A message to our valued clients

In the mutual fund business, success can be measured a number of different ways. Performance is a key measure—the one that gains most attention. But fees and service are also important. In that regard, we are pleased to report that Columbia Management has experienced success on all three fronts over the past year. Even more important, our shareholders have benefited from this success.

Because performance ultimately determines investment success, we have devoted considerable energy to improving the performance of all Columbia funds. And we are happy to report that we have made considerable progress toward this important goal¹.

Columbia has also taken great strides toward making fund operations more cost effective, which has translated into lower expense ratios on many Columbia funds. In this regard, we believe we still have more work to do, and we will continue to explore opportunities for reining in expenses to the benefit of all our shareholders.

On the service front, we have made it easy and convenient for shareholders to do business with us both on the web at www.columbiafunds.com or over the phone at 800.345.6611. In fact, we've recently upgraded our automated phone system with an advanced speech recognition system that allows callers to interact with the system using natural spoken commands.

After secure login, shareholders can buy, sell or exchange funds either online or over the phone. (Buying shares requires that a link has been established between the shareholder's bank account and Columbia.) Up-to-date performance and pricing information is available online and over the phone. At www.columbiafunds.com, shareholders can also update important personal information and get access to prospectuses and fund reports, which reduces paper clutter for shareholders and translates into a reduction of costs for the funds.

At Columbia Management, we think that you'll like what you see as you read the reports for the period ended February 28, 2006. We are committed to continued improvements in an effort to help our shareholders reach their long-term financial goals. And we look forward to continuing to work with you, our valued financial clients, in the years to come.

Sincerely,

Christopher L. Wilson

The "with sales charge" returns include the maximum initial sales charge of 5.75% for class A shares, maximum contingent deferred sales charge of 5.00% for class B and G shares and 1.00% for class C and D shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would have been lower.

Performance results reflect any voluntary waivers or reimbursement of fund expenses by the advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower.

Class Z shares are sold at net asset value with no Rule 12b-1 fees. Class Z shares have limited eligibility and the investment minimum requirement may vary. All results shown assume reinvestment of distributions. Please see the fund's prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each class.

Effective October 13, 2003, class D shares are closed to all new investors and new accounts. Existing class D shareholders will be able to make additional purchases at any time. In addition, the class D sales charge of 1.00% is waived after October 13, 2003.

Classes A, B and D (newer class shares) share performance information includes returns of the fund's class Z shares (the oldest existing fund class) for periods prior to the inception of the newer class shares. The returns for Class C include the returns of Class B prior to 10/13/03, the date on which class C was initially offered by the fund. The returns shown for Class C also include the performance of Class Z prior to the inception of Class B (11/01/02). Class G performance information includes returns of the fund's Class B shares for the period from 11/01/02 through 03/18/05 and for periods prior thereto, the fund's Class Z shares. Class Z share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between class Z shares and the newer class shares. Had the expense differential been reflected, the returns for the periods prior to the inception of classes A, B, C, D and G would have been lower.

Summary

n For the six-month period ended February 28, 2006, the Columbia International Stock Fund's Class A Shares returned 14.43% without sales charge. The fund's return was lower than its benchmarks, the MSCI EAFE Index, which returned 15.14%, and the MSCI All Country World ex US Index, which returned 17.09%.¹ The fund fell just short of the average return of its peer group, the Morningstar Foreign Large Blend Fund Category, which was 14.95%.²

n The fund's out-of-benchmark weight in emerging markets and an above-average weight in Japan detracted from performance. Both markets aided performance in previous periods, and some of the fund's best performers came from emerging and Japanese stock markets during this reporting period. The fund has retained its exposure to both regions. Emerging markets, in particular, appear to offer some of the best opportunities for long-term growth despite intermittent volatility.

n A reduction in the fund's energy position was timely as it locked in gains for the fund before energy commodity prices began to decline – and energy stock prices along with them. A decision to underweight the United Kingdom (UK) also aided performance. A relatively tight monetary policy had a negative impact on UK stocks, and the UK was one of the worst-performing markets for the period.

¹ The MSCI EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the US and Canada. The MSCI All Country World Ex US Index is also an index of global stock market performance that includes developed and emerging markets but excludes the US. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

International investing may involve certain risks, including foreign taxation, currency fluctuations, risks associated with possible differences in financial standards and other monetary and political risks.

Management style is determined by Columbia Management and is based on the investment strategy and process as outlined in the fund's prospectus.

UNDERSTANDING YOUR EXPENSES

Columbia International Stock Fund

Estimating your actual expenses

To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period:

n For shareholders who receive their account statements from Columbia Management Services, Inc., your account balance is available online at www.columbiafunds.com or by calling Shareholder Services at 800.345.6611.

n For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance.

1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6.

2. In the section of the table below titled "Expenses paid during the period," locate the amount for your share class. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period.

As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory, Rule 12b-1 fees and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds.

Analyzing your fund's expenses by share class

To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in each share class during the reporting period. The information in the following table is based on an initial investment of $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and includes the fund's actual expense ratio. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period.

09/01/05 – 02/28/06

	Account value at the beginning of the period ($)				Account value at the end of the period ($)				Expenses paid during the period ($)				Fund's annualized expense ratio (%)
	Actual		Hypothetical		Actual		Hypothetical		Actual		Hypothetical
Class A		1,000.00		1,000.00		1,144.30		1,018.94		6.27		5.91		1.18
Class B		1,000.00		1,000.00		1,141.92		1,015.22		10.25		9.64		1.93
Class C		1,000.00		1,000.00		1,142.02		1,015.22		10.25		9.64		1.93
Class D		1,000.00		1,000.00		1,141.58		1,015.22		10.25		9.64		1.93
Class G		1,000.00		1,000.00		1,141.82		1,015.47		9.98		9.39		1.88
Class Z		1,000.00		1,000.00		1,146.59		1,020.18		4.95		4.66		0.93

Expenses paid during the period are equal to the fund's respective class annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365.

Had the transfer agent not waived a portion of expenses, total return would have been reduced.

It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund and do not reflect any transaction costs, such as sales charges, redemption or exchange fees. Therefore, the hypothetical examples provided will not help you determine the relative total costs of owning shares of different funds. If these transaction costs were included, your costs would have been higher.

Compare with other funds

Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other fund companies, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transaction costs, such as sales charges or redemption or exchange fees.

Summary

n For the six-month period that ended February 28, 2006, the Columbia Mid Cap Growth Fund's Class A Shares returned 15.61% without sales charge. It outperformed both the Russell Midcap Index and the Russell Midcap Growth Index,¹ which returned 8.90% and 9.69%, respectively, for the same period. Its return was also higher than the average return of the Morningstar Mid Cap Growth Funds Category, which was 10.66%.² Strong stock selection across a variety of sectors accounted for the fund's strong performance.

n Stock selection within technology, industrials, health care, financials and telecommunications services made a significant contribution to the fund's return relative to its benchmarks and peer group. The fund's top contributor was Broadcom Corp. (3.0% of net assets), in the technology sector, which enjoyed strong profit growth as the result of higher-than-expected gross margins. Consumer staples stocks were the fund's weakest performers. Tyson Foods, Inc. (0.2% of net assets) was the fund's worst performer, as the company struggled to improve its profit margins.

n In an environment of healthy economic growth and relatively low inflation, the fund's managers maintain a bullish outlook for growth stocks, especially within the energy, materials and industrials sectors. However, decelerating growth could provoke a reassessment of the strength and duration of the current economic expansion. The fund's managers plan to continue to seek the stocks of growth companies with strong earnings prospects and attractive valuations.

¹ The Russell Midcap Index is an index that measures the performance of the 800 smallest companies in the Russell 1000 Index, as ranked by total market capitalization. The Russell Midcap Growth Index is an index that measures the performance of those Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values. Unlike the fund, indices are not investments, they do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

Investing in growth stocks incurs the possibility of losses because their prices are sensitive to changes in current or expected earnings.

