FUNDamentals™

Fixed Income Funds

Fixed income funds invest primarily in debt securities that may be issued by governments, companies or special purpose entities. Debt securities pay interest at a specified rate on a specified date or dates, and the principal is paid when the security reaches maturity. Prices of debt securities may appreciate as interest rates fall but may lose value as interest rates rise.

Fixed income funds may be a suitable investment for you if you:

n are looking for a regular stream of income, and

n are prepared to bear the risks associated with investments in debt securities.

LOGO Investment Objective

The Fund seeks total return, consisting of current income and capital appreciation.

LOGO Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of net assets in below investment grade corporate debt securities. These securities commonly are referred to as “junk bonds” and generally will be rated below investment grade by at least one nationally recognized rating service or unrated but determined by the Advisor to be of comparable quality. The Fund may invest in debt securities issued by foreign governments, companies or other entities, including in emerging market countries. The Fund also may invest in equity securities, including common stocks, preferred stocks, warrants and debt securities convertible into common stocks.

The Fund may invest in derivatives, including futures, options, swap contracts 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. The Fund also may invest in private placements.

The Advisor evaluates a number of factors in identifying investment opportunities and constructing the Fund’s portfolio. The Advisor considers local, national and global economic conditions, market conditions, interest rate movements, and other relevant factors to determine the allocation of the Fund’s assets among different issuers, industry sectors and maturities.

The Advisor, in connection with selecting individual investments for the Fund, evaluates a security based on its potential to generate income and/or capital appreciation. The Advisor considers, among other factors, the creditworthiness of the issuer of the security and the various features of the security, such as its coupon, yield, maturity, any call features and value relative to other securities.

The Advisor may sell a security if the Advisor believes that there is deterioration in the issuer’s financial condition, or that other investments are more attractive; if there is deterioration in a security’s credit rating; or for other reasons.

The Fund’s policy regarding the 80% investment requirement of “net assets” (which includes net assets plus any borrowings for investment purposes) discussed above may be changed by the Board without shareholder approval as long as shareholders are given 60 days notice of the change.

FUNDamentals™

Investment Grade and Below Investment Grade Securities

Investment grade securities include securities that are rated in one of the four highest rating categories as determined by a nationally recognized statistical rating organization, such as Standard & Poor’s, Fitch or Moody’s, or are unrated securities determined to be of comparable quality. Investment grade securities are rated (from highest to lowest quality) as AAA, AA, A or BBB by Standard & Poor’s and Fitch or as Aaa, Aa, A or Baa by Moody’s. Below investment grade securities include securities that are rated lower than investment grade securities and also may include securities that are unrated.

FUNDamentals™

Convertible Securities

Convertible securities, which include convertible bonds and convertible preferred stocks, can be exchanged for common stock at a specified rate. The common stock it converts to is called the “underlying” common stock.

Convertible securities typically:

n have higher income potential than the underlying common stock,

n are affected less by changes in the stock market than the underlying common stock, and

n have the potential to change in value if the value of the underlying common stock changes.

FUNDamentals™

Foreign Securities

Foreign securities include debt, equity or derivative securities which are determined to be “foreign” on the basis of an issuer’s domicile, its principal place of business, its primary stock exchange listing, the source of its revenues or other factors.

FUNDamentals™

Emerging Markets

Emerging markets comprise those countries whose economies are considered to be developing – or emerging from underdevelopment – and usually include most or all of Eastern Europe, the Middle East, Asia, Latin America and Africa. Emerging market countries may experience instability resulting from rapid social, political and economic development and their securities markets may be less developed and more thinly traded.

Principal Risks

Investment Strategy Risk – The Advisor uses the principal investment strategies and other investment strategies to seek to achieve the Fund’s investment objective. Investment decisions made by the Advisor in using these strategies may not produce the returns expected by the Advisor, 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 rise or 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, among other factors. In general, equity securities tend to have greater price volatility than debt securities.

Low and Below Investment Grade Securities Risk – Debt securities with the lowest investment grade rating (e.g., BBB by Standard & Poor’s or Fitch) or that are below investment grade (e.g., BB or below by Standard & Poor’s or Fitch) are more speculative than securities with higher ratings, and 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 on these securities than is the case for higher-rated securities. These securities typically pay a premium – a high 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, Standard & Poor’s 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.

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.

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

Liquidity Risk – Illiquid securities are securities that cannot be readily disposed of in the normal course of business. There is a risk that the Fund may not be able to sell such securities at the time it desires, or that it cannot sell such securities without adversely affecting their price.

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 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.

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.

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 and 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, these 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.

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 will affect the value of the Fund’s shares. Interest rate risk is generally greater for debt securities with longer maturities/durations.

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, and are thus subject to market risk. Because the value of a convertible security can be influenced by both interest rates and 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.

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), reference rates (such as LIBOR) or market indices (such as the S&P 500^® Index). Derivatives involve special risks and may result in losses. 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. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund’s potential inability to terminate or 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 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 may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative investments and strategies, see the SAI.

Reinvestment Risk – Income from the Fund’s debt securities portfolio will decline if and when the Fund invests the proceeds from matured, traded or called securities in securities with market interest rates that are below the current earnings rate of the Fund’s portfolio.

These are summaries of the principal risks associated with the principal investment strategies of the Fund. Additional risks are associated with other permissible investments of the Fund that are described in the SAI together with further information about these principal risks. There is no assurance that the Fund will achieve its investment objective.

The bar chart below shows you how the performance of the Fund’s Class A shares has varied from year to year. These returns do not reflect deductions of sales charges, if any, paid by investors and would be lower if they did.

FUNDamentals™

Fund Performance

Many factors can affect a mutual fund’s performance, including, for example:

n management of fund holdings,

n market conditions,

n fund expenses, and

n flows of investment dollars into and out of the fund.

The returns for the various share classes may vary based on differences in sales charges and expenses.

The table below shows the Fund’s Class A shares’ average annual total returns (i) before taxes, (ii) after taxes on distributions and (iii) after taxes on distributions and sale of Fund shares. The table also shows the average annual returns for the Fund’s Class B and Class C shares, but it does not show those classes’ after-tax returns, which will vary from those shown for the Fund’s Class A shares. The table compares the Fund’s returns for each period with those of the JPMorgan Global High Yield Index, an unmanaged index that is designed to mirror the investible universe of the US dollar global high yield corporate debt market, including domestic and international issues. The table also compares the Fund’s returns for each period with those of the Credit Suisse High Yield Index, an unmanaged broad-based index that tracks the performance of high yield bonds. The indices are not available for investment, and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing.

The fee table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Additional hypothetical fee and expense information relating to Class A, Class B and Class C shares of the Fund can be found in Hypothetical Fees and Expenses.

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:

Remember this is an example only. It is not necessarily representative of the Fund’s actual expenses in the past or future. Your actual costs could be higher or lower depending on the amount you invest and on the Fund’s actual expenses and performance.

Additional Investment Strategies and Policies

This section describes certain strategies and policies that the Fund may utilize in pursuit of its investment objective, and describes some additional factors and risks involved with investing in the Fund.

Changing the Fund’s Investment Objective and Policies

The Fund’s investment objective and certain of its investment policies can be changed without shareholder approval unless otherwise stated in this prospectus or the SAI. Shareholders vote on changes to other investment policies that are designated as fundamental in accordance with the requirements of the Investment Company Act of 1940 (the 1940 Act).

Holding Other Kinds of Investments

The Fund may hold investments that aren’t part of its principal investment strategies. These investments are described in the SAI. The Fund may choose not to invest in certain securities described in this prospectus and in the SAI, although it has the ability to do so.

Investing in Columbia Money Market Funds

The Fund may invest uninvested cash in shares of the registered or unregistered money market funds advised by the Advisor. The Advisor and its affiliates receive fees from these funds for providing advisory and other services in addition to the fees which they are entitled to receive from the Fund for services provided directly.

