                           AN OVERVIEW OF THE MARKETS
       -----------------------------------------------------------------
 
A LOOK AT THE FIRST HALF
 
While propelled to new highs during the first half of the year, the stock market
exhibited considerable volatility in the second quarter, amid renewed concerns
about the deepening financial crisis in Asia and expectations for slower
corporate profit growth. In spite of these worries, the S&P 500 rose 17.71% for
the six months ended June 30, 1998. Although the S&P 500 continued to advance,
the breadth of the market deteriorated significantly late in the half, with
large retail, health care, technology, and finance stocks posting the strongest
returns, while REITs, basic material, energy, transportation and utility names,
as well as smaller cap companies, lagged.
 
Optimism from early in the year was tempered in the second quarter as evidence
began to mount that problems overseas could have a substantial negative impact
on the U.S. economy. By mid-June, the Japanese yen had weakened appreciably.
Fearing that the sliding yen would trigger devaluations in other Asian
currencies, the U.S. and Japanese governments joined forces to intervene in the
currency markets, stabilizing the yen for now. Despite moves by the Japanese
government to reform the financial system, there is unlikely to be a quick fix
for the economic downturn in Japan, and this may hinder a recovery in other
Asian countries.
 
Europe seems to be a bright spot internationally. Many European companies have
restructured their business operations, cutting costs and increasing profits.
The financial crisis in Russia has little impact on U.S. trade and capital
flows, but much more on European countries. World economic growth is slowing,
which has strong implications for U.S. markets because corporate earnings have
become increasingly dependent on revenues derived from overseas markets. The
financial crisis in Asia has caused a sharp worsening in the trade balance.
This, together with high inventories and a strong dollar, signals potential
earnings trouble for some business sectors. These concerns have contributed to a
lowering of corporate earnings estimates for the second quarter and are expected
to lead to lower estimates for the remainder of 1998 and 1999.

POSITIVE FACTORS STILL INTACT
 
Nevertheless, many positive fundamentals remain in place. Although inflationary
pressures in the service sector have risen somewhat and the Consumer Price Index
has moved modestly higher, inflation remains quite low. The Fed is watching
economic indicators closely, but absent any significant change in economic
activity, is widely expected to keep short-term interest rates around current
levels. Long-term rates are near 27-year lows. While corporate earnings growth
is expected to slow, it should remain modestly positive for the year. Apart from
the near-term uncertainty, the crisis in Southeast Asia is having some
stimulative effects in the U.S., with low commodity prices and cheaper imports
contributing to lower inflation. Additionally, foreign investments in the U.S.
financial markets have increased as investors seek a safe haven.

FOCUS ON DEPENDABLE GROWTH
 
Moderating economic growth and substantial risk from events overseas have led us
to emphasize companies with superior earnings growth prospects and lower
vulnerability to negative surprises. We expect larger companies with dominant
competitive positions and earnings derived primarily from the U.S. or Europe to
be most likely to deliver solid growth.
 
Columbia's focus is on stocks we expect to be favorably influenced by our
current investment themes, in particular, "Aging of America," "Technology Age,"
and continued merger and acquisition activity. The demographic trend of "Aging
of America" favors the health care, financial services and leisure sectors that
sell products to the fastest growing segment of the population. Companies poised
to profit from the "Technology Age" theme include those in the
telecommunications, computer software, networking and internet industries.
Additionally, due to unflagging consumer demand, we have kept the portfolios
overweighted in retail stocks compared to the broader market.
 
INFLOWS INCREASE TO BOND FUNDS
 
As stock market volatility and economic uncertainty have increased, inflows to
bond mutual funds have picked up. Although interest rates are at historic lows,
inflation-adjusted yields on bonds (real rates) look attractive, well in excess
of the long-term average. The long-term deflationary trend of prices is expected
to continue, with inflation rising quite modestly this year.
 
The Treasury's reduced demand for funds, as the federal budget moves into a
surplus, is a long-term positive for the bond market. The surge in corporate
debt issuance so far this year may wane if corporate capital spending declines
on weakening profits. New corporate debt has easily offset the reduced Treasury
offerings year-to-date.
 
