[3]	Columbia Management Investment Advisers, LLC (the Adviser) and certain of its affiliates have contractually agreed to waive fees or reimburse expenses, through June 30, 2012, so that the Fund's ordinary operating expenses (excluding certain expenses, such as transaction costs and brokerage commissions, interest, taxes, acquired fund fees and expenses, and extraordinary expenses), after giving effect to any balance credits or overdraft charges from the Fund's custodian, do not exceed the annual rates of 1.11%, 1.86%, 1.86% and 0.75% of the Fund's average daily net assets attributable to Class A, Class B, Class C and Class I shares, respectively. This expense arrangement is made pursuant to a fee waiver and expense cap agreement that may be modified or amended only with approval from all parties to such arrangements, including the Fund and the Adviser.

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 Class A, Class B, Class C or Class I shares of the Fund 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 table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire on June 30, 2012, they are only reflected in the 1 year example and the first year of the 3, 5 and 10 year examples.

Based on the assumptions listed above, your costs would be:

This expense arrangement is made pursuant to a fee waiver and expense cap agreement that may be modified or amended only with approval from all parties to such arrangements, including the Fund and the Adviser.

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 Class Z shares of the Fund 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 table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire on June 30, 2012, they are only reflected in the 1 year example and the first year of the 3, 5 and 10 year examples.

Based on the assumptions listed above, your costs would be:

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 118% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in convertible securities. The Fund may invest up to 15% of its total assets in Eurodollar convertible securities and up to an additional 20% of its total assets in foreign securities. Most convertible securities are not investment grade-rated. Convertible securities rated below investment grade may be referred to as "junk bonds." The Fund also may invest in other equity securities.

Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), looks for opportunities to participate in the potential growth of underlying common stocks, while seeking to earn income that is generally higher than the income those stocks provide. The Fund may sell common stocks short against positions in which the Fund has directly invested in convertible securities with no more than 10% of its assets.

The Adviser considers a number of factors in identifying investment opportunities and constructing the Fund's portfolio, including, among others:

overall economic and market conditions;
the financial condition and management of a company, including its competitive position, the quality of its balance sheet and earnings, its future prospects, and the potential for growth and stock price appreciation; and
the characteristics of the security, including its conversion feature.

The Adviser tries to limit conversion costs and generally sells securities when they take on the trading characteristics of the underlying common stock. The Adviser also may convert securities to common shares when it believes it's appropriate to do so.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Convertible Securities Risk -- Convertible securities are subject to the usual risks associated with debt securities, such as interest rate risk and credit risk. Convertible securities also react to changes in the value of the common stock into which they convert. Because the value of a convertible security can be influenced by both interest rates and the common stock's market movements, a convertible security generally is not as sensitive to interest rates as a similar debt security, and generally will not vary in value in response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would typically be paid before the company's common stockholders but after holders of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it otherwise would choose to do so, which may decrease the Fund's return.

Low and Below Investment Grade Securities Risk -- Debt securities with the lowest investment grade rating (e.g., BBB by Standard & Poor's, a division of the McGraw-Hill Companies, Inc. (S&P), or Fitch, Inc. (Fitch) or Baa by Moody's Investors Service, Inc. (Moody's)), or that are below investment grade (which are commonly referred to as "junk bonds") (e.g., BB or below by S&P or Fitch or Ba by Moody's) are more speculative than securities with higher ratings. These securities tend to be more sensitive to credit risk, particularly during a downturn in the economy, which is more likely to weaken the ability of the issuers to make principal and interest payments than higher-rated securities. These securities typically pay a premium -- a higher interest rate or yield -- because of the increased risk of loss, including default. These securities also are generally less liquid than higher-rated securities. The securities ratings provided by Moody's, S&P and Fitch are based on analyses by these ratings agencies of the credit quality of the securities and may not take into account every risk related to whether interest or principal will be timely repaid.

Interest Rate Risk -- Debt securities are subject to interest rate risk. 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. Interest rate risk is generally greater for debt securities with longer maturities/durations.

