READ IT CAREFULLY BEFORE YOU INVEST OR SEND MONEY. THIS REPORT IS NOT AN OFFER OF THE SHARES OF THE COLUMBIA ACORN FUND FAMILY. THE DISCUSSION IN THE REPORT OF PORTFOLIO COMPANIES IS FOR ILLUSTRATION ONLY AND IS NOT A RECOMMENDATION OF INDIVIDUAL STOCKS. THE INFORMATION IS BELIEVED TO BE ACCURATE, BUT THE INFORMATION AND THE VIEWS OF THE PORTFOLIO MANAGERS MAY CHANGE AT ANY TIME WITHOUT NOTICE AND THE PORTFOLIO MANAGERS MAY ALTER A FUND'S PORTFOLIO HOLDINGS BASED ON THESE VIEWS AND THE FUND'S CIRCUMSTANCES AT THAT TIME. Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- UNDERSTANDING YOUR EXPENSES As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. ANALYZING YOUR FUND'S EXPENSES To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in the fund during the reporting period. The information in the following table is based on an initial investment of $1,000.00, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using actual operating expenses and total return for the fund. The amount listed in the "hypothetical" column assumes that the return each year is 5% before expenses and then applies each Fund's actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the reporting period. See the "Compare with other funds" information for details on using the hypothetical data. ESTIMATING YOUR ACTUAL EXPENSES To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period. 1. Divide your ending account balance by $1,000.00. For example, if an account balance was $8,600.00 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your fund. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. July 1, 2005 - December 31, 2005 Account value at the Account value at the Expenses paid during Fund's annualized beginning of the period ($) end of the period ($) the period ($) expense ratio (%)* - ------------------------------------------------------------------------------------------------------------------------------------ Actual Hypothetical Actual Hypothetical Actual Hypothetical - ------------------------------------------------------------------------------------------------------------------------------------ Wanger U.S. Smaller Companies 1,000.00 1,000.00 1,076.52 1,020.37 5.02 4.89 0.96 - ------------------------------------------------------------------------------------------------------------------------------------ Expenses paid during the period are equal to the fund's annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the investment adviser not waived a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund. As a shareholder of the fund, you do not incur any transaction costs, such as sales charges, redemption or exchange fees. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. The hypothetical example provided is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds whose shareholders may incur transaction costs. *For the six months ended 12/31/05. COMPARE WITH OTHER FUNDS Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transactional costs, such as sales charges or redemption or exchange fees, that may be incurred by shareholders of other funds. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. 1 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- [graphic: squirrel] NO ORDINARY PORTFOLIO MANAGERS I began working with Ralph Wanger, founder of Columbia Wanger Asset Management, in 1978. Shortly thereafter he issued the third quarter shareholder report for one of our retail funds. In it he wrote: "...hedonism is in... Let us explore the possibility that we have been going through the oldest cycle of all--from Good to Bad." In order to prove that badness was more profitable than goodness, Ralph tested two portfolios for 36-month price changes. The virtuous portfolio included Angelica, up 45%, and Church's Fried Chicken, up 520%. The wicked portfolio included Playboy, up 600%, and DeBeers Mines, up 59%.1 The wicked portfolio won. Ralph's footnote to his essay read: "This study was done by the usual techniques of Financial Analysis: (A) The stocks chosen had nothing to do with the subject, and (B) The portfolios were readjusted until the answer affirmed the hypothesis." At that point it became very clear to me that Ralph Wanger was no ordinary portfolio manager! Ralph parlayed his legendary shareholder reports into his book, A Zebra in Lion Country.2 The book could have been titled, The Wit and Wisdom of Ralph Wanger. In it Ralph admits that his first quarterly newsletters were serious and stuffy. He said that he gave market and economic forecasts that quickly became outdated. Then he decided, "If most mutual fund communications are both boring and wrong, well then, I figured, I'd rather be lively and wrong." There's a lot of Wisdom in A Zebra in Lion Country. Examples include: "Look for stocks that have basic value but are out of fashion." Ralph also wrote, "The greatest investment profit comes when an ugly duckling becomes a swan." And, "If a company's earnings beat the Merrill Lynch analyst's forecast by 2 cents, that doesn't excite me. I need a long-term reason to own a stock." And Ralph meant long term. "...you can't make five or ten or twenty times your money if you don't hold on to your stocks. Most people are delighted when a stock doubles, and quickly sell to lock in their gain," he wrote in his book. Ralph's long-term thinking was driven home in a report essay he wrote in June 1992: "What really makes for successful investing is having a few enormous hits. In 22 years, I've really had three Super Stocks." Houston Oil & Minerals was one. Houston Oil cost $220,000 in 1973 and went to $5.3 million in 1977. Another was Cray Research, which cost $1.5 million in 1978 and was worth $20 million in 1985. International Game Technology, a maker of slot machines, cost $5 million in 1988 and was worth $80 million by June 1992.3 Ralph also had his share of disasters. He wrote in that 1992 report, "There is one stock we tried to sell for two years and never got a bid on any of it. A stock like that just slides from 4 to 3 to 2 to 1 and finally disappears..." Ralph said, "It's kind of like a doctor saying don't worry about it, it's just going to shrivel up and fall off." Atchison Casting, an owner of steel foundries, was a painful example of this. Ralph began purchasing the stock in 1994 and it ended up being nearly worthless when it was sold in 2003. The wisdom here is that small-cap investing can be a winner's game. Let your winners run. On any individual stock, one can possibly make several thousand percent, but the most that one can lose is 100%. Small-cap investors will have some big percentage losers, but damage to portfolios can be minor as long as investors don't keep throwing money at them and if they maintain a well-diversified portfolio. How did Ralph use his genius and wisdom to build a successful firm? A few years after I joined Ralph we had a heated discussion about a stock. The next day I asked him if I had crossed the line during our debate. He looked at me kind of puzzled and said, course not, if we always agreed, why would I need you?" Ralph always respected differing opinions and created a culture of intellectual freedom. In an investment world full of wishful thinking, Ralph also demanded intellectual honesty. The ability to ask tough questions, get sound answers, discover good businesses, detect strong managers and then value stocks appropriately, requires intellectual honesty. Then it's time to act. I remember an analyst saying that a stock trades by appointment and Ralph responding, "Then make an appointment and buy it!" The culture that Ralph fostered allowed Columbia Wanger Asset Management to grow and helped its shareholders to prosper. Leah Zell's contribution to Columbia Wanger Asset Management has also been huge and complementary to Ralph's. Leah seemed to have the ability to see around corners strategically and make quick, good decisions. When Leah joined our team in 1984, she began as a domestic analyst following mostly real estate and retail stocks. Leah then became our first foreign analyst. She successfully launched our first international retail mutual fund, Acorn International, realizing great investment results, and taking the Fund from zero to one billion dollars in assets under management in 14 months. Of course, she could not have done it without a team. Leah built the international area at Columbia Wanger Asset Management. International investing requires all the skills needed for domestic investing, and more. At Columbia Wanger, we like to hire international analysts who also have language skills and cultural 2 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- knowledge. In a number of cases, Leah successfully mentored new analysts who had these traits and fine financial skills but had a lot to learn about security analysis. We at Columbia Wanger Asset Management are happy that Ralph and Leah kept their offices with us and have been advisors over the last two years. We've gotten good advice, but Ralph and Leah made it clear that the decisions were ours. In our semiannual report we published Ralph's last column, which appeared in this section. Ralph once said of writing his essays, "It is fun for me and only mildly irritating to our shareholders." We are grateful to have had Ralph's and Leah's presence and wisdom for all these years. On September 30, 2005, they retired from their advisory roles with the firm. DOMESTIC SMALL-CAP CYCLE Small caps have outperformed large caps for over six years now; by our reckoning, small caps bottomed vs. large caps in March 1999. The small-cap Russell 2500 Index returned 110% from that date through December 31, 2005, far outpacing the S&P 500, which returned 8%. In the past, small-cap stocks had long cycles of out- and under-performance vs. large caps. There is no science and there is no magic in predicting the exact top of a small-cap cycle. Perhaps small caps will continue to outperform--some believe small caps will outperform as long as rapid earnings growth continues and some others believe outperformance will persist until the overall market turns. Numerous economists are predicting higher inflation rates, and small caps did relatively well during the inflationary periods of the 1970s. However, when looking at price-to-earnings ratios, small caps appear expensive vs. large caps. Using another measure, price-to-book value, small caps appear somewhat more reasonably priced. While we don't think domestic small caps are back to their all-time relative high valuations, we do think small-cap domestic stocks on average are no longer cheap. We do not predict market cycles. We stick to what we believe we do best: buying reasonably priced small- and mid-cap stocks and when they enter periods of higher valuations, we try to become more selective. Over time this consistently applied approach has weathered the Funds through a variety of market cycles. While we certainly can't predict what the future holds, the best defense against unknown market factors is diversification across assets, which is a prudent and time-tested investment strategy. COLUMBIA WAM NEWS We are pleased to announce that Satoshi Matsunaga has joined our international analyst team covering Japan. He came on board in September. Before joining Columbia Wanger Asset Management, he was with Compass Advisers in New York. Satoshi holds an MBA from the University of Michigan and a bachelor's in economics from Keio University in Tokyo, Japan. As a Japanese national, Satoshi brings first-hand knowledge of the country and culture. After the close of the period, we hired a new energy analyst. In January, William Doyle came on board. Bill was most recently a manager of PPM America's credit analysis team where part of his responsibilities included following the high yield energy sector. Bill's degrees include an MBA from Loyola University in Chicago and bachelor's degrees in finance and history from Illinois State University. We are pleased to welcome Satoshi and Bill to the team. photo of: Charles P. Mcquaid /s/ Charles P. Mcquaid CHARLES P.

Wanger U.S. Smaller Companies gained 11.25% in 2005. This return more than doubled the 4.55% annual increase of the Russell 2000. The Fund's top returns came from the energy sector. Oil and gas producers Southwestern Energy, Ultra Petroleum, Quicksilver Resources and Western Gas Resources hit pay dirt thanks to increased demand and higher energy prices. Southwestern Energy gained 184%, Ultra Petroleum was up 133%, Quicksilver climbed 72% and Western Gas increased 62% for the year. After dropping in the third quarter on fears of slowed consumer spending, retail stocks came back strong in the fourth quarter, helping annual performance of the Fund's retail names. Chico's FAS gained 93%, Ann Taylor Stores increased 60% and teen retailer Abercrombie & Fitch was up 41% at year end. Our niche technology stocks benefited from strong earnings growth. Credit card processor Global Payments was up 60%. Plexus, a developer and manufacturer of electronic products, gained 75%. SSA Global Technologies, a developer of enterprise resource planning software, ended the year up 65%. On the downside, Seachange International, a developer of systems used for video-on-demand, was off 55% in the year as cable and telephone customers delayed new video-on-demand launches. Spanish Broadcasting Systems lost 52% as revenues failed to meet expectations. Petco Animal Supplies fell 44% in the year due to weaker than expected sales and elevated distribution costs. As always, we will continue to search for what we believe to be the best small-cap stocks to add to the portfolio. 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. As of 12/31/05, the Fund's positions in the stocks mentioned were: Southwestern Energy, 0.5%; Ultra Petroleum, 1.5%; Quicksilver Resources, 0.5%; Western Gas, 0.9%; Chico's FAS, 0.7%; Ann Taylor Stores, 0.6%; Abercrombie & Fitch, 1.9%; Global Payments, 1.7%; Plexus, 0.3%; SSA Global Technologies, 0.4%; Seachange International, 0.2%; Spanish Broadcasting Systems, 0.2%; Petco Animal Supplies, 0.8%. 4 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- GROWTH OF A $10,000 INVESTMENT IN WANGER U.S. SMALLER COMPANIES TOTAL RETURN FOR EACH PERIOD, MAY 3, 1995 (INCEPTION DATE) THROUGH DECEMBER 31, 2005 AVERAGE ANNUAL TOTAL RETURN ------------------------------------------------ 1 year 5 years 10 years Life of fund 11.25% 11.81% 15.26% 15.84% WANGER U.S. SMALLER COMPANIES: $47,992 Russell 2000: $29,152 WANGER U.S. SMALLER COMPANIES Russell 2000 5/3/95 10000 10000 5/31/95 9870 10179 6/30/95 10770 10707 10000 10000 11940 11559 9/30/95 12060 11765 11380 11239 11640 11711 12/31/95 11600 12020 11950 12007 12580 12381 3/31/96 13297 12633 14690 13309 15471 13833 6/30/96 15351 13265 14529 12107 15090 12810 9/30/96 15792 13310 15902 13105 16423 13645 12/31/96 17004 14003 17475 14282 16994 13936 3/31/97 16366 13279 16355 13316 17986 14797 6/30/97 19093 15431 20201 16149 20703 16519 9/30/97 22395 17728 21995 16949 21892 16839 12/31/97 22005 17134 21554 16864 23379 18111 3/31/98 24865 18858 25803 18962 24887 17941 6/30/98 25361 17978 23959 16523 20358 13315 9/30/98 20875 14356 21598 14942 22601 15725 12/31/98 23916 16698 23453 16920 22223 15549 3/31/99 22388 15792 24321 17207 25005 17459 6/30/99 26375 18248 27216 17747 25677 17090 9/30/99 25389 17094 26940 17163 28202 18188 12/31/99 29909 20247 28911 19922 30029 23212 3/31/00 29077 21682 26164 20377 24858 19189 6/30/00 25545 20862 25174 20191 26672 21731 9/30/00 26741 21093 26768 20151 25147 18083 12/31/00 27469 19636 27936 20658 27469 19302 3/31/01 26306 18358 29276 19794 30473 20281 6/30/01 31669 20981 31710 19845 30308 19204 9/30/01 26567 16619 27214 17592 28988 18954 12/31/01 30597 20124 30528 19914 29634 19369 3/31/02 32219 20925 32247 21116 30652 20179 6/30/02 28754 19178 25027 16281 24959 16240 9/30/02 23226 15073 24546 15557 26499 16945 12/31/02 25454 16002 24959 15559 24601 15089 3/31/03 24670 15283 26815 16732 29125 18528 6/30/03 29717 18863 31463 20043 33168 20962 9/30/03 32549 20575 35643 22303 36193 23094 12/31/03 36455 23563 38105 24587 37789 24807 3/31/04 37417 25038 36592 23762 37857 24140 6/30/04 38765 25157 36578 23463 36358 23342 9/30/04 37665 24438 38999 24919 41763 27080 12/31/04 43138 27882 42368 26719 43124 27171 3/31/05 42794 26393 40786 24882 42973 26510 6/30/05 44582 27533 46699 29277 46204 28734 9/30/05 46727 28825 45517 27930 47882 29286 12/31/05 47992 29152 This graph compares the results of $10,000 invested in Wanger U.S. Smaller Companies on May 3, 1995 (the date the Fund began operations) through December 31, 2005, with the Russell 2000.

See accompanying notes to financial statements. 15 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 1. NATURE OF OPERATIONS Wanger U.S. Smaller Companies (the "Fund"), is a series of Wanger Advisors Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of the Fund is to seek long-term growth of capital. The Fund is available only for allocation to certain life insurance company separate accounts established for the purpose of funding qualified and non-qualified variable annuity contracts, and variable life insurance policies and may also be offered directly to certain types of pension plans and retirement arrangements. 2. SIGNIFICANT ACCOUNTING POLICIES SECURITY VALUATION Securities of the Fund are valued at market value or, if a market quotation for a security is not readily available or is deemed not to be reliable because of events or circumstances that have occurred between the market quotation and the time as of which the security is to be valued, the security is valued at a fair value determined in accordance with procedures established by the Board of Trustees. 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 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. Short-term debt obligations 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 readily available and any other assets are valued as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. The Trust has retained an independent statistical fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security. REPURCHASE AGREEMENTS The Fund may engage in repurchase agreement transactions. The Fund, through its custodians, 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 repurchase price including interest. 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 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 Fund. Interest income is recorded on an accrual basis and includes amortization of discounts on short-term debt obligations and on long-term debt obligations when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. The Fund estimates 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 has no impact on the Fund's net assets. RESTRICTED SECURITIES Restricted securities are securities that may only be resold upon registration under federal securities laws or in transactions exempt from registration. In some cases, the issuer of restricted securities has agreed to register such securities for resale at the issuer's expense either upon demand by the Fund or in connection with another registered offering of the securities. Many restricted securities may be resold in the secondary market in transactions exempt from registration. Such restricted securities may be determined to be liquid under criteria established by the Board of Trustees. The Fund will not incur any registration costs upon such resale. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. 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 ("the Exchange") on each day the Exchange is open for trading by dividing the total value of the Fund's investments and other assets, less liabilities, by the number of Fund shares outstanding. CUSTODY FEES/CREDITS Custody fees are reduced based on the Fund's cash balances maintained with the custodian. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. The amount is disclosed as a reduction of total expenses in the Statement of Operations. INDEMNIFICATION In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Trust's organizational documents, the Trustees and Officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these warranties and indemnities to be minimal. FEDERAL INCOME TAXES The Fund has complied with the provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distributes all its 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 The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund's capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. 16 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS For the year ended December 31, 2005, permanent book and tax basis differences resulting primarily from differing treatments for REIT adjustments were identified and reclassified among the components of the Fund's net assets as follows: UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED INCOME GAIN PAID-IN CAPITAL -------------- ------------- --------------- $(92,302) $92,302 -- Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. As of December 31, 2005, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM NET UNREALIZED INCOME CAPITAL GAINS APPRECIATION* -------------- ------------- --------------- $3,544,817 $50,572,798 $490,451,932 * The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales and REITadjustments. Capital loss carryforwards of $5,327,851 were utilized during the year ended December 31, 2005. 4. TRANSACTIONS WITH AFFILIATES Columbia Wanger Asset Management, L.P., ("Columbia WAM") a wholly-owned subsidiary of Columbia Management Group, Inc., (CM) which in turn is an indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), furnishes continuing investment supervision to the Fund and is responsible for the overall management of the Fund's business affairs. Effective March 8, 2005, under the Fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below: AVERAGE DAILY NET ASSETS ANNUAL FEE RATE For the first $100 million 0.99% Next $150 million 0.94% In excess of $250 million 0.89% Prior to March 8, 2005, under the Fund's investment management agreement, fees were accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below: AVERAGE DAILY NET ASSETS ANNUAL FEE RATE For the first $100 million 1.00% Next $150 million 0.95% In excess of $250 million 0.90% In accordance with the terms of the Assurance of Discontinuance with the New York Attorney General, Columbia WAM waived a portion of the fees payable under the Fund's investment management agreement so that those fees were retained at the following annual rates as a percentage of average daily net assets: 0.99% - up to 100 million; 0.94% - $100 million to $250 million; 0.89% - $250 million and over. The fee waiver was effective from January 1, 2005 through March 8, 2005, but applied as if it had gone into effect on December 1, 2004. Fees waived by Columbia WAM amounted to $21,040 for the year ended December 31, 2005. The investment advisory agreement also provides that through April 30, 2005 Columbia WAM will reimburse the Fund to the extent that ordinary operating expenses, (computed based on the net custodian fees) exceed an annual percentage of 2.00% of average daily net assets. There was no reimbursement for the year ended December 31, 2005. For the year ended December 31, 2005, the Fund's annualized effective investment advisory fee rate was 0.90%. 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. For the year ended December 31, 2005, the Fund paid $135,904 to trustees not affiliated with Columbia WAM. The Board of Trustees appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. These expenses are disclosed separately as "Compliance fees" on the Statement of Operations. Columbia Management Distributors, Inc. (formerly Columbia Funds Distributor, Inc.), a wholly owned subsidiary of BOA, serves as the principal underwriter of the Trust and receives no compensation for its services. Columbia Management Services, Inc. (formerly Columbia Funds Services, Inc.) (the "Transfer Agent"), a wholly owned subsidiary of BOA, provides shareholder services to the Fund and has subcontracted with Boston Financial Data Services ("BFDS") to serve as subtransfer agent. For such services, the Transfer Agent receives a fee, paid monthly, at the annual rate of $21.00 per open account. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. An affiliate may include any company in which a fund owns five percent or more of its outstanding voting shares. On December 31, 2005, the Fund held five percent or more of the outstanding voting securities of one or more companies. Details of investments in those affiliated companies are presented on page 12. During the year ended December 31, 2005, the Fund engaged in purchase and sales transactions with funds that have a common investment advisor (or affiliated investment advisors), common Directors/Trustees, and/or common Officers. These purchase and sale transactions complied with the provisions of Rule 17a-7 under the Investment Company Act of 1940 and were $0 and $372,750, respectively. 5. BORROWING ARRANGEMENTS The Trust participates in a $150,000,000 credit facility, which was entered into to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. No amounts were borrowed under this facility for the year ended December 31, 2005. 6. FUND SHARE TRANSACTIONS Proceeds and payments on Fund shares as shown in the statement of changes in net assets are in respect of the following numbers of shares: Year ended Year ended December 31, 2005 December 31, 2004 - -------------------------------------------------------------------------- Shares sold 8,661,418 8,353,055 - -------------------------------------------------------------------------- Less shares redeemed 2,637,907 2,612,387 - -------------------------------------------------------------------------- Net increase in shares outstanding 6,023,511 5,740,668 - -------------------------------------------------------------------------- 17 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 7. INVESTMENT TRANSACTIONS The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2005 were $363,861,171 and $125,617,863. 8. LEGAL PROCEEDINGS Columbia WAM, Columbia Acorn Trust, another mutual fund family advised by Columbia WAM, and the trustees of Colombia Acorn Trust, are named as defendants in class and derivative complaints which have been consolidated in a Multi-District Action in the federal district court for the District of Maryland. These lawsuits contend that defendants permitted certain investors to market time their trades in certain Columbia Acorn Funds. The Multi-District Action is ongoing. However, all claims against Columbia Acorn Trust and the independent trustees of Columbia Acorn Trust have been dismissed. Columbia WAM, the Columbia Acorn Funds and the trustees of Columbia Acorn Trust are defendants in a consolidated lawsuit filed in the federal district court of Massachusetts alleging that Columbia WAM used Fund assets to make undisclosed payments to brokers as an incentive for the brokers to market the Columbia Acorn Funds over the other mutual funds to investors. The complaint alleges Columbia WAM and the Trustees of the Trust breached certain common laws duties and federal laws. All claims against all defendants in this lawsuit have been dismissed. However, the plaintiffs have filed a notice of appeal with the First Circuit Court of Appeals. The Columbia Acorn Trust and Columbia WAM are also defendants in a class action lawsuit that alleges, in summary, that the Columbia Acorn Trust and Columbia WAM exposed shareholders of Columbia Acorn International to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of that Fund's securities had occurred after foreign markets had closed but before the calculation of the Funds' net asset value (NAV"); (b) failing to implement the Fund's portfolio valuation and share pricing policies and procedures; and (c) failing to know and implement applicable rules and regulations concerning the calculation of NAV (the "Fair Valuation Lawsuit"). The Seventh Circuit ruled that the plaintiffs' state law claims were preempted under federal law resulting in the dismissal of plaintiffs' complaint. However, plaintiffs are in the process of appealing that decision before the United States Supreme Court. On March 21, 2005, a class action complaint was filed against the Columbia Acorn Trust and Columbia WAM seeking to rescind the Contingent Deferred Sales Charges assessed upon redemption of Class B shares of Columbia Acorn Funds due to the alleged market timing of the Columbia Acorn Funds. In addition to the rescission of sales charges, plaintiffs seek recovery of actual damages, attorneys' fees and costs. The case has been transferred to the Multi-District Action in the federal district court of Maryland. The Columbia Acorn Trust and Columbia WAM intend to defend these suits vigorously. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Funds. In connection with the events described in detail above, various parties have filed suit against certain funds, their Boards and/or BOA (and affiliated entities). These suits are ongoing. However, based on currently available information, the Columbia Acorn Trust believes that the likelihood that these lawsuits will have a material adverse impact on any fund is remote, and Columbia WAM believes that the lawsuits are not likely to materially affect its ability to provide investment management services to the Fund. For the year ended December 31, 2005, CM has assumed $229,723 in consulting services and legal fees incurred by the Fund in connection with these matters. 18 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of Wanger U.S. Smaller Companies Fund: In our opinion, the accompanying statement of assets and liabilities, including the statement of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Wanger U.S. Smaller Companies Fund (a series of the Wanger Advisors Trust, hereinafter referred to as the "Fund") at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at December 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for the periods ended December 31, 2003 and prior were audited by other independent auditors whose report dated February 6, 2004 expressed an unqualified opinion on those financial statements.

