President's Message

Dear Shareholders,

Americans were dispirited in the fourth quarter of 2011 by Washington's inability to reach a plan for deficit reduction and Europe's piecemeal attempt to address its own fiscal issues. Yet, there was sufficient good news to encourage risk taking, buoying both stocks and bonds to solid gains.

U.S. economic data surprised on the upside and fears of recession abated. With the bar of expectations set low, investors responded positively to the announcement that the economy had expanded by 1.8% in the third quarter. Consumer confidence improved, even though consumers remain under pressure with no real increase in disposable income and a continued decline in household net worth. Headline inflation—which tracks a broad range of consumer expenditures, including food and energy—declined. Even manufacturing held its ground.

Against this backdrop, the U.S. equity markets logged solid returns. The S&P 500 Index gained 11.82%, moving into positive territory for the year with quarterly advances in all ten sectors. Mid- and small-cap stocks did even better. Value outperformed growth across all market capitalizations. Energy stocks led the market, as the price of oil moved above $100 a barrel in December. Industrials and materials stocks rose, buoyed by improving economic data. The U.S. fixed-income markets logged modest but solid returns. High-yield bonds were the best performers as the economy showed signs of improvement. Emerging market bonds were strong performers, as inflation came under control in key regions. Municipal bonds and Treasuries eked out only modest gains, as investors moved away from quality in favor of riskier assets.

While fourth quarter gains were encouraging, challenges still remain. Columbia Management, however, remains strong and steadfast. Columbia Management is the eighth largest manager of long-term mutual fund assets with $326 billion under management as of December 31, 2011. The past year has been one of considerable change for the organization as we worked diligently to align products, services and resources in the integration of Columbia Management with RiverSource Investments. The strong line-up of talent, resources and capabilities that has resulted is highlighted by the success of our products. As of December 31, 2011, Columbia Management offers 52 funds rated either 4 or 5 stars by Morningstar.*

*All ratings are based on Class Z shares as of 12/31/2011. Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund's independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges/loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.)

The Morningstar Rating^TM is for Class Z shares only; other classes may have different performance characteristics and may have different ratings. ©2012 Morningstar, Inc. All Rights Reserved.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares and 1.00% for Class C shares in the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower.

Performance results reflect any fee waivers or reimbursements of fund expenses by Columbia Management Investment Advisers, LLC and/or any of its affiliates. Absent these fee waivers or expense reimbursement arrangements, performance results would have been lower.

All results shown assume reinvestment of distributions. Class I, Class Y and Class Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class R and Class W shares are sold at net asset value with distribution and /or service (Rule 12b-1) fees. Class I, Class R, Class W, Class Y and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

*The returns shown for periods prior to the share class inception date (including returns since inception, which are since fund inception) include the returns of the fund's oldest share class.

Understanding Your Expenses – Columbia Large Cap Value Fund

As an investor, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing costs, which generally include management fees, distribution and service (Rule 12b-1) fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.

Analyzing your fund's expenses

To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the "Hypothetical" column assumes a 5% annual rate of return before expenses (which is not the Fund's actual return) and then applies the Fund's actual expense ratio for the period to the hypothetical return. 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 the period. See "Compare with other funds" below for details on how to use the hypothetical data.

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 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 costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund's most recent fiscal half year and divided by 366.

Expenses do not include fees and expenses incurred indirectly by the Fund from the underlying funds in which the Fund may invest (also referred to as "acquired funds"), including affiliated and non-affiliated pooled investments vehicles (including mutual funds and exchange traded funds).

Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Effective August 1, 2011, Steve Schroll, Laton Spahr, CFA^® and Paul Stocking assumed portfolio management responsibility for the fund.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –1.94%, without sales charge. This result was behind the 2.18% gain of the fund's benchmark, the Russell 1000^® Value Index. The fund underperformed the index due primarily to stock selection in financials, consumer discretionary, health care and energy, more than offsetting the positive impact of effective stock selection in information technology and consumer staples. Sector allocation overall also detracted from the fund's results but to a more modest degree.

Volatility characterized the market

The U.S. equity markets generated modestly positive returns for the annual period ended February 29, 2012, but such returns mask what was a fiscal year characterized by frequent bouts of dramatic volatility. Such significant volatility was driven primarily by shifting sentiment toward U.S. economic activity and the potential impact of international economies on the U.S. Optimism early in the annual period for a continued economic recovery gave way to deep concerns about deteriorating U.S. economic data, persistent sovereign debt crises in Europe and the possibility of a hard landing for China's economy. During the annual period, the U.S. equity markets also faced several other exogenous challenges, including the Arab spring, the Japanese natural and nuclear disasters and the massive flooding in Thailand. The third quarter of 2011 was particularly challenging, as these factors, along with political paralysis in Washington D.C. and an unprecedented downgrade of U.S. sovereign debt by Standard & Poor's, caused investor risk aversion to heighten such that the U.S. equity markets experienced their worst quarter since the fourth quarter of 2008. From October through February, U.S. equities rebounded rather strongly, albeit not steadily, as macro concerns began to fade. U.S. economic data in the important labor, housing and manufacturing markets came in better than anticipated, and European authorities made it clear that every effort would be made to ensure that the worst case default scenario would not materialize.

While the fiscal year was bookended by rallies in the U.S. equity markets, a flight to quality still dominated the annual period overall, and thus there was a bifurcation in sector performance. Traditionally defensive sectors, most notably, consumer staples, health care and utilities, performed best within the Russell Index on a relative basis for the annual period overall, each generating double-digit returns. More cyclical, economically-sensitive sectors, including financials, materials and energy, were the weakest performers in the Russell Index during the annual period. Financials negative returns within the Russell Index were impacted most severely by concerns surrounding the European sovereign debt crisis and its potential contagion effect. Materials and energy were particularly hurt by a broad slowdown in global industrial growth.

Lost ground from financials, consumer discretionary, health care and energy

The fund's results were hurt most by stock selection in the financials sector, which more than offset the positive contribution made by having an underweighted allocation to the worst performing sector in the index during the annual period. An emphasis on

Portfolio Manager's Report (continued) – Columbia Large Cap Value Fund

capital markets firms and large diversified banks hindered results most. We had established exposures to these industries because it was there that we found companies with the deepest discounts to their long-term valuations. However, capital markets firms such as Goldman Sachs and Morgan Stanley performed poorly during the annual period on lower levels of capital markets activity due to concerns over broad regulatory changes and volatility in the global capital markets. Positions in diversified banks JPMorgan Chase and Bank of America hurt the fund's results as these companies faced revenue challenges based on controversy around retail fees and on ongoing costs incurred in restructuring their mortgage portfolios. A fund position in insurance company MetLife also detracted, primarily during the first months of the annual period.

Industry and stock selection in the consumer discretionary sector further detracted from the fund's results during the annual period. Specifically, greater exposure to the auto and auto parts and leisure industries, which lagged the index, and having underweighted exposure to a variety of industries within the sector, such as media, which performed better, hurt. In the auto and auto parts industry, a sizable position in automobile manufacturer Ford Motor hindered results. In the leisure industry, a significant holding in cruise line Carnival hurt the fund's relative performance. Such detractors within the consumer discretionary sector were partially offset by a sizable position in home improvement retailer Home Depot, which was a strong performer for the fund during the annual period.

In health care, the second best performer in the index during the annual period, having an underweighted exposure to the sector and industry and stock selection detracted. Having an underweighted allocation to the pharmaceuticals industry particularly hindered results, as this was one of the better performing areas of the sector.

Stock selection in the energy sector negatively impacted the fund's annual results with an overweighted allocation to the poorly performing sector also hampering relative returns. Stock selection was especially challenging in the oilfield services and exploration and production industries, with Halliburton and Apache delivering particularly disappointing results.

Contributions from information technology and consumer staples

Stock selection in the information technology and consumer staples sectors proved effective. In information technology, an emphasis on the services industries boosted results most. In particular, sizable positions in global payment solutions provider MasterCard, computer solutions provider International Business Machines (IBM) and software giant Microsoft benefited the fund during the annual period. Fund positions in personal computer and mobile communications device behemoth Apple and semiconductor manufacturer LSI also boosted results.

In consumer staples, a significant exposure to the tobacco industry contributed most positively to the fund's results, with positions in Lorillard and Philip Morris International each adding value. The fund also benefited during the annual period from underweighted exposure to industries within the consumer staples sector facing rising input costs, such as food products, which lagged.

Portfolio Manager's Report (continued) – Columbia Large Cap Value Fund

Transitioning to a new portfolio management team

Most of the changes to the fund's portfolio were made during the third quarter of 2011, both as part of the transition to the new portfolio management team and given broad equity market volatility that dominated during those months. In transitioning to the new portfolio management team, we established certain exposures at the sector and industry level that differed from the benchmark and somewhat reduced the number of holdings in the portfolio—from 99 names at the start of the annual period to 87 at the end of February 2012.

Overall, we substantially increased the fund's allocation to the information technology sector. Within the sector, we established new positions in Microsoft, MasterCard, semiconductor bellwether Intel and networking products manufacturer Cisco Systems. To a lesser extent, the fund's exposure to materials and consumer staples also increased over the course of the annual period. In materials, we bought positions in diversified chemicals companies Dow Chemical and E. I. du Pont de Nemours and added to the fund's position in metals miner Freeport-McMoRan Copper and Gold. In consumer staples, we initiated new fund positions in Lorillard and drug store retailer CVS Caremark and expanded the fund's position in Philip Morris Int'l.

Conversely, we decreased the fund's allocation to the financials sector most. Within financials, the largest eliminations included Prudential, U.S. Bancorp and PNC Financial. We also trimmed the fund's positions in Wells Fargo and Citigroup. During the annual period, we additionally reduced the fund's exposures to the utilities and consumer discretionary sectors. In utilities, we eliminated the fund's positions in NextEra Energy and American Electric Power and trimmed its position in PG&E, each an integrated electric utility. In consumer discretionary, we sold the fund's positions in auto manufacturer General Motors and auto parts distributor Genuine Parts and reduced its positions in cruise line Carnival and multimedia company Viacom.

With these changes, it is well worth noting that at the end of February 2012, the fund had its most significant weightings compared to the Russell Index in the industrials, information technology and materials sectors and its most modest exposures relative to the benchmark index in the financials, utilities and telecommunication services sectors.

Equity securities are affected by stock market fluctuations that occur in response to economic and business developments.

Value stocks are securities of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor. If the managers' assessment of a company's prospects is wrong, the price of the company's stock may not approach the value the manager has placed on it.

Fair Value Measurements

Generally accepted accounting principles (GAAP) require disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category.

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund's assumptions about the information market participants would use in pricing an investment. An investment's level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability's fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

The Accompanying Notes to Financial Statements are an integral part of this statement.

Columbia Large Cap Value Fund

February 29, 2012

Fair Value Measurements (continued)

Fair value inputs are summarized in the three broad levels listed below:

• Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date (including NAV for open-end mutual funds). Valuation adjustments are not applied to Level 1 investments.

• Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

• Level 3 — Valuations based on significant unobservable inputs (including the Fund's own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment's fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund's investments as of February 29, 2012:

Notes to Financial Statements – Columbia Large Cap Value Fund
February 29, 2012

Note 1. Organization

Columbia Large Cap Value Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class I, Class R, Class W, Class Y and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class A shares are subject to a maximum front-end sales charge of 5.75% based on the initial investment amount. 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) if the shares are sold within 18 months of purchase, charged as follows: 1.00% CDSC if redeemed within 12 months of purchase, and 0.50% CDSC if redeemed more than 12, but less than 18, months after purchase.

Class B shares may be subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will generally convert to Class A shares eight years after purchase. The Fund no longer accepts investments by new or existing investors in the Fund's Class B shares, except in connection with the reinvestment of any dividend and/or capital gain distributions in Class B shares of the Fund and exchanges by existing Class B shareholders of certain other funds within the Columbia Family of Funds.

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are only available to qualifying institutional investors.

Class W shares are not subject to sales charges and are only available to investors purchasing through authorized investment programs managed by investment professionals, including discretionary managed account programs.

Class Y shares are not subject to sales charges and are only available to certain categories of investors which are subject to minimum initial investment requirements.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles (GAAP) requires management to make certain 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

All equity securities are valued at the close of business of the New York Stock Exchange (NYSE). Equity securities are valued at the last quoted sales price on the principal exchange or market on which they trade, except for securities traded on the NASDAQ Stock Market, 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 mean of the latest quoted bid and asked prices on such exchanges or markets.

Debt securities generally are valued by pricing services approved by the Board of Trustees (the Board) 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 may also be valued based upon an over-the-counter or exchange bid quotation.

Columbia Large Cap Value Fund, February 29, 2012

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board, including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Short-term securities purchased within 60 days to maturity are valued at amortized cost, which approximates market value. The value of short-term securities originally purchased with maturities greater than 60 days is determined based on an amortized value to par upon reaching 60 days to maturity. Short-term securities maturing in more than 60 days from the valuation date are valued at the market price or approximate market value based on current interest rates.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Investments for which market quotations are not readily available, or that have quotations which management believes are not reliable, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the last quoted market price for the security. The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine value.

Foreign Currency Transactions and Translation

The values of all assets and liabilities denominated 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 and translations 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.

Derivative Instruments

The Fund invests in certain derivative instruments as detailed below to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more other assets, such as securities, currencies, commodities or indices. Derivative instruments may be used to maintain cash reserves while maintaining exposure to certain other assets, to offset anticipated declines in values of investments, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligation under the terms of the contract, the potential for an illiquid secondary market and the potential for market movements which may expose the Fund to gains or losses in

Columbia Large Cap Value Fund, February 29, 2012

excess of the amount shown in the Statement of Assets and Liabilities.

The Fund and any counterparty are required to maintain an agreement that requires the Fund and that counterparty to monitor (on a daily basis) the net fair value of all derivatives entered into pursuant to the agreement between the Fund and such counterparty. If the net fair value of such derivatives between the Fund and that counterparty exceeds a certain threshold (as defined in the agreement), the Fund or the counterparty (as the case may be) is required to post cash and/or securities as collateral. Fair values of derivatives presented in the financial statements are not netted with the fair value of other derivatives or with any collateral amounts posted by the Fund or any counterparty.

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are agreements between two parties to buy and sell a currency at a set price on a future date. These contracts are intended to be used to minimize the exposure to foreign exchange rate fluctuations during the period between the trade and settlement dates of the contract. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund's securities, to shift foreign currency exposure back to U.S. dollars, to shift investment exposure from one currency to another, and to shift U.S. dollar exposure to achieve a representative weighted mix of major currencies in its benchmark, and/or to recover an underweight country exposure in its portfolio.

The values of forward foreign currency exchange contracts fluctuate with changes in foreign currency exchange rates. The Fund will record a realized gain or loss when the forward foreign currency exchange contract is closed.

The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund's portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Statement of Assets and Liabilities.

Effects of Derivative Transactions in the Financial Statements

The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; the impact of derivative transactions on the Fund's operations over the period including realized gains or losses and unrealized gains or losses. The derivative schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Fund, through the custodian, receives

Columbia Large Cap Value Fund, February 29, 2012

delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

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.

Income Recognition

Corporate actions and dividend income are recorded on the ex-dividend date.

Interest income is recorded on the accrual basis.

The Fund receives distributions from holdings in real estate investment trusts (REITs) which report information on the character of their distributions annually. REIT distributions are allocated to dividend income, capital gain and return of capital based on estimates made by the Fund's management if actual information has not yet been reported. Return of capital is recorded as a reduction of the cost basis of securities held. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs which could result in a proportionate increase in return of capital to shareholders.

Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains.

Expenses

General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.

Determination of Class Net Asset Value

All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.

Federal Income Tax Status

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its tax exempt or taxable income (including net short-term capital gains), 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 from net investment income, if any, are declared and paid each calendar quarter. Net realized capital gains, if any, are distributed along with the income dividend. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations which may differ from GAAP.

Guarantees and Indemnifications

Under the Trust's organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund's contracts with its service providers contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be

Columbia Large Cap Value Fund, February 29, 2012

determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Recent Accounting Pronouncement

Fair Value Measurements and Disclosures

In May 2011, the Financial Accounting and Standards Board (FASB) issued ASU No. 2011-04 modifying Topic 820, Fair Value Measurements and Disclosures. At the same time, the International Accounting Standards Board (IASB) issued International Financial Reporting Standard 13, Fair Value Measurement. The objective of the FASB and IASB is convergence of their guidance on fair value measurements and disclosures.

Specifically, ASU No. 2011-04 requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2, and the reasons for the transfers, ii) for Level 3 fair value measurements, a) quantitative information about significant unobservable inputs used, b) a description of the valuation processes used by the reporting entity and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of ASU No. 2011-04 is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have on the financial statement amounts and footnote disclosures, if any.

Note 4. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement (IMSA), Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), determines which securities will be purchased, held or sold. Effective July 1, 2011, the management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.71% to 0.54% as the Fund's net assets increase. Prior to July 1, 2011, the management fee was equal to a percentage of the Fund's average daily net assets that declined from 0.60% to 0.41% as the Fund's net assets increased. The effective management fee rate for the year ended February 29, 2012 was 0.60% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. Effective July 1, 2011, the Fund pays the Fund Administrator an annual fee for administration and accounting services equal to a percentage of the Fund's average daily net assets that declines from 0.06% to 0.03% as the Fund's net assets increase. Prior to July 1, 2011, the administration fee was equal to the annual rate of 0.17% of the Fund's average daily net assets, less the fees that were payable by the Fund as described under the Pricing and Bookkeeping Fees note below. The effective administration fee rate for the year ended February 29, 2012 was 0.10% of the Fund's average daily net assets.

Pricing and Bookkeeping Fees

Prior to July 25, 2011, the Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Fund. The Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Fund. Under the State Street Agreements, the Fund paid 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. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective July 25, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Columbia Large Cap Value Fund, February 29, 2012

facilitated by a company providing limited administrative services to the Fund and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $5,505.

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not "interested persons" of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund's liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by Columbia. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with Boston Financial Data Services (BFDS) to serve as sub-transfer agent.

The Transfer Agent receives monthly account-based service fees based on the number of open accounts and is reimbursed by the Fund for the fees and expenses the Transfer Agent pays to financial intermediaries that maintain omnibus accounts with the Fund that is a percentage of the average aggregate value of the Fund's shares maintained in each such omnibus account (other than omnibus accounts for which American Enterprise Investment Services Inc. is the broker of record or accounts where the beneficial shareholder is a customer of Ameriprise Financial Services, Inc., which are paid a per account fee). The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A	0.19	%
Class B	0.19
Class C	0.18
Class R	0.16
Class W	0.15
Class Y	0.00	*
Class Z	0.18

* Rounds to less than 0.01%.

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the Fund's initial minimum investment requirements to reduce the impact of small accounts on transfer agent fees. These minimum account balance fees are recorded as part of expense reductions in the Statement of Operations. For the year ended February 29, 2012, these minimum account balance fees reduced total expenses by $36,791.

Distribution and Service Fees

Columbia Large Cap Value Fund, February 29, 2012

and shareholder service plans (the Plans) which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also required the payment of a monthly service fee at the maximum annual rate of 0.25% of the average daily net assets attributable to Class B, Class C and Class W shares of the Fund and the payment of a monthly distribution fee at the maximum annual rates of 0.75%, 0.75%, 0.50% and 0.25% of the average daily net assets attributable to Class B, Class C, Class R and Class W shares, respectively.

The Fund may pay a distribution fee of up to 0.25% of the Fund's average daily net assets attributable to Class W shares and a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class W shares, provided, however, that the aggregate fee shall not exceed 0.25% of the Fund's average daily net assets attributable to Class W shares.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $125,422 for Class A, $12,360 for Class B and $2,168 for Class C shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective July 1, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund's net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, do not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.11	%
Class B	1.86
Class C	1.86
Class I	0.75
Class R	1.36
Class W	1.11
Class Y	0.86
Class Z	0.86

Under the agreement, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, extraordinary expenses and any other expenses the exclusion of which is specifically approved by the Board. This agreement may be modified or amended only with approval from all parties.

Prior to July 1, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund's expenses (excluding certain expenses, such as brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund's ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges

Columbia Large Cap Value Fund, February 29, 2012

from the Fund's custodian, did not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.25	%
Class B	2.00
Class C	2.00
Class I	0.87
Class R	1.50
Class W	1.25
Class Y	1.00
Class Z	1.00

Note 5. 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 because of temporary or permanent book to tax differences.

For the year ended February 29, 2012, these differences are primarily due to differing treatment for capital loss carryforwards deferral/reversal of wash sales losses, Trustees deferred compensation, foreign currency transactions, and post-October capital losses. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Undistributed net investment income	$	(38,018	)
Accumulated net realized loss		35,795
Paid-in capital		2,223

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

The tax character of distributions paid during the years indicated was as follows:

Year ended				February 29, 2012				February 28, 2011
Ordinary income				$	16,444,671			$	26,828,023

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income				$	4,245,295
Unrealized appreciation					180,640,823

At February 29, 2012, the cost of investments for federal income tax purposes was $1,470,740,170 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	227,379,679
Unrealized depreciation	$	(46,738,856	)
Net unrealized appreciation/depreciation	$	180,640,823

The following capital loss carryforward, determined at February 29, 2012, 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				Amount
2018				$	410,394,653

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Act) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. Under the Act, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused.

For the year ended February 29, 2012, $224,121,077 of capital loss carryforward was utilized.

Columbia Large Cap Value Fund, February 29, 2012

Under current tax rules, regulated investment companies can elect to treat certain late-year ordinary losses incurred and post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. As of February 29, 2012, the Fund will elect to treat post-October capital losses of $7,414,614 as arising on March 1, 2012.

Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. However, management's conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 6. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $1,207,057,676 and $1,700,251,878, respectively, for the year ended February 29, 2012.

Note 7. Regulatory Settlements

During the year ended February 29, 2012, the Fund received payments of $7,701 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Note 8. Lending of Portfolio Securities

Effective Juy 25, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $156,909,311 were on loan, secured by U.S. government securities valued at $19,133 and by cash collateral of $160,891,975 invested in short-term securities or in cash equivalents (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower's failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Pursuant to the Agreement, the Fund receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses. Net income earned from securities lending for the year ended February 29, 2012 is disclosed in the Statement of Operations. The Fund continues to earn and accrue interest and dividends on the securities loaned.

Prior to July 25, 2011, the Fund participated in a securities lending arrangement with State Street. Each security on loan was collateralized in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The income generated by the investment of the collateral, net of any fees remitted to State

Columbia Large Cap Value Fund, February 29, 2012

Street as the lending agent and borrower rebates, was paid to the Fund.

Note 9. Custody Credits

Prior to July 25, 2011, the Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through July 25, 2011, there were no credits.

Note 10. Affiliated Money Market Fund

Effective July 25, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as "Dividends from affiliates" in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 11. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned 47.6% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund.

Note 12. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 25, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 25, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

For the period June 27, 2011 through July 24, 2011, the Fund and certain other funds managed by the Investment Manager participated in a $100 million committed, unsecured revolving credit facility provided by State Street. For the period May 16, 2011 through June 26, 2011, the collective borrowing amount of the credit facility was $150 million committed, unsecured revolving credit facility provided by State Street. For the period March 28, 2011 through May 15, 2011, the collective borrowing amount of the credit facility was $225 million. Prior to March 28, 2011, the collective borrowing amount of the credit facility was $280 million. Interest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum. The Fund had no borrowings during the year ended February 29, 2012.

Note 13. Subsequent Events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than noted below, there were no items requiring adjustment of the financial statements or additional disclosure. On March 23, 2012, a group of unaffiliated shareholders of the Fund redeemed $137,646,441, which represented approximately 9% of the Fund's net assets as of that date. On April 20, 2012, the same group of unaffiliated

Columbia Large Cap Value Fund, February 29, 2012

shareholders redeemed $133,352,436, which represented approximately 10% of the Fund's net assets as of that date.

Note 14. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and ruled in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendents.