Credit Risk -- Credit risk applies to most debt securities, but is generally not a factor for obligations backed by the "full faith and credit" of the U.S. Government. The Fund could lose money if the issuer of a debt security owned by the Fund is unable or perceived to be unable to pay interest or repay principal when it becomes due. Various factors could affect the issuer's actual or perceived willingness or ability to make timely interest or principal payments, including changes in the issuer's financial condition or in general economic conditions. Debt securities backed by an issuer's taxing authority may be subject to legal limits on the issuer's power to increase taxes or otherwise to raise revenue, or may be dependent on legislative appropriation or government aid. Certain debt securities are backed only by revenues derived from a particular project or source, rather than by an issuer's taxing authority, and thus may have a greater risk of default.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Short Sales Risk -- A short sale generally involves the sale by the Fund of a security it does not own with the expectation of acquiring the security at a later time at a lower price, but can involve the sale by the Fund of a security it does own. In order to short sell a common stock, the Fund must borrow, buy or already hold the security in order to make delivery to the counterparty. If the Fund borrows the security, it then is obligated to replace the security at some later time. The price of the security at such time may be higher or lower than the price at which the security was sold short by the Fund. Therefore, the Fund bears the risk that the price of the security at the time of replacement has not decreased. Short sales can potentially involve unlimited loss, as the market price of securities sold short may continue to increase, although the Fund may be able to limit any such losses by purchasing the securities sold short. There also is a risk that the Fund may experience difficulty purchasing the security necessary for replacement if the security does not have a liquid market at the time that the replacement must occur or that an event may occur.

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 Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 79% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies that have market capitalizations in the range of the companies in the Russell 1000 Value Index at the time of purchase (between $243 million and $425 billion as of May 31, 2011), that Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), believes are undervalued and have the potential for long-term growth. The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks and also may invest in real estate investment trusts.

The Adviser combines fundamental and quantitative analysis with risk management in identifying value opportunities and constructing the Fund's portfolio. The Adviser considers, among other factors:

businesses that are believed to be fundamentally sound and undervalued due to investor indifference, investor misperception of company prospects, or other factors;
various measures of valuation, including price-to-cash flow, price-to-earnings, price-to-sales, and price-to-book value. The Adviser believes that companies with lower valuations are generally more likely to provide opportunities for capital appreciation;
a company's current operating margins relative to its historic range and future potential; and
potential indicators of stock price appreciation, such as anticipated earnings growth, company restructuring, changes in management, business model changes, new product opportunities, or anticipated improvements in macroeconomic factors.

The Adviser may sell a security when the security's price reaches a target set by the Adviser; if the Adviser believes that there is deterioration in the issuer's financial circumstances or fundamental prospects, or that other investments are more attractive; or for other reasons.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Value Securities Risk -- Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the Adviser's future value assessment of that security, or may decline. There is also a risk that it may take longer than expected for the value of these investments to rise to the believed value. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Real Estate Investment Trusts Risk -- Real estate investment trusts (REITs) are entities that either own properties or make construction or mortgage loans, and also may include operating or finance companies. The value of REIT shares is affected by, among other factors, changes in the value of the underlying properties owned by the REIT and/or by changes in the prospect for earnings and/or cash flow growth of the REIT itself. In addition, certain of the risks associated with general real estate ownership apply to the Fund's REIT investments, including risks related to general and local economic conditions, possible lack of availability of financing and changes in interest rates.

Sector Risk -- At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

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 returns shown for Class R shares include the returns of the Fund's Class A shares for periods prior to January 23, 2006, the date Class R shares were initially offered by the Fund. The returns shown do not reflect any differences in expenses. If differences in expenses had been reflected, the returns shown for Class R shares for periods prior to January 23, 2006 would be lower.

