                           AN OVERVIEW OF THE MARKETS
       -----------------------------------------------------------------
 
A LOOK BACK AT 1998
 
1998 was an extraordinary year in many respects, most notably in the divergence
of returns among different types of investments. Volatility and uncertainty
characterized the markets, especially in the latter half of the year. Stock
investors took a wild ride as the S&P 500 rose 17.71% in the first half, then
fell 14.46% in the month of August, only to recover the year's gains and finish
up 28.58% for the full year. This marked an unprecedented fourth consecutive
year of greater than 20% returns for U.S. equity markets.
 
Although market breadth improved in the fourth quarter, the smaller cap Russell
2000 Index ended the year with a loss of 2.55%. International markets generally
performed poorly with the exception of Europe, which rose in anticipation of the
benefits of the impending European Monetary Union.
 
The bond market proved no exception to this pattern of divergent returns.
Investors' flight to quality pushed yields on 30-year U.S. Treasuries to their
lowest level in 30 years. However, yields on corporate, municipal and
mortgage-backed debt barely budged. The difference between rates on bonds issued
by the Treasury and those issued by corporations or municipalities remains at
historically high levels.

      * 10-Year A-rated Industrial Bonds versus 10-Year Treasury Bonds: the
        higher the plot points, the greater the differences in yields.
 
In order to calm financial markets and head off the effects of a slower world
economy on the U.S., the Federal Reserve lowered short-term interest rates by a
total of .75% in three steps during late 1998, leading the markets to stage a
spectacular recovery. Technology and Internet stocks, pharmaceutical companies,
consumer retailers and communications names were among the best performing
sectors in 1998, while commodity, real estate, oils and basic industry stocks
lagged for the year.
 
MARKET OUTLOOK
 
The outlook for the U.S. economy seems to be more dependent than ever on
developments overseas, and conditions in many regions around the world are a
cause for concern. While it seems clear that world growth is slowing, it is
still difficult to judge how this will affect the domestic economy. It appears
likely that there will be continued pressure on U.S. corporate profits stemming
from overseas activity in 1999.
 
We expect U.S. economic growth to slow from the rapid pace of previous years.
However, after the concerted efforts of the Federal Reserve and other central
banks worldwide to reduce rates, we do not anticipate a recession. These easing
actions have steadied financial markets so that share prices have recovered,
credit spreads have stabilized and new issue activity has resumed.
 
Buoyed by low interest rates, consumer spending has grown faster than income
recently, generating a negative savings rate. Such strong growth in demand seems
unsustainable and consumers may be quick to cut back if their expectations are
deflated. Given these concerns, Wall Street earnings estimates for 1999 seem
optimistic. The present benign inflation environment, however, leaves the Fed
ample room to adjust rates down to reassure investors and refuel consumption.

INVESTMENT STRATEGY
 
Throughout 1998, a narrow universe of growth stocks saw strong price gains,
while the broader market lagged, due to ongoing concerns about profit growth.
For example, 10 companies in the S&P 500 Index accounted for 43% of its gain.
Expectations for moderating growth in the U.S. and around the world lead us to
emphasize companies with strong records of delivering solid earnings gains in a
more difficult environment. We expect that divergence in earnings and profit
growth prospects among various sectors could lead to a continuing gap between
the best and worst performing groups over the coming months.
 
Columbia's focus remains on stocks we expect to be favorably influenced by such
investment themes as "Aging of America" and "Technology Age." While we believe
the long-term trends underlying the themes remain in place, we are taking a more
selective investment approach to groups within the themes. To this end, we are
concentrating on industries we expect to benefit from growth in secular
spending, which can continue to expand even in a downturn. Therefore, the Funds
are positioned with strong weightings in technology, communications and
pharmaceutical stocks.
 
Given our expectations for slower growth, we expect interest rates to remain
stable or trend lower. It seems unlikely that the Fed will take action to raise
or lower its key rate in the near term until conditions in the U.S. and overseas
become clearer. Inflation seems to be under control, and the U.S. budget surplus
continues to reduce the government's demand for new funds. In this environment,
both nominal and real yields (real yields are interest rates minus inflation) on
bonds look particularly attractive.
 
