NOT FDIC MAY LOSE VALUE INSURED NO BANK GUARANTEE TO OUR FELLOW SHAREHOLDERS COLUMBIA NEWPORT ASIA PACIFIC FUND DEAR SHAREHOLDER: We are pleased to let you know that FleetBoston Financial Corporation and Bank of America Corporation have merged, effective April 1, 2004. As as a result of the merger, Columbia Management Group became part of the Bank of America family of companies. Looking ahead, we believe this merger will be a real benefit to our shareholders. Preserving and leveraging our strengths, the combined organization will deliver additional research, management, and product capabilities to you. There are no immediate changes planned for fund names, product lines, or customer service contacts. As always, we will provide you with updates at www.columbiafunds.com or through other communications, such as newsletters and shareholder reports. As you might know, on March 15, 2004, FleetBoston Financial announced an agreement in principle with the staff of the Securities and Exchange Commission ("SEC") and the New York Attorney General to settle charges involving market timing in Columbia Management mutual funds. (Bank of America came to a similar settlement in principle at the same time.) The agreement will require the final approval of the SEC. This action reflects our full cooperation with the investigation and our strong wish to put this regrettable situation behind us. Columbia Management has taken and will continue to take steps to strengthen policies, procedures and oversight to curb frequent trading of Columbia fund shares. We also want you to know that your fund's Board of Trustees has been energetic over the past year in strengthening its capacity to oversee the Columbia funds. Recently, the Board of Trustees: - ELECTED AN INDEPENDENT TRUSTEE TO CHAIR THE TWELVE-PERSON BOARD. IN ADDITION, EACH COMMITTEE OF THE BOARD IS COMPRISED OF TRUSTEES WHO ARE COMPLETELY INDEPENDENT OF THE ADVISOR AND ITS AFFILIATES. - APPOINTED A CHIEF COMPLIANCE OFFICER OF THE COLUMBIA FUNDS, WHO REPORTS DIRECTLY TO EACH FUND'S AUDIT COMMITTEE. TRUSTEES WERE ALSO ASSIGNED TO FOUR SEPARATE INVESTMENT OVERSIGHT COMMITTEES, EACH BETTER ABLE TO MONITOR PERFORMANCE OF INDIVIDUAL FUNDS. - VOTED TO DOUBLE THE REQUIRED INVESTMENT BY EACH TRUSTEE IN THE COLUMBIA FUNDS -- TO FURTHER ALIGN THE INTERESTS OF THE TRUSTEES WITH THOSE OF OUR FUND SHAREHOLDERS. AT THE SAME TIME, NEW POLICIES WERE INSTITUTED REQUIRING ALL INVESTMENT PERSONNEL AND TRUSTEES TO HOLD THEIR COLUMBIA FUND SHARES FOR A MINIMUM OF ONE YEAR (UNLESS EXTRAORDINARY CIRCUMSTANCES WARRANT AN EXCEPTION TO BE GRANTED BY A BOARD DESIGNATED COMMITTEE). Both your fund's trustees and Columbia Management are committed to serving the interests of our shareholders, and we will continue to work hard to help you achieve your financial goals.

