The Russell 2000 Value Index measures the performance of those Russell 2000 Index companies with lower price-to-book ratios and lower forecasted growth values. Unlike the fund, indices are not investments, they do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower. All results shown assume reinvestment of distributions. Class Z shares are sold at net asset value with no Rule 12b-1 fees. Class Z shares have limited eligibility and the investment minimum requirement may vary. Please see the fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. Performance results reflect any voluntary waivers or reimbursement of fund expenses by the advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. 1 Understanding Your Expenses - Columbia Small Cap Value Fund I Shareholder expense example As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare this cost with the continuing costs of investing in other mutual funds. Analyzing your fund's expenses by share class To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in each share class during the period. The information in the following table is based on an initial investment of $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated using the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Estimating your actual expenses To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period: .. For shareholders who receive their account statements from Columbia Management Services, Inc., your account balance is available online at www.columbiafunds.com or by calling Shareholder Services at 800.345.6611. .. For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance. 1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your share class. You will find this number in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. 01/01/06 - 06/30/06 Account value Account value Fund's at the at the Expenses paid annualized beginning of the end of the during the expense period ($) period ($) period ($) ratio (%) Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,091.10 1,018.35 6.74 6.51 1.30 Class B 1,000.00 1,000.00 1,086.98 1,014.63 10.61 10.24 2.05 Class C 1,000.00 1,000.00 1,087.03 1,014.63 10.61 10.24 2.05 Class Z 1,000.00 1,000.00 1,092.38 1,019.59 5.45 5.26 1.05 Expenses paid during the period are equal to the annualized expense ratio for the share class, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the transfer agent not waived a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only continuing costs of investing in the fund and do not reflect any transaction costs, such as sales charges or redemption or exchange fees. Therefore, the hypothetical examples provided will not help you determine the relative total costs of owning different funds. If these transaction costs were included, your costs would have been higher. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transaction costs, such as sales charges or redemption or exchange fees. 2 Economic Update - Columbia Small Cap Value Fund I Summary For the 12-month period ended June 30, 2006 .. Despite volatility, the broad stock market, as measured by the S&P 500 Index, returned 8.63%. Small-cap stocks did better than large- and mid-cap stocks, as measured by the Russell 2000 Index. [GRAPHIC] +8.63% S&P Index [GRAPHIC] +14.58% Russell Index .. Investment-grade bonds delivered negative returns, as measured by the Lehman Brothers Aggregate Bond Index. High-yield bonds led the fixed-income markets, as measured by the Merrill Lynch US High Yield, Cash Pay Only Index. [GRAPHIC] -0.81% Lehman Index [GRAPHIC] +4.65% Merrill Lynch Index The US economy grew at a solid but uneven pace during the 12-month period that began July 1, 2005 and ended June 30, 2006. Gross domestic product (GDP) expanded at an estimated annualized rate of approximately 3.5% as job growth provided support for consumer spending. Rising profits freed up cash for business spending, which picked up during the period. Personal income rose. Yet, these overall measures masked a host of challenges, which led to considerable volatility during the 12-month period. Late last summer, hurricanes Katrina and Rita devastated the Gulf Coast, disrupting the flow of energy products and leaving millions of Americans without homes or jobs. Consumer confidence plummeted in the wake of the storms. The impact on the labor market was actually less than anticipated. However, economic growth fell to a mere 1.7% in the fourth quarter. The economy regained considerable momentum early in 2006. GDP growth rebounded to 5.6%. Job growth resumed at a healthy pace, and consumer confidence rebounded. Yet, the once strong housing market has shown signs of slowing. Inflation edged higher as record-high energy prices took a bigger bite out of household budgets. Consumer spending growth edged lower in the final months of the period, and economic growth declined to 2.5% for the last quarter of the reporting period. Eight short-term rate hikes -- and more to come? The Federal Reserve Board (the Fed) raised the federal funds rate, a key short-term rate, from 3.25% to 5.25% in eight consecutive one-quarter point increases. In the wake of hurricanes Katrina and Rita, some market observers speculated that the Fed might curtail its rate hikes. However, outgoing Fed chairman Greenspan indicated that inflation was a greater concern than the sustainability of economic growth, and the Fed, under new chairman Ben Bernanke, continued to raise short-term interest rates through the end of the period. Stocks moved higher Despite bouts of volatility, the S&P 500 Index -- a broad measure of large company stock market performance -- returned a respectable 8.63% for this reporting period. Small- and mid-cap stocks did even better. The Russell 2000(R) Index returned 14.58% while the Russell Midcap Index returned 13.66%. Energy stocks led the US stock market as commodity prices continued to climb. Foreign stock markets generally did better than the US market. The MSCI EAFE Index, which tracks stock market performance in industrialized countries outside the United States, returned 26.56%. After a solid start, bond market sputters The US bond market headed downward during the period as interest rates moved higher across the maturity spectrum. The yield on the 10-year US Treasury note, a bellwether for the bond market, rose more than one full percentage point and ended the period at 5.14%. In this environment, the Lehman Brothers Aggregate Bond Index returned negative 0.81% for the 12-month period. High-yield bonds led the fixed income markets. The Merrill Lynch US High Yield, Cash Pay Only Index returned 4.65%. The Russell Midcap Index measures the performance of the 800 smallest companies in the Russell 1000 Index, which represent approximately 25% of the total market capitalization of the Russell 1000 Index. The MSCI EAFE is a free float-market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. The S&P 500 Index is an unmanaged index that tracks the performance of 500 widely held, large-capitalization US stocks. The Russell 2000 Index is an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest US companies based on market capitalization. The Lehman Brothers Aggregate Bond Index is a market value-weighted index that tracks the performance of fixed-rate, publicly placed, dollar-denominated, non-convertible investment grade debt issues with at least $250 par amount outstanding and with at least one year to final maturity. The Merrill Lynch US High Yield, Cash Pay Only Index tracks the daily price, pay days, and total return performance of non-investment-grade corporate bonds. Unlike mutual funds, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. 3 Portfolio Manager's Report - Columbia Small Cap Value Fund I Performance data quoted represents past performance and current performance may be lower or higher.