Investing in mid-cap stocks may present special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Management style is determined by Columbia Management and is based on the investment strategy and process as outlined in the fund's prospectus.

Summary

n For the six-month period that ended February 28, 2006, Columbia Small Cap Growth Fund I's Class A Shares returned 16.95% without sales charge. It outperformed both the Russell 2000 Index and the Russell 2000 Growth Index, which returned 10.24% and 11.69%, respectively.¹ The fund's return was also higher than the average return of the Morningstar Small Growth Funds Category, which was 11.06%.² The management team's strong stock decisions helped the fund outperform its benchmark and peer group for the period.

n A decision to overweight industrials, one of the period's strongest sectors, aided performance. Ceradyne, Inc. (1.8% of net assets), an industrial company that develops ceramic products and components, was the fund's top contributor. The company benefited from a ramp up in military orders for body and vehicle armor. Information technology and energy sectors also had a positive impact on performance, as did the telecommunications and consumer discretionary sectors, which provided a standout performance from Millicom International Cellular SA (0.9% of net assets). The company, which provides cellular phone service to emerging markets, rose more than 117% during the period. Consumer staples stocks posted a slight decline and the fund's health care holdings underperformed.

¹ The Russell 2000 Index is an index that tracks the performance of the 2,000 smallest of the 3,000 largest US companies based on market capitalization. The Russell 2000 Growth Index is an index that measures the performance of those Russell 2000 Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the fund, indices are not investments, they do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

Investing in growth stocks incurs the possibility of losses because their prices are sensitive to changes in current or expected earnings.

Investments in small-cap stocks may be subject to greater volatility and price fluctuations because they may be thinly traded and less liquid than investments in larger companies.

Management style is determined by Columbia Management and is based on the investment strategy and process as outlined in the fund's prospectus.

UNDERSTANDING YOUR EXPENSES

Estimating your actual expenses

To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period:

n For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance.

1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6.

NAREIT Index

Summary

n For the six-month period ended February 28, 2006, the Columbia Real Estate Equity Fund's Class A Shares returned 9.51% without sales charge. The fund underperformed its benchmark, the NAREIT Index, which returned 11.57%.¹ Its return was also lower than the 11.73% average return of its peer group, the Morningstar Specialty-Real Estate Funds Category.²

n The fund's REIT holdings performed well in a market that was generally favorable for higher-quality REITs. In this environment, apartment REITs were exceptional performers. The rental market strengthened, especially at the high end, as some potential homebuyers were priced out of the market for single-family homes and condominiums. However, performance was dragged down by exposure to investments outside of the conventional REIT market, especially mortgage REITs and a high cash position. A position in hotel stocks also delivered disappointing returns. However, we have maintained the fund's position in hotel stocks in light of improved business prospects for hotels, particularly in higher-end urban markets.

n The fund was restructured when new managers took over in October 2005. Sector weights were brought more in line with its benchmark, and investments outside the real estate market were sold and replaced by securities that were more consistent with the fund's focus on real estate. The fund's new managers also positioned the fund more conservatively, with an emphasis on REITS with high-quality management and the potential for sustainable growth.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

The fund may be subject to the same types of risks associated with direct ownership of real estate including the decline of property value due to general, local and regional economic conditions. In addition, the fund's share price will likely be subject to more volatility than the overall stock market because it concentrates in real estate stocks.

Merrill Lynch 100 Technology Index

Summary

n For the six-month period ended February 28, 2006, the Columbia Technology Fund's Class A Shares returned 24.87% without sales charge. The fund outperformed its benchmark, the Merrill Lynch 100 Technology Index, which returned 12.85%.¹ It also surpassed the average return of its peer group, the Morningstar Specialty – Technology Category, which was 11.62% for the same period.² Semiconductor stocks made the greatest positive impact on fund performance. Wireless telecommunications services also made a strong contribution to the fund's return.

n Within the semiconductor industry, the fund's managers continued to look beyond mega-sized firms to identify growth potential among companies with specific product strengths. The fund had more exposure to wireless stocks than the index, because of positive trends that indicated growing demand and expanded usage for wireless technology. Holdings in systems software detracted from performance.

n The fund remained focused on companies positioned to potentially benefit from the adoption of new technologies, cost savings through outsourcing and key products – especially in the semiconductor industry. The fund's managers plan to continue to evaluate investments in wireless communications.

¹ The Merrill Lynch 100 Technology Index is an equally weighted index of 100 leading technology stocks. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

The share price of a fund that invests primarily in one sector will likely be subject to more volatility than a fund that invests across many sectors. Technology stocks may be more volatile than stocks in other sectors. The fund should be considered part of an overall investment program, and not a complete investment program.

Some of the countries the fund invests in are considered emerging economies, which means there may be greater risks associated with investing there than in more developed countries. In addition, concentration of investments in a single region may result in greater volatility.

Summary

n For the six-month period ended February 28, 2006, the Columbia Strategic Investor Fund's Class A Shares returned 6.06% without sales charge. The fund's return fell between the returns of its two benchmarks, the Russell 3000 Value Index, which returned 7.46%, and the S&P 500 Index, which returned 5.93% for the same period.¹ It fell short of the 7.83% average return of its peer group, the Morningstar Mid-Cap Blend Funds Category.²

n Recognizing that the fund has two benchmarks, the following performance discussion relates to its performance vs. the S&P 500. Good relative performance, especially from the information technology, financials, industrials, energy and materials sector, contributed to solid returns for the fund's equity holdings. The information technology sector made the greatest contribution to relative performance. However, the fund experienced poor relative performance within the consumer discretionary, consumer staples, utilities and healthcare sectors. The weakest relative performance came from the consumer discretionary and the consumer staples sectors. In addition, the fund's cash position, at 18.2% of the portfolio, hampered relative performance as these assets could not keep up with gains in the equity markets.

n In view of their expectation that recent interest-rate increases could slow economic growth in 2006, the fund's management team plans to seek companies with less sensitivity to economic cycles and the ability to maintain stable growth as the economic cycle matures. The managers will continue to evaluate investment opportunities overseas, considering those areas with compelling growth trends and reasonable prices.

¹ The Russell 3000 Value Index is an index that measures the performance of those Russell 3000 Index companies with lower price-to-book ratios and lower forecasted growth values. The S&P 500 Index is an index that tracks the performance of 500 widely held, large capitalization US stocks. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Summary

n For the six-month period that ended February 28, 2006, the Columbia Balanced Fund's Class A Shares returned 3.76% without sales charge. The fund's return was higher than the blended return 3.51% of its two benchmarks based on a 60/40 allocation between them, the S&P 500 Index which returned 5.93% and the Lehman Brothers Aggregate Bond Index which returned negative 0.11%.¹ The fund's return was lower than the average return of its peer group, the Lipper Balanced Funds Category which returned 4.24%.²

n Favorable stock selection, especially within health care and financials, helped the fund's equity holdings outperform its benchmark. The fund was overweight in health care relative to the S&P 500 Index, which meant that superior stock selection had an even more favorable impact on return. These gains were enough to offset weakness among the fund's consumer discretionary stocks. Given recent short-term interest-rate increases and their potential for slowing economic growth, the fund's equity managers plan to focus on companies that they believe can weather a changing economic climate.

n The fund's fixed income holdings performed generally in line with its Lehman benchmark as rising interest rates put pressure on all segments of the bond market. However, short-term yields rose more than long-term yields. In this environment, performance was helped by management's decision to maintain a slightly shorter duration than the benchmark for most of the period. (Duration is a measure of interest-rate sensitivity.) Duration was extended to match the benchmark toward the end of the period as a greater level of uncertainty entered the market with a new Federal Reserve Board chairman and a change in the language used to describe the Fed's interest-rate policy. A decision to overweight mortgage-backed securities, asset-backed securities and corporate bonds also aided performance.