In December 2005, without admitting or denying the allegations, American Express Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc. (Ameriprise Financial)) entered into settlement agreements with the Securities and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC) related to market timing activities. As a result, AEFC was censured and ordered to cease and desist from committing or causing any violations of certain provisions of the Investment Advisers Act of 1940, the Investment Company Act of 1940, and various Minnesota laws. AEFC agreed to pay disgorgement of $10 million and civil money penalties of $7 million. AEFC also agreed to retain an independent distribution consultant to assist in developing a plan for distribution of all disgorgement and civil penalties ordered by the SEC in accordance with various undertakings detailed at www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its affiliates have cooperated with the SEC and the MDOC in these legal proceedings, and have made regular reports to the funds' Boards of Trustees.

Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Funds are not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as necessary, 8-K filings with the Securities and Exchange Commission on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.

Columbia Large Cap Value Fund, February 29, 2012

There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased fund redemptions, reduced sale of fund shares or other adverse consequences to the Funds. Further, although we believe proceedings are not likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Large Cap Value 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 Large Cap Value Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent, provide a reasonable basis for our opinion.

Fund Governance

Shareholders elect the Board that oversees the funds' operations. The Board appoints officers who are responsible for day-to-day business decisions based on policies set by the Board. The following table provides basic biographical information about the funds' Board members, including their principal occupations during the past five years, although specific titles for individuals may have varied over the period. Under current Board policy, members may serve until the next Board meeting after he or she reaches the mandatory retirement age established by the Board, or the fifteenth anniversary of the first Board meeting they attended as a member of the Board.

On September 29, 2009, Ameriprise Financial, the parent company of Columbia Management, entered into an agreement with Bank of America, N.A. ("Bank of America") to acquire a portion of the asset management business of Columbia Management Group, LLC and certain of its affiliated companies (the "Transaction"). Following the Transaction, which became effective on May 1, 2010, various alignment activities have occurred with respect to the Fund Family. In connection with the Transaction, Mr. Edward J. Boudreau, Jr., Mr. William P. Carmichael, Mr. William A. Hawkins, Mr. R. Glenn Hilliard, Mr. John J. Nagorniak, Ms. Minor M. Shaw and Dr. Anthony M.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –3.27% without sales charge. The fund underperformed its benchmark, the MSCI All Country World Index ND (net of dividends), which returned –1.49%. The consumer staples and health care sectors were the strongest performers in the benchmark index, but the fund had few investments in these areas, which detracted from performance. Stock selection in the consumer discretionary and energy sectors also hurt results. Stock selection in the industrials, materials and health care sectors was strong and aided results.

In October 2011 the fund's management changed. Cory Gilchrist left the firm to pursue personal and charitable interests. Tom Marsico and Jim Gendelman continue to serve as co-portfolio managers of the fund.

Stock selection, sector weights hurt results

Stock selection in the energy sector was weak, with oil and gas exploration and production companies OGX Petróleo e Gás Participações and Ultra Petroleum each posting significant declines prior to being sold from the fund. Several consumer discretionary positions materially hurt results, including Hong Kong-based consumer goods firm Li & Fung (0.9% of net assets), General Motors and Walt Disney. The latter two positions were also sold during the period. Sector allocations also restrained results. The fund was underweight in the consumer staples and health care sectors, both of which were the strongest-performing sectors in the benchmark index.

Favorable stock selection in industrials, health care and materials

Stock selection was strong in the industrials sector. Several holdings posted double-digit returns, including aerospace components company Precision Castparts, engine manufacturer Cummins and Internet-based consumer banking information provider Bankrate (2.7%, 1.8% and 1.3% of net assets, respectively). In health care, Intuitive Surgical (4.1% of net assets), which makes a robotic system for assisting in minimally invasive surgeries, was among the fund's strongest performing individual positions. Other good performers included consumer electronics firm Apple and Latin American e-commerce company MercadoLibre (7.5% and 2.5% of net assets, respectively). In the materials sector, specialty chemicals firm Dow Chemical (1.8% of net assets) posted sharp stock price appreciation. Overall, the materials sector was a weak performer in the index, and the fund benefitted from having few investments in the group.

Portfolio Managers' Report (continued) – Columbia Marsico Global Fund

Fund positioning intended to reflect economic scenarios

By the end of the period, we sought to position the portfolio to reflect both uncertainty in Europe as well as a more constructive scenario in which the euro zone stabilizes and global growth reaccelerates. Hence, a number of holdings are more defensive in nature, with business models that have proven to be less susceptible to adverse macroeconomic conditions and that are capable of generating solid top-line growth and dependable revenues. Another segment of the portfolio is represented by cyclical companies that have the potential to benefit if the euro zone moves closer to a solution and global economic conditions continue to improve. A final segment of the portfolio consists of stocks selected from a purely bottom-up perspective, which we view as unique stories and compelling investments.

The Accompanying Notes to Financial Statements are an integral part of this statement.

Columbia Marsico Global Fund

February 29, 2012

Fair Value Measurements (continued)

• Level 3 — Valuations based on significant unobservable inputs (including the Fund's own assumptions and judgment in determining the fair value of investments).

Foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange (NYSE) are classified as Level 2. The values of these securities may include an adjustment to reflect the impact of significant market movements following the close of local trading, as described in Note 2 to the financial statements — Security Valuation.

The following table is a summary of the inputs used to value the Fund's investments as of February 29, 2012:

The Fund's assets assigned to the Level 2 input category are generally valued using the market approach, in which a security's value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The models utilized by the third party statistical pricing service take into account a security's correlation to available market data including, but not limited to, intraday index, ADR, and ETF movements.

(a) See the Portfolio of Investments for all investment classifications not indicated in the table.

(b) There were no significant transfers between Levels 1 and 2 during the period.

(c) Derivative instruments are valued at unrealized appreciation (depreciation).

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Columbia Marsico Global Fund, February 29, 2012

Short-term securities maturing in more than 60 days from the valuation date are valued at the market price or approximate market value based on current interest rates.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Foreign Currency Transactions and Translation

Derivative Instruments

Forward Foreign Currency Exchange Contracts

The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund's portfolio securities. The risks of forward foreign currency exchange

Columbia Marsico Global Fund, February 29, 2012

contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Statement of Assets and Liabilities.

Interest income is recorded on the accrual basis.

Columbia Marsico Global Fund, February 29, 2012

Expenses

Determination of Class Net Asset Value

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 (including net short-term capital gains), 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.

Foreign Taxes

The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed along with the income dividend. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations which may differ from GAAP.

Fair Value Measurements and Disclosures

Columbia Marsico Global Fund, February 29, 2012

fair value measurement. The effective date of ASU No. 2011-04 is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have on the financial statement amounts and footnote disclosures, if any.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), is responsible for the ultimate oversight of investments made by the Fund. The primary responsibility for the day-to-day portfolio management of the Fund is provided by the Fund's subadviser (see Subadvisory Agreement below). The Management fee is an annual fee that is equal to 0.80% of the Fund's average daily net assets.

Subadvisory Agreement

The Investment Manager has entered into a Subadvisory Agreement with Marsico Capital Management, LLC (Marsico) to subadvise the assets of the Fund. The Investment Manager compensates Marsico to manage the investments of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.22% of the Fund's average daily net assets, less the fees that were payable by the Fund as described under the Pricing and Bookkeeping Fees note below. In the event the administrator fee paid to the Investment Manager was not sufficient to cover the Pricing and Bookkeeping fees, the Investment Manager paid the additional Pricing and Bookkeeping fees on behalf of the Fund.

Pricing and Bookkeeping Fees

Prior to July 11, 2011, the Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Fund. The Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Fund. Under the State Street Agreements, the Fund paid 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. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective July 11, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Effective June 1, 2011, other expenses are for, among other things, certain expenses of the Fund or the Board, including: Fund boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. Payment of these Fund and Board expenses is facilitated by a company providing limited administrative services to the Fund and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $1,243.

Compensation of Board Members

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations.

Columbia Marsico Global Fund, February 29, 2012

Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A	0.09	%
Class C	0.09
Class R	0.09
Class Z	0.09

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the Fund's initial minimum investment requirements to reduce the impact of small accounts on transfer agent fees. These minimum account balance fees are recorded as part of expense reductions in the Statement of Operations. For the year ended February 29, 2012, no minimum account balance fees were charged by the Fund.

Distribution and Service Fees

The Fund has an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. Pursuant to Rule 12b-1 under the 1940 Act, the Board has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also required the payment of a monthly service fee at the maximum annual rate of 0.25% of the average daily net assets attributable to Class C shares of the Fund and the payment of a monthly distribution fee at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $36,999 for Class A and $200 for Class C shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Columbia Marsico Global Fund, February 29, 2012

terminated at the sole discretion of the Board, so that the Fund's net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, do not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.60	%
Class C	2.35
Class R	1.85
Class Z	1.35

Class A	1.60	%
Class C	2.35
Class R	1.85
Class Z	1.35

Prior to May 1, 2011, the Investment Manager was entitled to recover from the Fund any fees waived and/or expenses reimbursed for a three year period following the date of such fee waiver and/or reimbursement under these arrangements if such recovery did not cause the Fund's expenses to exceed the expense limitations in effect at the time of recovery. Effective May 1, 2011, the Investment Manager has eliminated such fee recoupment provisions.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for net operating loss reclassifications, post-October losses, capital loss carryforward limitations related to ownership changes, capital loss carryforwards, passive foreign investment company (PFIC) holdings, late year ordinary losses, foreign currency transactions and deferral/reversal of wash sales. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Excess of distributions over
net investment income	$	119,606
Accumulated net realized loss		(38,734	)
Paid-in capital		(80,872	)

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

The tax character of distributions paid during the years indicated was as follows:

Year ended	February 29, 2012		February 28, 2011
Ordinary income	$	8,900	$	35,349
Long-term capital gains		86,952		—
Tax return of capital		6,943		—

Columbia Marsico Global Fund, February 29, 2012

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	—
Undistributed long-term capital gains		—
Unrealized appreciation		1,493,213

At February 29, 2012, the cost of investments for federal income tax purposes was $7,156,327 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	1,516,443
Unrealized depreciation	$	(23,230	)
Net unrealized appreciation	$	1,493,213

Year of Expiration	Amount
2018	$	1,122,487
Unlimited short-term		207,373
Total	$	1,329,860

Under current tax rules, regulated investment companies can elect to treat certain late-year ordinary losses incurred and post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. As of February 29, 2012, the Fund will elect to treat late year ordinary losses of $20,057 and post-October capital losses of $101,692 as arising on March 1, 2012.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $10,001,047 and $9,090,440, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

Effective July 11, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous securities lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to

Columbia Marsico Global Fund, February 29, 2012

return the collateral upon the return of the securities loaned. For the year ended February 29, 2012, the Fund did not participate in securities lending activity.

Pursuant to the Agreement, the Fund receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses. The Fund continues to earn and accrue interest and dividends on the securities loaned.

Prior to July 11, 2011, the Fund participated in a securities lending arrangement with State Street. Each security on loan was collateralized in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, was paid to the Fund.

Note 7. Custody Credits

Prior to July 11, 2011, the Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through July 10, 2011, there were no custody credits.

Note 8. Affiliated Money Market Fund

Effective July 11, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as "Dividends from affiliates" in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 9. Shareholder Concentration

At February 29, 2012, affiliated shareholder accounts owned 55.8% of the outstanding shares of the Fund. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 10. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 11, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 11, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Columbia Marsico Global Fund, February 29, 2012

Prior to July 11, 2011, the Fund and certain other funds managed by the Investment Manager participated in a committed, unsecured revolving credit facility provided by State Street. For the period June 27, 2011 through July 8, 2011, the collective borrowing amount of the credit facility was $100 million. For the period May 16, 2011 through June 26, 2011, the collective borrowing amount of the credit facility was $150 million. For the period March 28, 2011 through May 15, 2011, the collective borrowing amount of the credit facility was $225 million. Prior to March 28, 2011, the collective borrowing amount of the credit facility was $280 million. Interest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 11. Significant Risks

Foreign Securities Risk

Investing in foreign securities may include certain risks and considerations not typically associated with investing in U.S. securities, such as fluctuating currency values and changing local and regional economic, political and social conditions, which may result in greater market volatility. In addition, certain foreign securities may not be as liquid as U.S. securities. Investing in emerging markets may accentuate these risks.

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.

Note 12. Subsequent Events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.

Note 13. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and rule in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response

Columbia Marsico Global Fund, February 29, 2012

brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Marsico Global 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 Marsico Global Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent, provide a reasonable basis for our opinion.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned 5.00% without sales charge. The fund's benchmark, the S&P 500 Index, returned 5.12%. Stock selection and an emphasis on the consumer discretionary sector relative to the index aided performance. Stock selection in the industrials and materials sectors also was strong. The fund had less exposure than the index to the three strongest-performing sectors—utilities, consumer staples and health care—which detracted from performance. Specific stocks in information technology, health care and energy also disappointed.

U.S. economy picks up momentum

During the first half of the 12-month period, a series of natural disasters in Japan, Europe's debt problems and wrangling in Washington over the federal budget and the national debt dominated world headlines. U.S. economic news was lackluster and job growth was disappointing. However, the pace of growth picked up in the second half of the period and, as fears of a lapse back into recession faded, prospects brightened. Consumer confidence improved even though consumers remain under pressure, with no real increase in disposable income and a continued decline in household net worth. The labor markets added more than a million new jobs from September 2011 through February 2012, and the jobless rate fell to 8.3%. A modest slowdown in manufacturing activity late in the summer of 2011 raised concern that this lynchpin of the recovery was ready to turn downward. However, manufacturing activity stabilized and the manufacturing expansion continued into 2012. Housing continues to be the one nagging weak spot in the economy. Yet, home sales edged modestly higher over the year, and there is hope that a bottom in the housing market is in sight.

Consumer discretionary, underweight in financials aid results

As the economy improved, the consumer discretionary sector was a strong performer, and the fund benefited from an overweight in the sector relative to the index. In addition, several individual consumer names were strong performers, including retailer TJX, specialty coffee retailer Starbucks, restaurant operator YUM! Brands and online travel reservations firm priceline.com (4.5%, 3.0%, 1.7% and 3.2% of net assets, respectively). In the industrials and materials sectors, Union Pacific, the largest public railroad in the U.S., Precision Castparts, which manufactures complex metal components for industrial applications, and industrial gas supplier Praxair (2.9%, 2.3% and 2.5% of net assets, respectively) contributed positively to results.

With the regulatory climate for the financial services sector becoming considerably more complex, we significantly reduced the fund's allocation to financials during the period. This decision aided performance as the sector was the weakest performer in the index.

Sector positioning, stock selection disappointed

The fund had few investments in the three strongest-performing sectors of the S&P 500 Index: utilities, consumer staples and health care. This positioning hurt performance. Elsewhere in the portfolio, certain stocks detracted from return. In information technology, Chinese Internet television firm Youku.com (0.6% of net assets), enterprise software provider Oracle and Acme Packet, which sells

Portfolio Managers' Report (continued) – Columbia Marsico Growth Fund

telecommunications equipment used for the delivery of real-time audio and video via Internet, all posted double-digit losses. We sold Oracle and Acme Packet from the portfolio. Within health care, Agilent Technologies, a leading provider of test and measurement products, declined sharply and was sold. Energy sector holding Halliburton (2.6% of net assets), which provides oilfield service, had a negative return as well.

Portfolio activity

During the 12-month period, we took a number of steps aimed at reducing the fund's emphasis on economically-sensitive companies. We pared exposure to industrials and materials and pulled back significantly from financial stocks. We increased investments in companies that we believe have durable franchises with dependable revenue streams that we think are capable of compounding their earnings growth even in a choppy economic environment. These companies span a variety of industries but share several common factors, such as an established global footprint, high quality assets, solid top-line unit growth and an ability to gain market share.

Looking ahead

At the end of the period, the portfolio was positioned to balance the uncertainty in Europe against a more constructive scenario in which the euro zone stabilizes and global growth accelerates. Hence, a number of holdings are more defensive in nature, with business models that have proven to be less susceptible to adverse macroeconomic conditions and with the potential to generate solid top-line growth and dependable revenues. Another segment of the portfolio is represented by cyclical companies that should benefit if the euro zone moves closer to a solution and global economic conditions continue to improve. A final segment of the portfolio consists of stocks selected from a purely bottom-up perspective, which we view as unique stories and compelling investments.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Columbia Marsico Growth Fund, February 29, 2012

service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Foreign Currency Transactions and Translation

Derivative Instruments

Forward Foreign Currency Exchange Contracts

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Fund, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), is responsible for the ultimate oversight of investments made by of the Fund. The primary responsibility for the day-to-day portfolio management of the Fund is provided by the Fund's subadviser (see Subadvisory Agreement below). The management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.75% to 0.56% as the Fund's net assets increase. The effective management fee rate for the year ended February 29, 2012 was 0.65% of the Fund's average daily net assets.

To the extent that the Fund is not benefitting from a separate contractual expense limitation arrangement, the Investment Manager has contractually agreed to waive a portion of its management fee through June 30, 2012. In the absence of a separate contractual expense limitation arrangement, the management fee waiver for the Fund would be calculated as follows:

Fund average daily net assets*	Management fee waiver
Assets up to $18 billion		0.00	%
Assets in excess of $18 billion and up to $21 billion		0.05
Assets in excess of $21 billion		0.10

* For purposes of the calculation, "Assets" are aggregate assets of the Fund and other affiliated funds managed by the Investment Manager and sub-advised by Marsico Capital Management, LLC.

For the year ended February 29, 2012, no management fees were waived for the Fund.

under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund's liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager.

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

Note 7. Lending of Portfolio Securities

Effective July 11, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $84,854,299 were on loan, secured by U.S. government securities valued at $11,374,238 and by cash collateral of $75,936,069 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Note 8. Custody Credits

Note 9. Affiliated Money Market Fund

Note 10. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned 39.3% of the outstanding shares of the Fund. The Fund

Columbia Marsico Growth Fund, February 29, 2012

has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 11, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 11, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

For the year ended February 29, 2012, the average daily loan balance outstanding on days when borrowing existed was $4,163,636 at a weighted average interest rate of 1.33%.

are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and rule in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Marsico Growth 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 Marsico Growth Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent, provide a reasonable basis for our opinion.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares and 1.00% for Class C shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower.

All results shown assume reinvestment of distributions. Class I and Class Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class R shares are sold at net asset value with a distribution (12b-1) fee. Class I, Class R and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

*The returns shown for periods prior to the share class inception date (including returns since inception, which are since Fund inception) include the returns of the Fund's Class A shares, the fund's oldest share class. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –6.02% without sales charge. The fund's benchmark, the MSCI EAFE Index (Net), returned –7.45%. The fund's stock selection in the information technology and industrials sectors helped mitigate losses in the consumer discretionary and energy sectors. An underweight allocation to the weak-performing financials, utilities and materials sectors also benefited results. The impact of currency activity was negative for the period.

Stock selection delivered mixed results

Stock selection in the information technology and industrials sectors aided results. Argentinean e-commerce company MercadoLibre (1.5% of net assets) experienced a strong stock price gain. Semiconductor positions Taiwan Semiconductor Manufacturing and ASML Holding (2.0% and 1.5% of net assets, respectively) posted solid results. In the industrials sector, jet engine manufacturer Rolls-Royce, Canadian National Railway and Japan-based industrial robotics company FANUC (1.2%, 2.5% and 2.0% of net assets, respectively) each posted strong returns.

Materials holdings were led by ThyssenKrupp, a diversified materials and technology conglomerate, and Novozymes (1.1% of net assets), a biotechnology company. ThyssenKrupp was sold. Brazilian real estate company BR Malls Participações (1.7% of net assets) was a meaningful contributor to performance.

Stock selection in the consumer discretionary and energy sectors hurt performance. In the former, Hong Kong-based manufacturer, exporter and distributor of retail goods Li & Fung (1.0% of net assets), casino firm Genting Singapore and Brazilian professional education company Anhanguera Educacional Participações all declined markedly in price. The latter two stocks were sold from the fund. Oil and gas exploration firms OGX Petróleo e Gás Participações and Pacific Rubiales Energy (2.3% and 1.1% of net assets, respectively) declined sharply as well.

In the financials sector, Citigroup (1.5% of net assets), which has a growing emerging markets presence, and Barclays were poor performers. We sold Barclays from the portfolio. Meanwhile, an overweight allocation to the weak-performing information technology sector and underweights in the strong consumer staples and health care sectors restrained fund performance.

Currency fluctuations hurt results

Fluctuations in currencies were an additional source of fund underperformance during the period. From early April through early August 2011, about half of the fund's Japanese yen-denominated holdings were hedged into U.S. dollars. This was a capital preservation strategy based on our view that the yen was significantly overvalued relative to the dollar on a purchasing power parity basis. However, the yen continued to appreciate versus the dollar and other major currencies. Thus, the hedge detracted from performance. We unwound the hedge after Standard & Poor's downgraded its rating on long-term U.S. government debt in August, as we thought currencies such as the yen might continue to strengthen against the dollar and euro.

Portfolio Managers' Report (continued) – Columbia Marsico International Opportunities Fund

Looking ahead

During the period, we increased the fund's allocation to the information technology and health care sectors, while reducing its weight in the materials, financials and industrials sectors. Within financials, we significantly cut the fund's exposure to European financial companies. In general, we are focusing on investments with company- and industry-specific growth drivers rather than macro-dependent growth catalysts. We are emphasizing firms that we believe are capable of compounding their earnings growth even in an environment of slower global economic growth. These firms have established global footprints, high quality assets, strong balance sheets, solid top-line growth and an ability to gain market share.

Notes to Financial Statements – Columbia Marsico International Opportunities Fund
February 29, 2012

Note 1. Organization

Columbia Marsico International Opportunities Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class I, Class R and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are only available to qualifying institutional investors.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange

Columbia Marsico International Opportunities Fund, February 29, 2012

rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

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.

(Ameriprise Financial), is responsible for the ultimate oversight of investments made by the Fund. The primary responsibility for the day-to-day portfolio management of the Fund is provided by the Fund's subadviser (see Subadvisory Agreement below). The Management fee is an annual fee that is equal to 0.80% of the Fund's average daily net assets.

* For purposes of the calculation, "Assets" are aggregate assets of the Fund and other affiliated funds managed by the Investment Manager and sub-advised by Marsico Capital Management, LLC.

For the year ended February 29, 2012, no management fees were waived for the Fund.

Subadvisory Agreement

Administration Fees

Pricing and Bookkeeping Fees

Columbia Marsico International Opportunities Fund, February 29, 2012

based on an annualized percentage rate of average daily net assets of the Fund for the month. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective July 11, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Compensation of Board Members

Compensation of Chief Compliance Officer

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

Class A	0.19	%
Class B	0.18
Class C	0.19

Columbia Marsico International Opportunities Fund, February 29, 2012

Note 4. Federal Tax Information

For the Year Ended February 29, 2012, these differences are primarily due to differing treatment for deferral/reversal of wash sales, passive foreign investment companies (PFIC) adjustments, post-October losses, foreign currency transactions, recognition of unrealized appreciation (depreciation) for certain derivative investments, net operating loss reclassifications, and capital loss carryforward. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Excess of distributions over net investment income	$	9,345,735
Accumulated net realized loss		7,846,260
Paid-in capital		(17,191,995	)

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

The tax character of distributions paid during the years indicated was as follows:

	Year ended February 29,		Year ended February 28,
	2012		2011
Ordinary income	$	—	$	19,278,077

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	—
Undistributed accumulated long-term gain		—
Unrealized appreciation		101,411,633

At February 29, 2012, the cost of investments for federal income tax purposes was $506,210,575 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	107,544,632
Unrealized depreciation	$	(6,135,351	)
Net unrealized appreciation/depreciation	$	101,409,281

Year of Expiration	Amount
2017	$	289,767,420
2018		420,548,594
Total	$	710,316,014

Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. However,

Columbia Marsico International Opportunities Fund, February 29, 2012

management's conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

For the year ended February 29, 2012, $58,117,110 of capital loss carryforward was utilized.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $725,288,704 and $1,207,621,207, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

Pursuant to the Agreement, the Fund receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses Net income earned from securities lending for the year ended February 29, 2012 is disclosed in the Statement of Operations. The Fund continues to earn and accrue interest and dividends on the securities loaned.

income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2010 through July 10, 2011, these credits reduced total expenses by $11.

