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 continuing costs, which generally
include investment advisory, Rule 12b-1 fees, and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

ANALYZING YOUR FUND'S EXPENSES

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.

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 12/31/04.

COMPARE WITH OTHER FUNDS

Since all mutual fund companies 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.

   [LOGO] THE MIRACLE YEAR

RALPH WANGER
FOUNDER, ADVISOR AND TRUSTEE
COLUMBIA WANGER ASSET MANAGEMENT, L.P.

1905 was a year of surprises. The first surprise was the victory of the Japanese
over the Russians in the Russo-Japanese War. In May 1905, the untested Japanese
Navy annihilated the Russian fleet at Tsushima. This was the first time a
non-white country had beaten the main force of a European colonial power. The
second unexpected event was in physics. 2005 will be celebrated as the
centennial of Albert Einstein's "Miracle Year."

The journal, ANNALEN DER PHYSIK, volume 17, published three articles in
September 1905 all written by Einstein, an obscure clerk in the Swiss patent
office in Bern. He had an undergraduate degree in physics but no Ph.D (it was
granted a year later). Each of the articles were on a different subject and each
one revolutionized its branch of physics. Einstein's papers created 20th century
physics almost single-handedly.

ATOMS

In 1905 there were different theories about the structure of matter. If you take
a glass of water and pour nine-tenths of it out, you still have a glass with
water in it. What happens if you repeat this process of throwing out 90% of the
water in the glass? After you repeat the process a few more times, you have such
a small amount of water that you can only see it under a microscope, and in a
few more steps the water drop will be too small to be seen even under the
microscope. Can you continue the boring job of splitting water forever or do you
finally get to a point where it isn't water anymore? Of course we know the
answer: Once you get down to a single molecule of water you can't split it and
still say that you have water left. Many leading scientists did not accept the
atomic theory in 1905. Einstein looked at the process called Brownian Motion in
which a grain of pollen or other small object moves around in a random way. (The
same mathematical process makes stock prices jiggle.) He deduced that this
motion was caused by billions of atoms bumping into the pollen grain in an
irregular pattern. He was even able to calculate the size of the atoms involved,
thus proving that atoms really existed.

PHOTONS

In 1905 there was still a basic debate about the nature of light. The greatest
achievement of 19th century physics was Maxwell's set of partial differential
equations governing electromagnetic fields, including light. Maxwell's equations
required that light be a wave. The great Max Planck had introduced the idea of a
quantum of energy in 1900 to get an equation that tracked the spectrum of heat
radiation, but most scientists doubted that a light quantum was "real." Heinrich
Hertz, Philip Lenard and others showed that when a beam of ultraviolet light
shines on a piece of metal you produce an electrical current in the metal. There
was no way to explain the photoelectric effect according to the Maxwell wave
theory of light. The second paper Einstein wrote dealt with the problem of the
photoelectric effect. If you cut the amount of energy in a beam of light by 90%
and keep reducing it, you still have a beam of light. If you keep slicing the
amount of light, does the beam of light keep getting smaller and smaller forever
or do you get down to an "atom" of light that can't be split further? Einstein
proved that there was a tiny amount of light that could not be further divided.
The least amount of light that exists is a single photon (or quantum) of light.
1 The photoelectric effect is explained by photons acting as particles, not as a
wave.

Einstein's discovery of the photon had a number of interesting effects. First,
it led to the development of quantum mechanics and thus to most of 20th century
physics. Second, it won Einstein his only Nobel Prize. Third, it uncovered a
paradox that still puzzles students, the duality of light. If you run an
experiment to show that light is a wave, you can prove it's a wave. If you run
an experiment to show that it's a particle, you can prove it's a particle. This
duality principle contradicts common sense but when you study science you have
to get used to it. The fourth effect was that it made Lenard a life-long enemy
of Einstein. Philip Lenard, who received the Nobel Prize in 1905 for his own
work on cathode rays, was close to the solution but Einstein ended up getting
the credit. Lenard became an unrelenting foe of Einstein, and influenced the
Nobel committee's decision not to give Einstein the prize for his theory of
relativity. Later on, Lenard became an ardent Nazi.

RELATIVITY

In 1905, there was also a debate in scientific circles about speed. If you were
in a really powerful rocket ship in space, and you pushed the throttle forward,
you would speed up. If you kept on increasing the power, would you go ever
faster, or was there an absolute speed limit in the universe that you could not
exceed?

                                       2




                               Wanger U.S. Smaller Companies  2004 Annual Report
- --------------------------------------------------------------------------------

The third paper became the best known, Einstein's special theory of relativity.
It explained that there was a cosmic speed limit, the speed of light. Very odd
things happen when your rocket ship is moving close to the speed of light. Time
slows down and you get shorter, under the Lorentz contraction equation, giving
rise to the limerick:

A sexy young techie named Fisk, Had a motion exceedingly brisk. So fast was his
action The Lorentz contraction Shortened his rod to a disk.

In a very brief paper published later in 1905, Einstein added in a note that his
theory of relativity implied the equation E=mc 2. That solved the paradox of
radioactivity; Mme Curie's radium was producing much more energy then could be
explained by 19th century physics. Einstein showed that radioactive energy was
caused by turning a small amount of mass into a lot of energy.

So we had this technical journal containing three papers written by a man
unknown in science, a non-Ph.D, a non-academic, writing on a German-dominated
field with all the fussiness about rank and reputation that you would expect.
Would anyone care? Einstein did not receive any communication from any
physicists for the first couple months after he published, but in early 1906 Max
Planck read and understood the papers. He wrote to Einstein and sent his
assistant, another important physicist, Max von Laue, to visit Einstein in Bern.
Planck's subsequent endorsement made Einstein acceptable to the community of
physicists, and his papers became required study for all physicists, as they
remain.

The compelling human question: How the heck did Einstein do it? How could one
human being produce three revolutionary papers in one year, on three different
subjects, while carrying a full-time job at the patent office to boot? We can
admire but not explain. The "Miracle Year" commemorates one of the greatest
feats of the human mind ever.

1 PLANCK AND EINSTEIN HAD DISCOVERED THE QUANTUM JUMP, WHICH WAS THE SMALLEST
THING THAT COULD POSSIBLY EXIST IN THE UNIVERSE. MODERN WRITERS, FOR REASONS
DIFFICULT TO EXPLAIN, NOW USE THE PHRASE QUANTUM JUMP TO MEAN A BIG EVENT. WHEN
NON-SCIENTISTS START THROWING AROUND SCIENTIFIC TERMS WITHOUT UNDERSTANDING
THEM, FUNNY THINGS HAPPEN. DON'T GET ME STARTED ON THE HEISENBERG UNCERTAINTY
PRINCIPLE.

INCIDENTALLY, ALBERT EINSTEIN'S FATHER, HERMANN, WAS BORN IN THE WURTTEMBERG
VILLAGE OF BUCHAU, WHERE HIS FAMILY HAD LIVED FOR GENERATIONS. HERMANN MOVED 20
MILES FROM BUCHAU TO THE CITY OF ULM, WHERE ALBERT WAS BORN. MY GREAT-GREAT
GRANDFATHER, JOSEPH KOHN, WAS ALSO FROM BUCHAU AND HE HAD MANY EINSTEINS IN HIS
FAMILY TREE. I AM VERY PROUD OF THE EINSTEIN CONNECTION.

[LOGO] PERFORMANCE REVIEW     WANGER U.S. SMALLER COMPANIES

Photo of ROBERT A. MOHN

ROBERT A. MOHN
PORTFOLIO MANAGER

Wanger U.S. Smaller Companies ended the year up 18.33%. Fund performance matched
the benchmark Russell 2000, also up 18.33%. There was a great deal of pessimism
about the market and the political environment going into the final quarter of
2004. Because of this, many institutional investors were reported to be building
up cash positions. After the elections, the money came back into the markets,
fueling a fierce fourth quarter rally.

Some of our biggest winners were health care stocks, which benefited from the
year-end market surge. Lincare Holdings, a provider of home health care
services, increased 42% in the year on news of a higher than expected government
dispensing fee for respiratory medication. Edwards Lifesciences's heart valves
were big sellers, pumping the stock up 37% for the year.

Technology stocks also did well. Micros Systems, a developer of reservation
systems used in hotels and restaurants, gained 80% for the year. On the telecom
side, Western Wireless gained 59% in 2004 (and even more so far in 2005 on news
that Alltel will be buying the company).

While slightly cooler in the fourth quarter, energy stocks were strong 2004
performers. Quicksilver, a natural gas producer, was up an impressive 128% for
the year. Chicago Bridge & Iron, a leading designer and manufacturer of tanks
used to convert liquified natural gas into pipeline gas, was added to the Fund
in '04 and immediately went to work. For the year the stock was up 65%.

The laggards for the year included southeast supermarket chain Winn Dixie
Stores, down 58%. The Fund no longer holds the stock. Novell, a developer of
open source software, failed to meet earnings targets and declined 36% for the
year. NDCHealth Group fell 27% as ancillary businesses, outside its core health
care claims processing business, collapsed.

Generally speaking, we think companies are operating in a healthy economy that
should provide growth going forward. We will continue to search for what we
believe are winning small-cap stocks selling at good prices.

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 12/31/04, THE FUND'S POSITIONS IN THE HOLDINGS MENTIONED WERE: LINCARE
HOLDINGS, 3.2%; EDWARDS LIFESCIENCES, 1.5%; MICROS SYSTEMS, 2.2%; WESTERN
WIRELESS, 2.2%; QUICKSILVER, 0.5%; CHICAGO BRIDGE & IRON, 1.9%; WINN DIXIE
STORES, 0.0%; NOVELL, 0.9%; NDCHEALTH GROUP, 0.8%.

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, 2004 with the Russell 2000. Dividends and capital gains are reinvested. DUE
TO ONGOING MARKET VOLATILITY, PERFORMANCE IS SUBJECT TO SUBSTANTIAL SHORT-TERM
FLUCTUATIONS. Wanger U.S. Smaller Companies is a diversified fund that invests

company stocks are often more volatile or less liquid than the stocks of larger
companies.

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.

PERFORMANCE NUMBERS REFLECT ALL FUND EXPENSES BUT DO NOT INCLUDE ANY INSURANCE
CHARGE IMPOSED BY YOUR INSURANCE COMPANY'S SEPARATE ACCOUNTS. IF PERFORMANCE
INCLUDED THE EFFECT OF THESE ADDITIONAL CHARGES, IT WOULD BE LOWER.

