Dear Shareholder:

In 2004, Colonial Funds became part of Columbia Management, the asset
management division of Bank of America, one of the largest, most respected
financial institutions in the United States. As a direct result of this merger,
a number of changes are in the works that we believe offer significant
potential benefits for our shareholders. First, some funds may be merged in
order to eliminate redundancies, others may be liquidated and fund management
teams will be aligned to maximize performance potential. You will receive more
detailed information about these changes if your fund is affected and you may
be asked to vote on certain fund changes. In this matter, your timely response
will enable us to implement the changes in 2005.

As a result of these changes, we believe we will offer shareholders an even
stronger lineup of investment options. What will not change as we enter this
next phase of consolidation is our commitment to the highest standards of
performance and our dedication to superior service. Change for the good has
another name: it's called improvement. It helps move us forward, and we believe
that it represents progress for all our shareholders in their quest for
long-term financial success.

In the pages that follow, you'll find a detailed report from the fund's
managers on key factors that influenced your fund's performance. We hope that
you will read the manager reports carefully and discuss any questions you might
have with your financial advisor.

As always, we thank you for choosing Colonial Funds. We appreciate your
continued confidence. And, 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 Report

For the six-month period ended May 31, 2005, Colonial New York Insured
Municipal Fund had a return of 6.79% based on its market price. Changes in the
market price of the fund's shares reflect investor demand and are not
necessarily linked directly to changes in net asset value. The fund returned
5.55%, based on investment at net asset value. The fund's return was in line
with the average return of its peer group, the Lipper New York Insured
Municipal Debt Funds Category, which was 5.74%/1/.

Non-callable issues, hospital bonds boosted returns

The fund's position in non-callable bonds in the long and intermediate maturity
ranges, some purchased more than two years ago, helped boost the fund's return
as they rose in value during the period. (A non-call provision means that the
issuer cannot redeem the bonds prior to maturity.) Holdings in the hospital
sector were also solid performers. The prices of both Sloan- Kettering Hospital
and New Island Hospital bonds (4.1% and 2.8% of total investments,
respectively) rose after a better-than-expected Medicaid reimbursement package
was passed by Congress during the period./2/ This higher-yielding sector of the
municipal market also benefited from an environment of relatively low to
declining interest rates among intermediate and long-term maturities, which
made lower quality issues attractive to yield-seeking investors.

The fund's dividend dropped as short-term interest rates rose and the fund was
required to raise its payout to preferred shareholders. The fund earned some of
its income through leverage, which comes from preferred shares issued in 1999.
We invested the proceeds from the preferred shares in longer maturity,
higher-yielding bonds and pay out to preferred shareholders a short-term rate
influenced by the federal funds rate--the overnight rate at which banks lend
each other money. As the fed funds rate climbed during the period, the payout
rate to preferred shareholders rose, reducing the income earned by the fund. In
addition, leverage adds volatility to the fund, but continued to give the fund
an income advantage over non-leveraged funds.

Insurance sector update

The bond insurance industry has gained several participants, adding to
competition, yet is dominated by established companies characterized by
ultraconservative underwriting standards. The industry continues to diversify
from traditional municipal business as international opportunities mature.
MBIA, the world's largest bond insurer, has received subpoena requests from
state and federal authorities covering several points of interest and is fully
cooperating with investigators. Based on available information to date, we
remain comfortable in MBIA's underwriting model and claims paying ability and
continue to approve their municipal insured bonds for purchase.

Portfolio Manager's Report (continued)

Short-maturity bonds, US Treasury hedge detracted from performance

The fund's short-term holdings detracted from performance. Yields on short-term
bonds rose and prices fell in response to the Federal Reserve's continued cycle
of interest rate increases. The fund's sizeable holdings in intermediate-term
bonds (10-15 years) also contributed to its modest underperformance. These
bonds remained relatively flat while longer maturity bonds (20 plus years)
fared better in response to news of slightly slower economic growth.

In addition, a hedge involving US Treasuries dampened the fund's return during
the period. The intention of the hedge was to reduce the fund's sensitivity to
interest rate changes and bring it in line with that of its peers. However, by
the end of the period the hedge had not fully achieved its desired results.

/s/ Kimberly A.Campbell

Kimberly Campbell has been the portfolio manager of Colonial New York Insured
Municipal Fund since October 2003. Ms. Campbell has been with Columbia
Management Advisors, Inc. or its predecessors or affiliate organizations since
1995.