("CMAI") and Columbia Funds Distributor, Inc., ("CFDI" and collectively with "CMAI," "CMG") in February 2005, allows CMAI to manage or advise a mutual fund, including the Wanger Advisors Trust's family of funds (the "WAT Funds" or "WAT" or "Trust"), only if the trustees of the WAT Funds appoint a "Senior Officer" to perform specified duties and responsibilities. One of these responsibilities includes "managing the process by which proposed management fees (including but not limited to, advisory fees) to be charged the WAT Fund[s] are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." The Order also provides that the Board of Trustees of the WAT Funds ("Board") must determine the reasonableness of proposed "management fees" by using either an annual competitive bidding process supervised by the Senior Officer or Independent Fee Consultant, or by obtaining "an annual independent written evaluation prepared by or under the direction of the Senior Officer or the Independent Fee Consultant." "Management fees" are only part of the costs and expenses paid by mutual fund shareholders. The expenses can vary depending upon the class of shares held but usually include: (1) investment management or advisory fees to compensate analysts and portfolio managers for stock research and portfolio management, as well as the cost of operating a trading desk; (2) administrative expenses incurred to prepare registration statements and tax returns, calculate the Funds' net asset values, maintain effective compliance procedures and perform recordkeeping services; (3) transfer agency costs for establishing accounts, accepting and disbursing funds, as well as overseeing trading in Fund shares; (4) custodial expenses incurred to hold the securities purchased by the Funds; and (5) distribution expenses, including commissions paid to brokers that sell the Fund shares to investors. Columbia Wanger Asset Management, L.P. ("CWAM"), the adviser to the WAT Funds, has proposed that the Trust enter into an agreement that "bundles" the first two categories listed above: advisory and administrative services. The fees paid under this agreement are referred to as "management fees." Other fund expenses are governed by separate agreements, in particular agreements with two CWAM affiliates: CFDI, the broker-dealer that underwrites and distributes the WAT Funds' shares, and Columbia Funds Services, Inc. ("CFSI"), the Funds' transfer agent. In conformity with the terms of the Order, this evaluation, therefore, addresses only the advisory and administrative contract between CWAM and the Trust, and does not extend to the other agreements. According to the Order, the Senior Officer's evaluation must consider at least the following: (1) Management fees (including components thereof) charged to institutional and other clients of CWAM for like services; (2) Management fees (including any components thereof) charged by other mutual fund companies for like services; (3) Costs to CWAM and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; (4) Profit margins of CWAM and its affiliates from supplying such services; (5) Possible economies of scale as the WAT Funds grow larger; and (6) The nature and quality of CWAM's services, including the performance of each WAT Fund. On November 17, 2004, the Board appointed me, Robert Scales, Senior Officer under the Order. The Board also determined not to pursue a competitive bidding process and instead, charged me with the responsibility of evaluating the WAT Funds' proposed advisory and administrative fee contract with CWAM in conformity with the requirements of the Order. This Report is an annual evaluation required under the Order. In discharging their responsibilities, the independent Trustees have also consulted independent, outside counsel. * * * This evaluation was performed in cooperation and regular communication with the Compliance/Contract Renewal Committee of the Board. Process and Independence The objectives of the Order are to ensure the independent evaluation of the advisory fees paid by the WAT Funds as well as to ensure that all relevant factors are considered. In my view, the contract renewal process has been conducted at arms-length and with independence in gathering, considering and evaluating relevant data. For example, the selection of fund peer groups is critical in assessing a fund's relative performance and cost. I have required Lipper and Morningstar, Inc. to prepare their reports without input or commentary from CWAM; the engagement letters with them reflect this requirement. As a result, the peer groups reflected in the Morningstar, Inc. and Lipper reports were determined independently. After submission of the reports, I asked CWAM to comment on them to avoid errors and to establish a clear record of CWAM's views on which funds, in its judgment, constitute an appropriate peer group. Similarly, I discussed CWAM's profitability analysis with its management but also sought the independent views of Ernst &Young on the reasonableness of CWAM's cost allocation methodology and on the adequacy of the financial data it provided. The evaluation of CWAM's profitability was performed in the context of the limited industry data available. My evaluation of the advisory contract was shaped by my experience as WAT's Chief Compliance Officer ("CCO"). As CCO, I report solely to the Board and have no reporting obligation to or employment relationship with CMG or its affiliates, except for administrative purposes. This too contributes to the independence of this evaluation. I have made several comments on compliance matters in evaluating the quality of service provided by CWAM and CMG. 22 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- Finally, this Report, its supporting materials and the data contained in other materials submitted to the Compliance/Contract Renewal Committee of the Board, in my view, provide a thorough factual basis upon which the Board, in consultation with independent counsel as it deems appropriate, may conduct management fee negotiations that are in the best interests of the WAT Funds' shareholders. * * * VI. Conclusions My review of the data and other material above leads to the following conclusions with respect to the factors identified in the Order. 1. Performance. The WAT Funds generally have achieved outstanding performance and rank very favorably against their peers. The international funds have good recent performance records, but weaker long-term performance relative to the domestic WAT Funds. Recent management changes have been followed by improved performance. The domestic WAT Funds and International Select typically achieve their performance with less risk than their competitors; relative risks are greater for International Small Cap. 2. Management Fees relative to Peers. The management fee rankings of the Funds are generally well below the respective medians and, hence, less favorable to shareholders than their peer group funds. 3. Administrative Fees. The WAT Funds pay a bundled fee that combines advisory fees and administrative expense, so ranking these fees separately was not possible. 4. Management Fees relative to Other Accounts. CWAM's focus is its mutual funds. It does not actively seek to manage separate or institutional accounts. The few institutional accounts it does manage vary in rate structures. Some pay advisory fees commensurate with or higher than the WAT Funds. In a few instances, however, sub-advised accounts pay lower management fees than do the WAT Funds. 5. Costs to CWAM and its Affiliates. CWAM's costs do not appear excessive, and, in my view, it uses appropriate methodologies to allocate overhead costs. CWAM's affiliates do not appear to profit indirectly from CWAM's management agreement with the WAT Funds. 6. Profit Margins. CWAM's firm-wide profit margins are at the upper end of the industry, though these comparisons are hampered by limited industry data. High profit margins are not unexpected for firms that manage large, successful funds and have provided outstanding investment performance for investors. Profit margins for the WAT Funds are lower than the margins for other accounts managed by CWAM because of payments made to intermediaries that offer the WAT Funds through variable annuity products. CMAI, the Funds' administrator, currently experiences losses rather than profits, in connection with its activities relating to the WAT Funds. 7. Economies of Scale. Economies of scale do exist at CWAM and will expand, if the assets of the WAT Funds get larger. They are, however, only partially reflected in the management fee schedule for two of the four WAT Funds. If the Funds' assets continue to grow, under the Funds' current fee schedules, shareholders might not benefit in a manner generally commensurate with CWAM's increased profits 8. Nature and quality of services. This category includes a variety of considerations that are difficult to quantify, yet can have a significant bearing on the performance of the WAT Funds. Several areas merit comment. a. Continuity of Management. It is critical that capable and experienced portfolio managers remain committed to the Funds and are able to hire and retain analysts to assist them. CWAM must have in place appropriate incentive plans that align its management's interests with those of investors. Further, CWAM must maintain the independence of its investment process. It should also be supported by effective information technology. b. Compliance. CWAM has an effective compliance program and a variety of related services that are valuable to shareholders, such as, systems to ensure best execution of portfolio transactions and the daily review of security prices to ensure accuracy of the WAT Funds' NAV. c. Administration Services. The WAT Funds benefit from a variety of administrative services that are performed by CWAM and CMAI, including preparation of registration statements, calculation of Fund NAV's, accounting services, shareholder services, and other functions In my opinion, these conclusions, taken together, generally support the reasonableness of the proposed management agreement. In reaching this conclusion, I weighed heavily the outstanding performance of the WAT Funds relative to their peers. Performance is an investor's first concern. The expense incurred by shareholders to enjoy this performance is, however, high relative to competing funds, though expenses for the WAT Funds are (with one exception) comparable to the parallel Acorn Funds. Nonetheless, a more complete breakpoint schedule could address this issue as well as share with investors more fully the benefits of economies of scale. 23 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- VII. Recommendations The Trustees should consider the following proposals to address the issues identified in this Report. Some of these recommendations require the collection and evaluation of more data. This work cannot be accomplished effectively before the expiration of the existing advisory contract on July 31, 2005. Therefore, I recommend that the Trustees consider extending the existing contract pending consideration of these recommendations. These recommendations do not purport to offer the only avenues to address the opinions and conclusions I have expressed in this Report. Economies of scale, for example, can be addressed in a variety of ways in a management contract. Sound business judgment will guide how any particular area is addressed with due consideration given to all the factors that must be weighed in reaching a management agreement that best serves the WAT Fund shareholders. I believe the Trustees should consider the following: 1. Restructure the management fee schedule beyond the current breakpoints to reflect more fully economies of scale. The Trustees might consider several ways to accomplish this objective, including instituting a two-tier fee structure that incorporates a complex- or CWAM-wide fee (including assets held in separate accounts) and a fund specific fee, with each containing breakpoints to reflect their separate economies of scale. Another approach is to consider uniform breakpoints for all WAT Funds, including breakpoints above and below current asset levels. 2. Conduct further study to ensure that the costs paid to insurance company intermediaries are transparent. The Trustees could consider forming an ad hoc committee to gather and evaluate data regarding CWAM's payments to intermediaries and the services provided by those intermediaries. Such a committee might also seek the assistance of a consultant such as Ernst & Young. 3. Administrative Fees. Administrative and advisory fees could be unbundled to allow greater transparency and to permit distinct comparisons among peers. An administrative fee could also be formulated with a breakpoint schedule that shares the economies of scale available with shareholders. 4. Condition contract renewal on submission of an employment agreements or a management incentive plan designed to ensure the continued employment of senior management, under terms that align management's incentives with the interests of the WAT Funds' shareholders. Any incentive plan should be designed to permit CWAM to attract and retain the highest caliber investment professionals and support them with effective and reliable information technology systems. 5. Review with CWAM its anticipated capacity limitations and the degree to which increased staffing and effective incentives may address those issues. Robert P. Scales Chief Compliance Officer, Senior Vice President and General Counsel July 25, 2005 24 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT The Compliance/Contract Review Committee (the "Committee") of the board of trustees meets on a regular basis and holds special meetings as otherwise necessary or advisable to review the advisory agreement (the "Agreement") of Wanger Advisors Trust (the "Trust") and each series thereof (the "Funds") and determines whether to recommend that the full board approve the continuation of the Agreement for an additional term. The Committee is comprised of three or more trustees, each of whom is an independent trustee, and the Trust's Chief Compliance Officer ("CCO"), who is a non-voting member of the Committee. After the Committee has made its recommendation, the full board, including the independent trustees, determines whether to approve the continuation of the Agreement. In addition, the board, including the independent trustees, considers matters bearing on the Agreement at most of their other meetings throughout the year and meets at least quarterly with the portfolio managers employed by Columbia Wanger Asset Management, L.P. ("CWAM"), the Funds' investment adviser. The trustees receive all materials that they and CWAM believe to be reasonably necessary for them to evaluate the Agreement and determine whether to approve the continuation of the Agreement. Those materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and of the Funds' performance benchmarks, (ii) information on the Funds' advisory fees and other expenses, including information comparing the Funds' expenses to those of peer groups of funds and information about any applicable expense caps and fee "breakpoints," (iii) share sales and redemption data, (iv) information about the profitability to CWAM and its affiliates of their relationships with the Funds and potential "fall-out" or ancillary benefits that CWAM and its affiliates may receive as a result of their relationships with the Funds and (v) information obtained through CWAM's response to a questionnaire prepared at the request of the trustees by Bell, Boyd & Lloyd LLC, independent counsel to the Trust and to the independent trustees. The trustees may also consider other information such as (i) CWAM's financial results and financial condition, (ii) each Fund's investment objective and strategies and the size, education and experience of CWAM's investment staff and their use of technology, external research and trading cost measurement tools, (iii) the allocation of the Funds' brokerage, if any, including allocations to brokers affiliated with CWAM, and the use of "soft" commission dollars to pay Fund expenses or to pay for research products and services, (iv) the resources devoted to, and the record of compliance with, the Funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (v) the response of CWAM and its affiliates to various legal and regulatory proceedings since 2003 and (vi) the economic outlook generally and for the mutual fund industry in particular. In addition, the trustees conferred with, and reviewed the Management Fee Evaluation prepared by, the Trust's Senior Officer, who was appointed by the trustees as contemplated by the Assurance of Discontinuance dated February 9, 2005 among affiliates of CWAM and the Office of the New York Attorney General. A summary of the Management Fee Evaluation is included in this report. Throughout the process, the trustees have the opportunity to ask questions of and request additional materials from CWAM. On July 25, 2005 the board of trustees most recently approved the continuation of the Agreement through October 31, 2005, and on September 28, 2005 the board approved an amended and restated Agreement (the "Amended Agreement") for an initial term ending on July 31, 2006. The board actions followed Committee meetings held in June, July and September 2005. The board determined in the first instance to continue the Agreement through October (rather than for a full year period) pending the resolution of the compensation and incentive plan for key CWAM employees, whose employment agreements were to terminate in December, 2005. Those matters were resolved prior to September 28, 2005. In considering whether to approve the continuation of the Agreement and to approve the Amended Agreement, the trustees, including the independent trustees, did not identify any single factor as determinative, and each weighed the various factors as he or she deemed appropriate. The trustees considered the following matters in connection with their continuation of the Agreement and, except as noted in connection with their approval of the Amended Agreement (collectively with the Agreement, the "Agreements"). Nature, quality and extent of services. The trustees reviewed the nature, quality and extent of CWAM's services to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge gained from the board's regular meetings with management. In addition, the trustees reviewed CWAM's resources and key personnel, especially those who provide investment management services to the Funds. The trustees considered the importance of the continuity of management. At the September 28, 2005 meeting, the trustees considered the fact that Columbia Management Group, Inc. ("CM") and CWAM had agreed on a new compensation and incentive plan for key CWAM employees. The trustees also considered other services provided to the Funds by CWAM, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, providing support services for the board and board committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various Fund policies and procedures and with applicable securities laws and regulations. The trustees concluded that the nature and extent of the services provided by CWAM to each Fund were appropriate and consistent with the terms of the Agreements, that the quality of those services had been consistent with or superior to quality norms in the industry and that the Funds were likely to benefit from the continued provision of those services. They also concluded that CWAM had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. Performance of the Funds. The trustees considered the short-term and longer-term performance of each Fund. They reviewed information comparing each Fund's performance with the performance of the Fund's benchmark and with the performance of comparable funds and peer groups identified by Lipper Inc. ("Lipper") and Morningstar Associates, LLC ("Morningstar"). They noted that the two domestic Funds, Wanger U.S. Smaller Companies and Wanger Select, have each outperformed their respective benchmarks and Lipper and Morningstar peers. The trustees considered that Lipper and Morningstar ranked Wanger U.S. Smaller Companies first in its peer group for the past five years and Wanger Select first in its peer group for the three and five-year periods. The trustees discussed the performance of the two international Funds, Wanger International Small Cap and Wanger International Select, noting that each Fund's performance had improved over the past two years. They considered that Morningstar ranked Wanger International Small Cap first in its peer group for the one-year period and Lipper ranked it first in its peer group for the three-year period. They also considered that Lipper ranked Wanger International Select first in its peer group for the one-year period and second in its peer group for the three and five-year periods. The trustees concluded that although past performance is not necessarily indicative of future results, the Funds' improving performance record and investment process enhancements were important factors in the trustees' evaluation of the quality of services provided by CWAM under the Agreement. Costs of Services and Profits Realized by CWAM. The trustees examined information on fees and expenses of each Fund in comparison to information for other comparable funds as provided by Lipper and Morningstar. They considered that both the contractual rates of advisory fees and the actual advisory fees for most of the Funds were higher than the median advisory fees of the respective peer groups. The trustees also considered that the expense ratios of each Fund were also higher than the median expense ratios of the respective peer groups. At the July 25, 2005 meeting, at the recommendation 25 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT of the Committee, the board approved a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above, effective August 1, 2005. The trustees reviewed information on the profitability of CWAM in serving as each Fund's investment adviser and of CWAM and its affiliates in all of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other business units. The trustees considered the methodology used by CWAM in determining compensation payable to portfolio managers and the very competitive environment for investment management talent. The trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and profitability of any manager is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the manager's capital structure and cost of capital. However, based on the information available and taking those factors into account, the trustees concluded that the profitability of CWAM regarding each Fund in relation to the services rendered was not unreasonable. The trustees also reviewed CWAM's advisory fees for its institutional separate accounts. Although in most instances its institutional separate account fees for various investment strategies were lower than the advisory fees charged to the Funds with corresponding strategies, the trustees noted that CWAM performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the trustees considered the financial condition of CWAM, which they found to be sound. The trustees concluded that the advisory fees (including the additional breakpoint for Wanger International Small Cap) and other compensation payable by the Funds to CWAM and its affiliates were reasonable in relation to the nature and quality of the services to be provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees CWAM charges to other clients. The trustees noted, however, that they would continue to evaluate the Funds' investment advisory fee rates. The trustees also concluded that the Funds' estimated overall expense ratios, taking into account quality of services provided by CWAM and the investment performance of the Funds, were also reasonable. Economies of Scale. The trustees noted that the advisory fee schedule for each of Wanger U.S. Smaller Companies and Wanger International Small Cap contains two breakpoints that reduce the fee rate on assets above specified levels. They also noted that they had agreed to establish a new breakpoint for Wanger International Small Cap. The trustees concluded that with the additional breakpoint for Wanger International Small Cap, the fee schedule for each Fund would represent a sharing of economies of scale at current asset levels. They agreed, however, to continue their periodic consideration of the Funds' fee structures and economies of scale. Other Benefits to CWAM. The trustees also considered benefits that accrue to CWAM and its affiliates from their relationship with the Funds. The trustees concluded that, other than the services to be provided by CWAM and its affiliates pursuant to the Agreement and the fees payable by the Funds therefor, the Funds and CWAM may potentially benefit from their relationship with each other in other ways. Recognizing that an affiliate of CWAM serves the Funds as transfer agent and receives compensation from the Funds for those services, the trustees determined that such compensation was not unreasonable. They noted that the Funds' transfer agent reported that it made a small profit on its work for the Funds. The trustees also considered CWAM's use of commissions to be paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting the Funds and/or other clients of CWAM. The trustees concluded that CWAM's use of "soft" commission dollars to obtain research products and services was consistent with regulatory requirements and is beneficial to the Funds. They concluded that, although CWAM derives or may derive additional benefits through the use of soft dollars from the Funds' portfolio transactions, the Funds also benefit from the receipt of research products and services to be acquired through commissions paid on the portfolio transactions of other clients of CWAM. New Terms of the Amended Agreement. As previously mentioned, the trustees negotiated a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above. That new breakpoint is reflected in the Amended Agreement. In addition, the Amended Agreement includes representations by CWAM that are substantially similar to those contained in a letter agreement between the Trust and CM that expired on October 31, 2005. The Amended Agreement provides that: (1) CWAM will endeavor to preserve the autonomy of the Trust; (2) CWAM remain a wholly owned subsidiary of CM (or any successor company) as a Chicago-based management firm; (3) CWAM will maintain the investment philosophy and research that the Chicago-based management deems appropriate, research activities separate and dedicated solely to CWAM and its own domestic and international trading activities; (4) CWAM will use its best efforts to maintain information systems that will provide timely and uninterrupted operating information and data consistent with all regulatory and compliance requirements; (5) CWAM's Chicago-based management will have the responsibility and considerable latitude to recruit and compensate (on a competitive basis) investment management personnel and to control travel budgets for analysts consistent with its operational and strategic plans while subject to the approval of CM; and (6) CWAM acknowledges the importance that the Board and its compliance/contract review committee place on full legal and regulatory compliance by CMG, CWAM, and all other Trust service providers and their personnel (collectively, "Providers") and agrees to (i) cooperate fully with the Board, the compliance/contract review committee and the CCO of the Trust with all inquiries by the Trust concerning such compliance by the Providers and (ii) communicate proactively with the Board, the compliance/contract review committee and the CCO of the Trust concerning material compliance matters and any instance of legal or regulatory non-compliance by the Providers of which CWAM is aware and that CWAM deems to be material. Such cooperation and communication by CWAM will be done after receipt of an inquiry or upon learning of any such legal or regulatory non-compliance. Lastly, the Amended Agreement provides that the principal investment management focus and responsibilities of CWAM's portfolio managers and analysts will be dedicated to the Trust and Columbia Acorn Trust. After full consideration of the above factors as well as other factors that were instructive in analyzing the Agreement, the trustees, including all of the independent trustees, concluded that the continuation of the Agreement was in the best interest of each Fund. On July 25, 2005, the trustees continued the Agreement, as revised to include an additional breakpoint for Wanger International Small Cap, through October 31, 2005, and on September 28, 2005, the trustees approved the Amended Agreement. 26 Wanger U.S. Smaller Companies 2005 Annual Report - -------------------------------------------------------------------------------- SPECIAL NOTICE A special meeting of the shareholders was held on November 30, 2005 for the purpose of electing nine trustees.

Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- UNDERSTANDING YOUR EXPENSES As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. ANALYZING YOUR FUND'S EXPENSES To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in the fund during the reporting period. The information in the following table is based on an initial investment of $1,000.00, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using actual operating expenses and total return for the fund. The amount listed in the "hypothetical" column assumes that the return each year is 5% before expenses and then applies each Fund's actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the reporting period. See the "Compare with other funds" information for details on using the hypothetical data. ESTIMATING YOUR ACTUAL EXPENSES To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period. 1. Divide your ending account balance by $1,000.00. For example, if an account balance was $8,600.00 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your fund. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. July 1, 2005 - December 31, 2005 - ------------------------------------------------------------------------------------------------------------------------------------ Account value at the Account value at the Expenses paid during Fund's annualized beginning of the period ($) end of the period ($) the period ($) expense ratio (%)* - ------------------------------------------------------------------------------------------------------------------------------------ Actual Hypothetical Actual Hypothetical Actual Hypothetical - ------------------------------------------------------------------------------------------------------------------------------------ Wanger International Small Cap 1,000.00 1,000.00 1,170.39 1,019.41 6.29 5.85 1.15 - ------------------------------------------------------------------------------------------------------------------------------------ Expenses paid during the period are equal to the fund's annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the investment adviser not waived a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund. As a shareholder of the fund, you do not incur any transaction costs, such as sales charges, redemption or exchange fees. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate account. The hypothetical example provided is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds whose shareholders may incur transaction costs. *For the six months ended 12/31/05. COMPARE WITH OTHER FUNDS Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transactional costs, such as sales charges or redemption or exchange fees, that may be incurred by shareholders of other funds. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. 1 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- [graphic: squirrel] NO ORDINARY PORTFOLIO MANAGERS I began working with Ralph Wanger, founder of Columbia Wanger Asset Management, in 1978. Shortly thereafter he issued the third quarter shareholder report for one of our retail funds. In it he wrote: "...hedonism is in... Let us explore the possibility that we have been going through the oldest cycle of all--from Good to Bad." In order to prove that badness was more profitable than goodness, Ralph tested two portfolios for 36-month price changes. The virtuous portfolio included Angelica, up 45%, and Church's Fried Chicken, up 520%. The wicked portfolio included Playboy, up 600%, and DeBeers Mines, up 59%.1 The wicked portfolio won. Ralph's footnote to his essay read: "This study was done by the usual techniques of Financial Analysis: (A) The stocks chosen had nothing to do with the subject, and (B) The portfolios were readjusted until the answer affirmed the hypothesis." At that point it became very clear to me that Ralph Wanger was no ordinary portfolio manager! Ralph parlayed his legendary shareholder reports into his book, A Zebra in Lion Country.2 The book could have been titled, The Wit and Wisdom of Ralph Wanger. In it Ralph admits that his first quarterly newsletters were serious and stuffy. He said that he gave market and economic forecasts that quickly became outdated. Then he decided, "If most mutual fund communications are both boring and wrong, well then, I figured, I'd rather be lively and wrong." There's a lot of Wisdom in A Zebra in Lion Country. Examples include: "Look for stocks that have basic value but are out of fashion." Ralph also wrote, "The greatest investment profit comes when an ugly duckling becomes a swan." And, "If a company's earnings beat the Merrill Lynch analyst's forecast by 2 cents, that doesn't excite me. I need a long-term reason to own a stock." And Ralph meant long term. "...you can't make five or ten or twenty times your money if you don't hold on to your stocks. Most people are delighted when a stock doubles, and quickly sell to lock in their gain," he wrote in his book. Ralph's long-term thinking was driven home in a report essay he wrote in June 1992: "What really makes for successful investing is having a few enormous hits. In 22 years, I've really had three Super Stocks." Houston Oil & Minerals was one. Houston Oil cost $220,000 in 1973 and went to $5.3 million in 1977. Another was Cray Research, which cost $1.5 million in 1978 and was worth $20 million in 1985. International Game Technology, a maker of slot machines, cost $5 million in 1988 and was worth $80 million by June 1992.3 Ralph also had his share of disasters. He wrote in that 1992 report, "There is one stock we tried to sell for two years and never got a bid on any of it. A stock like that just slides from 4 to 3 to 2 to 1 and finally disappears..." Ralph said, "It's kind of like a doctor saying don't worry about it, it's just going to shrivel up and fall off." Atchison Casting, an owner of steel foundries, was a painful example of this. Ralph began purchasing the stock in 1994 and it ended up being nearly worthless when it was sold in 2003. The wisdom here is that small-cap investing can be a winner's game. Let your winners run. On any individual stock, one can possibly make several thousand percent, but the most that one can lose is 100%. Small-cap investors will have some big percentage losers, but damage to portfolios can be minor as long as investors don't keep throwing money at them and if they maintain a well-diversified portfolio. How did Ralph use his genius and wisdom to build a successful firm? A few years after I joined Ralph we had a heated discussion about a stock. The next day I asked him if I had crossed the line during our debate. He looked at me kind of puzzled and said, course not, if we always agreed, why would I need you?" Ralph always respected differing opinions and created a culture of intellectual freedom. In an investment world full of wishful thinking, Ralph also demanded intellectual honesty. The ability to ask tough questions, get sound answers, discover good businesses, detect strong managers and then value stocks appropriately, requires intellectual honesty. Then it's time to act. I remember an analyst saying that a stock trades by appointment and Ralph responding, "Then make an appointment and buy it!" The culture that Ralph fostered allowed Columbia Wanger Asset Management to grow and helped its shareholders to prosper. Leah Zell's contribution to Columbia Wanger Asset Management has also been huge and complementary to Ralph's. Leah seemed to have the ability to see around corners strategically and make quick, good decisions. When Leah joined our team in 1984, she began as a domestic analyst following mostly real estate and retail stocks. Leah then became our first foreign analyst. She successfully launched our first international retail mutual fund, Acorn International, realizing great investment results, and taking the Fund from zero to one billion dollars in assets under management in 14 months. Of course, she could not have done it without a team. Leah built the international area at Columbia Wanger Asset Management. International investing requires all the skills needed for domestic investing, and more. At Columbia Wanger, we like to hire international analysts who also have language skills and cultural 2 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- knowledge. In a number of cases, Leah successfully mentored new analysts who had these traits and fine financial skills but had a lot to learn about security analysis. We at Columbia Wanger Asset Management are happy that Ralph and Leah kept their offices with us and have been advisors over the last two years. We've gotten good advice, but Ralph and Leah made it clear that the decisions were ours. In our semiannual report we published Ralph's last column, which appeared in this section. Ralph once said of writing his essays, "It is fun for me and only mildly irritating to our shareholders." We are grateful to have had Ralph's and Leah's presence and wisdom for all these years. On September 30, 2005, they retired from their advisory roles with the firm. DOMESTIC SMALL-CAP CYCLE Small caps have outperformed large caps for over six years now; by our reckoning, small caps bottomed vs. large caps in March 1999. The small-cap Russell 2500 Index returned 110% from that date through December 31, 2005, far outpacing the S&P 500, which returned 8%. In the past, small-cap stocks had long cycles of out- and under-performance vs. large caps. There is no science and there is no magic in predicting the exact top of a small-cap cycle. Perhaps small caps will continue to outperform--some believe small caps will outperform as long as rapid earnings growth continues and some others believe outperformance will persist until the overall market turns. Numerous economists are predicting higher inflation rates, and small caps did relatively well during the inflationary periods of the 1970s. However, when looking at price-to-earnings ratios, small caps appear expensive vs. large caps. Using another measure, price-to-book value, small caps appear somewhat more reasonably priced. While we don't think domestic small caps are back to their all-time relative high valuations, we do think small-cap domestic stocks on average are no longer cheap. We do not predict market cycles. We stick to what we believe we do best: buying reasonably priced small- and mid-cap stocks and when they enter periods of higher valuations, we try to become more selective. Over time this consistently applied approach has weathered the Funds through a variety of market cycles. While we certainly can't predict what the future holds, the best defense against unknown market factors is diversification across assets, which is a prudent and time-tested investment strategy. COLUMBIA WAM NEWS We are pleased to announce that Satoshi Matsunaga has joined our international analyst team covering Japan. He came on board in September.

Wanger International Small Cap ended 2005 up 21.53%, trailing the 21.99% gain of the S&P/Citigroup EMI Global ex-US Index by a narrow margin. Fund underperformance was largely due to an underweight in a rallying Japanese market. When we find ideas that meet our return requirements and other investment criteria, we intend to continue adding to the Fund's weighting in Japanese holdings. We believe Japanese market fundamentals are improving and valuations are generally reasonable. Wanger International Small Cap benefited from a number of winners in the energy sector. Perusahaan Gas Negara, an Indonesian pipeline operator, posted a 232% return in the year thanks to the Indonesian government's decision to deregulate natural gas prices earlier than expected. France's Vallourec, a seamless tube manufacturer supplying energy producers, was up nearly 285% on strong volumes and favorable pricing. UK oil and gas producer Tullow Oil gained 71% due to increased demand and rising energy prices. Winners outside of the energy sector included Japanese parking lot operator Park 24, up 102% in the year. While Japan was among the best performing markets in 2005, Park 24 was also a beneficiary of favorable regulatory changes affecting its core parking-lot business. Sweden's Hexagon, a manufacturer of measurement equipment and polymers, had a 91% gain in the year. In 2005 Hexagon launched its new metrology operating system, strongly boosting margin and profits while demonstrating a successful shift from equipment to software supplier. Also, Hexagon acquired leading metrology peer Leica which should provide above average profit growth over the next two years. Laggards for the year included Business Post Group, a UK parcel and express mail service company that fell 53% on declining volumes and rising costs. Hong Kong's Global Bio-Chem Technology Group, a refiner of corn-based commodities, dropped 32% on price weakness in some key commodities. Ulster Television, a television and radio station operator in Ireland, fell 22% as investors were concerned about a large acquisition the company made in the United Kingdom. Small-cap international stocks have had a very good run over the last few years. Share price appreciation has been driven by a combination of improving company earnings and higher valuations assigned by the market to those earnings. As a consequence, this group of stocks does not appear to be cheap. We nonetheless continue to find what we believe to be good companies around the world with attractive fundamentals not yet fully reflected in their share prices. On December 7, 2005, Louis Mendes was named co-manager of this Fund.

DUE TO ONGOING MARKET VOLATILITY, PERFORMANCE IS SUBJECT TO SUBSTANTIAL SHORT-TERM FLUCTUATIONS. Wanger International Small Cap is a diversified fund that invests primarily in the stocks of non-U.S. companies with capitalizations of less than $5 billion at the time of initial purchase. Smaller company stocks are often more volatile or less liquid than the stocks of larger companies. 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. PERFORMANCE SHOWN HERE IS PAST PERFORMANCE, WHICH CANNOT GUARANTEE FUTURE RESULTS. CURRENT PERFORMANCE MAY BE HIGHER OR LOWER. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PERFORMANCE CHANGES OVER TIME. CURRENT RETURNS FOR THE FUND MAY BE DIFFERENT THAN THAT SHOWN. FOR MONTHLY PERFORMANCE UPDATES, PLEASE CONTACT US AT 1-888-4-WANGER. - -------------------------------------------------------------------------------- RESULTS TO DECEMBER 31, 2005 4th quarter 1 year WANGER INTERNATIONAL SMALL CAP 4.97% 21.53% S&P/Citigroup EMI Global ex-US 6.67 21.99 MSCI EAFE 4.08 13.54 Lipper International Small Cap Funds Index 6.23 23.77 NAV AS OF 12/31/05: $30.63 PERFORMANCE NUMBERS REFLECT ALL FUND EXPENSES BUT DO NOT INCLUDE ANY INSURANCE CHARGE IMPOSED BY YOUR INSURANCE COMPANY'S SEPARATE ACCOUNTS.

