Wilson President, Columbia Funds Dear Shareholder: Investing is a long-term process and we are pleased that you have chosen to include the Columbia family of funds in your overall financial plan. Your financial advisor can help you establish an appropriate investment portfolio and periodically review that portfolio. A well balanced portfolio is one of the keys to successful long-term investing. Your portfolio should be diversified across different asset classes and market segments and your chosen asset allocation should be appropriate for your investment goals, risk tolerance and time horizons. However, creating an investment strategy is not a one-step process. From time to time, you'll need to re-evaluate your strategy to determine whether your investment needs have changed. Most experts recommend giving your portfolio a "check-up" every year. As you begin your portfolio check-up, consider whether you have experienced any major life events since the last time you assessed your portfolio. You may need to tweak your strategy if you have: .. Gotten married or divorced .. Added a child to your family .. Made a significant change in employment .. Entered or moved significantly closer to retirement .. Experienced a serious illness or death in the family .. Taken on or paid off substantial debt It's important to remember that over time, performance in different market segments will fluctuate. When the stock market is up, the bond market is typically down -- and vice versa. These shifts can cause your portfolio balance to drift away from your chosen asset allocation. A periodic portfolio check-up can help make sure your portfolio stays on track. Remember that asset allocation does not ensure a profit or guarantee against loss. You'll also want to analyze the individual investments in your portfolio. Of course, performance should be a key factor in your analysis, but it's not the only factor to consider. Make sure the investments in your portfolio line up with your overall objectives and risk tolerance. Be aware of changes in portfolio management and pay special attention to any funds that have made significant shifts in their investment strategy. We hope this information will help you, in working with your financial advisor, to stay on track to reach your investment goals. Thank you for your business and for your continued confidence in Columbia Funds. Sincerely, /s/ Christopher L. Wilson Christopher L. Wilson President, Columbia Funds Economic Update - Columbia World Equity Fund Summary For the 12-month period ended March 31, 2007 . The world's major stock markets moved higher, boosted by generally solid economic growth. Foreign markets were generally stronger than the US market, as measured by the MSCI EAFE Index. MSCI World MSCI EAFE Index Index [GRAPHIC] [GRAPHIC] 15.44% 20.20% The Morgan Stanley Capital International (MSCI) World Index tracks the performance of global stocks. The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. 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. World economic growth advanced at a healthy pace during the 12-month period that began April 1, 2006 and ended March 31, 2007. For 2006, world gross domestic product was estimated at 3.6%. In 2007, growth is expected to slow somewhat to 3.0%, primarily because of slower growth in the United States, where a weak housing market weighed on the economy throughout the period. Core inflation remained above the comfort level of central banks in most of the world's major economies, and most central banks raised short-term interest rates in an effort to control inflationary pressures during the period. Slower growth for euro zone economies In the euro zone, the economy expanded 2.75% in 2006, as strong external trade boosted growth. However, the economy got off to a slower start in 2007, as both export demand and private consumption showed signs of weakening. The European Central Bank (ECB) continued to raise its key policy rate in quarter-point increments throughout the period, reflecting continued concerns about inflation. Capacity utilization is tight, as many factories are close to their limits; wages have increased; and money supply growth reached a record high in January--lending support to the ECB's policy decisions. Japan's economy loses some momentum Japan's economy maintained a slow but relatively steady pace of growth throughout the period. However, it lost momentum in the early months of 2007 as exports cooled and consumer spending remained weak. Although inflation is negligible, the Bank of Japan appears set to lift interest rates later this year. Elsewhere in Asia, the economies of South Korea and Taiwan also showed signs of slowing as external demand for technology-related exports decelerated sharply in the final months of 2006. China continues to expand at record pace China's economy expanded at an estimated pace of 10.6% in 2006--its fastest growth in over a decade--despite government-induced monetary and administrative measures designed to cool the engines of growth. China's export-driven economy remains vulnerable to slower growth around the globe. Nevertheless, it showed signs of continued expansion at an impressive pace in the early months of 2007. World stock markets reflected economic strength In an environment of generally healthy growth, the world's major stock markets delivered robust returns. The Morgan Stanley Capital International (MSCI) EAFE Index, which measures stock market performance in major developed countries around the world (excluding the United States and Canada), returned 20.20%. Despite a sharp sell-off in February, most markets regained their forward momentum and bounced back with significant strength. The MSCI World Index, which includes the US market, returned 15.44%.

The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower. Performance results reflect any waivers or reimbursements of fund expenses by the investment advisor and/or any of its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. All results shown assume reinvestment of distributions. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. 2 Understanding Your Expenses - Columbia World Equity Fund 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. 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 fees, 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 these costs with the ongoing 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 $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated based on the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. 10/01/06 - 03/31/07 Account value at the Account value at the Expenses paid Fund's annualized beginning of the period ($) end of the period ($) during the period ($) expense ratio (%) - ------------------------------------------------------------------------------------------------- Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,108.00 1,017.70 7.62 7.29 1.45 Class B 1,000.00 1,000.00 1,103.32 1,013.96 11.54 11.05 2.20 Class C 1,000.00 1,000.00 1,103.42 1,013.96 11.54 11.05 2.20 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. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical examples provided may not help you determine the relative total costs of owning shares of different funds. If these transaction costs were included, your costs would have been higher. 3 Portfolio Managers' Report - Columbia World Equity Fund Performance data quoted represents past performance and current performance may be lower or higher.

The fund's benchmark, the MSCI World Index, returned 15.44%./1/ The average return of funds in the fund's peer group, the Morningstar World Stock Category, was 13.97% over the same period./2/ Individual stocks in Japan, Sweden and Germany were largely responsible for the fund's positive return. Stock selection was the primary source of performance Our emphasis on stock selection in companies that we believe should benefit from global economic growth was instrumental in boosting the fund's total return. In Japan, performance was enhanced by Canon, Inc., a leader in digital imaging, and automakers Toyota Motor Corp. and Honda Motor Co., which benefited from growing concerns about fuel efficiency and the trend toward hybrid technology. We took profits in Canon, Inc. and Honda Motor Co. when they reached our target valuations. In Sweden, homebuilder JM AB did well in a robust housing market. Strong growth in gross domestic product in several global economies was a factor in the performance of two other stocks in Sweden--Volvo AB, a manufacturer of trucks and heavy industrial equipment, and SKF AB, a maker of ball bearings, which are fundamental components of most industrial processes. Volvo AB was also positively affected by concerns about controlling automobile emissions, as the company produces some of the best emission control equipment. In Germany, noteworthy results came from chemical company BASF AG and steel producer Salzgitter AG, which rose partly because of higher steel prices. Buoyed by merger and acquisition activity, European utilities generated returns that were more than double the MSCI World Index return. Our position in E.ON AG, an integrated power company in Germany, was helped by this trend. Approximately half of the fund was invested in the United States, where retailer Kohl's Corp. rose on solid profit growth. Federated Department Stores , Inc., also made a positive impact, as the company began to see benefits from its restructuring program. MEMC Electronic Materials, Inc., figured heavily into performance. The company produces wafers for the semiconductor and solar industries. Higher semiconductor prices and growing interest in alternative energy worked to the company's advantage. We held a small number of emerging market stocks, including Taiwan Semiconductor Manufacturing Co., Ltd. and Telefonica O2 Czech Republic AS, both of which produced positive results. Investments in emerging markets are likely to remain a very small part of the fund, but we may add positions as opportunities arise. /1/The Morgan Stanley Capital International (MSCI) World Index tracks the performance of global stocks.

In addition, one of the fund's worst performers was UK-based PartyGaming, an on-line gaming company which suffered because of new legislation that bans US financial institutions from processing on-line gaming transactions. We sold the stock. US financial stocks suffered as the rising number of subprime mortgage defaults affected companies such as AmeriCredit and Radian Group, Inc., which we sold. Our holdings in Merrill Lynch & Co., Inc., also fell short of our expectations. Looking ahead We expect some of the world's equity markets to face some head winds in the period ahead. In the United States, the pace of economic growth has slowed because of the Federal Reserve Board's interest-rate hikes, and there are concerns that the problems in the subprime mortgage market could put additional pressure on economic growth. Because the United States is a large consumer for the rest of the world's goods, a significant slowdown in consumer spending could have negative implications for global growth. In addition, China, another important market for consumer goods, is looking for ways to slow its economy. We believe these factors could lead to short-term volatility in the equity markets. Longer term, however, we think the fundamental backdrop is attractive. Global growth is relatively high and global monetary policy remains relatively favorable, creating positive long-term conditions for the equity markets.

See Accompanying Notes to Financial Statements. 21 Notes to Financial Statements - Columbia World Equity Fund March 31, 2007 Note 1. Organization Columbia World Equity Fund (the "Fund"), a series of Columbia Funds Series Trust I (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 long-term growth by investing primarily in global equities. Fund Shares The Fund may issue an unlimited number of shares and offers three classes of shares: Class A, Class B and Class C. 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 contingent deferred sales charge ("CDSC") of 1.00% 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 eight years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Note 2. Significant Accounting Policies 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. Forward currency exchange contracts are valued at the prevailing forward exchange rates of the underlying currencies. Foreign securities are generally valued at the last sale price on the foreign exchange or market on which they trade. If any foreign share prices are not readily available as a result of limited share activity, the securities are valued at the last sale price of the local shares in the principal market in which such securities are normally traded. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. Occasionally, events affecting the values of such foreign securities and such exchange rates may occur between the times at which they are determined and the close of the customary trading session of the NYSE, which would not be reflected in the computation of the Fund's net asset value. If events materially affecting the values of such foreign securities occur and it is determined that market quotations are not reliable, then these foreign securities will be valued at their fair value using procedures approved by the Board of Trustees. The Fund may use a systematic fair valuation model provided by an independent third party to value securities principally traded in foreign markets in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and the time for valuation. 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. 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 22 Columbia World Equity Fund March 31, 2007 procedures established by and under the general supervision of the Board of Trustees. In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is evaluating the impact the application of SFAS 157 will have on the Fund's financial statement disclosures. 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. Forward Foreign Currency Exchange Contracts Forward foreign currency exchange contracts are agreements to exchange one currency for another at a future date at a specified price. These contracts are used to minimize the exposure to foreign exchange rate fluctuations during the period between trade and settlement date. The Fund may utilize forward foreign currency exchange contracts in connection with the settlement of purchases and sales of securities. The Fund may also enter into these contracts to hedge certain other foreign currency denominated assets. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell are used to hedge the Fund's investments against currency fluctuations. Forward currency contracts are valued daily at the current exchange rate of the underlying currency, resulting in unrealized gains (losses) which become realized at the time the foreign currency contracts are closed or mature. Realized and unrealized gains (losses) arising from such transactions are included in net realized and unrealized gains (losses) on foreign currency transactions. The use of forward currency contracts does not eliminate fluctuations in the prices of the Fund's portfolio securities. Although the maximum potential loss from such contracts is the aggregate face value in U.S. dollars at the time the contract was opened, exposure is typically limited to the change in value of the contract (in U.S. dollars) over the period it remains open. The Fund could also be exposed to risk if the counterparties of the contracts are unable to fulfill the terms of the contracts. Repurchase Agreements The Fund may engage in repurchase agreement transactions with institutions that Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy. The Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Columbia is responsible for determining that 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. 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. 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 in the Statement of Operations. 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 23 Columbia World Equity Fund March 31, 2007 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. Indemnification In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Fund's organizational documents and by contract, the trustees and officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these representations, warranties and indemnities to be minimal. 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 March 31, 2007, permanent book and tax basis differences resulting primarily from differing treatments for foreign currency transactions were identified and reclassified among the components of the Fund's net assets as follows: Overdistributed Accumulated Net Investment Net Realized Income Gain Paid-In Capital $(61,793) $(339,734) $401,527 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 March 31, 2007 and March 31, 2006 was as follows: March 31, 2007 March 31, 2006 Distributions paid from: Ordinary Income* $2,012,765 $355,963 Long-Term Capital Gains 2,637,207 -- *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of March 31, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Net Ordinary Long-Term Unrealized Income Capital Gains Appreciation* $1,515,270 $3,512,454 $15,077,050 *The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to passive foreign investment company mark to market. Unrealized appreciation and depreciation at March 31, 2007, based on cost of investments for federal income tax purposes were: Unrealized appreciation $15,870,029 Unrealized depreciation (792,979) Net unrealized appreciation $15,077,050 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 No. 109 (the "Interpretation"). This Interpretation is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 24 Columbia World Equity Fund March 31, 2007 2006 and is to be applied to open 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 is evaluating 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, an indirect, wholly-owned subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to the Fund. 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 $1 billion 0.40% Over $1 billion 0.35% For the year ended March 31, 2007, the Fund's effective investment advisory fee rate was 0.40% of the Fund's average daily net assets. Administration Fee Columbia provides administrative and other services to the Fund for a monthly administration fee at the annual rate of 0.25% of the Fund's average daily net assets. Pricing and Bookkeeping Fees Effective December 15, 2006, the Fund entered into a financial reporting services agreement with State Street Bank & Trust Company ("State Street") and Columbia (the "Financial Reporting Services Agreement") pursuant to which State Street provides financial reporting services to the Fund. Also effective December 15, 2006, the Fund entered into an accounting services agreement with State Street and Columbia (collectively with the Financial Reporting Services Agreement, the "State Street Agreements") pursuant to which State Street provides accounting services to the Fund. Under the State Street Agreements, the Fund pays State Street an annual fee of $38,000 paid monthly plus an additional monthly fee based on an annualized percentage rate of average daily net assets of the Fund for the month. Under the State Street Agreements, the combined fee payable to State Street by the Fund will not exceed $140,000 annually. The Fund also reimburses State Street for certain out-of-pocket expenses. Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping Oversight and Services Agreement (the "Services Agreement") with Columbia. Under the Services Agreement, Columbia provides services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides oversight of the accounting and financial reporting services provided by State Street. Under the Services Agreement, the Fund reimburses Columbia for out-of-pocket expenses and direct internal costs relating to accounting oversight and for services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002. Prior to December 15, 2006, Columbia was responsible for providing pricing and bookkeeping services to the Fund under a pricing and bookkeeping agreement. Under its pricing and bookkeeping agreement with the Fund, Columbia was entitled to receive an annual fee at the rate structure described above under the State Street Agreements. Under separate agreements between Columbia and State Street, Columbia delegated certain functions to State Street. As a result of the delegation, the total fees payable under the pricing and bookkeeping agreement (other than certain reimbursements paid to Columbia and discussed below) were paid to State Street. The Fund also reimbursed 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 March 31, 2007, the effective pricing and bookkeeping fee rates for the Fund, inclusive of out-of-pocket expenses, was 0.084% 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 and has contracted with Boston Financial Data Services 25 Columbia World Equity Fund March 31, 2007 ("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 reimbursement of certain sub-transfer agent fees paid by the Transfer Agent (exclusive of BFDS fees) calculated based on assets held in omnibus accounts and intended to recover the cost of payments to other parties (including affiliates of BOA) for services to those accounts. The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursements for such fees from the Fund. 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. For the year ended March 31, 2007, the Fund's effective transfer agent fee rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was 0.23% of the Fund's average daily net assets. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. For the year ended March 31, 2007, the Distributor has retained net underwriting discounts of $30,912 on sales of the Fund's Class A shares and net CDSC fees of $201, $15,816 and $520 on Class A, Class B and Class C share redemptions, respectively. The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Fund. 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. This arrangement may be modified or terminated by the distributor at any time. 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 in the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. Fees Paid to Officers and Trustees All officers of the Fund are employees of Columbia or its affiliates and, with the exception of the Fund's Chief Compliance Officer, receive no compensation from the Fund. The Board of Trustees has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund, along with other affiliated funds, pays its pro-rata share of the expenses associated with the Chief Compliance Officer. The Fund's expenses for the Chief Compliance Officer will not exceed $15,000 per year. The Fund's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Fund's assets. Other Columbia provides certain services to the Fund related to the requirements of the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund paid $2,875 to Columbia for such services. This amount is included in "Other expenses" in the Statement of Operations. Note 5. Portfolio Information For the year ended March 31, 2007, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $80,751,487 and $93,898,499, respectively. Note 6. Shares of Beneficial Interest As of March 31, 2007, one shareholder held 5.1% of the shares outstanding. Subscription and redemption activity of this account may have a significant effect on the operations of the Fund. Note 7. Line of Credit The Trust and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit and 26 Columbia World Equity Fund March 31, 2007 a $150,000,000 uncommitted, unsecured line of credit, both provided by State Street. Borrowings are available for temporary or emergency purposes. Interest on the committed line of credit is charged to each participating fund based on the fund's 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 committed line of credit. Interest on the uncommitted line of credit is charged to each participating fund based on the fund's borrowings at a variable rate per annum equal to the Federal Funds Rate plus a spread, as determined and quoted by State Street at the time of the request for a loan. A one-time structuring fee of $30,000 is also accrued and apportioned to each fund participating in the uncommitted line of credit based on the average net assets of the participating funds. In addition, if the uncommitted line of credit is extended for an additional period, an annual administration fee of $15,000 will be charged and apportioned among the participating fund. The commitment fee and structuring fee are included in "Other expenses" in the Statement of Operations. For the year ended March 31, 2007, the Fund did not borrow under this arrangement. Note 8. Redemption Fees The Fund imposes a 2.00% redemption fee to shareholders of the Fund who redeem shares within 60 days of purchase. Redemption fees, which are retained by the Fund, are accounted for as an addition to paid-in capital and are allocated to each class proportionately for purposes of determining the net asset value of each class. For the year ended March 31, 2007, the redemption fees for the Class A, Class B, and Class C shares of the Fund amounted to $1,079, $135, and $17, respectively. Note 9. Disclosure of Significant Risks and Contingencies Foreign Securities There are certain additional risks involved when investing in foreign securities that are not inherent with investments in domestic securities. These risks may involve foreign currency exchange rate fluctuations, adverse political and economic developments and the possible prevention of currency exchange or other foreign governmental laws or restrictions. In addition, the liquidity of foreign securities may be more limited than that of domestic securities. Investments in emerging market countries are subject to additional risk. The risk of foreign investments is typically increased in less developed countries. These countries are also more likely to experience high levels of inflation, deflation or currency devaluation which could hurt their economies and securities markets. Sector Focus Companies that are in different but closely related industries are sometimes described as being in the same sector. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector. During such times, the Fund will have greater exposure to the economic and market events affecting such sector than if it were more broadly invested across multiple sectors. 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") on matters relating to mutual fund trading. The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". 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 27 Columbia World Equity Fund March 31, 2007 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 that was developed by an independent distribution consultant and approved by the SEC on April 6, 2007. 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 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 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. 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 were not dismissed. On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that certain conduct, including market timing, entitled Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was removed to federal court in Massachusetts and the federal Judicial Panel 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 settlement is subject to court approval. In 2004, the Columbia Funds' adviser and distributor and certain affiliated entities and individuals 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. Certain Columbia Funds were named as nominal defendants. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment in favor of the defendants. The plaintiffs appealed to the United States Court of Appeals for the First Circuit on December 30, 2005. A stipulation and settlement agreement dated January 19, 2007 was filed in the First Circuit on February 14, 2007, with a joint stipulation of dismissal and 28 Columbia World Equity Fund March 31, 2007 motion for remand to obtain district court approval of the settlement. That joint motion was granted and the appeal was dismissed. On March 6, 2007, the case was remanded to the District Court. On May 11, 2007, the District Court entered a preliminary approval order which granted preliminary approval of the settlement. A final settlement hearing, at which the District Court will determine whether the proposed settlement should be finally approved and the action dismissed on the merits with prejudice, is scheduled for September 18, 2007. The terms of the settlement, if finally approved, will require payments by the funds' adviser and/or its affiliates, including payment of plaintiffs' attorneys' fees and notice to class members. In the event that the settlement is not finally approved, the plaintiffs may elect to go forward with their appeal and no opinion is expressed regarding the likely outcome or financial impact of such an appeal on any fund. 29 Report of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia World Equity 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 World Equity Fund (the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2007 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP Boston, Massachusetts May 25, 2007 30 Unaudited Information - Columbia World Equity Fund Federal Income Tax Information For the fiscal year ended March 31, 2007, the amount of long-term capital gains designated by the Fund was $5,760,407. Foreign taxes paid during the fiscal year ended March 31, 2007, amounting to $142,779 ($0.02 per share) are expected to be passed through to shareholders as 100% allowable foreign tax credits on Form 1099-DIV for the year ending December 31, 2007. Gross income derived from sources within foreign countries amounted to $1,312,983 ($0.21 per share) for the fiscal year ended March 31, 2007. 32.50% of the ordinary income distributed by the Fund, for the year ended March 31, 2007, qualifies for the corporate dividends received deduction. For non-corporate shareholders 72.60%, 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 April 1, 2006 to March 31, 2007 may represent qualified dividend income.

