 .Squirrel Chatter: J.P. Morgan
[PHOTO APPEARS HERE]

        In the history of American finance, there have been many interesting and
important figures from Alexander Hamilton to George Soros. None approaches the
mythic status of John Pierpont Morgan. He dominated the banking scene from the
end of the Civil War to the eve of World War I. Since his death in 1913, no
other person has achieved his level of power and reputation. Morgan was loved by
a few, respected by many, and hated by most. He was not hated for his deeds so
much as what he stood for--massive wealth and power. In the Gilded Age, he
personified the wealth of a Bill Gates and the influence of an Alan Greenspan.
Morgan: American Financier1, a new biography by Jean Strouse, is a splendid
study of the man and his period.
        What a period it was! Some of the people who did business with Morgan
were Mellon, Rockefeller, Harriman, Frick, Carnegie, Baker, Widener and Edison,
a group of tycoons now turned into universities, museums, banks or libraries.
One could ponder on the transformation of a businessman into a building.
        Morgan, as a person, was agreeably complex and contradictory. He was
deeply religious and a womanizer. He was a handsome youth, but an ugly adult
(his nose became deformed by rhinophyma). He was a leader, but not a good
speaker or writer. Despite achieving every worldly success, he suffered from
fits of depression, and often sat alone in his study, smoking a cigar and
playing solitaire. (Strouse does not say what game of solitaire he favored, but
in that primitive age he had to use real cards, not the Microsoft version.)
        Mr. Morgan played solitaire in very nice surroundings. He had a
Manhattan mansion (a series of five, of increasing splendor), an art-filled
house in London, a great country house on the Hudson, and three vacation houses.
He had a fabulous yacht, the Corsair, built in three different versions. His art
collection included Gutenberg bibles and other rare books and manuscripts, old
master paintings, armor, Egyptian antiquities, all in great quantity, many now
in the Met or the Morgan Library. It was the best art collection ever assembled
by one private individual. His artistic taste was informed and refined, but
conventional. For instance, he missed the French Impressionist movement
altogether, although he could have bought a boxcar load of VanGoughs and Monets
for what he paid for one Gainsborough.
        As mutual fund investors, you and I should be most interested in Morgan
as the supreme financial tycoon. His firm put together U.S. Steel, creating the
biggest industrial company in the country. Another deal created International
Harvester. Railroads were the leading industry of his time, and he put together
the Northern Pacific and the Southern Railway. His least successful trust was an
ocean shipping company, IMM, that not only lost money in the freight business,
but through the White Star Line, owned the ill-fated (but photogenic) Titanic.
These mergers were attacked by Progressive "trust-busters," but big companies
were needed as the United States became an industrial giant. Regardless of your
opinion on these mergers, Morgan did many things that clearly benefited the
country.

Bringing in Capital

        The construction of the U.S. railway network was dependent on European
capital. By today's standards, 19th Century America would have been classified
as an Emerging Market. If you think of the United States in Morgan's era as the
equivalent to Argentina now, it's not surprising that many European investors
lost their money on American railroads that went bust. Morgan's firm (Drexel,
Morgan & Co. until 1895, now J.P. Morgan & Co.) was in the center of
international banking, with his father's bank in London funneling money to New
York.2 The amount of European capital invested in the United States grew from
$222 million in 1853 to $3 billion in 1890. Morgan himself spent about half of
each year in Europe, mixing business, art collecting, and spa treatments.3
        The key to keeping European investors happy was a sound dollar, backed
by gold. Therefore, Morgan and the other bankers fought to base the U.S.
currency on a gold standard. Whether your were pro or anti, the gold standard
was one of the key political divides of the 1890s. Farmers always hate bankers,
and opposed the gold standard. So did silver miners, who wanted silver to be
counted in monetary reserves together with gold. The Populist party, which
represented the anti-gold standard factions, wanted faster growth in the money
supply and inflation to enable debtors to pay off their obligations in cheaper
dollars. Morgan, the defender of sound money, was hated as the leader of the
gold-standard Eastern banking interests.

