Berger Funds o September 30, 2000 Combined Annual Report

A Message To Our
Shareholders
--------------------------------------------------------------------------------

Dear Berger Investor:

With apologies to Charles Dickens, this past fiscal year, which ended September
30, was "the best of times and it was the worst of times."

The period began with the December quarter of 1999, during which the U.S. stock
market moved smartly higher, led by substantial gains in technology stocks.
Investor enthusiasm for tech stocks was fueled by accelerating revenue and
earnings growth, which were driven by the rapid build-out of the Internet and
aggressive deployment of e-commerce initiatives by both new-economy companies
and established Fortune 1000 "brick and mortar" companies.

Repeated increases in interest rates and warnings from the Federal Reserve Board
that above-trend economic growth was increasing the risk of inflation were no
deterrent through most of the first quarter of 2000. A correction finally got
under way in March, gathered steam and ultimately took the tech-heavy NASDAQ
Composite Index down 37% by the end of May. Then, on increasing evidence that
economic growth was slowing, a consensus developed that the Federal Reserve had
largely completed the cycle of raising interest rates. Stocks were able to
rally, with fits and starts, through the end of August. After Labor Day, though,
sentiment deteriorated because of earnings concerns. High energy prices also
added to fears that the slowdown in the economy might end in recession rather
than a soft landing. The correction in technology stocks resumed and continued
through the September fiscal year-end, exacerbated by negative earnings
pre-announcements from some high-profile tech companies such as Intel and
Lucent.

The Main Event

Technology has been so much the main event in the stock market over the past two
years that it seems as if it is the only event, and with good reason. The
current, record-setting economic expansion that began early in the decade,
accelerated in the later 1990s and continues today, has been driven by capital
spending, and the share of that spending going to investment in technology has
been increasing. These trends have culminated in substantial productivity gains,
enabling the economy to grow more rapidly without provoking inflation than at
any other time in the post-war era.

Deregulation here and abroad, democratization and privatization around the globe
and freer trade have stimulated global economic growth and opportunities for
businesses everywhere. These factors have also intensified the level of
competition that businesses face, leaving companies with little or no pricing
power. This is driving investment in technology to improve efficiency and
results. These investments are continuing at a rapid rate as companies strive to
gain any possible competitive advantage.

Valuation Correction

We see the correction we have experienced in technology stocks as largely a
correction in valuations. Even though we have seen some evidence of slowing
growth in some areas of technology, such as sales of wireless handsets, PC's and
some semiconductor equipment and components, we believe that the correction is
not a reflection of a significant deterioration in the fundamentals that drove
the prior advance. Many key areas of technology are still exhibiting very strong
growth. The larger issue is that valuations of tech stocks became very high as
the market discounted their high growth rates and bright futures. At high
valuation levels, any real or perceived weakness in earnings or future growth
prospects has a pronounced negative effect on prices.

Any general uncertainty about the economy, or the outcome of the elections or in
the direction of interest rates also may cause investors to shorten their time
horizons. This too, has a negative effect on growth stock prices since growth
stocks in general, and technology stocks in particular, are priced to a great
extent on future as opposed to present sales and earnings. This is why we have
written in the past that we expect a higher level of volatility in the market
and that a correction can be a healthy thing for the long-term investor.
Corrections return great, leading growth stocks to attractive valuation levels
and purge the market of excessive speculation, which can reset the stage for a
renewed and sustainable advance.

Capital Gains

A side effect of the market volatility we have experienced during the last year
will be apparent in the capital gains investors will see in 2000. With the
dramatic appreciation in many stocks during the year, portfolio managers often
recognized that selling a stock was prudent. Despite lowering overall turnover,
our managers occasionally found it necessary to sell stocks when some investors
redeemed shares during market downturns. The result has been larger than normal
capital gains for some of the funds. For more information on your fund's
estimated capital gains, visit our Website at www.bergerfunds.com or call (800)
551-5849.

Regardless of the short-term volatility in the market, we at Berger remain
committed to the same investment philosophy

pioneered by Bill Berger more than 25 years ago. We know that achieving our goal
of providing investors with consistently competitive performance in every Berger
Fund can only be reached by adhering to our disciplined, fundamental,
stock-by-stock approach to investing and remaining focused on the long term.

Optimistic Outlook

We remain constructive on the outlook for the economy and the markets. The
economy has slowed to a healthy, sustainable growth rate. We believe the
technology-driven productivity revolution is alive and well. Inflation appears
to be very much under control, and interest rates may be poised to moderate.
Corporate earnings performance remains at a generally high level. In this
context, we view corrections as buying opportunities, and we encourage investors
to take a long-term approach by employing dollar-cost-averaging as a technique
to help smooth the effect of short-term market swings on their long-term
results.

Time-proven Basics

For more than 25 years we have advocated basic investment principles to our
investors:

o    Time and diversification are an investor's greatest allies against risk.

o    Those who take a long-term view are often the most successful investors.

o    Investing regularly is an excellent way to reach one's financial goals.

o    It's time in the market, not market timing, that counts most.


Sincerely,

/s/ JACK R. THOMPSON                                 /s/ JAY W. TRACEY

Technology Fund               PORTFOLIO MANAGER COMMENTARY  WILLIAM F. K. SCHAFF
--------------------------------------------------------------------------------

Performance

The Berger Information Technology Fund (the "Fund") gained 114.97% (investor
shares) and 115.86% (institutional shares) for the fiscal year ended September
30, 2000. Its benchmark, the Wilshire 5000 Index,(1) gained 17.56% over the same
period.

The technology sector outshone all others for the first half of the fiscal year,
before high volatility roiled the sector, shaking the confidence of many
technology investors and driving down prices. Since that time, Internet and
e-commerce companies have taken the biggest hit. On the upside, technologies
that drive corporate Information Technology (IT), including optical networking
technology and wireless components, infrastructure and applications continued to
experience strong growth.

Last year--1999--was a time of euphoria when the stock of almost any
technology-related company with an exciting story would rise unconditionally.
Next year is likely to be a year when investors get back to solid fundamentals
and valuations. It appears that 2000 will be remembered as a time of confusion
as investors deal with the transition.

Period in Review

Clearly, technology is a much stronger force in the economy than ever before,
but speculation is still speculation, whether in real estate or the stock
market. Having said that, there are still many technology companies that are not
overpriced. Now that more of the nonprofitable technology companies using
acronyms such as B2C, B2B and B2B2C are filing with their local bankruptcy
court, we can focus on more profitable businesses. We always look for the start
of IBM's new upgrade cycle because the economic benefits seem to trickle down to
many other companies. One group of potential beneficiaries are mainframe
software vendors. Stocks of these companies have been beaten down tremendously
but still generate solid cash flows and have pristine balance sheets--not bad
defensive characteristics.

The Fund experienced strong gains by investing primarily in profitable companies
with longer performance track records. Applied Micro Circuits was a strong
performer all year, in addition to storage vendors Network Appliance and EMC.
Our largest position, BEA Systems, the leading middleware applications
integrator, also performed well.

We maintained large positions in e-commerce application integrators and supply
chain software vendors such as i2 and Manugistics. We think of this as the glue
that makes e-commerce work and that has contributed much to the productivity
gains seen to date. We believe some of these investments will be both short- and
long-term, as e-commerce will continue to be a growing part of our lives.

Though the Fund has few direct Internet plays, it does contain many of the
software companies that produce the required nuts and bolts of e-commerce
infrastructure, such as Oracle and Siebel Systems. The Fund benefited greatly
over the fiscal year from their presence.

On the downside, the few chips stocks we own were the weakest performers, but
not unexpectedly because they had been the best performers the first half of the
year. The biggest disappointment was Computer Associates, the largest
independent mainframe software vendor, which preannounced a weak quarter once
again. Another negative contributor to performance was Lucent Technologies, one
of the few "value" plays in technology, which continues to get cheaper. Despite
some of these performance setbacks, we continued to have more winners than
losers, and our top 10 positions, representing more than 30% of the portfolio,
were up strongly.

Summary

Looking ahead, we see signs that the economy will continue to slow. However,
technology will remain the largest weapon for businesses to increase
productivity and enhance their competitive position in the global marketplace.
One of the best-performing sectors for 2001 could be security and related
security vendors. As e-commerce grows, so will all the related security issues.
With the advent of digital certification, there will be greater concern for
privacy, authentication, authorization and certification. Leading-edge biometric
technologies will also finally become broadly commercially viable in
2001--expect to see some big announcements. However, given the confusion that is
likely to be rampant, homework will have to be done to differentiate winners and
losers once again.

Past performance is no guarantee of future results.

* Past performance is no guarantee of future results. Fund performance shown
reflects the unusually favorable market conditions that existed in 1999 which
likely are not sustainable as market conditions change. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue. Performance data for the Investor Shares include periods prior to
the adoption of class designations on July 2, 1999, and therefore do not reflect
the 0.25% per year 12b-1 fee applicable to the Investor Shares. This would have
reduced the Investor Shares' return.

Generation Fund                PORTFOLIO MANAGER COMMENTARY   MARK S. SUNDERHUSE
--------------------------------------------------------------------------------

Performance

The Berger New Generation Fund ("the Fund") had a very good fiscal year ended
September 30, 2000, gaining 67.16% (Investor Shares) and 65.68% (Institutional
Shares) compared with 13.27% for the Standard & Poor's (S&P) 500 Index(1) and
23.39% for the Russell 2000 Index.(2) This solid performance was primarily
driven by stock selection, although our relatively aggressive weightings in
technology, healthcare and energy also helped.