Portfolio Holdings Disclosure

A description of Columbia Funds’ policies and procedures with respect to the disclosure of Fund portfolio securities is available in the SAI. Each Columbia Fund discloses its portfolio holdings on the Columbia Funds’ website, www.columbiafunds.com, as described below. Once posted, the portfolio holdings information will remain available on the website until at least the date on which such Fund files a Form N-CSR or Form N-Q for the period that includes the date as of which the information is current.

The Fund’s complete portfolio holdings as of a fiscal quarter-end are disclosed approximately 60 calendar days after such quarter-end. The Fund’s largest 15 issuers as a percent of the Fund’s portfolio as of a month-end are disclosed approximately 15 calendar days after such month-end.

In addition, more current information concerning the Fund’s portfolio holdings as of specified dates may also be disclosed on the Columbia Funds’ website.

Investing Defensively

The Fund may from time to time take temporary defensive investment positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political or other conditions. The Fund may not achieve its investment objective while it is investing defensively.

Mailings to Households

In order to reduce shareholder expenses we may, if prior consent has been provided, mail only one copy of the Fund’s prospectus and each annual and semi-annual report to those addresses shared by two or more accounts. If you wish to receive individual copies of these documents, call 800.345.6611 or, if your shares are held through a financial intermediary, contact your intermediary directly.

Primary Service Providers

The Advisor, Distributor and Transfer Agent, all affiliates of Bank of America, currently provide key services to the Fund and the other Columbia Funds, including investment advisory, distribution, administration, shareholder servicing and transfer agency, and are paid for providing these services. These service relationships are described below.

The Advisor

The Advisor (which is also the Administrator) is located at 100 Federal Street, Boston, MA 02110, and serves as investment advisor to over 100 Columbia Funds mutual fund portfolios. As of June 30, 2007, the Advisor had assets under management of approximately $356.1 billion. The Advisor is a registered investment advisor and an indirect, wholly owned subsidiary of Bank of America. Its management experience covers all major asset classes, including equity securities, fixed income securities and money market instruments. In addition to serving as investment advisor to mutual funds, the Advisor acts as an investment manager for individuals, corporations, retirement plans, private investment companies and financial intermediaries.

Subject to oversight by the Board, the Advisor manages the day-to-day operations of the Fund, determining what securities and other investments the Fund should buy or sell and executing the Fund’s portfolio transactions. Although the Advisor is responsible for the investment management of the Fund, the Advisor may delegate certain of its duties to one or more investment sub-advisors. The Advisor may also use the research and other expertise of its affiliates and third parties in managing the Fund’s investments.

The Fund pays the Advisor a fee for its investment advisory services. The fee is calculated as a percentage of the average daily net assets of the Fund and is paid monthly. For the Fund’s most recent fiscal year, aggregate advisory fees paid to the Advisor by the Fund amounted to 0.60% of average daily net assets of the Fund.

A discussion regarding the basis for the Board’s approval of the Fund’s investment advisory agreement with the Advisor is available in the Fund’s semi-annual report to shareholders for the period ended November 30, 2006.

Sub-Advisor(s)

The Advisor may engage an investment sub-advisor or sub-advisors to make the day-to-day investment decisions for the Fund. The Advisor retains ultimate responsibility (subject to Board oversight) for overseeing any sub-advisor it engages and for evaluating the Fund’s needs and available sub-advisors’ skills and abilities on an ongoing basis. Based on its evaluations, the Advisor may at times recommend to the Board that the Fund change, add or terminate one or more sub-advisors; continue to retain a sub-advisor even though the sub-advisor’s ownership or corporate structure has changed; or materially change a sub-advisory agreement with a sub-advisor. Applicable law requires the Fund to obtain shareholder approval in order to act on most of these types of recommendations, even if the Board has approved the proposed action and believes that the action is in shareholders’ best interests. The Advisor and the Columbia Funds have applied for relief from the SEC to permit the Fund to act on many of the Advisor’s recommendations with approval only by the Board and not by Fund shareholders. The Advisor or the Fund would inform the Fund’s shareholders of any actions taken in reliance on this relief. Until the Advisor and the Fund obtain this relief, the Fund will continue to submit these matters to shareholders for their approval to the extent required by applicable law.

At present, the Advisor has not engaged any sub-advisor for the Fund.

Portfolio Managers

Information about the Advisor’s portfolio managers that are primarily responsible for overseeing the Fund’s investments is shown in the table below. The SAI provides more information about each portfolio manager’s compensation, other accounts managed by each portfolio manager and each portfolio manager’s ownership of securities in the Fund.

The Administrator

The Administrator is responsible for overseeing the administrative operations of the Fund, including the general supervision of the Fund’s operations, coordination of the Fund’s service providers, and the provision of office facilities and related clerical and administrative services. The Administrator does not currently receive any fees for the administrative services it provides to the Fund.

The Distributor

Shares of the Fund are distributed by the Distributor, which is located at One Financial Center, Boston, MA 02111. The Distributor is a registered broker/dealer and an indirect, wholly owned subsidiary of Bank of America. The Distributor and its affiliates may pay commissions, distribution and service fees and/or other compensation to entities for selling shares and providing services to investors.

The Transfer Agent

The Transfer Agent is a registered transfer agent and an indirect, wholly owned subsidiary of Bank of America. The Transfer Agent is located at One Financial Center, Boston, MA 02111, and its responsibilities include processing purchases, sales and exchanges, calculating and paying distributions, keeping shareholder records, preparing account statements and providing customer service. The Fund pays the Transfer Agent monthly fees on a per-account basis. Fees paid to the Transfer Agent include reimbursements for certain out-of-pocket expenses and sub-transfer agency fees paid by the Transfer Agent on the Fund’s behalf.

Other Roles and Relationships of Bank of America and its Affiliates – Certain Conflicts of Interest

As described in Management of the Fund – Primary Service Providers, the Advisor, Administrator, Distributor and Transfer Agent, all affiliates of Bank of America, provide various services to the Fund for which they are compensated. Bank of America and its affiliates also may provide other services to the Fund and be compensated for them.

The Advisor and its affiliates may provide investment advisory and other services to other clients and customers substantially similar to those provided to the Fund. These activities, and other financial services activities of Bank of America and its affiliates, may present actual and potential conflicts of interest and introduce certain investment constraints.

Bank of America is a major financial services company, engaged in a broad range of financial activities beyond the mutual fund-related activities of the Advisor, including, among others, commercial banking, investment banking, broker/dealer (sales and trading), asset management, insurance and other financial activities. These additional activities may involve multiple advisory, transactional, lending, financial and other interests in securities and other instruments, and in companies that issue securities and other instruments, which may be bought, sold or held by the Fund.

Conflicts of interest and limitations that could affect the Fund may arise from, for example, the following:

compensation and other benefits received by the Advisor and other Bank of America affiliates related to the management/administration of the Fund and the sale of its shares;

the allocation of, and competition for, investment opportunities among the Fund and other funds and accounts advised/managed by the Advisor and other Bank of America affiliates;

separate and potentially divergent management of the Fund and other funds and accounts advised/managed by the Advisor and other Bank of America affiliates;

regulatory and other investment restrictions on investment activities of the Advisor and other Bank of America affiliates and accounts advised/managed by them;

lending, investment banking and other relationships of Bank of America affiliates with companies and other entities in which the Fund invests; and

regulatory and other restrictions relating to the sharing of information between Bank of America and its affiliates, including the Advisor, and the Fund.

Bank of America and its affiliates also provide a variety of products and services that, in some manner, may use the Fund and other Columbia Funds as investment options. For example:

the Columbia Funds are available as investments in connection with brokerage and other securities products offered by Banc of America Investment Services, Inc., an affiliated retail broker/dealer of Bank of America;

the Columbia Funds are used as investments in connection with fiduciary, investment management and other accounts offered by U.S. Trust, Bank of America Private Wealth Management, as well as certain Columbia Funds structured as “funds of funds;” and

the Columbia Money Market Funds are offered as an investment option for a variety of cash “sweep” account programs offered by Bank of America and its affiliates.