¹ The S&P 500 Index is an index that tracks the performance of 500 widely held, large capitalization US stocks. The Lehman Brothers Aggregate Bond Index is a market value-weighted index that tracks the performance of fixed-rate, publicly placed, dollar denominated, and non-convertible investment grade debt issues. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Equity investments are affected by stock market fluctuations that occur in response to economic and business developments.

Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yield and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa.

Investing in high-yield securities (commonly known as "junk" bonds) offers the potential for high current income and attractive total returns but involves certain risks. Changes in economic conditions or other circumstances may adversely affect a junk bond issuer's ability to make principal and interest payments. Rising interest rates tend to lower the value of all bonds.

Summary

n For the six-month period ended February 28, 2006, the Columbia Oregon Intermediate Municipal Bond Fund's Class A Shares returned 0.65% without sales charge. The fund's return was lower than the 0.84% return of its benchmark, the Lehman Brothers General Obligation Bond Index.¹ However, it was higher than the average return of its peer group, the Lipper Other States Intermediate Municipal Debt Funds Category, which was 0.39%.²

n The fund's short fall versus the benchmark can be accounted for by two factors: It had slightly less exposure than the index to 20-year bonds, which were strong performers. Also, the index includes California bonds, which outperformed the bonds of other states. The fund's mix of higher-yielding investment-grade bonds helped it outperform its peer group.

n Several of the fund's best-performing bonds were pre-refunded during the period. When a bond is pre-refunded, the issuer floats a second bond to pay off the first bond at its first call date. Pre-refunding is generally viewed favorably by investors, and in the case of the pre-refunded bonds in the fund, resulted in total returns between 4% and 5%. Bonds in the hospital sector also did well. Non-callable bonds in the 2010 – 2013 maturity range underperformed as interest rates rose and the differences in yield among short-, intermediate- and long-term bonds narrowed.

¹ The Lehman Brothers General Obligation Bond Index is an index that represents average market-weighted performance of general obligation securities that have been issued in the last five years with maturities greater than one year. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Tax-exempt investing offers current tax-exempt income, but it also involves special risks. The value of the fund will be affected by interest rate changes and the creditworthiness of issues held in the fund. When interest rates go up, bond prices generally drop and vice versa.

Interest income from certain tax-exempt bonds may be subject to certain state and local taxes and, if applicable, the alternative minimum tax. Capital gains are not exempt from income taxes.

Single-state municipal bond funds pose additional risks due to limited geographical diversification.

Management style is determined by Columbia Management and is based on the investment strategy and process as outlined in the fund's prospectus.

The "with sales charge" returns include the maximum initial sales charge of 4.75% for class A shares, maximum contingent deferred sales charge of 5.00% for class B shares and 1.00% for class C and D shares for the first year only. The "without sales charge" returns do not include the effect of sales charges. If they had, returns would have been lower.

Effective October 13, 2003, class D shares are closed to all new investors and new accounts. Existing class D shareholders will be able to make additional purchases at any time. In addition, class D sales charge of 1.00% is waived after October 13, 2003.

Classes A, B and D (newer class shares) share performance information includes returns of the fund's class Z shares (the oldest existing fund class) for periods prior to the inception of the newer class shares. The returns for class C include the returns of class B prior to 10/13/03, the date on which class C was initially offered by the fund. The returns shown for class C also include the performance of class Z prior to the inception of class B (11/01/02). Class Z share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between class Z shares and the newer class shares. Had the expense differential been reflected, the returns for the periods prior to the inception of classes A, B, C and D would have been lower.

Summary

n For the six-month period ended February 28, 2006, the Columbia Conservative High Yield Fund's Class A Shares returned 2.12% without sales charge. It outperformed its benchmarks, the JPMorgan Chase Developed BB High Yield Index and the Merrill Lynch U.S. High Yield, Cash Pay Only Index, which returned 1.46% and 1.90%, respectively.¹ Its return fell just short of the average return of its peer group, the Lipper High Yield Funds Category, which was 2.26%.² Most of the fund's positive return was generated in the final months of the period, as high-yield bonds enjoyed a seasonal rally. Its high-quality orientation aided performance relative to its benchmarks as lower-rated securities struggled to break even during the period.

n A decision to underweight the auto sector relative to the fund's benchmarks also aided return. US auto companies suffered under the weight of weak operating results and concerns about future pension and health care obligations. However, the fund gave up some performance because it had less exposure to wireline and wireless telecommunications stocks, which were strong performers.

n During the period, the fund's new managers brought its industry weights more in line with its benchmarks and broadened the fund's diversification. However, the fund's conservative orientation was preserved, in keeping with management's assessment that the high-yield market is currently fairly valued as well as the fund's overall conservative investment policy.

¹ JPMorgan Chase Developed BB High Yield Index is an index that is designed to mirror the investable universe of the US dollar developed, BB-rated, high yield corporate debt market. The Merrill Lynch U.S. High Yield, Cash Pay Only Index is an index that tracks the performance of non-investment-grade corporate bonds. Unlike the fund, indices are not investments, do not incur fees or expenses and are not professionally managed. It is not possible to invest directly in an index. Securities in the fund may not match those in an index.

Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yields and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa.

The term "conservative" in the Columbia Conservative High Yield Fund's name and as used in the discussion above is intended to describe the Fund's credit approach relative to other high yield funds; the Fund invests primarily in bonds rated Ba or B by Moody's Investors Service, Inc. or BB or B by Standard & Poor's. These lower rated bonds, commonly referred to as "junk bonds", are subject to greater credit risk, and are generally less liquid, than higher-rated, lower yielding bonds. Also changes in economic conditions or other circumstances may adversely affect a junk bond issuer's ability to make principal and interest payments. Rising interest rates tend to lower the value of all bonds.

Management style is determined by Columbia Management and is based on the investment strategy and process as outlined in the fund's prospectus.

UNDERSTANDING YOUR EXPENSES

Columbia Conservative High Yield Fund

Estimating your actual expenses

To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period:

n For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance.

1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6.

Had the transfer agent and distributor not waived a portion of expenses, total return would have been reduced.

All Funds are diversified except for the Columbia Real Estate Equity Fund, Columbia Technology Fund and Columbia Oregon Intermediate Municipal Bond Fund, which are non-diversified.

Investment Goals

Columbia International Stock Fund seeks long-term capital appreciation by investing in stocks issued by companies from at least three countries outside the United States. Columbia Mid Cap Growth Fund seeks significant capital appreciation by investing in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index. Columbia Small Cap Growth Fund I seeks capital appreciation by investing in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Standard & Poor's SmallCap 600 Index. Columbia Real Estate Equity Fund seeks capital appreciation and above-average income by investing in stocks of companies principally engaged in the real estate industry, including real estate investment trusts (REITs). Columbia Technology Fund seeks capital appreciation by investing in stocks of technology companies that may benefit from technological improvements, advancements or developments. Columbia Strategic Investor Fund seeks long-term growth of capital by using a "value" approach to investing primarily in common stocks. Columbia Balanced Fund seeks high total return by investing in common stocks and debt securities. Columbia Oregon Intermediate Municipal Bond Fund seeks a high level of income exempt from federal and Oregon income tax by investing primarily in municipal securities issued by the state of Oregon. Columbia Conservative High Yield Fund seeks a high level of income, with capital appreciation as a secondary goal, by investing in non-investment-grade, corporate debt securities.

