                     Dear Shareholder:
                     Investing is a long-term process and we are pleased that
                     you have chosen to include the Columbia family of funds in
                     your overall financial plan.

                     Your financial advisor can help you establish an
                     appropriate investment portfolio and periodically review
                     that portfolio. A well balanced portfolio is one of the
                     keys to successful long-term investing. Your portfolio
                     should be diversified across different asset classes and
                     market segments and your chosen asset allocation should be
                     appropriate for your investment goals, risk tolerance and
                     time horizons.

However, creating an investment strategy is not a one-step process. From time
to time, you'll need to re-evaluate your strategy to determine whether your
investment needs have changed. Most experts recommend giving your portfolio a
"check-up" every year.

As you begin your portfolio check-up, consider whether you have experienced any
major life events since the last time you assessed your portfolio. You may need
to tweak your strategy if you have:

.. Gotten married or divorced
.. Added a child to your family
.. Made a significant change in employment
.. Entered or moved significantly closer to retirement
.. Experienced a serious illness or death in the family
.. Taken on or paid off substantial debt

It's important to remember that over time, performance in different market
segments will fluctuate. When the stock market is up, the bond market is
typically down -- and vice versa. These shifts can cause your portfolio balance
to drift away from your chosen asset allocation. A periodic portfolio check-up
can help make sure your portfolio stays on track. Remember that asset
allocation does not ensure a profit or guarantee against loss.

You'll also want to analyze the individual investments in your portfolio. Of
course, performance should be a key factor in your analysis, but it's not the
only factor to consider. Make sure the investments in your portfolio line up
with your overall objectives and risk tolerance. Be aware of changes in
portfolio management and pay special attention to any funds that have made
significant shifts in their investment strategy.

We hope this information will help you, in working with your financial advisor,
to stay on track to reach your investment goals. Thank you for your business
and for your continued confidence in Columbia Funds.

Sincerely,

/s/ Christopher L. Wilson

Economic Update - Columbia World Equity Fund


  Summary

  For the 12-month period ended March 31, 2007

 . The world's major stock markets moved higher, boosted by generally solid
   economic growth. Foreign markets were generally stronger than the US market,
   as measured by the MSCI EAFE Index.


                                               
                  MSCI World                                         MSCI EAFE
                     Index                                             Index

                                      [GRAPHIC]                                         [GRAPHIC]


                    15.44%                                            20.20%


  The Morgan Stanley Capital International (MSCI) World Index tracks the
  performance of global stocks.
  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.
  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.
World economic growth advanced at a healthy pace during the 12-month period
that began April 1, 2006 and ended March 31, 2007. For 2006, world gross
domestic product was estimated at 3.6%. In 2007, growth is expected to slow
somewhat to 3.0%, primarily because of slower growth in the United States,
where a weak housing market weighed on the economy throughout the period. Core
inflation remained above the comfort level of central banks in most of the
world's major economies, and most central banks raised short-term interest
rates in an effort to control inflationary pressures during the period.

Slower growth for euro zone economies
In the euro zone, the economy expanded 2.75% in 2006, as strong external trade
boosted growth. However, the economy got off to a slower start in 2007, as both
export demand and private consumption showed signs of weakening. The European
Central Bank (ECB) continued to raise its key policy rate in quarter-point
increments throughout the period, reflecting continued concerns about
inflation. Capacity utilization is tight, as many factories are close to their
limits; wages have increased; and money supply growth reached a record high in
January--lending support to the ECB's policy decisions.

Japan's economy loses some momentum
Japan's economy maintained a slow but relatively steady pace of growth
throughout the period. However, it lost momentum in the early months of 2007 as
exports cooled and consumer spending remained weak. Although inflation is
negligible, the Bank of Japan appears set to lift interest rates later this
year. Elsewhere in Asia, the economies of South Korea and Taiwan also showed
signs of slowing as external demand for technology-related exports decelerated
sharply in the final months of 2006.

China continues to expand at record pace
China's economy expanded at an estimated pace of 10.6% in 2006--its fastest
growth in over a decade--despite government-induced monetary and administrative
measures designed to cool the engines of growth. China's export-driven economy
remains vulnerable to slower growth around the globe. Nevertheless, it showed
signs of continued expansion at an impressive pace in the early months of 2007.

World stock markets reflected economic strength
In an environment of generally healthy growth, the world's major stock markets
delivered robust returns. The Morgan Stanley Capital International (MSCI) EAFE
Index, which measures stock market performance in major developed countries
around the world (excluding the United States and Canada), returned 20.20%.
Despite a sharp sell-off in February, most markets regained their forward
momentum and bounced back with significant strength. The MSCI World Index,
which includes the US market, returned 15.44%.

Pass performance is no guarantee of future results.

                                                                             1

The "with sales charge" returns include the maximum initial sales charge of

thereafter for Class B shares and 1.00% for Class C shares for the first year
only. The "without sales charge" returns do not include the effect of sales
charges. If they had, returns would be lower.
Performance results reflect any waivers or reimbursements of fund expenses by
the investment advisor and/or any of its affiliates. Absent these waivers or
reimbursement arrangements, performance results would have been lower.
All results shown assume reinvestment of distributions. Performance for
different share classes will vary based on differences in sales charges and
fees associated with each class.
The table does not reflect the deduction of taxes that a shareholder would pay
on fund distributions or the redemption of fund shares.

Understanding Your Expenses - Columbia World Equity 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 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 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 is
calculated based on the fund's actual operating expenses. 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.

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 transaction costs, such as sales charges, redemption fees or
exchange fees.

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 fund and do not reflect any
transaction costs, such as sales charges, redemption fees 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 transaction
costs were included, your costs would have been higher.

                                                                             3

For the 12-month period that ended March 31, 2007, Columbia World Equity Fund
Class A shares returned 15.11% without sales charge. The fund's benchmark, the
MSCI World Index, returned 15.44%./1/ The average return of funds in the fund's
peer group, the Morningstar World Stock Category, was 13.97% over the same
period./2/ Individual stocks in Japan, Sweden and Germany were largely
responsible for the fund's positive return.

Stock selection was the primary source of performance
Our emphasis on stock selection in companies that we believe should benefit
from global economic growth was instrumental in boosting the fund's total
return. In Japan, performance was enhanced by Canon, Inc., a leader in digital
imaging, and automakers Toyota Motor Corp. and Honda Motor Co., which benefited
from growing concerns about fuel efficiency and the trend toward hybrid
technology. We took profits in Canon, Inc. and Honda Motor Co. when they
reached our target valuations. In Sweden, homebuilder JM AB did well in a
robust housing market. Strong growth in gross domestic product in several
global economies was a factor in the performance of two other stocks in
Sweden--Volvo AB, a manufacturer of trucks and heavy industrial equipment, and
SKF AB, a maker of ball bearings, which are fundamental components of most
industrial processes. Volvo AB was also positively affected by concerns about
controlling automobile emissions, as the company produces some of the best
emission control equipment. In Germany, noteworthy results came from chemical
company BASF AG and steel producer Salzgitter AG, which rose partly because of
higher steel prices. Buoyed by merger and acquisition activity, European
utilities generated returns that were more than double the MSCI World Index
return. Our position in E.ON AG, an integrated power company in Germany, was
helped by this trend.

Approximately half of the fund was invested in the United States, where
retailer Kohl's Corp. rose on solid profit growth. Federated Department Stores
, Inc., also made a positive impact, as the company began to see benefits from
its restructuring program. MEMC Electronic Materials, Inc., figured heavily
into performance. The company produces wafers for the semiconductor and solar
industries. Higher semiconductor prices and growing interest in alternative
energy worked to the company's advantage.

We held a small number of emerging market stocks, including Taiwan
Semiconductor Manufacturing Co., Ltd. and Telefonica O2 Czech Republic AS, both
of which produced positive results. Investments in emerging markets are likely
to remain a very small part of the fund, but we may add positions as
opportunities arise.

Portfolio Managers' Report (continued) - Columbia World Equity Fund



UK consumer discretionary stocks and US financial stocks disappointed
The fund had less exposure than the index to the United Kingdom, which had
strong performance, and the underweight held back results. In addition, one of
the fund's worst performers was UK-based PartyGaming, an on-line gaming company
which suffered because of new legislation that bans US financial institutions
from processing on-line gaming transactions. We sold the stock. US financial
stocks suffered as the rising number of subprime mortgage defaults affected
companies such as AmeriCredit and Radian Group, Inc., which we sold. Our
holdings in Merrill Lynch & Co., Inc., also fell short of our expectations.

Looking ahead
We expect some of the world's equity markets to face some head winds in the
period ahead. In the United States, the pace of economic growth has slowed
because of the Federal Reserve Board's interest-rate hikes, and there are
concerns that the problems in the subprime mortgage market could put additional
pressure on economic growth. Because the United States is a large consumer for
the rest of the world's goods, a significant slowdown in consumer spending
could have negative implications for global growth. In addition, China, another
important market for consumer goods, is looking for ways to slow its economy.
We believe these factors could lead to short-term volatility in the equity
markets. Longer term, however, we think the fundamental backdrop is attractive.
Global growth is relatively high and global monetary policy remains relatively
favorable, creating positive long-term conditions for the equity markets.

Notes to Financial Statements - Columbia World Equity Fund

March 31, 2007

Note 1. Organization
Columbia World Equity Fund (the "Fund"), a series of Columbia Funds Series
Trust I (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 by investing primarily in global equities.

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

Class A shares are subject to a maximum front-end sales charge of 5.75% based
on the amount of initial investment. Class A shares purchased without an
initial sales charge in accounts aggregating $1 million to $50 million at the
time of purchase are subject to a contingent deferred sales charge ("CDSC") of
1.00% if the shares are sold within twelve months of the time of the purchase.
Class B shares are subject to a maximum CDSC of 5.00% based upon the holding
period after purchase. Class B shares will convert to Class A shares eight
years after purchase. Class C shares are subject to a 1.00% CDSC on shares sold
within one year after purchase.

Note 2. Significant Accounting Policies
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.

Forward currency exchange contracts are valued at the prevailing forward
exchange rates 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 4:00 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 that have
quotations which management believes are not appropriate, are valued at fair
value as determined in good faith under consistently applied

22




Columbia World Equity Fund

procedures established by and under the general supervision of the Board of
Trustees.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is evaluating the impact the application of
SFAS 157 will have on the Fund's financial statement disclosures.

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. 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. Although 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
Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy.
The Fund, through its custodian, receives delivery of underlying securities
collateralizing a repurchase agreement. Columbia is responsible for determining
that 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 in the Statement of Operations.

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

                                                                             23




Columbia World Equity Fund

March 31, 2007

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. Net realized capital
gains, if any, are distributed at least annually.

Indemnification
In the normal course of business, the Fund enters into contracts that contain a
variety of representations and warranties and which provide general
indemnities. The Fund's maximum exposure under these arrangements is unknown,
as this would involve future claims against the Fund. Also, under the Fund's
organizational documents and by contract, the trustees and officers of the
Trust are indemnified against certain liabilities that may arise out of their
duties to the Trust. However, based on experience, the Fund expects the risk of
loss due to these representations, warranties and indemnities to be minimal.

Note 3. Federal Tax Information
The timing and character of income and capital gain distributions are
determined in accordance with income tax regulations, which may differ from
GAAP. Reclassifications are made to the Fund's capital accounts for permanent
tax differences to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

For the year ended March 31, 2007, permanent book and tax basis differences
resulting primarily from differing treatments for foreign currency transactions
were identified and reclassified among the components of the Fund's net assets
as follows:




                  Overdistributed Accumulated
                  Net Investment  Net Realized
                  Income          Gain         Paid-In Capital
                                         
                  $(61,793)       $(339,734)   $401,527


Net investment income and net realized gains (losses), as disclosed on the
Statement of Operations, and net assets were not affected by this
reclassification.

The tax character of distributions paid during the years ended March 31, 2007
and March 31, 2006 was as follows:



                                  March 31, 2007 March 31, 2006
                Distributions paid from:
                                           
                Ordinary Income*    $2,012,765      $355,963
                Long-Term Capital
                 Gains               2,637,207            --

*For tax purposes short-term capital gains distributions, if any, are
 considered ordinary income distributions.

As of March 31, 2007, the components of distributable earnings on a tax basis
were as follows:



                   Undistributed Undistributed Net
                   Ordinary      Long-Term     Unrealized
                   Income        Capital Gains Appreciation*
                                         
                   $1,515,270    $3,512,454    $15,077,050

*The differences between book-basis and tax-basis net unrealized
 appreciation/depreciation are primarily due to passive foreign investment
 company mark to market.

Unrealized appreciation and depreciation at March 31, 2007, based on cost of
investments for federal income tax purposes were:



                                             
                    Unrealized appreciation     $15,870,029
                    Unrealized depreciation        (792,979)
                    Net unrealized appreciation $15,077,050


In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109 (the "Interpretation"). This
Interpretation is effective on the last business day of the semiannual
reporting period for fiscal years beginning after December 15,

24




Columbia World Equity Fund

March 31, 2007

2006 and is to be applied to open tax positions upon initial
adoption. This Interpretation prescribes a minimum recognition threshold and
measurement method for the financial statement recognition of tax positions
taken or expected to be taken in a tax return and also requires certain
expanded disclosures. Management is evaluating the application of this
Interpretation to the Fund and has not at this time quantified the impact, if
any, resulting from the adoption of this Interpretation on the Fund's financial
statements.

Note 4. Fees and Compensation Paid to Affiliates

Investment Advisory Fee
Columbia, an indirect, wholly-owned subsidiary of Bank of America Corporation
("BOA"), is the investment advisor to the Fund. Columbia receives a monthly
investment advisory fee based on the Fund's average daily net assets at the
following annual rates:



                    Average Daily Net Assets Annual Fee Rate
                                          
                        First $1 billion     0.40%
                        Over $1 billion      0.35%


For the year ended March 31, 2007, the Fund's effective investment advisory fee
rate was 0.40% of the Fund's average daily net assets.

Administration Fee
Columbia provides administrative and other services to the Fund for a monthly
administration fee at the annual rate of 0.25% of the Fund's average daily net
assets.

Pricing and Bookkeeping Fees
Effective December 15, 2006, the Fund entered into a financial reporting
services agreement with State Street Bank & Trust Company ("State Street") and
Columbia (the "Financial Reporting Services Agreement") pursuant to which State
Street provides financial reporting services to the Fund. Also effective
December 15, 2006, the Fund entered into an accounting services agreement with
State Street and Columbia (collectively with the Financial Reporting Services
Agreement, the "State Street Agreements") pursuant to which State Street
provides accounting services to the Fund. Under the State Street Agreements,
the Fund pays State Street an annual fee of $38,000 paid monthly plus an
additional monthly fee based on an annualized percentage rate of average daily
net assets of the Fund for the month. Under the State Street Agreements, the
combined fee payable to State Street by the Fund will not exceed $140,000
annually. The Fund also reimburses State Street for certain out-of-pocket
expenses.

Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping
Oversight and Services Agreement (the "Services Agreement") with Columbia.
Under the Services Agreement, Columbia provides services related to Fund
expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides
oversight of the accounting and financial reporting services provided by State
Street. Under the Services Agreement, the Fund reimburses Columbia for
out-of-pocket expenses and direct internal costs relating to accounting
oversight and for services related to Fund expenses and the requirements of the
Sarbanes-Oxley Act of 2002.

Prior to December 15, 2006, Columbia was responsible for providing pricing and
bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under its pricing and bookkeeping agreement with the Fund, Columbia was
entitled to receive an annual fee at the rate structure described above under
the State Street Agreements. Under separate agreements between Columbia and
State Street, Columbia delegated certain functions to State Street. As a result
of the delegation, the total fees payable under the pricing and bookkeeping
agreement (other than certain reimbursements paid to Columbia and discussed
below) were paid to State Street. The Fund also reimbursed Columbia and State
Street for out-of-pocket expenses and charges, including fees payable to third
parties for pricing the Fund's portfolio securities and direct internal costs
incurred by Columbia in connection with providing fund accounting oversight and
monitoring and certain other services.

For the year ended March 31, 2007, the effective pricing and bookkeeping fee
rates for the Fund, inclusive of out-of-pocket expenses, was 0.084% of the
Fund's average daily net assets.

Transfer Agent Fee
Columbia Management Services, Inc. (the "Transfer Agent"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, provides shareholder
services to the Fund and has contracted with Boston Financial Data Services

                                                                             25




Columbia World Equity Fund

("BFDS") to serve as sub-transfer agent. The Transfer Agent is entitled to
receive a fee for its services, paid monthly, at the annual rate of $17.00 per
open account plus reimbursement of certain sub-transfer agent fees paid by the
Transfer Agent (exclusive of BFDS fees) calculated based on assets held in
omnibus accounts and intended to recover the cost of payments to other parties
(including affiliates of BOA) for services to those accounts. The Transfer
Agent pays the fees of BFDS for services as sub-transfer agent and is not
entitled to reimbursements for such fees from the Fund. The Transfer Agent may
also retain, as additional compensation for its services, fees for wire,
telephone and redemption orders, IRA trustee agent fees and account transcript
fees due the Transfer Agent from shareholders of the Fund and credits (net of
bank charges) earned with respect to balances in accounts the Transfer Agent
maintains in connection with its services to the Fund. The Transfer Agent also
receives reimbursement for certain out-of-pocket expenses.

For the year ended March 31, 2007, the Fund's effective transfer agent fee
rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was
0.23% of the Fund's average daily net assets.

Underwriting Discounts, Service and Distribution Fees
Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal
underwriter of the Fund. For the year ended March 31, 2007, the Distributor has
retained net underwriting discounts of $30,912 on sales of the Fund's Class A
shares and net CDSC fees of $201, $15,816 and $520 on Class A, Class B and
Class C share redemptions, respectively.

The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of
a monthly service fee to the Distributor at the annual rate of 0.25% of the
average daily net assets attributable to Class A, Class B and Class C shares of
the Fund. The Plan also requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.75% of the average daily net assets
attributable to Class B and Class C shares only. This arrangement may be
modified or terminated by the distributor at any time.

The CDSC and the distribution 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 in 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
All officers of the Fund are employees of Columbia or its affiliates and, with
the exception of the Fund's Chief Compliance Officer, receive no compensation
from the Fund. The Board of Trustees has appointed a Chief Compliance Officer
to the Fund in accordance with federal securities regulations. The Fund, along
with other affiliated funds, pays its pro-rata share of the expenses associated
with the Chief Compliance Officer. The Fund's expenses for 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 the requirements of
the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund
paid $2,875 to Columbia for such services. This amount is included in "Other
expenses" in the Statement of Operations.

Note 5. Portfolio Information
For the year ended March 31, 2007, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $80,751,487 and
$93,898,499, respectively.

Note 6. Shares of Beneficial Interest
As of March 31, 2007, one shareholder held 5.1% of the shares outstanding.
Subscription and redemption activity of this account may have a significant
effect on the operations of the Fund.

Note 7. Line of Credit
The Trust and other affiliated funds participate in a $350,000,000 committed
unsecured revolving line of credit and

26




Columbia World Equity Fund

March 31, 2007

a $150,000,000 uncommitted, unsecured line of credit, both provided by State
Street. Borrowings are available for temporary or emergency purposes.

Interest on the committed line of credit is charged to each participating fund
based on the fund's borrowings at a rate per annum equal to the Federal Funds
Rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued
and apportioned among the participating funds based on their pro-rata portion
of the unutilized committed line of credit. Interest on the uncommitted line of
credit is charged to each participating fund based on the fund's borrowings at
a variable rate per annum equal to the Federal Funds Rate plus a spread, as
determined and quoted by State Street at the time of the request for a loan. A
one-time structuring fee of $30,000 is also accrued and apportioned to each
fund participating in the uncommitted line of credit based on the average net
assets of the participating funds. In addition, if the uncommitted line of
credit is extended for an additional period, an annual administration fee of
$15,000 will be charged and apportioned among the participating fund. The
commitment fee and structuring fee are included in "Other expenses" in the
Statement of Operations.

For the year ended March 31, 2007, the Fund did not borrow under this
arrangement.

Note 8. Redemption Fees
The Fund imposes a 2.00% redemption fee to shareholders of the Fund who redeem
shares within 60 days of purchase. Redemption fees, which are retained by the
Fund, are accounted for as an addition to paid-in capital and are allocated to
each class proportionately for purposes of determining the net asset value of
each class. For the year ended March 31, 2007, the redemption fees for the
Class A, Class B, and Class C shares of the Fund amounted to $1,079, $135, and
$17, respectively.

Note 9. 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.

Sector Focus
Companies that are in different but closely related industries are sometimes
described as being in the same sector. Although the Fund does not intend to
focus on any particular sector, at times the Fund may have a large portion of
its assets invested in a particular sector. During such times, the Fund will
have greater exposure to the economic and market events affecting such sector
than if it were more broadly invested across multiple sectors.

Legal Proceedings
On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged
into Banc of America Capital Management, LLC (now named Columbia Management
Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has
been renamed Columbia Management Distributors, Inc.) (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") on matters
relating to mutual fund trading. The SEC Order and the NYAG Settlement are
referred to collectively as the "Settlements".

Under the terms of the SEC Order, the Columbia Group 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

                                                                             27




Columbia World Equity Fund

March 31, 2007

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 to reduce
management fees for certain Columbia Funds (including the former Nations Funds)
and other mutual funds 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 that was developed by an independent distribution consultant
and approved by the SEC on April 6, 2007.

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 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.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation
transferred these cases and cases against other mutual fund companies based on
similar allegations to the United States District Court in Maryland for
consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently,
additional related cases were transferred to the MDL. On September 29, 2004,
the plaintiffs in the MDL filed amended and consolidated complaints. One of
these amended complaints is a putative class action that includes claims under
the federal securities laws and state common law, and that names Columbia, the
Distributor, the Trustees of the Columbia Funds, Bank of America Corporation
and others as defendants. Another of the amended complaints is a derivative
action purportedly on behalf of the Columbia Funds that asserts claims under
federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss
the claims in the pending cases. On March 1, 2006, for reasons stated in the
court's memoranda dated November 3, 2005, the U.S. District Court for the
District of Maryland granted in part and denied in part the defendants' motions
to dismiss. The court dismissed all of the class action claims pending against
the Columbia Funds Trusts. As to Columbia and the Distributor, the claims under
the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the
Investment Company Act of 1940 ("ICA") and the state law claims were dismissed.
The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of
1934 and claims under Section 36(b) of the ICA were not dismissed.

On March 21, 2005, a purported class action was filed in Massachusetts state
court alleging that certain conduct, including market timing, entitled Class B
shareholders in certain Columbia funds to an exemption from contingent deferred
sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was
removed to federal court in Massachusetts and the federal Judicial Panel
transferred the CDSC Lawsuit to the MDL.

On April 4, 2006, the plaintiffs and the Columbia defendants named in the MDL,
including the Columbia Funds, entered into a term sheet containing the
principal terms of a stipulation of settlement that would settle all
Columbia-related claims in the MDL described above, including the CDSC Lawsuit.
On April 6, 2006, the U.S. District Court for the District of Maryland stayed
all actions with respect to these Columbia-related claims. The settlement is
subject to court approval.

In 2004, the Columbia Funds' adviser and distributor and certain affiliated
entities and individuals 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.
Certain Columbia Funds were named as nominal defendants. 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 purposes. 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. On November 30, 2005, the judge dismissed all claims by
plaintiffs and entered final judgment in favor of the defendants. The
plaintiffs appealed to the United States Court of Appeals for the First Circuit
on December 30, 2005. A stipulation and settlement agreement dated January 19,
2007 was filed in the First Circuit on February 14, 2007, with a joint
stipulation of dismissal and

28




Columbia World Equity Fund

March 31, 2007

motion for remand to obtain district court approval of the settlement. That
joint motion was granted and the appeal was dismissed. On March 6, 2007, the
case was remanded to the District Court. On May 11, 2007, the District Court
entered a preliminary approval order which granted preliminary approval of the
settlement. A final settlement hearing, at which the District Court will
determine whether the proposed settlement should be finally approved and the
action dismissed on the merits with prejudice, is scheduled for September 18,
2007. The terms of the settlement, if finally approved, will require payments
by the funds' adviser and/or its affiliates, including payment of plaintiffs'
attorneys' fees and notice to class members. In the event that the settlement
is not finally approved, the plaintiffs may elect to go forward with their
appeal and no opinion is expressed regarding the likely outcome or financial
impact of such an appeal on any fund.

                                                                             29




Report of Independent Registered Public Accounting Firm


To the Trustees of Columbia Funds Series Trust I and the Shareholders of
Columbia World Equity Fund

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Columbia World Equity Fund (the
"Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and the
results of its operations, the changes in its net assets and the financial
highlights for the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management. Our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at March 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Board Consideration and Approval of Investment Advisory Agreements

The Advisory Fees and Expenses Committee of the Board of Trustees meets one or
more times annually to review the advisory agreements (collectively, the
"Agreements") of the funds for which the Trustees serve as trustees (each a
"fund") and determine whether to recommend that the full Board approve the
continuation of the Agreements for an additional one-year period. After the
Committee has made its recommendation, the full Board, including the
Independent Trustees, determines whether to approve the continuation of the
Agreements. In addition, the Board, including the Independent Trustees,
considers matters bearing on the Agreements at most of its other meetings
throughout the year and meets regularly with the heads of each investment area
within Columbia. Through the Board's Investment Oversight Committees, Trustees
also meet with selected fund portfolio managers at various times throughout the
year.

The Trustees receive and review all materials that they, their legal counsel or
Columbia, the funds' investment adviser, believe to be reasonably necessary for
the Trustees to evaluate the Agreements and determine whether to approve the
continuation of the Agreements. Those materials generally include, among other
items, (i) information on the investment performance of each fund relative to
the performance of peer groups of mutual funds and the fund's performance
benchmarks, (ii) information on each fund's advisory fees and other expenses,
including information comparing the fund's expenses to those of peer groups of
mutual funds and information about any applicable expense caps and fee
"breakpoints," (iii) information about the profitability of the Agreements to
Columbia, including potential "fall-out" or ancillary benefits that Columbia
and its affiliates may receive as a result of their relationships with the
funds and (iv) information obtained through Columbia's response to a
questionnaire prepared at the request of the Trustees by counsel to the funds
and independent legal counsel to the Independent Trustees. The Trustees also
consider other information such as (v) Columbia's financial results and
financial condition, (vi) each fund's investment objective and strategies and
the size, education and experience of Columbia's investment staffs and their
use of technology, external research and trading cost measurement tools, (vii)
the allocation of the funds' brokerage, if any, and the use of "soft"
commission dollars to pay for research products and services, (viii) Columbia's
resources devoted to, and its record of compliance with, the funds' investment
policies and restrictions, policies on personal securities transactions and
other compliance policies, (ix) Columbia's response to various legal and
regulatory proceedings since 2003 and (x) the economic outlook generally and
for the mutual fund industry in particular. In addition, the Advisory Fees and
Expenses Committee confers with the funds' independent fee consultant and
reviews materials relating to the funds' relationships with Columbia provided
by the independent fee consultant. Throughout the process, the Trustees have
the opportunity to ask questions of and request additional materials from
Columbia and to consult with independent legal counsel to the Independent
Trustees and the independent fee consultant.