The use of the Columbia Funds as investment options in connection with other products and services offered by Bank of America and its affiliates may introduce economic and other conflicts of interest of which you should be aware. These conflicts of interest are highlighted in sections of account documentation and other disclosure materials relating to these products and services, as well as in the SAI.

The Advisor and Bank of America have adopted various policies and procedures that are intended to identify, monitor and address conflicts of interest. However, there is no absolute assurance that these policies, procedures and disclosures will be effective.

Additional information about Bank of America and the types of conflicts of interest and other matters referenced above is set forth in the Investment Advisory and Other Services – Other Roles and Relationships of Bank of America and Affiliates – Certain Conflicts of Interest section of the SAI, which is identified by the LOGO icon. Investors in the Fund should carefully review these disclosures and consult with their financial advisor if they have any questions.

Certain Legal Matters

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) (Columbia) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the Distributor) (collectively, the Columbia Group) entered into an Assurance of Discontinuance with the New York Attorney General (NYAG) (the NYAG Settlement) and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission (SEC) (the SEC Order) on matters relating to mutual fund trading.

Under the terms of the SEC Order, the Columbia Group agreed, among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group’s applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce management fees for certain Columbia Funds (including the former Nations Funds) and other mutual funds collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above is being distributed in accordance with a distribution plan that was developed by an independent distribution consultant and approved by the SEC on April 6, 2007. Distributions under the distribution plan began in late June 2007.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the MDL). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court’s memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants’ motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds Trusts. As to Columbia and the Distributor, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA were not dismissed.

On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that certain conduct, including market timing, entitled Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the CDSC Lawsuit). The CDSC Lawsuit was removed to federal court in Massachusetts and transferred to the MDL.

On September 14, 2007, the plaintiffs and the Columbia defendants named in the MDL, including the Columbia Funds, entered into a stipulation of settlement with respect to all Columbia-related claims in the MDL described above, including the CDSC Lawsuit. The settlement is subject to court approval.

In 2004, the Columbia Funds’ adviser and distributor and certain affiliated entities and individuals were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. Certain Columbia Funds were named as nominal defendants. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment in favor of the defendants. The plaintiffs appealed to the United States Court of Appeals for the First Circuit on December 30, 2005. A stipulation and settlement agreement dated January 19, 2007 was filed in the First Circuit on February 14, 2007, with a joint stipulation of dismissal and motion for remand to obtain district court approval of the settlement. That joint motion was granted and the appeal was dismissed. On March 6, 2007, the case was remanded to the District Court. On September 18, 2007, the District Court approved the settlement, to be effective following the expiration of the appeal period. The funds’ adviser and/or its affiliates will be required, pursuant to the settlement, to make certain payments including plaintiffs’ attorneys’ fees and costs of notice to class members.

The Fund offers three classes of shares in this prospectus: Class A, Class B and Class C shares. The Fund may also offer other classes of shares through a separate prospectus. Each share class has its own investment eligibility criteria, cost structure and other features. The following summarizes the primary features of the Class A, Class B and Class C shares offered by this prospectus. Contact your financial advisor or Columbia Funds for more information about the Fund’s share classes and how to choose among them.

Sales charges, commissions and distribution and service fees (discussed in a separate sub-section below) compensate selling and/or servicing agents, and typically your financial advisor, for selling shares to you and for maintaining and servicing the shares held in your account. These charges, commissions and fees are intended to provide incentives for selling and/or servicing agents to provide these services.

You’ll pay a front-end sales charge when you buy Class A shares unless you qualify for a waiver of the sales charge or you buy the shares through reinvested distributions. See Choosing a Share Class – Reductions/Waivers of Sales Charges for more information.

Class A Shares – CDSC and Commissions

In some cases, you’ll pay a CDSC if you sell Class A shares that you bought without an initial sales charge.

If you bought Class A shares without an initial sales charge because your accounts aggregated $1 million to $50 million at the time of purchase, you will incur a 1.00% CDSC if you redeem those shares within one year of buying them.

Subsequent Class A share purchases that bring your aggregate account value to $1 million or more (but less than $50 million) will also be subject to a CDSC if you redeem them within one year of buying them.

The CDSC on Class A shares:

is applied to the net asset value at the time of your purchase or sale, whichever is lower, and

will not be applied to any shares you receive through reinvested distributions.

For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. When you place an order to sell your Class A shares, the Fund will first redeem any shares that aren’t subject to a CDSC followed by those you have held the longest. The CDSC on Class A shares does not apply to retirement plans buying through a fee-based program.

The Distributor may pay your selling and/or servicing agent an up-front commission of up to 4.25% of the offering price per share when you buy Class A shares. The Distributor funds the commission through the applicable sales charge.

The Distributor may also pay your selling and/or servicing agent a cumulative commission when you buy $1 million or more of Class A shares, according to the following schedule:

Class A Shares – Commission Schedule


Purchase Amount		Commission Level (as a % of net asset value per share)
$1 million – $2,999,999		1.00%
$3 million – $49,999,999		0.50%
$50 million or more		0.25%

Class B and Class C Shares – Sales Charges

You don’t pay a front-end sales charge when you buy Class B or Class C shares, but you may pay a CDSC when you sell Class B or Class C shares.

The CDSC on Class B and Class C shares:

is applied to the net asset value at the time of your purchase or sale, whichever is lower,

will not be applied to any shares you receive through reinvested distributions, and

generally declines each year until there is no sales charge for selling shares.

For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which your purchase was made. When you place an order to sell your Class B or Class C shares, the Fund will first redeem any shares that aren’t subject to a CDSC followed by those you have held the longest.

Class B Shares – CDSC and Commissions

You’ll pay a CDSC when you sell Class B shares unless you qualify for a waiver of the CDSC or the shares you’re selling were bought through reinvested distributions. See Choosing a Share Class – Reductions/Waivers of Sales Charges for details. The CDSC you pay on Class B shares depends on how long you’ve held your shares:

Class B Shares – CDSC Schedule


Number of Years Class B Shares Held		Applicable CDSC
One		5.00%
Two		4.00%
Three		3.00%
Four		3.00%
Five		2.00%
Six		1.00%
Seven		none
Eight		none
Nine		Class A Shares

The Distributor pays an up-front commission directly to your selling and/or servicing agent of up to 5.00% of the net asset value per share when you buy Class B shares. The Distributor seeks to recover this commission through distribution fees it receives under the Fund’s distribution plan and any applicable CDSC when you sell your shares. See Choosing a Share Class – Distribution and Service Fees for details.

Class B shares automatically convert to Class A shares after you’ve owned them for eight years. This conversion feature allows you to benefit from the lower operating costs of Class A shares, which can help increase your total returns from an investment in the Fund.

The following rules apply to the conversion of Class B shares to Class A shares:

Class B shares are converted on or about the 15th day of the month that next occurs after they become eligible for conversion.

Any shares you received from reinvested distributions on these shares generally will convert to Class A shares at the same time.

You’ll receive the same dollar value of Class A shares as the Class B shares that were converted.

Class B shares that you received from an exchange of Class B shares of another Columbia Fund will convert based on the day you bought the original shares.

No sales charge or other charges apply, and conversions are free from federal income tax.

Class C Shares – CDSC and Commissions

You’ll pay a CDSC of 1.00% when you sell Class C shares within one year of buying them unless you qualify for a waiver of the CDSC or the shares you’re selling were bought through reinvested distributions. See Choosing a Share Class – Reductions/Waivers of Sales Charges for details.

