Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees (Columbia Active Portfolios®—Select Large Cap Growth Fund)	Class A Shares
Maximum sales charge (load) imposed on purchases, as a % of offering price
Maximum deferred sales charge (load) imposed on redemptions, as a % of the lower of the original purchase price or net asset value

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (Columbia Active Portfolios®—Select Large Cap Growth Fund)		Class A Shares
Management fees		0.75%
Distribution and/or service (Rule 12b-1) fees		0.25%
Other expenses	[1]	0.26%
Total annual Fund operating expenses		1.26%
Fee waivers and/or reimbursements	[2]	(0.07%)
Total annual Fund operating expenses after fee waivers and/or reimbursements		1.19%

Example

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 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 July 31, 2014, they are only reflected in the 1 year example and the first two years of the 3 year example.

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

Expense Example (Columbia Active Portfolios®—Select Large Cap Growth Fund) (USD $)	1 Year	3 Years
Class A Shares	121	385

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

Portfolio Turnover

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. Because the Fund is newly organized, portfolio turnover rate is not yet available.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets in common stocks of U.S. and foreign companies that have market capitalizations in the range of companies in the Russell 1000 Growth Index at the time of purchase (between $835 million and $501.62 billion as of February 29, 2012). The Fund invests primarily in common stocks of companies that Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Investment Manager) believes have the potential for long-term growth.

The Fund may invest directly in foreign securities or indirectly through depositary receipts. Depositary receipts are receipts issued by a bank or trust company and evidence ownership of underlying securities issued by foreign companies.

The Fund will not concentrate its assets in any single industry but may from time to time emphasize one or more economic sectors in selecting its investments and may invest more than 25% of its assets in companies in each of the technology and health care sectors.

The Investment Manager combines fundamental and quantitative analysis with risk management in identifying investment opportunities and constructing the Fund's portfolio. The Investment Manager 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 Investment Manager may sell a security when the security's price reaches a target set by the Investment Manager; if the Investment Manager 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.

Principal Risks

• Investment Strategy Risk – The Investment Manager 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 Investment Manager in using these strategies may not produce the returns expected by the Investment Manager, 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.

• 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.

• 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.

• Health Care Sector Risk – Companies in the health care sector are subject to extensive government regulation. Their profitability can be affected significantly and adversely by restrictions on government reimbursement for medical expenses, government approval of medical products and services, competitive pricing pressures, an increased emphasis on outpatient and other alternative services and other factors. Patent protection is integral to the success of companies in the health care 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 medical products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). Companies in the health care sector also potentially are subject to extensive product liability and other similar litigation. Companies in the health care sector are affected by the rising cost of medical products and services, and the effects of such rising costs can be particularly pronounced for companies that are dependent on a relatively limited number of products or services. Medical products also frequently become obsolete due to industry innovation or other causes. Because the Fund invests a significant portion of its net assets in the equity securities of health care companies, the Fund's price may be more volatile than a fund that is invested in a more diverse range of market sectors.

• Focused Portfolio Risk - The Fund, because it may invest in a limited number of companies, may have more volatility and is considered to have more risk than a fund that invests in a greater number of companies because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund's net asset value. To the extent the Fund invests its assets in fewer securities, the Fund is subject to greater risk of loss if any of those securities declines in price.
