COLONIAL CALIFORNIA INSURED MUNICIPAL FUND [photo of bridge] ANNUAL REPORT NOVEMBER 30, 2004 NOT FDIC INSURED MAY LOSE VALUE NO BANK GUARANTEE PRESIDENT'S MESSAGE Dear Shareholder: In 2004, Colonial Funds became part of the Bank of America family, one of the largest, most respected financial institutions in the United States. As a direct result of this merger, a number of changes are in the works that we believe offer significant potential benefits for our shareholders. First, some funds may be merged in order to eliminate redundancies, others may be liquidated and fund management teams will be aligned to maximize performance potential. You will receive more detailed information about these changes if your fund is affected and you may be asked to vote on certain fund changes. In this matter, your timely response will enable us to implement the changes in 2005. As a result of these changes, we believe we will offer shareholders an even stronger lineup of investment options. What will not change as we enter this next phase of consolidation is our commitment to the highest standards of performance and our dedication to superior service. Change for the good has another name: it's called improvement. It helps move us forward, and we believe that it represents progress for all our shareholders in their quest for long-term financial success. In the pages that follow, you'll find a detailed report from the fund's manager or managers on key factors that influenced your fund's performance. We hope that you will read the manager reports carefully and discuss any questions you might have with your financial advisor. As always, we thank you for choosing Colonial Funds. We appreciate your continued confidence. And, we look forward to helping you keep your long-term financial goals on target in the years to come. Sincerely, /s/ Christopher L. Wilson Christopher L.

Portfolio Manager's Report Price per share as of 11/30/04 ($) Net asset value 14.97 ------------------------------ Market price 13.61 ------------------------------ 1-year total return as of 11/30/04 (%) Net asset value 4.68 ------------------------------ Market price (6.99) Lipper California Insured Municipal Debt Funds Category average 4.49 ------------------------------ All results shown assume reinvestment of distributions. Distributions declared per common share 12/01/03-11/30/04 ($) 0.92 ------------------------------ A portion of the fund's income may be subject to the alternative minimum tax. The fund may at times purchase tax-exempt securities at a discount from their original issue price. Some or all of this discount may be included in the fund's ordinary income, and any market discount is taxable when distributed.

Ratings shown in the quality breakdown represent the lowest 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. Because the fund is actively managed, there is no guarantee that the fund will continue to invest in these sectors or maintain this quality breakdown in the future. For the 12-month period ended November 30, 2004, Colonial California Insured Municipal Fund had a negative return of 6.99%, 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 4.68% based on investment at net asset value. That was in line with the 4.49% average return of the fund's peer group, the Lipper California Insured Municipal Debt Funds Category.1 During the period, we employed a strategy to improve the overall total return characteristics of the fund. We reduced our exposure to the short maturity range (2-7 years) by selling premium coupon longer-maturity bonds which were priced to their near-term call date. We used the proceeds to invest in non-callable bonds and bonds with good call protection, maturing in approximately 20 years. We believed this maturity range offered good potential for positive total returns, a belief that was borne out as interest rates on intermediate bonds declined (and prices rose) during the period. Strategic positioning and leveraged positions helped performance The fund's performance was helped by our focus on intermediate bonds maturing in 10-20 years, which performed well during the period. The fund was also helped by our decision to reduce exposure to bonds that are priced to a short-term call date (2-7 years). Yields in this range generally rose, and prices declined, as the Federal Reserve Board (the Fed) began to move the federal funds rate higher. The fund's lower quality bonds (rated Baa or lower by Moody's) helped performance. The category generally outperformed as demand for high yield was strong in a relatively low rate environment. Lower quality bonds also provided the fund with higher income, which further contributed to the fund's total return. In addition, we sold the fund's airline bonds during the period. In the face of court rulings, we decided to reduce the fund's exposure to the sector and believed the sale price reflected good value. Leveraged positions provided the fund with additional income during the period. We have, in effect, "borrowed against" the fund's investment positions by issuing preferred shares, which pay out a short-term variable rate. When these preferred shares were issued in 1999, we invested the proceeds in bonds with longer maturities. During this reporting period, the payout rate of preferred shares was lower than the yield the fund earned from those longer-maturity bonds. However, as short-term rates rose, the fund's dividend to common shareholders was reduced. In addition, the use of leverage increases the likelihood of share price volatility and market risk. -------------- 1 Lipper Inc., a widely respected data provider in the industry, calculates an average return based on net asset value for mutual funds with similar investment objectives as the fund. 1 Portfolio Manager's Report (continued) California's outlook continues to improve As California's economy recovered and its budgetary situation improved, the state's credit rating was raised to "A" by the three major rating agencies: Standard & Poor's, Moody's and Fitch. However, we believe continued financial improvement depends on the state's ability to reduce its dependence on one-time revenue items, cut spending and restore dependability to the budget process. We will continue focusing on bonds with dedicated revenue streams that offer good value but tend to be less affected by the state's fiscal problems. For example, we expect essential services bonds, such as those issued by water and sewer authorities, to continue to make up an important part of the portfolio. /s/ Kimberly Campbell Kimberly Campbell has been the portfolio manager of Colonial California Insured Municipal Fund since October 2003. During the period March 2004 to April 2004, Ms. Campbell was on a leave of absence. Ms. Campbell has been with Columbia Management Advisors, Inc. or its predecessors or affiliate organizations since 1995. Performance data quoted represents past performance and current performance may be lower or higher. Past performance is no guarantee of future results. The values of fixed-income securities generally move inversely with changes in interest rates such that when interest rates rise, bond values fall and vice versa. 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 fund. 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.

