>Squirrel Chatter: From Chain Mail To E-Mail

                       A Five-Minute History of the World


[PHOTO HERE]

During the early part of the last millennium, the hotbed of ideas that moved
civilization forward came from the Steppes of Asia, not the Valley of Silicon.
The Western Hemisphere wasn't even on the map at that point, and Europe was an
insignificant, rather primitive gang of quarreling principalities at the wrong
end of the Eurasian landmass.

    The center of power, and the center of civilization, was ruled by Genghis
Khan and his children. He and his unstoppable armies created a gigantic empire
that spread across Mongolia and China, and included Persia and Russia. Nobody in
Europe knew the extent or power of the Mongol Empire until young Marco Polo
traveled across Asia in the 1280s. Years later, he returned to his native Venice
with a sack of jewels and a pack of tall tales about lands of gigantic, rich
cities, an opulent and sophisticated court, and advanced technology. Most of his
contemporaries thought he was kidding. Here are two examples of Marco's stories
that sounded crazy in 1290, but after a few centuries, changed the world.

Rocks That Burned
Marco Polo wrote:

          It is a fact that all over the country of Cathay there is a kind of
     black stone existing in beds in the mountains, which they dig out and burn
     like firewood. If you supply the fire with them at night, and see that they
     are well kindled, you will find them still alight in the morning; and they
     make such capital fuel that no other is used throughout the country. It is
     true that they have plenty of wood also, but they do not burn it, because
     those stones burn better and cost less./1/

     Modern technology is based on burning rocks. The story of the Industrial
Revolution is how our lives changed when we learned how to burn coal to run
ships and trains, and make electricity for motors and computers. Adopting oil
and gas was also part of the story. As The Economist put it, "Coal was to power
Britain's industrial revolution, and, later, as steam-powered machinery spread,
the first steps in its agricultural revolution too.

     ... Today's oil-driven world and tomorrow's driven by who knows what owe
their birth to coal."/2/

Money That Grows On Trees

     In Medieval Europe, coins made of gold and silver were scarce and often of
questionable quality. Marco Polo reported how Kublai Khan turned tree bark into
money:

          The Emperor's Mint then is in this same City of Cambaluc [Beijing
     today], and the way it is wrought is such that you might say he hath the
     Secret of Alchemy in perfection, and you would be right! For he makes his
     money after this fashion.

          He makes them take the bark of a certain tree, in fact the Mulberry
     Tree, the leaves of which are the food of the silkworms, -- these trees
     being so numerous that whole districts are full of them. ...

          ... All these pieces of paper are issued with as much solemnity and
     authority as if they were of pure gold or silver.

          And the Khan causes every year to be made such a vast quantity of this
     money, which costs him nothing, that it must equal in amount all the
     treasure of the world./3/

     That's right folks, the Chinese invented the Fed. China's first version of
paper money appeared in 1024. In contrast, 13th century European governments
were weak, with poor communications, primitive legal systems, and no fiscal
policy above the level of extortion. Europe's first attempt at paper money came
400 years later when Johan Palmstruch founded the Stockholm Banco in 1656. His
was a private company that intended to issue paper money, enjoying royal
privileges in return for a royal cut. After sustained lobbying and a public-
relations effort that would be impressive today, an issue of bank notes followed
in 1661. But the venture over-reached itself, issued too many notes and crashed
disastrously in 1667. Palmstruch was disgraced and -- fickle government -- was
sentenced to death./4/

     Paper money has had a mixed career since, with a number of disastrous
hyper-inflationary episodes. The test of a modern government's strength and
sense is, like Kublai Khan's, the ability to issue credible paper money. "Strong
government" has been another central theme of the last two centuries, with both
beneficial and destructive results.

     History from Marco Polo to Alan Greenspan mainly explains how the language
of the Internet turned out to be English instead of Turkish, Chinese, or
Arabic./5/ Marco Polo was a 13th century primitive visiting a superior
civilization. Five hundred years later, the tides reversed. Europe adopted coal,
paper money, printing, gunpowder and the magnetic compass from China, and went
on to

                                       2
<PAGE>

build technology, wealth and power. China preferred stability and stagnation.
Europe had taken control of the world by the end of the 19th century.

  History hasn't ended yet. The European empires dissolved in the 20th century.
Asia, no longer stagnant, now has many countries that fully match Western wealth
and technology.

