       -----------------------------------------------------------------
 
A LOOK BACK AT 1997
 
The year was ushered in with favorable economic conditions. While the GDP
exceeded expectations in the first quarter, it was not accompanied by higher
inflation. The Fed, nevertheless, responded to the quickly growing economy by
raising short-term interest rates .25% at the end of March. This action set the
tone for a dramatic increase in stock market volatility in the second quarter
that continued throughout much of the year. Immediately after the rate hike,
both the S&P 500 and NASDAQ gave up most of their year-to-date gains, only to
have investors bid prices right back up. By the end of the second quarter, the
S&P 500 had gained 20.59%, led by a narrow group of large company stocks.

In the third quarter, the market began to broaden as investors gained confidence
about continued moderate economic growth and low inflation. Investors moved away
from large capitalization stocks to seek values in smaller cap companies and
issues overseas. Meanwhile, continuing earnings growth, expanding profit
margins, subdued inflation and low interest rates all suggested that the stock
market would prolong its historic bull run for a 13th consecutive year. Although
it appeared that the economy was approaching full utilization, there were no
signs of excess or imbalance that suggested the Fed might tighten rates in the
near term.

In the fourth quarter, currency devaluations in Southeast Asia rocked investment
communities worldwide and market volatility picked up dramatically in late
October. The financial crisis in Asian markets was aggravated by overlending and
the large amount of debt held by many private companies. At the same time,
Japan, which represents a significant percentage of the world markets, showed
renewed signs of a slowdown and this created little relief for international
investors.
 
As a result of this turbulence, a flight to safety prompted investors to migrate
back to more liquid, large capitalization stocks and to U.S. Treasuries, pushing
the yield of the long bond below 6% for the first time in almost two years.
 
MARKET OUTLOOK
 
The U.S. equity markets continue to trade at valuation levels that are
historically high, but many positive factors support these valuations. The Fed
remains vigilant, poised to tighten if economic growth or inflation heat up, but
ready to provide liquidity if the economy slows or international concerns
intensify. The current scenario -- expectations for modest increases in
corporate profits, low inflation and declining interest rates -- is generally
positive for the stock market.

                           AN OVERVIEW OF THE MARKETS
- --------------------------------------------------------------------------------
 
At this point, however, we believe that some caution is warranted. Increased
risk in the equity markets is evidenced by continued higher volatility and a
preference for greater liquidity. Concerns are growing that 1998 earnings may
not rise sufficiently to justify current prices. The potential for much slower
growth in emerging countries (particularly in Southeast Asia and Latin America)
is dimming earnings prospects for many multinational companies.
 
INVESTMENT STRATEGY
 
We have positioned our equity portfolios to favor domestic growth over cyclical
issues. Areas that merit particular emphasis, we believe, include retail issues,
health care and consumer staple stocks. Continuing strength in consumer
confidence and the low level of inflation support an overweighting in these
issues in spite of somewhat high valuations. We have increased utility stock
holdings to take advantage of their stable relative earnings and high dividend
yields. Energy issues have been deemphasized because of slowing world growth and
falling commodity prices.

REIT valuations remain attractive relative to the broader market, and
expectations for double-digit total returns are not unreasonable, with lower
volatility than the S&P.
 
As we look to the year ahead, we continue to believe that economic indicators
support prospects for a healthy economy. However, peaking profit margins and
slowing world growth should, we believe, lead to moderating corporate earnings
growth. We anticipate the recent high level of market volatility to continue, so
we remain focused on companies that are expected to maintain competitive
strength in their industries and deliver dependable earnings growth.
 
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 1997, 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.

For the third consecutive year, Columbia Common Stock Fund delivered gains in
excess of 20% by posting a total return of 25.37% for 1997. The strongest
performing sectors included banking and finance, consumer staples and retailers.
Sectors that did not perform as well included energy, REITs and cyclicals like
paper and metals.
 
After maintaining a steady weighting in cyclical stocks, we adopted a growth
strategy early in the fourth quarter, in anticipation of a slowing economy. To
that end, stocks in the building, forest product, metal and chemical sectors
were reduced from a total of 16% of the portfolio to 3%. We also reduced
positions in energy and technology stocks. Consumer staples, health care and
utilities, on the other hand, were increased.Our investment strategy assumes
that profit growth in 1998 will be more difficult for domestic companies to
attain. With low inflation and low interest rates, price earnings ratios will
most likely hold steady for companies delivering good earnings growth. We also
believe that market volatility, which has been below average over the last few
years, will likely increase to more normal historical levels, making it more
important to manage risk and to identify companies with the most reliable growth
prospects. With this in mind, we are focusing on areas that are expected to
benefit from steady earnings in a slow growth environment.
 