Most Asian economies benefited as consumer and business spending increased. Exporting countries, such as Hong Kong and Taiwan, also benefited from a worldwide increase in demand for products manufactured in Asia. Japan's economy experienced its fastest growth in almost 14 years. Stock market performance reflected Asia's robust economic growth. For the six-month reporting period, the MSCI AC Asia Pacific Index returned 20.42%. STOCK MARKETS LIFTED BY FAVORABLE ECONOMIC NEWS Equity market performance reflected the region's robust economic growth. In Japan, the outlook for improved corporate earnings was reflected in the 24.50% return of the Nikkei 225 in 2003. The Nikkei 225 tracks the investment returns of 225 of Japan's top-rated companies. Solid performance continued into 2004, with the Nikkei up 3.42% through February. Throughout the region known as Greater China (People's Republic of China, Hong Kong and Taiwan), stocks tied to domestic consumption, business expansion and construction spending were market leaders. In the smaller markets of Thailand, Malaysia, and Indonesia, investors were also rewarded with solid returns. However, some of the strongest performers in 2003--namely Thailand and India--gave back some of their outsized returns early in 2004. JAPAN TURNED A CORNER While a rising yen limited exports of Japanese products, GDP growth in Japan was reported at 7% for 2003. This robust rate raised hopes that Japan is finally on a steady path to sustainable recovery. Growth was buoyed by a resolution to lingering bad load problems, an upturn in industrial production and machinery orders and a boom in exports. However, job growth was lackluster and consumers remain cautious about spending. GROWTH RANGES FROM MODEST TO ROBUST IN GREATER CHINA In Greater China, GDP growth during the reporting period ranged from modest in Hong Kong and Taiwan to robust in China. In Hong Kong, unemployment declined and domestic retail sales moved higher as the economy continued to recover. In Taiwan, sustained demand for consumer goods, a recovery in capital goods expenditures, a pickup in construction activity and increased government spending in an election year contributed to a strengthening economy. Taiwan also benefited from the global recovery in the technology sector because it is a major exporter of computer-related goods. In China, growth exceeded 9% in 2003. Estimates for growth in 2004 are somewhat lower, because the government has taken steps to cool down an economy on the verge of overheating. The People's Bank of China (PBOC) began to limit the number of loans it generates for construction and land development projects. As a result, credit growth slowed over the last year. Forecasts call for growth between 7.2% to 8.5% for 2004. [SIDENOTE] SUMMARY FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 29, 2004 - - THE STOCK MARKETS OF ASIA REFLECTED ROBUST ECONOMIC GROWTH THROUGHOUT THE REGION. THE MSCI AC ASIA PACIFIC INDEX RETURNED 20.42%.

The MSCI AC Asia Pacific Index is an unmanaged index that tracks the performance of stocks traded on stock exchanges in Pacific Basin countries. 3 <Page> PORTFOLIO MANAGERS' REPORT COLUMBIA NEWPORT ASIA PACIFIC FUND For the six-month period ended February 29, 2004, class A shares of Columbia Newport Asia Pacific Fund returned 13.81% without sales charge. That was less than the return of the fund's benchmark, the MSCI AC Asia Pacific Index, which was 20.42% for the same period. The fund also underperformed the 19.61% average return of its peer group, the Lipper Pacific Region Funds Category.(1) HIGHER-QUALITY COMPANIES UNDERPERFORMED As many lower-quality Japanese companies went from bad to better, due to their improved balance sheets and their potential for earnings growth, investors bid up their stock prices and the higher-quality companies that the fund emphasized came up short by comparison. The rising value of the yen was also instrumental in the fund's performance shortfall. As the yen strengthened, investors grew concerned that higher prices on technology products sold outside Japan would cause sales and earnings growth to slow and stock prices to fall. JAPANESE COMPANIES PROSPEROUS AS ECONOMY IMPROVED At 49% of the portfolio, Japan was the fund's largest country position. As the Japanese economy improved, we became enthusiastic about the prospects for companies positioned to benefit from increased consumer spending. We sold some of our export-related companies, particularly in the technology sector. We also added banks, such as UFJ Holdings, which helped total return. Mitsubishi Tokyo Financial, which was in the portfolio for several months, also aided the fund's return. Our investments in Aoyama Trading, a specialty men's retailer, and Yoshinoya D&C, a fast food restaurant, also contributed to return. FOCUS ON NEW OPPORTUNITIES We sold some holdings in China to invest in new opportunities. Because China's economic growth has been extraordinary, the government has become concerned about the prospects for rising inflation and has taken steps to tighten the availability of credit, which could have a negative impact on stocks. While China's economic growth should be robust by global standards, we expect it to slow in response to this move. In re-allocating assets, we favored countries with strong growth in domestic consumption and infrastructure development, such as India. The Indian economy has benefited from relatively low interest rates and expansion in the manufacturing and service sectors. To capitalize on rising consumer spending, we purchased Maruti Udyog, a manufacturer of low cost automobiles for the domestic population. We also added to the fund's stake in Taiwan. Although the Taiwan market trailed other Asian markets in 2003, we believe Taiwan could do well in 2004 if its economy improves. Stock valuations and the prospects (1) Lipper Inc., a widely respected data provider in the industry, calculates an average total return for mutual funds with similar investment objectives as those of the fund.

LOOKING TOWARD ECONOMIC EXPANSION ACROSS ASIA Our outlook for the next several months is positive. We expect economic growth throughout Asia to improve and, while inflation may rise slightly, we believe interest rates will remain relatively low. We have positioned the portfolio to take advantage of consumer trends that we believe could benefit from growing domestic economies. We also continue to own export-driven companies that should do well in a stronger global economy.

