(a)	This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months of purchase, as follows: 1.00% if redeemed within 12 months of purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b)	This charge decreases over time.
(c)	This charge applies to redemptions within one year of purchase, with certain limited exceptions.
(d)	Other expenses for Class A, Class B, Class C, Class K, Class R, Class W and Class Z have been restated to reflect contractual changes to certain fees paid by the Fund.
(e)	Columbia Management Investment Advisers, LLC and certain of its affiliates have contractually agreed to waive fees and/or to reimburse expenses (excluding transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and extraordinary expenses) until February 28, 2015, unless sooner terminated at the sole discretion of the Fund’s Board of Trustees. Under this agreement, the Fund’s net operating expenses, subject to applicable exclusions, will not exceed the annual rates of 1.09% for Class A, 1.84% for Class B, 1.84% for Class C, 0.64% for Class I, 0.94% for Class K, 1.34% for Class R, 1.09% for Class W, 0.64% for Class Y and 0.84% for Class Z.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example illustrates the hypothetical expenses that you would incur over the time periods indicated, and assumes that:

■	you invest $10,000 in the applicable class of Fund shares for the periods indicated,
■	your investment has a 5% return each year, and
■	the Fund’s total annual operating expenses remain the same as shown in the Annual Fund Operating Expenses table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire as indicated in the preceding table, they are only reflected in the 1 year example and the first year of the other examples. Although your actual costs may be higher or lower, based on the assumptions listed above, your costs would be:

    

	1 year	3 years	5 years	10 years
Class A (whether or not shares are redeemed)	$581	$852	$1,143	$1,971
Class B (assuming redemption of all shares at the end of the period)	$687	$927	$1,292	$2,189
Class B (assuming no redemption of shares)	$187	$627	$1,092	$2,189
Class C (assuming redemption of all shares at the end of the period)	$287	$627	$1,092	$2,382
Class C (assuming no redemption of shares)	$187	$627	$1,092	$2,382
Class I (whether or not shares are redeemed)	$ 65	$235	$ 420	$ 953
Class K (whether or not shares are redeemed)	$ 96	$330	$ 582	$1,305
Class R (whether or not shares are redeemed)	$136	$473	$ 833	$1,848
Class W (whether or not shares are redeemed)	$111	$396	$ 701	$1,570
Class Y (whether or not shares are redeemed)	$ 65	$235	$ 420	$ 953
Class Z (whether or not shares are redeemed)	$ 86	$318	$ 568	$1,285

Portfolio Turnover

The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests primarily in debt obligations of U.S. and foreign issuers. Under normal market conditions, at least 80% of the Fund’s net assets (including the amount of any borrowings for investment purposes) will be invested in investment-grade corporate or government debt obligations, including money market instruments, of issuers located in at least three different countries. Although the Fund emphasizes high- and medium-quality debt securities, it may assume increased credit risk in seeking to achieve higher dividends and/or capital appreciation by investing in below investment-grade fixed-income securities (commonly referred to as “high yield securities” or “junk bonds”).

The Fund may invest in fixed income securities of any maturity and does not seek to maintain a particular dollar-weighted average maturity.

Under normal circumstances, the Fund generally invests at least 40% of its net assets in debt obligations of foreign governments, and companies that (a) maintain their principal place of business or conduct their principal business activities outside the U.S., (b) have their securities traded on non-U.S. exchanges or (c) have been formed under the laws of non-U.S. countries. This 40% minimum investment amount may be reduced to 30% if market conditions for these investments or specific foreign markets are deemed unfavorable. The Fund considers a company to conduct its principal business activities outside the U.S. if it derives at least 50% of its revenue from business outside the U.S. or had at least 50% of its assets outside the U.S.

In addition, in pursuing its objective, the Fund, relying on quantitative and qualitative analyses, may enter into various currency-, interest rate- and credit-related transactions involving derivatives instruments, including futures contracts (such as currency, bond, treasury, index and interest rate futures) and forward foreign currency contracts (forwards). The use of these derivatives instruments allows the Fund to obtain net long or net negative (short) exposure to selected currencies, interest rates and duration risks. The Fund may use these derivatives as well as “to be announced” (TBA) mortgage-backed securities in an effort to produce incremental earnings, for hedging purposes, to obtain increased or decreased exposures to various markets/sectors or to increase investment flexibility. Actual long and short exposures will vary over time based on factors such as market movements and assessments of market conditions.