Note 8. Affiliated Money Market Fund

Note 9. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned an aggregate of 63.0% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund.

Note 10. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 11, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 11, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 12. Subsequent Events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than noted below, there were no items requiring adjustment of the financial statements or additional disclosure. On March 8, 2012, an unaffiliated shareholder of the Fund redeemed $68,759,536, which represented approximately 12% of the Fund's net assets as of that date.

Note 13. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and ruled in a case captioned Jones v. Harris Associates, which involves issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

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 Marsico International Opportunities Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent provide a reasonable basis for our opinion.

Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund's independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –1.75% without sales charge. The fund's benchmark, the Russell Midcap Value Index, returned 1.45%. The fund remained focused on attractively valued stocks where we see the potential for improvement in operating margins. However, stock selection hampered results versus the index in a year where macro concerns moved the market.

More volatility for stocks

Although equity market returns were modestly positive, the year was volatile. Headwinds began last spring with a tsunami and earthquake disaster in Japan, an uprising in the Arab world and accelerating sovereign debt problems in Europe. Stocks were further pressured over the summer by concerns over an economic slowdown in China and, in the United States, by sluggish economic growth, the federal budget debacle and an historic federal government credit rating downgrade. Stocks plunged in the third quarter, with the Russell MidCap Value Index declining 18.5%. The market began a sustained rally in October, as recession fears eased and Europe began taking steps to address its issues. The Russell index returned 13.4% in the fourth quarter and continued to gain in the first few months of 2012. In a year that favored companies with stable businesses and high yields, larger-cap stocks beat smaller caps, and more defensive areas, such as consumer staples and utilities, outpaced more economically sensitive sectors, including industrials, materials and energy.

Disappointing results in industrials and consumer staples

Stock selection in the industrials sector was the biggest detractor from relative performance. Our emphasis on construction and engineering companies, including Foster Wheeler (position eliminated), detracted from performance as investors began fearing that slowing global economic growth would dampen government spending on infrastructure projects. An underweight and disappointing stock selection in the consumer staples sector also had a negative impact. Detractors there included an underweight in tobacco company Lorillard (0.5% of net assets), whose outperformance was driven by continued solid fundamentals in its core business, as well as diminishing concerns over the likelihood of a ban on menthol cigarettes. The fund continues to hold a position in Lorillard. Elsewhere, disappointments included coal producer Peabody Energy (0.5% of net assets) within energy, injectable drug manufacturer Hospira (position eliminated) within health care and life insurer Lincoln National (position eliminated) within financials. Peabody's stock sank due to competition from low natural gas prices, while shares of Hospira tumbled when quality control problems surfaced at its plants. We sold Hospira before period end. Lincoln National's stock fell as low interest rates hurt its investment portfolios. An underweight in the more defensive utilities sector further eroded relative results.

Portfolio Managers' Report (continued) – Columbia Mid Cap Value Fund

Positive contribution from consumer discretionary and financials

Investments in the consumer discretionary sector, particularly among specialty and multi-line retailers, aided relative performance. Standouts included athletic apparel retailer Foot Locker (1.3% of net assets), whose strong sales, dividend increase and expanded stock repurchase program attracted investors. An underweight in the weak performing financials sector aided results, as did positive stock selection. Winners included credit card issuer Discover Financial Services (1.1% of net assets), whose stock benefited from growing market share, declining credit costs and an increase in consumer spending in the second half of the year. Elsewhere, top contributors included Cabot Oil and Gas (0.3% of net assets), an independent oil and gas company, whose sharp rally was fueled by accelerating production growth, higher well productivity and increased investor interest in Marcellus Shale (position eliminated). Shares of Equity Residential (position eliminated), an apartment real estate investment trust, climbed nicely, as growing demand for apartment rentals and the company's relatively strong dividend attracted investors.

Positioned for more market volatility

We remain cautiously optimistic that the past year's macro concerns will ease. However, we expect some of these headwinds to linger, which could be a source of future market volatility. For that reason, the fund ended the period with less exposure to economically sensitive areas than it had a year earlier. We are optimistic about prospects for value stocks, which lagged growth stocks over the past year. Going forward, we remain focused on attractively valued securities issued by companies whose operating margins appear to have bottomed and seem ripe for incremental improvement.

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

Stocks of mid-cap companies pose special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor. If the manager's assessment of a company's prospects is wrong, the price of its stock may not approach the value the manager has placed on it.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Columbia Mid Cap Value Fund, February 29, 2012

of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Repurchase Agreements

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

Corporate actions and dividend income are recorded net of any non-reclaimable tax withholdings on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for Return of Capital sales basis adjustment, non-deductible merger expense, proceeds from litigation settlements, capital loss carryforwards, Trustees' deferred compensation and deferral/reversal of wash sale losses. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Undistributed net investment income	$	105,911
Accumulated net realized loss		929,746
Paid-in capital		(1,035,657	)

Columbia Mid Cap Value Fund, February 29, 2012

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

The tax character of distributions paid during the years indicated was as follows:

Year ended February 29,				2012				2011
Ordinary income				$	29,434,025			$	57,327,237

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	1,844,299
Undistributed accumulated long-term gain		—
Unrealized appreciation		695,865,015

At February 29, 2012, the cost of investments for federal income tax purposes was $4,235,597,592 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	808,827,694
Unrealized depreciation	$	(112,962,679	)
Net unrealized app/depreciation	$	695,865,015

The following capital loss carry forward, determined at February 29, 2012, 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				Amount
2018				$	304,313,399

Columbia Mid Cap Value Fund acquired unrealized capital gains as a result of the merger with Riversource Disciplined Small & Mid Cap Equity Fund (Note 12). Due to the acquisition of unrealized capital gains the yearly utilization of the Fund's capital loss carryforward may be limited by the Internal Revenue Code.

For the year ended February 29, 2012, $332,777,382 of capital loss carryforward was utilized.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $1,711,522,372 and $2,647,848,434, respectively, for the year ended February 29, 2012. Transactions to realign the Fund's portfolio following the merger as described in Note 12 are excluded for purposes of calculating the Fund's portfolio turnover rate. These realignment transactions amounted to cost of purchases and proceeds from sales of $107,716,147 and $116,980,620, respectively.

Note 6. Regulatory Settlements

During the year ended February 29, 2012, the Fund received payments of $236,136 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds

Columbia Mid Cap Value Fund, February 29, 2012

from regulatory settlements" in the Statement of Changes in Net Assets.

During the year ended February 28, 2011, the Fund received payments of $17,400 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Note 7. Lending of Portfolio Securities

Effective March 28, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

At February 29, 2012, securities valued at $862,324,180 were on loan, secured by cash collateral of $887,504,518 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Prior to March 28, 2011, the Fund participated in a securities lending arrangement with State Street. Each security on loan was collateralized in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, was paid to the Fund.

Note 8. Custody Credits

Prior to March 28, 2011, the Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through March 27, 2011, there were no custody credits.

Note 9. Affiliated Money Market Fund

Effective March 28, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as "Dividends from affiliates" in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Columbia Mid Cap Value Fund, February 29, 2012

Note 10. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned an aggregate of 32.0% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts of these accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on March 28, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period March 28, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Prior to March 28, 2011, the Fund and certain other funds managed by the Investment Manager participated in a $280 million committed, unsecured revolving credit facility provided by State Street. Interest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 12. Fund Merger

At the close of business on June 3, 2011, the Fund acquired the assets and assumed the identified liabilities of RiverSource Disciplined Small & Mid Cap Equity Fund, a series of RiverSource Dimensions Series, Inc. The reorganization was completed after shareholders of RiverSource Disciplined Small & Mid Cap Equity Fund approved the plan on February 15, 2011. The purpose of the transaction was to combine two funds managed by the Investment Manager with comparable investment objectives and strategies.

The aggregate net assets of the Fund immediately before the acquisition were $4,928,664,500 and the combined net assets immediately after the acquisition were $5,047,066,356.

The merger was accomplished by a tax-free exchange of 15,504,454 shares of RiverSouce Disciplined Small & Mid Cap Equity Fund valued at $118,401,856 (including $19,533,720 of unrealized appreciation).

In exchange for RiverSource Disciplined Small & Mid Cap Equity Fund shares, Columbia Mid Cap Value Fund issued the following number of shares:

	Shares
Class A		764,899
Class B		52,469
Class C		21,768
Class I		262,588
Class R4		681
Class W		7,276,910

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, RiverSource Disciplined Small & Mid Cap Equity Fund's cost of investments was carried forward.

The financial statements reflect the operations of the Fund for the period prior to the merger and the combined fund for the

Columbia Mid Cap Value Fund, February 29, 2012

period subsequent to the merger. Because the combined investment portfolios have been managed as a single integrated portfolio since the merger was completed, it is not practicable to separate the amounts of revenue and earnings of RiverSource Disciplined Small & Mid Cap Equity that have been included in the combined Fund's Statement of Operations since the merger was completed.

Assuming the merger had been completed on March 1, 2011, the Fund's pro-forma net investment income, net gain on investments, net change in unrealized depreciation and net decrease in net assets from operations for the year ended September 29, 2012 would have been approximately $37.0 million, $343.4 million, $(529.2) million and $(148.8) million, respectively.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Mid Cap Value 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 Mid Cap Value Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares and 1.00% for Class C shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would have been lower.

All results shown assume reinvestment of distributions. Class I shares, Class R4 shares, Class Y shares and Class Z shares are sold at net asset value with no distribution and service (12b-1) fees. Class R shares are sold at net asset value with a distribution (12b-1) fee. Class W shares are sold at net asset value with a service (Rule 12b-1) fee. Class I shares, Class R shares, Class R4 shares, Class W shares, Class Y shares and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

Understanding Your Expenses – Columbia Multi-Advisor International Equity Fund

Analyzing your fund's expenses

To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Portfolio during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the "Hypothetical" column assumes a 5% annual rate of return before expenses (which is not the Portfolio's actual return) and then applies the Fund's actual expense ratio for the period to the hypothetical return. 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 the period. See "Compare with other funds" below for details on how to use the hypothetical data.

In addition to the ongoing expenses which the Fund bears directly, the Fund's shareholders indirectly bear the Fund's allocable share of the costs and expenses of each underlying fund in which the Fund invests. You can also estimate the effective expenses paid during the period, which includes the indirect fees associated with investing in the underlying funds, by using the amounts listed in the effective expenses paid during the period column.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –6.26% without sales charge. The fund's benchmark, the MSCI EAFE Index (Net), returned –7.45%. Amid great volatility in the capital markets, the fund held up better than its EAFE benchmark as increased exposure to emerging market and Asia-Pacific opportunities proved successful when markets rallied late in the period. Emerging markets, and many of the Asia-Pacific stocks in the portfolios, are not included in the index.

Europe's debt crisis weighed on foreign stock markets

Stock markets that are highly exposed to the European sovereign debt crisis endured turmoil during the 12-month period. Tensions over European government debt eased somewhat in the final months of the period, following interventions by the European Central Bank, and overseas markets recovered somewhat, led by a robust surge in emerging markets. Despite this late recovery, many international equity benchmarks still produced negative returns for the 12 months.

Fund gained tactical flexibility with revised strategy

Less than three months into the period, the investment team implemented a revised strategy. The fund was divided into four thematic sub-portfolios, three of which centered on a geographic region—Europe, emerging markets and Asia-Pacific—and a fourth on international multi-cap stocks. Threadneedle manages the European portfolio. Columbia manages the emerging markets and Asia-Pacific portfolios. Marsico manages the international multi-cap portfolio, which has exposure to securities from all regions and companies of all sizes. The revised strategy also includes an active currency component managed by Columbia, which gives the fund the potential to invest in currency contracts to take advantage of changes in relative currency values. This increased flexibility to reposition investments tactically, especially in emerging and Asia-Pacific markets, helped the fund minimize losses as those markets rallied late in the period. The fund's currency exposure also helped support results.

Individual stocks also made a positive contribution to return, led by Samsung Electronics of South Korea in the information technology sector and Anheuser Busch/Inbev, the Belgium-based brewer (1.6% and 1.8% of net assets, respectively). Some of the fund's more defensive holdings, notably food products company Nestle and pharmaceutical companies Novartis and Roche (2.5%, 0.4% and 0.5% of net assets, respectively), held back results. All three are Switzerland-based global companies.

European Portfolio

In the Threadneedle-managed portion of the fund, investments in German automobile companies BMW and Volkswagen (1.3% and 0.6% of net assets, respectively) benefitted the fund's performance in Europe, which also was helped by exposure to the French aerospace industry. The de-emphasis of European commercial banks,

Portfolio Manager's Report (continued) – Columbia Multi-Advisor International Equity Fund

especially in Spain, was an effort to mitigate the effects of the European sovereign debt crisis. However, an overweight in Norway, notably in commercial banks, proved to be detrimental to results.

International Multi-Cap Portfolio

In the Marsico-managed portion of the fund, stock selection in industrials and technology companies aided performance. However, an overweight in technology partially offset the benefit of these gains as the sector was an underperformer for the period.

Stock selection in consumer discretionary and energy hurt performance. However, an underweight in financials, utilities and materials sectors aided results, as all three underperformed. Underweights in consumer staples and health care detracted from results, as both sectors were strong performers. Currency fluctuations were an additional source of underperformance for the portfolio during the period, primarily the result of an appreciating yen, which hurt Japanese yen-denominated holdings that were partially hedged into U.S. dollars.

Asia-Pacific Portfolio

An overweight in Thailand supported results in the Asia-Pacific portfolio, managed by Columbia. A position in Total Access, a Thai wireless telecommunications provider (0.05% of net assets) delivered solid gains. Selections in South Korea also helped, notably in Samsung Electronics and in the chemical industry. However, a decision to underweight Japanese heavy equipment manufacturer Komatsu detracted from the fund's performance relative to the benchmark.

Emerging Markets Portfolio

Emphasis on Brazil, combined with a decision to de-emphasize Brazilian oil and natural gas giant Petrobras, had a positive impact in the emerging markets portfolio, managed by Columbia. An overweight in Thailand also helped, especially in financials selections. Stock-picking in the Russian metals and mining industry contributed to holding back results.

Currency component

The fund uses long and short positions in an attempt to take advantage of potential return opportunities in the highly liquid market for currencies of larger developed countries. During the period, currency made a positive contribution to return.

Looking ahead to a year of transition

We anticipate that 2012 will be a year of change. Global growth is not likely to benefit from government austerity programs in the United States and Europe or by the efforts by both financial corporations and individual households to reduce their indebtedness. On the positive side, we believe many corporations have shown signs of improved profitability and appear to be in improving financial condition. Analyzing the risks and

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments, including investment values that may fall, sometimes rapidly or unpredictably, or fail to rise.

Investing in emerging markets may involve greater risks than investing in more developed countries. In addition, concentration of investments in a single region may result in greater volatility.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result

Columbia Multi-Advisor International Equity Fund, February 29, 2012

of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Futures and options on futures contracts are valued based upon the settlement price established each day by the board of trade or exchange on which they are traded.

Foreign Currency Transactions and Translation

Derivative Instruments

Columbia Multi-Advisor International Equity Fund, February 29, 2012

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are agreements between two parties to buy and sell a currency at a set price on a future date. These contracts are intended to be used to minimize the exposure to foreign exchange rate fluctuations during the period between the trade and settlement dates of the contract. The Fund entered into forward foreign currency exchange contracts to facilitate the settlement of purchases and sales of securities and to hedge the currency exposure associated with some or all of the Fund's securities.

Futures Contracts

Futures contracts represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. Upon entering into futures contracts, the Fund bears risks which may include interest rates, exchange rates or securities prices moving unexpectedly, in which case, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Upon entering into a futures contract, the Fund pledges cash or securities with the broker in an amount sufficient to meet the initial margin requirement. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management

The Fund is a "multi-manager" fund. Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager or Columbia), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), is responsible for the ultimate oversight of investments made by the Fund. The primary responsibility for the day-to-day portfolio management of the Fund is provided by the Fund's subadvisers (see Subadvisory Agreement below) and by Columbia, for the portion of the Fund which it manages. Effective April 1, 2011, the management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.79% to 0.62% as the Fund's net assets increase. Prior to April 1, 2011, the management fee was equal to a percentage of the Fund's average daily net assets that declined from 0.70% to 0.51% as the Fund's net assets increased. The effective management fee rate for the year ended February 29, 2012 was 0.72% of the Fund's average daily net assets.

Fund Average Daily Net Assets*	Management Fee Waiver
Assets up to $6 billion		0.00	%
Assets in excess of $6 billion and up to $10 billion		0.05
Assets in excess of $10 billion		0.10

* For purposes of the calculation, "Assets" are aggregate assets of the Fund and other affiliated funds managed by the Investment Manager and sub-advised by Marsico Capital Management, LLC (Marsico).

For the year ended February 29, 2012, no management fees were waived for the Fund.

Subadvisory Agreement

The Investment Manager has entered into Subadvisory Agreements with Marsico Capital Management (MCM Marsico) and Threadneedle International Limited (TI or Threadneedle), each of which subadvises a portion of the assets of the Fund. New investments in the Fund, net of any redemptions, are allocated in accordance with the Investment Manager's determination, subject to the oversight of the Board, of the allocation that is in the best interests of the shareholders. Each subadviser's proportionate share of investments in the Fund will vary due to market fluctuations. The Investment Manager compensates each subadviser to manage the investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. Effective April 1, 2011, the Fund pays the Fund Administrator an annual fee for administration and accounting services equal to a percentage of the Fund's average daily net assets that declines from 0.08% to 0.05% as the Fund's net assets increase. Prior to April 1, 2011, the administration fee was equal to the annual rate of 0.17% of the Fund's average daily net assets, less the fees that were payable by the Fund as described under the Pricing and Bookkeeping Fees note below. The effective administration fee rate for the year ended February 29, 2012 was 0.08% of the Fund's average daily net assets.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for capital loss carryforward limitations related to ownership changes, deferral/reversal of wash sales, passive foreign investment company (PFIC) holdings, deferral/reversal of post-October losses, foreign currency transactions, proceeds from litigation settlements, and recognition of unrealized appreciation (depreciation) for certain derivative investments. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Undistributed net investment income	$	13,070,219
Accumulated net realized loss		324,505,186
Paid-in capital		(337,575,405	)

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

The tax character of distributions paid during the years indicated was as follows:

				Year ended February 29, 2012				Year ended February 28, 2011
Ordinary income				$	—			$	26,467,205

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	12,682,832
Undistributed accumulated long-term gain		—
Accumulated realized gain/loss		—

Columbia Multi-Advisor International Equity Fund, February 29, 2012

gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	213,706,458
Unrealized depreciation		(33,653,122	)
Net unrealized appreciation	$	180,053,336

Year of Expiration	Amount

Total	$	985,966,289

For the year ended February 29, 2012, capital loss carryforwards of $324,204,292 were permanently lost and $80,631,157 were utilized to offset current year gains.

Columbia Multi Advisor International Equity Fund acquired capital loss carryforwards in connection with the merger with Columbia International Stock Fund, Columbia International Growth Fund, Threadneedle International Opportunity Fund, and Riversource Disciplined International Equity Fund of $218,058,552, $131,115,041, $107,220,365, and $383,816,845 respectively (Note 12). In addition to the acquired capital loss carryforwards, the Fund also acquired unrealized capital gains as a result of the merger. The yearly utilization of the acquired capital loss carryforwards may be limited by the Internal Revenue Code. Any capital loss carryforwards acquired as part of a merger that are permanently lost due to the provisions under the Internal Revenue Code are included as being expired.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $2,107,841,345 and $2,523,100,926, respectively, for the year ended February 29, 2012.

These realignment transactions amounted to cost of purchases and proceeds from sales of $1,078,374,891 and $1,144,467,702, respectively.

Note 6. Regulatory Settlements

During the year ended February 29, 2012, the Fund received $3,493,349 as a result of a settlement of administrative proceedings brought by the Securities and Exchange Commission against an unaffiliated third party relating to market timing and /or late trading of mutual funds. This amount represented the Fund's portion of the proceeds from the settlements (the Fund was not a party to the proceeding). The proceeds received by the Fund were recorded as an increase to additional paid in capital.The payments have been

Columbia Multi-Advisor International Equity Fund, February 29, 2012

included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

During the year ended February 28, 2011 the Fund received payments of $25,379 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Note 7. Lending of Portfolio Securities

Effective March 28, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous securities lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

At February 29, 2012, securities valued at $61,946,678 were on loan, secured by cash collateral of $65,242,251 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Note 8. Custody Credits

Note 9. Affiliated Money Market Fund

Columbia Multi-Advisor International Equity Fund, February 29, 2012

Note 10. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned 53.1% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Affiliated shareholder accounts owned 12.0% of the outstanding shares of the Fund. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on March 28, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period March 28, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Note 12. Fund Merger

At the close of business on April 8, 2011, the Fund acquired the assets and assumed the identified liabilities of RiverSource Disciplined International Equity Fund, Threadneedle International Opportunity Fund, Columbia International Stock Fund and Columbia International Growth Fund (the acquired funds). The reorganization was completed after shareholders approved the plan on February 15, 2011. The purpose of the transaction was to combine certain funds managed by the Investment Manager with comparable investment objectives and strategies.

The aggregate net assets of the Fund immediately before the acquisition were $1,220,172,344 and the combined net assets immediately after the acquisition were $2,509,957,223.

The merger was accomplished by a tax-free exchange of 48,647,948 shares of RiverSource Disciplined International Equity Fund valued at $370,503,572 (including $51,911,561 of unrealized appreciation), 42,719,884 shares of Threadneedle International Opportunity Fund valued at $404,664,438 (including $79,018,855 of unrealized appreciation), 30,636,953 shares of Columbia International Stock Fund valued at $379,467,637 (including $70,789,734 of unrealized appreciation), and 9,357,405 shares of Columbia International Growth Fund valued at $135,149,232 (including $32,859,049 of unrealized appreciation).

In exchange for shares of the acquired funds, the Fund issued the following number of shares:

	Shares
Class A		34,476,734
Class B		1,930,534
Class C		1,792,925
Class I		19,889,124
Class R		166,754
Class R4		14,235
Class W		15,438,672
Class Y		1,172,264
Class Z		27,157,783

Columbia Multi-Advisor International Equity Fund, February 29, 2012

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, RiverSource Disciplined International Equity Fund, Threadneedle International Opportunity Fund, Columbia International Stock Fund and Columbia International Growth Fund's cost of investments was carried forward.

The financial statements reflect the operations of the Fund for the period prior to the merger and the combined fund for the period subsequent to the merger. Because the combined investment portfolios have been managed as a single integrated portfolio since the merger was completed, it is not practicable to separate the amounts of revenue and earnings of RiverSource Disciplined International Equity Fund, Threadneedle International Opportunity Fund, Columbia International Stock Fund and Columbia International Growth Fund that have been included in the combined Fund's Statement of Operations since the merger was completed.

Assuming the merger had been completed on March 1, 2011 the Fund's pro-forma net investment income, net gain on investments, net change in unrealized depreciation and net decrease in net assets from operations for the six months ended August 31, 2011 would have been approximately $35.1 million, $37.2 million, $(286.6) million and $(214.3) million, respectively.

Note 14. Subsequent Events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted below, there were no items requiring adjustment of the financial statements or additional disclosure.

On March 23, 2012, a group of unaffiliated shareholders of the Fund redeemed $239,388,854, which represented approximately 14% of the Fund's net assets as of that date.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Multi-Advisor International 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 Multi-Advisor International Equity Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent, provide a reasonable basis for our opinion.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –0.41% without sales charge. The Russell 2000 Growth Index returned 2.38%. Stock selection within financials had the biggest negative impact on relative performance, followed by security selection in the technology and materials sectors. The fund's sector weights remained close to those in the Russell index.

Year of extreme market volatility

The past year was a challenge for managers who focus on stock selection, as macro events rather than company-specific metrics drove market returns. Stocks got off to a strong start last spring, but were soon shaken by unrest in the Middle East as well as by the reverberations of an earthquake and tsunami disaster in Japan. Heading into the summer, Europe's sovereign debt problems began to accelerate and global economic growth slowed, pressuring returns. Congress's wrangling about the U.S. federal budget deficit and Standard & Poor's historic downgrade of the country's credit rating further unsettled the market, leading to a steep decline in the third quarter of 2011.