So that you may evaluate how the Columbia Funds have performed given this
economic and financial market backdrop, the following pages contain discussions
of the Funds' investment activity for the six months ending June 30, 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, porfolio transaction costs or cash flows.
 
At Columbia, our goal has always been to provide you with the best long-term
returns possible, with an emphasis on managing investment risk. We remain
committed to meeting your financial objectives and we appreciate your continuing
trust.

                        --------------------------------
 
For the six months ended June 30, 1998, Columbia Common Stock Fund had a total
return of 15.68%. While marked by increased volatility, the stock market was
propelled to new highs during the period, fueled by such favorable conditions as
low inflation, moderate economic growth and low interest rates. In this
environment, there were some sectors that experienced better earnings growth
than the broader market, including technology, consumer cyclical and staple
stocks. Our continued emphasis in these areas, as well as in stocks with
consistent earnings growth, benefited Fund performance during the period.

As of June 30, 1998
 
As always, investment themes derived from our view of the macroeconomic
environment played a significant role in the portfolio. For example, the "Aging
of America" theme hinges on the changing spending patterns of the maturing Baby
Boom generation. This demographic shift provides a tailwind for companies that
provide products and services to aging Americans.
 
Another important investment theme is the "Technology Age," which attempts to
capture the long-term changes occurring in technology and related sectors. Our
current strategy is to concentrate on companies poised to profit from corporate
spending priorities in internet/e-commerce, telecommunications deregulation, the

Near term, we anticipate continuing low inflation, with earnings growth becoming
more difficult to attain. This is especially true in light of the uncertainty
associated with the Asian currency crisis. With this in mind, we are bypassing
cyclical stocks in favor of reasonably valued, domestic-oriented companies that
offer more dependable earnings growth prospects.

Amid increased market volatility, Columbia Growth Fund returned 21.55% for the
six months ended June 30, 1998, outperforming the S&P 500, which returned 17.71%
for the same period. The Fund's performance was supported by high returns from
Warnaco, Cisco Systems, Pfizer, and Microsoft, among others. Themes driving
stock selection included a focus on industries that stand to benefit from the
demographic trend of the aging of America and those that are poised to profit
from technological change, including internet commerce.

The trend of lower interest rates has stimulated mortgage refinancing, and a
rise in personal wealth (due to higher stock prices) has increased consumer
spending. Anticipating strength in consumer spending, the Fund increased its
exposure to domestic and consumer issues in late 1997, and this benefited
performance during 1998. Our continuing analysis of the investment environment
has also resulted in an emphasis on health care, consumer staples, retail,
business, and segments of technology and financial stocks.

While renewed concerns about the Asian financial crisis and continued
expectations for slower corporate profit growth contributed to greater market
volatility in the second quarter, many favorable conditions still exist. Strong
cash flows, sound monetary policy, strong balance sheets, low inflation and
falling interest rates all help support continued expansion of the stock market,
the economy and corporate earnings, but at a slower pace.
 
As always, the Fund seeks long-term capital appreciation by investing primarily
in common stocks believed to offer above average earnings growth.

For the six months ended June 30, 1998, the Fund posted a total return of
13.07%. After a slow start at the beginning of the year, Columbia International
Stock Fund had a good second quarter, strongly outperforming the FT/S&P
Euro-Pacific Index. During this time, we reduced the Fund's holdings in Japan in
favor of investments in the better performing European markets. This was an
important contributor to performance during the second quarter.

European markets have been responding well to the impending European Monetary
Union, which will introduce a single currency for all participating countries in
January 1999. Preparation for the EMU has fostered low interest rates and
disciplined fiscal policies, while providing a strong platform for renewed
economic growth in the region. Furthermore, individual investors throughout
Europe are participating in the markets more fully than ever before, taking
advantage of new tax-favored savings programs similar to the American IRA. Most
importantly, economic growth continues to accelerate, and we expect that this
trend will continue to support higher European stock prices for the balance of
the year.