On May 31, 2005, the fund's Board of Trustees approved a plan of liquidation of
the Colonial New York Insured Municipal Fund. On June 10, 2005, the fund
announced that it had completed the liquidation of its assets, including its
portfolio securities, pursuant to the plan of liquidation.

Performance data quoted represents past performance and current performance may
be lower or higher. Past performance is no guarantee of future results.

Tax-exempt investing offers current tax-exempt income, but it also involves
special risks. The value of the fund will be affected by interest rate changes
and the creditworthiness of issues held in the fund. When interest rates go up,
bond prices generally drop and vice versa. Interest income from certain
tax-exempt bonds may be subject to certain state and local taxes and, if
applicable, the alternative minimum tax. Capital gains are not exempt from
income taxes.

Investing in high-yield or "junk bonds" offers the potential for higher income
than investments in investment-grade bonds but they also have a higher degree
of risk. Changes in economic conditions or other circumstances may adversely
affect a high-yield bond issuer's ability to make timely principal and interest
payments.

Single-state municipal bond funds pose additional risks due to limited
geographical diversification.

                                    [GRAPHIC]


Notes to Financial Statements

May 31, 2005 (Unaudited)


Note 1. Organization

Colonial New York Insured Municipal Fund (the "Fund") is a Massachusetts
business trust registered under the Investment Company Act of 1940 (the "Act"),
as amended, as a non-diversified, closed-end management investment company.

Investment Goal

The Fund seeks to provide current income generally exempt from ordinary federal
income tax and New York State and City personal income tax.

Fund Shares

The Fund may issue an unlimited number of common shares. On December 20, 1999,
the Fund issued 564 Auction Preferred Shares ("APS").

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.

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 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.

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.

Notes to Financial Statements (continued)

May 31, 2005 (Unaudited)


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. Original issue discount is
accreted to interest income over the life of the security with a corresponding
increase in the cost basis. Premium and discount are amortized and accreted,
respectively, on all debt securities.

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 tax-exempt or 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 common shareholders are recorded on the ex-date. Distributions
to Auction Preferred shareholders are recorded daily and payable at the end of
each dividend period. Each dividend payment period for the APS is generally
seven days. The applicable dividend rate for the APS on May 31, 2005, was
1.93%. For the six months ended May 31, 2005, the Fund declared dividends to
Auction Preferred shareholders amounting to $126,635, representing an average
dividend rate of 1.80% per APS.

Note 3. Federal Tax Information

The tax character of distributions paid during the year ended November 30, 2004
was as follows:



                                              November 30,
                                                  2004

                     Distributions paid from:
                      Tax-Exempt Income        $1,709,277
                      Ordinary Income               7,356
                      Long-Term Capital Gains          --


Unrealized appreciation and depreciation at May 31, 2005, based on cost of
investments for federal income tax purposes, was:


                                               
                     Unrealized appreciation      $3,850,379
                     Unrealized depreciation          (3,896)
                                                  ----------
                     Net unrealized appreciation  $3,846,483
                                                  ----------


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 0.65% of the
Fund's average weekly net assets, including assets applicable to the APS.
Columbia contractually agreed to waive a portion of its investment advisory fee
through November 30, 2005, so that such fee will not exceed 0.40% annually.

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 weekly net assets, including assets applicable to APS,
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 weekly net assets,
including assets applicable to APS, 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 May 31, 2005, the Fund's annualized
effective pricing and bookkeeping fee rate, inclusive of out-of-pocket
expenses, was 0.093% of the Fund's average weekly net assets, including assets
applicable to APS.

Fee Waivers

Columbia has voluntarily agreed to reimburse the Fund for certain expenses so
that total expenses (exclusive of investment advisory fees, brokerage
commissions, interest, taxes and extraordinary expenses, if any) will


                                                                           10

Notes to Financial Statements (continued)

May 31, 2005 (Unaudited)

not exceed 0.20% annually of the Fund's average weekly net assets, including
assets applicable to APS. 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 May 31, 2005, the Fund paid $763 to
Columbia for such services. This amount is included in "Other expenses" on the
Statement of Operations.

Note 5. Portfolio Information

For the six months ended May 31, 2005, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $-- and $1,508,285,
respectively.

Note 6. Preferred Shares

The Fund currently has outstanding 564 APS. The APS are redeemable at the
option of the Fund on any dividend payment date at the redemption price of
$25,000 per share, plus an amount equal to any dividends accumulated on a daily
basis unpaid through the redemption date (whether or not such dividends have
been declared).