The returns shown for Class I shares include the returns of the Fund's Class Z shares, which are not offered in this prospectus, for periods prior to September 27, 2010, the date Class I shares were initially offered by the Fund. The returns shown for Class W shares include the returns of the Fund's Class A shares (without applicable sales charges), for periods prior to September 27, 2010, the date Class W shares were initially offered by the Fund. Class I shares would have annual returns substantially similar to those of Class Z shares, and Class W shares would have annual returns substantially similar to those of Class A shares (without applicable sales charges), because each of the Fund's share classes is invested in the same portfolio of securities, and its returns would differ only to the extent that its expenses differ. The returns shown for Class Z shares and Class A shares have not been adjusted to reflect any differences in expenses between Class I shares and Class Z shares or between Class W shares and Class A shares, respectively. The Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

[3]	Columbia Management Investment Advisers, LLC (the Adviser) and certain of its affiliates have contractually agreed to waive fees or reimburse expenses, through June 30, 2012, so that the Fund's ordinary operating expenses (excluding certain expenses, such as transaction costs and brokerage commissions, interest, taxes, acquired fund fees and expenses, and extraordinary expenses), after giving effect to any balance credits or overdraft charges from the Fund's custodian, do not exceed the annual rate of 0.86% of the Fund's average daily net assets attributable to Class Z shares. This expense arrangement is made pursuant to a fee waiver and expense cap agreement that may be modified or amended only with approval from all parties to such arrangements, including the Fund and the Adviser.

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 Class Z shares of the Fund 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 table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire on June 30, 2012, they are only reflected in the 1 year example and the first year of the 3, 5 and 10 year examples.

Based on the assumptions listed above, your costs would be:

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 79% of the average value of its portfolio.

potential indicators of stock price appreciation, such as anticipated earnings growth, company restructuring, changes in management, business model changes, new product opportunities, or anticipated improvements in macroeconomic factors.

The Adviser may sell a security when the security's price reaches a target set by the Adviser; if the Adviser believes that there is deterioration in the issuer's financial circumstances or fundamental prospects, or that other investments are more attractive; or for other reasons.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Value Securities Risk -- Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the Adviser's future value assessment of that security, or may decline. There is also a risk that it may take longer than expected for the value of these investments to rise to the believed value. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Real Estate Investment Trusts Risk -- Real estate investment trusts (REITs) are entities that either own properties or make construction or mortgage loans, and also may include operating or finance companies. The value of REIT shares is affected by, among other factors, changes in the value of the underlying properties owned by the REIT and/or by changes in the prospect for earnings and/or cash flow growth of the REIT itself. In addition, certain of the risks associated with general real estate ownership apply to the Fund's REIT investments, including risks related to general and local economic conditions, possible lack of availability of financing and changes in interest rates.

Sector Risk -- At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

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 Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

Best and Worst Quarterly Returns During this Period

Best:   2nd quarter 2003:     16.53%
Worst:  4th quarter 2008:    -21.95%

The table compares the Fund's returns for each period with those of the Russell 1000 Value Index, which measures the performance of those Russell 1000 Index companies with lower price-to-book ratios and lower forecasted growth values.

The after-tax returns shown in the table above 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).

Example

Expense Example (Columbia Mid Cap Value Fund) (Columbia Mid Cap Value Fund ABCIRR4W) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A Shares	685	919	1,172	1,892
Class B Shares	693	897	1,226	2,027

Class R4 Shares	104	325	563	1,248
Class W Shares	117	365	633	1,398

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 50% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies that have market capitalizations in the range of the companies in the Russell Midcap Value Index at the time of purchase (between $243 million and $51 billion as of May 31, 2011), that Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), believes are undervalued and have the potential for long-term growth. The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks and also may invest in real estate investment trusts.

The Adviser combines fundamental and quantitative analysis with risk management in identifying value opportunities and constructing the Fund's portfolio. The Adviser considers, among other factors:

businesses that are believed to be fundamentally sound and undervalued due to investor indifference, investor misperception of company prospects, or other factors;
various measures of valuation, including price-to-cash flow, price-to-earnings, price-to-sales, and price-to-book value. The Adviser believes that companies with lower valuations are generally more likely to provide opportunities for capital appreciation;
a company's current operating margins relative to its historic range and future potential; and
potential indicators of stock price appreciation, such as anticipated earnings growth, company restructuring, changes in management, business model changes, new product opportunities, or anticipated improvements in macroeconomic factors.

The Adviser may sell a security when the security's price reaches a target set by the Adviser; if the Adviser believes that there is deterioration in the issuer's financial circumstances or fundamental prospects, or that other investments are more attractive; or for other reasons.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors.