So that you may evaluate how the Columbia Funds performed given this economic
and financial market backdrop, the following pages contain discussions of the
Funds' investment activity during 1998, along with graphs illustrating the
growth of $10,000 over various time periods. Each Fund compares its performance
to a relevant benchmark. Unlike the Funds, however, these benchmark indices are
not actively managed and have no operating expenses, portfolio transaction costs
or cash flows.
 
Thank you for your investment in Columbia Funds. We appreciate your confidence
and look forward to serving your investment needs in the years to come.

                        -- COLUMBIA COMMON STOCK FUND --
                        --------------------------------
 
In a volatile year for the stock market, Columbia Common Stock Fund returned
26.28% for the 12 months through December 31, 1998. Much of the Fund's
performance can be attributed to its gain of 23.30% in a very strong fourth
quarter.
 
Throughout the year, the Fund benefited from a focus on larger capitalization
names that offered higher than average earnings potential. We bypassed cyclical
issues (stocks that rise quickly when the economy is on the upswing and fall
when the economy turns down) and trimmed holdings in REITs and electric and gas
utilities. Our continued focus on retail and domestic consumer stocks benefited
the portfolio in the fourth quarter, as a series of three Federal Reserve Board
short-term interest rate cuts from September 29 to November 17 renewed consumer
confidence.

An emphasis on certain investment themes also played a large role in stock
selection, including "The Aging of America," which hinges on opportunities
resulting from the aging U.S. population, "Technology Age," which focuses on the
increased creation, distribution and manipulation of information and
"Value-Added Consolidators," a study of companies that can accelerate earnings
growth through synergistic acquisitions. We expect to continue emphasizing "The
Aging of America" and "Technology Age" through 1999.

Columbia Growth Fund gained 30.34% for the year ended December 31, 1998,
outperforming the S&P 500, which returned 28.58% for the same period. In a
volatile year for the stock market, the Fund maintained its focus on stocks with
dependable earnings growth. Throughout the year, investment themes also shaped
stock selection, as we targeted issues poised to profit from the aging of
America and technological advances around the world. This led to an emphasis in
health care and segments of technology and financial stocks.

As of December 31, 1998
 
With consumer spending and economic growth healthy in the first quarter of the
year, the Fund benefited from increased exposure to domestic and consumer
issues. By the third quarter, however, fears escalated that consumer spending
would wane as individuals saw their wealth decrease with the sharp decline in
stock prices. Concerns about a slowdown in spending depressed the Fund's
consumer-oriented holdings, such as retail, radio broadcasting and cruise lines.
We anticipated the Federal Reserve Board would adopt more stimulative policies,
so we maintained and then increased our exposure to these consumer issues.
 
Responding to fears of an economic slowdown, the Fed lowered rates three times
between September 29 and November 17. This, combined with news of fiscal policy
changes in Brazil and Japan, rekindled consumer and investor confidence. In the
fourth quarter, the Fund's consumer issues advanced sharply, and we further
increased exposure to this sector, while purchasing more technology stocks and
other higher growth issues. Much of the Fund's one-year return can be attributed
to its 25.59% gain in the fourth quarter.

                    ---------------------------------------
 
Columbia International Stock Fund returned 12.83% for the 12 months ended
December 31, 1998. Throughout the year, positions in such growth areas as
telecommunications and technology benefited perfor-mance, and we continue to
favor them, along with pharmaceuticals.
 
Despite a strong start, international markets suffered throughout the year, due
to the continuing Asian currency crisis and a stalled Japanese economy.
 
Europe, however, proved to be a bright spot. As European nations geared up to
join the European Monetary Union (EMU), the entire region benefited from low
interest rates and disciplined fiscal policies.

During the first two quarters, the Fund's emphasis on Japanese exporters hurt
performance. This was offset somewhat as the Fund began to take greater
advantage of favorable investment opportunities in Europe, significantly
increasing its exposure to the United Kingdom, France, Germany and Spain.
 
Despite healthy economic activity in the region, European stock  markets were
affected by world turmoil, as several markets posted declines in the third
quarter. The continued troubles in Southeast Asia, stagnation/deflation in Japan
and news of troubles in Russia caused investors around the world to shun risk.
Latin American countries, and Brazil in particular, felt pressure to devalue
currencies.
 