Under the Act, the Fund is required to maintain asset coverage of at least 200%
with respect to the APS as of the last business day of each month in which any
APS are outstanding. Additionally, the Fund is required to meet more stringent
asset coverage requirements under the terms of the APS Agreement and in
accordance with the guidelines prescribed by the APS' rating agencies. Should
these requirements not be met, or should dividends accrued on the APS not be
paid, the Fund may be restricted in its ability to declare dividends to common
shareholders or may be required to redeem certain APS. At May 31, 2005, there
were no such restrictions on the Fund.

Note 7. Disclosure of Significant Risks and Contingencies

Concentration of Credit Risk

The Fund holds investments that are insured by private insurers who guarantee
the payment of principal and interest in the event of default or that are
supported by a letter of credit. Each of the Fund's insurers is rated AAA by
Moody's Investor Services, Inc., except Radian Asset Assurance, Inc. which is
rated AA by Standard & Poor's. At May 31, 2005, private insurers who insured
greater than 5% of the total investments of the Fund were as follows:



                                                    % of Total
                 Insurer                            Investments
                 ---------------------------------- -----------
                                                 
                 MBIA Insurance Corp.                  38.3%
                 Ambac Assurance Corp.                 20.1
                 Financial Security Assurance, Inc.    16.2


Geographic Concentration

The Fund has greater than 5% of its total investments at May 31, 2005 invested
in debt obligations issued by the state of New York and its respective
political subdivisions, agencies and public authorities. The Fund is more
susceptible to economic and political factors adversely affecting issuers of
the state's municipal securities than are municipal bond funds that are not
concentrated to the same extent in these issuers.

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.

Notes to Financial Statements (continued)

May 31, 2005 (Unaudited)


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 Columbia Funds Distributor, Inc.
(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 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, the market price of fund shares could decline.

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,


                                                                           12

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.

Note 8. Subsequent Event

On May 31, 2005, the Fund's Board of Trustees approved a plan of liquidation of
the Fund. On June 10, 2005, the Fund announced that it had completed the
liquidation of its assets, including its portfolio securities, pursuant to the
plan of liquidation.

   period.
(c)Effective December 1, 2001, the Fund adopted the provisions of the AICPA
   Audit and Accounting Guide for Investment Companies and began accreting
   market discount on all debt securities. The effect of this change for the
   year ended November 30, 2002 was to increase the net investment income per
   share by $0.01, increase the net realized and unrealized loss per share by
   $0.01, increase the ratio of net investment income to average net assets
   from 7.30% to 7.38% and increase the ratio of net investment income
   (adjusted for dividend payments to preferred shareholders) from 6.54% to
   6.62%. Per share data and ratios for periods prior to November 30, 2002 have
   not been restated to reflect this change in presentation.
(d)The per share net investment income amount does not reflect the period's
   reclassifications of differences between book and tax basis net investment
   income.
(e)Total return at market value assuming all distributions reinvested at prices
   calculated in accordance with the Dividend Reinvestment Plan.
(f)Had the Investment Advisor not waived or reimbursed a portion of expenses,
   total return would have been reduced.
(g)Not annualized.
(h)The benefits derived from custody credits and directed brokerage
   arrangements, if applicable, had an impact of less than 0.01%, except for
   the year ended November 30, 2004 which had an impact of 0.01% and the year
   ended November 30, 2003 which had an impact of 0.02%.
(i)Ratios reflect average net assets available to common shares only.
(j)Ratios calculated using average net assets including auction preferred
   shares of the Fund, including the effect of custody credits, equals 0.60%,

Shareholder Meeting Results


The annual meeting of shareholders of the Fund was held on May 25, 2005. The
meeting was adjourned with respect to the following proposals: (i) a proposal
to elect two Trustees to be voted on by the holders of Common Shares and
Preferred Shares of the Fund, voting together as a single class; and (ii) a
proposal to elect two Trustees to be voted on by the holders of Preferred
Shares only, voting as a single class. Before the shareholder meeting
reconvened, the Trustees approved a plan of liquidation for the Fund. As a
result, no action on the proposals were taken by shareholders.