  Is there a message here for investors?  We already know that everything
changes with time.  Venice, Constantinople, and Cordoba now exist as outdoor
museums where tourists come to admire their 13th century glory.  England was a
minor province for some French kings then; no one in the 13th century would have
put the English on a world power list.  In the same way, stocks have had their
times of leadership followed by stagnation or extinction.  One hundred years
ago, the best stock in the United States was the Pennsylvania Railroad.  Later
favorites would include GM, U.S. Steel, RCA, Sears, DuPont, Schlumberger, and
IBM, all of which are still around but not what they once were.  A few have had
longevity: GE, Merck.

  Will current favorites fade?  Wal-Mart without Sam and Microsoft without billg
might well. Many of the new Internet companies will suffer the biggest massacre
of naifs since the Children's Crusade. Will new companies become favorites? Of
course. We will try to find some of them. Our small-company, global approach
ought to keep working. The next seven hundred years look very promising.

1999 Scarlet A Winners

     I must tell you what the Great Khan did in regard to those barons who had
  behaved well in the battle. Him who was before captain of 100, he made captain
  of 1000. ... Besides that, he bestowed upon them fine jewels of gold and
  silver, and pearls, and precious stones; insomuch as the amount that fell to
  each of them was something astonishing./6/

  Every year, we reward the stock market barons whose ideas won the investment
battle. While we can't bestow jewels and great armies to each of them, we do
bestow this recognition, our gratitude and a Scarlet A certificate. To be
considered for 1999, the recommended stock had to increase more than 140% and
make a profit exceeding $12 million.

  Three big winners came from Japan. Softbank, an Internet service provider and
investment company, had a weighted return of 1,493% for Acorn Foreign Forty and
was a big winner for Acorn Fund too. Trans Cosmos, an information technology
services company, gained 1,257% for Acorn International. JAFCO, a venture
capital fund, returned more than 600% and was another Acorn International
winner. Our gratitude goes to Mahendra Singh Negi of Merrill Lynch Japan for
these picks. Mahendra has the distinction of being the first Scarlet A hat-trick
winner.

  Other international winners included NTL, a cable television operator in the
UK, up more than 175% for Acorn Fund and Acorn Foreign Forty. Ron Getto of
Donaldson Lufkin & Jenrette receives the Scarlet A for this pick for a second
year.  Star Cruises, a Singapore-based cruise line, was brought to us by Lim Kok
Ann of BNP Prime Peregrine in Singapore. Star Cruises saw a 385% gain for Acorn
Fund and Acorn International.

  Closer to home, two biotechnology companies topped the Acorn Fund list.
CuraGen returned 885%. Our thanks to Richard van den Broek of Chase H&Q for that
suggestion. David Stone brought Myriad Genetics to our attention, up 390%.
David, formerly with SG Cowen, is now consulting with his own firm, Liberty Tree
Advisors.

  Getty Images, up 183% in Acorn Fund, is a stock photography company. Bob East
of Deutsche Bank Alex Brown gets the Scarlet A nod for this pick. And finally,
Barry Ollman of Hanifen Imhoff brought UnitedGlobalCom, a manager of foreign
cable television stations, to our attention. This stock gained 638% for Acorn
International and nearly 200% for Acorn Fund.

  Thanks for sharing your inspirations. I'm sure our shareholders thank you too.
We look forward to hearing your future picks and to seeing what the market has
in store for all of us in 2000.

Acorn Twenty
    >In a Nutshell

[PHOTO HERE]

Acorn Twenty finished its first full year of operation up 29.3%, strongly
outperforming the 14.7% S&P MidCap 400 return and the S&P 500's 21.0% gain for
the year. At year-end, Acorn Twenty had $68.5 million in assets. Looking back on
our inaugural year, we want to thank our shareholders for the integral role you
played in our strong beginning.

  Several stocks contributed to Acorn Twenty's 1999 performance. The biggest
winners were our telecommunications stocks. Telephone and Data Systems, a
cellular phone and personal communication services provider, was up 183% for the
year following the company's announcement of the sale of its Aerial
Communications subsidiary to Voicestream Wireless. RCN, a competitive local
exchange carrier (CLEC), rose 175% as investors (including Paul Allen, co-
founder of Microsoft and owner of the Portland Trail Blazers) realized the value
of its residential local phone, cable, and data networks. Another
telecommunications stock, McLeod USA, gained 62.6% for the Fund. McLeod, like
RCN, is a CLEC, but provides services to businesses rather than residential
communities. Other strong performing stocks include Liberty Media, a long-time
Acorn Fund favorite, up 147% for the year, and AES Corp, an independent power
producer, up 90%.