The Russell 2000 is formed by taking the 3,000 largest U.S. companies and then
eliminating the largest 1,000, leaving a mainly small company index. The S&P
MidCap 400 is a market value-weighted index of 400 U.S. stocks that are in the
next tier down from the S&P 500. The S&P 500 is a broad market-weighted average
of blue-chip U.S. companies. All indexes are unmanaged and include reinvested
dividends. It is not possible to invest directly in an index.

Portfolio holdings will vary in the future.

                               Wanger U.S. Smaller Companies  2004 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 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. Securities for which quotations are not readily available and any
other assets are valued as determined in good faith by 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. 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. 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.

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.

      For the year ended December 31, 2004, permanent book and tax basis
differences resulting primarily from differing treatments for net operating
losses and REIT adjustments were identified and reclassified among the
components of the Fund's net assets as follows:

                Accumulated          Accumulated
               Net Investment       Net Realized
                    Loss              LossPaid             In Capital
               --------------      -------------        --------------
                 $4,751,216            $67,255           $(4,818,471)

      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 differences between book-basis and tax-basis net unrealized
      appreciation/depreciation are primarily due to deferral of losses from
      wash sales.

      Unrealized appreciation and depreciation at December 31, 2004, based on
cost of investments for federal income tax purposes, was:

      Expired capital loss carryforwards, if any, are recorded as a reduction of
paid-in capital.

      Capital loss carryforwards of $30,060,021 were utilized during the year
ended December 31, 2004 for the Fund.

4.  TRANSACTIONS WITH AFFILIATES

Columbia Wanger Asset Management, L.P., ("Columbia WAM") an indirect
wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a
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. Prior to April 1, 2004, Columbia was
a wholly-owned subsidiary of Fleet National Bank, which in turn was a
wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"). On April
1, 2004, Fleet was acquired by BOA.

      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                                              1.00%
   Next $150 million                                                       0.95%
   In excess of $250 million                                               0.90%

      For the year ended December 31, 2004, the Fund's effective investment
advisory fee rate was 0.92%.

      The investment advisory agreement also provides that 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 the average
daily net assets. There was no reimbursement for the year ended December 31,
2004.

      In accordance with the terms of the NYAG Settlement (as defined and
discussed further under Note 8 to these Financial Statements - "Legal
Proceedings"), Columbia WAM waived a portion of the fees payable under the
Fund's investment management agreement so that those fees are retained at the
following rates as a percentage of average daily net assets: 0.990% - up to $100
million; 0.940% - $100 million to $250 million; 0.890% - $250 million and over.
The fee waiver was effective as of February 10, 2005 but applied as if it had
gone into effect on December 1, 2004. The financial statements, as of December
31, 2004, are not reflective of these changes.

      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, 2004, the Fund
paid $150,206 to trustees not affiliated with Columbia WAM. Effective April
2004, 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 on the Statement of Operations.

      Columbia Funds Distributor, Inc. ("CFDI"), an indirect wholly-owned
subsidiary of BOA, serves as the principal underwriter of the Trust and receives
no compensation for its services.

      Columbia Funds Services, Inc. (the "Transfer Agent"), an indirect
wholly-owned subsidiary of BOA, provides shareholder services to the Fund. For
such services, the Transfer Agent receives a fee, paid monthly, at the annual
rate of $28.00 per open account. The Transfer Agent also receives reimbursement
for certain out-of-pocket expenses. Effective February 1, 2004 the Transfer
Agent made the decision to waive the reimbursement for certain out-of-pocket
expenses. Prior to February 1, 2004, the Transfer Agent was entitled to receive
a flat rate charge based on the number of shareholder accounts and transactions.

      An affiliate may include any company in which a fund owns five percent or
more of its outstanding voting shares. On December 31, 2004, 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, 2004, 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 $0 and $1,094,400,
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, 2004.

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:

8. LEGAL PROCEEDINGS

On March 15, 2004, Columbia Management Advisors, Inc. ("Columbia Management"),
the advisor to the Columbia Funds, and CFDI (collectively with Columbia
Management, "Columbia") the distributor of the shares of the Columbia Funds, the
Columbia Acorn Funds and the Wanger Advisors Trust Funds (collectively, "the
Columbia Family of Funds"), entered into agreements in principle with the staff
of the U.S. Securities and Exchange Commission ("SEC") and the Office of the New
York Attorney General ("NYAG") to resolve the proceedings brought in connection
with the SEC's and NYAG's investigations of frequent trading and market timing
in certain Columbia mutual funds. Columbia WAM, the advisor to the Columbia
Acorn Funds and the Wanger Advisors Trust Funds, was not a respondent in either
proceeding nor were any of its officers or directors.

      On February 9, 2005, Columbia entered into an Assurance of Discontinuance
(the "NYAG Settlement") with the NYAG and consented to the entry of a
cease-and-desist order by the SEC (the "SEC Order" and together, the
"Settlements"). The Settlements contain substantially the same terms and
conditions as outlined in the agreements in principle. Although none of the
Wanger Advisors Trust Funds is a party to the Settlement orders, under the terms
of the Settlements and in order for Columbia Management to continue to provide
administrative services to the Wanger Advisors Funds, the Board of Trustees of
the Wanger Advisors Trust Funds agreed to conform to certain governance
requirements, including the election of an independent board chair.

      Under the terms of the SEC Order, Columbia has agreed, among other things,
to: pay $70 million in disgorgement and $70 million in civil money penalties;
cease and desist from violations of the antifraud provisions and certain other
provisions of the federal securities laws; maintain certain compliance and
ethics oversight structures; retain an independent consultant to review
Columbia's applicable supervisory, compliance, control and other policies and
procedures; and retain an independent distribution consultant (see below). The
NYAG Settlement also, among other things, requires Columbia and its affiliates,
Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce
management fees paid by the Columbia Family of Funds, Nations Funds and other
related mutual funds collectively by $32 million per year for five years, for a
projected total of $160 million in management fee reductions based on net assets
as of March 15, 2004. Pursuant to the procedures set forth in the SEC Order, the
settlement amounts will be distributed in accordance with a distribution plan to
be developed by an independent distribution consultant, who is acceptable to the
SEC staff and the independent trustees of the funds. The distribution plan must
be based on a methodology developed in consultation with Columbia and the
independent trustees of the funds and not unacceptable to the staff of the SEC.
More specific information on the distribution plan will be communicated by
Columbia WAM and/or its affiliates at a later date.

      Columbia WAM, the Columbia Acorn Trust, another mutual fund family advised
by Columbia WAM, and the trustees of Columbia Acorn Trust are defendants in
several derivative and class action lawsuits that allege, in summary, defendants
permitted investors to engage in improper trading of shares of various funds in
violation of certain federal and state laws. All of these lawsuits have been
consolidated with similar suits in a Multi-District Litigation proceeding in
Baltimore, Maryland and consolidated class action and derivative complaints have
been filed.

      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
Fund's 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.

      Columbia WAM and the trustees of Columbia Acorn Trust are also defendants
in a lawsuit 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 other mutual funds to investors. The complaint alleges Columbia WAM
and the trustees of Columbia Acorn Trust breached certain common laws duties and
federal laws.

      On January 11, 2005 a putative class action lawsuit was filed in federal
district court in Massachusetts against, among others, the Trustees of the
Columbia Acorn Trust and Columbia WAM. The lawsuit alleges that defendants
violated common law duties to fund shareholders as well as sections of the
Investment Company Act of 1940, by failing to ensure that the Columbia Acorn
Trust funds and other affiliated funds participated in securities class action
settlements for which the funds were eligible. Specifically, plaintiffs allege
that defendants failed to submit Proof of Claims in connection with settlements
of securities class action lawsuits filed against companies in which the funds
held positions. The complaint seeks compensatory and punitive damages, and the
disgorgement of all fees paid to the Columbia WAM and affiliated advisers.

      The Columbia Acorn Trust and Columbia WAM intend to defend these suits
vigorously. The Columbia Acorn Trust does not believe that the pending actions
will have a material adverse effect on the financial statements of any Columbia
Acorn Fund, and Columbia WAM does not believe that the pending actions will have
a material adverse effect on its ability to perform under its contracts with the
Fund.

      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 Fund.

      In connection with the events described in detail above, various parties
have filed suit again certain funds, their Boards and/or BOA (and affiliated
entities). These suits are ongoing. Accordingly, an estimate of the financial
impact of this litigation on any fund, if any, cannot be currently made.

      For the year ended December 31, 2004, CMG has assumed $50,701 in
consulting services and legal fees incurred by the Fund in connection with these
matters.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Effective April 13, 2004, the audit committee of the Trust requested that Ernst
& Young LLP ("E&Y") resign as the auditors of the Fund. Also effective July 14,
2004, upon the recommendation of the audit committee, the Trust selected
PricewaterhouseCoopers LLP ("PWC") as independent registered public accounting
firm to audit the books and records of the Fund for its fiscal year ending
December 31, 2004. The cessation of the relationship with E&Y was based on the
impairment of E&Y's independence resulting from the consummation of the merger
of FleetBoston Financial Corporation and Bank of America Corporation and
accordingly, E&Y's ability to provide audit services to the Fund.

      E&Y's report on the financial statements of the Fund for the past two
years did not contain an adverse opinion or disclaimer of opinion, and was not
qualified or modified as to uncertainty, audit scope or accounting principles.
During the period E&Y was engaged, there were no disagreements with E&Y on any
matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedure which, if not resolved to E&Y's satisfaction, would
have caused it to make reference to that matter in connection with its 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, 2004, the results of its operations, the changes in its net
assets and the financial highlights for the year 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 audit. 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, 2004 by
correspondence with the custodian and brokers, provides a reasonable basis for
our opinion. The statement of changes in net assets for the year ended December
31, 2003 and financial highlights of the Fund for the periods ended December 31,
2003 and prior were audited by other independent auditors report dated February
6, 2004 expressed an unqualified opinion on those financial statements.

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 continuing costs, which generally
include investment advisory, Rule 12b-1 fees, and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

ANALYZING YOUR FUND'S EXPENSES

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.

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 12/31/04.

COMPARE WITH OTHER FUNDS

Since all mutual fund companies 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.

     [LOGO] THE MIRACLE YEAR

RALPH WANGER
FOUNDER, ADVISOR AND TRUSTEE
COLUMBIA WANGER ASSET MANAGEMENT, L.P.

1905 was a year of surprises. The first surprise was the victory of the Japanese
over the Russians in the Russo-Japanese War. In May 1905, the untested Japanese
Navy annihilated the Russian fleet at Tsushima. This was the first time a
non-white country had beaten the main force of a European colonial power. The
second unexpected event was in physics. 2005 will be celebrated as the
centennial of Albert Einstein's "Miracle Year."

