President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, 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. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

The BofAML All Convertibles All Qualities Index measures the performance of U.S. dollar-denominated convertible securities not currently in bankruptcy with a total market value greater than $50 million at issuance.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Convertible Securities Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

Columbia Management Investment Advisers, LLC and/or certain of its affiliates have contractually agreed to waive certain fees and to reimburse certain expenses until June 30, 2014, unless sooner terminated at the sole discretion of the Fund's Board, such that net expenses (excluding fees and expenses of acquired funds) will not exceed 0.66% for Class I. Any amounts waived will not be reimbursed by the Fund. This change was effective July 1, 2013. If this change had been in place for the entire six month period ended August 31, 2013, the actual expenses paid would have been $3.45 and the hypothetical expenses paid would have been $3.35 for Class I.

Other share classes may have had expense waiver changes; however, the changes were not considered material.

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.

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.

Portfolio of Investments (continued)

August 31, 2013 (Unaudited)

Fair Value Measurements (continued)

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

The Fund's assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain Convertible Bonds classified as Level 3 are valued using a market approach. To determine fair value for these securities, management considered various factors which may have included, but were not limited to, the halt price of the security, the movement in observed market prices for other securities from the issuer, the movement in certain foreign or domestic market indices, and the estimated earnings of the respective company and market multiples derived from a set of comparable companies. Significant increases (decreases) to any of these inputs would result in a significantly lower (higher) fair value measurement. Generally, a change in estimated earnings of the respective company may result in a change to the comparable companies and market multiples utilized.

Transfers in and/or out of Level 3 are determined based on the fair value at the beginning of the period for security positions held throughout the period.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Convertible Securities Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Convertible Securities 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 R4, Class R5, Class W and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

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

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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

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.

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 ask prices on such exchanges or markets.

Semiannual Report 2013
29



Columbia Convertible Securities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

Foreign equity 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 ask 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 or market, 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 open-end investment companies, including money market funds, are valued at net asset value.

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 fair value.

Delayed Delivery Securities

The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a "when-issued" basis. This may increase the risk if the other party to the transaction fails to deliver and causes the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.

Equity-Linked Notes

The Fund may invest in equity-linked notes (ELNs). An ELN is a debt instrument whose value is based on the value of a single equity security, basket of equity securities or an index of equity securities (each, an Underlying Equity). An ELN typically provides interest income, thereby offering a yield advantage over investing directly in an Underlying Equity. However, the holder of an ELN may have limited or no benefit from any appreciation in the Underlying Equity, but is exposed to various risks, including, without limitation, volatility, issuer and market risk. The Fund may purchase ELNs that trade on a securities exchange or those that trade on the over-the-counter markets, including securities offered and sold under Rule 144A of the Securities Act of 1933, as amended. The Fund may also purchase an ELN in a privately negotiated transaction with the issuer of the ELN (or its broker-dealer affiliate).

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

Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. For convertible securities, premiums attributable to the conversion feature are not amortized.

Corporate actions and dividend income are generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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

Notes to Financial Statements (continued)

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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

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

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 investment management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.76% to 0.62% as the Fund's net assets increase. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.75% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.05% as the Fund's net assets increase. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.06% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $1,643.

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred

Semiannual Report 2013

Columbia Convertible Securities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.25

%

 

Class B

   

0.25

   

Class C

   

0.25

   

Class R

0.25

   

Class R5

   

0.05

   

Class W

   

0.25

   

Class Z

   

0.25

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $1,710.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rates of 0.75%, 0.75% and 0.50% of the average daily net assets attributable to Class B, Class C and Class R shares of the Fund.

The Fund may pay a distribution fee 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 $67,831 for Class A, $213 for Class B, $160 for Class C, shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $547,185,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $214,716,106 and $208,335,076, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 32.2% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Affiliated shareholder accounts owned 44.3% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A.

whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Convertible Securities Fund

Approval of Investment Management
Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Convertible Securities Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013

Columbia Convertible Securities Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe's median expense ratio. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Not FDIC insured • No bank guarantee • May lose value



President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, 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. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

Columbia Large Cap Core Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing,

including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Large Cap Core Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Large Cap 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

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class I, Class R5, Class W and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class W shares are not subject to sales charges and are available only to investors purchasing through authorized

investment programs managed by investment professionals, including discretionary managed account programs.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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

Semiannual Report 2013
21



Columbia Large Cap Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, 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 open-end investment companies, including money market funds, are valued at net asset value.

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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

Semiannual Report 2013
22



Columbia Large Cap Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.70% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.06% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $1,710.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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

Semiannual Report 2013
23



Columbia Large Cap Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

out-of-pocket fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares.

For the six months ended August 31, 2013, the Fund's annualized 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 R5

   

0.05

   

Class W

   

0.21

   

Class Z

   

0.20

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $4,440.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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% and 0.25% of the average daily net assets attributable to Class B, Class C and Class W shares of the Fund.

The Fund may pay a distribution fee 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 $19,167 for Class A, $338 for Class B and $46 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $477,505,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $654,834,390 and $802,115,599, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 52.0% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Affiliated shareholder accounts owned 24.2% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A.

whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. Information Regarding Pending and Settled Legal Proceedings

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.

Semiannual Report 2013
25



Columbia Large Cap Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia Large Cap Core Fund

Approval of Investment Management
Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Large Cap Core Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Approval of Investment Management
Services Agreement
(continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe's median expense ratio. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The Russell 3000 Index, an unmanaged index, measures the performance of the 3,000 largest U.S. companies based on total market capitalization, which represents approximately 98% of the investable U.S. equity market.

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment vehicles (including mutual funds and exchange-traded funds).

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.

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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Marsico 21st Century Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Marsico 21st 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, Class R4 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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.

Semiannual Report 2013

Columbia Marsico 21st Century Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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

Semiannual Report 2013
21



Columbia Marsico 21st Century Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadviser (see Subadvisory Agreement below) has the primary responsibility for the day-to-day portfolio management of the Fund. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.68% 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 investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.06% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $2,303.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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

Columbia Marsico 21st Century Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 fees.

For the six months ended August 31, 2013, the Fund's annualized 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 R

   

0.20

   

Class R4

   

0.20

   

Class Z

   

0.20

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $1,600.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rates of 0.75%, 0.75% and 0.50% of the average daily net assets attributable to Class B, 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 $52,404 for Class A, $21,552 for Class B and $1,690 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $777,622,000 and the

Unlimited capital loss carryforwards are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date 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. The Fund has elected to treat late year ordinary losses of $2,781,701 at February 28, 2013 as arising on March 1, 2013.

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 $500,239,983 and $666,502,097, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 16.5% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Affiliated shareholder accounts owned 16.3% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

For the six months ended August 31, 2013, the average daily loan balance outstanding on days when borrowing existed was $3,828,571 at a weighted average interest rate of 1.20%. Interest expense incurred by the Fund is recorded as interest expense in the Statement of Operations.

Note 9. Significant Risks

Consumer Discretionary Risk

The Fund's portfolio managers may invest significantly in issuers operating in the consumer discretionary sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

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.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds.

and Subadvisory Agreements
(continued)

Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser, which is unaffiliated with the Investment Manager, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality, subject to Columbia Management's ongoing heightened scrutiny of the Subadviser's organization and performance.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that performance was appropriate in light of the particular management style involved and the particular market environment.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for selecting and monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board took into account management's view that the Fund's relative underperformance reflected the interrelationship of market conditions with the particular investment strategies employed by the Marsico team. The Board observed that the Subadviser was subject to Columbia Management's ongoing heightened scrutiny of its performance.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Understanding Your Fund's Expenses

(Unaudited)

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.