Economically-sensitive sectors and small-cap stocks were among the hardest hit during this period. In October, the stock market began a turnaround, buoyed by signs of improving U.S. economic growth and progress in Europe. Stocks continued to climb into the new year, as substantial new job creation, declining headline inflation and an increase in manufacturing activity encouraged investors. Large-cap stocks came out ahead of small cap for the year; and in an environment of scarce earnings growth, growth stocks outpaced value.

Biggest disappointments from financials and technology sectors

The fund lost the most ground versus the Russell index from investments in the financials sector, although no one stock stood out as a leading detractor. Stock picks in information technology and materials also hampered performance. In technology, shares of BroadSoft (position eliminated), whose software enables telecommunications and cable providers to deliver voice and multimedia services over Internet protocol-based networks, fell sharply after the company lowered its pricing to gain market share and ended up with a revenue shortfall. In the materials sector, disappointments included Stillwater Mining, a palladium and platinum miner whose shares declined as investors began anticipating higher costs and slower economic growth. We sold the stake before period end. Elsewhere, detractors included snack food maker Diamond Foods (position eliminated) in the consumer staples sector and independent oil and gas producer Magnum Hunter Resources (0.02% of net assets) within energy. Shares of Diamond Foods tumbled as questions over its accounting practices derailed a planned acquisition, while Magnum's stock suffered from an earnings miss late in the period.

Portfolio Managers' Report (continued) – Columbia Small Cap Growth Fund II

Gains from industrials and consumer discretionary

Stock selection in the industrials and consumer discretionary sectors helped performance relative to the Russell index. While no one industrials stock was a top contributor, several consumer discretionary stocks were noteworthy. They included Tempur-Pedic International, Pier 1 Imports and Polaris Industries (1.3%, 1.1% and 0.6% of net assets, respectively). The stock of premium bedding manufacturer Tempur-Pedic, which is not included in the benchmark, produced sharp gains, buoyed by the popularity of the company's new Cloud mattresses and a vigorous marketing campaign. Shares of specialty retailer Pier I were lifted by better-than-expected revenues and earnings. The stock of Polaris, which designs, engineers and manufactures off-road vehicles, saw steep gains, as strong earnings, a successful acquisition and a dividend increase attracted investors. Elsewhere, an investment in HMS Holdings (1.6% of net assets), a company that helps eliminate fraud and abuse in the health care system, climbed sharply after a recent acquisition gave the firm a stronghold on both Medicare and Medicaid audits.

Cautious outlook

At period end, the portfolio was positioned to benefit from a modestly expanding economic environment as well as slightly higher employment numbers. While we believe the odds of recession have been reduced, we nevertheless expect 2012 economic growth to be lower than its long-term trend. With that backdrop in mind, we plan to focus the fund on companies whose earnings growth is not dependent on the economy; businesses that are expanding their profit margins and market share and firms whose products and services can command premium pricing.

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

Stocks of small-cap companies pose special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Notes to Financial Statements – Columbia Small Cap Growth Fund II
February 29, 2012

Note 1. Organization

Columbia Small Cap Growth Fund II (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class I and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Effective April 29, 2011, the Fund is closed to new investors and new accounts, subject to certain limited exceptions.

On December 8, 2011, an affiliated fund of funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), exchanged Class Z shares valued at $11,149,900 for Class I shares.

Class B shares may be subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will generally convert to Class A shares eight years after purchase.

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds. Class I shares commenced operations on November 16, 2011.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange

Columbia Small Cap Growth Fund II, February 29, 2012

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Foreign Currency Transactions and Translation

Repurchase Agreements

Security Transactions

Income Recognition

Corporate actions and dividend income are recorded on the ex-dividend date.

Interest income is recorded on the accrual basis.

Columbia Small Cap Growth Fund II, February 29, 2012

Expenses

Determination of Class Net Asset Value

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 (including net short-term capital gains), 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 from net investment income are declared and paid annually. Net realized capital gains, if any, are distributed along with the income dividend. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations which may differ from GAAP.

Guarantees and Indemnifications

Fair Value Measurements and Disclosures

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, the Investment Manager determines which securities will be purchased, held or sold. The management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.70% to 0.60% as the Fund's net assets increase. The effective management fee rate for the

Columbia Small Cap Growth Fund II, February 29, 2012

year ended February 29, 2012 was 0.70% of the Fund's average daily net assets.

Administration Fees

Pricing and Bookkeeping Fees

Prior to June 27, 2011, the Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Fund. The Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Fund. Under the State Street Agreements, the Fund paid 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. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective June 27, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Compensation of Board Members

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

Columbia Small Cap Growth Fund II, February 29, 2012

reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A	0.19	%
Class B	0.19
Class C	0.19
Class Z	0.19

Distribution and Service Fees

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also require the payment of a monthly service fee at the maximum annual rate of 0.25% of the average daily net assets attributable to Class B and Class C shares of the Fund and the payment of a monthly distribution fee at the maximum annual rate of 0.75% of the average daily net assets attributable to Class B and Class C shares of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $10,949 for Class A, $820 for Class B, and $6 Class C shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Class A	1.35	%
Class B	2.10
Class C	2.10
Class I	0.97
Class Z	1.10

Columbia Small Cap Growth Fund II, February 29, 2012

Prior to July 1, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund's expenses (excluding certain expenses, such as distribution and services fees, brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund's ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, did not exceed 1.10% of the Fund's average daily net assets on an annualized basis.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for net operating losses, deferral/reversal of wash sales, passive foreign investment company (PFIC) holdings, capital loss carryforwards, deferred trustees expense, proceeds from litigation settlements, foreign currency translations and late year ordinary losses. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Excess of distributions over net investment income	$	1,999,058
Accumulated net realized loss		(208,548	)
Paid-in capital		(1,790,510	)

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

For the years ended 2012 and 2011, there were no distributions.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	—
Undistributed accumulated long-term gain		—
Unrealized appreciation		40,587,895

At February 29, 2012, the cost of investments for federal income tax purposes was $280,892,865 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	48,503,069
Unrealized depreciation		(7,915,174	)
Net unrealized appreciation	$	40,587,895

Year of expiration				Amount
	2018			$	32,560,524

Columbia Small Cap Growth Fund II, February 29, 2012

As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused.

Note 6. Regulatory Settlements

During the year ended February 29, 2012, the Fund received payments of $950,234 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Note 7. Lending of Portfolio Securities

Effective June 27, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. For the year ended February 29, 2012, the Fund did not participate in securities lending activity.

Pursuant to the Agreement, the Fund receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses. The Fund continues to earn and accrue interest and dividends on the securities loaned.

Columbia Small Cap Growth Fund II, February 29, 2012

Prior to June 27, 2011, the Fund participated in a securities lending arrangement with State Street. Each security on loan was collateralized in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, was paid to the Fund.

Note 8. Custody Credits

Prior to June 27, 2011, the Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through June 26, 2011, these credits reduced total expenses by $5.

Note 9. Affiliated Money Market Fund

Effective June 27, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as "Dividends from affiliates" in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 10. Shareholder Concentration

At February 29, 2012, one unaffiliated shareholder account owned 42.5% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on June 27, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period June 27, 2011 through December 12, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

For the period May 16, 2011 through June 26, 2011, the Fund and certain other funds managed by the Investment Manager participated in a $150 million committed, unsecured revolving credit facility provided by State Street. For the period March 28, 2011 through May 15, 2011, the collective borrowing amount of the credit facility was $225 million. Prior to March 28, 2011, the collective borrowing amount of the credit facility was $280 million. Interest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Small Cap Growth Fund II

In our opinion, the accompanying statement of assets and liabilities, including the investment portfolio, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Columbia Small Cap Growth Fund II (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the 12-month period that ended February 29, 2012, the fund's Class Z shares returned –6.17%. The fund's benchmark, the MSCI EAFE Value Index (Net), returned –9.85%. In a period during which foreign stocks produced generally weak results, stock selection helped minimize the fund's losses. An underweight in financial and utility stocks also aided returns.

Europe's debt crisis weighed on foreign stock markets

Stock markets that are highly exposed to the European sovereign debt crisis endured turmoil during the 12-month period. Tensions over European government debt eased somewhat in the final months of the period, following interventions by the European Central Bank, and overseas markets recovered somewhat, led by a robust surge in emerging markets. Despite this late recovery, most international equity benchmarks still produced negative returns for the 12 months.

Sector allocations, stock selection drove results

As debt problems in Europe proved to be the single most powerful drag on the markets, a decision to underweight financials stocks, especially European banks, supported relative results. The fund's modest exposure to utilities also helped as the group was plagued by worries about nuclear safety following the meltdown of the plant owned by Tokyo Electric Power (TEPCO). The fund held no investment in TEPCO. By country, an out-of-benchmark investment in U.S.-based stocks was positive for returns. We held U.S. stocks because we believed it had dealt more successfully with banking industry problems than had European nations. In addition, relative performance was aided by underweights relative to the benchmark in the United Kingdom and Japan and lack of exposure to Greece.

Certain individual securities made positive contributions to return. South Korean consumer apparel manufacturer Youngone Corp. was well positioned to benefit when wage inflation in China encouraged clothing companies to look elsewhere. Youngone Corp., which maintained its manufacturing base in low-cost Bangladesh, benefited from this movement. While we sold the position in Youngone Corp. to take profits, we retained an interest by establishing a stake in Youngone Holdings (1.0% of net assets), which is an investor in Youngone Corp., and whose stock price looked more attractive. Hyundai Home Shopping (1.1% of net assets), a Korean television shopping network whose upscale products attract customers in Korea's expanding middle class, also delivered a solid return. Hyundai Home Shopping's buying relationship with former parent firm Hyundai Department Stores gave the network a competitive advantage in bargaining with suppliers. Electromagnetic GeoServices (0.8% of net assets), a Norwegian energy service firm involved in deepwater oil and gas exploration, was another solid performer. The company is the world's leading supplier of a sophisticated technology that produces three-dimensional maps of underwater oil and gas deposits, increasing the efficiency and effectiveness of underwater energy exploration activities.

Portfolio Managers' Report (continued) – Columbia Overseas Value Fund

Consumer, agricultural products disappointed

Pandora, a Danish costume jewelry company, was a noteworthy disappointment. Pandora's charm bracelets had been a major driver of growth, but the company had no adequate replacement when fashion fads changed. We sold the position in Pandora. Asian Citrus (0.7% of net assets), the largest citrus fruit producer in China, was another significant disappointment. The company was dragged down in a controversy surrounding two other companies involved in agricultural or forest products in China. However, we believe that Asian Citrus stock had been unfairly punished, and we retained the position because we liked its long-term growth potential.

Looking ahead

We have positioned the fund conservatively, placing even more emphasis on companies that we believe have shown consistent ability to produce stable cash flows and that maintain solid balance sheets and relatively little debt. We have taken a conservative stance even though we see some encouraging developments in the global economy. Leading indicators are increasingly positive for both U.S. and European economies, while generally accommodative central bank monetary policies support economic expansion.

However, the market rally of the first two months of 2012 may mean that most of the favorable economic news already is reflected in stock prices. And, we believe the European sovereign debt crisis is not over. The European Central Bank may have addressed worries about financial liquidity, but governments still have not resolved the underlying political and fiscal issues that caused the crisis.

Given these concerns, we have de-emphasized European investments and have underweighted highly cyclical stocks that are dependent on robust economic growth. We intend to keep the fund conservatively positioned until we see concrete evidence of change.

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

Investing in emerging markets may involve greater risks than investing in more developed countries. In addition, concentration of investments in a single region may result in greater volatility.

Value stocks are securities of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor. If the manager's assessment of a company's prospects is wrong, the price of the company's stock may not approach the value the manager has placed on it.

Notes to Financial Statements – Columbia Overseas Value Fund
February 29, 2012

Note 1. Organization

Columbia Overseas Value Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class I, Class W and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

The Fund is authorized to issue Class A and Class C shares, which would be subject to sales charges, and Class R shares, which would not be subject to sales charges; however these share classes are not currently offered for sale and have not commenced operations.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds. Class I shares commenced operations on March 31, 2011.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Columbia Overseas Value Fund, February 29, 2012

Short-term securities maturing in more than 60 days from the valuation date are valued at the market price or approximate market value based on current interest rates.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Futures and options on futures contracts are valued based upon the settlement price established each day by the board of trade or exchange on which they are traded.

Option contracts are valued at the mean of the latest quoted bid and asked prices on their primary exchanges. Option contracts, including over-the-counter (OTC) option contracts, with no readily available market value are valued using quotations obtained from independent brokers as of the close of the NYSE.

Forward Foreign Currency Exchange Contracts

Columbia Overseas Value Fund, February 29, 2012

exchange to shift investment exposure from one currency to another.

Futures Contracts

Futures contracts represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund sold currency futures contracts to offset the fund's active currency exposures back to the benchmark. Upon entering into futures contracts, the Fund bears risks which may include interest rates, exchange rates or securities prices moving unexpectedly, in which case, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Options

Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. The Fund wrote covered call and purchased put options to decrease the Fund's exposure to equity risk and to increase return on instruments. Completion of transactions for option contracts traded in the OTC market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain OTC option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the counterparty or the Fund upon closure, exercise or expiration of the contract.

Option contracts purchased are recorded as investments and options contracts written are recorded as liabilities of the Fund. The Fund will realize a gain or loss when the option contract expires or is exercised. When option contracts on debt securities or futures are exercised, the Fund will realize a gain or loss. When other option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.

The risk in buying an option contract is that the Fund pays a premium whether or not the option contract is exercised. The Fund also has the additional risk of being unable to enter into a closing transaction if a liquid secondary market does not exist. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases and the option contract is exercised. The Fund's maximum payout in the case of written put option contracts represents the maximum potential amount of future payments (undiscounted) that the Fund could be required to make under the contract. For OTC options contracts, the transaction is also subject to counterparty credit risk. The maximum payout amount may be offset by the subsequent sale, if any, of assets obtained upon the exercise of the put option contracts by holders of the option contracts or proceeds received upon entering into the contracts.

Columbia Overseas Value Fund, February 29, 2012

Contracts and premiums associated with options contracts written for the year ended February 29, 2012 are as follows:

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), determines which securities will be purchased, held or sold. Effective July 1, 2011, the management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.79% to 0.62% as the Fund's net assets increase. Prior to July 1, 2011, the management fee was equal to the annual rate of 0.82% of the Fund's average daily net assets. The effective management fee rate for the year ended February 29, 2012 was 0.80% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. Effective July 1, 2011, the Fund pays the Fund Administrator an annual fee for administration and accounting services equal to a percentage of the Fund's average daily net assets that declines from 0.08% to 0.05% as the Fund's net assets increase. Prior to July 1, 2011, the administration fee was equal to the annual rate of 0.05% of the Fund's average daily net assets, less the fees that were payable by the Fund as described under the Pricing and Bookkeeping Fees note below. The effective administration fee rate for the year ended February 29, 2012 was 0.07% of the Fund's average daily net assets.

Pricing and Bookkeeping Fees

Columbia Overseas Value Fund, February 29, 2012

based on an annualized percentage rate of average daily net assets of the Fund for the month. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective June 27, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Compensation of Board Members

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class W					0.02	%
Class Z					0.06

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the Fund's initial minimum investment requirements to reduce the impact of small accounts on transfer agent fees. These minimum account balance fees are recorded as part of expense reductions in the Statement of Operations. For the year ended February 29, 2012, no minimum account balance fees were charged by the Fund.

Columbia Overseas Value Fund, February 29, 2012

Distribution and Service Fees

The Fund has an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. Pursuant to Rule 12b-1 under the 1940 Act, the Board of Trustees has approved, and the Fund has adopted, a shareholder service plan (the Plan) which set the service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

The Plan requires the payment of a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class W shares of the Fund.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Class I	0.80	%
Class W	1.25
Class Z	1.00

Prior to July 1, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund's expenses (excluding certain expenses, such as any distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund's ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, did not exceed 1.15% of the Fund's average daily net assets.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for Recognition of unrealized appreciation (depreciation) for certain derivative investments, capital loss carryforwards, deferred trustees expense, post-October losses deferral/reversal of wash sales, passive foreign investment company (PFIC) holdings and foreign capital gains tax.

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 Overseas Value Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares and 1.00% for Class C shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower.

Performance results reflect any fee waivers or reimbursements of fund expenses by the Columbia Management Investment Advisers, LLC and/or any of its affiliates. Absent these fee waivers or expense reimbursement arrangements, performance results would have been lower.

All results shown assume reinvestment of distributions. Class R shares are sold at net asset value with a distribution (12b-1) fee. Class Z shares are sold at net asset value with no distribution and service (12b-1) fees. Class R and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

¹Percentages indicated are based upon total investments (excluding Investments of Cash Collateral Received for Securities on Loan). The Fund's portfolio composition is subject to change.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –6.82% without sales charge. The fund underperformed its benchmark, the Russell 3000 Index, which returned 4.45%. Exposure to the weak-performing financials sector was a primary detractor from performance. Underweights in health care and consumer staples also hurt results.

In October 2011 the fund's management changed. Cory Gilchrist left the firm to pursue personal and charitable interests and Brandon Geisler, senior research analyst at Marsico Capital Management, became manager of the fund.

U.S. economy picks up momentum

Sector weights detracted from results relative to the index

During the period, the fund's sector weights, which are largely a result of the stock selection process, detracted from performance relative to the index. The fund had lower-than-benchmark allocations to health care and consumer staples, which performed well during the period. The fund had a greater stake in financials than the benchmark, and financials were weak performers. Stock selection within financials also hurt results. First Horizon National, First Niagara Financial (1.0% and 1.5% of net assets, respectively) and Wells Fargo materially detracted from performance. Diversified financials firm Jefferies Group was also a poor performer. Jefferies and Wells Fargo were sold from the portfolio. As the largest banks and financial institutions face more stringent regulations, we believe that the outlook and earnings visibility for some have deteriorated, and we reduced the fund's exposure to financials during the period. By contrast, the fund benefited from having more exposure than the index to the consumer discretionary sector, which was a strong performer during the period.

Stock selection generated mixed results

Stock selection in the energy and consumer discretionary sectors detracted from results. In energy, oil and gas exploration and production companies OGX Petróleo e Gás Participações S.A. and Ultra Petroleum each posted significant declines prior to being

Portfolio Manager's Report (continued) – Columbia Marsico 21^st Century Fund

sold from the fund. Within consumer discretionary, we sold poor performers General Motors, Walt Disney and fashion retailer Rue21.

In health care, Intuitive Surgical (3.0% of net assets), which makes a robotic system for assisting in minimally invasive surgeries, was among the fund's strongest performing individual positions. Consumer electronics giant Apple, aerospace components company Precision Castparts and retailers Ross Stores and Ulta Salon Cosmetics & Fragrance (5.9%, 2.7%, 3.1% and 1.3% of net assets, respectively) were also notable strong performers.

Looking ahead

It has been a challenging year for the fund. We have taken steps to improve performance by adding more balance and breadth to the fund. In addition to significantly reducing the fund's financials exposure, we increased allocations to the energy, industrials, consumer discretionary and information technology sectors.

Notes to Financial Statements – Columbia Marsico 21^st Century Fund
February 29, 2012

Note 1. Organization

Columbia Marsico 21^st Century Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class R and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange

Columbia Marsico 21^st Century Fund, February 29, 2012

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), is responsible for the ultimate oversight of investments made by the Fund. The primary responsibility for the day-to-day portfolio management of the Fund is provided by the Fund's subadviser (see Subadvisory Agreement below). The management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.75% to 0.56% as the Fund's net assets increase. The effective management fee rate for the year ended February 29, 2012 was 0.66% of the Fund's average daily net assets.

Fund Average Daily Net Assets*	Management Fee Waiver
Assets up to $18 billion		0.00	%
Assets in excess of $18 billion and up to $21 billion		0.05
Assets in excess of $21 billion		0.10

* For purposes of the calculation, "Assets" are aggregate assets of the Fund and other affiliated funds managed by the Investment Manager and sub-advised by Marsico Capital Management, LLC.

For the year ended February 29, 2012, no management fees were waived for the Fund.

expenses. Payment of these Fund and Board expenses is facilitated by a company providing limited administrative services to the Fund and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $8,387.

Compensation of Board Members

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for net operating loss reclassifications, deferral/reversal of wash sales, recognition of unrealized appreciation (depreciation) for certain derivative investments, late year ordinary losses, capital loss carryforward and deferred trustees expense. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Excess of distributions over net investment income	$	8,254,244
Accumulated net realized loss		2,177,929
Paid-in capital		(10,432,173	)

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

For the years ended 2011 and 2012 there were no distributions.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	—
Undistributed accumulated long-term gain		—
Unrealized appreciation		374,386,701

Columbia Marsico 21^st Century Fund, February 29, 2012

At February 29, 2012, the cost of investments for federal income tax purposes was $1,572,718,983 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	390,309,996
Unrealized depreciation		(15,923,295	)
Net unrealized appreciation	$	374,386,701

Year of Expiration	Amount
2017	$	588,195,840
2018		1,526,982,692
Total	$	2,115,178,532

For the year ended February 29, 2012, $67,610,199 of capital loss carryforward was utilized.

Under current tax rules, regulated investment companies can elect to treat certain late-year ordinary losses incurred and post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. As of February 29, 2012, the Fund will elect to treat late year ordinary losses of $1,154,810 as arising on March 1, 2012.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $2,776,799,289 and $4,285,623,421, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

Effective July 11, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $276,279,733 were on loan, secured by cash collateral of $284,722,977 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the

Columbia Marsico 21^st Century Fund, February 29, 2012

securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower's failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Note 7. Custody Credits

Note 8. Affiliated Money Market Fund

Note 9. Shareholder Concentration

At February 29, 2012, one unaffiliated shareholder account owned 15.7% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 10. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 11, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 11, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Marsico 21^st Century 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 Marsico 21^st Century Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned 4.26% without sales charge. The fund's benchmark, the S&P 500 Index, returned 5.12%. Stock selection and an overweight in the consumer discretionary sector aided results, as did a reduction in the fund's stake in the financials sector. However, overall sector allocations detracted from performance, as the fund had lower exposure to the best-performing sectors of the S&P 500. Several energy and materials holdings hurt results as well.

U.S. economy picks up momentum

Sector positioning, stock selection detract

Against this economic backdrop, the fund had few investments in the three strongest-performing sectors of the S&P 500 Index: utilities, consumer staples and health care. This positioning hurt performance. In addition, a number of individual stocks in the energy and materials sectors were disappointing. In the latter, oil field service provider Halliburton (2.7% of net assets) and natural gas and oil firm EOG Resources posted double-digit negative returns. We sold EOG Resources from the portfolio. The prospects of slower global economic growth put downward pressure on the stock prices of many materials companies. Fund holdings Freeport-McMoRan Copper & Gold and Dow Chemical (1.2% and 2.4% of net assets, respectively) both succumbed to steep price declines. In the health care sector, Agilent Technologies, the world's largest test and measurement firm, had a negative return and was sold from the fund.

Stock selection and consumer discretionary exposure positive

Stock selection in the information technology and industrials sectors benefited fund performance. Within information technology, financial transactions processor Visa, Chinese internet search company Baidu and consumer electronics firm Apple (4.0%, 3.6% and 8.2% of net assets, respectively) each appreciated significantly. In industrials, Goodrich, which is among the world's largest suppliers of components and services to the aviation markets, engine company Cummins (3.3% of net assets) and Union Pacific, the largest public railroad in the US (2.9% of net assets) were strong contributors to performance. We sold Goodrich from the portfolio.

Fund results benefited from both an overweight position in the consumer discretionary sector (a strong performer in the S&P 500 Index) and from stock selection in that sector. Specialty coffee retailer Starbucks, restaurant operator Chipotle Mexican Grill

Portfolio Managers' Report (continued) – Columbia Marsico Focused Equities Fund

and online travel reservations company priceline.com (3.7%, 2.1% and 3.4% of net assets, respectively) were notably strong performers.