The One-Man Fed

        In 1894, foreign investors became nervous that the Populists would
prevail and inflate the money supply, which would cause their dollar-denominated
bonds to lose value. European investors started selling bonds for gold and
physically shipping the gold to London. At the end of 1894, the U.S. gold
reserve plunged from $100 million to $45 million. In early 1895, gold losses
reached $2 million per day, and the U.S. government faced a crisis not unlike
the one that

                                       2
<PAGE>

forced several Asian countries to devalue their currencies two years ago.
Morgan and several other bankers met with President Cleveland in February 1895,
the day gold reserves dropped to only $9 million, with claims of $12 million
against that gold. A U.S. government default was only a day away. Morgan's group
figured out a way to sell $62 million in new gold-backed bonds without
Congressional approval (the silverites in Congress would not have approved the
bond issue), and saved the government. After the bond sale, Morgan ran a
delicate foreign-exchange support program that succeeded, and U.S. gold reserves
rebounded back over $100 million by June. Despite this triumph, Morgan and
Rothschild, the two syndicate managers, were vilified in the press and in
Congress, where Bryan made a nasty anti-gold, anti-Semitic speech.
        In 1896, the Democrats nominated the Populist William Jennings Bryan for
president. His convention speech was perhaps the best political oration in
American history, ending with the famous phrase: "You shall not crucify mankind
upon a cross of gold." I always had thought that this was a great
anti-materialistic religious thunderbolt, but its context was merely part of
Bryan's violent hatred of the gold standard. Bryan lost the election anyway.

The Panic of 1907

        In 1907, there was a terrible panic, one of the worst financial crises
ever to hit America. Many banks, trust companies, insurance companies, and
stockbrokers had too much debt. After a couple of banks failed, a panic started
that threatened to wipe out a large part of the American financial system and
create the kind of depression that showed up 22 years later in 1929. There was
no Federal Reserve System to regulate banks or act as lender of last resort.
        Morgan and a small group of allies acted as a private Fed, deciding
which financial institutions were hopeless and should be allowed to go under,
and which were sound but illiquid and could be saved by extending new credit.
Morgan then browbeat his friends into extending the savable banks new credit
despite the fear and panic that enveloped Wall Street at that moment. It worked.
The Panic of 1907 was short-lived, and no depression followed.
       A lot of the time Morgan and other nineteenth century bankers were don't-
rock-the-boat conservatives. Sometimes Morgan acted as a risk-taking venture
capitalist. His most successful undertaking was Edison and his new electric
light. In 1878, Edison was well-known, but had little money. Drexel, Morgan
supplied capital for the new Edison Electric Light Co., and continued to support
Edison during the start-up phase. Development was not smooth: the 1878 lamp used
a platinum filament that proved a dead end (Carbon filament worked better, and
finally the tungsten filament bulb, that we still use today, replaced carbon in
turn). The electric light was the "killer app" for the electrical industry. In
1892, Edison's company was combined with its major competition to form General
Electric, with Morgan as the investment banker.
        If Morgan did so many good things in his life, why did he receive such
bad press in his lifetime and to this day? One answer is that his critics on the
left--variously Anarchists, Communists, Fabian Socialists, Utopian Socialists,
other sects of Socialists, union organizers, Populists and
Progressives--detested his immense wealth and unparalleled power. They didn't
believe any one man should be allowed to obtain that kind of wealth and
influence. The standard anti-capitalist caricature is still J.P. Morgan in
formal dress, whether in political cartoon, movie, or the little banker guy in
your Monopoly game. No one since Morgan has equaled his immense power. Morgan's
power died with him. Our world today has grown too large for any one financier
to dominate it.

