common shares only. (k) Annualized. (l) Ratios calculated using average net assets of the Fund equals 0.55%.

Nelson 967 11 Thomas E. Stitzel 967 11 12 DIVIDEND REINVESTMENT PLAN COLONIAL CALIFORNIA 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 EquiServe Trust Company, N.A. (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 New York 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 EquiServe Trust Company, N.A., by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone at 1-800-730-6001. 13 This page intentionally left blank. This page intentionally left blank. This page intentionally left blank.
