PRESIDENT'S MESSAGE
Liberty Variable Investment Trust

Dear Shareholder:

Columbia Management, the asset management division of Bank of America, is in the
final stages of a significant business integration effort. Over the last year,
we have been integrating various components of our various fund families,
including Liberty and SteinRoe, which will result in a single fund family that
covers a wide range of markets, sectors and asset classes. Our team of talented,
seasoned investment professionals will continue to strive to achieve strong
results within their investment categories. Our objective is not only to provide
our shareholders with the best products but also to enhance the breadth and
availability of our services. Given our ability to now leverage the size and
scale of the Columbia Management business, I am pleased that these efforts will
also result in substantial cost savings to the funds.

Our goal is to create a more simplified, clearly delineated product line.
Through thoughtful project planning and execution, we will initially reduce the
number of retail mutual funds from over 140 to fewer than 90. Earlier this year
several fund mergers and liquidations were successfully completed. As we work to
complete the remaining product and service provider consolidations in the coming
months, we remain committed to building a mutual fund business that meets, and
hopefully exceeds, your desire for personal financial solutions. We will
continue to strive for the highest standards of performance and service
excellence. The asset management business is in a time of transformation and we
are committed to being progressive and innovative in our approach to the
business. We value the confidence you have placed in us to assist you in
managing your funds during these changing times. As with all businesses within
Bank of America, we understand that your trust must be continuously earned and
will remain focused on producing results for you.

In the pages that follow, you'll find a discussion of the economic environment
during the period followed by a detailed report from the fund's manager or
managers on key factors that influenced performance. We encourage you to read
the manager reports carefully and discuss any questions you have with your
financial advisor. As always, we thank you for choosing Columbia Management. We
look forward to helping you keep your long-term financial goals on target in the
years to come.

Sincerely,

/s/ Christopher L. Wilson

PORTFOLIO MANAGER'S DISCUSSION
Colonial Small Cap Value Fund, Variable Series / June 30, 2005

Colonial Small Cap Value Fund, Variable Series seeks long-term growth by
investing primarily in smaller capitalization (small-cap) equities.

Stephen D. Barbaro has managed the fund since June 2002.

Small-cap stocks made little headway during the first half of 2005. Within the
sector, value stocks modestly outpaced growth stocks. The fund fell slightly
short of both the S&P Small Cap 600/ Barra Value Index and Russell 2000 Value
Index ("Russell")(1). It also trailed the average return of the Lipper Small-Cap
Value Funds Category(2).

   We continued to focus on companies with strong competitive and financial
positions, good earnings growth prospects and reasonable valuations. However,
the fund lost some ground relative to the Russell because the fund did not own
highly leveraged companies. These companies were among the period's best
performers, as investors rewarded companies that stretched for incremental
returns by adding debt to their balance sheets. In addition, the fund owned more
stocks than the index at the smaller end of the small-cap universe, a market
capitalization range from $100 million to $2 billion. Relatively larger-cap
stocks within the index outperformed small-cap stocks as the valuation gap
between them narrowed.

ENERGY AND UTILITIES DELIVERED MIXED RESULTS

Although the market was flat, energy and utilities stocks posted strong gains.
The fund's energy stocks were up nicely, even though they did not keep pace with
the sector's return in the index. Leveraged refiners were among the index's best
performers along with more expensive exploration and production stocks. We
missed out on these gains because neither industry met the standards of our
strategy. In utilities, where the fund had a below-average stake, the fund's
returns were positive but also lagged the sector return for the index. The fund
underperformed in this sector because we avoided owning the lower quality,
alternative energy companies that led the sector. However, we continue to
believe that it is prudent to focus on higher quality companies.

WEAK RETURNS FROM INDUSTRIALS

Although the industrials sector's overall return was flat for the period, the
fund's industrial stocks declined modestly. The fund did not keep pace as it did
not own the highly leveraged, lower quality industrial companies that led the
sector. A few smaller-cap industrial stocks in the portfolio also suffered steep
downturns, the result of moderately disappointing earnings. Financials, which
was the fund's largest sector weight, were also flat. The fund had investments
in banks, insurers and specialty finance companies, as well as a small stake in
real estate investments trusts. The fund's technology stocks declined during the
period, which was in line with the sector's return in the index.

POSITIVE STOCK SELECTION IN MATERIALS AND CONSUMER DISCRETIONARY

The fund's materials stocks declined, but far less than those in the Russell.
The fund emphasized coal, titanium, and building materials stocks, all of which
benefited from strong global demand and improved pricing. We reduced the fund's
stake in steel stocks--a fortunate move, because steel commodity prices softened
during the period. In the consumer discretionary sector, the fund generated
positive returns that beat the sector average. Specialty retailers did
especially well, including one company that was bought out at a substantial
premium and another that purchased a major competitor. The fund also owned a
tire retailer and building materials retailer that benefited from attractive
valuations and good earnings.

MORE NEUTRAL POSITIONING

To prepare for more moderate economic growth, we pared back on economically
sensitive sectors, including industrials and materials. In their place, we added
to our stakes in consumer staples and health care. We thought stocks in these
sectors offered relatively attractive valuations along with more predictable
earnings outlooks. In the spring, we also brought the fund's median market cap
in line with the index's, believing that smaller-cap stocks no longer offer much
of an advantage over larger size small-cap stocks. Going forward, we plan to
maintain our focus on companies with strong balance sheets, which we believe
have the potential to be long-term winners.

   Stephen D. Barbaro has managed the Colonial Small Cap Value Fund, Variable
Series since June 2002 and has been with advisor or its predecessors since 1976.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue or commence. The opinions expressed here are
strictly those of Columbia Management and are subject to change without notice.
Other divisions of Bank of America and/or affiliates of Columbia Management may
have opinions that are inconsistent with these opinions.

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

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

Value stocks are stocks of companies that may have experienced adverse business
or industry developments or may be subject to special risks that have caused the
stocks to be out of favor and, in the advisor's opinion, undervalued. If the
advisor's assessment of a company's prospects is wrong, the price of the
company's stock may fall or may not approach the value the advisor has placed on
it.

</Table>

The graph compares the results of a hypothetical $10,000 investment in the fund
with the indexes. The Indexes are unmanaged and returns for the indexes and the
fund include reinvested dividends and capital gains. It is not possible to
invest directly in an index. Investment earnings, if any, are income
tax-deferred until distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. Beginning in 2004, the Fund's benchmark was changed to the
Russell 2000 Value Index, an unmanaged index that measures the performance of
those Russell 2000 companies with lower price-to-book ratios and lower
forecasted growth values. The S&P Small Cap 600/Barra Value Index is an
unmanaged index that tracks the performance of value stocks, as determined by
low price-to-book ratios included in the S&P Small Cap 600 Index. Indices are
not investments, do not incur fees or expenses and are not professionally
managed. It is not possible to invest directly in an index. Securities in the
fund may not match those in an index.

Class B shares (newer class shares) performance information includes returns of
the fund's class A shares (the oldest existing fund class) for periods prior to
the inception of the newer class shares. These class A share returns were not
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
class A shares and the newer class shares. If differences in expenses were
reflected, the returns for the periods prior to the inception of the new class
of shares would be lower.

(1)  Index performance for the life of the fund is from May 19, 1998.
(2)  Index performance for the life of the fund is from May 31, 1998.
(3)  Inception date of class A shares (oldest existing share class).

UNDERSTANDING YOUR EXPENSES
Colonial Small Cap Value Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

Had the distributor not waived/reimbursed a portion of expenses, account values
at the end of the period would have been reduced.

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks long-term growth by investing primarily in
smaller capitalization (small-cap) equities.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

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

   INCOME RECOGNITION--Interest income is recorded on the accrual basis.
Corporate actions and dividend income are recorded on the ex-date except for
certain foreign securities which are recorded as soon after ex-date as the Fund
becomes aware of such, net of non-reclaimable tax withholdings. 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. If the Fund no longer owns the
applicable securities, any distributions received in excess of income are
recorded as realized gains.

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

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

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

                                       12

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

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 3. FEDERAL TAX INFORMATION

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                       ANNUAL FEE RATE
- ------------------------                       ---------------
                                                 
First $500 million                                  0.80%
$500 million to $1 billion                          0.75%
Over $1 billion                                     0.70%
</Table>

For the six months ended June 30, 2005, the Fund's annualized effective
investment advisory fee rate was 0.80%.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average daily net assets exceed $50 million, an additional monthly
fee. The additional fee rate is calculated by taking into account the fees
payable to State Street under the Outsourcing Agreement. This rate is applied to
the average daily net assets of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.028%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was less than 0.01%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Columbia and the Distributor have voluntarily agreed to waive
fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of brokerage commissions, interest, taxes and extraordinary expenses,
if any) will not exceed 1.10% annually of the Fund's average daily net assets.
The Distributor will first reimburse the Class B distribution fee up to 0.25%
annually to reach the 1.10% limit on Class B expenses. If additional
reimbursement is needed to meet the limit for each class, Columbia will then
reimburse other expenses to the extent necessary. If additional reimbursement is
still needed in order to reach the expense limit, Columbia will then waive a
portion of its investment advisory fee to the extent

                                       13
<Page>

necessary. Columbia or the Distributor, at their discretion, may revise or
discontinue this arrangement any time.