After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements. In addition, the Board, including the Independent Trustees, considers matters bearing on the Agreements at most of its other meetings throughout the year and meets regularly with the heads of each investment area within Columbia. Through the Board's Investment Oversight Committees, Trustees also meet with selected fund portfolio managers at various times throughout the year. The Trustees receive and review all materials that they, their legal counsel or Columbia, the funds' investment adviser, believe to be reasonably necessary for the Trustees to evaluate the Agreements and determine whether to approve the continuation of the Agreements. Those materials generally include, among other items, (i) information on the investment performance of each fund relative to the performance of peer groups of mutual funds and the fund's performance benchmarks, (ii) information on each fund's advisory fees and other expenses, including information comparing the fund's expenses to those of peer groups of mutual funds and information about any applicable expense caps and fee "breakpoints," (iii) information about the profitability of the Agreements to Columbia, including potential "fall-out" or ancillary benefits that Columbia and its affiliates may receive as a result of their relationships with the funds and (iv) information obtained through Columbia's response to a questionnaire prepared at the request of the Trustees by counsel to the funds and independent legal counsel to the Independent Trustees. The Trustees also consider other information such as (v) Columbia's financial results and financial condition, (vi) each fund's investment objective and strategies and the size, education and experience of Columbia's investment staffs and their use of technology, external research and trading cost measurement tools, (vii) the allocation of the funds' brokerage, if any, and the use of "soft" commission dollars to pay for research products and services, (viii) Columbia's resources devoted to, and its record of compliance with, the funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (ix) Columbia's response to various legal and regulatory proceedings since 2003 and (x) the economic outlook generally and for the mutual fund industry in particular. In addition, the Advisory Fees and Expenses Committee confers with the funds' independent fee consultant and reviews materials relating to the funds' relationships with Columbia provided by the independent fee consultant. Throughout the process, the Trustees have the opportunity to ask questions of and request additional materials from Columbia and to consult with independent legal counsel to the Independent Trustees and the independent fee consultant. The Board of Trustees most recently approved the continuation of the Agreements at its October, 2006 meeting, following meetings of the Advisory Fees and Expenses Committee held in August, September and October, 2006. In considering whether to approve the continuation of the Agreements, the Trustees, including the Independent Trustees, did not identify any single factor as determinative, and each weighed various factors as he or she deemed appropriate. The Trustees considered the following matters in connection with their approval of the continuation of the Agreements: The nature, extent and quality of the services provided to the funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by Columbia and its affiliates to the funds and the resources dedicated to the funds by Columbia and its affiliates. Among other things, the Trustees considered (i) Columbia's ability (including its personnel and other resources, compensation programs for personnel involved in fund management, reputation and other attributes) to attract and retain highly qualified research, advisory and supervisory investment professionals; (ii) the portfolio management services provided by those investment professionals; and (iii) the trade execution services provided on behalf of the funds. For each fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the continuation of the Agreements. 36 Investment performance of the funds and Columbia. The Trustees reviewed information about the performance of each fund over various time periods, including information prepared by an independent third party that compared the performance of each fund to the performance of peer groups of mutual funds and performance benchmarks. The Trustees also reviewed a description of the third party's methodology for identifying each fund's peer group for purposes of performance and expense comparisons. The Trustees also considered additional information that the Advisory Fees and Expenses Committee requested from Columbia relating to funds that presented relatively weaker performance and/or relatively higher expenses. In the case of each fund whose performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Trustees concluded that other factors relevant to performance were sufficient, in light of other considerations, to warrant continuation of the fund's Agreements. Those factors varied from fund to fund, but included one or more of the following: (i) that the fund's performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the fund's investment strategy and policies and that the fund was performing as expected, given these investment decisions, market conditions and the fund's investment strategy; (iii) that the fund's performance was competitive when compared to other relevant performance benchmarks or peer groups; (iv) that Columbia had taken or was taking steps designed to help improve the fund's investment performance, including, but not limited to, replacing portfolio managers or modifying investment strategies; and (v) that the fund was proposed to be reorganized into another fund, and that such reorganization would result in a reduction in fund expenses. The Trustees also considered Columbia's performance and reputation generally, the funds' performance as a fund family generally, and Columbia's historical responsiveness to Trustee concerns about performance and Columbia's willingness to take steps intended to improve performance. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of each fund and Columbia was sufficient, in light of other considerations, to warrant the continuation of the Agreement(s) pertaining to that fund. The costs of the services provided and profits realized by Columbia and its affiliates from their relationships with the funds. The Trustees considered the fees charged to the funds for advisory services as well as the total expense levels of the funds. That information included comparisons (provided by management and by an independent third party) of each fund's advisory fees and total expense levels to those of the fund's peer groups and information about the advisory fees charged by Columbia to comparable institutional accounts. In considering the fees charged to those accounts, the Trustees took into account, among other things, management's representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for Columbia, and the additional resources required to manage mutual funds effectively. In evaluating each fund's advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the fund. The Trustees considered existing advisory fee breakpoints, and Columbia's use of advisory fee waivers and expense caps, which benefited a number of the funds. The Trustees also noted management's stated justification for the fees charged to the funds, which included information about the investment performance of the funds and the services provided to the funds. The Trustees also considered the compensation directly or indirectly received by Columbia and its affiliates from their relationships with the funds. The Trustees reviewed information provided by management as to the profitability to Columbia and its affiliates of their relationships with each fund, and information about the allocation of expenses used to calculate profitability. When reviewing profitability, the Trustees also considered court cases in which adviser profitability was an issue in whole or in part, the performance of the relevant funds, the expense level of each fund, and whether Columbia had implemented breakpoints and/or expense caps with respect to the fund. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each fund, and the related profitability to Columbia and its affiliates of their relationships with the fund, supported the continuation of the Agreement(s) pertaining to that fund. 37 Economies of Scale. The Trustees considered the existence of any economies of scale in the provision by Columbia of services to each fund, to groups of related funds, and to Columbia's investment advisory clients as a whole and whether those economies were shared with the funds through breakpoints in the investment advisory fees or other means, such as expense waivers/reductions and additional investments by Columbia in investment, trading and compliance resources. The Trustees noted that many of the funds benefited from breakpoints, expense caps, or both. In considering those issues, the Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to Columbia and its affiliates of their relationships with the funds, as discussed above. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the funds supported the continuation of the Agreements. Other Factors. The Trustees also considered other factors, which included but were not limited to the following: .. the extent to which each fund had operated in accordance with its investment objective and investment restrictions, the nature and scope of the compliance programs of the funds and Columbia and the compliance-related resources that Columbia and its affiliates were providing to the funds; .. the nature, quality, cost and extent of administrative and shareholder services performed by Columbia and its affiliates, both under the Agreements and under separate agreements for the provision of transfer agency and administrative services; .. so-called "fall-out benefits" to Columbia and its affiliates, such as the engagement of its affiliates to provide distribution, brokerage and transfer agency services to the funds, and the benefits of research made available to Columbia by reason of brokerage commissions generated by the funds' securities transactions, as well as possible conflicts of interest associated with those fall-out and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor those possible conflicts of interest; and .. the draft report provided by the funds' independent fee consultant, which included information about and analysis of the funds' fees, expenses and performance. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel and the independent fee consultant, the Trustees, including the Independent Trustees, approved the continuance of each of the Agreements through October 31, 2007. 38 Summary of Management Fee Evaluation by Independent Fee Consultant Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between the Office of Attorney General of New York State and Columbia Management Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006 I. Overview Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors, Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates that CMA may manage or advise a Columbia Fund ("Fund" and together with all such funds or a group of such funds as the "Funds") only if the Independent Members of the Fund's Board of Trustees (such Independent Members of the Fund's Board together with the other members of the Fund's Board, referred to as the "Trustees") appoint a Senior Officer or retain an Independent Fee Consultant ("IFC") who is to manage the process by which proposed management fees are negotiated. The AOD further stipulates that the Senior Officer or IFC is to prepare a written annual evaluation of the fee negotiation process. On September 14, 2006, the Independent Members of the Funds' Boards retained me as IFC for the Funds. In this capacity, I have prepared the second annual written evaluation of the fee negotiation process. I am successor to the first IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed to the second annual written evaluation until his resignation as IFC in August 2006 to become Director of the Division of Market Regulation at the U.S. Securities and Exchange Commission./2/ A. Role of the Independent Fee Consultant The AOD charges the IFC with "managing the process by which proposed management fees...to be charged the Columbia Fund are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." In this role, the IFC does not replace the Trustees in negotiating management fees with CMA, and the IFC does not substitute his or her judgment for that of the Trustees about the reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a Columbia Fund only if the reasonableness of the proposed management fees is determined by the Board of Trustees...using...an annual independent written evaluation prepared by or under the direction of...the Independent Fee Consultant." B. Elements Involved in Managing the Fee Negotiation Process Managing the fee negotiation process has three elements. One involves reviewing the information provided by CMG to the Trustees for evaluating the proposed management fees and augmenting that information, as necessary, with additional information from CMG or other sources and with further analyses of the information and data. The second element involves reviewing the information and analysis relative to at least the following six factors set forth in the AOD: 1.The nature and quality of CMA's services, including the Fund's performance; 2.Management fees (including any components thereof) charged by other mutual fund companies for like services; 3.Possible economies of scale as the Fund grows larger; 4.Management fees (including any components thereof) charged to institutional and other clients of CMA for like services; 5.Costs to CMA and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; and 6.Profit margins of CMA and its affiliates from supplying such services. 1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds' transfer agent. Before the date of this report, CMA merged into an affiliated entity, Banc of America Capital Management, LLC, which was renamed Columbia Management Advisors, LLC and which carries on the business of CMA. CFD also has been renamed Columbia Management Distributors, Inc. 2I am an independent economic consultant. From August 2005 until August 2006, I provided support to Mr. Sirri as an independent consultant. From 1994 to 2004, I was Chief Economist at the Investment Company Institute. Earlier, I was Section Chief and Assistant Director at the Federal Reserve Board and Professor of Economics at Oklahoma State University. I have no material relationship with Bank of America or CMG, aside from serving as IFC, and I am aware of no material relationship with any of their affiliates. To assist me with the report, I engaged NERA Economic Consulting, an independent consulting firm that has had extensive experience in the mutual fund industry. I also have retained Willkie Farr & Gallagher LLP as counsel to advise me in connection with the report. 39 The final element involves providing the Trustees with a written evaluation of the above factors as they relate to the fee negotiation process. C. Organization of the Annual Evaluation The 2006 annual evaluation focuses on the six factors and contains a section for each factor except that CMA's costs and profits from managing the Funds have been combined into a single section. In each section, the discussion of the factor considers and analyzes the available data and other information as they bear upon the fee negotiation process. If appropriate, the discussion in the section may point out certain aspects of the proposed fees that may warrant particular attention from the Trustees. The discussion also may suggest other data, information, and approaches that the Trustees might consider incorporating into the fee negotiation process in future years. In addition to a discussion of the six factors, the report reviews the status of recommendations made in the 2005 IFC evaluation. The 2006 report also summarizes the findings with regard to the six factors and contains a summary of recommendations for possible enhancements to the process. II. Status of 2005 Recommendations The 2005 IFC evaluation contains recommendations aimed at enhancing the evaluation of proposed management fees by Trustees. The section summarizes those recommendations and includes my assessment of the response to the recommendations. 1. Recommendation: Trustees should consider requesting more analytical work from CMG in the preparation of future 15(c) materials. Status: CMG has provided additional analyses to the Trustees on economies of scale, a comparative analysis of institutional and retail management fees, management fee breakpoints, risk-adjusted performance, fee waivers and expense reimbursements, and CMG's costs and profitability. 2. Recommendation: Trustees may wish to consider whether CMG should continue expanding the use of Morningstar or other third party data to supplement CMG's fee and performance analysis that is now based primarily on Lipper reports. Status: CMG has used data from Morningstar Inc. to compare with data from Lipper Inc. ("Lipper") in performing the Trustees' screening procedures. 3. Recommendation: Trustees should consider whether...the fund-by-fund screen...should place comparable emphasis on both basis point and quintile information in their evaluation of the funds...Also, the Trustees should consider incorporating sequences of one year performance into a fund-by-fund screen. Status: CMG has not provided Trustees with results of the screening process using percentiles. CMG has provided Trustees with information on the changes in performance and expenses between 2005 and 2006 and data on one-year returns. 4. Recommendation: Given the volatility of fund performance, the Trustees may want to consider whether a better method exists than th[e] fee waiver process to deal with fund underperformance. Status: It is my understanding that the Trustees have determined to address fund underperformance not only through fee waivers and expense caps but also through discussions with CMG regarding the sources of underperformance. CMG has provided Trustees with an analysis of the relationship between breakpoints, expense reimbursements, and fee waivers. 5. Recommendation: [Seventy-one] percent of funds [have] yet to reach their first management fee breakpoint... Trustees may wish to consider whether the results of my ongoing economies-of-scale work affects the underlying economic assumptions reflected in the existing breakpoint schedules. Status: CMG has prepared a memo for the Trustees discussing its views on the nature and sharing of potential economies of scale. The memo discuses CMG's view that economies of scale arise at the complex level rather than the fund level. The memo also describes steps, including the introduction of breakpoints, taken to share economies of scale with shareholders. CMG's analysis, however, does not discuss specific sources of economies of scale and does not link breakpoints to economies of scale that might be realized as the Funds' assets increase. 40 6. Recommendation: Trustees should continue working with management to address issues of funds that demonstrate consistent or significant underperformance even if the fee levels for the funds are low. Status: Trustees monitor performance on an ongoing basis. III. Findings A. General 1. Based upon my examination of the available information and the six factors, I conclude that the Trustees have the relevant information necessary to evaluate the reasonableness of the proposed management fees for the Funds. CMG has provided the Trustees with relevant materials on the six factors through the 15(c) contract renewal process and in materials prepared for review at Board and Committee meetings. 2. In my view, the process by which the proposed management fees of the Funds have been negotiated in 2006 thus far has been, to the extent practicable, at arms' length and reasonable and consistent with the AOD. B. Nature and Quality of Services, Including Performance 3. The performance of the Funds has been relatively strong, especially that of fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance periods, over 60 percent of the funds have ranked in the top three performance quintiles. 4. The performance of the equity Funds overall, though less concentrated in the top two quintiles than the fixed income Funds, improved in 2006 relative to that in 2005. The fixed-income funds maintained the relatively high performance level of 2005 in 2006. 5. The Funds' overall performance adjusted for risk was significantly stronger than performance unadjusted for risk. Domestic and international equity funds, in particular, moved to higher relative performance rankings after adjusting for risk. 6. The procedure used to construct the performance universe in which each Fund's performance is ranked relative to comparable funds may bias a Fund's ranking upward within that universe. The bias occurs because the performance ranking procedure includes all share classes of multi-class funds in the universe and because the procedure ranks either no-load or A share classes of the Funds. No-load and A share classes generally have lower total expenses than B and C shares (owing to B and C shares having higher distribution/service fees) and thus, given all else, would outperform many of B and C share classes included in the universe. A preliminary analysis that adjusts for the bias results in a downward movement in the relative performance for the Funds but does not change the general finding that the Funds' performance has been strong relative to comparable funds. C. Management Fees Charged by Other Mutual Fund Companies 7. The Funds' management fees and total expenses are generally low relative to those of their peers. At least 56 percent of the Funds are in the first or second quintiles with the lowest fees and expenses and nearly three fourths or more in the first three quintiles. Equity Funds are more highly concentrated in the first three quintiles than fixed-income Funds. 8. The fee and expense rankings as whole are similar to those in 2005 in that the majority of funds are ranked in the top quintiles. Nonetheless, a number of individual funds experienced a change in ranking between 2005 and 2006. This fund-level instability may reflect sensitivity of rankings to the composition of the comparison groups, as the membership of the peer groups typically changed substantially between the two years. 9. The Liberty Money Market Fund VS appears to have a higher management fee structure than that of other Columbia money market funds of comparable asset size. 41 D. Trustees' Fee and Performance Evaluation Process 10. The Trustees' evaluation process identified 21 funds in 2006 for further review based upon their relative performance or expenses. Seventeen of these funds had been subject to review in 2004 or 2005. E. Potential Economies of Scale 11. CMG has prepared a memo for the Trustees containing its views on the sources and sharing of potential economies of scale. CMG views economies of scale as arising at the complex level and would regard estimates of scale economies for individual funds as unreliable. CMG has not, however, identified specific sources of economies of scale nor has it provided any estimates of the magnitude of any economies of scale. In the memo, CMG also describes measures taken by the Trustees and CMG that seek to share any potential economies of scale through breakpoints in management fee schedules, expense reimbursements, fee waivers, enhanced shareholder services, fund mergers, and operational consolidation. These measures, although of significant benefit to shareholders, have not been directly linked in the memo to the existence, sources, and magnitude of economies of scale. F. Management Fees Charged to Institutional Clients 12. CMG has provided Trustees with comparisons of mutual fund management fees and institutional fees based upon standardized fee schedules and upon actual fees. Based upon the information, institutional fees are generally lower than the Funds' management fees. This pattern is consistent with the economics of the two financial products. Data are not available, however, on actual institutional fees at other money managers. Thus, it is not possible to determine the extent to which differences between the Funds' management fees and institutional fees are consistent with those seen generally in the marketplace. G. Revenues, Expenses, and Profits 13. The financial statements and the methodology underlying their construction generally form a sufficient basis for Trustees to evaluate the expenses and profitability of the Funds. IV. Recommendations A. Performance 1. Trustees may wish to consider incorporating risk adjusted measures in their evaluation of performance. CMG has begun to prepare reports for the Trustees with risk adjustments, which could form the basis for formally including the measures in the 15(c) materials. To this end, Trustees may wish to have CMG prepare documents explaining risk adjustments and describing their advantages and disadvantages. 2. Trustees may wish to consider having CMG evaluate the sensitivity of performance rankings to the design of the universe. The preliminary analysis contained in the evaluation suggests that the method employed by Lipper, the source of performance rankings used by the Trustees, may bias performance rankings upward. B. Economies of Scale 3. Trustees may wish to consider having CMG extend its analysis of economies of scale by examining the sources of such economies, if any. Identification of the sources may enable the Trustees and CMG to gauge their magnitude. It also may enable the Trustees and CMG to build upon past work on standardized fee schedules so that the schedules themselves are consistent with any economies of scale and their sources. Finally, an extension of the analysis may enable the Trustees and CMG to develop a framework that coordinates the use of fee waivers and expense caps with the standard fee schedules and with any economies of scale and their sources. C. Institutional Fees 4. Trustees may wish to consider encouraging CMG to build further upon its expanded analysis of institutional fees by refining the matching of institutional accounts with mutual funds, by dating the establishment of each institutional account, and by incorporating other accounts, such as subadvisory relationships, trusts, offshore funds, and separately managed accounts into the analysis. 42 D. Profitability 5. Trustees may wish to consider requesting that CMG expand the reporting of revenues and expenses to include more line-item detail for management and administration, transfer agency, fund accounting, and distribution. 6. Trustees may wish to consider requesting that CMG provide a statement of its operations in the 15(c) materials. 7. Trustees may wish to consider the treatment of the revenue sharing with the Private Bank of Bank of America in their review of CMG's profitability. Respectfully submitted, John D. Rea 43 Appendix Sources of Information Used in the Evaluation The following list generally describes the sources and types of information that were used in preparing this report. 1. Performance, management fees, and expense ratios for the Funds and comparable funds from other fund complexes from Lipper and CMG. The sources of this information were CMG and Lipper; 2. CMG's expenses and profitability obtained directly from CMG; 3. Information on CMG's organizational structure; 4. Profitability of publicly traded asset managers from Lipper; 5. Interviews with CMG staff, including members of senior management, legal staff, heads of affiliates, portfolio managers, and financial personnel; 6. Documents prepared by CMG for Section 15(c) contract renewals in 2005 and 2006; 7. Academic research papers, industry publications, professional materials on mutual fund operations and profitability, and SEC releases and studies of mutual fund expenses 8. Interviews with and documents prepared by Ernst & Young LLP in its review of the Private Bank Revenue Sharing Agreement; 9. Discussions with Trustees and attendance at Board and committee meetings during which matters pertaining to the evaluation were considered. In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data management and analysis. NERA has extensive experience in the mutual fund industry that provides unique insights and special knowledge pertaining to my independent analysis of fees, performance, and profitability. I have also retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher LLP as outside counsel to advise me in connection with my evaluation. Finally, meetings and discussions with CMG staff were informative. My participation in Board and committee meetings in which Trustees and CMG management discussed issues relating to management contracts were of great benefit to the preparation of the evaluation. 44 Important Information About This Report Columbia World Equity Fund Transfer Agent Columbia Management Services, Inc.

Wilson President, Columbia Funds Dear Shareholder: Investing is a long-term process and we are pleased that you have chosen to include the Columbia family of funds in your overall financial plan. Your financial advisor can help you establish an appropriate investment portfolio and periodically review that portfolio. A well balanced portfolio is one of the keys to successful long-term investing. Your portfolio should be diversified across different asset classes and market segments and your chosen asset allocation should be appropriate for your investment goals, risk tolerance and time horizons. However, creating an investment strategy is not a one-step process. From time to time, you'll need to re-evaluate your strategy to determine whether your investment needs have changed. Most experts recommend giving your portfolio a "check-up" every year. As you begin your portfolio check-up, consider whether you have experienced any major life events since the last time you assessed your portfolio. You may need to tweak your strategy if you have: .. Gotten married or divorced .. Added a child to your family .. Made a significant change in employment .. Entered or moved significantly closer to retirement .. Experienced a serious illness or death in the family .. Taken on or paid off substantial debt It's important to remember that over time, performance in different market segments will fluctuate. These shifts can cause your portfolio balance to drift away from your chosen asset allocation. A periodic portfolio check-up can help make sure your portfolio stays on track. Remember that asset allocation does not ensure a profit or guarantee against loss. You'll also want to analyze the individual investments in your portfolio. Of course, performance should be a key factor in your analysis, but it's not the only factor to consider. Make sure the investments in your portfolio line up with your overall objectives and risk tolerance. Be aware of changes in portfolio management and pay special attention to any funds that have made significant shifts in their investment strategy. We hope this information will help you, in working with your financial advisor, to stay on track to reach your investment goals. Thank you for your business and for your continued confidence in Columbia Funds. Sincerely, /s/ Christopher L. Wilson Christopher L. Wilson President, Columbia Funds Economic Update - Columbia Income Fund Summary For the 12-month period ended March 31, 2007 . Investment-grade bonds rebounded as yields declined, lifting the Lehman Brothers U.S. Aggregate Bond Index to a respectable return. High-yield bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led the US fixed-income markets. Lehman Merrill Lynch Index Index [GRAPHIC] [GRAPHIC] 6.59% 11.45% . The broad US stock market, as measured by the S&P 500 Index, returned 11.83%. Stock markets outside the United States were even stronger, as measured by the MSCI EAFE Index. S&P Index MSCI Index [GRAPHIC] [GRAPHIC] 11.83% 20.20% The Lehman Brothers U.S. 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, and 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 U.S. High Yield, Cash Pay Index tracks the performance of non-investment-grade corporate bonds. The S&P 500 Index tracks the performance of 500 widely held, large-capitalization US stocks. The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. 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. US economic growth advanced at a modest pace during the 12-month period that began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on the economy throughout the period, with few signs that relief was imminent. Energy prices trended downward, but rose again late in the period, and core inflation moved higher. Yet, many economic indicators remained positive. Job growth, for example, was relatively strong, as the labor markets added an average of 164,000 new jobs each month over the period and the unemployment rate declined to 4.4%. Personal income rose and consumer spending continued to expand, albeit at a slower pace as the period wore on. Against this backdrop, economic growth averaged around 2.2% for the 12-month period. Between April and June 2006, the Federal Reserve Board (the Fed) raised a key short-term interest rate, the federal funds rate, twice -- to 5.25%. But after its June meeting, the Fed turned cautious in the face of slower economic growth and held the federal funds rate steady. Investors reacted favorably to the prospect of stable or lower interest rates and fueled a rally that moved stock prices higher and gave a boost to the bond market as well. Bonds bounced back Although bond yields moved higher early in the period, most segments of the US bond market delivered respectable returns, as prices rose and yields declined in reaction to the Fed's mid-year decision to put further short-term rate increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether for the bond market, ended the 12-month period at 4.63% -- somewhat lower than where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond Index returned 6.59%. High-yield bonds led the US fixed-income markets, reflecting investor confidence about the overall resilience of the economy despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay Index returned 11.45%. Despite late set-back, stocks moved solidly higher Stock prices rose at an above-average pace during the 12-month period covered by this report. The S&P 500 Index, a broad measure of common stock performance, rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap stocks, as measured by their respective Russell indices. Foreign stock markets were even stronger than the US market. The MSCI EAFE Index, which tracks stock market performance in industrialized countries outside the United States, returned 20.20%, despite a volatile stretch late in the period when the US and many foreign stock markets retreated in response to a sharp decline in the Chinese market and other market-specific factors. /1/10-year Treasury not used solely as a benchmark for long-term interest rates.