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. Investment Goal The Fund seeks to provide current income generally exempt from ordinary federal income tax and California State personal income tax. Fund Shares The Fund may issue an unlimited number of common shares. On December 10, 1999, the Fund issued 978 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. 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 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. 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, Inc. 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. Restricted Securities Restricted securities are securities that may only be resold upon registration under federal securities laws or in transactions exempt from registration. In some cases, the issuer of restricted securities has agreed to register such securities for resale at the issuer's expense either 9 Notes to Financial Statements (continued) November 30, 2004 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 resale. 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. 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 tax-exempt or taxable 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, 2004, was 0.95%. For the year ended November 30, 2004, the Fund declared dividends to Auction Preferred shareholders amounting to $243,499, representing an average dividend rate of 1.00% 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, 2004, permanent book and tax basis differences resulting primarily from differing treatments for discount accretion/premium amortization on debt securities and market discount reclassifications were identified and reclassified among the components of the Fund's net assets as follows: UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN INCOME LOSS CAPITAL ------------- ------------- ------------- $(14,341) $14,343 $(2) Net investment income and net realized gains (losses), 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, 2004 and November 30, 2003 was as follows: NOVEMBER 30, NOVEMBER 30, 2004 2003 ----------- ----------- Distributions paid from: Tax-Exempt Income $2,806,938 $3,060,388 Ordinary Income 166 -- Long-Term Capital Gains -- -- As of November 30, 2004, 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* ---------- ---------- ----------- ------------ $207,738 $-- $-- $5,696,843 * 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, 2004, based on cost of investments for federal income tax purposes was: Unrealized appreciation $5,721,353 Unrealized depreciation (24,510) ---------- Net unrealized appreciation $5,696,843 ========== The following capital loss carryforwards may be 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 2011 889,444 2012 70,908 ---------- $1,726,238 ---------- 10 Notes to Financial Statements (continued) November 30, 2004 Under current tax rules, certain capital losses realized after October 31 may be deferred and treated as occurring on the first day of the following fiscal year. As of November 30, 2004, post-October capital losses of $73,072 attributed to security transactions were deferred to December 1, 2004. Note 4. Fees and Compensation Paid to Affiliates Columbia Management Advisors, Inc. ("Columbia") is the investment advisor to the Fund. Prior to April 1, 2004, Columbia was an indirect, wholly owned subsidiary of FleetBoston Financial Corporation ("FleetBoston"). Effective April 1, 2004, FleetBoston, including the Fund's investment advisor, was acquired by Bank of America Corporation ("BOA"). The acquisition did not change the way the Fund is managed, the investment personnel assigned to manage the Fund or the fees paid by the Fund. Investment Advisory Fee Columbia provides administrative and other services to the Fund in addition to investment advisory services. 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 contractually agreed to waive a portion of its investment advisory fee through November 30, 2004, so that such fees did not exceed an annual rate equal to 0.35%. Effective December 1, 2004, Columbia has contractually agreed to waive a portion of its investment advisory fee through November 30, 2005, so that such fees will not exceed an annual rate equal to 0.40% of the Fund's average weekly net assets, including assets applicable to the APS. 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, Columbia pays the total fees received 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 APS, exceed $50 million, an additional monthly fee. The additional fee rate is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement. This rate is applied to the average weekly net assets, including assets applicable to APS, of the Fund for that month. The Fund also pays additional fees for pricing services based on the number of securities held by the Fund. For the year ended November 30, 2004, the Fund's effective pricing and bookkeeping fee rate, inclusive of out-of-pocket expenses, was 0.081% of the Fund's average weekly net assets, including assets applicable to the APS. 