Sentiment improved in the fourth quarter when Brazil implemented a fiscal reform
program and the International Monetary Fund agreed to provide a $41 billion
assistance package. While a low exposure to Japan was appropriate for much of
the year, the Fund increased its exposure as the yen strengthened against the
dollar in October. Although we had reduced our position in financial stocks at
the end of the third quarter, the financial stocks we retained in the portfolio
rebounded strongly when the markets recovered.

Looking forward, it is clear that world growth rates are slowing. We will
continue to favor European markets we believe still offer considerable
opportunity. Japan could surprise the markets with new reform initiatives.
However, with consensus opinion calling for continued recession, the outlook in
Japan remains uncertain.

The Special Fund returned 16.64% for the 12 months ended December 31, 1998.
Small and mid-cap stocks struggled throughout the year, as risk-averse investors
focused on a narrow group of large cap stocks. However, smaller stocks rebounded
when the Federal Reserve Board delivered a series of three short-term interest
rate cuts between September 29 and November 17, and investor confidence was
rekindled.

As of December 31, 1998
 
Throughout the year, the Fund focused on domestic companies with relatively
reliable growth rates. Consumer non-durables, business and consumer services,
and certain health care companies benefited performance. In trading activity
during the first half, a favorable housing market led us to increase our
emphasis on products for the home. Water-related companies were also added to
the portfolio, as trends to upgrade the quality of municipal water systems
became evident. Although we began the year with a below-market weighting in
technology, we significantly increased our exposure late in the third quarter
and throughout the fourth quarter.
 
REITs lagged throughout the year, so they were entirely eliminated from the
portfolio in the first half. Weightings were also reduced in
economically-sensitive industries such as metals, machinery, transportation and
energy. Grocery stocks performed very well during the year, but we reduced our
weighting in the fourth quarter, along with cash levels, as we increased
holdings in radio, finance, information technology and health care.

stocks currently provide attractive growth prospects and valuations compared to
large cap stocks.

Columbia Small Cap Fund returned 4.69% for the year ended December 31, 1998,
compared to -2.55% for the Russell 2000 Stock Index for the same period. At the
start of the year, small cap stocks reached new highs, led by companies tied to
the robust U.S. economy. The Fund benefited from an emphasis on consumer
cyclicals, such as restaurants and providers of leisure products and services,
along with certain technology issues. Performance was also helped by less
exposure to energy and energy services, as falling oil prices weighed heavily on
companies in that sector.

Concerns about the global outlook and its potential impact on corporate earnings
put pressure on the market by the third quarter. In turn, the Fund reduced
exposure to economically-sensitive areas, such as office furniture, auto parts,
semiconductor, capital equipment and construction stocks. Financial stocks were
also reduced due to concerns that their earnings growth would slow.
 
Following three short-term interest rate cuts by the Federal Reserve Board, the
stock market rebounded sharply in the fourth quarter -- further evidence of its
extreme volatility during the year. Small stocks led the charge, and the Fund
erased its negative return by gaining 17.54% in the quarter. Cash levels were
reduced to buy stocks in education, specialty retailing and information
technology consulting sectors.

In this uncertain environment, we will continue to seek companies capable of
delivering above-average earnings growth over the long term. Interestingly, 1998
marked the fifth straight year of underperformance for small cap stocks relative
to the S&P 500, and their relative valuations are at all time lows. Opportunity
exists, but a reduced level of risk aversion on the part of investors, combined
with superior earnings growth prospects for smaller companies, is needed to
spark a significant broadening of the market.

                     --------------------------------------
 
After posting two consecutive years of high double-digit returns, Columbia Real
Estate Equity Fund returned -12.33% for the 12 months ended December 31, 1998.
The Fund significantly outperformed its benchmark, the NAREIT Index, which
returned -17.51% for the same period.
 
REITs generally stumbled throughout 1998 as investors' perception about real
estate shifted sharply from previous years. Fears of overbuilding and increasing
vacancy rates, for instance, led investors to lower their expectations about
future growth of REITs. Cash flows consequently slowed and trading multiples
declined.

As of December 31, 1998
 
During this difficult year, the more defensive REIT sectors -- industrial,
retail, residential and health care -- received greater emphasis by investors,
and our significant weightings in all but healthcare helped relative
performance.  The Fund also benefited from a below-market weighting in the
lodging sector, which performed poorly all year. Although the office sector was
also a laggard, we maintained our office holdings, as we expect this sector to
improve over time, due to its prospects for internal growth and industry
consolidation.
 