With a median market cap of $10.6 billion, Columbia Common Stock Fund is well
diversified with over 78 different issues at year-end. The Fund continues to
seek growth of capital and dividend income by using a top down, sector rotation
strategy to select stocks of large, well-established companies.

Columbia Growth Fund gained 26.32% for the year ended December 31, 1997. Drug,
bank, insurance and consumer growth stocks contributed to positive performance
during the year, while REITs, health care service, and most technology stock
returns lagged.
 
The Fund's overall positive performance was attributable to rising P/Es due to
lower inflation expectations and good corporate earnings growth. In 1997, the
Fund's return lagged the S&P 500 Stock Index where a relatively small number of
the largest capitalization stocks in the Index posted superior performance
compared to the broader market. Nevertheless, we remain confident that
fundamentals of the stocks in Columbia Growth Fund -- lower valuations and
superior earnings growth -- are more attractive than the larger company stocks
in the Index, and will reward shareholders of the Fund.

We expect corporate earnings growth to slow as profit margins peak and as demand
slows due to economic and currency turmoil in Southeast Asia. Events in that
region have lowered inflation expectations even further, however. Therefore,
interest rates could stay at current low levels, helping to support the
relatively high valuations seen in the stock market.
 
With a view toward less earnings growth and lower interest rates, we are
emphasizing stocks from companies with relatively stable growth. With the Asian
situation negatively affecting exporters, as well as those companies that
compete with imports and that do business in Asia, we expect superior growth to
come from more domestically-oriented companies and those multinational companies
selling such nondurable items as drugs and various household items.
 
With a median market cap of $9.6 billion, Columbia Growth Fund continues to be
well diversified with 81 different holdings as of December 31, 1997.

The Columbia International Stock Fund enjoyed strength in the first half of the
year, where gains were fueled by double-digit returns in Europe, Brazil, India,
Taiwan and Korea. The second half of the year grew turbulent, however, as a
result of volatile and weak Asian markets, and the Fund recorded a 1997 total
return of 11.47%.
 
On early signs of turmoil in Southeast Asia, we sold positions in Korea,
Malaysia, Hong Kong, and Taiwan in the third quarter, but the Fund was still
negatively impacted. By October, the Asian financial crisis had spread to Hong
Kong, and many major stock markets weakened, including Japan, which showed
further signs of economic malaise. Led by the United States, however, most of
these markets recovered to end the year on a more positive note.
 
Despite a weak international market, Columbia International Stock Fund
outperformed its benchmark for the period. Not only did the Fund underweight
Japan, but stock selection

emphasized exporting companies such as electronics and autos, which enabled the
Fund's Japanese holdings to outperform the overall Japanese market. Also, above-
market weightings in several smaller European markets (Sweden, Norway, Spain and
Italy) helped performance. With the European Monetary Union underway (a movement
toward one currency), European markets remain attractive as bond yields converge
and many countries experience huge declines in interest rates.
 
We approach the new year with uncertainty about when the Asian financial crisis
will be resolved. Nevertheless, many global markets show promise. Europe's
recovery is gaining momentum and we look for more domestic policy change in
Japan that should aid the entire Asian region. The Fund will continue its
objective of seeking long-term capital appreciation by investing primarily in
stocks of companies based outside the U.S. with at least 75% of the portfolio
invested in companies with market valuations over $500 million.

The Special Fund generated a total return of 12.64% for the 1997 year. During
the fourth quarter, small- and mid-cap stocks underperformed the large-cap S&P
500 Stock Index. This came after an unusually strong third quarter of
outperformance, which was fueled by a market rotation away from highly valued
large cap stocks.
 
The Fund's performance was adversely affected during the year by an early
emphasis in the paper and metal sectors. We believed that these economically
sensitive industries would offer value by benefiting from stronger than expected
economic growth. In addition, we chose to de-emphasize finance stocks throughout
the year in anticipation that these fully priced securities would disappoint if
interest rates increased due to the strong

world economic growth. The demand for basic materials was reduced by the
international slowdown, and this prompted a decline in domestic and foreign
interest rates. In turn, investors fled from companies with less predictable
earnings to those with more consistent growth.
 
As the year came to a close, we sharply reduced our weightings in paper, metals
and machinery from a total of 24% of the portfolio to 7%. We increased areas of
steady growth like business and consumer services, consumer staples and health
care from 30% of the portfolio to 46%. We also added to REITs and are currently
maintaining a below-market weighting in technology.
 