See accompanying notes to financial statements. 15 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 1. NATURE OF OPERATIONS Wanger International Small Cap (the "Fund"), is a series of Wanger Advisors Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of the Fund is to seek long-term growth of capital. The Fund is available only for allocation to certain life insurance company separate accounts established for the purpose of funding qualified and non-qualified variable annuity contracts, and variable life insurance policies and may also be offered directly to certain types of pension plans and retirement arrangements. 2. SIGNIFICANT ACCOUNTING POLICIES SECURITY VALUATION Securities of the Fund are valued at market value or, if a market quotation for a security is not readily available or is deemed not to be reliable because of events or circumstances that have occurred between the market quotation and the time as of which the security is to be valued, the security is valued at a fair value determined in accordance with procedures established by the Board of Trustees. 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 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. Short-term debt obligations 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 readily available and any other assets are valued as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. The Trust has retained an independent statistical fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchanges and the time at which fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security. REPURCHASE AGREEMENTS The Fund may engage in repurchase agreement transactions. The Fund, through its custodians, 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 repurchase price including interest. 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 Fund. Interest income is recorded on the accrual basis and includes amortization of discounts on short-term debt obligations and on long-term debt obligations when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. RESTRICTED SECURITIES Restricted securities are securities that may only be resold upon registration under federal securities laws or in transactions exempt from registration. In some cases, the issuer of restricted securities has agreed to register such securities for resale at the issuer's expense either upon demand by the Fund or in connection with another registered offering of the securities. Many restricted securities may be resold in the secondary market in transactions exempt from registration. Such restricted securities may be determined to be liquid under criteria established by the Board of Trustees. The Fund will not incur any registration costs upon such resale. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. 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 ("the Exchange") on each day the Exchange is open for trading by dividing the total value of the Fund's investments and other assets, less liabilities, by the number of Fund shares outstanding. CUSTODY FEES/CREDITS Custody fees are reduced based on the Fund's cash balances maintained with the custodian. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered in to such an agreement. The amount is disclosed as a reduction of total expenses in the Statement of Operations. INDEMNIFICATION In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Trust's organizational documents, the Trustees and Officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these warranties and indemnities to be minimal. FEDERAL INCOME TAXES The Fund has complied with the provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distribute all its 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. FOREIGN CAPITAL GAINS TAXES Realized gains in certain countries may be subject to foreign taxes at the fund level, at rates ranging from 10%-15%. The Fund accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction. DISTRIBUTIONS TO SHAREHOLDERS Distributions to shareholders are recorded on the ex-date. 16 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 3. FEDERAL TAX INFORMATION The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund's capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2005, permanent book and tax basis differences resulting primarily from differing treatments for foreign currency transactions were identified and reclassified among the components of the Fund's net assets as follows: UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED INCOME LOSS PAID-IN CAPITAL -------------- ------------- --------------- $(521,186) $521,186 $-- Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. The tax character of distributions paid during the year ended December 31, 2005 was as follows: DECEMBER 31, 2005 DECEMBER 31, 2004 ----------------- ----------------- Distributions paid from: Ordinary Income* $6,966,978 $2,991,364 * For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of December 31, 2005, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM NET UNREALIZED INCOME CAPITAL GAINS APPRECIATION* ------------- -------------- -------------- $6,365,890 $-- $272,538,139 * The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales, foreign currency transactions and passive foreign investment company ("PFIC") adjustments. The following capital loss carryforwards, determined as of December 31, 2005, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: YEAR OF CAPITAL LOSS EXPIRATION CARRYFORWARDS - ---------- ------------- 2010 $4,559,033 2011 2,734,494 ---------- Total $7,293,527 Expired capital loss carryforwards, if any, are recorded as a reduction of paid in capital. Capital loss carryforwards of $49,979,639 were utilized during the year ended December 31, 2005 for the Fund. 4. TRANSACTIONS WITH AFFILIATES Columbia Wanger Asset Management, L.P., ("Columbia WAM") a wholly owned subsidiary of Columbia Management, Inc. (CM), which in turn is an indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), furnishes continuing investment supervision to the Fund and is responsible for the overall management of the Fund's business affairs. Effective August 1, 2005, under the fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below: AVERAGE DAILY NET ASSETS ANNUAL FEE RATE For the first $100 million 1.15% Next $150 million 1.00% Next $250 million 0.95% In excess of $500 million 0.85% Effective March 8, 2005 through July 31, 2005, under the Fund's investment management agreement, fees were accrued daily and monthly to Columbia WAM at the annual rates shown in the table below. AVERAGE DAILY NET ASSETS ANNUAL FEE RATE For the first $100 million 1.15% Next $150 Million 1.00% In excess of $250 million 0.95% Prior to March 8, 2005, under the Fund's investment management agreement, fees were accrued daily and paid monthly to Columbia WAM at the annual rates shown in the table below: AVERAGE DAILY NET ASSETS ANNUAL FEE RATE For the first $100 million 1.30% Next $150 million 1.20% In excess of $250 million 1.10% In accordance with the terms of the Assurance of Discontinuance with the New York Attorney General, Columbia WAM waived a portion of the fees payable under the Fund's investment management agreement so that those fees were retained at the following annual rates as a percent of average daily net assets: 1.15% - up to $100 million; 1.00% - $100 million to $250 million; 0.95% - $250 million and over. The fee waiver was effective from January 1, 2005 though March 8, 2005, but applied as if it had gone into effect on December 1, 2004. Fees waived by Columbia WAM amounted to $188,761 for the year ended December 31, 2005. The investment advisory agreement also provides that through April 30, 2005 Columbia WAM will reimburse the Fund to the extent that ordinary operating expenses (computed based on net custodian fees) exceed an annual percentage of 2.00% of average daily net assets. There was no reimbursement for the year ended December 31, 2005. For the year ended December 31, 2005, the Fund's annualized the effective investment advisory fee rate was 0.95%. 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. For the year ended December 31, 2005, the Fund paid $69,728 to trustees not affiliated with Columbia WAM. The Board of Trustees appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. These expenses are disclosed separately as "Compliance fees" on the Statement of Operations. Columbia Management Distributors, Inc. (formerly Columbia Funds Distributor, Inc.), a wholly owned subsidiary of BOA, serves as the principal underwriter of the Trust and receives no compensation for its services. 17 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS Columbia Management Services, Inc. (formerly Columbia Funds Services, Inc.) (the "Transfer Agent") a wholly-owned subsidiary of BOA, provides shareholder services to the Fund and has subcontracted with Boston Financial Data Services ("BFDS") to serve as subtransfer agent. For such services, the Transfer Agent receives a fee, paid monthly, at the annual rate of $21.00 per open account. The Transfer Agent also receives a reimbursement for certain out-of-pocket expenses. An affiliate may include any company in which a fund owns five percent or more of its outstanding voting shares. On December 31, 2005, the Fund held five percent or more of the outstanding voting securities of one or more companies. Details of investments in those affiliated companies are presented on page 11. During the year ended December 31, 2005, the Fund engaged in purchases and sales transactions with funds that have a common investment advisor (or affiliated investment advisors), common Directors/Trustees, and/or common Officers. These purchase and sale transactions complied with the provisions of Rule 17a-7 under the Investment Company Act of 1940 and were $8,568,216 and $0, respectively. 5. BORROWING ARRANGEMENTS The Trust participates in a $150,000,000 credit facility, which was entered into to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. No amounts were borrowed under this facility for the year ended December 31, 2005. 6. FUND SHARE TRANSACTIONS Proceeds and payments on Fund shares as shown in the statement of changes in net assets are in respect of the following numbers of shares: Year ended Year ended December 31, 2005 December 31, 2004 - -------------------------------------------------------------------------------- Shares sold 9,532,675 8,009,022 Shares issued in reinvestment of dividend distributions 252,061 140,969 - -------------------------------------------------------------------------------- Less shares redeemed 1,842,378 3,663,834 Net increase in shares outstanding 7,942,358 4,486,157 - -------------------------------------------------------------------------------- 7. INVESTMENT TRANSACTIONS The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2005 were $426,617,067 and $172,502,988. 8. LEGAL PROCEEDINGS Columbia WAM, Columbia Acorn Trust, another mutual fund family advised by Columbia WAM, and the trustees of Colombia Acorn Trust, are named as defendants in class and derivative complaints which have been consolidated in a Multi-District Action in the federal district court for the District of Maryland. These lawsuits contend that defendants permitted certain investors to market time their trades in certain Columbia Acorn Funds. The Multi-District Action is ongoing. However, all claims against Columbia Acorn Trust and the independent trustees of Columbia Acorn Trust have been dismissed. Columbia WAM, the Columbia Acorn Funds and the trustees of Columbia Acorn Trust are defendants in a consolidated lawsuit filed in the federal district court of Massachusetts alleging that Columbia WAM used Fund assets to make undisclosed payments to brokers as an incentive for the brokers to market the Columbia Acorn Funds over the other mutual funds to investors. The complaint alleges Columbia WAM and the Trustees of the Trust breached certain common laws duties and federal laws. All claims against all defendants in this lawsuit have been dismissed. However, the plaintiffs have filed a notice of appeal with the First Circuit Court of Appeals. The Columbia Acorn Trust and Columbia WAM are also defendants in a class action lawsuit that alleges, in summary, that the Columbia Acorn Trust and Columbia WAM exposed shareholders of Columbia Acorn International to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of that Fund's securities had occurred after foreign markets had closed but before the calculation of the Funds' net asset value ("NAV"); (b) failing to implement the Fund's portfolio valuation and share pricing policies and procedures; and (c) failing to know and implement applicable rules and regulations concerning the calculation of NAV (the "Fair Valuation Lawsuit"). The Seventh Circuit ruled that the plaintiffs' state law claims were preempted under federal law resulting in the dismissal of plaintiffs' complaint. However, plaintiffs are in the process of appealing that decision before the United States Supreme Court. On March 21, 2005, a class action complaint was filed against the Columbia Acorn Trust and Columbia WAM seeking to rescind the Contingent Deferred Sales Charges assessed upon redemption of Class B shares of Columbia Acorn Funds due to the alleged market timing of the Columbia Acorn Funds. In addition to the rescission of sales charges, plaintiffs seek recovery of actual damages, attorneys' fees and costs. The case has been transferred to the Multi-District Action in the federal district court of Maryland. The Columbia Acorn Trust and Columbia WAM intend to defend these suits vigorously. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Funds. In connection with the events described in detail above, various parties have filed suit against certain funds, their Boards and/or BOA (and affiliated entities). These suits are ongoing. However, based on currently available information, the Columbia Acorn Trust believes that the likelihood that these lawsuits will have a material adverse impact on any fund is remote, and Columbia WAM believes that the lawsuits are not likely to materially affect its ability to provide investment management services to the Funds. For the year ended December 31, 2005, CM has assumed $135,829 in consulting services and legal fees incurred by the Fund in connection with these matters. 18 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of Wanger International Small Cap Fund: In our opinion, the accompanying statement of assets and liabilities, including the statement of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Wanger International Small Cap Fund (a series of the Wanger Advisors Trust, hereinafter referred to as the "Fund") at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at December 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for the periods ended December 31, 2003 and prior were audited by other independent auditors whose report dated February 6, 2004 expressed an unqualified opinion on those financial statements. PricewaterhouseCoopers LLP Chicago, Illinois February 14, 2006 19 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- [EXCERPTS FROM:] WANGER ADVISORS TRUST Management Fee Evaluation of the Senior Officer Prepared Pursuant to the New York Attorney General's Assurance of Discontinuance July 2005 20 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- Introduction The New York Attorney General's Assurance of Discontinuance ("Order") entered into by Columbia Management Advisors, Inc. ("CMAI") and Columbia Funds Distributor, Inc., ("CFDI" and collectively with "CMAI," "CMG") in February 2005, allows CMAI to manage or advise a mutual fund, including the Wanger Advisors Trust's family of funds (the "WAT Funds" or "WAT" or "Trust"), only if the trustees of the WAT Funds appoint a "Senior Officer" to perform specified duties and responsibilities. One of these responsibilities includes "managing the process by which proposed management fees (including but not limited to, advisory fees) to be charged the WAT Fund[s] are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." The Order also provides that the Board of Trustees of the WAT Funds ("Board") must determine the reasonableness of proposed "management fees" by using either an annual competitive bidding process supervised by the Senior Officer or Independent Fee Consultant, or by obtaining "an annual independent written evaluation prepared by or under the direction of the Senior Officer or the Independent Fee Consultant." "Management fees" are only part of the costs and expenses paid by mutual fund shareholders. The expenses can vary depending upon the class of shares held but usually include: (1) investment management or advisory fees to compensate analysts and portfolio managers for stock research and portfolio management, as well as the cost of operating a trading desk; (2) administrative expenses incurred to prepare registration statements and tax returns, calculate the Funds' net asset values, maintain effective compliance procedures and perform recordkeeping services; (3) transfer agency costs for establishing accounts, accepting and disbursing funds, as well as overseeing trading in Fund shares; (4) custodial expenses incurred to hold the securities purchased by the Funds; and (5) distribution expenses, including commissions paid to brokers that sell the Fund shares to investors. Columbia Wanger Asset Management, L.P. ("CWAM"), the adviser to the WAT Funds, has proposed that the Trust enter into an agreement that "bundles" the first two categories listed above: advisory and administrative services. The fees paid under this agreement are referred to as "management fees." Other fund expenses are governed by separate agreements, in particular agreements with two CWAM affiliates: CFDI, the broker-dealer that underwrites and distributes the WAT Funds' shares, and Columbia Funds Services, Inc. ("CFSI"), the Funds' transfer agent. In conformity with the terms of the Order, this evaluation, therefore, addresses only the advisory and administrative contract between CWAM and the Trust, and does not extend to the other agreements. According to the Order, the Senior Officer's evaluation must consider at least the following: (1) Management fees (including components thereof) charged to institutional and other clients of CWAM for like services; (2) Management fees (including any components thereof) charged by other mutual fund companies for like services; (3) Costs to CWAM and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; (4) Profit margins of CWAM and its affiliates from supplying such services; (5) Possible economies of scale as the WAT Funds grow larger; and (6) The nature and quality of CWAM's services, including the performance of each WAT Fund. On November 17, 2004, the Board appointed me, Robert Scales, Senior Officer under the Order. The Board also determined not to pursue a competitive bidding process and instead, charged me with the responsibility of evaluating the WAT Funds' proposed advisory and administrative fee contract with CWAM in conformity with the requirements of the Order. This Report is an annual evaluation required under the Order. In discharging their responsibilities, the independent Trustees have also consulted independent, outside counsel. * * * This evaluation was performed in cooperation and regular communication with the Compliance/Contract Renewal Committee of the Board. Process and Independence The objectives of the Order are to ensure the independent evaluation of the advisory fees paid by the WAT Funds as well as to ensure that all relevant factors are considered. In my view, the contract renewal process has been conducted at arms-length and with independence in gathering, considering and evaluating relevant data. For example, the selection of fund peer groups is critical in assessing a fund's relative performance and cost. I have required Lipper and Morningstar, Inc. to prepare their reports without input or commentary from CWAM; the engagement letters with them reflect this requirement. As a result, the peer groups reflected in the Morningstar, Inc. and Lipper reports were determined independently. After submission of the reports, I asked CWAM to comment on them to avoid errors and to establish a clear record of CWAM's views on which funds, in its judgment, constitute an appropriate peer group. Similarly, I discussed CWAM's profitability analysis with its management but also sought the independent views of Ernst &Young on the reasonableness of CWAM's cost allocation methodology and on the adequacy of the financial data it provided. The evaluation of CWAM's profitability was performed in the context of the limited industry data available. My evaluation of the advisory contract was shaped by my experience as WAT's Chief Compliance Officer ("CCO"). As CCO, I report solely to the Board and have no reporting obligation to or employment relationship with CMG or its affiliates, except for administrative purposes. This too contributes to the independence of this evaluation. I have made several comments on compliance matters in evaluating the quality of service provided by CWAM and CMG. 21 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- Finally, this Report, its supporting materials and the data contained in other materials submitted to the Compliance/Contract Renewal Committee of the Board, in my view, provide a thorough factual basis upon which the Board, in consultation with independent counsel as it deems appropriate, may conduct management fee negotiations that are in the best interests of the WAT Funds' shareholders. * * * VI. Conclusions My review of the data and other material above leads to the following conclusions with respect to the factors identified in the Order. 1. Performance. The WAT Funds generally have achieved outstanding performance and rank very favorably against their peers. The international funds have good recent performance records, but weaker long-term performance relative to the domestic WAT Funds. Recent management changes have been followed by improved performance. The domestic WAT Funds and International Select typically achieve their performance with less risk than their competitors; relative risks are greater for International Small Cap. 2. Management Fees relative to Peers. The management fee rankings of the Funds are generally well below the respective medians and, hence, less favorable to shareholders than their peer group funds. 3. Administrative Fees. The WAT Funds pay a bundled fee that combines advisory fees and administrative expense, so ranking these fees separately was not possible. 4. Management Fees relative to Other Accounts. CWAM's focus is its mutual funds. It does not actively seek to manage separate or institutional accounts. The few institutional accounts it does manage vary in rate structures. Some pay advisory fees commensurate with or higher than the WAT Funds. In a few instances, however, sub-advised accounts pay lower management fees than do the WAT Funds. 5. Costs to CWAM and its Affiliates. CWAM's costs do not appear excessive, and, in my view, it uses appropriate methodologies to allocate overhead costs. CWAM's affiliates do not appear to profit indirectly from CWAM's management agreement with the WAT Funds. 6. Profit Margins. CWAM's firm-wide profit margins are at the upper end of the industry, though these comparisons are hampered by limited industry data. High profit margins are not unexpected for firms that manage large, successful funds and have provided outstanding investment performance for investors. Profit margins for the WAT Funds are lower than the margins for other accounts managed by CWAM because of payments made to intermediaries that offer the WAT Funds through variable annuity products. CMAI, the Funds' administrator, currently experiences losses rather than profits, in connection with its activities relating to the WAT Funds. 7. Economies of Scale. Economies of scale do exist at CWAM and will expand, if the assets of the WAT Funds get larger. They are, however, only partially reflected in the management fee schedule for two of the four WAT Funds. If the Funds' assets continue to grow, under the Funds' current fee schedules, shareholders might not benefit in a manner generally commensurate with CWAM's increased profits 8. Nature and quality of services. This category includes a variety of considerations that are difficult to quantify, yet can have a significant bearing on the performance of the WAT Funds. Several areas merit comment. a. Continuity of Management. It is critical that capable and experienced portfolio managers remain committed to the Funds and are able to hire and retain analysts to assist them. CWAM must have in place appropriate incentive plans that align its management's interests with those of investors. Further, CWAM must maintain the independence of its investment process. It should also be supported by effective information technology. b. Compliance. CWAM has an effective compliance program and a variety of related services that are valuable to shareholders, such as, systems to ensure best execution of portfolio transactions and the daily review of security prices to ensure accuracy of the WAT Funds' NAV. c. Administration Services. The WAT Funds benefit from a variety of administrative services that are performed by CWAM and CMAI, including preparation of registration statements, calculation of Fund NAV's, accounting services, shareholder services, and other functions In my opinion, these conclusions, taken together, generally support the reasonableness of the proposed management agreement. In reaching this conclusion, I weighed heavily the outstanding performance of the WAT Funds relative to their peers. Performance is an investor's first concern. The expense incurred by shareholders to enjoy this performance is, however, high relative to competing funds, though expenses for the WAT Funds are (with one exception) comparable to the parallel Acorn Funds. Nonetheless, a more complete breakpoint schedule could address this issue as well as share with investors more fully the benefits of economies of scale. 22 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- VII. Recommendations The Trustees should consider the following proposals to address the issues identified in this Report. Some of these recommendations require the collection and evaluation of more data. This work cannot be accomplished effectively before the expiration of the existing advisory contract on July 31, 2005. Therefore, I recommend that the Trustees consider extending the existing contract pending consideration of these recommendations. These recommendations do not purport to offer the only avenues to address the opinions and conclusions I have expressed in this Report. Economies of scale, for example, can be addressed in a variety of ways in a management contract. Sound business judgment will guide how any particular area is addressed with due consideration given to all the factors that must be weighed in reaching a management agreement that best serves the WAT Fund shareholders. I believe the Trustees should consider the following: 1. Restructure the management fee schedule beyond the current breakpoints to reflect more fully economies of scale. The Trustees might consider several ways to accomplish this objective, including instituting a two-tier fee structure that incorporates a complex- or CWAM-wide fee (including assets held in separate accounts) and a fund specific fee, with each containing breakpoints to reflect their separate economies of scale. Another approach is to consider uniform breakpoints for all WAT Funds, including breakpoints above and below current asset levels. 2. Conduct further study to ensure that the costs paid to insurance company intermediaries are transparent. The Trustees could consider forming an ad hoc committee to gather and evaluate data regarding CWAM's payments to intermediaries and the services provided by those intermediaries. Such a committee might also seek the assistance of a consultant such as Ernst &Young. 3. Administrative Fees. Administrative and advisory fees could be unbundled to allow greater transparency and to permit distinct comparisons among peers. An administrative fee could also be formulated with a breakpoint schedule that shares the economies of scale available with shareholders. 4. Condition contract renewal on submission of an employment agreements or a management incentive plan designed to ensure the continued employment of senior management, under terms that align management's incentives with the interests of the WAT Funds' shareholders. Any incentive plan should be designed to permit CWAM to attract and retain the highest caliber investment professionals and support them with effective and reliable information technology systems. 5. Review with CWAM its anticipated capacity limitations and the degree to which increased staffing and effective incentives may address those issues. Robert P. Scales Chief Compliance Officer, Senior Vice President and General Counsel July 25, 2005 23 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT The Compliance/Contract Review Committee (the "Committee") of the board of trustees meets on a regular basis and holds special meetings as otherwise necessary or advisable to review the advisory agreement (the "Agreement") of Wanger Advisors Trust (the "Trust") and each series thereof (the "Funds") and determines whether to recommend that the full board approve the continuation of the Agreement for an additional term. The Committee is comprised of three or more trustees, each of whom is an independent trustee, and the Trust's Chief Compliance Officer ("CCO"), who is a non-voting member of the Committee. After the Committee has made its recommendation, the full board, including the independent trustees, determines whether to approve the continuation of the Agreement. In addition, the board, including the independent trustees, considers matters bearing on the Agreement at most of their other meetings throughout the year and meets at least quarterly with the portfolio managers employed by Columbia Wanger Asset Management, L.P. ("CWAM"), the Funds' investment adviser. The trustees receive all materials that they and CWAM believe to be reasonably necessary for them to evaluate the Agreement and determine whether to approve the continuation of the Agreement. Those materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and of the Funds' performance benchmarks, (ii) information on the Funds' advisory fees and other expenses, including information comparing the Funds' expenses to those of peer groups of funds and information about any applicable expense caps and fee "breakpoints," (iii) share sales and redemption data, (iv) information about the profitability to CWAM and its affiliates of their relationships with the Funds and potential "fall-out" or ancillary benefits that CWAM and its affiliates may receive as a result of their relationships with the Funds and (v) information obtained through CWAM's response to a questionnaire prepared at the request of the trustees by Bell, Boyd & Lloyd LLC, independent counsel to the Trust and to the independent trustees. The trustees may also consider other information such as (i) CWAM's financial results and financial condition, (ii) each Fund's investment objective and strategies and the size, education and experience of CWAM's investment staffs and their use of technology, external research and trading cost measurement tools, (iii) the allocation of the Funds' brokerage, if any, including allocations to brokers affiliated with CWAM, and the use of "soft" commission dollars to pay Fund expenses or to pay for research products and services, (iv) the resources devoted to, and the record of compliance with, the Funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (v) the response of CWAM and its affiliates to various legal and regulatory proceedings since 2003 and (vi) the economic outlook generally and for the mutual fund industry in particular. In addition, the trustees conferred with, and reviewed the Management Fee Evaluation prepared by, the Trust's Senior Officer, who was appointed by the trustees as contemplated by the Assurance of Discontinuance dated February 9, 2005 among affiliates of CWAM and the Office of the New York Attorney General. A summary of the Management Fee Evaluation is included in this report. Throughout the process, the trustees have the opportunity to ask questions of and request additional materials from CWAM. On July 25, 2005 the board of trustees most recently approved the continuation of the Agreement through October 31, 2005, and on September 28, 2005 the board approved an amended and restated Agreement (the "Amended Agreement") for an initial term ending on July 31, 2006. The board actions followed Committee meetings held in June, July and September 2005. The board determined in the first instance to continue the Agreement through October (rather than for a full year period) pending the resolution of the compensation and incentive plan for key CWAM employees, whose employment agreements were to terminate in December, 2005. Those matters were resolved prior to September 28, 2005. In considering whether to approve the continuation of the Agreement and to approve the Amended Agreement, the trustees, including the independent trustees, did not identify any single factor as determinative, and each weighed the various factors as he or she deemed appropriate. The trustees considered the following matters in connection with their continuation of the Agreement and, except as noted in connection with their approval of the Amended Agreement (collectively with the Agreement, the "Agreements"). Nature, quality and extent of services. The trustees reviewed the nature, quality and extent of CWAM's services to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge gained from the board's regular meetings with management. In addition, the trustees reviewed CWAM's resources and key personnel, especially those who provide investment management services to the Funds. The trustees considered the importance of the continuity of management. At the September 28, 2005 meeting, the trustees considered the fact that Columbia Management, Inc. ("CM") and CWAM had agreed on a new compensation and incentive plan for key CWAM employees. The trustees also considered other services provided to the Funds by CWAM, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, providing support services for the board and board committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various Fund policies and procedures and with applicable securities laws and regulations. The trustees concluded that the nature and extent of the services provided by CWAM to each Fund were appropriate and consistent with the terms of the Agreements, that the quality of those services had been consistent with or superior to quality norms in the industry and that the Funds were likely to benefit from the continued provision of those services. They also concluded that CWAM had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. Performance of the Funds. The trustees considered the short-term and longer-term performance of each Fund. They reviewed information comparing each Fund's performance with the performance of the Fund's benchmark and with the performance of comparable funds and peer groups identified by Lipper Inc. ("Lipper") and Morningstar Associates, LLC ("Morningstar"). They noted that the two domestic Funds, Wanger U.S. Smaller Companies and Wanger Select, have each outperformed their respective benchmarks and Lipper and Morningstar peers. The trustees considered that Lipper and Morningstar ranked Wanger U.S. Smaller Companies first in its peer group for the past five years and Wanger Select first in its peer group for the three and five-year periods. The trustees discussed the performance of the two international Funds, Wanger International Small Cap and Wanger International Select, noting that each Fund's performance had improved over the past two years. They considered that Morningstar ranked Wanger International Small Cap first in its peer group for the one-year period and Lipper ranked it first in its peer group for the three-year period. They also considered that Lipper ranked Wanger International Select first in its peer group for the one-year period and second in its peer group for the three and five-year periods. The trustees concluded that although past performance is not necessarily indicative of future results, the Funds' improving performance record and investment process enhancements were important factors in the trustees' evaluation of the quality of services provided by CWAM under the Agreement. Costs of Services and Profits Realized by CWAM. The trustees examined information on fees and expenses of each Fund in comparison to information for other comparable funds as provided by Lipper and Morningstar. They considered that both the contractual rates of advisory fees and the actual advisory fees for most of the Funds were higher than the median advisory fees of the respective peer groups. The trustees also considered that the expense ratios of each Fund were also higher than the median expense ratios of the respective peer groups. At the July 25, 2005 meeting, at the recommendation 24 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT of the Committee, the board approved a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above, effective August 1, 2005. The trustees reviewed information on the profitability of CWAM in serving as each Fund's investment adviser and of CWAM and its affiliates in all of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other business units. The trustees considered the methodology used by CWAM in determining compensation payable to portfolio managers and the very competitive environment for investment management talent. The trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and profitability of any manager is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the manager's capital structure and cost of capital. However, based on the information available and taking those factors into account, the trustees concluded that the profitability of CWAM regarding each Fund in relation to the services rendered was not unreasonable. The trustees also reviewed CWAM's advisory fees for its institutional separate accounts. Although in most instances its institutional separate account fees for various investment strategies were lower than the advisory fees charged to the Funds with corresponding strategies, the trustees noted that CWAM performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the trustees considered the financial condition of CWAM, which they found to be sound. The trustees concluded that the advisory fees (including the additional breakpoint for Wanger International Small Cap) and other compensation payable by the Funds to CWAM and its affiliates were reasonable in relation to the nature and quality of the services to be provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees CWAM charges to other clients. The trustees noted, however, that they would continue to evaluate the Funds' investment advisory fee rates. The trustees also concluded that the Funds' estimated overall expense ratios, taking into account quality of services provided by CWAM and the investment performance of the Funds, were also reasonable. Economies of Scale. The trustees noted that the advisory fee schedule for each of Wanger U.S. Smaller Companies and Wanger International Small Cap contains two breakpoints that reduce the fee rate on assets above specified levels. They also noted that they had agreed to establish a new breakpoint for Wanger International Small Cap. The trustees concluded that with the additional breakpoint for Wanger International Small Cap, the fee schedule for each Fund would represent a sharing of economies of scale at current asset levels. They agreed, however, to continue their periodic consideration of the Funds' fee structures and economies of scale. Other Benefits to CWAM. The trustees also considered benefits that accrue to CWAM and its affiliates from their relationship with the Funds. The trustees concluded that, other than the services to be provided by CWAM and its affiliates pursuant to the Agreement and the fees payable by the Funds therefor, the Funds and CWAM may potentially benefit from their relationship with each other in other ways. Recognizing that an affiliate of CWAM serves the Funds as transfer agent and receives compensation from the Funds for those services, the trustees determined that such compensation was not unreasonable. They noted that the Funds' transfer agent reported that it made a small profit on its work for the Funds. The trustees also considered CWAM's use of commissions to be paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting the Funds and/or other clients of CWAM. The trustees concluded that CWAM's use of "soft" commission dollars to obtain research products and services was consistent with regulatory requirements and is beneficial to the Funds. They concluded that, although CWAM derives or may derive additional benefits through the use of soft dollars from the Funds' portfolio transactions, the Funds also benefit from the receipt of research products and services to be acquired through commissions paid on the portfolio transactions of other clients of CWAM. New Terms of the Amended Agreement. As previously mentioned, the trustees negotiated a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above. That new breakpoint is reflected in the Amended Agreement. In addition, the Amended Agreement includes representations by CWAM that are substantially similar to those contained in a letter agreement between the Trust and CM that expired on October 31, 2005. The Amended Agreement provides that: (1) CWAM will endeavor to preserve the autonomy of the Trust; (2) CWAM remain a wholly owned subsidiary of CM (or any successor company) as a Chicago-based management firm; (3) CWAM will maintain the investment philosophy and research that the Chicago-based management deems appropriate, research activities separate and dedicated solely to CWAM and its own domestic and international trading activities; (4) CWAM will use its best efforts to maintain information systems that will provide timely and uninterrupted operating information and data consistent with all regulatory and compliance requirements; (5) CWAM's Chicago-based management will have the responsibility and considerable latitude to recruit and compensate (on a competitive basis) investment management personnel and to control travel budgets for analysts consistent with its operational and strategic plans while subject to the approval of CM; and (6) CWAM acknowledges the importance that the Board and its compliance/contract review committee place on full legal and regulatory compliance by CMG, CWAM, and all other Trust service providers and their personnel (collectively, "Providers") and agrees to (i) cooperate fully with the Board, the compliance/contract review committee and the CCO of the Trust with all inquiries by the Trust concerning such compliance by the Providers and (ii) communicate proactively with the Board, the compliance/contract review committee and the CCO of the Trust concerning material compliance matters and any instance of legal or regulatory non-compliance by the Providers of which CWAM is aware and that CWAM deems to be material. Such cooperation and communication by CWAM will be done after receipt of an inquiry or upon learning of any such legal or regulatory non-compliance. Lastly, the Amended Agreement provides that the principal investment management focus and responsibilities of CWAM's portfolio managers and analysts will be dedicated to the Trust and Columbia Acorn Trust. After full consideration of the above factors as well as other factors that were instructive in analyzing the Agreement, the trustees, including all of the independent trustees, concluded that the continuation of the Agreement was in the best interest of each Fund. On July 25, 2005, the trustees continued the Agreement, as revised to include an additional breakpoint for Wanger International Small Cap, through October 31, 2005, and on September 28, 2005, the trustees approved the Amended Agreement. 25 Wanger International Small Cap 2005 Annual Report - -------------------------------------------------------------------------------- SPECIAL NOTICE A special meeting of the shareholders was held on November 30, 2005 for the purpose of electing nine trustees.