  Losers came from the insurance industry, a tough area for investors despite
low valuations. UICI, an insurance and specialty finance company, and
Progressive, an auto insurer, both had disappointing years. We felt a recovery
in this sector was imminent but we now believe there are better opportunities
elsewhere.

  Acorn Twenty celebrated its one-year anniversary on November 23, 1999. Its
success is due to the collaborative efforts of the Acorn research team. Our
sincere thanks go to Ralph Wanger, Chuck McQuaid, Rob Mohn, Laura McKenna, Jason
Selch, and Ben Andrews.

                                   Everyone!

AES contributed a whopping 90% to Acorn Twenty last year -- high-voltage
performance from a long-time Acorn Fund favorite.  AES owns and operates power
plants and electric utilities in 16 countries including the United States,
Brazil, Pakistan, Australia, India, Hungary, China and the United Kingdom.
Founded in 1981, AES started with a simple vision of delivering low-cost
electricity to U.S. utilities that were short of power.  Soon, AES realized that
there were many opportunities outside the United States to build or acquire
utility assets from governments looking to privatize/deregulate their power
industries. Today, AES is the preeminent, independent global power company with
a history of 30% annual earnings gains. We believe the recent $3 billion
acquisition of Drax Power in the United Kingdom could keep AES growing brightly
for years to come.

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 Lipper Mid Cap Fund Average, which
includes Acorn Twenty, measures the performance of all U.S. mid-cap funds
tracked by Lipper. 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
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 Foreign Forty
    >In a Nutshell

[PHOTO HERE]

At the end of 1999, Acorn Foreign Forty was up 81.6% for the year, more than
double the returns of the Salomon Smith Barney Cap Range $2-10 Billion Index
(+23.5%), the EAFE (+ 27.0%) and the Lipper International Funds Average
(+40.8%). We are pleased with our strong beginning and we hope that you are too.

  Much of Acorn Foreign Forty's gain for the year came in the fourth quarter as
the Fund advanced 46.7% on the strength of our information technology (IT)
stocks. There was no slowing of the Fund's largest position, Softbank, up 151.5%
for the quarter and a staggering 1,493% for the year. This Japanese Internet
company was an obvious winner for the portfolio. Finland's Comptel, a producer
of telephone-billing software, was up 273% in 1999 and was also among the Fund's
top performers. Benefiting from Internet-related services, two Italian
publishing names -- Editoriale L'Espresso (+375.9) and SEAT Pagine Gialle
(+211%) -- posted strong annual gains.

  On the downside, Mapfre Vida, a Spanish life insurance company, fell out of
favor with investors. We view this as a solid business with strong prospects, a
stance that its parent company seems to agree with. As of the writing of this
report, the parent has announced plans to buy out minority shareholders at a
premium price.

  Looking forward, we believe we are well positioned in areas where mid-caps
have the right balance of scale, financial strength, and entrepreneurial spirit,
to be leaders. These industry groups include emerging telecommunication
services, IT services, outsourcing services and media. In addition, the
valuation gap between large- and mid-cap stocks is working in our favor,
allowing us to pick up high-quality names at good prices.

Internet Advertising Is
                                 Music For M6

Ever wonder what those Internet IPO's do with their newly minted millions? M6
Metropole TV in France can tell you. They advertise. Most Internet start-ups
have only two assets: a business plan and a brand name that is built using
advertising, and lots of it. M6 is the fastest growing TV station in France and,
with a format similar to MTV, appeals to the tech-savvy generation these start-
ups are anxious to reach. In addition, previously regulated European companies
focusing on branding for the first time, are turning to television advertising,
putting even more money in M6 coffers.

Acorn USA
    >In a Nutshell

[PHOTO HERE]

Your Fund outperformed the stock market indexes both large and small in 1999.
Acorn USA returned 23.0% last year, beating the small-cap Russell 2000's 21.3%
and the large-cap S&P 500's 21.0% return. Most of our performance came in the
final quarter of the year, when Acorn USA gained 18.9%, the Russell 2000 gained
18.4%, and the S&P 500 was up 14.9%.

  Technology and telephones were our biggest winners. Tech stocks roared all
year, ending 1999 with a deafening crescendo. Our top holding, Micros Systems (a
management systems company for restaurants and hotels), more than doubled in
price to become the largest position in the Fund. Aspect, a call-center
technology provider, was another tech winner.