Although the Japanese and Southeast Asian markets experienced surprisingly sharp
gains in the first quarter, continued economic decline in Southeast Asia and
stagnation/deflation in Japan caused emerging markets to retreat dramatically
during the second quarter. Meanwhile, under pressure from other countries, the
Japanese government appears to be preparing legislation to resolve its banking
crisis. With some important policy changes, this depressed market could rebound.
We plan to carefully watch developments unfold, but a relatively low exposure to
Japan seems appropriate for now.

While the stock market started the year off sharply, small and mid-cap stocks
gave up some of their early gains during a volatile second quarter. For the six
months ended June 30, 1998, Columbia Special Fund was up 8.64%, compared to
4.93% for the Russell 2000.
 
Throughout the period, we focused on industries that tend to show consistent
earnings growth, especially those with a domestic orientation and limited
exposure to Asia. This strategy was shaped by our expectations for a
deceleration in corporate profits and increased risk of earnings
disappointments. Business and consumer services, consumer nondurables and
certain health care companies were strong performers during the period, while
REITs vastly underperformed the broader equity market.

In trading activity, we took profits in a number of apparel retailers and
increased our emphasis on companies that manufacture and sell products for the
home. We believe that a favorable housing market and greater consumer interest
in home furnishings will benefit these stocks. We also increased our holdings in
water-related companies, as more money is being spent to upgrade the quality of
municipal water systems. Also, we increased our holdings in technology, using
the proceeds from the positions we liquidated in the underperforming REIT sector
to fund our technology additions. Finally, we refocused our finance sector
weightings away from regional bank stocks to insurance stocks, which show
potential for having above-market earnings growth.

                         -----------------------------
 
As investors sought increased liquidity in a volatile stock market environment,
small cap stocks lagged larger company issues. For the six months ended June 30,
1998, the Fund had a total return of 8.89%, significantly outperforming its
benchmark index, the Russell 2000 at 4.93% for the same period. This compares to
the S&P 500's total return of 17.71%.
 
Early in the period, small cap stocks reached new highs, led by companies tied
to the robust U.S. economy. Consumer cyclicals, such as retailers and providers
of leisure products and services were especially strong, as were issues of
certain technology companies, both of which we emphasized during the period. The
Fund also benefited from reduced exposure to energy and energy services, as
falling oil prices weighed heavily on the shares of companies in this sector.

May ushered in a spate of new worries related to Asia and the prospects for
corporate earnings, causing a downdraft in price/earnings multiples through the
end of the first half of the year. However, there are a number of positive
factors in place that could contribute to improved small cap performance. For
example, earnings growth for small companies is currently quite strong and is
starting to expand relative to the earning forecasts for companies in the S&P
500. Plus, low interest rates and a moderately growing economy tend to benefit
the type of growth stocks we now favor in the Fund, since their earnings are
less dependent on the economic cycle.

As far as the future is concerned, we are focusing on companies that are
expected to deliver above-average earnings growth. We are also evaluating
"cyclical-growth" companies, such as those that manufacture semiconductors, for
signs of a possible recovery in their fundamentals. Overall, we believe that
relative valuations and earnings growth prospects in the small cap market are
attractive based on historical ranges.

For the six months ended June 30, 1998, Columbia Real Estate Equity Fund had a
total return of -4.34%. That compares to a total return of -5.03% for the
NAREIT Index over the same period.
 
REITs significantly lagged the broader equity market for the first half of the
year. This underperformance was largely attributable to increasing concerns that
the recent strong earnings growth enjoyed by REITs would slow sharply going
forward, as real estate acquisitions become increasingly expensive and new
development threatens the supply/demand balance for real estate.

As of June 30, 1998
 
Performance in the REIT market was led by the more defensive retail sector,
where strong consumer spending bolstered fundamentals. The high growth office
and lodging sectors lagged during the period -- evidence of investors' concerns
about potential overbuilding and increasing vacancy rates.
 
