FROM CHAIN MAIL TO E-MAIL
A FIVE-MINUTE HISTORY OF THE WORLD


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

                                        2

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 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.

Wanger Advisors Trust      1999 Annual Report

PERFORMANCE REVIEW     WANGER U.S. SMALL CAP

Your Fund outperformed the stock market indexes both large and small in 1999.
Wanger U.S. Small Cap returned 25.1% last year, beating the small-cap Russell
2000's 21.3% return and the large-cap S&P 500's 21.0% return. Most of our
performance came in the final quarter of the year, when Wanger U.S. Small Cap
gained 17.8%, 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 your 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
will 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?

Wanger Advisors Trust      1999 Annual Report

PERFORMANCE REVIEW   WANGER INTERNATIONAL SMALL CAP

Wanger International Small Cap enjoyed a record year. Our gain of 126% was more
than double our nearest benchmark (the Lipper International Small Cap Funds
Index had a return of 63%) and we ranked first of the 126 funds in the Lipper
Variable Annuity International Funds category for the 1-year period ended
12/31/99.

   As we mentioned in the previous report, our overweight position in Asian
markets drove our performance through June. Japanese stocks rose 116%, Singapore
130% and Malaysian names were up 105% through June 30. In the second half of the
year, it was Europe's turn. Our French stocks were up 129%, German names
increased 140%, and in Sweden we saw gains of 204%. In several Asian markets,
small caps outperformed large caps during the period, but the reverse was true
in Europe.

   As our returns illustrate, we did a number of things well in 1999. We picked
the right sectors and the right stocks and we were able to do this while
maintaining the high level of diversification that is a cornerstone of our
investment strategy.

   In Asia our two winning themes were outsourced manufacturing (largely in Hong
Kong and Singapore) and technology (mostly in Japan). Omni Industries and
Venture Manufacturing both scored gains of 200% or more and made $15 million for
the Fund. Trans Cosmos and Datacraft were up even more with Trans Cosmos, a
Japanese Internet conglomerate, up fifteen fold for a gain of nearly $15
million. Credit for these picks goes to Wanger Asset Management's Roger Edgley
and Michael King.

   In Europe, our most lucrative stock picks were in Internet consulting and in
media. Peter's close eye on Sweden got us into their world-class Internet
consulting stocks early. We are now following this theme into other markets.
Looking forward, we will continue to strive to invest in international companies
that are niche leaders.

Wanger Advisors Trust      1999 Annual Report

PERFORMANCE REVIEW     WANGER TWENTY

Wanger Twenty finished 1999 up 34.3%, outperforming the 19.4% S&P MidCap 400
return and the S&P 500's 16.2% gain for the period beginning February 1 and
ending December 31, 1999. Looking back on the fund's first 10 months, we are
pleased with our start and we thank our shareholders for the confidence they
showed as initial investors.

   Several stocks contributed to Wanger Twenty's performance. The biggest
winners were our telecommunications stocks. Telephone and Data Systems, a
cellular phone and personal communication services provider, rose 138% during
the 10 months following the company's announcement of the sale of its Aerial
Communications subsidiary to Voicestream Wireless. RCN, a competitive local
exchange carrier (CLEC), gained 74% 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% for the Fund during the
period. McLeod, like RCN, is a CLEC, but provides services to businesses rather
than residential communities. Other strong performing stocks included Liberty
Media, up 119% for the period, and AES Corp, an independent power producer, up
106%.

   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.

   Our success in these first months is largely due to the collaborative efforts
of the Wanger Asset Management research team. Our sincere thanks go to Ralph
Wanger, Chuck McQuaid, Rob Mohn, Laura McKenna, Jason Selch, and Ben Andrews.

Wanger Advisors Trust      1999 Annual Report

PERFORMANCE REVIEW     WANGER FOREIGN FORTY


Wanger Foreign Forty was up 83.9% for the 10-month period ended December 31,
1999, more than double the returns of the Salomon Smith Barney Cap Range $2-10
Billion Index (+24%), the EAFE (+ 27%) and the Lipper International Funds Index
(+38%). Launched on February 1, 1999, we are very pleased with the Fund's strong
beginning and hope that our shareholders are too.

   Much of the gain for the period came in the fourth quarter as the Fund
advanced 57.9% on the strength of our information technology (IT) stocks. There
was no slowing of the Fund's largest position, Softbank. Up a staggering 1,169%
for the 10-month period, this Japanese Internet company was an obvious winner
for the portfolio. Spain's Jazztel, a telecommunications services company, was
up 311% for the period and was also among the Fund's top performers. Benefiting
from Internet-related services, two Italian publishing names -- Editoriale
L'Espresso (+266%) and SEAT Pagine Gialle (+204%) -- posted strong 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.

   *Annualized

(a)  In accordance with a requirement of the Securities and Exchange Commission,
     this 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 1.04% for the year ended December 31, 1997, 1.19% for the year ended
     December 31, 1996 and 2.00% for the period ended December 31, 1995.

(b)  The fund was reimbursed by the Advisor for certain expenses from May 3,
     1995 through December 31, 1995. 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 for the period
     ended December 31, 1995, would have been 2.35% and (1.71%), respectively.

(c)  Net investment income (loss) per share for the years ended December 31,
     1999, 1998, 1997 and 1996 was based upon the average shares outstanding
     during the period.

