Are the investing rules the same for managing small-cap/mid-cap funds and large-cap funds? Here are some of my personal opinions on these questions. We believe some basic principles apply to any stock portfolio. (1) Diversification reduces risk, so own mid-cap stocks (Columbia Acorn Select) and a small-cap fund (Columbia Acorn USA). (2) International stocks add additional beneficial diversification (Columbia Acorn International) 1. (3) The market often over-values growth stocks, so pay close attention to valuation. (4) Big winners take years to develop, so think long term. So what are the differences in managing small-, mid-and large-cap funds? Many large-company portfolios are run according to the rules expressed in Charles Ellis's book, WINNING THE LOSER'S GAME. 2 He tells us to play it safe. Start with a portfolio that mirrors the market and try to avoid big losers (fraud such as Enron and WorldCom, overpriced growth such as Cisco at $80 3). One could say he starts with the S&P 500 and reduces it to the Ellis 495 by getting rid of some potential big losers. The WINNING THE LOSER'S GAME strategy may work for a big-company portfolio, but it is not the way I like to run a small-cap fund. Small-cap is a winner's game. You want to be a Barry Bonds or a Sammy Sosa and hit 50 home runs. If you get the homers, you are a hero; you can strike out a lot of times but no one will care very much. As an example, International Game Technology (IGT) has been a great long-term winner for the funds. In the 2003 season, IGT hit a grand slam - an additional unrealized gain of $175 million! 4 Even if you strike out more often than you would like, one big winner more than offsets a half-dozen $10 million losers. Some of our big winners are duly celebrated in the Scarlet A section. The funds had fine results in 2003 due to the success we had in these stocks and many others. Writing about success, however, is less colorful than writing about failure; there are more plays about Nero than about Marcus Aurelius. When it comes to investing, there are only a few ways to fail. You can buy a company that runs into unexpected problems. Sometimes you buy into a speculative company you know is high risk and the company just doesn't make it. The unfortunate speculators who bought Cisco at $80 lost mere hundreds of billions of dollars compared to the more unfortunate speculators gulled by the Enron and WorldCom frauds. Of course bubbles and speculation have a long history. The first overpricing bubble on record was the tulip-mania boom in Holland in 1636. Tulips were a new "high-tech" flower in Europe but the price of strangely colored varieties went way too high, creating a nasty collapse. Tulip-bulb farming today is still important to the Dutch but it is no longer high tech. Farmers can fool you. About 25 years ago, I put some personal money into Maine Sugar. The promoter was a potato processor in Aroostook County, Maine. He believed that the climate and soil there was favorable for growing sugar beets. He floated stock to build a sugar refinery and invited a planeload of New York analysts to come see the sugar beet fields under cultivation. The analysts got on a bus and were driven to a field where the CEO dug up a giant sugar beet. The analysts had never seen such a large sugar beet (most of them had never seen a farm, for that matter). They got back on the bus, and after another ten minutes arrived at another field. The CEO dug up a sugar beet bigger than the first one. The bus continued to another farm field where again an impressive beet was unearthed. When the analysts arrived back in New York, they wrote buy reports based on the great number of farms growing sugar beets. Maine Sugar dissolved a few months later, and the city-boy analysts realized that they had been shown the same field three times in a row. (Columbia Acorn Funds didn't own Maine Sugar). The latest foolish farm fraud is Parmalat, an Italian company in the milk business. (Parma latte, get it?) The Columbia Acorn Funds lost a few million dollars in Parmalat (see Pages 6 and 10). Big banks that did business with Parmalat could lose hundreds of millions of dollars in bad loans. One of the centerpieces of the fraud was a made-up bank deposit of 3.95 billion euros (about $5 billion). The Parmalat officials allegedly handed the auditors a hastily forged document purporting to be the bank's acknowledgement of the deposit. The auditors appear to have accepted the false affidavit without making their own inquiry ("Hey, we are facing a deadline and it's only five billion.") and allowed the company to continue its fraud for a few more months, roping us in. How could we have avoided getting caught? Talking to company management more often probably would have not helped at all; after all, the bank lenders, the bond rating agencies, and auditor were fooled, and they had much freer access to the company's internal records then any outside financial analyst could ever get. One answer would have been to talk to Parmalat's suppliers, in this case the dairy farmers. After the collapse, someone did ("Parma Farmers Had One Rule: Don't Deal With Parmalat," BLOOMBERG NEWS, January 19, 2004). Achille Coelli, director of the Union of Parma Farmers said, "Farmers here won't work with Parmalat. Tanzi [the CEO] never had a good reputation. The company was a slow payer, so only one 1-800-922-6769 2 percent of the milk produced in Parma province was sold to Parmalat." Obvious red flag? Sure. Did any analyst do this check before the collapse? Don't think so. What conclusions do we want to draw from this crying over spilt milk, besides the vaguely comforting notion that not all fraud occurs in the USA? First, a smart crook can fool some of the people all of the time. Second, really star-quality analytic work could help discover frauds sooner, but much of the time that doesn't happen. Third, complete skepticism would have you avoid fraud, but you would avoid the good investments too. An investor must balance skepticism and credulity just as one balances risk/return or growth/value. Fourth, diversification dilutes the negative effect of one bad stock. Since fraud tends to hit you one at a time, it's a strike out, but it doesn't cost you the season. The benefits you get from big winners far outweigh a few losers. 2003 SCARLET A WINNERS HEAP HIGH THE GOLDEN CORN! 5 -- JOHN GREENLEAF WHITTIER Our analysts and portfolio managers deserve a lot of credit for picking exceptional stocks but we do not rely solely on our internal investment prowess. Often we get sage advice from investment pros outside our Chicago office. We honor and thank these individuals by presenting them with the coveted Scarlet A certificate. In 2003, domestic stocks had to increase more than 150% and make more than $40 million to be considered for a Scarlet A. The international stock criteria was a return of at least 100% and a dollar gain of $20 million or more. Our thanks to Greg Jackson of Blum Capital Partners for his help on software company NOVELL. The stock was up 214% in 2003 and brought in a firm-wide gain of over $101 million. Rural cellular service provider WESTERN WIRELESS was up 250% in 2003 and provided a dollar gain of nearly $69 million. Hats off to Thomas Lee of JPMorgan for his help with this 2003 winner. Thomas confirmed our internal analysis that Western Wireless was generating free cash flow and that fears that the company could go bust were unfounded. Natural gas producer ULTRA PETROLEUM, up nearly 150%, brought in a dollar gain of over $50 million. Credit for this idea goes to Barry Sahgal of Brean Murray & Co. While this is Barry's first Scarlet A win, this is not his first contribution to the Columbia Acorn Funds. Barry also brought EVERGREEN RESOURCES to our attention in 1998, a stock that has increased over 270% during the five years we've held it in our funds. A repeat winner tops our international Scarlet A list. Ireland's ANGLO IRISH BANK was up 142% in 2003 and provided a firm-wide dollar gain of nearly $60 million. To David Smith of Davy Stockbrokers in Dublin: Thanks again! Stefan Stalmann of Dresdner Kleinwort Wasserstein in Frankfurt, Germany, earns the Scarlet A for his help with DEPFA BANK. The stock, up 139% with a $22 million gain, provides international public-sector financing. While we had built a position in Depfa Bank before speaking with Stefan, his understanding of the company reinforced our conviction and we remained invested in the stock longer than we might have on his advice, benefiting shareholders. It is noteworthy that Robert Hurkmans, a Dresdner contact in New York, encouraged us to contact Stefan. The best attributes of a good broker are credibility and being selective about providing information and analyst contacts within their own organization. So, to Robert Hurkmans, we offer kudos for darned good brokering. COLUMBIA WAM NEWS John Park has been named director of domestic research for Columbia Wanger Asset Management, L.P.

McQuaid Photo of Robert A. Mohn Photo of John H. Park Columbia Acorn Fund surged 45.68% in 2003, our fourth best year ever. As shown on Page 1, the Fund matched the Russell 2500, slightly underper-formed the Russell 2000, handily beat many peers and substantially outperformed the large cap S&P 500. During the fourth quarter, Columbia Acorn Fund's 14.45% gain matched small-cap performance measures and moderately beat mid- and large-cap benchmarks. We've previously discussed buying good tech stocks at distressed prices, and also purchasing select telecom and biotech stocks when we believed we were being paid to take risk. Most of these stocks were up a lot, but given improved tech demand, repaired telecom balance sheets, and biotech fundamental progress, we believe additional gains seem plausible for many of the holdings. We constantly review the Fund's portfolio, looking to swap into stocks that we consider more attractive. Aspect Communications, discussed separately on this page, was Columbia Acorn Fund's biggest percentage winner, up 454% during the year. Barcode and wireless ID systems maker Unova jumped 354% on improved earnings, while software provider Novell, technology e-learning company Skillsoft Publishing, and technology staff company Igate Capital each at least doubled. The Fund's biggest loser was First Health Group, down over 20%, as competitors put pricing pressure on the firm. Columbia Acorn Fund's foreign stocks delivered an average 57.81% return for the year. The leading percentage gainer was Korean auto parts maker Hyundai Mobis, which cranked out a 171% gain on better than expected earnings. Anglo Irish Bank, discussed on Page 6, appreciated 125% and was the Fund's largest foreign winner in dollars. We continue to believe that foreign stocks on average are better values than domestic securities, so we have increased the Fund's foreign weighting to 12.7%. We currently don't expect it to exceed 15%. Small caps have outperformed large caps for nearly five years and by most measures small-cap valuations are now close to long-term average valuations relative to large caps. While we continue to find companies that we believe are attractive, the combination of fewer compelling new ideas and more existing stocks approaching sell targets has caused the Board of Trustees to take proactive steps to reduce cash inflows. Existing shareholders can continue to buy shares in Columbia Acorn Fund. The minimum for NEW eligible accounts, however, has been raised to $50,000 and several marketing channels have been closed. Please see our recent prospectus supplement for additional details. We'd like to take this opportunity to officially welcome John Emerson to Columbia Wanger Asset Management's domestic analyst team. John joined us mid-year to cover media stocks. /s/ Charles P. McQuaid /s/ Robert A. Mohn Charles P. McQuaid Robert A. Mohn LEAD PORTFOLIO MANAGER CO-PORTFOLIO MANAGER /s/ John H. Park John H. Park CO-PORTFOLIO MANAGER The Right Call - -------------------------------------------------------------------------------- Columbia Wanger Asset Management's technology services and software analyst Ben Andrews always believed that technology was driving a revolution in the telecommunications industry. Though telecom-related stocks collapsed from early 2000 to early 2003, consumers worldwide still wanted hand-held devices and broadband connections, while corporations wanted increased productivity and cost savings. Call center software provider Aspect Communications suffered from management, product, and financing transitions, but had a stable customer base that generated plenty of revenue. As the economy improved, Aspect's next generation products started to grow, and the company's financing and management problems were worked out. Aspect became profitable and the stock rose over 450% in 2003. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. INVESTMENTS IN FOREIGN SECURITIES HAVE SPECIAL RISKS, INCLUDING POLITICAL OR ECONOMIC INSTABILITY, HIGHER COSTS, DIFFERENT REGULATIONS, ACCOUNTING STANDARDS, TRADING PRACTICES AND LEVELS OF INFORMATION, AND CURRENCY EXCHANGE RATE FLUCTUATIONS. * LIBERTY ACORN FUND WAS RENAMED COLUMBIA ACORN FUND ON OCTOBER 13, 2003.

Mendes III Columbia Acorn International finished 2003 on a strong note. The Fund was up 17.35% for the quarter, outperforming both the 15.97% gain of the Citigroup EMI Global ex-US Index and the 17.08% return of the MSCI EAFE Index. For the year, the Fund's return of 47.80% fell short of the Citigroup EMI Global ex-US return of 55.02% but beat the MSCI EAFE return of 38.59%. Stocks outside the Fund's core strategy, mainly stocks in the basic materials sector, soared during the year, dampening the Fund's return. Even though the Fund didn't beat the benchmark Citigroup EMI Global ex-US Index, the absolute return for the year is the third best in Columbia Acorn International's history. The best stocks in the quarter and year came from a variety of industries. ASE Test, a semiconductor packaging and testing company in Taiwan, rose 72% on a recovery in demand for semiconductors. For the year, the stock was up 271%. Improved sales drove home a 69% fourth quarter gain for South Korean auto parts maker Hyundai Mobis and an annual gain of 197%. Other winners included Global BioChem Technology Group, a maker of corn starch and corn gluten headquartered in Hong Kong, up 64% in the quarter and 137% for the year; United Services Group, a temporary staffing service in the Netherlands, up 57% in the quarter and 114% for 2003; and Anglo Irish Bank, a niche middle-market bank in Ireland and the Fund's largest holding, up 48% in the fourth quarter and 125% for the year. A problem stock for the quarter was Zapf Creation, a toy manufacturer in Germany, down on weakness in its U.S. doll business. The company has made changes to its U.S. sales organization and plans to introduce new products in 2004. We believe these changes should help Zapf regain traction in the important U.S. market. The Fund's small position in Italian dairy producer Parmalat fell 55% in the quarter when it was revealed that a huge cash reserve on its books was falsified. The Fund minimized losses in the stock by halving the position when concerns first surfaced. Laggards for the year included Ireland's Waterford Wedgewood, down 51%. Its highly leveraged position hurt the stock in a year when luxury good purchases, particularly in the household goods sector, were subdued. The stock was also hurt by the weakened U.S. dollar. Singapore's Star Cruises also sank in the annual period, down 40%. The company's heavy reliance on Asian gambling cruises to support its large debt worried investors following the SARS outbreak and the expansion of gambling operations within Asia. We sold the Fund's position in the stock. We are pleased to introduce a new member to Columbia Wanger Asset Management's international analyst team. Kenneth Wooden joined the firm in early December to cover Japanese equities. Ken spent 17 years investing in Japan and is a welcome addition to the team. /s/ P. Zachary Egan /s/ Louis J. Mendes III P. Zachary Egan Louis J. Mendes III CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER Anglo Irish Bank - -------------------------------------------------------------------------------- Fills A Niche Anglo Irish Bank is one of the only true niche banking franchises in Europe. Specializing in middle-market banking, Anglo Irish Bank provides corporate lending, commercial mortgages and structured finance arrangements to corporations, partnerships and high net worth clients in Ireland and the UK. A robust lending environment and strong asset quality helped boost the return 125% in 2003 for Columbia Acorn International. Trading at just 11.8-times 2004's earnings with a consistent 30% return on equity and above average earnings growth, we believe the stock price still has room to grow. INVESTMENTS IN FOREIGN SECURITIES HAVE SPECIAL RISKS, INCLUDING POLITICAL OR ECONOMIC INSTABILITY, HIGHER COSTS, DIFFERENT REGULATIONS, ACCOUNTING STANDARDS, TRADING PRACTICES AND LEVELS OF INFORMATION, AND CURRENCY EXCHANGE RATE FLUCTUATIONS. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. * LIBERTY ACORN INTERNATIONAL WAS RENAMED COLUMBIA ACORN INTERNATIONAL ON OCTOBER 13, 2003.