  Internet stocks continued to climb as concept stocks, ignoring fusty ideas
such as profitability. Our Internet plays included RCN (rcn.com), up 170%, TV
Guide (TV web portal), up 265%, and Project Software (mro.com), up 170%. Some
Internet magic also rubbed off on our wireless telephone stocks (Telephone and
Data Systems and Price Communications), as investors realized cellular phones
would be the newest way to surf the Web.

  Our insurance stocks were disappointing. Our two worst-performing stocks were
UICI and Acceptance Insurance, both caught with their reserves down in the
fourth quarter. Both stocks overshot to the downside and currently trade at
prices that we believe offer favorable risk/reward tradeoffs.

  The investing world has recently fixated on growth vs. value stocks,
forgetting the small-cap, large-cap feud.  We are pleased that small caps have
been outperforming large caps since last April. We are optimistic that small
caps will continue their good showing in the year 2000. After all, why do you
think they call the small-cap index the Russell 2000?

                                    Rebirth

Aspect Communications sells telephone call center technology.  Aspect's stock
declined last January after announcing poor sales of its call center
software/hardware systems.  Rather than hoping the business would correct itself
with some relatively minor tweaking (the usual business reflex when faced with
crisis), management opted for a dramatic gesture. They slashed their hardware
switch business from 60% to 30% of their revenue base and emerged as a software
company. Our technology analyst, Todd Narter, assessed the quality of Aspect's
new products (high) and new management team (higher) and advocated holding the
stock. Good decision. Aspect has increased six-fold since, as demand for its new
software exploded.

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 and consisted
of 820 funds for the fourth quarter and 757 funds for the 12-month period. 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]

The champagne corks popped on New Year's Eve across the world without a Y2K
crisis, and global equities celebrated the turn of the millennium with a
powerful rally. Acorn International fully participated in the festivities. For
1999 as a whole, Acorn International soared 79%, beating all of its relevant
benchmarks. The Fund rose 42% over the three months ended December 31, as
compared to 9% for the EMI Index, 17% for EAFE, and 28% for the peer group.
These results remind us, once again, that market timing is a difficult game.
Investors who stayed on the sidelines in the fourth quarter to be `safe' paid
dearly for their insurance, while those who followed a strategy of being
invested for the long-term were handsomely rewarded for their discipline.


A year ago we predicted that the environment for international investing was
on the upswing. Today, our opinion is in the direction of greater positive
conviction.


  To generate big returns you need big winners. Our star performer of the year
was Star Cruises, which rose 385% for a gain of $77 million. In terms of themes
that worked well, Celestica (+352%) and Venture Manufacturing (+201%) earned
shareholders $108 million on the growth in outsourced production of electronic
goods, while NTL (+176%) and UnitedGlobalCom (+638%) together made us $71
million on the premise that the European cable industry would consolidate. We
had few pure Internet plays. Rather, our stocks are considered Internet
beneficiaries. They include Editoriale L'Espresso (+369% =$58 million),
Datacraft Asia (+369%=$57 million), JAFCO (+600%=$46 million) and Trans Cosmos
(+1257%=$40 million). Of our long-term core holdings, Hong Kong trading firm Li
& Fung gained 150% to post $45 million in profits, while newcomers Baltimore
Technologies and ERG rose 575% and 293% respectively, to earn shareholders $67
million combined. By comparison, the most lost by any one stock in the portfolio
in the last twelve months was $5.8 million.

  Although we do not pay a lot of attention to country weightings in managing
the Fund, being in Asia did matter in 1999. We made $250 million in Japan and
$212 million in Singapore, on holdings that appreciated around 265% each. Italy
was our best European market, with a $120 million gain, followed by Sweden at
$66 million and France at $62 million (along with Canada and Hong Kong). Only
Spain, Denmark and Peru finished the year in the red, albeit in single digits.

A year ago we predicted that the environment for international investing was
on the upswing. Today, our opinion is in the direction of greater positive
conviction. Without making any predictions, we remain steadfast optimists.

  From the entire international team to all of you, Happy New Year!

                                   A Star Is
                                     Born

Few investors have heard of Star Cruises. That's because its owner, the Lim
family, holds most of the shares. But the Singapore-based company is already
Asia's largest cruise ship operator. After the pending takeover of Norwegian
Cruise Lines, it will have a fleet of 23 vessels and rank third in the world,
behind Carnival and Royal Caribbean. Asia's cruise market is projected to grow
25% this year to one million passengers. Star intends to develop the market
further by offering service to and from Japan beginning in March. Given that
under one percent of Japanese tourists go on cruises each year, we believe that
the company's growth prospects are nothing short of stellar.