Acorn Twenty
       .In a Nutshell

[PHOTO APPEARS HERE]

     This quarter paid off for small- and mid-cap investors. Acorn Twenty gained
13.6% for the quarter ended June 30, 6.5% ahead of the S&P 500, but just
slightly behind the 14.2% return of the S&P MidCap 400 Index.

     Investors rediscovered value during the second quarter. They finally
noticed the wide valuation gap between small- and mid-cap stocks versus their
large-cap brethren.

The small-cap Russell 2000 and the S&P MidCap 400 indexes outperformed the S&P
500 by 8.5% and 7.1%, respectively, during the quarter.

This supports our belief that relative value exists among small to midsized
companies. Many of Acorn Twenty's stocks trade at lower price-earnings multiples
than S&P 500 companies, yet have higher expected growth rates.

     Twelve stocks posted double-digit gains in your Fund. Some standouts
include AES, an energy company, up 56% during the quarter. Liberty Media was up
40% following its investment in News Corp. Several other stocks were up 20% or
more, including three stocks highlighted in our March 30 report--Telephone &
Data Systems, RCN, and Jones Apparel.

     We had one disappointment this quarter, McKesson HBOC, a hospital computer
services company. The stock declined 42% during the quarter when an accounting
scandal was uncovered in April. While we are disappointed, it is important to
remember that our concentrated strategy is to have our winners outweigh the
losers, resulting in superior, long-term return potential.

     We continue to be excited about the Fund's future prospects and we
appreciate your investment in Acorn Twenty.

     Keeping Up
               with Jones
     Jones Apparel Group (JNY) has been in Acorn Twenty since the Fund's
inception. Jones manufactures apparel, primarily for women, and owns well-
regarded brand names. In addition to the Jones New York and Evan Picone labels,
Jones makes the Lauren by Ralph Lauren line of clothes as well as Polo Jeans,
both under license from Ralph Lauren. The Jones management team is impressive.
The company has posted 20% or greater sales and earnings growth every year since
its 1991 IPO, even though the industry is notorious for its fickle fashion fads.
     This year, Jones announced it was acquiring shoe manufacturer/retailer Nine
West. Wall Street was initially thumbs (or toes) down on the deal since Nine
West had been a troubled, mismanaged company. But where investors turned up
their noses, Jones saw opportunity. Poor performing Nine West stores will be
closed. As a result, we estimate as much as $100 million in working capital
could be redeployed by tighter inventory management. Wall Street had put its
foot in its mouth. After seeing the acquisition's potential opportunities and
return, Jones' stock price climbed, up 56% for the year at June 30, 1999. The
acquisition closed on June 15, 1999, and we expect Jones' new "sole-mate" to add
significantly to earnings and cash flow.

This graph compares the results of $10,000 invested in Acorn Twenty on November
23, 1998 (the date Fund shares were first offered to the public), with all
dividends and capital gains reinvested to the S&P MidCap 400.
     The S&P MidCap 400 is a market value-weighted index of 400 stocks that
are in the next tier down from the S&P 500. The S&P 500 is a broad
market-weighted average of U.S. blue-chip companies. The Russell 2000 is formed
by taking the 3,000 largest U.S. companies and then eliminating the largest
1,000, leaving a market capitalization-weighted Index of 2,000 small companies.
All indexes are unmanaged and returns include reinvested dividends.
     Past performance does not guarantee future results. The investment return
and principle value of an Investment In the Fund will fluctuate so that Fund
shares, when redeemed, may be worth more or less than their original cost.

Acorn Foreign Forty
    .In a Nutshell

[PHOTO APPEARS HERE]
     Since inception, the Fund has returned 31%, more than triple the returns of
its benchmark indexes.