The Distributor pays an up-front commission directly to your selling and/or servicing agent of up to 1.00% of the net asset value per share when you buy Class C shares. The Distributor seeks to recover this commission through distribution fees it receives under the Fund’s distribution plan and any applicable CDSC applied when you sell your shares. See Choosing a Share Class – Distribution and Service Fees for details.

Reductions/Waivers of Sales Charges

Front-End Sales Charge Reductions

There are two ways in which you may be able to reduce the front-end sales charge that you may pay when you buy Class A shares of the Fund. These types of sales charge reductions are also referred to as breakpoint discounts.

First, through the right of accumulation, you may combine the value of eligible accounts (regardless of class) maintained by you and your immediate family to reach a breakpoint discount level and apply a lower sales charge to your purchase. To calculate the combined value of your accounts, the Fund will use the current public offering price per share.

Second, by making a statement of intent to purchase additional shares, you may pay a lower sales charge on all purchases of Class A shares made within 13 months of the date of your statement of intent. Your statement of intent must state the aggregate amount of purchases you intend to make in that 13-month period, which must be at least $50,000. If you do not complete the purchases described in your statement of intent within 13 months, you will be charged the applicable sales charge on the amount you have invested to that date. To calculate the total value of the purchases you’ve made under a statement of intent, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account.

To obtain a breakpoint discount, you must notify your financial advisor in writing at the time you buy your shares of each eligible account maintained by you and/or your immediate family. It is the responsibility of you and your financial advisor to ensure that you receive discounts for which you are eligible; the Fund is not responsible for a financial advisor’s failure to apply the eligible discount to your account. You may be asked by your financial advisor for account statements or other records to verify your discount eligibility, including, when applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family.

FUNDamentals™

Your “Immediate Family” and

Account Value Aggregation

For purposes of reaching the Class B shares investment limits described in Choosing a Share Class – Comparison of the Share Classes and obtaining a Class A shares breakpoint discount, the value of your account will be deemed to include the value of all eligible accounts that are held by your “immediate family,” which includes your spouse (or legal equivalent under state law), parent, step-parent, legal guardian, child, step-child, father-in-law and mother-in-law. Remember that in order to obtain a breakpoint discount, you must notify your financial advisor in writing at the time you buy your shares of each eligible account maintained by you and/or your immediate family. Group plan accounts are valued at the plan level.

Eligible Accounts

The types of accounts that are eligible for the account value aggregation purposes described above are:

individual accounts,

joint accounts,

certain IRA accounts,

certain health savings accounts,

certain trust accounts, and

Uniform Gifts to Minors Act (UGMA)/Uniform Transfers to Minors Act (UTMA) accounts.

Eligible accounts include those registered in the name of the broker/dealer or other financial intermediary through which you own shares of the Columbia Funds.

Eligible accounts do not include Class R or Class Z share accounts or accounts holding institutional share classes of the Columbia Money Market Funds (Capital Class shares, Liquidity Class shares, Adviser Class shares, Investor Class shares, Trust Class shares, Institutional Class shares and Marsico shares). Certain share classes are not offered by this prospectus.

Front-End Sales Charge Waivers

Certain investors may buy Class A shares of the Fund at net asset value, which excludes any front-end sales charge that would otherwise apply. These investors include affiliates of the Fund, broker/dealers, investors in wrap fee programs, investors through fee-based advisors, certain retirement plans, certain health savings accounts, certain shareholders of funds that were reorganized into Columbia Funds, investors using the proceeds of sales of Fund shares or of certain Bank of America trust or similar accounts, as well as insurance company separate accounts purchasing for the benefit of group retirement plans. Restrictions may apply to certain accounts and certain transactions.

CDSC Waivers

You may be able to avoid an otherwise applicable CDSC when you sell Class A, Class B or Class C shares of the Fund. This could happen because of the way in which you originally invested in the Fund, because of your relationship with the Columbia Funds or for other reasons.

Generally, a CDSC that would otherwise be applied may be waived for certain sales, including sales made under the Systematic Withdrawal Plan or in connection with the death or post-purchase disability of a shareholder; certain medical expenses; charitable gifts; involuntary sales; and agreements by selling and/or servicing agents to waive or return their commissions. Restrictions may apply to certain accounts and certain transactions.

The Fund may change or cancel these terms at any time. Any change or cancellation applies only to future purchases.

For more information about the sales charge reductions and waivers described here, consult the SAI.

Distribution and Service Fees

Pursuant to Rule 12b-1 under the 1940 Act, the Board has approved, and the Fund has adopted, distribution and shareholder servicing plans which set the distribution and service fees that are periodically deducted from the Fund’s assets. These fees are calculated daily, may vary by share class and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors. Because the fees are paid out of the Fund’s assets on an ongoing basis, they will increase the cost of your investment over time.

The table below shows the maximum annual distribution and service fees (as an annual % of average daily net assets) and the combined amount of such fees applicable to each share class:

Distribution and Service Fees


	Distribution Fee		Service Fee	Combined Total
Class A	—		0.25%	0.25%
Class B	0.75%		0.25%	1.00%
Class C	0.75%	^(a)	0.25%	1.00%

^(a)	The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that it does not exceed 0.60% annually.

The Fund will pay these fees to the Distributor and/or to eligible selling and/or servicing agents for as long as the distribution and/or shareholder servicing plans continue. The Fund may reduce or discontinue payments at any time. Your selling and/or servicing agent may also charge you other fees for providing services to your account, which may be different from those described here.

Financial Intermediary Compensation

The Distributor and other Bank of America affiliates may make payments, from their own resources, to certain financial intermediaries, including other Bank of America affiliates, for marketing/sales support services relating to the Columbia Funds. These payments are generally based upon one or more of the following factors: average net assets of the Columbia Funds sold by the Distributor attributable to that intermediary, gross sales of the Columbia Funds distributed by the Distributor attributable to that intermediary, reimbursement of ticket charges (fees that an intermediary firm charges its representatives for effecting transactions in Fund shares) or a negotiated lump sum payment. While the financial arrangements may vary for each intermediary, the support payments to any one intermediary are generally between 0.05% and 0.35% (and 0.03% and 0.12% with regard to the Columbia Money Market Funds) on an annual basis for payments based on average net assets of the Fund attributable to the intermediary, and between 0.10% and 0.25% on an annual basis for firms receiving a payment based on gross sales of the Columbia Funds (other than the Columbia Money Market Funds) attributable to the intermediary.

The Distributor and other Bank of America affiliates may make payments in larger amounts or on a basis other than those described above when dealing with other affiliates of Bank of America. Such increased payments to the other Bank of America affiliate may enable the other Bank of America affiliate to offset credits that it may provide to customers in order to avoid having such customers pay fees to multiple Bank of America entities in connection with the customers’ investments in the Fund.

These payments for shareholder servicing support vary by financial intermediary but generally are not expected, with certain limited exceptions, to exceed 0.35% of the average aggregate value of the Fund’s shares in any intermediary’s program on an annual basis for those classes of shares that pay a service fee pursuant to a plan under Rule 12b-1 under the 1940 Act, and 0.45% of the average aggregate value of the Fund’s shares in any intermediary’s program on an annual basis for those classes of shares that do not pay a service fee pursuant to a plan under Rule 12b-1 under the 1940 Act.

The Board has authorized the Fund to reimburse the Transfer Agent for amounts paid to financial intermediaries that maintain assets in omnibus accounts, subject to an annual cap of 0.11% of the average aggregate value of the Fund’s shares maintained in such accounts. The amounts in excess of that reimbursed by the Fund are borne by the Distributor or other Bank of America affiliates. The Distributor and other Bank of America affiliates may make other payments or allow promotional incentives to broker/dealers to the extent permitted by SEC and Financial Industry Regulatory Authority (FINRA) rules and by other applicable laws and regulations.