Acorn Fund
    >In a Nutshell

[PHOTO HERE]

1999 was an excellent year for the Acorn Fund. We no longer had to swim
upstream--small-cap stocks matched large caps, ending four years of relative
underperformance. Our foreign stocks jumped 139%! Acorn Fund rose 33.4% in the
year and 21.9% in the quarter, outpacing the unmanaged small-cap and large-cap
indexes for both time periods.

  Acorn's biggest winner for the year -- and likely for all time -- was
Softbank, a Japanese stock. This Internet company was up nearly fifteen-fold for
the year and is now the Fund's largest position. Not only did the stock soar, we
called the shot, featuring it a year ago in the 1998 Annual Report. Our other
blockbuster foreign stock was Star Cruises, up 385% for the period.

  Telecommuncations was our best sector during the year. Cable and telephone
providers NTL and UnitedGlobalCom in Europe, plus RCN in the United States, each
wired home gains over 170%. Telephone and Data Systems, a cellular and land-line
phone company, jumped 180%.

  Media stocks continued their star performances. Our stalwart, long-term
holding Liberty Media jumped nearly 150% while TV Guide doubled. We swapped out
of much of Liberty as we found better values in smaller names. We sold our
remaining TV Guide after it ran up following the announcement of merger plans
with Gemstar.

  We made good money in a number of technology stocks. Contract manufacturer
Solectron assembled a 104% profit, while connector and laser firm Oak Industries
tripled on a sellout to Corning. Electronic time-clock company Kronos clocked a
double while hospitality computer systems company Micros Systems served up a
125% gain.

  We believe Acorn Fund has delivered excellent returns this year although we
underweighted the highly speculative technology stocks that are currently the
rage. As stock-pickers--not stock-traders--we buy names that we believe have the
potential to perform for the long-term, avoiding the risk and over-valuations
that often come with buying the "flavor of the month."

                              We got the Picture

We remain biased toward companies that benefit from technology. Getty Images
licenses rights to photographs and moving images to advertisers, publishers, the
news media, and others. Getty's collection spans from the Hindenberg disaster to
the Lewinsky hug. The Internet has boosted demand and cut Getty's costs. Sales
via the Internet recently grew 164% year-to-year and accounted for 32% of
company revenues. Pricing on the Internet is firm, while salesforce productivity
is up fifty-fold! Getty's stock price, while up over 180% this year, remains
reasonable compared to other Internet companies.

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

  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 Twenty 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 1.35% for the period ended December 31, 1998 and the

outstanding during the period.

(c)   Acorn Twenty was reimbursed by the Advisor for certain net expenses from
November 23, 1998 through December 31, 1999. Without the reimbursement, the
ratio of expenses (prior to custodian fees paid indirectly) to average net
assets and the ratio of net investment income to average net assets would have
been 1.83% and (.21%), respectively, for the period ended 12/31/98 and 1.41% and

Acorn Family of Funds
    >Notes to Financial Statements

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 December 31, 1999.  Acorn
International entered into forward contracts to sell foreign currency as
described below:

     >Notes to Financial Statements

     >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.

  In accordance with the distribution requirements imposed on investment
companies, Acorn Fund, Acorn International and Acorn USA paid long-term capital
gain distributions in 1999 of $715,158,000, $135,249,000 and $27,669,000,
respectively, which was sufficient to allow each fund not to incur any income
tax. Acorn Twenty and Acorn Foreign Forty were not required to pay a long-term
capital gain distribution.

  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 follows:

</TABLE>

  At December 31, 1999, Acorn Fund had no cumulative net unrealized appreciation
on PFICs.

  At December 31, 1999, Acorn Foreign Forty had cumulative net unrealized
appreciation on PFICs of $305,000, of which $286,000 was recognized in 1999.

  Distributions relating to PFICs are treated as ordinary income for Federal
income tax purposes.

  Dividends payable to shareholders are recorded by the Funds on the ex-dividend
date.

  Reclassifications have been made in 1999 for Acorn Fund, Acorn International
and Acorn USA in the accompanying analysis of net assets from accumulated net
realized gain on sale of investments to paid-in-capital of $95,281,000,
$19,806,000 and $4,308,000, respectively. A reclassification was also made in
Acorn International of $1,526,000 from undistributed net income to paid-in-
capital. All reclassifications were made to reflect differences between
financial reporting and income tax basis and had no impact on net asset value.

3.  Transactions with Affiliates