Fund Shares

Each Fund may issue an unlimited number of shares. Each of the Funds, except the Columbia International Stock Fund, Columbia Mid Cap Growth Fund and Columbia Small Cap Growth Fund I, offer five classes of shares: Class A, Class B, Class C, Class D and Class Z. Columbia Small Cap Growth Fund I offers four classes of shares: Class A, Class B, Class C and Class Z shares. Columbia Small Cap Growth Fund I commenced offering Class A, Class B and Class C shares on November 1, 2005. Columbia International Stock Fund offers six classes of shares: Class A, Class B, Class C, Class D, Class G and Class Z. Columbia Mid Cap Growth Fund offers eight classes of shares: Class A, Class B, Class C, Class D, Class G, Class R, Class T and Class Z. Effective January 23, 2006, the Columbia Mid Cap Growth Fund is authorized to issue Class R shares. Each share class has its own expense structure.

Class A and Class T shares are subject to a front-end sales charge based on the amount of initial investment. Class A and Class T shares purchased without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% contingent deferred sales charge ("CDSC") on shares sold within twelve months of the time of purchase. Class B and Class G shares are subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will convert to Class A shares in eight years after purchase. Class G shares will convert to Class T shares eight years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class D shares are closed to new investors. Class D shares are subject to a front-end sales charge of 1.00% (which is currently being waived) and a 1.00% CDSC on shares sold within one year after purchase. Class R and Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class R and Class Z shares, as described in each Fund's prospectus.

Note 2. Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements.

Security Valuation

Equity securities and certain investment companies are valued at the last sale price on the principal exchange on which they trade, except for securities traded on the NASDAQ, which are valued at the NASDAQ official close price. Unlisted securities or listed securities for which there were no sales during the day are valued at the closing bid price on such exchanges or over-the-counter markets.

Debt securities generally are valued by pricing services approved by the Funds' Board of Trustees, based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes. Debt securities for which quotations are readily available are valued at an over-the-counter or exchange bid quotation. Certain debt securities, which tend to be more thinly traded and of lesser quality, are priced based on fundamental analysis of the financial condition of the issuer and the estimated value of any collateral. Valuations developed through pricing techniques may vary from the actual amounts realized upon sale of the securities, and the potential variation may be greater for those securities valued using fundamental analysis.

Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value.

Investments in other open-end investment companies are valued at net asset value.Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

Options are valued at the last reported sale price, or in the absence of a sale, the mean between the last quoted bid and ask price.

Foreign securities are generally valued at the last sale price on the foreign exchange or market on which they trade. If any foreign share prices are not readily available as a result of limited share activity, the securities are valued at the last sale price of the local shares in the principal market in which such securities are normally traded.

Generally, trading in foreign securities is substantially completed each day at various times prior to the close of the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. Occasionally, events affecting the values of such foreign securities and such exchange rates may occur between the times at which they are determined and the close of the customary trading session of the NYSE, which would not be reflected in the computation of the Fund's net asset value. If events materially affecting the values of such foreign securities occur and it is determined that market quotations are not reliable, then these foreign securities will be valued at their fair value using procedures approved by the Board of Trustees. The Fund may use a systematic fair valuation model provided by an independent third party to value securities principally traded in foreign markets in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and the time for valuation. If a security is valued at a "fair value", such value is likely to be different from the last quoted market price for the security.

Investments for which market quotations are not readily available, or that have quotations which management believes are not appropriate, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

Security Transactions

Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based

137

February 28, 2006 (Unaudited) Columbia Funds

upon the specific identification method for both financial statement and federal income tax purposes.

Futures Contracts

Certain Funds may invest in municipal and U.S. Treasury futures contracts. The Funds will invest in these instruments to hedge against the effects of changes in the value of portfolio securities due to anticipated changes in interest rates and/or market conditions, for duration management, or when the transactions are economically appropriate to the reduction of risk inherent in the management of the Funds and not for trading purposes. The use of futures contracts involves certain risks, which include: (1) imperfect correlation between the price movement of the instruments and the underlying securities, (2) inability to close out positions due to differing trading hours, or the temporary absence of a liquid market, for either the instrument or the underlying securities, or (3) an inaccurate prediction by Columbia Management Advisors, LLC of the future direction of interest rates. Any of these risks may involve amounts exceeding the variation margin recorded in the Funds' Statement of Assets and Liabilities at any given time.

Upon entering into a futures contract, each Fund deposits cash or securities with the broker in an amount sufficient to meet the initial margin requirement. Subsequent payments are made or received by the Funds equal to the daily change in the contract value and are recorded as variation margin receivable or payable and offset in unrealized gains or losses. Each Fund also identifies portfolio securities as segregated with the broker in a separate account in an amount equal to the futures contract. The Funds recognize a realized gain or loss when the contract is closed or expires.

Options

Certain Funds may write call and put options on futures they own or in which they may invest. Writing put options tends to increase the Funds' exposure to the underlying instrument. Writing call options tends to decrease the Funds' exposure to the underlying instrument. When the Fund writes a call or put option, an amount equal to the premium received is recorded as a liability and subsequently marked-to-market to reflect the current value of the option written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against the amounts paid on the underlying future transaction to determine the realized gain or loss. Each Fund as a writer of an option has no control over whether the underlying future may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the future underlying the written option. There is the risk the Funds may not be able to enter into a closing transaction because of an illiquid market. The Funds' custodian will set aside cash or liquid portfolio securities equal to the amount of the written options contract commitment in a separate account.

Certain Funds may also write call options on a security the Funds own. Writing call options tends to decrease a Fund's exposure to the underlying security. When a Fund writes a call option, an amount equal to the premium received is recorded as a liability. Premiums received from writing call options which have expired are treated as realized gains.

Certain Funds may also purchase put and call options. Purchasing call options tends to increase the Funds' exposure to the underlying instrument. Purchasing put options tends to decrease the Funds' exposure to the underlying instrument. Each Fund pays a premium, which is included in the Funds' Statement of Assets and Liabilities as an investment and subsequently marked-to-market to reflect the current value of the option. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying future transaction to determine the realized gain or loss.

Forward Foreign Currency Exchange Contracts

Forward foreign currency exchange contracts are agreements to exchange one currency for another at a future date at a specified price. These contracts are used to minimize the exposure to foreign exchange rate fluctuations during the period between trade and settlement date of the contracts. Certain Funds may utilize forward foreign currency exchange contracts in connection with the settlement of purchases and sales of securities. Certain Funds may also enter into these contracts to hedge certain other foreign currency denominated assets. Contracts to buy generally are used to acquire exposure to foreign currencies, while

138

February 28, 2006 (Unaudited) Columbia Funds

contracts to sell are used to hedge the Funds' investments against currency fluctuations. Forward currency contracts are valued daily at the current exchange rate of the underlying currency, resulting in unrealized gains (losses) which become realized at the time the foreign currency contracts are closed or mature. Realized and unrealized gains (losses) arising from such transactions are included in net realized and unrealized gains (losses) on foreign currency transactions. The use of forward currency contracts does not eliminate fluctuations in the prices of the Funds' portfolio securities. While the maximum potential loss from such contracts is the aggregate face value in U.S. dollars at the time the contract was opened, exposure is typically limited to the change in value of the contract (in U.S. dollars) over the period it remains open. The Funds could also be exposed to risk if the counterparties of the contracts are unable to fulfill the terms of the contracts.

Treasury Inflation Protected Securities

The Fund may invest in Treasury Inflation Protected Securities ("TIPS"). The principal amount of TIPS is adjusted periodically for inflation based on a monthly published index. Interest payments are based on the inflation-adjusted principal at the time the interest is paid.

Repurchase Agreements

Each Fund may engage in repurchase agreement transactions with institutions that the Funds' investment advisor has determined are creditworthy. Each Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Collateral is at least equal, at all times, to the value of the repurchase obligation including interest. A repurchase agreement transaction involves certain risks in the event of default or insolvency of the counterparty. These risks include possible delays or restrictions upon each Fund's ability to dispose of the underlying securities and a possible decline in the value of the underlying securities during the period while the Funds seek to assert their rights.