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

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$889 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $133,255,838 and
$64,402,443, respectively.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been

                                       14
<Page>

transferred to the Federal District Court in Maryland and consolidated in a
multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $3,699 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

The fund posted a slight gain for the first six months of 2005. However, this
gain was below the fund's peer group, the Lipper Variable Series General Bond
Category(1) average and its benchmark return during the same period. Adverse
results from the high-yield and currency markets were responsible for most of
the shortfall in performance.

A SHIFT IN HIGH-YIELD PREFERENCE

The high-yield market started the period on a strong note, essentially
continuing the positive momentum of 2004. However, this momentum was disrupted
in early May by the credit downgrades at Ford Motor and General Motors (0.1% and
0.1% of net assets, respectively). The bonds of both companies were reduced to
junk-bond status for the first time in their respective histories, and the
high-yield market responded by becoming more risk-averse. This shift in market
sentiment hurt the fund, because our high-yield investments emphasized
low-quality (CCC) companies while underweighting BB credits. And with high-yield
securities as a group underperforming the broader bond market, our 40%
commitment to this asset class was a drag on the fund's overall results.

MIXED RESULTS OVERSEAS

The fund's overseas investments are divided into two categories:
developed-market bonds (19.3% of net assets) and emerging-market bonds (15.1% of
net assets). Although developed-market bonds in their local currencies performed
as well or better than comparable US Treasury securities, these gains were
eliminated by the weakness in foreign currencies versus the US dollar. Stalled
economic growth in Europe and concern over the direction of the political union
caused the euro to backtrack after a prolonged period of market leadership.

   The fund experienced better results from its positions in emerging market
bonds, which were the single best-performing asset class during the period.
Higher commodity prices, steady global growth, and low interest rates produced
an environment in which many countries were able to grow their economies and
improve their fiscal profiles. The fund's investments in Russia, Panama,
Colombia, Mexico, and Brazil all made positive contributions to overall
performance.

REPOSITIONING THE PORTFOLIO

Although we didn't make any meaningful shifts to our asset allocations during
the period, we reduced the fund's overall currency exposure as the dollar
strengthened. In the near term, US interest rates and the trend toward a tighter
monetary policy could give support to the dollar, but we are mindful that
America's high budget and current account deficits represent a longer-term
concern.

   We expect growth in the US to be steady or slightly lower in the second half
of the year. All indications are that the Federal Reserve will continue to lift
short-term rates gradually as conditions permit. Long-term rates actually
declined slightly over the past six months, enabling the fund's holdings in US
government bonds to contribute positively to performance. With stable growth and
little evidence of inflation outside the commodities markets, we are maintaining
our commitment to the domestic bond market at around 24% of the overall
portfolio.

Economic and market conditions frequently change. There is no assurance that the

Strategic investing offers attractive income and total return opportunities, but
also involves certain risks. The value and return of your investment may
fluctuate as a result of changes in interest rates, the financial strength of
issuers of lower-rated bonds, foreign, political and economic developments, and
changes in currency exchange rates.

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

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

Investing in high-yield securities or "junk bonds" offers the potential for
higher current income and attractive total return, but involves certain risks.
Changes in economic conditions or other circumstances may adversely affect a
high-yield bond issuer's ability to make timely principal and interest payments.
High yield bonds issued by foreign entities have greater potential risks,
including foreign taxation, currency fluctuations, risks associated with
possible differences in financial standards and other monetary and political
risks.

</Table>

The graph compares the results of a hypothetical $10,000 investment in the fund
with the index. The Index is unmanaged and returns for the index and the fund
include reinvested dividends and capital gains. It is not possible to invest
directly in an index. Investment earnings, if any, are income tax-deferred until
distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. The Lehman Brothers Government/Credit Bond Index is an unmanaged
index that tracks the performance of a selection of US government and investment
grade US corporate bonds. Indices are not investments, do not incur fees or
expenses and are not professionally managed. It is not possible to invest
directly in an index. Securities in the fund may not match those in an index.

Class B shares (newer class shares) performance information includes returns of
the fund's class A shares (the oldest existing fund class) for periods prior to
the inception of the newer class shares. These class A share returns were not
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
class A shares and the newer class shares. If differences in expenses were
reflected, the returns for the periods prior to the inception of the new class
of shares would be lower.

UNDERSTANDING YOUR EXPENSES
Colonial Strategic Income Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Colonial Strategic Income Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Colonial Strategic Income Fund, Variable Series (the "Fund"), a series of
Liberty Variable Investment Trust (the "Trust") is a diversified portfolio. The
Trust is a Massachusetts business trust registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks current income consistent with prudent risk.
The Fund also seeks maximum total return.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

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

Forward currency exchange contracts are valued at the prevailing forward
exchange rate of the underlying currencies.

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

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of the New York Stock Exchange ("NYSE"). The
values of such securities used in computing the net asset value of the Fund's
shares are determined as of such times. Foreign currency exchange rates are
generally determined at 2:00 p.m. Eastern (U.S.) time. Occasionally, events
affecting the values of such foreign securities and such exchange rates may
occur between the times at which they are determined and the close of the
customary trading session of the NYSE, which would not be reflected in the
computation of the Fund's net asset value. If events materially affecting the
values of such foreign securities occur and it is determined that market
quotations are not reliable, then these foreign securities will be valued at
their fair value using procedures approved by the Board of Trustees.

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS--Forward foreign currency exchange
contracts are agreements to exchange one currency for another at a future date
at a specified price. These contracts are used to minimize the

                                       33
<Page>

exposure to foreign exchange rate fluctuations during the period between trade
and settlement date of the contracts. The Fund may utilize forward foreign
currency exchange contracts in connection with the settlement of purchases and
sales of securities. The Fund may also enter into these contracts to hedge
certain other foreign currency denominated assets. Contracts to buy generally
are used to acquire exposure to foreign currencies, while contracts to sell are
used to hedge the Fund's investments against currency fluctuations. Forward
currency contracts are valued daily at the current exchange rate of the
underlying currency, resulting in unrealized gains (losses) which become
realized at the time the foreign currency contracts are closed or mature.
Realized and unrealized gains (losses) arising from such transactions are
included in net realized and unrealized gains (losses) on foreign currency
transactions. The use of forward currency contracts does not eliminate
fluctuations in the prices of the Fund's portfolio securities. While the maximum
potential loss from such contracts is the aggregate face value in U.S. dollars
at the time the contract was opened, exposure is typically limited to the change
in value of the contract (in U.S. dollars) over the period it remains open. The
Fund could also be exposed to risk if the counterparties of the contracts are
unable to fulfill the terms of the contracts.

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

   MORTGAGE DOLLAR ROLL TRANSACTIONS--The Fund may enter into mortgage dollar
roll transactions. A mortgage dollar roll transaction involves a sale by the
Fund of investments from its portfolio with an agreement by the Fund to
repurchase similar, but not identical, securities at an agreed upon price and
date. During the period between the sale and repurchase, the Fund will not be
entitled to accrue interest and receive principal payment on the securities
sold. Mortgage dollar roll transactions involve the risk that the market value
of the securities sold by the Fund may decline below the repurchase price of
those securities. In the event the buyer of the securities under a mortgage
dollar roll transaction files for bankruptcy or becomes insolvent, the Fund's
use of proceeds of the transaction may be restricted pending a determination by
or with respect to the other party. The Fund identifies U.S. Government
securities or other liquid high grade debt obligations in an amount equal to the
mortgage dollar roll transactions.

   DELAYED DELIVERY SECURITIES--The Fund may trade securities on other than
normal settlement terms, including securities purchased or sold on a
"when-issued" basis. This may increase the risk if the other party to the
transaction fails to deliver and causes the Fund to subsequently invest at less
advantageous prices. The Fund identifies cash or liquid portfolio securities in
an amount equal to the delayed delivery commitment.

   INCOME RECOGNITION--Interest income is recorded on the accrual basis. Premium
and discount are amortized and accreted, respectively, on all debt securities.
Corporate actions and dividend income are recorded on the ex-date except for
certain foreign securities which are recorded as soon after ex-date as the Fund
becomes aware of such, net of non-reclaimable tax withholdings. Fee income
attributable to mortgage dollar roll transactions is recorded on the accrual
basis over the term of the transaction.

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

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

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

   FEDERAL INCOME TAX STATUS--The Fund intends to qualify each year as a
"regulated investment company" under Subchapter M of the Internal Revenue Code,
as amended, and will distribute substantially all of its taxable income, if any,
for its tax year, and as such will not be subject to federal income taxes. In
addition, the Fund intends to distribute in each calendar year substantially all
of its net investment income, capital gains and certain other amounts, if any,
such that the Fund should not be subject

                                       34
<Page>

to federal excise tax. Therefore, no federal income or excise tax provision is
recorded.