We viewed the regulatory climate for the financial services sector as becoming considerably more complex and significantly reduced the fund's allocation to the area during the period. This decision aided performance as the sector was the weakest performer in the S&P 500 Index.

Portfolio activity

During the 12-month period, we undertook a number of steps aimed at reducing the fund's emphasis on economically-sensitive companies. We pared exposure to industrials, materials and the commodity complex and pulled back significantly from financial stocks. We increased investments in companies that we believe have durable franchises with dependable revenue streams that we think are capable of compounding their earnings growth even in a choppy economic environment. These companies span a variety of industries but share several common factors, such as an established global footprint, high quality assets, solid top-line unit growth and an ability to gain market share.

Looking ahead

By the end of the period, we sought to position the portfolio to reflect uncertainty in Europe balanced against a more constructive scenario in which the euro zone stabilizes and global growth is reaccelerated. Hence, a number of holdings are more defensive in nature, with business models that have proven to be less susceptible to adverse macroeconomic conditions and with the potential for generating solid top-line growth and dependable revenues. Another segment of the portfolio is represented by cyclical companies that should benefit if the euro zone moves closer to a solution and global economic conditions continue to improve. A final segment of the portfolio consists of stocks selected from a purely bottom-up perspective, which we view as unique stories and compelling investments.

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

The fund normally invests in a core portfolio of 20-30 common stocks. By maintaining a relatively concentrated portfolio, the fund may be subject to a greater risk than a fund that is more fully diversified.

Investing in emerging markets may involve greater risks than investing in more developed countries. In addition, concentration of investments in a single region may result in greater volatility.

Notes to Financial Statements – Columbia Marsico Focused Equities Fund
February 29, 2012

Note 1. Organization

Columbia Marsico Focused Equities Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign

Columbia Marsico Focused Equities Fund, February 29, 2012

exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Foreign Currency Transactions and Translation

Repurchase Agreements

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

Awards from class action litigation are recorded as a reduction of cost if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), is responsible for the management of the Fund. Day-to-day portfolio management of the Fund is provided by the Fund's subadviser. See Subadvisory Agreement below. The Management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.75% to 0.56% as the Fund's net assets increase. The effective management fee rate for the year ended February 29, 2012 was 0.66% of the Fund's average daily net assets.

To the extent that the Fund is not benefitting from a separate contractual expense limitation arrangement, the Investment Manager has contractually agreed to waive a portion of its

Columbia Marsico Focused Equities Fund, February 29, 2012

management fee through June 30, 2012. In the absence of a separate contractual expense limitation arrangement, the management fee waiver for the Fund would be calculated as follows:

Fund average daily net assets*	Management fee waiver
Assets up to $18 billion		0.00	%
Assets in excess of $18 billion and up to $21 billion		0.05
Assets in excess of $21 billion		0.10

* For purposes of the calculation, "Assets" are aggregate assets of the Fund and other affiliated funds managed by the Investment Manager and sub-advised by Marsico Capital Management, LLC.

For the year ended February 29, 2012, no management fees were waived for the Fund.

Compensation of Board Members

Compensation of Chief Compliance Officer

Columbia Marsico Focused Equities Fund, February 29, 2012

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A	0.20	%
Class B	0.20
Class C	0.20
Class Z	0.20

Distribution and Service Fees

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also require the payment of a monthly service fee at the maximum annual rate of 0.25% of the average daily net assets attributable to Class B and Class C shares of the Fund and the payment of a monthly distribution fee at the maximum annual rate of 0.75% of the average daily net assets attributable to Class B and Class C shares of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $173,619 for Class A, $17,505 for Class B and $4,579 for Class C shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Columbia Marsico Focused Equities Fund, February 29, 2012

the following annual rates as a percentage of the class' average daily net assets:

Class A	1.45	%
Class B	2.20

Class Z	1.20

Class A	1.45	%
Class B	2.20
Class C	2.20
Class I	1.08
Class Z	1.20

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for foreign currency transactions, distribution reclassifications, redemption-based payments treated as eligible for the dividends paid deduction, deferral/reversal of wash sale losses and deferred trustees' expense. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Overdistributed net investment income	$	405,546
Accumulated net realized gain		(7,348,913	)
Paid-in capital		6,943,367

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

The tax character of distributions paid during the years indicated was as follows:

Year ended	February 29, 2012		February 28, 2011
Ordinary income*	$	2,759,309	$	1,798,129
Long-term capital gains	$	32,938,581		—

* Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed long-term capital gains				$	119,896,502
Unrealized appreciation					579,934,629

Columbia Marsico Focused Equities Fund, February 29, 2012

At February 29, 2012, the cost of investments for federal income tax purposes was $2,054,719,891 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	603,013,661
Unrealized depreciation	$	(23,079,032	)
Net unrealized appreciation	$	579,934,629

For the year ended February 29, 2012, $118,149,360 of capital loss carryforward was utilized.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $2,215,989,174 and $2,577,183,127, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

Effective July 11, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

At February 29, 2012, securities valued at $129,901,081 were on loan, secured by cash collateral of $133,207,511 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Columbia Marsico Focused Equities Fund, February 29, 2012

services provided and any other securities lending expenses. Net income earned from securities lending for the year ended February 29, 2012 is disclosed in the Statement of Operations. The Fund continues to earn and accrue interest and dividends on the securities loaned.

Note 7. Custody Credits

Note 8. Affiliated Money Market Fund

Note 9. Shareholder Concentration

At February 29, 2012, three unaffiliated shareholder accounts owned an aggregate of 51.0% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 10. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on July 11, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 11, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Columbia Marsico Focused Equities Fund, February 29, 2012

fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 11. Significant Risks

Non-Diversification Risk

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

Foreign Securities Risk

Note 12. Subsequent Events

On March 23, 2012, a group of unaffiliated shareholders of the Fund redeemed $368,803,706, which represented approximately 15% of the Fund's net assets as of that date.

Note 13. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and ruled in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Marsico Focused Equities 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 Marsico Focused Equities Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for the two years in the period then ended and the financial highlights for each of 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.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year, and eliminated thereafter for Class B shares and 1.00% for Class C shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would be lower.

All results shown assume the reinvestment of distributions. Class I and Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class R shares are sold at net asset value with a distribution (12b-1) fee. Class W shares are sold at net asset value with a service (12b-1) fee. Class I, Class R, Class W and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details.

Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned negative 0.75% without sales charge. In a difficult environment, the fund held up better than its benchmark, the Bank of America Merrill Lynch All Convertibles All Qualities Index, which returned negative 1.10%. Successful security selection, led by holdings in the information technology, materials and energy sectors, helped the fund outperform the index during the period.

The U.S. economy picks up momentum

During the first half of the 12-month period, a series of natural disasters in Japan, Europe's debt problems and wrangling in Washington over the federal budget and the national debt dominated world headlines. U.S. economic news was lackluster and job growth was disappointing. However, the pace of growth picked up in the second half of the period and, as fears of a lapse back into recession faded, prospects brightened. Consumer confidence improved even though consumers remain under pressure, with no real increase in disposable income and a continued decline in household net worth. The labor markets added more than a million new jobs from September 2011 through February 2012, and the jobless rate fell to 8.3%. Headline inflation—which tracks a broad range of consumer expenditures, including food and energy—declined. Even manufacturing held its ground. A modest slowdown in manufacturing activity late in the summer of 2011 raised concern that this lynchpin of the recovery was ready to turn downward. However, manufacturing activity stabilized and the manufacturing expansion continued into 2012. Housing continues to be the one nagging weak spot in the economy. Yet, home sales edged modestly higher over the year, and there is hope that a bottom in the housing market is in sight.

Security selection drove results

Against this backdrop, the capital markets, including the convertibles market, endured a challenging and volatile period. Early in the period, convertibles struggled in the face of a host of questions about overall economic prospects. However, investors regained confidence in the closing months of the period and convertibles staged a comeback rally. Over the 12 months, we held to a consistent strategy, pursuing a bottom-up security selection process. Decisions about individual investments were heavily influenced by our professional analysis. Security selection drove returns, and sector weights had no material effect on relative performance.

Technology picks helped lift results

Several investments in convertibles issued by information technology corporations aided the fund's results relative to the index, led by voice recognition software company Nuance Communications and Equinix, operator of a global platform of data centers (1.1% and 1.2% of net assets, respectively). We took profits when software services company RightNow Technologies, a third strong technology performer, announced it was being acquired. In the materials sector, we posted a large profit in Molycorp when the stock price was peaking. We sold Molycorp convertible preferred and reallocated assets into a convertible bond. In energy, notable contributors included services provider Hornbeck Offshore and exploration-and-production firm Energy XXI (1.6% and 0.6% of net assets, respectively).

Portfolio Manager's Report (continued) – Columbia Convertible Securities Fund

Financials and health care holdings included disappointments

The fund's overweight in Citigroup (1.9% of net assets) held back performance when the global bank's stock dived amid intense market concerns about the effects of the sovereign debt crisis in Europe. Other financials holdings that produced disappointments included insurers Hartford Financial and MetLife (0.6% and 1.1% of net assets, respectively). Low interest rates on life and annuity products and heavy casualty losses from natural disasters handicapped insurers generally. Despite these setbacks, we maintained investments in all three companies because we believed they had good recovery potential. In health care, a notable laggard was pharmaceutical company Dendreon (2.3% of net assets). Slower-than-expected revenues from a new prostate cancer drug disappointed investors, but we retained our position because of the company's credit-worthiness and our expectation that the convertible bond should rebound in price as it approaches maturity in 2016.

Recovery in convertibles may continue

We believe the late-period rally in convertibles, which was driven by both higher stock prices and low issuance of new convertible securities, may continue. Given recent low interest rates, the convertible securities market shrunk as corporations chose to issue regular bonds rather than new convertibles. At the same time, the supply of existing convertibles contracted because of redemptions and conversions. The resulting imbalances in supply and demand relationships have been to the advantage of the owners of convertibles, who reap the benefits of higher prices. One other result, however, is that the normal defensive characteristics of convertibles may have been reduced. As prices have risen, the downside risks may have increased. Going forward, we expect to maintain our investment discipline and to continue to base our security selections on fundamental analysis of individual companies.

Most convertible securities are not investment grade and are therefore more speculative in nature than securities with higher ratings.

Note 6. Lending of Portfolio Securities

Effective June 27, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous securities lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

At February 29, 2012, securities valued at $37,676,682 were on loan, by cash collateral of $39,478,571 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Note 7. Custody Credits

Prior to June 27, 2011, the Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through June 27, 2011, these credits reduced total expenses by $51.

Note 8. Affiliated Money Market Fund

Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 10. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on June 27, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period June 27, 2011 through December 12, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Convertible Securities 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 Convertible Securities Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned 3.45% without sales charge. The fund lagged its benchmark, the S&P 500 Index, which returned 5.12%. In an environment of low interest rates, we believe that income-hungry investors focused on the dividend-paying potential of stocks rather than on business fundamentals or growth prospects. Because our strategy generally seeks a more balanced total return approach, we were underexposed to the one-dimensional highest dividend-paying segment of the market, which outperformed during the 12-month period. Stock selection in the consumer discretionary, information technology and industrials sectors helped returns during the period, while certain energy holdings hurt.

The U.S. economy picks up momentum

During the first half of the 12-month period, a series of natural disasters in Japan, Europe's debt problems and wrangling in Washington over the federal budget and the national debt dominated world headlines. U.S. economic news was lackluster and job growth was disappointing. However, the pace of growth picked up in the second half of the period and, as fears of a lapse back into recession faded, prospects brightened. Consumer confidence improved even though consumers remain under pressure, with no real increase in disposable income and a continued decline in household net worth. The labor markets added more than a million new jobs from September 2011 through February 2012, and the jobless rate fell to 8.3%. Headline inflation—which tracks a broad range of consumer expenditures, including food and energy—remained below its long-term average. Even manufacturing held its ground. A modest slowdown in manufacturing activity late in the summer of 2011 raised concern that this lynchpin of the recovery was ready to turn downward. However, manufacturing activity stabilized and the manufacturing expansion continued into 2012. Housing continues to be the one nagging weak spot in the economy. Yet, home sales edged modestly higher over the year, and there is hope that a bottom in the housing market is in sight.

Stock selection generated mixed results

Energy stocks generally detracted from returns relative to the index. Oil service companies Schlumberger and Halliburton underperformed, as investors expressed concerns that falling natural gas prices in the United States would lead to reduced profitability due to potential rig closings. In light of these developments, we sold both stocks. Rising tensions in the Middle East, particularly in Egypt and Libya, hurt oil and gas producers Apache and Occidental Petroleum (2.0% of net assets). The increased risk of civil war in both countries drove fears of potential production disruptions. We sold Apache but retained the fund's position in Occidental, as we are more comfortable with its diversification outside of the Middle East, including a recent California shale discovery.

By contrast, stock picking in the consumer discretionary sector made a positive contribution to fund returns. Top contributors were retailers Macy's and Limited Brands, owner of Victoria's Secret (1.5% and 1.1% of net assets, respectively). We targeted these names because higher net worth shoppers are more protected from relatively high unemployment levels. Both companies also sought ways to reward shareholders with cash payouts over the past 12 months.

Portfolio Managers' Report (continued) – Columbia Large Cap Core Fund

We also owned Apple and Teradata, top performers in the information technology sector (5.2% and 0.7% of net assets, respectively). Apple's stock rose on the strength of iPad 2, iPhone 4 and an iPhone contract with Verizon Wireless. The company also benefited from lower prices on components, including memory chips, which increased profit margins. Analytic data solutions provider Teradata was a beneficiary of the move towards centralized data centers as companies migrated away from their old practice of storing data on multiple servers.

In the industrials sector, Goodrich and Union Pacific were top contributors. Goodrich, a supplier of systems and services to the aerospace and defense industries, was one of the fund's long-term holdings. It was acquired by United Technologies at an attractive price and is no longer in the portfolio. Western railroad company Union Pacific benefited from improving trends in basic industries, such as chemicals and automobiles. The company is also one of only two railroad companies operating in the Western United States, and its strong presence in Western ports helped increase its exposure to Asian boat-to-train trade. We sold the position when it reached our target price.

Looking forward

As the macroeconomic environment in the United States continues to stabilize, we believe it will create an ideal environment for managers who focus on stock selection. Companies that do a majority of their business in the United States look particularly appealing now, as Europe continues to work through its debt restructuring and Asian economic growth decelerates. Against this backdrop, we have positioned the fund in companies that we believe have good balance sheets and strong industry positions that are experiencing positive change that we believe can drive future success. To find these investments, we continue to draw on three independent and uncorrelated research sources—fundamental research, systematic models and portfolio management team input—while also continuing to focus on after-tax returns on behalf of shareholders.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Columbia Large Cap Core Fund, February 29, 2012

service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Foreign Currency Transactions and Translation

Derivative Instruments

Columbia Large Cap Core Fund, February 29, 2012

fair value of other derivatives or with any collateral amounts posted by the Fund or any counterparty.

Options

Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. The Fund purchased and wrote option contracts to generate yield by writing options with strike prices commensurate with values at which we are comfortable selling the underlying stock. Completion of transactions for option contracts traded in the OTC market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain OTC option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the counterparty or the Fund upon closure, exercise or expiration of the contract.

Contracts and premiums associated with options contracts written for the year ended February 29, 2012 are as follows:

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to a percentage of the Fund's average daily net assets that declines from 0.06% to 0.03% as the Fund's net assets increase. The effective administration fee rate for the year ended February 29, 2012 was 0.06% of the Fund's average daily net assets.

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

Class A	0.19	%
Class B	0.20

The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund's net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, do not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.16	%

Class C	1.91
Class I	0.81
Class W	1.16
Class Z	0.91

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for deferral/reversal of wash sale losses, Trustees' deferred compensation and post-October capital losses. To the extent these differences are permanent, reclassifications are made among the components of the Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Undistributed net investment income	$	53,946
Accumulated net realized loss		—
Paid-in capital		(53,946	)

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

The tax character of distributions paid during the years indicated was as follows:

Year ended				February 29, 2012				February 28, 2011
Ordinary income				$	11,226,331			$	7,685,219

Columbia Large Cap Core Fund, February 29, 2012

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	1,475,605
Undistributed long-term capital gains		—
Unrealized appreciation		187,945,595

At February 29, 2012, the cost of investments for federal income tax purposes was $990,868,919 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	193,183,054
Unrealized depreciation	$	(5,237,459	)
Net unrealized appreciation	$	187,945,595

Year of expiration				Amount
2018				$	52,694,574

For the year ended February 29, 2012, $65,252,956 of capital loss carryforward was utilized.

Columbia Large Cap Core Fund acquired unrealized capital gains in connection with the merger with Columbia Blended Equity Fund (Note 12). Due to the acquisition of unrealized capital gains the yearly utilization of the Fund's capital loss carryforward may be limited by the Internal Revenue Code.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $2,352,901,142 and $2,615,382,108, respectively, for the year ended February 29, 2012.

Note 6. Regulatory Settlements

During the year ended February 29, 2012, the Fund received payments of $64,591 resulting from certain regulatory settlements with third parties in which the Fund had participated. The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Columbia Large Cap Core Fund, February 29, 2012

Note 7. Lending of Portfolio Securities

Effective June 27, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $98,046,888 were on loan, secured by cash collateral of $100,975,477 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Note 8. Custody Credits

Note 9. Affiliated Money Market Fund

Note 10. Shareholder Concentration

At February 29, 2012, one unaffiliated shareholder account owned 44.2% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Affiliated shareholder accounts owned 38.6% of the outstanding shares of the Fund. Subscription and redemption activity by

Columbia Large Cap Core Fund, February 29, 2012

concentrated accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on June 27, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period June 27, 2011 through December 12, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

Note 12. Fund Merger

At the close of business on March 11, 2011, the Fund acquired the assets and assumed the identified liabilities of Columbia Blended Equity Fund. The reorganization was completed after shareholders of Columbia Blended Equity Fund approved the plan on February 15, 2011. The purpose of the transaction was to combine two funds managed by the Investment Manager with comparable investment objectives and strategies.

The aggregate net assets of the Fund immediately before the acquisition were $1,218,171,435 and the combined net assets immediately after the acquisition were $1,319,804,105.

The merger was accomplished by a tax-free exchange of 6,625,629 shares of Columbia Blended Equity Fund valued at $101,632,670 (including $34,347,901 of unrealized appreciation).

In exchange for Columbia Blended Equity Fund shares, the Fund issued the following number of shares:

	Shares
Class A		34,275
Class C		14,642
Class Z		7,530,591

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, Columbia Blended Equity Fund's cost of investments was carried forward.

The financial statements reflect the operations of the Fund for the period prior to the merger and the combined fund for the period subsequent to the merger. Because the combined investment portfolios have been managed as a single integrated portfolio since the merger was completed, it is not practicable to separate the amounts of revenue and earnings of Columbia Blended Equity Fund that have been included in the combined Fund's Statement of Operations since the merger was completed.

Columbia Large Cap Core Fund, February 29, 2012

Assuming the merger had been completed on March 1, 2011, the Fund's pro-forma net investment income, net gain on investments, net change in unrealized depreciation and net increase in net assets from operations for the year ended February 29, 2012 would have been approximately $11.9, $66.6, $(56.5) and $22.0 million, respectively.

Note 15. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and rule in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Large Cap Core 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 Large Cap Core Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent, provide a reasonable basis for our opinion.

* All ratings are based on Class Z shares as of 12/31/2011. Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund's independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –2.08% without sales charge. The fund held up better than its benchmark, the Russell 2000 Value Index, which return –2.72% for the same period. Security selection, which targeted small-cap companies with attractively valued stocks and improving earnings prospects, helped shore up performance in a difficult environment for small-cap stocks and more than offset the negative impact of certain sector allocations.

Market volatility rocked small-cap stocks

After a year of extreme volatility, small-cap stocks ended the 12-month reporting period modestly behind where they had started. The market was unsettled early in the period by unrest in the Middle East, a nuclear meltdown and tsunami disaster in Japan and a sovereign debt crisis in Europe. Concerns accelerated over the summer amid slowing global economic growth, Congress's inability to address the federal budget deficit and Standard & Poor's subsequent decision to downgrade U.S. debt. Against this backdrop, equity markets worldwide fell sharply in the third quarter, with small-cap stocks posting especially steep losses. Signs that the U.S. economy was improving and that Europe was taking steps to address its problems spurred a fourth-quarter market turnaround that extended into early 2012. Within the Russell 2000 Value Index, defensive utilities stocks posted the strongest returns, while energy stocks were down sharply.

Strong stock selection in consumer discretionary and consumer staples

The fund picked up the most ground versus the Russell index from stock picks in the consumer discretionary sector, where winners included Domino's Pizza and specialty retailer GNC Holdings (1.0% and 0.9% of net assets, respectively). Domino's stock moved sharply higher, driven by better-than-expected domestic and international same-store sales, robust overseas expansion and higher store traffic after a well-advertised upgrade of its pizza recipe. Shares of nutritional products company GNC also posted steep gains, buoyed by increased sales and improved merchandising. Security selection in the consumer staples sector contributed, with notable gains from investments in the personal products industry. The stock of personal care products company Nu Skin Enterprises (1.0% of net assets) advanced as increased global sales of new products boosted earnings.

Added gains from industrials and health care

Security selection in industrials further aided performance. Top contributors included United Rentals (1.0% of net assets), which rents out construction equipment and tools. Its shares benefited as economic uncertainty led more companies and contractors to rent equipment instead of buying it. Stock picks in the health care sector also aided performance. Standouts included managed health-care companies Wellcare Health Plans (1.1% of net assets) and HealthSpring, whose stocks benefited from growth in insured lives as more states looked for ways to control health-care costs. HealthSpring also benefited from being acquired by a larger competitor during the period.

Portfolio Managers' Report (continued) – Columbia Small Cap Value Fund II

Modest disappointments from materials, utilities and tech

The fund lost some ground from security selection within materials, where detractors included plastics manufacturer Georgia Gulf (position eliminated), whose business was pressured by continued weakness in the housing market. An underweight in utilities, where we did not find many stocks that met our valuation criteria, and an overweight in technology, one of the weaker performing sectors in the Russell 2000 Value Index, also hampered results. Elsewhere, detractors included hospital operators Kindred Healthcare and Vanguard Health Systems (0.5% of and 0.4% of net assets, respectively). Kindred suffered from cuts in Medicare reimbursement, while Vanguard was hurt by weaker-than-predicted hospital admissions. The stock of medical equipment company Invacare declined when the government's Food and Drug Administration criticized the company's manufacturing operations. We sold the position. In technology, specialty semiconductor chip manufacturer Silicon Image (0.5% of net assets) detracted, as investors shied away from higher volatility stocks.

Looking ahead

Going forward, the fund will continue to focus on undervalued stocks with strong underlying earnings prospects and improving operating performance. We remain especially interested in "out-of-the-limelight" companies that seem to have been overlooked by Wall Street research, companies that may be out of favor with investors and companies whose operating fundamentals are on a positive trajectory. The fund ended the period with overweights versus its Russell benchmark in technology and industrials and underweights in financials and utilities.

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

Stocks of small-cap companies pose special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Notes to Financial Statements – Columbia Small Cap Value Fund II
February 29, 2012

Note 1. Organization

Columbia Small Cap Value Fund II (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are only available to qualifying institutional investors.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange

Columbia Small Cap Value Fund II, February 29, 2012

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Foreign Currency Transactions and Translation

Repurchase Agreements

Security Transactions

Income Recognition

Corporate actions and dividend income are recorded on the ex-dividend date.

Interest income is recorded on the accrual basis.

Expenses

General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of

Effective July 25, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

Note 12. Information Regarding Pending and Settled Legal Proceedings

In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds (currently branded as Columbia) and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considers and rules in a case captioned Jones v. Harris Associates, which involves issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

Ameriprise Financial and its affiliates have cooperated with the SEC and the MDOC in these legal proceedings, and have made regular reports to the funds' Boards of Trustees.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Small Cap Value Fund II

In our opinion, the accompanying statement of assets and liabilities, including the investment portfolio, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Columbia Small Cap Value Fund II (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

* All ratings are based on Class Z shares as of 12/31/2011. Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund's independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

Columbia Funds are distributed by Columbia Management Investment Distributors, Inc., member FINRA, and managed by Columbia Management Investment Advisers, LLC.