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

Fair Value Measurements (continued)

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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Marsico Growth Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Marsico Growth 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 R4, Class R5, Class W and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

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

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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,

Semiannual Report 2013
23



Columbia Marsico Growth Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The

amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadviser (see Subadvisory Agreement below) has the primary responsibility for the day-to-day portfolio management of the Fund. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.64% 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 investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.05% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $3,906.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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).

Semiannual Report 2013
25



Columbia Marsico Growth Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

The Transfer Agent also receives compensation from fees for various shareholder services and reimbursements for certain out-of-pocket fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.21

%

 

Class B

   

0.21

   

Class C

0.21

   

Class R5

   

0.05

   

Class W

   

0.21

   

Class Z

   

0.21

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $2,461.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 of the Fund.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Fund shares were $107,210 for Class A, $4,903 for Class B and $4,311 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $1,463,258,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $1,055,215,200 and $1,570,305,719, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, three unaffiliated shareholder accounts owned an aggregate of 62.7% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

For the six months ended August 31, 2013, the average daily loan balance outstanding on days when borrowing existed was $13,316,667 at a weighted average interest rate of 1.19%. Interest expense incurred by the Fund is recorded as interest expense in the Statement of Operations.

Note 9. Significant Risks

Consumer Discretionary Risk

The Fund's portfolio managers may invest significantly in issuers operating in the consumer discretionary sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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

Semiannual Report 2013
27



Columbia Marsico Growth Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia Marsico Growth Fund

Approval of Investment Management Services and Subadvisory Agreements

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Marsico Growth Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Marsico Capital Management, LLC (the Subadviser), the Subadviser has provided portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

Columbia Marsico Growth Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser which is unaffiliated with the Investment Manager, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality, subject to Columbia Management's ongoing heightened scrutiny of the Subadviser's organization and performance.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed the Fund's performance was appropriate in light of the particular management style involved and the particular market environment.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for selecting and monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board observed that management was exploring ways in which to improve the performance of the Fund. The Board took into account management's view that the Fund's relative underperformance reflected the interrelationship of market conditions with the particular investment strategies employed by the Marsico team. The Board observed that the Subadviser was subject to Columbia Management's ongoing heightened scrutiny of its performance.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including,

Columbia Marsico Growth Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

Columbia Mid Cap Index Fund

Portfolio of Investments (continued)

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Columbia Mid Cap Index Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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, Class R5 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 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. 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 fair value.

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 (making it difficult for the Fund to sell, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on over-the-counter (OTC) derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives

Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is an agreement between a Fund and a counterparty that governs OTC derivatives and forward foreign currency exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Fund would consider terminating the derivative contracts

Columbia Mid Cap Index Fund

Notes to Financial Statements (continued)

based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Futures Contracts

Futures contracts are exchange traded and 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. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it 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. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. 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.

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 over the period in the Statement of Operations 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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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

Notes to Financial Statements (continued)

reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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 at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment management fee is an annual fee that is equal to 0.10% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.10% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $4,859.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.19

%

 

Class R5

   

0.05

   

Class Z

   

0.19

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $160.

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.

Under the Plans, the Fund pays 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.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the period disclosed below, 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:

    Fee Rates Contractual
through
June 30, 2014
 

Class A

   

0.45

%

 

Class I

   

0.20

   

Class R5

   

0.20

   

Class Z

   

0.20

   

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $2,260,757,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $554,689,525 and $114,840,039, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 24.3% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. Significant Risks

Financial Sector Risk

The Fund's portfolio managers may invest significantly in issuers operating in the financial sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia Mid Cap Index Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Mid Cap Index Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013

Columbia Mid Cap Index Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, 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. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

The MSCI EAFE (Europe, Australasia, Far East) Index (Net) is a free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. The index is compiled from a composite of securities markets of Europe, Australasia and the Far East and is widely recognized by investors in foreign markets as the measurement index for portfolios of non-North American securities.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Multi-Advisor International Equity Fund

Understanding Your Fund's Expenses

(Unaudited)

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.

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.

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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Derivative instruments are valued at unrealized appreciation (depreciation).

(a)  Change in unrealized appreciation (depreciation) relating to securities held at August 31, 2013 was $(6,995).

The Fund does not hold any significant investments with unobservable inputs which are categorized as Level 3.

The Fund's assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain common stocks classified as Level 3 securities are valued using the market approach. To determine fair value for these securities, management considered various factors which may have included, but were not limited to, the halt price of the security, the movement in observed market prices for other securities from the issuer, the movement in certain foreign or domestic market indices, and the position of the security within the respective company's capital structure. Significant increases (decreases) to any of these inputs would result in a significantly lower (higher) fair value measurement.

Transfers in and/or out of Level 3 are determined based on the fair value at the beginning of the period for security positions held throughout the period.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Multi-Advisor International Equity 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 K, Class R, Class R4, Class R5, Class W, Class Y and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class K shares are not subject to sales charges, however this share class is closed to new investors.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class W shares are not subject to sales charges and are available only 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 generally available only to certain retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 and exchange traded funds (ETFs) are valued at the close of business of the New York Stock Exchange (NYSE). Equity securities and ETFs 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 ask prices on such exchanges or markets.

Foreign equity 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 ask prices on such

Semiannual Report 2013
34



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 or market, 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 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.

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 fair value.

Foreign Currency Transactions and Translations

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 (making it difficult for the Fund to sell, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on over-the-counter (OTC) derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets,

Semiannual Report 2013
35



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is an agreement between a Fund and a counterparty that governs OTC derivatives and forward foreign currency exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to

maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Fund would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are OTC agreements between two parties to buy and sell a currency at a set price on a future date. These contracts are typically 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 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. These instruments may be used for other purposes in future periods.

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 expires or 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.

Futures Contracts

Futures contracts are exchange traded and 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 manage exposure to the securities market, and maintain appropriate equity market exposure while keeping

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

sufficient cash to accommodate daily redemptions. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it 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. The initial margin deposit must be maintained at an established level over the life of the

contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. 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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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

Semiannual Report 2013
38



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadvisor (see Subadvisory Agreement below) shares the responsibility for the day-to-day portfolio management of the Fund with the Investment Manager. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.77% of the Fund's average daily net assets.

Subadvisory Agreements

The Investment Manager has entered into a Subadvisory Agreement with Threadneedle International Limited (Threadneedle) to subadvise a portion of the Fund's assets. The Investment Manager compensates Threadneedle to manage the investment of the Fund's assets. Prior to May 20, 2013, Marsico Capital Management, LLC (Marsico) was a subadviser to the Fund pursuant to a Subadvisory Agreement between the Investment Manager and Marsico. Threadneedle and Marsico each subadvised a portion of the Fund's assets. New investments in the Fund, net of any redemptions, were allocated in accordance with the Investment Manager's determination, subject to the oversight of the Board, of the allocation that was in the best interests of the shareholders. Threadneedle's and Marsico's proportionate share of investments in the Fund varied due to market fluctuations. Prior to May 20, 2013, the Investment Manager also compensated Marsico for its services as subadvisor. Marsico is not currently a subadviser to the Fund.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.08% to 0.05% as the Fund's net assets increase. The annualized effective

Semiannual Report 2013
39



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

administration fee rate for the six months ended August 31, 2013 was 0.08% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $2,163.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class K and Class R5 shares

are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to each share class. Beginning November 1, 2012, Class Y shares are not subject to transfer agent fees for at least twelve months.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.23

%

 

Class B

   

0.23

   

Class C

Class K

0.25

   

Class R5

   

0.05

   

Class W

   

0.23

   

Class Z

   

0.23

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $28,943.

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 K shares for the provision of various administrative, recordkeeping, communication and educational services.

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.

Under the Plans, the Fund pays 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. Also under the

Semiannual Report 2013
40



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

Plans, the Fund pays 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 of the Fund.