Portfolio holdings are organized by type of asset, industry, country or geographic region (if applicable) to demonstrate areas of concentration and diversification. STATEMENT OF ASSETS AND LIABILITIES This statement details the fund's assets, liabilities, net assets and share price for each share class. Net assets are calculated by subtracting all the fund's liabilities (including any unpaid expenses) from the total of the fund's investment and non-investment assets. The share price for each class is calculated by dividing net assets for that class by the number of shares outstanding in that class as of the last day of the reporting period. STATEMENT OF OPERATIONS This statement details income earned by the fund and the expenses charged to the fund. The Statement of Operations also shows any net gain or loss the fund realized on the sales of its holdings during the period, as well as any unrealized gains or losses recognized over the period. The total of these results represents the fund's net increase or decrease in net assets from operations. STATEMENT OF CHANGES IN NET ASSETS This statement demonstrates how the fund's net assets were affected by its operating results, distributions to shareholders and shareholder transactions (e.g., subscriptions, redemptions and dividend reinvestments). The Statement of Changes in Net Assets also reconciles changes in the number of shares outstanding.

See notes to financial statements. 15 <Page> NOTES TO FINANCIAL STATEMENTS FEBRUARY 29, 2004 (UNAUDITED) COLUMBIA NEWPORT ASIA PACIFIC FUND NOTE 1. ORGANIZATION Columbia Newport Asia Pacific Fund (the "Fund"), a series of Columbia Funds Trust VI (the "Trust"), is a diversified portfolio. The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. INVESTMENT GOAL The Fund seeks long-term growth by investing primarily in equity securities of companies located in Asia or the Pacific Basin. FUND SHARES The Fund may issue an unlimited number of shares and offers four classes of shares: Class A, Class B, Class C and Class Z. Each share class has its own sales charge and expense structure. Class A shares are subject to a maximum front-end sales charge of 5.75% based on the amount of initial investment. Class A shares purchased without an initial sales charge are subject to a 1.00% contingent deferred sales charge ("CDSC") on shares sold within eighteen months on an original purchase of $1 million to $25 million. Class B 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 a certain number of years after purchase, depending on the program under which shares were purchased. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class Z shares, as described in the Fund's prospectus. Effective October 13, 2003, the Fund changed its name from Liberty Newport Asia Pacific Fund to Columbia Newport Asia Pacific Fund. Also on that date, the Trust changed its name from Liberty Funds Trust VI to Columbia Funds Trust VI. 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 Fund in the preparation of its financial statements. SECURITY VALUATION Foreign securities are generally valued at the closing 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. Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value. 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 2:00 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 readily available, then these foreign securities will be valued at their fair value using procedures approved by the Board of Trustees. SECURITY TRANSACTIONS Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes. REPURCHASE AGREEMENTS The Fund may engage in repurchase agreement transactions with institutions that the Fund's investment advisor has determined are creditworthy. The 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 16 <Page> certain risks in the event of default or insolvency of the counterparty. These risks include possible delays or restrictions upon the 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 Fund seeks to assert its rights. INCOME RECOGNITION Interest income is recorded on the accrual 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 Fund becomes aware of such, net of non-reclaimable tax withholdings. 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 Fund does 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 Statement of Operations), and realized and unrealized gains (losses), are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class. 