The "with sales charge" returns include the maximum initial sales charge of 5.75% for Class A shares and the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares and 1.00% for Class C shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would have been lower.

Class I and Class R were initially offered by the fund on September 27, 2010.

All results shown assume reinvestment of distributions. Class I and Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class R shares are sold at net asset value with a distribution (Rule 12b-1) fee. Class I, Class R and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund's prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

For the 12-month period that ended February 29, 2012, the fund's Class A shares returned –9.51% without sales charge. The fund's benchmark, the MSCI EAFE Value Index (Net), returned –9.85% over the same period. In a difficult period for international stock markets, security selection and group weights in the pharmaceuticals industry and companies domiciled in Japan aided fund performance relative to the index. Please keep in mind that industry and country weights are a residual of our bottom-up, stock-specific investment approach.

Portfolio activity

Advances among the fund's holdings in the pharmaceuticals and tobacco industries had the most substantial impact on returns during the 12-month period. Top-performing positions in these industries included GlaxoSmithKline, a U.K. pharmaceutical company and Japan-based Japan Tobacco (1.7% and 1.1% of net assets, respectively).

Stock selection within the household durables and insurance industries proved unfavorable to performance relative to the index. In addition, the fund had more exposure than the index to securities in Italy, which contributed to weaker results. By contrast, the fund's holdings in the wireless telecommunications services and multiline retail industries performed better than the index, helping both absolute and relative performance.

From a country perspective, gains from companies based in the United Kingdom, New Zealand and Ireland made positive contributions to returns. Kingfisher, a U.K. specialty retail company (1.3% of net assets), Telecom Corp. of New Zealand (position eliminated) and CRH PLC, a construction materials company from Ireland (1.5% of net assets) were among the standout performers from these countries.

Research drives portfolio changes

As a result of our company-by-company analysis, we made adjustments to certain existing positions within the fund during the year. We sold the fund's position in Nokia, a Finland-based communication equipment company, to pursue what we believe to be more attractive opportunities. During the same period, we purchased shares of Akzo Nobel (0.8% of net assets), the Netherlands-based chemical company and America Movil SAB (0.9% of net assets), a wireless telecommunications services company based in Mexico, at prices that we considered to be attractive.

Looking ahead

The last 12 months were challenging for the fund. In this environment, the large-cap investment committee continued to actively monitor and assess the broad global economic developments, especially those coming out of Europe. When and where possible, the committee incorporates changes into company-level valuations, such as in the form of lower normalized earnings multiples, longer time value of money discounts, or lower returns on equity. Amid the macroeconomic and geopolitical

Portfolio Managers' Report (continued) – Columbia International Value Fund

challenges facing the global economy, we continue to identify and invest in potentially under-valued companies trading at a discount to their estimated intrinsic values, or what we believe they are worth.

Equity securities are affected by stock market fluctuations that occur in response to economic and business developments.

International investing may involve special risks, including foreign taxation, currency risks, risks associated with possible differences in financial standards and other risks associated with future political and economic developments.

Investing in emerging markets may involve greater risks than investing in more developed countries. In addition, concentration of investments in a single region may result in greater volatility.

Notes to Financial Statements – Columbia International Value Fund
February 29, 2012

Note 1. Organization

Columbia International Value Fund (the Feeder Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

The value of the Feeder Fund's investment in Columbia International Value Master Portfolio (the Master Portfolio) included in the Statement of Assets and Liabilities reflects the Feeder Fund's proportionate amount of beneficial interests in the net assets of the Master Portfolio, which is equal to 92.0% at February 29, 2012. The financial statements of the Master Portfolio, including its investment portfolio, are included elsewhere within this report and should be read in conjunction with the Feeder Fund's financial statements. Another fund that is managed by the Investment Manager, not registered under the 1940 Act, and whose financial statements are not presented here, also invests in the Master Portfolio.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Feeder Fund offers Class A, Class B, Class C, Class I, Class R and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class B shares may be subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will generally convert to Class A shares eight years after purchase. The Feeder Fund no longer accepts investments by new or existing investors in the Feeder Fund's Class B shares, except in connection with the reinvestment of any dividend and/or capital gain distributions in Class B shares of the Feeder Fund and exchanges by existing Class B shareholders of certain other funds within the Columbia Family of Funds.

Class C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are only available to qualifying institutional investors.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Feeder Fund's prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Feeder Fund in the preparation of its financial statements.

Security Valuation

The Feeder Fund invests all or substantially all of its assets in the Master Portfolio. See the Notes to Financial Statements for the Master Portfolio included elsewhere in this report for the Master Portfolio's valuation policies.

Foreign Currency Transactions and Translation

Columbia International Value Fund, February 29, 2012

currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.

For financial statement purposes, the Feeder 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.

Security Transactions

Expenses

General expenses of the Trust are allocated to the Feeder Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Feeder Fund are charged to the Feeder Fund. Expenses directly attributable to a specific class of shares are charged to that share class.

Determination of Class Net Asset Value

All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Feeder 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.

The Feeder Fund records its proportionate share of investment income, realized and unrealized gains (losses) and expenses reported by the Master Portfolio on a daily basis. The investment income, realized and unrealized gains (losses) and expenses are allocated daily to investors of the Master Portfolio based upon the relative value of their investment in the Master Portfolio.

Federal Income Tax Status

The Feeder 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 Feeder 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 Feeder Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign Taxes

The Feeder Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Feeder Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Feeder Fund level, based on statutory rates. The Feeder Fund accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction.

Distributions to Shareholders

Guarantees and Indemnifications

Under the Trust's organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its Feeder Fund. In addition, certain of the Feeder Fund's contracts with its service providers contain general indemnification clauses. The Feeder Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Feeder Fund cannot be determined, and the Feeder Fund has no historical basis for predicting the likelihood of any such claims.

Columbia International Value Fund, February 29, 2012

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. The Feeder Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.17% of the Feeder Fund's average daily net assets, less the fees that were payable by the Feeder Fund as described under the Pricing and Bookkeeping Fees note below.

Pricing and Bookkeeping Fees

Prior to August 8, 2011, the Feeder Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Feeder Fund. The Feeder Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Feeder Fund. Under the State Street Agreements, the Feeder Fund paid 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 Feeder Fund for the month. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Feeder Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective August 8, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Effective June 1, 2011, other expenses are for, among other things, certain expenses of the Feeder Fund or the Board including: Fund boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. Payment of these Feeder Fund and Board expenses is facilitated by a company providing limited administrative services to the Feeder Fund and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $2,883.

Compensation of Board Members

Board members are compensated for their services to the Feeder Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not "interested persons" of the Feeder Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Feeder Fund's liability for these amounts is adjusted for market value changes and remains in the Feeder Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Feeder Fund in accordance with federal securities regulations. Effective April 1, 2011, the Feeder Fund's expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Feeder Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Feeder Fund. The Transfer Agent has contracted with Boston Financial Data Services (BFDS) to serve as sub-transfer agent.

Columbia International Value Fund, February 29, 2012

The Transfer Agent receives monthly account-based service fees based on the number of open accounts and is reimbursed by the Feeder Fund for the fees and expenses the Transfer Agent pays to financial intermediaries that maintain omnibus accounts with the Feeder Fund that is a percentage of the average aggregate value of the Feeder Fund's shares maintained in each such omnibus account (other than omnibus accounts for which American Enterprise Investment Services Inc. is the broker of record or accounts where the beneficial shareholder is a customer of Ameriprise Financial Services, Inc., which are paid a per account fee). The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Feeder Fund (with the exception of out-of-pocket fees).

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Feeder Fund's effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A	0.19	%
Class B	0.18
Class C	0.19
Class R	0.26
Class Z	0.19

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the Feeder Fund's initial minimum investment requirements to reduce the impact of small accounts on transfer agent fees. These minimum account balance fees are recorded as part of expense reductions in the Statement of Operations. For the year ended February 29, 2012, these minimum account balance fees reduced total expenses by $1,440.

Distribution and Service Fees

The Feeder Fund has an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. Pursuant to Rule 12b-1 under the 1940 Act, the Board has approved, and the Feeder Fund has adopted, distribution and shareholder service plans (the Plans) which set the distribution and service fees for the Feeder Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Feeder Fund and providing services to investors.

The Plans require the payment of a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Feeder Fund. The Plans also require the payment of a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75%, 0.50% and 0.50% of the average daily net assets attributable to Class A, Class B, Class C and Class R shares, respectively.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Feeder Fund shares were $81,986 for Class A, $1,025 for Class B and $4,325 for Class C shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective July 1, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Feeder Fund's net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Feeder Fund's custodian, do not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.37	%
Class B	2.12
Class C	2.12
Class I	0.97
Class R	1.62
Class Z	1.12

Columbia International Value Fund, February 29, 2012

Prior to July 1, 2011, the Investment Manager and its affiliates contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), so that the Feeder Fund's net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Feeder Fund's custodian, did not exceed the following annual rates as a percentage of the class' average daily net assets:

Class A	1.60	%
Class B	2.35
Class C	2.35
Class I	1.25
Class R	1.85
Class Z	1.35

Under the agreement, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Feeder Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, extraordinary expenses and any other expenses the exclusion of which is specifically approved by the Board. This agreement may be modified or amended only with approval from all parties.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for deferral/reversal of wash sales, capital loss carryforwards, passive foreign investment company (PFIC) holdings, deferred trustees expense, post-October loss deferrals and reversals, proceeds from litigation settlements, foreign currency transactions and allocations from the Master Portfolio. To the extent these differences are permanent, reclassifications are made among the components of the Feeder Fund's net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:

Excess of distributions over net investment income	$9,844,354
Accumulated net realized loss	(9,035,125	)
Paid-in capital	(809,229	)

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

The tax character of distributions paid during the years indicated was as follows:

				Year ended February 29, 2012				Year ended February 28, 2011
Ordinary income				$	46,281,246			$	48,570,845

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	2,049,426
Undistributed accumulated long-term gain		—
Unrealized depreciation		N/A*

* See the Master Portfolio notes to financial statements for tax basis information.

Columbia International Value Fund, February 29, 2012

At February 29, 2012, the aggregate gross unrealized appreciation and depreciation based on cost of investments for federal income tax purposes were:

Unrealized appreciation					N/A*
Unrealized depreciation					N/A*
Net unrealized depreciation					N/A*

* See the Master Portfolio notes to financial statements for tax basis information.

Year of expiration	Amount
2018	$	185,725,377
2019		68,376,538
Unlimited long-term		80,594,079
Total	$	334,695,994

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Act) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. Under the Act, the Feeder Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused.

Under current tax rules, regulated investment companies can elect to treat certain late-year ordinary losses incurred and post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. As of February 29, 2012, the Feeder Fund will elect to treat post-October capital losses of $51,269,575 as arising on March 1, 2012.

Management of the Feeder Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. However, management's conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Feeder Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Regulatory Settlements

During the year ended February 29, 2012, the Feeder Fund received $81,090 as a result of a settlement of an administrative proceeding brought by the Securities and Exchange Commission against an unaffiliated third party relating to market timing and/or late trading of mutual funds. This amount represented the Feeder Fund's portion of the proceeds from the settlement (the Feeder Fund was not a party to the proceeding).

During the year ended February 28, 2011, the Feeder Fund received payments of $108,538 resulting from certain regulatory settlements with third parties in which the Feeder Fund had participated.

The payments have been included in "Proceeds from regulatory settlements" in the Statement of Changes in Net Assets.

Note 6. Custody Credits

Prior to August 8, 2011, the Feeder Fund had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Feeder Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Feeder Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through August 7, 2011, there were no custody credits.

Note 7. Shareholder Concentration

At February 29, 2012, three unaffiliated shareholder accounts owned 62.3% of the outstanding shares of the Feeder Fund.

Columbia International Value Fund, February 29, 2012

The Feeder Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Feeder Fund.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia International Value 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 International Value Fund (the "Fund") (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

Notes to Financial Statements – Columbia International Value Master Portfolio

February 29, 2012

Note 1. Organization

Columbia Funds Master Investment Trust, LLC (the Master Trust), is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Delaware limited liability company. Information presented in these financial statements pertains to Columbia International Value Master Portfolio (the Master Portfolio), a series of the Master Trust.

The following investors were invested in the Master Portfolio at February 29, 2012:

Columbia International Value Fund (the Feeder Fund)					92.0	%
Columbia Management Private Funds VII, LLC—International Value Fund					8.0	%

The Master Portfolio serves as a master portfolio for the Columbia International Value Fund which operates as a feeder fund in a master/feeder structure.

Each investor in the Master Portfolio is treated as an owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains (losses) of the Master Portfolio.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Master Portfolio in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Columbia International Value Master Portfolio, February 29, 2012

value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine value.

Foreign Currency Transactions and Translation

For financial statement purposes, the Master Portfolio 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.

Repurchase Agreements

The Master Portfolio may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Master Portfolio, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a Master Portfolio's ability to dispose of the underlying securities and a possible decline in the value of the underlying securities during the period while the Master Portfolio seeks to assert its rights.

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

Awards from class action litigation are recorded as a reduction of cost if the Master Portfolio still owns the applicable securities on the payment date. If the Master Portfolio no longer owns the applicable securities, the proceeds are recorded as realized gains.

Federal Income Tax Status

The Master Portfolio is treated as a partnership for federal income tax purposes and therefore is not subject to federal income tax. Each investor in the Master Portfolio will be subject to taxation on its allocated share of the Master Portfolio's ordinary income and capital gains.

The Master Portfolio's assets, income and distributions will be managed in such a way that the Feeder Fund will be able to continue to qualify as a registered investment company by investing its assets through its Master Portfolio.

Foreign Taxes

The Master Portfolio may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Master Portfolio will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Master Portfolio level, based on statutory rates. The Master Portfolio accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable.

Guarantees and Indemnifications

Under the Master Trust's organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Master Trust or its Master Portfolio. In addition, certain of the Master Portfolio's contracts with its service providers contain general indemnification clauses. The Master Portfolio's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Master Portfolio cannot be determined, and the Master Portfolio has no historical basis for predicting the likelihood of any such claims.

Recent Accounting Pronouncement

Fair Value Measurements and Disclosures

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), determines which securities will be purchased, held or sold. The management fee is an annual fee that is equal to a percentage of the Master Portfolio's average daily net assets that declines from 0.85% to 0.66% as the Master Portfolio's net assets increase. The effective management fee rate for the year ended February 29, 2012 was 0.80% of the Master Portfolio's average daily net assets.

Subadvisory Agreement

The Investment Manager has entered into a Subadvisory Agreement with Brandes Investment Partners, L.P. (Brandes), the subadviser of the Master Portfolio. The Investment Manager compensates Brandes to manage the investments of the Master Portfolio's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Master Portfolio Administrator. The Master Portfolio pays the Master Portfolio Administrator an annual fee for administration and accounting services equal to 0.05% of the Master Portfolio's average daily net assets, less the fees that were payable by the Master Portfolio as described under the Pricing and Bookkeeping Fees note below.

Pricing and Bookkeeping Fees

Prior to August 8, 2011, the Master Portfolio had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Master Portfolio. The Master Portfolio also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Master Portfolio. Under the State Street Agreements, the Master Portfolio paid 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 Master Portfolio for the month. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Master Portfolio also reimbursed State Street for certain out-of-pocket expenses and charges. Effective August 8, 2011, these services are provided under the Administrative Services Agreement discussed above.

Compensation of Board Members

Board members are compensated for their services to the Master Portfolio as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not "interested persons" of the Master Portfolio, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Master Portfolio's liability for these amounts is adjusted for market value changes and remains in the Master Portfolio until distributed in accordance with the Plan.

Columbia International Value Master Portfolio, February 29, 2012

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Master Portfolio in accordance with federal securities regulations. The Master Portfolio does not bear any of the expenses associated with the Chief Compliance Officer.

Other Fees

Effective June 1, 2011, other expenses are for, among other things, certain expenses of the Master Portfolio or the Board, including: Master Portfolio boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. Payment of these Master Portfolio and Board expenses is facilitated by a company providing limited administrative services to the Master Portfolio and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $1,899.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

The Investment Manager and certain of its affilates have voluntarily agreed to waive fees and/or reimburse certain expenses (excluding certain fees and expenses, such as brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Master Portfolio's ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Master Portfolio's custodian, do not exceed the annual rate of 0.90% of the Master Portfolio's average daily net assets. This arrangement may be modified or terminated by the Investment Manager at any time.

Note 4. Federal Tax Information

At February 29, 2012, the cost of investments for federal income tax purposes was $1,648,707,921 and the aggregate gross unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation	$	112,817,440
Unrealized depreciation	$	(339,778,321	)
Net unrealized depreciation	$	(226,960,881	)

Management of the Master Portfolio has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. However, management's conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Master Portfolio's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $229,905,363 and $713,617,654, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

Effective August 8, 2011, the Master Portfolio has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Master Portfolio. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Master Portfolio into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $128,222,861 were on loan, secured by cash collateral of $135,181,153 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Master Portfolio from losses resulting from a borrower's failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Master Portfolio in connection with the securities lending program. Loans are subject to

Columbia International Value Master Portfolio, February 29, 2012

termination by the Master Portfolio or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Pursuant to the Agreement, the Master Portfolio receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses. Net income earned from securities lending for the year ended February 29, 2012 is disclosed in the Statement of Operations. The Master Portfolio continues to earn and accrue interest and dividends on the securities loaned.

Prior to August 8, 2011, the Master Portfolio participated in a securities lending arrangement with State Street. Each security on loan was collateralized in an amount at least equal to the market value of the securities loaned plus accrued income from the investment of collateral. The income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, was paid to the Master Portfolio.

Note 7. Custody Credits

Prior to August 8, 2011, the Master Portfolio had an agreement with its custodian bank under which custody fees may have been reduced by balance credits. These credits are recorded as part of expense reductions on the Statement of Operations. The Master Portfolio could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Master Portfolio may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through August 7, 2011, there were no custody credits.

Note 8. Affiliated Money Market Fund

Effective August 8, 2011, the Master Portfolio may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Master Portfolio and other affiliated funds. The income earned by the Master Portfolio from such investments is included as "Dividends from affiliates" in the Statement of Operations. As an investing fund, the Master Portfolio indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 9. Line of Credit

The Master Portfolio has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Master Portfolio may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on August 8, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Master Portfolio and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Master Portfolio also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum.

For the period August 8, 2011 through December 12, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Master Portfolio also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

For the period June 27, 2011 through August 7, 2011, the Master Portfolio and certain other funds managed by the Investment Manager participated in a $100 million committed, unsecured revolving credit facility provided by State Street. For the period May 16, 2011 through June 26, 2011, the collective borrowing amount of the credit facility was $150 million committed, unsecured revolving credit facility provided by State Street. For the period March 28, 2011 through May 15, 2011, the collective borrowing amount of the credit facility was $225 million. Prior to March 28, 2011, the collective borrowing amount of the credit facility was $280 million. Iinterest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum. The Master Portfolio also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.125% per annum.

For the year ended February 29, 2012, the average daily loan balance outstanding on days when borrowing existed was $12,502,817 at a weighted average interest rate of 1.41%.

Report of Independent Registered Public Accounting Firm

To the Holders and Trustees of Columbia Funds Master Investment Trust, LLC

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 International Value Master Portfolio (constituting a series of Columbia Funds Master Investment Trust, LLC, hereafter referred to as the "Master Portfolio") at February 29, 2012, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 Master Portfolio'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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

President’s Message

LOGO

Dear Shareholders,

Americans were dispirited in the fourth quarter of 2011 by Washington’s inability to reach a plan for deficit reduction and Europe’s piecemeal attempt to address its own fiscal issues. Yet, there was sufficient good news to encourage risk taking, buoying both stocks and bonds to solid gains.

U.S. economic data surprised on the upside and fears of recession abated. With the bar of expectations set low, investors responded positively to the announcement that the economy had expanded by 1.8% in the third quarter. Consumer confidence improved, even though consumers remain under pressure with no real increase in disposable income and a continued decline in household net worth. Headline inflation — which tracks a broad range of consumer expenditures, including food and energy — declined. Even manufacturing held its ground.

Against this backdrop, the U.S. equity markets logged solid

returns. The S&P 500 Index gained 11.82%, moving into positive territory for the year with quarterly advances in all ten sectors. Mid- and small-cap stocks did even better. Value outperformed growth across all market capitalizations. Energy stocks led the market, as the price of oil moved above $100 a barrel in December. Industrials and materials stocks rose, buoyed by improving economic data. The U.S. fixed-income markets logged modest but solid returns. High-yield bonds were the best performers as the economy showed signs of improvement. Emerging market bonds were strong performers, as inflation came under control in key regions. Municipal bonds and Treasuries eked out only modest gains, as investors moved away from quality in favor of riskier assets.

* All ratings are based on Class Z shares as of 12/31/2011. Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund’s independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges/loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.)

The Morningstar Rating^TM is for Class Z shares only; other classes may have different performance characteristics and may have different ratings. ^©2012 Morningstar, Inc. All Rights Reserved.

The “with sales charge” returns include the applicable contingent deferred sales charge of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter for Class B shares. The “without sales charge” returns do not include the effect of sales charges. If they had, returns would be lower.

All results shown assume reinvestment of distributions. Class A shares are sold at net asset value. Class I and Class Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class I and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund’s prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

The returns shown for periods prior to the share class inception date (including returns since inception, which are since fund inception) include the returns of the fund’s Class Z shares, the fund’s oldest share class. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

Understanding Your Expenses – Columbia Large Cap Index Fund

Analyzing your fund’s expenses

To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. 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 the period.

For the 12-month period that ended February 29, 2012, the fund’s Class A shares returned 4.67% without sales charge. The S&P 500 Index returned 5.12%. The fund seeks to approximate the benchmark weights of securities represented in the S&P 500 Index. As such, its return was slightly below the return of the index, after fees and expenses, which the index does not incur. Despite a rocky period midway through 2011, stock prices climbed for the third consecutive year, buoyed by sectors that are sensitive to economic growth.

U.S. economy picks up momentum

During the first half of the 12-month period, a series of natural disasters in Japan, Europe’s debt problems and wrangling in Washington over the federal budget and the national debt dominated world headlines. U.S. economic news was lackluster and job growth was disappointing. However, the pace of growth picked up in the second half of the period and, as fears of a lapse back into recession faded, prospects brightened. Consumer confidence improved even though consumers remain under pressure, with no real increase in disposable income and a continued decline in household net worth. The labor markets added more than a million new jobs from September 2011 through February 2012, and the jobless rate fell to 8.3%. Headline inflation — which tracks a broad range of consumer expenditures, including food and energy — remained within its historical range. Even manufacturing held its ground. A modest slowdown in manufacturing activity late in the summer of 2011 raised concern that this lynchpin of the recovery was ready to turn downward. However, manufacturing activity stabilized, and the manufacturing expansion continued into 2012. Housing continues to be the one nagging weak spot in the economy. Yet, home sales edged modestly higher over the year, and there is hope that a bottom in the housing market is in sight.

Defensive sectors drove performance

For the 12-month period, consumer staples, health care and utilities — all traditionally defensive market sectors — drove performance within the fund and the index. Trading companies & distributors, health care technology, tobacco, biotechnology and textiles, apparel & luxury goods were the top-performing industries. Technology stocks dominated the top performers. Apple, International Business Machines, Microsoft and Intel (4.0%, 1.8%, 1.9% and 1.1% of net assets, respectively) were among the top five performers. Philip Morris International (1.2% of net assets) was also a top performer for the period.

By contrast, financials, materials and energy sectors underperformed for the period. Wireless telecommunication services, real estate management & development, electronic equipment, instruments & components, diversified financial services and airlines were the five weakest industries. The worst performing stocks in terms of contribution to benchmark total return were Bank of America, Citigroup, Hewlett-Packard, JPMorgan Chase and Goldman Sachs (0.6%, 0.6%, 0.4%, 1.2% and 0.5% of net assets, respectively).