There is also a risk that it may take longer than expected for the value of these investments to rise to the believed value. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Smaller Company Securities Risk -- Securities of small- or mid-capitalization companies ("smaller companies") can, in certain circumstances, have a higher potential for gains than securities of large-capitalization companies but may also have more risk. For example, smaller companies may be more vulnerable to market downturns and adverse business or economic events than larger, more established companies because they may have more limited financial resources and business operations. These companies are also more likely than large-capitalization companies ("larger companies") to have more limited product lines and operating histories and to depend on smaller management teams. Their securities may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. In addition, some smaller companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices.

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 inception date of the Fund's Class A shares, Class B shares, and Class C shares is November 20, 2001, and the inception date of the Fund's Class R shares is January 23, 2006. The returns shown for Class R shares include the returns of Class A shares for periods prior to January 23, 2006. The returns shown reflect applicable sales charges, but have not been adjusted to reflect any differences in expenses. If differences in expenses were reflected, the returns shown for periods prior to January 23, 2006 would be lower.

The returns shown for Class I shares and Class W shares include the returns of the Fund's Class Z shares, which are not offered in this prospectus, and the Fund's Class A shares (without applicable sales charges), respectively, for periods prior to September 27, 2010, when Class I shares and Class W shares commenced operations. Class R4 shares commenced operations on March 7, 2011; therefore, calendar year performance for this share class is not yet available. The average annual total return table includes the returns of Class A shares without deduction of applicable sales charges. Class I shares would have annual returns substantially similar to those of Class Z shares, and Class W shares and Class R4 shares would have annual returns substantially similar to those of Class A shares (without applicable sales charges), because each of the Fund's share classes is invested in the same portfolio of securities, and its returns would differ only to the extent that its expenses differ. The returns shown have not been adjusted to reflect any differences in expenses between Class I shares and Class Z shares, or between Class R4 shares or Class W shares and Class A shares, respectively. The Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

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 Class Z shares of the Fund 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 table above.

Based on the assumptions listed above, your costs would be:

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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.

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 60% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies that have market capitalizations in the range of the companies in the Russell 2000 Value Index at the time of purchase (between $27 million and $5.4 billion as of May 31, 2011), that Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), believes are undervalued and have the potential for long-term growth. The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks and also may invest in real estate investment trusts.

The Adviser may sell a security when the security's price reaches a target set by the Adviser; if the Adviser believes that there is deterioration in the issuer's financial circumstances or fundamental prospects, or that other investments are more attractive; or for other reasons.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Value Securities Risk -- Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the Adviser's future value assessment of that security, or may decline. There is also a risk that it may take longer than expected for the value of these investments to rise to the believed value.

In addition, some smaller companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Real Estate Investment Trusts Risk -- Real estate investment trusts (REITs) are entities that either own properties or make construction or mortgage loans, and also may include operating or finance companies. The value of REIT shares is affected by, among other factors, changes in the value of the underlying properties owned by the REIT and/or by changes in the prospect for earnings and/or cash flow growth of the REIT itself. In addition, certain of the risks associated with general real estate ownership apply to the Fund's REIT investments, including risks related to general and local economic conditions, possible lack of availability of financing and changes in interest rates.

Sector Risk -- At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

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 returns shown for Class I shares prior to September 27, 2010, the date Class I shares commenced operations, are the returns of Class Z shares of the Fund, which are not offered in this prospectus. Class I shares would have annual returns substantially similar to those of Class Z shares because each of the Fund's share classes is invested in the same portfolio of securities, and its returns would differ only to the extent that its expenses differ. The returns shown have not been adjusted to reflect any differences in expenses between Class I shares and Class Z shares. The Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

Columbia Management Investment Advisers, LLC (the Adviser) and certain of its affiliates have contractually agreed to waive fees or reimburse expenses, through June 30, 2012, so that the Fund's ordinary operating expenses (excluding certain expenses, such as transaction costs and brokerage commissions, interest, taxes, acquired fund fees and expenses, and extraordinary expenses), after giving effect to any balance credits or overdraft charges from the Fund's custodian, do not exceed the annual rates of 1.29%, 2.04%, 2.04%, 0.87%, 1.54% and 1.29% of the Fund's average daily net assets attributable to Class A, Class B, Class C, Class I, Class R and Class W shares, respectively. This expense arrangement is made pursuant to a fee waiver and expense cap agreement that may be modified or amended only with approval from all parties to such arrangements, including the Fund and the Adviser.