The Lehman Brothers Intermediate Government/Credit Bond Index tracks the performance of intermediate term US government and corporate bonds. The Lehman Brothers Intermediate Credit Bond Index is the intermediate component of the U.S. Credit Index. The U.S. Credit Index includes publicly issued US corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements. 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. Performance results reflect any waivers or reimbursements of fund expenses by the investment advisor and/or any of its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. All results shown assume reinvestment of distributions. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. 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 requirements may vary. Please see the fund's prospectus for details. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The returns of Class A shares include returns of the fund's Class Z shares (the oldest existing fund share class) for periods prior to the inception of Class A shares. The returns of Class B and Class C shares include returns of the fund's Class A shares for periods prior to the inception of Class B and Class C shares, respectively. The returns of Class B and Class C shares also include returns of the fund's Class Z shares for periods prior to the inception of Class A shares. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A, Class B or Class C shares or between Class A shares and Class B or Class C shares. If differences in expenses had been reflected, the returns shown for Class A, Class B and Class C shares for periods prior to the inception of Class A, Class B and Class C shares, respectively, would have been lower. Class A shares were initially offered on July 31, 2000, Class B and Class C shares were initially offered on July 15, 2002, and Class Z shares were initially offered on March 5, 1986. 2 Understanding Your Expenses - Columbia Income Fund 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. 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 fees, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand the ongoing costs of investing in the fund and to compare these costs with the ongoing 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 $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated based on the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing cost of investing in a fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. 10/01/06 - 03/31/07 Account value at the Account value at the Expenses paid Fund's annualized beginning of the period ($) end of the period ($) during the period ($) expense ratio (%) - ------------------------------------------------------------------------------------------------- Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,028.12 1,020.19 4.80 4.78 0.95 Class B 1,000.00 1,000.00 1,024.28 1,016.45 8.58 8.55 1.70 Class C 1,000.00 1,000.00 1,025.08 1,017.20 7.83 7.80 1.55 Class Z 1,000.00 1,000.00 1,029.42 1,021.44 3.54 3.53 0.70 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 investment advisor and/or any of its affiliates not waived or reimbursed a portion of expenses, account value at the end of the period would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical examples provided may not help you determine the relative total costs of owning shares of different funds. If these transaction costs were included, your costs would have been higher. 3 Portfolio Managers' Report - Columbia Income Fund Performance data quoted represents past performance and current performance may be lower or higher.

The fund's return was lower than the returns of its benchmarks, the Lehman Brothers Intermediate Government/Credit Bond Index and the Lehman Brothers Intermediate Credit Bond Index, which returned 6.14% and 6.82%, respectively, for the same period./1/ The fund's return was also lower than the average return of its peer group the Lipper Corporate Debt Funds BBB Rated Classification, which was 6.88% for the 12-month period./2/ Allocation decisions within the financial sector accounted for the performance shortfall. The past 12 months were a fairly stable period for the fixed-income markets. Three months into the period, the Federal Reserve Open Market Committee (the Fed) suspended its two-year-long string of short-term interest rate hikes, and stayed on the sidelines for the remainder of the period. Meanwhile, inflation remained moderate enough to bring long-term rates down slightly. The net result was a healthy bond market. While long-term bonds tended to outperform issues with shorter maturities, solid gains were posted at all points of the maturity spectrum. Steady economic growth favored corporate bonds The national economy managed to stay in a sweet spot characterized by strong growth and the absence of undue inflationary pressures. The economy's steady growth created a favorable environment for corporate bonds, consistent with a general trend in which fixed-income investors were rewarded for assuming credit risk. In particular, high-yield bonds were the top performing bond market sector during the period. Our decision to overweight the high-yield sector enabled the fund to maintain its competitiveness with other intermediate bond funds. However, this reward for risk-taking did not extend to the mortgage market. Toward the end of the period, a surge in foreclosures experienced by subprime lenders resulted in significant losses for low-quality mortgage pools. While the fund's exposure to subprime securities was limited, many of its mortgage holdings lost ground as investors worried that problems could spill over to other areas of the market. The fund's sector decisions experienced mixed results during the period. Positions in the financial sector helped performance for the first six months, then hampered performance in the second half, above and beyond subprime concerns. A decision to underweight the insurance sector also hampered performance as major carriers delivered above-average performance after a mild hurricane year. We plan to add to the fund's insurance holdings because of the balance sheet improvements created by the limited payouts of the past year and limited subprime exposure. In addition, we believe insurers appear to be less likely than other financial companies to be candidates for a private equity transaction. /1/The Lehman Brothers Intermediate Government/Credit Bond Index tracks the performance of intermediate term US government and corporate bonds. The Lehman Brothers Intermediate Credit Bond Index is the intermediate component of the U.S. Credit Index. The U.S. Credit Index includes publicly issued US corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements. Indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. It is not possible to invest directly in an index. /2/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 Portfolio Managers' Report (continued) - Columbia Income Fund Looking ahead We plan to take a more neutral view of the high-yield market now that low quality issues offer historically low yield advantages versus investment-grade credits. The fund is currently overweight in AAA and BBB-rated bonds, whose prospects we believe remain attractive given our constructive outlook for the economy as a whole. While the bond market still faces an elevated risk of shareholder-friendly leveraged transactions, we believe such risks are to a large degree priced into today's yield levels.

Summary .. For the 12-month period that ended March 31, 2007, the fund's Class A shares returned 6.04 % without sales charge. .. The fund's return was lower than the return of its benchmark and the average return of its peer group. .. The fund had more exposure than the indices to high-yield bonds, the best-performing sector of the fixed-income market, which benefited performance. However, the composition of holdings in the financial sector hurt relative performance in the second half of the period. Portfolio Management Kevin L.

The outlook for this fund may differ from that presented for other Columbia Funds. Performance for different classes of shares will vary based on differences in sales charges and fees associated with each class. For standardized performance, please refer to the Performance Information page. Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yield and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa. Investing in high-yield securities (commonly known as "junk" bonds) offers the potential for high current income and attractive total return but involves certain risks. Changes in economic conditions or other circumstances may adversely affect a junk bond issuer's ability to make principal and interest payments. Rising interest rates tend to lower the value of all bonds. High-yield bonds issued by foreign entities have greater potential risks, including less regulation, currency fluctuations, economic instability and political developments. 6 Financial Statements - Columbia Income Fund March 31, 2007 A guide to understanding your fund's financial statements ------------------------------------- Investment Portfolio The investment portfolio details all of the fund's holdings and their values as of the last day of the reporting period.

See Accompanying Notes to Financial Statements. 37 Notes to Financial Statements - Columbia Income Fund March 31, 2007 Note 1. Organization Columbia Income Fund (the "Fund"), a series of Columbia Funds Series Trust I (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 its total return by investing for a high level of current income and, to a lesser extent, 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 eight 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 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. Forward currency exchange contracts are valued at the prevailing forward exchange rate of the underlying currencies. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded. Foreign securities are generally valued at the last sale price on the foreign exchange or market on which they trade. If any foreign share prices are not readily available as a result of limited share activity, the securities are valued at the last sale price of the local shares in the principal market in which such securities are normally traded. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. Events affecting the values of such foreign securities and such exchange rates may occur between the times at which they are determined and the close of the customary trading session of the NYSE, which would not be reflected in the computation of the Fund's net asset value. If 38 Columbia Income Fund March 31, 2007 events materially affecting the values of such foreign securities occur and it is determined that market quotations are not reliable, then these foreign securities will be valued at their fair value using procedures approved by the Board of Trustees. 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 "fair value", such value is likely to be different from the last quoted market price for the security. In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is evaluating the impact the application of SFAS 157 will have on the Fund's financial statement disclosures. 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. Forward Foreign Currency Exchange Contracts Forward foreign currency exchange contracts are agreements to exchange one currency for another at a future date at a specified price. These contracts are used to minimize the exposure to foreign exchange rate fluctuations during the period between trade and settlement date. The Fund may utilize forward foreign currency exchange contracts in connection with the settlement of purchases and sales of securities. The Fund may also enter into these contracts to hedge certain other foreign currency denominated assets. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell are used to hedge the Fund's investments against currency fluctuations. Forward currency contracts are valued daily at the current exchange rate of the underlying currency, resulting in unrealized gains (losses) which become realized at the time the foreign currency contracts are closed or mature. Realized and unrealized gains (losses) arising from such transactions are included in net realized and unrealized gains (losses) on foreign currency transactions. The use of forward currency contracts does not eliminate fluctuations in the prices of the Fund's portfolio securities. Although the maximum potential loss from such contracts is the aggregate face value in U.S. dollars at the time the contract was opened, exposure is typically limited to the change in value of the contract (in U.S. dollars) over the period it remains open. The Fund could also be exposed to risk if the counterparties of the contracts are unable to fulfill the terms of the contracts. The counterparty risk exposure is, therefore, closely monitored and contracts are only executed with high credit quality financial institutions. Repurchase Agreements The Fund may engage in repurchase agreement transactions with institutions that Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy. The Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Columbia is responsible for determining that 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. 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 holds until settlement date, in a segregated account, cash or liquid securities in an amount equal to the delayed delivery commitment. Mortgage Dollar Roll Transactions The Fund may enter into mortgage "dollar rolls" in which the Fund sells securities for delivery in the current month and 39 Columbia Income Fund March 31, 2007 simultaneously contracts with the same counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date not exceeding 120 days. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase (often referred to as the "drop") or fee income plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. Unless such benefits exceed the income, capital appreciation and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared with what such performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund will hold and maintain in a segregated account until the settlement date, cash or liquid securities in an amount equal to the forward purchase price. The Fund's policy is to record the components of mortgage dollar rolls using "to be announced" mortgage-backed securities ("TBA Dollar Rolls"). For financial reporting and tax purposes, the Fund treats mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing. Mortgage dollar rolls involve certain risks. If the broker-dealer to whom the Fund sells the security becomes insolvent, the Fund's right to purchase or repurchase the mortgage-related securities may be restricted and the instrument which the Fund is required to repurchase may be worth less than an instrument which the Fund originally held. Successful use of mortgage dollar rolls may depend upon the investment advisor's ability to predict correctly interest rates and mortgage prepayments. For these reasons, there is no assurance that mortgage dollar rolls can be successfully employed. Futures Contracts The Fund may invest in futures contracts to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or derived from, the value of the underlying security, index, or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The fund typically uses derivatives in an effort to achieve more efficiently economic exposure similar to those it could have achieved through the purchase and sale of fixed income securities. 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 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. Income Recognition Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Fee income attributable to a mortgage dollar roll transaction is accrued over the term of the transaction. 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 in the Statement of Operations. 40 Columbia Income Fund March 31, 2007 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 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 the ex-date. Dividends from net investment income are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Indemnification In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Fund's organizational documents and by contract, the trustees and officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these representations, warranties and indemnities to be minimal. 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 March 31, 2007, permanent book and tax basis differences resulting primarily from differing treatments for in-kind redemptions, discount accretion/premium amortization on debt securities and paydown gain/loss reclasses were identified and reclassified among the components of the Fund's net assets as follows: Overdistributed Accumulated Net Investment Net Realized Income Loss Paid-In Capital $1,550,220 $(1,430,526) $(119,694) 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 March 31, 2007 and March 31, 2006 was as follows: March 31, 2007 March 31, 2006 Distributions paid from: Ordinary Income* $30,313,269 $30,696,439 *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of March 31, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Net Ordinary Long-Term Unrealized Income Capital Gains Appreciation* $1,163,993 $-- $2,011,940 *The differences between book-basis and tax-basis net unrealized appreciation are primarily due to differing treatments of capital loss carryforwards, futures contracts, forward currency contracts, distribution reclassifications and discount accretion/premium amortization on debt securities and deferral of losses from wash sales. Unrealized appreciation and depreciation at March 31, 2007, based on cost of investments for federal income tax purposes were: Unrealized appreciation $ 8,750,055 Unrealized depreciation (6,738,115) Net unrealized appreciation $ 2,011,940 41 Columbia Income Fund March 31, 2007 The following capital loss carryforwards, determined as of March 31, 2007, 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 2008 $ 7,932,135 2009 8,620,038 2010 1,393,345 2011 2,985,140 2014 3,731,648 2015 6,709,359 Total $31,371,665 Of the capital loss carryforwards attributable to the Fund, $10,086,973 ($4,838,296 will expire March 31, 2008, $3,855,332 will expire March 31, 2009 and $1,393,345 will expire March 31, 2010) was obtained in a merger with Liberty Income Fund. 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 March 31, 2007, capital losses of $292,784 attributed to security transactions were deferred to April 1, 2007. 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 No. 109 (the "Interpretation"). This Interpretation is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006 and is to be applied to open 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 is evaluating 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, an indirect, wholly-owned subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to the Fund. 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 0.420% $500 million to $1 billion 0.375% $1 billion to $1.5 billion 0.370% $1.5 billion to $3 billion 0.340% $3 billion to $6 billion 0.330% Over $6 billion 0.320% For the year ended March 31, 2007, the Fund's effective investment advisory fee rate was 0.42% 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 $1 billion 0.125% Over $1 billion 0.100% For the year ended March 31, 2007, the Fund's effective administration fee rate was 0.13% of the Fund's average daily net assets. Pricing and Bookkeeping Fees Effective December 15, 2006, the Fund entered into a Financial Reporting Services Agreement with State Street Bank & Trust Company ("State Street") and Columbia (the "Financial Reporting Services Agreement") pursuant to which State Street provides financial reporting services to the Fund. Also effective December 15, 2006, the Fund entered into an Accounting Services Agreement with State Street and 42 Columbia Income Fund March 31, 2007 Columbia (collectively with the Financial Reporting Services Agreement, the "State Street Agreements") pursuant to which State Street provides accounting services to the Fund. Under the State Street Agreements, the Fund pays State Street an annual fee of $38,000 paid monthly plus an additional monthly fee based on an annualized percentage rate of average daily net assets of the Fund for the month. Under the State Street Agreements, the combined fee payable to State Street by the Fund will not exceed $140,000 annually. The Fund also reimburses State Street for certain out-of-pocket expenses. Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping Oversight and Services Agreement (the "Services Agreement") with Columbia. Under the Services Agreement, Columbia provides services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides oversight of the accounting and financial reporting services provided by State Street. Under the Services Agreement, the Fund reimburses Columbia for out-of-pocket expenses and direct internal costs relating to accounting oversight and for services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002. Prior to December 15, 2006, Columbia was responsible for providing pricing and bookkeeping services to the Fund under a pricing and bookkeeping agreement. Under its pricing and bookkeeping agreement with the Fund, Columbia was entitled to receive an annual fee at the same fee structure described above under the State Street Agreements. Under separate agreements between Columbia and State Street, Columbia delegated certain functions to State Street. As a result of the delegation, the total fees payable under the pricing and bookkeeping agreement (other than certain reimbursements paid to Columbia and discussed below) were paid to State Street. The Fund also reimbursed 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 March 31, 2007, the Fund's effective pricing and bookkeeping fee rate, 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 and 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 reimbursement of certain 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 other parties (including affiliates of BOA) for services to those accounts. The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursements for such fees from the Fund. 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. For the year ended March 31, 2007, the Fund's effective transfer agent fee rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was 0.07% of the Fund's average daily net assets. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. For the year ended March 31, 2007, the Distributor has retained net underwriting discounts of $17,869 on sales of the Fund's Class A shares and net CDSC fees of $146, $42,193 and $4,239 on Class A, Class B and Class C share redemptions, respectively. The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Fund. The Plan also requires the payment of a monthly distribution fee to the Distributor at the annual rate of 0.75% 43 Columbia Income Fund March 31, 2007 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 of Class C average daily net assets. These waivers may be modified or terminated by the Distributor at any time. 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 in the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. Fees Paid to Officers and Trustees All officers of the Fund are employees of Columbia or its affiliates and, with the exception of the Fund's Chief Compliance Officer, receive no compensation from the Fund. The Board of Trustees has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund, along with other affiliated funds, pays its pro-rata share of the expenses associated with the Chief Compliance Officer. The Fund's expenses for the Chief Compliance Officer will not exceed $15,000 per year. The Fund's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Fund's assets. Other Columbia provides certain services to the Fund related to the requirements of the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund paid $2,875 to Columbia for such services. This amount is included in "Other expenses" in the Statement of Operations. Note 5. Portfolio Information For the year ended March 31, 2007, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $954,353,413 and $770,695,484, respectively, of which $271,381,164 and $306,200,420, respectively, were U.S. Government securities. Note 6. Line of Credit The Trust and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured line of credit, both provided by State Street. Borrowings are available for temporary or emergency purposes. Interest on the committed line of credit is charged to each participating fund based on the fund's 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 committed line of credit. Interest on the uncommitted line of credit is charged to each participating fund based on the fund's borrowings at a variable rate per annum equal to the Federal Funds Rate plus a spread, as determined and quoted by State Street at the time of the request for a loan. A one-time structuring fee of $30,000 is also accrued and apportioned to each fund participating in the uncommitted line of credit based on the average net assets of the participating funds. In addition, if the uncommitted line of credit is extended for an additional period, an annual administration fee of $15,000 will be charged and apportioned among the participating fund. The commitment fee and structuring fee are included in "Other expenses" in the Statement of Operations. For the year ended March 31, 2007, the Fund did not borrow under this arrangement. Note 7. Shares of Beneficial Interest As of March 31, 2007, the Fund had one shareholder that held 41.8% of the shares outstanding. These shares were beneficially owned by participant accounts over which BOA and/or its affiliates had either sole or joint investment discretion. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. As of March 31, 2007, the Fund had one shareholder that held 8.6% of the shares outstanding. These shares were beneficially owned by participant accounts over which BOA 44 Columbia Income Fund March 31, 2007 and/or its affiliates did not have investment discretion. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. Note 8. Securities lending The Fund commenced a securities lending program in August 2006 and may lend its securities to certain approved brokers, dealers and other financial institutions. Each loan is collateralized by cash, in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The collateral received is invested and the income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, is paid to the Fund. Generally, in the event of borrower default, the Fund has the right to use the collateral to offset any losses incurred. In the event the Fund is delayed or prevented from exercising its right to dispose of the collateral, there may be a potential loss to the Fund. The Fund bears the risk of loss with respect to the investment of collateral. Note 9. Other During the year ended March 31, 2007, the Fund had a realized investment loss in the amount of $3,209 due to a trading error. Columbia voluntarily reimbursed the Fund for the loss. Note 10. Disclosure of Significant Risks and Contingencies 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. Sector Focus Companies that are in different but closely related industries are sometimes described as being in the same sector. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector. During such times, the Fund will have greater exposure to the economic and market events affecting such sector than if it were more broadly invested across multiple sectors. 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") on matters relating to mutual fund trading. The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". 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 that was 45 Columbia Income Fund March 31, 2007 developed by an independent distribution consultant and approved by the SEC on April 6, 2007. 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 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 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. 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 were not dismissed. On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that certain conduct, including market timing, entitled Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was removed to federal court in Massachusetts and the federal Judicial Panel 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 settlement is subject to court approval. In 2004, the Columbia Funds' adviser and distributor and certain affiliated entities and individuals 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. Certain Columbia Funds were named as nominal defendants. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment in favor of the defendants. The plaintiffs appealed to the United States Court of Appeals for the First Circuit on December 30, 2005. A stipulation and settlement agreement dated January 19, 2007 was filed in the First Circuit on February 14, 2007, with a joint stipulation of dismissal and motion for remand to obtain district court approval of the settlement. That joint motion was granted and the appeal was dismissed. On March 6, 2007, the case was remanded to the District Court. On May 11, 2007, the District Court entered a preliminary approval order which granted preliminary approval of the settlement. A final settlement hearing, at which the District Court will determine whether the proposed settlement should be finally approved and the action dismissed on the merits with prejudice, is scheduled for September 18, 2007. The terms of the settlement, if finally approved, will require payments by the funds' adviser and/or its affiliates, including payment of plaintiffs' attorneys' fees and notice to class members. In the event that the settlement is not finally approved, the plaintiffs may elect to go forward with their appeal and no opinion is expressed regarding the likely outcome or financial impact of such an appeal on any fund. 46 Report of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia Income 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 Income Fund (the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2007 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for periods prior to July 1, 2003 were audited by another independent registered public accounting firm whose report dated August 19, 2003 expressed an unqualified opinion on those statements.