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 30%. The Fund accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction. FEDERAL INCOME TAX STATUS The 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, by distributing in each calendar year substantially all of its net investment income, capital gains and certain other amounts, if any, the Fund will not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded. DISTRIBUTIONS TO SHAREHOLDERS Distributions to shareholders are recorded on ex-date. Net realized capital gains, if any, are distributed at least annually. NOTE 3. FEDERAL TAX INFORMATION Unrealized appreciation and depreciation at February 29, 2004, based on cost of investments for federal income tax purposes and excluding any unrealized appreciation and depreciation from changes in the value of assets and liabilities resulting from changes in exchange rates, was: <Table> Unrealized appreciation $ 3,130,526 Unrealized depreciation (586,462) Net unrealized appreciation $ 2,544,064 </Table> The following capital loss carryforwards, determined as of August 31, 2003, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: <Table> <Caption> YEAR OF EXPIRATION CAPITAL LOSS CARRYFORWARD - ----------------------------------------------------------------------------------- 2005 $ 2,391,127 2009 3,676,821 2010 1,404,163 2011 953,897 $ 8,426,008 </Table> NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES INVESTMENT ADVISORY FEE Columbia Management Advisors, Inc. ("Columbia") is the investment advisor to the Fund. Prior to April 1, 2004, Columbia was an indirect, wholly owned subsidiary of FleetBoston Financial Corporation ("FleetBoston"). Effective April 1, 2004, FleetBoston 17 <Page> was acquired by Bank of America Corporation ("BOA"), see note 10. Columbia receives a monthly investment advisory fee based on the Fund's average daily net assets at the following annual rates: <Table> <Caption> AVERAGE DAILY NET ASSETS FEE RATE - ---------------------------------------------------------------------------- First $1 billion 0.95% Next $500 million 0.90% Over $1.5 billion 0.85% </Table> Prior to November 1, 2003, Columbia was entitled to receive a monthly investment advisory fee at the annual rate of 1.00% of the Fund's average daily net assets. For the six months ended February 29, 2004, the Fund's annualized effective investment advisory fee rate was 0.96%. ADMINISTRATION FEES Columbia provides administrative and other services to the Fund. Effective November 1, 2003, the Board of Trustees approved an administration fee reduction for the Fund. As a result of the fee reduction, Columbia no longer receives fees from the Fund for its administration services. Prior to November 1, 2003, Columbia was entitled to receive a monthly administration fee at the annual rate of 0.25% of the Fund's average daily net assets. For the six months ended February 29, 2004, the Fund's annualized effective administration fee rate was 0.07%. PRICING AND BOOKKEEPING FEES Columbia is responsible for providing pricing and bookkeeping services to the Fund under a pricing and bookkeeping agreement. Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated those functions to State Street Corporation ("State Street"). Columbia pays the total fees collected to State Street under the Outsourcing Agreement. Under its pricing and bookkeeping agreement with the Fund, Columbia receives from the Fund an annual flat fee of $10,000 paid monthly, and in any month that the Fund's average daily net assets exceed $50 million, an additional monthly fee. The additional fee rate is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement. This rate is applied to the average daily net assets of the Fund for that month. The Fund also pays additional fees for pricing services. For the six months ended February 29, 2004, the Fund's annualized effective pricing and bookkeeping fee rate was 0.100%. TRANSFER AGENT FEES Columbia Funds Services, Inc. (the "Transfer Agent"), formerly Liberty Funds Services, Inc., an indirect, wholly owned subsidiary of BOA, provides shareholder services to the Fund. For such services, the Transfer Agent receives a fee, paid monthly, at the annual rate of $28.00 per open account. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. Prior to November 1, 2003, the Transfer Agent was entitled to receive a monthly transfer agent fee, in addition to reimbursement for certain out-of-pocket expenses, at the annual rate of 0.06% of the Fund's average daily net assets plus flat-rate charges based on the number of shareholder accounts and transactions. For the six months ended February 29, 2004, the Fund's annualized effective transfer agent fee rate, exclusive of out-of-pocket fees, was 0.39%. UNDERWRITING DISCOUNTS, SERVICE AND DISTRIBUTION FEES Columbia Funds Distributor, Inc. (the "Distributor"), an indirect, wholly owned subsidiary of BOA, is the principal underwriter of the Fund. Prior to October 13, 2003, Columbia Funds Distributor, Inc. was known as Liberty Funds Distributor, Inc. For the six months ended February 29, 2004, the Distributor has retained net underwriting discounts of $9,947 on sales of the Fund's Class A shares and received CDSC fees of $5, $1,746 and $252 on Class A, Class B and Class C share redemptions, respectively. The Fund has adopted a 12b-1 plan (the "Plan") which requires the payment of a monthly service fee to the Distributor at the annual rate of 0.25% of the average daily net assets attributable to Class A, Class B and Class C shares of the Fund. The Plan also requires the payment of a monthly distribution fee to the Distributor at the annual rate of 0.75% of the average daily net assets attributable to Class B and Class C shares only. The CDSC and the 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. 