Throughout the period, however, we maintained a sizable weighting in the office
sector, believing that the positive prospects for internal growth and industry
consolidation in this sector remain intact.
 
We believe that the current valuations for REITs reflect an overdiscounting by
investors anticipating slower industry growth. Many REITs, in fact, are now
trading at or below the underlying value of the real estate they own. We believe
that these valuations are attractive and, along with rising dividend growth
rates, may provide the opportunity for better performance in the months ahead.

Our focus going forward will center on companies that can produce growth in a
real estate environment that is reaching the mature stage of its business cycle.
The management of the companies we seek for the portfolio will have demonstrated
the ability to sustain healthy internal growth while adding value through
selective development activity.

Columbia Balanced Fund posted a total return of 11.70% for the six months ended
June 30, 1998. During this time, the stock market reached new highs, with the
Dow Jones Industrial Average surpassing the 9000-point mark for the first time
in April, thanks to such favorable conditions as low inflation, moderate
economic growth and low interest rates. In this environment, certain sectors
experienced better earnings growth than the broader market, including
technology, consumer cyclical and staple stocks. Our continued emphasis in these
areas, as well as in stocks with consistent earnings growth prospects, benefited
Fund performance during the period. Lagging sectors, on the other hand, included
REITs, energy and electric and gas utilities.

Because we anticipate continuing low inflation with earnings growth becoming
increasingly difficult to attain, we are avoiding cyclical stocks, which tend to
rise quickly when the economy is on the upswing and fall when the economy turns
down. Instead, we are seeking stocks with reasonable valuations, which offer
more dependable earnings growth.
 
On the fixed income side of the portfolio, bonds rallied as long-term Treasuries
fell to a low of 5.62%. Although prices on most bonds increased during the
period, corporate and mortgage-backed securities did not go up as much as
Treasuries, presenting an opportunity to increase weightings in these sectors.

While we do not anticipate much change in the low level of bond yields over the
next few months, we believe bond yields will continue to offer value when
compared to the rate of inflation.

Columbia Daily Income Company posted a total return of 2.52% for the six months
ended June 30, 1998, comparing favorably to the rate of inflation, which was
just .7% during the same period, as measured by the Consumer Price Index. The

With continued low inflation, the Federal Reserve Board has opted to leave
short-term rates untouched for the past 15 months, despite a steadily growing
economy.
 
Economic growth has begun to slow, however, which should keep the Fed from
increasing rates in the immediate future. As an example, annualized GDP growth
for the second quarter is expected to slow dramatically from the very brisk pace
of 5.4% reported for the first quarter.
                AT THIS TIME, MONEY MARKET YIELDS ARE VERY ATTRACTIVE RELATIVE
                TO THE EXPECTED RATE OF INFLATION.

As always, the Fund invests only in high quality, short-term debt instruments
and maintains a dollar-weighted average maturity of 30 to 50 days, providing a
very liquid, low risk investment.

Columbia U.S. Government Securities Fund posted a total return of 2.61% for the
six months ended June 30, 1998. Interest rates across the entire yield curve
declined during the period. The very low level of inflation and expectations for
economic slowing convinced the Federal Reserve to leave short-term interest
rates unchanged. However, this more positive backdrop for the bond market led to
lower rates on short-term Treasuries, and the Fund benefited from some price
appreciation over the period.

Annualized GDP growth for the second quarter is expected to slow dramatically
versus the brisk pace of 5.4% reported for the first quarter. Further economic
slowing could mitigate the need for the Federal Reserve Board to tighten
monetary policy in the near term. In addition, the turmoil in Asia has increased
uncertainty about the prospects for U.S. economic growth, which should also
contribute to stable rates in the near term.