After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements. In addition, the Board, including the Independent Trustees, considers matters bearing on the Agreements at most of its other meetings throughout the year and meets regularly with the heads of each investment area within Columbia. Through the Board's Investment Oversight Committees, Trustees also meet with selected fund portfolio managers at various times throughout the year. The Trustees receive and review all materials that they, their legal counsel or Columbia, the funds' investment adviser, believe to be reasonably necessary for the Trustees to evaluate the Agreements and determine whether to approve the continuation of the Agreements. Those materials generally include, among other items, (i) information on the investment performance of each fund relative to the performance of peer groups of mutual funds and the fund's performance benchmarks, (ii) information on each fund's advisory fees and other expenses, including information comparing the fund's expenses to those of peer groups of mutual funds and information about any applicable expense caps and fee "breakpoints," (iii) information about the profitability of the Agreements to Columbia, including potential "fall-out" or ancillary benefits that Columbia and its affiliates may receive as a result of their relationships with the funds and (iv) information obtained through Columbia's response to a questionnaire prepared at the request of the Trustees by counsel to the funds and independent legal counsel to the Independent Trustees. The Trustees also consider other information such as (v) Columbia's financial results and financial condition, (vi) each fund's investment objective and strategies and the size, education and experience of Columbia's investment staffs and their use of technology, external research and trading cost measurement tools, (vii) the allocation of the funds' brokerage, if any, and the use of "soft" commission dollars to pay for research products and services, (viii) Columbia's resources devoted to, and its record of compliance with, the funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (ix) Columbia's response to various legal and regulatory proceedings since 2003 and (x) the economic outlook generally and for the mutual fund industry in particular. In addition, the Advisory Fees and Expenses Committee confers with the funds' independent fee consultant and reviews materials relating to the funds' relationships with Columbia provided by the independent fee consultant. Throughout the process, the Trustees have the opportunity to ask questions of and request additional materials from Columbia and to consult with independent legal counsel to the Independent Trustees and the independent fee consultant. The Board of Trustees most recently approved the continuation of the Agreements at its October, 2006 meeting, following meetings of the Advisory Fees and Expenses Committee held in August, September and October, 2006. In considering whether to approve the continuation of the Agreements, the Trustees, including the Independent Trustees, did not identify any single factor as determinative, and each weighed various factors as he or she deemed appropriate. The Trustees considered the following matters in connection with their approval of the continuation of the Agreements: The nature, extent and quality of the services provided to the funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by Columbia and its affiliates to the funds and the resources dedicated to the funds by Columbia and its affiliates. Among other things, the Trustees considered (i) Columbia's ability (including its personnel and other resources, compensation programs for personnel involved in fund management, reputation and other attributes) to attract and retain highly qualified research, advisory and supervisory investment professionals; (ii) the portfolio management services provided by those investment professionals; and (iii) the trade execution services provided on behalf of the funds. For each fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services. After reviewing those and related factors, the Trustees concluded, within the context of their 52 overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the continuation of the Agreements. Investment performance of the funds and Columbia. The Trustees reviewed information about the performance of each fund over various time periods, including information prepared by an independent third party that compared the performance of each fund to the performance of peer groups of mutual funds and performance benchmarks. The Trustees also reviewed a description of the third party's methodology for identifying each fund's peer group for purposes of performance and expense comparisons. The Trustees also considered additional information that the Advisory Fees and Expenses Committee requested from Columbia relating to funds that presented relatively weaker performance and/or relatively higher expenses. In the case of each fund whose performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Trustees concluded that other factors relevant to performance were sufficient, in light of other considerations, to warrant continuation of the fund's Agreements. Those factors varied from fund to fund, but included one or more of the following: (i) that the fund's performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the fund's investment strategy and policies and that the fund was performing as expected, given these investment decisions, market conditions and the fund's investment strategy; (iii) that the fund's performance was competitive when compared to other relevant performance benchmarks or peer groups; (iv) that Columbia had taken or was taking steps designed to help improve the fund's investment performance, including, but not limited to, replacing portfolio managers or modifying investment strategies; and (v) that the fund was proposed to be reorganized into another fund, and that such reorganization would result in a reduction in fund expenses. The Trustees also considered Columbia's performance and reputation generally, the funds' performance as a fund family generally, and Columbia's historical responsiveness to Trustee concerns about performance and Columbia's willingness to take steps intended to improve performance. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of each fund and Columbia was sufficient, in light of other considerations, to warrant the continuation of the Agreement(s) pertaining to that fund. The costs of the services provided and profits realized by Columbia and its affiliates from their relationships with the funds. The Trustees considered the fees charged to the funds for advisory services as well as the total expense levels of the funds. That information included comparisons (provided by management and by an independent third party) of each fund's advisory fees and total expense levels to those of the fund's peer groups and information about the advisory fees charged by Columbia to comparable institutional accounts. In considering the fees charged to those accounts, the Trustees took into account, among other things, management's representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for Columbia, and the additional resources required to manage mutual funds effectively. In evaluating each fund's advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the fund. The Trustees considered existing advisory fee breakpoints, and Columbia's use of advisory fee waivers and expense caps, which benefited a number of the funds. The Trustees also noted management's stated justification for the fees charged to the funds, which included information about the investment performance of the funds and the services provided to the funds. The Trustees also considered the compensation directly or indirectly received by Columbia and its affiliates from their relationships with the funds. The Trustees reviewed information provided by management as to the profitability to Columbia and its affiliates of their relationships with each fund, and information about the allocation of expenses used to calculate profitability. When reviewing profitability, the Trustees also considered court cases in which adviser profitability was an issue in whole or in part, the performance of the relevant funds, the expense level of each fund, and whether Columbia had implemented breakpoints and/or expense caps with respect to the fund. 53 After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each fund, and the related profitability to Columbia and its affiliates of their relationships with the fund, supported the continuation of the Agreement(s) pertaining to that fund. Economies of Scale. The Trustees considered the existence of any economies of scale in the provision by Columbia of services to each fund, to groups of related funds, and to Columbia's investment advisory clients as a whole and whether those economies were shared with the funds through breakpoints in the investment advisory fees or other means, such as expense waivers/reductions and additional investments by Columbia in investment, trading and compliance resources. The Trustees noted that many of the funds benefited from breakpoints, expense caps, or both. In considering those issues, the Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to Columbia and its affiliates of their relationships with the funds, as discussed above. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the funds supported the continuation of the Agreements. Other Factors. The Trustees also considered other factors, which included but were not limited to the following: .. the extent to which each fund had operated in accordance with its investment objective and investment restrictions, the nature and scope of the compliance programs of the funds and Columbia and the compliance-related resources that Columbia and its affiliates were providing to the funds; .. the nature, quality, cost and extent of administrative and shareholder services performed by Columbia and its affiliates, both under the Agreements and under separate agreements for the provision of transfer agency and administrative services; .. so-called "fall-out benefits" to Columbia and its affiliates, such as the engagement of its affiliates to provide distribution, brokerage and transfer agency services to the funds, and the benefits of research made available to Columbia by reason of brokerage commissions generated by the funds' securities transactions, as well as possible conflicts of interest associated with those fall-out and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor those possible conflicts of interest; and .. the draft report provided by the funds' independent fee consultant, which included information about and analysis of the funds' fees, expenses and performance. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel and the independent fee consultant, the Trustees, including the Independent Trustees, approved the continuance of each of the Agreements through October 31, 2007. 54 Summary of Management Fee Evaluation by Independent Fee Consultant Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between the Office of Attorney General of New York State and Columbia Management Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006 I. Overview Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors, Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates that CMA may manage or advise a Columbia Fund ("Fund" and together with all such funds or a group of such funds as the "Funds") only if the Independent Members of the Fund's Board of Trustees (such Independent Members of the Fund's Board together with the other members of the Fund's Board, referred to as the "Trustees") appoint a Senior Officer or retain an Independent Fee Consultant ("IFC") who is to manage the process by which proposed management fees are negotiated. The AOD further stipulates that the Senior Officer or IFC is to prepare a written annual evaluation of the fee negotiation process. On September 14, 2006, the Independent Members of the Funds' Boards retained me as IFC for the Funds. In this capacity, I have prepared the second annual written evaluation of the fee negotiation process. I am successor to the first IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed to the second annual written evaluation until his resignation as IFC in August 2006 to become Director of the Division of Market Regulation at the U.S. Securities and Exchange Commission./2/ A. Role of the Independent Fee Consultant The AOD charges the IFC with "managing the process by which proposed management fees...to be charged the Columbia Fund are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." In this role, the IFC does not replace the Trustees in negotiating management fees with CMA, and the IFC does not substitute his or her judgment for that of the Trustees about the reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a Columbia Fund only if the reasonableness of the proposed management fees is determined by the Board of Trustees...using...an annual independent written evaluation prepared by or under the direction of...the Independent Fee Consultant." B. Elements Involved in Managing the Fee Negotiation Process Managing the fee negotiation process has three elements. One involves reviewing the information provided by CMG to the Trustees for evaluating the proposed management fees and augmenting that information, as necessary, with additional information from CMG or other sources and with further analyses of the information and data. The second element involves reviewing the information and analysis relative to at least the following six factors set forth in the AOD: 1.The nature and quality of CMA's services, including the Fund's performance; 2.Management fees (including any components thereof) charged by other mutual fund companies for like services; 3.Possible economies of scale as the Fund grows larger; 4.Management fees (including any components thereof) charged to institutional and other clients of CMA for like services; 5.Costs to CMA and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; and 6.Profit margins of CMA and its affiliates from supplying such services. 1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds' transfer agent. Before the date of this report, CMA merged into an affiliated entity, Banc of America Capital Management, LLC, which was renamed Columbia Management Advisors, LLC and which carries on the business of CMA. CFD also has been renamed Columbia Management Distributors, Inc. 2I am an independent economic consultant. From August 2005 until August 2006, I provided support to Mr. Sirri as an independent consultant. From 1994 to 2004, I was Chief Economist at the Investment Company Institute. Earlier, I was Section Chief and Assistant Director at the Federal Reserve Board and Professor of Economics at Oklahoma State University. I have no material relationship with Bank of America or CMG, aside from serving as IFC, and I am aware of no material relationship with any of their affiliates. To assist me with the report, I engaged NERA Economic Consulting, an independent consulting firm that has had extensive experience in the mutual fund industry. I also have retained Willkie Farr & Gallagher LLP as counsel to advise me in connection with the report. 55 The final element involves providing the Trustees with a written evaluation of the above factors as they relate to the fee negotiation process. C. Organization of the Annual Evaluation The 2006 annual evaluation focuses on the six factors and contains a section for each factor except that CMA's costs and profits from managing the Funds have been combined into a single section. In each section, the discussion of the factor considers and analyzes the available data and other information as they bear upon the fee negotiation process. If appropriate, the discussion in the section may point out certain aspects of the proposed fees that may warrant particular attention from the Trustees. The discussion also may suggest other data, information, and approaches that the Trustees might consider incorporating into the fee negotiation process in future years. In addition to a discussion of the six factors, the report reviews the status of recommendations made in the 2005 IFC evaluation. The 2006 report also summarizes the findings with regard to the six factors and contains a summary of recommendations for possible enhancements to the process. II. Status of 2005 Recommendations The 2005 IFC evaluation contains recommendations aimed at enhancing the evaluation of proposed management fees by Trustees. The section summarizes those recommendations and includes my assessment of the response to the recommendations. 1.Recommendation: Trustees should consider requesting more analytical work from CMG in the preparation of future 15(c) materials. Status: CMG has provided additional analyses to the Trustees on economies of scale, a comparative analysis of institutional and retail management fees, management fee breakpoints, risk-adjusted performance, fee waivers and expense reimbursements, and CMG's costs and profitability. 2.Recommendation: Trustees may wish to consider whether CMG should continue expanding the use of Morningstar or other third party data to supplement CMG's fee and performance analysis that is now based primarily on Lipper reports. Status: CMG has used data from Morningstar Inc. to compare with data from Lipper Inc. ("Lipper") in performing the Trustees' screening procedures. 3.Recommendation: Trustees should consider whether...the fund-by-fund screen...should place comparable emphasis on both basis point and quintile information in their evaluation of the funds...Also, the Trustees should consider incorporating sequences of one year performance into a fund-by-fund screen. Status: CMG has not provided Trustees with results of the screening process using percentiles. CMG has provided Trustees with information on the changes in performance and expenses between 2005 and 2006 and data on one-year returns. 4.Recommendation: Given the volatility of fund performance, the Trustees may want to consider whether a better method exists than th[e] fee waiver process to deal with fund underperformance. Status: It is my understanding that the Trustees have determined to address fund underperformance not only through fee waivers and expense caps but also through discussions with CMG regarding the sources of underperformance. CMG has provided Trustees with an analysis of the relationship between breakpoints, expense reimbursements, and fee waivers. 5.Recommendation: [Seventy-one] percent of funds [have] yet to reach their first management fee breakpoint... Trustees may wish to consider whether the results of my ongoing economies-of-scale work affects the underlying economic assumptions reflected in the existing breakpoint schedules. Status: CMG has prepared a memo for the Trustees discussing its views on the nature and sharing of potential economies of scale. The memo discuses CMG's view that economies of scale arise at the complex level rather than the fund level. The memo also describes steps, including the introduction of breakpoints, taken to share economies of scale with shareholders. CMG's analysis, however, does not discuss specific sources of economies of scale and does not link breakpoints to economies of scale that might be realized as the Funds' assets increase. 56 6.Recommendation: Trustees should continue working with management to address issues of funds that demonstrate consistent or significant underperformance even if the fee levels for the funds are low. Status: Trustees monitor performance on an ongoing basis. III. Findings A. General 1.Based upon my examination of the available information and the six factors, I conclude that the Trustees have the relevant information necessary to evaluate the reasonableness of the proposed management fees for the Funds. CMG has provided the Trustees with relevant materials on the six factors through the 15(c) contract renewal process and in materials prepared for review at Board and Committee meetings. 2.In my view, the process by which the proposed management fees of the Funds have been negotiated in 2006 thus far has been, to the extent practicable, at arms' length and reasonable and consistent with the AOD. B. Nature and Quality of Services, Including Performance 3.The performance of the Funds has been relatively strong, especially that of fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance periods, over 60 percent of the funds have ranked in the top three performance quintiles. 4.The performance of the equity Funds overall, though less concentrated in the top two quintiles than the fixed income Funds, improved in 2006 relative to that in 2005. The fixed-income funds maintained the relatively high performance level of 2005 in 2006. 5.The Funds' overall performance adjusted for risk was significantly stronger than performance unadjusted for risk. Domestic and international equity funds, in particular, moved to higher relative performance rankings after adjusting for risk. 6.The procedure used to construct the performance universe in which each Fund's performance is ranked relative to comparable funds may bias a Fund's ranking upward within that universe. The bias occurs because the performance ranking procedure includes all share classes of multi-class funds in the universe and because the procedure ranks either no-load or A share classes of the Funds. No-load and A share classes generally have lower total expenses than B and C shares (owing to B and C shares having higher distribution/service fees) and thus, given all else, would outperform many of B and C share classes included in the universe. A preliminary analysis that adjusts for the bias results in a downward movement in the relative performance for the Funds but does not change the general finding that the Funds' performance has been strong relative to comparable funds. C. Management Fees Charged by Other Mutual Fund Companies 7.The Funds' management fees and total expenses are generally low relative to those of their peers. At least 56 percent of the Funds are in the first or second quintiles with the lowest fees and expenses and nearly three fourths or more in the first three quintiles. Equity Funds are more highly concentrated in the first three quintiles than fixed-income Funds. 8.The fee and expense rankings as whole are similar to those in 2005 in that the majority of funds are ranked in the top quintiles. Nonetheless, a number of individual funds experienced a change in ranking between 2005 and 2006. This fund-level instability may reflect sensitivity of rankings to the composition of the comparison groups, as the membership of the peer groups typically changed substantially between the two years. 9.The Liberty Money Market Fund VS appears to have a higher management fee structure than that of other Columbia money market funds of comparable asset size. 57 D. Trustees' Fee and Performance Evaluation Process 10.The Trustees' evaluation process identified 21 funds in 2006 for further review based upon their relative performance or expenses. Seventeen of these funds had been subject to review in 2004 or 2005. E. Potential Economies of Scale 11.CMG has prepared a memo for the Trustees containing its views on the sources and sharing of potential economies of scale. CMG views economies of scale as arising at the complex level and would regard estimates of scale economies for individual funds as unreliable. CMG has not, however, identified specific sources of economies of scale nor has it provided any estimates of the magnitude of any economies of scale. In the memo, CMG also describes measures taken by the Trustees and CMG that seek to share any potential economies of scale through breakpoints in management fee schedules, expense reimbursements, fee waivers, enhanced shareholder services, fund mergers, and operational consolidation. These measures, although of significant benefit to shareholders, have not been directly linked in the memo to the existence, sources, and magnitude of economies of scale. F. Management Fees Charged to Institutional Clients 12.CMG has provided Trustees with comparisons of mutual fund management fees and institutional fees based upon standardized fee schedules and upon actual fees. Based upon the information, institutional fees are generally lower than the Funds' management fees. This pattern is consistent with the economics of the two financial products. Data are not available, however, on actual institutional fees at other money managers. Thus, it is not possible to determine the extent to which differences between the Funds' management fees and institutional fees are consistent with those seen generally in the marketplace. G. Revenues, Expenses, and Profits 13.The financial statements and the methodology underlying their construction generally form a sufficient basis for Trustees to evaluate the expenses and profitability of the Funds. IV. Recommendations A. Performance 1.Trustees may wish to consider incorporating risk adjusted measures in their evaluation of performance. CMG has begun to prepare reports for the Trustees with risk adjustments, which could form the basis for formally including the measures in the 15(c) materials. To this end, Trustees may wish to have CMG prepare documents explaining risk adjustments and describing their advantages and disadvantages. 2.Trustees may wish to consider having CMG evaluate the sensitivity of performance rankings to the design of the universe. The preliminary analysis contained in the evaluation suggests that the method employed by Lipper, the source of performance rankings used by the Trustees, may bias performance rankings upward. B. Economies of Scale 3.Trustees may wish to consider having CMG extend its analysis of economies of scale by examining the sources of such economies, if any. Identification of the sources may enable the Trustees and CMG to gauge their magnitude. It also may enable the Trustees and CMG to build upon past work on standardized fee schedules so that the schedules themselves are consistent with any economies of scale and their sources. Finally, an extension of the analysis may enable the Trustees and CMG to develop a framework that coordinates the use of fee waivers and expense caps with the standard fee schedules and with any economies of scale and their sources. C. Institutional Fees 4.Trustees may wish to consider encouraging CMG to build further upon its expanded analysis of institutional fees by refining the matching of institutional accounts with mutual funds, by dating the establishment of each institutional account, and by incorporating other accounts, such as subadvisory relationships, trusts, offshore funds, and separately managed accounts into the analysis. 58 D. Profitability 5.Trustees may wish to consider requesting that CMG expand the reporting of revenues and expenses to include more line-item detail for management and administration, transfer agency, fund accounting, and distribution. 6.Trustees may wish to consider requesting that CMG provide a statement of its operations in the 15(c) materials. 7.Trustees may wish to consider the treatment of the revenue sharing with the Private Bank of Bank of America in their review of CMG's profitability. Respectfully submitted, John D. Rea 59 Appendix Sources of Information Used in the Evaluation The following list generally describes the sources and types of information that were used in preparing this report. 1. Performance, management fees, and expense ratios for the Funds and comparable funds from other fund complexes from Lipper and CMG. The sources of this information were CMG and Lipper; 2. CMG's expenses and profitability obtained directly from CMG; 3. Information on CMG's organizational structure; 4. Profitability of publicly traded asset managers from Lipper; 5. Interviews with CMG staff, including members of senior management, legal staff, heads of affiliates, portfolio managers, and financial personnel; 6. Documents prepared by CMG for Section 15(c) contract renewals in 2005 and 2006; 7. Academic research papers, industry publications, professional materials on mutual fund operations and profitability, and SEC releases and studies of mutual fund expenses 8. Interviews with and documents prepared by Ernst & Young LLP in its review of the Private Bank Revenue Sharing Agreement; 9. Discussions with Trustees and attendance at Board and committee meetings during which matters pertaining to the evaluation were considered. In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data management and analysis. NERA has extensive experience in the mutual fund industry that provides unique insights and special knowledge pertaining to my independent analysis of fees, performance, and profitability. I have also retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher LLP as outside counsel to advise me in connection with my evaluation. Finally, meetings and discussions with CMG staff were informative. My participation in Board and committee meetings in which Trustees and CMG management discussed issues relating to management contracts were of great benefit to the preparation of the evaluation. 60 Important Information About This Report Columbia Income Fund The fund mails one shareholder report to each shareholder address.

Wilson President, Columbia Funds Dear Shareholder: Investing is a long-term process and we are pleased that you have chosen to include the Columbia family of funds in your overall financial plan. Your financial advisor can help you establish an appropriate investment portfolio and periodically review that portfolio. A well balanced portfolio is one of the keys to successful long-term investing. Your portfolio should be diversified across different asset classes and market segments and your chosen asset allocation should be appropriate for your investment goals, risk tolerance and time horizons. However, creating an investment strategy is not a one-step process. From time to time, you'll need to re-evaluate your strategy to determine whether your investment needs have changed. Most experts recommend giving your portfolio a "check-up" every year. As you begin your portfolio check-up, consider whether you have experienced any major life events since the last time you assessed your portfolio. You may need to tweak your strategy if you have: .. Gotten married or divorced .. Added a child to your family .. Made a significant change in employment .. Entered or moved significantly closer to retirement .. Experienced a serious illness or death in the family .. Taken on or paid off substantial debt It's important to remember that over time, performance in different market segments will fluctuate. These shifts can cause your portfolio balance to drift away from your chosen asset allocation. A periodic portfolio check-up can help make sure your portfolio stays on track. Remember that asset allocation does not ensure a profit or guarantee against loss. You'll also want to analyze the individual investments in your portfolio. Of course, performance should be a key factor in your analysis, but it's not the only factor to consider. Make sure the investments in your portfolio line up with your overall objectives and risk tolerance. Be aware of changes in portfolio management and pay special attention to any funds that have made significant shifts in their investment strategy. We hope this information will help you, in working with your financial advisor, to stay on track to reach your investment goals. Thank you for your business and for your continued confidence in Columbia Funds. Sincerely, /s/ Christopher L. Wilson Christopher L. Wilson President, Columbia Funds Economic Update - Columbia Intermediate Bond Fund Summary For the 12-month period that ended March 31, 2007 . Investment-grade bonds rebounded as yields declined, lifting the Lehman Brothers U.S. Aggregate Bond Index to a respectable return. High-yield bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led the U.S. fixed-income markets. Lehman Merrill Lynch Index Index [GRAPHIC] [GRAPHIC] 6.59% 11.45% . The broad US stock market, as measured by the S&P 500 Index, returned 11.83%. Stock markets outside the United States were even stronger, as measured by the MSCI EAFE Index. S&P Index MSCI Index [GRAPHIC] [GRAPHIC] 11.83% 20.20% The Lehman Brothers U.S. 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, and 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 U.S. High Yield, Cash Pay Index tracks the performance of non-investment-grade corporate bonds. The S&P 500 Index tracks the performance of 500 widely held, large-capitalization US stocks. The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. 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. US economic growth advanced at a modest pace during the 12-month period that began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on the economy throughout the period, with few signs that relief was imminent. Energy prices trended downward, but rose again late in the period, and core inflation moved higher. Yet, many economic indicators remained positive. Job growth, for example, was relatively strong, as the labor markets added an average of 164,000 new jobs each month over the period and the unemployment rate declined to 4.4%. Personal income rose and consumer spending continued to expand, albeit at a slower pace as the period wore on. Against this backdrop, economic growth averaged around 2.2% for the 12-month period. Between April and June 2006, the Federal Reserve Board (the Fed) raised a key short-term interest rate, the federal funds rate, twice -- to 5.25%. But after its June meeting, the Fed turned cautious in the face of slower economic growth and held the federal funds rate steady. Investors reacted favorably to the prospect of stable or lower interest rates and fueled a rally that moved stock prices higher and gave a boost to the bond market as well. Bonds bounced back Although bond yields moved higher early in the period, most segments of the US bond market delivered respectable returns, as prices rose and yields declined in reaction to the Fed's mid-year decision to put further short-term rate increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether for the bond market, ended the 12-month period at 4.63% -- somewhat lower than where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond Index returned 6.59%. High-yield bonds led the US fixed-income markets, reflecting investor confidence about the overall resilience of the economy despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay Index returned 11.45%. Despite late set-back, stocks moved solidly higher Stock prices rose at an above-average pace during the 12-month period covered by this report. The S&P 500 Index, a broad measure of common stock performance, rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap stocks, as measured by their respective Russell indices. Foreign stock markets were even stronger than the US market. The MSCI EAFE Index, which tracks stock market performance in industrialized countries outside the United States and Canada, returned 20.20%, despite a volatile stretch late in the period when the US and many foreign stock markets retreated in response to a sharp decline in the Chinese market and other market-specific factors. /1/10-year Treasury note used solely as a benchmark for long-term interest rates.