Amounts paid by the Distributor and other Bank of America affiliates are paid out of the Distributor’s and other Bank of America affiliates’ own resources and do not increase the amount paid by you or the Fund. You can find further details about the payments made by the Distributor and other Bank of America affiliates and the services provided by financial intermediaries as well as a list of the intermediaries to which the Distributor and other Bank of America affiliates have agreed to make marketing support payments in the SAI. Your financial intermediary may charge you fees and commissions in addition to those described in this prospectus. You should consult with your financial intermediary and review carefully any disclosure your financial intermediary provides regarding its services and compensation. Depending on the financial arrangement in place at any particular time, a financial intermediary and its financial consultants may have a financial incentive for recommending the Fund or a particular share class over others. See Management of the Fund – Other Roles and Relationships of Bank of America and its Affiliates – Certain Conflicts of Interest for more information.

Share Price Determination

The price you pay or receive when you buy, sell or exchange shares is the Fund’s next determined net asset value (or NAV) per share for a given share class. The Fund calculates the net asset value per share for each class of the Fund at the end of each business day.


FUNDamentals™
NAV Calculation
Each of the Fund’s share classes calculates its NAV as follows:
		(Value of assets of the share class)
NAV	=	– (Liabilities of the share class)
		Number of outstanding shares of the class

The value of the Fund’s shares is based on the total market value of all of the securities and other assets that it holds as of a specified time. The prices reported on stock exchanges and other securities markets around the world are usually used to value securities in the Fund. The Fund uses the amortized cost method, which approximates market value, to value short-term investments maturing in 60 days or less.

If a market price isn’t readily available, the Fund will determine the price of the security held by the Fund based on the Advisor’s determination of the security’s fair value. A market price is considered not readily available if, among other circumstances, the most recent reported price is deemed unreliable. In addition, the Fund may use fair valuation to price securities that trade on a foreign exchange when a significant event has occurred after the foreign exchange closes but before the time at which the Fund’s share price is calculated. Foreign exchanges typically close before the time at which Fund share prices are calculated, and may be closed altogether on some days when the Fund is open. Such significant events affecting a foreign security may include, but are not limited to: (1) those impacting a single issuer; (2) governmental action that affects securities in one sector or country; (3) natural disasters or armed conflicts affecting a country or region; or (4) significant domestic or foreign market fluctuations. The Fund uses various criteria, including an evaluation of U.S. market moves after the close

of foreign markets, in determining whether a security’s market price is readily available and, if not, the fair value of the security.

Fair valuation may have the effect of reducing stale pricing arbitrage opportunities presented by the pricing of Fund shares. However, when the Fund uses fair valuation to price securities, it may value those securities higher or lower than another mutual fund. Also, the use of fair valuation may cause the Fund’s performance to diverge to a greater degree from the performance of various benchmarks used to compare the Fund’s performance because benchmarks generally do not use fair valuation techniques. Because of the judgment involved in fair valuation decisions, there can be no assurance that the value ascribed to a particular security is accurate. The Fund has retained an independent fair valuation pricing service to assist in the fair valuation process for foreign securities. International markets are sometimes open on days when U.S. markets are closed, which means that the value of foreign securities owned by the Fund could change on days when Fund shares cannot be bought or sold.

Transaction Rules and Policies

Remember that sales charges may apply to your transactions. You should also ask your selling and/or servicing agent about its rules, fees and policies for buying, selling and exchanging shares, which may be different from those described here, and about its related programs or services.

Also remember that the Fund may refuse any order to buy or exchange shares. If this happens, we’ll return any money we’ve received, but no interest will be paid on that money.

Order Processing

Orders to buy, sell or exchange shares are processed on business days. Orders can be delivered by mail, by telephone or online. Orders received in “good form” by the Transfer Agent or your selling and/or servicing agent before the end of a business day will receive that day’s net asset value per share. Orders received after the end of a business day will receive the next business day’s net asset value per share. The business day that applies to your order is also called a trade date.

FUNDamentals™

Business Days

A business day is any day that the New York Stock Exchange (NYSE) is open. A business day ends at the close of regular trading on the NYSE, usually at 4:00 p.m. Eastern time. If the NYSE closes early, the business day ends as of the time the NYSE closes. On holidays and other days when the NYSE is closed, the Fund’s net asset value is not calculated and the Fund does not accept buy or sell orders. However, the value of the Fund’s assets may still be affected on such days to the extent that the Fund holds foreign securities that trade on days that foreign markets are open.

“Good Form”

An order is in “good form” if the Transfer Agent or your selling and/or servicing agent has all of the information and documentation it deems necessary to effect your order. For example, when you sell shares by letter of instruction, “good form” means that your letter has (i) complete instructions and the signatures of all account owners, (ii) a Medallion signature guarantee for amounts equal to or greater than

$100,000 and (iii) any other required documents completed and attached. For the documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, call 800.345.6611.

Medallion Signature Guarantees

Qualified customers can obtain a Medallion signature guarantee from any financial institution – including commercial banks such as Bank of America, credit unions and broker/dealers – that participates in one of the three Medallion signature guarantee programs recognized by the SEC. These Medallion signature guarantee programs are the Securities Transfer Agents Medallion Program (STAMP), the Stock Exchanges Medallion Program (SEMP) and the New York Stock Exchange Medallion Signature Program (MSP).

Written Transactions

Once you have an account, you can communicate written buy, sell and exchange orders to the Transfer Agent at the following address: Columbia Funds, c/o Columbia Management Services, Inc., P.O. Box 8081, Boston, MA 02266-8081.

Telephone Transactions

Once you have an account, you can place orders to buy, sell or exchange by telephone depending on how you complete the telephone authorization section of your account application. To place orders by telephone, call 800.422.3737. Have your account number and taxpayer identification number (TIN) available when calling.

You can sell up to an aggregate of $100,000 of shares via the telephone in any 30-day period if you qualify for telephone orders.

Telephone orders may not be as secure as written orders. Columbia Funds will take reasonable steps to confirm that telephone instructions are genuine. For example, we require proof of your identification before we will act on instructions received by telephone and may record telephone conversations. However, the Fund and its agents will not be responsible for any losses, costs or expenses resulting from an unauthorized telephone instruction when reasonable steps have been taken to confirm that telephone instructions are genuine. Telephone orders may be difficult to complete during periods of significant economic or market change or business interruption.

Online Transactions

Once you have an account, contact Columbia Funds at 800.345.6611 for more information on account trading restrictions and the special sign-up procedures required for online transactions. The Transfer Agent has procedures in place to authenticate electronic orders you deliver through the internet. You will be required to accept the terms of an online agreement and establish and utilize a password in order to access online account services.

You can sell up to an aggregate of $100,000 of shares through the internet in any 30-day period if you qualify for internet orders.

Customer Identification Program

Federal law requires the Fund to obtain and record specific personal information to verify your identity when you open an account. This information may include your name, address, date of birth (for individuals), and taxpayer or other government issued identification. If you fail to provide the requested information, the Fund may need to delay the date of your purchase or may be unable to open your account, which may result in a return of your investment monies. In addition, if the Fund is unable to verify your identity after your account is open, the Fund reserves the right to close your account or take other steps as deemed reasonable. The Fund shall not be held liable for any loss resulting from any purchase delay, application rejection or account closure due to a failure to provide proper identifying information.

Small Account Policy – Accounts Below $250

Columbia Funds generally will automatically sell your shares if the value of your account (treating each account of the Fund you own separately from any other account of the Fund you may own) falls below $250. If your shares are sold, the Transfer Agent will remit the sale proceeds to you. Any otherwise applicable CDSC will not be imposed on such automatic sale of your shares. The Transfer Agent will send you written notification in advance of any automatic sale, which will provide details on how you may avoid such automatic sale. Generally, you may avoid such automatic sale by raising your account balance, consolidating your accounts through an exchange of shares of another Columbia Fund in which you hold shares, or setting up a Systematic Investment

Plan. Contact the Transfer Agent, review our website at www.columbiafunds.com, call 800.345.6611 or contact your financial advisor for more information. The automatic sale of shares of accounts valued at less than $250 is expected to take place in the second quarter of each calendar year.