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) would 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 With the exception of one officer, all officers of the Fund are employees of Columbia or its affiliates and receive no compensation from the Fund. Effective August 23, 2004, the Board of Trustees appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund, along with other affiliated funds, will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. The Fund's fee 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, 2004, the Fund paid $1,351 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, 2004, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $10,272,074 and $10,214,601, respectively. Note 6. 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 11 Notes to Financial Statements (continued) November 30, 2004 $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 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, 2004, 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 Investors Service, Inc. At November 30, 2004, investments supported by private insurers that represent greater than 5% of the total investments of the Fund were as follows: % OF TOTAL INSURER INVESTMENTS -------------------------------------------------------- MBIA Insurance Corp. 39.1 Financial Guaranty Insurance Co. 19.8 Ambac Assurance Corp. 15.2 Financial Security Assurance, Inc. 13.5 Geographic Concentration The Fund has greater than 5% of its total investments at November 30, 2004 invested in debt obligations issued by the State of California and its respective political subdivisions, agencies and public authorities. The Fund is more susceptible to economic and political factors adversely affecting issuers of the 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 and industry events 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 there is no established secondary market. Legal Proceedings Columbia, Columbia Funds Distributor, Inc. ("CFDI"), and certain of their affiliates (collectively, "the Columbia Group") have received information requests and subpoenas from various regulatory and law enforcement authorities in connection with their investigations of late trading and market timing in mutual funds as well as other industry wide issues. The Columbia Group has not uncovered any instances where Columbia or CFDI were knowingly involved in late trading of mutual fund shares. On February 24, 2004, the Securities and Exchange Commission ("SEC") filed a civil complaint in the United States District Court for the District of Massachusetts against Columbia and CFDI, alleging that they had violated certain provisions of the federal securities laws in connection with trading activity in mutual fund shares. Also on February 24, 2004, the New York Attorney General ("NYAG") filed a civil complaint in New York Supreme Court, County of New York against Columbia and CFDI alleging that Columbia and CFDI had violated certain New York anti-fraud statutes. If either Columbia or CFDI is unsuccessful in its defense of these proceedings, it could be barred from serving as an investment advisor or distributor for any investment company registered under the Investment Company Act of 1940, as amended (a "registered investment company"). Such results could prevent Columbia, CFDI or any company that is an affiliated person of Columbia and CFDI from serving as an investment advisor or distributor for any registered investment company, including your fund. Your fund has been informed by Columbia and CFDI that, if these results occur, they will seek exemptive relief from the SEC to permit them to continue to serve as your fund's investment advisor and distributor. There is no assurance that such exemptive relief will be granted. On March 15, 2004, Columbia and CFDI entered into agreements in principle with the SEC Division of Enforcement and NYAG in settlement of the charges. Under the agreements, Columbia and CFDI agreed, among other things, to the following conditions: payment of $70 million in disgorgement; 12 Notes to Financial Statements (continued) November 30, 2004 payment of $70 million in civil penalties; an order requiring Columbia and CFDI to cease and desist from violations of the antifraud provisions and other provisions of the federal securities laws; governance changes designed to maintain the independence of the mutual fund boards of trustees and ensure compliance with securities laws and their fiduciary duties; and retention of an independent consultant to review Columbia's and CFDI's compliance policies and procedures. The agreement requires the final approval of the SEC. In a separate agreement with the NYAG, the Columbia Group and its affiliate Banc of America Capital Management, LLC have agreed to collectively reduce mutual fund fees by $160 million over a five-year period. In connection with the events described in detail above, various parties have filed suit against certain funds, their Boards and/or FleetBoston (and affiliated entities). More than 300 cases (including those filed against entities unaffiliated with the funds, their Boards and/or FleetBoston and its affiliated entities) have been consolidated in a multi-district proceeding and transferred to the Federal District Court in Maryland. Recently, certain Columbia funds and affiliated entities have been named as defendants in several derivative actions under various sections of the Investment Company Act of 1940, as amended, alleging, among other things, that the fees and expenses paid by those funds are excessive. The funds and the other defendants to these actions, including Columbia and various of its affiliates, certain other mutual funds advised by Columbia and its affiliates, and various directors of such funds, have denied these allegations and are contesting the plaintiffs' claims. These suits and certain regulatory investigations are ongoing, however, based on currently available information, Columbia believes that these lawsuits are without merit, that the likelihood they will have a material adverse impact on any fund is remote, and that the lawsuits are not likely to materially affect its ability to provide investment management services to its clients, including the funds. 