The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower. Prior to August 22, 2005, new purchases of Class A shares had a maximum initial sales charge of 4.75%. The 5 &10 year average annual returns with sales charge as of 3/31/07 include the previous sales charge of 4.75%. The 1 year return with sales charge as of 3/31/07 includes the new sales charge of 3.25%. Performance results reflect any waivers or reimbursements of fund expenses by the investment advisor and/or any of its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. All results shown assume reinvestment of distributions. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. Class R and Z shares are sold at net asset value with no Rule 12b-1 fees. Class R and Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectus for details. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The returns of Class A shares include returns of the fund's Class Z shares (the oldest existing fund share class) for periods prior to the inception of Class A shares. The returns of Class B and Class C shares include returns of the fund's Class A shares for period prior to the inception of Class B and Class C shares, respectively. The returns of Class B and Class C shares also include returns of the fund's Class Z shares for periods prior to the inception of Class A shares. The returns for Class R shares include returns of the fund's Class A shares for periods prior to the inception of Class R shares. The returns of Class R shares also include the returns of the fund's Class Z shares for periods prior to the inception of Class A shares. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A, Class B, Class C or Class R shares, or between Class A shares and Class B, Class C or Class R shares. If differences in expenses had been reflected, the returns shown for Class A, Class B, Class C and Class R shares for periods prior to the inception of Class A, Class B, Class C and Class R shares, respectively, would have been lower. Class A shares were initially offered on July 31, 2000, Class B and Class C shares were initially offered on February 1, 2002, Class R shares were initially offered on January 23, 2006, and Class Z shares were initially offered on December 5, 1978. 2 Understanding Your Expenses - Columbia Intermediate Bond Fund 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. 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 fees, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand the ongoing costs of investing in the fund and to compare these costs with the ongoing 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 $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated based on the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing cost of investing in a fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. 10/01/06 - 03/31/07 Account value at the Account value at the Expenses paid Fund's annualized beginning of the period ($) end of the period ($) during the period ($) expense ratio (%) - ------------------------------------------------------------------------------------------------- Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,027.08 1,020.39 4.60 4.58 0.91 Class B 1,000.00 1,000.00 1,023.29 1,016.65 8.37 8.35 1.66 Class C 1,000.00 1,000.00 1,023.98 1,017.40 7.62 7.59 1.51 Class R 1,000.00 1,000.00 1,025.78 1,019.15 5.86 5.84 1.16 Class Z 1,000.00 1,000.00 1,028.32 1,021.64 3.34 3.33 0.66 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 investment advisor and/or any of its affiliates not waived or reimbursed a portion of expenses, account value at the end of the period would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical examples provided may not help you determine the relative total costs of owning shares of different funds. If these transaction costs were included, your costs would have been higher. 3 Portfolio Managers' Report - Columbia Intermediate Bond Fund Performance data quoted represents past performance and current performance may be lower or higher.

For the 12-month period that ended March 31, 2007, Class A shares of Columbia Intermediate Bond Fund returned 6.21% without sales charge. The fund's return was lower than the 6.59% return of its benchmark, the Lehman Brothers U.S. Aggregate Bond Index, for the same period./1/ The fund incurs fees that the index does not. The fund exceeded the average return of its peer group, the Lipper Intermediate Investment Grade Debt Funds Classification, which was 6.08% for the period./2/ Strong returns from high-yield investments helped create this performance advantage versus the fund's peer group. The past 12 months were a fairly stable period for the fixed-income markets. Three months into the period, the Federal Reserve Open Market Committee (the Fed) suspended its two-year-long string of short-term interest rate hikes, and stayed on the sidelines for the remainder of the period. Meanwhile, inflation remained moderate enough to bring long-term rates down slightly. The net result was a healthy bond market. While long-term bonds tended to outperform issues with shorter maturities, solid gains were posted at all points of the maturity spectrum. Steady economic growth favored corporate bonds The national economy remained in a sweet spot characterized by strong growth and the absence of undue inflationary pressures. The economy's steady growth created a favorable environment for corporate bonds, consistent with a general trend in which fixed-income investors were rewarded for assuming credit risk. In particular, high-yield bonds were the top performing bond market sector during the period. Our decision to overweight the high-yield sector helped the fund's performance relative to other intermediate bond funds. However, this reward for risk-taking did not extend to the mortgage market. Toward the end of the period, a surge in foreclosures experienced by subprime lenders resulted in significant losses for low-quality mortgage pools. While the fund's exposure to subprime securities was limited, many of its mortgage holdings lost ground as investors worried that problems could spill over to other areas of the market. The fund's sector decisions experienced mixed results during the period. Positions in the financial sector helped performance for the first six months, then hampered performance in the second half, above and beyond subprime concerns. A decision to underweight the insurance sector also hampered performance as major carriers delivered above-average performance after a mild hurricane year. We may consider adding to the fund's insurance holdings because of the balance sheet improvements created by the limited payouts of the past year and limited subprime exposure. In addition, we believe insurers appear to be less likely than other financial companies to be candidates for a private equity transaction. /1/The Lehman Brothers U.S. 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, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity.

Looking ahead At the end of the period, the fund's positioning reflected our generally positive view of the corporate bond market, supported by solid corporate earnings and economic environment. We plan to keep our high-yield exposure in line with our competitive peers, and would look to retain our slightly above-average exposure to investment-grade corporate issues. The bond market still faces an elevated risk of shareholder-friendly leveraged transactions. Yet, we believe that such risks are generally priced into today's yields. 5 Fund Profile - Columbia Intermediate Bond Fund Performance data quoted represents past performance and current performance may be lower or higher.

The outlook for this fund may differ from that presented for other Columbia Funds. Performance for different classes of shares will vary based on differences in sales charges and fees associated with each class. For standardized performance, please refer to Performance Information page. Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yield and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa. Investing in high-yield securities (commonly known as "junk" bonds) offers the potential for high current income and attractive total return but involves certain risks. Changes in economic conditions or other circumstances may adversely affect a junk bond issuer's ability to make principal and interest payments. Rising interest rates tend to lower the value of all bonds. High-yield bonds issued by foreign entities have greater potential risks, including less regulation, currency fluctuations, economic instability and political developments. 6 Investment Portfolio - Columbia Intermediate Bond Fund March 31, 2007 Corporate Fixed-Income Bonds & Notes - 47.5% Par ($) Value ($) Basic Materials - 1.4% Chemicals - 0.3% BCP Crystal US Holdings Corp. 9.625% 06/15/14 285,000 323,737 Chemtura Corp. 6.875% 06/01/16 545,000 527,287 Dow Chemical Co. 6.000% 10/01/12 2,490,000 2,567,319 EquiStar Chemicals LP 10.625% 05/01/11 650,000 685,750 Huntsman International LLC 6.875% 11/15/13 (a) 205,000 282,065 7.875% 11/15/14 (a) 290,000 299,788 Ineos Group Holdings PLC 8.500% 02/15/16 (a) 500,000 478,750 Lyondell Chemical Co. 8.000% 09/15/14 265,000 277,588 8.250% 09/15/16 385,000 411,950 MacDermid, Inc. 9.500% 04/15/17 (a)(b) 275,000 281,875 Mosaic Co. 7.625% 12/01/16 (a) 665,000 701,575 NOVA Chemicals Corp. 6.500% 01/15/12 470,000 447,675 ----------------------------- ---------- ---------- Chemicals Total 7,285,359 Forest Products & Paper - 0.7% Abitibi-Consolidated, Inc. 8.375% 04/01/15 445,000 418,300 Norske Skog Canada Ltd. 7.375% 03/01/14 1,000,000 967,500 Domtar, Inc. 7.125% 08/15/15 505,000 502,475 Georgia-Pacific Corp. 8.000% 01/15/24 565,000 567,825 NewPage Corp. 10.000% 05/01/12 280,000 306,250 12.000% 05/01/13 275,000 298,375 Weyerhaeuser Co. 7.375% 03/15/32 12,405,000 12,995,192 ----------------------------- ---------- ---------- Forest Products & Paper Total 16,055,917 Metals & Mining - 0.4% FMG Finance Ltd. 10.625% 09/01/16 (a) 795,000 914,250 Freeport-McMoRan Copper & Gold, Inc. 8.375% 04/01/17 1,120,000 1,211,000 Vale Overseas Ltd. 6.250% 01/23/17 3,730,000 3,800,714 6.875% 11/21/36 1,935,000 1,998,249 ----------------------------- ---------- ---------- Metals & Mining Total 7,924,213 Basic Materials Total 31,265,489 Communications - 5.8% Media - 2.5% Advanstar Communications, Inc. 12.000% 02/15/11 555,000 578,588 15.000% 10/15/11 (c) 130,000 135,850 See Accompanying Notes to Financial Statements. 7 Columbia Intermediate Bond Fund March 31, 2007 Corporate Fixed-Income Bonds & Notes (continued) Par ($) Value ($) Communications (continued) Media (continued) Atlantic Broadband Finance LLC 9.375% 01/15/14 470,000 480,575 Cablevision Systems Corp. 8.000% 04/15/12 455,000 461,825 Charter Communications Holdings I LLC 9.920% 04/01/14 940,000 836,600 11.000% 10/01/15 500,000 518,750 Clear Channel Communications, Inc. 4.900% 05/15/15 230,000 193,375 5.500% 12/15/16 360,000 303,695 7.650% 09/15/10 6,890,000 7,275,309 CMP Susquehanna Corp. 9.875% 05/15/14 (a) 475,000 486,875 CSC Holdings, Inc. 7.625% 04/01/11 (d) 805,000 825,125 7.625% 07/15/18 215,000 217,150 DirecTV Holdings LLC 6.375% 06/15/15 595,000 565,250 EchoStar DBS Corp. 6.625% 10/01/14 800,000 805,000 Lamar Media Corp. 6.625% 08/15/15 1,145,000 1,116,375 LIN Television Corp. 6.500% 05/15/13 365,000 357,244 PriMedia, Inc. 8.000% 05/15/13 560,000 579,600 Quebecor Media, Inc. 7.750% 03/15/16 565,000 580,538 R.H.

Organization Columbia Intermediate Bond Fund (the "Fund"), a series of Columbia Funds Series Trust I (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 its total return by pursuing current income and opportunities for capital appreciation. Fund Shares The Fund may issue an unlimited number of shares and offers five classes of shares: Class A, Class B, Class C, Class R 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 3.25% 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 3.00% based upon the holding period after purchase. Class B shares will convert to Class A shares eight years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class R and Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class R and Class Z shares, as described in the Fund's prospectus. Note 2. Significant Accounting Policies 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. Forward currency exchange contracts are valued at the prevailing forward exchange rate of the underlying securities. 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 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. In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is evaluating the impact the application of SFAS 157 will have on the Fund's financial statement disclosures. Security Transactions Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the 40 Columbia Intermediate Bond Fund March 31, 2007 specific identification method for both financial statement and federal income tax purposes. Futures Contracts The Fund may invest in futures contracts to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or derived from, the value of the underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The fund typically uses derivatives in an effort to achieve more efficiently economic exposure similar to those it could have achieved through the purchase and sale of fixed income securities. 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 ("Columbia"), the Fund's investment adviser, 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. Repurchase Agreements The Fund may engage in repurchase agreement transactions with institutions that Columbia has determined are creditworthy. The Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Columbia is responsible for determining that 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. Mortgage Dollar Roll Transactions The Fund may enter into mortgage "dollar rolls" in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date not exceeding 120 days. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase (often referred to as the "drop") or fee income plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. Unless such benefits exceed the income, capital appreciation and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared with what such performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund will hold and maintain in a segregated account until the settlement date, cash or liquid securities in an amount equal to the forward purchase price. The Fund's policy is to record the components of mortgage dollar rolls using "to be announced" mortgage-backed securities ("TBA Dollar Rolls"). For financial reporting and tax purposes, the Fund treats mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing. Mortgage dollar rolls involve certain risks. If the broker-dealer to whom the Fund sells the security becomes insolvent, the Fund's right to purchase or repurchase the mortgage-related securities may be restricted and the instrument which the Fund is required to repurchase may be worth less than an instrument which the Fund originally held. Successful use of mortgage dollar rolls may depend upon the investment advisor's ability to predict correctly interest rates and mortgage prepayments. For these reasons, there is no 41 Columbia Intermediate Bond Fund March 31, 2007 assurance that mortgage dollar rolls can be successfully employed. 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 holds until settlement date, in a segregated account, cash or liquid securities in an amount equal to the delayed delivery commitment. Income Recognition Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Fee income attributable to mortgage dollar roll transactions is accrued over the term of the transaction. Forward Foreign Currency Exchange Contracts Forward foreign currency exchange contracts are agreements to exchange one currency for another at a future date at a specified price. These contracts are used to minimize the exposure to foreign exchange rate fluctuations during the period between trade and settlement date. The Fund may utilize forward foreign currency exchange contracts in connection with the settlement of purchases and sales of securities. The Fund may also enter into these contracts to hedge certain other foreign currency denominated assets. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell are used to hedge the Fund's investments against currency fluctuations. Forward currency contracts are valued daily at the current exchange rate of the underlying currency, resulting in unrealized gains (losses) which become realized at the time the foreign currency contracts are closed or mature. Realized and unrealized gains (losses) arising from such transactions are included in net realized and unrealized gains (losses) on foreign currency transactions. The use of forward currency contracts does not eliminate fluctuations in the prices of the Fund's portfolio securities. Although the maximum potential loss from such contracts is the aggregate face value in U.S. dollars at the time the contract was opened, exposure is typically limited to the change in value of the contract (in U.S. dollars) over the period it remains open. The Fund could also be exposed to risk if the counterparties of the contracts are unable to fulfill the terms of the contracts. The counterparty risk exposure is, therefore, closely monitored and contracts are only executed with high credit quality financial institutions. Stripped Securities Stripped mortgage-backed securities are derivative multi-class mortgage securities structured so that one class receives most, if not all, of the principal from the underlying mortgage assets, while the other class receives most, if not all, of the interest and the remainder of the principal. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in an interest-only security. The market value of these securities can be extremely volatile in response to changes in interest rates. Credit risk reflects the risk that the Fund may not receive all or part of its principal because the issuer or credit enhancer has defaulted on its obligation. 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 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 the ex-date. Dividends from net investment income are declared daily and 42 Columbia Intermediate Bond Fund March 31, 2007 paid monthly. Net realized capital gains, if any, are distributed at least annually. Indemnification In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Fund's organizational documents and by contract, the trustees and officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these representations, warranties and indemnities to be minimal. 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 March 31, 2007, permanent book and tax basis differences resulting primarily from differing treatments for discount accretion/ premium amortization on debt securities and market discount reclasses were identified and reclassified among the components of the Fund's net assets as follows: Overdistributed Net Accumulated Paid-In Investment Income Net Realized Loss Capital $2,768,693 $(2,768,691) $(2) Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. The tax character of distributions paid during the years ended March 31, 2007 and March 31, 2006 was as follows: March 31, 2007 March 31, 2006 Distributions paid from: Ordinary Income* $98,357,822 $66,652,649 *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of March 31, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Net Ordinary Long-Term Unrealized Income Capital Gains Appreciation* $4,832,862 $ -- $1,069,436 *The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales and differing treatment for discount accretion/premium amortization on debt securities. Unrealized appreciation and depreciation at March 31, 2007, based on cost of investments for federal income tax purposes were: Unrealized appreciation $ 19,423,096 Unrealized depreciation (18,353,660) Net unrealized appreciation $ 1,069,436 The following capital loss carryforwards, determined as of March 31, 2007, 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 2013 $ 6,075,470 2014 3,776,565 2015 8,375,463 ----------- Total $18,227,498 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 March 31, 2007, post-October capital losses of $744,787 attributed to security transactions were deferred to April 1, 2007. 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 No. 109 (the "Interpretation"). This Interpretation is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006 and is to be applied to open tax positions upon initial adoption. This Interpretation prescribes a minimum recognition threshold and measurement method for the 43 Columbia Intermediate Bond Fund March 31, 2007 financial statement recognition of tax positions taken or expected to be taken in a tax return and also requires certain expanded disclosures. Management is evaluating 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, an indirect, wholly-owned subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to the Fund. 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 $1 billion 0.35% $1 billion to $1.5 billion 0.30% $1.5 billion to $3 billion 0.29% $3 billion to $6 billion 0.28% Over $6 billion 0.27% For the year ended March 31, 2007, the Fund's effective investment advisory fee rate was 0.32% of the Fund's average daily net assets. Administration Fee Columbia provides administrative and other services to the Fund for a monthly administration fee at the annual rate of 0.15% of the Fund's average daily net assets. Pricing and Bookkeeping Fees Effective December 15, 2006, the Fund entered into a Financial Reporting Services Agreement with State Street Bank & Trust Company ("State Street") and Columbia (the "Financial Reporting Services Agreement") pursuant to which State Street provides financial reporting services to the Fund. Also effective December 15, 2006, the Fund entered into an Accounting Services Agreement with State Street and Columbia (collectively with the Financial Reporting Services Agreement, the "State Street Agreements") pursuant to which State Street provides accounting services to the Fund. Under the State Street Agreements, the Fund pays State Street an annual fee of $38,000 paid monthly plus an additional monthly fee based on an annualized percentage rate of average daily net assets of the Fund for the month. Under the State Street Agreements, the combined fee payable to State Street by the Fund will not exceed $140,000 annually. The Fund also reimburses State Street for certain out-of-pocket expenses. Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping Oversight and Services Agreement (the "Services Agreement") with Columbia. Under the Services Agreement Columbia provides services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides oversight of the accounting and financial reporting services provided by State Street. Under the Services Agreement, the Fund reimburses Columbia for out-of-pocket expenses and direct internal costs relating to accounting oversight and for services related to Fund expenses and the requirements of the Sarbanes-Oxley Act of 2002. Prior to December 15, 2006, Columbia was responsible for providing pricing and bookkeeping services to the Fund under a pricing and bookkeeping agreement. Under its pricing and bookkeeping agreement with the Fund, Columbia was entitled to receive an annual fee at the same fee structure described above under the State Street Agreements. Under separate agreements between Columbia and State Street, Columbia delegated certain functions to State Street. As a result of the delegation, the total fees payable under the pricing and bookkeeping agreement (other than certain reimbursements paid to Columbia and discussed below) were paid to State Street. The Fund also reimbursed 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 March 31, 2007, the Fund's effective pricing and bookkeeping fee rate, inclusive of out-of-pocket expenses, was 0.011% 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 44 Columbia Intermediate Bond Fund March 31, 2007 subsidiary of BOA, provides shareholder services to the Fund and 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 reimbursement of certain 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 other parties (including affiliates of BOA) for services to those accounts. The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursements for such fees from the Fund. 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. For the year ended March 31, 2007, the Fund's effective transfer agent fee rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was 0.10% of the Fund's average daily net assets. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. For the year ended March 31, 2007, the Distributor has retained net underwriting discounts of $11,230 on sales of the Fund's Class A shares and net CDSC fees of $163, $211,917 and $2,596 on Class A, Class B and Class C share redemptions, respectively. The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Fund. The Plan also requires the payment of a monthly distribution fee to the Distributor at the annual rates of 0.10%, 0.75%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class B, Class C and Class R shares, respectively. The Distributor has voluntarily agreed to waive the Class A share distribution fee. The Distributor has also voluntarily agreed to waive a portion of the Class C share distribution fee so that it will not exceed 0.60% annually of Class C average daily net assets. These waivers may be modified or terminated by the Distributor at any time. 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 in the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. Fees Paid to Officers and Trustees All officers of the Fund are employees of Columbia or its affiliates and, with the exception of the Fund's Chief Compliance Officer, receive no compensation from the Fund. The Board of Trustees has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund, along with other affiliated funds, pays its pro-rata share of the expenses associated with the Chief Compliance Officer. The Fund's expenses for the Chief Compliance Officer will not exceed $15,000 per year. The Fund's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Fund's assets. Other Columbia provides certain services to the Fund related to the requirements of the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund paid $2,875 to Columbia for such services. This amount is included in "Other expenses" in the Statement of Operations. Note 5. Portfolio Information For the year ended March 31, 2007, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $3,191,983,302 and $2,610,517,111, 45 Columbia Intermediate Bond Fund March 31, 2007 respectively, of which $1,631,736,771 and $1,559,812,014, respectively, were U.S. Government securities. Note 6. Shares of Beneficial Interest As of March 31, 2007, the Fund had one shareholder that held 41.9% of the shares outstanding. The shares were beneficially owned by participant accounts over which BOA and/or its affiliates had either sole or joint investment discretion. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. As of March 31, 2007, the Fund had two shareholders that held 20.0% of the shares outstanding. These shares were beneficially owned by participant accounts over which BOA and/or its affiliates did not have investment discretion. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. Note 7. Line of Credit The Trust and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured line of credit, both provided by State Street. Borrowings are available for temporary or emergency purposes. Interest on the committed line of credit is charged to each participating fund based on the fund's 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 committed line of credit. Interest on the uncommitted line of credit is charged to each participating fund based on the fund's borrowings at a variable rate per annum equal to the Federal Funds Rate plus a spread, as determined and quoted by State Street at the time of the request for a loan. A one-time structuring fee of $30,000 is also accrued and apportioned to each fund participating in the uncommitted line of credit based on the average net assets of the participating funds. In addition, if the uncommitted line of credit is extended for an additional period, an annual administration fee of $15,000 will be charged and apportioned among the participating fund. The commitment fee and structuring fee are included in "Other expenses" in the Statement of Operations. For the year ended March 31, 2007, the Fund did not borrow under this arrangement. Note 8. Securities Lending The Fund commenced a securities lending program in August 2006 and may lend its securities to certain approved brokers, dealers and other financial institutions. Each loan is collateralized by cash, in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The collateral received is invested and the income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, is paid to the Fund. Generally, in the event of borrower default, the Fund has the right to use the collateral to offset any losses incurred. In the event the Fund is delayed or prevented from exercising its right to dispose of the collateral, there may be a potential loss to the Fund. The Fund bears the risk of loss with respect to the investment of collateral. Note 9. Other During the year ended March 31, 2007, the Fund had a realized investment loss in the amount of $135 due to a trading error. Columbia voluntarily reimbursed the Fund for the loss. Note 10. Other Related Party Transactions During the year ended March 31, 2007, the Fund used Bank of America Securities, a wholly-owned subsidiary of BOA, as a broker. No commissions were paid to Bank of America Securities during the period. Note 11. Disclosure of Significant Risks and Contingencies 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. 46 Columbia Intermediate Bond Fund March 31, 2007 Sector Focus Companies that are in different but closely related industries are sometimes described as being in the same sector. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector. During such times, the Fund will have greater exposure to the economic and market events affecting such sector than if it were more broadly invested across multiple sectors. 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") on matters relating to mutual fund trading. The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". 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 that was developed by an independent distribution consultant and approved by the SEC on April 6, 2007. 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 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 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. 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 were not dismissed. On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that certain conduct, 47 Columbia Intermediate Bond Fund March 31, 2007 including market timing, entitled Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was removed to federal court in Massachusetts and the federal Judicial Panel 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 settlement is subject to court approval. In 2004, the Columbia Funds' adviser and distributor and certain affiliated entities and individuals 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. Certain Columbia Funds were named as nominal defendants. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment in favor of the defendants. The plaintiffs appealed to the United States Court of Appeals for the First Circuit on December 30, 2005. A stipulation and settlement agreement dated January 19, 2007 was filed in the First Circuit on February 14, 2007, with a joint stipulation of dismissal and motion for remand to obtain district court approval of the settlement. That joint motion was granted and the appeal was dismissed. On March 6, 2007, the case was remanded to the District Court. On May 11, 2007, the District Court entered a preliminary approval order which granted preliminary approval of the settlement. A final settlement hearing, at which the District Court will determine whether the proposed settlement should be finally approved and the action dismissed on the merits with prejudice, is scheduled for September 18, 2007. The terms of the settlement, if finally approved, will require payments by the funds' adviser and/or its affiliates, including payment of plaintiffs' attorneys' fees and notice to class members. In the event that the settlement is not finally approved, the plaintiffs may elect to go forward with their appeal and no opinion is expressed regarding the likely outcome or financial impact of such an appeal on any fund. 48 Report of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia Intermediate Bond 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 Intermediate Bond Fund (the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2007 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for the periods prior to July 1, 2003 were audited by another independent registered public accounting firm whose report dated August 19, 2003 expressed an unqualified opinion on those statements.