Mohn Columbia Acorn USA finished 2003 up 47.13%, performing in line with the Russell 2000's 47.25% gain. During the fourth quarter, the Fund gained 13.57% vs. a 14.52% gain for the benchmark. Small caps dominated large caps in 2003. The S&P 500, up 28.69%, had a good year but did not come close to reaching small-cap returns. Technology stocks continued to lead the rally. In Columbia Acorn USA, Novell and Micros Systems were among the top five moneymakers in the Fund for the year and the quarter. Novell, up 97% for the quarter and 215% for the year, is highlighted in the box below. Micros had a 93% annual gain and 27% rise in the quarter. After years of waiting, hotels are finally starting to upgrade their computer systems. Micros has been benefiting from this initiative with revenue growth in its hotel and restaurant integration software up nearly 20%. In the financial sector, AmeriCredit and World Acceptance posted top gains. Auto lender AmeriCredit was up 104% for the year and 55% in the fourth quarter. Credit loss reports showed that for the first time in 27 months AmeriCredit had a year-over-year drop in losses in November. Personal lender World Acceptance increased 162% in the year and 47% in the quarter largely due to the strengthening economy. Freight forwarder Hub Group also bounced back with the economy, up an impressive 349% for the year and 98% for the quarter. Aspect Communications was another big percentage winner, up 310% for the year and 89% in the quarter. See Page 4 for more on this stock. The notable poor performer was First Health Group, down 20% in the year and 26% in the quarter. First Health's competition aggressively lowered prices during the year. Home health care service provider Lincare Holdings also fell as the government moved to cut oxygen reimbursement rates, a major source of revenue for Lincare Holdings. Disappointing sales marked down stock prices for retailers Gadzooks and Abercrombie & Fitch in the quarter and for the year. What a difference a year makes. Last year, all areas of the market - small, mid, large - ended the year down in double digits. This year, small-cap gains neared 50%, mid caps cleared 35% and large caps came in at about 30% (See Page 1 for index returns). So, what's next? Small caps did so well in 2003 that there is some concern that they are getting overpriced. We still believe that small caps are in for a very long period of outperformance. As for valuations, we have a list of stocks that we believe are attractive to buy at current levels. Today that list is smaller than it was six months ago but we believe there continue to be small-cap stocks to buy at good prices. /s/ Robert A. Mohn Robert A. Mohn LEAD PORTFOLIO MANAGER Novell Competes - -------------------------------------------------------------------------------- Novell, the leading provider of network printer, directory, and file services, is up against a formidable competitor, Microsoft. But Novell isn't backing down. The company has invested capital and leveraged existing knowledge to go after new markets. Security Identity Management and Linux are two fast-growing markets in which Novell has been building a name for itself. Columbia Wanger Asset Management's technology analyst Ben Andrews purchased Novell under the assumption that at least one of these markets would drive Novell's revenue and earnings over the next one to two years. Wall Street has become aware of Novell's push into Linux and has doubled the price of its shares. Novell's bottom line pay out has yet to come, but we believe it is on the right track. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. * LIBERTY ACORN USA WAS RENAMED COLUMBIA ACORN USA ON OCTOBER 13, 2003.

Olson After three years of posting dreary results, the international markets rose sharply in 2003. Columbia Acorn International Select finished the year up 41.79% vs. a 49.65% gain for the benchmark Citigroup World ex-US Cap Range $2-10B Index and a 38.59% return for the large-cap MSCI EAFE Index. In the fourth quarter, the Fund gained 16.92%, outperforming the benchmark return of 15.81% and nearing the MSCI EAFE gain of 17.08%. Market interest in Japan and in more speculative stocks in general cooled in the fourth quarter, benefiting the Fund's relative return. But the Fund's more conservative stance toward Japan and higher-risk stocks dampened annual performance. Still, an annual return of nearly 42%,achieved without speculative maneuvering, should delight most shareholders. For the quarter, three of the four biggest winners in the Fund were banks offering niche services. Anglo Irish Bank, the Fund's largest holding, finished up 48% in the quarter. The corporate lending environment in the United Kingdom remains robust and Anglo Irish Bank continued to benefit. For the year, shares were up over 125%. Another winner in Columbia Acorn International Select was Den Norske Bank, a full-service commercial bank in Norway. Shares finished up 39% in the quarter and up 52% for the year. Ireland's Depfa Bank, a provider of public-sector financing, finished the quarter up 31%. For the year, shares were up 156%. The Fund's worst stocks for the quarter included Parmalat, the big dairy producer in Italy. Shares fell 55% when it was revealed that a huge cash reserve on its books was falsified. We limited the Fund's downside risk early on by halving its position in the stock when concerns first surfaced, selling those shares for a slight gain. We sold out of the Fund's remaining position shortly before the company went bankrupt. Another stock dragging down performance this quarter was Terumo, a maker of pharmaceuticals and medical supplies in Japan. Continued cuts in drug reimbursements and a steady decline in the number of new drugs coming to market slowed growth in pharmaceutical sales. The share price fell 3% during the quarter and we sold the Fund's position in the stock. /s/ Todd M. Narter /s/ Christopher J. Olson Todd M. Narter Christopher J. Olson CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER More Than The Name - -------------------------------------------------------------------------------- You Know The Swatch brand name conjures up an image of a colorful, plastic watch that was a must-have for trendy teens in the '80s. While the Swatch watch continues to attract buyers, the earnings growth for this Swiss watchmaker is coming from its higher-end brands Omega and Brequet. Demand for the pricier lines is increasing in China and in the rest of the Asia Pacific region. We added the stock to Columbia Acorn International Select because we believe Swatch has a solid brand and is a low cost producer. Valuations are also good. After appreciating 27% in the quarter, the shares still sell at a discount to its peers. MID-CAP STOCKS TEND TO BE MORE VOLATILE AND MAY BE LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES.

Park Columbia Acorn Select returned 4.97% during the fourth quarter, behind the benchmark S&P MidCap 400's 13.19% return and the S&P 500's 12.18% gain. For 2003, the Fund was up 30.61%, trailing the S&P MidCap 400's 35.62% return but beating the S&P 500's 28.69% gain. While we are pleased with the Fund's absolute result, we are disappointed that Columbia Acorn Select underper-formed since it was leading its primary benchmark through the first three quarters of the year. Electronic Arts gained 97% in 2003, as sales and earnings consistently beat expectations. Guidant, the Fund's largest position, returned 92% as investors came to appreciate the company's fast growing defibrillator business as well as its potential growth making drug-eluting stents. (A stent is a little wire-mesh tube that keeps an artery open after an angioplasty procedure.) On the downside, First Health Group, one of the Fund's biggest positions, fell 20% for the year as the company lowered its sales and earnings for 2004 due to increased competition in the managed-care industry. While obviously disappointed, we believe the long-term outlook remains sound and we have added to the Fund's position. Most other losses for the year were relatively small in position size or percentages. In fact, all losses combined contributed to just a 3.16% drop for the Fund in 2003. Perhaps our biggest detractor was the conservative nature of Columbia Acorn Select; only five of the Fund's stocks were up 70% or more. While the market has rewarded the Fund's more conservative stance in the past, highly speculative stocks had the most impressive gains in 2003 and Columbia Acorn Select did not keep pace. Furthermore, as the market has bounced back, we have seen few opportunities to buy such stocks at prices that fairly compensate us for the risks incurred. I am justifiably proud of the terrific efforts put forth by our investment team in 2003. My thanks to Ralph Wanger, Chuck McQuaid, Rob Mohn, Ben Andrews, Susie Hultquist, Harold Lichtenstein, Grant McKay, Rob Chalupnik, Todd Griesbach, David Frank, and John Emerson for their invaluable contributions. I am also grateful to Shelley Maish and Mike Olah for providing Herculean efforts in trading throughout the year. Finally, thank you for your continued support as a Columbia Acorn Select shareholder. /s/ John H. Park John H. Park LEAD PORTFOLIO MANAGER Weight Watchers -- - -------------------------------------------------------------------------------- A Winning Loser The first question you ask a successful dieter is, "How did you lose the weight?" This marketing has contributed to Weight Watchers' unique business model by which its customers actually perpetuate the success of the business. With over 40 years in the business, the Weight Watchers' brand has become synonymous with healthy weight loss. Demand is more robust than ever with obesity rates at an all time high both domestically and in international markets. The company generates significant free cash flow due to fat profit margins and slim capital expenditure requirements, which it has been using to acquire franchises, pay down debt and repurchase stock -- all accretive to earnings. The stock has been under pressure recently as attendance growth has moderated due to the current popularity of the Atkins/high protein diet. History has shown us though that diet fads come and go, similar to excess weight, and we believe the sensibility of the Weight Watchers' program is one that dieters will return to, as will investors to the stock.

McQuaid Photo of Harvery Hirschhorn The Columbia Thermostat Fund completed its first full year of operations in 2003. The Fund rebal- ances between five stock funds and three bond funds according to a simple mechanical rule, quite like the way your home thermostat keeps the room temperature steady. The logical construction of the Fund appealed to many people, so assets at year-end were nearly $128 million, what we believe to be a very good number for a start-up fund. Investment performance for the Fund was satisfactory, up 7.34% in the fourth quarter and 19.79% for the year (see Page 1 for index comparisons).

The Fund's equity portfolio had a 29.40% return for the year, and the fixed income piece was up 7.73%. Thermostat's equity funds were 50% in small-cap, mid-cap and value funds, which was an overweighting in these categories vs. the entire market; this was a good idea in 2003, as these funds outperformed the large-company index as measured by the S&P 500 Index. The Fund's rebalancing system added some moderate value, but as the year unfolded, a high equity weighting throughout the year would have worked out better. The Thermostat system is likely to produce its best results in a market with lots of up-and-down moves. In 2003, the last 10 months of the year featured a steady uptrend for stocks, so shareholders would have done better by having all their money in an equity fund such as Columbia Acorn Fund. Of course, one cannot know that at the beginning of the year, which is why Columbia Thermostat makes sense for conservative investors. /s/ Ralph Wanger /s/ Charles P. McQuaid Ralph Wanger Charles P. McQuaid CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER /s/ Harvery Hirschhorn Harvery Hirschhorn CO-PORTFOLIO MANAGER THE VALUE OF AN INVESTMENT IN THE FUND IS BASED PRIMARILY ON THE PERFORMANCE OF THE UNDERLYING PORTFOLIO FUNDS AND THE ALLOCATION OF THE FUND'S ASSETS AMONG THEM. AN INVESTMENT IN THE UNDERLYING FUNDS MAY PRESENT CERTAIN RISKS, INCLUDING STOCK MARKET FLUCTUATIONS THAT OCCUR IN RESPONSE TO ECONOMIC AND BUSINESS DEVELOPMENTS; AND A GREATER DEGREE OF SOCIAL, POLITICAL AND ECONOMIC VOLATILITY ASSOCIATED WITH INTERNATIONAL INVESTING. INVESTING IN SMALL-AND MID-CAP STOCKS MAY PRESENT SPECIAL RISKS INCLUDING POSSIBLE ILLIQUIDITY AND GREATER PRICE VOLATILITY THAN STOCKS OF LARGER, MORE ESTABLISHED COMPANIES. CHANGES IN INTEREST RATES AND CHANGES IN THE FINANCIAL STRENGTH OF ISSUERS OF LOWER-RATED BONDS MAY ALSO AFFECT UNDERLYING FUND PERFORMANCE. THE FUND IS ALSO SUBJECT TO THE RISK THAT THE INVESTMENT ADVISER'S DECISIONS REGARDING ASSET CLASSES AND PORTFOLIO FUNDS WILL NOT ANTICIPATE MARKET TRENDS SUCCESSFULLY, RESULTING IN A FAILURE TO PRESERVE CAPITAL OR LOWER TOTAL RETURN. IN ADDITION, THE FUND MAY BUY AND SELL SHARES OF THE PORTFOLIO FUNDS FREQUENTLY. THIS MAY RESULT IN HIGHER TRANSACTION COSTS AND ADDITIONAL TAX LIABILITY. THIS IS NOT AN OFFER OF THE SHARES OF ANY OTHER MUTUAL FUND MENTIONED HEREIN. 1-800-922-6769 14 Columbia Thermostat Fund >At a Glance Ticker Symbol: COTZX PRETAX AND AFTER-TAX AVERAGE ANNUAL TOTAL RETURNS (CLASS Z) >through December 31, 2003 1 YEAR LIFE OF FUND - ------------------------------------------------------------ Returns before taxes 19.79% 19.01% - ------------------------------------------------------------ Returns after taxes on distributions 19.26 18.59 - ------------------------------------------------------------ Returns after taxes on distribu- tions and sale of fund shares 12.87 15.97 - ------------------------------------------------------------ S&P 500 (pretax) 28.69 29.59 - ------------------------------------------------------------ Lehman U.S. Credit Intermediate Bond Index (pretax) 6.91 7.95 - ------------------------------------------------------------ Lehman U.S. Govt.

See accompanying notes to financial statements. 1-800-922-6769 58-59 Spread Columbia Acorn Family of Funds >Notes to Financial Statements 1. Nature of Operations Columbia Acorn Fund, Columbia Acorn International, Columbia Acorn USA, Columbia Acorn International Select and Columbia Acorn Select (the "Funds") are series of Columbia Acorn Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of each Fund is to seek long-term growth of capital. The Funds may issue an unlimited number of shares. The Funds offer four classes of shares: Class A, Class B, Class C and Class Z. Class A shares are sold with a front-end sales charge. A contingent deferred sales charge ("CDSC") is assessed to Class A shares purchased without an initial sales charge on redemptions made within eighteen months on an original purchase of $1 million to $25 million. Class B shares are subject to a contingent deferred sales charge. Class B shares will convert to Class A shares in three, four or eight years after purchase, depending on the program under which shares are purchased. Class C shares are subject to a contingent deferred sales charge on redemptions made 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. Generally, you may exchange your Class Z or Class A shares of the Fund for shares of another fund at no additional charge. However, if you exchange Class Z shares of Columbia Acorn International or Columbia Acorn International Select that you have owned 60 days or less for Class Z shares of a fund distributed by Columbia Funds Distributor, Inc., that does not have a redemption fee (including Columbia Acorn Fund, Columbia Acorn USA and Columbia Acorn Select), the Fund will charge you a redemption fee of 2% of the redemption proceeds. Exchanges between Columbia Acorn International and Columbia Acorn International Select (or a fund distributed by Columbia Funds Distributor, Inc. that has a redemption fee) will not be subject to the 2% redemption fee. In addition, if you redeem shares of Columbia Acorn International or Columbia Acorn International Select that you have owned 60 days or less, the Fund will charge you a redemption fee of 2% of redemption proceeds, with certain exceptions. See "Fund Policy on Trading of Fund Shares and Redemption Fees" as disclosed within the Funds' prospectus for more information. The financial highlights for Class A, Class B and Class C shares are presented in a separate annual report. The annual financial statements for the Columbia Thermostat Fund, another Fund of the Trust, begin on page 67 of this report. Effective October 13, 2003, the Funds changed their name from Liberty Acorn Fund to Columbia Acorn Fund, Liberty Acorn International to Columbia Acorn International, Liberty Acorn USA to Columbia Acorn USA, Liberty Acorn Foreign Forty to Columbia Acorn International Select and Liberty Acorn Twenty to Columbia Acorn Select. Also on that date, the Trust changed its name from Liberty Acorn Trust to Columbia Acorn Trust. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are borne pro rata on the basis of the relative net assets of all classes, except each class bears certain expenses unique to that class such as distribution services, transfer agent, and certain other class specific expenses. Differences in class expenses may result in payment of different dividend distributions for each class. All the share classes of the Trust have equal rights with respect to voting subject to class specific arrangements. On July 26, 2002, Columbia Acorn USA acquired all of the net assets of the Stein Roe Small Company Growth Fund ("Stein Roe Fund") pursuant to a plan of reorganization approved by the Stein Roe Fund shareholders on June 28, 2002. The acquisition was accomplished by a tax-free exchange of 1,139,488 shares of the Stein Roe Fund (valued at $10,096,640) for 726,123 shares of Columbia Acorn USA. The net assets of the Stein Roe Fund were combined with the net assets of Columbia Acorn USA on the acquisition date and included $3,125,202 of unrealized depreciation on investment. The aggregate net assets of Columbia Acorn USA immediately before and after acquisition were $306,945,066 and $317,041,706, respectively. 2. Significant Accounting Policies >Security valuation Investments are stated at fair value. Securities traded on securities exchanges or in over-the-counter markets in which transaction prices are reported are valued at the last sales price at the time of valuation. If a security is traded principally on the Nasdaq Stock Market Inc., the SEC-approved Nasdaq Official Closing Price will be applied. Securities for which there are no reported sales on the valuation date are valued at the latest bid quotation. Money market instruments having a maturity of 60 days or less from the valuation date are valued on an amortized cost basis, which approximates fair value. Securities for which 1-800-922-6769 60 quotations are not available are valued at a fair value as determined in good faith by the Board of Trustees. >Repurchase agreements The Funds may engage in repurchase agreement transactions. The Funds, through their custodians, receive delivery of underlying securities collateralizing repurchase agreements. The Funds' investment advisor determines that the value of the underlying securities is at all times at least equal to the resale price. In the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. >Foreign currency translations Values of investments denominated in foreign currencies are converted into U.S. dollars using the spot market rate of exchange at the time of valuation. Purchases and sales of investments and dividend and interest income are translated into U.S. dollars using the spot market rate of exchange prevailing on the respective dates of such transactions. The gain or loss resulting from changes in foreign exchange rates is included with net realized and unrealized gain or loss from investments, as appropriate. >Security transactions and investment income Security transactions are accounted for on the trade date (date the order to buy or sell is executed) and dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities are recorded as soon as the information is available to the Funds. Interest income is recorded on the accrual basis and includes amortization of discounts on money market instruments and long-term debt instruments when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. Awards from class action litigation may be recorded as a reduction of cost. 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. Results of operations for the year reflect a change in estimate of these components using more current tax reporting received from REIT investments. The change in estimate had no impact on each of the Fund's net assets. >Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. >Financial instruments Each Fund may purchase or sell exchange-traded financial futures contracts, which are contracts that obligate that Fund to make or take delivery of a financial instrument or the cash value of a securities index at a specified future date at a specified price. The Funds enter into such contracts to hedge a portion of their portfolio. Gains and losses are reflected as "Net Realized Gain (Loss) on Futures" in the Statements of Operations. Additionally, each Fund, except for Columbia Acorn USA and Columbia Acorn Select, may engage in portfolio hedging with respect to changes in foreign currency exchange rates by entering into forward foreign currency contracts to purchase or sell foreign currencies. The Statements of Operations reflect gains and losses as realized for closed forward foreign currency contracts and unrealized for open contracts. The Funds bear the market risk that arises from changes in the value of financial instruments and securities indices (futures contracts) or from changes in foreign currency rates (forward foreign currency contracts) and the credit risk should a counterparty fail to perform under such contracts. None of the Funds entered into any futures contracts or forward foreign currency contracts during the year ended December 31, 2003. >Fund share valuation Fund shares are sold and redeemed on a continuing basis at net asset value. Net asset value per share is determined daily as of the close of trading on the New York Stock Exchange on each day the Exchange is open for trading. All income, expenses (other than the Class A, Class B and Class C 12b-1 and distribution fees, and Class A, Class B, Class C and Class Z shares Transfer Agent fees) and realized and unrealized gains (losses) of a fund are allocated to each class proportionately on a daily basis for purposes of determining the net asset value of each class. Redemption fees are allocated to paid-in-capital of each class proportionately for the purposes of determining net asset value of each class. >Custody fees Custody fees are reduced based on each Fund's cash balances maintained with the custodian. The amount is disclosed as a reduction of total expenses in the Statement of Operations. 1-800-922-6769 61 Columbia Acorn Family of Funds >Notes to Financial Statements continued >Federal income taxes The Funds have complied with the special provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distribute all their taxable income, as well as any net realized gain on sales of investments and foreign currency transactions reportable for federal income tax purposes. Accordingly, the Fund paid no federal income taxes and no federal income tax provision was required. >Distributions to Shareholders Distributions to shareholders are recorded on the ex-date. 3. Federal Tax Information Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences are primarily due to differing treatments for deferral of losses from wash sales, straddle deferrals, mark-to-market on futures contracts, current year distribution payable, foreign currency transactions, net operating losses, passive foreign investment companies, capital loss carryforwards, post-October losses and non-deductible expenses. Reclassifications are made to the Funds' capital accounts to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2003, permanent items identified and reclassified among the components of net assets are as follows: UNDISTRIBUTED NET INVESTMENT INCOME (ACCUMULATED NET ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN UNREALIZED LOSS) GAIN (LOSS) CAPITAL APPRECIATION - ----------------------------------------------------------------------------- (IN THOUSANDS) Columbia Acorn Fund $ 13,265 $ (13,067) $ (607) $ 409 Columbia Acorn International 1,034 (7,045) -- 6,011 Columbia Acorn USA 4,550 3,217 (7,767) -- Columbia Acorn International Select 20 (20) -- -- Columbia Acorn Select 4,409 (4,146) (263) -- Net investment income, net realized gains (losses) and net assets were not affected by this reclassification.

Transactions with Affiliates Effective October 13, 2003, the Fund's investment advisor changed its name from Liberty Wanger Asset Management, L.P. to Columbia Wanger Asset Management, L.P. ("Columbia WAM"). Columbia WAM, a wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a wholly-owned subsidiary of Fleet National Bank, which in turn is a wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"), furnishes continuing investment supervision to each Fund and is responsible for the overall management of the Funds' business affairs. Under the Funds' investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below for each fund.

Columbia WAM also provides administrative services to each Fund at an annual rate of .05% of average daily net assets. Effective October 13, 2003, Liberty Funds Distributor, Inc. changed its name to Columbia Funds Distributor, Inc. (the Distributor). The Distributor, an indirect subsidiary of Fleet, is each Fund's principal underwriter and receives no compensation on the sale of Class Z shares. Each Fund has adopted a 12b-1 plan which requires it to pay the Distributor a service and distribution fee on the net assets attributable to Class A, Class B and Class C shares. Effective October 13, 2003, Liberty Funds Services, Inc. changed its name to Columbia Funds Services, Inc. (the "Transfer Agent"). The Transfer Agent, an affiliate of the investment advisor, provides shareholder services to the Funds and receives reimbursement for out-of-pocket expenses. Certain officers and trustees of the Trust are also officers of Columbia WAM. The Trust makes no direct payments to its officers or trustees who are affiliated with Columbia WAM.

Under that plan, a trustee may elect to defer all or a portion of his or her compensation. Amounts deferred are retained by the Trust and represent an unfunded obligation of the Trust. The value of amounts deferred is determined by reference to the change in value of Class Z shares of one or more series of the Trust or a money market fund as specified by the trustee. Benefits under the deferred compensation plan are payable upon retirement. During the year ended December 31, 2003, the Funds engaged in purchase and sale transactions with funds that have a common investment adviser (or affiliated investment advisers), common Directors/Trustees, and/or common Officers.

Legal Proceedings The Securities and Exchange Commission (the "SEC"), the New York Attorney General and various other regulatory authorities are investigating late trading and market timing in mutual fund shares, and have sent information requests and subpoenas to certain affiliates of Columbia Management Group, Inc. ("CMG") (collectively, "Columbia"). These affiliates include the Distributor, Columbia Management Advisors, Inc. ("CMA"), and Columbia Wanger Asset Management, L.P. ("Columbia WAM"). CMA is the adviser to the Columbia Family of Funds, but is not the adviser to the Columbia Acorn Family of Funds. Columbia has not uncovered any instances where Columbia entities were knowingly involved in late trading of mutual fund shares. Columbia has identified a limited number of investors who had informal arrangements for trading shares of various funds managed by subsidiaries of CMG between 1998 and 2003. A majority of the transactions in connection with these arrangements occurred in one international fund and two domestic funds in the Columbia Family of Funds. A majority of the trading under these arrangements was made by three entities. A substantial majority of the trading had ended by October 2002. None of these arrangements exist today. Information relating to those trading arrangements has been supplied to various regulatory authorities. The SEC staff has issued notices to the effect that it has made a preliminary determination to recommend that the SEC bring civil enforcement actions, including injunctive proceedings, against the Distributor and CMA alleging that they have violated certain provisions of the federal securities laws. Columbia believes that those allegations are based principally on the trading arrangements referred to above. Columbia WAM has not been named in these notices. The Distributor and CMA are engaged in discussions with the SEC staff in an effort to reach a satisfactory resolution of these matters. However, there can be no assurance that such a resolution will be reached. Any potential resolution of these matters may include, but not be limited to, sanctions, financial penalties, damages or injunctions regarding the Distributor or CMA, and structural changes in the conduct of their business. Although Columbia does not believe that these regulatory developments or their resolution will have a material adverse effect on the Funds, or on the ability of the Distributor or Columbia WAM to provide services to the Funds, there can be no assurance that these matters or any publicity relating to these matters or other developments resulting from them will not adversely effect sales or redemptions of Fund shares or otherwise effect the Funds. Columbia Acorn Trust (the "Trust") and Columbia WAM are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in Columbia Acorn International Fund ("International Fund") for a period of more than 14 days during the five years prior to the filing of the lawsuit. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. The lawsuit alleges, in summary, that the Trust and Columbia WAM exposed International Fund shareholders to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of International Fund's securities had occurred after foreign markets had closed but before the calculation of the Fund's net asset value ("NAV"); (b) failing to implement International Fund's portfolio valuation and share pricing policies and procedures; (c) allowing portfolio valuation and share policies and procedures that benefited market timers at the expense of long-term shareholders; and (d) failing to know and implement applicable rules and regulations concerning the calculation of NAV. The Trust and Columbia WAM also are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in International Fund for a period of more than 14 days, without any stated limitation on the duration of the class period. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. This suit contains allegations and counts similar to those described above, and also includes an additional count under Section 36(a) of the Investment Company Act of 1940. The Trust, on behalf of International Fund, and Columbia WAM intend to defend both suits vigorously. The Trust does not believe that the pending actions will have a material adverse affect on the financial statements of any Fund, and Columbia WAM does not believe that the pending actions will have a material adverse affect on its ability to perform under its contracts with the Funds. 1-800-922-6769 65 Columbia Acorn Family of Funds >Unaudited Information FEDERAL INCOME TAX INFORMATION: COLUMBIA ACORN FUND For the fiscal year ended December 31, 2003, the Fund designates long-term capital gains of $24,122.