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                  ANNUAL FEE RATE
- ------------------------                  ---------------
                                            
First $500 million                             0.60%
$500 million to $1 billion                     0.55%
$1 billion to $1.5 billion                     0.52%
Over $1.5 billion                              0.49%
</Table>

For the six months ended June 30, 2005, as a result of the settlement with the
New York Attorney General discussed in Note 6, the Fund's annualized effective
investment advisory fee rate was 0.59%.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average daily net assets exceed $50 million, an additional monthly
fee. The additional fee rate is calculated by taking into account the fees
payable to State Street under the Outsourcing Agreement. This rate is applied to
the average daily net assets of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.059%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was less than 0.01%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Columbia and the Distributor have voluntarily agreed to waive
fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of brokerage commissions, interest, taxes and extraordinary expenses,
if any) will not exceed 1.00% annually of the Fund's average daily net assets.
The Distributor will first reimburse the Class B distribution fee up to 0.25%
annually to reach the 1.00% limit on Class B expenses. If additional
reimbursement is needed to meet the limit for each class, Columbia will then
reimburse other expenses to the extent

                                       35
<Page>

necessary. If additional reimbursement is still needed in order to reach the
expense limit, Columbia will then waive a portion of its investment advisory fee
to the extent necessary. Columbia or the Distributor, at their discretion, may
revise or discontinue this arrangement any time.

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

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$831 to Columbia for such services. This amount is included in "Other expenses"

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $28,102,128 and
$33,374,307 of which $51,187 was U.S. Government securities.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

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

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

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

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be

                                       36
<Page>

distributed in accordance with a distribution plan to be developed by an
independent distribution consultant, who is acceptable to the SEC staff and the
Columbia Funds' independent trustees. The distribution plan must be based on a
methodology developed in consultation with the Columbia Group and the Fund's
independent trustees and not unacceptable to the staff of the SEC. At this time,
the distribution plan is still under development. As such, any gain to the Fund
or its shareholders can not currently be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $1,939 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

PORTFOLIO MANAGERS' DISCUSSION
Columbia High Yield Fund, Variable Series / June 30, 2005

Columbia High Yield Fund, Variable Series seeks a high level of current income
by investing primarily in lower-rated fixed income securities. Capital
appreciation is a secondary goal when consistent with the goal of high current
income.

Jeffrey L. Rippey and Kurt M. Havnaer are portfolio managers for the fund. Mr.
Rippey has managed or co-managed the fund and its predecessors since March 1998.
Mr. Havnaer has co-managed the fund and its predecessor since September 2000.

During the six-month period ended June 30, 2005, the bond market remained
relatively stable though there were some slight gains to be seen. Even though
the Federal Reserve increased the federal funds rate by one percentage point to
3.25% during this period, long-term interest rates dropped by about three-tenths
of one percentage point. The high-yield sector showed modest gains, with higher
quality securities slightly outperforming lower quality credits. This pattern
strengthened during the second quarter and was favorable to the fund, which
finished the first half of the year roughly in line with its benchmark, the
Merrill Lynch US High Yield, Cash Pay Only Index(1).

MIXED RESULTS FROM SECTOR ALLOCATIONS

The fund's performance relative to its benchmark was dependent not only on
specific securities held during the period, but also on what sectors were
underweighted. Some of these underweight sectors posted weak returns and
therefore the fund wasn't affected as much by their poor performance. For
instance, the fund had no exposure to air transportation, which underperformed
during the six-month period. Record high fuel prices continue to plague the
airlines. The fund was also underweight in the auto sector. While auto sales
have held reasonably firm despite the high cost of oil, the deteriorating
finances at Ford Motor and General Motors caused both companies to suffer credit
downgrades in May and accelerated a flight to quality within the high-yield
market. The fund had no exposure to either Ford Motor or General Motors.

   The fund's underweight position in the telecommunications sector, on the
other hand, represented a missed opportunity. Many telecom companies have made
demonstrable improvements to their balance sheets, and investors have responded
by bidding up the prices for their bonds.

FOCUS ON INDIVIDUAL HOLDINGS

Individual companies from many different industries aided the fund with their
strong performance over the past six months. Bonds of HCA (Hospital Corporation
of America) performed well as the company's efforts to pay down its debt
surpassed market expectations (1.4% of net assets). TECO Energy (a diversified
holding company that includes Tampa Electric) performed well due in part to its
success in divesting merchant power assets and returning to its core utility
business (1.0% of net assets). Rogers Wireless advanced upon entering into an
attractive merger (1.0% of net assets). Leading drill pipe supplier Grant
Prideco benefited from the strong upturn in the energy sector (0.7% of net
assets). As a result, Grant Prideco called one of its two bonds that the fund
owned, at favorable terms.

   The portfolio also contained some disappointments. Cinemark USA, one of the
country's largest movie exhibitors, suffered from reduced theater attendance
(1.1% of net assets). Finlay Enterprises, which operates jewelry departments for
several major retail chains, has been viewed cautiously by investors following
the announcement that one of its larger clients is being acquired. More than 50%
of Finlay's sales derive from its relationship with this retail chain, and the
fate of that business once the retailer has been acquired is uncertain. We
eliminated our position in Finlay by the end of the period. Finally, containers
sector declined amid sluggish demand for corrugated boxes and declining prices
for containerboards (1.4% of net assets).

ENCOURAGED BY CURRENT ECONOMIC CLIMATE

The fund did not make any fundamental changes to its portfolio structure during
the period. We continue to believe that the current economic environment of
stable growth and relatively low interest rates is favorable for the high-yield
market. Steady growth has enabled many companies to improve their balance sheets
and credit ratings. Within the high-yield market, the recent leadership of
higher quality issues is an encouraging sign, because the average credit quality
of our holdings is high relative to our peer group. While this stance caused our
performance to lag somewhat in 2004, we are encouraged by the increasing number
of portfolio holdings drawing closer to investment-grade status.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue or commence. The opinions expressed here are
strictly those of Columbia Management and are subject to change without notice.
Other divisions of Bank of America and/or affiliates of Columbia Management may
have opinions that are inconsistent with these opinions.

An investment in the Columbia High Yield Fund, Variable Series may involve
certain risks, including the credit quality of individual issuers, possible
prepayments, market or economic developments and yield and share price
fluctuations due to changes in interest rates. When interest rates go up, bond
prices typically drop, and vice versa.

Investing in high yield securities or "junk bonds" offers the potential for
higher current income and attractive total return but involves certain risks.
Changes in economic conditions or other circumstances may adversely affect a
high-yield bond issuer's ability to make timely principal and interest payments.

Holdings are disclosed as of June 30, 2005, and are subject to change.

     that tracks the performance of non-investment-grade corporate bonds.

</Table>

The graph compares the results of a hypothetical $10,000 investment in the fund
with the index. The Index is unmanaged and returns for the index and the fund
include reinvested dividends and capital gains. It is not possible to invest
directly in an index. Investment earnings, if any, are income tax-deferred until
distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. The Merrill Lynch US High Yield, Cash Pay Only Index is an
unmanaged index that tracks the performance of non-investment-grade corporate
bonds. Indices are not investments, do not incur fees or expenses and are not
professionally managed. It is not possible to invest directly in an index.
Securities in the fund may not match those in an index.

Class B shares (newer class shares) performance information includes returns of
the fund's class A shares (the oldest existing fund class) for periods prior to
the inception of the newer class shares. These class A share returns were not
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
class A shares and the newer class shares. If differences in expenses were
reflected, the returns for the periods prior to the inception of the new class
of shares would be lower.

(1)  Index performance for the life of the fund is from March 3, 1998.

(2)  Inception date of class A shares (oldest existing share class) is
     March 3, 1998.

UNDERSTANDING YOUR EXPENSES
Columbia High Yield Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

Had the investment advisor and its affiliates not waived/reimbursed a portion of
expenses, account values at the end of the period would have been reduced.

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Columbia High Yield Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Columbia High Yield Fund, Variable Series (the "Fund"), a series of Liberty
Variable Investment Trust (the "Trust") is a diversified portfolio. The Trust is
a Massachusetts business trust registered under the Investment Company Act of
1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks a high level of current income by investing
primarily in lower-rated fixed income securities. Capital appreciation is a
secondary goal when consistent with the goal of high current income.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

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

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

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of the New York Stock Exchange ("NYSE"). The
values of such securities used in computing the net asset value of the Fund's
shares are determined as of such times. Foreign currency exchange rates are
generally determined at 2:00 p.m. Eastern (U.S.) time. Events affecting the
values of such foreign securities and such exchange rates may occur between the
times at which they are determined and the close of the customary trading
session of the NYSE, which would not be reflected in the computation of the
Fund's net asset value. If events materially affecting the values of such
foreign securities occur and it is determined that market quotations are not
reliable, then these foreign securities will be valued at their fair value using
procedures approved by the Board of Trustees.

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

   REPURCHASE AGREEMENTS--The Fund may engage in repurchase agreement
transactions with institutions that the Fund's investment advisor has determined
are creditworthy. The Fund, through its custodian, receives delivery of
underlying securities collateralizing a repurchase agreement. Collateral is at
least equal, at all times, to the value of the repurchase obligation including
interest. A repurchase agreement transaction involves certain risks in the event
of

                                       50
<Page>

default or insolvency of the counterparty. These risks include possible delays
or restrictions upon the Fund's ability to dispose of the underlying securities
and a possible decline in the value of the underlying securities during the
period while the Fund seeks to assert its rights.