The journal, ANNALEN DER PHYSIK, volume 17, published three articles in
September 1905 all written by Einstein, an obscure clerk in the Swiss patent
office in Bern. He had an undergraduate degree in physics but no Ph.D (it was
granted a year later). Each of the articles were on a different subject and each
one revolutionized its branch of physics. Einstein's papers created 20th century
physics almost single-handedly.

ATOMS

In 1905 there were different theories about the structure of matter. If you take
a glass of water and pour nine-tenths of it out, you still have a glass with
water in it. What happens if you repeat this process of throwing out 90% of the
water in the glass? After you repeat the process a few more times, you have such
a small amount of water that you can only see it under a microscope, and in a
few more steps the water drop will be too small to be seen even under the
microscope. Can you continue the boring job of splitting water forever or do you
finally get to a point where it isn't water anymore? Of course we know the
answer: Once you get down to a single molecule of water you can't split it and
still say that you have water left. Many leading scientists did not accept the
atomic theory in 1905. Einstein looked at the process called Brownian Motion in
which a grain of pollen or other small object moves around in a random way. (The
same mathematical process makes stock prices jiggle.) He deduced that this
motion was caused by billions of atoms bumping into the pollen grain in an
irregular pattern. He was even able to calculate the size of the atoms involved,
thus proving that atoms really existed.

PHOTONS

In 1905 there was still a basic debate about the nature of light. The greatest
achievement of 19th century physics was Maxwell's set of partial differential
equations governing electromagnetic fields, including light. Maxwell's equations
required that light be a wave. The great Max Planck had introduced the idea of a
quantum of energy in 1900 to get an equation that tracked the spectrum of heat
radiation, but most scientists doubted that a light quantum was "real." Heinrich
Hertz, Philip Lenard and others showed that when a beam of ultraviolet light
shines on a piece of metal you produce an electrical current in the metal. There
was no way to explain the photoelectric effect according to the Maxwell wave
theory of light. The second paper Einstein wrote dealt with the problem of the
photoelectric effect. If you cut the amount of energy in a beam of light by 90%
and keep reducing it, you still have a beam of light. If you keep slicing the
amount of light, does the beam of light keep getting smaller and smaller forever
or do you get down to an "atom" of light that can't be split further? Einstein
proved that there was a tiny amount of light that could not be further divided.
The least amount of light that exists is a single photon (or quantum) of light.
1 The photoelectric effect is explained by photons acting as particles, not as a
wave.

Einstein's discovery of the photon had a number of interesting effects. First,
it led to the development of quantum mechanics and thus to most of 20th century
physics. Second, it won Einstein his only Nobel Prize. Third, it uncovered a
paradox that still puzzles students, the duality of light. If you run an
experiment to show that light is a wave, you can prove it's a wave. If you run
an experiment to show that it's a particle, you can prove it's a particle. This
duality principle contradicts common sense but when you study science you have
to get used to it. The fourth effect was that it made Lenard a life-long enemy
of Einstein. Philip Lenard, who received the Nobel Prize in 1905 for his own
work on cathode rays, was close to the solution but Einstein ended up getting
the credit. Lenard became an unrelenting foe of Einstein, and influenced the
Nobel committee's decision not to give Einstein the prize for his theory of
relativity. Later on, Lenard became an ardent Nazi.

RELATIVITY

In 1905, there was also a debate in scientific circles about speed. If you were
in a really powerful rocket ship in space, and you pushed the throttle forward,
you would speed up. If you kept on increasing the power, would you go ever
faster, or was there an absolute speed limit in the universe that you could not
exceed?

                                        2




                              Wanger International Small Cap  2004 Annual Report
- --------------------------------------------------------------------------------

The third paper became the best known, Einstein's special theory of relativity.
It explained that there was a cosmic speed limit, the speed of light. Very odd
things happen when your rocket ship is moving close to the speed of light. Time
slows down and you get shorter, under the Lorentz contraction equation, giving
rise to the limerick:

A sexy young techie named Fisk, Had a motion exceedingly brisk. So fast was his
action The Lorentz contraction Shortened his rod to a disk.

In a very brief paper published later in 1905, Einstein added in a note that his
theory of relativity implied the equation E=mc 2. That solved the paradox of
radioactivity; Mme Curie's radium was producing much more energy then could be
explained by 19th century physics. Einstein showed that radioactive energy was
caused by turning a small amount of mass into a lot of energy.

So we had this technical journal containing three papers written by a man
unknown in science, a non-Ph.D, a non-academic, writing on a German-dominated
field with all the fussiness about rank and reputation that you would expect.
Would anyone care? Einstein did not receive any communication from any
physicists for the first couple months after he published, but in early 1906 Max
Planck read and understood the papers. He wrote to Einstein and sent his
assistant, another important physicist, Max von Laue, to visit Einstein in Bern.
Planck's subsequent endorsement made Einstein acceptable to the community of
physicists, and his papers became required study for all physicists, as they
remain.

The compelling human question: How the heck did Einstein do it? How could one
human being produce three revolutionary papers in one year, on three different
subjects, while carrying a full-time job at the patent office to boot? We can
admire but not explain. The "Miracle Year" commemorates one of the greatest
feats of the human mind ever.

1 PLANCK AND EINSTEIN HAD DISCOVERED THE QUANTUM JUMP, WHICH WAS THE SMALLEST
THING THAT COULD POSSIBLY EXIST IN THE UNIVERSE. MODERN WRITERS, FOR REASONS
DIFFICULT TO EXPLAIN, NOW USE THE PHRASE QUANTUM JUMP TO MEAN A BIG EVENT. WHEN
NON-SCIENTISTS START THROWING AROUND SCIENTIFIC TERMS WITHOUT UNDERSTANDING
THEM, FUNNY THINGS HAPPEN. DON'T GET ME STARTED ON THE HEISENBERG UNCERTAINTY
PRINCIPLE.

INCIDENTALLY, ALBERT EINSTEIN'S FATHER, HERMANN, WAS BORN IN THE WURTTEMBERG
VILLAGE OF BUCHAU, WHERE HIS FAMILY HAD LIVED FOR GENERATIONS. HERMANN MOVED 20
MILES FROM BUCHAU TO THE CITY OF ULM, WHERE ALBERT WAS BORN. MY GREAT-GREAT
GRANDFATHER, JOSEPH KOHN, WAS ALSO FROM BUCHAU AND HE HAD MANY EINSTEINS IN HIS
FAMILY TREE. I AM VERY PROUD OF THE EINSTEIN CONNECTION.

Wanger International Small Cap rose 30.27% in 2004. The Fund finished the year
ahead of the Citigroup EMI Global ex-US Index, up 29.27%. Wanger International
Small Cap also substantially outperformed the large-cap MSCI EAFE Index, up
20.25% in 2004. A weak U.S. dollar, particularly against the euro, aided
performance throughout the year.

The Fund's biggest percentage winners in 2004 came from very different
industries and regions of the world. Edgars Consolidated Stores, a South African
retailer first purchased in 2004, returned 151% for the year on strong earnings
growth. Another new 2004 purchase, Natura Cosmeticos, a manufacturer and direct
seller of Brazilian cosmetics, gained 139% for the year.

ComfortDelGro, a Singaporean transport company expanding into taxicab franchises
in China, was the third best annual performer, returning 107%. Within Europe,
Amplifon, an Italian manufacturer of hearing aids, surged 95%. Other winners
included Aalberts Industries, a Netherlands diversified industrial company,
which rose over 90%, and Tullow Oil, up 93%, an UK-based oil exploration company
benefiting from the rise in energy prices.

Technology-related stocks were among the leading detractors to portfolio
performance during the year. ASE Test, a Taiwanese tester of semiconductor
devices, was the Funds largest percentage loser, declining 55% on weak earnings.
Ngai Lik Industrial, a Hong Kong-based manufacturer of audio equipment, declined
37% as higher raw material costs squeezed margins. Another loser was Kappa
Create, a Japanese sushi chain operator. Rising over 50% from January to June,
the stock declined sharply in the second half when increased competition caused
reduced sales. The stock ended the year down 31%.

International small caps have outperformed large caps for a fifth year in a row
and valuations are now close to long-term average valuations relative to large
caps, whereas two years ago they traded at a moderate discount. Fortunately, our
international small-cap universe is comprised of over 4,400 potential investment
opportunities from which we need to extract but a few. With a dedicated team of
nine international analysts we feel we have the resources to sift through this
universe and still find attractive investment candidates for our shareholders.

INVESTMENTS IN FOREIGN SECURITIES HAVE SPECIAL RISKS, INCLUDING POLITICAL OR
ECONOMIC INSTABILITY, HIGHER COSTS, DIFFERENT REGULATIONS, ACCOUNTING STANDARDS,
TRADING PRACTICES AND LEVELS OF INFORMATION, AND CURRENCY EXCHANGE RATE
FLUCTUATIONS. SMALL-CAP STOCKS ARE OFTEN MORE VOLATILE AND LESS LIQUID THAN THE
STOCKS OF LARGER COMPANIES. SMALL COMPANIES MAY HAVE A SHORTER HISTORY OF
OPERATIONS THAN LARGER COMPANIES AND MAY HAVE A LESS DIVERSIFIED PRODUCT LINE,
MAKING THEM MORE SUSCEPTIBLE TO MARKET PRESSURE.

AS OF 12/31/04, THE FUND'S POSITIONS IN THE HOLDINGS MENTIONED WERE: EDGARS
CONSOLIDATED STORES, 0.9%; NATURA COSMETICOS, 1.0%; COMFORTDELGRO, 0.6%;
AMPLIFON, 1.5%; AALBERTS INDUSTRIES, 1.1%; TULLOW OIL, 0.8%; ASE TEST, 0.4%;
NGAI LIK INDUSTRIAL, 0.4%; KAPPA CREATE, 0.5%.

This graph compares the results of $10,000 invested in Wanger International
Small Cap on May 3,1995 (the date the Fund began operations) through December
31, 2004 with the Citigroup EMI Global ex-US. Dividends and capital gains are
reinvested. 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 $3 billion. 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.

PERFORMANCE NUMBERS REFLECT ALL FUND EXPENSES BUT DO NOT INCLUDE ANY INSURANCE
CHARGE IMPOSED BY YOUR INSURANCE COMPANY'S SEPARATE ACCOUNTS. IF PERFORMANCE
INCLUDED THE EFFECT OF THESE ADDITIONAL CHARGES, IT WOULD BE LOWER.

- --------------------------------------------------------------------------------
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 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. Securities for which quotations are not readily available and any
other assets are valued as determined in good faith by 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 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. 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. 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/Trust 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.

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.