See accompanying notes to financial statements. 1-800-922-6769 72 Columbia Thermostat Fund >Notes to Financial Statements 1. Nature of Operations Columbia Thermostat Fund (the "Fund"), a series of Columbia Acorn Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust, commenced operations September 25, 2002. The Fund may issue an unlimited number of shares. The Fund currently offers four classes of shares: Class A, Class B, Class C and Class Z. On October 13, 2003, Class D was redesignated Class C. Class A shares are sold with a front-end sales charge.A contingent deferred sales charge may be assessed to Class A shares purchased without an initial sales charge on redemptions made within eighteen months on an original purchase of $1 million to $25 million. Class B shares are subject to a contingent deferred sales charge. Class B shares will convert to Class A shares in three, four or eight years after purchase, depending on the program under which shares are purchased. Class C shares are subject to a contingent deferred sales charge on redemptions made 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. The financial highlights for Class A, Class B and Class C shares are presented in a separate annual report. The annual report for the other series of the Trust is also included in this report. The investment objective of the Fund is to provide long-term total return. The Fund pursues its investment objective by investing in shares of other mutual funds. As a `fund of funds', under normal circumstances, the Fund allocates at least 95% of its net assets among a selected group of stock and bond mutual funds (the "Portfolio Funds") according to the current level of the Standard & Poor's 500 Stock Index in relation to predetermined ranges set by the Fund's investment adviser. As of December 31, 2003, the Fund invested in five stock Portfolio Funds (Columbia Acorn Fund, Columbia Acorn Select Fund, Columbia Growth & Income Fund, Columbia Mid Cap Value Fund, Columbia Growth Stock Fund) and three bond Portfolio Funds (Columbia Federal Securities Fund, Columbia Intermediate Bond Fund and Columbia High Yield Fund). The Fund may also invest up to 5% of its net assets plus any cash received that day in cash, repurchase agreements, high quality short-term paper and government securities. 2. Significant Accounting Policies >Security valuation Investments in Portfolio Funds are valued at their net asset value as reported by the underlying funds. High quality short-term paper and government securities having a maturity of 60 days or less from the valuation date are valued on an amortized cost basis, which approximates fair value. >Repurchase agreements The Fund may engage in repurchase agreement transactions. The Fund, through its custodian, receives delivery of underlying securities collateralizing each repurchase agreement. The Fund's investment advisor determines that the value of the underlying securities is at all times at least equal to the resale price. In the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. >Security transactions and investment income Portfolio Fund transactions are accounted for on the trade date (date the order to buy or sell is executed). Dividend income and realized gain distributions from other funds are recorded on the ex-dividend date. Interest income is recorded on the accrual basis and includes amortization of discounts on money market instruments and short-term debt instruments when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. Awards from class action litigation may be recorded as a reduction of cost. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains. >Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. >Fund share valuation Fund shares are sold and redeemed on a continuing basis at net asset value. Net asset value per share is determined daily as of the close of trading on the New York Stock Exchange on each day the Exchange is open for trading. >Custody fees The custody fees are reduced based on the Fund's cash balance maintained with the custodian. The amount is disclosed as a reduction of total expenses in the Statement of Operations. 73 Columbia Thermostat Fund >Notes to Financial Statements, continued >Federal income taxes The Fund has complied with the special provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distributes all of its taxable income, as well as any net realized gain on sales of Portfolio Fund shares and any distributions of net realized gains received by the Fund from its Portfolio Funds, reportable for federal income tax purposes. Accordingly, the Fund paid no federal income taxes and no federal income tax provision was required. >Distributions to Shareholders Distributions to shareholders are recorded on the ex-date. 3. Federal Tax Information Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences are primarily due to differing treatments of non-deductible expenses. Reclassifications are made to the Fund's capital accounts to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2003, permanent items identified and reclassified among the components of net assets are as follows: OVERDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN INCOME GAIN CAPITAL - ----------------------------------------------------------- (IN THOUSANDS) $ 1 $ (1) $ -- Net investment income, net realized gains (losses) and net assets were not affected by this reclassification. The tax character of distributions paid during the year ended December 31, 2003 was as follows: LONG-TERM TAX ORDINARY CAPITAL RETURN OF INCOME GAINS CAPITAL - ---------------------------------------------------- (IN THOUSANDS) $ 771 $ 10 $ -- As of December 31, 2003, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM UNREALIZED INCOME CAPITAL GAINS APPRECIATION* - ----------------------------------------------------------------- (IN THOUSANDS) $ 197 $ 36 $ 9,253 * The difference between book-basis and tax-basis unrealized appreciation (depreciation), if applicable, is attributable primarily to the tax deferral of losses on wash sales. 4. Transactions with Affiliates Effective October 13, 2003, the Fund's investment advisor changed its name from Liberty Wanger Asset Management, L.P. to Columbia Wanger Asset Management, L.P. ("Columbia WAM"). Columbia WAM, a wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a wholly-owned subsidiary of Fleet National Bank, which in turn is a wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"), furnishes continuing investment supervision to each Fund and is responsible for the overall management of the Fund's business affairs. Under the Funds' investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 0.10% of the Fund's average daily net assets. >Expense Limit Columbia WAM has agreed to voluntarily reimburse the direct operating expenses (exclusive of interest and fees on borrowings and expenses associated with the Fund's investment in other investment companies) exceeding 0.60% of the average annual net assets of the Fund's Class Z shares. Effective August 1, 2003, Columbia WAM has agreed to contractually reimburse the direct operating expenses (exclusive of interest and fees on borrowings and expenses associated with the Fund's investment in other investment companies) exceeding 0.25% of the average annual net assets of the Fund's Class Z shares. Columbia WAM has also contracted to provide administrative services at an annual rate of .05% of the Fund's average daily net assets. Effective October 13, 2003 Liberty Funds Distributor, Inc., changed its name to Columbia Funds Distributor, Inc. (the Distributor). The Distributor, an indirect subsidiary of Fleet, is the Fund's principal underwriter and receives no compensation on the sale of Class Z shares. The Fund has adopted a 12b-1 plan which requires it to pay the Distributor a service and distribution fee on net assets attributable to Class A, Class B and Class C shares. Effective October 13, 2003, Liberty Funds Services, Inc., changed its name to Columbia Funds Services, Inc. (the "Transfer Agent"). The Transfer Agent, an affiliate of the investment advisor, provides shareholder services to the Fund and receives reimbursement for out-of-pocket expenses. 1-800-922-6769 74 Certain officers and trustees of the Trust are also officers of Columbia WAM. The Trust makes no direct payments to its officers and trustees who are affiliated with Columbia WAM. Trustees' fees and expenses for the year ended December 31, 2003, were $270. 5. Borrowing Arrangements The Trust participates in a $150,000,000 credit facility which was entered into to facilitate portfolio liquidity. No amounts have been borrowed under this facility for the year ended December 31, 2003. 6. Investment Transactions The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2003 were: - -------------------------------------------------------------------------------- (IN THOUSANDS) Purchases $ 144,197 Proceeds from sales $ 30,493 ================================================================================ 7. Legal Proceedings The Securities and Exchange Commission (the "SEC"), the New York Attorney General and various other regulatory authorities are investigating late trading and market timing in mutual fund shares, and have sent information requests and subpoenas to certain affiliates of Columbia Management Group, Inc. ("CMG") (collectively, "Columbia"). These affiliates include the Distributor, Columbia Management Advisors, Inc. ("CMA"), and Columbia Wanger Asset Management, L.P. ("Columbia WAM"). CMA is the adviser to the Columbia Family of Funds, but is not the adviser to the Columbia Acorn Family of Funds. Columbia has not uncovered any instances where Columbia entities were knowingly involved in late trading of mutual fund shares. Columbia has identified a limited number of investors who had informal arrangements for trading shares of various funds managed by subsidiaries of CMG between 1998 and 2003. A majority of the transactions in connection with these arrangements occurred in one international fund and two domestic funds in the Columbia Family of Funds. A majority of the trading under these arrangements was made by three entities. A substantial majority of the trading had ended by October 2002. None of these arrangements exist today. Information relating to those trading arrangements has been supplied to various regulatory authorities. The SEC staff has issued notices to the effect that it has made a preliminary determination to recommend that the SEC bring civil enforcement actions, including injunctive proceedings, against the Distributor and CMA alleging that they have violated certain provisions of the federal securities laws. Columbia believes that those allegations are based principally on the trading arrangements referred to above. Columbia WAM has not been named in these notices. The Distributor and CMA are engaged in discussions with the SEC staff in an effort to reach a satisfactory resolution of these matters. However, there can be no assurance that such a resolution will be reached. Any potential resolution of these matters may include, but not be limited to, sanctions, financial penalties, damages or injunctions regarding the Distributor or CMA, and structural changes in the conduct of their business. Although Columbia does not believe that these regulatory developments or their resolution will have a material adverse effect on the Funds, or on the ability of the Distributor or Columbia WAM to provide services to the Funds, there can be no assurance that these matters or any publicity relating to these matters or other developments resulting from them will not adversely effect sales or redemptions of Fund shares or otherwise effect the Funds. Columbia Acorn Trust (the "Trust") and Columbia WAM are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in Columbia Acorn International Fund ("International Fund") for a period of more than 14 days during the five years prior to the filing of the lawsuit. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. The lawsuit alleges, in summary, that the Trust and Columbia WAM exposed International Fund shareholders to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of International Fund's securities had occurred after foreign markets had closed but before the calculation of the Fund's net asset value ("NAV"); (b) failing to implement International Fund's portfolio valuation and share pricing policies and procedures; (c) allowing portfolio valuation and share policies and procedures that benefited market timers at the expense of long-term shareholders; and (d) failing to know and implement applicable rules and regulations concerning the calculation of NAV. 75 Columbia Thermostat Fund >Notes to Financial Statements, continued The Trust and Columbia WAM also are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in International Fund for a period of more than 14 days, without any stated limitation on the duration of the class period. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. This suit contains allegations and counts similar to those described above, and also includes an additional count under Section 36(a) of the Investment Company Act of 1940. The Trust, on behalf of International Fund, and Columbia WAM intend to defend both suits vigorously. The Trust does not believe that the pending actions will have a material adverse affect on the financial statements of any Fund, and Columbia WAM does not believe that the pending actions will have a material adverse affect on its ability to perform under its contracts with the Funds. 1-800-922-6769 76 Columbia Thermostat Fund >Unaudited Information (in thousands) FEDERAL INCOME TAX INFORMATION: For the fiscal year ended December 31, 2003, the Fund designates long-term capital gains of $36. 30.23% of the ordinary income distributed by the Fund, in the year ended December 31, 2003, qualifies for the corporate dividends received deduction. For non-corporate shareholders 30.23%, of the maximum amount allowable under the Jobs and Growth Tax Reconciliation Act of 2003, of income earned by the Fund for the period January 1, 2003 to December 31, 2003 may represent qualified dividend income. Final information will be provided in your 2003 1099-DIV From. 77 Report of Independent Auditors TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF COLUMBIA ACORN TRUST We have audited the accompanying statements of assets and liabilities, including the statements of investments of Columbia Acorn Fund, Columbia Acorn International, Columbia Acorn USA, Columbia Acorn International Select, Columbia Acorn Select and Columbia Thermostat Fund, comprising the Columbia Acorn Trust, as of December 31, 2003, the related statements of operations, changes in net assets, and the financial highlights for the periods indicated therein. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of investments owned as of December 31, 2003, by correspondence with the custodian and brokers or other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds of the Columbia Acorn Trust as of December 31, 2003, the results of their operations and changes in their net assets and financial highlights for the periods indicated therein, in conformity with accounting principles generally accepted in the United States. /s/ Ernst & Young LLP Chicago, Illinois February 6, 2004 1-800-922-6769 78 Columbia Acorn Family of Funds Class Z Share Information MINIMUM INITIAL INVESTMENT IN COLUMBIA ACORN INTERNATIONAL, COLUMBIA ACORN INTERNATIONAL SELECT, COLUMBIA ACORN SELECT, COLUMBIA THERMOSTAT FUND $ 1,000 $ 1,000 FOR AN IRA MINIMUM INITIAL INVESTMENT IN COLUMBIA ACORN FUND AND COLUMBIA ACORN USA $ 50,000 MINIMUM SUBSEQUENT INVESTMENT $ 50 EXCHANGE FEE NONE COLUMBIA ACORN FUND ACRNX Management Fee 0.67% 12b-1 Fee None Other Expenses 0.13% -------- Expense Ratio 0.80% COLUMBIA ACORN INTERNATIONAL ACINX Management Fee 0.84% 12b-1 Fee None Other Expenses 0.21% -------- Expense Ratio 1.05% COLUMBIA ACORN USA AUSAX Management Fee 0.92% 12b-1 Fee None Other Expenses 0.19% -------- Expense Ratio 1.11% COLUMBIA ACORN INTERNATIONAL SELECT ACFFX Management Fee 0.95% 12b-1 Fee None Other Expenses 0.50% -------- Net Expense Ratio 1.45% COLUMBIA ACORN SELECT ACTWX Management Fee 0.90% 12b-1 Fee None Other Expenses 0.22% -------- Expense Ratio 1.12% COLUMBIA THERMOSTAT FUND COTZX Management Fee 0.10% 12b-1 Fee None Other Expenses 0.28% -------- Net Expense Ratio 0.38% Fees and expenses are for the year ended December 31, 2003 and for Columbia Acorn International Select and Columbia Thermostat Fund include the effect of Columbia Wanger Asset Management's undertaking to reimburse those funds for any ordinary operating expenses, net of custody fees paid indirectly, exceeding 1.45% and 0.25% of their average net assets, respectively.

The expense limitation for Columbia Acorn International Select is voluntary and can be terminated by either the Fund or Columbia Wanger Asset Management, L.P. on 30 days' notice. 79 BOARD OF TRUSTEES AND MANAGEMENT OF COLUMBIA ACORN FUNDS The board of trustees serve indefinite terms of unlimited duration provided that a majority of trustees always has been elected by shareholders. The trustees appoint their own successors, provided that at least two-thirds of the trustees, after such appointment, have been elected by shareholders. Shareholders may remove a trustee, with or without cause, upon the vote of two-thirds of Acorn's outstanding shares at any meeting called for that purpose. A trustee may be removed, with or without cause, upon the vote of a majority of the trustees. The names of the trustees and officers of Acorn, the date each was first elected or appointed to office, their principal business occupations and other directorships they have held during at least the last five years, are shown below.

PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. Returns and value of an investment will vary, resulting in a gain or loss on sale. All results shown assume reinvestment of distributions. The "with sales charge" returns include the maximum 5.75% sales charge for Class A shares, the appropriate Class B contingent deferred sales charge for the holding period after purchase as follows: through first year--5%, second year--4%, third year--3%, fourth year--3%, fifth year--2%, sixth year--1%, thereafter--0%; and the Class C contingent deferred sales charge of 1% for the first year only. Performance of the different share classes will vary based on differences in sales charges and fees associated with each class. Performance results reflect any voluntary waivers or reimbursements of Fund expenses by the Advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. Class A, B and C share (newer class shares) performance for all funds 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 new class shares were launched October 16, 2000 for the five Columbia Acorn funds and March 3, 2003 for Columbia Thermostat Fund. These 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 Class A, B and C shares would have been lower. 2 >Fund Performance vs. Benchmarks Class A shares, without sales charge, Average Annual Total Returns through 12/31/03+ 4TH* 1 3 5 10 LIFE QUARTER YEAR YEARS YEARS YEARS OF FUND - --------------------------------------------------------------------------------------------- COLUMBIA ACORN FUND (6/10/70) 14.30% 44.85% 9.63% 14.08% 13.37% 16.24% - --------------------------------------------------------------------------------------------- S&P 500 12.18% 28.69% -4.05% -0.57% 11.07% 12.12% - --------------------------------------------------------------------------------------------- Russell 2500 14.43% 45.51% 6.58% 9.40% 11.74% NA - --------------------------------------------------------------------------------------------- Russell 2000 14.52% 47.25% 6.27% 7.13% 9.47% NA - --------------------------------------------------------------------------------------------- Lipper Small-Cap Core Funds Index 14.85% 40.90% 6.83% 9.39% 11.11% NA - --------------------------------------------------------------------------------------------- Lipper Mid-Cap Core Funds Index 13.06% 36.58% 2.38% 7.89% 10.95% NA - --------------------------------------------------------------------------------------------- COLUMBIA ACORN INTERNATIONAL (9/23/92) 17.11% 46.94% -1.26% 6.64% 7.26% 10.91% - --------------------------------------------------------------------------------------------- Citigroup EMI Global ex-US 15.97% 55.02% 7.19% 6.18% 4.74% 6.28% - --------------------------------------------------------------------------------------------- MSCI EAFE 17.08% 38.59% -2.91% -0.05% 4.47% 6.16% - --------------------------------------------------------------------------------------------- Lipper Int'l Small- Cap Funds Index 14.77% 55.10% 5.45% 10.31% NA NA - --------------------------------------------------------------------------------------------- COLUMBIA ACORN USA (9/4/96) 13.40% 46.26% 12.03% 9.47% -- 13.71% - --------------------------------------------------------------------------------------------- Russell 2000 14.52% 47.25% 6.27% 7.13% -- 8.63% - --------------------------------------------------------------------------------------------- Lipper Small-Cap Core Funds Index 14.85% 40.90% 6.83% 9.39% -- 9.90% - --------------------------------------------------------------------------------------------- S&P 500 12.18% 28.69% -4.05% -0.57% -- 9.12% - --------------------------------------------------------------------------------------------- COLUMBIA ACORN INT'L SELECT (11/23/98) 16.91% 41.11% -5.35% 5.94% -- 7.80% - --------------------------------------------------------------------------------------------- Citigroup World ex-US Cap Range $2-10B 15.81% 49.65% 4.73% 5.92% -- 6.48% - --------------------------------------------------------------------------------------------- MSCI EAFE 17.08% 38.59% -2.91% -0.05% -- 0.75% - --------------------------------------------------------------------------------------------- Lipper International Funds Index 15.45% 36.00% -1.85% 2.13% -- 2.51% - --------------------------------------------------------------------------------------------- COLUMBIA ACORN SELECT (11/23/98) 4.81% 29.95% 8.71% 13.14% -- 14.37% - --------------------------------------------------------------------------------------------- S&P MidCap 400 13.19% 35.62% 4.84% 9.21% -- 11.28% - --------------------------------------------------------------------------------------------- Lipper Mid-Cap Growth Index 10.98% 35.42% -8.56% 2.18% -- 4.78% - --------------------------------------------------------------------------------------------- S&P 500 12.18% 28.69% -4.05% -0.57% -- 0.55% - --------------------------------------------------------------------------------------------- COLUMBIA THERMOSTAT FUND (9/25/02) 7.20% 19.43% -- -- -- 18.73% - --------------------------------------------------------------------------------------------- S&P 500 12.18% 28.69% -- -- -- 29.59% - --------------------------------------------------------------------------------------------- Lehman U.S. Credit Intermediate Bond Index 0.40% 6.91% -- -- -- 7.95% - --------------------------------------------------------------------------------------------- Lehman U.S Govt.