Columbia Funds may also sell your shares if a financial intermediary tells us to sell your shares pursuant to arrangements made with you, and under certain other circumstances allowed under the 1940 Act.

Small Account Policy – Minimum Balance Fee

If the value of your account (treating each account of the Fund you own separately from any other account of the Fund you may own) falls below the minimum initial investment requirement applicable to you, your account generally will be subject to a $20 annual fee. This fee will be assessed through the automatic sale of shares in your account. Any otherwise applicable CDSC will not be imposed on such automatic sale of your shares. The Transfer Agent will reduce the expenses paid by the Fund by any amounts it collects from the assessment of this fee. For Funds that do not have transfer agency expenses against which to offset the amount collected through assessment of this fee, the fee will be paid directly to the Fund. The Transfer Agent will send you written notification in advance of assessing any fee, which will provide details on how you can avoid the imposition of such fee. Generally, you may avoid the imposition of such fee by raising your account balance, consolidating your accounts through an exchange of shares of another Columbia Fund in which you hold shares, or setting up a Systematic Investment Plan. Contact the Transfer Agent, review our website at www.columbiafunds.com, call 800.345.6611 or contact your financial advisor for more information.

Columbia Funds reserves the right to change the minimum investment requirements for any Fund. We also reserve the right to lower the account size trigger point for the minimum balance fee in any year or for any class of shares when we believe it is appropriate to do so in light of declines in the market value of Fund shares, sales loads applicable to a particular class of shares, or for other reasons.

Exceptions to the Small Account Policy

The automatic sale of shares of accounts under $250 and the annual minimum balance fee described previously do not apply to shareholders of Class R shares or shareholders holding their shares through broker/dealer networked accounts; wrap fee and omnibus accounts; accounts with active Systematic Investment Plans or payroll deduction plans; accounts that were created by the automatic conversion of Class B shares to Class A shares or Class G shares to Class T shares; and certain qualified retirement plans and health savings accounts. The automatic sale of shares of accounts under $250 does not apply to individual retirement plans.

Cash Flows

The timing and magnitude of cash inflows from investors buying Fund shares could prevent the Fund from always being fully invested. Conversely, the timing and magnitude of cash outflows to investors selling Fund shares could require large ready reserves of uninvested cash to meet shareholder redemptions. Either situation could adversely impact the Fund’s performance.

Excessive Trading Practices

Right to Reject or Restrict Share Transaction Orders – The Fund is intended for investors with long-term investment purposes and is not intended as a vehicle for frequent trading activity (market timing) that is excessive. Investors should transact in Fund shares primarily for investment purposes. The Board has adopted excessive trading policies and procedures that are designed to deter excessive trading by investors (the Excessive Trading Policies and Procedures). The Fund discourages and does not accommodate excessive trading.

The Fund reserves the right to reject, without any prior notice, any buy or exchange order for any reason, and will not be liable for any loss resulting from rejected orders. For example, the Fund may in its discretion restrict, reject or cancel a buy or exchange order even if the transaction is not subject to the specific exchange limitation described below if the Fund or its agents determine that accepting the order could interfere with efficient management of the Fund’s portfolio or is otherwise contrary to the Fund’s best interests. The Excessive Trading Policies and Procedures apply equally

to buy or exchange transactions communicated directly to the Transfer Agent and to those received by selling and/or servicing agents.

Specific Buying and Exchanging Limitations – If the Fund detects that an investor has made two “material round trips” in any 28-day period, it will generally reject the investor’s future buy orders, including exchange buy orders, involving any Columbia Fund.

For these purposes, a “round trip” is a purchase or exchange into the Fund followed by a sale or exchange out of the Fund. A “material” round trip is one that is deemed by the Fund to be material in terms of its amount or its potential detrimental impact on the Fund. Independent of this limit, the Fund may, in its discretion, reject future buy orders by any person, group or account that appears to have engaged in any type of excessive trading activity.

These limits generally will not apply to automated transactions or transactions by registered investment companies that invest in the Fund using a “fund of funds” structure. They may be modified or rescinded for accounts held by certain retirement plans to conform to plan limits, for considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs. Accounts known to be under common ownership or control generally will be counted together, but accounts maintained or managed by a common intermediary generally will not be considered to be under common ownership or control. The Fund retains the right to modify these restrictions at any time without prior notice to shareholders.

Limitations on the Ability to Detect and Prevent Excessive Trading Practices – The Fund takes various steps designed to detect and prevent excessive trading, including daily review of available shareholder transaction information. However, the Fund receives buy, sell and exchange orders through financial intermediaries, and cannot always know or reasonably detect excessive trading that may be facilitated by financial intermediaries or by the use of the omnibus account arrangements they offer. Omnibus account arrangements are common forms of holding shares of mutual funds, particularly among certain financial intermediaries such as broker/dealers, retirement plans and variable insurance products. These arrangements often permit financial intermediaries to

aggregate their clients’ transactions and accounts, and in these circumstances, the identity of the shareholders is often not known.

Some financial intermediaries apply their own restrictions or policies to underlying investor accounts, which may be more or less restrictive than those described here. This may impact the Fund’s ability to curtail excessive trading, even where it is identified. For these and other reasons, it is possible that excessive trading may occur despite the Fund’s efforts to detect and prevent it.

Although these restrictions and policies involve judgments that are inherently subjective and may involve some selectivity in their application, the Fund seeks to act in a manner that it believes is consistent with the best interests of shareholders in making any such judgments.

Risks of Excessive Trading – Excessive trading creates certain risks to the Fund’s long-term shareholders and may create the following adverse effects:

negative impact on the Fund’s performance;

potential dilution of the value of the Fund’s shares;

interference with the efficient management of the Fund’s portfolio, such as the need to maintain undesirably large cash positions, the need to use its line of credit or the need to buy or sell securities it otherwise would not have bought or sold;

losses on the sale of investments resulting from the need to sell securities at less favorable prices;

increased taxable gains to the Fund’s remaining shareholders resulting from the need to sell securities to meet sell orders; and

increased brokerage and administrative costs.

certain circumstances to reflect what the Fund believes to be the fair value of those securities as of its valuation time. To the extent the adjustments don’t work fully, investors engaging in price arbitrage may cause dilution in the value of the Fund’s shares held by other shareholders.

Similarly, to the extent that the Fund invests significantly in thinly traded high yield bonds (junk bonds) or equity securities of small-capitalization companies, because these securities are often traded infrequently, investors may seek to trade their shares in an effort to benefit from their understanding of the value of these securities. This is also a type of price arbitrage. Any such frequent trading strategies may interfere with efficient management of the Fund’s portfolio to a greater degree than would be the case for mutual funds that invest in highly liquid securities, in part because the Fund may have difficulty selling those portfolio securities at advantageous times or prices to satisfy large and/or frequent sell orders. Any successful price arbitrage may also cause dilution in the value of Fund shares held by other shareholders.

Opening an Account and Placing Orders

Columbia Funds encourages you to consult with a financial advisor who can help you with your investment decisions and who can help you open an account. Once you have an account, you can buy, sell and exchange shares by contacting your financial advisor who will send your order to the Transfer Agent or your selling and/or servicing agent. As described in Buying, Selling and Exchanging Shares – Transaction Rules and Policies, once you have an account you can also communicate your orders directly to the Transfer Agent by mail, by telephone or online.

Buying Shares

Eligible Investors

Class A, Class B and Class C shares are available to the general public for investment. Once you have opened an account, you can buy Class A, Class B and Class C shares in a lump sum, through our Systematic Investment Plan, by dividend diversification, by wire or by electronic funds transfer.