Changes to index and portfolio holdings

During the period, there were 18 additions and deletions to the index and the fund. Compuware, Tellabs, Monster Worldwide, MEMC Electronic Materials, AK Steel, Nicor, Janus Capital, ITT, Cephalon, National Semiconductor, Marshall & Isley, Radioshack, Prologis, Massey Energy, Novell, Genzyme, Qwest Communications and McAfee were deleted from the index.

Looking ahead

As the period ended, economic data suggested that economic growth will continue at a below-trend pace and that, at least in the near term, the U.S. economy has moved away from recessionary conditions. Recession odds have been reduced with the extension of the payroll tax cut and unemployment benefit programs. However, this extension is temporary and only kicks the can down the road into 2013, when severe curtailments are set to bite. And while U.S. economic data is mildly encouraging, there is still a reasonable chance of a mild recession. Europe may already be in a recession, which is likely to worsen further into 2012 as austerity measures begin to bite deeper. The good news is that these measures will initially reduce deficits, but without economic growth it is hard to make significant and persistent progress in debt reduction. So while many of the issues that worried us in 2011 continue to worry us into 2012, we are, nonetheless, cautiously optimistic about the potential for financial returns in 2012.

Fair Value Measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

Level 1 – Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date (including NAV for open-end mutual funds). Valuation adjustments are not applied to Level 1 investments.

Level 2 – Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

The Accompanying Notes to Financial Statements are an integral part of this statement.

Columbia Large Cap Index Fund

February 29, 2012

Fair Value Measurements (continued)

Level 3 – Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

The following table is a summary of the inputs used to value the Fund’s investments as of February 29, 2012:

Notes to Financial Statements – Columbia Large Cap Index Fund

February 29, 2012

Note 1. Organization

Columbia Large Cap Index Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class I and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class A shares have no sales charge.

Class B shares may be subject to a maximum Contingent Deferred Sales Charge (CDSC) of 5.00% based upon the holding period after purchase. Class B shares will generally convert to Class A shares eight years after purchase. The Fund no longer accepts investments by new or existing investors in the Fund’s Class B shares, except in connection with the reinvestment of any dividend and/or capital gain distributions in Class B shares of the Fund and exchanges by existing Class B shareholders of certain other funds within the Columbia Family of Funds.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds. Class I shares commenced operations on November 16, 2011.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund’s prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Futures and options on futures contracts are valued based upon the settlement price established each day by the board of trade or exchange on which they are traded.

Columbia Large Cap Index Fund

February 29, 2012

Derivative Instruments

Futures Contracts

Futures contracts represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought equity index futures contracts to equitize cash in order to

maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. Upon entering into futures contracts, the Fund bears risks which may include interest rates, exchange rates or securities prices moving unexpectedly, in which case, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Effects of Derivative Transactions in the Financial Statements

The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; the impact of derivative transactions on the Fund’s operations over the period including realized gains or losses and unrealized gains or losses. The derivative schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.


Fair Values of Derivative Instruments at February 29, 2012
	Asset derivatives		Liability derivatives

Risk Exposure Category	Statement of Assets and Liabilities Location	Fair Value	Statement of Assets and Liabilities Location	Fair Value
Equity contracts	Net assets — unrealized appreciation on futures contracts	$1,808,277*	Net assets — unrealized depreciation on futures contracts	$—*

*	Includes cumulative appreciation (depreciation) of futures contracts as reported in the Futures Contracts Outstanding table following the Portfolio of Investments. Only the current day’s variation margin is reported in receivables or payables in the Statement of Assets and Liabilities.

Futures Contracts		1,882

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Fund, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

The Fund receives distributions from holdings in real estate investment trusts (REITs) which report information on the character of their distributions annually. REIT distributions are allocated to dividend income, capital gain and return of capital based on estimates made by the Fund’s management if actual information has not yet been reported. Return of capital is recorded as a reduction of the cost basis of securities held. Management’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs which could result in a proportionate increase in return of capital to shareholders.

Expenses

Determination of Class Net Asset Value

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 (including net short-term capital gains), 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.

Columbia Large Cap Index Fund

February 29, 2012

Distributions to Shareholders

Guarantees and Indemnifications

Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Fair Value Measurements and Disclosures

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Administration Fees

The Investment Manager, from the administration fee it receives from the Fund, pays all operating expenses of the Fund, with the exception of brokerage fees and commissions, interest, fees and expenses of Trustees who are not officers, directors or employees of the Investment Manager or its affiliates, distribution (Rule 12b-1) and/or shareholder servicing fees and any extraordinary non-recurring expenses that may arise, including litigation.

Pricing and Bookkeeping Fees

Prior to March 28, 2011, the Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Fund. The Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Fund. The pricing and bookkeeping fees for the Fund were paid by the Investment Manager. Effective March 28, 2011, these services are now provided under the Administrative Services Agreement discussed above.

Other Fees

Columbia Large Cap Index Fund

February 29, 2012

providing limited administrative services to the Fund and the Board. For the period June 1, 2011 through February 29, 2012, other expenses paid to this company were $10,351.

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not “interested persons” of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund’s expenses associated with the Chief Compliance Officer are paid directly by Columbia. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

Under a Transfer Agency Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with Boston Financial Data Services (BFDS) to serve as sub-transfer agent.

The transfer agent fees are payable by the Investment Manager. The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Fund. The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of -pocket expenses.

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the Fund’s initial minimum investment requirements to reduce the impact of small accounts on transfer agent fees. These minimum account balance fees are recorded as part of expense reductions in the Statement of Operations. For the year ended February 29, 2012, these minimum account balance fees reduced total expenses by $14,557.

Distribution and Service Fees

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also required the payment of a monthly service fee at the maximum annual rate of 0.25% and a monthly distribution fee at the maximum annual rate of 0.75% of the average daily net assets attributable to Class B shares of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $212 for Class B shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective April 30, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rates as a percentage of the class’ average daily net assets:



Class A	0.42	%
Class B	1.17
Class I	0.17
Class Z	0.17

Under the agreement, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction

Columbia Large Cap Index Fund

February 29, 2012

taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, extraordinary expenses and any other expenses the exclusion of which is specifically approved by the Board. This agreement may be modified or amended only with approval from all parties.

Prior to April 30, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund’s expenses (excluding certain expenses, such as distribution and services fees, brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund’s ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, did not exceed 0.14% of the Fund’s average daily net assets on an annualized basis.

Prior to May 1, 2011, the Investment Manager was entitled to recover from the Fund any fees waived and/or expenses reimbursed for a three year period following the date of such fee waiver and/or reimbursement under these arrangements if such recovery did not cause the Fund’s expenses to exceed the expense limitations in effect at the time of recovery. Effective May 1, 2011, the Investment Manager has eliminated such fee recoupment provisions.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for attributes from acquired funds, capital loss carryforwards, deferral/reversal of wash sales, recognition of unrealized appreciation (depreciation) for certain derivative investments, return of capital sales basis adjustment and Trustee’s deferred compensation. To the extent these differences are permanent, reclassifications are made among the components of the Fund’s net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the

Statement of Assets and Liabilities the following reclassifications were made:



Undistributed net investment income	$190,443
Accumulated net realized loss	993,973
Paid-in capital	(1,184,416	)

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

The tax character of distributions paid during the years indicated was as follows:


	Year ended February 29, 2012		Year ended February 28, 2011
Ordinary income		$65,087,443		$51,769,128

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:



Undistributed ordinary income	$	8,809,934
Unrealized appreciation		853,432,067

At February 29, 2012, the cost of investments for federal income tax purposes was $2,762,595,090 and the aggregate gross unrealized appreciation and depreciation based on that cost was:



Unrealized appreciation	$	1,153,179,009
Unrealized depreciation	$	(299,746,942	)

Net unrealized appreciation	$	853,432,067

The following capital loss carryforward, determined at February 29, 2012, may be available to reduce taxable income arising from future

Columbia Large Cap Index Fund

February 29, 2012

net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code:



Year of expiration	Amount
2013	$	235,890
2014		66,065
2015		84,935,905
2017		19,873,230

Total	$	105,111,090

For the year ended February 29, 2012, $58,603,881 of capital loss carryforward was utilized and $303,006 expired unused.

Columbia Large Cap Index Fund acquired capital loss carryforwards in connection with the merger with RiverSource S&P 500 Index Fund of $3,639,022 (Note 10). The yearly utilization of the acquired capital loss carryforwards may be limited by the Internal Revenue Code. Any capital loss carryforwards acquired as part of a merger that is permanently lost due to the provisions under the Internal Revenue Code is included as being expired.

Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $209,472,348 and $275,612,211, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

At February 29, 2012, securities valued at $13,168,748 were on loan, secured by U.S. government securities valued at $3,813,876 and by cash collateral of $9,830,060 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower’s failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Columbia Large Cap Index Fund

February 29, 2012

Note 7. Affiliated Money Market Fund

Effective March 28, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as “Dividends from affiliates” in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 8. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned 44.6% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity of these accounts may have a significant effect on the operations of the Fund.

Note 9. Line of Credit

agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period March 28, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 10. Fund Merger

At the close of business on August 12, 2011, the Fund acquired the assets and assumed the identified liabilities of RiverSource S&P 500 Index Fund a series of RiverSource Market Advantage Series, Inc. The reorganization was completed after shareholders of RiverSource S&P 500 Index Fund approved the plan on April 27, 2011. The purpose of the transaction was to combine two funds managed by the Investment Manager with comparable investment objectives and strategies.

The aggregate net assets of the Fund immediately before the acquisition were $3,045,750,893 and the combined net assets immediately after the acquisition were $3,165,481,480.

The merger was accomplished by a tax-free exchange of 30,883,112 shares of RiverSource S&P 500 Index Fund valued at $119,730,587 (including $7,017,237 of unrealized appreciation).

Columbia Large Cap Index Fund

February 29, 2012

In exchange for RiverSource S&P 500 Index Fund shares, the Fund issued the following number of shares:



	Shares
Class A		787,315
Class Z		4,433,356

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, RiverSource S&P 500 Index Fund’s cost of investments was carried forward.

The financial statements reflect the operations of the Fund for the period prior to the merger and the combined fund for the period subsequent to the merger. Because the combined investment portfolios have been managed as a single integrated portfolio since the merger was completed, it is not practicable to separate the amounts of revenue and earnings of RiverSource S&P 500 Index Fund that have been included in the combined Fund’s Statement of Operations since the merger was completed.

Assuming the merger had been completed on March 1, 2011, the Fund’s pro-forma net investment income, net gain on investments, net change in unrealized appreciation and net increase in net assets from operations for the year ended February 29, 2012 would have been approximately $66.0 million, $64.3 million, $32.0 million and $162.3 million, respectively.

Note 11. Subsequent Events

On March 23, 2012, a group of unaffiliated shareholders of the Fund redeemed $1,271,206,650, substantially all through an in-kind transaction. This amount represented approximately 35% of the Fund’s net assets as of that date.

Note 12. Information Regarding Pending and Settled Legal Proceedings

behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants’ motion to dismiss the complaint, the District Court dismissed one of plaintiffs’ four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants’ favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considered and ruled in a case captioned Jones v. Harris Associates, which involved issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth Circuit’s decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court’s decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court’s decision in Jones v. Harris Associates. On December 9, 2010, the District Court reinstated its July 9, 2007 summary judgment order in favor of the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with the Eighth Circuit. In response to the plaintiffs’ opening appellate brief filed on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011 and oral arguments took place on November 17, 2011. On March 30, 2012, the Eighth Circuit upheld the grant of summary judgment by the District Court in favor of the defendants.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Large Cap 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 Large Cap Index Fund (the “Fund”) (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent provide a reasonable basis for our opinion.

Dear Shareholders,

U.S. economic data surprised on the upside and fears of recession abated. With the bar of expectations set low, investors responded positively to the announcement that the economy had expanded by 1.8% in the third quarter. Consumer confidence improved, even though consumers remain under pressure with no real increase in disposable income and a continued decline in household net worth. Headline inflation — which tracks a broad range of consumer expenditures, including food and energy — declined. Even manufacturing held its ground.

Against this backdrop, the U.S. equity markets logged solid returns.

The S&P 500 Index gained 11.82%, moving into positive territory for the year with quarterly advances in all ten sectors. Mid- and small-cap stocks did even better. Value outperformed growth across all market capitalizations. Energy stocks led the market, as the price of oil moved above $100 a barrel in December. Industrials and materials stocks rose, buoyed by improving economic data. The U.S. fixed-income markets logged modest but solid returns. High-yield bonds were the best performers as the economy showed signs of improvement. Emerging market bonds were strong performers, as inflation came under control in key regions. Municipal bonds and Treasuries eked out only modest gains, as investors moved away from quality in favor of riskier assets.

All ratings are based on Class Z shares as of 12/31/2011. Out of 119 Class Z share Columbia funds rated by Morningstar, 7 funds received a 5-star Overall Rating and 45 funds received a 4-star Overall Rating. The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund’s independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges/loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.)

Columbia Funds are distributed by Columbia Management Investment Distributors, Inc., member FINRA, and managed by Columbia Management Investment Advisers, LLC.

Understanding Your Expenses – Columbia Large Cap Enhanced Core Fund

Analyzing your fund’s expenses

To illustrate these ongoing costs, we provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. 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 the period. See the “Compare with other funds” below for details on how to use the hypothetical data.

In addition to the ongoing expenses which the Fund bears directly, the Fund’s shareholders indirectly bear the Fund’s allocable share of the costs and expenses of each underlying fund in which the Fund invests. You can also estimate the effective expenses paid during the period, which includes the indirect fees associated with investing in the underlying funds, by using the amounts listed in the effective expenses paid during the period column.

For the 12-month period that ended February 29, 2012, the fund’s Class A shares returned 8.41% without sales charge. The fund outperformed its benchmark, the S&P 500 Index, which returned 5.12%. The fund’s quality and valuation components generally accounted for its performance advantage over its benchmark, with each component adding value during different periods of the year. The catalyst component as described below, added value more consistently throughout the year, though with less impact.

A shifting market

Over the 12-month period covered by this report, the U.S. equity market went through several distinct phases, as sentiment shifted with economic and political news. In March and April of 2011, optimism about a continued economic recovery pushed the S&P 500 Index upward. Then, the index treaded water through July, when deep concerns about political paralysis in Washington, a downgrade of U.S. debt by Standard & Poor’s and Europe’s lingering debt crisis pushed the market lower. Yet, despite the continued overhang of European debt, the market recovered strongly in the fourth quarter of 2011 and through the first two months of 2012, driven by upbeat economic results and forecasts. Although the index was up and down in double digits at different points in the year, its 5.12% return for the full period cheered investors.

The drivers of index returns also shifted over the year. As the market declined sharply from May 2011 through September, stocks with defensive qualities strongly outperformed riskier, higher beta stocks by almost 32%. (Beta is a measure of volatility relative to the index.) Large-company stocks outperformed the smallest-capitalization stocks in the index and the top dividend payers outperformed stocks that don’t pay a dividend. By contrast, as stock prices picked up from October 2011 through February 2012, the quintile of stocks with the highest beta outperformed the quintile of stocks with the lowest beta by almost 25%. Small-cap stocks outperformed large-cap stocks and the stocks of non-dividend paying stocks outperformed stocks with the highest yield.

Stock model components drove performance advantage

The components of the fund’s stock selection model, exhibited similar, but generally more muted, behavior than the index. We divide the metrics for our stock selection model into three broad categories: valuation, which is based on fundamental measures such as earnings and cash flow relative to market values; catalyst, which measures price and business momentum; and quality, which measures such things as the quality of a company’s earnings and its overall financial strength. During the period, the most pronounced shifts in performance occurred within the fund’s quality and valuation components. For the May through September down period in the market, the fund’s high quality stocks outperformed its lower quality stocks by more than 13% and were the biggest positive driver of returns relative to the S&P 500 Index. However, as stock prices rose from October through the end of the fund’s fiscal year, the fund’s quality measures failed to distinguish between winners and losers.

The story was reversed for the fund’s valuation metrics. From May to September, the top quintile of stocks ranked by the fund’s valuation measures underperformed the bottom quintile by about 5%. After September, the fund’s valuation measures were the most positive driver of returns, with the top quintile outperforming the bottom quintile by more than 11%. The fund’s catalyst factors added value more consistently throughout the period, with the top quintile outperforming the bottom quintile by about 2% from May through September and by about 3% from October through February.

Portfolio Managers’ Report (continued) – Columbia Large Cap Enhanced Core Fund

During the period, health care, and consumer discretionary stocks were the top contributors to performance. Biogen Idec (position eliminated), a global biotech company received positive news regarding trials of a new multiple sclerosis drug and announced several strategic acquisitions and joint ventures. In financials, the fund benefited by being significantly underweight in Bank of America (0.2% of net assets), which was a poor performer, and by being overweight in the strong performing Simon Property Group (1.3% of net assets), a real estate investment trust that owns and operates regional malls and premium outlets, among other real estate properties. Other top contributors included top holding Apple (5.1% of net assets). Anticipation of the next generation iPhone was more than enough to bolster the stock against news of increased competition for smartphones and tablets, as well as the loss of its iconic chief executive Steve Jobs. Industrials and financials made the weakest showing during the period. R.R. Donnelley (0.8% of net assets), a global commercial printing company, absorbed several acquisitions and struggled with expansion plans, which took a bite out of profit margins.

The fund holds S&P futures contracts to equitize cash positions and to minimize tracking error relative to the index, which would result from holding cash in the portfolio.

Looking ahead

In the current economic environment, we plan to maintain our investment discipline and continue to seek to identify stocks that we believe have the potential to outperform within each sector. We also seek to minimize sector weight differences between the fund and its investment benchmark. We continue to favor stocks with attributes considered most important in the fund’s stock selection model: companies with attractive valuations relative to their peers, companies with strong business and market momentum and companies with good quality of earnings and financial strength. Over the long run, we have found that stocks with these characteristics have tended to outperform their peers in different macroeconomic environments.

Fair Value Measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date (including NAV for open-end mutual funds). Valuation adjustments are not applied to Level 1 investments.

Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Notes to Financial Statements – Columbia Large Cap Enhanced Core Fund

February 29, 2012

Note 1. Organization

Columbia Large Cap Enhanced Core Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

they trade, except for securities traded on the NASDAQ Stock Market, 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 mean of the latest quoted bid and asked prices on such exchanges or markets.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Futures and options on futures contracts are valued based upon 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 reliable, 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 (the Board). If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the last quoted market price for the security. The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine value.

Derivative Instruments

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The

Columbia Large Cap Enhanced Core Fund

February 29, 2012

Fund, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

The Fund receives distributions from holdings in real estate investment trusts (REITs) which report information on the character of their distributions annually. REIT distributions are allocated to dividend income, capital gain and return of capital based on estimates made by the Fund’s management if actual information has not yet been reported. Return of capital is recorded as a reduction of the cost basis of securities held. Management’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs which could result in a proportionate increase in return of capital to shareholders.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement (IMSA), Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), determines which securities will be purchased, held or sold. Effective July 1, 2011, the management fee is an annual fee that is equal to a percentage of the Fund’s average daily net assets that declines from 0.69% to 0.52% as the Fund’s net assets increase. Prior to July 1, 2011, the management fee was equal to a percentage of the Fund’s average daily net assets that declined from 0.35% to 0.16% as the Fund’s net assets increased. The effective management fee rate for the year ended February 29, 2012 was 0.56% of the Fund’s average daily net assets.

Effective July 1, 2011, the Investment Manager has contractually agreed to waive a portion of the management fee so that the net management fee will be 0.49% for the fiscal period ending June 30, 2012.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager serves as the Fund Administrator. Effective July 1, 2011, the Fund pays the Fund Administrator an annual fee for administration and accounting services equal to a percentage of the Fund’s average daily net assets that declines from 0.06% to 0.03% as the Fund’s net assets increase. Prior to July 1, 2011, the administration fee was equal to the annual rate of 0.17% of the Fund’s average daily net assets, less the fees that were payable by

the Fund as described under the Pricing and Bookkeeping Fees note below. The effective administration fee rate for the year ended February 29, 2012 was 0.10% of the Fund’s average daily net assets.

Pricing and Bookkeeping Fees

Other Fees

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not “interested persons” of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Columbia Large Cap Enhanced Core Fund

The Transfer Agent receives monthly account-based service fees based on the number of open accounts and is reimbursed by the Fund for the fees and expenses the Transfer Agent pays to financial intermediaries that maintain omnibus accounts with the Fund that is a percentage of the average aggregate value of the Fund’s shares maintained in each such omnibus account (other than omnibus accounts for which American Enterprise Investment Services Inc. is the broker of record or accounts where the beneficial shareholder is a customer of Ameriprise Financial Services, Inc., which are paid a per account fee). The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund’s effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:



Class A	0.20	%
Class R	0.20

Distribution and Service Fees

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective July 1, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rates as a percentage of the class’ average daily net assets:



Class A	0.95	%
Class I	0.63
Class R	1.20
Class Y	0.70
Class Z	0.70

Columbia Large Cap Enhanced Core Fund

February 29, 2012

Prior to July 1, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund’s expenses (excluding certain expenses, such as brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund’s ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, did not exceed the following annual rates as a percentage of the class’ average daily net assets:



Class A	0.95	%
Class I	0.57
Class R	1.20
Class Y	0.70
Class Z	0.70

Prior to May 1, 2011, the Investment Manager was entitled to recover from the Fund any fees waived and/or expenses reimbursed for a three year period following the date of such fee waiver and/or reimbursement under these arrangements if such recovery did not cause the Fund’s expenses to exceed the expense limitations in effect at the time of recovery. Effective May 1, 2011, the Investment Manager has eliminated such fee recoupment provisions.

Note 4. Federal Tax Information

For the Year Ended February 29, 2012, these differences are primarily due to differing treatment for deferral/reversal of wash

sales, deferred trustees expense, capital loss carryforwards, and recognition of unrealized appreciation (depreciation) for certain derivative investments. To the extent these differences are permanent, reclassifications are made among the components of the Fund’s net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. Net investment income and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.

The tax character of distributions paid during the years indicated was as follows:


Year ended	February 29, 2012	February 28, 2011
Ordinary income	$5,176,907	$6,398,442

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:



Undistributed ordinary income	$	714,707
Unrealized appreciation		87,524,544

At February 29, 2012, the cost of investments for federal income tax purposes was $227,121,073 and the aggregate gross unrealized appreciation and depreciation based on that cost was:



Unrealized appreciation	$	88,838,548
Unrealized depreciation		(1,314,004	)

Net unrealized appreciation/depreciation	$	87,524,544



Year of Expiration	Amount
2017	$	8,601,528
2018		132,297,711

Total	$	140,899,239

For the year ended February 29, 2012, $55,172,188 was utilized.

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Act) was enacted, which changed

Columbia Large Cap Enhanced Core Fund

February 29, 2012

various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. Under the Act, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $216,344,045 and $358,707,510, respectively, for the year ended February 29, 2012.

Note 6. Lending of Portfolio Securities

At February 29, 2012, securities valued at $26,747,345 were on loan, secured by U.S. government securities valued at $27,590,215 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower’s failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Note 7. Custody Credits

Columbia Large Cap Enhanced Core Fund

February 29, 2012

Note 8. Affiliated Money Market Fund

Effective June 27, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as “Dividends from affiliates” in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 9. Shareholder Concentration

At February 29, 2012, one unaffiliated shareholder account owned 89.3% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 10 . Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on June 27, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period June 27, 2011 through December 12, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess.

Prior to March 28, 2011, the collective borrowing amount of the credit facility was $280 million. Interest was charged to each fund based on its borrowings at a rate equal to the greater of the (i) federal funds rate plus 1.25% per annum or (ii) the overnight LIBOR rate plus 1.25% per annum.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Large Cap Enhanced Core 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 Large Cap Enhanced Core Fund (the “Fund”) (a series of Columbia Funds Series Trust), at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for the two years in the period then ended and the financial highlights for each of 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 February 29, 2012 by correspondence with the custodian, brokers and transfer agent provide a reasonable basis for our opinion.

