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 integrated various components of Nations Funds, Galaxy Funds and
Columbia Funds, resulting in a single fund family under the Columbia name 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. In
addition to expanding the level of services available to the funds, portfolio
managers and shareholders, we have been able to achieve significant cost
savings for the funds by aggregating our business.

In September, we made major inroads in the initiative to streamline our product
offerings. This included merging several funds and renaming Nations Funds as
Columbia Funds, as well as consolidating the Nations and Columbia web sites.
Over the summer, we completed the service provider consolidation for
shareholder servicing. As we work to complete the remaining product and service
provider consolidations by the end of 2005, we remain committed to building a
mutual fund business that helps you meet, and hopefully exceed, your personal
financial goals. 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 continually earned and
will remain focused on producing results for you. We will continue to strive
for the highest standards of performance and service excellence.

All of these efforts have been undertaken to enable you, as a shareholder, to
benefit from the execution of a consolidated business plan. We believe a more
streamlined fund family with consistent performance and lower fees will provide
the best opportunity for investment growth. We also believe that providing more
robust services to you through multiple channels (Web, phones, voice response)
will be beneficial to 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 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 financial goals on target in the years to come.

Sincerely,

/s/
Christopher L. Wilson

Summary

..  For the six-month period ended September 30, 2005, the fund's class A shares
   returned 1.26%.

..  Four additional short-term interest rate hikes raised yields on money market
   instruments.

..  We believe that the fund's emphasis on floating-rate notes helped the fund
   outperform the average return of its peer group, the Lipper Money Market
   Funds Category.

                 UNDERSTANDING YOUR EXPENSES
                                                      --------------------------
                                     Columbia Money Market Fund

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:

..  For shareholders who receive their account statements from Columbia
   Management Services, Inc., your account balance is available online at
   www.columbiafunds.com or by calling Shareholder Services at 800.345.6611.

..  For shareholders who receive their account statements from their brokerage
   firm, contact your brokerage firm to obtain your account balance.

1.Divide your ending account balance by $1,000. For example, if an account
  balance was $8,600 at the end of the period, the result would be 8.6.

2.In the section of the table below titled "Expenses paid during the period,"
  locate the amount for your share class. You will find this number is in the
  column labeled "actual." Multiply this number by the result from step 1. Your
  answer is an estimate of the expenses you paid on your account during the
  period.

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

Analyzing your fund's expenses by share class

To illustrate these ongoing costs, we have provided an example and calculated
the expenses paid by investors in each share class during the reporting period.
The information in the following table is based on an initial investment of
$1,000, 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 the fund's actual operating expenses and total
return for the period. The amount listed in the "hypothetical" column for each
share class assumes that the return each year is 5% before expenses and
includes the fund's actual expense ratio. You should not use the hypothetical
account values and expenses to estimate either your actual account balance at
the end of the period or the expenses you paid during this reporting period.

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


Expenses paid during the period are equal to the fund's annualized expense
ratio, multiplied by the average account value over the period, then multiplied
by the number of days in the fund's most recent fiscal half-year and divided by
365.
Had the Distributor not waived a portion of Class C share's expenses, Class C
share's total return would have been reduced.
Had the Transfer Agent not waived a portion of expenses, total return would
have been reduced.
It is important to note that the expense amounts shown in the table are meant
to highlight only ongoing costs of investing in the fund and do not reflect any
transactional costs, such as sales charges, redemption or exchange fees.
Therefore, the hypothetical examples provided may not help you determine the
relative total costs of owning shares of different funds. If these
transactional costs were included, your costs would have been higher.

Compare with other funds

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

                      ECONOMIC UPDATE
                                                -----------------------------
                                Columbia Money Market Fund

The US economy moved ahead at a healthy pace during the six-month period that
began April 1, 2005 and ended September 30, 2005. Gross domestic product (GDP)
expanded at an annualized rate of 3.8% as job growth helped sustain consumer
spending and rising profits helped business spending. Employment data was
solid, even in light of Hurricanes Katrina and Rita, which disrupted the labor
market near the end of the period. During the first five months of the period,
the economy added an average of 200,000 new jobs each month. In September,
8,000 jobs were lost as a direct result of the Gulf Coast storms -- a figure
that was lower than originally estimated and considerably lower than expected.
The unemployment rate rose to 5.1%, up from a four-year low of 4.9%.