   INCOME RECOGNITION--Interest income is recorded on the accrual basis. Premium
and discount are amortized and accreted, respectively, on all debt securities.
Corporate actions and dividend income are recorded on the ex-date.

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

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

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations) and realized
and unrealized gains (losses) are allocated to each class of the Fund on a daily
basis for purposes of determining the net asset value of each class. Income and
expenses are allocated to each class based on the settled shares method, while
realized and unrealized gains (losses) are allocated based on the relative net
assets of each class.

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

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS            ANNUAL FEE RATE
- ------------------------            ---------------
                                       
First $1 billion                          0.60%
Next $500 million                         0.55%
Over $1.5 billion                         0.50%
</Table>

                                       51
<Page>

For the six months ended June 30, 2005, the Fund's annualized effective
investment advisory fee rate was 0.60%.

   ADMINISTRATION FEE--Columbia provides administrative and other services to
the Fund. The Fund is not charged a fee for these services.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives an
annual fee based on the average daily net assets of the Fund as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS             ANNUAL FEE RATE
- ------------------------             ---------------
                                   
Under $50 million                     $     25,000
$50 million to $200 million           $     35,000
$200 million to $500 million          $     50,000
$500 million to $1 billion            $     85,000
Over $1 billion                       $    125,000
</Table>

The Fund also pays additional fees for pricing services based on the number of
securities held by the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.035%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $5,000.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was 0.01%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Effective January 1, 2005, Columbia has voluntarily agreed to
waive fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of distribution fees, brokerage commissions, interest, taxes and
extraordinary expenses, if any) will not exceed 0.60% annually of the Fund's
average daily net assets. Prior to January 1, 2005, Columbia voluntarily
reimbursed certain fees of the Fund at an annual rate up to 0.27% of the Fund's
average daily net assets. For the six months ended June 30, 2005, fees
reimbursed by Columbia amounted to 0.11% of the Fund's average daily net assets.
In addition, the Distributor has voluntarily agreed to waive Class B
distribution fees at an annual rate of 0.19% of the Class B average daily net
assets. Columbia or the Distributor, at their discretion, may revise or
discontinue these arrangements any time.

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

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$790 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $51,641,599 and
$13,414,041, respectively.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

   HIGH-YIELD SECURITIES--Investing in high-yield securities may involve greater
credit risk and considerations not typically associated with investing in U.S.
government bonds and other higher quality fixed income securities. These
securities are non-investment grade securities, often referred to as "junk
bonds." Economic downturns may disrupt the high yield market and impair the
ability of issuers to repay principal and interest. Also, an increase in
interest rates would likely have an adverse impact on the value of such
obligations. Moreover, high-yield securities

                                       52
<Page>

may be less liquid to the extent that there is no established secondary market.

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

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

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. The lawsuit alleges that defendants violated common
law duties to fund shareholders as well as

                                       53
<Page>

sections of the Investment Company Act of 1940, by failing to ensure that the
Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $1,155 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

PORTFOLIO MANAGERS' DISCUSSION
Columbia International Fund, Variable Series / June 30, 2005

Columbia International Fund, Variable Series seeks long-term growth.

Penelope L. Burgess and Deborah F. Snee are the fund's portfolio managers. Ms.
Burgess and Ms. Snee have co-managed the fund since July 2004. Ms. Burgess has
been with the advisor and its predecessors or affiliate organizations since
1993. Ms. Snee has been with the advisor and its predecessors or affiliate
organizations since 1999.

International equity markets produced mixed returns during the first half of
2005, as investors came to terms with rising oil prices and the potential for a
slowdown in global economic growth. In this environment, the portfolio had
relatively strong returns in Europe, Singapore and Hong Kong. The portfolio
suffered, however, from investments in Japan, a market that performed poorly.
Underexposure to Australia also held back results. In addition, the portfolio
had no exposure to Royal Dutch and missed out on the stock's strong returns, the
result of higher oil prices. Performance was also negatively affected by the
appreciation of the US dollar, which eroded investment returns that were
denominated in local currencies and then converted to the dollar.

ENERGY STOCKS DROVE PERFORMANCE

Oil prices rose 35% during this six-month period, and the portfolio's overweight
position in the energy sector made a positive contribution to performance.
Returns were enhanced by OMV AG, an Austria-based oil and gas producer that is
gaining access to central and Eastern Europe through acquisitions (0.4% of net
assets). The portfolio also benefited from Canada's EnCana Corp., one of the
largest oil and gas exploration companies in North America (0.9% of net assets).
EnCana's reported annual production growth and operating margins are
significantly above its industry peers.

TWO PRIMARY THEMES INFLUENCED STOCK SELECTION

We emphasized companies that we believed were likely to raise their dividend
payouts and/or benefit from increased capital expenditures. As a result, we were
overweight in the industrials sector, and the fund's investment in Vinci SA, a
French construction company, was one of the top stocks in the portfolio (1.3% of
net assets). We also added investments in health care, favoring beaten down
pharmaceuticals that were selling at attractive valuations and that had solid
prospects for growth. We added to AstraZeneca (United Kingdom), which had been
an underperformer, and invested in Sanofi-Aventis (France) (1.6% and 1.2% of net
assets, respectively). Both companies rose in value.

   We sold some long-term holdings that had been leaders for more than a year.
We eliminated Alpha Bank, a financial services company located in Greece, due to
slower lending growth and rising costs. We also sold Erste Bank, an Austrian
bank facing increased competition from western European banks. We were concerned
that Erste Bank would not be able to sustain its high level of earnings growth
in a softening economy.

A BIGGER PRESENCE IN ASIA ADDED TO RETURNS

We significantly boosted the weight in Singapore from 0.3% of net assets at the
end of December 2004 to 2.6% of net assets at the end of June 2005. We favored
Singapore because its economy appeared to be more resilient than other Asian
economies. We felt that consumers were poised to increase their spending and
believed that many Singaporean companies had the potential to increase their
earnings and dividend payouts. In addition, valuations were attractive, with
many stocks selling at significant discounts to their peers. The fund's
companies in Singapore were some of the best performers. We also raised exposure
to Hong Kong, an area that benefited from a stronger economy and a particularly
vibrant real estate sector.

EUROPE AND JAPAN REMAIN ATTRACTIVE

Moving into the second half of 2005, we plan to continue seeking large companies
that have the potential to increase their dividend payouts. We will also
maintain our emphasis on companies that we believe will benefit from capital
spending. Despite the forecasts for a slower economy in Europe, we believe there
are opportunities in several markets. We are also fairly optimistic about Japan.
Economic data, such as rising consumer confidence and higher bank loan demand,
we believe favors Japan. We intend to keep at least a benchmark weight in the
country.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue or commence. The opinions expressed here are
strictly those of Columbia Management and are subject to change without notice.
Other divisions of Bank of America and/or affiliates of Columbia Management may
have opinions that are inconsistent with these opinions.

An investment in the Columbia International Fund, Variable Series may present
certain risks, including stock market fluctuations that occur in response to
economic and business developments. International investing may involve certain
risks, including foreign taxation, currency fluctuations, risks associated with
possible differences in financial standards and other monetary and political
risks.

Since the fund may invest a greater percentage of its total assets in a single
issuer, it may have increased risk compared to a similar diversified fund.

Holdings are disclosed as of June 30, 2005 and are subject to change.

The graph compares the results of a hypothetical $10,000 investment in the fund
with the indexes. The Indexes are unmanaged and returns for the indexes and the
fund include reinvested dividends and capital gains. It is not possible to
invest directly in an index. Investment earnings, if any, are income
tax-deferred until distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. Beginning in 2005, the Fund's benchmark was changed to MSCI EAFE
Index. The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far
East (EAFE) Index is a free float-adjusted market capitalization index that is
designed to measure developed market equity performance, excluding the US and
Canada. The MSCI All Country World ex US Index is an unmanaged index of global
stock market performance that includes developed and emerging markets but
excludes the United States. Indices are not investments, do not incur fees or
expenses and are not professionally managed. It is not possible to invest
directly in an index. Securities in the fund may not match those in an index.

Class B shares (newer class shares) performance information includes returns of
the fund's class A shares (the oldest existing fund class) for periods prior to
the inception of the newer class shares. These class A share returns were not
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
class A shares and the newer class shares. If differences in expenses were
reflected, the returns for the periods prior to the inception of the new class
of shares would be lower.

(1)  Inception date of class A shares (oldest existing share class) is May 2,
     1994.

UNDERSTANDING YOUR EXPENSES
Columbia International Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

Had the investment advisor not waived/reimbursed a portion of expenses, account
values at the end of the period would have been reduced.

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Columbia International Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Columbia International Fund, Variable Series (the "Fund"), a series of Liberty
Variable Investment Trust (the "Trust") is a non-diversified portfolio. The
Trust is a Massachusetts business trust registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks long-term growth.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

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

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of the New York Stock Exchange ("NYSE"). The
values of such securities used in computing the net asset value of the Fund's
shares are determined as of such times. Foreign currency exchange rates are
generally determined at 2:00 p.m. Eastern (U.S.) time. Occasionally, events
affecting the values of such foreign securities and such exchange rates may
occur between the times at which they are determined and the close of the
customary trading session of the NYSE, which would not be reflected in the
computation of the Fund's net asset value. If events materially affecting the
values of such foreign securities occur and it is determined that market
quotations are not reliable, then these foreign securities will be valued at
their fair value using procedures approved by the Board of Trustees. The Fund
may use a systematic fair valuation model provided by an independent third party
to value securities principally traded in foreign markets in order to adjust for
possible stale pricing that may occur between the close of the foreign exchanges
and the time for valuation. If a security is valued at a "fair value", such
value is likely to be different from the last quoted market price for the
security.