Are the investing rules the same for managing small-cap/mid-cap funds and large-cap funds? Here are some of my personal opinions on these questions. We believe some basic principles apply to any stock portfolio. (1) Diversification reduces risk, so own mid-cap stocks (Columbia Acorn Select) and a small-cap fund (Columbia Acorn USA). (2) International stocks add additional beneficial diversification (Columbia Acorn International)1. (3) The market often over-values growth stocks, so pay close attention to valuation. (4) Big winners take years to develop, so think long term. So what are the differences in managing small-, mid- and large-cap funds? Many large-company portfolios are run according to the rules expressed in Charles Ellis's book, WINNING THE LOSER'S GAME. 2 He tells us to play it safe. Start with a portfolio that mirrors the market and try to avoid big losers (fraud such as Enron and WorldCom, overpriced growth such as Cisco at $80 3). One could say he starts with the S&P 500 and reduces it to the Ellis 495 by getting rid of some potential big losers. The WINNING THE LOSER'S GAME strategy may work for a big-company portfolio, but it is not the way I like to run a small-cap fund. Small-cap is a winner's game. You want to be a Barry Bonds or a Sammy Sosa and hit 50 home runs. If you get the homers, you are a hero; you can strike out a lot of times but no one will care very much. As an example, International Game Technology (IGT) has been a great long-term winner for the funds. In the 2003 season, IGT hit a grand slam - - an additional unrealized gain of $175 million!4 Even if you strike out more often than you would like, one big winner more than offsets a half-dozen $10 million losers. Some of our big winners are duly celebrated in the Scarlet A section. The funds had fine results in 2003 due to the success we had in these stocks and many others. Writing about success, however, is less colorful than writing about failure; there are more plays about Nero than about Marcus Aurelius. When it comes to investing, there are only a few ways to fail. You can buy a company that runs into unexpected problems. Sometimes you buy into a speculative company you know is high risk and the company just doesn't make it. The unfortunate speculators who bought Cisco at $80 lost mere hundreds of billions of dollars compared to the more unfortunate speculators gulled by the Enron and WorldCom frauds. Of course bubbles and speculation have a long history. The first overpricing bubble on record was the tulip-mania boom in Holland in 1636. Tulips were a new "high-tech" flower in Europe but the price of strangely colored varieties went way too high, creating a nasty collapse. Tulip-bulb farming today is still important to the Dutch but it is no longer high tech. Farmers can fool you. About 25 years ago, I put some personal money into Maine Sugar. The promoter was a potato processor in Aroostook County, Maine. He believed that the climate and soil there was favorable for growing sugar beets. He floated stock to build a sugar refinery and invited a planeload of New York analysts to come see the sugar beet fields under cultivation. The analysts got on a bus and were driven to a field where the CEO dug up a giant sugar beet. The analysts had never seen such a large sugar beet (most of them had never seen a farm, for that matter). They got back on the bus, and after another ten minutes arrived at another field. The CEO dug up a sugar beet bigger than the first one. The bus continued to another farm field where again an impressive beet was unearthed. When the analysts arrived back in New York, they wrote buy reports based on the great number of farms growing sugar beets. Maine Sugar dissolved a few months later, and the city-boy analysts realized that they had been shown the same field three times in a row. (Columbia Acorn Funds didn't own Maine Sugar). The latest foolish farm fraud is Parmalat, an Italian company in the milk business. (Parma latte, get it?) The Columbia Acorn Funds lost a few million dollars in Parmalat (see Pages 8 and 12). Big banks that did business with Parmalat could lose hundreds of millions of dollars in bad loans. One of the centerpieces of the fraud was a made-up bank deposit of 3.95 billion euros (about $5 billion). The Parmalat officials allegedly handed the auditors a hastily forged document purporting to be the bank's acknowledgement of the deposit. The auditors appear to have accepted the false affidavit without making their own inquiry ("Hey, we are facing a deadline and it's only five billion.") and allowed the company to continue its fraud for a few more months, roping us in. How could we have avoided getting caught? Talking to company management more often probably would have not helped at all; after all, the bank lenders, the bond rating agencies, and auditor were fooled, and they had much freer access to the company's internal records then any outside financial analyst could ever get. One answer would have been to talk to Parmalat's suppliers, in this case the dairy farmers. After the collapse, someone did ("Parma Farmers Had One Rule: Don't Deal With Parmalat," BLOOMBERG NEWS, January 19, 2004). Achille Coelli, director of the Union of Parma Farmers said, "Farmers here won't work with Parmalat. Tanzi [the CEO] never had a good reputation. The company was a slow payer, so only one 1-800-922-6769 4 percent of the milk produced in Parma province was sold to Parmalat." Obvious red flag? Sure. Did any analyst do this check before the collapse? Don't think so. What conclusions do we want to draw from this crying over spilt milk, besides the vaguely comforting notion that not all fraud occurs in the USA? First, a smart crook can fool some of the people all of the time. Second, really star-quality analytic work could help discover frauds sooner, but much of the time that doesn't happen. Third, complete skepticism would have you avoid fraud, but you would avoid the good investments too. An investor must balance skepticism and credulity just as one balances risk/return or growth/value. Fourth, diversification dilutes the negative effect of one bad stock. Since fraud tends to hit you one at a time, it's a strike out, but it doesn't cost you the season. The benefits you get from big winners far outweigh a few losers. 2003 SCARLET A WINNERS HEAP HIGH THE GOLDEN CORN! 5 -- JOHN GREENLEAF WHITTIER Our analysts and portfolio managers deserve a lot of credit for picking exceptional stocks but we do not rely solely on our internal investment prowess. Often we get sage advice from investment pros outside our Chicago office. We honor and thank these individuals by presenting them with the coveted Scarlet A certificate. In 2003, domestic stocks had to increase more than 150% and make more than $40 million to be considered for a Scarlet A. The international stock criteria was a return of at least 100% and a dollar gain of $20 million or more. Our thanks to Greg Jackson of Blum Capital Partners for his help on software company NOVELL. The stock was up 214% in 2003 and brought in a firm-wide gain of over $101 million. Rural cellular service provider WESTERN WIRELESS was up 250% in 2003 and provided a dollar gain of nearly $69 million. Hats off to Thomas Lee of JPMorgan for his help with this 2003 winner. Thomas confirmed our internal analysis that Western Wireless was generating free cash flow and that fears that the company could go bust were unfounded. Natural gas producer ULTRA PETROLEUM, up nearly 150%, brought in a dollar gain of over $50 million. Credit for this idea goes to Barry Sahgal of Brean Murray & Co. While this is Barry's first Scarlet A win, this is not his first contribution to the Columbia Acorn Funds. Barry also brought EVERGREEN RESOURCES to our attention in 1998, a stock that has increased over 270% during the five years we've held it in our funds. A repeat winner tops our international Scarlet A list. Ireland's ANGLO IRISH BANK was up 142% in 2003 and provided a firm-wide dollar gain of nearly $60 million. To David Smith of Davy Stockbrokers in Dublin: Thanks again! Stefan Stalmann of Dresdner Kleinwort Wasserstein in Frankfurt, Germany, earns the Scarlet A for his help with DEPFA BANK. The stock, up 139% with a $22 million gain, provides international public-sector financing. While we had built a position in Depfa Bank before speaking with Stefan, his understanding of the company reinforced our conviction and we remained invested in the stock longer than we might have on his advice, benefiting shareholders. It is noteworthy that Robert Hurkmans, a Dresdner contact in New York, encouraged us to contact Stefan. The best attributes of a good broker are credibility and being selective about providing information and analyst contacts within their own organization. So, to Robert Hurkmans, we offer kudos for darned good brokering. COLUMBIA WAM NEWS John Park has been named director of domestic research for Columbia Wanger Asset Management, L.P.

McQuaid Photo of Robert A. Mohn Photo of John H. Park Columbia Acorn Fund surged 44.85% (Class A shares, without sales charge) in 2003, our fourth best year ever. As shown on Page 3, the Fund matched the Russell 2500, slightly underperformed the Russell 2000, handily beat many peers and substantially outperformed the large-cap S&P 500. During the fourth quarter, Columbia Acorn Fund's 14.30% gain matched small-cap performance measures and moderately beat mid- and large-cap benchmarks. We've previously discussed buying good tech stocks at distressed prices, and also purchasing select telecom and biotech stocks when we believed we were being paid to take risk. Most of these stocks were up a lot, but given improved tech demand, repaired telecom balance sheets, and biotech fundamental progress, we believe additional gains seem plausible for many of the holdings. We constantly review the Fund's portfolio, looking to swap into stocks that we consider more attractive. Aspect Communications, discussed separately on this page, was Columbia Acorn Fund's biggest percentage winner, up 454% during the year. Barcode and wireless ID systems maker Unova jumped 354% on improved earnings, while software provider Novell, technology e-learning company Skillsoft Publishing, and technology staff company Igate Capital each at least doubled. The Fund's biggest loser was First Health Group, down over 20%, as competitors put pricing pressure on the firm. Columbia Acorn Fund's foreign stocks delivered an average 57.81% return for the year. The leading percentage gainer was Korean auto parts maker Hyundai Mobis, which cranked out a 171% gain on better than expected earnings. Anglo Irish Bank, discussed on Page 8, appreciated 125% and was the Fund's largest foreign winner in dollars. We continue to believe that foreign stocks on average are better values than domestic securities, so we have increased the Fund's foreign weighting to 12.7%. We currently don't expect it to exceed 15%. Small caps have outperformed large caps for nearly five years and by most measures small-cap valuations are now close to long-term average valuations relative to large caps. While we continue to find companies that we believe are attractive, the combination of fewer compelling new ideas and more existing stocks approaching sell targets has caused the Board of Trustees to take proactive steps to reduce cash inflows. Existing shareholders can continue to buy shares in Columbia Acorn Fund. The minimum for NEW eligible accounts, however, has been raised to $50,000 and several marketing channels have been closed. Please see our recent prospectus supplement for additional details. We'd like to take this opportunity to officially welcome John Emerson to Columbia Wanger Asset Management's domestic analyst team. John joined us mid-year to cover media stocks. /s/ Charles P. McQuaid /s/ Robert A. Mohn Charles P. McQuaid Robert A. Mohn LEAD PORTFOLIO MANAGER CO-PORTFOLIO MANAGER /s/ John H. Park John H. Park CO-PORTFOLIO MANAGER The Right Call - --------------- Columbia Wanger Asset Management's technology services and software analyst Ben Andrews always believed that technology was driving a revolution in the telecommunications industry. Though telecom-related stocks collapsed from early 2000 to early 2003, consumers worldwide still wanted hand-held devices and broadband connections, while corporations wanted increased productivity and cost savings. Call center software provider Aspect Communications suffered from management, product, and financing transitions, but had a stable customer base that generated plenty of revenue. As the economy improved, Aspect's next generation products started to grow, and the company's financing and management problems were worked out. Aspect became profitable and the stock rose over 450% in 2003. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. INVESTMENTS IN FOREIGN SECURITIES HAVE SPECIAL RISKS, INCLUDING POLITICAL OR ECONOMIC INSTABILITY, HIGHER COSTS, DIFFERENT REGULATIONS, ACCOUNTING STANDARDS, TRADING PRACTICES AND LEVELS OF INFORMATION, AND CURRENCY EXCHANGE RATE FLUCTUATIONS. *LIBERTY ACORN FUND WAS RENAMED COLUMBIA ACORN FUND ON OCTOBER 13, 2003.

The Fund was up 17.11% (Class A shares, without sales charge) for the quarter, outperforming both the 15.97% gain of the Citigroup EMI Global ex-US Index and the 17.08% return of the MSCI EAFE Index. For the year, the Fund's return of 46.94% fell short of the Citigroup EMI Global ex-US return of 55.02% but beat the MSCI EAFE return of 38.59%. Stocks outside the Fund's core strategy, mainly stocks in the basic materials sector, soared during the year, dampening the Fund's return. Even though the Fund didn't beat the benchmark Citigroup EMI Global ex-US Index, the absolute return for the year is the third best in Columbia Acorn International's history. The best stocks in the quarter and year came from a variety of industries. ASE Test, a semiconductor packaging and testing company in Taiwan, rose 72% on a recovery in demand for semiconductors. For the year, the stock was up 271%. Improved sales drove home a 69% fourth quarter gain for South Korean auto parts maker Hyundai Mobis and an annual gain of 197%. Other winners included Global Bio-Chem Technology Group, a maker of corn starch and corn gluten headquartered in Hong Kong, up 64% in the quarter and 137% for the year; United Services Group, a temporary staffing service in the Netherlands, up 57% in the quarter and 114% for 2003; and Anglo Irish Bank, a niche middle-market bank in Ireland and the Fund's largest holding, up 48% in the fourth quarter and 125% for the year. A problem stock for the quarter was Zapf Creation, a toy manufacturer in Germany, down on weakness in its U.S. doll business. The company has made changes to its U.S. sales organization and plans to introduce new products in 2004. We believe these changes should help Zapf regain traction in the important U.S. market. The Fund's small position in Italian dairy producer Parmalat fell 55% in the quarter when it was revealed that a huge cash reserve on its books was falsified. The Fund minimized losses in the stock by halving the position when concerns first surfaced. Laggards for the year included Ireland's Waterford Wedgewood, down 51%. Its highly leveraged position hurt the stock in a year when luxury good purchases, particularly in the household goods sector, were subdued. The stock was also hurt by the weakened U.S. dollar. Singapore's Star Cruises also sank in the annual period, down 40%. The company's heavy reliance on Asian gambling cruises to support its large debt worried investors following the SARS outbreak and the expansion of gambling operations within Asia. We sold the Fund's position in the stock. We are pleased to introduce a new member to Columbia Wanger Asset Management's international analyst team. Kenneth Wooden joined the firm in early December to cover Japanese equities. Ken spent 17 years investing in Japan and is a welcome addition to the team. /s/ P. Zachary Egan /s/ Louis J. Mendes III P. Zachary Egan Louis J. Mendes III CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER Anglo Irish Bank - -------------------------------- Fills A Niche Anglo Irish Bank is one of the only true niche banking franchises in Europe. Specializing in middle-market banking, Anglo Irish Bank provides corporate lending, commercial mortgages and structured finance arrangements to corporations, partnerships and high net worth clients in Ireland and the UK. A robust lending environment and strong asset quality helped boost the return 125% in 2003 for Columbia Acorn International. Trading at just 11.8-times 2004's earnings with a consistent 30% return on equity and above average earnings growth, we believe the stock price still has room to grow. INVESTMENTS IN FOREIGN SECURITIES HAVE SPECIAL RISKS, INCLUDING POLITICAL OR ECONOMIC INSTABILITY, HIGHER COSTS, DIFFERENT REGULATIONS, ACCOUNTING STANDARDS, TRADING PRACTICES AND LEVELS OF INFORMATION, AND CURRENCY EXCHANGE RATE FLUCTUATIONS. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. * LIBERTY ACORN INTERNATIONAL WAS RENAMED COLUMBIA ACORN INTERNATIONAL ON OCTOBER 13, 2003.

THE VALUE OF A $10,000 INVESTMENT IN COLUMBIA ACORN INTERNATIONAL >December 31, 1993 through December 31, 2003 Illustration is based on a hypothetical $10,000 investment in Class A shares of the Fund, which includes the 5.75% maximum initial sales charge. The Fund commenced operations on 9/23/1992, but until 10/16/2000, offered only the shares that are now designated Class Z shares. The historical performance of Class A, B and C shares (newer class shares) for the period prior to 10/16/2000 is based on the performance of Class Z shares. The Class A, B and C share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between Class A, B, and C and Class Z. Had the expense differential been reflected, the returns for periods prior to the inception of the newer class shares would have been lower. Performance may reflect any voluntary waiver or reimbursement of Fund expenses by the Advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower.