18 <Page> EXPENSE LIMITS AND FEE REIMBURSEMENTS Columbia has voluntarily agreed to waive certain fees to the extent that total expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) exceed 1.90% annually of the Fund's average daily net assets. This arrangement may be revised or discontinued by Columbia at any time. CUSTODY CREDITS The Fund has an agreement with its custodian bank under which custody fees may be reduced by balance credits. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. FEES PAID TO OFFICERS AND TRUSTEES The Fund pays no compensation to its officers, all of whom are employees of Columbia or its affiliates. The Fund's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Fund's assets. NOTE 5. PORTFOLIO INFORMATION For the six months ended February 29, 2004, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $6,428,374 and $3,042,355, respectively. NOTE 6. REDEMPTION FEES Effective February 10, 2003, the Fund began imposing a 2.00% redemption fee to shareholders of Class Z shares who redeem shares held for 60 days or less. Redemption fees, which are retained by the Fund, are accounted for as an addition to paid in capital and are allocated to each class proportionately for purposes of determining the net asset value of each class. Prior to October 9, 2003, redemption fees were recorded as a component of paid in capital on Class Z shares. For the six months ended February 29, 2004, the redemption fees for the Class Z shares of the Fund amounted to $2,271. NOTE 7. LINE OF CREDIT The Fund and other affiliated funds participate in a $350,000,000 credit facility, which is used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to the Fund based on its borrowings. In addition, the Fund has agreed to pay commitment fees on its pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. For the six months ended February 29, 2004, the Fund did not borrow under these arrangements. NOTE 8. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES GEOGRAPHIC CONCENTRATION Because the Fund's investments are concentrated in Asia and the Pacific Basin, events within the region will have a greater effect on the Fund than if the Fund were more geographically diversified. In addition, events in any one country within the region may impact the other countries or the region as a whole. Markets in the region can experience significant volatility due to social, regulatory and political uncertainties. 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. INDUSTRY FOCUS The Fund may focus its investments in certain industries, subjecting it to greater risk than a fund that is more diversified. 19 <Page> LEGAL PROCEEDINGS Columbia, the Distributor, and certain of their affiliates (collectively, "The Columbia Group") have received information requests and subpoenas from various regulatory and law enforcement authorities in connection with their investigations of late trading and market timing in mutual funds. The Columbia Group has not uncovered any instances where Columbia or the Distributor were knowingly involved in late trading of mutual fund shares. On February 24, 2004, the Securities and Exchange Commission ("SEC") filed a civil complaint in the United States District Court for the District of Massachusetts against Columbia and the Distributor, alleging that they had violated certain provisions of the federal securities laws in connection with trading activity in mutual fund shares. Also on February 24, 2004, the New York Attorney General ("NYAG") filed a civil complaint in New York Supreme Court, County of New York against Columbia and the Distributor alleging that Columbia and the Distributor had violated certain New York anti-fraud statutes. If either Columbia or the Distributor is unsuccessful in its defense of these proceedings, it could be barred from serving as an investment advisor or distributor for any investment company registered under the Investment Company Act of 1940, as amended (a "registered investment company"). Such results could prevent Columbia, the Distributor or any company that is an affiliated person of Columbia and the Distributor from serving as an investment advisor or distributor for any registered investment company, including your fund. Your fund has been informed by Columbia and the Distributor that, if these results occur, they will seek exemptive relief from the SEC to permit them to continue to serve as your fund's investment advisor and distributor. There is no assurance that such exemptive relief will be granted. On March 15, 2004, Columbia and the Distributor entered into agreements in principle with the SEC Division of Enforcement and NYAG in settlement of the charges. Under the agreements, Columbia and the Distributor agreed, inter alia, to the following conditions: payment of $70 million in disgorgement; payment of $70 million in civil penalties; an order requiring Columbia and the Distributor to cease and desist from violations of the antifraud provisions and other provisions of the federal securities laws; governance changes designed to maintain the independence of the mutual fund boards of trustees and ensure compliance with securities laws and their fiduciary duties; and retention of an independent consultant to review Columbia's and the Distributor's compliance policies and procedures. The agreement requires the final approval of the SEC. In a separate agreement with the NYAG, the Columbia Group has agreed to reduce mutual fund fees by $80 million over a five-year period. 