                                                                           16

Dividend Reinvestment Plan



Colonial New York Insured Municipal Fund

Pursuant to the Fund's Dividend Reinvestment Plan (the "Plan"), all Common
Shareholders whose shares are registered in their own names will have all
distributions reinvested automatically in additional Common Shares of the Fund
by Computershare (the "Plan Agent"), as agent under the Plan, unless a Common
Shareholder elects to receive cash. An election to receive cash may be revoked
or reinstated at the option of the Common Shareholder. Shareholders whose
shares are held in the name of a broker or nominee will have distributions
reinvested automatically by the broker or nominee in additional shares under
the Plan, unless the service is not provided by the broker or nominee, or
unless the shareholder elects to receive distributions in cash. If the service
is not available, such distributions will be paid in cash. Shareholders whose
shares are held in the name of a broker or nominee should contact the broker or
nominee for details. All distributions to investors who elect not to
participate (or whose broker or nominee elects not to participate) in the Plan
will be paid by check mailed directly to the record holder by the Plan Agent,
as dividend paying agent.

The Plan Agent will furnish each person who buys shares in the offering with
written information relating to the Plan. Included in such information will be
procedures for electing to receive distributions in cash (or, in the case of
shares held in the name of a broker or nominee who does not participate in the
Plan, procedures for having such shares registered in the name of the
shareholder so that such shareholder may participate in the Plan).

If the Trustees of the Fund declare a dividend (including a capital gain
dividend) payable either in shares or in cash, as holders of shares may have
elected, then nonparticipants in the Plan will receive cash and participants in
the Plan will receive the equivalent in shares valued as set forth below.
Whenever a market price is equal to or exceeds net asset value at the time
shares are valued for the purpose of determining the number of shares
equivalent to the distribution, participants will be issued shares at the net
asset value most recently determined as provided under "Net Asset Value" in the
Fund's prospectus and its Statement of Additional Information, but in no event
less than 95% of the market price. If the net asset value of the shares at such
time exceeds the market price of shares at such time, or if the Fund should
declare a dividend (including a capital gain dividend) payable only in cash,
the Plan Agent will, as agent for the participants, use the cash that the
shareholders would have received as a dividend to buy shares in the open
market, the American Stock Exchange or elsewhere, for the participants'
accounts. If, before the Plan Agent has completed its purchases, the market
price exceeds the net asset value of the shares, the average per share purchase
price paid by the Plan Agent may exceed the net asset value of the shares,
resulting in the acquisition of fewer shares than if the dividend (including a
capital gain dividend) had been paid in shares issued by the Fund. The Plan
Agent will apply all cash received as a dividend (including a capital gain
dividend) to purchase shares on the open market as soon as practicable after
the payment date of such dividend, but in no event later than 30 days after
such date, except where necessary to comply with applicable provisions of the
federal securities laws.

There is no charge to participants for reinvesting dividends (including capital
gain dividends). The Plan Agent's fees for handling the reinvestment of
dividends (including capital gain dividends) will be paid by the Fund. There
will be no brokerage charges with respect to shares issued directly by the Fund
as a result of dividends or capital gains distributions payable either in stock
or in cash. However, each participant will pay a pro rata share of brokerage
commissions incurred with respect to the Plan Agent's open market purchases in
connection with the reinvestment of dividends (including capital gain
dividends).

The automatic reinvestment of dividends (including capital gain dividends) will
not relieve participants of any income tax which may be payable on such
dividends. The amount of the dividend for tax purposes may vary depending on
whether the Fund issues new Common Shares or purchases them on the open market.

The Plan may be amended or terminated on 30 days' written notice to Plan
participants. All correspondence concerning the Plan should be directed to
Computershare., by mail at P.O. Box 43010, Providence, RI 02940-3010, or by
phone at 1-800-730-6001.

Board Consideration and Approval of Investment Advisory Agreement


Section 15(c) of the Investment Company Act of 1940 (the "1940 Act") requires
that the Board of Trustees/Directors (the "Board") of the Columbia Funds ("The
Funds"), including a majority of the Trustees and Directors (collectively, the
"Trustees") who are not "interested persons" of the Trusts, as defined in the
1940 Act (the "Independent Trustees"), annually review and approve the terms of
the Funds' investment advisory agreements. At a meeting held on October 13,
2004, the Board reviewed and approved the management contracts ("Advisory
Agreement") with Columbia Management Advisors, Inc. ("CMA") for the Fund.