The fund beat the Russell 2000 Value Index, which returned 14.61%, and the Morningstar Small Value Category average, which was 12.64%. Sector allocation and stock selection were nearly equal contributors in helping the fund outpace the Russell index. Stock picking was especially strong in the financials, information technology and consumer staples sectors, while the fund's energy and information technology sector weights made a positive contribution relative to the index. Our focus remained on companies that we believe have strong competitive and financial positions, good earnings growth prospects and reasonable stock valuations. Small-cap stocks post another year of gains Small-cap stocks led the market's rise, as investors' appetite for risk remained strong and earnings growth solid. An accommodative lending environment further aided small companies. In the second quarter, mounting uncertainty over the Federal Reserve's next moves and a tightening of global liquidity led to increased market volatility. Small-cap stocks suffered in the downturn, but recovered as inflation fears subsided near the end of the period. Financials stocks delivered superior returns The fund's most impressive returns came from financial stocks, particularly specialty financials, insurers, and real estate investment trusts (REITs) that we had bought at attractive valuations. Our focus was on companies that we believed could profit from rising interest rates. In the specialty finance group, Cash America International, Inc. (0.8% of net assets), a pawn shop operator in the United States and United Kingdom, stood out. It benefited from growing demand for its services, higher interest rates and rising gold and silver prices. Insurers that realized rate increases after the Gulf Coast hurricanes also did quite well. Among them was Navigators Group, Inc. (0.8% of net assets), which specializes in insurance for marine boats and offshore energy rigs. The fund did well to have a below-average stake in REITs, which lagged other financial industries, and benefited from its focus on economically-sensitive issues, such as apartments, office parks and industrials. Energy stocks were strong Stock selection in the energy sector boosted returns. In addition, the fund had slightly more exposure to the sector than the index -- which amplified the impact of its good returns. Winners included Lufkin Industries, Inc. (0.9% of net assets), Western Gas Resources, Inc. (0.7% of net assets) and Maverick Tube Corp. (no longer in the portfolio). Lufkin, which makes parts for oil well equipment, benefited from increased investor attention. Western Gas, an exploration and production company, and Maverick, which supplies tubular goods for drillers and pipeline companies, rallied (C)2005 by Morningstar, Inc. All rights reserved.

In addition, Peabody Energy Corp. (.5% of net assets), the largest publicly held coal company in the world, had a stellar year as coal prices climbed and the company's market share grew. Consumer staples stocks further aided returns, buoyed by investments in specialty food companies that produced strong gains. Quality bias hampered health care returns Stock selection in health care detracted from performance, as the relatively inexpensive, high-quality stocks the fund owned trailed higher-risk names in the sector. We had no exposure to biotechnology or to specialty pharmaceutical stocks. In addition, many of the fund's health care service and facilities stocks posted disappointing returns. Detractors included Kindred Healthcare, Inc. (0.6% of net assets), an operator of hospital and nursing facilities, whose stock price fell amid concerns the government would freeze or reduce certain hospital payment rates. Slower economic growth ahead? Going forward, we expect economic growth to slow and interest rates to creep higher. How small-cap stocks fare will largely depend on whether investors remain comfortable with the risk associated with smaller companies as well as the lending environment for small companies. Access to the capital markets is an important element in funding growth for small companies. We believe the fund's quality bias should stand it in good stead if investors gravitate toward companies with stronger financial conditions in an environment of slower economic growth.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments. Investments in small-cap stocks may be subject to greater volatility and price fluctuations because they may be thinly traded and less liquid than investments in larger companies. Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may not approach the value the advisor has placed on it. 5 Fund Profile - Columbia Small Cap Value Fund I Performance data quoted represents past performance and current performance may be lower or higher.

Prior to March 24, 2006, the Fund was a series of Columbia Funds Trust VI. Investment Goal The Fund seeks long-term growth by investing primarily in smaller capitalization equity securities. Fund Shares The Fund may issue an unlimited number of shares and offers four classes of shares: Class A, Class B, Class C and Class Z. Each share class has its own sales charge and expense structure. Class A shares are subject to a maximum front-end sales charge of 5.75% based on the amount of initial investment. Class A shares purchased without an initial sales charge in accounts aggregating $1 million to $50 million at the time of purchase are subject to a 1.00% contingent deferred sales charge ("CDSC") if the shares are sold within twelve months of the time of the purchase. Class B shares are subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will convert to Class A shares in a certain number of years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class Z shares, as described in the Fund's prospectus. 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 Equity securities are valued at the last sale price on the principal exchange on which they trade, except for securities traded on the NASDAQ, which are valued at the NASDAQ official close price. Unlisted securities or listed securities for which there were no sales during the day are valued at the closing bid price on such exchanges or over-the-counter markets. Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value. Investments for which market quotations are not readily available, or that 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. Repurchase Agreements The Fund may engage in repurchase agreement transactions with institutions that the Fund's investment advisor has determined are creditworthy. The Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Collateral is at least equal, at all times, to the value of the repurchase obligation including interest. A repurchase agreement transaction involves certain risks in the event of default or insolvency of the counterparty. These risks include possible delays or restrictions upon the Fund's ability to dispose of the underlying securities and a possible decline in the value of the underlying securities during the period while the Fund seeks to assert its rights. 