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 Class A, Class B, Class C, Class I, Class R or Class W shares of the Fund 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 table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire on June 30, 2012, they are only reflected in the 1 year example and the first year of the 3, 5 and 10 year examples.

Based on the assumptions listed above, your costs would be:

Columbia Management Investment Advisers, LLC (the Adviser) and certain of its affiliates have contractually agreed to waive fees or reimburse expenses, through June 30, 2012, so that the Fund's ordinary operating expenses (excluding certain expenses, such as transaction costs and brokerage commissions, interest, taxes, acquired fund fees and expenses, and extraordinary expenses), after giving effect to any balance credits or overdraft charges from the Fund's custodian, do not exceed the annual rate of 1.04% of the Fund's average daily net assets attributable to Class Z shares. This expense arrangement is made pursuant to a fee waiver and expense cap agreement that may be modified or amended only with approval from all parties to such arrangements, including the Fund and the Adviser.

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 Class Z shares of the Fund 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 table above.

Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire on June 30, 2012, they are only reflected in the 1 year example and the first year of the 3, 5 and 10 year examples.

Based on the assumptions listed above, your costs would be:

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 67% of the average value of its portfolio.

Under normal circumstances, the Fund invests primarily in equity securities of large-capitalization companies that have market capitalizations of $5 billion or more at the time of purchase. The Fund generally holds a core position of between 35 and 50 common stocks. The number of securities held by the Fund occasionally may exceed this range, such as when the Fund is accumulating new positions, phasing out and replacing existing positions, or responding to exceptional market conditions. The Fund may invest up to 25% of its total assets in foreign securities, including in emerging market securities.

The core investments of the Fund generally may include established companies and securities that are expected to offer long-term growth potential. However, the Fund's portfolio also may include securities of less mature companies, securities with more aggressive growth characteristics, and securities of companies undergoing significant positive developments, such as the introduction of a new product line, the appointment of a new management team, or an acquisition.

Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), has engaged an investment subadviser - Marsico Capital Management, LLC (Marsico) - which manages the Fund on a day-to-day basis, although the Adviser retains general investment management responsibility for the management of the Fund. In selecting investments for the Fund, Marsico uses an approach that combines "top-down" macro-economic analysis with "bottom-up" stock selection.

As part of its "top-down" investment approach, Marsico generally considers certain macro-economic factors to formulate the backdrop for security selection. These factors may include, without limitation, interest rates, currency movements, inflation, monetary policy, demographics, the regulatory environment, and the global competitive landscape. Marsico may also examine other factors that may include, without limitation, the most attractive global investment opportunities, industry consolidation, and the sustainability of financial trends. As a result of this "top-down" analysis, Marsico seeks to identify sectors, industries and companies that may benefit from the overall trends Marsico has observed.

Marsico then looks for individual companies or securities that are expected to offer earnings growth potential that may not be recognized by the market at large. In determining whether a particular company or security may be a suitable investment, Marsico may focus on any of a number of different attributes that may include, without limitation, the company's specific market expertise or dominance; its franchise durability and pricing power; solid fundamentals (e.g., a strong balance sheet, improving returns on equity, the ability to generate free cash flow, apparent use of conservative accounting standards and transparent financial disclosure); strong and ethical management; commitment to shareholder interests; reasonable valuations in the context of projected growth rates; current income and other indications that a company or security may be an attractive investment prospect. This process is called "bottom-up" stock selection.

As part of this fundamental, "bottom-up" research, Marsico may visit with various levels of a company's management and conduct other research to gain thorough knowledge of the company. Marsico also may prepare detailed earnings and cash flow models of companies. These models may assist Marsico in projecting potential earnings growth, current income and other important company financial characteristics under different scenarios. Each model is typically customized to follow a particular company and is generally intended to replicate and describe a company's past, present and potential future performance. The models may include quantitative information and detailed narratives that reflect updated interpretations of corporate data and company and industry developments.