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. NOTE 9. COMPARABILITY OF FINANCIAL STATEMENTS The Fund has changed its fiscal year end from June 30 to August 31. NOTE 10. SUBSEQUENT EVENT On April 1, 2004, FleetBoston, including the Fund's investment advisor and distributor, was acquired by BOA. The merger did not change the way the Fund is managed, the investment personnel assigned to manage the Fund or the fees paid by the Fund. 20 <Page> FINANCIAL HIGHLIGHTS COLUMBIA NEWPORT ASIA PACIFIC FUND SELECTED DATA FOR A SHARE OUTSTANDING THROUGHOUT EACH PERIOD IS AS FOLLOWS: <Table> <Caption> (UNAUDITED) SIX MONTHS PERIOD ENDED ENDED FEBRUARY 29, AUGUST 31, YEAR ENDED JUNE 30, CLASS A SHARES 2004 2003 (a) 2003 2002 2001 - ------------------------------------------------------------------------------------------------------------------------------ NET ASSET VALUE, BEGINNING OF PERIOD $ 14.48 $ 12.87 $ 14.47 $ 16.50 $ 24.55 - ------------------------------------------------------------------------------------------------------------------------------ INCOME FROM INVESTMENT OPERATIONS: Net investment loss (c) (0.08) (0.01) (0.03) (0.08) (0.04) Net realized and unrealized gain (loss) on investments, foreign currency and foreign capital gains tax 2.08 1.62 (1.57) (1.95) (7.38) ------------ ------------ ------------ ------------ ------------ Total from Investment Operations 2.00 1.61 (1.60) (2.03) (7.42) - ------------------------------------------------------------------------------------------------------------------------------ LESS DISTRIBUTIONS DECLARED TO SHAREHOLDERS: From net investment income -- -- -- -- -- From net realized gains -- -- -- -- (0.18) In excess of net realized gains -- -- -- -- (0.45) ------------ ------------ ------------ ------------ ------------ Total Distributions Declared to Shareholders -- -- -- -- (0.63) - ------------------------------------------------------------------------------------------------------------------------------ REDEMPTION FEES: Redemption fees added to paid-in capital --(c)(e) -- -- -- -- - ------------------------------------------------------------------------------------------------------------------------------ NET ASSET VALUE, END OF PERIOD $ 16.48 $ 14.48 $ 12.87 $ 14.47 $ 16.50 Total return (f)(g) 13.81%(h) 12.51%(h) (11.06)% (12.30)% (30.60)% - ------------------------------------------------------------------------------------------------------------------------------ RATIOS TO AVERAGE NET ASSETS/ SUPPLEMENTAL DATA: Operating expenses (i) 2.15%(j) 2.15%(j) 2.15% 2.15% 2.15% Interest expense -- -- --%(k) --%(k) -- Net investment loss (i) (0.98)%(j) (0.36)%(j) (0.24)% (0.55)% (0.22)% Waiver/reimbursement 1.52%(j) 2.16%(j) 1.40% 1.74% 1.26% Portfolio turnover rate 23%(h) 8%(h) 42% 24% 43% Net assets, end of period (000's) $ 8,128 $ 5,343 $ 4,620 $ 6,804 $ 9,222 <Caption> PERIOD ENDED JUNE 30, CLASS A SHARES 2000 1999 (b) - ------------------------------------------------------------------------ NET ASSET VALUE, BEGINNING OF PERIOD $ 19.01 $ 10.00 - ------------------------------------------------------------------------ INCOME FROM INVESTMENT OPERATIONS: Net investment loss (c) (0.16)(d) (0.02)(d) Net realized and unrealized gain (loss) on investments, foreign currency and foreign capital gains tax 7.03 9.14 ------------ ------------ Total from Investment Operations 6.87 9.12 - ------------------------------------------------------------------------ LESS DISTRIBUTIONS DECLARED TO SHAREHOLDERS: From net investment income (0.50) (0.11) From net realized gains (0.83) -- In excess of net realized gains -- -- ------------ ------------ Total Distributions Declared to Shareholders (1.33) (0.11) - ------------------------------------------------------------------------ REDEMPTION FEES: Redemption fees added to paid-in capital -- -- - ------------------------------------------------------------------------ NET ASSET VALUE, END OF PERIOD $ 24.55 $ 19.01 Total return (f)(g) 36.18% 91.64%(h) - ------------------------------------------------------------------------ RATIOS TO AVERAGE NET ASSETS/ SUPPLEMENTAL DATA: Operating expenses (i) 2.15% 2.15%(j) Interest expense -- -- Net investment loss (i) (0.65)% (0.15)%(j) Waiver/reimbursement 0.96% 3.10%(j) Portfolio turnover rate 31% 26%(h) Net assets, end of period (000's) $ 10,213 $ 4,606 </Table> (a) The Fund has changed its fiscal year end from June 30 to August 31.