Mohn Columbia Acorn USA finished 2003 up 46.26% (Class A shares, without sales charge), performing in line with the Russell 2000's 47.25% gain. During the fourth quarter, the Fund gained 13.40% vs. a 14.52% gain for the benchmark. Small caps dominated large caps in 2003. The S&P 500, up 28.69%, had a good year but did not come close to reaching small-cap returns. Technology stocks continued to lead the rally. In Columbia Acorn USA, Novell and Micros Systems were among the top five moneymakers in the Fund for the year and the quarter. Novell, up 97% for the quarter and 215% for the year, is highlighted in the box below. Micros had a 93% annual gain and 27% rise in the quarter. After years of waiting, hotels are finally starting to upgrade their computer systems. Micros has been benefiting from this initiative with revenue growth in its hotel and restaurant integration software up nearly 20%. In the financial sector, AmeriCredit and World Acceptance posted top gains. Auto lender AmeriCredit was up 104% for the year and 55% in the fourth quarter. Credit loss reports showed that for the first time in 27 months AmeriCredit had a year-over-year drop in losses in November. Personal lender World Acceptance increased 162% in the year and 47% in the quarter largely due to the strengthening economy. Freight forwarder Hub Group also bounced back with the economy, up an impressive 349% for the year and 98% for the quarter. Aspect Communications was another big percentage winner, up 310% for the year and 89% in the quarter. See Page 6 for more on this stock. The notable poor performer was First Health Group, down 20% in the year and 26% in the quarter. First Health's competition aggressively lowered prices during the year. Home health care service provider Lincare Holdings also fell as the government moved to cut oxygen reimbursement rates, a major source of revenue for Lincare Holdings. Disappointing sales marked down stock prices for retailers Gadzooks and Abercrombie & Fitch in the quarter and for the year. What a difference a year makes. Last year, all areas of the market - small, mid, large - ended the year down in double digits. This year, small-cap gains neared 50%, mid caps cleared 35% and large caps came in at about 30% (See Page 3 for index returns). So, what's next? Small caps did so well in 2003 that there is some concern that they are getting overpriced. We still believe that small caps are in for a very long period of outperformance. As for valuations, we have a list of stocks that we believe are attractive to buy at current levels. Today that list is smaller than it was six months ago but we believe there continue to be small-cap stocks to buy at good prices. /s/ Robert A. Mohn Robert A. Mohn LEAD PORTFOLIO MANAGER Novell Competes - ----------------- Novell, the leading provider of network printer, directory, and file services, is up against a formidable competitor, Microsoft. But Novell isn't backing down. The company has invested capital and leveraged existing knowledge to go after new markets. Security Identity Management and Linux are two fast-growing markets in which Novell has been building a name for itself. Columbia Wanger Asset Management's technology analyst Ben Andrews purchased Novell under the assumption that at least one of these markets would drive Novell's revenue and earnings over the next one to two years. Wall Street has become aware of Novell's push into Linux and has doubled the price of its shares. Novell's bottom line pay out has yet to come, but we believe it is on the right track. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE, MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE. * LIBERTY ACORN USA WAS RENAMED COLUMBIA ACORN USA ON OCTOBER 13, 2003.

THE VALUE OF A $10,000 INVESTMENT IN COLUMBIA ACORN USA >September 4, 1996 through December 31, 2003 Illustration is based on a hypothetical $10,000 investment in Class A shares of the Fund, which includes the 5.75% maximum initial sales charge. The Fund commenced operations on 9/4/1996, but until 10/16/2000, offered only the shares that are now designated Class Z shares. The historical performance of Class A, B and C shares (newer class shares) for the period prior to 10/16/2000 is based on the performance of Class Z shares. The Class A, B and C share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between the Class A, B, and C and Class Z. Had the expense differential been reflected, the returns for periods prior to the inception of the newer class shares would have been lower. Performance may reflect any voluntary waiver or reimbursement of Fund expenses by the Advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. The Russell 2000 is a market-weighted index of 2,000 smaller U.S. companies formed by taking the largest 3,000 U.S. companies and eliminating the largest 1,000.

Olson After three years of posting dreary results, the international markets rose sharply in 2003. Columbia Acorn International Select finished the year up 41.11% (Class A shares, without sales charge) vs. a 49.65% gain for the benchmark Citigroup World ex-US Cap Range $2-10B Index and a 38.59% return for the large-cap MSCI EAFE Index. In the fourth quarter, the Fund gained 16.91%, outperforming the benchmark return of 15.81% and nearing the MSCI EAFE gain of 17.08%. Market interest in Japan and in more speculative stocks in general cooled in the fourth quarter, benefiting the Fund's relative return. But the Fund's more conservative stance toward Japan and higher-risk stocks dampened annual performance. Still, an annual return of nearly 42%, achieved without speculative maneuvering, should delight most shareholders. For the quarter, three of the four biggest winners in the Fund were banks offering niche services. Anglo Irish Bank, the Fund's largest holding, finished up 48% in the quarter. The corporate lending environment in the United Kingdom remains robust and Anglo Irish Bank continued to benefit. For the year, shares were up over 125%. Another winner in Columbia Acorn International Select was Den Norske Bank, a full-service commercial bank in Norway. Shares finished up 39% in the quarter and up 52% for the year. Ireland's Depfa Bank, a provider of public-sector financing, finished the quarter up 31%. For the year, shares were up 156%. The Fund's worst stocks for the quarter included Parmalat, the big dairy producer in Italy. Shares fell 55% when it was revealed that a huge cash reserve on its books was falsified. We limited the Fund's downside risk early on by halving its position in the stock when concerns first surfaced, selling those shares for a slight gain. We sold out of the Fund's remaining position shortly before the company went bankrupt. Another stock dragging down performance this quarter was Terumo, a maker of pharmaceuticals and medical supplies in Japan. Continued cuts in drug reimbursements and a steady decline in the number of new drugs coming to market slowed growth in pharmaceutical sales. The share price fell 3% during the quarter and we sold the Fund's position in the stock. /s/ Todd M. Narter /s/ Christopher J. Olson Todd M. Narter Christopher J. Olson CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER More Than The Name - ------------------------- You Know The Swatch brand name conjures up an image of a colorful, plastic watch that was a must-have for trendy teens in the '80s. While the Swatch watch continues to attract buyers, the earnings growth for this Swiss watchmaker is coming from its higher-end brands Omega and Brequet. Demand for the pricier lines is increasing in China and in the rest of the Asia Pacific region. We added the stock to Columbia Acorn International Select because we believe Swatch has a solid brand and is a low cost producer. Valuations are also good. After appreciating 27% in the quarter, the shares still sell at a discount to its peers. MID-CAP STOCKS TEND TO BE MORE VOLATILE AND MAY BE LESS LIQUID THAN THE STOCKS OF LARGER COMPANIES.

THE VALUE OF A $10,000 INVESTMENT IN COLUMBIA ACORN INTERNATIONAL SELECT >November 23, 1998 through December 31, 2003 Illustration is based on a hypothetical $10,000 investment in Class A shares of the Fund, which includes the 5.75% maximum initial sales charge. The Fund commenced operations on 11/23/1998, but until 10/16/2000, offered only the shares that are now designated Class Z shares. The historical performance of Class A, B and C shares (newer class shares) for the period prior to 10/16/2000 is based on the performance of Class Z shares. The Class A, B and C share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between Class A, B and C and Class Z. Had the expense differential been reflected, the returns for periods prior to the inception of the newer class shares would have been lower. Performance may reflect any voluntary waiver or reimbursement of Fund expenses by the Advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower.

Park Columbia Acorn Select returned 4.81% (Class A shares, without sales charge) during the fourth quarter, behind the benchmark S&P MidCap 400's 13.19% return and the S&P 500's 12.18% gain. For 2003, the Fund was up 29.95%, trailing the S&P MidCap 400's 35.62% return but beating the S&P 500's 28.69% gain. While we are pleased with the Fund's absolute result, we are disappointed that Columbia Acorn Select underperformed since it was leading its primary benchmark through the first three quarters of the year. Electronic Arts gained 97% in 2003, as sales and earnings consistently beat expectations. Guidant, the Fund's largest position, returned 92% as investors came to appreciate the company's fast growing defibrillator business as well as its potential growth making drug-eluting stents. (A stent is a little wire-mesh tube that keeps an artery open after an angioplasty procedure.) On the downside, First Health Group, one of the Fund's biggest positions, fell 20% for the year as the company lowered its sales and earnings for 2004 due to increased competition in the managed-care industry. While obviously disappointed, we believe the long-term outlook remains sound and we have added to the Fund's position. Most other losses for the year were relatively small in position size or percentages. In fact, all losses combined contributed to just a 3.16% drop for the Fund in 2003. Perhaps our biggest detractor was the conservative nature of Columbia Acorn Select; only five of the Fund's stocks were up 70% or more. While the market has rewarded the Fund's more conservative stance in the past, highly speculative stocks had the most impressive gains in 2003 and Columbia Acorn Select did not keep pace. Furthermore, as the market has bounced back, we have seen few opportunities to buy such stocks at prices that fairly compensate us for the risks incurred. I am justifiably proud of the terrific efforts put forth by our investment team in 2003. My thanks to Ralph Wanger, Chuck McQuaid, Rob Mohn, Ben Andrews, Susie Hultquist, Harold Lichtenstein, Grant McKay, Rob Chalupnik, Todd Griesbach, David Frank, and John Emerson for their invaluable contributions. I am also grateful to Shelley Maish and Mike Olah for providing Herculean efforts in trading throughout the year. Finally, thank you for your continued support as a Columbia Acorn Select shareholder. /s/ John H. Park John H. Park LEAD PORTFOLIO MANAGER Weight Watchers -- - ---------------------------------------- A Winning Loser The first question you ask a successful dieter is, "How did you lose the weight?" This marketing has contributed to Weight Watchers' unique business model by which its customers actually perpetuate the success of the business. With over 40 years in the business, the Weight Watchers' brand has become synonymous with healthy weight loss. Demand is more robust than ever with obesity rates at an all time high both domestically and in international markets. The company generates significant free cash flow due to fat profit margins and slim capital expenditure requirements, which it has been using to acquire franchises, pay down debt and repurchase stock -- all accretive to earnings. The stock has been under pressure recently as attendance growth has moderated due to the current popularity of the Atkins/high protein diet. History has shown us though that diet fads come and go, similar to excess weight, and we believe the sensibility of the Weight Watchers' program is one that dieters will return to, as will investors to the stock.

THE VALUE OF A $10,000 INVESTMENT IN COLUMBIA ACORN SELECT >November 23, 1998 through December 31, 2003 Illustration is based on a hypothetical $10,000 investment in Class A shares of the Fund, which includes the 5.75% maximum initial sales charge. The Fund commenced operations on 11/23/1998, but until 10/16/2000, offered only the shares that are now designated Class Z shares. The historical performance of Class A, B and C shares (newer class shares) for the period prior to 10/16/2000 is based on the performance of Class Z shares. The Class A, B and C share returns are not restated to reflect any expense differential (e.g., Rule 12b-1 fees) between Class A, B and C and Class Z. Had the expense differential been reflected, the returns for periods prior to the inception of the newer class shares would have been lower. Performance may reflect any voluntary waiver or reimbursement of Fund expenses by the Advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results would have been lower. The S&P MidCap 400 is a broad, market-weighted index of 400 stocks that are in the next size/tier down from the S&P 500. The index is unmanaged and returns for the index and the Fund include reinvested dividends and capital gains. It is not possible to invest directly in an index.

McQuaid Photo of Harvey Hirchhorn The Columbia Thermostat Fund completed its first full year of operations in 2003. The Fund rebalances between five stock funds and three bond funds according to a simple mechanical rule, quite like the way your home thermostat keeps the room temperature steady. The logical construction of the Fund appealed to many people, so assets at year-end were nearly $128 million, what we believe to be a very good number for a start-up fund. Investment performance for the Fund was satisfactory, up 7.20% (Class A shares, without sales charge) in the fourth quarter and 19.43% for the year Equities FOURTH QUARTER 1-YEAR WEIGHTING TOTAL RETURN TOTAL RETURN FUND IN SECTOR 2003 2003 - --------------------------------------------------------- Columbia 20% 14.45% 45.68% Acorn Fund - --------------------------------------------------------- Columbia 15% 4.97% 30.61% Acorn Select - --------------------------------------------------------- Columbia Growth 25% 9.42% 26.47% Stock Fund - --------------------------------------------------------- Columbia Growth 25% 11.77% 19.51% & Income Fund - --------------------------------------------------------- Columbia Mid Cap 15% 13.90% 27.82% Value Fund - --------------------------------------------------------- WEIGHTED AVERAGE 100% 11.02% 29.40% - --------------------------------------------------------- Fixed Income FOURTH 1-YEAR QUARTER WEIGHTI TOTAL RETURN TOTAL RETURN FUND IN SECTOR 2003 2003 - --------------------------------------------------------- Columbia Federal 30% 0.11% 2.26% Securities Fund - --------------------------------------------------------- Columbia 50% 1.46% 9.50% Intermediate Bond Fund - --------------------------------------------------------- Columbia High Yield Fund 20% 2.89% 11.49% - --------------------------------------------------------- WEIGHTED AVERAGE 100% 1.34% 7.73% - --------------------------------------------------------- Columbia Thermostat Fund Rebalancing in 2003 - --------------------------------------------------------- Stock/Fixed Income allocation 01/01/03: 70% stock, 30% fixed income Stock/Fixed Income allocation 12/31/03: 50% stock, 50% fixed income FOURTH QUARTER 1-YEAR 2003 2003 - ------------------------------------------------- Times stocks increased 0 3 - ------------------------------------------------- Times stocks decreased 3 9 - ------------------------------------------------- TOTAL 3 12 (see Page 3 for index comparisons). By construction, the Fund should be expected to have a return somewhere between the stock market and the bond market, and it did. The Fund's equity portfolio had a 29.40% return for the year, and the fixed income piece was up 7.73%. Thermostat's equity funds were 50% in small-cap, mid-cap and value funds, which was an overweighting in these categories vs. the entire market; this was a good idea in 2003, as these funds outperformed the large-company index as measured by the S&P 500 Index. The Fund's rebalancing system added some moderate value, but as the year unfolded, a high equity weighting throughout the year would have worked out better. The Thermostat system is likely to produce its best results in a market with lots of up-and-down moves. In 2003, the last 10 months of the year featured a steady uptrend for stocks, so shareholders would have done better by having all their money in an equity fund such as Columbia Acorn Fund. Of course, one cannot know that at the beginning of the year, which is why Columbia Thermostat makes sense for conservative investors. /s/ Ralph Wanger /s/ Charles P. McQuaid Ralph Wanger Charles P. McQuaid CO-PORTFOLIO MANAGER CO-PORTFOLIO MANAGER /s/ Harvey Hirchhorn Harvey Hirchhorn CO-PORTFOLIO MANAGER THE VALUE OF AN INVESTMENT IN THE FUND IS BASED PRIMARILY ON THE PERFORMANCE OF THE UNDERLYING PORTFOLIO FUNDS AND THE ALLOCATION OF THE FUND'S ASSETS AMONG THEM. AN INVESTMENT IN THE UNDERLYING FUNDS MAY PRESENT CERTAIN RISKS, INCLUDING STOCK MARKET FLUCTUATIONS THAT OCCUR IN RESPONSE TO ECONOMIC AND BUSINESS DEVELOPMENTS; AND A GREATER DEGREE OF SOCIAL, POLITICAL AND ECONOMIC VOLATILITY ASSOCIATED WITH INTERNATIONAL INVESTING. INVESTING IN SMALL-AND MID-CAP STOCKS MAY PRESENT SPECIAL RISKS INCLUDING POSSIBLE ILLIQUIDITY AND GREATER PRICE VOLATILITY THAN STOCKS OF LARGER, MORE ESTABLISHED COMPANIES. CHANGES IN INTEREST RATES AND CHANGES IN THE FINANCIAL STRENGTH OF ISSUERS OF LOWER-RATED BONDS MAY ALSO AFFECT UNDERLYING FUND PERFORMANCE. THE FUND IS ALSO SUBJECT TO THE RISK THAT THE INVESTMENT ADVISER'S DECISIONS REGARDING ASSET CLASSES AND PORTFOLIO FUNDS WILL NOT ANTICIPATE MARKET TRENDS SUCCESSFULLY, RESULTING IN A FAILURE TO PRESERVE CAPITAL OR LOWER TOTAL RETURN. IN ADDITION, THE FUND MAY BUY AND SELL SHARES OF THE PORTFOLIO FUNDS FREQUENTLY. THIS MAY RESULT IN HIGHER TRANSACTION COSTS AND ADDITIONAL TAX LIABILITY.