FOREIGN CAPITAL GAINS TAXES

Realized gains in certain countries may be subject to foreign taxes at the fund
level, at rates ranging from 10%-30%. 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, 2004, permanent differences resulting
primarily from differing treatments for foreign currency transactions, foreign

      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 years ended December
31, 2004 and December 31, 2003 was as follows:

                             DECEMBER 31, 2004          DECEMBER 31, 2003

*   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 PFIC adjustments.

      Unrealized appreciation and depreciation at December 31, 2004, based on
cost of investments for federal income tax purposes, was:

Expired capital loss carryforwards, if any, are recorded as a reduction of
paid-in capital.

Capital loss carryforwards of $37,528,270 were utilized during the year ended
December 31, 2004 for the Fund.

4.  TRANSACTIONS WITH AFFILIATES

Columbia Wanger Asset Management, L.P., ("Columbia WAM") an indirect
wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a
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. Prior to April 1, 2004, Columbia was
a wholly-owned subsidiary of Fleet National Bank, which in turn was a
wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"). On April
1, 2004, Fleet was acquired by BOA.

      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                                 1.30%
    Next $150 million                                          1.20%
    In excess of $250 million                                  1.10%

For the year ended December 31, 2004, the Fund's effective investment advisory
fee rate was 1.17%.

      The investment advisory agreement also provides that 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 the average
daily net assets. There was no reimbursement for the year ended December 31,
2004.

      In accordance with the terms of the NYAG Settlement (as defined and
discussed further under Note 8 to these Financial Statements - "Legal
Proceedings"), Columbia WAM waived a portion of the fees payable under the
Fund's investment management agreement so that those fees are retained at the
following rates as a percent of average daily net assets: 1.150% - up to $100
million; 1.000% - $100 million to $250 million; 0.950% - $250 million and over.
The fee waiver was effective as of February 10, 2005 but applied as if it had
gone into effect on December 1, 2004. The financial statements, as of December
31, 2004, are not reflective of these changes.

      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, 2004, the Fund
paid $70,268 to trustees not affiliated with Columbia WAM. Effective April 2004,
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 on the Statement of Operations.

      Columbia Funds Distributor, Inc. ("CFDI"), an indirect wholly-owned
subsidiary of BOA, serves as the principal underwriter of the Trust and receives
no compensation for its services.

      Columbia Funds Services, Inc. (the "Transfer Agent"), an indirect
wholly-owned subsidiary of BOA, provides shareholder services to the Fund. For
such services, the Transfer Agent receives a fee, paid monthly, at the annual
rate of $28.00 per open account. The Transfer Agent also receives reimbursement
for certain out-of-pocket expenses. Effective February 1, 2004 the Transfer
Agent made the decision to waive the reimbursement for certain out-of-pocket
expenses. Prior to February 1, 2004, the Transfer Agent was entitled to receive
a flat rate charge based on the number of shareholder accounts and transactions.

      During the year ended December 31, 2004, 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 $11,599 and
$3,626,822, respectively.

8. LEGAL PROCEEDINGS

On March 15, 2004, Columbia Management Advisors, Inc. ("Columbia Management"),
the advisor to the Columbia Funds, and CFDI (collectively with Columbia
Management, "Columbia") the distributor of the shares of the Columbia Funds, the
Columbia Acorn Funds and the Wanger Advisors Trust Funds (collectively, "the
Columbia Family of Funds"), entered into agreements in principle with the staff
of the U.S. Securities and Exchange Commission ("SEC") and the Office of the New
York Attorney General ("NYAG") to resolve the proceedings brought in connection
with the SEC's and NYAG's investigations of frequent trading and market timing
in certain Columbia mutual funds. Columbia WAM, the advisor to the Columbia
Acorn Funds and the Wanger Advisors Trust Funds, was not a respondent in either
proceeding nor were any of its officers or directors.

      On February 9, 2005, Columbia entered into an Assurance of Discontinuance
(the "NYAG Settlement") with the NYAG and consented to the entry of a
cease-and-desist order by the SEC (the "SEC Order" and together, the
"Settlements"). The Settlements contain substantially the same terms and
conditions as outlined in the agreements in principle. Although none of the
Wanger Advisors Trust Funds is a party to the Settlement orders, under the terms
of the Settlements and in order for Columbia Management to continue to provide
administrative services to the Wanger Advisors Funds, the Board of Trustees of
the Wanger Advisors Trust Funds agreed to conform to certain governance
requirements, including the election of an independent board chair.

      Under the terms of the SEC Order, Columbia has agreed, among other things,
to: pay $70 million in disgorgement and $70 million in civil money penalties;
cease and desist from violations of the antifraud provisions and certain other
provisions of the federal securities laws; maintain certain compliance and
ethics oversight structures; retain an independent consultant to review
Columbia's applicable supervisory, compliance, control and other policies and
procedures; and retain an independent distribution consultant (see below). The
NYAG Settlement also, among other things, requires Columbia and its affiliates,
Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce
management fees paid by the Columbia Family of Funds, Nations Funds and other
related mutual funds collectively by $32 million per year for five years, for a
projected total of $160 million in management fee reductions based on net assets
as of March 15, 2004. Pursuant to the procedures set forth in the SEC Order, the
settlement amounts will be distributed in accordance with a distribution plan to
be developed by an independent distribution consultant, who is acceptable to the
SEC staff and the independent trustees of the funds. The distribution plan must
be based on a methodology developed in consultation with Columbia and the
independent trustees of the funds and not unacceptable to the staff of the SEC.
More specific information on the distribution plan will be communicated by
Columbia WAM and/or its affiliates at a later date.

      Columbia WAM, the Columbia Acorn Trust, another mutual fund family advised
by Columbia WAM, and the trustees of Columbia Acorn Trust are defendants in
several derivative and class action lawsuits that allege, in summary, defendants
permitted investors to engage in improper trading of shares of various funds in
violation of certain federal and state laws. All of these lawsuits have been
consolidated with similar suits in a Multi-District Litigation proceeding in
Baltimore, Maryland and consolidated class action and derivative complaints have
been filed.

      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
Fund's 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.

      Columbia WAM and the trustees of Columbia Acorn Trust are also defendants
in a lawsuit 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 other mutual funds to investors. The complaint alleges Columbia WAM
and the trustees of Columbia Acorn Trust breached certain common laws duties and
federal laws.

      On January 11, 2005 a putative class action lawsuit was filed in federal
district court in Massachusetts against, among others, the Trustees of the
Columbia Acorn Trust and Columbia WAM. The lawsuit alleges that defendants
violated common law duties to fund shareholders as well as sections of the
Investment Company Act of 1940, by failing to ensure that the Columbia Acorn
Trust funds and other affiliated funds participated in securities class action
settlements for which the funds were eligible. Specifically, plaintiffs allege
that defendants failed to submit Proof of Claims in connection with settlements
of securities class action lawsuits filed against companies in which the funds
held positions. The complaint seeks compensatory and punitive damages, and the
disgorgement of all fees paid to the Columbia WAM and affiliated advisers.

      The Columbia Acorn Trust and Columbia WAM intend to defend these suits
vigorously. The Columbia Acorn Trust does not believe that the pending actions
will have a material adverse effect on the financial statements of any Columbia
Acorn Fund, and Columbia WAM does not believe that the pending actions will have
a material adverse effect on its ability to perform under its contracts with the
Fund.

      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 Fund.

      In connection with the events described in detail above, various parties
have filed suit again certain funds, their Boards and/or BOA (and affiliated
entities). These suits are ongoing. Accordingly, an estimate of the financial
impact of this litigation on any fund, if any, cannot be currently made.

      For the year ended December 31, 2004, CMG has assumed $24,900 in
consulting services and legal fees incurred by the Fund in connection with these
matters.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Effective April 13, 2004, the audit committee of the Trust requested that Ernst
& Young LLP ("E&Y") resign as the auditors of the Fund. Also effective July 14,
2004, upon the recommendation of the audit committee, the Trust selected
PricewaterhouseCoopers LLP ("PWC") as independent registered public accounting
firm to audit the books and records of the Fund for its fiscal year ending
December 31, 2004. The cessation of the relationship with E&Y was based on the
impairment of E&Y's independence resulting from the consummation of the merger
of FleetBoston Financial Corporation and Bank of America Corporation and
accordingly, E&Y's ability to provide audit services to the Fund.

      E&Y's report on the financial statements of the Fund for the past two
years did not contain an adverse opinion or disclaimer of opinion, and was not
qualified or modified as to uncertainty, audit scope or accounting principles.
During the period E&Y was engaged, there were no disagreements with E&Y on any
matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedure which, if not resolved to E&Y's satisfaction, would
have caused it to make reference to that matter in connection with its 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, 2004, the results of its operations, the changes in its net
assets and the financial highlights for the year 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 audit. 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, 2004 by
correspondence with the custodian and brokers, provides a reasonable basis for
our opinion. The statement of changes in net assets for the year ended December
31, 2003 and 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.

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 continuing costs, which generally
include investment advisory, Rule 12b-1 fees, and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

ANALYZING YOUR FUND'S EXPENSES

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.

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
366.

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 12/31/04.

COMPARE WITH OTHER FUNDS

Since all mutual fund companies 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.

[LOGO ] THE MIRACLE YEAR

RALPH WANGER
FOUNDER, ADVISOR AND TRUSTEE
COLUMBIA WANGER ASSET MANAGEMENT, L.P.

1905 was a year of surprises. The first surprise was the victory of the Japanese
over the Russians in the Russo-Japanese War. In May 1905, the untested Japanese
Navy annihilated the Russian fleet at Tsushima. This was the first time a
non-white country had beaten the main force of a European colonial power. The
second unexpected event was in physics. 2005 will be celebrated as the
centennial of Albert Einstein's "Miracle Year."

The journal, ANNALEN DER PHYSIK, volume 17, published three articles in
September 1905 all written by Einstein, an obscure clerk in the Swiss patent
office in Bern. He had an undergraduate degree in physics but no Ph.D (it was
granted a year later). Each of the articles were on a different subject and each
one revolutionized its branch of physics. Einstein's papers created 20th century
physics almost single-handedly.

ATOMS

In 1905 there were different theories about the structure of matter. If you take
a glass of water and pour nine-tenths of it out, you still have a glass with
water in it. What happens if you repeat this process of throwing out 90% of the
water in the glass? After you repeat the process a few more times, you have such
a small amount of water that you can only see it under a microscope, and in a
few more steps the water drop will be too small to be seen even under the
microscope. Can you continue the boring job of splitting water forever or do you
finally get to a point where it isn't water anymore? Of course we know the
answer: Once you get down to a single molecule of water you can't split it and
still say that you have water left. Many leading scientists did not accept the
atomic theory in 1905. Einstein looked at the process called Brownian Motion in
which a grain of pollen or other small object moves around in a random way. (The
same mathematical process makes stock prices jiggle.) He deduced that this
motion was caused by billions of atoms bumping into the pollen grain in an
irregular pattern. He was even able to calculate the size of the atoms involved,
thus proving that atoms really existed.