The Board of Trustees most recently approved the continuation of the Agreements
at its October, 2006 meeting, following meetings of the Advisory Fees and
Expenses Committee held in August, September and October, 2006. In considering
whether to approve the continuation of the Agreements, the Trustees, including
the Independent Trustees, did not identify any single factor as determinative,
and each weighed various factors as he or she deemed appropriate. The Trustees
considered the following matters in connection with their approval of the
continuation of the Agreements:

The nature, extent and quality of the services provided to the funds under the
Agreements. The Trustees considered the nature, extent and quality of the
services provided by Columbia and its affiliates to the funds and the resources
dedicated to the funds by Columbia and its affiliates. Among other things, the
Trustees considered (i) Columbia's ability (including its personnel and other
resources, compensation programs for personnel involved in fund management,
reputation and other attributes) to attract and retain highly qualified
research, advisory and supervisory investment professionals; (ii) the portfolio
management services provided by those investment professionals; and (iii) the
trade execution services provided on behalf of the funds. For each fund, the
Trustees also considered the benefits to shareholders of investing in a mutual
fund that is part of a family of funds offering exposure to a variety of asset
classes and investment disciplines and providing a variety of fund and
shareholder services. After reviewing those and related factors, the Trustees
concluded, within the context of their overall conclusions regarding each of
the Agreements, that the nature, extent and quality of services provided
supported the continuation of the Agreements.

Investment performance of the funds and Columbia. The Trustees reviewed
information about the performance of each fund over various time periods,
including information prepared by an independent third party that compared the
performance of each fund to the performance of peer groups of mutual funds and
performance benchmarks. The Trustees also reviewed a description of the third
party's methodology for identifying each fund's peer group for purposes of
performance and expense comparisons. The Trustees also considered additional
information that the Advisory Fees and Expenses Committee requested from
Columbia relating to funds that presented relatively weaker performance and/or
relatively higher expenses.

In the case of each fund whose performance lagged that of a relevant peer group
for certain (although not necessarily all) periods, the Trustees concluded that
other factors relevant to performance were sufficient, in light of other
considerations, to warrant continuation of the fund's Agreements. Those factors
varied from fund to fund, but included one or more of the following: (i) that
the fund's performance, although lagging in certain recent periods, was
stronger over the longer term; (ii) that the underperformance was attributable,
to a significant extent, to investment decisions that were reasonable and
consistent with the fund's investment strategy and policies and that the fund
was performing as expected, given these investment decisions, market conditions
and the fund's investment strategy; (iii) that the fund's performance was
competitive when compared to other relevant performance benchmarks or peer
groups; (iv) that Columbia had taken or was taking steps designed to help
improve the fund's investment performance, including, but not limited to,
replacing portfolio managers or modifying investment strategies; and (v) that
the fund was proposed to be reorganized into another fund, and that such
reorganization would result in a reduction in fund expenses.

The Trustees also considered Columbia's performance and reputation generally,
the funds' performance as a fund family generally, and Columbia's historical
responsiveness to Trustee concerns about performance and Columbia's willingness
to take steps intended to improve performance.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
performance of each fund and Columbia was sufficient, in light of other
considerations, to warrant the continuation of the Agreement(s) pertaining to
that fund.

The costs of the services provided and profits realized by Columbia and its
affiliates from their relationships with the funds. The Trustees considered the
fees charged to the funds for advisory services as well as the total expense
levels of the funds. That information included comparisons (provided by
management and by an independent third party) of each fund's advisory fees and
total expense levels to those of the fund's peer groups and information about
the advisory fees charged by Columbia to comparable institutional accounts. In
considering the fees charged to those accounts, the Trustees took into account,
among other things, management's representations about the differences between
managing mutual funds as compared to other types of accounts, including
differences in the services provided, differences in the risk profile of such
business for Columbia, and the additional resources required to manage mutual
funds effectively. In evaluating each fund's advisory fees, the Trustees also
took into account the demands, complexity and quality of the investment
management of the fund. The Trustees considered existing advisory fee
breakpoints, and Columbia's use of advisory fee waivers and expense caps, which
benefited a number of the funds. The Trustees also noted management's stated
justification for the fees charged to the funds, which included information
about the investment performance of the funds and the services provided to the
funds. The Trustees also considered the compensation directly or indirectly
received by Columbia and its affiliates from their relationships with the
funds. The Trustees reviewed information provided by management as to the
profitability to Columbia and its affiliates of their relationships with each
fund, and information about the allocation of expenses used to calculate
profitability. When reviewing profitability, the Trustees also considered court
cases in which adviser profitability was an issue in whole or in part, the
performance of the relevant funds, the expense level of each fund, and whether
Columbia had implemented breakpoints and/or expense caps with respect to the
fund.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
advisory fees charged to each fund, and the related profitability to Columbia
and its affiliates of their relationships with the fund, supported the
continuation of the Agreement(s) pertaining to that fund.

                                                                             37







Economies of Scale. The Trustees considered the existence of any economies of
scale in the provision by Columbia of services to each fund, to groups of
related funds, and to Columbia's investment advisory clients as a whole and
whether those economies were shared with the funds through breakpoints in the
investment advisory fees or other means, such as expense waivers/reductions and
additional investments by Columbia in investment, trading and compliance
resources. The Trustees noted that many of the funds benefited from
breakpoints, expense caps, or both. In considering those issues, the Trustees
also took note of the costs of the services provided (both on an absolute and a
relative basis) and the profitability to Columbia and its affiliates of their
relationships with the funds, as discussed above.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
extent to which economies of scale were shared with the funds supported the
continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but
were not limited to the following:

.. the extent to which each fund had operated in accordance with its investment
  objective and investment restrictions, the nature and scope of the compliance
  programs of the funds and Columbia and the compliance-related resources that
  Columbia and its affiliates were providing to the funds;

.. the nature, quality, cost and extent of administrative and shareholder
  services performed by Columbia and its affiliates, both under the Agreements
  and under separate agreements for the provision of transfer agency and
  administrative services;

.. so-called "fall-out benefits" to Columbia and its affiliates, such as the
  engagement of its affiliates to provide distribution, brokerage and transfer
  agency services to the funds, and the benefits of research made available to
  Columbia by reason of brokerage commissions generated by the funds'
  securities transactions, as well as possible conflicts of interest associated
  with those fall-out and other benefits, and the reporting, disclosure and
  other processes in place to disclose and monitor those possible conflicts of
  interest; and

.. the draft report provided by the funds' independent fee consultant, which
  included information about and analysis of the funds' fees, expenses and
  performance.

Based on their evaluation of all factors that they deemed to be material,
including those factors described above, and assisted by the advice of
independent counsel and the independent fee consultant, the Trustees, including
the Independent Trustees, approved the continuance of each of the Agreements
through October 31, 2007.

Summary of Management Fee Evaluation by Independent Fee Consultant

Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between
the Office of Attorney General of New York State and Columbia Management
Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006

  I. Overview

Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors,
Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's
Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates
that CMA may manage or advise a Columbia Fund ("Fund" and together with all
such funds or a group of such funds as the "Funds") only if the Independent
Members of the Fund's Board of Trustees (such Independent Members of the Fund's
Board together with the other members of the Fund's Board, referred to as the
"Trustees") appoint a Senior Officer or retain an Independent Fee Consultant
("IFC") who is to manage the process by which proposed management fees are
negotiated. The AOD further stipulates that the Senior Officer or IFC is to
prepare a written annual evaluation of the fee negotiation process.

On September 14, 2006, the Independent Members of the Funds' Boards retained me
as IFC for the Funds. In this capacity, I have prepared the second annual
written evaluation of the fee negotiation process. I am successor to the first
IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed
to the second annual written evaluation until his resignation as IFC in August
2006 to become Director of the Division of Market Regulation at the U.S.
Securities and Exchange Commission./2/

A. Role of the Independent Fee Consultant
The AOD charges the IFC with "managing the process by which proposed management
fees...to be charged the Columbia Fund are negotiated so that they are
negotiated in a manner which is at arms' length and reasonable and consistent
with this Assurance of Discontinuance." In this role, the IFC does not replace
the Trustees in negotiating management fees with CMA, and the IFC does not
substitute his or her judgment for that of the Trustees about the
reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a
Columbia Fund only if the reasonableness of the proposed management fees is
determined by the Board of Trustees...using...an annual independent written
evaluation prepared by or under the direction of...the Independent Fee
Consultant."

B. Elements Involved in Managing the Fee Negotiation Process
Managing the fee negotiation process has three elements. One involves reviewing
the information provided by CMG to the Trustees for evaluating the proposed
management fees and augmenting that information, as necessary, with additional
information from CMG or other sources and with further analyses of the
information and data. The second element involves reviewing the information and
analysis relative to at least the following six factors set forth in the AOD:

1.The nature and quality of CMA's services, including the Fund's performance;

2.Management fees (including any components thereof) charged by other mutual
  fund companies for like services;

3.Possible economies of scale as the Fund grows larger;

4.Management fees (including any components thereof) charged to institutional
  and other clients of CMA for like services;

5.Costs to CMA and its affiliates of supplying services pursuant to the
  management fee agreements, excluding any intra-corporate profit; and

6.Profit margins of CMA and its affiliates from supplying such services.

1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which
 also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds'
 transfer agent. Before the date of this report, CMA merged into an affiliated
 entity, Banc of America Capital Management, LLC, which was renamed Columbia
 Management Advisors, LLC and which carries on the business of CMA. CFD also
 has been renamed Columbia Management Distributors, Inc.
2I am an independent economic consultant. From August 2005 until August 2006, I
 provided support to Mr. Sirri as an independent consultant. From 1994 to 2004,
 I was Chief Economist at the Investment Company Institute. Earlier, I was
 Section Chief and Assistant Director at the Federal Reserve Board and
 Professor of Economics at Oklahoma State University. I have no material
 relationship with Bank of America or CMG, aside from serving as IFC, and I am
 aware of no material relationship with any of their affiliates. To assist me
 with the report, I engaged NERA Economic Consulting, an independent consulting
 firm that has had extensive experience in the mutual fund industry. I also
 have retained Willkie Farr & Gallagher LLP as counsel to advise me in
 connection with the report.

                                                                             39







The final element involves providing the Trustees with a written evaluation of
the above factors as they relate to the fee negotiation process.

C. Organization of the Annual Evaluation
The 2006 annual evaluation focuses on the six factors and contains a section
for each factor except that CMA's costs and profits from managing the Funds
have been combined into a single section. In each section, the discussion of
the factor considers and analyzes the available data and other information as
they bear upon the fee negotiation process. If appropriate, the discussion in
the section may point out certain aspects of the proposed fees that may warrant
particular attention from the Trustees. The discussion also may suggest other
data, information, and approaches that the Trustees might consider
incorporating into the fee negotiation process in future years.

In addition to a discussion of the six factors, the report reviews the status
of recommendations made in the 2005 IFC evaluation. The 2006 report also
summarizes the findings with regard to the six factors and contains a summary
of recommendations for possible enhancements to the process.

  II. Status of 2005 Recommendations

The 2005 IFC evaluation contains recommendations aimed at enhancing the
evaluation of proposed management fees by Trustees. The section summarizes
those recommendations and includes my assessment of the response to the
recommendations.

1.  Recommendation: Trustees should consider requesting more analytical work
    from CMG in the preparation of future 15(c) materials.

    Status: CMG has provided additional analyses to the Trustees on economies
    of scale, a comparative analysis of institutional and retail management
    fees, management fee breakpoints, risk-adjusted performance, fee waivers
    and expense reimbursements, and CMG's costs and profitability.

2.  Recommendation: Trustees may wish to consider whether CMG should continue
    expanding the use of Morningstar or other third party data to supplement
    CMG's fee and performance analysis that is now based primarily on Lipper
    reports.

    Status: CMG has used data from Morningstar Inc. to compare with data from
    Lipper Inc. ("Lipper") in performing the Trustees' screening procedures.

3.  Recommendation: Trustees should consider whether...the fund-by-fund
    screen...should place comparable emphasis on both basis point and quintile
    information in their evaluation of the funds...Also, the Trustees should
    consider incorporating sequences of one year performance into a
    fund-by-fund screen.

    Status: CMG has not provided Trustees with results of the screening process
    using percentiles. CMG has provided Trustees with information on the
    changes in performance and expenses between 2005 and 2006 and data on
    one-year returns.

4.  Recommendation: Given the volatility of fund performance, the Trustees may
    want to consider whether a better method exists than th[e] fee waiver
    process to deal with fund underperformance.

    Status: It is my understanding that the Trustees have determined to address
    fund underperformance not only through fee waivers and expense caps but
    also through discussions with CMG regarding the sources of
    underperformance. CMG has provided Trustees with an analysis of the
    relationship between breakpoints, expense reimbursements, and fee waivers.

5.  Recommendation: [Seventy-one] percent of funds [have] yet to reach their
    first management fee breakpoint... Trustees may wish to consider whether
    the results of my ongoing economies-of-scale work affects the underlying
    economic assumptions reflected in the existing breakpoint schedules.

    Status: CMG has prepared a memo for the Trustees discussing its views on
    the nature and sharing of potential economies of scale. The memo discuses
    CMG's view that economies of scale arise at the complex level rather than
    the fund level. The memo also describes steps, including the introduction
    of breakpoints, taken to share economies of scale with shareholders. CMG's
    analysis, however, does not discuss specific sources of economies of scale
    and does not link breakpoints to economies of scale that might be realized
    as the Funds' assets increase.

40







6.  Recommendation: Trustees should continue working with management to address
    issues of funds that demonstrate consistent or significant underperformance
    even if the fee levels for the funds are low.

    Status: Trustees monitor performance on an ongoing basis.

  III. Findings

A. General
1.  Based upon my examination of the available information and the six factors,
    I conclude that the Trustees have the relevant information necessary to
    evaluate the reasonableness of the proposed management fees for the Funds.
    CMG has provided the Trustees with relevant materials on the six factors
    through the 15(c) contract renewal process and in materials prepared for
    review at Board and Committee meetings.

2.  In my view, the process by which the proposed management fees of the Funds
    have been negotiated in 2006 thus far has been, to the extent practicable,
    at arms' length and reasonable and consistent with the AOD.

B. Nature and Quality of Services, Including Performance
3.  The performance of the Funds has been relatively strong, especially that of
    fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance
    periods, over 60 percent of the funds have ranked in the top three
    performance quintiles.

4.  The performance of the equity Funds overall, though less concentrated in
    the top two quintiles than the fixed income Funds, improved in 2006
    relative to that in 2005. The fixed-income funds maintained the relatively
    high performance level of 2005 in 2006.

5.  The Funds' overall performance adjusted for risk was significantly stronger
    than performance unadjusted for risk. Domestic and international equity
    funds, in particular, moved to higher relative performance rankings after
    adjusting for risk.

6.  The procedure used to construct the performance universe in which each
    Fund's performance is ranked relative to comparable funds may bias a Fund's
    ranking upward within that universe. The bias occurs because the
    performance ranking procedure includes all share classes of multi-class
    funds in the universe and because the procedure ranks either no-load or A
    share classes of the Funds. No-load and A share classes generally have
    lower total expenses than B and C shares (owing to B and C shares having
    higher distribution/service fees) and thus, given all else, would
    outperform many of B and C share classes included in the universe. A
    preliminary analysis that adjusts for the bias results in a downward
    movement in the relative performance for the Funds but does not change the
    general finding that the Funds' performance has been strong relative to
    comparable funds.

C. Management Fees Charged by Other Mutual Fund Companies
7.  The Funds' management fees and total expenses are generally low relative to
    those of their peers. At least 56 percent of the Funds are in the first or
    second quintiles with the lowest fees and expenses and nearly three fourths
    or more in the first three quintiles. Equity Funds are more highly
    concentrated in the first three quintiles than fixed-income Funds.

8.  The fee and expense rankings as whole are similar to those in 2005 in that
    the majority of funds are ranked in the top quintiles. Nonetheless, a
    number of individual funds experienced a change in ranking between 2005 and
    2006. This fund-level instability may reflect sensitivity of rankings to
    the composition of the comparison groups, as the membership of the peer
    groups typically changed substantially between the two years.

9.  The Liberty Money Market Fund VS appears to have a higher management fee
    structure than that of other Columbia money market funds of comparable
    asset size.

                                                                             41







D. Trustees' Fee and Performance Evaluation Process
10. The Trustees' evaluation process identified 21 funds in 2006 for further
    review based upon their relative performance or expenses. Seventeen of
    these funds had been subject to review in 2004 or 2005.

E. Potential Economies of Scale
11. CMG has prepared a memo for the Trustees containing its views on the
    sources and sharing of potential economies of scale. CMG views economies of
    scale as arising at the complex level and would regard estimates of scale
    economies for individual funds as unreliable. CMG has not, however,
    identified specific sources of economies of scale nor has it provided any
    estimates of the magnitude of any economies of scale. In the memo, CMG also
    describes measures taken by the Trustees and CMG that seek to share any
    potential economies of scale through breakpoints in management fee
    schedules, expense reimbursements, fee waivers, enhanced shareholder
    services, fund mergers, and operational consolidation. These measures,
    although of significant benefit to shareholders, have not been directly
    linked in the memo to the existence, sources, and magnitude of economies of
    scale.

F. Management Fees Charged to Institutional Clients
12. CMG has provided Trustees with comparisons of mutual fund management fees
    and institutional fees based upon standardized fee schedules and upon
    actual fees. Based upon the information, institutional fees are generally
    lower than the Funds' management fees. This pattern is consistent with the
    economics of the two financial products. Data are not available, however,
    on actual institutional fees at other money managers. Thus, it is not
    possible to determine the extent to which differences between the Funds'
    management fees and institutional fees are consistent with those seen
    generally in the marketplace.

G. Revenues, Expenses, and Profits
13. The financial statements and the methodology underlying their construction
    generally form a sufficient basis for Trustees to evaluate the expenses and
    profitability of the Funds.

  IV. Recommendations

A. Performance
1.  Trustees may wish to consider incorporating risk adjusted measures in their
    evaluation of performance. CMG has begun to prepare reports for the
    Trustees with risk adjustments, which could form the basis for formally
    including the measures in the 15(c) materials. To this end, Trustees may
    wish to have CMG prepare documents explaining risk adjustments and
    describing their advantages and disadvantages.

2.  Trustees may wish to consider having CMG evaluate the sensitivity of
    performance rankings to the design of the universe. The preliminary
    analysis contained in the evaluation suggests that the method employed by
    Lipper, the source of performance rankings used by the Trustees, may bias
    performance rankings upward.

B. Economies of Scale
3.  Trustees may wish to consider having CMG extend its analysis of economies
    of scale by examining the sources of such economies, if any. Identification
    of the sources may enable the Trustees and CMG to gauge their magnitude. It
    also may enable the Trustees and CMG to build upon past work on
    standardized fee schedules so that the schedules themselves are consistent
    with any economies of scale and their sources. Finally, an extension of the
    analysis may enable the Trustees and CMG to develop a framework that
    coordinates the use of fee waivers and expense caps with the standard fee
    schedules and with any economies of scale and their sources.

C. Institutional Fees
4.  Trustees may wish to consider encouraging CMG to build further upon its
    expanded analysis of institutional fees by refining the matching of
    institutional accounts with mutual funds, by dating the establishment of
    each institutional account, and by incorporating other accounts, such as
    subadvisory relationships, trusts, offshore funds, and separately managed
    accounts into the analysis.

42







D. Profitability
5.  Trustees may wish to consider requesting that CMG expand the reporting of
    revenues and expenses to include more line-item detail for management and
    administration, transfer agency, fund accounting, and distribution.

6.  Trustees may wish to consider requesting that CMG provide a statement of
    its operations in the 15(c) materials.

7.  Trustees may wish to consider the treatment of the revenue sharing with the
    Private Bank of Bank of America in their review of CMG's profitability.

Respectfully submitted,
John D. Rea

                                                                             43




Appendix


Sources of Information Used in the Evaluation

The following list generally describes the sources and types of information
that were used in preparing this report.

1.  Performance, management fees, and expense ratios for the Funds and
    comparable funds from other fund complexes from Lipper and CMG. The sources
    of this information were CMG and Lipper;

2.  CMG's expenses and profitability obtained directly from CMG;

3.  Information on CMG's organizational structure;

4.  Profitability of publicly traded asset managers from Lipper;

5.  Interviews with CMG staff, including members of senior management, legal
    staff, heads of affiliates, portfolio managers, and financial personnel;

6.  Documents prepared by CMG for Section 15(c) contract renewals in 2005 and
    2006;

7.  Academic research papers, industry publications, professional materials on
    mutual fund operations and profitability, and SEC releases and studies of
    mutual fund expenses

8.  Interviews with and documents prepared by Ernst & Young LLP in its review
    of the Private Bank Revenue Sharing Agreement;

9.  Discussions with Trustees and attendance at Board and committee meetings
    during which matters pertaining to the evaluation were considered.

In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data
management and analysis. NERA has extensive experience in the mutual fund
industry that provides unique insights and special knowledge pertaining to my
independent analysis of fees, performance, and profitability. I have also
retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher
LLP as outside counsel to advise me in connection with my evaluation.

Finally, meetings and discussions with CMG staff were informative. My
participation in Board and committee meetings in which Trustees and CMG
management discussed issues relating to management contracts were of great
benefit to the preparation of the evaluation.

                     Dear Shareholder:
                     Investing is a long-term process and we are pleased that
                     you have chosen to include the Columbia family of funds in
                     your overall financial plan.

                     Your financial advisor can help you establish an
                     appropriate investment portfolio and periodically review
                     that portfolio. A well balanced portfolio is one of the
                     keys to successful long-term investing. Your portfolio
                     should be diversified across different asset classes and
                     market segments and your chosen asset allocation should be
                     appropriate for your investment goals, risk tolerance and
                     time horizons.

However, creating an investment strategy is not a one-step process. From time
to time, you'll need to re-evaluate your strategy to determine whether your
investment needs have changed. Most experts recommend giving your portfolio a
"check-up" every year.

As you begin your portfolio check-up, consider whether you have experienced any
major life events since the last time you assessed your portfolio. You may need
to tweak your strategy if you have:

.. Gotten married or divorced
.. Added a child to your family
.. Made a significant change in employment
.. Entered or moved significantly closer to retirement
.. Experienced a serious illness or death in the family
.. Taken on or paid off substantial debt

It's important to remember that over time, performance in different market
segments will fluctuate. These shifts can cause your portfolio balance to drift
away from your chosen asset allocation. A periodic portfolio check-up can help
make sure your portfolio stays on track. Remember that asset allocation does
not ensure a profit or guarantee against loss.

You'll also want to analyze the individual investments in your portfolio. Of
course, performance should be a key factor in your analysis, but it's not the
only factor to consider. Make sure the investments in your portfolio line up
with your overall objectives and risk tolerance. Be aware of changes in
portfolio management and pay special attention to any funds that have made
significant shifts in their investment strategy.

We hope this information will help you, in working with your financial advisor,
to stay on track to reach your investment goals. Thank you for your business
and for your continued confidence in Columbia Funds.

Sincerely,

/s/ Christopher L. Wilson

Economic Update - Columbia Income Fund


  Summary

  For the 12-month period ended March 31, 2007
 . Investment-grade bonds rebounded as yields declined, lifting the Lehman
   Brothers U.S. Aggregate Bond Index to a respectable return. High-yield
   bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led
   the US fixed-income markets.


                                               
                    Lehman                                         Merrill Lynch
                     Index                                             Index

                     6.59%                                            11.45%


 . The broad US stock market, as measured by the S&P 500 Index, returned
   11.83%. Stock markets outside the United States were even stronger, as
   measured by the MSCI EAFE Index.



                                               
                   S&P Index                                        MSCI Index

                                      [GRAPHIC]                                         [GRAPHIC]


                    11.83%                                            20.20%


  The Lehman Brothers U.S. Aggregate Bond Index is a market value-weighted
  index that tracks the daily price, coupon, pay-downs, and total return
  performance of fixed-rate, publicly placed, dollar-denominated, and
  non-convertible investment grade debt issues with at least $250 million par
  amount outstanding and with at least one year to final maturity.
  The Merrill Lynch U.S. High Yield, Cash Pay Index tracks the performance of
  non-investment-grade corporate bonds.
  The S&P 500 Index tracks the performance of 500 widely held,
  large-capitalization US stocks.
  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.
  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.


US economic growth advanced at a modest pace during the 12-month period that
began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on
the economy throughout the period, with few signs that relief was imminent.
Energy prices trended downward, but rose again late in the period, and core
inflation moved higher. Yet, many economic indicators remained positive. Job
growth, for example, was relatively strong, as the labor markets added an
average of 164,000 new jobs each month over the period and the unemployment
rate declined to 4.4%. Personal income rose and consumer spending continued to
expand, albeit at a slower pace as the period wore on. Against this backdrop,
economic growth averaged around 2.2% for the 12-month period.

Between April and June 2006, the Federal Reserve Board (the Fed) raised a key
short-term interest rate, the federal funds rate, twice -- to 5.25%. But after
its June meeting, the Fed turned cautious in the face of slower economic growth
and held the federal funds rate steady. Investors reacted favorably to the
prospect of stable or lower interest rates and fueled a rally that moved stock
prices higher and gave a boost to the bond market as well.

Bonds bounced back
Although bond yields moved higher early in the period, most segments of the US
bond market delivered respectable returns, as prices rose and yields declined
in reaction to the Fed's mid-year decision to put further short-term rate
increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether
for the bond market, ended the 12-month period at 4.63% -- somewhat lower than
where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond
Index returned 6.59%. High-yield bonds led the US fixed-income markets,
reflecting investor confidence about the overall resilience of the economy
despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay
Index returned 11.45%.

Despite late set-back, stocks moved solidly higher
Stock prices rose at an above-average pace during the 12-month period covered
by this report. The S&P 500 Index, a broad measure of common stock performance,
rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap
stocks, as measured by their respective Russell indices. Foreign stock markets
were even stronger than the US market. The MSCI EAFE Index, which tracks stock
market performance in industrialized countries outside the United States,
returned 20.20%, despite a volatile stretch late in the period when the US and
many foreign stock markets retreated in response to a sharp decline in the
Chinese market and other market-specific factors.

The "with sales charge" returns include the maximum initial sales charge of
4.75% for Class A shares, the maximum contingent deferred sales charge of 5.00%
in the first year, declining to 1.00% in the sixth year, and eliminated
thereafter for Class B shares and 1.00% for Class C shares for the first year
only. The "without sales charge" returns do not include the effect of sales
charges. If they had, returns would be lower.
Performance results reflect any waivers or reimbursements of fund expenses by
the investment advisor and/or any of its affiliates. Absent these waivers or
reimbursement arrangements, performance results would have been lower.
All results shown assume reinvestment of distributions. Performance for
different share classes will vary based on differences in sales charges and
fees associated with each class. Class Z shares are sold at net asset value
with no Rule 12b-1 fees. Class Z shares have limited eligibility and the
investment minimum requirements may vary. Please see the fund's prospectus for
details.
The table does not reflect the deduction of taxes that a shareholder would pay
on fund distributions or the redemption of fund shares.
The returns of Class A shares include returns of the fund's Class Z shares (the
oldest existing fund share class) for periods prior to the inception of Class A
shares. The returns of Class B and Class C shares include returns of the fund's
Class A shares for periods prior to the inception of Class B and Class C
shares, respectively. The returns of Class B and Class C shares also include
returns of the fund's Class Z shares for periods prior to the inception of
Class A shares. These returns have not been restated to reflect any differences
in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A, Class
B or Class C shares or between Class A shares and Class B or Class C shares. If
differences in expenses had been reflected, the returns shown for Class A,
Class B and Class C shares for periods prior to the inception of Class A, Class
B and Class C shares, respectively, would have been lower. Class A shares were
initially offered on July 31, 2000, Class B and Class C shares were initially
offered on July 15, 2002, and Class Z shares were initially offered on March 5,
1986.