Marsico may reduce or sell the Fund's investments in portfolio securities if, in the opinion of Marsico, a security's fundamentals change substantially, its price appreciation leads to substantial overvaluation in relation to Marsico's estimates of future earnings and cash flow growth, the company appears unlikely to realize its growth potential, more attractive investment opportunities appear elsewhere or for other reasons.

In managing the Fund's assets, Marsico seeks to remain mindful of the tax consequences that investment decisions may have on shareholders. However, if Marsico determines, for example, that a portfolio security should be sold, the holding will be sold notwithstanding any possible tax consequences.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Growth Securities Risk -- Because growth securities typically trade at a higher multiple of earnings than other types of securities, the market values of growth securities may be more sensitive to changes in current or expected earnings than the market values of other types of securities. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Emerging Market Securities Risk -- Securities issued by foreign governments or companies in emerging market countries, like those in Eastern Europe, the Middle East, Asia, Latin America or Africa, 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 social, political and economic development. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity 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, which makes them more sensitive to world commodity prices and economic downturns in other countries. Some emerging market countries have a higher risk of currency devaluations, and some of these countries may experience periods of high inflation or rapid changes in inflation rates.

Currency Risk -- Securities denominated in different currencies are subject to the risk that, for example, if the value of a foreign currency were to decline against the U.S. dollar, such decline would reduce the U.S. dollar value of any securities held by the Fund denominated in that currency.

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 Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

Class I Shares	79	246	428	954
Class W Shares	118	377	656	1,451

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 171% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in securities of companies that have market capitalizations in the range of companies in the Standard & Poor's (S&P) 500® Index at the time of purchase (between $1.7 billion and $413.9 billion as of May 31, 2011). The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks, preferred stocks and convertible securities like warrants and rights. The Fund may invest in securities of companies in the technology sector and also may invest in exchange-traded funds.

The Fund may invest in derivatives, including options and other derivative instruments. The Fund may invest in derivatives for both hedging and non-hedging purposes, including, for example, to seek to enhance returns or as a substitute for a position in an underlying asset.

Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), combines fundamental and quantitative analysis with risk management in identifying investment opportunities and constructing the Fund's portfolio. The Adviser considers, among other factors:

overall economic and market conditions.
the financial condition and management of a company, including its competitive position, the quality of its balance sheet and earnings, its future prospects, and the potential for growth and stock price appreciation.

The Adviser may sell a security when the security's price reaches a target set by the Adviser; if the Adviser believes that there is deterioration in the issuer's financial circumstances or fundamental prospects, or that other investments are more attractive; or for other reasons.

The Fund's investment strategy may involve the frequent trading of portfolio securities. This may cause the Fund to incur higher transaction costs (which may adversely affect the Fund's performance) and may increase taxable distributions for shareholders.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Growth Securities Risk -- Because growth securities typically trade at a higher multiple of earnings than other types of securities, the market values of growth securities may be more sensitive to changes in current or expected earnings than the market values of other types of securities. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Value Securities Risk -- Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the Adviser's future value assessment of that security, or may decline. There is also a risk that it may take longer than expected for the value of these investments to rise to the believed value. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Convertible Securities Risk -- Convertible securities are subject to the usual risks associated with debt securities, such as interest rate risk and credit risk. Convertible securities also react to changes in the value of the common stock into which they convert. Because the value of a convertible security can be influenced by both interest rates and the common stock's market movements, a convertible security generally is not as sensitive to interest rates as a similar debt security, and generally will not vary in value in response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would typically be paid before the company's common stockholders but after holders of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it otherwise would choose to do so, which may decrease the Fund's return.

Investing in Other Funds Risk -- The performance of the funds, including exchange-traded funds, in which the Fund invests could be adversely affected if other entities that invest in the same funds make relatively large investments or redemptions in the funds. In addition, because the expenses and costs of the funds are shared by investors in the underlying fund, redemptions by other investors in the underlying fund could result in decreased economies of scale and increased operating expenses for the underlying funds. These transactions might also result in higher brokerage, tax or other costs for the Fund. This risk may be particularly important when one investor owns a substantial portion of any underlying fund. If an underlying fund pays fees to the Adviser or its affiliates, this could result in the Adviser having a potential conflict of interest in selecting the underlying funds in which the Fund invests or in determining the percentage of the Fund's investments allocated to each underlying fund. There are also circumstances in which the Adviser's fiduciary duties to the Fund may conflict with its fiduciary duties to the underlying funds for which it serves as investment manager.