PHOTONS

In 1905 there was still a basic debate about the nature of light. The greatest
achievement of 19th century physics was Maxwell's set of partial differential
equations governing electromagnetic fields, including light. Maxwell's equations
required that light be a wave. The great Max Planck had introduced the idea of a
quantum of energy in 1900 to get an equation that tracked the spectrum of heat
radiation, but most scientists doubted that a light quantum was "real." Heinrich
Hertz, Philip Lenard and others showed that when a beam of ultraviolet light
shines on a piece of metal you produce an electrical current in the metal. There
was no way to explain the photoelectric effect according to the Maxwell wave
theory of light. The second paper Einstein wrote dealt with the problem of the
photoelectric effect. If you cut the amount of energy in a beam of light by 90%
and keep reducing it, you still have a beam of light. If you keep slicing the
amount of light, does the beam of light keep getting smaller and smaller forever
or do you get down to an "atom" of light that can't be split further? Einstein
proved that there was a tiny amount of light that could not be further divided.
The least amount of light that exists is a single photon (or quantum) of light.
1 The photoelectric effect is explained by photons acting as particles, not as a
wave.

Einstein's discovery of the photon had a number of interesting effects. First,
it led to the development of quantum mechanics and thus to most of 20th century
physics. Second, it won Einstein his only Nobel Prize. Third, it uncovered a
paradox that still puzzles students, the duality of light. If you run an
experiment to show that light is a wave, you can prove it's a wave. If you run
an experiment to show that it's a particle, you can prove it's a particle. This
duality principle contradicts common sense but when you study science you have
to get used to it. The fourth effect was that it made Lenard a life-long enemy
of Einstein. Philip Lenard, who received the Nobel Prize in 1905 for his own
work on cathode rays, was close to the solution but Einstein ended up getting
the credit. Lenard became an unrelenting foe of Einstein, and influenced the
Nobel committee's decision not to give Einstein the prize for his theory of
relativity. Later on, Lenard became an ardent Nazi.

RELATIVITY

In 1905, there was also a debate in scientific circles about speed. If you were
in a really powerful rocket ship in space, and you pushed the throttle forward,
you would speed up. If you kept on increasing the power, would you go ever
faster, or was there an absolute speed limit in the universe that you could not
exceed?

- --------------------------------------------------------------------------------

The third paper became the best known, Einstein's special theory of relativity.
It explained that there was a cosmic speed limit, the speed of light. Very odd
things happen when your rocket ship is moving close to the speed of light. Time
slows down and you get shorter, under the Lorentz contraction equation, giving
rise to the limerick:

A sexy young techie named Fisk, Had a motion exceedingly brisk. So fast was his
action The Lorentz contraction Shortened his rod to a disk.

In a very brief paper published later in 1905, Einstein added in a note that his
theory of relativity implied the equation E=mc2. That solved the paradox of
radioactivity; Mme Curie's radium was producing much more energy then could be
explained by 19th century physics. Einstein showed that radioactive energy was
caused by turning a small amount of mass into a lot of energy.

So we had this technical journal containing three papers written by a man
unknown in science, a non-Ph.D, a non-academic, writing on a German-dominated
field with all the fussiness about rank and reputation that you would expect.
Would anyone care? Einstein did not receive any communication from any
physicists for the first couple months after he published, but in early 1906 Max
Planck read and understood the papers. He wrote to Einstein and sent his
assistant, another important physicist, Max von Laue, to visit Einstein in Bern.
Planck's subsequent endorsement made Einstein acceptable to the community of
physicists, and his papers became required study for all physicists, as they
remain.

The compelling human question: How the heck did Einstein do it? How could one
human being produce three revolutionary papers in one year, on three different
subjects, while carrying a full-time job at the patent office to boot? We can
admire but not explain. The "Miracle Year" commemorates one of the greatest
feats of the human mind ever.

1 PLANCK AND EINSTEIN HAD DISCOVERED THE QUANTUM JUMP, WHICH WAS THE SMALLEST
THING THAT COULD POSSIBLY EXIST IN THE UNIVERSE. MODERN WRITERS, FOR REASONS
DIFFICULT TO EXPLAIN, NOW USE THE PHRASE QUANTUM JUMP TO MEAN A BIG EVENT. WHEN
NON-SCIENTISTS START THROWING AROUND SCIENTIFIC TERMS WITHOUT UNDERSTANDING
THEM, FUNNY THINGS HAPPEN. DON'T GET ME STARTED ON THE HEISENBERG UNCERTAINTY
PRINCIPLE.

INCIDENTALLY, ALBERT EINSTEIN'S FATHER, HERMANN, WAS BORN IN THE WURTTEMBERG
VILLAGE OF BUCHAU, WHERE HIS FAMILY HAD LIVED FOR GENERATIONS. HERMANN MOVED 20
MILES FROM BUCHAU TO THE CITY OF ULM, WHERE ALBERT WAS BORN. MY GREAT-GREAT
GRANDFATHER, JOSEPH KOHN, WAS ALSO FROM BUCHAU AND HE HAD MANY EINSTEINS IN HIS
FAMILY TREE. I AM VERY PROUD OF THE EINSTEIN CONNECTION.

[LOGO ] PERFORMANCE REVIEW WANGER SELECT*

Photo of  BEN ANDREWS

BEN ANDREWS
PORTFOLIO MANAGER

It was a good year for Wanger Select. The Fund gained 19.31% during 2004,
outperforming the S&P MidCap 400's 16.48% return and the S&P 500's 10.88% gain.

McAfee, ITT Educational Services and Abercrombie & Fitch all did well for the
Fund for the annual period. McAfee was up 83% for the 12 months while ITT
Educational Services increased 65%. Together these two stocks made up over 6% of
the Fund's return for the year. Abercrombie & Fitch, up an impressive 91% in the
year, was another big contributor to Fund performance.

On the downside, Skillsoft cost the Fund some performance as the stock slid due
to continued pricing pressure from its largest competitor, Netg. Skillsoft was
down 29% for the 12 months. The largest detractors to performance, however, were
Synopsys, down 42%, and Interpublic Group, down 32%. We are evaluating whether
or not Synopsys has turn around potential. Interpublic Group was sold in the
fourth quarter.

Also during the fourth quarter, Oracle purchased one of the Fund's holdings,
PeopleSoft, after a lengthy and much publicized takeover battle. During the
17-month negotiation process for PeopleSoft, its board of directors received a
lot of bad press for not having the shareholders' best interests in mind. Our
firm's due diligence refuted this and we backed the board. In the end, the
board's moves did put its customer and shareholder interests first when trying
to negotiate with a very adversarial suitor. We received the cash proceeds from
the PeopleSoft transaction two days before the end of the year.

We also added six new names to the portfolio during the final three months of
the year while deleting one (PeopleSoft). New ideas include an investment in the
cable industry with UnitedGlobalCom and Liberty Media International. Both stocks
focus on serving foreign markets. The Fund also purchased IAC/InterActive, one
of the five big Internet companies, as its stock price reached a two-year low.
FMC Technologies was added as we believe offshore deep-water oil drilling will
increase over the next several years. The Fund also purchased Aspect
Communications and AnswerThink Consulting.

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 12/31/04, the Fund's positions in the holdings mentioned were: McAfee,
7.4%; ITT Educational Services, 5.4%; Abercrombie & Fitch, 3.6%; Skillsoft,
4.0%; Netg, 0.0%; Synopsys, 1.5%; Interpublic Group, 0.0%; Oracle, 0.0%;
PeopleSoft, 0.0%; UnitedGlobalCom, 0.9%; Liberty Media International, 0.9%;
IAC/InterActive, 1.6%; FMC Technologies, 0.9%; Aspect Communications, 0.1%;
AnswerThink Consulting, 0.2%.

                                               Wanger Select  2004 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 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. Securities for which quotations are not readily available and any
other assets are valued as determined in good faith by 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. 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. 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 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, 2004, permanent differences resulting
primarily from differing treatments for net operating losses 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
   -------------------   --------------------   --------
        $311,671              $(311,669)          $(2)

      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 years ended December
31, 2004 and December 31, 2003 was as follows:

                              DECEMBER 31, 2004  DECEMBER 31, 2003
                              -----------------  -----------------
Distributions paid from:
  Ordinary Income                $     --             $  --
  Long-Term Capital Gain           56,308                --

NOTES TO FINANCIAL STATEMENTS

      As of December 31, 2004, the components of distributable earnings on a tax
basis were as follows:

   UNDISTRIBUTED       UNDISTRIBUTED
     ORDINARY            LONG-TERM      NET UNREALIZED

     $550,044            $5,223,340       $17,580,317

*     The differences between book-basis and tax-basis net unrealized
      appreciation/depreciation are primarily due to deferral of losses from
      wash sales.

      Unrealized appreciation and depreciation at December 31, 2004, based on
cost of investments for federal income tax purposes, was:

                                             NET

4.    TRANSACTIONS WITH AFFILIATES

Columbia Wanger Asset Management, L.P., ("Columbia WAM") an indirect
wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a
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. Prior to April 1, 2004,
Columbia was a wholly-owned subsidiary of Fleet National Bank, which in turn was
a wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"). On
April 1, 2004, Fleet was acquired by BOA.

      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.

      The investment advisory agreement also provides that 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,
2004.

      In accordance with the terms of the NYAG Settlement (as defined and
discussed further under Note 8 to these financial statements - "Legal
Proceedings"), Columbia WAM waived a portion of the fees payable under the
Fund's investment management agreement so that those fees are retained at 0.850%
on average daily net assets. The fee waiver was effective as of February 10,
2005 but applied as if it had gone into effect on December 1, 2004. The
financial statements, as of December 31, 2004, are not reflective of these
changes.

      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. The Fund paid $10,118 to trustees not affiliated
with Columbia WAM for the year ended December 31, 2004. Effective April 2004,
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 on the Statement of Operations.

      Columbia Funds Distributor, Inc. ("CFDI"), an indirect wholly-owned
subsidiary of BOA, serves as the principal underwriter of the Trust and receives
no compensation for its services.