Although growth rates of REITs are declining from their previously high
double-digit pace to a high single-digit pace, this trend has already been
discounted by investors in current valuations of REIT stocks. Therefore, we
anticipate that continued but slow REIT growth in 1999 and projected dividend
yields above 7% will provide a foundation for better performance in the REIT
market going forward.

Columbia Balanced Fund returned 20.07% for the year ended December 31, 1998.
Throughout this time, the Fund's asset allocation was almost evenly distributed
between stocks and bonds, with 54.5% of the portfolio at year-end attributed to
stocks, 44.0% to fixed income and 1.5% to cash.
 
On the equity side of the portfolio, we focused on larger capitalization stocks
with dependable earnings growth. Early in the year, we trimmed holdings in REITs
and electric and gas utilities, as these sectors showed signs of trouble. Our
continued focus on retail and consumer stocks benefited the Fund in the fourth
quarter, as a series of three interest rate cuts from September 29 to November
17 renewed consumer confidence.

As of December 31, 1998
 
An emphasis on certain investment themes also played a large role in stock
selection, including "The Aging of America," "Technology Age" and "Value-Added
Consolidators."
 
On the bond side of the portfolio, falling interest rates, supported by low
inflation and moderating economic growth, contributed to price appreciation of
bonds. However, prices on most bonds, including corporate and mortgage-backed
securities such as those held by the Fund, did not go up as much as U.S.
Treasuries. In the second half of the year, mortgage-backed bonds were increased
along with corporates to take advantage of upside price potential.
 
We believe the U.S. economy and corporate earnings remain vulnerable to a
worldwide economic slowdown. Although we do not anticipate a recession in 1999,
we will continue to emphasize stocks that offer dependable earnings growth in a
slowing economy. A change in monetary policy appears to be on hold for the
immediate future. We believe the Federal Reserve Board will wait for
deteriorating global economic conditions before easing again, which should keep
bond yields relatively stable in the meantime.

                     -------------------------------------
 
The U.S. Government Securities Fund returned 6.43% for the year ended December
31, 1998. This rate of return compares very favorably to inflation as measured
by the Consumer Price Index, which increased only 1.6% for the year.
 
For most of the year, interest rates across the yield curve declined. Worldwide
economic turmoil sparked a flight to U.S. Treasuries, driving their yields down,
and the Fund benefited from price appreciation. Low rates on Treasuries were
further supported by a budget surplus, which reduces the Treasury's need to
issue new bonds. Additionally, the Fund benefited from low inflation and
moderating economic growth.

The flight to quality trend that occurred for most of the year reversed somewhat
in the fourth quarter. A series of three Federal Reserve Board short-term
interest rate cuts between September 29 and November 17 rekindled consumer and
investor confidence. As investors moved money away from U.S. Treasuries into
other asset categories, Treasury prices declined and short-term Treasury yields
rose approximately 0.25% in the period.

Looking forward, we expect low inflation and moderating economic growth, which

seeks preservation of capital and income by investing in direct obligations of
the U.S. Government. These securities include Treasury bills, notes and bonds
all having a maturity of three years or less.

                  -- COLUMBIA FIXED INCOME SECURITIES FUND --
          -----------------------------------------------------------
 
The Fund returned 7.44% for the year ended December 31, 1998. Worldwide economic
turmoil led investors to U.S. Treasuries, sparking the so-called "flight to
quality" during the second half of the year. As the demand for Treasuries
increased, yields on 30-year Treasuries fell to historical levels.
 
Falling interest rates, supported by low inflation and moderating economic
growth, contributed to price appreciation of bonds. However, prices on most
bonds, including corporate and mortgage-backed securities, such as those held by
the Fund, did not go up as much as prices on U.S. Treasuries.

Since bonds are selected for the Fund's portfolio based on interest rate trends
and the liquidity of various instruments under prevailing market conditions, the
Fund rotated away from mortgage-backed securities early in the year to protect
against prepayment risk (when homeowners refinance their current mortgages to
obtain lower rates).
 
Later, mortgage-backed bonds, along with corporates, were increased to take
advantage of upside price potential and maintain an attractive yield in the
portfolio.
 
Responding to fears of economic slowdown, the Federal Reserve Board eased
short-term interest rates three times between September 29 and November 17. The
bond market fully anticipated these reductions, so interest rates reached a low
on October 5 and then rose for the remainder of the year.

The Fed appears to be on hold for the immediate future. We believe they will
wait for deteriorating global economic conditions before easing again, keeping
rates relatively stable in the meantime. At present, we continue to emphasize
high quality fixed income securities, and we are maintaining the Fund's average
maturity and duration at 6.13 and 4.86 years, respectively, in line with the
Lehman Aggregate Index, the Fund's benchmark.

                       ----------------------------------
 
Columbia Municipal Bond Fund returned 5.58% for the year ended December 31,
1998. Throughout the period, supply of new municipal debt increased sub-
stantially on a national level as municipalities refinanced existing debt to
take advantage of lower interest rates. 1998 was the second largest year ever
for new municipal issues. Cash flows into municipal bonds increased as investors
sought a safe haven from the tremendous volatility in financial markets.

In contrast, Oregon bond offerings remained fairly light in 1998, while a
generally healthy economy and increased income growth led to solid demand for
Oregon municipal bonds. This strong demand and muted supply of Oregon municipal
bonds kept their prices high compared to other states.
 
In October, long-term municipal bond yields briefly reached their lowest levels
in 10 years. Treasury yields, however, dropped more dramatically on a relative
basis, and the yield on 30-year Treasuries nearly matched the yield on 30-year
municipal bonds. Even though yields on these bonds rose somewhat later in the
year, the difference between the two yields remains historically narrow. Since
municipal bonds earn income free of federal and some state taxes, the yields
available on municipals seem attractive compared to taxable alternatives.

                         -- COLUMBIA HIGH YIELD FUND --
                         ------------------------------
 
Columbia High Yield Fund returned 6.26% for the year ended December 31, 1998.
After a strong first quarter, high yield bonds struggled in the second and third
quarters, as the supply of high yield bonds exceeded demand, and renewed
concerns about the Asian crisis prompted a worldwide flight to higher quality
bonds. Because of the Fund's focus on higher quality "junk bonds," however, the
Fund significantly outperformed its peers, as evidenced by the one-year return
of -0.08% posted by the Lipper High Yield Bond Fund Index, the Fund's benchmark.

</TABLE>
 
As of December 31, 1998
 
Responding to concerns of a worldwide economic slowdown, the Federal Reserve
Board eased interest rates a total of three times between September 29 and
November 17. The ensuing bond market rally helped to narrow the historically
high yield spreads that had developed between Treasuries and other bonds
throughout the third quarter. As yield spreads narrowed, the price of high yield
bonds increased near year-end.
 
In trading activity during the year, we increased holdings in cable TV
companies, hospital operators and food and beverage containers. Holdings in the
specialty retailing sector were reduced because of our concerns that consumer
spending might slow in 1999.

As rated by Moody's Investor Services, Inc.
</TABLE>
 
Although they have begun to narrow, the yield spreads between U.S. Treasuries
and high yield bonds are still wider than average. Since we do not anticipate a
recession in the near term, we believe the high yield market offers good
relative value compared to other bond issues.

Columbia Daily Income Company returned 5.09% for the year ended December 31,
1998.
 
Although short-term interest rates remained fairly stable for much of the year,
the Federal Reserve Board lowered short-term interest rates on three separate
occasions between September 29 and November 17 by a total of 0.75%. Money market
rates fell as a result, with the Fund's 7-day average yield declining from 5.21%
on January 1, 1998 to 4.63% on December 31, 1998.

The year was characterized by stronger than expected economic growth and
gradually declining inflation. 1998's 4.1% Gross Domestic Product growth, for
instance, compares to a slightly less robust pace of 3.8% for 1997. The 1.6%
rate of inflation for 1998, measured by the Consumer Price Index, trended
modestly lower, as the 1997 CPI was measured at 1.7%.
 
We anticipate that the economy will slow in 1999, but will still grow at a
comfortable level. With this in mind, we believe the Fed will remain on the
sidelines for awhile, opting not to adjust monetary policy unless global
economic conditions deteriorate.