Understanding Your Expenses - Columbia Income 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 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 the 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 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 is
calculated based on the fund's actual operating expenses. 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.

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 ongoing cost of investing in a fund and do
not reflect any transaction costs, such as sales charges, redemption fees or
exchange fees.

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/or any of its affiliates not waived or
reimbursed a portion of expenses, account value 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 fund and do not reflect any

For the 12-month period that ended March 31, 2007, Columbia Income Fund Class A
shares returned 6.04% without sales charge. The fund's return was lower than
the returns of its benchmarks, the Lehman Brothers Intermediate
Government/Credit Bond Index and the Lehman Brothers Intermediate Credit Bond
Index, which returned 6.14% and 6.82%, respectively, for the same period./1/
The fund's return was also lower than the average return of its peer group the
Lipper Corporate Debt Funds BBB Rated Classification, which was 6.88% for the
12-month period./2/ Allocation decisions within the financial sector accounted
for the performance shortfall.

The past 12 months were a fairly stable period for the fixed-income markets.
Three months into the period, the Federal Reserve Open Market Committee (the
Fed) suspended its two-year-long string of short-term interest rate hikes, and
stayed on the sidelines for the remainder of the period. Meanwhile, inflation
remained moderate enough to bring long-term rates down slightly. The net result
was a healthy bond market. While long-term bonds tended to outperform issues
with shorter maturities, solid gains were posted at all points of the maturity
spectrum.

Steady economic growth favored corporate bonds
The national economy managed to stay in a sweet spot characterized by strong
growth and the absence of undue inflationary pressures. The economy's steady
growth created a favorable environment for corporate bonds, consistent with a
general trend in which fixed-income investors were rewarded for assuming credit
risk. In particular, high-yield bonds were the top performing bond market
sector during the period. Our decision to overweight the high-yield sector
enabled the fund to maintain its competitiveness with other intermediate bond
funds.

However, this reward for risk-taking did not extend to the mortgage market.
Toward the end of the period, a surge in foreclosures experienced by subprime
lenders resulted in significant losses for low-quality mortgage pools. While
the fund's exposure to subprime securities was limited, many of its mortgage
holdings lost ground as investors worried that problems could spill over to
other areas of the market.

The fund's sector decisions experienced mixed results during the period.
Positions in the financial sector helped performance for the first six months,
then hampered performance in the second half, above and beyond subprime
concerns. A decision to underweight the insurance sector also hampered
performance as major carriers delivered above-average performance after a mild
hurricane year. We plan to add to the fund's insurance holdings because of the
balance sheet improvements created by the limited payouts of the past year and
limited subprime exposure. In addition, we believe insurers appear to be less
likely than other financial companies to be candidates for a private equity
transaction.

/1/The Lehman Brothers Intermediate Government/Credit Bond Index tracks the
   performance of intermediate term US government and corporate bonds. The
   Lehman Brothers Intermediate Credit Bond Index is the intermediate component
   of the U.S. Credit Index. The U.S. Credit Index includes publicly issued US
   corporate and foreign debentures and secured notes that meet specified
   maturity, liquidity, and quality requirements. Indices are not investments,
   do not incur fees, expenses or taxes and are not professionally managed. It
   is not possible to invest directly in an index.
/2/Lipper Inc., a widely respected data provider in the industry, calculates an
   average total return (assuming reinvestment of distributions) for mutual
   funds with investment objectives similar to those of the fund. Lipper makes
   no adjustment for the effect of sales loads.

Portfolio Managers' Report (continued) - Columbia Income Fund



Looking ahead
We plan to take a more neutral view of the high-yield market now that low
quality issues offer historically low yield advantages versus investment-grade
credits. The fund is currently overweight in AAA and BBB-rated bonds, whose
prospects we believe remain attractive given our constructive outlook for the
economy as a whole. While the bond market still faces an elevated risk of
shareholder-friendly leveraged transactions, we believe such risks are to a
large degree priced into today's yield levels.

  Management style is determined by Columbia Management and is based on the
  investment strategy and process as outlined in the fund's prospectus.

Summary
.. For the 12-month period that ended March 31, 2007, the fund's Class A shares
  returned 6.04 % without sales charge.

.. The fund's return was lower than the return of its benchmark and the average
  return of its peer group.

.. The fund had more exposure than the indices to high-yield bonds, the
  best-performing sector of the fixed-income market, which benefited
  performance. However, the composition of holdings in the financial sector
  hurt relative performance in the second half of the period.

Portfolio Management
Kevin L. Cronk has co-managed the Columbia Income Fund since March 2003 and has

Portfolio holdings and characteristics are subject to change and may not be
representative of current holdings and characteristics. The outlook for this
fund may differ from that presented for other Columbia Funds. Performance for
different classes of shares will vary based on differences in sales charges and
fees associated with each class. For standardized performance, please refer to
the Performance Information page.

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.

Investing in high-yield securities (commonly known as "junk" bonds) offers the
potential for high current income and attractive total return but involves
certain risks. Changes in economic conditions or other circumstances may
adversely affect a junk bond issuer's ability to make principal and interest
payments. Rising interest rates tend to lower the value of all bonds.
High-yield bonds issued by foreign entities have greater potential risks,
including less regulation, currency fluctuations, economic instability and
political developments.

                                    -------------------------------------
      Investment Portfolio          The investment portfolio details all
                                    of the fund's holdings and their
                                    values as of the last day of the
                                    reporting period. Portfolio holdings
                                    are organized by type of asset,
                                    industry, country or geographic
                                    region (if applicable) to demonstrate
                                    areas of concentration and
                                    diversification.

      Statement of Assets and       This statement details the fund's
      Liabilities                   assets, liabilities, net assets and
                                    share price for each share class as
                                    of the last day of the reporting
                                    period. Net assets are calculated by
                                    subtracting all the fund's
                                    liabilities (including any unpaid
                                    expenses) from the total of the
                                    fund's investment and non-investment
                                    assets. The share price for each
                                    class is calculated by dividing net
                                    assets for that class by the number
                                    of shares outstanding in that class
                                    as of the last day of the reporting
                                    period.
                                    -------------------------------------
      Statement of Operations       This statement details income earned
                                    by the fund and the expenses accrued
                                    by the fund during the reporting
                                    period. This statement also shows any
                                    net gain or loss the fund realized on
                                    the sales of its holdings during the
                                    period, as well as any unrealized
                                    gains or losses recognized over the
                                    period. The total of these results
                                    represents the fund's net increase or
                                    decrease in net assets from
                                    operations.

Notes to Financial Statements - Columbia Income Fund

March 31, 2007

Note 1. Organization
Columbia Income Fund (the "Fund"), a series of Columbia Funds Series Trust I
(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 its total return by investing for a high level of current income
and, to a lesser extent, capital appreciation.

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 subject to a maximum front-end sales charge of 4.75% based
on the amount of initial investment. Class A shares purchased without an
initial sales charge in accounts aggregating up to $50 million at the time of
purchase are subject to a 1.00% contingent deferred sales charge ("CDSC") if
the shares are sold within twelve months of the time of the purchase. Class B
shares are subject to a maximum CDSC of 5.00% based upon the holding period
after purchase. Class B shares will convert to Class A shares eight years after
purchase. 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
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.

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

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

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 4:00 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

38




Columbia Income Fund

March 31, 2007

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 that 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 "fair value", such value is likely to be different from
the last quoted market price for the security.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is evaluating the impact the application of
SFAS 157 will have on the Fund's financial statement disclosures.

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. 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. Although 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. The
counterparty risk exposure is, therefore, closely monitored and contracts are
only executed with high credit quality financial institutions.

Repurchase Agreements
The Fund may engage in repurchase agreement transactions with institutions that
Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy.
The Fund, through its custodian, receives delivery of underlying securities
collateralizing a repurchase agreement. Columbia is responsible for determining
that 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.

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 holds until
settlement date, in a segregated account, cash or liquid securities in an
amount equal to the delayed delivery commitment.

Mortgage Dollar Roll Transactions
The Fund may enter into mortgage "dollar rolls" in which the Fund sells
securities for delivery in the current month and

                                                                             39




Columbia Income Fund

March 31, 2007

simultaneously contracts with the same counterparty to repurchase similar (same
type, coupon and maturity) but not identical securities on a specified future
date not exceeding 120 days. During the roll period, the Fund loses the right
to receive principal and interest paid on the securities sold. However, the
Fund would benefit to the extent of any difference between the price received
for the securities sold and the lower forward price for the future purchase
(often referred to as the "drop") or fee income plus the interest earned on the
cash proceeds of the securities sold until the settlement date of the forward
purchase. Unless such benefits exceed the income, capital appreciation and gain
or loss due to mortgage prepayments that would have been realized on the
securities sold as part of the mortgage dollar roll, the use of this technique
will diminish the investment performance of the Fund compared with what such
performance would have been without the use of mortgage dollar rolls. All cash
proceeds will be invested in instruments that are permissible investments for
the Fund. The Fund will hold and maintain in a segregated account until the
settlement date, cash or liquid securities in an amount equal to the forward
purchase price.

The Fund's policy is to record the components of mortgage dollar rolls using
"to be announced" mortgage-backed securities ("TBA Dollar Rolls"). For
financial reporting and tax purposes, the Fund treats mortgage dollar rolls as
two separate transactions, one involving the purchase of a security and a
separate transaction involving a sale. The Fund does not currently enter into
mortgage dollar rolls that are accounted for as financing.

Mortgage dollar rolls involve certain risks. If the broker-dealer to whom the
Fund sells the security becomes insolvent, the Fund's right to purchase or
repurchase the mortgage-related securities may be restricted and the instrument
which the Fund is required to repurchase may be worth less than an instrument
which the Fund originally held. Successful use of mortgage dollar rolls may
depend upon the investment advisor's ability to predict correctly interest
rates and mortgage prepayments. For these reasons, there is no assurance that
mortgage dollar rolls can be successfully employed.

Futures Contracts
The Fund may invest in futures contracts to gain or reduce exposure to
particular securities or segments of the bond markets. Derivatives are
financial instruments whose values depend on, or derived from, the value of the
underlying security, index, or currency. The Fund may use derivatives for both
hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to
changes in interest rates, or to offset a potential loss in one position by
establishing an opposite position. The fund typically uses derivatives in an
effort to achieve more efficiently economic exposure similar to those it could
have achieved through the purchase and sale of fixed income securities. 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 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 recognizes a
realized gain or loss when the contract is closed or expires.

Income Recognition
Interest income is recorded on the accrual basis. Premium and discount are
amortized and accreted, respectively, on all debt securities. Fee income
attributable to a mortgage dollar roll transaction is accrued 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 in the Statement of Operations.

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

Indemnification
In the normal course of business, the Fund enters into contracts that contain a
variety of representations and warranties and which provide general
indemnities. The Fund's maximum exposure under these arrangements is unknown,
as this would involve future claims against the Fund. Also, under the Fund's
organizational documents and by contract, the trustees and officers of the
Trust are indemnified against certain liabilities that may arise out of their
duties to the Trust. However, based on experience, the Fund expects the risk of
loss due to these representations, warranties and indemnities to be minimal.

Note 3. Federal Tax Information
The timing and character of income and capital gain distributions are
determined in accordance with income tax regulations, which may differ from
GAAP. Reclassifications are made to the Fund's capital accounts for permanent
tax differences to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

For the year ended March 31, 2007, permanent book and tax basis differences
resulting primarily from differing treatments for in-kind redemptions, discount
accretion/premium amortization on debt securities and paydown gain/loss
reclasses were identified and reclassified among the components of the Fund's
net assets as follows:



                  Overdistributed Accumulated
                  Net Investment  Net Realized
                  Income          Loss         Paid-In Capital
                                         
                  $1,550,220      $(1,430,526) $(119,694)


Net investment income and net realized gains (losses), as disclosed on the
Statement of Operations, and net assets were not affected by this
reclassification.

The tax character of distributions paid during the years ended March 31, 2007
and March 31, 2006 was as follows:



                                      March 31, 2007 March 31, 2006
             Distributions paid from:
                                               
                 Ordinary Income*      $30,313,269    $30,696,439

*For tax purposes short-term capital gains distributions, if any, are
 considered ordinary income distributions.

As of March 31, 2007, the components of distributable earnings on a tax basis
were as follows:



                   Undistributed Undistributed Net
                   Ordinary      Long-Term     Unrealized
                   Income        Capital Gains Appreciation*
                                         
                   $1,163,993    $--           $2,011,940

*The differences between book-basis and tax-basis net unrealized appreciation
 are primarily due to differing treatments of capital loss carryforwards,
 futures contracts, forward currency contracts, distribution reclassifications
 and discount accretion/premium amortization on debt securities and deferral of
 losses from wash sales.

Unrealized appreciation and depreciation at March 31, 2007, based on cost of
investments for federal income tax purposes were:



                                             
                    Unrealized appreciation     $ 8,750,055
                    Unrealized depreciation      (6,738,115)
                    Net unrealized appreciation $ 2,011,940


                                                                             41




Columbia Income Fund

March 31, 2007


The following capital loss carryforwards, determined as of March 31, 2007, may
be available to reduce taxable income arising from future net realized gains on
investments, if any, to the extent permitted by the Internal Revenue Code:



                  Year of Expiration Capital Loss Carryforward
                                  
                  2008                             $ 7,932,135
                  2009                               8,620,038
                  2010                               1,393,345
                  2011                               2,985,140
                  2014                               3,731,648
                  2015                               6,709,359
                  Total                            $31,371,665


Of the capital loss carryforwards attributable to the Fund, $10,086,973
($4,838,296 will expire March 31, 2008, $3,855,332 will expire March 31, 2009
and $1,393,345 will expire March 31, 2010) was obtained in a merger with
Liberty Income Fund.

Under current tax rules, certain currency and capital losses realized after
October 31 may be deferred and treated as occurring on the first day of the
following fiscal year. As of March 31, 2007, capital losses of $292,784
attributed to security transactions were deferred to April 1, 2007.

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109 (the "Interpretation"). This
Interpretation is effective on the last business day of the semiannual
reporting period for fiscal years beginning after December 15, 2006 and is to
be applied to open tax positions upon initial adoption. This Interpretation
prescribes a minimum recognition threshold and measurement method for the
financial statement recognition of tax positions taken or expected to be taken
in a tax return and also requires certain expanded disclosures. Management is
evaluating the application of this Interpretation to the Fund and has not at
this time quantified the impact, if any, resulting from the adoption of this
Interpretation on the Fund's financial statements.

Note 4. Fees and Compensation Paid to Affiliates

Investment Advisory Fee
Columbia, an indirect, wholly-owned subsidiary of Bank of America Corporation
("BOA"), is the investment advisor to the Fund. Columbia receives a monthly
investment advisory fee based on the Fund's average daily net assets at the
following annual rates:



                   Average Daily Net Assets   Annual Fee Rate
                                           
                   First $500 million         0.420%
                   $500 million to $1 billion 0.375%
                   $1 billion to $1.5 billion 0.370%

                   Over $6 billion            0.320%


For the year ended March 31, 2007, the Fund's effective investment advisory fee
rate was 0.42% of the Fund's average daily net assets.

Administration Fee
Columbia provides administrative and other services to the Fund for a monthly
administration fee based on the Fund's average daily net assets at the
following annual rates:



                   Average Daily Net Assets   Annual Fee Rate
                                           
                   First $100 million         0.150%
                   $100 million to $1 billion 0.125%
                   Over $1 billion            0.100%


For the year ended March 31, 2007, the Fund's effective administration fee rate
was 0.13% of the Fund's average daily net assets.

Pricing and Bookkeeping Fees
Effective December 15, 2006, the Fund entered into a Financial Reporting
Services Agreement with State Street Bank & Trust Company ("State Street") and
Columbia (the "Financial Reporting Services Agreement") pursuant to which State
Street provides financial reporting services to the Fund. Also effective
December 15, 2006, the Fund entered into an Accounting Services Agreement with
State Street and

42




Columbia Income Fund

March 31, 2007

Columbia (collectively with the Financial Reporting Services Agreement, the
"State Street Agreements") pursuant to which State Street provides accounting
services to the Fund. Under the State Street Agreements, the Fund pays State
Street an annual fee of $38,000 paid monthly plus an additional monthly fee
based on an annualized percentage rate of average daily net assets of the Fund
for the month. Under the State Street Agreements, the combined fee payable to
State Street by the Fund will not exceed $140,000 annually. The Fund also
reimburses State Street for certain out-of-pocket expenses.

Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping
Oversight and Services Agreement (the "Services Agreement") with Columbia.
Under the Services Agreement, Columbia provides services related to Fund
expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides
oversight of the accounting and financial reporting services provided by State
Street. Under the Services Agreement, the Fund reimburses Columbia for
out-of-pocket expenses and direct internal costs relating to accounting
oversight and for services related to Fund expenses and the requirements of the
Sarbanes-Oxley Act of 2002.

Prior to December 15, 2006, Columbia was responsible for providing pricing and
bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under its pricing and bookkeeping agreement with the Fund, Columbia was
entitled to receive an annual fee at the same fee structure described above
under the State Street Agreements. Under separate agreements between Columbia
and State Street, Columbia delegated certain functions to State Street. As a
result of the delegation, the total fees payable under the pricing and
bookkeeping agreement (other than certain reimbursements paid to Columbia and
discussed below) were paid to State Street. The Fund also reimbursed Columbia
and State Street for out-of-pocket expenses and charges, including fees payable
to third parties for pricing the Fund's portfolio securities and direct
internal costs incurred by Columbia in connection with providing fund
accounting oversight and monitoring and certain other services.

For the year ended March 31, 2007, the Fund's effective pricing and bookkeeping
fee rate, inclusive of out-of-pocket expenses, was 0.033% of the Fund's average
daily net assets.

Transfer Agent Fee
Columbia Management Services, Inc. (the "Transfer Agent"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, provides shareholder
services to the Fund and has contracted with Boston Financial Data Services
("BFDS") to serve as sub-transfer agent. The Transfer Agent is entitled to
receive a fee for its services, paid monthly, at the annual rate of $17.00 per
open account plus reimbursement of certain sub-transfer agent fees (exclusive
of BFDS fees) calculated based on assets held in omnibus accounts and intended
to recover the cost of payments to other parties (including affiliates of BOA)
for services to those accounts. The Transfer Agent pays the fees of BFDS for
services as sub-transfer agent and is not entitled to reimbursements for such
fees from the Fund. The Transfer Agent may also retain, as additional
compensation for its services, fees for wire, telephone and redemption orders,
IRA trustee agent fees and account transcript fees due the Transfer Agent from
shareholders of the Fund and credits (net of bank charges) earned with respect
to balances in accounts the Transfer Agent maintains in connection with its
services to the Fund. The Transfer Agent also receives reimbursement for
certain out-of-pocket expenses.

For the year ended March 31, 2007, the Fund's effective transfer agent fee
rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was
0.07% of the Fund's average daily net assets.

Underwriting Discounts, Service and Distribution Fees
Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal
underwriter of the Fund. For the year ended March 31, 2007, the Distributor has
retained net underwriting discounts of $17,869 on sales of the Fund's Class A
shares and net CDSC fees of $146, $42,193 and $4,239 on Class A, Class B and
Class C share redemptions, respectively.

The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of
a monthly service fee to the Distributor at the annual rate of 0.25% of the
average daily net assets attributable to Class A, Class B and Class C shares of
the Fund. The Plan also requires the payment of a monthly distribution fee to
the Distributor at the annual rate of 0.75%

                                                                             43




Columbia Income Fund

March 31, 2007

of the average daily net assets 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 0.60% annually of Class C
average daily net assets. These waivers may be modified or terminated by the
Distributor at any time.

The CDSC and the distribution 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 in 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
All officers of the Fund are employees of Columbia or its affiliates and, with
the exception of the Fund's Chief Compliance Officer, receive no compensation
from the Fund. The Board of Trustees has appointed a Chief Compliance Officer
to the Fund in accordance with federal securities regulations. The Fund, along
with other affiliated funds, pays its pro-rata share of the expenses associated
with the Chief Compliance Officer. The Fund's expenses for 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 the requirements of
the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund
paid $2,875 to Columbia for such services. This amount is included in "Other
expenses" in the Statement of Operations.

Note 5. Portfolio Information
For the year ended March 31, 2007, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $954,353,413 and
$770,695,484, respectively, of which $271,381,164 and $306,200,420,
respectively, were U.S. Government securities.

Note 6. Line of Credit
The Trust and other affiliated funds participate in a $350,000,000 committed
unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured
line of credit, both provided by State Street. Borrowings are available for
temporary or emergency purposes.

Interest on the committed line of credit is charged to each participating fund
based on the fund's borrowings at a rate per annum equal to the Federal Funds
Rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued
and apportioned among the participating funds based on their pro-rata portion
of the unutilized committed line of credit. Interest on the uncommitted line of
credit is charged to each participating fund based on the fund's borrowings at
a variable rate per annum equal to the Federal Funds Rate plus a spread, as
determined and quoted by State Street at the time of the request for a loan. A
one-time structuring fee of $30,000 is also accrued and apportioned to each
fund participating in the uncommitted line of credit based on the average net
assets of the participating funds. In addition, if the uncommitted line of
credit is extended for an additional period, an annual administration fee of
$15,000 will be charged and apportioned among the participating fund. The
commitment fee and structuring fee are included in "Other expenses" in the
Statement of Operations.

For the year ended March 31, 2007, the Fund did not borrow under this
arrangement.

Note 7. Shares of Beneficial Interest
As of March 31, 2007, the Fund had one shareholder that held 41.8% of the
shares outstanding. These shares were beneficially owned by participant
accounts over which BOA and/or its affiliates had either sole or joint
investment discretion. Subscription and redemption activity of these accounts
may have a significant effect on the operations of the Fund.

As of March 31, 2007, the Fund had one shareholder that held 8.6% of the shares
outstanding. These shares were beneficially owned by participant accounts over
which BOA

44




Columbia Income Fund

March 31, 2007

and/or its affiliates did not have investment discretion. Subscription and
redemption activity of these accounts may have a significant effect on the
operations of the Fund.

Note 8. Securities lending
The Fund commenced a securities lending program in August 2006 and may lend its
securities to certain approved brokers, dealers and other financial
institutions. Each loan is collateralized by cash, in an amount at least equal
to the market value of the securities loaned plus accrued income from the
investment of collateral. The market value of the loaned securities is
determined at the close of business of the Fund and any additional required
collateral is delivered to the Fund on the next business day. The collateral
received is invested and the income generated by the investment of the
collateral, net of any fees remitted to State Street as the lending agent and
borrower rebates, is paid to the Fund. Generally, in the event of borrower
default, the Fund has the right to use the collateral to offset any losses
incurred. In the event the Fund is delayed or prevented from exercising its
right to dispose of the collateral, there may be a potential loss to the Fund.
The Fund bears the risk of loss with respect to the investment of collateral.

Note 9. Other
During the year ended March 31, 2007, the Fund had a realized investment loss
in the amount of $3,209 due to a trading error. Columbia voluntarily reimbursed
the Fund for the loss.

Note 10. 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 may be less liquid to the extent that there is no
established secondary market.

Sector Focus
Companies that are in different but closely related industries are sometimes
described as being in the same sector. Although the Fund does not intend to
focus on any particular sector, at times the Fund may have a large portion of
its assets invested in a particular sector. During such times, the Fund will
have greater exposure to the economic and market events affecting such sector
than if it were more broadly invested across multiple sectors.

Legal Proceedings
On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged
into Banc of America Capital Management, LLC (now named Columbia Management
Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has
been renamed Columbia Management Distributors, Inc.) (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") on matters
relating to mutual fund trading. The SEC Order and the NYAG Settlement are
referred to collectively as the "Settlements".

Under the terms of the SEC Order, the Columbia Group 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 to reduce management fees for certain
Columbia Funds (including the former Nations Funds) and other mutual funds
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 that was

                                                                             45

developed by an independent distribution consultant and approved by the SEC on
April 6, 2007.

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 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.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation
transferred these cases and cases against other mutual fund companies based on
similar allegations to the United States District Court in Maryland for
consolidated or coordinated pretrial proceedings (the ''MDL''). Subsequently,
additional related cases were transferred to the MDL. On September 29, 2004,
the plaintiffs in the MDL filed amended and consolidated complaints. One of
these amended complaints is a putative class action that includes claims under
the federal securities laws and state common law, and that names Columbia, the
Distributor, the Trustees of the Columbia Funds, Bank of America Corporation
and others as defendants. Another of the amended complaints is a derivative
action purportedly on behalf of the Columbia Funds that asserts claims under
federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss
the claims in the pending cases. On March 1, 2006, for reasons stated in the
court's memoranda dated November 3, 2005, the U.S. District Court for the
District of Maryland granted in part and denied in part the defendants' motions
to dismiss. The court dismissed all of the class action claims pending against
the Columbia Funds Trusts. As to Columbia and the Distributor, the claims under
the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the
Investment Company Act of 1940 ("ICA") and the state law claims were dismissed.
The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of
1934 and claims under Section 36(b) of the ICA were not dismissed.

On March 21, 2005, a purported class action was filed in Massachusetts state
court alleging that certain conduct, including market timing, entitled Class B
shareholders in certain Columbia funds to an exemption from contingent deferred
sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was
removed to federal court in Massachusetts and the federal Judicial Panel
transferred the CDSC Lawsuit to the MDL.

On April 4, 2006, the plaintiffs and the Columbia defendants named in the MDL,
including the Columbia Funds, entered into a term sheet containing the
principal terms of a stipulation of settlement that would settle all
Columbia-related claims in the MDL described above, including the CDSC Lawsuit.
On April 6, 2006, the U.S. District Court for the District of Maryland stayed
all actions with respect to these Columbia-related claims. The settlement is
subject to court approval.

In 2004, the Columbia Funds' adviser and distributor and certain affiliated
entities and individuals 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.
Certain Columbia Funds were named as nominal defendants. 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 purposes. 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. On November 30, 2005, the judge dismissed all claims by
plaintiffs and entered final judgment in favor of the defendants. The
plaintiffs appealed to the United States Court of Appeals for the First Circuit
on December 30, 2005. A stipulation and settlement agreement dated January 19,
2007 was filed in the First Circuit on February 14, 2007, with a joint
stipulation of dismissal and motion for remand to obtain district court
approval of the settlement. That joint motion was granted and the appeal was
dismissed. On March 6, 2007, the case was remanded to the District Court. On
May 11, 2007, the District Court entered a preliminary approval order which
granted preliminary approval of the settlement. A final settlement hearing, at
which the District Court will determine whether the proposed settlement should
be finally approved and the action dismissed on the merits with prejudice, is
scheduled for September 18, 2007. The terms of the settlement, if finally
approved, will require payments by the funds' adviser and/or its affiliates,
including payment of plaintiffs' attorneys' fees and notice to class members.
In the event that the settlement is not finally approved, the plaintiffs may
elect to go forward with their appeal and no opinion is expressed regarding the
likely outcome or financial impact of such an appeal on any fund.

Report of Independent Registered Public Accounting Firm


To the Trustees of Columbia Funds Series Trust I and the Shareholders of
Columbia Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Columbia Income Fund (the "Fund")
(a series of Columbia Funds Series Trust I) at March 31, 2007, and the results
of its operations, the changes in its net assets and the financial highlights
for the periods indicated in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at March 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion. The
financial highlights of the Fund for periods prior to July 1, 2003 were audited
by another independent registered public accounting firm whose report dated
August 19, 2003 expressed an unqualified opinion on those statements.

                                                                             51




Board Consideration and Approval of Investment Advisory Agreements

The Advisory Fees and Expenses Committee of the Board of Trustees meets one or
more times annually to review the advisory agreements (collectively, the
"Agreements") of the funds for which the Trustees serve as trustees (each a
"fund") and determine whether to recommend that the full Board approve the
continuation of the Agreements for an additional one-year period. After the
Committee has made its recommendation, the full Board, including the
Independent Trustees, determines whether to approve the continuation of the
Agreements. In addition, the Board, including the Independent Trustees,
considers matters bearing on the Agreements at most of its other meetings
throughout the year and meets regularly with the heads of each investment area
within Columbia. Through the Board's Investment Oversight Committees, Trustees
also meet with selected fund portfolio managers at various times throughout the
year.

The Trustees receive and review all materials that they, their legal counsel or
Columbia, the funds' investment adviser, believe to be reasonably necessary for
the Trustees to evaluate the Agreements and determine whether to approve the
continuation of the Agreements. Those materials generally include, among other
items, (i) information on the investment performance of each fund relative to
the performance of peer groups of mutual funds and the fund's performance
benchmarks, (ii) information on each fund's advisory fees and other expenses,
including information comparing the fund's expenses to those of peer groups of
mutual funds and information about any applicable expense caps and fee
"breakpoints," (iii) information about the profitability of the Agreements to
Columbia, including potential "fall-out" or ancillary benefits that Columbia
and its affiliates may receive as a result of their relationships with the
funds and (iv) information obtained through Columbia's response to a
questionnaire prepared at the request of the Trustees by counsel to the funds
and independent legal counsel to the Independent Trustees. The Trustees also
consider other information such as (v) Columbia's financial results and
financial condition, (vi) each fund's investment objective and strategies and
the size, education and experience of Columbia's investment staffs and their
use of technology, external research and trading cost measurement tools, (vii)
the allocation of the funds' brokerage, if any, and the use of "soft"
commission dollars to pay for research products and services, (viii) Columbia's
resources devoted to, and its record of compliance with, the funds' investment
policies and restrictions, policies on personal securities transactions and
other compliance policies, (ix) Columbia's response to various legal and
regulatory proceedings since 2003 and (x) the economic outlook generally and
for the mutual fund industry in particular. In addition, the Advisory Fees and
Expenses Committee confers with the funds' independent fee consultant and
reviews materials relating to the funds' relationships with Columbia provided
by the independent fee consultant. Throughout the process, the Trustees have
the opportunity to ask questions of and request additional materials from
Columbia and to consult with independent legal counsel to the Independent
Trustees and the independent fee consultant.

The Board of Trustees most recently approved the continuation of the Agreements
at its October, 2006 meeting, following meetings of the Advisory Fees and
Expenses Committee held in August, September and October, 2006. In considering
whether to approve the continuation of the Agreements, the Trustees, including
the Independent Trustees, did not identify any single factor as determinative,
and each weighed various factors as he or she deemed appropriate. The Trustees
considered the following matters in connection with their approval of the
continuation of the Agreements:

The nature, extent and quality of the services provided to the funds under the
Agreements. The Trustees considered the nature, extent and quality of the
services provided by Columbia and its affiliates to the funds and the resources
dedicated to the funds by Columbia and its affiliates. Among other things, the
Trustees considered (i) Columbia's ability (including its personnel and other
resources, compensation programs for personnel involved in fund management,
reputation and other attributes) to attract and retain highly qualified
research, advisory and supervisory investment professionals; (ii) the portfolio
management services provided by those investment professionals; and (iii) the
trade execution services provided on behalf of the funds. For each fund, the
Trustees also considered the benefits to shareholders of investing in a mutual
fund that is part of a family of funds offering exposure to a variety of asset
classes and investment disciplines and providing a variety of fund and
shareholder services. After reviewing those and related factors, the Trustees
concluded, within the context of their

52






overall conclusions regarding each of the Agreements, that the nature, extent
and quality of services provided supported the continuation of the Agreements.

Investment performance of the funds and Columbia. The Trustees reviewed
information about the performance of each fund over various time periods,
including information prepared by an independent third party that compared the
performance of each fund to the performance of peer groups of mutual funds and
performance benchmarks. The Trustees also reviewed a description of the third
party's methodology for identifying each fund's peer group for purposes of
performance and expense comparisons. The Trustees also considered additional
information that the Advisory Fees and Expenses Committee requested from
Columbia relating to funds that presented relatively weaker performance and/or
relatively higher expenses.

In the case of each fund whose performance lagged that of a relevant peer group
for certain (although not necessarily all) periods, the Trustees concluded that
other factors relevant to performance were sufficient, in light of other
considerations, to warrant continuation of the fund's Agreements. Those factors
varied from fund to fund, but included one or more of the following: (i) that
the fund's performance, although lagging in certain recent periods, was
stronger over the longer term; (ii) that the underperformance was attributable,
to a significant extent, to investment decisions that were reasonable and
consistent with the fund's investment strategy and policies and that the fund
was performing as expected, given these investment decisions, market conditions
and the fund's investment strategy; (iii) that the fund's performance was
competitive when compared to other relevant performance benchmarks or peer
groups; (iv) that Columbia had taken or was taking steps designed to help
improve the fund's investment performance, including, but not limited to,
replacing portfolio managers or modifying investment strategies; and (v) that
the fund was proposed to be reorganized into another fund, and that such
reorganization would result in a reduction in fund expenses.

The Trustees also considered Columbia's performance and reputation generally,
the funds' performance as a fund family generally, and Columbia's historical
responsiveness to Trustee concerns about performance and Columbia's willingness
to take steps intended to improve performance.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
performance of each fund and Columbia was sufficient, in light of other
considerations, to warrant the continuation of the Agreement(s) pertaining to
that fund.

The costs of the services provided and profits realized by Columbia and its
affiliates from their relationships with the funds. The Trustees considered the
fees charged to the funds for advisory services as well as the total expense
levels of the funds. That information included comparisons (provided by
management and by an independent third party) of each fund's advisory fees and
total expense levels to those of the fund's peer groups and information about
the advisory fees charged by Columbia to comparable institutional accounts. In
considering the fees charged to those accounts, the Trustees took into account,
among other things, management's representations about the differences between
managing mutual funds as compared to other types of accounts, including
differences in the services provided, differences in the risk profile of such
business for Columbia, and the additional resources required to manage mutual
funds effectively. In evaluating each fund's advisory fees, the Trustees also
took into account the demands, complexity and quality of the investment
management of the fund. The Trustees considered existing advisory fee
breakpoints, and Columbia's use of advisory fee waivers and expense caps, which
benefited a number of the funds. The Trustees also noted management's stated
justification for the fees charged to the funds, which included information
about the investment performance of the funds and the services provided to the
funds. The Trustees also considered the compensation directly or indirectly
received by Columbia and its affiliates from their relationships with the
funds. The Trustees reviewed information provided by management as to the
profitability to Columbia and its affiliates of their relationships with each
fund, and information about the allocation of expenses used to calculate
profitability. When reviewing profitability, the Trustees also considered court
cases in which adviser profitability was an issue in whole or in part, the
performance of the relevant funds, the expense level of each fund, and whether
Columbia had implemented breakpoints and/or expense caps with respect to the
fund.

                                                                             53







After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
advisory fees charged to each fund, and the related profitability to Columbia
and its affiliates of their relationships with the fund, supported the
continuation of the Agreement(s) pertaining to that fund.

Economies of Scale. The Trustees considered the existence of any economies of
scale in the provision by Columbia of services to each fund, to groups of
related funds, and to Columbia's investment advisory clients as a whole and
whether those economies were shared with the funds through breakpoints in the
investment advisory fees or other means, such as expense waivers/reductions and
additional investments by Columbia in investment, trading and compliance
resources. The Trustees noted that many of the funds benefited from
breakpoints, expense caps, or both. In considering those issues, the Trustees
also took note of the costs of the services provided (both on an absolute and a
relative basis) and the profitability to Columbia and its affiliates of their
relationships with the funds, as discussed above.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
extent to which economies of scale were shared with the funds supported the
continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but
were not limited to the following:

.. the extent to which each fund had operated in accordance with its investment
  objective and investment restrictions, the nature and scope of the compliance
  programs of the funds and Columbia and the compliance-related resources that
  Columbia and its affiliates were providing to the funds;

.. the nature, quality, cost and extent of administrative and shareholder
  services performed by Columbia and its affiliates, both under the Agreements
  and under separate agreements for the provision of transfer agency and
  administrative services;

.. so-called "fall-out benefits" to Columbia and its affiliates, such as the
  engagement of its affiliates to provide distribution, brokerage and transfer
  agency services to the funds, and the benefits of research made available to
  Columbia by reason of brokerage commissions generated by the funds'
  securities transactions, as well as possible conflicts of interest associated
  with those fall-out and other benefits, and the reporting, disclosure and
  other processes in place to disclose and monitor those possible conflicts of
  interest; and

.. the draft report provided by the funds' independent fee consultant, which
  included information about and analysis of the funds' fees, expenses and
  performance.

Based on their evaluation of all factors that they deemed to be material,
including those factors described above, and assisted by the advice of
independent counsel and the independent fee consultant, the Trustees, including
the Independent Trustees, approved the continuance of each of the Agreements
through October 31, 2007.

Summary of Management Fee Evaluation by Independent Fee Consultant

Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between
the Office of Attorney General of New York State and Columbia Management
Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006

  I. Overview

Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors,
Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's
Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates
that CMA may manage or advise a Columbia Fund ("Fund" and together with all
such funds or a group of such funds as the "Funds") only if the Independent
Members of the Fund's Board of Trustees (such Independent Members of the Fund's
Board together with the other members of the Fund's Board, referred to as the
"Trustees") appoint a Senior Officer or retain an Independent Fee Consultant
("IFC") who is to manage the process by which proposed management fees are
negotiated. The AOD further stipulates that the Senior Officer or IFC is to
prepare a written annual evaluation of the fee negotiation process.

On September 14, 2006, the Independent Members of the Funds' Boards retained me
as IFC for the Funds. In this capacity, I have prepared the second annual
written evaluation of the fee negotiation process. I am successor to the first
IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed
to the second annual written evaluation until his resignation as IFC in August
2006 to become Director of the Division of Market Regulation at the U.S.
Securities and Exchange Commission./2/

A. Role of the Independent Fee Consultant
The AOD charges the IFC with "managing the process by which proposed management
fees...to be charged the Columbia Fund are negotiated so that they are
negotiated in a manner which is at arms' length and reasonable and consistent
with this Assurance of Discontinuance." In this role, the IFC does not replace
the Trustees in negotiating management fees with CMA, and the IFC does not
substitute his or her judgment for that of the Trustees about the
reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a
Columbia Fund only if the reasonableness of the proposed management fees is
determined by the Board of Trustees...using...an annual independent written
evaluation prepared by or under the direction of...the Independent Fee
Consultant."

B. Elements Involved in Managing the Fee Negotiation Process
Managing the fee negotiation process has three elements. One involves reviewing
the information provided by CMG to the Trustees for evaluating the proposed
management fees and augmenting that information, as necessary, with additional
information from CMG or other sources and with further analyses of the
information and data. The second element involves reviewing the information and
analysis relative to at least the following six factors set forth in the AOD:

1.The nature and quality of CMA's services, including the Fund's performance;

2.Management fees (including any components thereof) charged by other mutual
  fund companies for like services;

3.Possible economies of scale as the Fund grows larger;

4.Management fees (including any components thereof) charged to institutional
  and other clients of CMA for like services;

5.Costs to CMA and its affiliates of supplying services pursuant to the
  management fee agreements, excluding any intra-corporate profit; and

6.Profit margins of CMA and its affiliates from supplying such services.

1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which
 also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds'
 transfer agent. Before the date of this report, CMA merged into an affiliated
 entity, Banc of America Capital Management, LLC, which was renamed Columbia
 Management Advisors, LLC and which carries on the business of CMA. CFD also
 has been renamed Columbia Management Distributors, Inc.
2I am an independent economic consultant. From August 2005 until August 2006, I
 provided support to Mr. Sirri as an independent consultant. From 1994 to 2004,
 I was Chief Economist at the Investment Company Institute. Earlier, I was
 Section Chief and Assistant Director at the Federal Reserve Board and
 Professor of Economics at Oklahoma State University. I have no material
 relationship with Bank of America or CMG, aside from serving as IFC, and I am
 aware of no material relationship with any of their affiliates. To assist me
 with the report, I engaged NERA Economic Consulting, an independent consulting
 firm that has had extensive experience in the mutual fund industry. I also
 have retained Willkie Farr & Gallagher LLP as counsel to advise me in
 connection with the report.

                                                                             55







The final element involves providing the Trustees with a written evaluation of
the above factors as they relate to the fee negotiation process.

C. Organization of the Annual Evaluation
The 2006 annual evaluation focuses on the six factors and contains a section
for each factor except that CMA's costs and profits from managing the Funds
have been combined into a single section. In each section, the discussion of
the factor considers and analyzes the available data and other information as
they bear upon the fee negotiation process. If appropriate, the discussion in
the section may point out certain aspects of the proposed fees that may warrant
particular attention from the Trustees. The discussion also may suggest other
data, information, and approaches that the Trustees might consider
incorporating into the fee negotiation process in future years.

In addition to a discussion of the six factors, the report reviews the status
of recommendations made in the 2005 IFC evaluation. The 2006 report also
summarizes the findings with regard to the six factors and contains a summary
of recommendations for possible enhancements to the process.

  II. Status of 2005 Recommendations

The 2005 IFC evaluation contains recommendations aimed at enhancing the
evaluation of proposed management fees by Trustees. The section summarizes
those recommendations and includes my assessment of the response to the
recommendations.

1.Recommendation: Trustees should consider requesting more analytical work from
  CMG in the preparation of future 15(c) materials.

  Status: CMG has provided additional analyses to the Trustees on economies of
  scale, a comparative analysis of institutional and retail management fees,
  management fee breakpoints, risk-adjusted performance, fee waivers and
  expense reimbursements, and CMG's costs and profitability.

2.Recommendation: Trustees may wish to consider whether CMG should continue
  expanding the use of Morningstar or other third party data to supplement
  CMG's fee and performance analysis that is now based primarily on Lipper
  reports.

  Status: CMG has used data from Morningstar Inc. to compare with data from
  Lipper Inc. ("Lipper") in performing the Trustees' screening procedures.

3.Recommendation: Trustees should consider whether...the fund-by-fund
  screen...should place comparable emphasis on both basis point and quintile
  information in their evaluation of the funds...Also, the Trustees should
  consider incorporating sequences of one year performance into a fund-by-fund
  screen.

  Status: CMG has not provided Trustees with results of the screening process
  using percentiles. CMG has provided Trustees with information on the changes
  in performance and expenses between 2005 and 2006 and data on one-year
  returns.

4.Recommendation: Given the volatility of fund performance, the Trustees may
  want to consider whether a better method exists than th[e] fee waiver process
  to deal with fund underperformance.

  Status: It is my understanding that the Trustees have determined to address
  fund underperformance not only through fee waivers and expense caps but also
  through discussions with CMG regarding the sources of underperformance. CMG
  has provided Trustees with an analysis of the relationship between
  breakpoints, expense reimbursements, and fee waivers.

5.Recommendation: [Seventy-one] percent of funds [have] yet to reach their
  first management fee breakpoint... Trustees may wish to consider whether the
  results of my ongoing economies-of-scale work affects the underlying economic
  assumptions reflected in the existing breakpoint schedules.

  Status: CMG has prepared a memo for the Trustees discussing its views on the
  nature and sharing of potential economies of scale. The memo discuses CMG's
  view that economies of scale arise at the complex level rather than the fund
  level. The memo also describes steps, including the introduction of
  breakpoints, taken to share economies of scale with shareholders. CMG's
  analysis, however, does not discuss specific sources of economies of scale
  and does not link breakpoints to economies of scale that might be realized as
  the Funds' assets increase.

56







6.Recommendation: Trustees should continue working with management to address
  issues of funds that demonstrate consistent or significant underperformance
  even if the fee levels for the funds are low.

    Status: Trustees monitor performance on an ongoing basis.

  III. Findings

A. General
1.Based upon my examination of the available information and the six factors, I
  conclude that the Trustees have the relevant information necessary to
  evaluate the reasonableness of the proposed management fees for the Funds.
  CMG has provided the Trustees with relevant materials on the six factors
  through the 15(c) contract renewal process and in materials prepared for
  review at Board and Committee meetings.

2.In my view, the process by which the proposed management fees of the Funds
  have been negotiated in 2006 thus far has been, to the extent practicable, at
  arms' length and reasonable and consistent with the AOD.

B. Nature and Quality of Services, Including Performance
3.The performance of the Funds has been relatively strong, especially that of
  fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance
  periods, over 60 percent of the funds have ranked in the top three
  performance quintiles.

4.The performance of the equity Funds overall, though less concentrated in the
  top two quintiles than the fixed income Funds, improved in 2006 relative to
  that in 2005. The fixed-income funds maintained the relatively high
  performance level of 2005 in 2006.

5.The Funds' overall performance adjusted for risk was significantly stronger
  than performance unadjusted for risk. Domestic and international equity
  funds, in particular, moved to higher relative performance rankings after
  adjusting for risk.

6.The procedure used to construct the performance universe in which each Fund's
  performance is ranked relative to comparable funds may bias a Fund's ranking
  upward within that universe. The bias occurs because the performance ranking
  procedure includes all share classes of multi-class funds in the universe and
  because the procedure ranks either no-load or A share classes of the Funds.
  No-load and A share classes generally have lower total expenses than B and C
  shares (owing to B and C shares having higher distribution/service fees) and
  thus, given all else, would outperform many of B and C share classes included
  in the universe. A preliminary analysis that adjusts for the bias results in
  a downward movement in the relative performance for the Funds but does not
  change the general finding that the Funds' performance has been strong
  relative to comparable funds.

C. Management Fees Charged by Other Mutual Fund Companies
7.The Funds' management fees and total expenses are generally low relative to
  those of their peers. At least 56 percent of the Funds are in the first or
  second quintiles with the lowest fees and expenses and nearly three fourths
  or more in the first three quintiles. Equity Funds are more highly
  concentrated in the first three quintiles than fixed-income Funds.

8.The fee and expense rankings as whole are similar to those in 2005 in that
  the majority of funds are ranked in the top quintiles. Nonetheless, a number
  of individual funds experienced a change in ranking between 2005 and 2006.
  This fund-level instability may reflect sensitivity of rankings to the
  composition of the comparison groups, as the membership of the peer groups
  typically changed substantially between the two years.

9.The Liberty Money Market Fund VS appears to have a higher management fee
  structure than that of other Columbia money market funds of comparable asset
  size.

                                                                             57







D. Trustees' Fee and Performance Evaluation Process
10.The Trustees' evaluation process identified 21 funds in 2006 for further
   review based upon their relative performance or expenses. Seventeen of these
   funds had been subject to review in 2004 or 2005.

E. Potential Economies of Scale
11.CMG has prepared a memo for the Trustees containing its views on the sources
   and sharing of potential economies of scale. CMG views economies of scale as
   arising at the complex level and would regard estimates of scale economies
   for individual funds as unreliable. CMG has not, however, identified
   specific sources of economies of scale nor has it provided any estimates of
   the magnitude of any economies of scale. In the memo, CMG also describes
   measures taken by the Trustees and CMG that seek to share any potential
   economies of scale through breakpoints in management fee schedules, expense
   reimbursements, fee waivers, enhanced shareholder services, fund mergers,
   and operational consolidation. These measures, although of significant
   benefit to shareholders, have not been directly linked in the memo to the
   existence, sources, and magnitude of economies of scale.

F. Management Fees Charged to Institutional Clients
12.CMG has provided Trustees with comparisons of mutual fund management fees
   and institutional fees based upon standardized fee schedules and upon actual
   fees. Based upon the information, institutional fees are generally lower
   than the Funds' management fees. This pattern is consistent with the
   economics of the two financial products. Data are not available, however, on
   actual institutional fees at other money managers. Thus, it is not possible
   to determine the extent to which differences between the Funds' management
   fees and institutional fees are consistent with those seen generally in the
   marketplace.

G. Revenues, Expenses, and Profits
13.The financial statements and the methodology underlying their construction
   generally form a sufficient basis for Trustees to evaluate the expenses and
   profitability of the Funds.

  IV. Recommendations

A. Performance
1.Trustees may wish to consider incorporating risk adjusted measures in their
  evaluation of performance. CMG has begun to prepare reports for the Trustees
  with risk adjustments, which could form the basis for formally including the
  measures in the 15(c) materials. To this end, Trustees may wish to have CMG
  prepare documents explaining risk adjustments and describing their advantages
  and disadvantages.

2.Trustees may wish to consider having CMG evaluate the sensitivity of
  performance rankings to the design of the universe. The preliminary analysis
  contained in the evaluation suggests that the method employed by Lipper, the
  source of performance rankings used by the Trustees, may bias performance
  rankings upward.

B. Economies of Scale
3.Trustees may wish to consider having CMG extend its analysis of economies of
  scale by examining the sources of such economies, if any. Identification of
  the sources may enable the Trustees and CMG to gauge their magnitude. It also
  may enable the Trustees and CMG to build upon past work on standardized fee
  schedules so that the schedules themselves are consistent with any economies
  of scale and their sources. Finally, an extension of the analysis may enable
  the Trustees and CMG to develop a framework that coordinates the use of fee
  waivers and expense caps with the standard fee schedules and with any
  economies of scale and their sources.

C. Institutional Fees
4.Trustees may wish to consider encouraging CMG to build further upon its
  expanded analysis of institutional fees by refining the matching of
  institutional accounts with mutual funds, by dating the establishment of each
  institutional account, and by incorporating other accounts, such as
  subadvisory relationships, trusts, offshore funds, and separately managed
  accounts into the analysis.

58







D. Profitability
5.Trustees may wish to consider requesting that CMG expand the reporting of
  revenues and expenses to include more line-item detail for management and
  administration, transfer agency, fund accounting, and distribution.

6.Trustees may wish to consider requesting that CMG provide a statement of its
  operations in the 15(c) materials.

7.Trustees may wish to consider the treatment of the revenue sharing with the
  Private Bank of Bank of America in their review of CMG's profitability.

Respectfully submitted,
John D. Rea

Appendix


Sources of Information Used in the Evaluation

The following list generally describes the sources and types of information
that were used in preparing this report.

1.  Performance, management fees, and expense ratios for the Funds and
    comparable funds from other fund complexes from Lipper and CMG. The sources
    of this information were CMG and Lipper;

2.  CMG's expenses and profitability obtained directly from CMG;

3.  Information on CMG's organizational structure;

4.  Profitability of publicly traded asset managers from Lipper;

5.  Interviews with CMG staff, including members of senior management, legal
    staff, heads of affiliates, portfolio managers, and financial personnel;

6.  Documents prepared by CMG for Section 15(c) contract renewals in 2005 and
    2006;

7.  Academic research papers, industry publications, professional materials on
    mutual fund operations and profitability, and SEC releases and studies of
    mutual fund expenses

8.  Interviews with and documents prepared by Ernst & Young LLP in its review
    of the Private Bank Revenue Sharing Agreement;

9.  Discussions with Trustees and attendance at Board and committee meetings
    during which matters pertaining to the evaluation were considered.

In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data
management and analysis. NERA has extensive experience in the mutual fund
industry that provides unique insights and special knowledge pertaining to my
independent analysis of fees, performance, and profitability. I have also
retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher
LLP as outside counsel to advise me in connection with my evaluation.

Finally, meetings and discussions with CMG staff were informative. My
participation in Board and committee meetings in which Trustees and CMG
management discussed issues relating to management contracts were of great
benefit to the preparation of the evaluation.

        President, Columbia Funds

                     Dear Shareholder:

                     Investing is a long-term process and we are pleased that
                     you have chosen to include the Columbia family of funds in
                     your overall financial plan.

                     Your financial advisor can help you establish an
                     appropriate investment portfolio and periodically review
                     that portfolio. A well balanced portfolio is one of the
                     keys to successful long-term investing. Your portfolio
                     should be diversified across different asset classes and
                     market segments and your chosen asset allocation should be
                     appropriate for your investment goals, risk tolerance and
                     time horizons.

However, creating an investment strategy is not a one-step process. From time
to time, you'll need to re-evaluate your strategy to determine whether your
investment needs have changed. Most experts recommend giving your portfolio a
"check-up" every year.

As you begin your portfolio check-up, consider whether you have experienced any
major life events since the last time you assessed your portfolio. You may need
to tweak your strategy if you have:

.. Gotten married or divorced
.. Added a child to your family
.. Made a significant change in employment
.. Entered or moved significantly closer to retirement
.. Experienced a serious illness or death in the family
.. Taken on or paid off substantial debt

It's important to remember that over time, performance in different market
segments will fluctuate. These shifts can cause your portfolio balance to drift
away from your chosen asset allocation. A periodic portfolio check-up can help
make sure your portfolio stays on track. Remember that asset allocation does
not ensure a profit or guarantee against loss.

You'll also want to analyze the individual investments in your portfolio. Of
course, performance should be a key factor in your analysis, but it's not the
only factor to consider. Make sure the investments in your portfolio line up
with your overall objectives and risk tolerance. Be aware of changes in
portfolio management and pay special attention to any funds that have made
significant shifts in their investment strategy.

We hope this information will help you, in working with your financial advisor,
to stay on track to reach your investment goals. Thank you for your business
and for your continued confidence in Columbia Funds.

Sincerely,

/s/ Christopher L. Wilson

Economic Update - Columbia Intermediate Bond Fund


  Summary
  For the 12-month period that ended March 31, 2007

 . Investment-grade bonds rebounded as yields declined, lifting the Lehman
   Brothers U.S. Aggregate Bond Index to a respectable return. High-yield
   bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led
   the U.S. fixed-income markets.


                                               
                    Lehman                                         Merrill Lynch
                     Index                                             Index

                     6.59%                                            11.45%


 . The broad US stock market, as measured by the S&P 500 Index, returned
   11.83%. Stock markets outside the United States were even stronger, as
   measured by the MSCI EAFE Index.