      Columbia Funds Services, Inc. (the "Transfer Agent"), an indirect
wholly-owned subsidiary of BOA, provides shareholder services to the Fund. For
such services, the Transfer Agent receives a fee, paid monthly, at the annual
rate of $28.00 per open account. The Transfer Agent also receives reimbursement
for certain out-of-pocket expenses. Effective February 1, 2004 the Transfer
Agent made the decision to waive the reimbursement for certain out-of-pocket
expenses. Prior to February 1, 2004, the Transfer Agent was entitled to receive
a flat rate charge based on the number of shareholder accounts and transactions.

      During the year ended December 31, 2004, 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 $64,400 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 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

8.  LEGAL PROCEEDINGS

On March 15, 2004, Columbia Management Advisors, Inc. ("Columbia Management"),
the advisor to the Columbia Funds, and CFDI (collectively with Columbia
Management, "Columbia") the distributor of the shares of the Columbia Funds, the
Columbia Acorn Funds and the Wanger Advisors Trust Funds (collectively, "the
Columbia Family of Funds"), entered into agreements in principle with the staff
of the U.S. Securities and Exchange Commission ("SEC") and the Office of the New
York Attorney General ("NYAG") to resolve the proceedings brought in connection
with the SEC's and NYAG's investigations of frequent trading and market timing
in certain Columbia mutual funds. Columbia WAM, the advisor to the Columbia
Acorn Funds and the Wanger Advisors Trust Funds, was not a respondent in either
proceeding nor were any of its officers or directors.

      On February 9, 2005, Columbia entered into an Assurance of Discontinuance
(the "NYAG Settlement") with the NYAG and consented to the entry of a
cease-and-desist order by the SEC (the "SEC Order" and together, the
"Settlements"). The Settlements contain substantially the same terms and
conditions as outlined in the agreements in principle. Although none of the
Wanger Advisors Trust Funds is a party to the Settlement orders, under the terms
of the Settlements and in order for Columbia Management to continue to provide
administrative services to the Wanger Advisors Funds, the Board of Trustees of
the Wanger Advisors Trust Funds agreed to conform to certain governance
requirements, including the election of an independent board chair.

      Under the terms of the SEC Order, Columbia has agreed, among other things,
to: pay $70 million in disgorgement and $70 million in civil money penalties;
cease and desist from violations of the antifraud provisions and certain other
provisions of the federal securities laws; maintain certain compliance and
ethics oversight structures; retain an independent consultant to review
Columbia's applicable supervisory, compliance, control and other

NOTES TO FINANCIAL STATEMENTS

policies and procedures; and retain an independent distribution consultant (see
below). The NYAG Settlement also, among other things, requires Columbia and its
affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC
to reduce management fees paid by the Columbia Family of Funds, Nations Funds
and other related mutual funds collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions based
on net assets as of March 15, 2004. Pursuant to the procedures set forth in the
SEC Order, the settlement amounts will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the independent trustees of the funds. The
distribution plan must be based on a methodology developed in consultation with
Columbia and the independent trustees of the funds and not unacceptable to the
staff of the SEC. More specific information on the distribution plan will be
communicated by Columbia WAM and/or its affiliates at a later date.

      Columbia WAM, the Columbia Acorn Trust, another mutual fund family advised
by Columbia WAM, and the trustees of Columbia Acorn Trust are defendants in
several derivative and class action lawsuits that allege, in summary, defendants
permitted investors to engage in improper trading of shares of various funds in
violation of certain federal and state laws. All of these lawsuits have been
consolidated with similar suits in a Multi-District Litigation proceeding in
Baltimore, Maryland and consolidated class action and derivative complaints have
been filed.

      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
Fund's 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.

      Columbia WAM and the trustees of Columbia Acorn Trust are also defendants
in a lawsuit 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 other mutual funds to investors. The complaint alleges Columbia WAM
and the trustees of Columbia Acorn Trust breached certain common laws duties and
federal laws.

      On January 11, 2005 a putative class action lawsuit was filed in federal
district court in Massachusetts against, among others, the Trustees of the
Columbia Acorn Trust and Columbia WAM. The lawsuit alleges that defendants
violated common law duties to fund shareholders as well as sections of the
Investment Company Act of 1940, by failing to ensure that the Columbia Acorn
Trust funds and other affiliated funds participated in securities class action
settlements for which the funds were eligible. Specifically, plaintiffs allege
that defendants failed to submit Proof of Claims in connection with settlements
of securities class action lawsuits filed against companies in which the funds
held positions. The complaint seeks compensatory and punitive damages, and the
disgorgement of all fees paid to the Columbia WAM and affiliated advisers.

      The Columbia Acorn Trust and Columbia WAM intend to defend these suits
vigorously. The Columbia Acorn Trust does not believe that the pending actions
will have a material adverse effect on the financial statements of any Columbia
Acorn Fund, and Columbia WAM does not believe that the pending actions will have
a material adverse effect on its ability to perform under its contracts with the
Funds.

      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 again certain funds, their Boards and/or BOA (and affiliated
entities). These suits are ongoing. Accordingly, an estimate of the financial
impact of this litigation on any fund, if any, cannot be currently made.

      For the year ended December 31, 2004, CMG has assumed $3,354 in consulting
services and legal fees incurred by the Fund in connection with these matters.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Effective April 13, 2004, the audit committee of the Trust requested that Ernst
& Young LLP ("E&Y") resign as the auditors of the Fund. Also effective July 14,
2004, upon the recommendation of the audit committee, the Trust selected
PricewaterhouseCoopers LLP ("PWC") as independent registered public accounting
firm to audit the books and records of the Fund for its fiscal year ending
December 31, 2004. The cessation of the relationship with E&Y was based on the
impairment of E&Y's independence resulting from the consummation of the merger
of FleetBoston Financial Corporation and Bank of America Corporation and
accordingly, E&Y's ability to provide audit services to the Fund.

   E&Y's report on the financial statements of the Fund for the past two years
did not contain an adverse opinion or disclaimer of opinion, and was not
qualified or modified as to uncertainty, audit scope or accounting principles.
During the period E&Y was engaged, there were no disagreements with E&Y on any
matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedure which, if not resolved to E&Y's satisfaction, would
have caused it to make reference to that matter in connection with its 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,
2004, the results of its operations, the changes in its net assets and the
financial highlights for the year 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 audit. 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, 2004 by
correspondence with the custodian and brokers, provides a reasonable basis for
our opinion. The statement of changes in net assets for the year ended December
31, 2003 and 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.

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 continuing costs, which generally
include investment advisory, Rule 12b-1 fees, and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

ANALYZING YOUR FUND'S EXPENSES

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.

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
366.

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 12/31/04.

COMPARE WITH OTHER FUNDS

Since all mutual fund companies 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.

[LOGO] THE MIRACLE YEAR

Photo of RALPH WANGER

RALPH WANGER
FOUNDER, ADVISOR AND TRUSTEE
COLUMBIA WANGER ASSET MANAGEMENT, L.P.

1905 was a year of surprises. The first surprise was the victory of the Japanese
over the Russians in the Russo-Japanese War. In May 1905, the untested Japanese
Navy annihilated the Russian fleet at Tsushima. This was the first time a
non-white country had beaten the main force of a European colonial power. The
second unexpected event was in physics. 2005 will be celebrated as the
centennial of Albert Einstein's "Miracle Year."

The journal, ANNALEN DER PHYSIK, volume 17, published three articles in
September 1905 all written by Einstein, an obscure clerk in the Swiss patent
office in Bern. He had an undergraduate degree in physics but no Ph.D (it was
granted a year later). Each of the articles were on a different subject and each
one revolutionized its branch of physics. Einstein's papers created 20th century
physics almost single-handedly.

ATOMS

In 1905 there were different theories about the structure of matter. If you take
a glass of water and pour nine-tenths of it out, you still have a glass with
water in it. What happens if you repeat this process of throwing out 90% of the
water in the glass? After you repeat the process a few more times, you have such
a small amount of water that you can only see it under a microscope, and in a
few more steps the water drop will be too small to be seen even under the
microscope. Can you continue the boring job of splitting water forever or do you
finally get to a point where it isn't water anymore? Of course we know the
answer: Once you get down to a single molecule of water you can't split it and
still say that you have water left. Many leading scientists did not accept the
atomic theory in 1905. Einstein looked at the process called Brownian Motion in
which a grain of pollen or other small object moves around in a random way. (The
same mathematical process makes stock prices jiggle.) He deduced that this
motion was caused by billions of atoms bumping into the pollen grain in an
irregular pattern. He was even able to calculate the size of the atoms involved,
thus proving that atoms really existed.

PHOTONS

In 1905 there was still a basic debate about the nature of light. The greatest
achievement of 19th century physics was Maxwell's set of partial differential
equations governing electromagnetic fields, including light. Maxwell's equations
required that light be a wave. The great Max Planck had introduced the idea of a
quantum of energy in 1900 to get an equation that tracked the spectrum of heat
radiation, but most scientists doubted that a light quantum was "real." Heinrich
Hertz, Philip Lenard and others showed that when a beam of ultraviolet light
shines on a piece of metal you produce an electrical current in the metal. There
was no way to explain the photoelectric effect according to the Maxwell wave
theory of light. The second paper Einstein wrote dealt with the problem of the
photoelectric effect. If you cut the amount of energy in a beam of light by 90%
and keep reducing it, you still have a beam of light. If you keep slicing the
amount of light, does the beam of light keep getting smaller and smaller forever
or do you get down to an "atom" of light that can't be split further? Einstein
proved that there was a tiny amount of light that could not be further divided.
The least amount of light that exists is a single photon (or quantum) of light.
1 The photoelectric effect is explained by photons acting as particles, not as a
wave.

Einstein's discovery of the photon had a number of interesting effects. First,
it led to the development of quantum mechanics and thus to most of 20th century
physics. Second, it won Einstein his only Nobel Prize. Third, it uncovered a
paradox that still puzzles students, the duality of light. If you run an
experiment to show that light is a wave, you can prove it's a wave. If you run
an experiment to show that it's a particle, you can prove it's a particle. This
duality principle contradicts common sense but when you study science you have
to get used to it. The fourth effect was that it made Lenard a life-long enemy
of Einstein. Philip Lenard, who received the Nobel Prize in 1905 for his own
work on cathode rays, was close to the solution but Einstein ended up getting
the credit. Lenard became an unrelenting foe of Einstein, and influenced the
Nobel committee's decision not to give Einstein the prize for his theory of
relativity. Later on, Lenard became an ardent Nazi.

RELATIVITY

In 1905, there was also a debate in scientific circles about speed. If you were
in a really powerful rocket ship in space, and you pushed the throttle forward,
you would speed up. If you kept on increasing the power, would you go ever
faster, or was there an absolute speed limit in the universe that you could not
exceed?