     Acorn Foreign Forty returned a satisfying 9.4% in the second quarter, well
ahead of the 4.8% return of the creatively named Salomon Smith Barney Cap Range
$2-10 Billion Index. Since inception, the Fund has returned 31%, more than
triple the returns of its benchmark indexes.
     Three of your Fund's stocks gained more than 50% during the quarter. We
highlighted Softbank last quarter when it was our 10th largest holding. It is
now our largest position. We once again thank Michael King, our Japanese
analyst, for unearthing Softbank at a time when it was very underfollowed.
Michael also scored with Nintendo (up 64%--see inset), a name that is on the tip
of every child's tongue, but not yet in every parent's portfolio. Our
international research director, Roger Edgley, contributed contract manufacturer
Natsteel Electronics in Singapore, up 56%.
     Not all of our stocks went up. We experienced modest declines in two of our
European life insurance companies, Mapfre Vida in Spain, and ASR in the
Netherlands. We visited these companies recently and have confirmed that their
core life insurance businesses are still doing extremely well. Danish cleaning
contractor ISS and Olivetti, an Italian typewriter-maker-turned-telecom-
operator, also had poor stock returns this quarter although nothing bad happened
to their businesses.
     We continue to see many excellent opportunities in the international mid-
to large-cap stock universe. We believe Acorn Foreign Forty provides both a good
way to diversify your portfolio and to own what we predict will be tomorrow's
blue chips.

     Move Over
             Mickey
     Most six to twelve year olds today enjoy Coca-Cola, McDonald's, Disney, and
Nintendo. Ranked by hours used, the winner is Nintendo. Unique products plus a
strong, global brand equals high barriers to entry, high margins, and a mountain
of cash to fund future growth. This is a classic case where the company is well-
known, but the stock is not. We think this will change as Nintendo, a leader in
the expanding industry of interactive entertainment, advances to the next level
in the great stock market game (and becomes a blue chip on everyone's buy list).

Acorn USA
     .In a Nutshell

     Small stocks rallied during the second quarter. The small-cap Russell 2000
Index rose 15.6%, more than double the 7.1% return of the S&P 500. Acorn USA
outpaced both indexes, gaining 17.5%.
     At the start of the first quarter, the market was persecuting whole groups
of stocks. Value stocks were thought to be the ugly stepsisters of the growth-
stock beauties. Cyclical stocks were given up for dead after the Asian economies
crumbled. Small-cap stocks were on the wrong side of the market's large-cap
bias. The only bull-market participants were the darling fat-caps and Internet
companies.
     Everything changed in April after interest rates increased. That's usually
bad for all stocks, but it is particularly troublesome for stocks trading on
hyped future earnings. As rates rose, price became more important than future
promises. Undervalued stocks soared (even the historically rate-sensitive
utility stocks rallied), while high-priced glamour stocks declined. Many
investors were surprised to discover that Internet stocks could be derailed
(temporarily) by something as old-fashioned as an interest rate hike.
     Acorn USA's best stocks of the quarter were not so long ago its worst. All
are thriving small companies whose stock prices had plunged, then rebounded 50%
or more by June. Some examples include Magellan (managed care), Aspect Telecom
(call center software) and Equitable Resources (gas utility).
     Small stocks finally were the market's big winners. How long will this
small-cap rally continue? Well, small stocks underperformed large stocks for
five years. We can hope that the market will shift to favor small caps over the
next five years. Acorn USA shareholders should do well if this normal market
rotation occurs.

     Just What the
            Patient Ordered
National Data knows two truths:

1) People prefer plastic to paper. Money, that is. Ten years ago, only 15% of
all consumer payments were made via credit cards. Today it's 25% and growing.
Processors like National Data make their money routing credit card and other
electronic payments between merchants and banks.

2) For all the miracles of modern medicine, the health care payment system is
strictly Stone Age. You can get your kidney stones removed in one hour, but your
insurance claim likely won't get paid for five months. National Data is helping
solve the problem by automating the whole health-claims process.

Small stocks rallied during the second quarter. The small-cap Russell 2000 Index
rose 15.6%, more than double the 7.1% return of the S&P 500.