THE DISCUSSION IN THE REPORT OF PORTFOLIO COMPANIES IS FOR ILLUSTRATION ONLY AND IS NOT A RECOMMENDATION OF INDIVIDUAL STOCKS. THE INFORMATION IS BELIEVED TO BE ACCURATE, BUT THE INFORMATION AND THE VIEWS OF THE PORTFOLIO MANAGERS MAY CHANGE AT ANY TIME WITHOUT NOTICE AND THE PORTFOLIO MANAGERS MAY ALTER A FUND'S PORTFOLIO HOLDINGS BASED ON THESE VIEWS AND THE FUND'S CIRCUMSTANCES AT THAT TIME. Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- UNDERSTANDING YOUR EXPENSES As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. ANALYZING YOUR FUND'S EXPENSES To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in the fund during the reporting period. The information in the following table is based on an initial investment of $1,000.00, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using actual operating expenses. The amount listed in the "hypothetical" column assumes that the return each year is 5% before expenses and then applies each Fund's actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the reporting period. See the "Compare with other funds" information for details on using the hypothetical data. ESTIMATING YOUR ACTUAL EXPENSES To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period. 1. Divide your ending account balance by $1,000.00. For example, if an account balance was $8,600.00 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your fund. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. July 1, 2005 - December 31, 2005 Account value at the Account value at the Expenses paid during Fund's annualized beginning of the period ($) end of the period ($) the period ($) expense ratio (%)* - --------------------------------------------------------------------------------------------------------------------------- - --------------------------------------------------------------------------------------------------------------------------- Actual Hypothetical Actual Hypothetical Actual Hypothetical - --------------------------------------------------------------------------------------------------------------------------- Wanger Select 1,000.00 1,000.00 1,114.08 1,020.21 5.28 5.04 0.99 - --------------------------------------------------------------------------------------------------------------------------- Expenses paid during the period are equal to the fund's annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the investment adviser not waived a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund. As a shareholder of the fund, you do not incur any transaction costs, such as sales charges, redemption or exchange fees. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. The hypothetical example provided is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds whose shareholders may incur transaction costs. *For the six months ended 12/31/05. COMPARE WITH OTHER FUNDS Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transactional costs, such as sales charges or redemption or exchange fees, that may be incurred by shareholders of other funds. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. 1 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- [Graphic: Squirrel] NO ORDINARY PORTFOLIO MANAGERS I began working with Ralph Wanger, founder of Columbia Wanger Asset Management, in 1978. Shortly thereafter he issued the third quarter shareholder report for one of our retail funds. In it he wrote: "...hedonism is in... Let us explore the possibility that we have been going through the oldest cycle of all--from Good to Bad." In order to prove that badness was more profitable than goodness, Ralph tested two portfolios for 36-month price changes. The virtuous portfolio included Angelica, up 45%, and Church's Fried Chicken, up 520%. The wicked portfolio included Playboy, up 600%, and DeBeers Mines, up 59%.1 The wicked portfolio won. Ralph's footnote to his essay read: "This study was done by the usual techniques of Financial Analysis: (A) The stocks chosen had nothing to do with the subject, and (B) The portfolios were readjusted until the answer affirmed the hypothesis." At that point it became very clear to me that Ralph Wanger was no ordinary portfolio manager! Ralph parlayed his legendary shareholder reports into his book, A Zebra in Lion Country.2 The book could have been titled, The Wit and Wisdom of Ralph Wanger. In it Ralph admits that his first quarterly newsletters were serious and stuffy. He said that he gave market and economic forecasts that quickly became outdated. Then he decided, "If most mutual fund communications are both boring and wrong, well then, I figured, I'd rather be lively and wrong." There's a lot of Wisdom in A Zebra in Lion Country. Examples include: "Look for stocks that have basic value but are out of fashion." Ralph also wrote, "The greatest investment profit comes when an ugly duckling becomes a swan." And, "If a company's earnings beat the Merrill Lynch analyst's forecast by 2 cents, that doesn't excite me. I need a long-term reason to own a stock." And Ralph meant long term. "...you can't make five or ten or twenty times your money if you don't hold on to your stocks. Most people are delighted when a stock doubles, and quickly sell to lock in their gain," he wrote in his book. Ralph's long-term thinking was driven home in a report essay he wrote in June 1992: "What really makes for successful investing is having a few enormous hits. In 22 years, I've really had three Super Stocks." Houston Oil & Minerals was one. Houston Oil cost $220,000 in 1973 and went to $5.3 million in 1977. Another was Cray Research, which cost $1.5 million in 1978 and was worth $20 million in 1985. International Game Technology, a maker of slot machines, cost $5 million in 1988 and was worth $80 million by June 1992.3 Ralph also had his share of disasters. He wrote in that 1992 report, "There is one stock we tried to sell for two years and never got a bid on any of it. A stock like that just slides from 4 to 3 to 2 to 1 and finally disappears..." Ralph said, "It's kind of like a doctor saying don't worry about it, it's just going to shrivel up and fall off." Atchison Casting, an owner of steel foundries, was a painful example of this. Ralph began purchasing the stock in 1994 and it ended up being nearly worthless when it was sold in 2003. The wisdom here is that small-cap investing can be a winner's game. Let your winners run. On any individual stock, one can possibly make several thousand percent, but the most that one can lose is 100%. Small-cap investors will have some big percentage losers, but damage to portfolios can be minor as long as investors don't keep throwing money at them and if they maintain a well-diversified portfolio. How did Ralph use his genius and wisdom to build a successful firm? A few years after I joined Ralph we had a heated discussion about a stock. The next day I asked him if I had crossed the line during our debate. He looked at me kind of puzzled and said, course not, if we always agreed, why would I need you?" Ralph always respected differing opinions and created a culture of intellectual freedom. In an investment world full of wishful thinking, Ralph also demanded intellectual honesty. The ability to ask tough questions, get sound answers, discover good businesses, detect strong managers and then value stocks appropriately, requires intellectual honesty. Then it's time to act. I remember an analyst saying that a stock trades by appointment and Ralph responding, "Then make an appointment and buy it!" The culture that Ralph fostered allowed Columbia Wanger Asset Management to grow and helped its shareholders to prosper. Leah Zell's contribution to Columbia Wanger Asset Management has also been huge and complementary to Ralph's. Leah seemed to have the ability to see around corners strategically and make quick, good decisions. When Leah joined our team in 1984, she began as a domestic analyst following mostly real estate and retail stocks. Leah then became our first foreign analyst. She successfully launched our first international retail mutual fund, Acorn International, realizing great investment results, and taking the Fund from zero to one billion dollars in assets under management in 14 months. Of course, she could not have done it without a team. Leah built the international area at Columbia Wanger Asset Management. International investing requires all the skills needed for domestic investing, and more. At Columbia Wanger, we like to hire international analysts who also have language skills and cultural 2 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- knowledge. In a number of cases, Leah successfully mentored new analysts who had these traits and fine financial skills but had a lot to learn about security analysis. We at Columbia Wanger Asset Management are happy that Ralph and Leah kept their offices with us and have been advisors over the last two years. We've gotten good advice, but Ralph and Leah made it clear that the decisions were ours. In our semiannual report we published Ralph's last column, which appeared in this section. Ralph once said of writing his essays, "It is fun for me and only mildly irritating to our shareholders." We are grateful to have had Ralph's and Leah's presence and wisdom for all these years. On September 30, 2005, they retired from their advisory roles with the firm. DOMESTIC SMALL-CAP CYCLE Small caps have outperformed large caps for over six years now; by our reckoning, small caps bottomed vs. large caps in March 1999. The small-cap Russell 2500 Index returned 110% from that date through December 31, 2005, far outpacing the S&P 500, which returned 8%. In the past, small-cap stocks had long cycles of out- and under-performance vs. large caps. There is no science and there is no magic in predicting the exact top of a small-cap cycle. Perhaps small caps will continue to outperform--some believe small caps will outperform as long as rapid earnings growth continues and some others believe outperformance will persist until the overall market turns. Numerous economists are predicting higher inflation rates, and small caps did relatively well during the inflationary periods of the 1970s. However, when looking at price-to-earnings ratios, small caps appear expensive vs. large caps. Using another measure, price-to-book value, small caps appear somewhat more reasonably priced. While we don't think domestic small caps are back to their all-time relative high valuations, we do think small-cap domestic stocks on average are no longer cheap. We do not predict market cycles. We stick to what we believe we do best: buying reasonably priced small- and mid-cap stocks and when they enter periods of higher valuations, we try to become more selective. Over time this consistently applied approach has weathered the Funds through a variety of market cycles. While we certainly can't predict what the future holds, the best defense against unknown market factors is diversification across assets, which is a prudent and time-tested investment strategy. COLUMBIA WAM NEWS We are pleased to announce that Satoshi Matsunaga has joined our international analyst team covering Japan. He came on board in September. Before joining Columbia Wanger Asset Management, he was with Compass Advisers in New York. Satoshi holds an MBA from the University of Michigan and a bachelor's in economics from Keio University in Tokyo, Japan. As a Japanese national, Satoshi brings first-hand knowledge of the country and culture. After the close of the period, we hired a new energy analyst. In January, William Doyle came on board. Bill was most recently a manager of PPM America's credit analysis team where part of his responsibilities included following the high yield energy sector. Bill's degrees include an MBA from Loyola University in Chicago and bachelor's degrees in finance and history from Illinois State University. We are pleased to welcome Satoshi and Bill to the team.

These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Wanger Advisor Fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Fund. References to specific company securities should not be construed as a recommendation or investment advice. Past performance is no guarantee of future results. Mid- and 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. 3 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- [Graphic: Squirrel] PERFORMANCE REVIEW WANGER SELECT Photo of: BEN ANDREWS BEN ANDREWS Portfolio Manager Performance data quoted represents past performance and current performance may be lower or higher. Past performance is no guarantee of future results. The investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than the original cost. For monthly performance updates call 1-888-4-WANGER. Wanger Select gained 10.49% in 2005, trailing the S&P MidCap 400, up 12.56%. The large-cap S&P 500 was up just 4.91% for the year. Performance was driven by a number of stocks. The Fund's top four dollar gainers were Abercrombie & Fitch, Tellabs, American Tower and Coventry Health Care, which added nearly 7% to the Fund's annual return. The Fund had only one big loser this year, security software developer McAfee, which was sold in the second quarter. The stock cost the Fund 2.2% for the year. Wanger Select purchased its first raw material stocks (beyond energy) in the second half of 2005. Throughout Columbia Wanger's history, we have not focused on commodities because we felt the majority of commodity companies could not differentiate themselves enough for us to find a superior business model. To make money in commodities one has to rely on price appreciation and, when supply and demand are in line, prices are often flat to down. A year-and-a-half ago, Columbia Wanger hired its first raw materials analyst, Fritz Kaegi. We recognized that a number of commodity industries had not added new supply capacity in more than 10 years. As global demand has increased, many commodity companies have started to deplete their excess capacity, leaving them with tight supply and putting upward pressure on prices. September and October of 2005 were rough months for these stocks and the sell-off that occurred gave us our entry point. Wanger Select invested in Potash of Saskatchewan and UrAsia Energy, which focus on the crop nutrient market and the uranium market, respectively. We believe we are just a few years into what could be a long-term cycle of outperformance in commodities. However, the sector can be volatile. Potash's stock, for example, fell 35% from August through October and this drastic decline was not triggered by any major event. We do not anticipate adding a large commodities weighting to the Fund but it does seem to be the right time to broaden the Fund's portfolio to include some exposure to this sector. In the quarter we purchased the two new stocks mentioned above and sold one, CDW. CDW, a technology reseller, was sold because we became increasingly uncertain about the company's ability to meet our growth projections over the next year. For 2006 the Fund's focus is simple: To continue to make money for the Fund's shareholders and to beat the mid-cap benchmark. Wanger Select is a non-diversified fund. The performance of each of its holdings will have a greater impact on the Fund's total return, and may make the Fund's returns more volatile than a more diversified fund. Mid-cap stocks tend to be more volatile and may be less liquid than the stocks of larger companies. As of 12/31/05 the Fund's positions in the stocks mentioned were: Abercrombie & Fitch, 5.0%; Tellabs, 5.8%; American Tower, 3.7%; Coventry Health Care, 2.8%; McAfee, 0.0%; Potash of Saskatchewan, 0.9%; UrAsia Energy, 3.5%; CDW, 0.0%. 4 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- GROWTH OF A $10,000 INVESTMENT IN WANGER SELECT TOTAL RETURN FOR EACH PERIOD, FEBRUARY 1, 1999 (INCEPTION DATE) THROUGH DECEMBER 31, 2005 AVERAGE ANNUAL TOTAL RETURN ---------------------------------------------- 1 year 5 years Life of fund 10.49% 11.67% 14.51% WANGER SELECT: $25,527 S&P MidCap 400: $21,192 Line Chart: WANGER SELECT S&P MidCap 400 2/28/99 9750 9476.42 3/31/99 10530 9741.15 4/30/99 12150 10509.5 5/31/99 12220 10555.1 6/30/99 12530 11120.2 7/31/99 12510 10883.9 8/31/99 11420 10510.9 9/30/99 11410 10186.3 10/31/99 12250 10705.4 11/30/99 12510 11267.2 12/31/99 13430 11936.9 1/31/00 13090 11600.7 2/29/00 13100 12412.6 3/31/00 13696.7 13451.5 4/30/00 13049.5 12981.8 5/31/00 12694.5 12819.8 6/30/00 13822 13008.1 7/31/00 13404.4 13213.6 8/31/00 14782.4 14688.9 9/30/00 15064.3 14588.3 10/31/00 15126.9 14093.6 11/30/00 13748.9 13029.8 12/31/00 14698.9 14026.6 1/31/01 15231.3 14339 2/28/01 14312.7 13520.7 3/31/01 13790.7 12515.5 4/30/01 14761.6 13896.1 5/31/01 15555 14219.7 6/30/01 15220.9 14162.3 7/31/01 15053.9 13951.3 8/31/01 14427.5 13495 9/30/01 13592.3 11816.4 10/31/01 13895.1 12339.1 11/30/01 15387.9 13257 12/31/01 16035.2 13941.9 1/31/02 15763.8 13869.5 2/28/02 15398.4 13886.5 3/31/02 15920.3 14879.2 4/30/02 15043.4 14809.6 5/31/02 15481.9 14559.9 6/30/02 15210.5 13494.2 7/31/02 14302.2 12187.1 8/31/02 14698.9 12248.4 9/30/02 13978.6 11261.6 10/31/02 14813.7 11749.6 11/30/02 15450.6 12429.3 12/31/02 14813.7 11918.6 1/31/03 14709.4 11570.3 2/28/03 14751.1 11294.7 3/31/03 15022.5 11389.9 4/30/03 15889 12216.9 5/31/03 16786.8 13229.3 6/30/03 17277.5 13397.9 7/31/03 17997.8 13873.3 8/31/03 18718.1 14502.6 9/30/03 18311 14280.6 10/31/03 19083.5 15360.4 11/30/03 18979.1 15895.6 12/31/03 19365.4 16163.8 1/31/04 19908.3 16514.1 2/29/04 20472 16910.6 3/31/04 20481.1 16982.4 4/30/04 19906.4 16425 5/31/04 20219.9 16765.7 6/30/04 20961.8 17147.3 7/31/04 20000.5 16347.2 8/31/04 19749.7 16304.4 9/30/04 20167.6 16787.2 10/31/04 21035 17055.8 11/30/04 22362.1 18071.5 12/31/04 23104 18828.2 1/31/05 22278.5 18347.6 2/29/05 21965 18963.1 3/31/05 21843.5 18753.2 4/30/05 20987.3 18024.4 5/31/05 21933.6 19109.8 6/30/05 22913.7 19552.9 7/31/05 23938.9 20579.9 8/31/05 23465.7 20350.5 9/30/05 23961.4 20507 10/31/05 23837.5 20066.3 11/30/05 25234.4 21046.8 12/31/05 25527.3 21192.3 This graph compares the results of $10,000 invested in Wanger Select on February 1, 1999 (the date the Fund began operations) through December 31, 2005, to the S&P MidCap 400 Index, with dividends and capital gains reinvested. DUE TO ONGOING MARKET VOLATILITY, PERFORMANCE IS SUBJECT TO SUBSTANTIAL SHORT-TERM FLUCTUATIONS. Part of the performance shown is due to the Fund's purchase of securities in IPOs. The impact of IPO purchases declines as a Fund grows large. Wanger Select is a non-diversified fund that invests primarily in the stocks of medium- to larger-size U.S. companies. Each stock may represent a significant part of its overall portfolio. The performance of each of these larger holdings will have a greater impact on Wanger Select's total return and may make the Fund's returns more volatile than a more diversified fund. Mid-cap stocks are more volatile and may be less liquid than large-cap stocks. 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. PERFORMANCE SHOWN HERE IS PAST PERFORMANCE, WHICH CANNOT GUARANTEE FUTURE RESULTS. CURRENT PERFORMANCE MAY BE HIGHER OR LOWER. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PERFORMANCE CHANGES OVER TIME. CURRENT RETURNS FOR THE FUND MAY BE DIFFERENT THAN THAT SHOWN.