At meetings held on September 23, 2004 and October 12, 2004, the Advisory Fees
and Expenses Committee (the "Committee") of the Board considered the factors
described below relating to the selection of CMA and the approval of the
Advisory Agreement. At a meeting held on October 13, 2004, the Board, including
the Independent Trustees (who were advised by their independent legal counsel),
considered these factors and reached the conclusions described below.

Nature, Extent and Quality of Services

The Board considered information regarding the nature, extent and quality of
services that CMA provides to the Fund under the Advisory Agreement. CMA
provided the most recent investment adviser registration form ("Form ADV") and
code of ethics for CMA to the Board. The Board reviewed information on the
status of Securities and Exchange Commission ("SEC") and New York Attorney
General ("NYAG") proceedings against CMA and certain of its affiliates,
including the agreement in principle entered into with the SEC and the NYAG on
March 15, 2004 to settle civil complaints filed by the SEC and the NYAG
relating to trading activity in mutual fund shares./1/

The Board evaluated the ability of CMA, including its resources, reputation and
other attributes, to attract and retain highly qualified research, advisory and
supervisory investment professionals. The Board considered information
regarding CMA's compensation program for its personnel involved in the
management of the Fund.

Based on these considerations and other factors, including those referenced
below, the Board concluded that they were generally satisfied with the nature,
extent and quality of the investment advisory services provided to the Fund by
CMA.

Fund Performance and Expenses

CMA provided the Board with relative performance and expense information for
the Fund in a report prepared by Lipper Inc. ("Lipper") an independent provider
of investment company data. The Board considered the total return performance
information, which included the ranking of the Fund within a performance
universe made up of funds with the same Lipper investment classification and
objective (the "Performance Universe") by total return for one-year,
three-year, five-year, ten-year or life of fund periods, as applicable. They
also considered the Fund's performance in comparison to the performance results
of a group (the "Performance Peer Group") of funds selected by Lipper based on
similarities in fund type (e.g. open-end), investment classification and
objective, asset size, load type and 12b-1/service fees and other expense
features, and to the performance results of the Fund's benchmark index. The
Board reviewed a description of Lipper's methodology for selecting the mutual
funds in the Fund's Performance Peer Group and Performance Universe.

The Board considered statistical information regarding the Fund's total
expenses and certain components thereof, including management fees (both actual
management fees based on expenses for advisory and administrative fees
including any reductions for fee waivers and expense reimbursements as well as
contractual management fees that are computed for a hypothetical level of
assets), actual non-management expenses, and fee waivers/caps and expense
reimbursements. They also considered comparisons of these expenses to the
expense information for funds within a group (the "Expense Peer Group")
selected by Lipper based on similarities in fund type (e.g. open-end),
investment classification and objective, asset size, load type and
12b-1/service fees and other expense features (but which, unlike the
Performance Peer Group, may include funds with several different investment
classifications and objectives) and an expense universe ("Expense Universe")
selected by Lipper based on the criteria for determining the Expense Peer Group
other than asset size. The expense information in the Lipper report took into
account all existing fee waivers and expense reimbursements as well as all
voluntary advisory fee reductions applicable to certain Funds that were being
proposed by management in order to reduce the aggregate advisory fees received
from mutual funds advised by CMA and Banc of America Capital Management, LLC
("BACAP") by $32 million per year for five years as contemplated by the
agreement in principle with the NYAG.

The Committee also considered the projected impact on expenses of these Funds
resulting from the overall cost reductions that management anticipated would
result from the proposed shift to a common group of service providers for
transfer agency, fund accounting and custody services for mutual funds advised
by Bank of America affiliates.

The Board also considered information in the Lipper report that ranked each
Fund based on (i) each Fund's one-year performance and actual management fees,
(ii) each Fund's one-year performance and total expenses and (iii) each Fund's
3-year performance and total expenses. Based on these comparisons and expense
and performance rankings of the Fund in the Lipper Report, CMA determined an
overall score for the Fund. The Committee and the Board also considered
projected savings to the Fund that would result from certain modifications in
soft dollar arrangements.

/1/On February 9, 2005, CMA and its affiliate, Columbia Funds Distributor,
   Inc., entered into settlement agreements with the SEC and the NYAG that
   contain substantially the terms outlined in the agreements in principle.