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

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

   FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS--Forward foreign currency
exchange contracts are agreements to exchange one currency for another at a
future date at a specified price. These contracts are used to minimize the
exposure to foreign exchange rate fluctuations during the period between trade
and settlement date of the contracts. The Fund may utilize forward foreign
currency exchange contracts in connection with the settlement of purchases and
sales of securities. The Fund may also enter into these contracts to hedge
certain other foreign currency denominated assets. Contracts to buy generally
are used to acquire exposure to foreign currencies, while contracts to sell are
used to hedge the Fund's investments against currency fluctuations. Forward
currency contracts are valued daily at the current exchange rate of the
underlying currency, resulting in unrealized gains (losses) which become
realized at the time the foreign currency contracts are closed or mature.
Realized and unrealized gains (losses) arising from such transactions are
included in net realized and unrealized gains (losses) on foreign currency
transactions. The use of forward currency contracts does not eliminate
fluctuations in the prices of the Fund's portfolio securities. While the maximum
potential loss from such contracts is the aggregate face value in U.S. dollars
at the time the contract was opened, exposure is typically limited to

                                       66
<Page>

the change in value of the contract (in U.S. dollars) over the period it remains
open. The Fund could also be exposed to risk if the counterparties of the
contracts are unable to fulfill the terms of the contracts.

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

   INCOME RECOGNITION--Interest income is recorded on the accrual basis.
Corporate actions and dividend income are recorded on the ex-date, except for
certain foreign securities which are recorded as soon after ex-date as the Fund
becomes aware of such, net of non-reclaimable tax withholdings.

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

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

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

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

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS             ANNUAL FEE RATE
- ------------------------             ---------------
                                       
First $500 million                        0.87%
$500 million to $1 billion                0.82%
$1 billion to $1.5 billion                0.77%
$1.5 billion to $3 billion                0.72%
$3 billion to $6 billion                  0.70%
Over $6 billion                           0.68%
</Table>

For the six months ended June 30, 2005, as a result of the settlement with the
New York Attorney General discussed in Note 6, the Fund's annualized effective
investment advisory fee rate was 0.86%.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average daily net assets exceed $50 million, an additional monthly
fee. The additional fee rate is calculated by taking into account the fees
payable to State Street under the Outsourcing Agreement. This rate is applied to
the average daily net assets of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.053%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was 0.01%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Effective February 1, 2005, Columbia has voluntarily agreed to
waive fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of service and distribution fees, brokerage commissions, interest,
and extraordinary expenses, if any) will not exceed 0.95%. Columbia, at its
discretion, may revise or discontinue this arrangement any time.

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

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$779 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $22,712,504 and
$29,572,568, respectively.

                                       68
<Page>

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

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

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

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   ISSUER FOCUS--As a non-diversified fund, the Fund may invest a greater
percentage of its total assets in the securities of fewer issuers than a
diversified fund. The Fund may, therefore, have a greater risk of loss from a
few issuers than a similar fund that invests more broadly.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

                                       69
<Page>

federal court in Massachusetts and the federal Judicial Panel has conditionally
ordered its transfer to the MDL.

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $902 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

PORTFOLIO MANAGERS' DISCUSSION
Liberty Growth & Income Fund, Variable Series / June 30, 2005

Liberty Growth & Income Fund, Variable Series seeks long-term growth and income.

During the six-month period ended June 30, 2005, the fund was co-managed by
Brian Cunningham, Gregory M. Miller and Richard Dahlberg. As of June 30, 2005,
the fund's lead manager is Lori J. Ensinger and co-managers are David I.
Hoffman, Noah J. Petrucci and Diane L. Sobin. Ms. Ensinger has been with
Columbia Management Advisors, Inc. ("Columbia") or its affiliates since 2001.
Mr. Hoffman has been with Columbia or its affiliates since August 2001. Mr.
Petrucci has been with Columbia or its affiliates since February 2002. Ms. Sobin
has been with Columbia or its affiliates since August 2001.

The fund delivered a modest but positive return for the first half of the year,
reflecting a market that was generally directionless but one in which value
stocks outpaced growth. Corporate profits continued their vigorous expansion.
Yet, stock market returns were muted because of indications that the economy
might be slowing under the weight of high energy prices and repeated interest
rate hikes. Beginning in 2005, the fund's benchmark was changed from the S&P 500
Index to the Russell 1000 Value Index ("Russell")(1). We believe that the
Russell, with its greater emphasis on companies with lower price-to-book ratios
and lower forecasted growth rates, more accurately reflects the type of
securities in which the fund invests.

UTILITIES, ENERGY AND HEALTH CARE WERE OUT FRONT

Rising prices for natural gas and continued progress in restructuring put
further impetus behind the shares of TXU, the portfolio's best-performing
utility (0.8% of net assets). TXU also sold off certain assets, allaying fears
of dividend cuts and boosting its stock further.

   Five of the fund's energy holdings ranked among the fund's top ten performers
during the period. Soaring prices for crude oil boosted shares of
ConocoPhillips, Exxon Mobil, BP PLC, and Marathon Oil (3.2%, 4.4%, 2.0% and 0.7%
of net assets, respectively). Halliburton, a leading provider of products and
services to the energy industry, benefited from increased activity on the global
energy market (0.5% of net assets).

   Health care stocks benefited as investors sought sectors that might do well
in a slower growth environment. The fund enjoyed good results in Aetna and
CIGNA, two leading health maintenance organizations (1.2% and 0.6% of net
assets, respectively). Bausch & Lomb, maker of a broad line of eye care products
and a recent addition to the portfolio, moved higher (0.3% of net assets).
Health care giant Johnson & Johnson, which markets products for consumers and
medical professionals, also rode renewed interest in the segment (0.8% of net
assets).

TECHNOLOGY, FINANCIALS AND MATERIALS DECLINED

Technology stocks delivered some of the period's worst returns. International
Business Machines saw shares fall sharply in April after earnings fell shy of
investor expectations (0.9% of net assets). Printer maker Lexmark International
suffered from slow sales of supplies (0.8% of net assets). Lexmark International
and its competitors rely on continued revenue from ink cartridge sales to
compensate for the narrow margins earned on printers. In addition, Hewlett
Packard (not in the portfolio) is regaining market share it had lost to Lexmark.

   Technology has suffered primarily for two reasons. First, businesses seem to
lack confidence in the durability of the current expansion and, second, a
slowing of growth overseas. Consequently, firms that might otherwise be
investing in technology have been holding back on capital expenditures,
preferring to build up cash as they watch developments unfold. Financials also
underperformed as capital markets and commercial lending remained relatively
quiet.

   Dramatic growth in 2004 from China and India had created shortages and pushed
up prices of materials and metals that year. Global demand has now eased, prices
have slumped, and stocks of producers have followed. MeadWestvaco fell amid
concerns that a slowing economy would shrink demand for its containerboard and
cardboard boxes (1.2% of net assets). Weakness in the automotive industry hurt
results at PPG Industries, a new holding for the fund, as sales of auto glass
and paint pigments sank (0.4% of net assets).

FOCUSING ON VALUE AND RISING PROFITS

The fund is positioned to focus on attractively valued companies that offer
earnings growth through margin expansion and revenue growth. We continue to seek
out companies that produce rising returns on capital, and that return capital to
shareholders through rising dividends and share repurchases.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue or commence. The opinions expressed here are
strictly those of Columbia Management and are subject to change without notice.
Other divisions of Bank of America and/or affiliates of Columbia Management may
have opinions that are inconsistent with these opinions.

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

Value stocks are stocks of companies that may have experienced adverse business
or industry developments or may be subject to special risks that have caused the
stocks to be out of favor and, in the advisor's opinion, undervalued. If the
advisor's assessment of a company's prospects is wrong, the price of the
company's stock may fall or may not approach the value the advisor has placed on
it.

Holdings are disclosed as of June 30, 2005, and are subject to change.

(1)  The Standard & Poor's (S&P) 500 Index is an unmanaged index that tracks the
     performance of 500 widely held, large-capitalization US stocks. The Russell
     1000 Value Index is an unmanaged index that measures the performance of
     those Russell 1000 Index companies with lower price-to-book ratios and
     lower forecasted growth values.

</Table>

The graph compares the results of a hypothetical $10,000 investment in the fund
with the indexes. The Indexes are unmanaged and returns for the indexes and the
fund include reinvested dividends and capital gains. It is not possible to
invest directly in an index. Investment earnings, if any, are income
tax-deferred until distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. The fund's primary benchmark was changed to the Russell 1000
Value Index. Previously, the fund's returns were compared to the S&P 500 Index.
The Russell 1000 Value Index is an unmanaged index that measures the performance
of those Russell 1000 Index companies with lower price-to-book ratios and lower
forecasted growth values. The Standard & Poor's (S&P) 500 Index is an unmanaged
index that tracks the performance of 500 widely held, large-capitalization U.S.
stocks. Indices are not investments, do not incur fees or expenses and are not
professionally managed. It is not possible to invest directly in an index.
Securities in the fund may not match those in an index.