See accompanying notes to financial statements. 11 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 1. NATURE OF OPERATIONS Wanger Select (known prior to May 1, 2004 as Wanger Twenty), (the "Fund"), is a series of Wanger Advisors Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of the Fund is to seek long-term growth of capital. The Fund is available only for allocation to certain life insurance company separate accounts established for the purpose of funding qualified and non-qualified variable annuity contracts, and variable life insurance policies and may also be offered directly to certain types of pension plans and retirement arrangements. 2. SIGNIFICANT ACCOUNTING POLICIES SECURITY VALUATION Securities of the Fund are valued at market value or, if a market quotation for a security is not readily available or is deemed not to be reliable because of events or circumstances that have occurred between the market quotation and the time as of which the security is to be valued, the security is valued at a fair value determined in accordance with procedures established by the Board of Trustees. 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 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. Short-term debt obligations 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 readily available and any other assets are valued as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. The Trust has retained an independent statistical fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security. REPURCHASE AGREEMENTS The Fund may engage in repurchase agreement transactions. The Fund, through its custodians, 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 repurchase price including interest. 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 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 Fund. Interest income is recorded on an accrual basis and includes amortization of discounts on short-term debt obligations and on long-term debt obligations when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. 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 ("the Exchange") on each day the Exchange is open for trading by dividing the total value of the Fund's investments and other assets, less liabilities, by the number of Fund shares outstanding. INDEMNIFICATION In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Trust's organizational documents, the Trustees and Officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these warranties and indemnities to be minimal. CUSTODY FEES/CREDITS Custody fees are reduced based on the Fund's cash balances maintained with the custodian. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such agreement. The amount is disclosed as a reduction of total expenses in the Statement of Operations. FEDERAL INCOME TAXES The Fund has complied with the provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distributes 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 The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund's capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2005, permanent book and tax basis differences resulting primarily from differing treatments for foreign currency transactions, were identified and reclassified among the components of the Fund's net assets as follows: ACCUMULATED ACCUMULATED PAID IN NET INVESTMENT LOSS NET REALIZED GAIN CAPITAL - ---------------------------------------------------------------- $(10,318) $10,318 $-- Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. 12 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS The tax character of distributions paid during the year ended December 31, 2005 was as follows: DECEMBER 31, 2005 DECEMBER 31, 2004 ----------------- ----------------- Distributions paid from: Ordinary Income* $ 557,324 $ -- Long-Term Capital Gain 5,229,252 56,308 * For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of December 31, 2005, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED NET UNREALIZED ORDINARY LONG-TERM APPRECIATION INCOME CAPITAL GAINS (DEPRECIATION)* --------------- --------------- --------------- $962,547 $3,364,986 $22,926,876 * The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to passive foreign investment company ("PFIC") adjustments. 4. TRANSACTIONS WITH AFFILIATES Columbia Wanger Asset Management, L.P., ("Columbia WAM") a wholly owned subsidiary of Columbia Management, Inc., (CM), which in turn is an indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), furnishes continuing investment supervision to each Fund and is responsible for the overall management of each Fund's business affairs. Effective March 8, 2005, under the Fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 0.85% of average daily net assets. Prior to March 8, 2005, under the Fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 0.95% of average daily net assets. In accordance with the terms of the Assurance of Discontinuance with the New York Attorney General, Columbia WAM waived a portion of the fees payable under the Fund's investment management agreement so that those fees are retained at 0.85% of average daily net assets. The fee waiver was effective from January 1, 2005 through March 8, 2005, but applied as if it had gone into effect on December 1, 2004. Fees waived by Columbia WAM amounted to $14,597 for the year ended December 31, 2005. The investment advisory agreement also provides that through April 30, 2006 Columbia WAM will reimburse the Fund to the extent that ordinary operating expenses (computed based on net custodian fees) exceed an annual percentage of 1.35% of average daily net assets. There was no reimbursement for the year ended December 31, 2005. 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. For the year ended December 31, 2005, the Fund paid $9,604 to trustees not affiliated with Columbia WAM. The Board of Trustees appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. These expenses are disclosed separately as "Compliance fees" on the Statement of Operations. Columbia Management Distributors, Inc. (formerly Columbia Funds Distributor, Inc.), a wholly owned subsidiary of BOA, serves as the principal underwriter of the Trust and receives no compensation for its services. Columbia Management Services, Inc. (formerly Columbia Funds Services, Inc.) (the "Transfer Agent"), a wholly-owned subsidiary of BOA, provides shareholder services to the Fund and has subcontracted with Boston Financial Data Services ("BFDS") to serve as subtransfer agent. For such services, the Transfer Agent receives a fee, paid monthly, at the annual rate of $21.00 per open account. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. During the year ended December 31, 2005, the Fund engaged in purchase and sales transactions with funds that have a common investment advisor (or affiliated investment advisors), common Directors/Trustees, and/or common Officers. These purchase and sale transactions complied with the provisions of Rule 17a-7 under the Investment Company Act of 1940 and were $0 and $72,621, respectively. 5. BORROWING ARRANGEMENTS The Trust participates in a $150,000,000 credit facility, which was entered into to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at rate per annual equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. No amounts were borrowed under this facility for the year ended December 31, 2005. 6. FUND SHARE TRANSACTIONS Proceeds and payments on Fund shares as shown in the statement of changes in net assets are in respect of the following numbers of shares: Year ended Year ended December 31, 2005 December 31, 2004 - -------------------------------------------------------------------------------- Shares sold 1,226,585 1,465,607 Shares-issued-in-reinvestment of dividend distributions 294,782 2,911 Less shares redeemed 720,738 547,475 Net increase in shares outstanding 800,629 921,043 7. INVESTMENT TRANSACTIONS The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2005 were $36,552,742 and $21,169,806. 8. OTHER During the year ended December 31, 2005 and as a result of an error, the Fund purchased shares of AnswerThink that were subsequently sold at a loss of $14,286. The Fund was reimbursed by Columbia WAM for the full amount of the loss. 9. LEGAL PROCEEDINGS Columbia WAM, Columbia Acorn Trust, another mutual fund family advised by Columbia WAM, and the trustees of Colombia Acorn Trust, are named as defendants in class and derivative complaints which have been consolidated in a Multi-District Action in the federal district court for the District of Maryland. These lawsuits contend that defendants permitted certain investors to market time their trades in certain Columbia Acorn Funds. The Multi-District Action is ongoing. However, all claims against Columbia Acorn Trust, and the independent trustees of Columbia Acorn Trust have been dismissed. Columbia WAM, the Columbia Acorn Funds and the trustees of Columbia Acorn Trust are defendants in a consolidated lawsuit filed in the federal district court of Massachusetts alleging that Columbia WAM used Fund assets to make undisclosed payments to brokers as an incentive for the brokers to market the Columbia Acorn Funds over the other mutual funds to investors. The complaint alleges Columbia WAM and the Trustees of the Trust breached certain common laws duties and federal laws. All claims against all 13 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS defendants in this lawsuit have been dismissed. However the plaintiffs have filed a notice of appeal with the First Circuit Court of Appeals. The Columbia Acorn Trust and Columbia WAM are also defendants in a class action lawsuit that alleges, in summary, that the Columbia Acorn Trust and Columbia WAM exposed shareholders of Columbia Acorn International to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of that Fund's securities had occurred after foreign markets had closed but before the calculation of the Funds' net asset value ("NAV"); (b) failing to implement the Fund's portfolio valuation and share pricing policies and procedures; and (c) failing to know and implement applicable rules and regulations concerning the calculation of NAV (the "Fair Valuation Lawsuit"). The Seventh Circuit ruled that the plaintiffs' state law claims were preempted under federal law resulting in the dismissal of plaintiffs' complaint. However, plaintiffs are in the process of appealing that decision before the United States Supreme Court. On March 21, 2005, a class action complaint was filed against the Columbia Acorn Trust and Columbia WAM seeking to rescind the Contingent Deferred Sales Charges assessed upon redemption of Class B shares of Columbia Acorn Funds due to the alleged market timing of the Columbia Acorn Funds. In addition to the rescission of sales charges, plaintiffs seek recovery of actual damages, attorneys' fees and costs. The case has been transferred to the Multi-District Action in the federal district court of Maryland. The Columbia Acorn Trust and Columbia WAM intend to defend these suits vigorously. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Funds. In connection with the events described in detail above, various parties have filed suit against certain funds, their Boards and/or BOA (and affiliated entities). These suits are ongoing. However, based on currently available information, the Columbia Acorn Trust believes that the likelihood that these lawsuits will have a material adverse impact on any fund is remote, and Columbia WAM believes that the lawsuits are not likely to materially affect its ability to provide investment management services to the Funds. For the year ended December 31, 2005, CM has assumed $15,593 in consulting services and legal fees incurred by the Fund in connection with these matters. 14 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of Wanger Select Fund: In our opinion, the accompanying statement of assets and liabilities, including the statement of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Wanger Select Fund (a series of the Wanger Advisors Trust, hereinafter referred to as the "Fund") at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at December 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights of the Fund for the periods ended December 31, 2003 and prior were audited by other independent auditors whose report dated February 6, 2004 expressed an unqualified opinion on those financial statements. PricewaterhouseCoopers LLP Chicago, Illinois February 14, 2006 15 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- UNAUDITED INFORMATION FEDERAL INCOME TAX INFORMATION For the fiscal year ended December 31, 2005, the Fund designated long-term capital gains of $3,370,898. 16 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- [EXCERPTS FROM:] Wanger Advisors Trust Management Fee Evaluation of the Senior Officer Prepared Pursuant to the New York Attorney General's Assurance of Discontinuance July 2005 17 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- Introduction The New York Attorney General's Assurance of Discontinuance ("Order") entered into by Columbia Management Advisors, Inc. ("CMAI") and Columbia Funds Distributor, Inc., ("CFDI" and collectively with "CMAI," "CMG") in February 2005, allows CMAI to manage or advise a mutual fund, including the Wanger Advisors Trust's family of funds (the "WAT Funds" or "WAT" or "Trust"), only if the trustees of the WAT Funds appoint a "Senior Officer" to perform specified duties and responsibilities. One of these responsibilities includes "managing the process by which proposed management fees (including but not limited to, advisory fees) to be charged the WAT Fund[s] are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." The Order also provides that the Board of Trustees of the WAT Funds ("Board") must determine the reasonableness of proposed "management fees" by using either an annual competitive bidding process supervised by the Senior Officer or Independent Fee Consultant, or by obtaining "an annual independent written evaluation prepared by or under the direction of the Senior Officer or the Independent Fee Consultant." "Management fees" are only part of the costs and expenses paid by mutual fund shareholders. The expenses can vary depending upon the class of shares held but usually include: (1) investment management or advisory fees to compensate analysts and portfolio managers for stock research and portfolio management, as well as the cost of operating a trading desk; (2) administrative expenses incurred to prepare registration statements and tax returns, calculate the Funds' net asset values, maintain effective compliance procedures and perform recordkeeping services; (3) transfer agency costs for establishing accounts, accepting and disbursing funds, as well as overseeing trading in Fund shares; (4) custodial expenses incurred to hold the securities purchased by the Funds; and (5) distribution expenses, including commissions paid to brokers that sell the Fund shares to investors. Columbia Wanger Asset Management, L.P. ("CWAM"), the adviser to the WAT Funds, has proposed that the Trust enter into an agreement that "bundles" the first two categories listed above: advisory and administrative services. The fees paid under this agreement are referred to as "management fees." Other fund expenses are governed by separate agreements, in particular agreements with two CWAM affiliates: CFDI, the broker-dealer that underwrites and distributes the WAT Funds' shares, and Columbia Funds Services, Inc. ("CFSI"), the Funds' transfer agent. In conformity with the terms of the Order, this evaluation, therefore, addresses only the advisory and administrative contract between CWAM and the Trust, and does not extend to the other agreements. According to the Order, the Senior Officer's evaluation must consider at least the following: (1) Management fees (including components thereof) charged to institutional and other clients of CWAM for like services; (2) Management fees (including any components thereof) charged by other mutual fund companies for like services; (3) Costs to CWAM and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; (4) Profit margins of CWAM and its affiliates from supplying such services; (5) Possible economies of scale as the WAT Funds grow larger; and (6) The nature and quality of CWAM's services, including the performance of each WAT Fund. On November 17, 2004, the Board appointed me, Robert Scales, Senior Officer under the Order. The Board also determined not to pursue a competitive bidding process and instead, charged me with the responsibility of evaluating the WAT Funds' proposed advisory and administrative fee contract with CWAM in conformity with the requirements of the Order. This Report is an annual evaluation required under the Order. In discharging their responsibilities, the independent Trustees have also consulted independent, outside counsel. * * * This evaluation was performed in cooperation and regular communication with the Compliance/Contract Renewal Committee of the Board. Process and Independence The objectives of the Order are to ensure the independent evaluation of the advisory fees paid by the WAT Funds as well as to ensure that all relevant factors are considered. In my view, the contract renewal process has been conducted at arms-length and with independence in gathering, considering and evaluating relevant data. For example, the selection of fund peer groups is critical in assessing a fund's relative performance and cost. I have required Lipper and Morningstar, Inc. to prepare their reports without input or commentary from CWAM; the engagement letters with them reflect this requirement. As a result, the peer groups reflected in the Morningstar, Inc. and Lipper reports were determined independently. After submission of the reports, I asked CWAM to comment on them to avoid errors and to establish a clear record of CWAM's views on which funds, in its judgment, constitute an appropriate peer group. Similarly, I discussed CWAM's profitability analysis with its management but also sought the independent views of Ernst &Young on the reasonableness of CWAM's cost allocation methodology and on the adequacy of the financial data it provided. The evaluation of CWAM's profitability was performed in the context of the limited industry data available. My evaluation of the advisory contract was shaped by my experience as WAT's Chief Compliance Officer ("CCO"). As CCO, I report solely to the Board and have no reporting obligation to or employment relationship with CMG or its affiliates, except for administrative purposes. This too contributes to the independence of this evaluation. I have made several comments on compliance matters in evaluating the quality of service provided by CWAM and CMG. 18 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- Finally, this Report, its supporting materials and the data contained in other materials submitted to the Compliance/Contract Renewal Committee of the Board, in my view, provide a thorough factual basis upon which the Board, in consultation with independent counsel as it deems appropriate, may conduct management fee negotiations that are in the best interests of the WAT Funds' shareholders. * * * VI. Conclusions My review of the data and other material above leads to the following conclusions with respect to the factors identified in the Order. 1. Performance. The WAT Funds generally have achieved outstanding performance and rank very favorably against their peers. The international funds have good recent performance records, but weaker long-term performance relative to the domestic WAT Funds. Recent management changes have been followed by improved performance. The domestic WAT Funds and International Select typically achieve their performance with less risk than their competitors; relative risks are greater for International Small Cap. 2. Management Fees relative to Peers. The management fee rankings of the Funds are generally well below the respective medians and, hence, less favorable to shareholders than their peer group funds. 3. Administrative Fees. The WAT Funds pay a bundled fee that combines advisory fees and administrative expense, so ranking these fees separately was not possible. 4. Management Fees relative to Other Accounts. CWAM's focus is its mutual funds. It does not actively seek to manage separate or institutional accounts. The few institutional accounts it does manage vary in rate structures. Some pay advisory fees commensurate with or higher than the WAT Funds. In a few instances, however, sub-advised accounts pay lower management fees than do the WAT Funds. 5. Costs to CWAM and its Affiliates. CWAM's costs do not appear excessive, and, in my view, it uses appropriate methodologies to allocate overhead costs. CWAM's affiliates do not appear to profit indirectly from CWAM's management agreement with the WAT Funds. 6. Profit Margins. CWAM's firm-wide profit margins are at the upper end of the industry, though these comparisons are hampered by limited industry data. High profit margins are not unexpected for firms that manage large, successful funds and have provided outstanding investment performance for investors. Profit margins for the WAT Funds are lower than the margins for other accounts managed by CWAM because of payments made to intermediaries that offer the WAT Funds through variable annuity products. CMAI, the Funds' administrator, currently experiences losses rather than profits, in connection with its activities relating to the WAT Funds. 7. Economies of Scale. Economies of scale do exist at CWAM and will expand, if the assets of the WAT Funds get larger. They are, however, only partially reflected in the management fee schedule for two of the four WAT Funds. If the Funds' assets continue to grow, under the Funds' current fee schedules, shareholders might not benefit in a manner generally commensurate with CWAM's increased profits 8. Nature and quality of services. This category includes a variety of considerations that are difficult to quantify, yet can have a significant bearing on the performance of the WAT Funds. Several areas merit comment. a. Continuity of Management. It is critical that capable and experienced portfolio managers remain committed to the Funds and are able to hire and retain analysts to assist them. CWAM must have in place appropriate incentive plans that align its management's interests with those of investors. Further, CWAM must maintain the independence of its investment process. It should also be supported by effective information technology. b. Compliance. CWAM has an effective compliance program and a variety of related services that are valuable to shareholders, such as, systems to ensure best execution of portfolio transactions and the daily review of security prices to ensure accuracy of the WAT Funds' NAV. c. Administration Services. The WAT Funds benefit from a variety of administrative services that are performed by CWAM and CMAI, including preparation of registration statements, calculation of Fund NAV's, accounting services, shareholder services, and other functions In my opinion, these conclusions, taken together, generally support the reasonableness of the proposed management agreement. In reaching this conclusion, I weighed heavily the outstanding performance of the WAT Funds relative to their peers. Performance is an investor's first concern. The expense incurred by shareholders to enjoy this performance is, however, high relative to competing funds, though expenses for the WAT Funds are (with one exception) comparable to the parallel Acorn Funds. Nonetheless, a more complete breakpoint schedule could address this issue as well as share with investors more fully the benefits of economies of scale. 19 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- VII. Recommendations The Trustees should consider the following proposals to address the issues identified in this Report. Some of these recommendations require the collection and evaluation of more data. This work cannot be accomplished effectively before the expiration of the existing advisory contract on July 31, 2005. Therefore, I recommend that the Trustees consider extending the existing contract pending consideration of these recommendations. These recommendations do not purport to offer the only avenues to address the opinions and conclusions I have expressed in this Report. Economies of scale, for example, can be addressed in a variety of ways in a management contract. Sound business judgment will guide how any particular area is addressed with due consideration given to all the factors that must be weighed in reaching a management agreement that best serves the WAT Fund shareholders. I believe the Trustees should consider the following: 1. Restructure the management fee schedule beyond the current breakpoints to reflect more fully economies of scale. The Trustees might consider several ways to accomplish this objective, including instituting a two-tier fee structure that incorporates a complex- or CWAM-wide fee (including assets held in separate accounts) and a fund specific fee, with each containing breakpoints to reflect their separate economies of scale. Another approach is to consider uniform breakpoints for all WAT Funds, including breakpoints above and below current asset levels. 2. Conduct further study to ensure that the costs paid to insurance company intermediaries are transparent. The Trustees could consider forming an ad hoc committee to gather and evaluate data regarding CWAM's payments to intermediaries and the services provided by those intermediaries. Such a committee might also seek the assistance of a consultant such as Ernst & Young. 3. Administrative Fees. Administrative and advisory fees could be unbundled to allow greater transparency and to permit distinct comparisons among peers. An administrative fee could also be formulated with a breakpoint schedule that shares the economies of scale available with shareholders. 4. Condition contract renewal on submission of an employment agreements or a management incentive plan designed to ensure the continued employment of senior management, under terms that align management's incentives with the interests of the WAT Funds' shareholders. Any incentive plan should be designed to permit CWAM to attract and retain the highest caliber investment professionals and support them with effective and reliable information technology systems. 5. Review with CWAM its anticipated capacity limitations and the degree to which increased staffing and effective incentives may address those issues. Robert P. Scales Chief Compliance Officer, Senior Vice President and General Counsel July 25, 2005 20 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT The Compliance/Contract Review Committee (the "Committee") of the board of trustees meets on a regular basis and holds special meetings as otherwise necessary or advisable to review the advisory agreement (the "Agreement") of Wanger Advisors Trust (the "Trust") and each series thereof (the "Funds") and determines whether to recommend that the full board approve the continuation of the Agreement for an additional term. The Committee is comprised of three or more trustees, each of whom is an independent trustee, and the Trust's Chief Compliance Officer ("CCO"), who is a non-voting member of the Committee. After the Committee has made its recommendation, the full board, including the independent trustees, determines whether to approve the continuation of the Agreement. In addition, the board, including the independent trustees, considers matters bearing on the Agreement at most of their other meetings throughout the year and meets at least quarterly with the portfolio managers employed by Columbia Wanger Asset Management, L.P. ("CWAM"), the Funds' investment adviser. The trustees receive all materials that they and CWAM believe to be reasonably necessary for them to evaluate the Agreement and determine whether to approve the continuation of the Agreement. Those materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and of the Funds' performance benchmarks, (ii) information on the Funds' advisory fees and other expenses, including information comparing the Funds' expenses to those of peer groups of funds and information about any applicable expense caps and fee "breakpoints," (iii) share sales and redemption data, (iv) information about the profitability to CWAM and its affiliates of their relationships with the Funds and potential "fall-out" or ancillary benefits that CWAM and its affiliates may receive as a result of their relationships with the Funds and (v) information obtained through CWAM's response to a questionnaire prepared at the request of the trustees by Bell, Boyd & Lloyd LLC, independent counsel to the Trust and to the independent trustees. The trustees may also consider other information such as (i) CWAM's financial results and financial condition, (ii) each Fund's investment objective and strategies and the size, education and experience of CWAM's investment staffs and their use of technology, external research and trading cost measurement tools, (iii) the allocation of the Funds' brokerage, if any, including allocations to brokers affiliated with CWAM, and the use of "soft" commission dollars to pay Fund expenses or to pay for research products and services, (iv) the resources devoted to, and the record of compliance with, the Funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (v) the response of CWAM and its affiliates to various legal and regulatory proceedings since 2003 and (vi) the economic outlook generally and for the mutual fund industry in particular. In addition, the trustees conferred with, and reviewed the Management Fee Evaluation prepared by, the Trust's Senior Officer, who was appointed by the trustees as contemplated by the Assurance of Discontinuance dated February 9, 2005 among affiliates of CWAM and the Office of the New York Attorney General. A summary of the Management Fee Evaluation is included in this report. Throughout the process, the trustees have the opportunity to ask questions of and request additional materials from CWAM. On July 25, 2005 the board of trustees most recently approved the continuation of the Agreement through October 31, 2005, and on September 28, 2005 the board approved an amended and restated Agreement (the "Amended Agreement") for an initial term ending on July 31, 2006. The board actions followed Committee meetings held in June, July and September 2005. The board determined in the first instance to continue the Agreement through October (rather than for a full year period) pending the resolution of the compensation and incentive plan for key CWAM employees, whose employment agreements were to terminate in December, 2005. Those matters were resolved prior to September 28, 2005. In considering whether to approve the continuation of the Agreement and to approve the Amended Agreement, the trustees, including the independent trustees, did not identify any single factor as determinative, and each weighed the various factors as he or she deemed appropriate. The trustees considered the following matters in connection with their continuation of the Agreement and, except as noted in connection with their approval of the Amended Agreement (collectively with the Agreement, the "Agreements"). Nature, quality and extent of services. The trustees reviewed the nature, quality and extent of CWAM's services to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge gained from the board's regular meetings with management. In addition, the trustees reviewed CWAM's resources and key personnel, especially those who provide investment management services to the Funds. The trustees considered the importance of the continuity of management. At the September 28, 2005 meeting, the trustees considered the fact that Columbia Management, Inc. ("CM") and CWAM had agreed on a new compensation and incentive plan for key CWAM employees. The trustees also considered other services provided to the Funds by CWAM, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, providing support services for the board and board committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various Fund policies and procedures and with applicable securities laws and regulations. The trustees concluded that the nature and extent of the services provided by CWAM to each Fund were appropriate and consistent with the terms of the Agreements, that the quality of those services had been consistent with or superior to quality norms in the industry and that the Funds were likely to benefit from the continued provision of those services. They also concluded that CWAM had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. Performance of the Funds. The trustees considered the short-term and longer-term performance of each Fund. They reviewed information comparing each Fund's performance with the performance of the Fund's benchmark and with the performance of comparable funds and peer groups identified by Lipper Inc. ("Lipper") and Morningstar Associates, LLC ("Morningstar"). They noted that the two domestic Funds, Wanger U.S. Smaller Companies and Wanger Select, have each outperformed their respective benchmarks and Lipper and Morningstar peers. The trustees considered that Lipper and Morningstar ranked Wanger U.S. Smaller Companies first in its peer group for the past five years and Wanger Select first in its peer group for the three and five-year periods. The trustees discussed the performance of the two international Funds, Wanger International Small Cap and Wanger International Select, noting that each Fund's performance had improved over the past two years. They considered that Morningstar ranked Wanger International Small Cap first in its peer group for the one-year period and Lipper ranked it first in its peer group for the three-year period. They also considered that Lipper ranked Wanger International Select first in its peer group for the one-year period and second in its peer group for the three and five-year periods. The trustees concluded that although past performance is not necessarily indicative of future results, the Funds' improving performance record and investment process enhancements were important factors in the trustees' evaluation of the quality of services provided by CWAM under the Agreement. Costs of Services and Profits Realized by CWAM. The trustees examined information on fees and expenses of each Fund in comparison to information for other comparable funds as provided by Lipper and Morningstar. They considered that both the contractual rates of advisory fees and the actual advisory fees for most of the Funds were higher than the median advisory fees of the respective peer groups. The trustees also considered that the expense ratios of each Fund were also higher than the median expense ratios of the respective peer groups. At the July 25, 2005 meeting, at the recommendation 21 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT of the Committee, the board approved a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above, effective August 1, 2005. The trustees reviewed information on the profitability of CWAM in serving as each Fund's investment adviser and of CWAM and its affiliates in all of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other business units. The trustees considered the methodology used by CWAM in determining compensation payable to portfolio managers and the very competitive environment for investment management talent. The trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and profitability of any manager is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the manager's capital structure and cost of capital. However, based on the information available and taking those factors into account, the trustees concluded that the profitability of CWAM regarding each Fund in relation to the services rendered was not unreasonable. The trustees also reviewed CWAM's advisory fees for its institutional separate accounts. Although in most instances its institutional separate account fees for various investment strategies were lower than the advisory fees charged to the Funds with corresponding strategies, the trustees noted that CWAM performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the trustees considered the financial condition of CWAM, which they found to be sound. The trustees concluded that the advisory fees (including the additional breakpoint for Wanger International Small Cap) and other compensation payable by the Funds to CWAM and its affiliates were reasonable in relation to the nature and quality of the services to be provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees CWAM charges to other clients. The trustees noted, however, that they would continue to evaluate the Funds' investment advisory fee rates. The trustees also concluded that the Funds' estimated overall expense ratios, taking into account quality of services provided by CWAM and the investment performance of the Funds, were also reasonable. Economies of Scale. The trustees noted that the advisory fee schedule for each of Wanger U.S. Smaller Companies and Wanger International Small Cap contains two breakpoints that reduce the fee rate on assets above specified levels. They also noted that they had agreed to establish a new breakpoint for Wanger International Small Cap. The trustees concluded that with the additional breakpoint for Wanger International Small Cap, the fee schedule for each Fund would represent a sharing of economies of scale at current asset levels. They agreed, however, to continue their periodic consideration of the Funds' fee structures and economies of scale. Other Benefits to CWAM. The trustees also considered benefits that accrue to CWAM and its affiliates from their relationship with the Funds. The trustees concluded that, other than the services to be provided by CWAM and its affiliates pursuant to the Agreement and the fees payable by the Funds therefor, the Funds and CWAM may potentially benefit from their relationship with each other in other ways. Recognizing that an affiliate of CWAM serves the Funds as transfer agent and receives compensation from the Funds for those services, the trustees determined that such compensation was not unreasonable. They noted that the Funds' transfer agent reported that it made a small profit on its work for the Funds. The trustees also considered CWAM's use of commissions to be paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting the Funds and/or other clients of CWAM. The trustees concluded that CWAM's use of "soft" commission dollars to obtain research products and services was consistent with regulatory requirements and is beneficial to the Funds. They concluded that, although CWAM derives or may derive additional benefits through the use of soft dollars from the Funds' portfolio transactions, the Funds also benefit from the receipt of research products and services to be acquired through commissions paid on the portfolio transactions of other clients of CWAM. New Terms of the Amended Agreement. As previously mentioned, the trustees negotiated a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above. That new breakpoint is reflected in the Amended Agreement. In addition, the Amended Agreement includes representations by CWAM that are substantially similar to those contained in a letter agreement between the Trust and CMG that expired on October 31, 2005. The Amended Agreement provides that: (1) CWAM will endeavor to preserve the autonomy of the Trust; (2) CWAM remain a wholly-owned subsidiary of CMG (or any successor company) as a Chicago-based management firm; (3) CWAM will maintain the investment philosophy and research that the Chicago-based management deems appropriate, research activities separate and dedicated solely to CWAM and its own domestic and international trading activities; (4) CWAM will use its best efforts to maintain information systems that will provide timely and uninterrupted operating information and data consistent with all regulatory and compliance requirements; (5) CWAM's Chicago-based management will have the responsibility and considerable latitude to recruit and compensate (on a competitive basis) investment management personnel and to control travel budgets for analysts consistent with its operational and strategic plans while subject to the approval of CM; and (6) CWAM acknowledges the importance that the Board and its compliance/contract review committee place on full legal and regulatory compliance by CMG, CWAM, and all other Trust service providers and their personnel (collectively, "Providers") and agrees to (i) cooperate fully with the Board, the compliance/contract review committee and the CCO of the Trust with all inquiries by the Trust concerning such compliance by the Providers and (ii) communicate proactively with the Board, the compliance/contract review committee and the CCO of the Trust concerning material compliance matters and any instance of legal or regulatory non-compliance by the Providers of which CWAM is aware and that CWAM deems to be material. Such cooperation and communication by CWAM will be done after receipt of an inquiry or upon learning of any such legal or regulatory non-compliance. Lastly, the Amended Agreement provides that the principal investment management focus and responsibilities of CWAM's portfolio managers and analysts will be dedicated to the Trust and Columbia Acorn Trust. After full consideration of the above factors as well as other factors that were instructive in analyzing the Agreement, the trustees, including all of the independent trustees, concluded that the continuation of the Agreement was in the best interest of each Fund. On July 25, 2005, the trustees continued the Agreement, as revised to include an additional breakpoint for Wanger International Small Cap, through October 31, 2005, and on September 28, 2005, the trustees approved the Amended Agreement. 22 Wanger Select 2005 Annual Report - -------------------------------------------------------------------------------- SPECIAL NOTICE A special meeting of the shareholders was held on November 30, 2005 for the purpose of electing nine trustees.

Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- UNDERSTANDING YOUR EXPENSES As a fund shareholder, you incur two types of costs. There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also ongoing costs, which generally include investment advisory and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. ANALYZING YOUR FUND'S EXPENSES To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in the fund during the reporting period. The information in the following table is based on an initial investment of $1,000.00, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using actual operating expenses and total return for the fund. The amount listed in the "hypothetical" column assumes that the return each year is 5% before expenses and then applies each Fund's actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the reporting period. See the "Compare with other funds" information for details on using the hypothetical data. ESTIMATING YOUR ACTUAL EXPENSES To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period. 1. Divide your ending account balance by $1,000.00. For example, if an account balance was $8,600.00 at the end of the period, the result would be 8.6. 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your fund. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period. July 1, 2005 - December 31, 2005 Account value at the Account value at the Expenses paid during Fund's annualized beginning of the period ($) end of the period ($) the period ($) expense ratio (%)* - ------------------------------------------------------------------------------------------------------------------------------------ Actual Hypothetical Actual Hypothetical Actual Hypothetical - ------------------------------------------------------------------------------------------------------------------------------------ Wanger International Select 1,000.00 1,000.00 1,158.09 1,018.50 7.23 6.77 1.33 - ------------------------------------------------------------------------------------------------------------------------------------ Expenses paid during the period are equal to the fund's annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in the fund's most recent fiscal half-year and divided by 365. Had the investment adviser not waived or reimbursed a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only ongoing costs of investing in the fund. As a shareholder of the fund, you do not incur any transaction costs, such as sales charges, redemption or exchange fees. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. The hypothetical example provided is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds whose shareholders may incur transaction costs. *For the six months ended 12/31/05. COMPARE WITH OTHER FUNDS Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transactional costs, such as sales charges or redemption or exchange fees, that may be incurred by shareholders of other funds. Expenses paid during the period do not include any insurance charges imposed by your insurance company's separate accounts. 1 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- [Graphic: Squirrel] NO ORDINARY PORTFOLIO MANAGERS I began working with Ralph Wanger, founder of Columbia Wanger Asset Management, in 1978. Shortly thereafter he issued the third quarter shareholder report for one of our retail funds. In it he wrote: "...hedonism is in... Let us explore the possibility that we have been going through the oldest cycle of all--from Good to Bad." In order to prove that badness was more profitable than goodness, Ralph tested two portfolios for 36-month price changes. The virtuous portfolio included Angelica, up 45%, and Church's Fried Chicken, up 520%. The wicked portfolio included Playboy, up 600%, and DeBeers Mines, up 59%.1 The wicked portfolio won. Ralph's footnote to his essay read: "This study was done by the usual techniques of Financial Analysis: (A) The stocks chosen had nothing to do with the subject, and (B) The portfolios were readjusted until the answer affirmed the hypothesis." At that point it became very clear to me that Ralph Wanger was no ordinary portfolio manager! Ralph parlayed his legendary shareholder reports into his book, A Zebra in Lion Country.2 The book could have been titled, The Wit and Wisdom of Ralph Wanger. In it Ralph admits that his first quarterly newsletters were serious and stuffy. He said that he gave market and economic forecasts that quickly became outdated. Then he decided, "If most mutual fund communications are both boring and wrong, well then, I figured, I'd rather be lively and wrong." There's a lot of Wisdom in A Zebra in Lion Country. Examples include: "Look for stocks that have basic value but are out of fashion." Ralph also wrote, "The greatest investment profit comes when an ugly duckling becomes a swan." And, "If a company's earnings beat the Merrill Lynch analyst's forecast by 2 cents, that doesn't excite me. I need a long-term reason to own a stock." And Ralph meant long term. "...you can't make five or ten or twenty times your money if you don't hold on to your stocks. Most people are delighted when a stock doubles, and quickly sell to lock in their gain," he wrote in his book. Ralph's long-term thinking was driven home in a report essay he wrote in June 1992: "What really makes for successful investing is having a few enormous hits. In 22 years, I've really had three Super Stocks." Houston Oil & Minerals was one. Houston Oil cost $220,000 in 1973 and went to $5.3 million in 1977. Another was Cray Research, which cost $1.5 million in 1978 and was worth $20 million in 1985. International Game Technology, a maker of slot machines, cost $5 million in 1988 and was worth $80 million by June 1992.3 Ralph also had his share of disasters. He wrote in that 1992 report, "There is one stock we tried to sell for two years and never got a bid on any of it. A stock like that just slides from 4 to 3 to 2 to 1 and finally disappears..." Ralph said, "It's kind of like a doctor saying don't worry about it, it's just going to shrivel up and fall off." Atchison Casting, an owner of steel foundries, was a painful example of this. Ralph began purchasing the stock in 1994 and it ended up being nearly worthless when it was sold in 2003. The wisdom here is that small-cap investing can be a winner's game. Let your winners run. On any individual stock, one can possibly make several thousand percent, but the most that one can lose is 100%. Small-cap investors will have some big percentage losers, but damage to portfolios can be minor as long as investors don't keep throwing money at them and if they maintain a well-diversified portfolio. How did Ralph use his genius and wisdom to build a successful firm? A few years after I joined Ralph we had a heated discussion about a stock. The next day I asked him if I had crossed the line during our debate. He looked at me kind of puzzled and said, course not, if we always agreed, why would I need you?" Ralph always respected differing opinions and created a culture of intellectual freedom. In an investment world full of wishful thinking, Ralph also demanded intellectual honesty. The ability to ask tough questions, get sound answers, discover good businesses, detect strong managers and then value stocks appropriately, requires intellectual honesty. Then it's time to act. I remember an analyst saying that a stock trades by appointment and Ralph responding, "Then make an appointment and buy it!" The culture that Ralph fostered allowed Columbia Wanger Asset Management to grow and helped its shareholders to prosper. Leah Zell's contribution to Columbia Wanger Asset Management has also been huge and complementary to Ralph's. Leah seemed to have the ability to see around corners strategically and make quick, good decisions. When Leah joined our team in 1984, she began as a domestic analyst following mostly real estate and retail stocks. Leah then became our first foreign analyst. She successfully launched our first international retail mutual fund, Acorn International, realizing great investment results, and taking the Fund from zero to one billion dollars in assets under management in 14 months. Of course, she could not have done it without a team. Leah built the international area at Columbia Wanger Asset Management. International investing requires all the skills needed for domestic investing, and more. At Columbia Wanger, we like to hire international analysts who also have language skills and cultural 2 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- knowledge. In a number of cases, Leah successfully mentored new analysts who had these traits and fine financial skills but had a lot to learn about security analysis. We at Columbia Wanger Asset Management are happy that Ralph and Leah kept their offices with us and have been advisors over the last two years. We've gotten good advice, but Ralph and Leah made it clear that the decisions were ours. In our semiannual report we published Ralph's last column, which appeared in this section. Ralph once said of writing his essays, "It is fun for me and only mildly irritating to our shareholders." We are grateful to have had Ralph's and Leah's presence and wisdom for all these years. On September 30, 2005, they retired from their advisory roles with the firm. DOMESTIC SMALL-CAP CYCLE Small caps have outperformed large caps for over six years now; by our reckoning, small caps bottomed vs. large caps in March 1999. The small-cap Russell 2500 Index returned 110% from that date through December 31, 2005, far outpacing the S&P 500, which returned 8%. In the past, small-cap stocks had long cycles of out- and under-performance vs. large caps. There is no science and there is no magic in predicting the exact top of a small-cap cycle. Perhaps small caps will continue to outperform--some believe small caps will outperform as long as rapid earnings growth continues and some others believe outperformance will persist until the overall market turns. Numerous economists are predicting higher inflation rates, and small caps did relatively well during the inflationary periods of the 1970s. However, when looking at price-to-earnings ratios, small caps appear expensive vs. large caps. Using another measure, price-to-book value, small caps appear somewhat more reasonably priced. While we don't think domestic small caps are back to their all-time relative high valuations, we do think small-cap domestic stocks on average are no longer cheap. We do not predict market cycles. We stick to what we believe we do best: buying reasonably priced small- and mid-cap stocks and when they enter periods of higher valuations, we try to become more selective. Over time this consistently applied approach has weathered the Funds through a variety of market cycles. While we certainly can't predict what the future holds, the best defense against unknown market factors is diversification across assets, which is a prudent and time-tested investment strategy. COLUMBIA WAM NEWS We are pleased to announce that Satoshi Matsunaga has joined our international analyst team covering Japan. He came on board in September. Before joining Columbia Wanger Asset Management, he was with Compass Advisers in New York. Satoshi holds an MBA from the University of Michigan and a bachelor's in economics from Keio University in Tokyo, Japan. As a Japanese national, Satoshi brings first-hand knowledge of the country and culture. After the close of the period, we hired a new energy analyst. In January, William Doyle came on board. Bill was most recently a manager of PPM America's credit analysis team where part of his responsibilities included following the high yield energy sector. Bill's degrees include an MBA from Loyola University in Chicago and bachelor's degrees in finance and history from Illinois State University. We are pleased to welcome Satoshi and Bill to the team. photo of: CHARLES P. MCQUAID /S/ CHARLES P. MCQUAID CHARLES P.

Wanger International Select ended the year up 16.43% vs. a 20.35% gain for the S&P/Citigroup World ex-US Cap Range $2-10B Index. An underweight in Japan and a pull back in energy stock performance in the fourth quarter hurt the Fund's performance relative to its benchmark. Argentina's Tenaris, a multinational steel pipe manufacturer, topped the annual winner charts with a 144% gain. Canada's Talisman Energy, an oil and gas producer, increased 102%. Outside the energy sector, UK freight forwarder Exel increased 56% in the year and the Fund's investment in Hong Kong exchange operator Hong Kong Exchanges & Clearing increased 61%. The Japanese market rallied late in the year as foreign investors, motivated by signs of an improving economy, poured money into that market. Hoya, a maker of opto-electrical components and eyeglass lenses, rose 28%. Industrial lighting company Ushio gained 25%. Beverage distributor Ito En increased 19%. Daito Trust Construction, an apartment developer, had an 11% gain for the year. Losers for the year included Compass Group, a UK concession and contract caterer, off 25% due to pricing competition in that market. Global Bio-Chem Technology Group, a Hong Kong refiner of corn-based commodities, fell more than 32% in the year due to weakness in some of its commodity prices. Japanese electronics manufacturer Funai Electric was off 32% due to increases in raw material costs. Looking forward to 2006, we will work to increase the Fund's weighting in Japan. To achieve this goal, we are in the process of hiring an analyst to enhance our coverage of Japan. Elsewhere we will continue to follow our bottom-up investment approach to find what we believe to be the best stocks for your portfolio. On December 7, 2005, Christopher Olson was named lead portfolio manager of Wanger International Select. Chris had previously been a co-manager on this Fund.

This graph compares the results of $10,000 invested in Wanger International Select on February 1, 1999 (the date the Fund began operations) through December 31, 2005, to the S&P/Citigroup World ex-US Cap Range $2-10B Index, with dividends and capital gains reinvested. DUE TO ONGOING MARKET VOLATILITY, PERFORMANCE IS SUBJECT TO SUBSTANTIAL SHORT-TERM FLUCTUATIONS. Wanger International Select is a diversified fund that invests in the stocks of medium- to larger-size companies with market capitalizations of $2 to $25 billion at the time of initial purchase. Prior to 2/1/02, Wanger International Select was a non-diversified fund, meaning that the performance of its holdings would have a greater impact on Wanger International Select's total return and may make the Fund's returns more volatile than a more diversified international fund. Mid-cap stocks are more volatile and may be less liquid than large-cap stocks. 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. 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. - -------------------------------------------------------------------------------- RESULTS TO DECEMBER 31, 2005 4th quarter 1 year WANGER INTERNATIONAL SELECT 3.64% 16.43% S&P/Citigroup World ex-US Cap Range $2-10B Index 6.50 20.35 MSCI EAFE 4.08 13.54 Lipper International Funds Index 4.75 15.67 NAV AS OF 12/31/05: $19.63 Performance numbers reflect all Fund expenses but do not include any insurance charge imposed by your insurance company's separate accounts.