24 Columbia Small Cap Value Fund I (June 30, 2006) Income Recognition Interest income is recorded on the accrual basis. Corporate actions and dividend income are recorded on the ex-date except for certain foreign securities which are recorded as soon after ex-date as the Fund becomes aware of such, net of non-reclaimable tax withholdings. Awards from class action litigation are recorded as a reduction of cost if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains. The Fund estimates components of distributions from real estate investment trusts (REITs). Distributions received from Real Estate Investment Trusts (REITs) in excess of income are recorded as a reduction of the cost of the related investments and/or realized gain. If the Fund no longer owns the applicable securities, any distributions received in excess of income are recorded as realized gains. Foreign Currency Transactions The values of all assets and liabilities quoted in foreign currencies are translated into U.S. dollars at that day's exchange rates. Net realized and unrealized gains (losses) on foreign currency transactions include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes. For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments. Determination of Class Net Asset Values All income, expenses (other than class-specific expenses, as shown on the Statement of Operations), and realized and unrealized gains (losses), are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class. 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 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 shareholders are recorded on ex-date. Net realized capital gains, if any, are distributed at least annually. 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 June 30, 2006, permanent book and tax basis differences resulting primarily from differing treatments for net operating losses and distribution reclassifications were identified and reclassified among the components of the Fund's net assets as follows: Accumulated Undistributed Net Realized Paid-In Net Investment Loss Gain Capital $524,963 $(524,963) $-- Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. 25 Columbia Small Cap Value Fund I (June 30, 2006) The tax character of distributions paid during the years ended June 30, 2006 and June 30, 2005 was as follows: June 30, 2006 June 30, 2005 Distributions paid from: Ordinary Income* $ 3,561,544 $23,936,007 Long-Term Capital Gains 29,825,315 31,977,443 *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of June 30, 2006 the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Net Unrealized Ordinary Long-term Appreciation Income Capital Gains (Depreciation)* $4,687,568 $28,039,810 $247,589,114 *The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to the deferral of losses from wash sales. Unrealized appreciation and depreciation at June 30, 2006, based on cost of investments for federal income tax purposes, was: Unrealized appreciation $261,311,935 Unrealized depreciation (13,722,821) Net unrealized appreciation $247,589,114 The following capital loss carryforwards, determined as of June 30, 2005, 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 Expiration Capital Loss Carryforward 2007 $1,233,446 2009 2,466,892 2012 3,700,337 ---------- $7,400,675 ---------- Capital loss carryforwards of $1,233,446 were utilized during the year ended June 30, 2006. In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement 109 (the "Interpretation"). This Interpretation is effective for fiscal years beginning after December 15, 2006 and is to be applied to tax positions upon initial adoption. This Interpretation prescribes a minimum recognition threshold and measurement method for the financial statement recognition of tax positions taken or expected to be taken in a tax return and also requires certain expanded disclosures. Management has recently begun to evaluate the application of this Interpretation to the Fund and has not at this time quantified the impact, if any, resulting from the adoption of this Interpretation on the Fund's financial statements. 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 investment advisor to 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 based on the Fund's average daily net assets at the following annual rates: Average Daily Net Assets Annual Fee Rate First $500 million 0.80% $500 to $1 billion 0.75% Over $1 billion 0.70% For the year ended June 30, 2006, the Fund's effective investment advisory fee rate was 0.78% of the Fund's average daily net assets. 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 State Street the total fees collected under the pricing and bookkeeping agreement. 26 Columbia Small Cap Value Fund I (June 30, 2006) 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 daily net assets for the month; provided that during any 12-month period, the aggregate fee, exclusive of out-of-pocket expenses and charges, 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 daily 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 June 30, 2006, the effective pricing and bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was 0.020% of the Fund's average daily net assets. Transfer Agent Fee Columbia Management Services, Inc. (the "Transfer Agent"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, provides shareholder services to the Fund. On August 22, 2005, Columbia Funds Services, Inc. was renamed Columbia Management Services, Inc. The Transfer Agent has contracted with Boston Financial Data Services ("BFDS") to serve as sub-transfer agent. The Transfer Agent is entitled to receive a fee for its services, paid monthly, at the annual rate of $17.00 per open account plus sub-transfer agent fees (exclusive of BFDS fees) calculated based on assets held in omnibus accounts and intended to recover the cost of payments to third parties for services to those accounts. The Transfer Agent may also retain, as additional compensation for its services, fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcript fees due the Transfer Agent from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts the Transfer Agent maintains in connection with its services to the Fund. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. Prior to April 1, 2006, the Transfer Agent received a fee, paid monthly, at the annual rate of $15.23 per open account and prior to November 1, 2005, the annual rate was $28.00. The Transfer Agent also received reimbursement for certain out-of-pocket expenses. For the period September 1, 2005 through October 31, 2005, the Transfer Agent voluntarily waived fees of $65,185 for the Fund. For the year ended June 30, 2006, the Fund's effective transfer agent fee rate, inclusive of out-of-pocket expenses and net of fee waivers, was 0.18%. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and a wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. On August 22, 2005, Columbia Funds Distributor, Inc. was renamed Columbia Management Distributors, Inc. For the year ended June 30, 2006, the Distributor has retained net underwriting discounts of $98,620 on sales of the Fund's Class A shares and received net CDSC of $308, $183,704 and $12,635 on Class A, Class B and Class C share redemptions, respectively. The Fund has adopted a Rule 12b-1 plan (the "Plan") which requires the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets of the Fund attributable to Class A, Class B and Class C shares. The Plan also requires the payment of a monthly distribution fee to the Distributor at the annual rate of 0.75% of the average daily net assets attributable to Class B and Class C shares only. The CDSC and the distribution fees received from the Plan are used principally as repayment to the Distributor for amounts paid by the Distributor to dealers who sold such shares. 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. The Board of Trustees has 27 Columbia Small Cap Value Fund I (June 30, 2006) 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 Chief Compliance Officer position. The Fund's fee for the Office of 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 June 30, 2006, the Fund paid $2,658 to Columbia for such services. This amount is included in "Other expenses" on the Statement of Operations. Note 5. Purchases and Sales of Securities For the year ended June 30, 2006, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $248,330,023 and $255,289,629, respectively. Note 6. Line of Credit The Fund and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit provided by State Street Bank and Trust Company. Borrowings are used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. For the year ended June 30, 2006, the Fund did not borrow under this arrangement. Note 7. Shares of Beneficial Interest As of June 30, 2006, the Fund had a shareholder that held 9.8% of the shares outstanding whose shares were beneficially owned by participant accounts over which Bank of America and/or its affiliates had either sole or joint investment discretion. As of June 30, 2006, the Fund had shareholders that held greater than 5% of the shares outstanding. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. The number of such accounts and the percentage of shares of beneficial interest outstanding held therein are as follows: Number of % of Shares Shareholders Outstanding Held 2 11.96% Note 8. Other During the year ended June 30, 2006, the Fund purchased shares of a security due to a trading error. This position was subsequently sold at a loss of $9,718. The Fund has been reimbursed by Columbia. Note 9. Disclosure of Significant Risks and Contingencies Industry Focus The Fund may focus its investments in certain industries, subjecting it to greater risk than a fund that is more diversified. 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 agreed, among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease 28 Columbia Small Cap Value Fund I (June 30, 2006) 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 management fees for certain Columbia Funds (including the former Nations Funds) and other mutual funds 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 developed by an independent distribution consultant and approved by the SEC. The independent distribution consultant has been in consultation with the staff of the SEC and has submitted a proposed plan of distribution. The SEC has not yet approved a final plan of distribution. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds. 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. On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law. On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds Trusts and the Columbia Acorn Trusts. As to Columbia and the Distributor, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 ("ICA") and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed. On March 21, 2005, a purported class action was filed 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. On April 4, 2006, the plaintiffs and the Columbia defendants named in the MDL, including the Columbia Funds, entered into a term sheet containing the principal terms of a stipulation of settlement that would settle all Columbia-related claims in the MDL described above, including the CDSC Lawsuit. On April 6, 2006, the U.S. District Court for the District of Maryland stayed all actions with respect to those Columbia-related claims. The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made. 29 Columbia Small Cap Value Fund I (June 30, 2006) 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 purpose. 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 and this appeal is pending. For the year ended June 30, 2006, Columbia has assumed $9,626 of legal, consulting services and Trustees' fees incurred by the Fund in connection with these matters. 30 Report of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia Small Cap Value Fund I 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 Columbia Small Cap Value Fund I (the "Fund") (a series of Columbia Funds Series Trust I, formerly a series of Columbia Funds Trust VI) at June 30, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, 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 June 30, 2006 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP Boston, Massachusetts August 25, 2006 31 Unaudited Information - Columbia Small Cap Value Fund I Federal Income Tax Information For the fiscal year ended June 30, 2006, the Fund designates long-term capital gains of $47,477,793. 100% of the ordinary income distributed by the Fund, for the year ended June 30, 2006, qualifies for the corporate dividends received deduction. For non-corporate shareholders 100%, or the maximum amount allowable under the Jobs and Growth Tax Relief Reconciliation Act of 2003, of income earned by the Fund for the period July 1, 2005 to June 30, 2006 may represent qualified dividend income.

The Lehman Brothers Municipal Bond Index is an unmanaged index considered representative of the broad market for investment-grade, tax exempt bonds with a maturity of at least one year. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower. All results shown assume reinvestment of distributions. Class Z shares are sold at net asset value with no Rule 12b-1 fees. Class Z shares have limited eligibility and the investment minimum requirement may vary. Please see fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. Performance results reflect any voluntary waivers or reimbursement of fund expenses by the advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Class A is a newer class of shares. Its performance information includes returns of the fund's class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class Z shares were initially offered on March 5, 1984, and class A shares were initially offered on July 31, 2000. Class B and class C are newer classes of shares. Their performance information includes returns of the fund's class A shares from July 31, 2000 (class A's inception) to July 15, 2002 (inception of newer classes of shares). Their performance information prior to July 31, 2000 includes returns of the fund's class Z shares (the oldest existing fund class). These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between class A or class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class Z shares were initially offered on March 5, 1984, class A shares were initially offered on July 31, 2000, and class B and class C shares were initially offered on July 15, 2002. 1 Understanding Your Expenses - Columbia High Yield Municipal Fund Shareholder expense example As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare this cost with the continuing costs of investing in other mutual funds. Analyzing your fund's expenses by share class To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in each share class during the period. The information in the following table is based on an initial investment of $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated using the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Estimating your actual expenses To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period: .. For shareholders who receive their account statements from Columbia Management Services, Inc., your account balance is available online at www.columbiafunds.com or by calling Shareholder Services at 800.345.6611. .. For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance. 1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your share class. You will find this number in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. 01/01/06 - 06/30/06 Account value Account value Fund's at the at the Expenses paid annualized beginning of the end of the during the expense period ($) period ($) period ($) ratio (%) Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,014.78 1,020.53 4.30 4.31 .86 Class B 1,000.00 1,000.00 1,011.01 1,016.81 8.03 8.05 1.61 Class C 1,000.00 1,000.00 1,011.75 1,017.55 7.28 7.30 1.46 Class Z 1,000.00 1,000.00 1,015.77 1,021.52 3.30 3.31 .66 Expenses paid during the period are equal to the annualized expense ratio for the share class, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the distributor and transfer agent not waived a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only continuing costs of investing in the fund and do not reflect any transaction costs, such as sales charges or redemption or exchange fees. Therefore, the hypothetical examples provided will not help you determine the relative total costs of owning different funds. If these transaction costs were included, your costs would have been higher. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transaction costs, such as sales charges or redemption or exchange fees. 2 Economic Update - Columbia High Yield Municipal Fund The US economy grew at a solid but uneven pace during the 12-month period that began July 1, 2005 and ended June 30, 2006. Gross domestic product (GDP) expanded at an estimated annualized rate of approximately 3.5% as job growth provided support for consumer spending. Rising profits freed up cash for business spending, which picked up during the period. Personal income rose. Yet, these overall measures masked a host of challenges, which led to considerable volatility during the 12-month period. Late last summer, hurricanes Katrina and Rita devastated the Gulf Coast, disrupting the flow of energy products and leaving millions of Americans without homes or jobs. Consumer confidence plummeted in the wake of the storms. The impact on the labor market was actually less than anticipated. However, economic growth fell to a mere 1.7% in the fourth quarter. The economy regained considerable momentum early in 2006. GDP growth rebounded to 5.6%. Job growth resumed at a healthy pace, and consumer confidence rebounded. Yet, the once strong housing market has shown signs of slowing. Inflation edged higher as record-high energy prices took a bigger bite out of household budgets. Consumer spending growth edged lower in the final months of the period, and economic growth declined to 2.5% for the last quarter of the reporting period. Eight short-term rate hikes -- and more to come? The Federal Reserve Board (the Fed) raised the federal funds rate, a key short-term rate, from 3.25% to 5.25% in eight consecutive one-quarter point increases. In the wake of hurricanes Katrina and Rita, some market observers speculated that the Fed might curtail its rate hikes. However, outgoing Fed chairman Greenspan indicated that inflation was a greater concern than the sustainability of economic growth, and the Fed, under new chairman Ben Bernanke, continued to raise short-term interest rates through the end of the period. After a solid start, bond market sputters The US bond market headed downward during the period as interest rates moved higher across the maturity spectrum. The yield on the 10-year US Treasury note, a bellwether for the bond market, rose more than one full percentage point and ended the period at 5.14%. In this environment, the Lehman Brothers Aggregate Bond Index returned negative 0.81% for the 12-month period. High-yield bonds led the fixed income markets. The Merrill Lynch US High Yield, Cash Pay Only Index returned 4.65%. Stocks moved higher Despite bouts of volatility, the S&P 500 Index -- a broad measure of large company stock market performance -- returned a respectable 8.63% for this reporting period. Small- and mid-cap stocks did even better. The Russell 2000 Index returned 14.58% while the Russell Midcap Index returned 13.66%. Energy stocks led the US stock market as commodity prices continued to climb. Foreign stock markets generally did better than the US market. The MSCI EAFE Index, which tracks stock market performance in industrialized countries outside the United States, returned 26.56%. The Russell Midcap Index measures the performance of the 800 smallest companies in the Russell 1000 Index, which represent approximately 25% of the total market capitalization of the Russell 1000 Index. The Lehman Brothers Aggregate Bond Index is a market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar denominated non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. The Merrill Lynch US High Yield, Cash Pay Only Index tracks the performance of non-investment-grade corporate bonds. The S&P 500 Index is an unmanaged index that tracks the performance of 500 widely held, large-capitalization US stocks. The Russell 2000 Index measures the performance of the 2,000 smallest companies in the Russell 3000 Index, which represents approximately 8% of the total market capitalization of the Russell 3000 Index. The MSCI EAFE index is a free float-adjusted market capitalization Index that is designed to measure developed market equity performance, excluding the US and Canada. Unlike mutual funds, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index.

For the 12-month period ended June 30, 2006, the fund's class A shares returned 3.39% without sales charge. .. In general, high-yield bonds held up better than investment-grade bonds as the bond market came under pressure from rising interest rates. .. Airline bonds were among the fund's best performers. However, we believe the fund had less exposure than competing funds to the airline industry, which accounted for much of the small difference in return between the fund and the average return of its peers.

For the 12-month period ended June 30, 2006, class A shares of Columbia High Yield Municipal Fund returned 3.39% without sales charge. The fund did better than its benchmark, the Lehman Brothers Municipal Bond Index, which returned 0.89% for the same period. The fund's performance was just short of the 3.79% average return of its peer group, the Lipper High Yield Municipal Debt Funds Category. Selected bonds enjoyed strong returns because of improved credit ratings and certain airline bonds helped bolster the fund's performance. However, we believe that the fund had less exposure than competing funds to the airline industry, which detracted slightly from performance relative to its peer group, as did its overall focus on higher quality high-yield bonds. A positive environment for high-yield municipals Positive economic growth improved the credit outlook for many high-yield issuers during the period and aided the overall performance of high-yield municipal bonds. As a result, the difference between yields on lower and higher quality debt narrowed. Strong demand from investors searching for added yield also aided performance. Gains from airline and assisted living facility bonds Airline bonds were among the top contributors to the fund's performance. Airline issues rallied as improved operating results attracted investors. US Airways bonds, issued by the Charlotte, North Carolina Airport Authority (.40% of net assets), did especially well after emerging from bankruptcy protection. However, we believe that the fund had less exposure to airlines than the average fund in its peer group, which detracted from relative performance. The airline industry's municipal bonds enjoyed gains of between 15% and 50% while the bond market, in general, declined. Elsewhere in the portfolio, the price of bonds issued by a Roseville, MN (.20% of net assets) assisted living facility increased approximately 18% due to credit improvement. And several of the fund's positions were either refunded or called at par. One such holding was Attic Angel, a bond that was refunded -- the issuer issued new bonds paying a lower interest rate and pledged the proceeds of the new bonds as security for the older bonds. In the process, the older bond's price rose as it went from non-rated to a AAA rating. Issue-specific disappointments Bonds issued by Northwest Parkway (.40% of net assets) for the construction of a toll road northwest of Denver were a disappointment. These bonds lost ground when the issuer tried unsuccessfully to refund, or restructure, its debt to help with cash flow weakness. In addition, Northwest Airlines bonds (no longer in the portfolio) declined in reaction to news that the airline had challenged the lease agreement at its Minneapolis hub. Lower-coupon bonds, which tend to be longer duration, also underperformed. Duration is a measure of a bond's sensitivity to changing interest rates; longer duration bonds tend to be more sensitive to interest rate moves. Looking ahead At the end of the period, with signs of a slowing economy and expectations that the Fed could be close to ending its short-term interest rate hikes, the fund had a slightly longer duration than its peers and a tilt toward higher quality high-yield bonds. We believe that longer-term bonds could do well in an environment of slower growth and stabilized rates. However, we don't expect a significant rally until there are clear signs that inflation is headed lower. We believe that higher quality bonds could do well if the yield difference between higher and lower quality bonds widens. In our estimation, yield spreads may not narrow much further; however, there is also no indication that they are likely to widen in the near term. Maureen G. Newman Maureen G. Newman has managed the Columbia High Yield Municipal Fund since November 1998 and has been with the advisor or its predecessors or affiliate organizations since 1996. 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. Investments in high-yield or "junk" bonds offer the potential for higher income than investments in investment-grade bonds, but they also have 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. Lipper Inc., a widely respected data provider in the industry, calculates an average total return (assuming reinvestment of distributions) for mutual funds with investment objectives similar to those of the Fund. Lipper makes no adjustment for the effect of sales loads. 4 Fund Profile - Columbia High Yield Municipal Fund Quality breakdown as of 06/30/06 (%) AAA 28.4 AA 6.2 A 11.9 BBB 19.6 BB 3.3 B 1.5 CCC 0.4 Non-rated 26.8 Cash equivalent 1.9 Maturity breakdown as of 06/30/06 (%) 0-1 years 0.8 1-3 years 4.4 3-5 years 2.8 5-7 years 4.1 7-10 years 5.1 10-15 years 19.6 15-20 years 16.6 20-25 years 12.8 25 years and over 31.9 Cash equivalent 1.9 Performance data quoted represents past performance and current performance may be lower or higher.

See Accompanying Notes to Financial Statements. 45 Notes to Financial Statements - Columbia High Yield Municipal Fund (June 30, 2006) Note 1. Organization Columbia High Yield Municipal Fund (the "Fund"), a series of Columbia Funds Series Trust I, formerly Columbia Funds Trust IX (the "Trust"), is a diversified portfolio. The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. Investment Goal The Fund seeks a high level of total return consisting of current income exempt from federal income tax and opportunities for capital appreciation. Fund Shares The Fund may issue an unlimited number of shares and offers four classes of shares: Class A, Class B, Class C and Class Z. Each share class has its own sales charge and expense structure. Class A shares are subject to a maximum front-end sales charge of 4.75% based on the amount of initial investment. Class A shares purchased without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% contingent deferred sales charge ("CDSC") if the shares are sold within twelve months of the time of the purchase. Class B shares are subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will convert to Class A shares in a certain number of years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class Z shares, as described in the Fund's prospectus. 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 other 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. 46 Columbia High Yield Municipal Fund (June 30, 2006) Futures Contracts The Fund may invest in futures contracts 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. 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 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 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. Swap Contracts The Fund may engage in swap transactions such as interest rate, total return, index or currency swaps, consistent with its investment objective and policies to obtain a desired return at a lower cost than if the Fund had invested directly in the asset that yielded the desired return. Swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest or total return throughout the lives of the agreements. The interest to be paid or received on swaps is included in net realized gain/(loss) on investments. Unrealized gains are reported as an asset and unrealized losses are reported as a liability on the Statements of assets and liabilities. A realized gain or loss is recorded upon termination of swap agreements and is equal to the difference between the Fund's basis in the swap and the proceeds from (or cost of) the closing transaction. Swap agreements are stated at fair value. Notional principal amounts are used to express the extent of involvement in these transactions, but the amounts potentially subject to credit risk are much smaller. If there is a default by the counterparty to a swap contract, a Fund will be limited to contractual remedies pursuant to the agreements related to the transaction. There is no assurance that the swap contract counterparties will be able to meet their obligations pursuant to the swap contracts or that, in the event of default, a Fund will succeed in pursuing contractual remedies. A Fund thus assumes the risk that it may be delayed in or prevented from obtaining payments owed to it pursuant to the swap contracts. The use of derivative instruments involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statements of assets and liabilities. Delayed Delivery Securities The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a "when-issued" basis. 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. The Fund identifies cash or liquid portfolio securities in its records in an amount equal to the delayed delivery commitment. 47 Columbia High Yield Municipal Fund (June 30, 2006) 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 debt securities. Dividend income is recorded on the ex-date. Determination of Class Net Asset Values All income, expenses (other than class-specific expenses, as shown on the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis for purposes of determining the net asset value of each class. Income and expenses are allocated to each class based on the settled shares method, while realized and unrealized gains (losses) are allocated based on the relative net assets of each class. 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 Dividends from net investment income are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. 