Class B shares (newer class shares) performance information includes returns of
the fund's class A shares (the oldest existing fund class) for periods prior to
the inception of the newer class shares. These class A share returns were not
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
class A shares and the newer class shares. If differences in expenses were
reflected, the returns for the periods prior to the inception of the new class
of shares would be lower.

(1)  Inception date of class A shares (oldest existing share class) is July 5,
     1994.

UNDERSTANDING YOUR EXPENSES
Liberty Growth & Income Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

Had the investment advisor and its affiliates not waived/reimbursed a portion of
expenses, account values at the end of the period would have been reduced.

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Liberty Growth & Income Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Liberty Growth & Income Fund, Variable Series (the "Fund"), a series of Liberty
Variable Investment Trust (the "Trust") is a diversified portfolio. The Trust is
a Massachusetts business trust registered under the Investment Company Act of
1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks long-term growth and income.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

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

   INCOME RECOGNITION--Interest income is recorded on the accrual basis.
Corporate actions and dividend income are recorded on the ex-date. 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. If the Fund no longer owns the
applicable securities, any distributions received in excess of income are
recorded as realized gains.

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

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

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                  ANNUAL FEE RATE
- ------------------------                  ---------------
                                            
First $500 million                             0.77%
$500 million to $1 billion                     0.72%
$1 billion to $1.5 billion                     0.67%
$1.5 billion to $3 billion                     0.62%
$3 billion to $6 billion                       0.60%
Over $6 billion                                0.58%
</Table>

For the six months ended June 30, 2005, as a result of the settlement with the
New York Attorney General discussed in Note 6, the Fund's annualized effective
investment advisory fee rate was 0.76%.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average daily net assets exceed $50 million, an additional monthly
fee. The additional fee rate is calculated by taking into account the fees
payable to State Street under the Outsourcing Agreement. This rate is applied to
the average daily net assets of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.028%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was less than 0.01%

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Effective January 1, 2005, Columbia has voluntarily agreed to
waive fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of distribution fees, brokerage commissions, interest, taxes and
extraordinary expenses, if any) will not exceed 0.80% annually of the Fund's
average daily net assets. Prior to January 1, 2005, Columbia voluntarily
reimbursed certain fees of the Fund at the annual rate of 0.11% of the Fund's
average daily net assets. In addition, the Distributor has voluntarily agreed to
waive Class B distribution fees at the annual rate of 0.02% of the Class B
average daily net assets. Columbia or the Distributor, at their discretion, may
revise or discontinue these arrangements any time.

                                       82
<Page>

   CUSTODY CREDITS--The Fund has an agreement with its custodian bank under
which custody fees may be reduced by balance credits. These credits are recorded
as a reduction of total expenses on the Statement of Operations. The 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. For the six months ended on June 30, 2005, there were no such
credits.

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$876 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $50,537,904 and
$72,506,949, respectively.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

                                       83
<Page>

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $2,981 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

PORTFOLIO MANAGER'S DISCUSSION
Liberty S&P 500 Index Fund, Variable Series / June 30, 2005

Liberty S&P 500 Index Fund, Variable Series seeks capital appreciation by
matching the performance of a benchmark index that measures the investment
returns of stocks of large US companies.

James May, a principal of State Street Global Advisors(SSgA), is the portfolio
manager of the fund.

Effective August 22, 2005, Vikram J. Kurian, PhD, will begin managing the fund,
replacing James May, a principal of SSgA. Dr. Kurian is a portfolio manager of
Columbia Management and has been associated with Columbia Management or its
predecessors since January 2000.

Large-company stocks ended the first half of 2005 in negative territory. Despite
a strong second quarter, US stocks were driven down by investor concern over
historically high oil prices and rising interest rates. The S&P 500 Index(1)
returned negative 0.81% for the six-month period ended June 30, 2005, and the
fund's performance was comparable to the index for the period.

   Mid-cap stocks outperformed both large- and small-cap stocks during the first
half of the year as measured by the Russell indices. Value stocks gained ground
relative to growth as the six-month period wore on. The S&P 500/Barra Value
Index rose 0.09% while the S&P 500/Barra Growth Index returned negative
1.73%(2).

ENERGY AND UTILITY SECTORS WERE TOP PERFORMERS

Sector performance within the S&P 500 was mixed during this reporting period.
Energy and utilities were the top performing sectors. Energy companies enjoyed
ample pricing power. Utility stocks attracted investors because of their
increasing income potential.

   Most sectors in the index turned in negative performances for the first half
of the year. Materials and consumer discretionary stocks were the most
disappointing. Higher energy costs and a challenging pricing environment
adversely affected many companies in the materials sector. Aluminum giant Alcoa
and steelmaker Nucor (0.2% and 0.1% of net assets, respectively) both slipped at
the end of the period. Downturns in Time Warner (0.7% of net assets) and the
major auto stocks were the primary cause of the decline in consumer
discretionary sector. Technology and industrial stocks also fell during the
period. Declines in Microsoft and International Business Machines (2.2% and 1.1%
of net assets, respectively) hurt the technology sector. Among the industrials,
General Electric (3.3% of net assets) was a notable loser, stumbling on a
disappointing profits forecast. Several transportation companies also fell as a
result of their inability to pass on higher energy costs to customers.

ABOUT OUR MANAGEMENT STYLE

Cost-effective trade execution is a hallmark of our management style. We also
manage the fund with a full replication investment strategy. As a result, the
fund generally holds each of the 500 securities included in the S&P 500 Index in
approximately the same weight as the company's representation in the index.
Because the fund incurs trading costs in seeking to maintain the appropriate
weight of each security in the index, its return is typically lower than that of
the index. In addition, the fund may be required to sell securities to meet
redemption demand or buy securities to invest new monies that come into the
fund.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue or commence. The opinions expressed here are
strictly those of Columbia Management and are subject to change without notice.
Other divisions of Bank of America and/or affiliates of Columbia Management may
have opinions that are inconsistent with these opinions.

Equity funds are subject to stock market fluctuations that occur in response to
economic and business developments.

The primary risks involved with investing in the fund include equity risk,
market risk and tracking error risk. Unlike the S&P 500 Index, the fund incurs
administrative expenses and transaction costs in trading stocks. The composition
of the S&P 500 Index and the stocks held by the fund may occasionally diverge.

Holdings are disclosed as of June 30, 2005, and are subject to change.

(1)  The Standard & Poor's (S&P) 500 Index is an unmanaged index that tracks the
     performance of 500 widely held, large-capitalization US stocks.

(2)  The S&P 500/Barra Value Index is an unmanaged index that tracks the
     performance of companies in the S&P 500 Index with lower price-to-book
     ratios. The S&P 500/Barra Growth Index is an unmanaged index that tracks
     the performance of companies in the S&P 500 Index with higher price-to-book
     ratios.

The graph compares the results of a hypothetical $10,000 investment in the fund
with the index. The Index is unmanaged and returns for the index and the fund
include reinvested dividends and capital gains. It is not possible to invest
directly in an index. Investment earnings, if any, are income tax-deferred until
distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. The Standard & Poor's (S&P) 500 Index is an unmanaged index that
tracks the performance of 500 widely held, large capitalization US stocks.
Indices are not investments, do not incur fees or expenses and are not
professionally managed. It is not possible to invest directly in an index.
Securities in the fund may not match those in an index. Performance numbers
reflect all fund expenses, but do not include any insurance charges imposed by
your insurance company's separate accounts. If performance included the effect
of these additional charges, it would be lower.

(1)  Index performance for the life of the fund is from May 30, 2000.

UNDERSTANDING YOUR EXPENSES
Liberty S&P 500 Index Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Liberty S&P 500 Index Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Liberty S&P 500 Index Fund, Variable Series (the "Fund"), a series of Liberty
Variable Investment Trust (the "Trust") is a diversified portfolio. The Trust is
a Massachusetts business trust registered under the Investment Company Act of
1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks capital appreciation by matching the
performance of a benchmark index that measures the investment returns of stocks
of large U.S. companies.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

Futures contracts are valued at the settlement price established each day by the
board of trade or exchange on which they are traded.

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under general supervision of the Board of Trustees. If a
security is valued at a "fair value" such value is likely to be different from
the last quoted market price for the security.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

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

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

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

                                       99
<Page>

possible decline in the value of the underlying securities during the period
while the Fund seeks to assert its rights.

   INCOME RECOGNITION--Interest income is recorded on the accrual basis.
Corporate actions and dividend income are recorded on the ex-date. 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. If the Fund no longer owns the
applicable securities, any distributions received in excess of income are
recorded as realized gains.

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

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

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 3. FEDERAL TAX INFORMATION

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee at the annual rate
of 0.20%.

For the six months ended June 30, 2005, the Fund's annualized effective
investment advisory fee rate was 0.20%.

   SUB-ADVISORY FEE--State Street Global Advisors ("SSgA") has been retained by
Columbia as sub-advisor to the Fund. As the sub-advisor, SSgA is responsible for
daily investment operations, including placing all orders for the purchase and
sale of portfolio securities for the Fund. Columbia, from the investment
advisory fee it receives, pays SSgA a monthly sub-advisory fee at the following
annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                  ANNUAL FEE RATE
- ------------------------                  ---------------
                                          
First $50 million                            $ 25,000
Over $50 million                                 0.05%
</Table>

Effective August 22, 2005, SSgA will no longer sub-advise the Fund. Columbia
will run the Fund's day to day business including placing orders for the
purchase and sales of the Fund's portfolio securities.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee

                                       100
<Page>

of $10,000 paid monthly, and in any month that the Fund's average daily net
assets exceed $50 million, an additional monthly fee. The additional fee rate is
calculated by taking into account the fees payable to State Street under the
Outsourcing Agreement. This rate is applied to the average daily net assets of
the Fund for that month. The Fund also pays additional fees for pricing services
based on the number of securities held by the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.085%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was 0.01%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Columbia and the Distributor have voluntarily agreed to waive
fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of brokerage commissions, interest, taxes and extraordinary expenses,
if any) will not exceed 0.75% annually of the Fund's average daily net assets.
The Distributor will first reimburse the Class B distribution fee up to 0.25%
annually to reach the 0.75% limit on Class B expenses. If additional
reimbursement is needed to meet the limit for each class, Columbia will then
reimburse other expenses to the extent necessary. If additional reimbursement is
still needed in order to reach the expense limit, Columbia will then waive a
portion of its investment advisory fee to the extent necessary. Columbia or the
Distributor, at their discretion, may revise or discontinue this arrangement any
time.

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

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$777 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $1,515,622 and
$2,853,987, respectively.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

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

                                       101
<Page>

independent distribution consultant (see below). The Columbia Funds have also
voluntarily undertaken to implement certain governance measures designed to
maintain the independence of their boards of trustees. The NYAG Settlement also,
among other things, requires Columbia and its affiliates, Banc of America
Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia
Funds, Nations Funds and other mutual funds management fees collectively by $32
million per year for five years, for a projected total of $160 million in
management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $653 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.

PORTFOLIO MANAGERS' DISCUSSION
Liberty Select Value Fund, Variable Series / June 30, 2005

Liberty Select Value Fund, Variable Series seeks long-term growth.

Diane L. Sobin, the lead manager, along with David I. Hoffman, Lori J. Ensinger
and Noah J. Petrucci co-manage the fund. Ms. Sobin, Mr. Hoffman and Ms. Ensinger
have been with Columbia Management Advisors, Inc. or its predecessors or
affiliate organizations since 2001. Mr. Petrucci has been affiliated with the
advisor or its affiliates since 2002.

Mid-cap value stocks were among the best-performing asset classes during the
six-month period ended June 30, 2005. The fund's investments in energy, health
care and utility stocks drove performance during the period. However, a lack of
exposure to refiners in the energy sector detracted from performance relative to
the fund's benchmark. The fund's position in stocks that are sensitive to
economic activity, including industrial and materials stocks, also detracted
from performance. Investor concerns that the economy was slowing translated into
weak performance for both sectors. However, we remain confident in the global
economy's potential to expand and the fund remains overweight in industrial and
materials stocks relative to the index.

POSITIVE RETURNS FROM ENERGY, UTILITIES, HEALTH CARE AND CONSUMER POSITIONS

As the price of oil climbed above $60 during the period, energy stocks rose
strongly. The fund's positions in XTO Energy (1.2% of net assets), a US-based
natural gas company, and Amerada Hess (1.2% of net assets), an integrated oil
company, were the fund's strongest performers. The defensive utilities sector,
with its rising cash flow and excellent dividend growth during the period, was
another stand-out and we added to the fund's utility positions. Constellation
Energy Group (1.6% of net assets), advanced on the strength of its exposure to
rising power prices. Exelon (1.4% of net assets), a nuclear power generator,
also benefited from rising power prices as the company's cost structure was
lower than competitive gas and coal electric generators and its share price
reflected this advantage. Within health care, HCA (0.9% of net assets), a
national hospital company, made a solid contribution to the fund's performance.
The fund's position in Federated Department Stores ("Federated") (1.2% of net
assets) also did well. Despite higher gasoline prices, which took a bite out of
consumer pocketbooks, spending remained strong and Federated enjoyed sales
growth that beat expectations.

CYCLICAL INDUSTRIES TOOK A BREATHER

The fund's exposure to cyclical companies detracted from performance as
investors move away from sectors that rely on economic growth for their
earnings. Georgia-Pacific (0.9% of net assets), a leading manufacturer of paper
and building products, was hurt by rising energy prices, which increased the
company's operating costs and lowered near term earnings prospects. In the
industrial sector, industrial equipment manufacturers Parker Hannifin and
Ingersoll-Rand (0.8% and 0.9% of net assets, respectively) reported weaker order
trends for the first half of 2005, and both stocks lost some ground. We reduced
the fund's exposure to industrials and to consumer cyclicals. However, the fund
remains overweight in industrials relative to the index because we believe that
they have the potential to do well if the global economy continues to expand.

LOOKING AHEAD

We believe that the fund is well positioned to take advantage of the
opportunities in mid-cap stocks. We plan to continue to focus on
attractively-valued companies that offer earnings growth potential through sales
growth and profit margin expansion. In addition, we plan to seek companies that
produce rising returns on capital and that return a portion of earnings to
shareholders in the form of dividend payments. Companies that repurchase their
own shares are also attractive candidates for the portfolio.

Economic and market conditions frequently change. There is no assurance that the
trends described here will continue. The opinions expressed here are strictly
those of Columbia Management and are subject to change without notice. Other
divisions of Bank of America and/or affiliates of Columbia Management may have
opinions that are inconsistent with these opinions.

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

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

Value stocks are stocks of companies that may have experienced adverse business
or industry developments or may be subject to special risks that have caused the
stocks to be out of favor and, in the advisor's opinion, undervalued. If the
advisor's assessment of a company's prospects is wrong, the price of the
company's stock may fall or may not approach the value the advisor has placed on
it.

Holdings are disclosed as of June 30, 2005, and are subject to change.

The graph compares the results of a hypothetical $10,000 investment in the fund
with the index. The Index is unmanaged and returns for the index and the fund
include reinvested dividends and capital gains. It is not possible to invest
directly in an index. Investment earnings, if any, are income tax-deferred until
distribution, at which time taxes will become due.

Total return performance includes changes in share price and reinvestment of all
distributions. The Russell Midcap Value Index is an unmanaged index that
measures the performance of those Russell Midcap Index companies with lower
price-to-book ratios and lower forecasted growth values. Indices are not
investments, do not incur fees or expenses and are not professionally managed.
It is not possible to invest directly in an index. Securities in the fund may
not match those in an index.

(1) Index performance for the life of the fund is from May 30, 2000.

UNDERSTANDING YOUR EXPENSES
Liberty Select Value Fund, Variable Series / June 30, 2005

As a fund shareholder, you incur two types of costs. There are transaction
costs, which generally include sales charges on purchases and may include
redemption or exchange fees. There are also ongoing costs, which generally
include investment advisory, Rule 12b-1 fees and other fund expenses. The
information on this page is intended to help you understand your ongoing costs
of investing in the fund and to compare this cost 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 period. The amount listed in the "hypothetical" column assumes that the
return each year is 5% before expenses and includes the actual expense ratio.
You should not use the hypothetical account value and expenses to estimate
either your actual account balance at the end of the period or the expenses you
paid during this reporting period.

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 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

</Table>

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

Had the distributor not waived/reimbursed a portion of expenses, account values
at the end of the period would have been reduced.

It is important to note that the expense amounts shown in the table are meant to
highlight only ongoing costs of investing in the share class of 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 examples provided are 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.

COMPARE WITH OTHER FUNDS

Since all mutual funds are required to include the same hypothetical
calculations about expenses in shareholder reports, you can use this information
to compare the ongoing cost of investing in the fund with other funds. To do so,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of other funds. As you compare hypothetical
examples of other 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, 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.

NOTES TO FINANCIAL STATEMENTS
Liberty Select Value Fund, Variable Series / June 30, 2005 (Unaudited)

NOTE 1. ORGANIZATION

Liberty Select Value Fund, Variable Series (the "Fund"), a series of Liberty
Variable Investment Trust (the "Trust") is a diversified portfolio. The Trust is
a Massachusetts business trust registered under the Investment Company Act of
1940, as amended, as an open-end management investment company.

   INVESTMENT GOAL--The Fund seeks long-term growth.

   FUND SHARES--The Fund may issue an unlimited number of shares and offers two
classes of shares: Class A and Class B. Each share class has its own expense
structure. Shares of the Fund are available exclusively as a pooled funding
vehicle for variable annuity contracts ("VA Contracts") and Variable Life
Insurance Policies ("VLI Policies") offered by the separate accounts of certain
life insurance companies ("Participating Insurance Companies"). The
Participating Insurance Companies and their separate accounts own all the shares
of the Fund.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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

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

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

Investments for which market quotations are not readily available, or have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Board of Trustees. If a
security is valued at a "fair value", such value is likely to be different from
the last quoted market price for the security.