The long-term strategy of the Special Fund has always been to maintain a core of
growth stocks while anticipating and recognizing changes in the market. This has
enabled us to invest in sectors and themes that benefit from these changes. As
we begin 1998, we are emphasizing consistent growth stocks, domestic companies,
and risk management. This supports our outlook for low inflation, a reduced rate
of corporate profit growth and the likelihood of greater stock market
volatility.

For 1997, Columbia Small Cap Fund generated a total return of 34.10%,
outperforming both the S&P 500 and the Russell 2000. After particularly strong
performance in the second and third quarters, however, the Fund suffered in the
fourth quarter when small cap stocks sputtered in response to increased stock
market volatility.
 
Investment themes benefiting the portfolio during the year included a focus on
specialty retailers based on a high level of consumer confidence and spending.
We also emphasized the assisted living sector as part of our emphasis on the
aging of America. Another successful strategy was to invest in stocks of well-
drilling and oil equipment supply industries, which provided handsome returns.

During the fourth quarter, turmoil in Southeast Asian economies prompted
investors to seek a safe haven in larger, more liquid stocks.
 
The demand for liquidity depressed small cap valuations and thus stock prices.
We responded by selling stocks we believed were fully valued and susceptible to
correction, along with those we deemed most vulnerable to negative earnings
revisions from the Asian crisis. These areas included energy and certain
segments of the technology sector. Meanwhile, we increased our health care
exposure due to this sector's more stable domestic revenue base and insulation
from the economy.
 
Looking ahead, we believe that relative valuations and earnings growth prospects
in the small cap market are attractive based on historical ranges. In the
meantime, the Fund continues to employ fundamental research to identify
attractively valued, small companies with above average earnings potential.
Using a bottoms up approach to stock selection, the Fund had a diversified
portfolio of 101 issues at year-end and a median market capitalization of $551
million.

Columbia Real Estate Equity Fund posted a total return of 24.74% for the year
ended December 31, 1997. Real estate investment trusts (REITs) corrected early
in the second quarter, along with the rest of the stock market, as investors
adjusted to the March 25th rate hike by the Federal Reserve Board. Second
quarter money flows into REITs subsequently slowed as investors turned their
attention to the rebounding S&P 500.
 
In the third quarter, momentum in the REIT sector resumed, and performance was
led by investments in the office, hotel and industrial sectors. We maintained an
overweighting in these areas as their internal and acquisition growth
fundamentals suggested positive future performance.

A below-market weighting in health care and lagging performance in the office
sector penalized the portfolio in the fourth quarter.
 
Overall, investor interest in REITs grew significantly in 1997. Money flows into
REIT mutual funds were healthy, approaching $5 billion for the year. In
addition, market capitalization for the REIT sector jumped 60% to stand at $145
billion by year-end.
 
In an environment where the earnings growth of the broader market is coming into
question and S&P 500 dividend yields are at historic lows, we believe that REITs
offer attractive total return potential for investors looking to diversify their
portfolios.

Columbia Balanced Fund returned 18.74% for the 1997 year. While large company
stocks led the market in the first half, we maintained a market underweighting
in them because we believed much of their price appreciation was unrelated to
improving fundamentals. Not surprisingly, large company stocks corrected in the
third quarter, as investors questioned the continued earnings growth of this
richly valued sector. In the fourth quarter, however, market turmoil in
Southeast Asia prompted investors to migrate back to large company stocks in
search of greater liquidity.
 
Overall, the equity portion of the portfolio benefited from holdings in
financial services (Freddie Mac), diversified manufacturing (General Electric
and Tyco Intl.), and consumer goods and services (Mattel and Service Corp.
Intl.), due to their relative immunity to economic turmoil outside the U.S.

Economically sensitive cyclical stocks were influenced by volatile activity
overseas, and portfolio holdings in these sectors suffered. Growth slowed
worldwide, particularly in a number of natural resource-hungry developing
countries.
 
Concern about lower commodity prices led the Fund to reduce exposure to energy,
forest products and chemical industries. In light of the rapid economic slowdown
in Southeast Asia, technology holdings were scaled back late in the year,
reflecting a growing concern about earnings expectations.

Columbia Daily Income Company generated a total return of 5.11% for the twelve
months ended December 31, 1997. This rate of return compares favorably to the
rate of inflation as measured by the Consumer Price Index (1.7%).
 
During the year, the Fund's 7-day average yield rose from 4.87% in January to
5.21% at year-end. While long-term interest rates declined during the year,
money market rates rose slightly due to the Federal Reserve Board's .25%
increase in the Federal Funds rate in March. In addition, the supply of short-
term instruments later in the year was particularly strong, driving up the
yields on money market instruments in December.