See accompanying notes to financial statements 63 Columbia Acorn Family of Funds >Notes to Financial Statements 1. Nature of Operations Columbia Acorn Fund, Columbia Acorn International, Columbia Acorn USA, Columbia Acorn International Select and Columbia Acorn Select (the "Funds") are series of Columbia Acorn Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of each Fund is to seek long-term growth of capital. The Funds may issue an unlimited number of shares. The Funds offer four classes of shares: Class A, Class B, Class C and Class Z. Class A shares are sold with a front-end sales charge. A contingent deferred sales charge ("CDSC") is assessed to Class A shares purchased without an initial sales charge on redemptions made within eighteen months on an original purchase of $1 million to $25 million. Class B shares are subject to a contingent deferred sales charge. Class B shares will convert to Class A shares in three, four or eight years after purchase, depending on the program under which shares are purchased. Class C shares are subject to a contingent deferred sales charge on redemptions made 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. Generally, you may exchange your Class Z or Class A shares of the Fund for shares of another fund at no additional charge. However, if you exchange Class Z shares of Columbia Acorn International or Columbia Acorn International Select that you have owned 60 days or less for Class Z shares of a fund distributed by Columbia Funds Distributor, Inc., that does not have a redemption fee (including Columbia Acorn Fund, Columbia Acorn USA and Columbia Acorn Select), the Fund will charge you a redemption fee of 2% of the redemption proceeds. Exchanges between Columbia Acorn International and Columbia Acorn International Select (or a fund distributed by Columbia Funds Distributor, Inc. that has a redemption fee) will not be subject to the 2% redemption fee. In addition, if you redeem shares of Columbia Acorn International or Columbia Acorn International Select that you have owned 60 days or less, the Fund will charge you a redemption fee of 2% of redemption proceeds, with certain exceptions. See "Fund Policy on Trading of Fund Shares and Redemption Fees" as disclosed within the Funds' prospectus for more information. The financial highlights for Class Z shares are presented in a separate annual report. The annual financial statements for the Columbia Thermostat Fund, another Fund of the Trust, begin on page 71 of this report. Effective October 13, 2003, the Funds changed their name from Liberty Acorn Fund to Columbia Acorn Fund, Liberty Acorn International to Columbia Acorn International, Liberty Acorn USA to Columbia Acorn USA, Liberty Acorn Foreign Forty to Columbia Acorn International Select and Liberty Acorn Twenty to Columbia Acorn Select. Also on that date, the Trust changed its name from Liberty Acorn Trust to Columbia Acorn Trust. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are borne pro rata on the basis of the relative net assets of all classes, except each class bears certain expenses unique to that class such as distribution services, transfer agent, and certain other class specific expenses. Differences in class expenses may result in payment of different dividend distributions for each class. All the share classes of the Trust have equal rights with respect to voting subject to class specific arrangements. On July 26, 2002, Columbia Acorn USA acquired all of the net assets of the Stein Roe Small Company Growth Fund ("Stein Roe Fund") pursuant to a plan of reorganization approved by the Stein Roe Fund shareholders on June 28, 2002. The acquisition was accomplished by a tax-free exchange of 1,139,488 shares of the Stein Roe Fund (valued at $10,096,640) for 726,123 shares of Columbia Acorn USA. The net assets of the Stein Roe Fund were combined with the net assets of Columbia Acorn USA on the acquisition date and included $3,125,202 of unrealized depreciation on investment. The aggregate net assets of Columbia Acorn USA immediately before and after acquisition were $306,945,066 and $317,041,706, respectively. 2. Significant Accounting Policies >Security valuation Investments are stated at fair value. Securities traded on securities exchanges or in over-the-counter markets in which transaction prices are reported are valued at the last sales price at the time of valuation. If a security is traded principally on the Nasdaq Stock Market Inc., the SEC-approved Nasdaq Official Closing Price will be applied. Securities for which there are no reported sales on the valuation date are valued at the latest bid quotation. Money market instruments having a maturity of 60 days or less from the valuation date are valued on an amortized cost basis, which approximates fair value. Securities for which quotations are not available are valued at a fair value as determined in good faith by the Board of Trustees. >Repurchase agreements The Funds may engage in repurchase agreement transactions. The Funds, through their custodians, receive delivery of underlying securities collateralizing repurchase agreements. The Funds' investment advisor determines 1-800-922-6769 64 that the value of the underlying securities is at all times at least equal to the resale price. In the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. >Foreign currency translations Values of investments denominated in foreign currencies are converted into U.S. dollars using the spot market rate of exchange at the time of valuation. Purchases and sales of investments and dividend and interest income are translated into U.S. dollars using the spot market rate of exchange prevailing on the respective dates of such transactions. The gain or loss resulting from changes in foreign exchange rates is included with net realized and unrealized gain or loss from investments, as appropriate. >Security transactions and investment income Security transactions are accounted for on the trade date (date the order to buy or sell is executed) and dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities are recorded as soon as the information is available to the Funds. Interest income is recorded on the accrual basis and includes amortization of discounts on money market instruments and long-term debt instruments when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. Awards from class action litigation may be recorded as a reduction of cost. 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. Results of operations for the year reflect a change in estimate of these components using more current tax reporting received from REIT investments. The change in estimate had no impact on each of the Fund's net assets. >Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. >Financial instruments Each Fund may purchase or sell exchange-traded financial futures contracts, which are contracts that obligate that Fund to make or take delivery of a financial instrument or the cash value of a securities index at a specified future date at a specified price. The Funds enter into such contracts to hedge a portion of their portfolio. Gains and losses are reflected as "Net Realized Gain (Loss) on Futures" in the Statements of Operations. Additionally, each Fund, except for Columbia Acorn USA and Columbia Acorn Select, may engage in portfolio hedging with respect to changes in foreign currency exchange rates by entering into forward foreign currency contracts to purchase or sell foreign currencies. The Statements of Operations reflect gains and losses as realized for closed forward foreign currency contracts and unrealized for open contracts. The Funds bear the market risk that arises from changes in the value of financial instruments and securities indices (futures contracts) or from changes in foreign currency rates (forward foreign currency contracts) and the credit risk should a counterparty fail to perform under such contracts. None of the Funds entered into any futures contracts or forward foreign currency contracts during the year ended December 31, 2003. >Fund share valuation Fund shares are sold and redeemed on a continuing basis at net asset value. Net asset value per share is determined daily as of the close of trading on the New York Stock Exchange on each day the Exchange is open for trading. All income, expenses (other than the Class A, Class B and Class C 12b-1 and distribution fees, and Class A, Class B, Class C and Class Z shares Transfer Agent fees) and realized and unrealized gains (losses) of a fund are allocated to each class proportionately on a daily basis for purposes of determining the net asset value of each class. Redemption fees are allocated to paid-in-capital of each class proportionately for the purposes of determining net asset value of each class. >Custody fees Custody fees are reduced based on each Fund's cash balances maintained with the custodian. The amount is disclosed as a reduction of total expenses in the Statement of Operations. >Federal income taxes The Funds have complied with the special provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distribute all their taxable income, as well as any net realized gain on sales of investments and foreign currency transactions reportable for federal income tax purposes. Accordingly, the Fund paid no federal income taxes and no federal income tax provision was required. >Distributions to Shareholders Distributions to shareholders are recorded on the ex-date. 65 Columbia Acorn Family of Funds >Notes to Financial Statements continued 3. Federal Tax Information Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences are primarily due to differing treatments for deferral of losses from wash sales, straddle deferrals, mark-to-market on futures contracts, current year distribution payable, foreign currency transactions, net operating losses, passive foreign investment companies, capital loss carryforwards, post-October losses and non-deductible expenses. Reclassifications are made to the Funds' capital accounts to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2003, permanent items identified and reclassified among the components of net assets are as follows: UNDISTRIBUTED NET INVESTMENT INCOME (ACCUMULATED NET ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN UNREALIZED LOSS) GAIN (LOSS) CAPITAL APPRECIATION --------------- ------------ -------- ------------ (IN THOUSANDS) Columbia Acorn Fund $13,265 $(13,067) $ (607) $ 409 Columbia Acorn International 1,034 (7,045) -- 6,011 Columbia Acorn USA 4,550 3,217 (7,767) -- Columbia Acorn International Select 20 (20) -- -- Columbia Acorn Select 4,409 (4,146) (263) -- Net investment income, net realized gains (losses) and net assets were not affected by this reclassification.

Transactions with Affiliates Effective October 13, 2003, the Fund's investment advisor changed its name from Liberty Wanger Asset Management, L.P. to Columbia Wanger Asset Management, L.P. ("Columbia WAM"). Columbia WAM, a wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a wholly-owned subsidiary of Fleet National Bank, which in turn is a wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"), furnishes continuing investment supervision to each Fund and is responsible for the overall management of the Funds' business affairs. Under the Funds' investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below for each fund. COLUMBIA ACORN FUND - -------------------------------------------------------------------------------- Net asset value: On the first $700 million .75% Next $1.3 billion .70% Net assets in excess of $2 billion .65% COLUMBIA ACORN INTERNATIONAL - -------------------------------------------------------------------------------- Net asset value: On the first $100 million 1.20% Next $400 million .95% Net assets in excess of $500 million .75% COLUMBIA ACORN USA - -------------------------------------------------------------------------------- Net asset value: On the first $200 million .95% Net assets in excess of $200 million .90% COLUMBIA ACORN INTERNATIONAL SELECT - -------------------------------------------------------------------------------- On average daily net assets: .95% COLUMBIA ACORN SELECT - -------------------------------------------------------------------------------- On average daily net assets: .90% >Expense Limit Columbia WAM has voluntarily agreed to reimburse the ordinary operating expenses (exclusive of distribution and service fees, interest, taxes and extraordinary expenses, if any) exceeding 1.45% of the average annual net assets for Columbia Acorn International Select Class A, B and C shares and 1.35% of the average annual net assets for Columbia Acorn Select Class A, B and C shares. Columbia WAM also provides administrative services to each Fund at an annual rate of .05% of average daily net assets. Effective October 13, 2003, Liberty Funds Distributor, Inc. changed its name to Columbia Funds Distributor, Inc. (the Distributor). The Distributor, an indirect subsidiary of Fleet, is each Fund's principal underwriter and receives no compensation on the sale of Class Z shares. For the year ended December 31 2003, Columbia Acorn Fund, Columbia Acorn International, Columbia Acorn USA, Columbia Acorn International Select and Columbia Acorn Select have been advised that the Distributor retained $1,525,281 in underwriting discounts on the sale of Class A shares and received contingent deferred sales charges of $1,676,890, $90,066, $131,820, $9,893, $154,202, respectively, on Class A, Class B and Class C share redemptions. Each Fund has adopted a 12b-1 plan which requires it to pay the Distributor a monthly service fee equal to 0.25% annually, of the average daily net assets attributable to Class A, Class B and Class C shares. The 12b-1 plan also requires each Fund to pay the Distributor a monthly distribution fee equal to 0.10%, 0.75% and 0.75% annually, of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. Effective October 13, 2003, Liberty Funds Services, Inc. changed its name to Columbia Funds Services, Inc. (the "Transfer Agent"). The Transfer Agent, an affiliate of the investment advisor, provides shareholder services to the 67 Columbia Acorn Family of Funds >Notes to Financial Statements continued Funds and receives reimbursement for out-of-pocket expenses. Transfer Agent fees are comprised of 0.07% annually, of the average daily net assets attributable to Class A, Class B and Class C shares plus charges based on the number of shareholder accounts and transactions. Certain officers and trustees of the Trust are also officers of Columbia WAM. The Trust makes no direct payments to its officers or trustees who are affiliated with Columbia WAM. Trustees' fees and expenses for the year ended December 31, 2003 are as follows: - ---------------------------------------------------------------- (IN THOUSANDS) Columbia Acorn Fund $ 369 Columbia Acorn International 70 Columbia Acorn USA 20 Columbia Acorn International Select 4 Columbia Acorn Select 14 - ---------------------------------------------------------------- The Trust provides a deferred compensation plan for its trustees. Under that plan, a trustee may elect to defer all or a portion of his or her compensation. Amounts deferred are retained by the Trust and represent an unfunded obligation of the Trust. The value of amounts deferred is determined by reference to the change in value of Class Z shares of one or more series of the Trust or a money market fund as specified by the trustee. Benefits under the deferred compensation plan are payable upon retirement. During the year ended December 31, 2003, the Funds engaged in purchase and sale transactions with funds that have a common investment adviser (or affiliated investment advisers), common Directors/Trustees, and/or common Officers. Those transactions complied with Rule 17a-7 under the Investment Company Act of 1940 and were as follows: FUNDS PURCHASES SALES - ---------------------------------------------------------------- (IN THOUSANDS) Columbia Acorn Fund $ 32,474 $ 5,329 Columbia Acorn International 7,022 33,552 Columbia Acorn USA 1,032 -- Columbia Acorn International Select -- 45 Columbia Acorn Select -- 1,204 - ---------------------------------------------------------------- 5.