Debt securities generally are valued by pricing services approved by the Fund's
Board of Trustees, based upon market transactions for normal, institutional-size
trading units of similar securities. The services may use various pricing
techniques which take into account appropriate factors such as yield, quality,
coupon rate, maturity, type of issue, trading characteristics and other data, as
well as broker quotes. Debt securities for which quotations are readily
available are valued at an over-the-counter or exchange bid quotation.

   SECURITY TRANSACTIONS--Security transactions are accounted for on the trade
date. Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

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

   INCOME RECOGNITION--Interest income is recorded on the accrual basis.
Corporate actions and dividend income are recorded on the ex-date. 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. If the Fund no longer owns the
applicable securities, any distributions received in excess of income are
recorded as realized gains.

   DETERMINATION OF CLASS NET ASSET VALUES--All income, expenses (other than
class-specific expenses, as shown on the Statement of Operations), and realized
and unrealized gains (losses), are allocated to each class of the Fund on a
daily basis, based on the relative net assets of each class, for purposes of
determining the net asset value of each class.

   FEDERAL INCOME TAX STATUS--The Fund intends to qualify each year as a
"regulated investment company" under Subchapter M of the Internal Revenue Code,
as amended, and will distribute substantially all of its taxable income, if any,
for its tax year, and as such will not be subject to federal income taxes. In
addition, the Fund intends to distribute in each calendar year substantially all
of its

                                       113
<Page>

net investment income, capital gains and certain other amounts, if any, such
that the Fund should not be subject to federal excise tax. Therefore, no federal
income or excise tax provision is recorded.

   DISTRIBUTIONS TO SHAREHOLDERS--Distributions to shareholders are recorded on
ex-date. Dividends from net investment income, if any, are declared and
distributed at least annually. Net realized capital gains, if any, are
distributed at least annually. All dividends and distributions are reinvested in
additional shares of the Fund at net asset value as of the record date of the
distribution.

NOTE 3. FEDERAL TAX INFORMATION

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

   INVESTMENT ADVISORY FEE--Columbia Management Advisors, Inc. ("Columbia"), an
indirect wholly owned subsidiary of Bank of America Corporation ("BOA"), is the
investment advisor to the Fund and provides administrative and other services to
the Fund. Columbia receives a monthly investment advisory fee based on the
Fund's average daily net assets at the following annual rates:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                  ANNUAL FEE RATE
- ------------------------                  ---------------
                                            
First $500 million                             0.70%
$500 million to $1 billion                     0.65%
Over $1 billion                                0.60%
</Table>

For the six months ended June 30, 2005, the Fund's annualized effective
investment advisory fee rate was 0.70%.

   PRICING AND BOOKKEEPING FEES--Columbia is responsible for providing pricing
and bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated
those functions to State Street Corporation ("State Street"). As a result,
Columbia pays the total fees received to State Street under the Outsourcing
Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average daily net assets exceed $50 million, an additional monthly
fee. The additional fee rate is calculated by taking into account the fees
payable to State Street under the Outsourcing Agreement. This rate is applied to
the average daily net assets of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund.

For the six months ended June 30, 2005, the annualized effective pricing and
bookkeeping fee rate for the Fund, inclusive of out-of-pocket expenses, was
0.028%.

   TRANSFER AGENT FEE--Columbia Funds Services, Inc. (the "Transfer Agent"), an
affiliate of Columbia, provides shareholder services to the Fund and has
subcontracted with Boston Financial Data Services ("BFDS") to serve as
sub-transfer agent. For such services, the Transfer Agent receives a monthly
fee, at the annual rate of $7,500.

For the six months ended June 30, 2005, the Fund's annualized effective transfer
agent fee rate was 0.02%.

   DISTRIBUTION FEES--Columbia Funds Distributor, Inc. (the "Distributor"), an
affiliate of Columbia, is the principal underwriter of the Fund. The Fund has
adopted a 12b-1 plan which requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.25% of the average daily net assets
attributable to Class B shares.

   FEE WAIVERS--Columbia and the Distributor have voluntarily agreed to waive
fees and reimburse the Fund for certain expenses so that total expenses
(exclusive of brokerage commissions, interest, taxes and extraordinary expenses,
if any) will not exceed 1.10% annually of the Fund's average daily net assets.
The Distributor will first reimburse the Class B distribution fee up to 0.25%
annually to reach the 1.10% limit on Class B expenses. If additional
reimbursement is needed to meet the limit for each class, Columbia will then
reimburse other expenses to the extent necessary. If additional reimbursement is
still needed in order to reach the expense limit, Columbia will then waive a
portion of its investment advisory fee to the extent necessary. Columbia or the
Distributor, at their discretion, may revise or discontinue this arrangement any
time.

   CUSTODY CREDITS--The Fund has an agreement with its custodian bank under
which custody fees may be reduced by balance credits. These credits are recorded
as a reduction of total expenses on the Statement of Operations. The 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.

                                       114
<Page>

   FEES PAID TO OFFICERS AND TRUSTEES--With the exception of one officer, all
officers of the Fund are employees of Columbia or its affiliates and receive no
compensation from the Fund. The Board of Trustees appointed a Chief Compliance
Officer to the Fund in accordance with federal securities regulations. The Fund,
along with other affiliated funds, will pay its pro-rata share of the expenses
associated with the Office of the Chief Compliance Officer. The Fund's fee for
the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

   OTHER--Columbia provides certain services to the Fund related to
Sarbanes-Oxley compliance. For the six months ended June 30, 2005, the Fund paid
$771 to Columbia for such services. This amount is included in "Other expenses"
on the Statement of Operations.

NOTE 5. PURCHASES AND SALES OF SECURITIES

For the six months ended June 30, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $14,883,152 and
$16,420,592, respectively.

NOTE 6. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

   INDUSTRY FOCUS--The Fund may focus its investments in certain industries,
subjecting it to greater risk than a fund that is more diversified.

   LEGAL PROCEEDINGS--On February 9, 2005, Columbia and the Distributor
(collectively, the "Columbia Group") entered into an Assurance of Discontinuance
with the New York Attorney General ("NYAG") (the "NYAG Settlement") and
consented to the entry of a cease-and-desist order by the Securities and
Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG
Settlement are referred to collectively as the "Settlements". The Settlements
contain substantially the same terms and conditions as outlined in the
agreements in principle which Columbia Group entered into with the SEC and NYAG
in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other
things, to: pay $70 million in disgorgement and $70 million in civil money
penalties; cease and desist from violations of the antifraud provisions and
certain other provisions of the federal securities laws; maintain certain
compliance and ethics oversight structures; retain an independent consultant to
review the Columbia Group's applicable supervisory, compliance, control and
other policies and procedures; and retain an independent distribution consultant
(see below). The Columbia Funds have also voluntarily undertaken to implement
certain governance measures designed to maintain the independence of their
boards of trustees. The NYAG Settlement also, among other things, requires
Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP
Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other
mutual funds management fees collectively by $32 million per year for five
years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in
settlement amounts described above will be distributed in accordance with a
distribution plan to be developed by an independent distribution consultant, who
is acceptable to the SEC staff and the Columbia Funds' independent trustees. The
distribution plan must be based on a methodology developed in consultation with
the Columbia Group and the Fund's independent trustees and not unacceptable to
the staff of the SEC. At this time, the distribution plan is still under
development. As such, any gain to the Fund or its shareholders can not currently
be determined.

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

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A
copy of the NYAG Settlement is available as part of the Bank of America
Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed
suit against certain funds, the Trustees of the Columbia Funds, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities. More than 300 cases including those
filed against entities unaffiliated with the funds, their Boards, FleetBoston
Financial Corporation and its affiliated entities and/or Bank of America
Corporation and its affiliated entities have been transferred to the Federal
District Court in Maryland and consolidated in a multi-district proceeding (the
"MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the
MDL have been consolidated under the lead case. The fund derivative plaintiffs
allege that the funds were harmed by market timing and late trading activity and
seek, among other things, removal of the trustees of the Columbia Funds, removal
of the Columbia Group, disgorgement of all management fees and monetary damages.

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

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

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 Funds and Columbia. 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 Fund 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.

In 2004, certain Columbia funds, advisers and affiliated entities were named as
defendants in certain purported shareholder class and derivative actions making
claims, including claims under the Investment Company and the Investment
Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees
and expenses paid by the funds are excessive and that the advisers and their
affiliates inappropriately used fund assets to distribute the funds and for
other improper purpose. On March 2, 2005, the actions were consolidated in the
Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The
plaintiffs filed a consolidated amended complaint on June 9, 2005.

The Fund and the other defendants to these actions, including Columbia and
various of its affiliates, certain other mutual funds advised by Columbia and
its affiliates, and various directors of such funds, have denied these
allegations and are contesting the plaintiffs' claims. These proceedings are
ongoing, however, based on currently available information, Columbia believes
that these lawsuits are without merit, that the likelihood they will have a
material adverse impact on any fund is remote, and that the lawsuits are not
likely to materially affect its ability to provide investment management
services to its clients, including the Fund.

For the six months ended June 30, 2005, Columbia has assumed $517 of legal,
consulting services and Trustees' fees incurred by the Fund in connection with
these matters.