The Fund may pay a distribution fee 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 $42,357 for Class A, $1,073 for Class B and $174 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $724,170,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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. The Fund has elected to treat late year ordinary losses of $16,044,394 at February 28, 2013 as arising on March 1, 2013.

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 $639,849,431 and $733,377,860, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 21.7% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Affiliated shareholder accounts owned 38.3% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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

Semiannual Report 2013
42



Columbia Multi-Advisor International Equity Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia Multi-Advisor International Equity Fund

Board Consideration and Approval of Advisory Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Multi-Advisor International Equity Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Threadneedle International Limited (the Subadviser), an affiliate of Columbia Management, the Subadviser has provided portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

Board Consideration and Approval of Advisory Agreement (continued)

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser, the Board concluded that the services being performed under the Subadvisory Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance was appropriate in light of the particular management style involved and the particular market environment.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board observed that management was exploring ways in which to improve the performance of the Fund.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadvisers from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

Columbia Multi-Advisor International Equity Fund

Board Consideration and Approval of Advisory Agreement (continued)

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was slightly below the peer universe's median expense ratio shown in the reports. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Columbia Small Cap Index Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

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 may 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.

Fair Value Measurements (continued)

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

The following table is a summary of the inputs used to value the Fund's investments at August 31, 2013:

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Small Cap Index Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Small 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, Class K, Class R5 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 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 available only to the Columbia Family of Funds.

Class K shares are not subject to sales charges, however this share class is closed to new investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 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

Semiannual Report 2013
28



Columbia Small Cap Index Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 fair value.

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 excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts and market values of derivative instruments, if any, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer

accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs OTC derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Semiannual Report 2013

Columbia Small Cap Index Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Fund would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Futures Contracts

Futures contracts are exchange traded and 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. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it 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. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. 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.

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 over the period in the Statement of Operations 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.

Income Recognition

Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend

Columbia Small Cap Index Fund

Notes to Financial Statements (continued)

date or upon receipt of ex-dividend notification in the case of certain foreign securities.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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 at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment management fee is an annual fee that is equal to 0.10% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.10% of the Fund's average daily net assets.

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 and plan administration fees and any extraordinary non-recurring expenses that may arise, including litigation.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom

Semiannual Report 2013
31



Columbia Small Cap Index Fund

Notes to Financial Statements (continued)

and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $3,853.

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.

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 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 applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $3,677.

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 K shares for the provision of various administrative, recordkeeping, communication and educational services.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rates of 0.25% and 0.75%, respectively, 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 $982 for Class B shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the period disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $1,531,357,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $192,279,908 and $100,333,608, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 22.4% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. Significant Risks

Financial Sector Risk

The Fund's portfolio managers may invest significantly in issuers operating in the financial sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Small Cap Index Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Small Cap Index Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013

Columbia Small Cap Index Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Columbia Large Cap Enhanced Core Fund

Understanding Your Fund's Expenses

(Unaudited)

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 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 investment 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.

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.

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 may 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.

Fair Value Measurements (continued)

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific  or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Columbia Large Cap Enhanced Core Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class I, Class R, Class Y and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class Y shares are not subject to sales charges and are generally available only to certain retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 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. 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.

Columbia Large Cap Enhanced Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 fair value.

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 (making it difficult for the Fund to sell, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically

allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is an agreement between a Fund and a counterparty that governs OTC derivatives and forward foreign currency exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed

Semiannual Report 2013
21



Columbia Large Cap Enhanced Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Fund would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Futures Contracts

Futures contracts are exchange traded and 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. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it 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. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. 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.

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 over the period in the Statement of Operations

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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report

information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.69% of the Fund's average daily net assets.

Effective July 1, 2013, the Investment Manager has contractually agreed to waive 0.10% of the Fund's investment management fee through June 30, 2014. Prior to July 1, 2013, the Investment Manager contractually agreed to waive 0.15% of the Fund's investment management fee. The annualized effective investment management fee waiver for the six months ended August 31, 2013 was 0.13% of the Fund's average daily net assets.

Columbia Large Cap Enhanced Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

The annualized effective investment management fee rate, net of fee waivers, for the six months ended August 31, 2013 was 0.56% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.06% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expense include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $1,192.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Beginning November 1, 2012, Class Y shares are not subject to transfer agent fees for at least twelve months.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.21

%

 

Class R

   

0.21

   

Class Z

   

0.21

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $120.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays a monthly distribution fee at the maximum annual rate of 0.50% of the average daily net assets attributable to Class R shares of the Fund.

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $162,729,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation

 

$

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 $118,611,197 and $175,464,498, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 78.0% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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.

Semiannual Report 2013

Columbia Large Cap Enhanced Core Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Large Cap Enhanced Core Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Large Cap Enhanced Core Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013
27



Columbia Large Cap Enhanced Core Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe's median expense ratio. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Approval of Investment Management Services Agreement (continued)

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, 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. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

The S&P 500 Index, an unmanaged index, measures the performance of 500 widely held, large-capitalization U.S. stocks and is frequently used as a general measure of market performance.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Large Cap Index Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

Fair Value Measurements (continued)

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Large Cap Index Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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, Class R5 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 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 available only to the Columbia Family of Funds.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 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. 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 fair value.

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 (making it difficult for the Fund to sell, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is an agreement between a Fund and a counterparty that governs OTC derivatives and forward foreign currency exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk,

Semiannual Report 2013
27



Columbia Large Cap Index Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

the Fund would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Futures Contracts

Futures contracts are exchange traded and 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. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it 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. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. 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.

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 over the period in the Statement of Operations 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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the

Semiannual Report 2013
28



Columbia Large Cap Index Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment management fee is an annual fee that is equal to 0.10% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.10% of the Fund's average daily net assets.

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 and plan administration fees and any extraordinary non-recurring expenses that may arise, including litigation.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health

and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $4,573.

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.

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 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 applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $8,770.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays a monthly service fee and a monthly distribution fee at the maximum annual rates of 0.25% and 0.75%, respectively, of the average daily net assets attributable to Class B shares of the Fund.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the period disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

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 $36,388,726 and $33,620,080, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 17.4% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby

the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. Information Regarding Pending and Settled Legal Proceedings

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

Semiannual Report 2013

Columbia Large Cap Index Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

Columbia Large Cap Index Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Large Cap Index Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013

Columbia Large Cap Index Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The S&P 500 Index, an unmanaged index, measures the performance of 500 widely held, large-capitalization U.S. stocks and is frequently used as a general measure of market performance.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Understanding Your Fund's Expenses

(Unaudited)

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.

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.

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.

Portfolio of Investments (continued)

August 31, 2013 (Unaudited)

Fair Value Measurements (continued)

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Fair Value Measurements (continued)

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

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Marsico Focused Equities Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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

The Trust may issue an unlimited number of shares (without par value). The Fund offers Class A, Class B, Class C, Class I, Class R4 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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.

Columbia Marsico Focused Equities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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

Semiannual Report 2013
21



Columbia Marsico Focused Equities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadviser (see Subadvisory Agreement below) has the primary responsibility for the day-to-day portfolio management of the Fund. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.66% 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 investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.06% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $3,079.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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

Columbia Marsico Focused Equities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 fees. Class I shares do not pay transfer agent fees.

For the six months ended August 31, 2013, the Fund's annualized 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

   

0.21

   

Class R4

   

0.21

   

Class Z

   

0.20

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $3,952.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 $125,395 for Class A, $2,009 for Class B and $3,139 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

Columbia Marsico Focused Equities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $825,040,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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. The Fund has elected to treat late year ordinary losses of $2,234,270 at February 28, 2013 as arising on March 1, 2013.

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 $767,891,976 and $1,413,925,796, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 34.3% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such account. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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.

