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 Greater China Fund)	Class R4 Shares
Maximum sales charge (load) imposed on purchases, as a % of offering price	none
Maximum deferred sales charge (load) imposed on redemptions, as a % of the lower of the original purchase price or current net asset value	none

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

Annual Fund Operating Expenses (Columbia Greater China Fund)		Class R4 Shares

Total annual Fund operating expenses		1.30%

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 R4 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:

Expense Example (Columbia Greater China Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R4 Shares	132	412	713	1,568

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. During the most recent fiscal year, the Fund's portfolio turnover rate was 38% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies whose principal activities are located in the Greater China region. The Greater China region includes Hong Kong, The People's Republic of China, Taiwan and certain other countries. Columbia Management Investment Advisers, LLC, the Fund's investment adviser (the Investment Manager), will determine if a company's principal activities are located in the Greater China region by considering the company's country of organization, its primary stock exchange listing, the source of its revenues, the location of its assets and other factors.

The Fund may invest in companies that have market capitalizations of any size that the Investment Manager believes are undervalued or have the potential for long-term growth.

The Fund is non-diversified, which means that it can invest a greater percentage of its assets in a single issuer than can a diversified fund.

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:

• various measures of valuation, including price-to-cash flow, price-to-earnings, price-to-sales, and price-to-book value. The Investment Manager believes that companies with lower valuations are generally more likely to provide opportunities for capital appreciation.

• 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 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.

• overall economic and market conditions.

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 Fund's 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 may not produce the expected returns, 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, or fail to rise. 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, or fail to increase in value. 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.

• Greater China Regional Risk – The Greater China region consists of Hong Kong, The People's Republic of China and Taiwan, among other countries, and the Fund's investments in the region are particularly susceptible to risks in that region. Events in any one country within the region may impact the other countries in the region or the Asia region as a whole. As a result, events in the region will generally have a greater effect on the Fund than if the Fund were more geographically diversified, which could result in greater volatility and losses. Markets in the Greater China region can experience significant volatility due to social, regulatory and political uncertainties.

• 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.

• 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 Investment Manager'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.

• 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 (larger 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 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.

• Currency Risk – Securities denominated in non-U.S. dollar 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.

• Emerging Market Securities Risk – Securities issued by foreign governments or companies in emerging market countries, like Russia and 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 may 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.

Performance Information

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. Class R4 shares had not commenced operations prior to the date of this prospectus; therefore, performance information for this class is not yet available. The performance of Class A shares, which have been outstanding as long as any other share class of the Fund, is shown in the bar chart and average annual total return table. Except for differences in annual returns resulting from differences in expenses and sales charges (where applicable), this class of shares would have annual returns substantially similar to those of Class A shares, which are not offered in this prospectus, because all classes of the Fund's shares invest in the same portfolio of securities.

The Fund's past performance (before and after taxes) is no guarantee of how the Fund will perform in the future. Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting www.columbiamanagement.com.

The bar chart shows how the Fund's Class A share performance (without sales charges) has varied for each full calendar year shown. If the sales charges were reflected, returns shown would be lower.