Income Recognition

Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Original issue discount is accreted to interest income over the life of the security with a corresponding increase in the cost basis. Corporate actions and dividend income are recorded on the ex-date, except for certain foreign securities which are recorded as soon after ex-date as the Funds become aware of such, net of non-reclaimable tax withholdings. Awards from class action litigation are recorded as a reduction of cost if the Funds still own the applicable securities on the payment date. If the Funds no longer own the applicable securities, the proceeds are recorded as realized gains.

The Funds estimate components of distributions from real estate investment trusts (REITs). Distributions received in excess of income are recorded as a reduction of the cost of the related investments. If the Funds no longer own the applicable securities, any distributions received in excess of income are recorded as realized gains.

Foreign Currency Transactions

The values of all assets and liabilities quoted in foreign currencies are translated into U.S. dollars at that day's exchange rates. Net realized and unrealized gains (losses) on foreign currency transactions include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.

For financial statement purposes, the Funds do not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments.

Determination of Class Net Asset Values

All income, expenses (other than class-specific expenses, as shown on the Statements of Operations) and realized and unrealized gains (losses) are allocated to each class of a Fund on a daily basis for purposes of determining the net asset value of each class. Income and expenses are allocated to each class based on the settled shares method, while realized and unrealized gains (losses) are allocated based on the relative net assets of each class for the Columbia Oregon Intermediate Municipal Bond Fund and Columbia

139

February 28, 2006 (Unaudited) Columbia Funds

Conservative High Yield Fund. For all other Funds, income, expenses (other than class-specific expenses, as shown on the Statements of Operations), and realized and unrealized gains (losses) are allocated to each class of a Fund based on the relative net assets of each class of that Fund.

Federal Income Tax Status

Each Fund intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its taxable income, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, each Fund intends to distribute in each calendar year substantially all of its net investment income, capital gains and certain other amounts, if any, such that each Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign Capital Gains Taxes

Realized gains in certain countries may be subject to foreign taxes at the fund level, at rates ranging from approximately 10% to 15%. The Funds accrue for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction.

Dividends and Distributions to Shareholders

Dividends from net investment income of the Columbia International Stock Fund, Columbia Mid Cap Growth Fund, Columbia Small Cap Growth Fund I, Columbia Technology Fund and Columbia Strategic Investor Fund are declared and paid annually. Dividends from net investment income of the Columbia Real Estate Equity Fund and Columbia Balanced Fund are declared and paid quarterly. Dividends from net investment income of the Columbia Oregon Intermediate Municipal Bond Fund and Columbia Conservative High Yield Fund are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually for all Funds. Additional distributions of net investment income and capital gains for each Fund may be made at the discretion of the Board of Trustees in accordance with federal income tax regulations.

Pricing and Bookkeeping Fees

Columbia is responsible for providing pricing and bookkeeping services to the Funds under a pricing and bookkeeping agreement. Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated those functions to State Street Corporation ("State Street"). As a result, the total fees payable under the pricing and bookkeeping agreement are paid by Columbia to State Street.

Under its pricing and bookkeeping agreement with the Funds, Columbia receives an annual fee of $38,000 paid monthly plus an additional monthly fee based on the level of average daily net assets for the month; provided that during any 12-month period, the aggregate fee shall not exceed $140,000.

Prior to November 1, 2005, Columbia received from each Fund an annual financial accounting fee of $25,000, an annual financial reporting fee of $19,965 and a monthly financial accounting fee at the annual rate of 0.02% of the average daily net assets of each Fund. The combined financial accounting and financial reporting fee for a Fund in any year did not exceed $150,000.

The Funds also reimburse Columbia and State Street for out-of-pocket expenses and charges, including fees payable to third parties for pricing each Fund's portfolio securities and direct internal costs incurred by Columbia in connection with providing fund accounting oversight and monitoring and certain other services. For the six months ended February 28, 2006, the annualized effective pricing and bookkeeping fee rates for the Funds, inclusive of out-of-pocket expenses, as a percentage of the Funds' average daily net assets, were as follows:

Transfer Agent Fee

Columbia Management Services, Inc. (formerly Columbia Funds Services, Inc.) (the "Transfer Agent"), an affiliate of Columbia and an indirect, wholly-owned subsidiary of BOA, provides shareholder services to the Funds and has contracted with Boston Financial Data Services ("BFDS") to serve as sub-transfer agent. The Transfer Agent is entitled to receive a fee, paid monthly, at the annual rate of $15.23 per open account plus sub-transfer agent fees (exclusive of BFDS fees) calculated based on assets held in omnibus accounts and intended to recover the cost of payments to third parties for services to those accounts. The Transfer Agent may also retain, as additional compensation for its services, fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcript fees due the Transfer Agent from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts the Transfer Agent

143

February 28, 2006 (Unaudited) Columbia Funds

maintains in connection with its services to the Funds. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. Prior to November 1, 2005, the Transfer Agent received a monthly fee at the annual rate of $28.00 per open account for each Fund except Columbia Oregon Intermediate Municipal Bond Fund and Columbia Conservative High Yield Fund, which paid $34.00 per open account. The Transfer Agent was also reimbursed for certain out-of-pocket expenses.

Columbia has voluntarily agreed to waive a portion of the transfer agent fees for the Columbia International Stock Fund, Columbia Mid Cap Growth Fund and Columbia Strategic Investor Fund. For the period September 1, 2005 through October 31, 2005, the Transfer Agent voluntarily waived a portion of its fees to reflect the reduced contractual fees charged to the Funds effective November 1, 2005. For the six months ended February 28, 2006, fees waived by the Transfer Agent and the annualized effective fee rates for the Funds, inclusive of out-of-pocket expenses and net of fee waivers, as a percentage of the Funds' average daily net assets, were as follows:

(a) The Fund's Board of Directors currently limits payments under the Plan for Class A shares to 0.25% annually of the Class A average daily net assets.

(b) The Distributor has contractually agreed to limit a portion of the Class G distribution and service fees so that combined the fee does exceed 0.95% annually of the Class G shares average daily net assets. Of the 0.50% service fee, 0.25% relates to shareholder liaison fees and 0.25% relates to administration support fees.

The Distributor has voluntarily agreed to waive a portion of the Class C and Class D distribution and service fees so that combined these fees do not exceed the annual rates on the average daily net assets of Class C and Class D shares of each Fund as follows:

Columbia Oregon Intermediate Municipal Bond Fund					0.65	%
Columbia Conservative High Yield Fund					0.85	%

The CDSC and the distribution fees received from the Plan are used principally as repayment to the Distributor for amounts paid by the Distributor to dealers who sold such shares.

Shareholder Services Fees

The Columbia Mid Cap Growth Fund has adopted shareholder services plans that permit the Fund to pay for certain services provided to Class T shareholders by its financial advisors. The annual service fee may equal up to 0.50% annually for Class T shares, but will not exceed the Fund's net investment income attributable to Class T shares. The Columbia Mid Cap Growth Fund does not intend to pay more than 0.30% for annual Class T shareholder services fees.

Expense Limits and Fee Reimbursements

Columbia has voluntarily agreed to waive fees and reimburse the Columbia Technology Fund for certain expenses so that total expenses (exclusive of service fees, distribution fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) will not exceed 1.65% annually of the Fund's average daily net assets. This arrangement may be revised or discontinued by Columbia at any time.

Custody Credits

Each Fund has an agreement with its custodian bank under which custody fees may be reduced by balance credits. These credits are recorded as a reduction of total expenses on the Statement of Operations. The Funds could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if they had not entered into such an agreement.

The Board of Trustees has appointed a Chief Compliance Officer to the Funds in accordance with federal securities regulations. The Funds, along with other affiliated funds, pay their pro-rata share of the expenses associated with the Chief Compliance Officer. Each Fund's expenses for the Chief Compliance Officer will not exceed $15,000 per year.