                                               
                   S&P Index                                        MSCI Index

                                      [GRAPHIC]                                         [GRAPHIC]


                    11.83%                                            20.20%


  The Lehman Brothers U.S. Aggregate Bond Index is a market value-weighted
  index that tracks the daily price, coupon, pay-downs, and total return
  performance of fixed-rate, publicly placed, dollar-denominated, and
  non-convertible investment grade debt issues with at least $250 million par
  amount outstanding and with at least one year to final maturity.
  The Merrill Lynch U.S. High Yield, Cash Pay Index tracks the performance of
  non-investment-grade corporate bonds.
  The S&P 500 Index tracks the performance of 500 widely held,
  large-capitalization US stocks.
  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.
  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.
US economic growth advanced at a modest pace during the 12-month period that
began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on
the economy throughout the period, with few signs that relief was imminent.
Energy prices trended downward, but rose again late in the period, and core
inflation moved higher. Yet, many economic indicators remained positive. Job
growth, for example, was relatively strong, as the labor markets added an
average of 164,000 new jobs each month over the period and the unemployment
rate declined to 4.4%. Personal income rose and consumer spending continued to
expand, albeit at a slower pace as the period wore on. Against this backdrop,
economic growth averaged around 2.2% for the 12-month period.

Between April and June 2006, the Federal Reserve Board (the Fed) raised a key
short-term interest rate, the federal funds rate, twice -- to 5.25%. But after
its June meeting, the Fed turned cautious in the face of slower economic growth
and held the federal funds rate steady. Investors reacted favorably to the
prospect of stable or lower interest rates and fueled a rally that moved stock
prices higher and gave a boost to the bond market as well.

Bonds bounced back

Although bond yields moved higher early in the period, most segments of the US
bond market delivered respectable returns, as prices rose and yields declined
in reaction to the Fed's mid-year decision to put further short-term rate
increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether
for the bond market, ended the 12-month period at 4.63% -- somewhat lower than
where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond
Index returned 6.59%. High-yield bonds led the US fixed-income markets,
reflecting investor confidence about the overall resilience of the economy
despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay
Index returned 11.45%.

Despite late set-back, stocks moved solidly higher

Stock prices rose at an above-average pace during the 12-month period covered
by this report. The S&P 500 Index, a broad measure of common stock performance,
rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap
stocks, as measured by their respective Russell indices. Foreign stock markets
were even stronger than the US market. The MSCI EAFE Index, which tracks stock
market performance in industrialized countries outside the United States and
Canada, returned 20.20%, despite a volatile stretch late in the period when the
US and many foreign stock markets retreated in response to a sharp decline in
the Chinese market and other market-specific factors.

The chart above shows the growth in value of a hypothetical $10,000 investment
in Class A shares of Columbia Intermediate Bond Fund during the stated time
period, and does not reflect the deduction of taxes that a shareholder would
pay on fund distributions or redemption of fund shares. The growth of $10,000
with sales charge for Class A is calculated with an initial sales charge at
4.75%. The Lehman Brothers U.S. Aggregate Bond Index is a market value-weighted
index that tracks the daily price, coupon, pay-downs, and total return
performance of fixed-rate, publicly placed, dollar-denominated, and
non-convertible investment grade debt issues with at least $250 million par
amount outstanding and with at least one year to final maturity. 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.

The "with sales charge" returns include the maximum initial sales charge of
3.25% for Class A shares, the maximum contingent deferred sales charge of 3.00%
in the first year, declining to 1.00% in the fourth year, and eliminated
thereafter for Class B shares and 1.00% for Class C shares for the first year
only. The "without sales charge" returns do not include the effect of sales
charges. If they had, returns would be lower. Prior to August 22, 2005, new
purchases of Class A shares had a maximum initial sales charge of 4.75%. The 5
&10 year average annual returns with sales charge as of 3/31/07 include the
previous sales charge of 4.75%. The 1 year return with sales charge as of
3/31/07 includes the new sales charge of 3.25%.
Performance results reflect any waivers or reimbursements of fund expenses by
the investment advisor and/or any of its affiliates. Absent these waivers or
reimbursement arrangements, performance results would have been lower.
All results shown assume reinvestment of distributions. Performance for
different share classes will vary based on differences in sales charges and
fees associated with each class. Class R and Z shares are sold at net asset
value with no Rule 12b-1 fees. Class R and Z shares have limited eligibility
and the investment minimum requirements may vary. Please see the fund's
prospectus for details.
The table does not reflect the deduction of taxes that a shareholder would pay
on fund distributions or the redemption of fund shares.

periods prior to the inception of Class R shares. The returns of Class R shares
also include the returns of the fund's Class Z shares for periods prior to the
inception of Class A shares. These returns have not been restated to reflect
any differences in expenses (such as Rule 12b-1 fees) between Class Z shares
and Class A, Class B, Class C or Class R shares, or between Class A shares and
Class B, Class C or Class R shares. If differences in expenses had been
reflected, the returns shown for Class A, Class B, Class C and Class R shares
for periods prior to the inception of Class A, Class B, Class C and Class R
shares, respectively, would have been lower. Class A shares were initially
offered on July 31, 2000, Class B and Class C shares were initially offered on
February 1, 2002, Class R shares were initially offered on January 23, 2006,
and Class Z shares were initially offered on December 5, 1978.

Understanding Your Expenses - Columbia Intermediate Bond 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 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 the 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 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 is
calculated based on the fund's actual operating expenses. 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.

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 ongoing cost of investing in a fund and do
not reflect any transaction costs, such as sales charges, redemption fees or
exchange fees.

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/or any of its affiliates not waived or
reimbursed a portion of expenses, account value 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 fund and do not reflect any
transaction costs, such as sales charges, redemption fees 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 transaction
costs were included, your costs would have been higher.

For the 12-month period that ended March 31, 2007, Class A shares of Columbia
Intermediate Bond Fund returned 6.21% without sales charge. The fund's return
was lower than the 6.59% return of its benchmark, the Lehman Brothers U.S.
Aggregate Bond Index, for the same period./1/ The fund incurs fees that the
index does not. The fund exceeded the average return of its peer group, the
Lipper Intermediate Investment Grade Debt Funds Classification, which was 6.08%
for the period./2/ Strong returns from high-yield investments helped create
this performance advantage versus the fund's peer group.

The past 12 months were a fairly stable period for the fixed-income markets.
Three months into the period, the Federal Reserve Open Market Committee (the
Fed) suspended its two-year-long string of short-term interest rate hikes, and
stayed on the sidelines for the remainder of the period. Meanwhile, inflation
remained moderate enough to bring long-term rates down slightly. The net result
was a healthy bond market. While long-term bonds tended to outperform issues
with shorter maturities, solid gains were posted at all points of the maturity
spectrum.

Steady economic growth favored corporate bonds
The national economy remained in a sweet spot characterized by strong growth
and the absence of undue inflationary pressures. The economy's steady growth
created a favorable environment for corporate bonds, consistent with a general
trend in which fixed-income investors were rewarded for assuming credit risk.
In particular, high-yield bonds were the top performing bond market sector
during the period. Our decision to overweight the high-yield sector helped the
fund's performance relative to other intermediate bond funds.

However, this reward for risk-taking did not extend to the mortgage market.
Toward the end of the period, a surge in foreclosures experienced by subprime
lenders resulted in significant losses for low-quality mortgage pools. While
the fund's exposure to subprime securities was limited, many of its mortgage
holdings lost ground as investors worried that problems could spill over to
other areas of the market.

The fund's sector decisions experienced mixed results during the period.
Positions in the financial sector helped performance for the first six months,
then hampered performance in the second half, above and beyond subprime
concerns. A decision to underweight the insurance sector also hampered
performance as major carriers delivered above-average performance after a mild
hurricane year. We may consider adding to the fund's insurance holdings because
of the balance sheet improvements created by the limited payouts of the past
year and limited subprime exposure. In addition, we believe insurers appear to
be less likely than other financial companies to be candidates for a private
equity transaction.

/1/The Lehman Brothers U.S. Aggregate Bond Index is a market value-weighted
   index that tracks the daily price, coupon, pay-downs, and total return
   performance of fixed-rate, publicly placed, dollar-denominated, and
   non-convertible investment grade debt issues with at least $250 million par
   amount outstanding and with at least one year to final maturity. 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.

Looking ahead
At the end of the period, the fund's positioning reflected our generally
positive view of the corporate bond market, supported by solid corporate
earnings and economic environment. We plan to keep our high-yield exposure in
line with our competitive peers, and would look to retain our slightly
above-average exposure to investment-grade corporate issues. The bond market
still faces an elevated risk of shareholder-friendly leveraged transactions.
Yet, we believe that such risks are generally priced into today's yields.

                                                                             5

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.
Investing in high-yield securities (commonly known as "junk" bonds) offers the
potential for high current income and attractive total return but involves
certain risks. Changes in economic conditions or other circumstances may
adversely affect a junk bond issuer's ability to make principal and interest
payments. Rising interest rates tend to lower the value of all bonds.
High-yield bonds issued by foreign entities have greater potential risks,
including less regulation, currency fluctuations, economic instability and
political developments.

as an open-end management investment company.

Investment Goal
The Fund seeks its total return by pursuing current income and opportunities
for capital appreciation.

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

Class A shares are subject to a maximum front-end sales charge of 3.25% based
on the amount of initial investment. Class A shares purchased without an
initial sales charge in accounts aggregating up to $50 million at the time of
purchase are subject to a 1.00% contingent deferred sales charge ("CDSC") if
the shares are sold within twelve months of the time of the purchase. Class B
shares are subject to a maximum CDSC of 3.00% based upon the holding period
after purchase. Class B shares will convert to Class A shares eight years after
purchase. Class C shares are subject to a 1.00% CDSC on shares sold within one
year after purchase. Class R and Class Z shares are offered continuously at net
asset value. There are certain restrictions on the purchase of Class R and
Class Z shares, as described in the Fund's prospectus.

Note 2. Significant Accounting Policies
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.

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

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 that 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.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is evaluating the impact the application of
SFAS 157 will have on the Fund's financial statement disclosures.

Security Transactions
Security transactions are accounted for on the trade date. Cost is determined
and gains (losses) are based upon the

40




Columbia Intermediate Bond Fund

specific identification method for both financial statement and federal income
tax purposes.

Futures Contracts
The Fund may invest in futures contracts to gain or reduce exposure to
particular securities or segments of the bond markets. Derivatives are
financial instruments whose values depend on, or derived from, the value of the
underlying security, index or currency. The Fund may use derivatives for both
hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to
changes in interest rates, or to offset a potential loss in one position by
establishing an opposite position. The fund typically uses derivatives in an
effort to achieve more efficiently economic exposure similar to those it could
have achieved through the purchase and sale of fixed income securities. 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, LLC ("Columbia"), the Fund's investment adviser, 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 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
Columbia has determined are creditworthy. The Fund, through its custodian,
receives delivery of underlying securities collateralizing a repurchase
agreement. Columbia is responsible for determining that 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 rolls" in which the Fund sells
securities for delivery in the current month and simultaneously contracts with
the same counterparty to repurchase similar (same type, coupon and maturity)
but not identical securities on a specified future date not exceeding 120 days.
During the roll period, the Fund loses the right to receive principal and
interest paid on the securities sold. However, the Fund would benefit to the
extent of any difference between the price received for the securities sold and
the lower forward price for the future purchase (often referred to as the
"drop") or fee income plus the interest earned on the cash proceeds of the
securities sold until the settlement date of the forward purchase. Unless such
benefits exceed the income, capital appreciation and gain or loss due to
mortgage prepayments that would have been realized on the securities sold as
part of the mortgage dollar roll, the use of this technique will diminish the
investment performance of the Fund compared with what such performance would
have been without the use of mortgage dollar rolls. All cash proceeds will be
invested in instruments that are permissible investments for the Fund. The Fund
will hold and maintain in a segregated account until the settlement date, cash
or liquid securities in an amount equal to the forward purchase price.

The Fund's policy is to record the components of mortgage dollar rolls using
"to be announced" mortgage-backed securities ("TBA Dollar Rolls"). For
financial reporting and tax purposes, the Fund treats mortgage dollar rolls as
two separate transactions, one involving the purchase of a security and a
separate transaction involving a sale. The Fund does not currently enter into
mortgage dollar rolls that are accounted for as financing.

Mortgage dollar rolls involve certain risks. If the broker-dealer to whom the
Fund sells the security becomes insolvent, the Fund's right to purchase or
repurchase the mortgage-related securities may be restricted and the instrument
which the Fund is required to repurchase may be worth less than an instrument
which the Fund originally held. Successful use of mortgage dollar rolls may
depend upon the investment advisor's ability to predict correctly interest
rates and mortgage prepayments. For these reasons, there is no

                                                                             41




Columbia Intermediate Bond Fund

March 31, 2007

assurance that mortgage dollar rolls can be successfully employed.

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 holds until
settlement date, in a segregated account, cash or liquid 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. Fee income
attributable to mortgage dollar roll transactions is accrued over the term of
the transaction.

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. 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. Although 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. The
counterparty risk exposure is, therefore, closely monitored and contracts are
only executed with high credit quality financial institutions.

Stripped Securities
Stripped mortgage-backed securities are derivative multi-class mortgage
securities structured so that one class receives most, if not all, of the
principal from the underlying mortgage assets, while the other class receives
most, if not all, of the interest and the remainder of the principal. If the
underlying mortgage assets experience greater than anticipated prepayments of
principal, the Fund may fail to fully recoup its initial investment in an
interest-only security. The market value of these securities can be extremely
volatile in response to changes in interest rates. Credit risk reflects the
risk that the Fund may not receive all or part of its principal because the
issuer or credit enhancer has defaulted on its obligation.

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 the ex-date. Dividends from net
investment income are declared daily and

42




Columbia Intermediate Bond Fund

March 31, 2007

paid monthly. Net realized capital gains, if any, are distributed at least
annually.

Indemnification
In the normal course of business, the Fund enters into contracts that contain a
variety of representations and warranties and which provide general
indemnities. The Fund's maximum exposure under these arrangements is unknown,
as this would involve future claims against the Fund. Also, under the Fund's
organizational documents and by contract, the trustees and officers of the
Trust are indemnified against certain liabilities that may arise out of their
duties to the Trust. However, based on experience, the Fund expects the risk of
loss due to these representations, warranties and indemnities to be minimal.

Note 3. Federal Tax Information
The timing and character of income and capital gain distributions are
determined in accordance with income tax regulations, which may differ from
GAAP. Reclassifications are made to the Fund's capital accounts for permanent
tax differences to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

For the year ended March 31, 2007, permanent book and tax basis differences
resulting primarily from differing treatments for discount accretion/ premium
amortization on debt securities and market discount reclasses were identified
and reclassified among the components of the Fund's net assets as follows:



                 Overdistributed Net Accumulated       Paid-In
                 Investment Income   Net Realized Loss Capital
                                                 
                 $2,768,693          $(2,768,691)      $(2)


Net investment income and net realized gains (losses), as disclosed on the
Statement of Operations, and net assets were not affected by this
reclassification.

The tax character of distributions paid during the years ended March 31, 2007
and March 31, 2006 was as follows:




                                   March 31, 2007 March 31, 2006
                Distributions paid
                from:
                                            
                 Ordinary Income*   $98,357,822    $66,652,649

*For tax purposes short-term capital gains distributions, if any, are
 considered ordinary income distributions.

As of March 31, 2007, the components of distributable earnings on a tax basis
were as follows:



                   Undistributed Undistributed Net
                   Ordinary      Long-Term     Unrealized
                   Income        Capital Gains Appreciation*
                                         
                   $4,832,862    $    --       $1,069,436


*The differences between book-basis and tax-basis net unrealized
 appreciation/depreciation are primarily due to deferral of losses from wash
 sales and differing treatment for discount accretion/premium amortization on
 debt securities.

Unrealized appreciation and depreciation at March 31, 2007, based on cost of
investments for federal income tax purposes were:



                                            
                   Unrealized appreciation     $ 19,423,096
                   Unrealized depreciation      (18,353,660)
                   Net unrealized appreciation $  1,069,436


The following capital loss carryforwards, determined as of March 31, 2007, may
be available to reduce taxable income arising from future net realized gains on
investments, if any, to the extent permitted by the Internal Revenue Code:



                  Year of Expiration Capital Loss Carryforward
                                  
                  2013                             $ 6,075,470
                  2014                               3,776,565
                  2015                               8,375,463
                                                   -----------
                  Total                            $18,227,498


Under current tax rules, certain currency and capital losses realized after
October 31 may be deferred and treated as occurring on the first day of the
following fiscal year. As of March 31, 2007, post-October capital losses of
$744,787 attributed to security transactions were deferred to April 1, 2007.

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109 (the "Interpretation"). This
Interpretation is effective on the last business day of the semiannual
reporting period for fiscal years beginning after December 15, 2006 and is to
be applied to open tax positions upon initial adoption. This Interpretation
prescribes a minimum recognition threshold and measurement method for the

                                                                             43




Columbia Intermediate Bond Fund

March 31, 2007

financial statement recognition of tax positions taken or expected to be taken
in a tax return and also requires certain expanded disclosures. Management is
evaluating the application of this Interpretation to the Fund and has not at
this time quantified the impact, if any, resulting from the adoption of this
Interpretation on the Fund's financial statements.

Note 4. Fees and Compensation Paid to Affiliates

Investment Advisory Fee
Columbia, an indirect, wholly-owned subsidiary of Bank of America Corporation
("BOA"), is the investment advisor to the Fund. Columbia receives a monthly
investment advisory fee based on the Fund's average daily net assets at the
following annual rates:



                   Average Daily Net Assets   Annual Fee Rate
                                           
                   First $1 billion                0.35%
                   $1 billion to $1.5 billion      0.30%
                   $1.5 billion to $3 billion      0.29%
                   $3 billion to $6 billion        0.28%
                   Over $6 billion                 0.27%


For the year ended March 31, 2007, the Fund's effective investment advisory fee
rate was 0.32% of the Fund's average daily net assets.

Administration Fee
Columbia provides administrative and other services to the Fund for a monthly
administration fee at the annual rate of 0.15% of the Fund's average daily net
assets.

Pricing and Bookkeeping Fees
Effective December 15, 2006, the Fund entered into a Financial Reporting
Services Agreement with State Street Bank & Trust Company ("State Street") and
Columbia (the "Financial Reporting Services Agreement") pursuant to which State
Street provides financial reporting services to the Fund. Also effective
December 15, 2006, the Fund entered into an Accounting Services Agreement with
State Street and Columbia (collectively with the Financial Reporting Services
Agreement, the "State Street Agreements") pursuant to which State Street
provides accounting services to the Fund. Under the State Street Agreements,
the Fund pays State Street an annual fee of $38,000 paid monthly plus an
additional monthly fee based on an annualized percentage rate of average daily
net assets of the Fund for the month. Under the State Street Agreements, the
combined fee payable to State Street by the Fund will not exceed $140,000
annually. The Fund also reimburses State Street for certain out-of-pocket
expenses.

Effective December 15, 2006, the Fund entered into a Pricing and Bookkeeping
Oversight and Services Agreement (the "Services Agreement") with Columbia.
Under the Services Agreement Columbia provides services related to Fund
expenses and the requirements of the Sarbanes-Oxley Act of 2002, and provides
oversight of the accounting and financial reporting services provided by State
Street. Under the Services Agreement, the Fund reimburses Columbia for
out-of-pocket expenses and direct internal costs relating to accounting
oversight and for services related to Fund expenses and the requirements of the
Sarbanes-Oxley Act of 2002.

Prior to December 15, 2006, Columbia was responsible for providing pricing and
bookkeeping services to the Fund under a pricing and bookkeeping agreement.
Under its pricing and bookkeeping agreement with the Fund, Columbia was
entitled to receive an annual fee at the same fee structure described above
under the State Street Agreements. Under separate agreements between Columbia
and State Street, Columbia delegated certain functions to State Street. As a
result of the delegation, the total fees payable under the pricing and
bookkeeping agreement (other than certain reimbursements paid to Columbia and
discussed below) were paid to State Street. The Fund also reimbursed Columbia
and State Street for out-of-pocket expenses and charges, including fees payable
to third parties for pricing the Fund's portfolio securities and direct
internal costs incurred by Columbia in connection with providing fund
accounting oversight and monitoring and certain other services.

For the year ended March 31, 2007, the Fund's effective pricing and bookkeeping
fee rate, inclusive of out-of-pocket expenses, was 0.011% of the Fund's average
daily net assets.

Transfer Agent Fee
Columbia Management Services, Inc. (the "Transfer Agent"), an affiliate of
Columbia and an indirect, wholly-owned

44




Columbia Intermediate Bond Fund

March 31, 2007

subsidiary of BOA, provides shareholder services to the Fund and has contracted
with Boston Financial Data Services ("BFDS") to serve as sub-transfer agent.
The Transfer Agent is entitled to receive a fee for its services, paid monthly,
at the annual rate of $17.00 per open account plus reimbursement of certain
sub-transfer agent fees (exclusive of BFDS fees) calculated based on assets
held in omnibus accounts and intended to recover the cost of payments to other
parties (including affiliates of BOA) for services to those accounts. The
Transfer Agent pays the fees of BFDS for services as sub-transfer agent and is
not entitled to reimbursements for such fees from the Fund. The Transfer Agent
may also retain, as additional compensation for its services, fees for wire,
telephone and redemption orders, IRA trustee agent fees and account transcript
fees due the Transfer Agent from shareholders of the Fund and credits (net of
bank charges) earned with respect to balances in accounts the Transfer Agent
maintains in connection with its services to the Fund. The Transfer Agent also
receives reimbursement for certain out-of-pocket expenses.

For the year ended March 31, 2007, the Fund's effective transfer agent fee
rate, inclusive of out-of-pocket expenses and sub-transfer agent fees, was
0.10% of the Fund's average daily net assets.

Underwriting Discounts, Service and Distribution Fees
Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal
underwriter of the Fund. For the year ended March 31, 2007, the Distributor has
retained net underwriting discounts of $11,230 on sales of the Fund's Class A
shares and net CDSC fees of $163, $211,917 and $2,596 on Class A, Class B and
Class C share redemptions, respectively.

The Fund has adopted a Rule 12b-1 plan (the "Plan") which allows the payment of
a monthly service fee to the Distributor at the annual rate of 0.25% of the
average daily net assets attributable to Class A, Class B and Class C shares of
the Fund. The Plan also requires the payment of a monthly distribution fee to
the Distributor at the annual rates of 0.10%, 0.75%, 0.75% and 0.50% of the
average daily net assets attributable to Class A, Class B, Class C and Class R
shares, respectively. The Distributor has voluntarily agreed to waive the
Class A share distribution fee. The Distributor has also voluntarily agreed to
waive a portion of the Class C share distribution fee so that it will not
exceed 0.60% annually of Class C average daily net assets. These waivers may be
modified or terminated by the Distributor at any time.

The CDSC and the distribution 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 in 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
All officers of the Fund are employees of Columbia or its affiliates and, with
the exception of the Fund's Chief Compliance Officer, receive no compensation
from the Fund. The Board of Trustees has appointed a Chief Compliance Officer
to the Fund in accordance with federal securities regulations. The Fund, along
with other affiliated funds, pays its pro-rata share of the expenses associated
with the Chief Compliance Officer. The Fund's expenses for 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 the requirements of
the Sarbanes-Oxley Act of 2002. For the year ended March 31, 2007, the Fund
paid $2,875 to Columbia for such services. This amount is included in "Other
expenses" in the Statement of Operations.

Note 5. Portfolio Information
For the year ended March 31, 2007, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $3,191,983,302 and
$2,610,517,111,

                                                                             45




Columbia Intermediate Bond Fund

March 31, 2007

respectively, of which $1,631,736,771 and $1,559,812,014, respectively, were
U.S. Government securities.

Note 6. Shares of Beneficial Interest
As of March 31, 2007, the Fund had one shareholder that held 41.9% of the
shares outstanding. The shares were beneficially owned by participant accounts
over which BOA and/or its affiliates had either sole or joint investment
discretion. Subscription and redemption activity of these accounts may have a
significant effect on the operations of the Fund.

As of March 31, 2007, the Fund had two shareholders that held 20.0% of the
shares outstanding. These shares were beneficially owned by participant
accounts over which BOA and/or its affiliates did not have investment
discretion. Subscription and redemption activity of these accounts may have a
significant effect on the operations of the Fund.

Note 7. Line of Credit
The Trust and other affiliated funds participate in a $350,000,000 committed
unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured
line of credit, both provided by State Street. Borrowings are available for
temporary or emergency purposes.

Interest on the committed line of credit is charged to each participating fund
based on the fund's borrowings at a rate per annum equal to the Federal Funds
Rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued
and apportioned among the participating funds based on their pro-rata portion
of the unutilized committed line of credit. Interest on the uncommitted line of
credit is charged to each participating fund based on the fund's borrowings at
a variable rate per annum equal to the Federal Funds Rate plus a spread, as
determined and quoted by State Street at the time of the request for a loan. A
one-time structuring fee of $30,000 is also accrued and apportioned to each
fund participating in the uncommitted line of credit based on the average net
assets of the participating funds. In addition, if the uncommitted line of
credit is extended for an additional period, an annual administration fee of
$15,000 will be charged and apportioned among the participating fund. The
commitment fee and structuring fee are included in "Other expenses" in the
Statement of Operations.

For the year ended March 31, 2007, the Fund did not borrow under this
arrangement.

Note 8. Securities Lending
The Fund commenced a securities lending program in August 2006 and may lend its
securities to certain approved brokers, dealers and other financial
institutions. Each loan is collateralized by cash, in an amount at least equal
to the market value of the securities loaned plus accrued income from the
investment of collateral. The market value of the loaned securities is
determined at the close of business of the Fund and any additional required
collateral is delivered to the Fund on the next business day. The collateral
received is invested and the income generated by the investment of the
collateral, net of any fees remitted to State Street as the lending agent and
borrower rebates, is paid to the Fund. Generally, in the event of borrower
default, the Fund has the right to use the collateral to offset any losses
incurred. In the event the Fund is delayed or prevented from exercising its
right to dispose of the collateral, there may be a potential loss to the Fund.
The Fund bears the risk of loss with respect to the investment of collateral.

Note 9. Other
During the year ended March 31, 2007, the Fund had a realized investment loss
in the amount of $135 due to a trading error. Columbia voluntarily reimbursed
the Fund for the loss.

Note 10. Other Related Party Transactions
During the year ended March 31, 2007, the Fund used Bank of America Securities,
a wholly-owned subsidiary of BOA, as a broker. No commissions were paid to Bank
of America Securities during the period.

Note 11. 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 may be less liquid to the extent that there is no
established secondary market.

Columbia Intermediate Bond Fund

March 31, 2007


Sector Focus
Companies that are in different but closely related industries are sometimes
described as being in the same sector. Although the Fund does not intend to
focus on any particular sector, at times the Fund may have a large portion of
its assets invested in a particular sector. During such times, the Fund will
have greater exposure to the economic and market events affecting such sector
than if it were more broadly invested across multiple sectors.

Legal Proceedings
On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged
into Banc of America Capital Management, LLC (now named Columbia Management
Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has
been renamed Columbia Management Distributors, Inc.) (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") on matters
relating to mutual fund trading. The SEC Order and the NYAG Settlement are
referred to collectively as the "Settlements".

Under the terms of the SEC Order, the Columbia Group 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 to reduce management fees for certain
Columbia Funds (including the former Nations Funds) and other mutual funds
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 that was developed by an independent distribution consultant
and approved by the SEC on April 6, 2007.

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 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.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation
transferred these cases and cases against other mutual fund companies based on
similar allegations to the United States District Court in Maryland for
consolidated or coordinated pretrial proceedings (the ''MDL''). Subsequently,
additional related cases were transferred to the MDL. On September 29, 2004,
the plaintiffs in the MDL filed amended and consolidated complaints. One of
these amended complaints is a putative class action that includes claims under
the federal securities laws and state common law, and that names Columbia, the
Distributor, the Trustees of the Columbia Funds, Bank of America Corporation
and others as defendants. Another of the amended complaints is a derivative
action purportedly on behalf of the Columbia Funds that asserts claims under
federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss
the claims in the pending cases. On March 1, 2006, for reasons stated in the
court's memoranda dated November 3, 2005, the U.S. District Court for the
District of Maryland granted in part and denied in part the defendants' motions
to dismiss. The court dismissed all of the class action claims pending against
the Columbia Funds Trusts. As to Columbia and the Distributor, the claims under
the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the
Investment Company Act of 1940 ("ICA") and the state law claims were dismissed.
The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of
1934 and claims under Section 36(b) of the ICA were not dismissed.

On March 21, 2005, a purported class action was filed in Massachusetts state
court alleging that certain conduct,

                                                                             47




Columbia Intermediate Bond Fund

including market timing, entitled Class B shareholders in certain Columbia
funds to an exemption from contingent deferred sales charges upon early
redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was removed to federal court
in Massachusetts and the federal Judicial Panel transferred the CDSC Lawsuit to
the MDL.

On April 4, 2006, the plaintiffs and the Columbia defendants named in the MDL,
including the Columbia Funds, entered into a term sheet containing the
principal terms of a stipulation of settlement that would settle all
Columbia-related claims in the MDL described above, including the CDSC Lawsuit.
On April 6, 2006, the U.S. District Court for the District of Maryland stayed
all actions with respect to these Columbia-related claims. The settlement is
subject to court approval.

In 2004, the Columbia Funds' adviser and distributor and certain affiliated
entities and individuals 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.
Certain Columbia Funds were named as nominal defendants. 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 purposes. 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. On November 30, 2005, the judge dismissed all claims by
plaintiffs and entered final judgment in favor of the defendants. The
plaintiffs appealed to the United States Court of Appeals for the First Circuit
on December 30, 2005. A stipulation and settlement agreement dated January 19,
2007 was filed in the First Circuit on February 14, 2007, with a joint
stipulation of dismissal and motion for remand to obtain district court
approval of the settlement. That joint motion was granted and the appeal was
dismissed. On March 6, 2007, the case was remanded to the District Court. On
May 11, 2007, the District Court entered a preliminary approval order which
granted preliminary approval of the settlement. A final settlement hearing, at
which the District Court will determine whether the proposed settlement should
be finally approved and the action dismissed on the merits with prejudice, is
scheduled for September 18, 2007. The terms of the settlement, if finally
approved, will require payments by the funds' adviser and/or its affiliates,
including payment of plaintiffs' attorneys' fees and notice to class members.
In the event that the settlement is not finally approved, the plaintiffs may
elect to go forward with their appeal and no opinion is expressed regarding the
likely outcome or financial impact of such an appeal on any fund.

Report of Independent Registered Public Accounting Firm


To the Trustees of Columbia Funds Series Trust I and the Shareholders of
Columbia Intermediate Bond Fund

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Columbia Intermediate Bond Fund
(the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and
the results of its operations, the changes in its net assets and the financial
highlights for the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management. Our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at March 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion. The
financial highlights of the Fund for the periods prior to July 1, 2003 were
audited by another independent registered public accounting firm whose report
dated August 19, 2003 expressed an unqualified opinion on those statements.

Board Consideration and Approval of Investment Advisory Agreements

The Advisory Fees and Expenses Committee of the Board of Trustees meets one or
more times annually to review the advisory agreements (collectively, the
"Agreements") of the funds for which the Trustees serve as trustees (each a
"fund") and determine whether to recommend that the full Board approve the
continuation of the Agreements for an additional one-year period. After the
Committee has made its recommendation, the full Board, including the
Independent Trustees, determines whether to approve the continuation of the
Agreements. In addition, the Board, including the Independent Trustees,
considers matters bearing on the Agreements at most of its other meetings
throughout the year and meets regularly with the heads of each investment area
within Columbia. Through the Board's Investment Oversight Committees, Trustees
also meet with selected fund portfolio managers at various times throughout the
year.

The Trustees receive and review all materials that they, their legal counsel or
Columbia, the funds' investment adviser, believe to be reasonably necessary for
the Trustees to evaluate the Agreements and determine whether to approve the
continuation of the Agreements. Those materials generally include, among other
items, (i) information on the investment performance of each fund relative to
the performance of peer groups of mutual funds and the fund's performance
benchmarks, (ii) information on each fund's advisory fees and other expenses,
including information comparing the fund's expenses to those of peer groups of
mutual funds and information about any applicable expense caps and fee
"breakpoints," (iii) information about the profitability of the Agreements to
Columbia, including potential "fall-out" or ancillary benefits that Columbia
and its affiliates may receive as a result of their relationships with the
funds and (iv) information obtained through Columbia's response to a
questionnaire prepared at the request of the Trustees by counsel to the funds
and independent legal counsel to the Independent Trustees. The Trustees also
consider other information such as (v) Columbia's financial results and
financial condition, (vi) each fund's investment objective and strategies and
the size, education and experience of Columbia's investment staffs and their
use of technology, external research and trading cost measurement tools, (vii)
the allocation of the funds' brokerage, if any, and the use of "soft"
commission dollars to pay for research products and services, (viii) Columbia's
resources devoted to, and its record of compliance with, the funds' investment
policies and restrictions, policies on personal securities transactions and
other compliance policies, (ix) Columbia's response to various legal and
regulatory proceedings since 2003 and (x) the economic outlook generally and
for the mutual fund industry in particular. In addition, the Advisory Fees and
Expenses Committee confers with the funds' independent fee consultant and
reviews materials relating to the funds' relationships with Columbia provided
by the independent fee consultant. Throughout the process, the Trustees have
the opportunity to ask questions of and request additional materials from
Columbia and to consult with independent legal counsel to the Independent
Trustees and the independent fee consultant.

The Board of Trustees most recently approved the continuation of the Agreements
at its October, 2006 meeting, following meetings of the Advisory Fees and
Expenses Committee held in August, September and October, 2006. In considering
whether to approve the continuation of the Agreements, the Trustees, including
the Independent Trustees, did not identify any single factor as determinative,
and each weighed various factors as he or she deemed appropriate. The Trustees
considered the following matters in connection with their approval of the
continuation of the Agreements:

The nature, extent and quality of the services provided to the funds under the
Agreements. The Trustees considered the nature, extent and quality of the
services provided by Columbia and its affiliates to the funds and the resources
dedicated to the funds by Columbia and its affiliates. Among other things, the
Trustees considered (i) Columbia's ability (including its personnel and other
resources, compensation programs for personnel involved in fund management,
reputation and other attributes) to attract and retain highly qualified
research, advisory and supervisory investment professionals; (ii) the portfolio
management services provided by those investment professionals; and (iii) the
trade execution services provided on behalf of the funds. For each fund, the
Trustees also considered the benefits to shareholders of investing in a mutual
fund that is part of a family of funds offering exposure to a variety of asset
classes and investment disciplines and providing a variety of fund and
shareholder services. After reviewing those and related factors, the Trustees
concluded, within the context of their overall conclusions regarding each of
the Agreements, that the nature, extent and quality of services provided
supported the continuation of the Agreements.

54







Investment performance of the funds and Columbia. The Trustees reviewed
information about the performance of each fund over various time periods,
including information prepared by an independent third party that compared the
performance of each fund to the performance of peer groups of mutual funds and
performance benchmarks. The Trustees also reviewed a description of the third
party's methodology for identifying each fund's peer group for purposes of
performance and expense comparisons. The Trustees also considered additional
information that the Advisory Fees and Expenses Committee requested from
Columbia relating to funds that presented relatively weaker performance and/or
relatively higher expenses.

In the case of each fund whose performance lagged that of a relevant peer group
for certain (although not necessarily all) periods, the Trustees concluded that
other factors relevant to performance were sufficient, in light of other
considerations, to warrant continuation of the fund's Agreements. Those factors
varied from fund to fund, but included one or more of the following: (i) that
the fund's performance, although lagging in certain recent periods, was
stronger over the longer term; (ii) that the underperformance was attributable,
to a significant extent, to investment decisions that were reasonable and
consistent with the fund's investment strategy and policies and that the fund
was performing as expected, given these investment decisions, market conditions
and the fund's investment strategy; (iii) that the fund's performance was
competitive when compared to other relevant performance benchmarks or peer
groups; (iv) that Columbia had taken or was taking steps designed to help
improve the fund's investment performance, including, but not limited to,
replacing portfolio managers or modifying investment strategies; and (v) that
the fund was proposed to be reorganized into another fund, and that such
reorganization would result in a reduction in fund expenses.

The Trustees also considered Columbia's performance and reputation generally,
the funds' performance as a fund family generally, and Columbia's historical
responsiveness to Trustee concerns about performance and Columbia's willingness
to take steps intended to improve performance.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
performance of each fund and Columbia was sufficient, in light of other
considerations, to warrant the continuation of the Agreement(s) pertaining to
that fund.

The costs of the services provided and profits realized by Columbia and its
affiliates from their relationships with the funds. The Trustees considered the
fees charged to the funds for advisory services as well as the total expense
levels of the funds. That information included comparisons (provided by
management and by an independent third party) of each fund's advisory fees and
total expense levels to those of the fund's peer groups and information about
the advisory fees charged by Columbia to comparable institutional accounts. In
considering the fees charged to those accounts, the Trustees took into account,
among other things, management's representations about the differences between
managing mutual funds as compared to other types of accounts, including
differences in the services provided, differences in the risk profile of such
business for Columbia, and the additional resources required to manage mutual
funds effectively. In evaluating each fund's advisory fees, the Trustees also
took into account the demands, complexity and quality of the investment
management of the fund. The Trustees considered existing advisory fee
breakpoints, and Columbia's use of advisory fee waivers and expense caps, which
benefited a number of the funds. The Trustees also noted management's stated
justification for the fees charged to the funds, which included information
about the investment performance of the funds and the services provided to the
funds. The Trustees also considered the compensation directly or indirectly
received by Columbia and its affiliates from their relationships with the
funds. The Trustees reviewed information provided by management as to the
profitability to Columbia and its affiliates of their relationships with each
fund, and information about the allocation of expenses used to calculate
profitability. When reviewing profitability, the Trustees also considered court
cases in which adviser profitability was an issue in whole or in part, the
performance of the relevant funds, the expense level of each fund, and whether
Columbia had implemented breakpoints and/or expense caps with respect to the
fund.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
advisory fees charged to each fund, and the related profitability to Columbia
and its affiliates of their relationships with the fund, supported the
continuation of the Agreement(s) pertaining to that fund.

                                                                             55







Economies of Scale. The Trustees considered the existence of any economies of
scale in the provision by Columbia of services to each fund, to groups of
related funds, and to Columbia's investment advisory clients as a whole and
whether those economies were shared with the funds through breakpoints in the
investment advisory fees or other means, such as expense waivers/reductions and
additional investments by Columbia in investment, trading and compliance
resources. The Trustees noted that many of the funds benefited from
breakpoints, expense caps, or both. In considering those issues, the Trustees
also took note of the costs of the services provided (both on an absolute and a
relative basis) and the profitability to Columbia and its affiliates of their
relationships with the funds, as discussed above.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
extent to which economies of scale were shared with the funds supported the
continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but
were not limited to the following:

.. the extent to which each fund had operated in accordance with its investment
  objective and investment restrictions, the nature and scope of the compliance
  programs of the funds and Columbia and the compliance-related resources that
  Columbia and its affiliates were providing to the funds;

.. the nature, quality, cost and extent of administrative and shareholder
  services performed by Columbia and its affiliates, both under the Agreements
  and under separate agreements for the provision of transfer agency and
  administrative services;

.. so-called "fall-out benefits" to Columbia and its affiliates, such as the
  engagement of its affiliates to provide distribution, brokerage and transfer
  agency services to the funds, and the benefits of research made available to
  Columbia by reason of brokerage commissions generated by the funds'
  securities transactions, as well as possible conflicts of interest associated
  with those fall-out and other benefits, and the reporting, disclosure and
  other processes in place to disclose and monitor those possible conflicts of
  interest; and

.. the draft report provided by the funds' independent fee consultant, which
  included information about and analysis of the funds' fees, expenses and
  performance.

Based on their evaluation of all factors that they deemed to be material,
including those factors described above, and assisted by the advice of
independent counsel and the independent fee consultant, the Trustees, including
the Independent Trustees, approved the continuance of each of the Agreements
through October 31, 2007.

Summary of Management Fee Evaluation by Independent Fee Consultant

Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between
the Office of Attorney General of New York State and Columbia Management
Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006

  I. Overview

Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors,
Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's
Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates
that CMA may manage or advise a Columbia Fund ("Fund" and together with all
such funds or a group of such funds as the "Funds") only if the Independent
Members of the Fund's Board of Trustees (such Independent Members of the Fund's
Board together with the other members of the Fund's Board, referred to as the
"Trustees") appoint a Senior Officer or retain an Independent Fee Consultant
("IFC") who is to manage the process by which proposed management fees are
negotiated. The AOD further stipulates that the Senior Officer or IFC is to
prepare a written annual evaluation of the fee negotiation process.

On September 14, 2006, the Independent Members of the Funds' Boards retained me
as IFC for the Funds. In this capacity, I have prepared the second annual
written evaluation of the fee negotiation process. I am successor to the first
IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed
to the second annual written evaluation until his resignation as IFC in August
2006 to become Director of the Division of Market Regulation at the U.S.
Securities and Exchange Commission./2/

A. Role of the Independent Fee Consultant
The AOD charges the IFC with "managing the process by which proposed management
fees...to be charged the Columbia Fund are negotiated so that they are
negotiated in a manner which is at arms' length and reasonable and consistent
with this Assurance of Discontinuance." In this role, the IFC does not replace
the Trustees in negotiating management fees with CMA, and the IFC does not
substitute his or her judgment for that of the Trustees about the
reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a
Columbia Fund only if the reasonableness of the proposed management fees is
determined by the Board of Trustees...using...an annual independent written
evaluation prepared by or under the direction of...the Independent Fee
Consultant."

B. Elements Involved in Managing the Fee Negotiation Process
Managing the fee negotiation process has three elements. One involves reviewing
the information provided by CMG to the Trustees for evaluating the proposed
management fees and augmenting that information, as necessary, with additional
information from CMG or other sources and with further analyses of the
information and data. The second element involves reviewing the information and
analysis relative to at least the following six factors set forth in the AOD:

1.The nature and quality of CMA's services, including the Fund's performance;

2.Management fees (including any components thereof) charged by other mutual
  fund companies for like services;

3.Possible economies of scale as the Fund grows larger;

4.Management fees (including any components thereof) charged to institutional
  and other clients of CMA for like services;

5.Costs to CMA and its affiliates of supplying services pursuant to the
  management fee agreements, excluding any intra-corporate profit; and

6.Profit margins of CMA and its affiliates from supplying such services.

1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which
 also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds'
 transfer agent. Before the date of this report, CMA merged into an affiliated
 entity, Banc of America Capital Management, LLC, which was renamed Columbia
 Management Advisors, LLC and which carries on the business of CMA. CFD also
 has been renamed Columbia Management Distributors, Inc.
2I am an independent economic consultant. From August 2005 until August 2006, I
 provided support to Mr. Sirri as an independent consultant. From 1994 to 2004,
 I was Chief Economist at the Investment Company Institute. Earlier, I was
 Section Chief and Assistant Director at the Federal Reserve Board and
 Professor of Economics at Oklahoma State University. I have no material
 relationship with Bank of America or CMG, aside from serving as IFC, and I am
 aware of no material relationship with any of their affiliates. To assist me
 with the report, I engaged NERA Economic Consulting, an independent consulting
 firm that has had extensive experience in the mutual fund industry. I also
 have retained Willkie Farr & Gallagher LLP as counsel to advise me in
 connection with the report.

                                                                             57







The final element involves providing the Trustees with a written evaluation of
the above factors as they relate to the fee negotiation process.

C. Organization of the Annual Evaluation
The 2006 annual evaluation focuses on the six factors and contains a section
for each factor except that CMA's costs and profits from managing the Funds
have been combined into a single section. In each section, the discussion of
the factor considers and analyzes the available data and other information as
they bear upon the fee negotiation process. If appropriate, the discussion in
the section may point out certain aspects of the proposed fees that may warrant
particular attention from the Trustees. The discussion also may suggest other
data, information, and approaches that the Trustees might consider
incorporating into the fee negotiation process in future years.

In addition to a discussion of the six factors, the report reviews the status
of recommendations made in the 2005 IFC evaluation. The 2006 report also
summarizes the findings with regard to the six factors and contains a summary
of recommendations for possible enhancements to the process.

  II. Status of 2005 Recommendations

The 2005 IFC evaluation contains recommendations aimed at enhancing the
evaluation of proposed management fees by Trustees. The section summarizes
those recommendations and includes my assessment of the response to the
recommendations.

1.  Recommendation: Trustees should consider requesting more analytical work
    from CMG in the preparation of future 15(c) materials.

    Status: CMG has provided additional analyses to the Trustees on economies
    of scale, a comparative analysis of institutional and retail management
    fees, management fee breakpoints, risk-adjusted performance, fee waivers
    and expense reimbursements, and CMG's costs and profitability.

2.  Recommendation: Trustees may wish to consider whether CMG should continue
    expanding the use of Morningstar or other third party data to supplement
    CMG's fee and performance analysis that is now based primarily on Lipper
    reports.

    Status: CMG has used data from Morningstar Inc. to compare with data from
    Lipper Inc. ("Lipper") in performing the Trustees' screening procedures.

3.  Recommendation: Trustees should consider whether...the fund-by-fund
    screen...should place comparable emphasis on both basis point and quintile
    information in their evaluation of the funds...Also, the Trustees should
    consider incorporating sequences of one year performance into a
    fund-by-fund screen.

    Status: CMG has not provided Trustees with results of the screening process
    using percentiles. CMG has provided Trustees with information on the
    changes in performance and expenses between 2005 and 2006 and data on
    one-year returns.

4.  Recommendation: Given the volatility of fund performance, the Trustees may
    want to consider whether a better method exists than th[e] fee waiver
    process to deal with fund underperformance.

    Status: It is my understanding that the Trustees have determined to address
    fund underperformance not only through fee waivers and expense caps but
    also through discussions with CMG regarding the sources of
    underperformance. CMG has provided Trustees with an analysis of the
    relationship between breakpoints, expense reimbursements, and fee waivers.

5.  Recommendation: [Seventy-one] percent of funds [have] yet to reach their
    first management fee breakpoint... Trustees may wish to consider whether
    the results of my ongoing economies-of-scale work affects the underlying
    economic assumptions reflected in the existing breakpoint schedules.

    Status: CMG has prepared a memo for the Trustees discussing its views on
    the nature and sharing of potential economies of scale. The memo discuses
    CMG's view that economies of scale arise at the complex level rather than
    the fund level. The memo also describes steps, including the introduction
    of breakpoints, taken to share economies of scale with shareholders. CMG's
    analysis, however, does not discuss specific sources of economies of scale
    and does not link breakpoints to economies of scale that might be realized
    as the Funds' assets increase.

58







6.  Recommendation: Trustees should continue working with management to address
    issues of funds that demonstrate consistent or significant underperformance
    even if the fee levels for the funds are low.

    Status: Trustees monitor performance on an ongoing basis.

  III. Findings

A. General
1.  Based upon my examination of the available information and the six factors,
    I conclude that the Trustees have the relevant information necessary to
    evaluate the reasonableness of the proposed management fees for the Funds.
    CMG has provided the Trustees with relevant materials on the six factors
    through the 15(c) contract renewal process and in materials prepared for
    review at Board and Committee meetings.

2.  In my view, the process by which the proposed management fees of the Funds
    have been negotiated in 2006 thus far has been, to the extent practicable,
    at arms' length and reasonable and consistent with the AOD.

B. Nature and Quality of Services, Including Performance
3.  The performance of the Funds has been relatively strong, especially that of
    fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance
    periods, over 60 percent of the funds have ranked in the top three
    performance quintiles.

4.  The performance of the equity Funds overall, though less concentrated in
    the top two quintiles than the fixed income Funds, improved in 2006
    relative to that in 2005. The fixed-income funds maintained the relatively
    high performance level of 2005 in 2006.

5.  The Funds' overall performance adjusted for risk was significantly stronger
    than performance unadjusted for risk. Domestic and international equity
    funds, in particular, moved to higher relative performance rankings after
    adjusting for risk.

6.  The procedure used to construct the performance universe in which each
    Fund's performance is ranked relative to comparable funds may bias a Fund's
    ranking upward within that universe. The bias occurs because the
    performance ranking procedure includes all share classes of multi-class
    funds in the universe and because the procedure ranks either no-load or A
    share classes of the Funds. No-load and A share classes generally have
    lower total expenses than B and C shares (owing to B and C shares having
    higher distribution/service fees) and thus, given all else, would
    outperform many of B and C share classes included in the universe. A
    preliminary analysis that adjusts for the bias results in a downward
    movement in the relative performance for the Funds but does not change the
    general finding that the Funds' performance has been strong relative to
    comparable funds.

C. Management Fees Charged by Other Mutual Fund Companies
7.  The Funds' management fees and total expenses are generally low relative to
    those of their peers. At least 56 percent of the Funds are in the first or
    second quintiles with the lowest fees and expenses and nearly three fourths
    or more in the first three quintiles. Equity Funds are more highly
    concentrated in the first three quintiles than fixed-income Funds.

8.  The fee and expense rankings as whole are similar to those in 2005 in that
    the majority of funds are ranked in the top quintiles. Nonetheless, a
    number of individual funds experienced a change in ranking between 2005 and
    2006. This fund-level instability may reflect sensitivity of rankings to
    the composition of the comparison groups, as the membership of the peer
    groups typically changed substantially between the two years.

9.  The Liberty Money Market Fund VS appears to have a higher management fee
    structure than that of other Columbia money market funds of comparable
    asset size.

                                                                             59







D. Trustees' Fee and Performance Evaluation Process
10. The Trustees' evaluation process identified 21 funds in 2006 for further
    review based upon their relative performance or expenses. Seventeen of
    these funds had been subject to review in 2004 or 2005.

E. Potential Economies of Scale
11. CMG has prepared a memo for the Trustees containing its views on the
    sources and sharing of potential economies of scale. CMG views economies of
    scale as arising at the complex level and would regard estimates of scale
    economies for individual funds as unreliable. CMG has not, however,
    identified specific sources of economies of scale nor has it provided any
    estimates of the magnitude of any economies of scale. In the memo, CMG also
    describes measures taken by the Trustees and CMG that seek to share any
    potential economies of scale through breakpoints in management fee
    schedules, expense reimbursements, fee waivers, enhanced shareholder
    services, fund mergers, and operational consolidation. These measures,
    although of significant benefit to shareholders, have not been directly
    linked in the memo to the existence, sources, and magnitude of economies of
    scale.

F. Management Fees Charged to Institutional Clients
12. CMG has provided Trustees with comparisons of mutual fund management fees
    and institutional fees based upon standardized fee schedules and upon
    actual fees. Based upon the information, institutional fees are generally
    lower than the Funds' management fees. This pattern is consistent with the
    economics of the two financial products. Data are not available, however,
    on actual institutional fees at other money managers. Thus, it is not
    possible to determine the extent to which differences between the Funds'
    management fees and institutional fees are consistent with those seen
    generally in the marketplace.

G. Revenues, Expenses, and Profits
13. The financial statements and the methodology underlying their construction
    generally form a sufficient basis for Trustees to evaluate the expenses and
    profitability of the Funds.

  IV. Recommendations

A. Performance
1.  Trustees may wish to consider incorporating risk adjusted measures in their
    evaluation of performance. CMG has begun to prepare reports for the
    Trustees with risk adjustments, which could form the basis for formally
    including the measures in the 15(c) materials. To this end, Trustees may
    wish to have CMG prepare documents explaining risk adjustments and
    describing their advantages and disadvantages.

2.  Trustees may wish to consider having CMG evaluate the sensitivity of
    performance rankings to the design of the universe. The preliminary
    analysis contained in the evaluation suggests that the method employed by
    Lipper, the source of performance rankings used by the Trustees, may bias
    performance rankings upward.

B. Economies of Scale
3.  Trustees may wish to consider having CMG extend its analysis of economies
    of scale by examining the sources of such economies, if any. Identification
    of the sources may enable the Trustees and CMG to gauge their magnitude. It
    also may enable the Trustees and CMG to build upon past work on
    standardized fee schedules so that the schedules themselves are consistent
    with any economies of scale and their sources. Finally, an extension of the
    analysis may enable the Trustees and CMG to develop a framework that
    coordinates the use of fee waivers and expense caps with the standard fee
    schedules and with any economies of scale and their sources.

C. Institutional Fees
4.  Trustees may wish to consider encouraging CMG to build further upon its
    expanded analysis of institutional fees by refining the matching of
    institutional accounts with mutual funds, by dating the establishment of
    each institutional account, and by incorporating other accounts, such as
    subadvisory relationships, trusts, offshore funds, and separately managed
    accounts into the analysis.

60







D. Profitability
5.  Trustees may wish to consider requesting that CMG expand the reporting of
    revenues and expenses to include more line-item detail for management and
    administration, transfer agency, fund accounting, and distribution.

6.  Trustees may wish to consider requesting that CMG provide a statement of
    its operations in the 15(c) materials.

7.  Trustees may wish to consider the treatment of the revenue sharing with the
    Private Bank of Bank of America in their review of CMG's profitability.

Respectfully submitted,
John D. Rea

                                                                             61




Appendix

Sources of Information Used in the Evaluation

The following list generally describes the sources and types of information
that were used in preparing this report.

1.  Performance, management fees, and expense ratios for the Funds and
    comparable funds from other fund complexes from Lipper and CMG. The sources
    of this information were CMG and Lipper;

2.  CMG's expenses and profitability obtained directly from CMG;

3.  Information on CMG's organizational structure;

4.  Profitability of publicly traded asset managers from Lipper;

5.  Interviews with CMG staff, including members of senior management, legal
    staff, heads of affiliates, portfolio managers, and financial personnel;

6.  Documents prepared by CMG for Section 15(c) contract renewals in 2005 and
    2006;

7.  Academic research papers, industry publications, professional materials on
    mutual fund operations and profitability, and SEC releases and studies of
    mutual fund expenses

8.  Interviews with and documents prepared by Ernst & Young LLP in its review
    of the Private Bank Revenue Sharing Agreement;

9.  Discussions with Trustees and attendance at Board and committee meetings
    during which matters pertaining to the evaluation were considered.

In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data
management and analysis. NERA has extensive experience in the mutual fund
industry that provides unique insights and special knowledge pertaining to my
independent analysis of fees, performance, and profitability. I have also
retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher
LLP as outside counsel to advise me in connection with my evaluation.

Finally, meetings and discussions with CMG staff were informative. My
participation in Board and committee meetings in which Trustees and CMG
management discussed issues relating to management contracts were of great
benefit to the preparation of the evaluation.

                     Dear Shareholder:
                     Investing is a long-term process and we are pleased that
                     you have chosen to include the Columbia family of funds in
                     your overall financial plan.

                     Your financial advisor can help you establish an
                     appropriate investment portfolio and periodically review
                     that portfolio. A well balanced portfolio is one of the
                     keys to successful long-term investing. Your portfolio
                     should be diversified across different asset classes and
                     market segments and your chosen asset allocation should be
                     appropriate for your investment goals, risk tolerance and
                     time horizons.

However, creating an investment strategy is not a one-step process. From time
to time, you'll need to re-evaluate your strategy to determine whether your
investment needs have changed. Most experts recommend giving your portfolio a
"check-up" every year.

As you begin your portfolio check-up, consider whether you have experienced any
major life events since the last time you assessed your portfolio. You may need
to tweak your strategy if you have:

   . Gotten married or divorced
   . Added a child to your family
   . Made a significant change in employment
   . Entered or moved significantly closer to retirement
   . Experienced a serious illness or death in the family
   . Taken on or paid off substantial debt

It's important to remember that over time, performance in different market
segments will fluctuate. These shifts can cause your portfolio balance to drift
away from your chosen asset allocation. A periodic portfolio check-up can help
make sure your portfolio stays on track. Remember that asset allocation does
not ensure a profit or guarantee against loss.

You'll also want to analyze the individual investments in your portfolio. Of
course, performance should be a key factor in your analysis, but it's not the
only factor to consider. Make sure the investments in your portfolio line up
with your overall objectives and risk tolerance. Be aware of changes in
portfolio management and pay special attention to any funds that have made
significant shifts in their investment strategy.

We hope this information will help you, in working with your financial advisor,
to stay on track to reach your investment goals. Thank you for your business
and for your continued confidence in Columbia Funds.

Sincerely,

/s/ Christopher L. Wilson

Economic Update - Columbia U.S. Treasury Index Fund


  Summary

  For the 12-month period ended March 31, 2007

 . Investment-grade bonds rebounded as yields declined, lifting the Lehman
   Brothers U.S. Aggregate Bond Index to a respectable return. High-yield
   bonds, as measured by the Merrill Lynch U.S. High Yield, Cash Pay Index, led
   the US fixed-income markets.


                                               
                    Lehman                                         Merrill Lynch
                     Index                                             Index

 . The broad US stock market, as measured by the S&P 500 Index, returned
   11.83%. Stock markets outside the United States were even stronger, as
   measured by the MSCI EAFE Index.

                    11.83%                                            20.20%


  The Lehman Brothers U.S. Aggregate Bond Index is a market value-weighted
  index that tracks the daily price, coupon, pay-downs, and total return
  performance of fixed-rate, publicly placed, dollar-denominated, and
  non-convertible investment grade debt issues with at least $250 million par
  amount outstanding and with at least one year to final maturity.
  The Merrill Lynch U.S. High Yield, Cash Pay Index tracks the performance of
  non-investment-grade corporate bonds.
  The S&P 500 Index tracks the performance of 500 widely held,
  large-capitalization US stocks.
  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.
  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.
US economic growth advanced at a modest pace during the 12-month period that
began April 1, 2006 and ended March 31, 2007. A weak housing market weighed on
the economy throughout the period, with few signs that relief was imminent.
Energy prices trended downward, but rose again late in the period, and core
inflation moved higher. Yet, many economic indicators remained positive. Job
growth, for example, was relatively strong, as the labor markets added an
average of 164,000 new jobs each month over the period and the unemployment
rate declined to 4.4%. Personal income rose and consumer spending continued to
expand, albeit at a slower pace as the period wore on. Against this backdrop,
economic growth averaged around 2.2% for the 12-month period.

Between April and June 2006, the Federal Reserve Board (the Fed) raised a key
short-term interest rate, the federal funds rate, twice -- to 5.25%. But after
its June meeting, the Fed turned cautious in the face of slower economic growth
and held the federal funds rate steady. Investors reacted favorably to the
prospect of stable or lower interest rates and fueled a rally that moved stock
prices higher and gave a boost to the bond market as well.

Bonds bounced back
Although bond yields moved higher early in the period, most segments of the US
bond market delivered respectable returns, as prices rose and yields declined
in reaction to the Fed's mid-year decision to put further short-term rate
increases on hold. The yield on the 10-year US Treasury note/1/, a bellwether
for the bond market, ended the 12-month period at 4.63% -- somewhat lower than
where it started. In this environment, the Lehman Brothers U.S. Aggregate Bond
Index returned 6.59%. High-yield bonds led the US fixed-income markets,
reflecting investor confidence about the overall resilience of the economy
despite its slower pace of growth. The Merrill Lynch U.S. High Yield, Cash Pay
Index returned 11.45%.

Despite late set-back, stocks moved solidly higher
Stock prices rose at an above-average pace during the 12-month period covered
by this report. The S&P 500 Index, a broad measure of common stock performance,
rose 11.83%. Large-cap stocks staged a comeback against small- and mid-cap
stocks, as measured by their respective Russell indices. Foreign stock markets
were even stronger than the US market. The MSCI EAFE Index, which tracks stock
market performance in industrialized countries outside the United States and
Canada returned 20.20%, despite a volatile stretch late in the period when the
US and many foreign stock markets retreated in response to a sharp decline in
the Chinese market and other market-specific factors.

The chart above shows the growth in value of a hypothetical $10,000 investment
in Class A shares of Columbia U.S. Treasury Index Fund during the stated
period, and does not reflect the deduction of taxes that a shareholder would
pay on fund distributions or redemption of fund shares. The Citigroup Bond U.S.
Treasury Index is an index composed of all US Treasury notes and bonds with
remaining maturities of at least one year and outstanding principal of at least
$25 million that are included in the Citigroup Broad Investment-Grade Bond
Index. Securities in the Citigroup Bond U.S. Treasury Index are weighted by
market value, that is, the price per bond or note multiplied by the number of
bonds or notes outstanding. 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.

The "with sales charge" returns include the maximum initial sales charge of
4.75% for Class A shares, the maximum contingent deferred sales charge of 5.00%
in the first year, declining to 1.00% in the sixth year, and eliminated
thereafter for Class B shares and 1.00% for Class C shares for the first year
only. The "without sales charge" returns do not include the effect of sales
charges. If they had, returns would be lower.
Performance results reflect any waivers or reimbursements of fund expenses by
the investment advisor and/or any of its affiliates. Absent these waivers or
reimbursement arrangements, performance results would have been lower.
All results shown assume reinvestment of distributions. Performance for
different share classes will vary based on differences in sales charges and
fees associated with each class. Class Z shares are sold at net asset value
with no Rule 12b-1 fees. Class Z shares have limited eligibility and the
investment minimum requirements may vary. Please see the fund's prospectus for
details.
The table does not reflect the deduction of taxes that a shareholder would pay
on fund distributions or the redemption of fund shares
The returns of Class A, Class B and Class C shares include returns of the
fund's Class Z shares (the oldest existing fund share class) for periods prior
to the inception of Class A, Class B and Class C shares, respectively. These
returns have not been restated to reflect any expense differential (e.g. Rule
12b-1 fees) between Class Z shares and Class A, Class B or Class C shares. If
differences in expenses had been reflected, the returns shown for Class A,
Class B and Class C shares for periods prior to the inception of Class A, Class
B and Class C shares, respectively, would have been lower. Class A, Class B and
Class C shares were initially offered on November 25, 2002 and Class Z shares
were initially offered on June 4, 1991.

Understanding Your Expenses - Columbia U.S. Treasury Index 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 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 the 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 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 is
calculated based on the fund's actual operating expenses. 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.

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 ongoing cost of investing in a fund and do
not reflect any transaction costs, such as sales charges, redemption fees or
exchange fees.

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/or any of its affiliates not waived or
reimbursed a portion of expenses, account value 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 fund and do not reflect any
transaction costs, such as sales charges, redemption fees 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 transaction
costs were included, your costs would have been higher.

For the 12-month period that ended March 31, 2007, Columbia U.S. Treasury Index
Fund's Class A shares returned 5.30% without sales charge. The fund's Class Z
shares returned 5.53%. The fund's benchmark, the Citigroup Bond U.S. Treasury
Index, posted a total return of 5.85% over the same period./1/ Fees generally
accounted for the difference between the fund's return and that of the index.
The fund incurs expenses while the index does not. The fund's return was
slightly lower than the average return of its peer group, the Lipper General
U.S. Treasury Funds Category, which was 5.69%./2/

A steady Fed helped raise Treasury bond prices
Treasury bond prices moved slightly higher for the 12-month period, but not in
a straight line. During the first three months of the reporting period, the
bond market retreated sharply as fixed-income investors began to fear that the
Federal Reserve Board (the Fed) was prepared to continue to raise short-term
interest rates. However, when the Fed held the line on additional rate hikes at
its June 2006 meeting, bond prices moved higher before settling into a fairly
narrow trading range for the remainder of the period.

Flight to quality late in the period
For most of the 12-month reporting period, investors were rewarded for taking
on credit risk. Investment-grade corporate bonds outperformed comparable
Treasury securities by nearly a full percentage point. However, this trend
reversed itself during the first quarter of 2007, when the credit scares
experienced by the subprime mortgage market created a flight-to-quality mindset
that enabled Treasuries to keep pace with corporates.

Yields declined as prices rose
During the year, the average yield to maturity on the fund declined from 4.9%
to 4.7%, consistent with a slight decline in interest rates across most
maturity ranges. The fund's average maturity also declined from 7.1 years to
6.9 years because we reduced the fund's holdings in the 10+ year maturity range
by approximately five percentage points and made a corresponding increase in
the one-to-five-year range.

At the end of the period, bond yields were essentially flat across the maturity
spectrum, with 30-year securities yielding only a quarter of a percentage point
more than two-year securities. We believe this yield pattern suggests that the
market is anticipating a slight decrease in short-term rates by the end of the
year. While an unexpectedly weak economy could, in theory, force the Fed to
lower rates more aggressively, we believe short rates and the overall bond
market will be fairly stable in the year ahead.

  Management style is determined by Columbia Management and is based on the
  investment strategy and process as outlined in the fund's prospectus.


Summary
.. For the 12-month period that ended March 31, 2007, the fund's class A shares
  returned 5.30% without sales charge.

.. The Federal Reserve Board kept short-term interest rates steady after June
  2006 and Treasury yields remained essentially flat across all maturities.

.. The fund shortened its maturity profile during the year, to stay in line with
  the pattern of new issuance within the Treasury market.

Portfolio Management
David Lindsay has managed the Columbia U.S. Treasury Index Fund since July 1994
and has been with the advisor or its predecessors or affiliate organizations
since 1986.


Portfolio holdings and characteristics are subject to change and may not be
representative of current holdings and characteristics. The outlook for this
fund may differ from that presented for other Columbia Funds. Performance for
different classes of shares will vary based on differences in sales charges and
fees associated with each class. For standardized performance, please refer to
the Performance Information page.
The value of the fund may be affected by interest rate changes and the
creditworthiness of issuers held in the fund. When interest rates go up, bond
prices typically drop, and vice versa.
The fund is subject to indexing risk; Your investment in the fund will
typically decline in value when its index declines. Since the fund is designed
to track its index, the fund cannot purchase other securities that may help
offset declines in its index. In addition, because the fund may not hold all
issues included in its index, may not always be fully invested, and bears
transaction costs and expenses, the fund's performance may fail to match the
performance of its index, after taking expenses into account. Security prices
in a market, sector or industry may fall, reducing the value of your
investment. Fund shares are not guaranteed or backed by the US government or
any agency.

Notes to Financial Statements - Columbia U.S. Treasury Index Fund

March 31, 2007

Note 1. Organization
Columbia U.S. Treasury Index Fund (the "Fund"), a series of Columbia Funds
Series Trust I (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 to provide investment results that, before deduction of
operating expenses, match the price and yield performance of the Citigroup Bond
U.S. Treasury Index.

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 subject to a maximum front-end sales charge of 4.75% based
on the amount of initial investment. Class B shares are subject to a maximum
contingent deferred sales charge ("CDSC") of 5.00% based upon the holding
period after purchase. Class B shares will convert to Class A shares eight
years after purchase. 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
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.

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 that 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.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued. SFAS 157 is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is evaluating the impact the application of
SFAS 157 will have on the Fund's financial statement disclosures.

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
Columbia Management Advisors, LLC ("Columbia") has determined are creditworthy.
The Fund, through its custodian, receives delivery of underlying securities
collateralizing a repurchase agreement. Columbia is responsible for determining
that 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

Columbia U.S. Treasury Index Fund

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.

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

Indemnification
In the normal course of business, the Fund enters into contracts that contain a
variety of representations and warranties and which provide general
indemnities. The Fund's maximum exposure under these arrangements is unknown,
as this would involve future claims against the Fund. Also, under the Fund's
organizational documents and by contract, the trustees and officers of the
Trust are indemnified against certain liabilities that may arise out of their
duties to the Trust. However, based on experience, the Fund expects the risk of
loss due to these representations, warranties and indemnities to be minimal.

Note 3. Federal Tax Information
The timing and character of income and capital gain distributions are
determined in accordance with income tax regulations, which may differ from
GAAP. Reclassifications are made to the Fund's capital accounts for permanent
tax differences to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

For the year ended March 31, 2007, permanent book and tax basis differences
resulting primarily from differing treatments for discount accretion/premium
amortization on debt securities and market discount reclasses were identified
and reclassified among the components of the Fund's net assets as follows:



                      Overdistributed Accumulated
                      Net Investment  Net Realized Paid-In
                      Income          Loss         Capital
                                             
                      $760,089        $(760,089)   $--


Net investment income and net realized gains (losses), as disclosed on the
Statement of Operations, and net assets were not affected by this
reclassification.

The tax character of distributions paid during the years ended March 31, 2007
and March 31, 2006 was as follows:



                                          March 31,  March 31,
                                          2007       2006
                 Distributions paid from:
                                               
                     Ordinary Income*     $6,451,677 $6,344,379

*For tax purposes short-term capital gains distributions, if any, are
 considered ordinary income distributions.

                                                                             17




Columbia U.S. Treasury Index Fund

March 31, 2007


As of March 31, 2007, the components of distributable earnings on a tax basis
were as follows:



                   Undistributed Undistributed Net
                   Ordinary      Long-term     Unrealized
                   Income        Capital Gains Depreciation*
                                         
                   $198,020      $--           $(157,859)

*The differences between book-basis and tax-basis net unrealized depreciation
 are primarily due to deferral of losses from wash sales and differing
 treatment for discount accretion/premium amortization on debt securities.

Unrealized appreciation and depreciation at March 31, 2007, based on cost of
investments for federal income tax purposes was:



                                             
                    Unrealized appreciation     $  1,724,575
                    Unrealized depreciation      (1,882,434)
                    Net unrealized depreciation $  (157,859)


The following capital loss carryforwards, determined as of March 31, 2007, may
be available to reduce taxable income arising from future net realized gains on
investments, if any, to the extent permitted by the Internal Revenue Code:



                  Year of Expiration Capital Loss Carryforward
                                  
                  2009                             $   388,326
                  2013                                 151,924
                  2014                                 790,826
                  2015                               1,853,769
                  Total                            $ 3,184,845


Under current tax rules, certain currency and capital losses realized after
October 31 may be deferred and treated as occurring on the first day of the
following fiscal year. As of March 31, 2007, post-October capital losses of
$379,673 attributed to security transactions were deferred to April 1, 2007.

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109 (the "Interpretation"). This
Interpretation is effective on the last business day of the semiannual
reporting period for fiscal years beginning after December 15, 2006 and is to
be applied to open tax positions upon initial adoption. This Interpretation
prescribes a minimum recognition threshold and measurement method for the
financial statement recognition of tax positions taken or expected to be taken
in a tax return and also requires certain expanded disclosures. Management is
evaluating the application of this Interpretation to the Fund and has not at
this time quantified the impact, if any, resulting from the adoption of this
Interpretation on the Fund's financial statements.

Note 4. Fees and Compensation Paid to Affiliates

Investment Advisory Fee
Columbia, an indirect, wholly-owned subsidiary of Bank of America Corporation
("BOA"), is the investment advisor to the Fund. Columbia receives a monthly
investment advisory fee at the annual rate of 0.10% of the Fund's average daily
net assets.

Administration Fee
Columbia provides administrative services to the Fund pursuant to an
administrative services agreement. Columbia, from the administration fee it
receives from the Fund, pays all expenses of the Fund, except the fees and
expenses of the Trustees who are not interested persons, service and
distribution fees, brokerage fees and commissions, annual sub-account fees
payable with respect to shares of the Fund held by defined contribution plans,
interest on borrowings, taxes and such extraordinary, non-recurring expenses as
may arise, including litigation expenses. Columbia receives a monthly
administration fee for its services as administrator at the annual rate of
0.30% of the average daily net assets of the Fund.

Underwriting Discounts, Service and Distribution Fees
Columbia Management Distributors, Inc. (the "Distributor"), an affiliate of
Columbia and an indirect, wholly-owned subsidiary of BOA, is the principal
underwriter of the Fund. For the year ended March 31, 2007, the Distributor has
retained net underwriting discounts $5,992 on sales of the Fund's Class A
shares and net CDSC fees of $0, $5,923 and $0 on Class A, Class B and Class C
share redemptions, respectively.

18




Columbia U.S. Treasury Index Fund

March 31, 2007


The Fund has adopted a Rule 12b-1 plan (the "Plan"), which allows the payment
of a monthly service fee to the Distributor at the annual rate of 0.25% of the
average daily net assets attributable to Class A, Class B and Class C shares of
the Fund. The Plan also requires the payment of a monthly distribution fee to
the Distributor equal to 0.75% annually of the average daily net assets
attributable to Class B and Class C shares only. The Distributor has
voluntarily agreed to waive a portion of the 12b-1 fees for Class C shares of
the Fund so that these fees do not exceed 0.85% annually of the average daily
net assets attributable to Class C shares. This arrangement may be modified or
terminated by the Distributor at any time.

The CDSC and the distribution 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.

Sub-Account Services Fee
The Trust may enter into agreements with one or more entities, including
affiliates of Columbia, pursuant to which such entities agree to perform
certain sub-account and administrative functions ("Sub-Account Services") for a
fee of $21.00 per-account with respect to Class Z shares of the Fund held by
defined contribution plans. Such entities are compensated by the Fund for the
Sub-Account Services. For the year ended March 31, 2007, the Administrator
reimbursed the Fund for sub-account service fees in the amount of $13,333 for
the Fund.

Fee Waivers
Columbia has voluntarily agreed to waive fees and reimburse the Fund for
certain expenses to the extent that total expenses (exclusive of distribution
and service fees, sub account service fees, brokerage commissions, interest,
taxes and extraordinary expenses, if any) exceed the annual rate of 0.35% of
the Fund's average daily net assets. Columbia, at its discretion, may revise or
discontinue this arrangement at any time.

Fees Paid to Officers and Trustees
All officers of the Fund are employees of Columbia or its affiliates and, with
the exception of the Fund's Chief Compliance Officer, receive no compensation
from the Fund. The Board of Trustees has appointed a Chief Compliance Officer
to the Fund in accordance with federal securities regulations. The Fund, along
with other affiliated funds, pays its pro-rata share of the expenses associated
with the Chief Compliance Officer. The Fund's expenses for 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 the requirements of
the Sarbanes-Oxley Act of 2002. The fees for such services are included as part
of the administration fee.

Note 5. Portfolio Information
For the year ended March 31, 2007, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $54,715,213 and
$53,371,320 respectively, all of which were U.S. Government securities.

Note 6. Line of Credit
The Trust and other affiliated funds participate in a $350,000,000 committed
unsecured revolving line of credit and a $150,000,000 uncommitted, unsecured
line of credit, both provided by State Street. Borrowings are available for
temporary or emergency purposes.

Interest on the committed line of credit is charged to each participating fund
based on the fund's borrowings at a rate per annum equal to the Federal Funds
Rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued
and apportioned among the participating funds based on their pro-rata portion
of the unutilized committed line of credit. Interest on the uncommitted line of
credit is charged to each participating fund based on the fund's borrowings at
a variable rate per annum equal to the Federal Funds Rate plus a spread, as
determined and quoted by State Street at the time of the request for a loan. A
one-time structuring fee of $30,000 is also accrued and apportioned to each
fund participating in the uncommitted line of credit based on the average net
assets of the participating funds. In addition, if the uncommitted line of
credit is extended for an additional period, an annual administration fee of
$15,000 will be charged and apportioned among the participating fund. The
commitment fee and structuring fee are included in "Other expenses" in the
Statement of Operations.

                                                                             19




Columbia U.S. Treasury Index Fund

March 31, 2007


For the year ended March 31, 2007, the average daily loan balance outstanding
on days where borrowing existed was $1,000,000 at a weighted average interest
rate of 5.60%

Note 7. Shares of Beneficial Interest
As of March 31, 2007, one shareholder held 32.4% of the shares outstanding. The
shares were beneficially owned by participant accounts over which BOA and/or
its affiliates had either sole or joint investment discretion. Subscription and
redemption activity of these accounts may have a significant effect on the
operations of the Fund.

Note 8. Securities Lending
The Fund commenced a securities lending program in August 2006 and may lend its
securities to certain approved brokers, dealers and other financial
institutions. Each loan is collateralized by cash, in an amount at least equal
to the market value of the securities loaned plus accrued income from the
investment of collateral. The market value of the loaned securities is
determined at the close of business of the Fund and any additional required
collateral is delivered to the Fund on the next business day. The collateral
received is invested and the income generated by the investment of the
collateral, net of any fees remitted to State Street as the lending agent and
borrower rebates, is paid to the Fund. Generally, in the event of borrower
default, the Fund has the right to use the collateral to offset any losses
incurred. In the event the Fund is delayed or prevented from exercising its
right to dispose of the collateral, there may be a potential loss to the Fund.
The Fund bears the risk of loss with respect to the investment of collateral.

Note 9. Disclosure of Significant Risks and Contingencies

Legal Proceedings
On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged
into Banc of America Capital Management, LLC (now named Columbia Management
Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has
been renamed Columbia Management Distributors, Inc.) (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") on matters
relating to mutual fund trading. The SEC Order and the NYAG Settlement are
referred to collectively as the "Settlements".
Under the terms of the SEC Order, the Columbia Group 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 to reduce management fees for certain
Columbia Funds (including the former Nations Funds) and other mutual funds
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 that was developed by an independent distribution consultant
and approved by the SEC on April 6, 2007.
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 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.
On February 20, 2004, the Judicial Panel on Multidistrict Litigation
transferred these cases and cases against other mutual fund companies based on
similar allegations to the United States District Court in Maryland for
consolidated or coordinated pretrial proceedings (the ''MDL''). Subsequently,
additional related cases were transferred to the MDL. On September 29, 2004,
the plaintiffs in the MDL filed amended and consolidated complaints. One of
these amended complaints is a putative class action that includes

March 31, 2007

claims under the federal securities laws and state common law, and that names
Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America
Corporation and others as defendants. Another of the amended complaints is a
derivative action purportedly on behalf of the Columbia Funds that asserts
claims under federal securities laws and state common law.
On February 25, 2005, Columbia and other defendants filed motions to dismiss
the claims in the pending cases. On March 1, 2006, for reasons stated in the
court's memoranda dated November 3, 2005, the U.S. District Court for the
District of Maryland granted in part and denied in part the defendants' motions
to dismiss. The court dismissed all of the class action claims pending against
the Columbia Funds Trusts. As to Columbia and the Distributor, the claims under
the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the
Investment Company Act of 1940 ("ICA") and the state law claims were dismissed.
The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of
1934 and claims under Section 36(b) of the ICA were not dismissed.
On March 21, 2005, a purported class action was filed in Massachusetts state
court alleging that certain conduct, including market timing, entitled Class B
shareholders in certain Columbia funds to an exemption from contingent deferred
sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit was
removed to federal court in Massachusetts and the federal Judicial Panel
transferred the CDSC Lawsuit to the MDL.
On April 4, 2006, the plaintiffs and the Columbia defendants named in the MDL,
including the Columbia Funds, entered into a term sheet containing the
principal terms of a stipulation of settlement that would settle all
Columbia-related claims in the MDL described above, including the CDSC Lawsuit.
On April 6, 2006, the U.S. District Court for the District of Maryland stayed
all actions with respect to these Columbia-related claims. The settlement is
subject to court approval.
In 2004, the Columbia Funds' adviser and distributor and certain affiliated
entities and individuals 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.
Certain Columbia Funds were named as nominal defendants. 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 purposes. 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. On November 30, 2005, the judge dismissed all claims by
plaintiffs and entered final judgment in favor of the defendants. The
plaintiffs appealed to the United States Court of Appeals for the First Circuit
on December 30, 2005. A stipulation and settlement agreement dated January 19,
2007 was filed in the First Circuit on February 14, 2007, with a joint
stipulation of dismissal and motion for remand to obtain district court
approval of the settlement. That joint motion was granted and the appeal was
dismissed. On March 6, 2007, the case was remanded to the District Court. On
May 11, 2007, the District Court entered a preliminary approval order which
granted preliminary approval of the settlement. A final settlement hearing, at
which the District Court will determine whether the proposed settlement should
be finally approved and the action dismissed on the merits with prejudice, is
scheduled for September 18, 2007. The terms of the settlement, if finally
approved, will require payments by the funds' adviser and/or its affiliates,
including payment of plaintiffs' attorneys' fees and notice to class members.
In the event that the settlement is not finally approved, the plaintiffs may
elect to go forward with their appeal and no opinion is expressed regarding the
likely outcome or financial impact of such an appeal on any fund.

                                                                             21




Report Of Independent Registered Public Accounting Firm


To the Trustees of Columbia Funds Series Trust I and the Shareholders of
Columbia U.S. Treasury Index Fund

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Columbia U.S. Treasury Index Fund
(the "Fund") (a series of Columbia Funds Series Trust I) at March 31, 2007, and
the results of its operations, the changes in its net assets and the financial
highlights for the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management. Our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at March 31, 2007 by correspondence with the
custodian, provide a reasonable basis for our opinion.

Board Consideration and Approval of
Investment Advisory Agreements

The Advisory Fees and Expenses Committee of the Board of Trustees meets one or
more times annually to review the advisory agreements (collectively, the
"Agreements") of the funds for which the Trustees serve as trustees (each a
"fund") and determine whether to recommend that the full Board approve the
continuation of the Agreements for an additional one-year period. After the
Committee has made its recommendation, the full Board, including the
Independent Trustees, determines whether to approve the continuation of the
Agreements. In addition, the Board, including the Independent Trustees,
considers matters bearing on the Agreements at most of its other meetings
throughout the year and meets regularly with the heads of each investment area
within Columbia. Through the Board's Investment Oversight Committees, Trustees
also meet with selected fund portfolio managers at various times throughout the
year.

The Trustees receive and review all materials that they, their legal counsel or
Columbia, the funds' investment adviser, believe to be reasonably necessary for
the Trustees to evaluate the Agreements and determine whether to approve the
continuation of the Agreements. Those materials generally include, among other
items, (i) information on the investment performance of each fund relative to
the performance of peer groups of mutual funds and the fund's performance
benchmarks, (ii) information on each fund's advisory fees and other expenses,
including information comparing the fund's expenses to those of peer groups of
mutual funds and information about any applicable expense caps and fee
"breakpoints," (iii) information about the profitability of the Agreements to
Columbia, including potential "fall-out" or ancillary benefits that Columbia
and its affiliates may receive as a result of their relationships with the
funds and (iv) information obtained through Columbia's response to a
questionnaire prepared at the request of the Trustees by counsel to the funds
and independent legal counsel to the Independent Trustees. The Trustees also
consider other information such as (v) Columbia's financial results and
financial condition, (vi) each fund's investment objective and strategies and
the size, education and experience of Columbia's investment staffs and their
use of technology, external research and trading cost measurement tools, (vii)
the allocation of the funds' brokerage, if any, and the use of "soft"
commission dollars to pay for research products and services, (viii) Columbia's
resources devoted to, and its record of compliance with, the funds' investment
policies and restrictions, policies on personal securities transactions and
other compliance policies, (ix) Columbia's response to various legal and
regulatory proceedings since 2003 and (x) the economic outlook generally and
for the mutual fund industry in particular. In addition, the Advisory Fees and
Expenses Committee confers with the funds' independent fee consultant and
reviews materials relating to the funds' relationships with Columbia provided
by the independent fee consultant. Throughout the process, the Trustees have
the opportunity to ask questions of and request additional materials from
Columbia and to consult with independent legal counsel to the Independent
Trustees and the independent fee consultant.

The Board of Trustees most recently approved the continuation of the Agreements
at its October, 2006 meeting, following meetings of the Advisory Fees and
Expenses Committee held in August, September and October, 2006. In considering
whether to approve the continuation of the Agreements, the Trustees, including
the Independent Trustees, did not identify any single factor as determinative,
and each weighed various factors as he or she deemed appropriate. The Trustees
considered the following matters in connection with their approval of the
continuation of the Agreements:

The nature, extent and quality of the services provided to the funds under the
Agreements. The Trustees considered the nature, extent and quality of the
services provided by Columbia and its affiliates to the funds and the resources
dedicated to the funds by Columbia and its affiliates. Among other things, the
Trustees considered (i) Columbia's ability (including its personnel and other
resources, compensation programs for personnel involved in fund management,
reputation and other attributes) to attract and retain highly qualified
research, advisory and supervisory investment professionals; (ii) the portfolio
management services provided by those investment professionals; and (iii) the
trade execution services provided on behalf of the funds. For each fund, the
Trustees also considered the benefits to shareholders of investing in a mutual
fund that is part of a family of funds offering exposure to a variety of asset
classes and investment disciplines and providing a variety of fund and
shareholder services. After reviewing those and related factors, the Trustees
concluded, within the context of their overall conclusions regarding each of
the Agreements, that the nature, extent and quality of services provided
supported the continuation of the Agreements.

28







Investment performance of the funds and Columbia. The Trustees reviewed
information about the performance of each fund over various time periods,
including information prepared by an independent third party that compared the
performance of each fund to the performance of peer groups of mutual funds and
performance benchmarks. The Trustees also reviewed a description of the third
party's methodology for identifying each fund's peer group for purposes of
performance and expense comparisons. The Trustees also considered additional
information that the Advisory Fees and Expenses Committee requested from
Columbia relating to funds that presented relatively weaker performance and/or
relatively higher expenses.

In the case of each fund whose performance lagged that of a relevant peer group
for certain (although not necessarily all) periods, the Trustees concluded that
other factors relevant to performance were sufficient, in light of other
considerations, to warrant continuation of the fund's Agreements. Those factors
varied from fund to fund, but included one or more of the following: (i) that
the fund's performance, although lagging in certain recent periods, was
stronger over the longer term; (ii) that the underperformance was attributable,
to a significant extent, to investment decisions that were reasonable and
consistent with the fund's investment strategy and policies and that the fund
was performing as expected, given these investment decisions, market conditions
and the fund's investment strategy; (iii) that the fund's performance was
competitive when compared to other relevant performance benchmarks or peer
groups; (iv) that Columbia had taken or was taking steps designed to help
improve the fund's investment performance, including, but not limited to,
replacing portfolio managers or modifying investment strategies; and (v) that
the fund was proposed to be reorganized into another fund, and that such
reorganization would result in a reduction in fund expenses.

The Trustees also considered Columbia's performance and reputation generally,
the funds' performance as a fund family generally, and Columbia's historical
responsiveness to Trustee concerns about performance and Columbia's willingness
to take steps intended to improve performance.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
performance of each fund and Columbia was sufficient, in light of other
considerations, to warrant the continuation of the Agreement(s) pertaining to
that fund.

The costs of the services provided and profits realized by Columbia and its
affiliates from their relationships with the funds. The Trustees considered the
fees charged to the funds for advisory services as well as the total expense
levels of the funds. That information included comparisons (provided by
management and by an independent third party) of each fund's advisory fees and
total expense levels to those of the fund's peer groups and information about
the advisory fees charged by Columbia to comparable institutional accounts. In
considering the fees charged to those accounts, the Trustees took into account,
among other things, management's representations about the differences between
managing mutual funds as compared to other types of accounts, including
differences in the services provided, differences in the risk profile of such
business for Columbia, and the additional resources required to manage mutual
funds effectively. In evaluating each fund's advisory fees, the Trustees also
took into account the demands, complexity and quality of the investment
management of the fund. The Trustees considered existing advisory fee
breakpoints, and Columbia's use of advisory fee waivers and expense caps, which
benefited a number of the funds. The Trustees also noted management's stated
justification for the fees charged to the funds, which included information
about the investment performance of the funds and the services provided to the
funds. The Trustees also considered the compensation directly or indirectly
received by Columbia and its affiliates from their relationships with the
funds. The Trustees reviewed information provided by management as to the
profitability to Columbia and its affiliates of their relationships with each
fund, and information about the allocation of expenses used to calculate
profitability. When reviewing profitability, the Trustees also considered court
cases in which adviser profitability was an issue in whole or in part, the
performance of the relevant funds, the expense level of each fund, and whether
Columbia had implemented breakpoints and/or expense caps with respect to the
fund.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
advisory fees charged to each fund, and the related profitability to Columbia
and its affiliates of their relationships with the fund, supported the
continuation of the Agreement(s) pertaining to that fund.

                                                                             29







Economies of Scale. The Trustees considered the existence of any economies of
scale in the provision by Columbia of services to each fund, to groups of
related funds, and to Columbia's investment advisory clients as a whole and
whether those economies were shared with the funds through breakpoints in the
investment advisory fees or other means, such as expense waivers/reductions and
additional investments by Columbia in investment, trading and compliance
resources. The Trustees noted that many of the funds benefited from
breakpoints, expense caps, or both. In considering those issues, the Trustees
also took note of the costs of the services provided (both on an absolute and a
relative basis) and the profitability to Columbia and its affiliates of their
relationships with the funds, as discussed above.

After reviewing those and related factors, the Trustees concluded, within the
context of their overall conclusions regarding each of the Agreements, that the
extent to which economies of scale were shared with the funds supported the
continuation of the Agreements.

Other Factors. The Trustees also considered other factors, which included but
were not limited to the following:

.. the extent to which each fund had operated in accordance with its investment
  objective and investment restrictions, the nature and scope of the compliance
  programs of the funds and Columbia and the compliance-related resources that
  Columbia and its affiliates were providing to the funds;

.. the nature, quality, cost and extent of administrative and shareholder
  services performed by Columbia and its affiliates, both under the Agreements
  and under separate agreements for the provision of transfer agency and
  administrative services;

.. so-called "fall-out benefits" to Columbia and its affiliates, such as the
  engagement of its affiliates to provide distribution, brokerage and transfer
  agency services to the funds, and the benefits of research made available to
  Columbia by reason of brokerage commissions generated by the funds'
  securities transactions, as well as possible conflicts of interest associated
  with those fall-out and other benefits, and the reporting, disclosure and
  other processes in place to disclose and monitor those possible conflicts of
  interest; and

.. the draft report provided by the funds' independent fee consultant, which
  included information about and analysis of the funds' fees, expenses and
  performance.

Based on their evaluation of all factors that they deemed to be material,
including those factors described above, and assisted by the advice of
independent counsel and the independent fee consultant, the Trustees, including
the Independent Trustees, approved the continuance of each of the Agreements
through October 31, 2007.

Summary of Management Fee Evaluation by
Independent Fee Consultant

Prepared Pursuant to the February 9, 2005 Assurance of Discontinuance between
the Office of Attorney General of New York State and Columbia Management
Advisors, Inc. and Columbia Funds Distributor, Inc. October 11, 2006

  I. Overview

Columbia Management Advisors, LLC ("CMA") and Columbia Funds Distributors,
Inc./1/ ("CFD") agreed on February 9, 2005 to the New York Attorney General's
Assurance of Discontinuance ("AOD"). Among other things, the AOD stipulates
that CMA may manage or advise a Columbia Fund ("Fund" and together with all
such funds or a group of such funds as the "Funds") only if the Independent
Members of the Fund's Board of Trustees (such Independent Members of the Fund's
Board together with the other members of the Fund's Board, referred to as the
"Trustees") appoint a Senior Officer or retain an Independent Fee Consultant
("IFC") who is to manage the process by which proposed management fees are
negotiated. The AOD further stipulates that the Senior Officer or IFC is to
prepare a written annual evaluation of the fee negotiation process.

On September 14, 2006, the Independent Members of the Funds' Boards retained me
as IFC for the Funds. In this capacity, I have prepared the second annual
written evaluation of the fee negotiation process. I am successor to the first
IFC, Erik Sirri, who prepared the annual evaluation in 2005 and who contributed
to the second annual written evaluation until his resignation as IFC in August
2006 to become Director of the Division of Market Regulation at the U.S.
Securities and Exchange Commission./2/

A. Role of the Independent Fee Consultant
The AOD charges the IFC with "managing the process by which proposed management
fees...to be charged the Columbia Fund are negotiated so that they are
negotiated in a manner which is at arms' length and reasonable and consistent
with this Assurance of Discontinuance." In this role, the IFC does not replace
the Trustees in negotiating management fees with CMA, and the IFC does not
substitute his or her judgment for that of the Trustees about the
reasonableness of proposed fees. As the AOD states, CMA "may manage or advise a
Columbia Fund only if the reasonableness of the proposed management fees is
determined by the Board of Trustees...using...an annual independent written
evaluation prepared by or under the direction of...the Independent Fee
Consultant."

B. Elements Involved in Managing the Fee Negotiation Process
Managing the fee negotiation process has three elements. One involves reviewing
the information provided by CMG to the Trustees for evaluating the proposed
management fees and augmenting that information, as necessary, with additional
information from CMG or other sources and with further analyses of the
information and data. The second element involves reviewing the information and
analysis relative to at least the following six factors set forth in the AOD:

1.The nature and quality of CMA's services, including the Fund's performance;

2.Management fees (including any components thereof) charged by other mutual
  fund companies for like services;

3.Possible economies of scale as the Fund grows larger;

4.Management fees (including any components thereof) charged to institutional
  and other clients of CMA for like services;

5.Costs to CMA and its affiliates of supplying services pursuant to the
  management fee agreements, excluding any intra-corporate profit; and

6.Profit margins of CMA and its affiliates from supplying such services.

1CMA and CFD are subsidiaries of Columbia Management Group, Inc. ("CMG"), which
 also is the parent of Columbia Management Services, Inc. ("CFS"), the Funds'
 transfer agent. Before the date of this report, CMA merged into an affiliated
 entity, Banc of America Capital Management, LLC, which was renamed Columbia
 Management Advisors, LLC and which carries on the business of CMA. CFD also
 has been renamed Columbia Management Distributors, Inc.
2I am an independent economic consultant. From August 2005 until August 2006, I
 provided support to Mr. Sirri as an independent consultant. From 1994 to 2004,
 I was Chief Economist at the Investment Company Institute. Earlier, I was
 Section Chief and Assistant Director at the Federal Reserve Board and
 Professor of Economics at Oklahoma State University. I have no material
 relationship with Bank of America or CMG, aside from serving as IFC, and I am
 aware of no material relationship with any of their affiliates. To assist me
 with the report, I engaged NERA Economic Consulting, an independent consulting
 firm that has had extensive experience in the mutual fund industry. I also
 have retained Willkie Farr & Gallagher LLP as counsel to advise me in
 connection with the report.

                                                                             31







The final element involves providing the Trustees with a written evaluation of
the above factors as they relate to the fee negotiation process.

C. Organization of the Annual Evaluation
The 2006 annual evaluation focuses on the six factors and contains a section
for each factor except that CMA's costs and profits from managing the Funds
have been combined into a single section. In each section, the discussion of
the factor considers and analyzes the available data and other information as
they bear upon the fee negotiation process. If appropriate, the discussion in
the section may point out certain aspects of the proposed fees that may warrant
particular attention from the Trustees. The discussion also may suggest other
data, information, and approaches that the Trustees might consider
incorporating into the fee negotiation process in future years.

In addition to a discussion of the six factors, the report reviews the status
of recommendations made in the 2005 IFC evaluation. The 2006 report also
summarizes the findings with regard to the six factors and contains a summary
of recommendations for possible enhancements to the process.

  II. Status of 2005 Recommendations

The 2005 IFC evaluation contains recommendations aimed at enhancing the
evaluation of proposed management fees by Trustees. The section summarizes
those recommendations and includes my assessment of the response to the
recommendations.

1.  Recommendation: Trustees should consider requesting more analytical work
    from CMG in the preparation of future 15(c) materials.

    Status: CMG has provided additional analyses to the Trustees on economies
    of scale, a comparative analysis of institutional and retail management
    fees, management fee breakpoints, risk-adjusted performance, fee waivers
    and expense reimbursements, and CMG's costs and profitability.

2.  Recommendation: Trustees may wish to consider whether CMG should continue
    expanding the use of Morningstar or other third party data to supplement
    CMG's fee and performance analysis that is now based primarily on Lipper
    reports.

    Status: CMG has used data from Morningstar Inc. to compare with data from
    Lipper Inc. ("Lipper") in performing the Trustees' screening procedures.

3.  Recommendation: Trustees should consider whether...the fund-by-fund
    screen...should place comparable emphasis on both basis point and quintile
    information in their evaluation of the funds...Also, the Trustees should
    consider incorporating sequences of one year performance into a
    fund-by-fund screen.

    Status: CMG has not provided Trustees with results of the screening process
    using percentiles. CMG has provided Trustees with information on the
    changes in performance and expenses between 2005 and 2006 and data on
    one-year returns.

4.  Recommendation: Given the volatility of fund performance, the Trustees may
    want to consider whether a better method exists than th[e] fee waiver
    process to deal with fund underperformance.

    Status: It is my understanding that the Trustees have determined to address
    fund underperformance not only through fee waivers and expense caps but
    also through discussions with CMG regarding the sources of
    underperformance. CMG has provided Trustees with an analysis of the
    relationship between breakpoints, expense reimbursements, and fee waivers.

5.  Recommendation: [Seventy-one] percent of funds [have] yet to reach their
    first management fee breakpoint... Trustees may wish to consider whether
    the results of my ongoing economies-of-scale work affects the underlying
    economic assumptions reflected in the existing breakpoint schedules.

    Status: CMG has prepared a memo for the Trustees discussing its views on
    the nature and sharing of potential economies of scale. The memo discuses
    CMG's view that economies of scale arise at the complex level rather than
    the fund level. The memo also describes steps, including the introduction
    of breakpoints, taken to share economies of scale with shareholders. CMG's
    analysis, however, does not discuss specific sources of economies of scale
    and does not link breakpoints to economies of scale that might be realized
    as the Funds' assets increase.

32







6.  Recommendation: Trustees should continue working with management to address
    issues of funds that demonstrate consistent or significant underperformance
    even if the fee levels for the funds are low.

    Status: Trustees monitor performance on an ongoing basis.

  III. Findings

A. General
1.  Based upon my examination of the available information and the six factors,
    I conclude that the Trustees have the relevant information necessary to
    evaluate the reasonableness of the proposed management fees for the Funds.
    CMG has provided the Trustees with relevant materials on the six factors
    through the 15(c) contract renewal process and in materials prepared for
    review at Board and Committee meetings.

2.  In my view, the process by which the proposed management fees of the Funds
    have been negotiated in 2006 thus far has been, to the extent practicable,
    at arms' length and reasonable and consistent with the AOD.

B. Nature and Quality of Services, Including Performance
3.  The performance of the Funds has been relatively strong, especially that of
    fixed-income Funds. For each of the 1-, 3-, 5- and 10-year performance
    periods, over 60 percent of the funds have ranked in the top three
    performance quintiles.

4.  The performance of the equity Funds overall, though less concentrated in
    the top two quintiles than the fixed income Funds, improved in 2006
    relative to that in 2005. The fixed-income funds maintained the relatively
    high performance level of 2005 in 2006.

5.  The Funds' overall performance adjusted for risk was significantly stronger
    than performance unadjusted for risk. Domestic and international equity
    funds, in particular, moved to higher relative performance rankings after
    adjusting for risk.

6.  The procedure used to construct the performance universe in which each
    Fund's performance is ranked relative to comparable funds may bias a Fund's
    ranking upward within that universe. The bias occurs because the
    performance ranking procedure includes all share classes of multi-class
    funds in the universe and because the procedure ranks either no-load or A
    share classes of the Funds. No-load and A share classes generally have
    lower total expenses than B and C shares (owing to B and C shares having
    higher distribution/service fees) and thus, given all else, would
    outperform many of B and C share classes included in the universe. A
    preliminary analysis that adjusts for the bias results in a downward
    movement in the relative performance for the Funds but does not change the
    general finding that the Funds' performance has been strong relative to
    comparable funds.

C. Management Fees Charged by Other Mutual Fund Companies
7.  The Funds' management fees and total expenses are generally low relative to
    those of their peers. At least 56 percent of the Funds are in the first or
    second quintiles with the lowest fees and expenses and nearly three fourths
    or more in the first three quintiles. Equity Funds are more highly
    concentrated in the first three quintiles than fixed-income Funds.

8.  The fee and expense rankings as whole are similar to those in 2005 in that
    the majority of funds are ranked in the top quintiles. Nonetheless, a
    number of individual funds experienced a change in ranking between 2005 and
    2006. This fund-level instability may reflect sensitivity of rankings to
    the composition of the comparison groups, as the membership of the peer
    groups typically changed substantially between the two years.

9.  The Liberty Money Market Fund VS appears to have a higher management fee
    structure than that of other Columbia money market funds of comparable
    asset size.

                                                                             33







D. Trustees' Fee and Performance Evaluation Process
10. The Trustees' evaluation process identified 21 funds in 2006 for further
    review based upon their relative performance or expenses. Seventeen of
    these funds had been subject to review in 2004 or 2005.

E. Potential Economies of Scale
11. CMG has prepared a memo for the Trustees containing its views on the
    sources and sharing of potential economies of scale. CMG views economies of
    scale as arising at the complex level and would regard estimates of scale
    economies for individual funds as unreliable. CMG has not, however,
    identified specific sources of economies of scale nor has it provided any
    estimates of the magnitude of any economies of scale. In the memo, CMG also
    describes measures taken by the Trustees and CMG that seek to share any
    potential economies of scale through breakpoints in management fee
    schedules, expense reimbursements, fee waivers, enhanced shareholder
    services, fund mergers, and operational consolidation. These measures,
    although of significant benefit to shareholders, have not been directly
    linked in the memo to the existence, sources, and magnitude of economies of
    scale.

F. Management Fees Charged to Institutional Clients
12. CMG has provided Trustees with comparisons of mutual fund management fees
    and institutional fees based upon standardized fee schedules and upon
    actual fees. Based upon the information, institutional fees are generally
    lower than the Funds' management fees. This pattern is consistent with the
    economics of the two financial products. Data are not available, however,
    on actual institutional fees at other money managers. Thus, it is not
    possible to determine the extent to which differences between the Funds'
    management fees and institutional fees are consistent with those seen
    generally in the marketplace.

G. Revenues, Expenses, and Profits
13. The financial statements and the methodology underlying their construction
    generally form a sufficient basis for Trustees to evaluate the expenses and
    profitability of the Funds.

  IV. Recommendations

A. Performance
1.  Trustees may wish to consider incorporating risk adjusted measures in their
    evaluation of performance. CMG has begun to prepare reports for the
    Trustees with risk adjustments, which could form the basis for formally
    including the measures in the 15(c) materials. To this end, Trustees may
    wish to have CMG prepare documents explaining risk adjustments and
    describing their advantages and disadvantages.

2.  Trustees may wish to consider having CMG evaluate the sensitivity of
    performance rankings to the design of the universe. The preliminary
    analysis contained in the evaluation suggests that the method employed by
    Lipper, the source of performance rankings used by the Trustees, may bias
    performance rankings upward.

B. Economies of Scale
3.  Trustees may wish to consider having CMG extend its analysis of economies
    of scale by examining the sources of such economies, if any. Identification
    of the sources may enable the Trustees and CMG to gauge their magnitude. It
    also may enable the Trustees and CMG to build upon past work on
    standardized fee schedules so that the schedules themselves are consistent
    with any economies of scale and their sources. Finally, an extension of the
    analysis may enable the Trustees and CMG to develop a framework that
    coordinates the use of fee waivers and expense caps with the standard fee
    schedules and with any economies of scale and their sources.

C. Institutional Fees
4.  Trustees may wish to consider encouraging CMG to build further upon its
    expanded analysis of institutional fees by refining the matching of
    institutional accounts with mutual funds, by dating the establishment of
    each institutional account, and by incorporating other accounts, such as
    subadvisory relationships, trusts, offshore funds, and separately managed
    accounts into the analysis.

34







D. Profitability
5.  Trustees may wish to consider requesting that CMG expand the reporting of
    revenues and expenses to include more line-item detail for management and
    administration, transfer agency, fund accounting, and distribution.

6.  Trustees may wish to consider requesting that CMG provide a statement of
    its operations in the 15(c) materials.

7.  Trustees may wish to consider the treatment of the revenue sharing with the
    Private Bank of Bank of America in their review of CMG's profitability.

Respectfully submitted,
John D. Rea

                                                                             35




Appendix


Sources of Information Used in the Evaluation

The following list generally describes the sources and types of information
that were used in preparing this report.

1.  Performance, management fees, and expense ratios for the Funds and
    comparable funds from other fund complexes from Lipper and CMG. The sources
    of this information were CMG and Lipper;

2.  CMG's expenses and profitability obtained directly from CMG;

3.  Information on CMG's organizational structure;

4.  Profitability of publicly traded asset managers from Lipper;

5.  Interviews with CMG staff, including members of senior management, legal
    staff, heads of affiliates, portfolio managers, and financial personnel;

6.  Documents prepared by CMG for Section 15(c) contract renewals in 2005 and
    2006;

7.  Academic research papers, industry publications, professional materials on
    mutual fund operations and profitability, and SEC releases and studies of
    mutual fund expenses

8.  Interviews with and documents prepared by Ernst & Young LLP in its review
    of the Private Bank Revenue Sharing Agreement;

9.  Discussions with Trustees and attendance at Board and committee meetings
    during which matters pertaining to the evaluation were considered.

In addition, I engaged NERA Economic Consulting ("NERA") to assist me in data
management and analysis. NERA has extensive experience in the mutual fund
industry that provides unique insights and special knowledge pertaining to my
independent analysis of fees, performance, and profitability. I have also
retained attorneys in the Washington, D.C. office of Willkie Farr & Gallagher
LLP as outside counsel to advise me in connection with my evaluation.

Finally, meetings and discussions with CMG staff were informative. My
participation in Board and committee meetings in which Trustees and CMG
management discussed issues relating to management contracts were of great
benefit to the preparation of the evaluation.

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee is required to pre-approve the engagement of
the registrant's independent accountants to provide audit and non-audit
services to the registrant and non-audit services to its investment adviser
(not including any sub-adviser whose role is primarily portfolio management and
is subcontracted with or overseen by another investment adviser) or any entity
controlling, controlled by or under common control with such investment adviser
that provides ongoing services to the registrant ("Adviser Affiliates"), if the
engagement relates directly to the operations and financial reporting of the
registrant.

   The Audit Committee has adopted a Policy for Engagement of Independent
Accountants for Audit and Non-Audit Services ("Policy"). The Policy sets forth
the understanding of the Audit Committee regarding the engagement of the
registrant's independent accountants to provide (i) audit and permissible
audit-related, tax and other services to the registrant (collectively "Fund
Services"); (ii) non-audit services to the registrant's investment adviser (not
including any sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by another investment adviser) and Adviser
Affiliates, if the engagement relates directly to the operations or financial
reporting of a Fund (collectively "Fund-related Adviser Services"); and (iii)



certain other audit and non-audit services to the registrant's investment
adviser (not including any sub-adviser whose role is primarily portfolio
management and is subcontracted with or overseen by another investment adviser)
and Adviser Affiliates. Unless a type of service receives general pre-approval
under the Policy, it requires specific pre-approval by the Audit Committee if
it is to be provided by the independent accountants. Pre-approval of non-audit
services to the registrant, the registrant's investment adviser (not including
any sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by another investment adviser) and Adviser
Affiliates may be waived provided that the "de minimis" requirements set forth
under paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are met.

   Under the Policy, the Audit Committee may delegate pre-approval authority to
any pre-designated member or members who are Independent Trustees/Directors.
The member(s) to whom such authority is delegated must report, for
informational purposes only, any pre-approval decisions to the Audit Committee
at its next regular meeting. The Audit Committee's responsibilities with
respect to the pre-approval of services performed by the independent
accountants may not be delegated to management.

   The Policy requires the Fund Treasurer and/or Director of Board
Administration to submit to the Audit Committee, on an annual basis, a schedule
of the types of services that are subject to general pre-approval. The
schedule(s) provide a description of each type of service that is subject to
general pre-approval and, where possible, will provide estimated fee caps for
each instance of providing each service. The Audit Committees will review and
approve the types of services and review the projected fees for the next fiscal
year and may add to, or subtract from, the list of general pre-approved
services from time to time based on subsequent determinations. That approval
acknowledges that the Audit Committee is in agreement with the specific types
of services that the independent accountants will be permitted to perform.

The Fund Treasurer and/or Director of Board Administration shall report to the
Audit Committee at each of its regular meetings regarding all Fund Services or
Fund-related Adviser Services initiated since the last such report was
rendered, including a general description of the services, actual billed and
projected fees, and the means by which such Fund Services or Fund-related
Adviser Services were pre-approved by the Audit Committee.

                                     *****

(e)(2) The percentage of services described in paragraphs (b) through (d) of
this Item approved pursuant to the "de minimis" exception under paragraph
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X during both fiscal years ended
March 31, 2007 and March 31, 2006 was zero.

(f)Not applicable.



(g) The aggregate non-audit fees billed by the registrant's accountant for
services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the registrant for
the fiscal years ended March 31, 2007 and March 31, 2006 are approximately as
follows:

                          2007                 2006
                        $892,900             $411,000

(h) The registrant's Audit Committee of the Board of Directors has considered
whether the provision of non-audit services that were rendered to the
registrant's adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X, is compatible with maintaining the principal
accountant's independence.

Not applicable.

Item 6. Schedule of Investments

issuers" (as set forth in 17 CFR 210.12-12) is included in Item 1 of this Form

Item 10. Submission of Matters to a Vote of Security Holders.

shareholders may recommend nominees to the registrant's board of directors,
since those procedures were last disclosed in response to requirements of
Item 7(d)(2)(ii)(G) of Schedule 14A or this Item.

Item 11. Controls and Procedures.

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

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