13 Financial Highlights Selected data for a share outstanding throughout each period is as follows (common shares unless otherwise noted): Period Year Ended November 30, Ended ------------------------------------------------------------- November 30, 2004 2003 2002 2001 2000 1999 (a) -------------------------------------------------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $ 15.21 $ 15.30 $ 15.78 $ 15.16 $ 14.29 $ 14.33 ----------- ----------- ----------- ----------- ----------- ----------- Income from Investment Operations: Net investment income 1.03(b) 1.10(b) 1.17(b)(c) 1.19(b) 1.18(d) 0.05 Net realized and unrealized gain (loss) on investments, futures contracts and written options (0.26) (0.09) (0.46)(c) 0.59 1.07 (0.06) ----------- ----------- ----------- ----------- ----------- ----------- Total from Investment Operations 0.77 1.01 0.71 1.78 2.25 (0.01) Less Distributions Declared to Preferred Shareholders: From net investment income (0.09) 0.08) (0.12) (0.24) (0.34) -- ----------- ----------- ----------- ----------- ----------- ----------- Total from Investment Operations Applicable to Common Shareholders 0.68 0.93 0.59 1.54 1.91 (0.01) Less Distributions Declared to Common Shareholders: From net investment income (0.92) (1.02) (1.07) (0.92) (0.90) -- ----------- ----------- ----------- ----------- ----------- ----------- Less Share Transactions: Offering costs -- common shares -- -- -- -- --(e) (0.03) Commission and offering costs -- preferred shares -- -- -- -- (0.14) -- ----------- ----------- ----------- ----------- ----------- ----------- Total Share Transactions -- -- -- -- (0.14) (0.03) ----------- ----------- ----------- ----------- ----------- ----------- Net Asset Value, End of Period $ 14.97 $ 15.21 $ 15.30 $ 15.78 $ 15.16 $ 14.29 ----------- ----------- ----------- ----------- ----------- ----------- Market price per share -- common shares $ 13.61 $ 15.60 $ 16.40 $ 16.60 $ 12.69 $ 15.00 ----------- ----------- ----------- ----------- ----------- ----------- Total return -- based on market value -- common shares (f)(g) (6.99)% 1.65% 5.67% 38.91% (9.86)% 0.00%(h) Ratios to Average Net Assets/Supplemental Data: Expenses (i)(j) 0.87%(k) 0.88%(k) 0.86%(k) 0.86%(k) 0.87%(k) 0.55%(l) Net investment income before preferred stock dividends (i)(j) 6.89% 7.17% 7.57%(c) 7.58% 8.27% 4.12%(l) Net investment income after preferred stock dividends (i)(j) 6.30% 6.63% 6.81%(c) 6.02% 5.93% 4.12%(l) Voluntary waiver/reimbursement (j) 0.21% 0.26% 0.23% 0.22% 0.27% 1.08%(l) Portfolio turnover rate 16% 10% 11% 7% 22% 0%(h) Net assets, end of period (000's) -- common shares $ 41,631 $ 42,260 $ 42,432 $ 43,678 $ 41,947 $ 34,382 (a) The Fund commenced investment operations on October 29, 1999.

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), which 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, 2004 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP Boston, Massachusetts January 19, 2005 16 Unaudited Information Federal Income Tax Information 99.99% of the distributions from net investment income will be treated as exempt income for federal income tax purposes. -------------------------------------------------------------------------------- As of December 31, 2004, 9.07% of distributions from net investment income is subject to the alternative minimum tax. 17 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 (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 EquiServe Trust Company, N.A. by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone at 1-800-730-6001. 18 Trustees and Officers The Trustees/Directors serve terms of indefinite duration.

(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: o 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; o The request should be addressed to the Audit Committee with copies to the Fund Treasurer and/or Director of Trustee Administration; o 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. o 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: o A general description of the services, and o Actual billed and projected fees, and o 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, 2004 and November 30, 2003 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, 2004 and November 30, 2003 are disclosed in (b) through (d) of this Item. During the fiscal years ended November 30, 2004 and November 30, 2003, 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, 2004 and November 30, 2003 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, Inc. (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 policies and regulatory agency policies and to develop additional voting guidelines to assist in the review of proxy proposals. The Proxy Committee may vary from the 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.