(d)  Total return is not annualized for periods less than one year.

     1995 through December 31, 1995. 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 for the period
     ended December 31, 1995, would have been 4.20% and (2.69%), respectively.

(c)  Net investment income (loss) per share for the years ended December 31,
     1999, 1998, 1997 and 1996 was based upon the average shares outstanding
     during the period.

Wanger Advisors Trust      1999 Annual Report

NOTES TO FINANCIAL STATEMENTS


1. NATURE OF OPERATIONS
Wanger US Small Cap, Wanger International Small Cap, Wanger Twenty and Wanger
Foreign Forty ("the Funds") are series of Wanger Advisors 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. The Funds are available only for allocation to certain life insurance
company separate accounts established for the purpose of funding qualified and
non-qualified variable annuity contracts, and may also be offered directly to
certain types of pension plans and retirement arrangements.

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 readily available and any other assets
are valued 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 Fund. Interest income is recorded on the
accrual basis and includes amortization of discounts on money market instruments
and on 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 estimated.

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 the Fund's investments and other assets, less liabilities, by the
number of Fund shares outstanding.

CUSTODIAN FEES
Custodian fees are reduced based on each Fund's cash balances maintained with
the custodian. The amount is disclosed as a reduction of total expenses in the
Statements of Operations.

FEDERAL INCOME TAXES, DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
The Funds have complied with the special provisions of the Internal Revenue Code
available to regulated investment companies and, in the manner provided therein,
distribute all of their taxable income, as well as any net realized gain on
sales of investments and foreign currency transactions reportable for federal
income tax purposes.
   Wanger International Small Cap has elected to mark-to-market its investments
in Passive Foreign Investment Companies ("PFICS") for income tax purposes. In
accordance with this election, the Fund had no unrealized appreciation from
investments in PFICs at December 31, 1999. Cumulative net unrealized
appreciation recognized in prior years on PFICs sold in 1999 amounted to
$83,762.
   Wanger Foreign Forty has also has elected to mark-to-market its investments
in Passive Foreign Investment Companies ("PFICS") for income tax purposes. In
accordance with this election, the Fund had $5,826 of unrealized appreciation
from investments in PFICs at December 31, 1999.
   Dividends and distributions payable to each Fund's shareholders are recorded
by the Fund on the ex-dividend date.
   Reclassifications have been made in 1999 for Wanger International Small Cap
and Wanger Twenty in the accompanying analysis of net assets from undistributed
net investment income to net realized gain on the sale of investments of
$964,907 and $28,532, respectively. These 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
The Fund's investment advisor, Wanger Asset Management, L.P., ("WAM") furnishes
continuing investment supervision to the Fund and is responsible for overall
management of the Fund's business affairs. Each Fund pays WAM a monthly advisory
fee based upon average daily net assets at the following rates:

WANGER U.S. SMALL CAP
Average Daily Net Assets
   For the first $100 million   1.00%
   Next $150 million             .95%
   In excess of $250 million     .90%

<PAGE>
Wanger Advisors Trust      1999 Annual Report

NOTES TO FINANCIAL STATEMENTS


WANGER INTERNATIONAL SMALL CAP
Average Daily Net Assets
   For the first $100 million   1.30%
   Next $150 million            1.20%

WANGER TWENTY
On average daily net assets      .95%

WANGER FOREIGN FORTY
On average daily net assets     1.00%

The investment advisory agreement also provides that WAM will reimburse the
Funds to the extent that ordinary operating expenses (computed based on net
custodian fees) exceed a percentage of average net assets. This amount is 1.50%
for Wanger U.S. Small Cap, 1.90% for Wanger International Small Cap, 1.35% for
Wanger Twenty and 1.45% for Wanger Foreign Forty. WAM was not required to
reimburse Wanger U.S. Small Cap or Wanger International Small Cap under these
agreements for the year ended December 31, 1999. Wanger Twenty and Wanger
Foreign Forty were reimbursed $26,027 and $37,004, respectively, for the period
ended December 31, 1999.
   Certain officers and trustees of the Trust are also principals of WAM. The
Trust makes no direct payments to its officers and trustees who are affiliated
with WAM. The Funds paid the following trustees' fees and expenses to trustees
not affiliated with WAM:

                                           1999
Wanger U.S. Small Cap                   $31,610
Wanger International Small Cap           16,817
Wanger Twenty                               251
Wanger Foreign Forty                        121

WAM advanced $100,000 in connection with the organization and initial
registration of Wanger U.S. Small Cap and Wanger International Small Cap. These
costs are being amortized and reimbursed to WAM over the period May, 1995
through April, 2000. WAM paid all organization costs associated with the
organization of Wanger Twenty and Wanger Foreign Forty. These costs amounted to
$ 20,816. WAM will not be reimbursed for these costs by the Funds.
   WAM Brokerage Services, L.L.C., a wholly-owned subsidiary of WAM, is
the distributor of each Fund's shares and receives no compensation for its
services

4. BORROWING ARRANGEMENTS
Wanger U.S. Small Cap and Wanger International Small Cap participate in a
$250,000,000 credit facility which was entered into to facilitate portfolio
liquidity. No amounts were borrowed under this facility during 1999.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements.

Our procedures included confirmation of investments owned as of December 31,
1999, by cor respon dence with the custodian and brokers. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to

the results of their operations and changes in their net assets and financial