In addition, under normal circumstances, the Fund uses forward foreign currency contracts in seeking to enhance returns based on fluctuations in the values of various foreign currencies relative to the U.S. dollar (the Currency Overlay Strategy). The Fund gains economic exposure to foreign currencies through its investment in forward foreign currency contracts comparable to the exposure that it would have had if it had bought or sold the foreign currencies directly.

The investment manager combines fundamental and quantitative analysis with risk management in identifying investment opportunities and constructing the Fund’s portfolio.

The Fund is non-diversified, which means that it can invest a greater percentage of its assets in the securities of fewer issuers than can a diversified fund.

Principal Risks

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective and you may lose money . The value of the Fund’s holdings may decline, and the Fund’s net asset value (NAV) and share price may go down.

Active Management Risk. Due to its active management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives. The Fund may fail to achieve its investment objective and you may lose money.

Changing Distribution Level Risk. The amount of the distributions paid by the Fund will vary and generally depends on the amount of interest income and/or dividends received by the Fund on the securities it holds. The Fund may not be able to pay distributions or may have to reduce its distribution level if the interest income and/or dividends the Fund receives from its investments decline.

Counterparty Risk. Counterparty risk is the risk that a counterparty to a financial instrument held by the Fund or by a special purpose or structured vehicle invested in by the Fund may become insolvent or otherwise fail to perform its obligations. As a result, the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Credit Risk. Credit risk is the risk that the issuer of a fixed-income security may or will default or otherwise become unable or unwilling, or is perceived to be unable or unwilling, to honor a financial obligation, such as making payments to the Fund when due. If the Fund purchases unrated securities, or if the rating of a security is lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual. Unrated securities held by the Fund may present increased credit risk as compared to higher-rated securities.

Derivatives Risk. Losses involving derivative instruments may be substantial, because a relatively small movement in the price of an underlying security, instrument, commodity, currency or index may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk and liquidity risk.

Derivatives Risk/Forward Contracts. A forward is a contract between two parties to buy or sell an asset at a specified future time at a price agreed today. Forwards are traded in the over-the-counter markets. The Fund may purchase forward contracts, including those on mortgage-backed securities in the “to be announced” (TBA) market. In the TBA market, the seller agrees to deliver the mortgage-backed securities for an agreed upon price on an agreed upon date, but makes no guarantee as to which or how many securities are to be delivered. Investments in forward contracts subject the Fund to leverage risk and counterparty risk.

Derivatives Risk/Forward Foreign Currency Contracts Risk. These instruments are a type of derivative contract whereby the Fund may agree to buy or sell a country’s or region’s currency at a specific price on a specific date in the future. These contracts may fall in value (sometimes dramatically) due to foreign market downswings or foreign currency value fluctuations. The Fund’s strategy of investing in these instruments may not be successful. Investment in these instruments also subjects the Fund to counterparty risk.

Derivatives Risk/Futures Contracts Risk. The loss that may be incurred in entering into futures contracts may exceed the amount of the premium paid and may be potentially unlimited. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s NAV. Additionally, as a result of the low collateral deposits normally involved in futures trading, a relatively small price movement in a futures contract may result in substantial losses to the Fund. Futures contracts may be illiquid. Furthermore, exchanges may limit fluctuations in futures contract prices during a trading session by imposing a maximum permissible price movement on each futures contract. The Fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement. Futures contracts executed on foreign exchanges may not provide the same protection as U.S. exchanges. These transactions involve additional risks, including counterparty risk, hedging risk and pricing risk.

Emerging Market Securities Risk. Securities issued by foreign governments or companies in emerging market countries are more likely to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, emerging market countries are more likely to experience instability resulting, for example, from rapid changes or developments in social, political and economic conditions. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity (i.e., lower trading volumes and less liquidity) than more developed countries. Emerging market securities tend to be more volatile than securities in more developed markets. Many emerging market countries are heavily dependent on international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and economic downturns in other countries, and some have a higher risk of currency devaluations.

Foreign Currency Risk. The performance of the Fund may be materially affected positively or negatively by foreign currency strength or weakness relative to the U.S. dollar, particularly if the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar.

Foreign Securities Risk. Investments in or exposure to foreign securities involve certain risks not associated with investments in or exposure to securities of U.S. companies. Foreign securities subject the Fund to the risks associated with investing in the particular country, including the political, regulatory, economic, social, diplomatic and other conditions or events occurring in the country or region, as well as risks associated with less developed custody and settlement practices. Foreign securities may be more volatile and less liquid than investments in securities of U.S. companies. The performance of the Fund may be negatively impacted by foreign currency strength or weakness relative to the U.S. dollar, particularly where the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar.