Technology Sector Risk -- Companies in the technology sector are subject to significant competitive pressures, such as aggressive pricing of their products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of technology companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in the technology sector, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many technology companies have limited operating histories. Prices of these companies' securities historically have been more volatile than other securities, especially over the short term. Because the Fund invests a significant portion of its net assets in the equity securities of technology companies, the Fund's price may be more volatile than a fund that is invested in a more diverse range of market sectors.

Derivatives Risk -- Derivatives are financial contracts whose values are, for example, based on (or "derived" from) traditional securities (such as a stock or bond), assets (such as a commodity like gold or a foreign currency), reference rates (such as LIBOR) or market indices (such as the Standard & Poor's (S&P) 500® Index). Derivatives involve special risks and may result in losses or may limit the Fund's potential gain from favorable market movements. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have lost had it invested in the underlying security or other asset. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility, among other consequences. The use of derivatives may also increase the amount of taxes payable by shareholders holding shares in a taxable account. Other risks arise from the Fund's potential inability to terminate or to sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or to sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The use of derivatives also involves the risks of mispricing or improper valuation and that changes in the value of the derivative may not correlate perfectly with the underlying security, asset, reference rate or index. The Fund also may not be able to find a suitable derivative transaction counterparty, and thus may be unable to engage in derivative transactions when it is deemed favorable to do so, or at all. For more information on the risks of derivative investments and strategies, see the Statement of Additional Information.

Frequent Trading Risk -- Frequent trading of investments increases the possibility that the Fund will realize taxable capital gains (including short-term capital gains, which are generally taxable at higher rates than long-term capital gains for U.S. federal income tax purposes), which could reduce the Fund's after-tax return. Frequent trading can also mean higher brokerage and other transaction costs, which could reduce the Fund's return.

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 returns shown for Class I shares include the returns of the Fund's Class Z shares, which are not offered in this prospectus, for periods prior to September 27, 2010, the date Class I shares were initially offered by the Fund. The returns shown for Class W shares include the returns of the Fund's Class A shares (without applicable sales charges), for periods prior to September 27, 2010, the date Class W shares were initially offered by the Fund. Class I shares would have annual returns substantially similar to those of Class Z shares, and Class W shares would have annual returns substantially similar to those of Class A shares (without applicable sales charges), because each of the Fund's share classes is invested in the same portfolio of securities, and its returns would differ only to the extent that its expenses differ. The returns shown for Class Z shares and Class A shares have not been adjusted to reflect any differences in expenses between Class I shares and Class Z shares or between Class W shares and Class A shares, respectively. The Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

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 Class Z shares of the Fund 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 table above.

Based on the assumptions listed above, your costs would be:

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 77% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities. These investments mostly consist of equity securities of large-capitalization companies that have market capitalizations of $5 billion or more at the time of purchase. The Fund, which is non-diversified, generally will hold a core position of between 20 and 30 common stocks that are believed to have potential for long-term growth. The number of securities held by the Fund occasionally may exceed this range, such as when the Fund is accumulating new positions, phasing out and replacing existing positions, or responding to exceptional market conditions. The Fund may invest up to 25% of its total assets in foreign securities, including in emerging market securities.

The core investments of the Fund generally may include established companies and securities that are expected to offer long-term growth potential. However, the Fund's portfolio also may include securities of less mature companies, securities with more aggressive growth characteristics, and securities of companies undergoing significant positive developments, such as the introduction of a new product line, the appointment of a new management team, or an acquisition.

Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Adviser), has engaged an investment subadviser - Marsico Capital Management, LLC (Marsico) - which manages the Fund on a day-to-day basis, although the Adviser retains general investment management responsibility for the management of the Fund. In selecting investments for the Fund, Marsico uses an approach that combines "top-down" macro-economic analysis with "bottom-up" stock selection.