Consumer Discretionary Risk

The Fund's portfolio managers may invest significantly in issuers operating in the consumer discretionary sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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

Semiannual Report 2013
24



Columbia Marsico Focused Equities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia Marsico Focused Equities Fund

Approval of Investment Management Services and Subadvisory Agreements

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Marsico Focused Equities Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Marsico Capital Management, LLC (the Subadviser), the Subadviser has provided portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

Columbia Marsico Focused Equities Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser, which is unaffiliated with the Investment Manager, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality, subject to Columbia Management's ongoing heightened scrutiny of the Subadviser's organization and performance.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed the Fund's underperformance for certain periods, noting that appropriate steps (such as changes to management teams) had been taken or are contemplated to help improve the Fund's performance.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for selecting and monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board took into account management's view that the Fund's relative underperformance reflected the interrelationship of market conditions with the particular investment strategies employed by the Marsico team. The Board observed that the Subadviser was subject to Columbia Management's ongoing heightened scrutiny of its performance.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including,

Columbia Marsico Focused Equities Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

Not FDIC insured • No bank guarantee • May lose value



President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The Russell Midcap Value Index, an unmanaged index, measures the performance of those Russell Midcap Index companies with lower price-to-book ratios and forecasted growth values.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Mid Cap Value Fund

Understanding Your Fund's Expenses

(Unaudited)

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 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 investment vehicles (including mutual funds and exchange-traded funds).

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Mid Cap Value Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Mid 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 K, Class R, Class R4, Class R5, Class W, Class Y and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class K shares are not subject to sales charges, however this share class is closed to new investors.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class W shares are not subject to sales charges and are available only 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 generally available only to certain retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask prices on such exchanges or markets. Foreign currency exchange rates are

Semiannual Report 2013
27



Columbia Mid Cap Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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.

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

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

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 investment management fee is an annual fee that is equal to a percentage of the Fund's average daily net assets that declines from 0.76% to 0.62% as the Fund's net assets increase. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.66% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 annualized effective administration fee rate for the six months ended August 31, 2013 was 0.05% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $6,288.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class K and Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to each share class.

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

Beginning November 1, 2012, Class Y shares are not subject to transfer agent fees for at least twelve months.

For the six months ended August 31, 2013, the Fund's annualized 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

0.20

   

Class R5

   

0.05

   

Class W

   

0.19

   

Class Z

   

0.19

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $10,250.

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 K shares for the provision of various administrative, recordkeeping, communication and educational services.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 of the Fund.

The Fund may pay a distribution fee 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 $118,883 for Class A, $2,617 for Class B and $728 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

This agreement may be modified or amended only with approval from all parties.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $2,866,045,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, 2 unaffiliated shareholder accounts owned an aggregate of 36.6% 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.

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A.

whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. Significant Risks

Financial Sector Risk

The Fund's portfolio managers may invest significantly in issuers operating in the financial sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

August 31, 2013 (Unaudited)

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.

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.

Columbia Mid Cap Value Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Mid Cap Value Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013

Columbia Mid Cap Value Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, 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. Please visit columbiamanagement.com/mutual-funds/appended-performance for more information.

MSCI Europe, Australasia and the Far East (EAFE) Value Index (Net) is a subset of the MSCI EAFE Index (Net), and constituents of the index include securities from Europe, Australasia and the Far East. The index generally represents approximately 50% of the free float-adjusted market capitalization of the underlying MSCI EAFE Index (Net), and consists of those securities classified by MSCI Inc. as most representing the value style, such as higher book value-to-price ratios, higher forward earnings-to-price ratios, higher dividend yields and lower forecasted growth rates than securities representing the growth style.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Overseas Value Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

Semiannual Report 2013

Columbia Overseas Value Fund

Portfolio of Investments (continued)

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 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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific  or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Forward foreign currency exchange contracts are valued at unrealized appreciation (depreciation).

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Notes to Financial Highlights

(a)  Shares commenced operations on February 28, 2013.

(b)  Calculation of the net gain (loss) per share (both realized and unrealized) does not correlate to the aggregate realized and unrealized gain (loss) presented in the Statement of Operations due to the timing of sales and repurchases of Fund shares in relation to fluctuations in the market value of the portfolio.

(c)  In addition to the fees and expenses which the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of the acquired funds in which it invests. Such indirect expenses are not included in the reported expense ratios.

(d)  Annualized.

(e)  Total net expenses include the impact of certain waivers/reimbursements made by the Investment Manager and certain of its affiliates, if applicable.

(f)  The benefits derived from expense reductions had an impact of less than 0.01%.

Columbia Overseas Value Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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 A, Class B, Class C, Class I, Class K, Class W and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class K shares are not subject to sales charges, however this share class is closed to new investors.

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

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, to

Semiannual Report 2013
24



Columbia Overseas Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 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.

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.

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 fair value.

Foreign Currency Transactions and Translations

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 (making it difficult for the Fund to sell, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Fund's risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives, there is minimal counterparty credit risk to the Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is an agreement between a Fund and a counterparty that governs OTC

Semiannual Report 2013
25



Columbia Overseas Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

derivatives and forward foreign currency exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage over a specified time period or the Fund fails to meet the terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Fund would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are OTC agreements between two parties to buy and sell a currency at a set price on a future date. These contracts are typically 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 and to shift investment exposure from one currency to another. These instruments may be used for other purposes in future periods.

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 expires or 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.

Options Contracts

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. Option contracts can be either exchange traded or OTC. The Fund purchased and wrote option contracts to decrease the Fund's exposure to equity risk and to increase return on investments, to facilitate buying and selling of securities for investments and to implement a particular view on individual stocks that were more efficiently accomplished via options than the underlying equities. These instruments may be used for other purposes in future periods. 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.

Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of

Semiannual Report 2013
26



Columbia Overseas Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

the option written. The Fund will realize a gain or loss when the option contract is closed or expires. When 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.

For OTC options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. 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 above the strike price. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price 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. Option contracts written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. 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.

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 generally 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.

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 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.

Semiannual Report 2013
28



Columbia Overseas Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid annually. Net realized capital gains, if any, are distributed along with the income distribution. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.79% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.08% to 0.05% as the Fund's net assets increase. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.08% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $1,097.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class K shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class K shares.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.47

%

 

Class B

   

0.47

   

Class C

   

0.47

   

Class K

   

0.05

   

Class W

   

0.42

   

Class Z

   

0.42

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $20.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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% and 0.25% of the

average daily net assets attributable to Class B, Class C and Class W shares of the Fund.

The Fund may pay a distribution fee 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 $43,545 for Class A, $1,495 for Class B and $129 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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 as well as any reorganization costs allocated to the Fund) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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. Reorganization (see Note 9) costs were allocated to the Fund only to the extent they are expected to be offset by the anticipated reduction in expenses borne by the Fund's shareholders during the first year following the reorganization.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $220,106,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation

 

$

21,754,000

   

Unrealized depreciation

   

(8,140,000

)

 

Net unrealized appreciation

 

$

13,614,000

   

The following capital loss carryforward, determined as of February 28, 2013 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 ($)

2,526,529

   

Unlimited long-term

   

546,941

   

Total

   

5,467,286

   

Unlimited capital loss carryforwards are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date may be more likely to expire unused.

Under current tax rules, regulated investment companies can elect to treat post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. The Fund has elected to treat post-October capital losses of $225,295 at February 28, 2013 as arising on March 1, 2013.

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 $78,058,525 and $97,521,469, respectively, for the six months ended August 31, 2013.