The bond market rallied during the first half of the year, as long-term Treasury
yields fell to a low of 5.62%. The strength of the bond market was largely
attributable to a combination of favorable fundamental and technical factors.
Low inflation and moderating economic growth provided a solid backdrop for low
rates. In addition, the expected Federal budget surplus has reduced the
Treasury's need to issue new bonds, thus reducing the overall supply as older
bonds mature. The strong U.S. dollar, relatively high nominal interest rates and
turmoil in Asian markets have prompted investors to favor dollar-denominated
instruments, such as those we hold in the portfolio. For the six months ended
June 30, 1998, Columbia Fixed Income Securities Fund posted a total return of
3.72%.

Although prices on most bonds increased during the period, corporates and
mortgages did not go up as much as Treasuries. We believe these sectors
represent value. To capitalize on this buying opportunity, we increased our
weightings in both corporates and mortgages. While we do not anticipate much
change in the low level of bond yields over the next few months, we believe
yields will continue to offer value when compared to the rate of inflation.

                       ----------------------------------
 
Columbia Municipal Bond Fund's total return for the six months ended June 30,
1998 was 2.09%. Overall, municipal securities have tended to underperform the
broader fixed income market as the national supply of municipal bonds has
continued to exceed demand. The outlook improved in the second quarter, however,
as yields on national municipal securities fell on declining interest rates,
although not as much as Treasury bond yields. This makes the price of municipal
bonds look relatively attractive on a historical basis (when yields fall, prices
rise) compared to taxable bonds and inflation.

The Oregon economy remains healthy, and increasing income growth in the last few
years has led to strong demand for municipal bonds within the State. Unlike the
national municipal market, the supply of new bonds in Oregon has been muted so
far this year. However, the number of new issues may increase if interest rates
stay at these low levels or fall further, prompting refinancing of existing
debt.

                         ------------------------------
 
Columbia High Yield Fund provided a total return of 4.45% during the six months
ended June 30, 1998. After a strong first quarter, high yield bonds struggled a
bit in the second quarter, as investors became increasingly concerned about the
impact of the Asian crisis on U.S. economic growth and corporate earnings. In
addition, high yield bonds were negatively impacted by the large supply of new
deals brought to market during the second quarter. This environment prompted a
flight to quality within the high yield market and increased the demand for junk
bonds with higher credit ratings. This benefited Fund performance, due to our
focus on higher quality issues in the high yield market.

As of June 30, 1998
 
As corporate prices fluctuated throughout the period, we found attractive
investment opportunities in several new issues. In early 1998, we purchased
holdings in the aerospace sector. We believe the long-term prospects for the
aerospace industry are favorable due to stronger demand for new aircraft and
parts, as airline fleets around the world age and airline travel increases.
 
We also purchased positions in the cable industry, based on several positive
developments. Many cable companies are paying down their debt, clustering their
systems, and upgrading the quality and capacity of plants and equipment -- while
adding new services.
 
Despite the expected slowdown in economic growth, the supply of new high yield
bonds is expected to remain robust. With little concern about a recession,
however, we believe that high yield bonds will perform reasonably well in the
near term because of reduced risk of default and increasing demand for high
yield bonds among both retail and institutional investors. For many, investing
in higher quality junk bonds provides an efficient way to increase the yield of
a fixed income portfolio while adding an acceptable level of risk.

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 by or under
the supervision of officers of CBF, CUSG, CFIS, CMBF and CHYF, 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 had
investments in such affiliated issuers at June 30, 1998 as follows:

  (a)  Fund holds 5% or more of that issuer's outstanding shares. During the
       period CSF held 800,000 shares of Abercrombie & Fitch Co. This was more
       than 5% of that issuer's outstanding shares, until May 1998, when
       additional shares were issued. At that point Abercrombie & Fitch Co. was
       no longer considered an affiliate of CSF, since less than 5% of
       outstanding shares were held.
 
  (b)  Fund held an investment under common control. (Note 4)
 
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 $614,553 and are included in net
realized loss from foreign currency transactions. CISF had no outstanding
forward contracts on June 30, 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 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 and
maturities of short-term securities, 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. 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 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.

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 June 30, 1998, 42% of the Fund's debt securities were rated Ba and
58% were rated B by Moody's Investor Services, Inc.