After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements. In addition, the Board, including the Independent Trustees, considers matters bearing on the Agreements at most of its other meetings throughout the year and meets regularly with the heads of each investment area within Columbia. Through the Board's Investment Oversight Committees, Trustees also meet with selected fund portfolio managers at various times throughout the year. The Trustees receive and review all materials that they, their legal counsel or Columbia, the funds' investment adviser, believe to be reasonably necessary for the Trustees to evaluate the Agreements and determine whether to approve the continuation of the Agreements. Those materials generally include, among other items, (i) information on the investment performance of each fund relative to the performance of peer groups of mutual funds and the fund's performance benchmarks, (ii) information on each fund's advisory fees and other expenses, including information comparing the fund's expenses to those of peer groups of mutual funds and information about any applicable expense caps and fee "breakpoints," (iii) information about the profitability of the Agreements to Columbia, including potential "fall-out" or ancillary benefits that Columbia and its affiliates may receive as a result of their relationships with the funds and (iv) information obtained through Columbia's response to a questionnaire prepared at the request of the Trustees by counsel to the funds and independent legal counsel to the Independent Trustees. The Trustees also consider other information such as (v) Columbia's financial results and financial condition, (vi) each fund's investment objective and strategies and the size, education and experience of Columbia's investment staffs and their use of technology, external research and trading cost measurement tools, (vii) the allocation of the funds' brokerage, if any, and the use of "soft" commission dollars to pay for research products and services, (viii) Columbia's resources devoted to, and its record of compliance with, the funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (ix) Columbia's response to various legal and regulatory proceedings since 2003 and (x) the economic outlook generally and for the mutual fund industry in particular. In addition, the Advisory Fees and Expenses Committee confers with the funds' independent fee consultant and reviews materials relating to the funds' relationships with Columbia provided by the independent fee consultant. Throughout the process, the Trustees have the opportunity to ask questions of and request additional materials from Columbia and to consult with independent legal counsel to the Independent Trustees and the independent fee consultant. The Board of Trustees most recently approved the continuation of the Agreements at its October, 2006 meeting, following meetings of the Advisory Fees and Expenses Committee held in August, September and October, 2006. In considering whether to approve the continuation of the Agreements, the Trustees, including the Independent Trustees, did not identify any single factor as determinative, and each weighed various factors as he or she deemed appropriate. The Trustees considered the following matters in connection with their approval of the continuation of the Agreements: The nature, extent and quality of the services provided to the funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by Columbia and its affiliates to the funds and the resources dedicated to the funds by Columbia and its affiliates. Among other things, the Trustees considered (i) Columbia's ability (including its personnel and other resources, compensation programs for personnel involved in fund management, reputation and other attributes) to attract and retain highly qualified research, advisory and supervisory investment professionals; (ii) the portfolio management services provided by those investment professionals; and (iii) the trade execution services provided on behalf of the funds. For each fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the continuation of the Agreements. 54 Investment performance of the funds and Columbia. The Trustees reviewed information about the performance of each fund over various time periods, including information prepared by an independent third party that compared the performance of each fund to the performance of peer groups of mutual funds and performance benchmarks. The Trustees also reviewed a description of the third party's methodology for identifying each fund's peer group for purposes of performance and expense comparisons. The Trustees also considered additional information that the Advisory Fees and Expenses Committee requested from Columbia relating to funds that presented relatively weaker performance and/or relatively higher expenses. In the case of each fund whose performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Trustees concluded that other factors relevant to performance were sufficient, in light of other considerations, to warrant continuation of the fund's Agreements. Those factors varied from fund to fund, but included one or more of the following: (i) that the fund's performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the fund's investment strategy and policies and that the fund was performing as expected, given these investment decisions, market conditions and the fund's investment strategy; (iii) that the fund's performance was competitive when compared to other relevant performance benchmarks or peer groups; (iv) that Columbia had taken or was taking steps designed to help improve the fund's investment performance, including, but not limited to, replacing portfolio managers or modifying investment strategies; and (v) that the fund was proposed to be reorganized into another fund, and that such reorganization would result in a reduction in fund expenses. The Trustees also considered Columbia's performance and reputation generally, the funds' performance as a fund family generally, and Columbia's historical responsiveness to Trustee concerns about performance and Columbia's willingness to take steps intended to improve performance. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of each fund and Columbia was sufficient, in light of other considerations, to warrant the continuation of the Agreement(s) pertaining to that fund. The costs of the services provided and profits realized by Columbia and its affiliates from their relationships with the funds. The Trustees considered the fees charged to the funds for advisory services as well as the total expense levels of the funds. That information included comparisons (provided by management and by an independent third party) of each fund's advisory fees and total expense levels to those of the fund's peer groups and information about the advisory fees charged by Columbia to comparable institutional accounts. In considering the fees charged to those accounts, the Trustees took into account, among other things, management's representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for Columbia, and the additional resources required to manage mutual funds effectively. In evaluating each fund's advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the fund. The Trustees considered existing advisory fee breakpoints, and Columbia's use of advisory fee waivers and expense caps, which benefited a number of the funds. The Trustees also noted management's stated justification for the fees charged to the funds, which included information about the investment performance of the funds and the services provided to the funds. The Trustees also considered the compensation directly or indirectly received by Columbia and its affiliates from their relationships with the funds. The Trustees reviewed information provided by management as to the profitability to Columbia and its affiliates of their relationships with each fund, and information about the allocation of expenses used to calculate profitability. When reviewing profitability, the Trustees also considered court cases in which adviser profitability was an issue in whole or in part, the performance of the relevant funds, the expense level of each fund, and whether Columbia had implemented breakpoints and/or expense caps with respect to the fund. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each fund, and the related profitability to Columbia and its affiliates of their relationships with the fund, supported the continuation of the Agreement(s) pertaining to that fund. 55 Economies of Scale. The Trustees considered the existence of any economies of scale in the provision by Columbia of services to each fund, to groups of related funds, and to Columbia's investment advisory clients as a whole and whether those economies were shared with the funds through breakpoints in the investment advisory fees or other means, such as expense waivers/reductions and additional investments by Columbia in investment, trading and compliance resources. The Trustees noted that many of the funds benefited from breakpoints, expense caps, or both. In considering those issues, the Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to Columbia and its affiliates of their relationships with the funds, as discussed above. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the funds supported the continuation of the Agreements. Other Factors. The Trustees also considered other factors, which included but were not limited to the following: .. the extent to which each fund had operated in accordance with its investment objective and investment restrictions, the nature and scope of the compliance programs of the funds and Columbia and the compliance-related resources that Columbia and its affiliates were providing to the funds; .. the nature, quality, cost and extent of administrative and shareholder services performed by Columbia and its affiliates, both under the Agreements and under separate agreements for the provision of transfer agency and administrative services; .. so-called "fall-out benefits" to Columbia and its affiliates, such as the engagement of its affiliates to provide distribution, brokerage and transfer agency services to the funds, and the benefits of research made available to Columbia by reason of brokerage commissions generated by the funds' securities transactions, as well as possible conflicts of interest associated with those fall-out and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor those possible conflicts of interest; and .. the draft report provided by the funds' independent fee consultant, which included information about and analysis of the funds' fees, expenses and performance. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel and the independent fee consultant, the Trustees, including the Independent Trustees, approved the continuance of each of the Agreements through October 31, 2007. 56 Summary of Management Fee Evaluation by Independent Fee Consultant Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between the Office of Attorney General of New York State and Columbia Management Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006 I. Overview Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors, Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates that CMA may manage or advise a Columbia Fund ("Fund" and together with all such funds or a group of such funds as the "Funds") only if the Independent Members of the Fund's Board of Trustees (such Independent Members of the Fund's Board together with the other members of the Fund's Board, referred to as the "Trustees") appoint a Senior Officer or retain an Independent Fee Consultant ("IFC") who is to manage the process by which proposed management fees are negotiated. The AOD further stipulates that the Senior Officer or IFC is to prepare a written annual evaluation of the fee negotiation process. On September 14, 2006, the Independent Members of the Funds' Boards retained me as IFC for the Funds. In this capacity, I have prepared the second annual written evaluation of the fee negotiation process. I am successor to the first IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed to the second annual written evaluation until his resignation as IFC in August 2006 to become Director of the Division of Market Regulation at the U.S. Securities and Exchange Commission./2/ A. Role of the Independent Fee Consultant The AOD charges the IFC with "managing the process by which proposed management fees...to be charged the Columbia Fund are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." In this role, the IFC does not replace the Trustees in negotiating management fees with CMA, and the IFC does not substitute his or her judgment for that of the Trustees about the reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a Columbia Fund only if the reasonableness of the proposed management fees is determined by the Board of Trustees...using...an annual independent written evaluation prepared by or under the direction of...the Independent Fee Consultant." B. Elements Involved in Managing the Fee Negotiation Process Managing the fee negotiation process has three elements. One involves reviewing the information provided by CMG to the Trustees for evaluating the proposed management fees and augmenting that information, as necessary, with additional information from CMG or other sources and with further analyses of the information and data. The second element involves reviewing the information and analysis relative to at least the following six factors set forth in the AOD: 1.The nature and quality of CMA's services, including the Fund's performance; 2.Management fees (including any components thereof) charged by other mutual fund companies for like services; 3.Possible economies of scale as the Fund grows larger; 4.Management fees (including any components thereof) charged to institutional and other clients of CMA for like services; 5.Costs to CMA and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; and 6.Profit margins of CMA and its affiliates from supplying such services. 1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds' transfer agent. Before the date of this report, CMA merged into an affiliated entity, Banc of America Capital Management, LLC, which was renamed Columbia Management Advisors, LLC and which carries on the business of CMA. CFD also has been renamed Columbia Management Distributors, Inc. 2I am an independent economic consultant. From August 2005 until August 2006, I provided support to Mr. Sirri as an independent consultant. From 1994 to 2004, I was Chief Economist at the Investment Company Institute. Earlier, I was Section Chief and Assistant Director at the Federal Reserve Board and Professor of Economics at Oklahoma State University. I have no material relationship with Bank of America or CMG, aside from serving as IFC, and I am aware of no material relationship with any of their affiliates. To assist me with the report, I engaged NERA Economic Consulting, an independent consulting firm that has had extensive experience in the mutual fund industry. I also have retained Willkie Farr & Gallagher LLP as counsel to advise me in connection with the report. 57 The final element involves providing the Trustees with a written evaluation of the above factors as they relate to the fee negotiation process. C. Organization of the Annual Evaluation The 2006 annual evaluation focuses on the six factors and contains a section for each factor except that CMA's costs and profits from managing the Funds have been combined into a single section. In each section, the discussion of the factor considers and analyzes the available data and other information as they bear upon the fee negotiation process. If appropriate, the discussion in the section may point out certain aspects of the proposed fees that may warrant particular attention from the Trustees. The discussion also may suggest other data, information, and approaches that the Trustees might consider incorporating into the fee negotiation process in future years. In addition to a discussion of the six factors, the report reviews the status of recommendations made in the 2005 IFC evaluation. The 2006 report also summarizes the findings with regard to the six factors and contains a summary of recommendations for possible enhancements to the process. II. Status of 2005 Recommendations The 2005 IFC evaluation contains recommendations aimed at enhancing the evaluation of proposed management fees by Trustees. The section summarizes those recommendations and includes my assessment of the response to the recommendations. 1. Recommendation: Trustees should consider requesting more analytical work from CMG in the preparation of future 15(c) materials. Status: CMG has provided additional analyses to the Trustees on economies of scale, a comparative analysis of institutional and retail management fees, management fee breakpoints, risk-adjusted performance, fee waivers and expense reimbursements, and CMG's costs and profitability. 2. Recommendation: Trustees may wish to consider whether CMG should continue expanding the use of Morningstar or other third party data to supplement CMG's fee and performance analysis that is now based primarily on Lipper reports. Status: CMG has used data from Morningstar Inc. to compare with data from Lipper Inc. ("Lipper") in performing the Trustees' screening procedures. 3. Recommendation: Trustees should consider whether...the fund-by-fund screen...should place comparable emphasis on both basis point and quintile information in their evaluation of the funds...Also, the Trustees should consider incorporating sequences of one year performance into a fund-by-fund screen. Status: CMG has not provided Trustees with results of the screening process using percentiles. CMG has provided Trustees with information on the changes in performance and expenses between 2005 and 2006 and data on one-year returns. 4. Recommendation: Given the volatility of fund performance, the Trustees may want to consider whether a better method exists than th[e] fee waiver process to deal with fund underperformance. Status: It is my understanding that the Trustees have determined to address fund underperformance not only through fee waivers and expense caps but also through discussions with CMG regarding the sources of underperformance. CMG has provided Trustees with an analysis of the relationship between breakpoints, expense reimbursements, and fee waivers. 5. Recommendation: [Seventy-one] percent of funds [have] yet to reach their first management fee breakpoint... Trustees may wish to consider whether the results of my ongoing economies-of-scale work affects the underlying economic assumptions reflected in the existing breakpoint schedules. Status: CMG has prepared a memo for the Trustees discussing its views on the nature and sharing of potential economies of scale. The memo discuses CMG's view that economies of scale arise at the complex level rather than the fund level. The memo also describes steps, including the introduction of breakpoints, taken to share economies of scale with shareholders. CMG's analysis, however, does not discuss specific sources of economies of scale and does not link breakpoints to economies of scale that might be realized as the Funds' assets increase. 58 6. Recommendation: Trustees should continue working with management to address issues of funds that demonstrate consistent or significant underperformance even if the fee levels for the funds are low. Status: Trustees monitor performance on an ongoing basis. III. Findings A. General 1. Based upon my examination of the available information and the six factors, I conclude that the Trustees have the relevant information necessary to evaluate the reasonableness of the proposed management fees for the Funds. CMG has provided the Trustees with relevant materials on the six factors through the 15(c) contract renewal process and in materials prepared for review at Board and Committee meetings. 2. In my view, the process by which the proposed management fees of the Funds have been negotiated in 2006 thus far has been, to the extent practicable, at arms' length and reasonable and consistent with the AOD. B. Nature and Quality of Services, Including Performance 3. The performance of the Funds has been relatively strong, especially that of fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance periods, over 60 percent of the funds have ranked in the top three performance quintiles. 4. The performance of the equity Funds overall, though less concentrated in the top two quintiles than the fixed income Funds, improved in 2006 relative to that in 2005. The fixed-income funds maintained the relatively high performance level of 2005 in 2006. 5. The Funds' overall performance adjusted for risk was significantly stronger than performance unadjusted for risk. Domestic and international equity funds, in particular, moved to higher relative performance rankings after adjusting for risk. 6. The procedure used to construct the performance universe in which each Fund's performance is ranked relative to comparable funds may bias a Fund's ranking upward within that universe. The bias occurs because the performance ranking procedure includes all share classes of multi-class funds in the universe and because the procedure ranks either no-load or A share classes of the Funds. No-load and A share classes generally have lower total expenses than B and C shares (owing to B and C shares having higher distribution/service fees) and thus, given all else, would outperform many of B and C share classes included in the universe. A preliminary analysis that adjusts for the bias results in a downward movement in the relative performance for the Funds but does not change the general finding that the Funds' performance has been strong relative to comparable funds. C. Management Fees Charged by Other Mutual Fund Companies 7. The Funds' management fees and total expenses are generally low relative to those of their peers. At least 56 percent of the Funds are in the first or second quintiles with the lowest fees and expenses and nearly three fourths or more in the first three quintiles. Equity Funds are more highly concentrated in the first three quintiles than fixed-income Funds. 8. The fee and expense rankings as whole are similar to those in 2005 in that the majority of funds are ranked in the top quintiles. Nonetheless, a number of individual funds experienced a change in ranking between 2005 and 2006. This fund-level instability may reflect sensitivity of rankings to the composition of the comparison groups, as the membership of the peer groups typically changed substantially between the two years. 9. The Liberty Money Market Fund VS appears to have a higher management fee structure than that of other Columbia money market funds of comparable asset size. 59 D. Trustees' Fee and Performance Evaluation Process 10. The Trustees' evaluation process identified 21 funds in 2006 for further review based upon their relative performance or expenses. Seventeen of these funds had been subject to review in 2004 or 2005. E. Potential Economies of Scale 11. CMG has prepared a memo for the Trustees containing its views on the sources and sharing of potential economies of scale. CMG views economies of scale as arising at the complex level and would regard estimates of scale economies for individual funds as unreliable. CMG has not, however, identified specific sources of economies of scale nor has it provided any estimates of the magnitude of any economies of scale. In the memo, CMG also describes measures taken by the Trustees and CMG that seek to share any potential economies of scale through breakpoints in management fee schedules, expense reimbursements, fee waivers, enhanced shareholder services, fund mergers, and operational consolidation. These measures, although of significant benefit to shareholders, have not been directly linked in the memo to the existence, sources, and magnitude of economies of scale. F. Management Fees Charged to Institutional Clients 12. CMG has provided Trustees with comparisons of mutual fund management fees and institutional fees based upon standardized fee schedules and upon actual fees. Based upon the information, institutional fees are generally lower than the Funds' management fees. This pattern is consistent with the economics of the two financial products. Data are not available, however, on actual institutional fees at other money managers. Thus, it is not possible to determine the extent to which differences between the Funds' management fees and institutional fees are consistent with those seen generally in the marketplace. G. Revenues, Expenses, and Profits 13. The financial statements and the methodology underlying their construction generally form a sufficient basis for Trustees to evaluate the expenses and profitability of the Funds. IV. Recommendations A. Performance 1. Trustees may wish to consider incorporating risk adjusted measures in their evaluation of performance. CMG has begun to prepare reports for the Trustees with risk adjustments, which could form the basis for formally including the measures in the 15(c) materials. To this end, Trustees may wish to have CMG prepare documents explaining risk adjustments and describing their advantages and disadvantages. 2. Trustees may wish to consider having CMG evaluate the sensitivity of performance rankings to the design of the universe. The preliminary analysis contained in the evaluation suggests that the method employed by Lipper, the source of performance rankings used by the Trustees, may bias performance rankings upward. B. Economies of Scale 3. Trustees may wish to consider having CMG extend its analysis of economies of scale by examining the sources of such economies, if any. Identification of the sources may enable the Trustees and CMG to gauge their magnitude. It also may enable the Trustees and CMG to build upon past work on standardized fee schedules so that the schedules themselves are consistent with any economies of scale and their sources. Finally, an extension of the analysis may enable the Trustees and CMG to develop a framework that coordinates the use of fee waivers and expense caps with the standard fee schedules and with any economies of scale and their sources. C. Institutional Fees 4. Trustees may wish to consider encouraging CMG to build further upon its expanded analysis of institutional fees by refining the matching of institutional accounts with mutual funds, by dating the establishment of each institutional account, and by incorporating other accounts, such as subadvisory relationships, trusts, offshore funds, and separately managed accounts into the analysis. 60 D. Profitability 5. Trustees may wish to consider requesting that CMG expand the reporting of revenues and expenses to include more line-item detail for management and administration, transfer agency, fund accounting, and distribution. 6. Trustees may wish to consider requesting that CMG provide a statement of its operations in the 15(c) materials. 7. Trustees may wish to consider the treatment of the revenue sharing with the Private Bank of Bank of America in their review of CMG's profitability. Respectfully submitted, John D. Rea 61 Appendix Sources of Information Used in the Evaluation The following list generally describes the sources and types of information that were used in preparing this report. 1. Performance, management fees, and expense ratios for the Funds and comparable funds from other fund complexes from Lipper and CMG. The sources of this information were CMG and Lipper; 2. CMG's expenses and profitability obtained directly from CMG; 3. Information on CMG's organizational structure; 4. Profitability of publicly traded asset managers from Lipper; 5. Interviews with CMG staff, including members of senior management, legal staff, heads of affiliates, portfolio managers, and financial personnel; 6. Documents prepared by CMG for Section 15(c) contract renewals in 2005 and 2006; 7. Academic research papers, industry publications, professional materials on mutual fund operations and profitability, and SEC releases and studies of mutual fund expenses 8. Interviews with and documents prepared by Ernst & Young LLP in its review of the Private Bank Revenue Sharing Agreement; 9. Discussions with Trustees and attendance at Board and committee meetings during which matters pertaining to the evaluation were considered. In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data management and analysis. NERA has extensive experience in the mutual fund industry that provides unique insights and special knowledge pertaining to my independent analysis of fees, performance, and profitability. I have also retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher LLP as outside counsel to advise me in connection with my evaluation. Finally, meetings and discussions with CMG staff were informative. My participation in Board and committee meetings in which Trustees and CMG management discussed issues relating to management contracts were of great benefit to the preparation of the evaluation. 62 Columbia Funds - Columbia Intermediate Bond Fund ----------------------------------------------------------------- Growth Funds Columbia Acorn Fund Columbia Acorn Select Columbia Acorn USA Columbia Large Cap Growth Fund Columbia Marsico 21st Century Fund Columbia Marsico Focused Equities Fund Columbia Marsico Growth Fund Columbia Mid Cap Growth Fund Columbia Small Cap Growth Fund I Columbia Small Cap Growth Fund II ----------------------------------------------------------------- Core Funds Columbia Common Stock Fund Columbia Large Cap Core Fund Columbia Small Cap Core Fund ----------------------------------------------------------------- Value Funds Columbia Disciplined Value Fund Columbia Dividend Income Fund Columbia Large Cap Value Fund Columbia Mid Cap Value Fund Columbia Small Cap Value Fund I Columbia Small Cap Value Fund II Columbia Strategic Investor Fund ----------------------------------------------------------------- Asset Allocation/Hybrid Columbia Asset Allocation Fund Funds Columbia Asset Allocation Fund II Columbia Balanced Fund Columbia Liberty Fund Columbia LifeGoal/TM/ Balanced Growth Portfolio Columbia LifeGoal/TM/ Growth Portfolio Columbia LifeGoal/TM/ Income Portfolio Columbia LifeGoal/TM/ Income and Growth Portfolio Columbia Masters Global Equity Portfolio Columbia Masters Heritage Portfolio Columbia Masters International Equity Portfolio Columbia Thermostat Fund ----------------------------------------------------------------- Index Funds Columbia Large Cap Enhanced Core Fund Columbia Large Cap Index Fund Columbia Mid Cap Index Fund Columbia Small Cap Index Fund ----------------------------------------------------------------- Specialty Funds Columbia Convertible Securities Fund Columbia Real Estate Equity Fund Columbia Technology Fund ----------------------------------------------------------------- Global/International Funds Columbia Acorn International Columbia Acorn International Select Columbia Global Value Fund Columbia Greater China Fund Columbia International Stock Fund Columbia International Value Fund Columbia Marsico International Opportunities Fund Columbia Multi-Advisor International Equity Fund Columbia World Equity Fund 63 Columbia Funds (continued) - Columbia Intermediate Bond Fund ------------------------------------------------------------ Taxable Bond Funds Columbia Conservative High Yield Fund Columbia Core Bond Fund Columbia Federal Securities Fund Columbia High Income Fund Columbia High Yield Opportunity Fund Columbia Income Fund Columbia Intermediate Bond Fund Columbia Short Term Bond Fund Columbia Strategic Income Fund Columbia Total Return Bond Fund Columbia U.S. Treasury Index Fund ------------------------------------------------------------ Tax-Exempt Bond Funds Columbia California Tax-Exempt Fund Columbia California Intermediate Municipal Bond Fund Columbia Connecticut Tax-Exempt Fund Columbia Connecticut Intermediate Municipal Bond Fund Columbia Georgia Intermediate Municipal Bond Fund Columbia High Yield Municipal Fund Columbia Intermediate Municipal Bond Fund Columbia Massachusetts Intermediate Municipal Bond Fund Columbia Massachusetts Tax-Exempt Fund Columbia Maryland Intermediate Municipal Bond Fund Columbia North Carolina Intermediate Municipal Bond Fund Columbia New York Tax-Exempt Fund Columbia New Jersey Intermediate Municipal Bond Fund Columbia New York Intermediate Municipal Bond Fund Columbia Oregon Intermediate Municipal Bond Fund Columbia Rhode Island Intermediate Municipal Bond Fund Columbia South Carolina Intermediate Municipal Bond Fund Columbia Short Term Municipal Bond Fund Columbia Tax-Exempt Fund Columbia Virginia Intermediate Municipal Bond Fund ------------------------------------------------------------ Money Market Funds Columbia California Tax-Exempt Reserves Columbia Cash Reserves Columbia Connecticut Municipal Reserves Columbia Government Plus Reserves Columbia Government Reserves Columbia Massachusetts Municipal Reserves Columbia Money Market Reserves Columbia Municipal Reserves Columbia New York Tax-Exempt Reserves Columbia Prime Reserves Columbia Tax-Exempt Reserves Columbia Treasury Reserves For complete product information on any Columbia Fund, visit our website at www.columbiafunds.com. 64 Important Information About This Report Columbia Intermediate Bond Fund Transfer Agent Columbia Management Services, Inc.