Because of the subdued rate of inflation, the Federal Reserve Board has left
short-term rates untouched since March 25, despite a steadily growing economy.
The outlook for short-term rates remains unchanged for the next few months.
 
As always, Columbia Daily Income Company 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.
                AT THIS TIME, MONEY MARKET YIELDS ARE VERY ATTRACTIVE RELATIVE
                TO THE EXPECTED RATE OF INFLATION.

modestly growing economy was not being accompanied by a strong threat of

Continued economic growth combined with low inflation has caused the Federal
Reserve Board to keep interest rates unchanged since March 25th. With market
turmoil in Southeast Asia, short-term Treasuries, such as those held by the
Fund, are often viewed as a safe haven for investors.

                  -- COLUMBIA FIXED INCOME SECURITIES FUND --
                  -------------------------------------------
 
For 1997, Columbia Fixed Income Securities Fund posted a total return of 9.56%.
Although bonds suffered early in the year under pressures of a rapidly growing
economy and rising interest rates, the bond market closed the year with a
powerful rally triggered by market turmoil in Southeast Asia.
 
After a volatile first quarter, bonds responded positively in the second and
third quarters to a moderately growing economy with little sign of inflation. As
worldwide stock market volatility intensified in the fourth quarter, investors
sought refuge in fixed income. To take advantage of the changing dynamics in
this arena, we initiated several shifts in asset allocation. For instance, the
yield differential between mortgages and Treasuries fluctuated periodically
throughout the year, providing us with opportunities to increase mortgage
weightings when prices were low, and decrease mortgage weightings (take profits)
when prices crept up. As interest rates dropped in the fourth quarter, we
reduced the average coupon (fixed interest rate paid on bonds) of mortgage
securities in order to stave off any price deterioration resulting from
homeowners refinancing their mortgages (prepayment risk).

The corporate bond sector became attractive when their prices declined relative
to Treasuries. We then increased the corporate bond weighting by approximately
3% in the fourth quarter, mostly in the finance sector. Short-term asset-backed
securities, such as home equity loans, performed quite well in the fourth
quarter, and we took profits in this sector.
 
The Fund invests in a broad range of fixed income securities. At least 95% of
assets are invested in debt securities rated Baa or higher, although the vast
majority is usually invested in securities rated A or higher. The average target
maturity and duration of the Fund are approximately 5.5 years and 4.6 years,
respectively, which is slightly longer than the Fund's benchmark, the Lehman
Aggregate Bond Index.

Columbia Municipal Bond Fund returned 8.36% for the twelve months ended December
31, 1997. During the first half of the year, fixed income securities experienced
price volatility as first quarter economic growth exceeded expectations and the
Federal Reserve Board hiked short-term interest rates by .25% to ward off
inflation. Bonds recovered from this volatility in the second quarter, and
continued to appreciate in the third quarter as moderate growth persisted with
little sign of inflation. As a result, interest rates on long-term municipal
securities fell approximately .20% by September 30.

In the fourth quarter, volatility in the international markets prompted a flight
to high quality U.S. Treasuries, further driving bond prices up and yields down.
With concern about a delayed recovery in Southeast Asia, investors have lowered
their expectations for corporate earnings growth in 1998. These concerns,
combined with low reported inflation and a reduced federal budget deficit (which
will
 
lower the supply of Treasuries going forward), sent Treasury and municipal
yields to lower levels by year-end. Yields on municipal securities fell another
 .20% during the fourth quarter, pushing down 30-year municipal bonds to their
lowest yields in 10 years.
 
The supply of new Oregon bonds remains low, as voters hesitate to approve new
taxes. With low interest rates, however, we anticipate that the supply of new
Oregon bonds will increase as older issues are refunded and issuers take
advantage of lower rates.
 
In trading activity during the year, we endeavored to replace short-term, pre-
refunded bonds with longer term, higher yielding bonds to lock in higher rates
in a declining interest rate environment. At year-end, the average maturity of
the Fund's portfolio was intermediate term, at 11 to 12 years, and its duration
was approximately 6.5 years. As always, the Fund maintains a high average credit
quality and is broadly diversified within the State. We remain committed to
providing shareholders with high, after tax returns combined with a low level of
credit risk and low volatility.

The Fund posted a total return of 12.70% for the twelve months ended December
31, 1997. Early in the year, the fixed income market suffered from a rapidly
expanding economy and rising interest rates. But as bond investors began to
realize that growth would not be accompanied by higher inflation, bond prices
appreciated throughout the year. As in 1996, the high yield sector of the bond
market again outperformed investment-grade bonds in 1997. This caps off several
consecutive years of solid performance by high yield bonds, thanks to positive
fundamentals and growing investor interest. In 1997, for example, the high yield
market grew by over 26% with $135 billion in new issues coming to market from
over 700 issuers. Flow of money into high yield funds rose by 42% during the
year to $22 billion, as investors continued to view high yield bonds as
excellent tools for diversification.
 