Minimum Initial Investments

The minimum initial investment for Class A, Class B and Class C shares is $2,500 for regular accounts and $1,000 for individual retirement plans (including traditional IRAs, Roth IRAs and Coverdell Education Savings Accounts) and non-omnibus group retirement plans. For investors establishing a Systematic Investment Plan, the minimum initial investment is $50. There is no minimum initial investment for Class A, Class B or Class C shares bought through omnibus accounts, wrap accounts or health savings accounts, although your selling and/or servicing agent may impose its own investment minimum. For group retirement plans, the minimum initial investment and minimum additional investment are determined based on the plan’s investment rather than that of its individual participants.

Minimum Additional Investments

There is no minimum additional investment for Class A, Class B or Class C shares.

Systematic Investment Plan

The Systematic Investment Plan allows you to make regular purchases in amounts of $50 or more via automatic transfers

from your bank account to the Fund on a monthly, quarterly or semi-annual basis. Contact the Transfer Agent or your financial advisor to set up the plan.

Dividend Diversification

Generally, you may automatically invest distributions made by another Columbia Fund into the same class of shares (and in some cases certain other classes of shares) of the Fund at no additional sales charge. A sales charge may apply when you invest distributions made by a Columbia Fund that were not assessed a sales charge at the time of your initial purchase. Call Columbia Funds at 800.345.6611 for details.

Wire Purchases

You may buy Class A, Class B or Class C shares of the Fund by wiring money from your bank account to your Fund account by calling the Transfer Agent at 800.422.3737.

Electronic Funds Transfer

You may buy Class A, Class B or Class C shares of the Fund by electronically transferring money from your bank account to your Fund account by calling the Transfer Agent at 800.422.3737. An electronic funds transfer may take up to three business days to settle and be considered in “good form.” You must set up this feature by contacting the Transfer Agent prior to your request.

Other Purchase Rules You Should Know

Once the Transfer Agent or your selling and/or servicing agent receives your buy order in “good form,” your purchase will be made at the next calculated public offering price per share, which is the net asset value per share plus any sales charge that applies.

You generally buy Class A shares at the public offering price per share because purchases of Class A shares are generally subject to a front-end sales charge.

You buy Class B and Class C shares at net asset value per share because no front-end sales charge applies to purchases of these share classes.

The Fund reserves the right to cancel your order if it doesn’t receive payment within three business days of receiving your buy order. The Fund will return any payment received for orders that have been cancelled, but no interest will be paid on that money.

Selling and/or servicing agents are responsible for sending your buy orders to the Transfer Agent and ensuring that we receive your money on time.

Shares bought are recorded on the books of the Fund. The Fund doesn’t issue certificates.

Selling Shares

When you sell your shares, the Fund is effectively buying them back from you. This is called a redemption.

Wire Redemptions

You may request that your Class A, Class B or Class C shares sale proceeds be wired to your bank account by calling the Transfer Agent at 800.422.3737. You must set up this feature prior to your request. For shares sold by Fedwire, there is generally a fee of $7.50. The receiving bank may charge an additional fee. The Transfer Agent may waive the fee for certain accounts.

Electronic Funds Transfer

You may sell Class A, Class B or Class C shares of the Fund and request that the proceeds be electronically transferred to your bank account by calling the Transfer Agent at 800.422.3737. It may take up to three business days for the sale proceeds to be received by your bank. You must set up this feature by contacting the Transfer Agent prior to your request.

Systematic Withdrawal Plan

The Systematic Withdrawal Plan lets you withdraw funds from your Class A, Class B and/or Class C shares account any day of the month on a monthly, quarterly or semi-annual basis. Contact the Transfer Agent or your financial advisor to set up the plan. Your account balance generally must be at least $5,000 to set up the plan, but certain fee-based and wrap accounts are not subject to this requirement. If you set up the plan after you’ve opened your account, your signature must be Medallion guaranteed.

before sending the balance to you. You can cancel the plan by giving Columbia Funds 30 days notice in writing or by calling the Transfer Agent at 800.422.3737. It’s important to remember that if you withdraw more than your investment in the Fund is earning, you’ll eventually use up your original investment.

In-Kind Distributions

The Fund reserves the right to honor sell orders with in-kind distributions of portfolio securities instead of cash. In the event the Fund makes such an in-kind distribution, you may incur the brokerage and transaction costs associated with converting the portfolio securities you receive into cash. Also, the portfolio securities you receive may increase or decrease in value before you convert them into cash.

Other Redemption Rules You Should Know

Once the Transfer Agent or your selling and/or servicing agent receives your sell order in “good form,” your shares will be sold at the next calculated public offering price per share, which is the net asset value per share plus any sales charge that applies. Any applicable CDSC will be deducted from the amount you’re selling and the balance will be remitted to you.

If you sell your shares directly through Columbia Funds, we will normally send the sale proceeds by mail or electronically transfer them to your bank account within three business days after the Transfer Agent or your selling and/or servicing agent receives your order in “good form.”

If you sell your shares through a selling agent, Columbia Funds will normally send the sale proceeds by Fedwire within three business days after the Transfer Agent or your selling and/or servicing agent receives your order in “good form.”

If you paid for your shares by check, Columbia Funds will hold the sale proceeds when you sell those shares for up to 10 days after the trade date of the purchase.

No interest will be paid on uncashed redemption checks.

Columbia Funds can delay payment of the sale proceeds for up to seven days and may suspend redemptions and/or postpone payment of redemption proceeds when the NYSE is closed or during emergency circumstances as determined by the SEC.

Other restrictions may apply to retirement accounts. For information about these restrictions, contact your retirement plan administrator.

Also keep in mind Columbia Funds’ Small Account Policy, which is described above in Buying, Selling and Exchanging Shares – Transaction Rules and Policies.

Exchanging Shares

You can generally sell shares of the Fund to buy shares of another Columbia Fund, in what is called an exchange. You should read the prospectus of, and make sure you understand the investment objective and principal investment strategies of, the Columbia Fund into which you are exchanging.

Systematic Exchanges

You may buy Class A, Class B and/or Class C shares of the Fund by exchanging $100 or more each month from another Columbia Fund for shares of the same class of the Fund at no additional cost. Contact the Transfer Agent or your financial advisor to set up the plan. If you set up your plan to exchange more than $100,000 each month, you must have your signature Medallion guaranteed.

Exchanges will continue as long as your balance is sufficient to complete the systematic monthly transfers, subject to Columbia Funds’ Small Account Policy described above in Buying, Selling and Exchanging Shares – Transaction Rules and Policies. You may terminate the program or change the amount you would like to exchange (subject to the $100 minimum) by calling Columbia Funds at 800.345.6611. A sales charge may apply when you exchange shares of a Columbia Fund that were not assessed a sales charge at the time of your initial purchase.

The rules described below for making exchanges apply to systematic exchanges.

Class Z Shares Exchange Privilege

Certain shareholders invested in a class of shares other than Class Z may become eligible to be invested in Class Z shares. Upon a determination of such eligibility, any such shareholders will be eligible to exchange their shares for Class Z shares. No sales charges or other charges will apply to such an exchange. Investors should contact their selling and/or servicing agents to learn more about the details of the Class Z shares exchange privilege.

Other Exchange Rules You Should Know

Exchanges are made at net asset value.

You can generally make exchanges between like share classes of any Columbia Fund. Some exceptions apply.

A sales charge may apply when you exchange shares of a Columbia Fund that were not assessed a sales charge at the time of your initial purchase.

If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange of those shares. Any CDSC will be deducted when you sell the shares you received from the exchange. The CDSC imposed at that time will be based on the period that begins when you bought shares of the original Columbia Fund and ends when you sell the shares of the Columbia Fund you received from the exchange. The applicable CDSC will be the CDSC of the original Columbia Fund.