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 June 30, 2006, permanent book and tax basis differences resulting primarily from differing treatments for discount accretion/premium amortization on debt securities, capital loss carry forwards expired and market discount reclassifications were identified and reclassified among the components of the Fund's net assets as follows: Accumulated Accumulated Net Investment Net Realized Income Loss Paid-In Capital $(115,600) $6,049,573 $(5,933,973) 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 June 30, 2006 and June 30, 2005 was as follows: June 30, 2006 June 30, 2005 Distributions paid from: Tax-Exempt Income $30,364,551 $24,945,098 Ordinary Income* 82,635 41,919 Long-Term Capital Gains -- -- *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of June 30, 2006 the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Undistributed Net Unrealized Tax-Exempt Ordinary Long-term Appreciation Income Income Capital Gains (Depreciation)* $2,890,064 $-- $-- $14,944,398 *The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to discount accretion/premium amortization on debt securities. Unrealized appreciation and depreciation at June 30, 2006, based on cost of investments for federal income tax purposes, was: Unrealized appreciation $22,738,895 Unrealized depreciation (7,794,497) Net unrealized appreciation $14,944,398 48 Columbia High Yield Municipal Fund (June 30, 2006) The following capital loss carryforwards, determined as of June 30, 2006, 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 Expiration Capital Loss Carryforward 2007 1,931,613 2008 2,738,332 2009 1,928,565 2010 1,780,434 2011 697,947 2012 1,587,432 2013 5,621,572 2014 466,991 Total $16,752,886 Of the capital loss carryforwards attributable to the Fund, $6,846,435 ($1,931,613 will expire on June 30, 2007, $2,738,332 will expire on June 30, 2008, $1,081,414 will expire on June 30, 2009 and $1,095,076 will expire on June 30, 2010) was obtained in the merger with Liberty High Yield Municipal Fund. Utilization of these losses could be subject to limitations imposed by the Internal Revenue Code. Capital loss carryforwards of $5,933,974 expired during the year ended June 30, 2006. Any capital loss carryforwards acquired as part of a merger that are permanently lost due to provisions under Internal Revenue Code are included as being expired. Expired capital loss carryforwards are recorded as a reduction of paid-in capital. Under current tax rules, certain currency (and capital) losses realized after October 31 may be deferred and treated as occurring on the first day of the following fiscal year. As of June 30, 2006, post-October capital losses of $1,689,518 attributed to security transactions were deferred to July 1, 2006. In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement 109 (the "Interpretation"). This Interpretation is effective for fiscal years beginning after December 15, 2006 and is to be applied to tax positions upon initial adoption. This Interpretation prescribes a minimum recognition threshold and measurement method for the financial statement recognition of tax positions taken or expected to be taken in a tax return and also requires certain expanded disclosures. Management has recently begun to evaluate the application of this Interpretation to the Fund and has not at this time quantified the impact, if any, resulting from the adoption of this Interpretation on the Fund's financial statements.

Prior to September 30, 2005, Columbia Management Advisors, Inc. was investment advisor to 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 based on the Fund's average daily net assets at the following annual rates: Average Daily Net Assets Annual Fee Rate First $100 million 0.450% $100 million to $200 million 0.425% Over $200 million 0.400% For the year ended June 30, 2006, the Fund's effective investment advisory fee rate was 0.41% of the Fund's average daily net assets. Administration Fee Columbia provides administrative and other services to the Fund for a monthly administration fee based on the Fund's average daily net assets at the following annual rates: Average Daily Net Assets Annual Fee Rate First $100 million 0.150% $100 million to $200 million 0.125% Over $200 million 0.100% For the year ended June 30, 2006, the Fund's effective administration fee rate was 0.11% of the Fund's average daily net assets. 49 Columbia High Yield Municipal Fund (June 30, 2006) 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 State Street the total fees collected under the pricing and bookkeeping agreement. 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 daily net assets for the month; provided that during any 12-month period, the aggregate fee, exclusive of out-of-pocket expenses and charges, 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 daily 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 June 30, 2006, the effective pricing and bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was 0.033% of the Fund's average daily net assets. Transfer Agent Fee Columbia Management Services, Inc. (the "Transfer Agent"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, provides shareholder services to the Fund. On August 22, 2005, Columbia Funds Services, Inc. was renamed Columbia Management Services, Inc. The Transfer Agent has contracted with Boston Financial Data Services ("BFDS") to serve as sub-transfer agent. The Transfer Agent is entitled to receive a fee for its services, paid monthly, at the annual rate of $17.00 per open account plus sub-transfer agent fees (exclusive of BFDS fees) calculated based on assets held in omnibus accounts and intended to recover the cost of payments to third parties for services to those accounts. The Transfer Agent may also retain, as additional compensation for its services, fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcript fees due the Transfer Agent from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts the Transfer Agent maintains in connection with its services to the Fund. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. Prior to April 1, 2006, the Transfer Agent received a fee, paid monthly, at the annual rate of $15.23 per open account and prior to November 1, 2005, the annual rate was $34.00. The Transfer Agent also received reimbursement for certain out-of-pocket expenses. For the period September 1, 2005 through October 31, 2005, the Transfer Agent voluntarily waived fees of $9,921 for the Fund. For the year ended June 30, 2006, the Fund's effective transfer agent fee rate, inclusive of out-of-pocket expenses and net of fee waivers, was 0.03%. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and a wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. On August 22, 2005, Columbia Funds Distributor, Inc. was renamed Columbia Management Distributors, Inc. For the year ended June 30, 2006, the Distributor has retained net underwriting discounts of $13,298 on sales of the Fund's Class A shares and received net CDSC of $65,002 and $1,561 on Class B and Class C share redemptions, respectively. The Fund has adopted a Rule 12b-1 plan (the "Plan") which requires the payment of a monthly service fee to the Distributor. The service fee is equal to 0.20% annually of the average daily net assets attributable to Class A, Class B and Class C shares. The Plan also requires the payment of a monthly distribution fee to the Distributor at the annual rate of 0.75% of the average daily net assets attributable to Class B and Class C shares only. The Distributor has voluntarily agreed to waive a portion of the Class C share distribution fee so that it will not exceed 0.60% annually. The CDSC and the distribution fees received from the Plan are used principally as repayment to the Distributor for amounts paid by the Distributor to dealers who sold such shares. 50 Columbia High Yield Municipal Fund (June 30, 2006) 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. 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, will pay its pro-rata share of the expenses associated with the Chief Compliance Officer position. The Fund's fee for the Office of 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 June 30, 2006, the Fund paid $2,514 to Columbia for such services. This amount is included in "Other expenses" on the Statement of Operations. Note 5. Purchases and Sales of Securities For the year ended June 30, 2006, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $250,162,734 and $83,260,600, respectively. Note 6. Line of Credit The Fund and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit provided by State Street Bank and Trust Company. Borrowings are used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. For the year ended June 30, 2006, the Fund did not borrow under this arrangement. Note 7. Shares of Beneficial Interest As of June 30, 2006, the Fund had a shareholder that held 59.30% of the shares outstanding whose shares were beneficially owned by participant accounts over which Bank of America and/or its affiliates had either sole or joint investment discretion. Note 8. Disclosure of Significant Risks and Contingencies Municipal Bond Tax Status The Fund purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued. 