                THE YEAR WAS CHARACTERIZED BY STRONGER THAN EXPECTED ECONOMIC
                GROWTH AND GRADUALLY DECLINING INFLATION.

As always, the Fund invests only in high quality, short-term debt instruments
with an average maturity of 30 to 50 days, providing a very liquid, low risk
investment. The Fund seeks to provide the highest level of income available that
is consistent with the maintenance of liquidity and preservation of capital by
investing in various money market instruments. These include commercial paper,
U.S. Treasury bills, U.S. Government agency discount notes and certificates of
deposit.

    The Columbia Funds (the Funds) consist of Columbia Common Stock Fund, Inc.
(CCSF), Columbia Growth Fund, Inc. (CGF), Columbia International Stock Fund,
Inc. (CISF), Columbia Special Fund, Inc. (CSF), Columbia Small Cap Fund, Inc.
(CSCF), Columbia Real Estate Equity Fund, Inc. (CREF), Columbia Balanced Fund,
Inc. (CBF), Columbia U.S. Government Securities Fund, Inc. (CUSG), Columbia
Fixed Income Securities Fund, Inc. (CFIS), Columbia Municipal Bond Fund, Inc.
(CMBF), Columbia High Yield Fund, Inc. (CHYF), and Columbia Daily Income Company
(CDIC). All Funds are open-end investment companies registered under the
Investment Company Act of 1940, as amended, and are diversified except CMBF,
which is non-diversified. The policies described below are consistently followed
by the Funds for the preparation of their financial statements in conformity
with generally accepted accounting principles.
 
INVESTMENT VALUATION.  The values of CCSF, CGF, CISF, CSF, CSCF, CREF and CBF
equity investments are based on the last sale prices reported by the principal
securities exchanges on which the investments are traded, or, in the absence of
recorded sales, at the closing bid prices on such exchanges or over-the-counter
markets. Securities for which market quotations are not readily available will
be valued at fair value as determined in good faith under procedures established
by and under the general supervision of the Board of Directors of each fund.
Temporary cash investments in short-term securities (principally repurchase
agreements) are valued at cost, which approximates market.
 
    CDIC investments are carried at values deemed best to reflect their fair
values as determined in good faith by or under the supervision of officers of
CDIC's investment advisor, specifically so authorized by its Directors. These
values are based on cost adjusted for amortization of discount or premium and
accrued interest, unless unusual circumstances indicate that another method of
determining fair value should be considered.
 
    CBF, CUSG, CFIS, CMBF and CHYF fixed income investments are carried at
values deemed best to reflect their fair values as determined in good faith
under consistently applied procedures by or under the supervision of officers of
the investment advisor to those Funds, specifically so authorized by their
Directors. These values are based on market value as quoted by dealers who are
market makers in these securities or by an independent pricing service unless
unusual circumstances indicate that another method of determining fair value
should be considered. Market values for CBF, CUSG, CFIS and CHYF fixed income
investments are based on the average of bid and ask prices and market value for
CMBF is based on bid prices, or by reference to other securities with comparable
ratings, interest rates and maturities. Temporary cash investments in short-term
securities (principally repurchase agreements) are valued at cost, which
approximates market.

AFFILIATED ISSUERS.  Under the Investment Company Act of 1940, as amended, an
issuer is an "affiliated issuer" of a Fund if the Fund holds 5% or more of that
issuer's outstanding voting securities or is held under common control. CSF and
CBF had investments in such affiliated issuers at December 31, 1998 as follows:

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.  CISF enters into forward foreign
currency exchange contracts to hedge certain portfolio securities denominated in
foreign currencies. Forward contracts are recorded at market value. CISF could
be exposed to risks if counterparties to the forward contracts are unable to
meet the terms of their contracts or if the value of the foreign currency
changes unfavorably. The effect of any change in the value of a hedged foreign
currency would be offset by the increase (resulting from a change in exchange
rates) in value of the securities denominated in that currency. Net realized
loss arising from forward contracts amounted to $1,097,544 and is included in
net realized loss from foreign currency transactions. CISF had no outstanding
forward contracts on December 31, 1998.