The rules for buying shares of a Columbia Fund apply to exchanges into that Fund.

You may make exchanges only into a Columbia Fund that is legally offered and sold in your state of residence.

You generally may make an exchange only into a Columbia Fund that is accepting investments.

The Fund may change or cancel your right to make an exchange by giving the amount of notice required by regulatory authorities (generally 60 days for a material change or cancellation).

Unless your account is part of a tax-advantaged retirement plan, an exchange is a taxable event, and you may realize a gain or loss for tax purposes.

Distributions to Shareholders

A mutual fund can make money two ways:

It can earn income on its investments. Examples of fund income are interest paid on money market instruments and bonds, and dividends paid on common stocks.

A mutual fund can also have capital gains if the value of its investments increases. While a fund continues to hold an investment, any gain is unrealized. If the fund sells an investment, it generally will realize a capital gain if it sells that investment for a higher price than it originally paid. Capital gains are either short-term or long-term, depending on whether the fund holds the securities for one year or less (short-term gains) or more than one year (long-term gains).

FUNDamentals ™

Distributions

Mutual funds make payments of fund earnings to shareholders, distributing them among all shareholders of the fund. As a shareholder, you are entitled to your portion of a fund’s distributed income, including capital gains.

Reinvesting your distributions buys you more shares of a fund – which lets you take advantage of the potential for compound growth. Putting the money you earn back into your investment means it, in turn, may earn even more money. Over time, the power of compounding has the potential to significantly increase the value of your investment. There is no assurance, however, that you’ll earn more money if you reinvest your distributions rather than receive them in cash.

The Fund intends to pay out, in the form of distributions to shareholders, a sufficient amount of its net income (interest and dividends less expenses) and net capital gains so that the Fund won’t have to pay any federal income tax on undistributed income and gains. The Fund intends to distribute any net realized capital gain (whether long-term or short-term gain) at least once a year. Normally, the Fund will declare and pay distributions of net investment income according to the following schedule:

Declaration and Distribution Schedule


Declarations		daily
Distributions		monthly

The Fund may, however, declare and pay distributions of net investment income more frequently.

Different share classes of the Fund usually pay different net investment income distribution amounts, because each class has different expenses. Each time a distribution is made, the net asset value per share of the share class is reduced by the amount of the distribution.

The Fund generally pays cash distributions within five business days after the end of the month in which the distribution was declared. If you sell all of your shares after the record date, but before the payment date, for a distribution, you’ll normally receive that distribution in cash within five business days after the sale was made.

The Fund will automatically reinvest distributions in additional shares of the same share class of the Fund unless you inform us you want to receive your distributions in cash. You can do this by writing Columbia Funds at the address on the back cover, or by calling us at 800.345.6611. No sales charges apply to the purchase or sales of such shares. Distributions of $10 or less will automatically be reinvested in additional Fund shares only. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Unless you are investing through a tax-deferred retirement account (such as an IRA), you should consider avoiding buying Fund shares shortly before the Fund makes a distribution, because doing so can cost you money in taxes. This is because you will, in effect, receive part of your purchase price back in the distribution. This is known as “buying a dividend.” To avoid “buying a dividend,” check the Fund’s distribution schedule above before you invest.

Similarly, if you buy shares of the Fund when it holds securities with unrealized capital gain, you will, in effect, receive part of your purchase price back if and when the Fund sells those securities and distributes the realized gain. This distribution is also subject to tax. The Fund may have, or may build up over time, high levels of unrealized capital gain. If you buy shares of the Fund when it has capital loss carryforwards, the Fund may have the ability to offset future capital gains realized by the Fund that otherwise would have been distributed to shareholders with such carryforwards, although capital loss carryforwards generally expire after eight taxable years and may be subject to substantial limitations.

Taxes and Your Investment

The Fund will send you a statement each year showing how much you’ve received in distributions in the prior year and the distributions’ character for federal income tax purposes. In addition, you should be aware of the following:

The Fund intends to qualify each year as a regulated investment company. A regulated investment company is not subject to tax at the fund level on income and gains from investments that are distributed to shareholders. However, the Fund’s failure to qualify as a regulated investment company would result in fund level taxation, and consequently, a reduction in income available for distribution to you.

Distributions are usually taxable to you when paid, whether they are paid in cash or automatically reinvested in additional shares of the Fund.

Distributions of the Fund’s ordinary income and net short-term capital gain, if any, generally are taxable to you as ordinary income. Distributions of the Fund’s net long-term capital gain, if any, generally are taxable to you as long-term capital gain. Whether capital gains are long-term or short-term is determined by how long the Fund has owned the investments that generated them, rather than how long you have owned your shares.

For taxable years beginning on or before December 31, 2010, if you are an individual and you meet certain holding period and other requirements for your Fund shares, a portion of your distributions may be treated as “qualified dividend income.” Qualified dividend income is income attributable to the Fund’s dividends received from certain U.S. and foreign corporations, as long as the Fund meets certain holding period and other requirements for the stock producing such dividends. The Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

For taxable years beginning on or before December 31, 2010, the maximum individual federal income tax rate on net long-term capital gain and qualified dividend income is 15%.

A sale or exchange of Fund shares is a taxable event. This includes redemptions where you are paid in securities. Your sales (including those paid in securities) and exchanges of Fund shares usually will result in a taxable

capital gain or loss to you, equal to the difference between the amount you receive for your shares (or are deemed to have received in the case of exchanges) and the amount you paid (or are deemed to have paid) for them. Any such capital gain or loss generally will be long-term capital gain or loss if you have held your Fund shares for more than one year at the time of sale or exchange. In certain circumstances, capital losses may be disallowed.

The Fund is required by federal law to withhold tax on any taxable distributions and sale proceeds paid to you (including amounts paid to you in securities and amounts deemed to be paid to you upon an exchange of shares) if: you haven’t provided a correct taxpayer identification number (TIN) or haven’t certified to the Fund that withholding doesn’t apply; the Internal Revenue Service (IRS) has notified us that the TIN listed on your account is incorrect according to its records; or the IRS informs the Fund that you are otherwise subject to backup withholding.

Taxes

The information provided above is only a summary of how federal income taxes may affect your investment in the Fund. It is not intended as a substitute for careful tax planning. Your investment in the Fund may have other tax implications.

It does not apply to certain types of investors who may be subject to special rules, including foreign or tax-exempt investors or those holding Fund shares through a tax-advantaged account, such as a 401(k) plan or IRA.

You should consult with your own tax advisor about the particular tax consequences to you of an investment in the Fund, including the effect of any foreign, state and local taxes, and the effect of possible changes in applicable tax laws.

The financial highlights tables are designed to help you understand how the Fund has performed for the past five full fiscal years, or if shorter, the Fund’s period of operations. Certain information reflects financial results for a single Fund share. The total return line indicates how much an investment in the Fund would have earned each period assuming all dividends and distributions had been reinvested.

This information has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm whose report, along with the Fund’s financial statements, is included in the Fund’s annual report. The independent registered public accounting firm’s report and the Fund’s financial statements are also incorporated by reference into the SAI.

The following supplemental hypothetical investment information provides additional information about the effect of the fees and expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund’s returns over a 10-year period. The charts show the estimated fees and expenses that would be charged on a hypothetical investment of $10,000 in each share class of the Fund, assuming a 5% return each year, the cumulative return after fees and expenses and the hypothetical year-end balance before fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for each share class, which is the same as that stated in the Annual Fund Operating Expense table, is presented in the charts and is net of any contractual fee waivers or expense reimbursements for the period of contractual commitment. Your actual costs may be higher or lower. The charts shown below reflect the maximum initial sales charge. If contingent deferred sales charges were reflected, the “Hypothetical Year-End Balance After Fees and Expenses” amounts shown would be lower and the “Annual Fees and Expenses” amounts shown would be higher.