                                                                           18




                                    [GRAPHIC]


Board Consideration and Approval of Investment Advisory Agreement (continued)



The Committee also considered more detailed information relating to certain
Funds, including the Fund, that were highlighted for additional review based
upon the fact that they ranked poorly in terms of overall expense or management
fees, maintained poor performance or demonstrated a combination of below
average to poor performance while maintaining below average or poor expense
rankings. At its September 23, 2004 meeting, the Committee discussed these
Funds with management and in executive session. The Committee requested
additional information from management regarding the cause(s) of the
below-average relative performance of these Funds, any remedial actions
management recommended to improve performance and the general standards for
review of portfolio manager performance. At its October 12, 2004 meeting, the
Committee considered additional information provided by management regarding
these Funds. The Board also considered management's proposal to merge or
liquidate some of these Funds.

Based on these considerations and other factors, the Board concluded that the
overall performance and expense results supported by the approval of the
Advisory Agreements for each Fund.

Investment Advisory Fee Rates

The Board reviewed and considered the proposed contractual investment advisory
fee rates (the "Advisory Agreement Rates") payable by the Funds to CMA for
investment advisory services. In addition, the Board reviewed and considered
the existing and proposed fee waiver and reimbursement arrangements applicable
to the Advisory Agreement Rates and considered the Advisory Agreement Rates
after taking the fee waivers and reimbursements into account (the "Net Advisory
Rates"). At previous meetings, the Committee had separately considered
management's proposal to reduce annual investment advisory fees for certain
Funds under the NYAG agreement in principle and the impact of these reductions
on each affected Fund. Additionally, the Board considered information comparing
the Advisory Agreement Rates and Net Advisory Rates (both on a stand-alone
basis and on a combined basis with the Funds' administration fee rates) with
those of the other funds in the Expense Peer Group. The Board concluded that
the Advisory Agreement Rates and Net Advisory Rates represented reasonable
compensation to CMA, in light of the nature, extent and quality of the services
provided to the Funds, the fees paid and expenses borne by comparable funds and
the costs that CMA incurs in providing these services to the Funds.

Profitability

The Board considered a detailed profitability analysis of CMA based on 2003
financial statements, adjusted to take into account advisory fee reductions
implemented in November 2003 and proposed reductions under the NYAG proposed
settlement. The Board concluded that, in light of the costs of providing
investment management and other services to the Funds, the profits and other
ancillary benefits that CMA and its affiliates received for providing these
services to the Funds were not unreasonable.

Economies of Scale

In evaluating potential economies of scale, the Board considered CMA's proposal
to implement a standardized breakpoint schedule for combined advisory and
administrative fees for the majority of the funds of the same general asset
type within the Columbia Funds complex (other than index and closed-end funds).
The Board noted that the standardization of the breakpoints would not result in
a fee increase for any Fund. The Board concluded that any actual or potential
economies of scale are, or will be, shared fairly with Fund shareholders,
including most particularly through Advisory Agreement Rate breakpoints at
current and reasonably foreseeable asset levels.

Information about Services to Other Clients

In evaluating the proposed fee reductions under the NYAG agreement in
principle, the Board considered information regarding the advisory fee rates
charged by BACAP for the Nations Funds. Members of the Committee and the Board
had also separately reviewed advisory fee rates for variable insurance product
funds advised by CMA. This information assisted the Board in assessing the
reasonableness of fees paid under the Advisory Agreements in light of the
nature, extent and quality of services provided under those agreements.

Other Benefits to CMA

The Board considered information regarding potential "fall-out" or ancillary
benefits received by CMA and its affiliates as a result of their relationship
with the Funds. These benefits could include benefits directly attributable to
the relationship of CMA with the Funds (such as soft dollar credits) and
benefits potentially derived from an increase in the business of CMA as a
result of their relationship with the Funds (such as the ability to market to
shareholders other financial products offered by CMA and its affiliates).

Other Factors and Broader Review

The Board reviews detailed materials provided by CMA annually as part of the
approval process under Section 15(c) of the 1940 Act. The Board also regularly
reviews and assesses the quality of the services that the Funds receive
throughout the year. In this regard, the Board reviews information provided by
CMA at their regular meetings, including, among other things, a detailed
portfolio review, and detailed fund performance reports. In addition, the Board
interviews the heads of each investment area at each regular meeting of the
Board and selected portfolio managers of the Funds at various times throughout
the year. After considering the above-described factors and based on the
deliberations and their evaluation of the information provided to them, the
Board concluded that re-approval of the Advisory Agreements for each of the
Funds was in the best interest of the Funds and their shareholders.
Accordingly, the Board unanimously approved the Advisory Agreements.