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 Services, Inc., except for Radian Asset Assurance, Inc. which is rated Aa3. At June 30, 2006, private insurers who insured greater than 5% of the total investments of the Fund were as follows: Insurer % of Total Investment MBIA Insurance Corp. 8.9% Ambac Assurance Corp. 5.9 Financial Guaranty Insurance Co. 5.2 Geographic Concentration The Fund has greater than 5% of its total investments at June 30, 2006 invested in debt obligations issued by the states of California, Florida, Massachusetts, New York and Texas and their respective political subdivisions, agencies and public authorities. The Fund is more susceptible to economic 51 Columbia High Yield Municipal Fund (June 30, 2006) and political factors adversely affecting issuers of the states' 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. Industry Focus The Fund may focus its investments in certain industries, subjecting it to greater risk than a fund that is more diversified. 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 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 management fees for certain Columbia Funds (including the former Nations Funds) and other mutual funds 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 developed by an independent distribution consultant and approved by the SEC. The independent distribution consultant has been in consultation with the staff of the SEC and has submitted a proposed plan of distribution. The SEC has not yet approved a final plan of distribution. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds. 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. On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common 52 Columbia High Yield Municipal Fund (June 30, 2006) law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law. On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds Trusts and the Columbia Acorn Trusts. As to Columbia and the Distributor, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 ("ICA") and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed. On March 21, 2005, a purported class action was filed 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. On April 4, 2006 the plaintiffs and the Columbia defendants named in the MDL, including the Columbia Funds, entered into a term sheet containing the principal terms of a stipulation of settlement that would settle all Columbia-related claims in the MDL described above, including the CDSC Lawsuit. On April 6, 2006, the U.S. District Court for the District of Maryland stayed all actions with respect to these Columbia-related claims. 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 purpose. 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 and this appeal is pending. For the year ended June 30, 2006, Columbia has assumed $8,045 of legal, consulting services and Trustees' fees incurred by the Fund in connection with these matters. 53 Report of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia High Yield 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 Columbia High Yield Municipal Fund (the "Fund") (a series of Columbia Funds Series Trust I, formerly Columbia Funds Trust IX) at June 30, 2006, the results of its operations for the year then ended and, the changes in its net assets and the financial highlights for the years ended June 30, 2006 and 2005, 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 audits 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 June 30, 2006 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for the three years in the period ended June 30, 2003 were audited by other independent accountants whose report dated August 19, 2003 expressed an unqualified opinion on those statements. PricewaterhouseCoopers LLP Boston, Massachusetts August 25, 2006 54 Unaudited Information - Columbia High Yield Municipal Fund Federal Income Tax Information 100% of the distributions from net investment income will be treated as exempt income for federal income tax purposes.

(e)(1) Audit Committee Pre-Approval Policies and Procedures The registrant's Audit Committee is required to pre-approve the engagement of the registrant's independent accountants to provide audit and non-audit services to the registrant and non-audit services to its investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) or any entity controlling, controlled by or under common control with such investment adviser that provides ongoing services to the registrant ("Adviser Affiliates"), if the engagement relates directly to the operations and financial reporting of the registrant. The Audit Committee has adopted a Policy for Engagement of Independent Accountants for Audit and Non-Audit Services ("Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit-related, tax and other services to the registrant (collectively "Fund Services"); (ii) non-audit services to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and Adviser Affiliates, if the engagement relates directly to the operations or financial reporting of a Fund (collectively "Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and Adviser Affiliates. Unless a type of service receives general pre-approval under the Policy, it requires specific pre-approval by the Audit Committee if it is to be provided by the independent accountants. Pre-approval of non-audit services to the registrant, the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and Adviser Affiliates may be waived provided that the "de minimis" requirements set forth under paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are met. Under the Policy, the Audit Committee may delegate pre-approval authority to any pre-designated member or members who are Independent Trustees/Directors. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre-approval of services performed by the independent accountants may not be delegated to management. The Policy requires the Fund Treasurer and/or Director of Board Administration to submit to the Audit Committee, on an annual basis, a schedule of the types of services that are subject to general pre-approval. The schedule(s) provide a description of each type of service that is subject to general pre-approval and, where possible, will provide estimated fee caps for each instance of providing each service. The Audit Committees will review and approve the types of services and review the projected fees for the next fiscal year and may add to, or subtract from, the list of general pre-approved services from time to time based on subsequent determinations. That approval acknowledges that the Audit Committee is in agreement with the specific types of services that the independent accountants will be permitted to perform. The Fund Treasurer and/or Director of Board 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, 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. ***** (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 June 30, 2006 and June 30, 2005 was zero. (f) Not applicable. (g) The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's 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 for the fiscal years ended June 30, 2006 and June 30, 2005 are approximately as follows: 2006 2005 ---- ---- $376,800 $110,300 (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.

Item 11. Controls and Procedures.