Legal Proceedings The Securities and Exchange Commission (the "SEC"), the New York Attorney General and various other regulatory authorities are investigating late trading and market timing in mutual fund shares, and have sent information requests and subpoenas to certain affiliates of Columbia Management Group, Inc. ("CMG") (collectively, "Columbia"). These affiliates include the Distributor, Columbia Management Advisors, Inc. ("CMA"), and Columbia Wanger Asset Management, L.P. ("Columbia WAM"). CMA is the adviser to the Columbia Family of Funds, but is not the adviser to the Columbia Acorn Family of Funds. Columbia has not uncovered any instances where Columbia entities were knowingly involved in late trading of mutual fund shares. Columbia has identified a limited number of investors who had informal arrangements for trading shares of various funds managed by subsidiaries of CMG between 1998 and 2003. A majority of the transactions in connection with these arrangements occurred in one international fund and two domestic funds 1-800-922-6769 68 in the Columbia Family of Funds. A majority of the trading under these arrangements was made by three entities. A substantial majority of the trading had ended by October 2002. None of these arrangements exist today. Information relating to those trading arrangements has been supplied to various regulatory authorities. The SEC staff has issued notices to the effect that it has made a preliminary determination to recommend that the SEC bring civil enforcement actions, including injunctive proceedings, against the Distributor and CMA alleging that they have violated certain provisions of the federal securities laws. Columbia believes that those allegations are based principally on the trading arrangements referred to above. Columbia WAM has not been named in these notices. The Distributor and CMA are engaged in discussions with the SEC staff in an effort to reach a satisfactory resolution of these matters. However, there can be no assurance that such a resolution will be reached. Any potential resolution of these matters may include, but not be limited to, sanctions, financial penalties, damages or injunctions regarding the Distributor or CMA, and structural changes in the conduct of their business. Although Columbia does not believe that these regulatory developments or their resolution will have a material adverse effect on the Funds, or on the ability of the Distributor or Columbia WAM to provide services to the Funds, there can be no assurance that these matters or any publicity relating to these matters or other developments resulting from them will not adversely effect sales or redemptions of Fund shares or otherwise effect the Funds. Columbia Acorn Trust (the "Trust") and Columbia WAM are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in Columbia Acorn International Fund ("International Fund") for a period of more than 14 days during the five years prior to the filing of the lawsuit. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. The lawsuit alleges, in summary, that the Trust and Columbia WAM exposed International Fund shareholders to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of International Fund's securities had occurred after foreign markets had closed but before the calculation of the Fund's net asset value ("NAV"); (b) failing to implement International Fund's portfolio valuation and share pricing policies and procedures; (c) allowing portfolio valuation and share policies and procedures that benefited market timers at the expense of long-term shareholders; and (d) failing to know and implement applicable rules and regulations concerning the calculation of NAV. The Trust and Columbia WAM also are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in International Fund for a period of more than 14 days, without any stated limitation on the duration of the class period. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. This suit contains allegations and counts similar to those described above, and also includes an additional count under Section 36(a) of the Investment Company Act of 1940. The Trust, on behalf of International Fund, and Columbia WAM intend to defend both suits vigorously. The Trust does not believe that the pending actions will have a material adverse affect on the financial statements of any Fund, and Columbia WAM does not believe that the pending actions will have a material adverse affect on its ability to perform under its contracts with the Funds. 69 Columbia Acorn Family of Funds >Unaudited Information FEDERAL INCOME TAX INFORMATION: COLUMBIA ACORN FUND For the fiscal year ended December 31, 2003, the Fund designates long-term capital gains of $24,122.

Nature of Operations Columbia Thermostat Fund (the "Fund"), a series of Columbia Acorn Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust, commenced operations September 25, 2002. The Fund may issue an unlimited number of shares. The Fund currently offers four classes of shares: Class A, Class B, Class C and Class Z. On October 13, 2003, Class D was redesignated Class C. Class A shares are sold with a front-end sales charge. A contingent deferred sales charge may be assessed to Class A shares purchased without an initial sales charge on redemptions made within eighteen months on an original purchase of $1 million to $25 million. Class B shares are subject to a contingent deferred sales charge. Class B shares will convert to Class A shares in three, four or eight years after purchase, depending on the program under which shares are purchased. Class C shares are subject to a contingent deferred sales charge on redemptions made 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. The financial highlights for Class Z shares are presented in a separate annual report. The annual report for the other series of the Trust is also included in this report. The investment objective of the Fund is to provide long-term total return. The Fund pursues its investment objective by investing in shares of other mutual funds. As a `fund of funds', under normal circumstances, the Fund allocates at least 95% of its net assets among a selected group of stock and bond mutual funds (the "Portfolio Funds") according to the current level of the Standard & Poor's 500 Stock Index in relation to predetermined ranges set by the Fund's investment adviser. As of December 31, 2003, the Fund invested in five stock Portfolio Funds (Columbia Acorn Fund, Columbia Acorn Select Fund, Columbia Growth & Income Fund, Columbia Mid Cap Value Fund, Columbia Growth Stock Fund) and three bond Portfolio Funds (Columbia Federal Securities Fund, Columbia Intermediate Bond Fund and Columbia High Yield Fund). The Fund may also invest up to 5% of its net assets plus any cash received that day in cash, repurchase agreements, high quality short-term paper and government securities. 2. Significant Accounting Policies >Security valuation Investments in Portfolio Funds are valued at their net asset value as reported by the underlying funds. High quality short-term paper and government securities having a maturity of 60 days or less from the valuation date are valued on an amortized cost basis, which approximates fair value. >Repurchase agreements The Fund may engage in repurchase agreement transactions. The Fund, through its custodian, receives delivery of underlying securities collateralizing each repurchase agreement. The Fund's investment advisor determines that the value of the underlying securities is at all times at least equal to the resale price. In the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. >Security transactions and investment income Portfolio Fund transactions are accounted for on the trade date (date the order to buy or sell is executed). Dividend income and realized gain distributions from other funds are recorded on the ex-dividend date. Interest income is recorded on the accrual basis and includes amortization of discounts on money market instruments and short-term debt instruments when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. Awards from class action litigation may be recorded as a reduction of cost. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains. >Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. >Fund share valuation Fund shares are sold and redeemed on a continuing basis at net asset value. Net asset value per share is determined daily as of the close of trading on the New York Stock Exchange on each day the Exchange is open for trading. >Custody fees The custody fees are reduced based on the Fund's cash balance maintained with the custodian. The amount is disclosed as a reduction of total expenses in the Statement of Operations. 77 Columbia Thermostat Fund >Notes to Financial Statements, Continued >Federal income taxes The Fund has complied with the special provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distributes all of its taxable income, as well as any net realized gain on sales of Portfolio Fund shares and any distributions of net realized gains received by the Fund from its Portfolio Funds, reportable for federal income tax purposes. Accordingly, the Fund paid no federal income taxes and no federal income tax provision was required. >Distributions to Shareholders Distributions to shareholders are recorded on the ex-date. 3. Federal Tax Information Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences are primarily due to differing treatments of non-deductible expenses. Reclassifications are made to the Fund's capital accounts to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2003, permanent items identified and reclassified among the components of net assets are as follows: OVERDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN INCOME GAIN CAPITAL - -------------------------------------------------------------- (in thousands) $ 1 $ (1) $ -- Net investment income, net realized gains (losses) and net assets were not affected by this reclassification. The tax character of distributions paid during the year ended December 31, 2003 was as follows: LONG-TERM TAX ORDINARY CAPITAL RETURN OF INCOME GAINS CAPITAL - -------------------------------------------------------------- (in thousands) $ 771 $ 10 $ -- As of December 31, 2003, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM UNREALIZED INCOME CAPITAL GAINS APPRECIATION* - -------------------------------------------------------------- (in thousands) $ 197 $ 36 $ 9,253 * The difference between book-basis and tax-basis unrealized appreciation (depreciation), if applicable, is attributable primarily to the tax deferral of losses on wash sales. 4. Transactions with Affiliates Effective October 13, 2003, the Fund's investment advisor changed its name from Liberty Wanger Asset Management, L.P. to Columbia Wanger Asset Management, L.P. ("Columbia WAM"). Columbia WAM, a wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a wholly-owned subsidiary of Fleet National Bank, which in turn is a wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"), furnishes continuing investment supervision to each Fund and is responsible for the overall management of the Fund's business affairs. Under the Funds' investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 0.10% of the Fund's average daily net assets. >Expense Limit Columbia WAM has agreed to voluntarily reimburse the direct operating expenses (exclusive of distribution and service fees, interest, taxes, extraordinary expenses, if any, and expenses associated with the Fund's investment in other investment companies) exceeding 0.60% of the average annual net assets of the Fund's Class A, B and C shares. Effective August 1, 2003, Columbia WAM has agreed to contractually reimburse the direct operating expenses (exclusive of distribution and service fees, interest, taxes, extraordinary expenses, if any, and expenses associated with the Fund's investment in other investment companies) exceeding 0.25% of the average annual net assets of the Fund's Class A, B and C shares. Columbia WAM has also contracted to provide administrative services at an annual rate of .05% of the Fund's average daily net assets. Effective October 13, 2003 Liberty Funds Distributor, Inc., changed its name to Columbia Funds Distributor, Inc. (the Distributor). The Distributor, an indirect subsidiary of Fleet, is the Fund's principal underwriter and receives no compensation on the sale of Class Z shares. For the year ended December 31 2003, the Fund has been advised that the Distributor retained $178,252 in underwriting discounts on the sale of Class A and Class D shares prior to the share re-designation of Class D to Class C shares. The Fund has been advised that the Distributor received contingent deferred sales charges of $0, $26,208 and $557 on Class A, Class B and Class C share redemptions, respectively. 1-800-922-6769 78 The Fund has adopted a 12b-1 plan which requires it to pay the Distributor a monthly service fee equal to 0.25% annually, of the average daily net assets attributable to Class A, Class B and Class C shares. The 12b-1 plan also requires the Fund to pay the Distributor a monthly distribution fee equal to 0.25%, 0.75% and 0.75% annually, of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. Effective October 13, 2003, Liberty Funds Services, Inc., changed its name to Columbia Funds Services, Inc. (the "Transfer Agent"). The Transfer Agent, an affiliate of the investment advisor, provides shareholder services to the Fund and receives reimbursement for out-of-pocket expenses. Transfer Agent fees are comprised of 0.07% annually, of the average daily net assets attributable to Class A, Class B and Class C shares plus charges based on the number of shareholder accounts and transactions. Certain officers and trustees of the Trust are also officers of Columbia WAM. The Trust makes no direct payments to its officers and trustees who are affiliated with Columbia WAM. Trustees' fees and expenses for the year ended December 31, 2003, were $270. 5. Borrowing Arrangements The Trust participates in a $150 million credit facility, which was entered into to facilitate portfolio liquidity. No amounts have been borrowed under this facility for the year ended December 31, 2003. 6. Investment Transactions The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2003 were: - ------------------------------------------------------------ (in thousands) Purchases $ 144,197 Proceeds from sales $ 30,493 ============================================================ 7. Legal Proceedings The Securities and Exchange Commission (the "SEC"), the New York Attorney General and various other regulatory authorities are investigating late trading and market timing in mutual fund shares, and have sent information requests and subpoenas to certain affiliates of Columbia Management Group, Inc. ("CMG") (collectively, "Columbia"). These affiliates include the Distributor, Columbia Management Advisors, Inc. ("CMA"), and Columbia Wanger Asset Management, L.P. ("Columbia WAM"). CMA is the adviser to the Columbia Family of Funds, but is not the adviser to the Columbia Acorn Family of Funds. Columbia has not uncovered any instances where Columbia entities were knowingly involved in late trading of mutual fund shares. Columbia has identified a limited number of investors who had informal arrangements for trading shares of various funds managed by subsidiaries of CMG between 1998 and 2003. A majority of the transactions in connection with these arrangements occurred in one international fund and two domestic funds in the Columbia Family of Funds. A majority of the trading under these arrangements was made by three entities. A substantial majority of the trading had ended by October 2002. None of these arrangements exist today. Information relating to those trading arrangements has been supplied to various regulatory authorities. The SEC staff has issued notices to the effect that it has made a preliminary determination to recommend that the SEC bring civil enforcement actions, including injunctive proceedings, against the Distributor and CMA alleging that they have violated certain provisions of the federal securities laws. Columbia believes that those allegations are based principally on the trading arrangements referred to above. Columbia WAM has not been named in these notices. The Distributor and CMA are engaged in discussions with the SEC staff in an effort to reach a satisfactory resolution of these matters. However, there can be no assurance that such a resolution will be reached. Any potential resolution of these matters may include, but not be limited to, sanctions, financial penalties, damages or injunctions regarding the Distributor or CMA, and structural changes in the conduct of their business. Although Columbia does not believe that these regulatory developments or their resolution will have a material adverse effect on the Funds, or on the ability of the Distributor or Columbia WAM to provide services to the Funds, there can be no assurance that these matters or any publicity relating to these matters or other developments resulting from them will not adversely effect sales or redemptions of Fund shares or otherwise effect the Funds. Columbia Acorn Trust (the "Trust") and Columbia WAM are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in Columbia Acorn International Fund ("International Fund") for a period of more than 14 days during the five years prior to the filing of the lawsuit. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. The lawsuit alleges, in summary, that the Trust and Columbia WAM exposed 79 Columbia Thermostat Fund >Notes to Financial Statements, Continued International Fund shareholders to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of International Fund's securities had occurred after foreign markets had closed but before the calculation of the Fund's net asset value ("NAV"); (b) failing to implement International Fund's portfolio valuation and share pricing policies and procedures; (c) allowing portfolio valuation and share policies and procedures that benefited market timers at the expense of long-term shareholders; and (d) failing to know and implement applicable rules and regulations concerning the calculation of NAV. The Trust and Columbia WAM also are defendants in a lawsuit that seeks certification of a plaintiff class consisting of all persons in the United States who held shares in International Fund for a period of more than 14 days, without any stated limitation on the duration of the class period. The suit seeks compensatory and punitive damages, as well as interest, costs and attorney's fees. This suit contains allegations and counts similar to those described above, and also includes an additional count under Section 36(a) of the Investment Company Act of 1940. The Trust, on behalf of International Fund, and Columbia WAM intend to defend both suits vigorously. The Trust does not believe that the pending actions will have a material adverse affect on the financial statements of any Fund, and Columbia WAM does not believe that the pending actions will have a material adverse affect on its ability to perform under its contracts with the Funds. 1-800-922-6769 80 Columbia Thermostat Fund >Unaudited Information (in thousands) FEDERAL INCOME TAX INFORMATION: For the fiscal year ended December 31, 2003, the Fund designates long-term capital gains of $36. 30.23% of the ordinary income distributed by the Fund, in the year ended December 31, 2003, qualifies for the corporate dividends received deduction. For non-corporate shareholders 30.23%, of the maximum amount allowable under the Jobs and Growth Tax Reconciliation Act of 2003, of income earned by the Fund for the period January 1, 2003 to December 31, 2003 may represent qualified dividend income. Final information will be provided in your 2003 1099-DIV From. 81 REPORT OF INDEPENDENT AUDITORS TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF COLUMBIA ACORN TRUST We have audited the accompanying statements of assets and liabilities, including the statements of investments of Columbia Acorn Fund, Columbia Acorn International, Columbia Acorn USA, Columbia Acorn International Select, Columbia Acorn Select and Columbia Thermostat Fund, comprising the Columbia Acorn Trust, as of December 31, 2003, the related statements of operations, changes in net assets, and the financial highlights for the periods indicated therein.

A "control affiliate" is an entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the funds, and the term "adviser" is deemed to exclude any unaffiliated sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser. If such Fund Services or Fund-related Adviser Services are required during the period between the Audit Committee's regularly scheduled meetings, the Chairman of the Audit Committee has the authority to pre-approve the service, with reporting to the full Audit Committee at the next regularly scheduled meeting. The Audit Committee will waive pre-approval of Fund Services or Fund-related Adviser Services provided that the requirements under paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are met.

There were no such fees during the last two fiscal years. (h) The registrant's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.