As part of its "top-down" investment approach, Marsico generally considers certain macro-economic factors to formulate the backdrop for security selection. These factors may include, without limitation, interest rates, currency movements, inflation, monetary policy, demographics, the regulatory environment, and the global competitive landscape. Marsico may also examine other factors that may include, without limitation, the most attractive global investment opportunities, industry consolidation, and the sustainability of financial trends. As a result of this "top-down" analysis, Marsico seeks to identify sectors, industries and companies that may benefit from the overall trends Marsico has observed.

Marsico then looks for individual companies or securities that are expected to offer earnings growth potential that may not be recognized by the market at large. In determining whether a particular company or security may be a suitable investment, Marsico may focus on any of a number of different attributes that may include, without limitation, the company's specific market expertise or dominance; its franchise durability and pricing power; solid fundamentals (e.g., a strong balance sheet, improving returns on equity, the ability to generate free cash flow, apparent use of conservative accounting standards and transparent financial disclosure); strong and ethical management; commitment to shareholder interests; reasonable valuations in the context of projected growth rates; current income and other indications that a company or security may be an attractive investment prospect. This process is called "bottom-up" stock selection.

As part of this fundamental, "bottom-up" research, Marsico may visit with various levels of a company's management and conduct other research to gain thorough knowledge of the company. Marsico also may prepare detailed earnings and cash flow models of companies. These models may assist Marsico in projecting potential earnings growth, current income and other important company financial characteristics under different scenarios. Each model is typically customized to follow a particular company and is generally intended to replicate and describe a company's past, present and potential future performance. The models may include quantitative information and detailed narratives that reflect updated interpretations of corporate data and company and industry developments.

Marsico may reduce or sell the Fund's investments in portfolio securities if, in the opinion of Marsico, a security's fundamentals change substantially, its price appreciation leads to substantial overvaluation in relation to Marsico's estimates of future earnings and cash flow growth, the company appears unlikely to realize its growth potential, more attractive investment opportunities appear elsewhere or for other reasons.

In managing the Fund's assets, Marsico seeks to remain mindful of the tax consequences that investment decisions may have on shareholders. However, if Marsico determines, for example, that a portfolio security should be sold, the holding will be sold notwithstanding any possible tax consequences.

Investment Strategy Risk -- The Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. There is no assurance that the Fund will achieve its investment objective. Investment decisions made by the Adviser in using these strategies may not produce the returns expected by the Adviser, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk -- Market risk refers to the possibility that the market values of securities that the Fund holds will fall, sometimes rapidly or unpredictably. Security values may fall because of factors affecting individual companies, industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Foreign Securities Risk -- Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or in U.S. dollars, without a change in the intrinsic value of those securities. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial fees and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose potentially confiscatory withholding or other taxes, which could reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies.

Growth Securities Risk -- Because growth securities typically trade at a higher multiple of earnings than other types of securities, the market values of growth securities may be more sensitive to changes in current or expected earnings than the market values of other types of securities. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Emerging Market Securities Risk -- Securities issued by foreign governments or companies in emerging market countries, like those in Eastern Europe, the Middle East, Asia, Latin America or Africa, 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 social, political and economic development. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity 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, which makes them more sensitive to world commodity prices and economic downturns in other countries. Some emerging market countries have a higher risk of currency devaluations, and some of these countries may experience periods of high inflation or rapid changes in inflation rates.

Non-Diversified Mutual Fund Risk -- The Fund is non-diversified, which generally means that it may 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 more diversified funds. The Fund may not operate as a non-diversified fund at all times.

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 Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.

Remember this is an example only. Your actual costs may be higher or lower.

The Fund pays 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 87% of the average value of its portfolio.

The Fund invests primarily in equity securities of companies of any capitalization size and generally will hold a core position of between 35 and 50 common stocks. The number of securities held by the Fund may occasionally exceed this range at times such as when the Fund is accumulating new positions, phasing out and replacing existing positions, or responding to exceptional market conditions. The Fund may invest without limit in foreign securities, including in emerging market securities. The Fund also may invest in foreign currency exchange contracts to convert foreign currencies to and from the U.S. dollar, and to hedge against changes in foreign currency exchange rates.