                                        2




                                 Wanger International Select  2004 Annual Report
- --------------------------------------------------------------------------------

The third paper became the best known, Einstein's special theory of relativity.
It explained that there was a cosmic speed limit, the speed of light. Very odd
things happen when your rocket ship is moving close to the speed of light. Time
slows down and you get shorter, under the Lorentz contraction equation, giving
rise to the limerick:

A sexy young techie named Fisk, Had a motion exceedingly brisk. So fast was his
action The Lorentz contraction Shortened his rod to a disk.

In a very brief paper published later in 1905, Einstein added in a note that his
theory of relativity implied the equation E=mc 2. That solved the paradox of
radioactivity; Mme Curie's radium was producing much more energy then could be
explained by 19th century physics. Einstein showed that radioactive energy was
caused by turning a small amount of mass into a lot of energy.

So we had this technical journal containing three papers written by a man
unknown in science, a non-Ph.D, a non-academic, writing on a German-dominated
field with all the fussiness about rank and reputation that you would expect.
Would anyone care? Einstein did not receive any communication from any
physicists for the first couple months after he published, but in early 1906 Max
Planck read and understood the papers. He wrote to Einstein and sent his
assistant, another important physicist, Max von Laue, to visit Einstein in Bern.
Planck's subsequent endorsement made Einstein acceptable to the community of
physicists, and his papers became required study for all physicists, as they
remain.

The compelling human question: How the heck did Einstein do it? How could one
human being produce three revolutionary papers in one year, on three different
subjects, while carrying a full-time job at the patent office to boot? We can
admire but not explain. The "Miracle Year" commemorates one of the greatest
feats of the human mind ever.

1 PLANCK AND EINSTEIN HAD DISCOVERED THE QUANTUM JUMP, WHICH WAS THE SMALLEST
THING THAT COULD POSSIBLY EXIST IN THE UNIVERSE. MODERN WRITERS, FOR REASONS
DIFFICULT TO EXPLAIN, NOW USE THE PHRASE QUANTUM JUMP TO MEAN A BIG EVENT. WHEN
NON-SCIENTISTS START THROWING AROUND SCIENTIFIC TERMS WITHOUT UNDERSTANDING
THEM, FUNNY THINGS HAPPEN. DON'T GET ME STARTED ON THE HEISENBERG UNCERTAINTY
PRINCIPLE.

INCIDENTALLY, ALBERT EINSTEIN'S FATHER, HERMANN, WAS BORN IN THE WURTTEMBERG
VILLAGE OF BUCHAU, WHERE HIS FAMILY HAD LIVED FOR GENERATIONS. HERMANN MOVED 20
MILES FROM BUCHAU TO THE CITY OF ULM, WHERE ALBERT WAS BORN. MY GREAT-GREAT
GRANDFATHER, JOSEPH KOHN, WAS ALSO FROM BUCHAU AND HE HAD MANY EINSTEINS IN HIS
FAMILY TREE. I AM VERY PROUD OF THE EINSTEIN CONNECTION.

International markets surged in 2004. Wanger International Select ended the year
up 24.34%, a solid return but behind the 25.22% return for the Citigroup World
ex-US Cap Range $2-10B Index. The relative underperformance was due in large
part to holding some cash as the markets rallied in the fourth quarter of the
year. We opted to take profits in a number of positions to look for better
values elsewhere. We believe that the Fund is well positioned for future growth.

Letting our winners run was a successful strategy this past year. Anglo Irish
Bank was the Fund's largest contributor to performance. The stock finished the
year up 56% and is the Fund's largest position. Other significant winners for
the Fund included large holdings with great franchises. Neopost, a maker of
franking machines in France and the Fund's second largest position, had another
strong year, up 58%. Tenaris, a maker of steel pipes for the oil and gas
industry, jumped 49%. Lion Nathan, the major beer brewer and distributor in
Australia and New Zealand, rose 55% and Daito Trust Construction, a major
apartment builder and manager in Japan, finished the year up 62%.

Several stocks in the portfolio reduced the Fund's gains. Topping the list of
poor performers in the Fund this year was Sugi Pharmacy, a drugstore chain in
Japan. Shares were down 13% as the company reported higher costs than expected
during its expansion program. Funai Electric, a maker of consumer electronic
products in Japan, was down 13% as the retail environment in the United States
was weaker than expected. Other weak performers included Venture, an electronic
manufacturing services company in Singapore, down 15%, and Compass Group, a
catering services provider in the UK, which fell 29% on an earnings downgrade
driven by a weak dollar and issues with a supplier.

Share prices have risen strongly in the past two years. While stocks are not as
cheap as they once were, we continue to find well-run companies with good
strategies and strong balance sheets that we believe will be good investments.

MID-CAP STOCKS TEND TO BE MORE VOLATILE AND MAY BE 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.

As of 12/31/04, the Fund's positions in the holdings mentioned were: Anglo Irish
Bank, 6.3%; Neopost, 4.2%; Tenaris, 2.1%; Lion Nathan, 3.8%; Daito Trust
Construction, 3.4%; Sugi Pharmacy, 1.9%; Funai Electric, 2.4%; Venture, 0.9%;
Compass Group, 2.0%.

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, 2004, to the 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. 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.

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.

                                 Wanger International Select  2004 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 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. Securities for which quotations are not readily available and any
other assets are valued as determined in good faith by 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.

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. 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. 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.

FOREIGN CAPITAL GAINS TAXES

Realized gains in certain countries may be subject to foreign taxes at the fund
level, at rates ranging from 10%-30%. 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, 2004, permanent differences resulting
primarily from differing treatments for foreign currency transactions and
passive foreign investment company adjustments ("PFICs") were identified and
reclassified among the components of the Fund's net assets as follows:

       UNDISTRIBUTED            ACCUMULATED      PAID IN
    NET INVESTMENT INCOME    NET REALIZED LOSS   CAPITAL
    ---------------------    -----------------   -------
        $96,504                  $(96,502)         $(2)

    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 years ended December 31,
2004 and December 31, 2003 was as follows:

                                       12

  Ordinary Income                       $87,061                $50,019

      As of December 31, 2004, the components of distributable earnings on a tax
basis were as follows:

    UNDISTRIBUTED          UNDISTRIBUTED
      ORDINARY               LONG-TERM           NET UNREALIZED

       $765,798                $--                 $9,134,912

*     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.

      Unrealized appreciation and depreciation at December 31, 2004, based on
cost of investments for federal income tax purposes, was:

                               NET
     UNREALIZED            UNREALIZED       UNREALIZED

     $9,546,892            $(413,318)       $9,133,574

    The following capital loss carryforwards, determined as of December 31,
2004, are 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                   $ 3,592,626
    2011                       982,004
                        --------------
    Total                  $ 4,574,630

      Expired capital loss carryforwards, if any, are recorded as a reduction of
paid-in capital.

      Capital loss carryforwards of $3,213,886 were utilized during the year
ended December 31, 2004 for the Fund.

4.    TRANSACTIONS WITH AFFILIATES

Columbia Wanger Asset Management, L.P., ("Columbia WAM") an indirect
wholly-owned subsidiary of Columbia Management Group, Inc., which in turn is a
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. Prior to April 1, 2004, Columbia was
a wholly-owned subsidiary of Fleet National Bank, which in turn was a
wholly-owned subsidiary of FleetBoston Financial Corporation ("Fleet"). On April
1, 2004, Fleet was acquired by BOA.

      Under the Fund's investment management agreement, fees are accrued daily
and paid monthly to Columbia WAM at the annual percentage of 1.00% of average
daily net assets.

      The investment advisory agreement also provides that Columbia WAM will
reimburse the Fund to the extent that ordinary operating expenses (computed
based on net custodian fees) exceed an annual rate of 1.45% of average daily net
assets. There was no reimbursement for the year ended December 31, 2004.

      In accordance with the terms of the NYAG Settlement (as defined and
discussed further under Note 8 to these Financial Statements - "Legal
Proceedings"), Columbia WAM waived a portion of the fees payable under the
Fund's investment management agreement so that those fees are retained at 0.990%
on average daily net assets. The fee waiver was effective as of February 10,
2005 but applied as if it had gone into effect on December 1, 2004. The
financial statements, as of December 31, 2004, are not reflective of these
changes.

      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. The Fund paid $6,323 to trustees not affiliated
with Columbia WAM for the year ended December 31, 2004. Effective April 2004,
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 on the Statement of Operations.

      Columbia Funds Distributor, Inc. ("CFDI"), an indirect wholly-owned
subsidiary of BOA, serves as the principal underwriter of the Trust and receives
no compensation for its services.

      Columbia Funds Services, Inc. (the "Transfer Agent"), an indirect
wholly-owned subsidiary of BOA, provides shareholder services to the Fund. For
such services, the Transfer Agent receives a fee, paid monthly, at the annual
rate of $28.00 per open account. The Transfer Agent also receives reimbursement
for certain out-of-pocket expenses. Effective February 1, 2004 the Transfer
Agent made the decision to waive the reimbursement for certain out-of-pocket
expenses. Prior to February 1, 2004, the Transfer Agent was entitled to receive
a flat rate charge based on the number of shareholder accounts and transactions.

      During the year ended December 31, 2004, 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 $405,544 and
$1,192,967, 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, 2004.

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:

8.    LEGAL PROCEEDINGS

On March 15, 2004, Columbia Management Advisors, Inc. ("Columbia Management"),

NOTES TO FINANCIAL STATEMENTS

in principle with the staff of the U.S. Securities and Exchange Commission
("SEC") and the Office of the New York Attorney General ("NYAG") to resolve the
proceedings brought in connection with the SEC's and NYAG's investigations of
frequent trading and market timing in certain Columbia mutual funds. Columbia
WAM, the advisor to the Columbia Acorn Funds and the Wanger Advisors Trust
Funds, was not a respondent in either proceeding nor were any of its officers or
directors.

      On February 9, 2005, Columbia entered into an Assurance of Discontinuance
(the "NYAG Settlement") with the NYAG and consented to the entry of a
cease-and-desist order by the SEC (the "SEC Order" and together, the
"Settlements"). The Settlements contain substantially the same terms and
conditions as outlined in the agreements in principle. Although none of the
Wanger Advisors Trust Funds is a party to the Settlement orders, under the terms
of the Settlements and in order for Columbia Management to continue to provide
administrative services to the Wanger Advisors Funds, the Board of Trustees of
the Wanger Advisors Trust Funds agreed to conform to certain governance
requirements, including the election of an independent board chair.