Transactions to realign the Fund's portfolio following the merger as described in Note 9 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 $8,899,041and $9,001,280, respectively.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, one unaffiliated shareholder account owned 19.1% 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 11.1% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) the one-month LIBOR rate plus 1.00%. Each borrowing under the credit facility

Semiannual Report 2013
31



Columbia Overseas Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. Fund Merger

At the close of business on March 15, 2013, the Fund acquired the assets and assumed the identified liabilities of Columbia Multi-Advisor International Value Fund, a series of Columbia Funds Series Trust II (the acquired fund). The reorganization was completed after shareholders of the acquired fund approved a plan of reorganization on February 27, 2013. 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 $30,016,215 and the combined net assets immediately after the acquisition were $257,671,466.

The merger was accomplished by a tax-free exchange of 40,021,347 shares of the acquired fund valued at $227,655,251 (including $12,260,969 of unrealized appreciation).

In exchange for the acquired fund's shares, the Fund issued the following number of shares:

   

Shares

 

Class A

   

26,646,303

   

Class B

   

1,692,156

   

Class C

   

578,148

   

Class I

   

1,031

   

Class K

   

25,842

   

Class Z

   

8,336

   

For financial reporting purposes, net assets received and shares issued by the Fund were recorded at fair value; however, the acquired 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 the acquired 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, 2013, 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 six months ended August 31, 2013 would have been approximately $4.1 million, $12.2 million, $(10.1) million and $6.1 million, respectively.

Note 10. 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 11. 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 12. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Overseas Value Fund

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Overseas Value Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Semiannual Report 2013
34



Columbia Overseas Value Fund

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Columbia Small Cap Value Fund II

Not FDIC insured • No bank guarantee • May lose value



President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The Russell 2000 Value Index, an unmanaged index, tracks the performance of those Russell 2000 Index companies with lower price-to-book ratios and lower forecasted growth values.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Small Cap Value Fund II

Understanding Your Fund's Expenses

(Unaudited)

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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

Portfolio of Investments (continued)

Fair Value Measurements (continued)

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Small Cap Value Fund II

Notes to Financial Statements

August 31, 2013 (Unaudited)

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

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 R4, Class R5, Class Y and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class Y shares are not subject to sales charges and are generally available only to certain retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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

Semiannual Report 2013
25



Columbia Small Cap Value Fund II

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

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 generally 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.

The Fund may receive distributions from holdings in business development companies (BDCs), exchange traded funds (ETFs) and real estate investment trusts (REITs), which report information on the character of their distributions annually. These 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. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. Management's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the BDCs, ETFs and REITs, which could result in a proportionate change 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 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 at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 investment 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 0.70% as the Fund's net assets increase. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.74% of the Fund's average daily net assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.08% to 0.05% as the Fund's net assets increase. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.07% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $2,995.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares. Beginning November 8, 2012, Class Y shares are not subject to transfer agent fees for at least twelve months.

For the six months ended August 31, 2013, the Fund's annualized 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 R

   

0.19

   

Class R4

   

0.20

   

Class R5

   

0.05

   

Class Z

   

0.19

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $120.

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

Semiannual Report 2013

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rates of 0.75%, 0.75% and 0.50% of the average daily net assets attributable to 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 Fund shares were $1,629 for Class A and $91 for Class B shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the period disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $1,209,060,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation

 

$

439,355,000

   

Unrealized depreciation

   

(39,447,000

)

 

Net unrealized appreciation

 

$

399,908,000

   

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 $317,342,197 and $364,211,773, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, three unaffiliated shareholder accounts owned an aggregate of 52.1% of the outstanding shares of the Fund. The Fund has no knowledge about whether any portion of those shares was owned beneficially by such accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund

Note 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. Significant Risks

Financial Sector Risk

The Fund's portfolio managers may invest significantly in issuers operating in the financial sector. The Fund may be more susceptible to the particular risks of this sector than if the Fund were invested in a wider variety of issuers operating in unrelated sectors.

Note 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Small Cap Value Fund II

Approval of Investment Management Services Agreement

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Small Cap Value Fund II (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Trustees analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Trustees specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Independent Trustees noted the information they received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Independent Trustees took into account their comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Independent Trustees also recalled the information the CIO provided them identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Independent Trustees also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services (such as strong accounting performance measures, refined derivatives processing and enhancements to the electronic communications under the affiliated and unaffiliated service provider oversight program). In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Independent Trustees also took into account the organization and strength of the Fund's and its service providers' compliance programs. In

Columbia Small Cap Value Fund II

Approval of Investment Management Services Agreement (continued)

addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement and the Fund's other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance was appropriate in light of the particular management style involved and the particular market environment.

Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Based on its review, the Board concluded that the Fund's investment management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Independent Trustees took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement.

Columbia Marsico Global Fund

Not FDIC insured • No bank guarantee • May lose value



President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Columbia Marsico Global Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

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.

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.

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

Fair Value Measurements (continued)

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Columbia Marsico Global Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

Note 1. Organization

Columbia Marsico Global 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 C, Class R and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 C shares are subject to a 1.00% CDSC on shares redeemed within one year of purchase.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 open-end investment companies, including money market funds, are valued at net asset value.

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.

Semiannual Report 2013
18



Columbia Marsico Global Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadviser (see Subadvisory Agreement below) has the primary responsibility for the day-to-day portfolio management of the Fund. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.79% 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 investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.08% to 0.05% as the Fund's net assets increase. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.08% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $832.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.14

%

 

Class C

   

0.14

   

Class R

   

0.14

   

Class Z

   

0.14

   

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, no minimum account balance fees were charged by the Fund.

Semiannual Report 2013

Columbia Marsico Global Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rate of 0.75% and 0.50%, respectively, 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 $16,932 for Class A shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $26,696,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

Unrealized appreciation

(189,000

)

 

Net unrealized appreciation

 

$

3,324,000

   

The following capital loss carryforward, determined as of February 28, 2013 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:

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. The Fund has elected to treat late year ordinary losses of $32,917 at February 28, 2013 as arising on March 1, 2013.

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

The cost of purchases and proceeds from sales of securities, excluding short-term obligations, aggregated to $19,666,125 and $11,448,142, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, two unaffiliated shareholder accounts owned an aggregate of 32.5% 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. Affiliated shareholder accounts owned 44.5% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Fund had no borrowings during the six months ended August 31, 2013.

Note 9. 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 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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

Notes to Financial Statements (continued)

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.

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.

Columbia Marsico Global Fund

Approval of Investment Management Services and Subadvisory Agreements

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Marsico Global Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Marsico Capital Management, LLC (the Subadviser), the Subadviser has provided portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

Columbia Marsico Global Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser, which is unaffiliated with the Investment Manager, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality, subject to Columbia Management's ongoing heightened scrutiny of the Subadviser's organization and performance.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance met expectations.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for selecting and monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board observed that the Subadviser was subject to Columbia Management's ongoing heightened scrutiny of its performance.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or

25



Columbia Marsico Global Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe's median expense ratio. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

President's Message

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The MSCI EAFE Index (Net) is a free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the US & Canada. The index is compiled from a composite of securities markets of Europe, Australasia and the Far East and is widely recognized by investors in foreign markets as the measurement index for portfolios of non-North American securities.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes (except the MSCI EAFE Index (Net), which reflects reinvested dividends net of withholding taxes) or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia Marsico International Opportunities Fund

Understanding Your Fund's Expenses

(Unaudited)

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.

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.

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.

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

Columbia Marsico International Opportunities Fund

Portfolio of Investments (continued)

August 31, 2013 (Unaudited)

Fair Value Measurements (continued)

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.

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 may 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.

Under the direction of the Fund's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third- party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia Marsico International Opportunities Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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, Class R4 and Class Z shares. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by law. Different share classes pay different distribution amounts to the extent the expenses of such share classes differ, and distributions in liquidation will be proportional to the net asset value of each share class. 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors. Class R4 shares commenced operations on November 8, 2012.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, to determine a good faith estimate that reasonably reflects the

Semiannual Report 2013
22



Columbia Marsico International Opportunities Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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 fair value.