Period in Review

We remain focused on selecting those companies that have a fit in this
ever-changing world of business. When evaluating securities we first look for
growth, both in terms of revenues and earnings. Second, we look for companies
that have a defensible business plan. Finally, we seek signs of assurance that a
company's competitive position is strong and that its product or service can add
meaningful value to the end customer.

In technology, the Fund benefited from holdings in companies that supply
infrastructure for the Internet build-out. Component suppliers Applied Micro
Circuits, SDL Inc. and JDS Uniphase, and equipment supplier, Juniper Networks,
all did very well. We remain bullish on many of the component and equipment
companies that are supplying innovative, market-leading solutions to service
providers, which are, in turn, aggressively deploying those solutions to meet an
insatiable demand for increased bandwidth.

Companies supplying leading-edge software solutions that take advantage of the
Internet to deliver competitive advantages to their customers also contributed
to the Fund's good results. Among the better performers were i2 Technologies and
Ariba. These companies are in business-to-business software that helps users
expand their margins through better inventory control and purchasing. i2 and
Ariba are generalists that help a variety of businesses. Surveys of information
technology managers at major companies confirm that e-commerce spending, which
has been strong all year, should continue to grow rapidly for the foreseeable
future. We remain, therefore, optimistic about the outlook for select vendors of
e-commerce solutions. We continue to favor business-to-business e-commerce
companies, staying clear of the business-to-consumer companies that were hurt
most of the year.

The Fund's energy stocks, particularly in the oil field services area, were good
performers, including Enron, Grey Wolf, Anadarko Petroleum and Newfield
Exploration. Compared with our index, we continue to overweight this sector
because of the strong supply/demand fundamentals and the growth in "new
economy-type" utility companies.

We continue to believe that capital spending will be strong next year,
especially with fiber-optics companies. Communications service providers must
continue to spend if they wish to remain competitive. And the competitive
pressure has increased as the stock market has become more selective, favoring
those services companies that have proven growth prospects, such as Qwest
Communications International and Level 3 Communications.

In healthcare, our notable winners included leading-edge biotechnology companies
that have emerged, or are about to emerge, from the development phase with
successful new products that we believe will generate significant sales and
shareholder value. Strong performers over the year include Genentech, Immunex
and Invitrogen. Overall, we continue to remain positive on the outlook for this
sector.

Generally, the consumer sector was disappointing. In particular, the Fund's
radio broadcasting stocks were down as advertising revenues slowed over the
latter half of the fiscal year. Because of this, we sold Clear Channel
Communications. Stocks in the telecommunications industry were also down,
including Caprock, Teligent and Nextlink. The latter two companies were recently
sold. In addition, significant prior gains were given up in holdings such as
Next Level and Foundry Networks toward the end of the fiscal year.

Summary

Again, the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our aggressive growth-oriented investment
philosophy. Every day presents us with new opportunities among small, mid- and
large-cap emerging growth stocks. Rarely have there been so many companies
addressing such open-ended business opportunities as there are today. So,
whether or not small-cap stocks outperform large caps, we look forward each day
to the prospect of identifying and investing in those that are on their way to
becoming widely recognized, established growth stocks in the future.

* Past performance is no guarantee of future results. Fund performance shown
reflects the unusually favorable market conditions that existed in 1999 which
likely are not sustainable as market conditions change. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue.

Performance

The Berger Select Fund (the "Fund") had a very good fiscal year ended September
30, 2000, gaining 55.73% compared with 13.27% for the Standard & Poor's (S&P)
500 Index(1) and 43.22% for the S&P MidCap 400 Index.(2) This solid performance
was driven primarily by stock selection, although our relatively aggressive
weighting in the technology sector also helped.

Period in Review

In technology, the Fund benefited from investments in companies that supply
infrastructure for the Internet build-out. Equipment vendors Juniper Networks,
Sycamore Networks, Cisco Systems and Redback Networks did very well serving the
rapidly-growing market for high-speed data networking. We remain bullish on many
of these companies because they are among the leading suppliers of innovative
solutions to service providers, which are, in turn, aggressively deploying those
solutions to meet an insatiable demand for increased bandwidth.

Companies supplying leading-edge software solutions that take advantage of the
Internet to deliver competitive advantages to their customers also contributed
to the Fund's good results. Among the Fund's better performers were VeriSign,
which provides digital certificate services that secure e-commerce and
communications over the Internet, and Agile Software, whose collaborative
products help automate commerce between manufacturers and their suppliers and
customers. Surveys of information technology managers at major companies confirm
that e-commerce spending, which has been strong all year, should continue to
grow rapidly for the foreseeable future. We remain, therefore, optimistic about
the outlook for select vendors of e-commerce solutions.

Technology is an exciting, but risky, area in which to invest because the pace
of change is so fast, the market is so competitive and the stocks are so
volatile. We will continue to focus on innovative companies with strong,
forward-looking management teams, leading products or services, defensible
barriers to competition and rapidly growing, sustainable revenues and earnings.

In healthcare, Genentech, a leading biotechnology company with seven products on
the market and more in development, was a significant contributor to Fund
performance this year. In financial services, Schwab did well, but Nextcard was
a disappointment. Our investment in the utility Constellation Energy also aided
Fund performance.

The Fund's energy holdings did well over the year, particularly ENSCO
International and Nabors Industries, two oil services companies. Despite strong
stock performance over the past year, we remain positive on the outlook for this
sector because the earnings outlook is only getting brighter.

Generally, performance in the consumer groups was disappointing. Compared with
our index, we have been underweighted in the sector. The Fund's radio
broadcasting stocks were down as advertising revenues slowed over the latter
half of the fiscal year. Because this trend is likely to persist for another
quarter or two, we eliminated our positions in Spanish Broadcasting and Clear
Channel Communications.

Summary

Again, the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our aggressive growth-oriented investment
philosophy. Every day presents us with new opportunities among rapidly growing
companies. Rarely have there been so many companies addressing such open-ended
business opportunities as there are today. Regardless of the stock market's
short-term ups and downs, we are excited about the fundamental outlook for the
great growth companies that are leading us into the future. Because ours is a
concentrated Fund, our mandate and our continuing focus are to identify and
invest in the best of these companies.

Past performance is no guarantee of future results.

generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

(2) The S&P MidCap 400 Index is an unmanaged index, with dividends reinvested,
and is generally representative of the market for mid-sized companies. One
cannot invest directly in an index.

reflects the unusually favorable market conditions that existed in 1999 which
likely are not sustainable as market conditions change. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more

Growth Fund                   PORTFOLIO MANAGER COMMENTARY     JAY W. TRACEY III
--------------------------------------------------------------------------------

Performance

The Berger Small Company Growth Fund ("the Fund") had a very good fiscal year
ended September 30, 2000, gaining 84.27% (Investor Shares) and 85.25%
(Institutional Shares) compared with 23.39% and 29.66% for the Russell 2000
Index(1) and Russell 2000 Growth Index(2) respectively. This solid performance
was driven by stock selection, primarily, although our relatively aggressive
weightings in technology, healthcare and energy also helped.

Period in Review

In technology, the Fund benefited from holdings in companies that supply
infrastructure for the Internet build-out. Applied Micro Circuits, which makes
integrated circuits, Redback Networks, which makes high-speed access systems,
and Newport Corp., which makes components and systems for fiber-optic
communications, were some of the Fund's stocks that did well. We remain bullish
on many of the component and equipment companies that are supplying innovative,
market-leading solutions to service providers, which are, in turn, aggressively
deploying those solutions to meet an insatiable demand for increased bandwidth.

Companies supplying leading-edge software solutions that take advantage of the
Internet to deliver competitive advantages to their customers also contributed
to the Fund's good results. Among the better performers were Agile Software,
whose collaborative software products help automate commerce between
manufacturers and their suppliers and customers; Mercury Interactive, whose
software products automate Internet and other business application testing; and
Ariba, whose e-commerce software products automate the management of business
operating resources. Surveys of Information Technology managers at major
companies confirm that e-commerce spending, which has been strong all year,
should continue to grow rapidly for the foreseeable future. We remain,
therefore, optimistic about the outlook for select vendors of e-commerce
solutions.

Elsewhere in technology, semiconductor equipment stocks, strong early in the
year, weakened considerably in the last few months as the market became
concerned about the durability of the semiconductor manufacturing cycle. Also,
in software, companies whose products focus on customer relationship management
were weak toward the end of the fiscal year because of concerns that this area
had become too competitive. Two holdings in this area, ONYX Software and Primus
Knowledge Solutions, were disappointing. Technology is an exciting but risky
area in which to invest because the pace of change is so fast, the market is so
competitive and the stocks are so volatile. We will continue to focus on
innovative technology companies with strong, forward-looking management teams,
leading products or services, defensible barriers to competition and rapidly
growing, sustainable revenues and earnings.

In healthcare, our notable winners included IDEC Pharmaceuticals, which has a
good cancer product on the market and an exciting pipeline of new compounds in
development; Cephalon, whose success in treating neurological disorders with its
lead compound, Provigil, led to significant stock appreciation this past year;
and Invitrogen, who sells research tool kits to the biotech and pharmaceutical
industries. Most of the Fund's healthcare holdings produced gains, except for
Visible Genetics, which was down because of a delay in the commercial launch of
its TRUGENE HIV-1 Genotyping Kit. Overall, we remain positive on the outlook for
this sector. Our emphasis has been on biotechnology, in which a number of
companies have emerged, or are about to emerge, from the development phase with
successful new products that we believe will generate significant sales and
shareholder value.