Energy prices weighed on economic growth during the period. The first signs of
relief came in September as the price of crude oil retreated from a record high
of $69.81 a barrel. Consumer confidence readings dipped in July and August,
then fell sharply in September. The September decline was the largest in 25
years, according to the University of Michigan's monthly survey.

Despite these setbacks, the latest data on the economy suggest that it has
retained momentum. Manufacturing activity remained strong, and business
activity in non-manufacturing industries continued to expand, although the pace
slowed in September. With assistance from insurance funds, federal monies and
charitable contributions, the Gulf region is on track to rebuild, which could
send a positive ripple throughout the national economy.

Bonds delivered modest gains

The US bond market delivered little in the way of price appreciation, but
income resulted in modest positive returns. The yield on the 10-year US
Treasury note, a bellwether for the bond market, ended the period at 4.3%,
slightly lower than where it started the period. In this environment, the
Lehman Brothers Aggregate Bond Index returned 2.31% for the six-month period.
Treasuries outperformed corporate and mortgage-backed securities. However,
high-yield bonds led the fixed income markets despite a setback in the spring
when GM and Ford bonds were downgraded and again as investors appeared to grow
more cautious about risk near the end of the period. The Merrill Lynch US High
Yield, Cash Pay Index returned 3.62%.

Short-term interest rates moved higher

The Federal Reserve Board (the Fed) raised the federal funds rate, a key
short-term rate, from 2.75% to 3.75% in four consecutive one-quarter point
increases. In the wake of Hurricanes Katrina and Rita, some market observers
speculated that the Fed might curtail its rate hikes. However, Fed Chairman
Greenspan indicated that inflation was a greater concern than the
sustainability of economic growth, and we believe that the Fed is likely to
continue to raise short-term interest rates into the first half of 2006.

Despite volatility, stocks moved ahead

The S&P 500 Index -- a broad measure of large company stock market
performance -- returned 5.02% for this reporting period. Small- and mid-cap
stocks outperformed large-cap stocks. Value stocks led growth stocks except
among small caps, where growth gained a small advantage over value. Energy and
utilities stocks outperformed other sectors by a considerable margin.

Summary:
For the six-month period ended September 30, 2005

..  Despite volatility, the broad stock market generated a solid return for the
   period. The S&P 500 Index returned 5.02%. As the economy expanded, small-cap
   stocks outperformed large-cap stocks, as measured by the Russell 2000 Index.

                 PORTFOLIO MANAGER'S REPORT
                                                     --------------------------
                                    Columbia Money Market Fund

For the six-month period ended September 30, 2005, Columbia Money Market Fund
class A shares returned 1.26%. The fund's return was higher than the average
return of its peer group, the Lipper Money Market Funds Category, which was
1.18% for the same period./1/ We believe that the fund's emphasis on
floating-rate debt helped the fund outperform its peer group average.

Portfolio positioning maintained as short-term rates climbed

In managing the fund over the past six months, we have maintained the same
portfolio positioning that we adopted in mid-2004, when the Federal Reserve
Board (the Fed) began its major policy shift to push short-term interest rates
higher. During the most recent six-month period, the Fed raised the federal
funds rate one full percentage point in four equal steps that pushed the
federal funds rate up from 2.75% to 3.75%. The federal funds rate is the rate
member banks charge each other for overnight borrowing to meet reserve
requirements.

The fund's ongoing emphasis on floating-rate debt made sense in a rising-rate
environment, because the coupons on floating-rate notes are reset often and
reflect the Fed's action. Most of the portfolio's floaters were reset relative
to the 1-month or 3-month London Interbank Offering Rate, or LIBOR, while a
small portion were reset relative to the prime rate. Together, these two groups
of floating-rate notes constituted approximately 65% of the portfolio's total
assets.

While emphasizing floating-rate notes, we also sought opportunities to invest
in longer-term fixed-rate paper when we believed that the market had adequately
factored in the effect of future rate hikes by the Fed. Having taken advantage
of several such opportunities in recent months, the fund's weighted average
maturity rose from 30 days at the beginning of the period to 39 days at the end
of the period.

Looking ahead

The Fed has indicated that it will continue to raise short-term interest rates
despite uncertainties in the national economic outlook. Investors hoped that
higher energy prices might constrain the economy and therefore allow the Fed to
end its series of rate hikes. However, the Fed has signaled that higher energy
prices threaten higher inflation, which it has traditionally countered with
higher short-term rates. As always, we plan to monitor the Fed's signals in
order to anticipate any changes in policy that could affect the money markets.

           NOTES TO FINANCIAL STATEMENTS
                                          --------------------------
           September 30, 2005 (Unaudited) Columbia Money Market Fund

Note 1. Organization

Columbia Money Market Fund (the "Fund"), a series of Columbia Funds Trust II
(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 maximum current income consistent with capital preservation and
the maintenance of liquidity.

Fund Shares

The Fund may issue an unlimited number of shares and offers four classes of
shares: Class A, Class B, Class C and Class Z. Each share class has its own
sales charge and expense structure.

Class A shares are sold at net asset value. Class A shares are subject to a
1.00% contingent deferred sales charge ("CDSC") on shares sold within twelve
months on an original purchase of $1 million to $25 million. When exchanged for
Class A shares in another Columbia Fund, a sales charge may be imposed. Class B
shares are subject to a maximum CDSC of 5.00% based upon the holding period
after purchase. Class B shares generally will convert to Class A shares eight
years after purchase, depending on the program under which shares were
purchased. Class C shares are subject to a 1.00% CDSC on shares sold within one
year after purchase. Class Z shares are offered continuously at net asset
value. There are certain restrictions on the purchase of Class Z shares, as
described in the Fund's prospectus.

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

Securities in the Fund are valued utilizing the amortized cost valuation method
permitted in accordance with Rule 2a-7 under the 1940 Act provided certain
conditions are met. This method involves valuing a portfolio security initially
at its cost and thereafter assuming a constant accretion or amortization to
maturity of any discount or premium, respectively.

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

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. Premium and discount are
amortized and accreted, respectively, on all debt securities.

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

                                                                             16



- --------------------------------------------------------------------------------
           September 30, 2005 (Unaudited) Columbia Money Market Fund

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

Dividends from net investment income are declared daily and paid monthly. Net
realized capital gains, if any, are distributed at least annually.

Note 3. Federal Tax Information

The tax character of distributions paid during the years ended March 31, 2005
and March 31, 2004 was as follows:

           September 30, 2005 (Unaudited) Columbia Money Market Fund


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

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.

Management Services, Inc. For its services, the Transfer Agent receives a fee,
paid monthly, at the annual rate of $33.50 per open account. The Transfer Agent
also receives reimbursement for certain out-of-pocket expenses.

For the period from September 1, 2005 through October 31, 2005, the Transfer

attributable to Class B and Class C shares only. The Distributor has
voluntarily agreed to waive a portion of the Class C share distribution fee so
that it will not exceed 0.15%.

The CDSC and the fees received from the Plan are used principally as repayment
to the Distributor for amounts paid by the Distributor to dealers who sold such
shares.

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 Chief
Compliance Officer position. The Fund's fee 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 September 30, 2005, the Fund paid $993 to
Columbia for such services. This amount is included in "Other expenses" on the
Statement of Operations.

Note 5. Shares of Beneficial Interest

As of September 30, 2005, Bank of America and/or its affiliates held 18.5% of
the shares outstanding of the Fund. Subscription and redemption activity of
these accounts may have a significant effect on the operations of the Fund.

Note 6. 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. At September 30, 2005, private insurers who
insured greater than 5% of the total investments of the Fund were as follows:

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 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 Funds' 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 Funds or its shareholders
cannot 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 the 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 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 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, the 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 transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this
litigation on any Fund, if any, cannot 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 alleged 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 Funds and other affiliated
funds participated in securities class action settlements for which the funds
were eligible. Specifically, plaintiffs alleged 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.
Plaintiffs filed a notice of voluntary dismissal of the lawsuit as to all
defendants and all claims without prejudice, which was so-ordered by the judge
on or about November 9, 2005.

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 Funds and 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 (with the
exception of the January 11, 2005 "failure to participate" litigation, which
has been dismissed) 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 Funds.

Note 7. Subsequent Event

On November 18, 2005, the Columbia Money Market Fund merged with Columbia Cash
Reserves.