Foreign Currency Transactions and Translations

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.

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 generally 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.

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 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 realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to Shareholders

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

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 Fund's subadviser (see Subadvisory Agreement below) has the primary responsibility for the day-to-day portfolio management of the Fund. The investment 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. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.79% 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 investment of the Fund's assets.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also 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 0.08% to 0.05% as the Fund's net assets increase. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.08% of the Fund's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to a company providing limited administrative services to the Fund and the Board. That company's expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the

six months ended August 31, 2013, other expenses paid to this company were $1,281.

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.

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 also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees.

For the six months ended August 31, 2013, the Fund's annualized effective transfer agent fee rates as a percentage of average daily net assets of each class were as follows:

Class A

   

0.19

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class' 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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $740.

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.

Under the Plans, the Fund pays 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. Also under the Plans, the Fund pays 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 rates of 0.75%, 0.75% and 0.50% of the average daily net assets attributable to 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 Fund shares were $5,740 for Class A, $1,309 for Class B and $104 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

This agreement may be modified or amended only with approval from all parties.

Note 4. 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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $182,869,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

August 31, 2013 (Unaudited)

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 $209,509,468 and $369,822,873, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

The Fund invests 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 — affiliated issuers" 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 7. Shareholder Concentration

At August 31, 2013, two unaffiliated shareholder accounts owned an aggregate of 45.6% 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 8. Line of Credit

The Fund has entered into a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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.

The commitment fee is included in other expenses in the Statement of Operations.

For the six months ended August 31, 2013, the average daily loan balance outstanding on days when borrowing existed was $4,690,625 at a weighted average interest rate of 1.19%. Interest expense incurred by the Fund is recorded as interest expense in the Statement of Operations.

Note 9. 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 10. 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 11. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Columbia Marsico International Opportunities Fund

Approval of Investment Management Services and Subadvisory Agreements

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Marsico International Opportunities Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Marsico Capital Management, LLC (the Subadviser), the Subadviser has provided portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

Columbia Marsico International Opportunities Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Services Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the Subadvisory Agreement. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the performance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board approve renewal of the Subadvisory Agreement with the Subadviser, which is unaffiliated with the Investment Manager, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality, subject to Columbia Management's ongoing heightened scrutiny of the Subadviser's organization and performance.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the Subadviser was in a position to continue to provide a high quality and level of services to the Fund.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance was appropriate in light of the particular management style involved and the particular market environment.

Additionally, the Board reviewed the performance of the Subadviser and Columbia Management's process for selecting and monitoring the Subadviser. The Board considered, in particular, management's rationale for recommending the continued retention of the Subadviser. The Board took into account management's view that the Fund's relative underperformance reflected the interrelationship of market conditions with the particular investment strategies employed by the Marsico team. The Board observed that the Subadviser was subject to Columbia Management's ongoing heightened scrutiny of its performance.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including,

Semiannual Report 2013
29



Columbia Marsico International Opportunities Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that: (i) the Funds' standardized investment management fee rates, particularly in the context of the current competitive fee landscape, were within a reasonable range; and (ii) the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's investment management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the Advisory Agreements.

Dear Shareholders,

A return to volatility

Volatility returned to the financial markets in the second quarter of 2013, as uncertainty about the global economy, monetary policy and the impact of the sequester's spending cuts weighed on investors. Households advanced their spending but also allocated less to savings. Labor markets continued to crank out jobs at a steady pace, slowly reducing unemployment. Housing activity remained strong and retail sales were higher despite no real increase in income. The single weak spot was in the manufacturing sector, where activity slowed. While the consumer has weathered the domestic drag well, business has been closer to the global slowdown and effects of sequestration. Businesses remain very cautious, keeping inventories and staffs lean, and are planning for but not yet confident enough to make capital expenditures.

Against this backdrop, equities outperformed fixed income during the second quarter of 2013. Small-cap stocks outperformed large- and mid-cap stocks, and growth outperformed value except for in the large-cap sector. Outside the United States, foreign stock markets generally lost ground, with the most significant losses sustained by emerging markets.

Columbia Management to begin delivering summary prospectuses

Each Columbia fund is required to update its prospectus on an annual basis. Beginning with June 2013 prospectus updates, shareholders of Columbia retail mutual funds will start to receive a summary prospectus, rather than the full length (statutory) mutual fund prospectus they have received in the past.

Each fund's summary prospectus will include the following key information:

>  Investment objective

>  Fee and expense table

>  Portfolio turnover rate information

>  Principal investment strategies, principal risks and performance information

>  Management information

>  Purchase and sale information

>  Tax information

>  Financial intermediary compensation information

Each fund's statutory prospectus will contain additional information about the fund and its risks. Both the statutory and summary prospectus will be updated each year, and will be available at columbiamanagement.com. Shareholders may request a printed version of a statutory prospectus at no cost by calling 800.345.6611 or sending an email to serviceinquiries@columbiamanagement.com.

Returns for Class A are shown with and without the maximum initial sales charge of 5.75%. Returns for Class B are shown with and without the applicable contingent deferred sales charge (CDSC) of 5.00% in the first year, declining to 1.00% in the sixth year and eliminated thereafter. Returns for Class C are shown with and without the 1.00% CDSC for the first year only. The Fund's other classes are not subject to sales charges and have limited eligibility. Please see the Fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of 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.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiamanagement.com or calling 800.345.6611.

*The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund's oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. 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.

The MSCI EAFE (Europe, Australasia, Far East) Value Index (Net) is a subset of the MSCI EAFE Index (Net), and constituents of the index include securities from Europe, Australasia and the Far East. The index generally represents approximately 50% of the free float-adjusted market capitalization of the MSCI EAFE Index (Net), and consists of those securities classified by MSCI Inc. as most representing the value style, such as, higher book value-to-price ratios, higher forward earnings-to-price ratios, higher dividend yields and lower forecasted growth rates than securities representing the growth style.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

Columbia International Value Fund

Understanding Your Fund's Expenses

(Unaudited)

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 365.

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 investment 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.

Financial Highlights

The following tables are intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. The per share amounts and percentages reflect income and expenses assuming inclusion of the Fund's proportionate share of the income and expenses of Columbia International Value Master Portfolio. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any, and is not annualized for periods of less than one year.

Columbia International Value Fund

Notes to Financial Statements

August 31, 2013 (Unaudited)

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 interest in the net assets of the Master Portfolio, which is equal to 98.6% at August 31, 2013. 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, Class R4, Class R5 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 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 available only to the Columbia Family of Funds.

Class R shares are not subject to sales charges and are generally available only to certain retirement plans and other eligible investors.

Class R4 shares are not subject to sales charges and are generally available only to omnibus retirement plans and certain other eligible investors.

Class R5 shares are not subject to sales charges and are generally available only to investors purchasing through authorized investment professionals and omnibus retirement plans.

Class Z shares are not subject to sales charges and are available only to certain eligible investors, which are subject to different investment minimums.

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 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, an open-end management investment company having the same investment objectives as the Feeder Fund. 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

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

Semiannual Report 2013
20



Columbia International Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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

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.

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 (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 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

Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. 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 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.

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 Feeder Fund indirectly pays for investment management and subadvisory services and a portion of the administrative services through its investment in the Master Portfolio (see Notes to Financial Statements of the Master Portfolio).

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Fund Administrator. Effective June 1, 2013, the Feeder Fund pays the Fund Administrator an annual fee for administration and accounting services equal to

Semiannual Report 2013
21



Columbia International Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

0.02% of the Fund's average daily net assets. Prior to June 1, 2013, the administration fee was equal to 0.17% of the Fund's average daily net assets. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.12% of the Fund's average daily net assets.

Other Expenses

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 six months ended August 31, 2013, other expenses paid to this company were $347.