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within the specific geographic regions in which the Fund invests. The Fund’s net asset value may be more volatile than a more geographically diversified fund.

High-Yield Securities Risk. Securities rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated securities of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade securities. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated securities. High-yield securities are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities will tend to fall, and if interest rates fall, the values of debt securities will tend to rise. Changes in the value of a debt security usually will not affect the amount of income the Fund receives from it but may affect the value of the Fund's shares. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. As interest rates rise or spreads widen, the likelihood of prepayment decreases.

Issuer Risk. An issuer in which the Fund invests may perform poorly, and the value of its securities may therefore decline, which would negatively affect the Fund’s performance. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters or other events, conditions or factors.

Leverage Risk. Leverage occurs when the Fund increases its assets available for investment using borrowings, short sales, derivatives, or similar instruments or techniques. The use of leverage may make any change in the Fund's NAV even greater and thus result in increased volatility of returns. Because short sales involve borrowing securities and then selling them, the Fund’s short sales effectively leverage the Fund’s assets. The Fund's assets that are used as collateral to secure the Fund's obligations to return the securities sold short may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage can create an interest expense that may lower the Fund's overall returns. Leverage presents the opportunity for increased net income and capital gains, but also exaggerates the Fund's risk of loss. There can be no guarantee that a leveraging strategy will be successful.

Liquidity Risk. Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. The Fund may have to lower the selling price, sell other investments, or forego another, more appealing investment opportunity. Judgment plays a larger role in valuing these investments as compared to valuing more liquid investments.

Market Risk. Market risk refers to the possibility that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise. An investment in the Fund could lose money over short or even long periods.

Non-Diversified Fund Risk.  The Fund is non-diversified, which generally means that it will invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund's value will likely be more volatile than the value of a more diversified fund.

Prepayment and Extension Risk. Prepayment and extension risk is the risk that a loan, bond or other security or investment might be called or otherwise converted, prepaid or redeemed before maturity, and the portfolio managers may not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced yield to the Fund. As interest rates decrease or spreads narrow, the likelihood of prepayment increases. Conversely, extension risk is the risk that an unexpected rise in interest rates will extend the life of a mortgage- or asset-backed security beyond the prepayment time. If the Fund's investments are locked in at a lower interest rate for a longer period of time, the portfolio managers may be unable to capitalize on securities with higher interest rates or wider spreads.

Quantitative Model Risk. Investments selected using quantitative methods may perform differently from the market as a whole. There can be no assurance that these methodologies will enable the Fund to achieve its objective.

Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning.

Short Positions Risk. The Fund may establish short positions which introduce more risk to the Fund than long positions (where the Fund owns the instrument or other asset) because the maximum sustainable loss on an instrument or other asset purchased (held long) is limited to the amount paid for the instrument or other asset plus the transaction costs, whereas there is no maximum price of the shorted instrument or other asset when purchased in the open market. Therefore, in theory, short positions have unlimited risk. The Fund’s use of short positions in effect “leverages” the Fund. Leverage potentially exposes the Fund to greater risks of loss due to unanticipated market movements, which may magnify losses and increase the volatility of returns. To the extent the Fund takes a short position in a derivative instrument or other asset, this involves the risk of a potentially unlimited increase in the value of the underlying instrument or other asset.

Sovereign Debt Risk. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward international lenders, and the political constraints to which a sovereign debtor may be subject. Sovereign debt risk is increased for emerging market issuers.

Performance Information

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund’s Class A share performance (without sales charges) has varied for each full calendar year shown. If the sales charges were reflected, returns shown would be lower. The table below the bar chart compares the Fund’s returns (after applicable sales charges) for the periods shown with benchmark performance.

The performance of one or more share classes shown in the table below begins before the indicated inception date for such share class. The returns shown for each such share class include the returns of the Fund’s Class A shares (without applicable sales charges and adjusted to reflect the higher class-related operating expenses of such classes, where applicable) for periods prior to its inception date. Except for differences in annual returns resulting from differences in expenses and sales charges (where applicable), the share classes of the Fund would have substantially similar annual returns because all share classes of the Fund invest in the same portfolio of securities.

The after-tax returns shown in the table below are calculated using the highest historical individual U.S. federal marginal income tax rates and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-deferred accounts such as 401(k) plans or Individual Retirement Accounts (IRAs). The after-tax returns are shown only for Class A shares and will vary for other share classes. Returns after taxes on distributions and sale of Fund shares are higher than before-tax returns for certain periods shown because they reflect the tax benefit of capital losses realized on the redemption of Fund shares.