President’s Message

Dear Shareholders,

U.S. economic data surprised on the upside and fears of recession abated. With the bar of expectations set low, investors responded positively to the announcement that the economy had expanded by 1.8% in the third quarter. Consumer confidence improved, even though consumers remain under pressure with no real increase in disposable income and a continued decline in household net worth. Headline inflation — which tracks a broad range of consumer expenditures, including food and energy — declined. Even manufacturing held its ground.

Against this backdrop, the U.S. equity markets logged solid returns. The S&P 500 Index gained 11.82%, moving into positive territory

for the year with quarterly advances in all ten sectors. Mid- and small-cap stocks did even better. Value outperformed growth across all market capitalizations. Energy stocks led the market, as the price of oil moved above $100 a barrel in December. Industrials and materials stocks rose, buoyed by improving economic data. The U.S. fixed-income markets logged modest but solid returns. High-yield bonds were the best performers as the economy showed signs of improvement. Emerging market bonds were strong performers, as inflation came under control in key regions. Municipal bonds and Treasuries eked out only modest gains, as investors moved away from quality in favor of riskier assets.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges/loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.)

Columbia Funds are distributed by Columbia Management Investment Distributors, Inc., member FINRA, and managed by Columbia Management Investment Advisers, LLC.

The “without sales charge” returns do not include the effect of sales charges. If they had, returns would be lower.

All results shown assume reinvestment of distributions. Class I, Class R4 and Class Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class I, Class R4 and Class Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund’s prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

Class B and Class R4 shares were initially offered by the Fund on March 7, 2011.

Class I shares were initially offered by the Fund on November 16, 2011.

The returns shown for periods prior to the share class inception date (including returns since inception, which are since fund inception) include the returns of the fund’s oldest share class. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable.

Understanding Your Expenses – Columbia Small Cap Index Fund

Analyzing your fund’s expenses

To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. 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 the period. See “Compare with other funds” below for details on how to use the hypothetical data.

For the 12-month period that ended February 29, 2012, the fund’s Class A shares returned 4.65% without sales charge. The S&P SmallCap 600 Index returned 5.14%. The fund seeks to allocate fund assets among common stocks in approximately the same weightings of the S&P SmallCap 600 Index. As such, its return was in line with the return of the index, after fees and expenses, which the index does not incur.

U.S. economy picks up momentum

Defensive sectors drove returns

For the 12-month period, the health care, utilities and consumer staples sectors generated the highest returns. However, health care, consumer discretionary and financials were the top three contributors to returns, based on sector weights, in both the fund and the index. Pharmaceuticals, distributors, biotechnology, containers & packaging and Internet software & services were the leading industry gainers. The top three individual securities within the index and the fund were in the health care sector: Questcor Pharmaceuticals (0.5% of net assets), HealthSpring and Regeneron Pharmaceuticals (positions eliminated).

Telecommunication services, energy and information technology were the weakest sector performers for the period. Automobiles, media, real estate management & development, capital markets and metals & mining logged the most disappointing results within industry groups. TriQuint Semicondutor, Veeco Instruments and ION Geophysical (0.2%, 0.2% and 0.2% of net assets, respectively) were the worst-performing individual securities in the index and the fund for the period.

There were 59 additions and deletions to the index during the 12-month period. Since the fund is mandated to track the underlying benchmark, all changes that were made to the index were also made to the fund.

The fund owned equity index futures contracts in the notional amount of its cash balances during the period. It does so in order to keep its investment exposure on par with the index, which is always fully invested.

Fair Value Measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

Level 2 – Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

Level 3 – Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Columbia Small Cap Index Fund

Futures and options on futures contracts are valued based upon the settlement price established each day by the board of trade or exchange on which they are traded.

Derivative Instruments

Futures Contracts

Futures contracts represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund

bought and sold futures contracts to maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. Upon entering into futures contracts, the Fund bears risks which may include interest rates, exchange rates or securities prices moving unexpectedly, in which case, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Effects of Derivative Transactions in the Financial Statements

The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; the impact of derivative transactions on the Fund’s operations over the period including realized gains or losses and unrealized gains or losses. The derivative schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Fund, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

The Fund receives distributions from holdings in real estate investment trusts (REITs) which report information on the character of their distributions annually. REIT distributions are allocated to dividend income, capital gain and return of capital based on estimates made by the Fund’s management if actual information has not yet been reported. Return of capital is recorded as a reduction of the cost basis of securities held. Management’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs which could result in a proportionate increase in return of capital to shareholders.

Expenses

Determination of Class Net Asset Value

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 (including net short-term capital gains), 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 from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed

Columbia Small Cap Index Fund

February 29, 2012

along with the income dividend. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations which may differ from GAAP.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc.

(Ameriprise Financial), determines which securities will be purchased, held or sold. The management fee is an annual fee that is equal to 0.10% of the Fund’s average daily net assets.

Administration Fees

Pricing and Bookkeeping Fees

Other Fees

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred

Columbia Small Cap Index Fund

February 29, 2012

Compensation Plan (the Plan), the Board members who are not “interested persons” of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund’s expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Transfer Agent Fees

The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Fund. The transfer agent fees for the Fund are payable by the Investment Manager. The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses.

Plan Administration Fees

Under a Plan Administration Services Agreement with the Transfer Agent, the Fund pays an annual fee at a rate of 0.25% of the Fund’s average daily net assets attributable to Class R4 shares for the provision of various administrative, recordkeeping, communication and educational services.

Distribution and Service Fees

The Plans require the payment of a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. The Plans also required the payment of a monthly service fee at the maximum annual rate of 0.25% of the average daily net assets attributable to Class B shares of the Fund and the payment of a monthly distribution fee at the maximum annual rate of 0.75% of the average daily net assets attributable to Class B shares of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $6,291 for Class B shares for the year ended February 29, 2012.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective April 30, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rates as a percentage of the class’ average daily net assets:



Class A	0.45	%
Class B	1.20
Class I	0.20
Class R4	0.45
Class Z	0.20

Under the agreement, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be

Columbia Small Cap Index Fund

February 29, 2012

paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, extraordinary expenses and any other expenses the exclusion of which is specifically approved by the Board. This agreement may be modified or amended only with approval from all parties.

Prior to April 30, 2011, the Investment Manager voluntarily agreed to reimburse a portion of the Fund’s expenses (excluding certain expenses, such as distribution and services fees, brokerage commissions, interest, taxes and extraordinary expenses, but including custodian charges relating to overdrafts, if any) so that the Fund’s ordinary net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, did not exceed 0.20% of the Fund’s average daily net assets on an annualized basis.

Prior to May 1, 2011, the Investment Manager was entitled to recover from the Fund any fees waived and/or expenses reimbursed for a three year period following the date of such fee waiver and/or reimbursement under these arrangements if such recovery did not cause the Fund’s expenses to exceed the expense limitations in effect at the time of recovery. Effective May 1, 2011, the Investment Manager has eliminated such fee recoupment provisions.

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for deferred trustees expense, deferral/reversal of wash sales, recognition of unrealized appreciation (depreciation) of certain derivative instruments, capital loss carryforwards and distributions. To the extent these differences are permanent, reclassifications are made among the components of the Fund’s net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:



Undistributed Net Investment Income	$	79,959
Accumulated Net realized Loss		48,263
Paid-In Capital		(128,222	)

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

The tax character of distributions paid during the years indicated was as follows:


	Year ended February 29, 2012		Year ended February 28, 2011
Ordinary income		$22,262,162		$15,358,414
Long-term capital gains		101,946,466		9,598,829

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:



Undistributed ordinary income	$	301,418
Undistributed long-term capital gains		53,802,014
Unrealized appreciation		401,048,627

At February 29, 2012, the cost of investments for federal income tax purposes was $1,977,407,541 and the aggregate gross unrealized appreciation and depreciation based on that cost was:



Unrealized appreciation	$	575,012,470
Unrealized depreciation	$	(173,963,843	)

Net unrealized appreciation	$	401,048,627

Columbia Small Cap Index Fund

February 29, 2012

Columbia Small Cap Index Fund acquired capital loss carryforwards in connection with the merger with RiverSource Small Company Index Fund of 10,841,431 (Note 12). In addition to the acquired capital loss carryforwards, the Fund also acquired unrealized capital gains as a result of the merger. These acquired capital loss carryforwards were utilized in full during the current fiscal year.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $407,592,877 and $433,679,970, respectively, for the year ended February 29, 2012.

Note 6. Regulatory Settlements

During the February 29, 2012, the Fund received $20,242 as a result of a settlement of an administrative proceeding brought by the Securities and Exchange Commission against an unaffiliated third party relating to market timing and/or late trading of mutual funds which represented the Fund’s portion of the proceeds from the settlement (the Fund was not a party to the proceeding). The proceeds received by the Fund were recorded as an increase to additional paid-in capital.

Note 7. Lending of Portfolio Securities

Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned.

At February 29, 2012, securities valued at $67,724,348 were on loan, secured by cash collateral of $71,062,267 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower’s failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

Note 8. Custody Credits

Columbia Small Cap Index Fund

February 29, 2012

invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement. Subsequent to this date, the Fund may invest its daily balance in an affiliated money market fund as detailed below. For the period March 1, 2011 through March 27, 2011, there were no custody credits.

Note 9. Affiliated Money Market Fund

Effective March 28, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as “Dividends from affiliates” in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 10. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned an aggregate of 44.4% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 11. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility became effective on March 28, 2011, replacing a prior credit facility. The credit facility agreement, as amended, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager, severally and not jointly, permits collective borrowings up to $500 million. Pursuant to a December 13, 2011 amendment to the credit facility agreement, interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the overnight federal funds rate plus 1.00% or (i) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period March 28, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal

funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess. The Fund also paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.10% per annum.

The Fund had no borrowings during the year ended February 29, 2012.

Note 12. Fund Merger

At the close of business on June 3, 2011, the Fund acquired the assets and assumed the identified liabilities of RiverSource Small Company Index Fund. The reorganization was completed after shareholders approved the plan on February 15, 2011. The purpose of the transaction was to combine two funds managed by the Investment Manager with comparable investment objectives and strategies.

The aggregate net assets of the Fund immediately before the acquisition were $1,858,175,305 and the combined net assets immediately after the acquisition were $2,258,332,592.

The merger was accomplished by a tax-free exchange of 77,975,673 shares of RiverSource Small Company Index Fund valued at $400,157,287 (including $76,110,521 of unrealized appreciation).

In exchange for the RiverSource Small Company Index Fund shares, the Fund issued the following number of shares:



	Shares
Class A		20,611,091
Class B		1,666,330
Class R4		558,110

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, RiverSource Small Company Index Fund’s cost of investments was carried forward.

Columbia Small Cap Index Fund

February 29, 2012

The financial statements reflect the operations of the Fund for the period prior to the merger and the combined Fund for the period subsequent to the merger. Because the combined investment portfolios have been managed as a single integrated portfolio since the merger was completed, it is not practicable to separate the amounts of revenue and earnings of RiverSource Small Company Index Fund that have been included in the combined Fund’s Statement of Operations since the merger was completed.

Assuming the merger had been completed on March 1, 2011 the Fund’s pro-forma net investment income, net realized gain, net change in unrealized depreciation and net increase in net assets resulting from operations for the year ended February 29, 2012 would have been approximately $19.4 million, $134.7 million, $(48.4) million and $105.7 million, respectively.

neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as necessary, 8-K filings with the Securities and Exchange Commission on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.

There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased fund

redemptions, reduced sale of fund shares or other adverse consequences to the Funds. Further, although we believe proceedings are not likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Small Cap 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 Small Cap Index Fund (the “Fund”) (a series of Columbia Funds Series Trust ) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

President’s Message

LOGO

Dear Shareholders,

U.S. economic data surprised on the upside and fears of recession abated. With the bar of expectations set low, investors responded positively to the announcement that the economy had expanded by 1.8% in the third quarter. Consumer confidence improved, even though consumers remain under pressure with no real increase in disposable income and a continued decline in household net worth. Headline inflation — which tracks a broad range of consumer expenditures, including food and energy — declined. Even manufacturing held its ground.

Against this backdrop, the U.S. equity markets logged solid returns. The S&P 500 Index gained 11.82%, moving into positive territory

President, Columbia Funds

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges/loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.)

Columbia Funds are distributed by Columbia Management Investment Distributors, Inc., member FINRA, and managed by Columbia Management Investment Advisers, LLC.

Class I shares commenced operations on September 27, 2010.

All results shown assume reinvestment of distributions. Class A shares are sold at net asset value. Class I shares and Z shares are sold at net asset value with no distribution and service (Rule 12b-1) fees. Class I shares and Z shares have limited eligibility and the investment minimum requirements may vary. Please see the fund’s prospectuses for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

The tables do not reflect the deduction of taxes that a shareholder may pay on fund distributions or on the redemption of fund shares.

The returns shown for periods prior to the share class inception date (including returns since inception, which are since Fund inception) include the returns of the Fund’s Class Z shares, the fund’s oldest share class. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable.

Understanding Your Expenses – Columbia Mid Cap Index Fund

Analyzing your fund’s expenses

To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated 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. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the Actual column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. 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 the period. See “Compare with other funds” below for details on how to use the hypothetical data.

Compare with other funds


September 1, 2011 – February 29, 2012

	Account value at the beginning of the period ($)				Account value at the end of the period ($)				Expenses paid during the period ($)				Fund’s annualized expense ratio (%)

Class A		1,000.00		1,000.00		1,123.00		1,022.63		2.38		2.26		0.45

Class Z		1,000.00		1,000.00		1,125.00		1,023.87		1.06		1.01		0.20

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.

Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

For the 12-month period that ended February 29, 2012, the fund’s Class A shares returned 2.12% without sales charge. The fund’s benchmark, the S&P MidCap 400 Index, returned 2.55%. The fund seeks to allocate its assets among common stocks in approximately the same weightings as the S&P MidCap 400 Index. As such, its return was in line with the return of the index, after fees and expenses, which the index does not incur.

U.S. economy picks up momentum

Economic growth benefited key sectors

As economic growth picked up, consumer staples, consumer discretionary and materials sectors generated the highest gains within the benchmark and the fund. Consumer discretionary, industrials and consumer staples made the largest contributions to return, based on the weight of these sectors in the benchmark and the fund. Beverages, multiline retail, leisure equipment & products, distributors and trading companies were the leading industry groups. The top performing mid-cap securities for the period included Dollar Tree, Monster Beverage, Regeneron Pharmaceuticals, Tractor Supply and Equinix (a provider of carrier-neutral data centers and Internet exchanges) (position eliminated, 0.7%, 0.7%, 0.5% and 0.6% of net assets, respectively).

Energy, information technology and financials were the three biggest laggards for the period. Air freight & logistics, auto components, communications equipment, thrift & mortgage finance and paper & forest products were the bottom five industries, as measured by total return. Arch Coal, Cimarex Energy, Cree (a maker of indoor and light-emitting diode (LED) indoor and outdoor lighting and other applications), Rovi (digital entertainment technology solutions) and Forest Oil (0.2%, 0.6% 0.3%, 0.3% and 0.1% of net assets, respectively) were the weakest performing securities for the period.

There were 40 additions and deletions to the index during the 12-month period. All changes that were made to the index were also made to the fund.

Portfolio Manager’s Report (continued) – Columbia Mid Cap Index Fund

The fund owned equity index futures contracts in the notional (face value) amount of its cash balances during the period. It does so in order to keep its investment exposure on par with the index, which is always fully invested.

Looking ahead

Equity securities are subject to stock market fluctuations that occur in response to economic and business developments.

Stocks of mid-cap companies pose special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Fair Value Measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

The Accompanying Notes to Financial Statements are an integral part of this statement.

Columbia Mid Cap Index Fund

February 29, 2012

Fair Value Measurements (continued)

Fair value inputs are summarized in the three broad levels listed below:

Level 2 – Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

Level 3 – Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

The following table is a summary of the inputs used to value the Fund’s investments as of February 29, 2012:

Notes to Financial Statements – Columbia Mid Cap Index Fund

February 29, 2012

Note 1. Organization

Columbia Mid Cap Index Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

Fund Shares

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class I and Class Z shares. All share classes have identical voting, dividend and liquidation rights. Each share class has its own expense structure and sales charges, as applicable.

Class A shares have no sales charge.

Class I shares are not subject to sales charges and are only available to the Columbia Family of Funds.

Class Z shares are not subject to sales charges, and are only available to certain investors, as described in the Fund’s prospectus.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements.

Security Valuation

Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If any foreign share prices are not readily available as a result of limited share activity the securities are valued at the mean of the latest quoted bid and asked prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. However, many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to the policy adopted by the Board of Trustees (the Board), including utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in other open-end investment companies, including money market funds, are valued at net asset value.

Futures and options on futures contracts are valued based upon the settlement price established each day by the board of trade or exchange on which they are traded.

Columbia Mid Cap Index Fund

February 29, 2012

Derivative Instruments

Futures Contracts

payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.

Effects of Derivative Transactions in the Financial Statements

The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; the impact of derivative transactions on the Fund’s operations over the period including realized gains or losses and unrealized gains or losses. The derivative schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

		Contracts Opened
Futures Contracts		7,691

Repurchase Agreements

The Fund may engage in repurchase agreement transactions with institutions that management has determined are creditworthy. The Fund, through the custodian, receives delivery of the underlying securities collateralizing a repurchase agreement. Management is responsible for determining that the 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 in or restrictions on a 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.

Security Transactions

Income Recognition

Interest income is recorded on the accrual basis.

The Fund receives distributions from holdings in real estate investment trusts (REITs) which report information on the character of their distributions annually. REIT distributions are allocated to dividend income, capital gain and return of capital based on estimates made by the Fund’s management if actual information has not yet been reported. Return of capital is recorded as a reduction of the cost basis of securities held. Management’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs which could result in a proportionate increase in return of capital to shareholders.

Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the

payment date. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains.

Expenses

Determination of Class Net Asset Value

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 (including net short-term capital gains), 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.

Recent Accounting Pronouncement

Fair Value Measurements and Disclosures

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Administration Fees

Pricing and Bookkeeping Fees

Prior to July 25, 2011, the Fund had entered into a Financial Reporting Services Agreement (the Financial Reporting Services

Agreement) with State Street Bank and Trust Company (State Street) and the Investment Manager pursuant to which State Street provided financial reporting services to the Fund. The Fund also entered into an Accounting Services Agreement (collectively with the Financial Reporting Services Agreement, the State Street Agreements) with State Street and the Investment Manager pursuant to which State Street provided accounting services to the Fund. Under the State Street Agreements, the Fund paid 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. The aggregate fee did not exceed $140,000 per year (exclusive of out-of-pocket expenses and charges). The Fund also reimbursed State Street for certain out-of-pocket expenses and charges. Effective July 25, 2011, these services are provided under the Administrative Services Agreement discussed above.

Other Fees

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not “interested persons” of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Compensation of Chief Compliance Officer

The Board has appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. Effective April 1, 2011, the Fund’s expenses associated with the Chief Compliance Officer are paid directly by the Investment Manager. Prior to April 1, 2011, the Fund, along with other affiliated funds, paid its pro-rata share of the expenses for the Chief Compliance Officer. Such fees did not exceed $15,000 per year.

Columbia Mid Cap Index Fund

February 29, 2012

Transfer Agent Fees

The Transfer Agent receives monthly account-based service fees based on the number of open accounts and is reimbursed by the Fund for the fees and expenses the Transfer Agent pays to financial intermediaries that maintain omnibus accounts with the Fund that is a percentage of the average aggregate value of the Fund’s shares maintained in each such omnibus account (other than omnibus accounts for which American Enterprise Investment Services Inc. is the broker of record or accounts where the beneficial shareholder is a customer of Ameriprise Financial Services, Inc., which are paid a per account fee). The Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket expenses. Class I shares do not pay transfer agent fees.

For the year ended February 29, 2012, the Fund’s effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:



Class A	0.19	%
Class Z	0.19

Distribution and Service Fees

under the 1940 Act, the Board has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

Effective July 1, 2011, the Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below), through June 30, 2012, unless sooner terminated at the sole discretion of the Board, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rates as a percentage of the class’ average daily net assets:



Class A	0.45	%
Class I	0.19
Class Z	0.20

Class A	0.45	%
Class I	0.19
Class Z	0.20

Note 4. Federal Tax Information

For the year ended February 29, 2012, these differences are primarily due to differing treatment for distribution reclassifications, redemption-based payments treated as eligible for the dividends paid deduction, futures contracts, and deferral/reversal of wash sale losses. To the extent these differences are permanent; reclassifications are made among the components of the Fund’s net assets in the Statement of Assets and Liabilities. Temporary differences do not require reclassifications. In the Statement of Assets and Liabilities the following reclassifications were made:



Undistributed net investment income	$	(371,196	)
Accumulated net realized gain		(7,040,063	)
Paid-in capital		7,411,259

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

	Year ended February 29, 2012		Year ended February 28, 2011
Ordinary income	$	36,747,997	$	23,786,031
Long-term capital gains		115,909,747		10,988,856

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At February 29, 2012, the components of distributable earnings on a tax basis were as follows:



Undistributed ordinary income	$	1,346,378
Undistributed long-term capital gains		36,952,014
Unrealized appreciation		596,097,937

At February 29, 2012, the cost of investments for federal income tax purposes was $2,432,279,509 and the aggregate gross unrealized appreciation and depreciation based on that cost was:



Unrealized appreciation	$	799,931,009
Unrealized depreciation	$	(203,833,072	)

Net unrealized appreciation	$	596,097,937

Note 6. Lending of Portfolio Securities

Effective July 25, 2011, the Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan

Columbia Mid Cap Index Fund

February 29, 2012

Chase Bank, N.A. (JPMorgan). The Agreement, which replaces the previous security lending arrangement with State Street, authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is requested to be delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At February 29, 2012, securities valued at $40,051,650 were on loan, secured by cash collateral of $41,746,464 (which does not reflect calls for collateral made to borrowers by JPMorgan at period end) that is partially or fully invested in short-term securities or other cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower’s failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. The Investment Manager is not responsible for any losses incurred by the Fund in connection with the securities lending program. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments.

collateral. The income generated by the investment of the collateral, net of any fees remitted to State Street as the lending agent and borrower rebates, was paid to the Fund.

Note 7. Custody Credits

Note 8. Affiliated Money Market Fund

Effective July 25, 2011, the Fund may invest its daily cash balances in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as “Dividends from affiliates” in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 9. Shareholder Concentration

At February 29, 2012, two unaffiliated shareholder accounts owned an aggregate of 51.9% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts of these accounts may have a significant effect on the operations of the Fund.

The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.08% per annum. For the period July 25, 2011 through December 13, 2011, interest was charged to each participating fund based on its borrowings at a rate equal to the sum of the federal funds rate plus (i) 1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the amount of such excess.

Report of Independent Registered Public Accounting Firm

To the Trustees of Columbia Funds Series Trust and the Shareholders of Columbia Mid Cap 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 Mid Cap Index Fund (the “Fund”) (a series of Columbia Funds Series Trust) at February 29, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 February 29, 2012 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

(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. As set forth in this Fund Policy, a service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund’s independent auditor; provided, however, that pre-approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC’s rules 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.

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund’s Treasurer or other Fund Officer shall submit to the Audit Committee a schedule of the types of Fund Services and Fund-related Adviser Services that are subject to specific pre-approval.

This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre-approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of pre-approved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit Committee is in agreement with the types of services that the independent accountants will be permitted to perform.

The Fund’s Treasurer or other Fund Officer 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 with forecasted fees for the annual period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor with actual fees during the current reporting period.

*****

(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 February 29, 2012 and February 28, 2011 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 February 29, 2012 and February 28, 2011 are approximately as follows:

2012		2011
$	632,100	$	702,200

(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.

Not applicable.

Item 11. Controls and Procedures.

(a) The registrant’s principal executive officer and principal financial officers, based on their evaluation of the registrant’s disclosure controls and procedures as of a date within 90 days of the filing of this report, have concluded that such controls and procedures are adequately designed to ensure that material information required to be disclosed by the registrant in Form N-CSR is accumulated and communicated to the registrant’s management, including the principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) There was no change in the registrant’s internal control over financial reporting that occurred during the registrant’s second fiscal quarter of the period covered by this report that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting.