The Fund's energy stocks, particularly in the oil field services area, were good
performers, including Pride International, National-Oilwell and Patterson
Energy. Basin Exploration was disappointing and was sold. Despite the gains
generated in this sector, we have elected to maintain our overweighting because
the earnings outlook is only getting brighter.

Generally, the consumer services area was disappointing. In particular, the
Fund's radio broadcasting stocks were down as advertising revenues slowed over
the latter half of the fiscal year. Because this trend is likely to persist for
another quarter or two, we reduced our exposure, but are holding on to
higher-quality companies such as Cox Radio and Hispanic Broadcasting, which now
offer good value. Positions were initiated in two restaurant companies:
California Pizza Kitchen and P.F. Chang's China Bistro. The restaurant industry
as a whole has shown modest improvement, but our interest in these companies was
driven by their own merits.

Summary

Again, the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our aggressive growth-oriented investment
philosophy. Every day presents us with new opportunities among small, emerging
growth stocks. Rarely have there been so many companies addressing such
open-ended business opportunities as there are today. So, whether or not
small-cap stocks outperform large caps, we look forward each day to the prospect
of identifying and investing in those that are on their way to becoming the
widely recognized, established growth stocks of the future.

Performance

The Berger Small Cap Value Fund (the "Fund") had a total return of 20.77%
(Investor Shares) and 21.09% (Institutional Shares) for the year ended September
30, 2000, compared with 23.39% for the Russell 2000 Index(1) and 15.36% for the
Russell 2000 Value Index.(2)

After six straight years of underperformance, the Russell 2000 Index outgained
large-cap indexes this fiscal year. And, while the Russell 2000 Growth Index3
outperformed its value counterpart by more than 14%, all of the outperformance
occurred between September and December 1999. Since January 2000, value has
outpaced growth by 17%. We believe this marks a turning point that will lead to
strong relative performance of value versus growth for the foreseeable future.

Period in Review

Our best-performing sector this year was energy. As crude and natural gas prices
continued to reach levels not seen since the Gulf War, stock prices climbed to
new highs. Consistent with our philosophy of buying these stocks when commodity
prices are at new lows and selling when they reach new highs, we were net
sellers of energy stocks this year. We eliminated Evergreen Resources and
Barrett Resources but continue to like Key Energy, Noble Affiliates and Mitchell
Energy.

We continued to pare back our Real Estate Investment Trust (REIT) holdings. As
spreads between REIT yields and 10-year Treasuries continue to narrow, we
believe many stocks in the group are now fairly valued, and we have reduced our
exposure accordingly. We remain focused, however, on those names that trade at a
discount to net asset value and their peer group, such as Home Properties of New
York and Highwoods Properties.

Other industries that performed well included homebuilders, banks and insurance.
As the Federal Reserve Board increased interest rates in the first half of the
year, investors shunned industries most directly impacted by higher rates,
namely homebuilders and financial institutions. We used this weakness to build
positions in homebuilding companies. As investors gained confidence that rate
hikes were nearing an end, money began to flow into these beaten down
industries. Homebuilders more than doubled off their lows, and financial stocks
rallied more than 30% off their lows. We then decreased our exposure,
eliminating Lennar and reducing Pulte, and used the proceeds to initiate a
position in Fleetwood Enterprises, which had a more attractive valuation.

Healthcare stocks contributed positively in the second half of the year.
Legislative relief for skilled nursing facilities benefited holdings such as
Manor Care and Omnicare, both of which more than doubled off their lows.

Generally, stocks in the consumer industries were disappointing. Specifically,
our holdings in retailers AnnTaylor Stores, Ross and La-Z-boy struggled through
most of the year. While we feel each of these companies' problems are short-term
in nature and will eventually reverse course, we believe that near-term caution
is warranted and selectivity is of the utmost importance. We took advantage of
market conditions and purchased new positions in companies such as Briggs &
Stratton, Tecumseh Products, Manitowoc and A.O. Smith. All of these companies
were 30--60% off their 52-week highs yet had strong balance sheets and excellent
earnings recovery probability.

One group that proved challenging was fallen growth stocks, particularly those
in the technology sector. After being our best-performing group first quarter,
technology stocks had a negative effect on Fund performance for the year. We
attribute this to a noticeable slowdown in information technology spending by
major corporations as they struggled to digest Web-enabling projects. We believe
spending will pick up as these companies seek to integrate Web applications with
existing systems, thereby benefiting IT staffing companies. Despite the negative
returns during this period, we continue to add to our holdings in companies such
as Computer Horizons, Spherion and Kronos, which should benefit from the next
wave of spending.

Summary

We are encouraged by the recent resurgence in small-cap stocks and value
investing. We remain optimistic that the renewed emphasis on valuation marks the
beginning of a longer-term trend toward the value style. While small caps as a
group have been closing the valuation gap with their large-cap peers, we
continue to believe that risk/reward characteristics still favor small caps.
This is evidenced by the growing rate of merger and acquisition activity in the
small-cap arena. In the past year, 10% of the Fund's holdings were taken over by
larger corporate entities or taken private at significant premiums. We believe
heightened merger and acquisition activity highlights how inexpensive these
stocks have become and that one way or another value will be realized.

Past performance is no guarantee of future results.

* Past performance is no guarantee of future results. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. Performance data for the Investor Shares
include periods prior to the adoption of class designations on February 14,
1997, and therefore do not reflect the 0.25% per year 12b-1 fee applicable to
the Investor Shares. This would have reduced the Investor Shares' return.

Growth Fund                   PORTFOLIO MANAGER COMMENTARY     JAY W. TRACEY III
--------------------------------------------------------------------------------

Performance

The Berger Mid Cap Growth Fund ("the Fund") had a very good fiscal year ended
September 30, 2000, gaining 95.98% compared with 43.22% for the Standard &
Poor's (S&P) MidCap 400 Index(1). This solid performance was driven almost
entirely by stock selection, although our relative overweighting in certain
technology, healthcare and energy groups, as well as our underweighting in some
consumer groups, also helped.

Period in Review

In technology, the Fund benefited from holdings in companies that supply
infrastructure for the Internet build-out. Component suppliers Applied Micro
Circuits, SDL Inc., PMC-Sierra and JDS Uniphase, and equipment suppliers Juniper
Networks, Sycamore Networks and Redback Networks, all did very well serving the
rapidly-growing market for high-speed data networking. We remain bullish on many
of the component and equipment companies that are supplying innovative,
market-leading solutions to service providers, which are, in turn, aggressively
deploying those solutions to meet an insatiable demand for increased bandwidth.

Companies supplying leading-edge software solutions that take advantage of the
Internet to deliver competitive advantages to their customers also contributed
to the Fund's good results. Among the better performers were Verisign, which
provides digital certificate services that secure e-commerce and communications
over the Internet; Software.com, which provides messaging software applications
for Internet service providers (ISPs); and Ariba, whose e-commerce software
products automate the management of business operating resources. Surveys of
information technology managers at major companies confirm that e-commerce
spending, which has been strong all year, should continue to grow rapidly for
the foreseeable future. We remain, therefore, optimistic about the outlook for
select vendors of e-commerce solutions and view corrections as buying
opportunities.

Elsewhere in technology, semiconductor equipment stocks, strong early in the
year, weakened considerably in the last few months as the market became
concerned about the durability of the semiconductor manufacturing cycle.
Holdings such as KLA-Tencor were weak, but were sold in a relatively timely
fashion. Internet Security Systems, a somewhat recent addition to our portfolio,
was down, caught in the September correction. Technology is an exciting, but
risky, area in which to invest because the pace of change is so fast, the market
is so competitive and the stocks are so volatile. We will continue to focus on
innovative technology companies with strong, forward-looking management teams,
leading products or services, defensible barriers to competition and rapidly
growing, sustainable revenues and earnings.

In healthcare, our notable winners included IDEC Pharmaceuticals, which has a
good cancer product on the market and an exciting pipeline of new compounds in
development; Medimmune, a biotechnology company with six products on the market
and many more in development; Genentech, another biotech company with seven
products on the market; and PE Corp.-PE Biosystems Group, which markets
biochemical instrument systems and associated consumable products to the life
sciences industry. There were relatively few disappointments in the sector, but
two on the downside were Gene Logic (sold during the quarter) and Antigenics.
Overall, we remain positive on the outlook for this sector. Our emphasis has
been on biotechnology, in which a number of companies have emerged, or are about
to emerge, from the development phase with successful new products that we
believe will generate significant sales and shareholder value.

The Fund's energy holdings did very well. ENSCO International, Weatherford
International, Noble Drilling and BJ Services, which are benefiting from
favorable supply/demand dynamics in their businesses, were among the Fund's
winners. Despite the gains that have been generated in this sector, we are
continuing our overweighting because the earnings outlook is only getting
brighter.