                                   CONTINUED
 
FOREIGN CURRENCY TRANSLATIONS.  The books and records of CISF are maintained in
U.S. dollars. Foreign currency transactions are translated into U.S. dollars on
the following basis:
 
 (i)  market value of investment securities, other assets, and liabilities at
      the daily rates of exchange on the valuation date, and
 
(ii)  purchases and sales of investment securities, dividend and interest income
      and certain expenses at the rates of exchange prevailing on the respective
      dates of such transactions.
 
    CISF does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of investments held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.
 
    Reported net realized foreign currency gains or losses arise from the sales
of foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on CISF's
books and the U.S. dollar equivalent of the amounts actually received or paid.
Net unrealized foreign exchange gains and losses arise from changes in the value
of assets and liabilities, other than investments in securities, resulting from
changes in the exchange rates.
 
INTEREST AND DIVIDEND INCOME.  Interest income is recorded on the accrual basis
and dividend income is recorded on the ex-dividend date. Amortization of
discount or premium is recorded over the life of the instrument. The majority of
dividend income recorded by CREF is from Real Estate Investment Trusts (REITs).
For tax purposes, a portion of these dividends consist of capital gains and
return of capital. For financial reporting purposes, these dividends are
recorded as dividend income.
 
SHAREHOLDER DISTRIBUTIONS.  CCSF, CREF and CBF distribute net investment income
quarterly and any net realized gains from investment transactions annually. CGF,
CISF, CSF and CSCF distribute net investment income and any net realized gains
annually. CDIC distributes its net investment income daily. CUSG, CFIS, CMBF and
CHYF distribute their net investment income monthly and any net realized gains
annually. Distributions to shareholders are recorded on the ex-dividend date.
 
    Income and capital gain distributions are determined in accordance with
income tax regulations, which may differ from generally accepted accounting
principles. These differences are primarily due to differing treatments for
foreign currency transactions, net operating losses, deferral of losses from
wash sales, passive foreign investment company income and return of capital
received from REITS.
 
USE OF ESTIMATES.  The preparation of the financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of income and expenses during
the reporting period. Actual results could differ from those estimates.
 
FEDERAL INCOME TAXES.  The Funds have made no provision for federal income taxes
on net investment income or net realized gains from sales of investment
securities, since it is the intention of the Funds to comply with the provisions
of the Internal Revenue Code available to certain regulated investment
companies, and to make distributions of income and security profits sufficient
to relieve them from substantially all federal income taxes.

    As of December 31, 1998, certain Funds have capital loss carryovers
available to offset future capital gains as follows:
 
<TABLE>
<CAPTION>
YEAR CARRYOVER EXPIRES     CISF        CSF       CSCF

            2006         $1,410,029 $1,021,462 $9,350,313
</TABLE>
 
    To the extent that the capital loss carryovers are used to offset any
capital gains, it is unlikely that the gains so offset will be distributed to
shareholders.
 
OTHER.  Investment transactions are accounted for on the date the investments
are purchased or sold. The cost of investments sold is determined by the use of
the specific identification method for both financial reporting and income tax
purposes. Realized gains and losses from investment transactions and unrealized
appreciation or depreciation of investments are reported on the basis of
identified costs.
 
    The Funds, through their custodians, receive delivery of underlying
securities collateralizing repurchase agreements (included in temporary cash
investments). Market values of these securities are required to be at least 100%
of the cost of the repurchase agreements.
 
    The Funds' investment advisor determines that the value of the underlying
securities is at all times at least equal to the resale price. In the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings.
 
    CHYF invests in lower rated debt securities, which may be more susceptible
to adverse economic conditions than investment grade holdings. These securities
are often subordinated to the prior claims of other senior lenders, and
uncertainties exist as to an issuer's ability to meet principal and interest
payments. At December 31, 1998, 1% of the Fund's debt securities were rated Baa,
43% were rated Ba, and 56% were rated B by Moody's Investor Services, Inc.

    In our opinion, the accompanying statements of assets and liabilities,
including the schedules of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of each of the twelve funds comprising
the Columbia Funds (the "Funds"), investment companies, at December 31, 1998,
and the results of their operations and the changes in their net assets for the
years ended December 31, 1998 and 1997, and the financial highlights for the
periods presented therein, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
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 generally accepted auditing standards which
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 owned as of December 31, 1998 by correspondence with
the custodians and brokers, provide a reasonable basis for the opinion expressed
above.