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.

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.

The Transfer Agent receives monthly account-based service fees based on the number of open accounts and also receives sub-transfer agency fees based on a percentage of the average aggregate value of the Feeder Fund's shares maintained in omnibus accounts (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 fees. Class I shares do not pay transfer agent fees. Total transfer agent fees for Class R5 shares are subject to an annual limitation of not more than 0.05% of the average daily net assets attributable to Class R5 shares.

For the six months ended August 31, 2013, the Feeder Fund's annualized 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 R

   

0.19

   

Class R4

   

0.18

   

Class R5

   

0.05

   

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 six months ended August 31, 2013, these minimum account balance fees reduced total expenses by $920.

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.

Under the Plans, the Feeder Fund pays 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 Feeder Fund. Also under the Plans, the Feeder Fund pays 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 Feeder Fund and the payment of a monthly distribution fee at the maximum annual rate of 0.75%, 0.75% and 0.50% of the average daily net assets attributable to Class B, Class C and Class R shares of the Feeder Fund, respectively.

Sales Charges

Sales charges, including front-end charges and CDSCs, received by the Distributor for distributing Feeder Fund shares were $27,509 for Class A, $312 for Class B and $462 for Class C shares for the six months ended August 31, 2013.

Expenses Waived/Reimbursed by the Investment Manager and its Affiliates

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) for the periods disclosed below, 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:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, 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

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.

The following capital loss carryforward, determined as of February 28, 2013 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 ($)

Unlimited long-term

     

171,398,112

   
 

Total

Unlimited capital loss carryforwards are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date 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. The Feeder Fund has elected to treat late year ordinary losses of $2,206,883 and post-October capital losses of $98,895,321 at February 28, 2013 as arising on March 01, 2013.

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. Shareholder Concentration

At August 31, 2013, three unaffiliated shareholder accounts owned 36.7% of the outstanding shares of the Feeder Fund. The Feeder Fund has no knowledge about whether any portion of those shares was owned beneficially.

Note 6. 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,

Semiannual Report 2013
23



Columbia International Value Fund

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 7. 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 8. Information Regarding Pending and Settled Legal Proceedings

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.

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.

Portfolio of Investments (continued)

August 31, 2013 (Unaudited)

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 Master Portfolio 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 Master Portfolio'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 Master Portfolio 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 Master Portfolio'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 Master Portfolio 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.

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.

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 may 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.

Under the direction of the Master Portfolio's Board of Trustees (the Board), the Investment Manager's Valuation Committee (the Committee) is responsible for carrying out the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third-party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

The Master Portfolio'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.

There were no transfers of financial assets between Levels 1 and 2 during the period.

Forward foreign currency exchange contracts are valued at unrealized appreciation (depreciation).

Columbia International Value Master Portfolio

Notes to Financial Statements

August 31, 2013 (Unaudited)

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. Information presented in these financial statements pertains to Columbia International Value Master Portfolio (the Master Portfolio).

The following investors were invested in the Master Portfolio at August 31, 2013:

Columbia International Value Fund (the Feeder Fund)

   

98.6

%

 
Columbia Management Private Funds VII, LLC —
International Value Fund
   

1.4

%

 

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 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 Master Portfolio 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 ask prices on such exchanges or markets.

Foreign equity 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 ask 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 or market, 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 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.

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.

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 fair 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

Semiannual Report 2013
36



Columbia International Value Master Portfolio

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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 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.

Derivative Instruments

The Master Portfolio 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 Master Portfolio 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 Master Portfolio to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts and market values of derivative instruments, if any, are not recorded in the financial statements.

The Master Portfolio and any counterparty are required to maintain an agreement that requires the Master Portfolio and that counterparty to monitor (on a daily basis) the net fair value of all derivatives entered into pursuant to the agreement between the Master Portfolio and such counterparty. If the net fair value of such derivatives between the Master Portfolio and that counterparty exceeds a certain threshold (as defined in the agreement), the Master Portfolio 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 Master Portfolio or any counterparty. The notional amounts of

derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. A Master Portfolio's risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Master Portfolio and the amount of any initial margin held by the counterparty. With exchange traded or centrally cleared derivatives , there is minimal counterparty credit risk to the Master Portfolio since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker's customers, potentially resulting in losses to the Master Portfolio.

In order to better define its contractual rights and to secure rights that will help the Master Portfolio mitigate its counterparty risk, the Master Portfolio may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Master Portfolio and a counterparty that governs OTC derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Master Portfolio may, under certain circumstances, offset with the counterparty certain derivative financial instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Columbia International Value Master Portfolio

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange or clearinghouse for exchange traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives. For OTC derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Master Portfolio and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g. $500,000) before a transfer has to be made. To the extent amounts due to the Master Portfolio from its counterparties are not fully collateralized, contractually or otherwise, the Master Portfolio bears the risk of loss from counterparty nonperformance. The Master Portfolio attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Master Portfolio's net assets decline by a stated percentage over a specified time period or the Master Portfolio fails to meet the terms of the ISDA Master Agreement, which would cause the Master Portfolio to accelerate payment of any net liability owed to the counterparty. The Master Portfolio also has termination rights if the counterparty fails to meet the terms of the ISDA Master Agreement. In addition to considering counterparty credit risk, the Master Portfolio would consider terminating the derivative contracts based on whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Master Portfolio does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are OTC 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 Master Portfolio utilized forward foreign currency exchange contracts [to hedge the currency exposure associated with some or all of the Master Portfolio'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]. These instruments may be used for other purposes in future periods.

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

The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Master Portfolio'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.

Options Contracts

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. Option contracts can be either exchange traded or OTC. The Master Portfolio purchased and wrote option contracts to produce incremental earnings and protect gains/decrease the Master Portfolio's exposure to equity risk and to increase return on investments, protect gains, and facilitate buying and selling of securities for investments. These instruments may be used for other purposes in future periods. 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 Master Portfolio to secure certain OTC option contract trades. Cash collateral held or posted by the Master Portfolio for such option contract trades must be returned to the counterparty or the Master Portfolio upon closure, exercise or expiration of the contract.

Options contracts purchased are recorded as investments. When the Master Portfolio writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. The Master Portfolio will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased

Columbia International Value Master Portfolio

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

For OTC options purchased, the Master Portfolio bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Master Portfolio should the counterparty fail to perform under the contracts. The Master Portfolio 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 Master Portfolio 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 Master Portfolio may incur a loss if the market price of the security decreases and the option contract is exercised. The Master Portfolio's maximum payout in the case of written put option contracts represents the maximum potential amount of future payments (undiscounted) that the Master Portfolio could be required to make under the contract. For OTC options contracts, the transaction is also subject to counterparty credit risk. Option contracts written by the Master Portfolio do not typically give rise to counterparty credit risk, as options written generally obligate the Master Portfolio and not the counterparty to perform. 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.

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 generally 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.

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

Semiannual Report 2013
40



Columbia International Value Master Portfolio

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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 June 1, 2013, the investment management fee is an annual fee that is equal to a percentage of the Master Portfolio's average daily net assets that declines from 0.79% to 0.62% as the Master Portfolio's net assets increase. Prior to June 1, 2013, the investment management fee was equal to a percentage of the Master Portfolio's average daily net assets that declined from 0.85% to 0.66% as the Master Portfolio's net assets increased. The annualized effective investment management fee rate for the six months ended August 31, 2013 was 0.82% of the Master Portfolio's average daily net assets.