See accompanying notes to financial statements. 11 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 1. NATURE OF OPERATIONS Wanger International Select (known prior to May 1, 2004 as Wanger Foreign Forty), (the "Fund") is a series of Wanger Advisors Trust (the "Trust"), an open-end management investment company organized as a Massachusetts business trust. The investment objective of the Fund is to seek long-term growth of capital. The Fund is available only for allocation to certain life insurance company separate accounts established for the purpose of funding qualified and non-qualified variable annuity contracts, and variable life insurance policies and may also be offered directly to certain types of pension plans and retirement arrangements. 2. SIGNIFICANT ACCOUNTING POLICIES SECURITY VALUATION Securities of the Fund are valued at market value or, if a market quotation for a security is not readily available or is deemed not to be reliable because of events or circumstances that have occurred between the market quotation and the time as of which the security is to be valued, the security is valued at a fair value determined in accordance with procedures established by the Board of Trustees. 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 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. Short-term debt obligations 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 readily available and any other assets are valued as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. The Trust has retained an independent statistical fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security. REPURCHASE AGREEMENTS The Fund may engage in repurchase agreement transactions. The Fund, through its custodians, 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 repurchase prices including interest. 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 Fund. Interest income is recorded on an accrual basis and includes amortization of discounts on short-term debt obligations and on long-term debt obligations when required for federal income tax purposes. Realized gains and losses from security transactions are reported on an identified cost basis. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. 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 ("the Exchange") on each day the Exchange is open for trading by dividing the total value of the Fund's investments and other assets, less liabilities, by the number of Fund shares outstanding. CUSTODY FEES/CREDITS Custody fees are reduced based on the Fund's cash balances maintained with the custodian. The Fund could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. The amount is disclosed as a reduction of total expenses in the Statement of Operations. FEDERAL INCOME TAXES The Fund has complied with the provisions of the Internal Revenue Code available to regulated investment companies and, in the manner provided therein, distributes all its 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. INDEMNIFICATION In the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties which provide general indemnities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims against the Fund. Also, under the Trust's organizational documents, the Trustees and Officers of the Trust are indemnified against certain liabilities that may arise out of their duties to the Trust. However, based on experience, the Fund expects the risk of loss due to these warranties and indemnities to be minimal. FOREIGN CAPITAL GAINS TAXES Realized gains in certain countries may be subject to foreign taxes at the fund level, at rates ranging from 10%-15%. The Fund accrues for such foreign taxes on net realized and unrealized gains at the appropriate rate for each jurisdiction. DISTRIBUTIONS TO SHAREHOLDERS Distributions to shareholders are recorded on the ex-date. 3. FEDERAL TAX INFORMATION The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund's capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended December 31, 2005, permanent book and tax basis differences resulting primarily from differing treatments for foreign currency 12 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS transactions and passive foreign investment company ("PFIC") adjustments were identified and reclassified among the components of the Fund's net assets as follows: OVERDISTRIBUTED ACCUMULATED PAID IN NET INVESTMENT LOSS NET REALIZED LOSS CAPITAL --------------------------------------------------------------- $(6,788) $6,788 $-- Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. The tax character of distributions paid during the year ended December 31, 2005 was as follows: DECEMBER 31, 2005 DECEMBER 31, 2004 ----------------- ----------------- Distributions paid from: Ordinary Income* $770,742 $87,061 * For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of December 31, 2005, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM NET UNREALIZED INCOME CAPITAL GAINS APPRECIATION* --------------------------------------------------------------- $152,151 $-- $11,506,706 * The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales, and PFIC adjustments. The following capital loss carryforwards, determined as of December 31, 2005, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: YEAR OF CAPITAL LOSS EXPIRATION CARRYFORWARDS - ---------- ------------- 2010 $ 11,505 2011 982,004 - ---------- ------------- Total $993,509 Expired capital loss carryforwards, if any, are recorded as a reduction of paid-in capital. Capital loss carryforwards of $3,581,121 were utilized during the year ended December 31, 2005 for the Fund. 4. TRANSACTIONS WITH AFFILIATES Columbia Wanger Asset Management, L.P., ("Columbia WAM") a wholly owned subsidiary of Columbia Management, Inc. (CM), which in turn is an indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), furnishes continuing investment supervision to the Fund and is responsible for the overall management of the Fund's business affairs. Effective March 8, 2005, under the Fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 0.99% of average daily net assets. Prior to March 8, 2005, under the Fund's investment management agreement, fees are accrued daily and paid monthly to Columbia WAM at the annual rate of 1.00% of average daily net assets. In accordance with the terms of the Assurance of Discontinuance with the New York Attorney General, Columbia WAM waived a portion of the fees payable under the Fund's investment management agreement so that those fees are retained at 0.99% of average daily net assets. The fee waiver was effective from January 1, 2005 through March 8, 2005, but applied as if it had gone into effect on December 1, 2004. Fees waived by Columbia WAM amounted to $674 for the year ended December 31, 2005. The investment advisory agreement also provides that through April 30, 2006 Columbia WAM will reimburse the Fund to the extent that ordinary operating expenses (computed based on net custodian fees) exceed an annual percentage of 1.45% of average daily net assets. There was no reimbursement for the year ended December 31, 2005. 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. For the year ended December 31, 2005, the Fund paid $4,319 to trustees not affiliated with Columbia WAM. The Board of Trustees appointed a Chief Compliance Officer to the Fund in accordance with federal securities regulations. The Fund will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. These expenses are disclosed separately as "Compliance fees" on the Statement of Operations. Columbia Management Distributors, Inc. (formerly Columbia Funds Distributor, Inc.), a wholly owned subsidiary of BOA, serves as the principal underwriter of the Trust and receives no compensation for its services. Columbia Management Services, Inc. (formerly Columbia Funds Services, Inc.) (the "Transfer Agent"), a wholly-owned subsidiary of BOA, provides shareholder services to the Fund and has contracted with Boston Financial Data Services ("BFDS") to serve as subtransfer agent. For such services, the Transfer Agent receives a fee, paid monthly, at the annual rate of $21.00 per open account. The Transfer Agent also receives reimbursement for certain out-of-pocket expenses. During the year ended December 31, 2005, the Fund engaged in purchase and sales transactions with funds that have a common investment advisor (or affiliated investment advisors), common Directors/Trustees, and/or common Officers. These purchase and sale transactions complied with the provisions of Rule 17a-7 under the Investment Company Act of 1940 and were $419,565 and $5,131,823, respectively. 5. BORROWING ARRANGEMENTS The Trust participates in a $150,000,000 credit facility, which was entered into to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at rate per annual equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. No amounts were borrowed under this facility for the year ended December 31, 2005. 6. FUND SHARE TRANSACTIONS Proceeds and payments on Fund shares as shown in the statement of changes in net assets are in respect of the following numbers of shares: Year ended Year ended December 31, 2005 December 31, 2004 - -------------------------------------------------------------------------------- Shares sold 688,890 1,041,265 - -------------------------------------------------------------------------------- Shares issued in reinvestment of dividend distributions 43,155 6,025 - -------------------------------------------------------------------------------- Less shares redeemed 537,836 940,310 - -------------------------------------------------------------------------------- Net increase in shares outstanding 194,209 106,980 13 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 7. INVESTMENT TRANSACTIONS The aggregate cost of purchases and proceeds from sales other than short-term obligations for the year ended December 31, 2005 were $22,173,086 and $18,480,720. 8. LEGAL PROCEEDINGS Columbia WAM, Columbia Acorn Trust, another mutual fund family advised by Columbia WAM, and the trustees of Colombia Acorn Trust, are named as defendants in class and derivative complaints which have been consolidated in a Multi-District Action in the federal district court for the District of Maryland. These lawsuits contend that defendants permitted certain investors to market time their trades in certain Columbia Acorn Funds. The Multi-District Action is ongoing. However, all claims against Columbia Acorn Trust and the independent trustees of Columbia Acorn Trust have been dismissed. Columbia WAM, the Columbia Acorn Funds and the trustees of Columbia Acorn Trust are defendants in a consolidated lawsuit filed in the federal district court of Massachusetts alleging that Columbia WAM used Fund assets to make undisclosed payments to brokers as an incentive for the brokers to market the Columbia Acorn Funds over the other mutual funds to investors. The complaint alleges Columbia WAM and the Trustees of the Trust breached certain common laws duties and federal laws. All claims against all defendants in this lawsuit have been dismissed. However, the plaintiffs have filed a notice of appeal with the First Circuit Court of Appeals. The Columbia Acorn Trust and Columbia WAM are also defendants in a class action lawsuit that alleges, in summary, that the Columbia Acorn Trust and Columbia WAM exposed shareholders of Columbia Acorn International Fund to trading by market timers by allegedly (a) failing to properly evaluate daily whether a significant event affecting the value of that Fund's securities had occurred after foreign markets had closed but before the calculation of the Funds' net asset value ("NAV"); (b) failing to implement the Fund's portfolio valuation and share pricing policies and procedures; and (c) failing to know and implement applicable rules and regulations concerning the calculation of NAV (the "Fair Valuation Lawsuit"). The Seventh Circuit ruled that the plaintiffs' state law claims were preempted under federal law resulting in the dismissal of plaintiffs' complaint. However, plaintiffs are in the process of appealing that decision before the United States Supreme Court. On March 21, 2005, a class action complaint was filed against the Columbia Acorn Trust and Columbia WAM seeking to rescind the Contingent Deferred Sales Charges assessed upon redemption of Class B shares of Columbia Acorn Funds due to the alleged market timing of the Columbia Acorn Funds. In addition to the rescission of sales charges, plaintiffs seek recovery of actual damages, attorneys' fees and costs. The case has been transferred to the Multi-District Action in the federal district court of Maryland. The Columbia Acorn Trust and Columbia WAM intend to defend these suits vigorously. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Funds. In connection with the events described in detail above, various parties have filed suit against certain funds, their Boards and/or BOA (and affiliated entities). These suits are ongoing. However, based on currently available information, the Columbia Acorn Trust believes that the likelihood that these lawsuits will have a material adverse impact on any fund is remote, and Columbia WAM believes that the lawsuits are not likely to materially affect its ability to provide investment management services to the Funds. For the year ended December 31, 2005, CM has assumed $7,116 in consulting services and legal fees incurred by the Fund in connection with these matters. 14 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of Wanger International Select Fund: In our opinion, the accompanying statement of assets and liabilities, including the statement of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Wanger International Select Fund (a series of the Wanger Advisors Trust, hereinafter referred to as the "Fund") at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. The financial highlights of the Fund for the periods ended December 31, 2003 and prior were audited by other independent auditors whose report dated February 6, 2004 expressed an unqualified opinion on those financial statements. PricewaterhouseCoopers LLP Chicago, Illinois February 14, 2006 15 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- [EXCERPTS FROM:] WANGER ADVISORS TRUST Management Fee Evaluation of the Senior Officer Prepared Pursuant to the New York Attorney General's Assurance of Discontinuance July 2005 16 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- Introduction The New York Attorney General's Assurance of Discontinuance ("Order") entered into by Columbia Management Advisors, Inc. ("CMAI") and Columbia Funds Distributor, Inc., ("CFDI" and collectively with "CMAI," "CMG") in February 2005, allows CMAI to manage or advise a mutual fund, including the Wanger Advisors Trust's family of funds (the "WAT Funds" or "WAT" or "Trust"), only if the trustees of the WAT Funds appoint a "Senior Officer" to perform specified duties and responsibilities. One of these responsibilities includes "managing the process by which proposed management fees (including but not limited to, advisory fees) to be charged the WAT Fund[s] are negotiated so that they are negotiated in a manner which is at arms' length and reasonable and consistent with this Assurance of Discontinuance." The Order also provides that the Board of Trustees of the WAT Funds ("Board") must determine the reasonableness of proposed "management fees" by using either an annual competitive bidding process supervised by the Senior Officer or Independent Fee Consultant, or by obtaining "an annual independent written evaluation prepared by or under the direction of the Senior Officer or the Independent Fee Consultant." "Management fees" are only part of the costs and expenses paid by mutual fund shareholders. The expenses can vary depending upon the class of shares held but usually include: (1) investment management or advisory fees to compensate analysts and portfolio managers for stock research and portfolio management, as well as the cost of operating a trading desk; (2) administrative expenses incurred to prepare registration statements and tax returns, calculate the Funds' net asset values, maintain effective compliance procedures and perform recordkeeping services; (3) transfer agency costs for establishing accounts, accepting and disbursing funds, as well as overseeing trading in Fund shares; (4) custodial expenses incurred to hold the securities purchased by the Funds; and (5) distribution expenses, including commissions paid to brokers that sell the Fund shares to investors. Columbia Wanger Asset Management, L.P. ("CWAM"), the adviser to the WAT Funds, has proposed that the Trust enter into an agreement that "bundles" the first two categories listed above: advisory and administrative services. The fees paid under this agreement are referred to as "management fees." Other fund expenses are governed by separate agreements, in particular agreements with two CWAM affiliates: CFDI, the broker-dealer that underwrites and distributes the WAT Funds' shares, and Columbia Funds Services, Inc. ("CFSI"), the Funds' transfer agent. In conformity with the terms of the Order, this evaluation, therefore, addresses only the advisory and administrative contract between CWAM and the Trust, and does not extend to the other agreements. According to the Order, the Senior Officer's evaluation must consider at least the following: (1) Management fees (including components thereof) charged to institutional and other clients of CWAM for like services; (2) Management fees (including any components thereof) charged by other mutual fund companies for like services; (3) Costs to CWAM and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit; (4) Profit margins of CWAM and its affiliates from supplying such services; (5) Possible economies of scale as the WAT Funds grow larger; and (6) The nature and quality of CWAM's services, including the performance of each WAT Fund. On November 17, 2004, the Board appointed me, Robert Scales, Senior Officer under the Order. The Board also determined not to pursue a competitive bidding process and instead, charged me with the responsibility of evaluating the WAT Funds' proposed advisory and administrative fee contract with CWAM in conformity with the requirements of the Order. This Report is an annual evaluation required under the Order. In discharging their responsibilities, the independent Trustees have also consulted independent, outside counsel. * * * This evaluation was performed in cooperation and regular communication with the Compliance/Contract Renewal Committee of the Board. Process and Independence The objectives of the Order are to ensure the independent evaluation of the advisory fees paid by the WAT Funds as well as to ensure that all relevant factors are considered. In my view, the contract renewal process has been conducted at arms-length and with independence in gathering, considering and evaluating relevant data. For example, the selection of fund peer groups is critical in assessing a fund's relative performance and cost. I have required Lipper and Morningstar, Inc. to prepare their reports without input or commentary from CWAM; the engagement letters with them reflect this requirement. As a result, the peer groups reflected in the Morningstar, Inc. and Lipper reports were determined independently. After submission of the reports, I asked CWAM to comment on them to avoid errors and to establish a clear record of CWAM's views on which funds, in its judgment, constitute an appropriate peer group. Similarly, I discussed CWAM's profitability analysis with its management but also sought the independent views of Ernst &Young on the reasonableness of CWAM's cost allocation methodology and on the adequacy of the financial data it provided. The evaluation of CWAM's profitability was performed in the context of the limited industry data available. My evaluation of the advisory contract was shaped by my experience as WAT's Chief Compliance Officer ("CCO"). As CCO, I report solely to the Board and have no reporting obligation to or employment relationship with CMG or its affiliates, except for administrative purposes. This too contributes to the independence of this evaluation. I have made several comments on compliance matters in evaluating the quality of service provided by CWAM and CMG. 17 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- Finally, this Report, its supporting materials and the data contained in other materials submitted to the Compliance/Contract Renewal Committee of the Board, in my view, provide a thorough factual basis upon which the Board, in consultation with independent counsel as it deems appropriate, may conduct management fee negotiations that are in the best interests of the WAT Funds' shareholders. * * * VI. Conclusions My review of the data and other material above leads to the following conclusions with respect to the factors identified in the Order. 1. Performance. The WAT Funds generally have achieved outstanding performance and rank very favorably against their peers. The international funds have good recent performance records, but weaker long-term performance relative to the domestic WAT Funds. Recent management changes have been followed by improved performance. The domestic WAT Funds and International Select typically achieve their performance with less risk than their competitors; relative risks are greater for International Small Cap. 2. Management Fees relative to Peers. The management fee rankings of the Funds are generally well below the respective medians and, hence, less favorable to shareholders than their peer group funds. 3. Administrative Fees. The WAT Funds pay a bundled fee that combines advisory fees and administrative expense, so ranking these fees separately was not possible. 4. Management Fees relative to Other Accounts. CWAM's focus is its mutual funds. It does not actively seek to manage separate or institutional accounts. The few institutional accounts it does manage vary in rate structures. Some pay advisory fees commensurate with or higher than the WAT Funds. In a few instances, however, sub-advised accounts pay lower management fees than do the WAT Funds. 5. Costs to CWAM and its Affiliates. CWAM's costs do not appear excessive, and, in my view, it uses appropriate methodologies to allocate overhead costs. CWAM's affiliates do not appear to profit indirectly from CWAM's management agreement with the WAT Funds. 6. Profit Margins. CWAM's firm-wide profit margins are at the upper end of the industry, though these comparisons are hampered by limited industry data. High profit margins are not unexpected for firms that manage large, successful funds and have provided outstanding investment performance for investors. Profit margins for the WAT Funds are lower than the margins for other accounts managed by CWAM because of payments made to intermediaries that offer the WAT Funds through variable annuity products. CMAI, the Funds' administrator, currently experiences losses rather than profits, in connection with its activities relating to the WAT Funds. 7. Economies of Scale. Economies of scale do exist at CWAM and will expand, if the assets of the WAT Funds get larger. They are, however, only partially reflected in the management fee schedule for two of the four WAT Funds. If the Funds' assets continue to grow, under the Funds' current fee schedules, shareholders might not benefit in a manner generally commensurate with CWAM's increased profits 8. Nature and quality of services. This category includes a variety of considerations that are difficult to quantify, yet can have a significant bearing on the performance of the WAT Funds. Several areas merit comment. a. Continuity of Management. It is critical that capable and experienced portfolio managers remain committed to the Funds and are able to hire and retain analysts to assist them. CWAM must have in place appropriate incentive plans that align its management's interests with those of investors. Further, CWAM must maintain the independence of its investment process. It should also be supported by effective information technology. b. Compliance. CWAM has an effective compliance program and a variety of related services that are valuable to shareholders, such as, systems to ensure best execution of portfolio transactions and the daily review of security prices to ensure accuracy of the WAT Funds' NAV. c. Administration Services. The WAT Funds benefit from a variety of administrative services that are performed by CWAM and CMAI, including preparation of registration statements, calculation of Fund NAV's, accounting services, shareholder services, and other functions In my opinion, these conclusions, taken together, generally support the reasonableness of the proposed management agreement. In reaching this conclusion, I weighed heavily the outstanding performance of the WAT Funds relative to their peers. Performance is an investor's first concern. The expense incurred by shareholders to enjoy this performance is, however, high relative to competing funds, though expenses for the WAT Funds are (with one exception) comparable to the parallel Acorn Funds. Nonetheless, a more complete breakpoint schedule could address this issue as well as share with investors more fully the benefits of economies of scale. 18 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- VII. Recommendations The Trustees should consider the following proposals to address the issues identified in this Report. Some of these recommendations require the collection and evaluation of more data. This work cannot be accomplished effectively before the expiration of the existing advisory contract on July 31, 2005. Therefore, I recommend that the Trustees consider extending the existing contract pending consideration of these recommendations. These recommendations do not purport to offer the only avenues to address the opinions and conclusions I have expressed in this Report. Economies of scale, for example, can be addressed in a variety of ways in a management contract. Sound business judgment will guide how any particular area is addressed with due consideration given to all the factors that must be weighed in reaching a management agreement that best serves the WAT Fund shareholders. I believe the Trustees should consider the following: 1. Restructure the management fee schedule beyond the current breakpoints to reflect more fully economies of scale. The Trustees might consider several ways to accomplish this objective, including instituting a two-tier fee structure that incorporates a complex- or CWAM-wide fee (including assets held in separate accounts) and a fund specific fee, with each containing breakpoints to reflect their separate economies of scale. Another approach is to consider uniform breakpoints for all WAT Funds, including breakpoints above and below current asset levels. 2. Conduct further study to ensure that the costs paid to insurance company intermediaries are transparent. The Trustees could consider forming an ad hoc committee to gather and evaluate data regarding CWAM's payments to intermediaries and the services provided by those intermediaries. Such a committee might also seek the assistance of a consultant such as Ernst & Young. 3. Administrative Fees. Administrative and advisory fees could be unbundled to allow greater transparency and to permit distinct comparisons among peers. An administrative fee could also be formulated with a breakpoint schedule that shares the economies of scale available with shareholders. 4. Condition contract renewal on submission of an employment agreements or a management incentive plan designed to ensure the continued employment of senior management, under terms that align management's incentives with the interests of the WAT Funds' shareholders. Any incentive plan should be designed to permit CWAM to attract and retain the highest caliber investment professionals and support them with effective and reliable information technology systems. 5. Review with CWAM its anticipated capacity limitations and the degree to which increased staffing and effective incentives may address those issues. Robert P. Scales Chief Compliance Officer, Senior Vice President and General Counsel July 25, 2005 19 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT The Compliance/Contract Review Committee (the "Committee") of the board of trustees meets on a regular basis and holds special meetings as otherwise necessary or advisable to review the advisory agreement (the "Agreement") of Wanger Advisors Trust (the "Trust") and each series thereof (the "Funds") and determines whether to recommend that the full board approve the continuation of the Agreement for an additional term. The Committee is comprised of three or more trustees, each of whom is an independent trustee, and the Trust's Chief Compliance Officer ("CCO"), who is a non-voting member of the Committee. After the Committee has made its recommendation, the full board, including the independent trustees, determines whether to approve the continuation of the Agreement. In addition, the board, including the independent trustees, considers matters bearing on the Agreement at most of their other meetings throughout the year and meets at least quarterly with the portfolio managers employed by Columbia Wanger Asset Management, L.P. ("CWAM"), the Funds' investment adviser. The trustees receive all materials that they and CWAM believe to be reasonably necessary for them to evaluate the Agreement and determine whether to approve the continuation of the Agreement. Those materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and of the Funds' performance benchmarks, (ii) information on the Funds' advisory fees and other expenses, including information comparing the Funds' expenses to those of peer groups of funds and information about any applicable expense caps and fee "breakpoints," (iii) share sales and redemption data, (iv) information about the profitability to CWAM and its affiliates of their relationships with the Funds and potential "fall-out" or ancillary benefits that CWAM and its affiliates may receive as a result of their relationships with the Funds and (v) information obtained through CWAM's response to a questionnaire prepared at the request of the trustees by Bell, Boyd & Lloyd LLC, independent counsel to the Trust and to the independent trustees. The trustees may also consider other information such as (i) CWAM's financial results and financial condition, (ii) each Fund's investment objective and strategies and the size, education and experience of CWAM's investment staffs and their use of technology, external research and trading cost measurement tools, (iii) the allocation of the Funds' brokerage, if any, including allocations to brokers affiliated with CWAM, and the use of "soft" commission dollars to pay Fund expenses or to pay for research products and services, (iv) the resources devoted to, and the record of compliance with, the Funds' investment policies and restrictions, policies on personal securities transactions and other compliance policies, (v) the response of CWAM and its affiliates to various legal and regulatory proceedings since 2003 and (vi) the economic outlook generally and for the mutual fund industry in particular. In addition, the trustees conferred with, and reviewed the Management Fee Evaluation prepared by, the Trust's Senior Officer, who was appointed by the trustees as contemplated by the Assurance of Discontinuance dated February 9, 2005 among affiliates of CWAM and the Office of the New York Attorney General. A summary of the Management Fee Evaluation is included in this report. Throughout the process, the trustees have the opportunity to ask questions of and request additional materials from CWAM. On July 25, 2005 the board of trustees most recently approved the continuation of the Agreement through October 31, 2005, and on September 28, 2005 the board approved an amended and restated Agreement (the "Amended Agreement") for an initial term ending on July 31, 2006. The board actions followed Committee meetings held in June, July and September 2005. The board determined in the first instance to continue the Agreement through October (rather than for a full year period) pending the resolution of the compensation and incentive plan for key CWAM employees, whose employment agreements were to terminate in December, 2005. Those matters were resolved prior to September 28, 2005. In considering whether to approve the continuation of the Agreement and to approve the Amended Agreement, the trustees, including the independent trustees, did not identify any single factor as determinative, and each weighed the various factors as he or she deemed appropriate. The trustees considered the following matters in connection with their continuation of the Agreement and, except as noted in connection with their approval of the Amended Agreement (collectively with the Agreement, the "Agreements"). Nature, quality and extent of services. The trustees reviewed the nature, quality and extent of CWAM's services to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge gained from the board's regular meetings with management. In addition, the trustees reviewed CWAM's resources and key personnel, especially those who provide investment management services to the Funds. The trustees considered the importance of the continuity of management. At the September 28, 2005 meeting, the trustees considered the fact that Columbia Management, Inc. ("CM") and CWAM had agreed on a new compensation and incentive plan for key CWAM employees. The trustees also considered other services provided to the Funds by CWAM, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, providing support services for the board and board committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various Fund policies and procedures and with applicable securities laws and regulations. The trustees concluded that the nature and extent of the services provided by CWAM to each Fund were appropriate and consistent with the terms of the Agreements, that the quality of those services had been consistent with or superior to quality norms in the industry and that the Funds were likely to benefit from the continued provision of those services. They also concluded that CWAM had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. Performance of the Funds. The trustees considered the short-term and longer-term performance of each Fund. They reviewed information comparing each Fund's performance with the performance of the Fund's benchmark and with the performance of comparable funds and peer groups identified by Lipper Inc. ("Lipper") and Morningstar Associates, LLC ("Morningstar"). They noted that the two domestic Funds, Wanger U.S. Smaller Companies and Wanger Select, have each outperformed their respective benchmarks and Lipper and Morningstar peers. The trustees considered that Lipper and Morningstar ranked Wanger U.S. Smaller Companies first in its peer group for the past five years and Wanger Select first in its peer group for the three and five-year periods. The trustees discussed the performance of the two international Funds, Wanger International Small Cap and Wanger International Select, noting that each Fund's performance had improved over the past two years. They considered that Morningstar ranked Wanger International Small Cap first in its peer group for the one-year period and Lipper ranked it first in its peer group for the three-year period. They also considered that Lipper ranked Wanger International Select first in its peer group for the one-year period and second in its peer group for the three and five-year periods. The trustees concluded that although past performance is not necessarily indicative of future results, the Funds' improving performance record and investment process enhancements were important factors in the trustees' evaluation of the quality of services provided by CWAM under the Agreement. Costs of Services and Profits Realized by CWAM. The trustees examined information on fees and expenses of each Fund in comparison to information for other comparable funds as provided by Lipper and Morningstar. They considered that both the contractual rates of advisory fees and the actual advisory fees for most of the Funds were higher than the median advisory fees of the respective peer groups. The trustees also considered that the expense ratios of each Fund were also higher than the median expense ratios of the respective peer groups. At the July 25, 2005 meeting, at the recommendation 20 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENT of the Committee, the board approved a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above, effective August 1, 2005. The trustees reviewed information on the profitability of CWAM in serving as each Fund's investment adviser and of CWAM and its affiliates in all of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other business units. The trustees considered the methodology used by CWAM in determining compensation payable to portfolio managers and the very competitive environment for investment management talent. The trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and profitability of any manager is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the manager's capital structure and cost of capital. However, based on the information available and taking those factors into account, the trustees concluded that the profitability of CWAM regarding each Fund in relation to the services rendered was not unreasonable. The trustees also reviewed CWAM's advisory fees for its institutional separate accounts. Although in most instances its institutional separate account fees for various investment strategies were lower than the advisory fees charged to the Funds with corresponding strategies, the trustees noted that CWAM performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the trustees considered the financial condition of CWAM, which they found to be sound. The trustees concluded that the advisory fees (including the additional breakpoint for Wanger International Small Cap) and other compensation payable by the Funds to CWAM and its affiliates were reasonable in relation to the nature and quality of the services to be provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees CWAM charges to other clients. The trustees noted, however, that they would continue to evaluate the Funds' investment advisory fee rates. The trustees also concluded that the Funds' estimated overall expense ratios, taking into account quality of services provided by CWAM and the investment performance of the Funds, were also reasonable. Economies of Scale. The trustees noted that the advisory fee schedule for each of Wanger U.S. Smaller Companies and Wanger International Small Cap contains two breakpoints that reduce the fee rate on assets above specified levels. They also noted that they had agreed to establish a new breakpoint for Wanger International Small Cap. The trustees concluded that with the additional breakpoint for Wanger International Small Cap, the fee schedule for each Fund would represent a sharing of economies of scale at current asset levels. They agreed, however, to continue their periodic consideration of the Funds' fee structures and economies of scale. Other Benefits to CWAM. The trustees also considered benefits that accrue to CWAM and its affiliates from their relationship with the Funds. The trustees concluded that, other than the services to be provided by CWAM and its affiliates pursuant to the Agreement and the fees payable by the Funds therefor, the Funds and CWAM may potentially benefit from their relationship with each other in other ways. Recognizing that an affiliate of CWAM serves the Funds as transfer agent and receives compensation from the Funds for those services, the trustees determined that such compensation was not unreasonable. They noted that the Funds' transfer agent reported that it made a small profit on its work for the Funds. The trustees also considered CWAM's use of commissions to be paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting the Funds and/or other clients of CWAM. The trustees concluded that CWAM's use of "soft" commission dollars to obtain research products and services was consistent with regulatory requirements and is beneficial to the Funds. They concluded that, although CWAM derives or may derive additional benefits through the use of soft dollars from the Funds' portfolio transactions, the Funds also benefit from the receipt of research products and services to be acquired through commissions paid on the portfolio transactions of other clients of CWAM. New Terms of the Amended Agreement. As previously mentioned, the trustees negotiated a new breakpoint for Wanger International Small Cap's fee schedule, reducing fees by 0.10% on net assets of $500 million and above. That new breakpoint is reflected in the Amended Agreement. In addition, the Amended Agreement includes representations by CWAM that are substantially similar to those contained in a letter agreement between the Trust and CM that expired on October 31, 2005. The Amended Agreement provides that: (1) CWAM will endeavor to preserve the autonomy of the Trust; (2) CWAM remain a wholly owned subsidiary of CM (or any successor company) as a Chicago-based management firm; (3) CWAM will maintain the investment philosophy and research that the Chicago-based management deems appropriate, research activities separate and dedicated solely to CWAM and its own domestic and international trading activities; (4) CWAM will use its best efforts to maintain information systems that will provide timely and uninterrupted operating information and data consistent with all regulatory and compliance requirements; (5) CWAM's Chicago-based management will have the responsibility and considerable latitude to recruit and compensate (on a competitive basis) investment management personnel and to control travel budgets for analysts consistent with its operational and strategic plans while subject to the approval of CM; and (6) CWAM acknowledges the importance that the Board and its compliance/contract review committee place on full legal and regulatory compliance by CMG, CWAM, and all other Trust service providers and their personnel (collectively, "Providers") and agrees to (i) cooperate fully with the Board, the compliance/contract review committee and the CCO of the Trust with all inquiries by the Trust concerning such compliance by the Providers and (ii) communicate proactively with the Board, the compliance/contract review committee and the CCO of the Trust concerning material compliance matters and any instance of legal or regulatory non-compliance by the Providers of which CWAM is aware and that CWAM deems to be material. Such cooperation and communication by CWAM will be done after receipt of an inquiry or upon learning of any such legal or regulatory non-compliance. Lastly, the Amended Agreement provides that the principal investment management focus and responsibilities of CWAM's portfolio managers and analysts will be dedicated to the Trust and Columbia Acorn Trust. After full consideration of the above factors as well as other factors that were instructive in analyzing the Agreement, the trustees, including all of the independent trustees, concluded that the continuation of the Agreement was in the best interest of each Fund. On July 25, 2005, the trustees continued the Agreement, as revised to include an additional breakpoint for Wanger International Small Cap, through October 31, 2005, and on September 28, 2005, the trustees approved the Amended Agreement. 21 Wanger International Select 2005 Annual Report - -------------------------------------------------------------------------------- SPECIAL NOTICE A special meeting of the shareholders was held on November 30, 2005 for the purpose of electing nine trustees.

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. (e)(2) The percentage of services described in paragraphs (b) through (d) of this Item approved pursuant to the "de minimis" exception under paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X during both fiscal years ended December 31, 2005 and December 31, 2004 was zero.

During the fiscal years ended December 31, 2005 and December 31, 2004, All Other Fees that were approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X were approximately $104,200 and $93,500, respectively.

(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.