Note 7. Line of Credit

The Funds and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit provided by State Street Bank and Trust Company. Borrowings are used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%.

For the six months ended February 28, 2006, the Funds, other than the Columbia International Stock Fund, Columbia Small Cap Growth Fund I and Columbia Real Estate Equity Fund did not borrow under this arrangement.

Note 8. Shares of Beneficial Interest

As of February 28, 2006, the Funds had shareholders whose shares were beneficially owned by participant accounts over which Bank of America and/or its affiliates had either sole or joint investment discretion.

Note 9. Disclosure of Significant Risks and Contingencies

Concentration of Credit Risk

Columbia Oregon Intermediate Municipal Bond Fund holds investments that are insured by private insurers who guarantee the payment of principal and interest in the event of default or that are supported by a letter of credit. The insurers are rated Aaa by Moody's Investors Services, Inc.

At February 28, 2006, private insurers who insured greater than 5% of the total investments of the Columbia Oregon Intermediate Municipal Bond Fund were as follows:

Columbia Oregon Municipal Bond Fund

Insurer	% of Total Investments
Financial Guaranty Insurance Co.		13.7	%
MBIA Insurance Corp.		12.1
Financial Security Assurance, Inc.		11.7
Ambac Assurance Corp.		6.7

Foreign Securities

There are certain additional risks involved when investing in foreign securities that are not inherent with investments in domestic securities. These risks may involve foreign currency exchange rate fluctuations, adverse political and economic developments and the possible prevention of currency exchange or other foreign governmental laws or restrictions. In addition, the liquidity of foreign securities may be more limited than that of domestic securities.

Investments in emerging market countries are subject to additional risk. The risk of foreign investments is typically increased in less developed countries. These countries are also more likely to experience high levels of inflation, deflation or currency devaluation which could hurt their economies and securities markets.

Geographic Concentration

Columbia Oregon Intermediate Municipal Bond Fund has greater than 5% of its total investments on February 28, 2006 invested in debt obligations issued by the state of Oregon and its political subdivisions, agencies and public authorities. This Fund is more susceptible to economic and political factors adversely affecting issuers of the state's municipal securities than are municipal bond funds that are not concentrated to the same extent in these issuers.

High-Yield Securities

Investing in high-yield securities may involve greater credit risk and considerations not typically associated with investing in U.S. government bonds and other higher quality fixed income securities. These securities are non-investment grade securities, often referred to as "junk" bonds. Economic downturns may disrupt the high yield market and impair the ability of issuers to repay principal and interest. Also, an increase in interest rates would likely have an adverse impact on the value of such obligations. Moreover, high-yield securities may be less liquid to the extent that there is no established secondary market.

Industry Focus

The Funds may focus its investments in certain industries, subjecting them to greater risk than a fund that is more diversified.

Issuer Focus

As non-diversified funds, the Columbia Real Estate Equity Fund, the Columbia Technology Fund and the Columbia Oregon Intermediate Municipal Bond Fund may invest a greater percentage of their total assets in the securities of fewer issuers than a diversified fund. The Funds may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

Legal Proceedings

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"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as

148

February 28, 2006 (Unaudited) Columbia Funds

outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has 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 certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees 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 will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

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 in detail 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 several 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. As to Columbia, the Distributor and the Trustees of the Columbia Funds, 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 along with related claims under Section 48(a) of the ICA were not dismissed.

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

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder

149

February 28, 2006 (Unaudited) Columbia Funds

class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. 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 purpose. 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 ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

For the six months ended February 28, 2006, Columbia has assumed legal, consulting services and Trustees' fees incurred by the Funds in connection with these matters as follows:

Columbia International Stock Fund	$	7,937
Columbia Mid Cap Growth Fund		5,217
Columbia Small Cap Growth Fund I		1,264
Columbia Real Estate Equity Fund		4,613
Columbia Technology Fund		531
Columbia Strategic Investor Fund		3,066
Columbia Balanced Fund		1,792
Columbia Oregon Intermediate Municipal Bond Fund		2,462
Columbia Conservative High Yield Fund		8,484

Note 10. Business Combinations & Mergers

BOARD CONSIDERATION AND APPROVAL OF INVESTMENT ADVISORY AGREEMENTS

Columbia Funds

The Advisory Fees and Expenses Committee of the Board of Trustees meets one or more times annually, usually in late summer, to review the advisory agreements (collectively, the "Agreements") of the funds for which the Trustees serve as trustees or directors (each a "fund") and determine whether to recommend that the full Board approve the continuation of the Agreements for an additional one-year period. After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements. In addition, the Board, including the Independent Trustees, considers matters bearing on the Agreements at most of its other meetings throughout the year and meets regularly with the heads of each investment area within Columbia. The Trustees also meet with selected fund portfolio managers at various times throughout the year.

The Trustees receive and review all materials that they, their legal counsel or Columbia, the funds' investment adviser, believe to be reasonably necessary for the Trustees to evaluate the Agreements and determine whether to approve the continuation of the Agreements. Those materials generally include, among other items, (i) information on the investment performance of each fund relative to the performance of peer groups of mutual funds and the fund's performance benchmarks, (ii) information on each fund's advisory fees and other expenses, including information comparing the fund's expenses to those of peer groups of mutual funds and information about any applicable expense caps and fee "breakpoints," (iii) sales and redemption data, (iv) information about the profitability of the Agreements to Columbia, and potential "fall-out" or ancillary benefits that Columbia and its affiliates may receive as a result of their relationships with the funds and (v) information obtained through Columbia's response to a questionnaire prepared at the request of the Trustees by counsel to the funds and independent legal counsel to the Independent Trustees. The Trustees also consider other information such as (vi) Columbia's financial results and financial condition, (vii) each fund's investment objective and strategies and the size, education and experience of Columbia's investment staffs and their use of technology, external research and trading cost measurement tools, (viii) the allocation of the funds' brokerage, if any, including allocations to brokers affiliated with Columbia and the use of "soft" commission dollars to pay fund expenses and to pay for research products and services, (ix) Columbia's resources devoted to, and its record of compliance with, the funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (x) Columbia's response to various legal and regulatory proceedings since 2003 and (xi) the economic outlook generally and for the mutual fund industry in particular. In addition, the Trustees confer with their independent fee consultant and review materials relating to the Agreements that the independent fee consultant provides. Throughout the process, the Trustees have the opportunity to ask questions of and request additional materials from Columbia and to consult independent legal counsel to the Independent Trustees.

The Board of Trustees most recently approved the continuation of the Agreements at its October, 2005 meeting, following meetings of the Advisory Fees and Expenses Committee held in August, September, and October, 2005. In considering whether to approve the continuation of the Agreements, the Trustees, including the Independent Trustees, did not identify any single factor as determinative, and each weighed various factors as he or she deemed appropriate. The Trustees considered the following matters in connection with their approval of the continuation of the Agreements:

The nature, extent and quality of the services provided to the funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by Columbia and its affiliates to the funds and the resources dedicated to the funds by Columbia and its affiliates. Among other things, the Trustees considered (i) Columbia's ability, including its resources, compensation programs for personnel involved in fund management, reputation and other attributes, to attract and retain highly qualified research, advisory and supervisory investment professionals; (ii) the portfolio management services provided by those investment professionals; and (iii) the trade execution services provided on behalf of the funds. For each fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds offering exposure to a variety of asset classes and investment disciplines and providing for a variety of fund and shareholder services. After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the

151

Columbia Funds

nature, extent and quality of services provided supported the continuation of the Agreements.

Investment performance of the funds and Columbia. The Trustees reviewed information about the performance of each fund over various time periods, including information prepared by an independent third party that compared the performance of each fund to the performance of peer groups of mutual funds and performance benchmarks. The Trustees also reviewed a description of the third party's methodology for identifying each fund's peer group for purposes of performance and expense comparisons. The Trustees also considered additional information that the Advisory Fees and Expenses Committee requested from Columbia relating to funds that presented relatively weaker performance and/or relatively higher expenses.