Subadvisory Agreement

Prior to June 1, 2013, Brandes Investment Partners, L.P. (Brandes) served as the subadviser of the Master Portfolio. The Investment Manager compensated Brandes to manage the investment of the Master Portfolio's assets. Effective June 1, 2013, the Investment Manager assumed the day-to-day management responsibilities of the Master Portfolio from Brandes.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Master Portfolio Administrator. Effective June 1, 2013, the Master Portfolio pays the Master Portfolio Administrator an annual fee for administration and accounting services equal to a percentage of the Master Portfolio's average daily net assets that declines from 0.06% to 0.03% as the Master Portfolio's net assets increase. Prior to June 1, 2013, the administration fee was equal to 0.05% of the Master Portfolio's average daily net assets. The annualized effective administration fee rate for the six months ended August 31, 2013 was 0.05% of the Master Portfolio's average daily net assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Master Portfolio or the Board, including payments to a company providing limited administrative services to the Master Portfolio and the Board. That company's expense include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended August 31, 2013, other expenses paid to this company were $1,388.

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.

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

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.

At August 31, 2013, the cost of investments for federal income tax purposes was approximately $326,046,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:

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 $387,461,925 and $799,463,442, respectively, for the six months ended August 31, 2013.

Note 6. Affiliated Money Market Fund

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 7. 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. whereby the Master Portfolio may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. 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. 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 (ii) 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. The commitment fee is included in other expenses in the Statement of Operations.

The Master Portfolio had no borrowings during the six months ended August 31, 2013.

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 9. 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 10. Information Regarding Pending and Settled Legal Proceedings

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

Columbia International Value Master Portfolio

Notes to Financial Statements (continued)

August 31, 2013 (Unaudited)

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.

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.

Columbia International Value Fund

Approval of Investment Management Services and Subadvisory Agreements

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia International Value Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between Columbia Management and Brandes Investment Partners, L.P. (the Subadviser), the Subadviser has provided portfolio management and related services for Columbia International Value Master Portfolio, in which the Fund invests all or substantially all of its assets.

On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the IMS Agreement and the Subadvisory Agreement (together, the Advisory Agreements). Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2013, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Trustees (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March and April were first supplied in draft form to designated representatives of the Independent Trustees, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials (including proposed additional breakpoints in IMS fees for certain Funds) were revised to reflect discussion and subsequent requests made by the Contracts Committee. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. Further, the Board retained an independent consulting firm, Bobroff Consulting (the Independent Consultant), to assist the Independent Trustees in their review of IMS fees, expense caps and Ameriprise Financial's profitability. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.

The Board, at its April 15-17, 2013 in-person Board meeting (the April Meeting), considered the renewal of the Advisory Agreements for an additional one-year term. At the April Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory and subadvisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement and the termination of the Subadvisory Agreement (effective following the conclusion of a short-term renewal period to cover the termination notice period required under the Subadvisory Agreement).

Nature, Extent and Quality of Services Provided by Columbia Management and the Subadviser

The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management and the Subadviser, as well as their history, reputation, expertise, resources and relative capabilities, and the qualifications of their personnel.

With respect to Columbia Management, the Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the recent globalization initiative, which fosters increased worldwide investment support of global products, continued investment in upgrading technology (such as the implementation of new systems and hardware), the hiring of a Chief Interest Rate Strategist as part of Columbia Management's fixed income team and the addition of Columbia Management investment personnel to the Asset Allocation, Quantitative and Technology teams. The Board took into account the information it received and reviewed concerning Columbia Management's ongoing oversight and monitoring of the subadvisers, observing the broad scope of services provided by Columbia Management to each subadvised Fund, including, among other noted services, investment, risk and compliance oversight. The Board also took into account the Subadviser oversight structure and the Columbia Management team dedicated thereto. The Board also noted the information it received concerning Columbia Management's ability to retain its key portfolio management personnel. In this regard, the Board took into account its comprehensive discussions with Columbia Management's Chief Investment Officer (the CIO), observing the organizational depth of Columbia Management and the capabilities of its investment personnel. The Board also recalled the information the CIO provided it identifying the strengths and areas for enhancement of each Columbia Management investment team, as well as the

Columbia International Value Fund

Approval of Investment Management Services and Subadvisory Agreements (continued)

discussion with the CIO regarding the investment personnel talent being infused to enhance support for certain Funds. The Board also observed the materials demonstrating the strength and depth of Columbia Management's equity and fixed income research departments.

In connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting significant achievements in 2012 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund's Administrative Service Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of Columbia Management and its affiliates and their ability to carry out their responsibilities under the IMS Agreement and the Fund's other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. In addition, the Board discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund.

With respect to the Subadviser, the Board observed that it had previously approved the Subadviser's code of ethics and compliance program, that the Chief Compliance Officer of the Fund continues to monitor the code and the program, and that no material concerns have been reported. The Board also considered the Subadviser's organizational strength and resources (including recent organizational changes), portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser's capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadviser agreements for subadvisers who manage other funds managed by the Investment Manager. In the context of the review of the foregoing, the Board recalled its multiple meetings with Brandes (and Columbia Management regarding Brandes) within the preceding six months, noting concerns raised with the wherewithal of Brandes' organization and its continued underperformance for a number of periods. The Board also considered Columbia Management's recommendation at the March 2013 Contracts Committee meeting that Brandes be replaced with Columbia Management's Overseas Value Team. The Board noted that it had been provided with materials discussing the depth, experience and capabilities of the Overseas Value Team, and the related proposed investment strategy change for the Fund. Based on the foregoing, and based on other information received (both oral and written) and other considerations, including, in particular, the underperformance of the Fund (discussed below) as well as the Investment Manager's recommendation that the Board terminate the Subadvisory Agreement with the Subadviser, which is unaffiliated with the Investment Manager, at the expiration of the termination notice period under the Subadvisory Agreement, the Board concluded that the services being performed under the Subadvisory Agreement were of an acceptable quality for purposes of renewing the contract for only a short-term period until the expiration of the termination notice period.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the Advisory Agreements, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance had not met expectations for certain periods. The Board observed that appropriate action (i.e., termination of the Subadviser) is contemplated to help improve the Fund's performance.

Additionally, the Board reviewed Columbia Management's process for monitoring the Subadviser and considered, in particular, management's rationale for recommending the termination of the Subadviser. The Board observed that the Subadviser's termination (and replacement by the Overseas Value Team) would be effective following the expiration of the termination notice period under the Subadvisory Agreement.

Approval of Investment Management Services and Subadvisory Agreements (continued)

Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management, its Affiliates and the Subadviser from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services to be provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to Columbia Management's profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by Columbia Management and discussed differences in how the products are managed and operated, noting no unreasonable differences in the levels of contractual fees.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). In this connection, the Board also considered the Independent Consultant's report that concluded that the Funds' expense cap philosophy of assuring that each Fund's total expense ratio is not above its peer universe median ratio is reasonable. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe's median expense ratio. Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board observed that the subadvisory fee level for the Subadviser was generally comparable to those charged by other subadvisers to similar funds managed by the Investment Manager. The Board also reviewed fee rates charged by the Subadviser to other client accounts. Based on its review, the Board concluded that the Fund's management and subadvisory fees were fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing, operating and distributing the Funds. In this regard, the Board observed that 2012 profitability approximates 2011 profitability and that, as was the case in 2011, 2012 profitability remained generally in line with (and, in many cases, lower than) the reported profitability of other asset management firms. Further, the Board considered the Independent Consultant's report that concluded that Columbia Management's profitability, particularly in comparison to industry competitors, was reasonable and not excessive. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

The Board also considered the economies of scale that might be realized by Columbia Management as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that IMS fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed.

Based on the foregoing, the Board, including all of the Independent Trustees, concluded that fees payable under the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 17, 2013, the Board, including all of the Independent Trustees, approved the renewal of the IMS Agreement, the renewal of the Subadvisory Agreement for a short-term period (until the effective date of the termination of the Subadvisory Agreement) and the termination of the Subadvisory Agreement.