     This graph compares the results of $10,000 invested in Acorn USA on
September 4, 1996, (the date Fund shares were first offered to the public), with
all dividends and capital gains reinvested, to the Russell 2000 Index.
     The Russell 2000 is formed by taking the 3,000 largest U.S. companies and
then eliminating the largest 1,000, leaving a market capitalization-weighted
index of 2,000 small companies. The Lipper Small-Cap Funds Average, which
includes Acorn USA, is an average of all U.S. small-cap funds tracked by Lipper,
which consisted of 789, 777 and 698 funds for the second quarter, 6- and 12-
month periods above. The S&P MidCap 400 is a market value-weighted index of 400
stocks that are in the next tier down from the S&P 500. The S&P 500 is a broad
market-weighted average of U.S. blue-chip companies. All indexes are unmanaged
and returns include reinvested dividends.
     Past performance does not guarantee future results. The investment return
and principal value of an investment in the Fund will fluctuate so that Fund
shares, when redeemed, may be worth more or less than their original cost.

Acorn International
       .In a Nutshell

[PHOTO APPEARS HERE]

These results are no flash-in-the-pan. Whether you look at the last twelve
months or the trailing five years, your Fund's performance numbers rank in the
top-quintile of all international equity funds followed by Lipper.

Your Fund is flying. Acorn International was up 15.5% in the second quarter.
This is 9.3% better than the EMI Index and 9.9% above the Lipper International
Funds Index, and nearly 2% ahead of the Lipper International Small Cap Funds
Index for the three months. It even beats the S&P 500 by 8.4% (diversification
finally pays!). These results are no flash-in-the-pan. Whether you look at the
last twelve months or the trailing five years, your Fund's performance numbers
rank in the top-quintile of all international equity funds followed by Lipper.
For the one- and five-year periods ended June 30, 1999, the Fund ranked 84 out
of 638 funds and 35 out of 200 funds, respectively./1/

    Contractors for
                       Hire
Electronics companies love to design and market products. Making them is more of
a challenge in today's world. Many of the best brand names outsource the
manufacturing function to specialist contractors known as EMS (electronic
manufacturing services) companies. Two of our Singapore EMS holdings, Venture
Manufacturing and Natsteel Electronics, work for Hewlett Packard, Apple, Sony,
Cisco and others, making items such as computers, servers and disk drives. Both
sides win. The customer lowers production costs and frees up capital, while the
EMS provider earns a high return by running its facilities efficiently. No
wonder these stocks are growing earnings yearly in excess of 25%.

     How did we do it? The short answer, this quarter, is Singapore. The local
Straits Times Index had a fabulous run, up 46% in U.S. dollars since the end of
March. Our five stock picks in that market did even better, rising a stellar 93%
over the same period. Best of all, they were BIG holdings, generating a combined
$93 million in profits for shareholders in three months. Credit goes to Roger
Edgley, our director of International Research and Asian equity specialist, who
identified Singapore as the place to hide during the regional meltdown.
Secondary credit goes to that old-fashioned virtue, patience. We first bought
Star Cruises in the summer of 1993 and Venture Manufacturing in the spring of
1995. We added to both positions at the depths of the crisis, between June and
September of last year, at prices in excess of 75% below where the stocks sell
today. Datacraft Asia and Natsteel Electronics are newer positions, initially
appearing in the portfolio around 18 months ago. What all these stocks have in
common is: (1) Roger identified them all as quality companies with top-flight
management; and (2) we put fresh money into them when they were deeply out of
favor. That defines long-term investing to us.

     We wrote in the last quarterly report that the outlook for foreign
investing was improving. Small-cap stocks are leading the charge, after two
years of lagging their large-cap peers by double digits. According to the
Salomon Smith Barney indexes, equities outside the United States with market
capitalizations below $1 billion are up 14.7% year-to-date versus a gain of 4.7%
for those with market capitalizations above $5 billion. Patience wins again.

/1/  This ranking represents a combination of the Lipper International Small Cap
Funds category and the Lipper International Funds category for the 1- and 5-year
periods ended June 30. The two categories were combined to show how Acorn
International performed among the broadest universe of international funds. The
ranking was calculated by Wanger Asset Management, L.P., Acorn International's
investment adviser, assigning a rank to the average annual total return of each
fund in the International Small Cap Funds and International Funds categories, on
a combined basis (the best-performing fund received a rank of 1 and the worst
received a rank of 638, or 200, respectively, for the 1- and 5-year periods).
The percentile rank was calculated by dividing Acorn International's 1- and
5-year rank (84 and 35, respectively) by the total number of funds for the 1-
and 5-year periods (638 and 200, respectively). This produced a rank of 13.2%
and 17.5%, respectively, for Acorn International, placing it in the combined
categories top quintile.

Acorn Fund
        .In a Nutshell


[PICTURE APPEARS HERE]

It finally happened--small stocks outperformed blue-chip stocks in the second
quarter. Acorn Fund was up 15.8% for the quarter, double the return of the S&P
500, and slightly ahead of the small-cap Russell 2000 Index.

        We had been complaining about small caps underperforming large caps.
While we were whining, we were actively swapping some of our winners that had
become mid-caps, into small caps, which were better values. We bought about $300
million of small stocks in the second quarter.

        Most of our largest-percentage winners in the quarter were stocks with
cap sizes under $1 billion. Magellan Health, a managed-care company, jumped a
robust 137%, while Gadzooks, a retail speciality store for young adults,
surprised us by more than doubling. Electronics distributors Kent Electronics
and Pioneer Standard rose 99% and 84%, respectively. AirNet Systems soared 93%.
Employee timeclock company Kronos clocked an 86% move.

        Fears about Asia subsided in the quarter. Singapore-based Star Cruises
sailed to a 145% gain and Natsteel Electronics zapped a 61% return. Independent
power producer AES, which had dropped due to fears about Asian contracts,
provided an electrifying 56% rise.

        Our Internet-related stocks were hot. Softbank, a Japanese-based company
featured in our 1998 annual report, netted an 80% return, while information
provider InfoUSA doubled.

        We are continuing to find and buy great small-cap companies and we
believe these companies have the potential to deliver long-term rewards.


     A Towering
                Landlord

We like companies that benefit from the declining costs of electronics. For
example, Acorn Fund was an early owner of cellular telephone companies at a time
when cell phone prices plunged as much as 90%. A play on this theme is the
recently purchased Pinnacle Holdings that controls valuable real estate in the
form of broadcasting towers. Competition to provide wireless phone service in
urban areas is robust. Since all cellular phone companies need towers to
broadcast their signals to provide service, and since zoning restricts new tower
construction, Pinnacle Holdings stands to benefit as more competitors build
wireless systems. Its stock rose 62% last quarter.

Acorn Fund was up 15.8% for the quarter, double the return of the S&P 500, and
slightly ahead of the small-cap Russell 2000 Index.

This graph compares the results of $10,000 invested in Acorn Fund on June 10,
1970 (the date Fund shares were first offered to the public), with the S&P 500
Stock Index with dividends reinvested.

        The S&P 500 is a broad market-weighted average of U.S. blue-chip
companies. The Russell 2000 is formed by taking the 3,000 largest U.S. companies
and then eliminating the largest 1,000, leaving a market capitalization-weighted
index of 2,000 small companies. The Lipper Small Cap Funds Index, which includes
Acorn Fund, measures the performance of the 30 largest U.S. small-cap funds
tracked by Lipper. The S&P MidCap 400 is a market value-weighted index of 400
stocks that are in the next tier down from the S&P 500. All indexes are
unmanaged and returns include reinvested dividends.

        Past performance does not guarantee future results. The investment
return and principal value of an investment in the Fund will fluctuate so that
Fund shares, when redeemed, may be worth more or less than their original cost.