In trading activity, positive fundamentals led us to emphasize the media sector
throughout much of the
                              SECTORS OF EMPHASIS

year with particular emphasis in broadcasting. We also favored specialty
retailing and entertainment, both of which contributed positively to Fund
performance. As commodity prices came under pressure in the fourth quarter
because of the currency crisis in Southeast Asia, bonds in the energy sector
were pared back. To reduce exposure to economically sensitive issues on the
chance that economic growth will moderate, we also reduced bonds issued by
companies in cyclical industries like paper and chemical.
 
For the coming year, favorable conditions such as continuing economic growth,
low inflation, and positive cash flows into high yield mutual funds should
continue to make this market attractive for the near term.

    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 Daily Income Company (CDIC), Columbia U.S. Government
Securities Fund, Inc. (CUSG), Columbia Fixed Income Securities Fund, Inc.
(CFIS), Columbia Municipal Bond Fund, Inc. (CMBF), and Columbia High Yield Fund,
Inc. (CHYF). 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 in 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. 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, 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, 1997 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
gains arising from forward contracts amounted to $241,528 and are included in
net realized gain from foreign currency transactions. As of December 31, 1997,
CISF had entered into the following forward contract resulting in net unrealized
appreciation of $129,673.

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 securities held. Such changes are
included with the net realized and unrealized gain or loss from investments.
 
    Reported net realized foreign currency gains or losses arise from 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 respective 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 -- including any
realized investment gains or losses. 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 revenues 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 securities, since
it is the intention of the Funds to comply with the provisions of the Internal
Revenue Code available to certain 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, 1997, CUSG has $242,419 in capital loss carryovers
available to offset future capital gains which expire in 2002.
 
    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, 1997, 41% of the Fund's debt securities were rated Ba
and 59% were rated B by Moody's Investor Services, Inc.

The investment advisor of the Funds is Columbia Funds Management Company (CFMC).
The transfer agent for the Funds is Columbia Trust Company (CTC), a majority
owned subsidiary of CFMC. The transfer agent is compensated based on a per
account fee.
 
On December 10, 1997, CFMC, CTC and Columbia Management Company (CMC), an
affiliated company, became
- --------------------------------------------------------------------------------
indirect subsidiaries of Fleet Financial Group, Inc. (Fleet), a publicly owned
multi-bank holding company registered under the Bank Holding Company Act of
1956. Prior to that date, certain officers and directors of the Funds were also
officers and directors of CFMC, CTC and CMC. Those individuals did not receive
any compensation or other payment from the Funds. As a result of federal banking
regulations, no officers or directors of the Funds are officers or directors of
CFMC, CTC or CMC following the transaction with Fleet. J. Jerry Inskeep, Jr., an
officer and director of the Funds, is affiliated with Fleet, but receives no
compensation or other payment from the Funds.
 
As a result of the transaction with Fleet, directors of the Funds were required
to approve new contracts for investment advisory and transfer agent services
between the Funds and CFMC and CTC, respectively. These new contracts are the
same in all material respects to the corresponding previous contracts.
Shareholders of the Funds were required to approve the new investment advisory
contracts. The proxy voting results of the approval by shareholders of the Funds
of those contracts is set forth at the end of this 1997 Annual Report.

    We have audited the accompanying statements of assets and liabilities,
including the schedules of investments for each of the twelve funds comprising
Columbia Funds (the "Funds"), as of December 31, 1997, the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, except for CSCF which is for the
period from inception, September 11, 1996 to December 31, 1996 and for the year
ended December 31, 1997 and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodians and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
twelve funds comprising Columbia Funds enumerated above as of December 31, 1997,
the results of their operations for the year then ended, the changes in their
net assets for each of the two years in the period then ended, except for CSCF
which is for the period from inception, September 11, 1996 to December 31, 1996
and for the year ended December 31, 1997 and the financial highlights for each
of the periods indicated therein, in conformity with generally accepted
accounting principles.

       -----------------------------------------------------------------
 
    On December 4, 1997, the Funds held a Special Meeting of Shareholders to
approve new investment advisory contracts with the Advisor. The need to approve
a new investment advisory contract was caused by the change in control of the
Advisor resulting from the acquisition of the Advisor by Fleet Financial Group,
Inc. A new investment advisory contract was approved by each Fund as shown
below:
