LOGO: SQUIRREL CHATTER:
      WHEN RAILROADS WERE THE "NEW ECONOMY"



Watching the boom and bust cycle of Internet stocks in recent months, I thought
it might be interesting to review what happened when "New Economy" industries
took over 150 years ago. The predecessor to today's Information Revolution (the
Internet, the cell phone and the personal computer) was the industrial
Revolution. The steam locomotive, invented in 1829 in England, was the pivotal
invention of the Industrial Age. Soon after the first locomotive ran from
Manchester to Liverpool, "dot.rr" ventures began to spring up. By the end of
1845, 1,428 railway ventures had been proposed and were waiting to receive
Parliamentary permission to raise capital./1/ A great IPO boom occurred in
Britain, with all the greed, hype, and chicanery we know and love today. As
always, the bubble burst shortly thereafter, bringing the usual losses and
complaints.



BUILDING THE UNION PACIFIC

In America, railroads were built with equal enthusiasm. In 1830 there were only
32 miles of U.S. railroad track. By 1870 that number reached 125,000 miles. The
need for a transcontinental railroad was visualized as early as 1840, at a time
when railroads were primitive and the West was only inhabited by Indians, who
were considered to be hostile savages. The discovery of gold in California in
1848, followed by additional gold and silver strikes in Colorado and Nevada,
made a railroad more desirable, although it was clear that any construction
still would have to be subsidized by the government. In the mid-1850s, Congress
debated building a railroad from the Midwest to California, but the slavery
issue blocked any decision. The Southern states wanted a route through Texas and
Arizona. The North, intent on blocking the extension of slavery into the West,
wanted a central route through Nebraska and Colorado.

When the Civil War started, the Southerners left Congress, allowing the
remaining Northern government to build the central route. The route was to be
from the Missouri River (eventually Omaha) through Nebraska and Wyoming to
Ogden, Utah. The Central Pacific Railroad was to build east from California
through the Sierra Nevada Mountains and link up to the Union Pacific.

The chief construction engineer of the Union Pacific was General Granville M.
Dodge. He was experienced in railroad building and had also been a successful
combat commander in the Union Army. Building a railroad through uninhabited
areas, fighting Indians along the way, matched Dodge's abilities perfectly. The
railroad "army" Dodge commanded was made up of 10,000 workmen plus 10,000 draft
animals. Advance parties of surveyors located the route. Graders, who could
grade three miles a day on level plains, followed them. The graders operated
several hundred miles ahead of the tracklayers. Bridge building gangs could
construct major bridges in 30 days or less. To accommodate the workers, a
floating civilian population of gamblers, bartenders and prostitutes built
temporary towns along the route. During 1867 and 1868, the Union Pacific had
periods in which they laid four to seven miles of track per day!/2/



OPENING THE WEST

Low freight rates transformed the country (cheap communication is doing the same
thing today). In the 1850s it cost $0.30 per pound to ship goods from St.
Joseph, Missouri to Ogden, Utah, a 1,000-mile trip ($0.60 per ton-mile). At this
rate, only the most valuable and essential items were worth shipping. The Union
Pacific was finished in 1869. By 1880, freight rates were down to $0.02 per
ton-mile, one-thirtieth of pre-rail costs. A dozen years later, the rate was
less than a penny as competition between railroads forced rates ever lower. New
industries were created as the agricultural bounty of the Midwest was made
accessible. The introduction of an inexpensive means to ship grain, cattle, coal
and mineral ore to the East brought prosperity and wealth to the West. New
cities sprung up and old ones withered./3/ Charles F. Adams, Jr., of the
Massachusetts Adams', was a serious scholar of the railroads and later became
president of the Union Pacific. He wrote in 1871:

                                       2
<PAGE>

      [The railroad] makes the grass grow in the once busy streets of small
      commercial centers like Nantucket, Salem and Charleston. ... It threatens
      to make a solitude of the once busy wharves of Boston, and it fills New
      Hampshire with deserted farms. ... Meanwhile San Francisco and Chicago
      spring up like a very palace of Aladdin.

Adams was right about San Francisco and Chicago. In 1835, San Francisco was only
one shanty. In 1869 it was a big city of 170,000 and booming. The statistics for
Chicago are even more remarkable. In 1830 no more that 100 souls survived in "an
uninviting swamp." By 1847, there was a town of 8,000; ten years later, 100,000;
and in 1869 it was a major city of 300,000 and the fastest growing city in
America./4/

Investors "downstream from the railroads" -- those that used, rather than ran,
the railroads -- made some impressive fortunes. But how successful were the
mighty railway companies themselves? Not very. Over the 70 years that marked the
strongest period in rail history (1860-1930), most railways went broke at least
once because of fierce competition. The different rail companies tried to
collude to keep rates up, but always one competitor would break ranks and
re-ignite a rate war. Bankruptcies were frequent (as with the airlines today)
but the railroads continued to operate in receivership. The Union Pacific itself
went bust in 1893./5/ Adams wrote the following about railroad investments. If
you care to, read it twice replacing "railroad" with "Internet". Either way, it
works.

      People continuously refer to the brilliant successes in railroad
      enterprises; they do not so often count the failures. ... The profits upon
      railroad enterprises, as a whole, are not excessive; the business is one
      which affords in this country even less than the average return upon the
      capital invested in it. [His estimate: no more than 6.8% return on assets,
      and this was before the depression of 1873.]/6/

Railroads were the dominant industry from 1860 to 1930 but have been displaced
by truck lines. Today, the railroad industry makes up only 0.4% of the S&P 500.
Pop quiz: Name one of the manufacturers of steam locomotives in 1900./7/

The Internet is promoting growth in much the same way the railroads did.
Competition among Internet companies is preventing them from making substantial
profits but companies that have learned how to use the Internet to improve their
operations -- many of those stodgy "Old Economy" names -- are discovering new
avenues for growth and profits.

--------------------------------------------------------------------------------
LOGO:    PERFORMANCE REVIEW     WANGER U.S. SMALL CAP

Hitting its first rough patch since its launch five years ago, Wanger U.S. Small
Cap fell 14.6% during the first half of the year vs. the Russell 2000, up 3.0%.
While short-term performance lagged, the Fund's 19.9% average annual return
outscores the Russell's 15.3% average annual gain since the Fund's inception
(5/3/95 - 6/30/00).

What happened? As you might expect, the (mis)behavior of our technology holdings
hurt the Fund's overall performance. In an unfortunate reversal, the tech names
that have punished us so far in 2000 are the same stocks that pushed the Fund to
the top of our peer group during the second half of last year.

Internet businesses are difficult to value so most investors let the stock
market dictate value and follow its lead. We know Internet stocks are worth
something. Our goal is to buy them at reasonable values. We paid reasonable
prices for the "real world" businesses of Micros Systems, Project Software and
Aztec Technology, without having to pay much for the upside potential of their
Internet ventures. During the Internet rally in the second half of 1999, these
companies doubled or tripled as the market fell in love with every Internet
possibility. Last quarter, however, the romance was over. These same businesses
were hurt by their Internet association and are essentially back where they
started. In addition, revenue shortfalls announced by Micros Systems, RCN and
Sykes Enterprises crushed their stock prices.

While our technology exposure has hurt Fund performance, we want to assure
shareholders that we are not being overly aggressive in this area. As of June
30, 22% of the Fund's assets were invested in technology stocks, with an
additional 13% in communications stocks, some of which mimic the techs (RCN, a
new age fiber optics telecom network) and some of which act nothing like a tech
stock (Commonwealth Telephone, a local phone company). Overall, our tech
weighting has been, and remains, close to the weighting of the Russell 2000
Index.

Despite the wrenching readjustment we've been through, many of our top holdings
are strong growth companies trading at record-low valuations. When investors
start looking for quality, we think these names should get attention, pushing
valuations back upward.

LOGO: PERFORMANCE REVIEW    WANGER INTERNATIONAL SMALL CAP

Wanger International Small Cap was off 3.1% for the first six-months of the
year, faring better than the 4.1% decline of the EAFE Index but finishing behind
the EMI World ex U.S., which eked out a 0.3% return for the period. With U.S.
market volatility rippling across foreign borders, small-cap stocks around the
globe lost ground during the period, but we remain excited about the portfolio's
prospects going forward.

For instance, although Omni Industries put a damper on short-term returns, our
conviction in the stock -- historically an excellent long-term performer for the
Fund -- remains intact. A Singapore-based contract manufacturer, Omni declined
amid concerns about component shortages. Despite this set back, we think Omni
has what it takes to address these issues and maintain the profitable niche it
has established within the technology outsourcing arena.

Internet consultants, such as FI Systems (France) and Icon Medialab (Sweden),
retreated as foreign investors followed the lead of their U.S. counterparts and
sold off technology names indiscriminately. We believe that these premier
consultants are set to prosper, regardless of which businesses ultimately
dominate the Internet. The consultants are not unlike the shovel salesmen in a
gold rush: Only a few miners strike it rich but all need shovels for digging.

On the upside, UK-based electronics firm Chloride Group surged, propelled by
strong earnings as well as by management's optimistic outlook for increased
demand. Also in the technology camp, German semiconductor manufacturer Dialog
Semiconductor rocketed upwards, thanks to strong demand for its mobile phone
chips.

Outsourcing, a key portfolio theme, was also represented among the Fund's
leading names. Dutch temporary employment provider Unique International rose
briskly, as did Patheon, a Canadian provider of outsourced drug manufacturing
and development services.

As always, we remain committed to finding the best small companies in the world
to include in the Wanger International Small Cap portfolio. Our philosophy is to
own these stocks through up and down market cycles, allowing the value to build
over time. Despite the bumpy road we traveled this period, we remain very
positive about what lies ahead. International markets are changing faster than
we ever expected as an emerging local interest in equities is helping to expand
and support the pool of investment options.

--------------------------------------------------------------------------------
LOGO:  PERFORMANCE REVIEW     WANGER TWENTY

Wanger Twenty was up 2.9% for the first half of the year while the S&P MidCap
400 gained 9.0% and the Lipper Mid Cap Funds Index returned 8.7%. The S&P 500
was off 0.4%. The market's focus on growth stocks, particularly in technology,
hurt our more value-oriented portfolio in the first quarter but we regained some
ground in the second quarter (up 0.9% while both mid-cap indexes declined more
than 3%) when the tech bubble burst.

Several of the Fund's winners shared a common theme: They provide tools to
high-growth industries like technology, telecommunications, and the life
sciences. Techne, for example, rose 88% during the quarter as investors realized
biotech and drug companies will likely increase spending on the company's
cytokines (cellular proteins used to test drug/cell interaction) and reagents
(enzymes used in chemical reactions as catalysts) for research and development
now that the human genome has been sequenced. Similarly, Waters gained 31% as
growth accelerates in its mass spectrometry (a devise used to measure the
molecular weight of a substance using light) business due to increased protein
analysis following the gene-sequencing breakthrough. Tektronix, a winner last
quarter, rose 32% after reporting strong results in its test and measurement
instrument business, which sells products to the high-growth technology and
telecommunications industries.

Two significant losers during the quarter were Reynolds & Reynolds, a
manufacturer of business forms and computer systems used by car dealers, and H&R
Block, a familiar name in tax preparation services. Reynolds & Reynolds lost 32%
after announcing a dilutive equity transaction with partner General Motors. H&R
Block fell 27% on disappointing earnings news that followed this year's tax
season. Both of these names have strong franchises in growing industries and
generate significant cash flow. Therefore, we are willing to be patient until
the market comes to appreciate the value of their businesses.

Following our "downstream from technology" theme, Wanger Twenty chose to invest
in companies benefiting from technology while avoiding pure technology names.
This theme is not only prevalent in stocks mentioned previously, but also in
more prosaic industries. Herman Miller, for example, manufactures office
furniture, hardly a high-tech industry. Miller does, however, use technology
extensively to provide customers with three-dimensional product models on its
web page. By taking advantage of technology's increasing power and decreasing
price, Miller has become the premier company within its industry.

Ending the quarter on a high note, Wanger Twenty was up 8.9% in June. The market
appears to be favoring mid-cap stocks, as this group has outperformed large- and
small-cap stocks so far this year.* This environment should prove favorable to
the Fund's concentrated, mid-cap approach going forward.

*From January 1 through June 30, 2000, the S&P MidCap 400 was up 9.0% while the
 large-cap focused S&P 500 was down 0.4% and the small-cap Russell 2000 Index
 posted a 3.0% return.

 Part of the performance shown is due to the Fund's purchases of securities in
 IPOs. Some of those securities were held as investments in the Fund and others
 were sold soon after purchase. It is anticipated that the Fund's purchases of
 securities in IPOs may continue in the future, but continuation is not certain
 and the impact of IPO purchases is likely to decline as the Fund grows larger.

LOGO:  PERFORMANCE REVIEW     WANGER FOREIGN FORTY

Wanger Foreign Forty gained 9.8% during the first half of the year, strongly
outperforming the EAFE Index, off 4.1%, and the SSB World ex-U.S. Cap Range
Index, down 1.3%. As of June 30, the Fund's total return ranked first among the
129 funds in the Lipper Variable Annuity International Funds category for the
one-year period ended June 30, 2000.

Recent additions from Australia served the Fund well. ERG Limited, a producer of
smart cards used in public transportation and telecommunications, was up 74%,
and Computershare, a financial software company, saw a 30% gain. The Fund also
benefited from participation in the initial public offering of Bookham
Technology, a UK manufacturer of optical components used in telecom networks.*
Among our veteran holdings, Amdocs, an Israeli billing software developer, rose
116%, and Belgium's Audiofina, a European broadcast media leader, increased 72%.

Several of our strong, long-term performers gave back some ground over the six
months. Singapore-based Star Cruises hit choppy water, sinking 47% on news of
slowing demand across the cruise industry. However, we feel Star will see a
turnaround as Asia's middle class expands. Telecommunication stocks declined in
the second quarter hurting UK telecom company Thus, off 40%, and Japanese call
center operator Bellsystem24, down 43%.

The world of equity investing outside the United States is changing faster than
we ever imagined it would. In Europe, for example, new equity issues are
breaking all previous records. Much of this cash is funding young, fast-growing
enterprises that are going public for the first time. As buyers of small- to
mid-cap stocks, we should benefit from a larger pool of stocks and a growing
local interest in investing.

*Part of the performance shown is due to the Fund's purchases of securities in
 IPOs. Some of those securities were held as investments in the Fund and others
 were sold soon after purchase. It is anticipated that the Fund's purchases of
 securities in IPOs may continue in the future, but continuation is not certain
 and the impact of IPO purchases is likely to decline as the Fund grows larger.

(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

     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.

NOTES TO FINANCIAL STATEMENTS (unaudited)


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
Statement of Operations.

FEDERAL INCOME TAXES, DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

              PROSPECTUS DATED MAY 1, 1999 OF WANGER ADVISORS TRUST


                  PROPOSED ADVISORY AGREEMENT. On June 9, 2000, Wanger Asset
         Management, L.P. ("WAM"), the Funds' investment adviser, and Wanger
         Asset Management, Ltd., the general partner of WAM, entered into an
         Agreement and Plan of Merger ("Merger Agreement") with Liberty
         Financial Companies, Inc. ("Liberty") and WAM Acquisition L.P., a newly
         formed limited partnership ("Liberty Sub"). Under the Merger Agreement,
         Liberty Sub would be merged with and into WAM (the "Merger"). WAM would
         be the surviving entity and would be a wholly-owned subsidiary of
         Liberty. After the merger, WAM will operate under the name Liberty
         Wanger Asset Management, L.P. ("Liberty WAM").
                  On July 6, 2000, the board of trustees of Wanger Advisors
         Trust (on behalf of each of the Funds) approved a new investment
         advisory agreement with Liberty WAM (the "Proposed Advisory Agreement")
         that, if approved by shareholders, will become effective upon the
         consummation of the Merger. You will receive a proxy statement
         describing the Merger and the Proposed Advisory Agreement in more
         detail and seeking approval of the Proposed Advisory Agreement by the
         shareholders of each Fund. The Merger Agreement provides that the
         Merger is conditioned upon the shareholders of Wanger U.S. Small Cap
         and Wanger International Small Cap approving the Proposed Advisory
         Agreement and certain other conditions are met.
                  Subject to the receipt of the necessary shareholder approvals
         and the satisfaction of other conditions contained in the Merger
         Agreement, it is anticipated that the Merger will occur as soon as
         reasonably practicable after the requisite shareholder approvals have
         been obtained.