      Under the terms of the SEC Order, Columbia has agreed, among other things,
to: pay $70 million in disgorgement and $70 million in civil money penalties;
cease and desist from violations of the antifraud provisions and certain other
provisions of the federal securities laws; maintain certain compliance and
ethics oversight structures; retain an independent consultant to review
Columbia's applicable supervisory, compliance, control and other policies and
procedures; and retain an independent distribution consultant (see below). The
NYAG Settlement also, among other things, requires Columbia and its affiliates,
Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce
management fees paid by the Columbia Family of Funds, Nations Funds and other
related mutual funds collectively by $32 million per year for five years, for a
projected total of $160 million in management fee reductions based on net assets
as of March 15, 2004. Pursuant to the procedures set forth in the SEC Order, the
settlement amounts will be distributed in accordance with a distribution plan to
be developed by an independent distribution consultant, who is acceptable to the
SEC staff and the independent trustees of the funds. The distribution plan must
be based on a methodology developed in consultation with Columbia and the
independent trustees of the funds and not unacceptable to the staff of the SEC.
More specific information on the distribution plan will be communicated by
Columbia WAM and/or its affiliates at a later date.

      Columbia WAM, the Columbia Acorn Trust, another mutual fund family advised
by Columbia WAM and the trustees of Columbia Acorn Trust, are defendants in
several derivative and class action lawsuits that allege, in summary, defendants
permitted investors to engage in improper trading of shares of various funds in
violation of certain federal and state laws. All of these lawsuits have been
consolidated with similar suits in a Multi-District Litigation proceeding in
Baltimore, Maryland and consolidated class action and derivative complaints have
been filed.

      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
Fund's 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.

      Columbia WAM and the trustees of Columbia Acorn Trust are also defendants
in a lawsuit 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 other mutual funds to investors. The complaint alleges Columbia WAM
and the trustees of Columbia Acorn Trust breached certain common laws duties and
federal laws.

      On January 11, 2005 a putative class action lawsuit was filed in federal
district court in Massachusetts against, among others, the Trustees of the
Columbia Acorn Trust and Columbia WAM. The lawsuit alleges that defendants
violated common law duties to fund shareholders as well as sections of the
Investment Company Act of 1940, by failing to ensure that the Columbia Acorn
Trust funds and other affiliated funds participated in securities class action
settlements for which the funds were eligible. Specifically, plaintiffs allege
that defendants failed to submit Proof of Claims in connection with settlements
of securities class action lawsuits filed against companies in which the funds
held positions. The complaint seeks compensatory and punitive damages, and the
disgorgement of all fees paid to the Columbia WAM and affiliated advisers.

      The Columbia Acorn Trust and Columbia WAM intend to defend these suits
vigorously. The Columbia Acorn Trust does not believe that the pending actions
will have a material adverse effect on the financial statements of any Columbia
Acorn Fund, and Columbia WAM does not believe that the pending actions will have
a material adverse effect on its ability to perform under its contracts with the
Funds.

      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 Fund.

      In connection with the events described in detail above, various parties
have filed suit again certain funds, their Boards and/or BOA (and affiliated
entities). These suits are ongoing. Accordingly, an estimate of the financial
impact of this litigation on any fund, if any, cannot be currently made.

      For the year ended December 31, 2004, CMG has assumed $1,500 in consulting
services and legal fees incurred by the Fund in connection with these matters.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Effective April 13, 2004, the audit committee of the Trust requested that Ernst
& Young LLP ("E&Y") resign as the auditors of the Fund. Also effective July 14,
2004, upon the recommendation of the audit committee, the Trust selected
PricewaterhouseCoopers LLP ("PWC") as independent registered public accounting
firm to audit the books and records of the Fund for its fiscal year ending
December 31, 2004. The cessation of the relationship with E&Y was based on the
impairment of E&Y's independence resulting from the consummation of the merger
of FleetBoston Financial Corporation and Bank of America Corporation and
accordingly, E&Y's ability to provide audit services to the Fund.

      E&Y's report on the financial statements of the Fund for the past two
years did not contain an adverse opinion or disclaimer of opinion, and was not
qualified or modified as to uncertainty, audit scope or accounting principles.
During the period E&Y was engaged, there were no disagreements with E&Y on any
matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedure which, if not resolved to E&Y's satisfaction, would
have caused it to make reference to that matter in connection with its 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, 2004, the results of its operations, the changes in its net assets
and the financial highlights for the year 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 audit. 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, 2004 by
correspondence with the custodian and brokers, provides a reasonable basis for
our opinion. The statement of changes in net assets for the year ended December
31, 2003 and 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.

     officer or controller, or persons performing similar functions, regardless
     of whether these individuals are employed by the registrant or a third

     a provision of the code of ethics adopted in 2(a) above.

(c)  During the period covered by this report, there were not any waivers or
     implicit waivers to a provision of the code of ethics adopted in 2(a)
     above.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Trustees has determined that Jerome L. Duffy, who is a
member of the registrant's Board of Trustees and Audit Committee, qualifies as
an audit committee financial expert. Mr. Duffy is an independent trustee, as
defined in paragraph (a)(2) of this item's instructions.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Effective July 14, 2004, the registrant engaged new independent accountants.
Unless otherwise noted, fees disclosed below represent fees paid or accrued to
the current and predecessor principal accountants while each was engaged by the
registrant.

(a) Aggregate Audit Fees billed by the principal accountant for professional
services rendered during the fiscal years ended December 31, 2004 and December
31, 2003 are approximately as follows:

                                            2004              2003
                                            $82,000           $78,800

Audit Fees include amounts related to the audit of the registrant's annual
financial statements or services that are normally provided by the accountant in
connection with statutory and regulatory filings or engagements for those fiscal
years.

(b) Aggregate Audit-Related Fees billed by the principal accountant for
professional services rendered during the fiscal years ended December 31, 2004
and December 31, 2003 are approximately as follows:

                                            2004              2003
                                            $10,400           $16,000



Audit-Related Fees include amounts for assurance and related services by the
principal accountant that are reasonably related to the performance of the audit
of the registrant's financial statements and are not reported in Audit Fees
above. In both fiscal years 2004 and 2003, Audit-Related Fees include certain
agreed-upon procedures performed for semi-annual shareholder reports.

(c) Aggregate Tax Fees billed by the principal accountant for professional
services rendered during the fiscal years ended December 31, 2004 and December
31, 2003 are approximately as follows:

                                            2004              2003
                                            $11,000           $12,100

Tax Fees in both fiscal years 2004 and 2003 consist primarily of the review of
annual tax returns and include amounts for professional services by the
predecessor principal accountant for tax compliance, tax advice and tax
planning.

(d) Aggregate All Other Fees billed by the principal accountant for professional
services rendered during the fiscal years ended December 31, 2004 and December
31, 2003 are as follows:

                                            2004              2003
                                            $0                $0

All Other Fees include amounts for products and services provided by the
principal accountant, other than the services reported in paragraphs (a) through
(c) above.

None of the amounts described in paragraphs (a) through (d) above were approved
pursuant to the "de minimis" exception under paragraph (c)(7)(i)(C) of Rule 2-01
of Regulation S-X.

(e)(1) AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES

The policy of the registrant's Audit Committee is to specifically pre-approve
(i) all audit and non-audit (including audit related, tax and all other)
services provided by the registrant's independent auditor to the registrant and
individual funds (collectively "Fund Services") and (ii) all non-audit services
provided by the registrant's independent auditor to the funds' adviser or a
control affiliate of the adviser, that relate directly to the funds' operations
and financial reporting (collectively "Fund-related Adviser Services"). 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, 2004 and December 31, 2003 was zero.

(f) Not applicable.

(g) All non-audit fees billed by the registrant's accountant for services
rendered to the registrant for the fiscal years ended December 31, 2004 and
December 31, 2003 are disclosed in (b) through (d) of this Item.

During the fiscal years ended December 31, 2004 and December 31, 2003, there
were no Audit-Related Fees or Tax Fees that were approved for services to the
investment 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 adviser that provides ongoing services to the registrant under paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X. During the fiscal years ended
December 31, 2004 and December 31, 2003, All Other Fees that were approved
pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X were
approximately $93,500 and $95,000, respectively. For both fiscal years, All
Other Fees relate to internal controls reviews of the registrant's transfer
agent performed by the current principal accountant.

The percentage of Audit-Related Fees, Tax Fees and All Other Fees required to be
approved under paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X that were
approved under the "de minimis" exception during both fiscal years ended
December 31, 2004 and December 31, 2003 was zero.

(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. The Audit Committee
determined that the provision of such services is compatible with maintaining
the principal accountant's independence.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

Not applicable.

ITEM 6. SCHEDULE OF INVESTMENTS

The registrant's "Schedule I - Investments in securities of unaffiliated
issuers" (as set forth in 17 CFR 210.12-12) is included in Item 1 of this Form
N-CSR.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

Not applicable.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable.

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

Not applicable.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

On September 29, 2004, the registrant adopted procedures for consideration of
Trustee candidates submitted by shareholders. The Trust's Governance Committee
(the "Committee") is responsible for identifying and nominating candidates for
appointment as Trustees. Although the registrant's investment adviser, Trustees,
or shareholders may submit suggested candidates for Independent Trustees to the
Committee, neither the Committee nor the Independent Trustees as a group shall
consider those candidates on a preferential basis as opposed to other possible
candidates. Any shareholders may submit the name of a candidate for
consideration by the Committee by submitting the recommendation to the Trust's
Secretary in accordance with the procedures. A copy of these procedures, which
include the information required to be submitted in a shareholder nomination,
may be obtained by contacting the Secretary of the Trust, at the address of the
principal executive offices of the Trust. The Secretary will forward any such
recommendation to the Chairman of the Committee promptly upon receipt.

Recommendations for candidates for Trustees will be evaluated, among other
things, in light of whether the number of Trustees




is expected to change and whether the Trustees expect any vacancies. Shareholder
recommendations will be kept on file until active recruitment is underway.

ITEM 11. CONTROLS AND PROCEDURES.

(a)  The registrant's principal executive officer and principal financial
     officers, based on their evaluation of the registrant's disclosure controls
     and procedures as of a date within 90 days of the filing of this report,
     have concluded that such controls and procedures are adequately designed to
     ensure that information required to be disclosed by the registrant in Form
     N-CSR is accumulated and communicated to the registrant's management,
     including the principal executive officer and principal financial officer,
     or persons performing similar functions, as appropriate to allow timely
     decisions regarding required disclosure.

(b)  There were no changes in the registrant's internal control over financial
     reporting that occurred during the registrant's second fiscal quarter of
     the period covered by this report that has materially affected, or is
     reasonably likely to materially affect, the registrant's internal control
     over financial reporting.

ITEM 12. EXHIBITS.

(a)(1) Code of ethics required to be disclosed under Item 2 of Form N-CSR
attached hereto as Exhibit 99.CODE ETH.