Wilson President, Columbia Funds Dear Shareholder: Investing is a long-term process and we are pleased that you have chosen to include the Columbia family of funds in your overall financial plan. Your financial advisor can help you establish an appropriate investment portfolio and periodically review that portfolio. A well balanced portfolio is one of the keys to successful long-term investing. Your portfolio should be diversified across different asset classes and market segments and your chosen asset allocation should be appropriate for your investment goals, risk tolerance and time horizons. However, creating an investment strategy is not a one-step process. From time to time, you'll need to re-evaluate your strategy to determine whether your investment needs have changed. Most experts recommend giving your portfolio a "check-up" every year. As you begin your portfolio check-up, consider whether you have experienced any major life events since the last time you assessed your portfolio. You may need to tweak your strategy if you have: . Gotten married or divorced . Added a child to your family . Made a significant change in employment . Entered or moved significantly closer to retirement . Experienced a serious illness or death in the family . Taken on or paid off substantial debt It's important to remember that over time, performance in different market segments will fluctuate. These shifts can cause your portfolio balance to drift away from your chosen asset allocation. A periodic portfolio check-up can help make sure your portfolio stays on track. Remember that asset allocation does not ensure a profit or guarantee against loss. You'll also want to analyze the individual investments in your portfolio. Of course, performance should be a key factor in your analysis, but it's not the only factor to consider. Make sure the investments in your portfolio line up with your overall objectives and risk tolerance. Be aware of changes in portfolio management and pay special attention to any funds that have made significant shifts in their investment strategy. We hope this information will help you, in working with your financial advisor, to stay on track to reach your investment goals. Thank you for your business and for your continued confidence in Columbia Funds. Sincerely, /s/ Christopher L. Wilson Christopher L. Wilson President, Columbia Funds Economic Update - Columbia U.S. Treasury Index Fund Summary For the 12-month period ended March 31, 2007 . Investment-grade bonds rebounded as yields declined, lifting the Lehman Brothers U.S. Aggregate Bond Index to a respectable return. High-yield bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led the US fixed-income markets. Lehman Merrill Lynch Index Index [GRAPHIC] [GRAPHIC] 6.59% 11.45% . The broad US stock market, as measured by the S&P 500 Index, returned 11.83%. Stock markets outside the United States were even stronger, as measured by the MSCI EAFE Index. S&P Index MSCI Index [GRAPHIC] [GRAPHIC] 11.83% 20.20% The Lehman Brothers U.S. 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, and 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 U.S. High Yield, Cash Pay Index tracks the performance of non-investment-grade corporate bonds. The S&P 500 Index tracks the performance of 500 widely held, large-capitalization US stocks. The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. 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. US economic growth advanced at a modest pace during the 12-month period that began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on the economy throughout the period, with few signs that relief was imminent. Energy prices trended downward, but rose again late in the period, and core inflation moved higher. Yet, many economic indicators remained positive. Job growth, for example, was relatively strong, as the labor markets added an average of 164,000 new jobs each month over the period and the unemployment rate declined to 4.4%. Personal income rose and consumer spending continued to expand, albeit at a slower pace as the period wore on. Against this backdrop, economic growth averaged around 2.2% for the 12-month period. Between April and June 2006, the Federal Reserve Board (the Fed) raised a key short-term interest rate, the federal funds rate, twice -- to 5.25%. But after its June meeting, the Fed turned cautious in the face of slower economic growth and held the federal funds rate steady. Investors reacted favorably to the prospect of stable or lower interest rates and fueled a rally that moved stock prices higher and gave a boost to the bond market as well. Bonds bounced back Although bond yields moved higher early in the period, most segments of the US bond market delivered respectable returns, as prices rose and yields declined in reaction to the Fed's mid-year decision to put further short-term rate increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether for the bond market, ended the 12-month period at 4.63% -- somewhat lower than where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond Index returned 6.59%. High-yield bonds led the US fixed-income markets, reflecting investor confidence about the overall resilience of the economy despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay Index returned 11.45%. Despite late set-back, stocks moved solidly higher Stock prices rose at an above-average pace during the 12-month period covered by this report. The S&P 500 Index, a broad measure of common stock performance, rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap stocks, as measured by their respective Russell indices. Foreign stock markets were even stronger than the US market. The MSCI EAFE Index, which tracks stock market performance in industrialized countries outside the United States and Canada returned 20.20%, despite a volatile stretch late in the period when the US and many foreign stock markets retreated in response to a sharp decline in the Chinese market and other market-specific factors. /1/10-year Treasury note used solely as a benchmark for long-term interest rates.

The Citigroup Bond U.S. Treasury Index is an index composed of all US Treasury notes and bonds with remaining maturities of at least one year and outstanding principal of at least $25 million that are included in the Citigroup Broad Investment-Grade Bond Index. Securities in the Citigroup Bond U.S. Treasury Index are weighted by market value, that is, the price per bond or note multiplied by the number of bonds or notes outstanding. 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. Performance results reflect any waivers or reimbursements of fund expenses by the investment advisor and/or any of its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. All results shown assume reinvestment of distributions. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. 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 requirements may vary. Please see the fund's prospectus for details. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares The returns of Class A, Class B and Class C shares include returns of the fund's Class Z shares (the oldest existing fund share class) for periods prior to the inception of Class A, Class B and Class C shares, respectively. These returns have not been restated to reflect any expense differential (e.g. Rule 12b-1 fees) between Class Z shares and Class A, Class B or Class C shares. If differences in expenses had been reflected, the returns shown for Class A, Class B and Class C shares for periods prior to the inception of Class A, Class B and Class C shares, respectively, would have been lower. Class A, Class B and Class C shares were initially offered on November 25, 2002 and Class Z shares were initially offered on June 4, 1991. 2 Understanding Your Expenses - Columbia U.S. Treasury Index Fund 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. 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 fees, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand the ongoing costs of investing in the fund and to compare these costs with the ongoing 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 $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and is calculated based on the fund's actual operating expenses. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. Compare with other funds Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing cost of investing in a fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. 10/01/06 - 03/31/07 Account value at the Account value at the Expenses paid Fund's annualized beginning of the period ($) end of the period ($) during the period ($) expense ratio (%) - ------------------------------------------------------------------------------------------------- Actual Hypothetical Actual Hypothetical Actual Hypothetical Actual Class A 1,000.00 1,000.00 1,019.90 1,021.94 3.02 3.02 0.60 Class B 1,000.00 1,000.00 1,016.11 1,018.20 6.79 6.79 1.35 Class C 1,000.00 1,000.00 1,016.80 1,018.95 6.03 6.04 1.20 Class Z 1,000.00 1,000.00 1,020.89 1,022.99 1.96 1.97 0.39 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 investment advisor and/or any of its affiliates not waived or reimbursed a portion of expenses, account value at the end of the period would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund and do not reflect any transaction costs, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical examples provided may not help you determine the relative total costs of owning shares of different funds. If these transaction costs were included, your costs would have been higher. 3 Portfolio Manager's Report - Columbia U.S. Treasury Index Fund Performance data quoted represents past performance and current performance may be lower or higher.

For the 12-month period that ended March 31, 2007, Columbia U.S. Treasury Index Fund's Class A shares returned 5.30% without sales charge. The fund's Class Z shares returned 5.53%. The fund's benchmark, the Citigroup Bond U.S. Treasury Index, posted a total return of 5.85% over the same period./1/ Fees generally accounted for the difference between the fund's return and that of the index. The fund incurs expenses while the index does not. The fund's return was slightly lower than the average return of its peer group, the Lipper General U.S. Treasury Funds Category, which was 5.69%./2/ A steady Fed helped raise Treasury bond prices Treasury bond prices moved slightly higher for the 12-month period, but not in a straight line. During the first three months of the reporting period, the bond market retreated sharply as fixed-income investors began to fear that the Federal Reserve Board (the Fed) was prepared to continue to raise short-term interest rates. However, when the Fed held the line on additional rate hikes at its June 2006 meeting, bond prices moved higher before settling into a fairly narrow trading range for the remainder of the period. Flight to quality late in the period For most of the 12-month reporting period, investors were rewarded for taking on credit risk. Investment-grade corporate bonds outperformed comparable Treasury securities by nearly a full percentage point. However, this trend reversed itself during the first quarter of 2007, when the credit scares experienced by the subprime mortgage market created a flight-to-quality mindset that enabled Treasuries to keep pace with corporates. Yields declined as prices rose During the year, the average yield to maturity on the fund declined from 4.9% to 4.7%, consistent with a slight decline in interest rates across most maturity ranges. The fund's average maturity also declined from 7.1 years to 6.9 years because we reduced the fund's holdings in the 10+ year maturity range by approximately five percentage points and made a corresponding increase in the one-to-five-year range. At the end of the period, bond yields were essentially flat across the maturity spectrum, with 30-year securities yielding only a quarter of a percentage point more than two-year securities. We believe this yield pattern suggests that the market is anticipating a slight decrease in short-term rates by the end of the year. While an unexpectedly weak economy could, in theory, force the Fed to lower rates more aggressively, we believe short rates and the overall bond market will be fairly stable in the year ahead. /1/The Citigroup Bond U.S. Treasury Index is an index composed of all US Treasury notes and bonds with remaining maturities of at least one year and outstanding principal of at least $25 million that are included in the Citigroup Broad Investment-Grade Bond Index.

Portfolio Management David Lindsay has managed the Columbia U.S. Treasury Index Fund since July 1994 and has been with the advisor or its predecessors or affiliate organizations since 1986. Portfolio holdings and characteristics are subject to change and may not be representative of current holdings and characteristics. The outlook for this fund may differ from that presented for other Columbia Funds. Performance for different classes of shares will vary based on differences in sales charges and fees associated with each class. For standardized performance, please refer to the Performance Information page. The value of the fund may be affected by interest rate changes and the creditworthiness of issuers held in the fund. When interest rates go up, bond prices typically drop, and vice versa. The fund is subject to indexing risk; Your investment in the fund will typically decline in value when its index declines. Since the fund is designed to track its index, the fund cannot purchase other securities that may help offset declines in its index. In addition, because the fund may not hold all issues included in its index, may not always be fully invested, and bears transaction costs and expenses, the fund's performance may fail to match the performance of its index, after taking expenses into account. Security prices in a market, sector or industry may fall, reducing the value of your investment. Fund shares are not guaranteed or backed by the US government or any agency. 5 Investment Portfolio - Columbia U.S. Treasury Index Fund March 31, 2007 Government & Agency Obligations - 98.0% Par ($) Value ($) U.S. Treasury Bonds - 27.7% 12.000% 08/15/13 (a) 3,175,000 3,477,492 7.500% 11/15/16 (a) 6,150,000 7,473,929 8.750% 05/15/17 (a) 1,330,000 1,758,197 7.875% 02/15/21 (a) 6,000,000 7,794,372 8.125% 08/15/21 (a) 950,000 1,264,242 7.250% 08/15/22 (a) 2,350,000 2,939,152 6.875% 08/15/25 (a) 3,600,000 4,439,811 6.125% 11/15/27 (a) 5,450,000 6,292,194 5.250% 02/15/29 (a) 2,750,000 2,870,956 4.500% 02/15/36 (a) 2,150,000 2,027,046 ----------------------------------------------- ---------- ----------- U.S. Treasury Bonds Total 40,337,391 U.S. Treasury Notes - 70.3% 4.875% 04/30/08 (a) 4,000,000 3,999,532 5.625% 05/15/08 4,815,000 4,854,310 4.125% 08/15/08 (a) 4,400,000 4,362,873 3.125% 10/15/08 (a) 13,300,000 12,987,756 4.625% 11/30/08 (a) 2,950,000 2,947,926 2.625% 03/15/09 (a) 3,650,000 3,517,403 5.500% 05/15/09 5,650,000 5,753,067 4.875% 08/15/09 (a) 9,450,000 9,511,274 4.000% 04/15/10 (a) 3,800,000 3,741,814 5.750% 08/15/10 (a) 9,750,000 10,117,526 5.000% 08/15/11 (a) 13,850,000 14,118,344 4.000% 11/15/12 (a) 2,450,000 2,385,688 3.875% 02/15/13 (a) 8,250,000 7,968,658 4.250% 08/15/14 (a) 5,000,000 4,887,695 4.000% 02/15/15 (a) 3,550,000 3,403,286 4.125% 05/15/15 (a) 400,000 386,312 4.500% 02/15/16 (a) 7,700,000 7,621,799 ----------------------------------------------- ---------- ----------- U.S. Treasury Notes Total 102,565,263 ----------------------------------------------- ---------- ----------- Total Government & Agency Obligations (cost of $141,790,683) 142,902,654 Shares Securities Lending Collateral - 28.5% State Street Navigator Securities Lending Prime Portfolio (b) 41,524,419 41,524,419 ----------------------------------------------- ---------- ----------- Total Securities Lending Collateral (cost of $41,524,419) 41,524,419 See Accompanying Notes to Financial Statements. 6 Columbia U.S. Treasury Index Fund March 31, 2007 Par ($) Value ($) Short-Term Obligation - 0.8% Repurchase agreement with Fixed Income Clearing Corp., dated 03/30/07, due 04/02/07 at 5.060%, collateralized by a U.S. Agency Obligation maturing 02/15/19, market value of $1,241,082 (repurchase proceeds $1,213,511) 1,213,000 1,213,000 ---------------------------------------------------- --------- ----------- Total Short-Term Obligation (cost of $1,213,000) 1,213,000 ---------------------------------------------------- --------- ----------- Total Investments - 127.3% (cost of $184,528,102)(c) 185,640,073 ---------------------------------------------------- --------- ----------- Other Assets & Liabilities, Net - (27.3)% (39,811,425) ---------------------------------------------------- --------- ----------- Net Assets - 100.0% 145,828,648 Notes to Investment Portfolio: (a)All or a portion of this security was on loan at March 31, 2007.

Organization Columbia U.S. Treasury Index Fund (the "Fund"), a series of Columbia Funds Series Trust I (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 to provide investment results that, before deduction of operating expenses, match the price and yield performance of the Citigroup Bond U.S. Treasury Index. 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 B shares are subject to a maximum contingent deferred sales charge ("CDSC") of 5.00% based upon the holding period after purchase. Class B shares will convert to Class A shares eight 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 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. 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. In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is evaluating the impact the application of SFAS 157 will have on the Fund's financial statement disclosures. 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 Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy. The Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Columbia is responsible for determining that 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 16 Columbia U.S. Treasury Index Fund March 31, 2007 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. Income Recognition Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Corporate actions and dividend income are 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 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 the ex-date. Dividends from net investment income are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Indemnification In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Fund's organizational documents and by contract, the trustees and officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these representations, warranties and indemnities to be minimal. 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 March 31, 2007, permanent book and tax basis differences resulting primarily from differing treatments for discount accretion/premium amortization on debt securities and market discount reclasses were identified and reclassified among the components of the Fund's net assets as follows: Overdistributed Accumulated Net Investment Net Realized Paid-In Income Loss Capital $760,089 $(760,089) $-- 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 March 31, 2007 and March 31, 2006 was as follows: March 31, March 31, 2007 2006 Distributions paid from: Ordinary Income* $6,451,677 $6,344,379 *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. 17 Columbia U.S. Treasury Index Fund March 31, 2007 As of March 31, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed Undistributed Net Ordinary Long-term Unrealized Income Capital Gains Depreciation* $198,020 $-- $(157,859) *The differences between book-basis and tax-basis net unrealized depreciation are primarily due to deferral of losses from wash sales and differing treatment for discount accretion/premium amortization on debt securities. Unrealized appreciation and depreciation at March 31, 2007, based on cost of investments for federal income tax purposes was: Unrealized appreciation $ 1,724,575 Unrealized depreciation (1,882,434) Net unrealized depreciation $ (157,859) The following capital loss carryforwards, determined as of March 31, 2007, 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 2009 $ 388,326 2013 151,924 2014 790,826 2015 1,853,769 Total $ 3,184,845 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 March 31, 2007, post-October capital losses of $379,673 attributed to security transactions were deferred to April 1, 2007. 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 No. 109 (the "Interpretation"). This Interpretation is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006 and is to be applied to open 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 is evaluating 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, an indirect, wholly-owned subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to the Fund. Columbia receives a monthly investment advisory fee at the annual rate of 0.10% of the Fund's average daily net assets. Administration Fee Columbia provides administrative services to the Fund pursuant to an administrative services agreement. Columbia, from the administration fee it receives from the Fund, pays all expenses of the Fund, except the fees and expenses of the Trustees who are not interested persons, service and distribution fees, brokerage fees and commissions, annual sub-account fees payable with respect to shares of the Fund held by defined contribution plans, interest on borrowings, taxes and such extraordinary, non-recurring expenses as may arise, including litigation expenses. Columbia receives a monthly administration fee for its services as administrator at the annual rate of 0.30% of the average daily net assets of the Fund. Underwriting Discounts, Service and Distribution Fees Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal underwriter of the Fund. For the year ended March 31, 2007, the Distributor has retained net underwriting discounts $5,992 on sales of the Fund's Class A shares and net CDSC fees of $0, $5,923 and $0 on Class A, Class B and Class C share redemptions, respectively. 18 Columbia U.S. Treasury Index Fund March 31, 2007 The Fund has adopted a Rule 12b-1 plan (the "Plan"), which allows the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Fund. The Plan also requires the payment of a monthly distribution fee to the Distributor equal to 0.75% annually 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 12b-1 fees for Class C shares of the Fund so that these fees do not exceed 0.85% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time. 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. Sub-Account Services Fee The Trust may enter into agreements with one or more entities, including affiliates of Columbia, pursuant to which such entities agree to perform certain sub-account and administrative functions ("Sub-Account Services") for a fee of $21.00 per-account with respect to Class Z shares of the Fund held by defined contribution plans. Such entities are compensated by the Fund for the Sub-Account Services. For the year ended March 31, 2007, the Administrator reimbursed the Fund for sub-account service fees in the amount of $13,333 for the Fund. Fee Waivers Columbia has voluntarily agreed to waive fees and reimburse the Fund for certain expenses to the extent that total expenses (exclusive of distribution and service fees, sub account service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) exceed the annual rate of 0.35% of the Fund's average daily net assets. Columbia, at its discretion, may revise or discontinue this arrangement at any time. Fees Paid to Officers and Trustees All officers of the Fund are employees of Columbia or its affiliates and, with the exception of the Fund's Chief Compliance Officer, receive no compensation from the Fund. The Board of Trustees has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund, along with other affiliated funds, pays its pro-rata share of the expenses associated with the Chief Compliance Officer. The Fund's expenses for the Chief Compliance Officer will not exceed $15,000 per year. The Fund's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Fund's assets. Other Columbia provides certain services to the Fund related to the requirements of the Sarbanes-Oxley Act of 2002. The fees for such services are included as part of the administration fee. Note 5. Portfolio Information For the year ended March 31, 2007, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $54,715,213 and $53,371,320 respectively, all of which were U.S. Government securities. Note 6. Line of Credit The Trust and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured line of credit, both provided by State Street. Borrowings are available for temporary or emergency purposes. Interest on the committed line of credit is charged to each participating fund based on the fund's 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 committed line of credit. Interest on the uncommitted line of credit is charged to each participating fund based on the fund's borrowings at a variable rate per annum equal to the Federal Funds Rate plus a spread, as determined and quoted by State Street at the time of the request for a loan. A one-time structuring fee of $30,000 is also accrued and apportioned to each fund participating in the uncommitted line of credit based on the average net assets of the participating funds. In addition, if the uncommitted line of credit is extended for an additional period, an annual administration fee of $15,000 will be charged and apportioned among the participating fund. The commitment fee and structuring fee are included in "Other expenses" in the Statement of Operations. 19 Columbia U.S. Treasury Index Fund March 31, 2007 For the year ended March 31, 2007, the average daily loan balance outstanding on days where borrowing existed was $1,000,000 at a weighted average interest rate of 5.60% Note 7. Shares of Beneficial Interest As of March 31, 2007, one shareholder held 32.4% of the shares outstanding. The shares were beneficially owned by participant accounts over which BOA and/or its affiliates had either sole or joint investment discretion. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund. Note 8. Securities Lending The Fund commenced a securities lending program in August 2006 and may lend its securities to certain approved brokers, dealers and other financial institutions. Each loan is collateralized by cash, in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The collateral received is invested and the income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, is paid to the Fund. Generally, in the event of borrower default, the Fund has the right to use the collateral to offset any losses incurred. In the event the Fund is delayed or prevented from exercising its right to dispose of the collateral, there may be a potential loss to the Fund. The Fund bears the risk of loss with respect to the investment of collateral. Note 9. Disclosure of Significant Risks and Contingencies 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") on matters relating to mutual fund trading. The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". 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 that was developed by an independent distribution consultant and approved by the SEC on April 6, 2007. 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 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 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 20 Columbia U.S. Treasury Index Fund March 31, 2007 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. 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 were not dismissed. On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that certain conduct, including market timing, entitled Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was removed to federal court in Massachusetts and the federal Judicial Panel 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 settlement is subject to court approval. In 2004, the Columbia Funds' adviser and distributor and certain affiliated entities and individuals 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. Certain Columbia Funds were named as nominal defendants. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment in favor of the defendants. The plaintiffs appealed to the United States Court of Appeals for the First Circuit on December 30, 2005. A stipulation and settlement agreement dated January 19, 2007 was filed in the First Circuit on February 14, 2007, with a joint stipulation of dismissal and motion for remand to obtain district court approval of the settlement. That joint motion was granted and the appeal was dismissed. On March 6, 2007, the case was remanded to the District Court. On May 11, 2007, the District Court entered a preliminary approval order which granted preliminary approval of the settlement. A final settlement hearing, at which the District Court will determine whether the proposed settlement should be finally approved and the action dismissed on the merits with prejudice, is scheduled for September 18, 2007. The terms of the settlement, if finally approved, will require payments by the funds' adviser and/or its affiliates, including payment of plaintiffs' attorneys' fees and notice to class members. In the event that the settlement is not finally approved, the plaintiffs may elect to go forward with their appeal and no opinion is expressed regarding the likely outcome or financial impact of such an appeal on any fund. 21 Report Of Independent Registered Public Accounting Firm To the Trustees of Columbia Funds Series Trust I and the Shareholders of Columbia U.S. Treasury Index 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 U.S. Treasury Index Fund (the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2007 by correspondence with the custodian, provide a reasonable basis for our opinion.