In the case of each fund that had performance that lagged that of a relevant peer group for certain (although not necessarily all) periods, the Trustees concluded that other factors relevant to performance were sufficient, in light of other considerations, to warrant continuation of the fund's Agreements. Those factors varied from fund to fund, but included one or more of the following: (i) that the fund's performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the fund's investment strategy and policies and that the fund was performing as expected, given market conditions and the fund's investment strategy; (iii) that the fund's performance was competitive when compared to other relevant performance benchmarks or peer groups; (iv) that Columbia had taken or was taking steps designed to help improve the fund's investment performance, including, but not limited to, replacing portfolio managers or modifying investment strategies; (v) that the fund's advisory fee had recently been, or was proposed to be, reduced, with the goal of helping the fund's net return to shareholders become more competitive; and (vi) that other fund expenses, such as transfer agency or fund accounting fees, have recently been reduced, with the goal of helping the fund's net return to shareholders become more competitive.

The Trustees also considered Columbia's performance and reputation generally, the funds' performance as a fund family generally, and Columbia's historical responsiveness to Trustee concerns about performance and Columbia's willingness to take steps intended to improve performance.

After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of each fund and Columbia was sufficient, in light of other considerations, to warrant the continuation of the Agreements.

The costs of the services provided and profits realized by Columbia and its affiliates from their relationships with the funds. The Trustees considered the fees charged to the funds for advisory services as well as the total expense levels of the funds. That information included comparisons (provided both by management and by an independent third party) of the funds' advisory fees and total expense levels to those of their peer groups and information about the advisory fees charged by Columbia to comparable accounts. In considering the fees charged to comparable accounts, the Trustees took into account, among other things, management's representations about the differences between managing mutual funds as compared to other types of accounts, including the additional resources required to effectively manage mutual funds and distribute mutual fund shares. In evaluating each fund's advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the fund. The Trustees considered reductions in advisory fee rates, implementation of advisory fee breakpoints, institution of advisory fee waivers, and changes to expense caps, which benefited a number of the funds. Furthermore, the Trustees considered the projected impact on expenses resulting from the overall cost reductions that management anticipated would result from the shift to a common group of service providers for transfer agency, fund accounting and custody services for mutual funds advised by Bank of America affiliates. The Trustees also noted management's stated justification for the fees charged to the funds, which included information about the performance of the funds, the services provided to the funds and management's view as to why it was appropriate that some funds bear advisory fees or total expenses greater than their peer group medians.

The Trustees also considered the compensation directly or indirectly received by Columbia and its affiliates from their relationships with the funds. The Trustees reviewed information provided by management as to

152

the profitability to Columbia and its affiliates of their relationships with the funds, and information about the allocation of expenses used to calculate profitability. When reviewing profitability, the Trustees also considered court cases in which adviser profitability was an issue in whole or in part, the performance of the relevant funds, the expense levels of the funds, and whether Columbia had implemented breakpoints and/or expense caps with respect to the funds.

After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each of the funds were fair and reasonable, and that the costs of the advisory services generally, and the related profitability to Columbia and its affiliates of their relationships with the funds, supported the continuation of the Agreements.

Economies of Scale. The Trustees considered the existence of any economies of scale in the provision of services by Columbia to each fund and whether those economies were shared with the fund through breakpoints in the investment advisory fees or other means, such as expense waivers. The Trustees noted that many of the funds benefited from breakpoints, expense caps, or both. In considering those issues, the Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to Columbia and its affiliates of their relationships with the funds, as discussed above.

After reviewing those and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the funds supported the continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but were not limited to the following:

• the extent to which each fund had operated in accordance with its investment objective and its record of compliance with its investment restrictions, and the compliance programs of the funds and Columbia. They also considered the compliance-related resources that Columbia and its affiliates were providing to the funds.

• the nature, quality, cost and extent of administrative and shareholder services performed by Columbia and its affiliates, both under the Agreements and under separate agreements for the provision of transfer agency and administrative services.

• so-called "fall-out benefits" to Columbia, such as the engagement of its affiliates to provide distribution, brokerage and transfer agency services to the funds, and the benefits of research made available to Columbia by reason of brokerage commissions generated by the funds' securities transactions, as well as possible conflicts of interest associated with those fall-out and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor those possible conflicts of interest.

• the draft report provided by the independent fee consultant, which included information about and analysis of the funds' fees, expenses and performance.

Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel and the independent fee consultant, the Trustees, including the Independent Trustees, approved the continuance of each of the Agreements through October 31, 2006.

SUMMARY OF MANAGEMENT FEE EVALUATION
BY INDEPENDENT FEE CONSULTANT

Columbia Funds

Prepared Pursuant to the February 9, 2005
Assurance of Discontinuance
between the Office of
Attorney General of New York State and
Columbia Management Advisors, Inc. and
Columbia Funds Distributor, Inc.

October 11, 2005

I. Overview

Columbia Management Advisors, Inc. ("CMA") and Columbia Funds Distributors, Inc. ("CFD") (CFD together with CMA referred to herein as Columbia Management Group or "CMG¹"), entered into an agreement with the New York Attorney General's Office in the form of an Assurance of Discontinuance (the "AOD"). The AOD stipulated that CMA would be permitted to manage or advise the Columbia Funds only if the Independent Members (as such term is defined in the AOD) of the Columbia Funds' Board of Trustees/Directors (collectively the "Trustees") appointed a Senior Officer or an Independent Fee Consultant ("IFC") who, among other things, is to manage the process by which management fees are negotiated. On May 15, 2005, the Independent Members of the Board appointed me as the IFC for the Columbia Funds. This report is the annual written evaluation of the Columbia Funds for 2005 that I have prepared in my capacity as IFC, as required by the AOD.

A. Duties of the Independent Fee Consultant

As part of the AOD, the Independent Members of the Columbia Funds' Board of Trustees/Directors agreed to retain an independent fee consultant who was to participate in the management fee negotiation process. The IFC is charged with "... duties and responsibilities [that] include managing the process by which proposed management fees (including, but not limited to, advisory fees) to be charged the Columbia Fund[s] are negotiated so that they are negotiated in a manner which is at arms length and reasonable and consistent with this Assurance of Discontinuance." However, the IFC does not replace the Trustees in their role of negotiating management and other fees with CMG and its affiliates. In particular, the AOD states that "Columbia Advisors may manage or advise a Columbia Fund only if the reasonableness of the proposed management fees is determined by the Board of Trustees of the Columbia Fund using ... an annual independent written evaluation prepared by or under the direction of the ... Independent Fee Consultant...." This report, pursuant to the AOD, constitutes the "annual independent written evaluation prepared by or under the direction of the... Independent Fee Consultant."

The AOD requires the IFC report to consider at least the following:

a) Management fees (including any components thereof) charged by other mutual fund companies for like services;

b) Management fees (including any components thereof) charged to institutional and other clients of CMA for like services;

c) Costs to CMA and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit;

d) Profit margins of CMA and its affiliates from supplying such services;

e) Possible economies of scale as the CMA fund grows larger; and

f) The nature and quality of CMA services, including Columbia Funds' performance.

This report is designed to assist the Board in evaluating the 2005 contract renewal for Columbia Funds. In addition, this report points out areas where the Board may deem additional information and analysis to be appropriate over time.

B. Sources of Information Used in My Evaluation

I have requested data from CMG and various third party industry data sources or independent research companies that work in the mutual fund arena. The following list generally describes the types of information I requested.

1. I collected data on performance, management fees, and expense ratios of both Columbia Funds and

¹ Prior to the date of this report, CMA merged into an affiliated entity, Banc of America Capital Management, LLC ("BACAP"), and BACAP then changed its name to Columbia Management Advisors, LLC which carries on the business of CMA, and CFD changed its name to Columbia Management Distributors, Inc.