Generally, our holdings in the consumer services area were disappointing. In
particular, the Fund's radio broadcasting stocks were down as advertising
revenues slowed over the latter half of the fiscal year. Because this trend is
likely to persist for another quarter or two, we reduced our exposure but are
holding on to higher-quality companies such as Cox Radio and Hispanic
Broadcasting, which now offer good value. There were some bright spots, however.
EchoStar Communications, a direct broadcast satellite television service,
contributed to performance, as did DeVry Inc., a provider of career-oriented
technology-based education programs.

Summary

Again, the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our aggressive growth-oriented investment
philosophy. Every day presents us with new opportunities among medium-size
emerging growth stocks. Rarely have there been so many companies addressing such
open-ended business opportunities as there are today. So, whether or not mid-cap
stocks continue to outperform as they have over the past year, we look forward
each day to the prospect of identifying and investing in those that are on their
way to becoming the widely recognized, large, established growth stocks of the
future.

Past performance is no guarantee of future results. Fund performance shown
reflects the unusually favorable market conditions that existed in 1999 which
likely are not sustainable as market conditions change. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue.

Performance

For the year ended September 30, 2000, the Berger Mid Cap Value Fund (the
"Fund") gained 31.11%, compared with 43.22% for the Standard & Poor's (S&P)
MidCap 400 Index(1) 25.46% for the S&P MidCap Value Index(2) and 13.27% for the
S&P 500 Index(3). The Fund outpaced most of these indexes primarily because we
purchased severely depressed technology and energy stocks in late 1998 and early
1999 and we subsequently had strong appreciation in those stocks. The Fund
underperformed the S&P MidCap 400 Index because it has a larger weighting in
growth stocks.

After six years of underperformance, mid-cap and small-cap stocks outdistanced
large caps during the past 12 months. Additionally, as the performance of
high-momentum growth stocks is waning, investor interest is returning to value
stocks. This observation is buttressed by the historically large valuation
differential that exists between growth and value and between large- and
small-cap stocks. The attractive valuations of smaller stocks have generated a
record level of corporate acquisitions. During the year, about 8% of our
portfolio had acquisitions announced. With the economy and earnings growth
slowing, we believe the risk/reward prospects for our portfolio, which sells at
less than 15 times 2000 estimated earnings and 2.2 times book value, are
considerably better than those of the major market benchmarks.

Period in Review

Over the past six months, we increased our consumer cyclical weighting by adding
new positions in Briggs & Stratton, Tecumseh Products and RPM and registering
substantial appreciation in existing homebuilder stocks. Our new positions sell
at less than 10 times 2000 estimated earnings and 2 times book value, are more
than 40% off their 12-month high prices and have good balance sheets.

Our largest sector weighting has always been financials, and our patience was
well rewarded this year. Insurance stocks had been selling below book value,
but, with an apparent upswing in industry pricing, our three insurance holdings
appreciated more than 40% this year. REITs and brokerage stocks were also
strong, and we used this strength to reduce our holdings.

While technology stocks penalized Fund performance recently, they were positive
over the last 12 months. We have been consistent sellers in this area all year
as many stocks appreciated to what we believed were fully valued levels. Since
the end of March, we eliminated Novellus, Tektronix, Convergys, Complete
Business Solutions, Silicon Graphics and Loral. The first three were up more
than 100% from when we purchased them; we had relatively small losses in the
latter three companies due to fundamental shortfalls. As a result of these
transactions, our technology exposure dropped to its lowest level since the
Fund's inception. Toward the end of the year, with many technology stocks down
more than 50% from their highs and selling at 10 times expected earnings, we
began to reinvest in this area once again. Some of these purchases might be
premature, as they were in 1998 and early 1999, but we believe the long-term
risk/reward relationship is very favorable.

Energy stocks continued to be strong. Because we believe the price of oil has
risen at an unsustainable pace, we also believe risk levels in these stocks have
risen. Therefore, we eliminated our positions in Devon, Nobel and Barrett. We
used some of these sale proceeds to establish a position in USX Marathon Group,
which sells at about 10 times earnings, is up less than 20% this year and has
promising new management.

Among the weakest stocks in the portfolio were the IT staffing companies,
especially Spherion and Computer Horizons. Also down this period were some
consumer stocks such as Federated Department Stores and Hasbro. Although these
companies have had disappointing earnings as a group, they are selling at less
than 10 times estimated 2001 earnings, have good balance sheets and have active
stock buy back programs. Although they have been disappointing, we are
maintaining positions in these stocks.

Summary

Since January, our Fund has had positive returns while major market averages
have declined. We believe this could continue for some time as earnings growth
subsides and historically high valuation differentials compress to more normal
levels. The major risk to mid cap and smaller cap stocks is a
greater-than-projected economic slowdown. However, even in that scenario, we are
more comfortable with smaller value stocks than with much more expensive large
cap growth equities.

We believe mid cap value stocks will continue to benefit as investors redeploy
cash flows away from large cap stocks. We will remain selective in our
investing, taking advantage of opportunities created by temporary dislocations.
With patience, these good quality stocks that are temporarily out of favor
provide the possibility of long-term gain.

Berger Funds o September 30, 2000 Combined Annual Report

Growth Fund                   PORTFOLIO MANAGER COMMENTARY     JAY W. TRACEY III
--------------------------------------------------------------------------------

Performance

The Berger Growth Fund ("the Fund") had a very good fiscal year ended September
30, 2000, gaining 60.93% compared with 13.27% and 33.74% for the Standard &
Poor's (S&P) 500 Index(1) and the Nasdaq Composite Index,(2) respectively. This
solid performance was driven primarily by stock selection, although our
relatively aggressive weighting in technology also helped.

Period in Review

The Fund's technology holdings contributed more than any other sector to the
Fund's good results. The Fund benefited from the performance of companies that
supply infrastructure for the Internet build-out. Component suppliers Applied
Micro Circuits, SDL Inc., Corning and JDS Uniphase and equipment suppliers Cisco
Systems, Juniper Networks and Sycamore Networks all did very well. We remain
bullish on many of the component and equipment companies that are supplying
innovative, market-leading solutions to service providers, which are, in turn,
aggressively deploying those solutions to meet an insatiable demand for
increased bandwidth.

Companies meeting the rapidly growing demand for data storage solutions also
contributed positively to performance, notably EMC Corp., the leader in
enterprise storage systems; Network Appliance, which makes specialized devices
designed to provide file service for data-intensive networks; and Veritas
Software, the leader in data storage management software. The Fund also
benefited from companies supplying leading-edge software solutions that take
advantage of the Internet to deliver competitive advantages to their customers.
Among the better performers were Verisign, which provides digital certificate
services that secure e-commerce and communications over the Internet; Siebel
Systems, the leader in customer relationship management software that automates
corporate sales forces; and Agile Software, whose collaborative software
products help automate commerce between manufacturers and their suppliers and
customers. Surveys of information technology managers at major companies confirm
that e-commerce spending, which has been strong all year, should continue to
grow rapidly for the foreseeable future. We remain, therefore, optimistic about
the outlook for select vendors of e-commerce solutions and view corrections as
buying opportunities.

Elsewhere in technology, semiconductor and semiconductor equipment stocks such
as Intel, Applied Materials, KLA-Tencor and Lam Research, strong early in the
year, weakened considerably in the last few months. We significantly reduced our
exposure to this industry in a timely fashion. Microsoft has been disappointing,
but we continue to hold this leading company in anticipation of accelerating
sales of Windows 2000 next year. Technology is an exciting but risky area in
which to invest because the pace of change is so fast, the market is so
competitive and the stocks are so volatile. Nevertheless, we remain overweighted
in this increasingly important sector, and we will continue to focus on
innovative companies with strong, forward-looking management teams, leading
products or services, defensible barriers to competition and rapidly growing,
sustainable revenues and earnings.

In healthcare, the Fund has benefited from its focus on biotechnology and
selected pharmaceuticals. Fund winners included Genentech, PE Corp.-PE
Biosystems Group, Amgen and American Home Products. Bristol Myers Squibb was our
main disappointment and has been sold. Because of regulatory, reimbursement and
pricing uncertainties, especially as we approach the elections, we have been
underweighted and very selective in the healthcare sector. We are positive on a
long-term basis, however, and favor those companies that have innovative new
products coming onto the market that we believe may generate substantial new
revenue and shareholder value.

Energy services holdings such as ENSCO International and Nabors Industries were
strong, reflecting positive supply/demand fundamentals. Though it is tempting to
take some profits, we have elected to stay with this winning sector because the
earnings outlook is only getting brighter.

Generally, the consumer sector was disappointing. In particular, the Fund's
radio broadcasting stocks were down as advertising revenues slowed over the
latter half of the fiscal year. Although this trend is likely to persist for
another quarter or two, we are holding higher-quality companies such as Clear
Channel Communications and Hispanic Broadcasting, which now offer good value. In
the retail sector, very few companies showed good results, and the Fund's
results, likewise, were mixed. We had some success in Radio Shack, but Best Buy
and Circuit City were disappointing and were sold. In general, retail sales
trends have been lackluster, and we continue to be underweighted in this sector.

Summary

Again, the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our growth-oriented investment philosophy.
Every day presents us with new opportunities in rapidly growing companies.
Rarely have there been so many companies addressing such open-ended business
opportunities as there are today. Regardless of the stock market's short-term
ups and downs, we are excited about the fundamental outlook for the great growth
companies that are leading us into the future, and we will continue to focus on
the best of them.

Performance

The Berger International Fund (the "Fund") gained 9.43% for the year ended
September 30, 2000, compared with the 3.42% gain for its benchmark, the MSCI
EAFE Index.(1)

World equity markets registered exceptional gains toward the end of 1999, fueled
by a combination of low interest rates and rising commodity prices. There was
significant divergence in the performance of those markets in the first part of
2000, however. Half of the markets in the 22 countries that comprise the MSCI
World Index2 registered gains and half of the markets registered losses (as
measured in U.S. dollars). Rising interest rates in all markets except Japan
also served as a drag on returns.

Global markets continued to decline over the last six months, with the majority
of the markets in the MSCI World Index posting negative performance.

The last three months started well with a number of blue-chip European companies
posting better than expected profits for the first half of the year and economic
data revealing stronger-than-expected activity, particularly in the core
European economies. By the end of August, though, the weakness of the Euro
combined with an uptake in commodity prices, particularly energy, was pushing
producer price inflation in the Eurozone higher.

Elsewhere, poor supply-and-demand conditions have contributed to the Japanese
market's malaise this year. The Japanese markets were unable to shrug off
concerns about corporate profit growth that began with several US companies and
quickly rippled around the world. Other Asian markets remained sluggish, despite
good economic indicators in Hong Kong.

Period in Review

For the first six months of the fiscal year, performance was aided by the Fund's
investment in telecommunications, media and technology stocks. But over the last
six months, performance was hurt by these same investments. The most significant
decline came from stocks in the Growth in Telecommunications theme. Telecom
Italia, which had performed well earlier this year, succumbed to the general
sector sentiment and fell sharply during the last three months, despite
reporting earnings in line with market expectations. Koninklijke KPN NV and
Telefonaktiebolaget LM Ericsson were two other holdings that performed well in
the first half of the fiscal year, but took a dive in the second half of the
fiscal year. KPN was dogged by several concerns, including disappointing
earnings news. Ericsson, who holds nearly half of all third-generation mobile
license contracts that have been awarded to date, was hit hard when concerns
emerged that profit margins on these contracts may come under some pressure.

Semiconductor companies were impacted globally as sales of personal computer and
mobile phone handsets slowed. This negatively impacted two Japanese-quoted
companies in the Restructuring Opportunities theme, NEC and Hitachi. Although
neither company is a pure semiconductor play, they were unable to avoid the
sector's general downturn despite significant earnings upgrades announced by
both companies in September.

On a more upbeat note, stocks in the Asian Cyclical Recovery theme performed
well, led by Hong Kong-quoted companies. Competition has reduced mortgage costs
in Hong Kong over the past two years, and residential property prices and
transaction volumes are rising. Cheung Kong and Sun Hung Kai Properties, among
the region's largest property developers, were beneficiaries of this trend.

Stocks in the Growth in Healthcare Needs theme were positive most of the year,
particularly pharmaceutical stocks such as AstraZeneca, the UK pharmaceutical
company, and Glaxo Wellcome. Despite continued regulatory delays in its proposed
merger, Glaxo Wellcome was boosted by an increase in sales and profits.

Summary

Technology stocks continue to weaken relative to broader market indices, as
investors become increasingly more discriminating in selecting stocks in this
sector. The euphoria of last year has disappeared, and bankruptcies are
increasing as the availability of new capital is restricted to the more viable
enterprises. We welcome this development as a return to rationality, and we
continue to expect a consequent broadening of market performance.

The positive aspect of an economic slowdown is a more benign outlook for
interest rates. The greatest threat to this outlook comes from oil prices. To
date, oil prices have not fed through to any significant extent into broad
measures of inflation. But, if prices persist at current levels and threaten to
feed into wage rates, the outlook for interest rates would deteriorate. On
balance, we do not anticipate that this will occur; however, it does represent a
potential threat to equity and bond markets.

Performance figures are historical and, in part, reflect the performance of a
pool of assets advised by BIAM (Bank of Ireland Asset Management) for periods
before the Fund commenced operations on November 7, 1996, adjusted to reflect
any increased expenses associated with operating the Fund. The asset pool was
not registered with the Securities and Exchange Commission and therefore was not
subject to the investment restrictions imposed by law on registered mutual
funds. If the pool had been registered, its performance might have been
adversely affected. Investments in the Fund are not insured by the Federal
Deposit Insurance Corporation, are not deposits and are not obligations of, or
endorsed or guaranteed in any way by, any bank. Past performance is no guarantee
of future results. Fund performance shown reflects the unusually favorable
market conditions that existed in 1999 which likely are not sustainable as
market conditions change. Investment return and principal value will fluctuate
so that shares, when redeemed, may be worth more or less than their original
cost.

--------------------------------------------------------------------------------

Performance

The Berger Growth and Income Fund (the "Fund") had an exceptional year, gaining
56.09% for the year ended September 30, 2000, versus 13.27% for the Standard &
Poor's (S&P) 500 Index.1 The fact that the Fund significantly outperformed its
benchmark can be attributed to two factors--our rigorous stock selection process
and our concentration on high-quality, large-capitalization stocks with
excellent growth prospects. The Fund stayed focused all year on what we believed
were the best-positioned companies in sectors with strong growth outlooks,
especially technology, communications and energy. We remained underweighted in
more competitive, slower-growth sectors such as basic industries, capital goods
and transportation.

Period in Review

Technology, the sector in which we see the best long-term growth prospects,
continued to be the Fund's largest weighting. We recognized that Corning, Nortel
and Juniper would benefit from strong demand for bandwidth and build-out of
communications infrastructure. This build-out is being driven by consumer use of
the Internet and the demand for high bandwidth applications. Similarly, we
believe that Nokia, the leading provider of handsets, and Qwest, which has the
most complete fiber-optic network, will receive a boost from the same trends.

In other areas of technology, the Fund substantially benefited from its position
in storage companies, which, in turn, are riding the tide of growth in data
storage needs created by the burgeoning information revolution. We positioned
the Fund in leading storage companies, including EMC Corp., Network Appliance
and Veritas Software. Our holdings in semiconductor companies that serve growing
communications markets, such as Applied Micro Circuits and STMicroelectronics,
also contributed positively to the performance of the Fund this year.

Compared with the index, the Fund is overweighted in the energy sector, which is
not typical in a growth and income fund. This serves as a good counterbalance to
our technology holdings. We have positioned our energy holdings primarily in
service companies that not only can benefit from the strong supply
characteristics in the oil and natural gas markets, but that also can gain
market share and grow faster than competitors. Two of these companies, Enron and
ENSCO International, were the largest contributors to Fund performance in this
sector.

Prudent stock picking in healthcare and financial services also contributed to
the Fund's strong performance over the year. Genentech and Amgen were our
largest and best-performing healthcare holdings, reflecting both companies'
continued rollout of new and exciting products. Among financial stocks, we
continue to see more growth in capital market plays such as Schwab and Morgan
Stanley Dean Witter than in traditional banking franchises, which have been
slowed by the Federal Reserve Board's repeated interest rate increases.

On the downside, several of our retail and consumer stocks turned in
disappointing results. Among retailers, both Best Buy and Gap declined. We
believe Gap's issues will be difficult to overcome in the short term, so we
eliminated our position in this stock. We continue to hold Best Buy, however,
because we believe the company is well-positioned to benefit from consumer
electronics spending over the holiday season. Radio stocks such as Hispanic
Broadcasting underperformed because of a slowing in advertising revenues, and we
sold our position because we believed there were better uses for the Fund's
assets.

In the beginning of the year, the Fund benefited from positions in several
Japanese multinational companies such as Toyota and Sony. We took profits in the
stocks during the year and redeployed the proceeds into companies we are able to
monitor more closely through frequent management contacts.

Summary

Again the Fund's good results were driven more by individual stock selection
than by the weighting given to various sectors. Because we employ a
fundamentally research-driven, bottom-up approach to portfolio management, the
Fund's results are consistent with our growth-oriented investment philosophy.
Every day presents us with new opportunities in leading companies. Rarely have
so many blue-chip companies addressed such growth opportunities as they do
today. Regardless of the stock market's short-term ups and downs, we are excited
about the fundamental outlook for the great growth companies that are leading us
into the future, and we will continue to focus on the best of them.

Balanced Fund                 PORTFOLIO MANAGER COMMENTARY      STEVEN L. FOSSEL
--------------------------------------------------------------------------------

Performance

The Berger Balanced Fund (the "Fund") had another year of strong performance,
gaining 30.08% for the year ended September 30, 2000, versus 13.27% for the
Standard & Poor's (S&P) 500 Index.1 The Fund was able to outperform the S&P 500
Index even though we invest in a balance of equity and fixed-income securities.

As of September 30, 2000, the Fund was invested 63% in equities, 35% in fixed
income and 2% in cash. Compared with a year ago, this represents an increase in
the equity portion of the Fund and a decrease in cash. Market volatility
prompted these changes as it created opportunities to put cash to work in
selected high-quality growth companies priced at reasonable valuations.

Period in Review

We believe that the Fund's solid outperformance can be accounted for by prudent
stock-picking rather than by large sector betting. In keeping with our growth
philosophy, we were overweighted in technology this year and held a number of
the top-performing stocks in this sector. We recognized that Corning and Qwest
Communications International would benefit from strong demand for bandwidth and
similarly, that semiconductor chip and wireless handset manufacturers such as
QUALCOMM would receive a boost from strength in their end markets. Oracle, a
leading enterprise software company, was aided by growth in corporate
information management needs and accordingly was one of the top contributors to
the Fund's performance over the year.