Vallan (Born 1969) - -------------------------------------------------------------------------------------------- One Financial Center Vice President-Fund Treasury of the Advisor since Boston, MA 02111 October, 2004; Vice President-Trustee Reporting of the Controller (since 2006) Advisor from April, 2002 to October, 2004; Management Consultant, PricewaterhouseCoopers (independent registered public accounting firm) prior to October, 2002. 27 Board Consideration and Approval of Investment Advisory Agreements The Advisory Fees and Expenses Committee of the Board of Trustees meets one or more times annually to review the advisory agreements (collectively, the "Agreements") of the funds for which the Trustees serve as trustees (each a "fund") and determine whether to recommend that the full Board approve the continuation of the Agreements for an additional one-year period. After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements. In addition, the Board, including the Independent Trustees, considers matters bearing on the Agreements at most of its other meetings throughout the year and meets regularly with the heads of each investment area within Columbia. Through the Board's Investment Oversight Committees, Trustees also meet with selected fund portfolio managers at various times throughout the year. The Trustees receive and review all materials that they, their legal counsel or Columbia, the funds' investment adviser, believe to be reasonably necessary for the Trustees to evaluate the Agreements and determine whether to approve the continuation of the Agreements. Those materials generally include, among other items, (i) information on the investment performance of each fund relative to the performance of peer groups of mutual funds and the fund's performance benchmarks, (ii) information on each fund's advisory fees and other expenses, including information comparing the fund's expenses to those of peer groups of mutual funds and information about any applicable expense caps and fee "breakpoints," (iii) information about the profitability of the Agreements to Columbia, including potential "fall-out" or ancillary benefits that Columbia and its affiliates may receive as a result of their relationships with the funds and (iv) information obtained through Columbia's response to a questionnaire prepared at the request of the Trustees by counsel to the funds and independent legal counsel to the Independent Trustees. The Trustees also consider other information such as (v) Columbia's financial results and financial condition, (vi) each fund's investment objective and strategies and the size, education and experience of Columbia's investment staffs and their use of technology, external research and trading cost measurement tools, (vii) the allocation of the funds' brokerage, if any, and the use of "soft" commission dollars to pay for research products and services, (viii) Columbia's resources devoted to, and its record of compliance with, the funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (ix) Columbia's response to various legal and regulatory proceedings since 2003 and (x) the economic outlook generally and for the mutual fund industry in particular. In addition, the Advisory Fees and Expenses Committee confers with the funds' independent fee consultant and reviews materials relating to the funds' relationships with Columbia provided by the independent fee consultant. Throughout the process, the Trustees have the opportunity to ask questions of and request additional materials from Columbia and to consult with independent legal counsel to the Independent Trustees and the independent fee consultant. The Board of Trustees most recently approved the continuation of the Agreements at its October, 2006 meeting, following meetings of the Advisory Fees and Expenses Committee held in August, September and October, 2006. In considering whether to approve the continuation of the Agreements, the Trustees, including the Independent Trustees, did not identify any single factor as determinative, and each weighed various factors as he or she deemed appropriate. The Trustees considered the following matters in connection with their approval of the continuation of the Agreements: The nature, extent and quality of the services provided to the funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by Columbia and its affiliates to the funds and the resources dedicated to the funds by Columbia and its affiliates. Among other things, the Trustees considered (i) Columbia's ability (including its personnel and other resources, compensation programs for personnel involved in fund management, reputation and other attributes) to attract and retain highly qualified research, advisory and supervisory investment professionals; (ii) the portfolio management services provided by those investment professionals; and (iii) the trade execution services provided on behalf of the funds. For each fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the continuation of the Agreements. 28 Investment performance of the funds and Columbia. The Trustees reviewed information about the performance of each fund over various time periods, including information prepared by an independent third party that compared the performance of each fund to the performance of peer groups of mutual funds and performance benchmarks. The Trustees also reviewed a description of the third party's methodology for identifying each fund's peer group for purposes of performance and expense comparisons. The Trustees also considered additional information that the Advisory Fees and Expenses Committee requested from Columbia relating to funds that presented relatively weaker performance and/or relatively higher expenses. In the case of each fund whose performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Trustees concluded that other factors relevant to performance were sufficient, in light of other considerations, to warrant continuation of the fund's Agreements. Those factors varied from fund to fund, but included one or more of the following: (i) that the fund's performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the fund's investment strategy and policies and that the fund was performing as expected, given these investment decisions, market conditions and the fund's investment strategy; (iii) that the fund's performance was competitive when compared to other relevant performance benchmarks or peer groups; (iv) that Columbia had taken or was taking steps designed to help improve the fund's investment performance, including, but not limited to, replacing portfolio managers or modifying investment strategies; and (v) that the fund was proposed to be reorganized into another fund, and that such reorganization would result in a reduction in fund expenses. The Trustees also considered Columbia's performance and reputation generally, the funds' performance as a fund family generally, and Columbia's historical responsiveness to Trustee concerns about performance and Columbia's willingness to take steps intended to improve performance. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of each fund and Columbia was sufficient, in light of other considerations, to warrant the continuation of the Agreement(s) pertaining to that fund. The costs of the services provided and profits realized by Columbia and its affiliates from their relationships with the funds. The Trustees considered the fees charged to the funds for advisory services as well as the total expense levels of the funds. That information included comparisons (provided by management and by an independent third party) of each fund's advisory fees and total expense levels to those of the fund's peer groups and information about the advisory fees charged by Columbia to comparable institutional accounts. In considering the fees charged to those accounts, the Trustees took into account, among other things, management's representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for Columbia, and the additional resources required to manage mutual funds effectively. In evaluating each fund's advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the fund. The Trustees considered existing advisory fee breakpoints, and Columbia's use of advisory fee waivers and expense caps, which benefited a number of the funds. The Trustees also noted management's stated justification for the fees charged to the funds, which included information about the investment performance of the funds and the services provided to the funds. The Trustees also considered the compensation directly or indirectly received by Columbia and its affiliates from their relationships with the funds. The Trustees reviewed information provided by management as to the profitability to Columbia and its affiliates of their relationships with each fund, and information about the allocation of expenses used to calculate profitability. When reviewing profitability, the Trustees also considered court cases in which adviser profitability was an issue in whole or in part, the performance of the relevant funds, the expense level of each fund, and whether Columbia had implemented breakpoints and/or expense caps with respect to the fund. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each fund, and the related profitability to Columbia and its affiliates of their relationships with the fund, supported the continuation of the Agreement(s) pertaining to that fund. 29 Economies of Scale. The Trustees considered the existence of any economies of scale in the provision by Columbia of services to each fund, to groups of related funds, and to Columbia's investment advisory clients as a whole and whether those economies were shared with the funds through breakpoints in the investment advisory fees or other means, such as expense waivers/reductions and additional investments by Columbia in investment, trading and compliance resources. The Trustees noted that many of the funds benefited from breakpoints, expense caps, or both. In considering those issues, the Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to Columbia and its affiliates of their relationships with the funds, as discussed above. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the funds supported the continuation of the Agreements. Other Factors. The Trustees also considered other factors, which included but were not limited to the following: .. the extent to which each fund had operated in accordance with its investment objective and investment restrictions, the nature and scope of the compliance programs of the funds and Columbia and the compliance-related resources that Columbia and its affiliates were providing to the funds; .. the nature, quality, cost and extent of administrative and shareholder services performed by Columbia and its affiliates, both under the Agreements and under separate agreements for the provision of transfer agency and administrative services; .. so-called "fall-out benefits" to Columbia and its affiliates, such as the engagement of its affiliates to provide distribution, brokerage and transfer agency services to the funds, and the benefits of research made available to Columbia by reason of brokerage commissions generated by the funds' securities transactions, as well as possible conflicts of interest associated with those fall-out and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor those possible conflicts of interest; and .. the draft report provided by the funds' independent fee consultant, which included information about and analysis of the funds' fees, expenses and performance. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel and the independent fee consultant, the Trustees, including the Independent Trustees, approved the continuance of each of the Agreements through October 31, 2007. 30 Summary of Management Fee Evaluation by Independent Fee Consultant Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between the Office of Attorney General of New York State and Columbia Management Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006 I. Overview Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors, Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates that CMA may manage or advise a Columbia Fund ("Fund" and together with all such funds or a group of such funds as the "Funds") only if the Independent Members of the Fund's Board of Trustees (such Independent Members of the Fund's Board together with the other members of the Fund's Board, referred to as the "Trustees") appoint a Senior Officer or retain an Independent Fee Consultant ("IFC") who is to manage the process by which proposed management fees are negotiated. The AOD further stipulates that the Senior Officer or IFC is to prepare a written annual evaluation of the fee negotiation process. On September 14, 2006, the Independent Members of the Funds' Boards retained me as IFC for the Funds. In this capacity, I have prepared the second annual written evaluation of the fee negotiation process. I am successor to the first IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed to the second annual written evaluation until his resignation as IFC in August 2006 to become Director of the Division of Market Regulation at the U.S. Securities and Exchange Commission./2/ A. Role of the Independent Fee Consultant The AOD charges the IFC with "managing the process by which proposed management fees...to be charged the Columbia Fund are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." In this role, the IFC does not replace the Trustees in negotiating management fees with CMA, and the IFC does not substitute his or her judgment for that of the Trustees about the reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a Columbia Fund only if the reasonableness of the proposed management fees is determined by the Board of Trustees...using...an annual independent written evaluation prepared by or under the direction of...the Independent Fee Consultant." B. Elements Involved in Managing the Fee Negotiation Process Managing the fee negotiation process has three elements. One involves reviewing the information provided by CMG to the Trustees for evaluating the proposed management fees and augmenting that information, as necessary, with additional information from CMG or other sources and with further analyses of the information and data. The second element involves reviewing the information and analysis relative to at least the following six factors set forth in the AOD: 1.The nature and quality of CMA's services, including the Fund's performance; 2.Management fees (including any components thereof) charged by other mutual fund companies for like services; 3.Possible economies of scale as the Fund grows larger; 4.Management fees (including any components thereof) charged to institutional and other clients of CMA for like services; 5.Costs to CMA and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; and 6.Profit margins of CMA and its affiliates from supplying such services. 1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds' transfer agent. Before the date of this report, CMA merged into an affiliated entity, Banc of America Capital Management, LLC, which was renamed Columbia Management Advisors, LLC and which carries on the business of CMA. CFD also has been renamed Columbia Management Distributors, Inc. 2I am an independent economic consultant. From August 2005 until August 2006, I provided support to Mr. Sirri as an independent consultant. From 1994 to 2004, I was Chief Economist at the Investment Company Institute. Earlier, I was Section Chief and Assistant Director at the Federal Reserve Board and Professor of Economics at Oklahoma State University. I have no material relationship with Bank of America or CMG, aside from serving as IFC, and I am aware of no material relationship with any of their affiliates. To assist me with the report, I engaged NERA Economic Consulting, an independent consulting firm that has had extensive experience in the mutual fund industry. I also have retained Willkie Farr & Gallagher LLP as counsel to advise me in connection with the report. 31 The final element involves providing the Trustees with a written evaluation of the above factors as they relate to the fee negotiation process. C. Organization of the Annual Evaluation The 2006 annual evaluation focuses on the six factors and contains a section for each factor except that CMA's costs and profits from managing the Funds have been combined into a single section. In each section, the discussion of the factor considers and analyzes the available data and other information as they bear upon the fee negotiation process. If appropriate, the discussion in the section may point out certain aspects of the proposed fees that may warrant particular attention from the Trustees. The discussion also may suggest other data, information, and approaches that the Trustees might consider incorporating into the fee negotiation process in future years. In addition to a discussion of the six factors, the report reviews the status of recommendations made in the 2005 IFC evaluation. The 2006 report also summarizes the findings with regard to the six factors and contains a summary of recommendations for possible enhancements to the process. II. Status of 2005 Recommendations The 2005 IFC evaluation contains recommendations aimed at enhancing the evaluation of proposed management fees by Trustees. The section summarizes those recommendations and includes my assessment of the response to the recommendations. 1. Recommendation: Trustees should consider requesting more analytical work from CMG in the preparation of future 15(c) materials. Status: CMG has provided additional analyses to the Trustees on economies of scale, a comparative analysis of institutional and retail management fees, management fee breakpoints, risk-adjusted performance, fee waivers and expense reimbursements, and CMG's costs and profitability. 2. Recommendation: Trustees may wish to consider whether CMG should continue expanding the use of Morningstar or other third party data to supplement CMG's fee and performance analysis that is now based primarily on Lipper reports. Status: CMG has used data from Morningstar Inc. to compare with data from Lipper Inc. ("Lipper") in performing the Trustees' screening procedures. 3. Recommendation: Trustees should consider whether...the fund-by-fund screen...should place comparable emphasis on both basis point and quintile information in their evaluation of the funds...Also, the Trustees should consider incorporating sequences of one year performance into a fund-by-fund screen. Status: CMG has not provided Trustees with results of the screening process using percentiles. CMG has provided Trustees with information on the changes in performance and expenses between 2005 and 2006 and data on one-year returns. 4. Recommendation: Given the volatility of fund performance, the Trustees may want to consider whether a better method exists than th[e] fee waiver process to deal with fund underperformance. Status: It is my understanding that the Trustees have determined to address fund underperformance not only through fee waivers and expense caps but also through discussions with CMG regarding the sources of underperformance. CMG has provided Trustees with an analysis of the relationship between breakpoints, expense reimbursements, and fee waivers. 5. Recommendation: [Seventy-one] percent of funds [have] yet to reach their first management fee breakpoint... Trustees may wish to consider whether the results of my ongoing economies-of-scale work affects the underlying economic assumptions reflected in the existing breakpoint schedules. Status: CMG has prepared a memo for the Trustees discussing its views on the nature and sharing of potential economies of scale. The memo discuses CMG's view that economies of scale arise at the complex level rather than the fund level. The memo also describes steps, including the introduction of breakpoints, taken to share economies of scale with shareholders. CMG's analysis, however, does not discuss specific sources of economies of scale and does not link breakpoints to economies of scale that might be realized as the Funds' assets increase. 32 6. Recommendation: Trustees should continue working with management to address issues of funds that demonstrate consistent or significant underperformance even if the fee levels for the funds are low. Status: Trustees monitor performance on an ongoing basis. III. Findings A. General 1. Based upon my examination of the available information and the six factors, I conclude that the Trustees have the relevant information necessary to evaluate the reasonableness of the proposed management fees for the Funds. CMG has provided the Trustees with relevant materials on the six factors through the 15(c) contract renewal process and in materials prepared for review at Board and Committee meetings. 2. In my view, the process by which the proposed management fees of the Funds have been negotiated in 2006 thus far has been, to the extent practicable, at arms' length and reasonable and consistent with the AOD. B. Nature and Quality of Services, Including Performance 3. The performance of the Funds has been relatively strong, especially that of fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance periods, over 60 percent of the funds have ranked in the top three performance quintiles. 4. The performance of the equity Funds overall, though less concentrated in the top two quintiles than the fixed income Funds, improved in 2006 relative to that in 2005. The fixed-income funds maintained the relatively high performance level of 2005 in 2006. 5. The Funds' overall performance adjusted for risk was significantly stronger than performance unadjusted for risk. Domestic and international equity funds, in particular, moved to higher relative performance rankings after adjusting for risk. 6. The procedure used to construct the performance universe in which each Fund's performance is ranked relative to comparable funds may bias a Fund's ranking upward within that universe. The bias occurs because the performance ranking procedure includes all share classes of multi-class funds in the universe and because the procedure ranks either no-load or A share classes of the Funds. No-load and A share classes generally have lower total expenses than B and C shares (owing to B and C shares having higher distribution/service fees) and thus, given all else, would outperform many of B and C share classes included in the universe. A preliminary analysis that adjusts for the bias results in a downward movement in the relative performance for the Funds but does not change the general finding that the Funds' performance has been strong relative to comparable funds. C. Management Fees Charged by Other Mutual Fund Companies 7. The Funds' management fees and total expenses are generally low relative to those of their peers. At least 56 percent of the Funds are in the first or second quintiles with the lowest fees and expenses and nearly three fourths or more in the first three quintiles. Equity Funds are more highly concentrated in the first three quintiles than fixed-income Funds. 8. The fee and expense rankings as whole are similar to those in 2005 in that the majority of funds are ranked in the top quintiles. Nonetheless, a number of individual funds experienced a change in ranking between 2005 and 2006. This fund-level instability may reflect sensitivity of rankings to the composition of the comparison groups, as the membership of the peer groups typically changed substantially between the two years. 9. The Liberty Money Market Fund VS appears to have a higher management fee structure than that of other Columbia money market funds of comparable asset size. 33 D. Trustees' Fee and Performance Evaluation Process 10. The Trustees' evaluation process identified 21 funds in 2006 for further review based upon their relative performance or expenses. Seventeen of these funds had been subject to review in 2004 or 2005. E. Potential Economies of Scale 11. CMG has prepared a memo for the Trustees containing its views on the sources and sharing of potential economies of scale. CMG views economies of scale as arising at the complex level and would regard estimates of scale economies for individual funds as unreliable. CMG has not, however, identified specific sources of economies of scale nor has it provided any estimates of the magnitude of any economies of scale. In the memo, CMG also describes measures taken by the Trustees and CMG that seek to share any potential economies of scale through breakpoints in management fee schedules, expense reimbursements, fee waivers, enhanced shareholder services, fund mergers, and operational consolidation. These measures, although of significant benefit to shareholders, have not been directly linked in the memo to the existence, sources, and magnitude of economies of scale. F. Management Fees Charged to Institutional Clients 12. CMG has provided Trustees with comparisons of mutual fund management fees and institutional fees based upon standardized fee schedules and upon actual fees. Based upon the information, institutional fees are generally lower than the Funds' management fees. This pattern is consistent with the economics of the two financial products. Data are not available, however, on actual institutional fees at other money managers. Thus, it is not possible to determine the extent to which differences between the Funds' management fees and institutional fees are consistent with those seen generally in the marketplace. G. Revenues, Expenses, and Profits 13. The financial statements and the methodology underlying their construction generally form a sufficient basis for Trustees to evaluate the expenses and profitability of the Funds. IV. Recommendations A. Performance 1. Trustees may wish to consider incorporating risk adjusted measures in their evaluation of performance. CMG has begun to prepare reports for the Trustees with risk adjustments, which could form the basis for formally including the measures in the 15(c) materials. To this end, Trustees may wish to have CMG prepare documents explaining risk adjustments and describing their advantages and disadvantages. 2. Trustees may wish to consider having CMG evaluate the sensitivity of performance rankings to the design of the universe. The preliminary analysis contained in the evaluation suggests that the method employed by Lipper, the source of performance rankings used by the Trustees, may bias performance rankings upward. B. Economies of Scale 3. Trustees may wish to consider having CMG extend its analysis of economies of scale by examining the sources of such economies, if any. Identification of the sources may enable the Trustees and CMG to gauge their magnitude. It also may enable the Trustees and CMG to build upon past work on standardized fee schedules so that the schedules themselves are consistent with any economies of scale and their sources. Finally, an extension of the analysis may enable the Trustees and CMG to develop a framework that coordinates the use of fee waivers and expense caps with the standard fee schedules and with any economies of scale and their sources. C. Institutional Fees 4. Trustees may wish to consider encouraging CMG to build further upon its expanded analysis of institutional fees by refining the matching of institutional accounts with mutual funds, by dating the establishment of each institutional account, and by incorporating other accounts, such as subadvisory relationships, trusts, offshore funds, and separately managed accounts into the analysis. 34 D. Profitability 5. Trustees may wish to consider requesting that CMG expand the reporting of revenues and expenses to include more line-item detail for management and administration, transfer agency, fund accounting, and distribution. 6. Trustees may wish to consider requesting that CMG provide a statement of its operations in the 15(c) materials. 7. Trustees may wish to consider the treatment of the revenue sharing with the Private Bank of Bank of America in their review of CMG's profitability. Respectfully submitted, John D. Rea 35 Appendix Sources of Information Used in the Evaluation The following list generally describes the sources and types of information that were used in preparing this report. 1. Performance, management fees, and expense ratios for the Funds and comparable funds from other fund complexes from Lipper and CMG. The sources of this information were CMG and Lipper; 2. CMG's expenses and profitability obtained directly from CMG; 3. Information on CMG's organizational structure; 4. Profitability of publicly traded asset managers from Lipper; 5. Interviews with CMG staff, including members of senior management, legal staff, heads of affiliates, portfolio managers, and financial personnel; 6. Documents prepared by CMG for Section 15(c) contract renewals in 2005 and 2006; 7. Academic research papers, industry publications, professional materials on mutual fund operations and profitability, and SEC releases and studies of mutual fund expenses 8. Interviews with and documents prepared by Ernst & Young LLP in its review of the Private Bank Revenue Sharing Agreement; 9. Discussions with Trustees and attendance at Board and committee meetings during which matters pertaining to the evaluation were considered. In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data management and analysis. NERA has extensive experience in the mutual fund industry that provides unique insights and special knowledge pertaining to my independent analysis of fees, performance, and profitability. I have also retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher LLP as outside counsel to advise me in connection with my evaluation. Finally, meetings and discussions with CMG staff were informative. My participation in Board and committee meetings in which Trustees and CMG management discussed issues relating to management contracts were of great benefit to the preparation of the evaluation. 36 Important Information About This Report Columbia U.S. Treasury Index Fund Transfer Agent Columbia Management Services, Inc.

(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 March 31, 2007 and March 31, 2006 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 March 31, 2007 and March 31, 2006 are approximately as follows: 2007 2006 $892,900 $411,000 (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.