Columbia Funds

comparable non-Columbia Funds. The sources of this information were CMG, Lipper Inc. ("Lipper") and Morningstar Inc. ("Morningstar"). While Lipper and Morningstar each selected a different group of peer funds it deemed appropriate against which to measure the relative performance and fees of Columbia Funds, I conducted an independent review of the appropriateness of each peer group.

2. I reviewed data on CMG's expense and profitability that I obtained from CMA directly.

3. I have reviewed data on the organizational structure of CMG in general.

4. I collected information on profitability from Strategic Insight Mutual Fund Research and Consulting, LLC ("Strategic Insight"). I used this third-party independent research as an additional method to gauge the accuracy of the data collected in (2) above.

5. I conducted interviews with various CMG staff, including members of the senior management team, legal staff, heads of affiliates, portfolio managers, and financial personnel.

6. I reviewed current 2005 Section 15(c) material provided to the Board and material presented to the Board in the 2004 fee and performance evaluation.

7. I have reviewed various academic research papers, industry publications, and other available literature dealing with mutual fund operations, profitability, and other issues. In addition, I have reviewed SEC releases and studies of mutual fund expenses.

8. I have reviewed documents pertaining to recent mutual fund litigation in general and publicly available information about litigation where CMG has been involved.

In addition, I have engaged NERA Economic Consulting ("NERA") and independent consultant Dr. John Rea to assist me in data management and analysis. Both NERA and Dr. Rea have extensive experience in the mutual fund industry through consulting, government positions, or industry trade groups that provide unique insights and special knowledge pertaining to my independent analysis of fees, performance, and profitability. I have also retained Shearman & Sterling LLP as outside counsel to advise me in connection with my review.

C. Qualifications and Independence

I am the Walter H. Carpenter Chair and Professor of Finance at Babson College. Before this I was the Chief Economist of the U.S. Securities and Exchange Commission. I have no material relationship with Bank of America or CMG aside from acting as IFC, and am aware of no relationship with any of their affiliates. [Resume omitted]

II. EVALUATION OF THE GENERAL PROCESS USED TO NEGOTIATE THE ADVISORY CONTRACT

A. General Considerations

My analysis considered all factors and information I reviewed on the finances and operations of Columbia Funds. I gave each factor an appropriate weight in my overall findings, and no single factor was in itself the sole criterion for a finding or conclusion. My objective was to assess all of the information provided and conduct a robust evaluation of Columbia Funds' operations, fees, and performance.

My analysis and thought processes will and, I believe, should, differ in certain ways from the processes used by Trustees in their evaluation of the management agreements. In particular, because of my technical and quantitative background, I may use techniques and data that Trustees have not previously felt would be useful. I view this supplemental analysis as appropriate because my role is to assist Trustees in their decisions, and to the extent that I bring new ideas or analysis to the evaluation, I believe this improves the process by which management fees for the Columbia Funds may be negotiated in accordance with the AOD.

Finally, as part of my role as IFC, I have, from time to time, sent to Trustees additional papers and reports produced by third parties that I felt had bearing on the fee negotiation process. I viewed these materials as educational in nature and felt they would aid Trustees in placing their work in context.

B. CMG Management Interviews

As a starting point of my analysis, I have met with members of CMG staff to gain an understanding of the organizational structure and personnel involved in running the Columbia fund family.

I have had general discussions and have received information about the management structure of CMG.

155

Columbia Funds

My conversations with management have been informative. In addition, I have participated in Board meetings where Trustees and management have discussed issues relating to management agreements and performance of Columbia Funds. When I felt it was appropriate, I added my opinions on particular matters, such as fund performance or fee levels, to the discussion.

C. Trustees' Fee and Performance Evaluation Process

After making initial requests for information, members of the Trustees of the Columbia Funds met in advance of the October Section 15(c) contract approval meeting to review certain fee, performance and other data for the Columbia Funds and to ask questions and make requests of management. Trustees have developed a process to evaluate the fee and expense levels and performance of Columbia Funds. This process is used to highlight those funds that have been performing poorly, may have had higher management fees or expense ratios, or both.

The process involves providing instructions to Lipper to prepare specific data analyses tailored to the Trustees review framework. These instructions include highlighting funds that hit one or more fee performance "screens." The six screens the Trustees use are as follows:

a. 5th Lipper quintile in actual management fee;

b. 5th Lipper quintile in total expense ratio;

c. Three or more 5th Lipper quintile rankings in the 1-, 3-, 5- or 10-year performance rankings;

d. Sum of the Lipper Quintile Rank (1-year performance) and the Lipper Quintile Rank (actual management fee) totals a number equal to or higher than 8;

e. Sum of the Lipper Quintile Rank (1-year performance) and the Lipper Quintile Rank (total expense ratio) totals a number equal to or higher than 8; and

f. Sum of the Lipper Quintile Rank (3-year performance) and the Lipper Quintile Rank (total expense ratio) totals a number equal to or higher than 8.

If a fund hits one or more of these screens, it is highlighted for additional review by the Trustees. This method is only used as an aid for Trustees to highlight funds and is not the sole test of whether the Board will determine to take particular actions concerning fees or performance. Funds that have not been flagged by this screen also may be singled out for fee and performance reasons, and the Trustees may determine not to take action with respect to the fees or performance of funds that have been flagged by the screen. These screens contribute to the basis for discussions on Trustees' views on the Columbia Funds.

III. FINDINGS

My findings based on my work as IFC are as follows:

1. The Trustees have the relevant information necessary to form an opinion on the reasonableness of fees and evaluate the performance of the Columbia Funds. The process the Trustees used in preparing to reach their determination has been open and informative. In my view, the 2005 process by which the management fees of the Columbia Funds have been negotiated thus far has been, to the extent practicable, at arm's length and reasonable and consistent with the AOD.

2. Columbia Funds demonstrated a range of performance relative to their peers. I find that across the fund complex, 54.26 percent of Columbia Funds have performance higher than the median of their respective Lipper performance universe, and 42.55 percent of Columbia Funds have performance higher than the median of their respective Lipper performance group. In addition, Lipper performance universe and group comparison showed that Columbia Funds were distributed roughly evenly across these quintiles. The Trustees have worked with management to address issues of funds that have demonstrated consistent or significant underperformance.

3. Columbia Funds demonstrate a range of management fees and expense ratios relative to their peers. I find that across the fund complex, 58.51 percent of Columbia Funds have expenses below the median of their Lipper expense universe, and 53.19 percent of Columbia Funds have expenses below the median of their Lipper expense group. In addition, Lipper expense universe and group comparisons show that Columbia Funds are distributed roughly evenly across these quintiles. The Trustees have taken steps to limit shareholder expenses for certain funds having management fees significantly above their peers, often though the use of fee waivers to which CMG has agreed.

156

Columbia Funds

Consolidation of various funds and fund families managed by CMG has resulted in substantial savings in non-advisory expenses.

4. Profitability to CMG of the individual funds ranges widely, but the overall profitability to CMG of its relationship with the Columbia Funds appears to fall within a reasonable range. The method of cost allocation to funds is addressed in the material provided by CMG to the Trustees, but additional information may be necessary to make a judgment on fund level profitability. My review of profitability and cost allocation is ongoing, and I plan to continue to develop my views with regard to fund level profitability.

5. Columbia Funds have instituted fee schedules with breakpoints designed to enable investors to benefit from fund economies of scale, although 71% of the funds have not yet reached their first breakpoint. My analysis of the appropriateness of the breakpoint levels, which I expect will take into account the cost and profitability of the individual funds, is ongoing.

My work is ongoing and my views may develop over time in light of new information and analysis.

Respectfully submitted,
Erik R. Sirri