Energy was another area of emphasis for the Fund. We believe that the tight
supply and demand situation for oil and natural gas will continue to create
opportunities for the best-positioned companies in this sector. Two of those
companies, Enron and Transocean Sedco Forex, Inc., contributed strongly to the
Fund's gain this year.

In both the healthcare and financial services sectors, the Fund benefited from
careful stock-picking despite our underweighting in these areas over the year.
Genentech was our largest and best-performing healthcare holding, reflecting the
continued rollout of new and exciting products. Among financial stocks, we
continue to see more growth in capital market plays such as Citigroup and Morgan
Stanley Dean Witter than in traditional banking franchises, which have been
slowed by the Federal Reserve Board's repeated interest rate increases.

On the downside, several of our retail and consumer stocks turned in
disappointing results. Among retailers, Nordstrom and Gap made merchandising
blunders that were not easily correctable, and we eliminated them from the
portfolio. Among consumer companies, Procter & Gamble and Dial experienced
slowing growth and were also sold during the year.

The fixed-income portion of the Fund continues to be positioned conservatively
to provide income and reduce risk and volatility in the overall portfolio. The
average duration and maturity remains relatively short--about three years.
Agency securities make up nearly half of the Fund's fixed-income holdings and
the other half is concentrated in investment-grade corporate bonds and U.S.
Treasury securities.

Summary

We believe the fixed-income portion of the portfolio will continue to provide
both stability and income, while the equity portion will focus on high-quality
growth investments. Strong gains on the equity side of the portfolio produced
most of the Fund's solid total return for the year. These results were driven
more by individual stock selection than by the weighting given to various
sectors. Because we employ a fundamentally research-driven, bottom-up approach
to portfolio management, the Fund's results are consistent with our
growth-oriented investment philosophy. Every day presents us with new
opportunities in high-quality companies. Rarely have there been so many
companies addressing growth opportunities as there are today. Regardless of the
stock market's short-term ups and downs, we are excited about the fundamental
outlook for blue-chip companies that are leading us into the future, and we will
continue to focus on the best of them.

Past performance is no guarantee of future results. Fund performance shown
reflects the unusually favorable market conditions that existed in 1999 which
likely are not sustainable as market conditions change. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. Life of Fund performance includes returns for
the last quarter of 1997, which reflect a higher-than-normal level of trading
activity undertaken to pursue equity opportunities available as the Advisor was
beginning to implement the Fund's long-term approach to equity management.

shares of InfoTech were designated Institutional Shares ("TECH; Inst") and a
separate class of shares, Investor Shares ("TECH; Inv"), was offered. BNG, BSCG
and BSCV each also offer two separate classes of shares; Investor Shares ("BNG;
Inv", "BSCG; Inv", and "BSCV; Inv", respectively) and Institutional Shares
("BNG; Inst", "BSCG; Inst", and "BSCV; Inst", respectively). Both classes of
each Fund have identical rights to earnings, assets and voting privileges. BNG;
Inst and BSCG; Inst commenced operations on August 16, 1999 and October 16,
1999, respectively.

BBIF is one of three series established under the Berger Worldwide Funds Trust
("BBWF Trust") (formerly the Berger/BIAM Worldwide Funds Trust), a Delaware
business trust.

BBIF invests all of its investable assets in the Berger International Portfolio
(the "Portfolio"), a series of Berger Worldwide Portfolios Trust ("BBWP Trust").
The value of such investment reflects BBIF's proportionate interest in the net
assets of the Portfolio (12% at September 30, 2000). The Portfolio is an
open-end management investment company and has the same investment objective and
policies as BBIF. The performance of BBIF will be derived from the investment
performance of the Portfolio. The financial statements of the Portfolio,
including the schedule of investments, are included elsewhere in this report and
should be read in conjunction with BBIF's financial statements.

On January 19, 2000, Berger LLC ("Berger") and Bank of Ireland Asset Management
(U.S.) Limited ("BIAM") entered into an agreement to dissolve BBOI Worldwide LLC
("BBOI"), the former advisor to the Portfolio. This agreement was approved by
shareholders on May 5, 2000. Upon approval of the new management agreement,
Berger became the Fund's advisor and BIAM continues to be responsible for the
day-to-day management of the Fund's portfolio as sub-advisor. The dissolution of
BBOI had no effect on the investment advisory services to or on the fees borne
by BBIF for advisory services. Additionally, BBIF was renamed Berger
International Fund and the Berger/BIAM Worldwide Funds Trust was renamed Berger
Worldwide Funds Trust.

Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by the Funds in the preparation of their financial statements. The
policies are in conformity with generally accepted accounting principles.

Investment Valuation

Securities are valued at the close of the regular trading session of the New
York Stock Exchange (the "Exchange") on each day that the Exchange is open.
Securities listed on national exchanges, the Nasdaq Stock Market and foreign
exchanges are valued at the last sale price on such markets, or, if no last sale
price is available, they are valued using the mean between their current bid and
ask prices. Prices of foreign securities are converted to U.S. dollars using
exchange rates determined prior to the close of the Exchange. Securities traded
in the over-the-counter market are valued at the mean between their current bid
and ask prices. Short-term obligations maturing within sixty days are valued at
amortized cost, which approximates market value. Securities for which quotations
are not readily available are valued at fair values as determined in good faith
pursuant to consistently applied procedures established by the
directors/trustees of the Funds.

Generally, trading in foreign securities markets is substantially completed each
day at various times prior to the close of the Exchange. The values of foreign
securities used in computing the Funds' net asset values are determined as of
the earlier of such market close or the closing time of

--------------------------------------------------------------------------------

the Exchange. Occasionally, events affecting the value of such securities may
occur between the times at which they are determined and the close of the
Exchange, or when the foreign market on which such securities trade is closed
but the Exchange is open, which will not be reflected in the computation of net
asset value. If during such periods, events occur that materially affect the
value of such securities, the securities will be valued at their fair market
value as determined in good faith pursuant to consistently applied procedures
established by the directors/trustees of the Funds.

Since BBIF invests all of its investable assets in the Portfolio, the value of
BBIF's investable assets will be equal to the value of its beneficial interest
in the Portfolio. Valuation of securities by the Portfolio is discussed in Note
1 of the Portfolio's Notes to Financial Statements, which are included elsewhere
in this report.

Calculation Of Net Asset Value

Each Fund's per share calculation of net asset value for each share class is
determined by dividing the net assets applicable to each share class by the
total number of shares outstanding for that class.

Federal Income Tax Status

It is the Funds' policy to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of their
taxable income to shareholders. Therefore, no income tax provision is required.

Foreign Currency Translation

Assets and liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars at the prevailing market rates as quoted by one or
more banks or dealers on the date of valuation. The cost of securities is
translated into U.S. dollars at the rates of exchange prevailing when such
securities were acquired. Income and expenses are translated into U.S. dollars
at rates of exchange prevailing when accrued.

Investment Transactions And Investment Income

Investment transactions are accounted for on the date investments are purchased
or sold. Dividend income is recorded on the ex-dividend date except that certain
dividends from foreign securities are recorded as soon as a Fund is informed of
the ex-dividend date if such information is obtained subsequent to the
ex-dividend date. Dividend income is recorded net of foreign taxes withheld.
Interest income is recorded on the accrual basis and includes accretion of
discount. Gains and losses are computed on the identified cost basis for both
financial statement and federal income tax purposes for all securities.

Allocation Of Income, Expenses And Gains And Losses

Income, expenses (other than those attributable to a specific share class) and
gains and losses of TECH, BNG, BSCG and BSCV are allocated daily to each class
of shares based upon the ratio of net assets represented by each class as a
percentage of total net assets of each of the aforementioned Funds. Expenses
directly attributable to a specific class of shares are charged against the
operations of such class.

As an investor in the Portfolio, BBIF is allocated its pro rata share of the
aggregate investment income, realized and unrealized gains or losses and annual
operating expenses of the Portfolio. Income, realized and unrealized gains or
losses and expenses are allocated on the day incurred in proportion to the prior
day's net assets of BBIF relative to the other investors in the Portfolio.
Expenses directly attributable to BBIF are charged against the operations of the
Fund.

Common Expenses

Certain expenses, which are not directly allocable to a specific Fund, are
allocated to each of the Funds on the basis of relative net assets.

Organization Costs

Expenses incurred in connection with the organization of TECH are being
amortized over sixty months from April 8, 1997, the commencement of investment
operations of TECH.

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 reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Actual results may differ from those estimates.

Berger Funds o September 30, 2000 Combined Annual Report

Notes to Financial
Statements
September 30, 2000
--------------------------------------------------------------------------------

2. Agreements

Berger serves as investment advisor to TECH, BNG, BSEL, BSCG, BSCV, BMCG, BMCV,
Growth, BG&I and BBAL pursuant to agreements that provide for an investment
advisory fee to be paid to Berger according to the following schedule:

<TABLE>
<CAPTION>
                             Average Daily
Fund                            Net Assets    Annual Rate
----                    ------------------    -----------
<S>                     <C>                   <C>
BSEL, BMCG, BMCV,       First $500 million           .75%
Growth, BG&I            Next $500 million            .70%
                        Over $1 billion              .65%

TECH, BNG,              First $500 million           .85%
BSCG, BSCV              Next $500 million            .80%
                        Over $1 billion              .75%

BBAL                    First $1 billion             .70%
                        Over $1 billion              .65%
</TABLE>

All investment advisory fees are accrued daily and paid monthly. Berger has
delegated the day-to-day investment management of BSCV and BMCV to Perkins,
Wolf, McDonnell & Company ("PWM"). Additionally, Berger has delegated the
day-to-day investment management of TECH to Bay Isle Financial Corporation
("BIFC"). Berger pays PWM and BIFC sub-advisory fees from the investment
advisory fee it receives from BSCV, BMCV and TECH.

Berger has agreed to reimburse BNG; Inst and BSCG; Inst to the extent that each
class' transfer agency and registration fees, in aggregate, exceed .20% of the
class' average daily net assets in any fiscal year.

The Funds (excluding BBIF) have entered into administrative services agreements
with Berger. Berger currently provides administrative services to the Funds at
no cost.

Pursuant to an Administrative Services Agreement, whereby Berger serves as the
administrator to BBIF, BBIF pays Berger a fee at an annual rate equal to the
lesser of 0.45% of its average daily net assets or Berger's annual cost to
provide or procure such services plus 0.02% of BBIF's average daily net assets.
Under the Agreement, Berger is responsible at its own expense, for providing or
procuring administrative services reasonably necessary for the operation of
BBIF, excluding legal and registration fees.

The Funds have adopted plans pursuant to Rule 12b-1 under the 1940 Act (the
"Plans"). The TECH, BNG, BSCG and BSCV Plans apply only to the Investor Shares
class of each Fund. The Plans provide for the payment to Berger of a 12b-1 fee
of .25% per annum of each Fund's average daily net assets (or the net assets of
a particular class of shares, where applicable) to finance activities primarily
intended to result in the sale of Fund shares. The Plans provide that such
payments will be made to Berger as compensation rather than as reimbursements
for actual expenses incurred to promote the sale of shares of the Funds.

The Funds (except BBIF) have also entered into recordkeeping and pricing
agreements with State Street Bank and Trust Company ("State Street"), which also
serves as the Funds' custodian. The recordkeeping and pricing agreements provide
for the monthly payment of a base fee plus a fee computed as a percentage of
average daily net assets on a total relationship basis with other Berger Funds.
State Street's fees for custody, recordkeeping and pricing are subject to
reduction by credits earned by each Fund, based on the cash balances of each
Fund held by State Street as custodian.

DST Systems, Inc. ("DST"), an affiliate of Berger through a degree of common
ownership, provides shareholder accounting services to the Funds. DST
Securities, Inc., a wholly-owned subsidiary of DST, is designated as an
introductory broker on certain portfolio transactions. The Funds receive an
amount equal to the brokerage commissions paid to DST Securities, Inc. as
credits against transfer agent fees and expenses. Such credits are presented as
fees paid indirectly on the Statement of Operations. For the year ended
September 30, 2000, the following Funds earned such credits:

<TABLE>

BBAL                                          6,318
</TABLE>

Certain officers and/or directors of Berger are also officers and/or
directors/trustees of the Funds. Directors/Trustees who are not affiliated with
Berger are compensated for their services according to a fee schedule, allocated
among the entire Berger Funds complex, which includes an annual fee component
and a per meeting fee component. For the year ended September 30, 2000, such
directors'/trustees' fees and expenses totaled $331,788 for the Funds.

The Funds (except BBIF) adopted a director/trustee fee deferral plan (the
"Plan") which allows the non-affiliated directors/trustees to defer the receipt
of all or a portion of the directors'/trustees' fees payable. The deferred fees
are invested in various funds advised by Berger until distribution in accordance
with the Plan.

Futures and  Forward Contracts

Each Fund may hold certain types of forward foreign currency exchange contracts
and/or futures contracts for the purpose of hedging each portfolio against
exposure to market value fluctuations. The use of such instruments may involve
certain risks as a result of unanticipated movements in the market, a lack of
correlation between the value of such instruments and the assets being hedged,
or unexpected adverse price movements. In addition, there can be no assurance
that a liquid secondary market will exist for the instrument. Upon entering a
futures contract, a Fund deposits and maintains as collateral such initial
margin as may be required by the exchanges on which the transaction is affected.
Pursuant to the contracts, a Fund agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in the value of the contract.
Realized and unrealized gains or losses on forward foreign currency contracts
are included in Net Realized and Unrealized Gain (Loss) on Securities and
Foreign Currency Transactions in the Statement of Operations. At September 30,
2000, the Funds had no outstanding futures or forward currency contracts.

Securities Lending

Under an agreement with State Street, TECH, BNG, BSEL, BSCG, BMCG, BMCV, BBAL
and the Portfolio have the ability to lend securities to brokers, dealers and
other authorized financial institutions. Loans of portfolio securities are
collateralized by cash remitted from the borrower of such securities in an
amount equal to at least 102% of the market value of the loaned securities at
the time the loan is made. The cash collateral received is invested in a money
market fund and is evaluated daily to ensure that its market value exceeds the
current market value of the loaned securities. Income generated by such
investment, net of any rebates paid to the borrower, is split among the Fund and
State Street, as lending agent.

At September 30, 2000, the Funds had securities on loan with the following
market values:

--------------------------------------------------------------------------------

Repurchase Agreements

Repurchase agreements held by a Fund are fully collateralized by U.S. government
or government agency securities and such collateral is in the possession of the
Fund's custodian. The collateral is evaluated daily to ensure its market value
exceeds the current market value of the repurchase agreements including accrued
interest. In the event of default on the obligation to repurchase, the Fund has
the right to liquidate the collateral and apply the proceeds in satisfaction of
the obligation. In the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral or proceeds may be
subject to legal proceedings.

Concentration of Risk

The Funds may have elements of risk due to concentrated investments in specific
industries or foreign issuers located in a specific country. Such concentrations
may subject the Fund to additional risk resulting from future political or
economic conditions and/or possible impositions of adverse foreign governmental
laws or currency exchange restrictions. Net Realized and Unrealized Gain (Loss)
on Securities and Foreign Currency Transactions in the Statement of Operations
includes fluctuations from currency exchange rates and fluctuations in market
value.

Federal Income Taxes

Dividends paid by the Funds from net investment income and distributions of net
realized short-term capital gains are, for federal income tax purposes, taxable
as ordinary income to shareholders. For the fiscal year ended September 30,
2000, 1%, 56%, 1%, 17%, 5%, and 2% of the ordinary income distributions declared
by BSEL, BSCV, BMCG, BMCV, BG&I and BBAL, respectively, qualified for the
dividends received deduction available to corporate shareholders.

For the fiscal year or period ended September 30, 2000, the following
percentages of capital gain distributions were considered long-term capital
gains:

BBIF                                             --
</TABLE>

The Funds distribute net realized capital gains, if any, to their shareholders
at least annually, if not offset by capital loss carryovers. Income
distributions and capital gain distributions are determined in accordance with
income tax regulations, which may differ from generally accepted accounting
principles. These differences are primarily due to the differing treatment of
net operating losses, foreign currency and tax allocations. Accordingly, these
permanent differences in the character of income and distributions between

Interest, based on the Federal Funds Rate, is charged to the specific party that
executes the borrowing. In addition, the unsecured line of credit requires a
quarterly payment of a commitment fee based on the average daily unused portion
of the line of credit. No Funds had line of credit borrowings outstanding at

Berger Funds o September 30, 2000 Combined Annual Report

Notes to Financial
Statements
September 30, 2000
--------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Organization

The Berger International Portfolio (the "Portfolio") is registered under the
Investment Company Act of 1940, as amended, as a diversified open-end management
investment company. The Portfolio is a series of the Berger Worldwide Portfolios
Trust (the "Trust"), which was organized as a Delaware business trust on May 31,
1996. Currently there are three investors in the Portfolio: the Berger
International Fund, the International Equity Fund and the Berger International
CORE Fund.

On January 19, 2000, Berger LLC ("Berger") and Bank of Ireland Asset Management
(U.S.) Limited ("BIAM") entered into an agreement to dissolve BBOI. This
agreement was approved by shareholders on May 5, 2000. The dissolution of BBOI
had no effect on the investment advisory services provided to the Portfolio.
Upon approval of the new management agreement, Berger became the Portfolio's
advisor and BIAM continues to be responsible for the day-to-day management of
the Portfolio's investments as sub-advisor. In connection with the dissolution,
the Portfolio was renamed Berger International Portfolio from Berger/BIAM
International Portfolio. Additionally, the Trust was renamed Berger Worldwide
Portfolios Trust from Berger/BIAM Worldwide Portfolios Trust.

Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by the Portfolio in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles.

Investment Valuation

Securities are valued at the close of the regular trading session of the New
York Stock Exchange (the "Exchange") on each day that the Exchange is open.
Securities listed on national exchanges, the Nasdaq Stock Market and foreign
exchanges are valued at the last sale price on such markets, or, if no last sale
price is available, they are valued using the mean between their current bid and
ask prices. Prices of foreign securities are converted to U.S. dollars using
exchange rates determined prior to the close of the Exchange. Securities traded
in the over-the-counter market are valued at the mean between their current bid
and ask prices. Short-term obligations maturing within sixty days are valued at
amortized cost, which approximates market value. Securities for which quotations
are not readily available are valued at fair values as determined in good faith
pursuant to consistently applied procedures established by the trustees of the
Portfolio.

Generally, trading in foreign securities markets is substantially completed each
day at various times prior to the close of the Exchange. The values of foreign
securities are determined as of the earlier of such market close or the closing
time of the Exchange. Occasionally, events affecting the value of such
securities may occur between the times at which they are determined and the
close of the Exchange, or when the foreign market on which such securities trade
is closed but the Exchange is open. If during such periods, events occur that
materially affect the value of such securities, the securities will be valued at
their fair market value as determined in good faith pursuant to consistently
applied procedures established by the trustees of the Portfolio.

Foreign Currency Translation

Assets and liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars at the prevailing market rates as quoted by one or
more banks or dealers on the date of valuation. The cost of securities is
translated into U.S. dollars at the rates of exchange prevailing when such
securities were acquired. Income and expenses are translated into U.S. dollars
at rates of exchange prevailing when accrued.

Federal Income Taxes

The Portfolio is considered a partnership for federal income tax purposes. As
such, each investor in the Portfolio will be taxed on its share of the
Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Sub-Chapter M of the
Internal Revenue Code.

Investment Transactions And Investment Income

Investment transactions are accounted for on the date investments are purchased
or sold. Dividend income is recorded on the ex-dividend date except that certain
dividends from foreign securities are reported as soon as the Portfolio is
informed of the ex-dividend date if such information is obtained subsequent to
the ex-dividend date. Dividend income is recorded net of foreign taxes withheld.
Interest income is recorded on the accrual basis and includes accretion of
discount. Gains and losses are computed on the identified cost basis for both
financial statement and federal income tax purposes for all securities.

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 reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Actual results may differ from those estimates.

2. Agreements

BBOI, prior to its dissolution, rendered investment advisory services to the
Portfolio pursuant to an agreement that provided for an investment advisory fee
to be paid to BBOI at the annual rate of .90% of the Portfolio's average daily
net assets. Effective May 12, 2000 in connection with the dissolution of BBOI,
investment advisory fees charged to the Portfolio by Berger were reduced
according to the following schedule: Average Daily Net Assets Annual Rate

<TABLE>
<CAPTION>
  Average Daily
    Net Assets                           Annual Rate
  -------------                          -----------
<S>                                          <C>
First $500 million                           .85%
Next $500 million                            .80%
Over $1 billion                              .75%
</TABLE>


Berger pays BIAM a sub-advisory fee from the investment advisory fee it receives
from the Portfolio. Berger is also responsible for providing for or arranging
for all managerial and administrative services necessary for the operations of
the Portfolio.

                        Berger Funds o September 30, 2000 Combined Annual Report
--------------------------------------------------------------------------------

The Portfolio has entered into recordkeeping and pricing agreements with State
Street Bank and Trust Company ("State Street"), which also serves as the
Portfolio's custodian. The recordkeeping and pricing agreements provide for the
monthly payment of a base fee plus a fee computed as a percentage of average
daily net assets on a total relationship basis with other funds in the Berger
Funds complex. State Street's fees for custody, recordkeeping and pricing are
subject to reduction by credits earned by the Portfolio, based on the cash
balances of the Portfolio held by State Street as custodian.

Certain officers and trustees of the Trust are officers and directors of Berger.
Trustees who are not affiliated with Berger are compensated for their services
according to a fee schedule, allocated among all of the funds in the Berger
Funds complex, which includes an annual fee component and a per meeting
component. The Portfolio's portion of the trustees' fees and expenses for the
year ended September 30, 2000, totaled $17,890.

The Trust adopted a Trustee Fee Deferral Plan (the "Plan") which allows the
non-affiliated trustees to defer the receipt of all or a portion of the trustee
fees payable. The deferred fees are invested in various funds managed by Berger
until distribution in accordance with the Plan.

3. Investment Transactions

Purchases And Sales

Purchases and sales proceeds of investment securities (excluding short-term
securities) during the year ended September 30, 2000 were as follows:

$256,740,056       $    61,913,161      $    (13,957,463)       $ 47,955,698
</TABLE>


Forward Currency Contracts

The Portfolio may enter into forward foreign currency exchange contracts for the
purpose of hedging the Portfolio against exposure to market value fluctuations
in foreign currencies. The use of such instruments may involve risks such as the
possibility of illiquid markets or imperfect correlation between the value of
the contracts and the underlying securities, or that the counterparty will fail
to perform its obligations. Forward currency contracts and foreign denominated
assets may involve more risks than domestic transactions, including currency
risk, political and economic risk, regulatory risk and market risk. Risk may
arise from the potential inability of a counterparty to meet the terms of a
contract and from unanticipated movements in the value of foreign currencies
relative to the U.S. dollar. The forward foreign currency exchange contracts are
adjusted to the daily exchange rate of the underlying currency and any gains or
losses are recorded for financial statement purposes as unrealized gains or
losses until the contract settlement date. Realized and unrealized gains or
losses on these securities are included in Net Realized and Unrealized Gain
(Loss) on Securities and Foreign Currency Transactions in the Statement of
Operations.

Securities Lending

Under an agreement with State Street, the Portfolio has the ability to lend
securities to brokers, dealers and other authorized financial institutions.
Loans of portfolio securities are collateralized by cash remitted from the
borrower of such securities in an amount equal to at least 102% of the market
value of the loaned securities at the time the loan is made. The cash collateral
received is invested in a money market fund and is evaluated daily to ensure
that its market value exceeds the current market value of the loaned securities.
Income generated by such investment, net of any rebates paid to the borrower, is
split among the Portfolio and State Street as lending agent. At September 30,
2000, the Portfolio had securities on loan with a market value of $25,904,366.

Repurchase Agreements

Repurchase agreements held by the Portfolio are fully collateralized by U.S.
government and government agency securities and such collateral is in the
possession of the Portfolio's custodian. The collateral is evaluated daily to
ensure its market value exceeds the current market value of the repurchase
agreements including accrued interest. In the event of default on the obligation
to repurchase, the Portfolio has the right to liquidate the collateral and apply
the proceeds in satisfaction of the obligation. In the event of default or
bankruptcy by the other party to the agreement, realization and/or retention of
the collateral or proceeds may be subject to legal proceedings.

Concentration of Risk

The Portfolio may have elements of risk due to concentrated investments in
specific industries or foreign issuers located in a specific country. Such
concentrations may subject the Portfolio to additional risk resulting from
future political or economic conditions and/or possible impositions of adverse
foreign governmental laws or currency exchange restrictions. Net Realized and
Unrealized Gain (Loss) on Securities and Foreign Currency Transactions in the
Statement of Operations includes fluctuations from currency exchange rates and
fluctuations in market value of securities.

4.  Line of Credit

The Portfolio, along with certain other funds managed by Berger, is party to an
ongoing agreement with certain banks that allows these funds and the Portfolio,
collectively, to borrow up to $150 million, subject to certain conditions, for
temporary or emergency purposes. Interest, based on the Federal Funds Rate, is
charged to the specific party that executes the borrowing. In addition, the
unsecured line of credit requires a quarterly payment of a commitment fee based
on the average daily unused portion of the line of credit. At September 30,
2000, the Portfolio had no borrowings outstanding on the line of credit.

Berger Funds o September 30, 2000 Combined Annual Report

Report of Independent
Accountants
--------------------------------------------------------------------------------

To the Boards of Directors/Trustees and Shareholders of Berger Growth Fund,
Inc., Berger Growth and Income Fund, Inc., Berger Omni Investment Trust, Berger
Investment Portfolio Trust and Berger Worldwide Funds Trust, and to the Board of
Trustees and Investors of Berger Worldwide Portfolios Trust

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights or ratios/supplementary data,
as applicable, present fairly, in all material respects, the financial position
of Berger Growth Fund, Inc. (formerly Berger One Hundred Fund, Inc.), Berger
Growth and Income Fund, Inc., Berger Small Cap Value Fund (the sole fund
comprising Berger Omni Investment Trust), Berger Information Technology Fund,
Berger New Generation Fund, Berger Select Fund, Berger Small Company Growth
Fund, Berger Mid Cap Growth Fund, Berger Mid Cap Value Fund, and Berger Balanced
Fund (constituting Berger Investment Portfolio Trust), Berger International Fund
(formerly Berger/BIAM International Fund; one of the funds constituting Berger
Worldwide Funds Trust formerly Berger/BIAM Worldwide Funds Trust) and Berger
International Portfolio (formerly Berger/BIAM International Portfolio; the sole
portfolio comprising Berger Worldwide Portfolios Trust formerly Berger/BIAM
Worldwide Portfolios Trust) (collectively the "Funds") at September 30, 2000,
the results of each of their operations for the year then ended, the changes in
each of their net assets for each of the periods indicated and the financial
highlights or ratios/supplementary data for each of the periods indicated, in
conformity with accounting principles generally accepted in the United States of
America. These financial statements and financial highlights or
ratios/supplementary data (hereafter referred to as "financial statements") are
the responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
September 30, 2000 by correspondence with the custodian and brokers, provide a
reasonable basis for our opinion. The financial statements of The Omni
Investment Fund (now known as Berger Omni Investment Trust) and InformationTech
100 Fund (now known as Berger Information Technology Fund) for the years ended
December 31, 1996 and February 28, 1999, respectively, were audited by other
independent accountants whose reports dated January 24, 1997 and March 26, 1999,
respectively, expressed unqualified opinions on those financial statements.