(a) In accordance with a requirement by the Securities and Exchange Commission,
the Acorn USA ratio reflects total expenses prior to the reduction of custodian
fees for cash balances it maintains with the custodian ("custodian fees paid
indirectly"). This ratio net of custodian fees paid indirectly would have been
1.79% for the period ended December 31, 1996.

(b) Net investment income (loss) per share was based upon the average shares
outstanding during each period.

Acorn Family of Funds
      .Notes to Financial Statements (unaudited)


1.  Nature of Operations

Acorn Fund, Acorn International, Acorn USA, Acorn Twenty and Acorn Foreign Forty
(the "Funds") are series of Acorn Investment Trust (the "Trust"), an open-end
management investment company organized as a Massachusetts business trust. The
investment objective of each Fund is to seek long-term growth of capital.

2.  Significant Accounting Policies
      .Security valuation

Investments are stated at current value. Securities traded on securities
exchanges or in over-the-counter markets in which transaction prices are
reported are valued at the last sales price at the time of valuation. Securities
for which there are no reported sales on the valuation date are valued at the
mean of the latest bid and ask quotation or, if there is no ask quotation, at
the most recent bid quotation. Money market instruments having a maturity of 60
days or less from the valuation date are valued on an amortized cost basis.
Securities for which quotations are not available and any other assets are
valued at a fair value as determined in good faith by the Board of Trustees.

      .Foreign currency translations

Values of investments denominated in foreign currencies are converted into U.S.
dollars using the spot market rate of exchange at the time of valuation.
Purchases and sales of investments and dividend and interest income are
translated into U.S. dollars using the spot market rate of exchange prevailing
on the respective dates of such transactions. The gain or loss resulting from
changes in foreign exchange rates is included with net realized and unrealized
gain or loss from investments, as appropriate.

      .Security transactions and investment income

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed) and dividend income is recorded on the ex-dividend date,
except that certain dividends from foreign securities are recorded as soon as
the information is available to the Funds. Interest income is recorded on the
accrual basis and includes amortization of discounts on money market instruments
and long-term debt instruments when required for federal income tax purposes.
Realized gains and losses from security transactions are reported on an
identified cost basis.

      .Use of estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results may differ from those estimates.

      .Financial instruments

Each Fund may purchase or sell exchange-traded financial futures contracts,
which are contracts that obligate that Fund to make or take delivery of a
financial instrument or the cash value of a securities index at a specified
future date at a specified price. The Funds enter into such contracts to hedge a
portion of their portfolio. Gains and losses are reflected as "Net Realized Gain
(Loss) on Futures" in the Statements of Operations. Additionally, each Fund may
engage in portfolio hedging with respect to changes in currency exchange rates
by entering into forward foreign currency contracts to purchase or sell foreign
currencies. The Statements of Operations reflect gains and losses as realized
for closed forward foreign currency contracts and unrealized for open contracts.
A Fund bears the market risk that arises from changes in the value of financial
instruments and securities indices (futures contracts) or from changes in
foreign currency rates (forward foreign currency contracts) and the credit risk
should a counterparty fail to perform under such contracts.

      None of the funds had futures contracts open at June 30, 1999. Acorn Fund
and Acorn International entered into forward contracts to sell foreign currency,
as described below:

       .Fund share valuation

Fund shares are sold and redeemed on a continuing basis at net asset value. Net
asset value per share is determined daily as of the close of trading on the New
York Stock Exchange on each day the Exchange is open for trading by dividing the
total value of each Fund's investments and other assets, less liabilities, by
the respective number of Fund shares outstanding.

       .Federal income taxes, dividends and distributions to shareholders

Each Fund has complied with the special provisions of the Internal Revenue Code
available to investment companies.

       Acorn Fund, Acorn International and Acorn Foreign Forty have elected to
mark-to-market their investments in Passive Foreign Investment Companies
("PFICs") for Federal income tax purposes. A summary of transactions relating to
PFICs for Acorn International is as follows:
