Berger Funds o March 31, 2000 Combined Semi-Annual Report

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

Dear Berger Investor:

Investors have enjoyed extraordinary times over the last few years. In fact,
last year a record number of mutual fund investors saw stellar performance that
could well have been a once in a lifetime experience. More recently, however,
we've had a strong dose of market volatility. The spring of 2000 has been marked
by steep dives and dizzying ascents that could leave even experienced investors
a little unsettled. While this semiannual report is required to discuss the
six-month period ended March 31, I'd also like to offer a little perspective on
April's events.

Through the end of March, nine of eleven Berger Funds outpaced their benchmarks.
Clearly market conditions had for some time favored the growth investors, and
results for Berger Funds demonstrate that. Berger's New Generation, Select,
Small Company Growth, Mid Cap Growth, Information Technology, Growth, Growth and
Income, and Balanced Funds continued the excellent performance they demonstrated
in 1999. Our value funds, Small Cap and Mid Cap and International, showed
smaller gains. The International Fund topped the EAFE Index,(1) while the other
two beat their value benchmarks but lagged the broader Russell 2000(1) and
Standard & Poor's Mid Cap 400(1) indices.

As all investors are aware, the picture has changed. The huge gap between the
old economy stocks represented by the blue chips and the technology stocks of
the new economy had to narrow. Enter the correction.

It's been a bumpy ride, but our investment team believes the correction has been
necessary to shake out excesses in the market and will be healthy over the long
term. Berger's portfolio managers and analysts remain confident in the
fundamentals of the companies held in the Funds and have taken advantage of this
opportunity to buy quality companies at the most reasonable valuations seen in
some time.

Despite the market's severe "mood swings" and the belief that continued
volatility should be expected, our investment team remains optimistic about the
long-term prospects for the stock market.

I encourage you to call Investor Services at (800) 551-5849 or visit our Web
site at bergerfunds.com for performance information that reflects current
events. I also encourage you to read the semiannual commentaries by each
portfolio manager that appear later in this report.

The market's dramatic moves have been enough to leave even the most committed
long-term investors a little weak in the knees, but keep the following in mind:

o Our domestic economy is very healthy.

o The market seems comfortable with the actions of the Federal Reserve even
though additional interest rate hikes remain possible.

o The most recent earnings reports were very strong overall.

One of the most important things we as investors can do now is to maintain
realistic expectations. History tells us it would be a mistake to look for
exceptional double- and even triple-digit returns to continue. As investors we
should expect annual returns more in line with the long-term historical return
of 12%.

                       Berger Funds o March 31, 2000 Combined Semi-Annual Report

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

Other basics to keep in mind include:

o Know yourself. Risk is inherent in the stock market. It's important to
understand the relationship between risk and reward. Ask yourself how much risk
are you really able to tolerate. Find your comfort zone.

o Keep short-term market moves in perspective. Trying to "time" the market is
extremely risky.

o Invest for the long term. Although individual stocks generally are more
volatile, the long-term trend of the stock market has been to outperform other
types of investments. Historically the stock market spends more time going up
than down. Successful investors are patient.

o Invest regularly. As a committed long-term investor, dollar cost averaging can
help you accumulate shares with less price risk than buying a large block of
shares all at once.(2)

o Diversify your holdings. The market tends to favor or punish certain sectors
at various times. To reduce your overall portfolio volatility, you might divide
your investments across market capitalizations, put some money into an
international fund, and invest in both value and growth funds.

Regardless of the twists and turns the market may take, at Berger we remain
focused on our goal of producing consistently competitive performance over time
in every Berger Fund. We are in the process of building a cohesive investment
team composed of talented, forward-thinking individuals. We've made very
encouraging progress and remain dedicated to making every effort to meet the
expectations of our investors.

        Sincerely

        /s/ JACK R. THOMPSON

        President

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

Performance

The Berger Information Technology Fund (the "Fund") gained 127.82% (Investor
Shares) and 128.23% (Institutional Shares) for the six-month period ended March
31, 2000. Its benchmark, the Wilshire 5000 Index,(1) gained 22.78% over the same
period.

The technology sector outshone all others for the first five months of this
reporting period. Then, in March, high volatility roiled the sector, shaking the
confidence of many technology investors and driving down prices.

Period in Review

The few semiconductor stocks we own were the best performers this quarter,
particularly Applied Micro Circuits, one of our top ten positions. Applied Micro
Circuits is a supplier of the type of silicon chips used in high-bandwidth
communications and networking applications. By the end of March 2000, investors
seemed to be looking for some shelter. This meant moving away from
multiples-of-revenue stocks back to multiples-of-earnings stocks. Profits always
count, and the expectation of becoming profitable is a very important
consideration when investing in emerging technology issues. Surprisingly, many
of the early e-commerce infrastructure stocks may move into the black in 2000.
One example is likely to be Vignette, a leading relation management software
vendor focused on e-commerce.

Another phenomenon that is rapidly being adopted is the business-to-business
exchange. First came the announcements from the big auto players for an auto
parts exchange. Then came the defense and aerospace industry. Clearly, the
writing is on the wall that the days are numbered for many of the middlemen and
distributors who try to muddy the waters between manufacturers and their
customers.

The industry that was hardest hit was the Internet segment and related issues,
such as companies that are tied to the Internet and e-commerce infrastructure.
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, BEA Systems, Allaire and Siebel Systems. The
Fund benefited greatly in 1999 from their presence but was hit hard in March
2000. We remain committed to this emphasis as we fully expect the buildout of
the Internet to continue. However, valuations will definitely adjust to any
major near-term disappointments as the current valuations leave little room for
downside mistakes.

Wireless communications and infrastructure companies were some of the hottest
areas in technology at the end of 1999, and the Fund benefited from holdings in
QUALCOMM and LM Ericsson, which we sold to lock in gains, and Nortel and Nokia.

Optical networking equipment companies, which support build-out of the
fiber-optic communications backbone, also generated substantial returns in the
fourth quarter 1999 as did some storage companies including two of our storage
holdings--EMC and Veritas.

Initial public offerings (IPOs) also made a positive contribution to the Fund's
performance during the period, although it is unclear whether this market for
IPOs will continue.

Looking Ahead

Our portfolio remains overweighted in software and services because we expect
the Internet build-out to continue regardless of the direction of the economy.
Given the heady levels of many current valuations in this segment, however, we
also expect to see adjustments in those valuations in response to any major
near-term economic disappointments. To help ensure a better night's sleep, we
believe technology investors should be well-diversified among asset classes and
that they should carefully consider the percentage of stock assets invested in
technology.

Going forward, we expect market volatility to continue over the near term,
fueled by large gyrations in share price caused by short-term investors and
traders who abandon the technology sector. Most of the companies we own are
profitable and are likely to remain that way. We believe in the e-commerce
expansion and will continue to play it through the software infrastructure
companies that are building the new virtual businesses in the new economy.

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. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue. Recent market volatility has significantly impacted performance.
Please contact us for updated performance information. 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.

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

Performance

Despite high market volatility and a correction in technology stocks that began
in March, the Berger New Generation Fund (the "Fund") had an outstanding 84.01%
(Investor Shares) and 82.12% (Institutional Shares) return for the six-month
period ended March 31, 2000. This return significantly outpaced the 17.50% gain
of the S&P 500 Index(1) over the same period.

The key reason for this dramatic outperformance was our investment in
innovative, fast-growing companies. We continue to hold a diverse mix of leading
technology companies that cross many industries, including broadband, energy,
healthcare, biotechnology, telecommunications, software, hardware and consumer
industries.

Period in Review

Technology was our strongest performing group of stocks this period. Some of our
strongest performance came from core technology infrastructure companies that
are building out the Internet, such as Applied Micro Circuits, Akamai and
Sycamore Networks. We also favor companies that are focused on
business-to-business enterprise, including i2 Technologies and Ariba. We believe
that these companies have strong long-term potential and a definite place in the
economy.

The strong supply/demand fundamentals, such as the increase in demand for oil,
coupled with a decrease in oil reserves, led to stellar performance from our
energy companies. We continue to favor the exploration and production and the
oil services industries, particularly National-Oilwell, BJ Services and Enron.

Among our consumer holdings, we have focused on the broadcasting and media
industries. The performance over the last six months has been mixed. Companies
such as Echostar Communications and Hispanic Broadcasting performed well. But on
the downside, Clear Channel Communications was a performance laggard. Clear
Channel became the victim of profit-taking and short-selling pressure after its
acquisition of SFX. We are optimistic about this acquisition, however, and
expect it to add to Clear Channel's growth rate over the next 24-36 months.

We are also finding opportunities in the financial sector, which contains new,
often overlooked growth companies. Knight/Trimark is a company that provides the
back-end processing of trades for some on-line brokers. As on-line transactions
increase, so will the demand for this type of company to provide more services.
Another example is Concord EFS, a company that provides credit and debit card
transaction processing for supermarkets and convenience stores.

Looking Ahead

Although we are pleased with the Fund's outperformance this reporting period, we
look to the future with guarded optimism. The market is seeking validation for
the high prices of many stocks. As a result, we estimate that the correction in
technology stocks, which began in March, may continue until valuations reach
less lofty levels--below those seen at the beginning of the year. While
uncomfortable, this sort of correction can be healthy for the market over the
long term and may present an excellent buying opportunity in the types of
innovative, fast-growing companies we seek for our Fund. We remain committed to
a wide array of companies in all sectors of the economy that have solid
long-term growth prospects. We will continue to focus on companies that have
open-ended opportunities, which we believe will facilitate their earnings and
cash growth and give heightened visibility to their business model.

* 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. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue. Recent market volatility has significantly impacted performance.

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

Performance

In the fourth quarter 1999, technology stocks surged impressively. They
continued their momentum through most of the first quarter 2000. On March 10,
however, profit-taking and interest rate fears began to drive prices down,
initiating a correction in these stocks. Investors then fled to lower-valuation
sectors such as financials, consumer cyclicals and energy.

Rotation into large cap stocks began late in the first quarter, simultaneous
with the weakness in technology stocks. This led to a one-month gain of more
than 10% in the Standard & Poor's (S&P) 500 Index(1) in March. Against this
backdrop, the Berger Select Fund (the "Fund") gained a strong 68.62% for the six
months ended March 31, 2000, significantly outpacing the 17.50% return of the
S&P 500 Index.

Period in Review

Individual stock selection was the key to the Fund's outperformance this
reporting period. Some of the Fund's top ten holdings had notable returns,
especially Cisco Systems, Sycamore Networks, and Sony Corporation.

Within technology, we continue to favor the companies with strong growth
prospects relating to the broadband build-out and the Internet. Broadband
companies provide the plumbing that enables broad acceptance of Internet
applications and services. Among our holdings that contributed to performance
are RF Micro Devices, a developer of wireless communication chips, and Redback
Networks, a provider of advanced networking systems that enable carriers, cable
operators and service providers to rapidly deploy high-speed access to the
Internet and corporate networks.

Charles Schwab rallied from its fourth quarter decline as investors focused on
the company's rapid asset inflows and the increase in earnings and revenue
estimates.

Energy companies, such as Ensco International, turned in stellar performances,
particularly in the first quarter 2000. Supply-and-demand fundamentals are quite
favorable in this sector, and we believe that strong earnings potential
continues to exist.

On the down side, poor performers included Spanish Broadcasting and Clear
Channel Communications. We expect both of these stocks to perform well as their
fundamentals play out over the next two to five years. Clear Channel was the
victim of profit-taking and short-selling pressure after its recent acquisition
of SFX. We are optimistic about this acquisition, however, and expect it to add
to Clear Channel's growth rate over the next 24-36 months.

Looking Ahead

We look for more volatility in the second quarter as the market digests more
potential rate increases by the Federal Reserve Board and tries to cope with
high valuations of premier growth companies. Once the market comes to terms with
these two major issues, we believe market leadership will be regained by those
companies delivering strong long-term growth.



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. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue. Recent market volatility has significantly impacted performance.

Performance

The Berger Small Company Growth Fund (the "Fund") had a very strong fiscal first
half ending March 31, 2000, gaining 90.96% (Investor Shares) and 89.48%
(Institutional Shares) while the Russell 2000 Index(1) and Russell 2000
Growth(2) Index rose 26.83% and 45.77%, respectively.

The Russell 2000 Index remained very strong during the fourth quarter of 1999,
through March 10 in the first quarter of 2000. This corresponded with the strong
move in technology stocks and small caps over the same period when profit-taking
and continued interest rate fears set in. The ensuing weeks to quarter end
marked the beginning of a correction in small cap and technology stocks. From
their highs, this move stole more than 11% in performance from the Russell 2000
Index and 16% from the Russell 2000 Growth Index in the first quarter alone.
Investors fled to large cap stocks, which are perceived to be less risky in
volatile markets, as well as to lower-valuation sectors such as financials,
consumer cyclicals and energy. This rotation to large cap stocks led to the S&P
500 Index(3) rise of more than 10% in the last month of the first quarter,
simultaneous to the weakness in small caps and technology stocks.

Period in Review

The dramatic fourth-quarter 1999 rise in technology stocks ended March 10, when
profit taking, interest rate fears and liquidity issues triggered the
correction. Prior to that many tech stocks had jumped more than 100% from the
market's October low.

Within technology, we continue to focus on companies assisting businesses in
transitioning to conducting their business over the Internet. Within software,
both Primus and Onyx Software enable companies to embrace the Internet and
contributed to performance during the two quarters. Also within this theme lies
the technology service companies that provide strategic Internet consulting
services. Forrester is a strong holding in this segment. We continue to favor
the semiconductor stocks, including Cree Research. Visibility remains strong
within the semiconductor capital equipment companies as well. These companies
provide the actual tools for building semiconductors.

Within healthcare, the biotechnology sector went on a roller coaster ride. After
tremendous strength in the fourth quarter of 1999 and the first two months of
2000, the group broke down in March 2000. Profit-taking, excessive equity
issuance and confusion around the potential for genomics, the study of mapping
and sequencing genes, led to the downfall. The long-term fundamentals for this
group are stronger than ever. We believe the biotech industry continues to
acquire critical mass as genomics and combinatorial chemistry, the process that
helps increase the efficiency of the drug development timeline, lead to an
explosion in new drug targets.

Within the consumer sector, radio stocks have been very volatile as well. Radio
stocks gave back most of their strong fourth-quarter gains during the first
quarter as high valuations led to profit-taking. We continue to favor the
long-term growth prospects for Emmis Communications within this industry.

Our energy exposure had stellar performance in the first quarter of 2000 after
being relatively flat in the fourth quarter of 1999. Supply-and-demand
fundamentals are quite favorable, and strong earnings potential exists. The
strength in the drilling industry reflects the move to a recovery in day rates
and utilization over the next twelve months. We believe that we are in the early
stages of a long-term recovery and the onshore drilling stocks are leading the
way. Contract driller Pride International has been a strong performer for the
fund.

Looking Ahead

We are cautious in our outlook for small caps and the market in the short term.
If economic metrics continue to show an overheating economy, interest rates will
continue to creep up, and the market may continue to be volatile and move
sideways as we enter the slower summer period. We estimate that this correction
in technology stocks may continue until their valuations are below the levels we
saw at the beginning of this year. While uncomfortable, this sort of correction
should be healthy for the market over the long term and may present an excellent
buying opportunity in the strongest growth stocks.

- --------------------------------------------------------------------------------
Performance

For the six-month period ended March 31, 2000, the Berger Small Cap Value Fund
(the "Fund") gained 9.37% (Investor Shares) and 9.50% (Institutional Shares).
While this significantly lagged the 26.83% return of the Russell 2000 Index,(1)
it outperformed the 5.41% return of the Russell 2000 Value Index.(2)

Growth was again the favored investment style this reporting period, as
evidenced by the 45.77% gain in the Russell 2000 Growth Index.(3) Yet, over the
Fund's 13-year history, growth and value styles have delivered very similar
average annual returns--11.1% for growth and 10.6% for value. These styles
seldom perform in lockstep; instead, there are cycles of underperformance and
outperformance. In the past 13 years, for example, value outperformed growth in
seven of those years and growth outperformed value in six years. The percentage
of outperformance was nearly identical in both cases: value led growth by an
average margin of 10.6% and growth led value by an average margin of 10.2%.

Period in Review

Our holdings in the energy sector were positive contributors to Fund
performance. We initiated investments in energy when oil prices were in the low
teens. Using the supply-and-demand theory, we correctly surmised that low prices
were causing reduced production and that a cyclical recovery was inevitable. Our
timely investments in the sector led to gains in some holdings that ranged from
20% to 120% this reporting period. We are taking profits and scaling back our
exposure to this sector.

Financials--our single largest sector--dragged down Fund performance, even
though the companies in our portfolio continued to experience strong loan growth
and fee income, and continue to buy back stock. The financials sector has
significantly underperformed the market because of continued concerns over
rising interest rates, even after five rate hikes by the Federal Reserve Board
since mid-1999. We remain committed to this sector, however, because its
near-term problems have depressed earnings multiples to attractive levels
relative to the general market.

We recently committed a significant portion of Fund assets to the homebuilding
and insurance industries. Both groups are selling at or beneath their all-time
low valuations because of the market's overdiscounting of short-term problems.
We believe the correction of these problems to be an economic inevitability.

In the insurance industry, weakness in policy prices is being corrected, and
premium rates are being aggressively increased. Therefore, we have expanded
investment in two portfolio companies, Old Republic and IPC Holdings. These
companies have excess capital, strong industry positions, proven management and
stock prices that are 75% below their two-year highs.

In the homebuilding group, we have made investments in Lennar and Pulte. Because
of the market's knee-jerk reaction to higher interest rates, these stocks have
declined about 55% from their previous highs. At these prices, our investments
are trading at five to six times estimated 2000 earnings--levels that haven't
been this low since housing starts declined 30% in 1990.

Looking Ahead

In the past two-and-one-half years, there has been a huge disparity in
performance of growth stocks and value stocks. This is an indication, in our
opinion, of the unprecedented excesses, both positive and negative, that exist
in the market today--and that we have referred to in previous communications.
Investor preoccupation with large companies having a high rate of short-term
momentum has created relative valuations in the small company value area not
seen in more than 30 years. We continue to believe that capital will, in the
long term, flow to investments providing the best returns with the lowest risk.
In the meantime, we will continue to seek investments with the type of
risk-reward profile that enables us to maintain a portfolio that delivers
above-average long-term returns at below-average risk

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.

Performance

The Berger Mid Cap Growth Fund (the "Fund") had a very strong fiscal first half
ending March 31, 2000, gaining 94.36% while the S&P Mid Cap 400 Index(1) rose
32.06%.

The S&P Mid Cap 400 Index remained very strong in the fourth quarter of 1999 and
the first quarter of 2000. The Index outperformed both the small caps in the
Russell 2000 Index(2) and the large caps in the S&P 500 Index(3) during the
first quarter of 2000. This first quarter outperformance was due to multiple
issues. The S&P Mid Cap 400 Index's heavy weighting in energy and specifically
utilities, which were up more than 14% in March, contributed to the divergent
performance versus the small caps in the Russell 2000 Index. Also, investors
fled to larger cap stocks, which are perceived to be less risky in volatile
markets, as well as to lower-valuation sectors such as financials, consumer
cyclicals and energy. Profit-taking and continued interest rates fears were the
primary drivers of the market rotation. This rotation to larger cap stocks led
to the 8% rise in the S&P Mid Cap 400 Index and the S&P 500 Index rise of more
than 12% in the last month of the first quarter, simultaneous with the weakness
in small caps and technology stocks.

Technology stocks climbed dramatically in the fourth quarter 1999 and through
March 10, 2000, as investors continue to recognize the strong growth prospects
relating to the broadband build-out and the Internet. Broadband companies
provide the plumbing that enables broad acceptance of Internet applications and
services. This marked a major upward move in technology stocks, many of which
rose more than 100% in a five-month period. Profit-taking, interest rate fears
and liquidity issues led to the beginning of a correction in technology stocks,
which began March 10.

Period in Review

Within technology, optics continues to be a focus, and JDS Uniphase, a top
provider of advanced fiber-optic components and modules, contributed to
performance. The semiconductor and semi-capital equipment companies were also
strong contributors. Both PMC-Sierra and Applied Micro Circuits within
telecommunication semiconductors remained solid holdings. Although Internet
performance was quite strong in the fourth quarter of 1999, it was less than
stellar in the first quarter of 2000. Both Verisign and CMGI were hit with
profit-taking. Longer term, the fundamentals for Internet growth remain strong.

Within healthcare, the biotechnology sector went on a roller coaster ride. After
tremendous strength in the fourth quarter of 1999 and the first two months of
2000, the group broke down in March 2000. Profit-taking, excessive equity
issuance and confusion around the potential for genomics, the study of mapping
and sequencing genes, led to the downfall. The long-term fundamentals for this
group are stronger than ever. We believe the biotech industry continues to
acquire critical mass as genomics and combinatorial chemistry, the process that
helps increase the efficiency of the drug development timeline, lead to an
explosion in new drug targets.

Within the consumer sector, radio stocks have been very volatile as well. Radio
stocks gave back most of their strong fourth-quarter gains during the first
quarter as high valuations led to profit-taking. We continue to favor the
long-term growth prospects for Cox Radio within this industry.

Our energy exposure had strong performance in the first quarter of 2000 after
being relatively flat in the fourth quarter of 1999. Supply-and-demand
fundamentals are quite favorable, and strong earnings potential exists.

Initial public offerings (IPOs) also made a positive contribution to the Fund's
performance during the period, although it is unclear whether this market for
IPOs will continue.

Looking Ahead

We are cautious in our outlook for mid caps and the market in the short term. If
economic metrics continue to show an overheating economy, interest rates will
continue to creep up, and the market may continue to be volatile and move
sideways as we enter the slower summer period. We estimate that this correction
in technology stocks may continue until their valuations are below the levels we
saw at the beginning of this year. While uncomfortable, this sort of correction
should be healthy for the market over the long term and may present an excellent
buying opportunity in the strongest growth stocks.

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. IPO's have made a significant contribution to
the Fund's recent performance. There can be no assurance that such contribution
will continue. Recent market volatility has significantly impacted performance.

Performance

We are pleased to report that in the six months ended March 31, 2000, the Berger
Mid Cap Value Fund (the "Fund") gained 24.21% compared with the 14.01% for the
S&P Mid Cap Value Index,(1) 32.06% for the S&P Mid Cap 400 Index,(2) and 17.50%
for the S&P 500 Index.(3) Our Fund underperformed the S&P Mid Cap 400 Index
because growth stocks continued to outpace value stocks. We outperformed the
other indices mainly because we had strong appreciation in the prices of some of
our severely depressed technology and energy stocks.

Calendar year 1999 was the sixth consecutive year in which the S&P Mid Cap 400
Index underperformed the large cap-dominated S&P 500 Index (14.72% vs. 21.03%).
In the preceding five years (1988-1993), mid caps significantly outperformed
large caps. There is a cycle. We believe that mid caps (and especially value mid
caps) now are relatively under priced and poised for an extended period of
outperformance. Assuming world economic prospects continue to be positive, mid
cap value stocks should have good earnings growth and benefit from a broadening
of the market as investors reduce their recent years' narrow focus on
high-growth companies.

Period in Review

The financial sector remains our largest sector, constituting 26.8% of the
portfolio. Although we have had gains in this sector, it generally has
underperformed as interest rates have continued to rise. However, the
fundamentals of our holdings have been solid--their earnings and dividends have
been increasing, and many are buying back their stock. Regional bank stocks now
are cheaper than at any time since the lows of 1990. (These stocks subsequently
had tremendous appreciation for most of the rest of the decade of the `90s as
interest rates declined.) Moreover, we expect consolidation to continue. For
example, the acquisition of CCB, one of our high-quality bank holdings, was
recently announced. We increased our positions in real estate investment trusts
(REITs) as they have current dividend yields of almost 9% and are selling near
net asset value.

We continued to use the extreme strength in technology stocks to reduce or
eliminate many of our holdings in this sector. We bought these issues when Wall
Street was focused on uncertain short-term factors, not on favorable long-term
trends. Subsequently, these stocks' strong long-term fundamentals have been
"rediscovered" by the market, and they have become adequately valued. As this
has happened, the risk/reward relationships of the stocks became less favorable.

For example, we reduced our exposure to Aspect, Convergys, Comdisco, Tektronix
and Telephone Data, and eliminated Adaptec, Analog Devices and Tellabs. When we
purchased each of these stocks, its price was down 50%-75% from its recent high,
and they were selling at reasonable multiples of book value and earnings power.
The companies had good balance sheets, positive cash flow and, in most cases,
stock buyback programs. If these stocks experience temporary problems again in
the future, we may want to reinvest. In the meantime, some of the proceeds of
these sales were deployed to other financially sound issues that more recently
fell into what we believe is only temporary market disfavor. These include
Autodesk, Complete Business Solutions, Robert Half, Silicon Graphics and
Structural Dynamics. When we purchased these stocks, they were all down over 50%
from their recent highs, and most were at below-average price/earnings
valuations. By investing in temporarily out-of-favor industries and companies,
we seek to lessen risk while maintaining strong upside potential.

Looking Ahead

Most major stock market indices are near record high levels, particularly the
valuations of "new economy" stocks. With the U.S. economy growing at an
unsustainable pace, the Federal Reserve continuing to raise interest rates and
some signs of accelerating inflation, the market could be vulnerable. However,
assuming the economy has a soft landing, any market correction should be
relatively short-lived.

We are more comfortable with mid and small cap value stocks than we are with the
overall market. We are still finding many stocks to buy at 10-15 times earnings,
at less than 2.5 times book value and with strong balance sheets and cash flows.
Interestingly, corporate America is also attracted to undervalued mid and small
cap companies and is acquiring them at a record pace. About 10% of our portfolio
has been acquired at premiums of 25-50% above market prices. As the performance
of high-momentum stocks wanes, we expect investor interest to return to the
value sector.

Past performance is no guarantee of future results.

The market performed very differently in the two quarters included in this
reporting period. In the fourth quarter 1999, technology stocks fueled a massive
surge in the market. The new year started slowly, but rallied towards the end of
January and into February with technology stocks again leading the way. In
March, things changed. Financial stocks started to rally. Energy stocks,
particularly in the oil and gas drilling and equipment industries, were strong
throughout the quarter as the market started to anticipate the positive earnings
outlook for energy companies.

Period in Review

Effective January 31, 2000, we changed the name of the Fund from the Berger 100
Fund to the Berger Growth Fund. We felt the name change is a more accurate
reflection of the Fund's objective and style.

Individual stock selection was the key to the Fund's outperformance this
reporting period. In the fourth quarter 1999, many of the Fund's largest
holdings had notable returns, especially those in the technology sector, which
even outperformed that sector's average for the quarter. Strong upward moves
were registered that quarter by Qualcomm, Genentech, Sony, Veritas Software and
ST Microelectronics.

During the first quarter 2000, the Fund continued to benefit from increases in
some of its largest holdings, including Network Appliance, Echostar and Cisco
Systems. Oracle Japan registered a big gain in the first quarter, which reflects
accelerating growth in the software market (Oracle produces database software)
after the "Y2K" lockdowns of 1999. Charles Schwab rallied from its
fourth-quarter decline as investors focused on the company's rapid asset inflows
and the increase in earnings and revenue estimates.

We own some outstanding companies in the energy sector. The strong supply/demand
fundamentals in energy led to stellar performance from companies such as Enron
Corporation, Ensco International and Transocean Sedco Forex, the world's largest
offshore drilling contractor. Enron specializes in the exploration and
production of natural gas, while Ensco and Transocean Sedco Forex are drilling
and oil service companies.

On the down side, poor performers included Agile Software and Clear Channel
Communications. However, we expect both of these stocks to perform well as their
fundamentals play out over the next two to five years. Agile, which exploded out
of the box, became one of the most expensive stocks in the software industry.
The market readjusted the company's valuation throughout the quarter, making
Agile in a sense the victim of its own success. Once this period of readjustment
is over, we expect investors to refocus on Agile's fundamentals. Clear Channel
was the victim of profit-taking and short-selling pressure after its recent
acquisition of SFX. We are optimistic about this acquisition, however, and
expect it to add to Clear Channel's growth rate over the next 24-36 months.

Looking Ahead

We believe the Fund is well-positioned for the growth opportunities that we see
for the rest of the year and into 2001. Our continued focus on careful stock
selection to identify the best large cap growth companies should provide a solid
base to build on for the rest of the year.

We look for continued volatility in the following months as the market digests
more potential rate increases by the Federal Reserve Board and tries to cope
with high valuations of premier growth companies. Once the market comes to terms
with these two major issues, we believe market leadership will be regained by
those companies delivering strong long-term growth.

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

Performance

The Berger/BIAM International Fund (the "Fund") gained 21.34% in the six-month
period ended March 31, 2000, compared with 17.00% 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 quarter
2000, however. Half of the markets in the 22 countries that comprise the MSCI
World Index registered gains and half registered losses (as measured in U.S.
dollars). Investor enthusiasm for particularly high-flying Internet stocks
dimmed during the quarter as the pricey valuations of these stocks began to be
called into question. Indeed, in Europe, there was profit-taking from the
technology, media and telecommunications sectors and some evidence that this
money was directed toward financial and cyclical stocks. Rising interest rates
in all markets except Japan also served as a drag on returns.

Period in Review

The Fund's investment in telecommunications, media and technology stocks was the
key reason that it was able to outperform the MSCI EAFE Index this reporting
period. The most significant positive contribution came from stocks in the
Growth in Telecommunications theme. Vodafone/Mannesmann agreed to a friendly
merger in the first quarter 2000, ending their lengthy takeover saga and
creating the largest mobile phone operator in the world, with businesses in 25
countries. The combined entity is now our largest holding and, given its global
reach and superior growth rate, one we continue to believe in strongly. Other
notable performers in the sector were KPN and Ericsson.

Japanese-quoted stocks, such as Murata Manufacturing, in the Technological
Innovation theme delivered strong performance in the fourth quarter 1999. Stocks
in the Undervalued Asset Profile theme aided performance in the first quarter.
Vivendi is one of the companies at the forefront of Europe's corporate activity,
which favorably impacted its share price. Philips Electronics, which we added to
the portfolio in the first quarter, moved up strongly following its announcement
that earnings had more than tripled over the previous year's figures. Total Fina
had a 24% increase in profits, aided by the recent run-up in crude oil prices.

Other companies that performed well were News Corp., one of the world's premier
media companies, and Takeda Chemical. Analysts are forecasting that Takeda's
diabetes drug, Actos, will gain market share now that the U.S. Federal Drug
Administration has halted the sale of its largest competitor, Rezulin.

Financial stocks continued their underperformance; their negative returns were
largely a reaction to anticipated, and then to actual, increases in global
interest rates. Stocks in the Positive Banking Environment and Growth in
Personal Savings Products themes felt this rate move, including ING, which fared
poorly despite announcing a 54% increase in net operating profits in the first
quarter. We do not believe that the financial stocks in our portfolio deserve
the valuations currently attributed to them by the market.

Looking Forward

Toward the end of March, there was some respite for value-oriented investors as
several major global, blue-chip, old-economy companies behaved like hot Internet
stocks, appreciating 20%-25% in a matter of days. On a global basis, rising
interest rates have started to challenge the high valuations of certain stocks
and to make other, previously ignored investment options more attractive. When
all is said and done, most of the old-economy companies have valuable products
and competent, proven management. Undoubtedly, some of these companies will
struggle, but there will also be winners as equity market strength broadens. We
believe our job is to identify these winners. We will continue to take profits
from stocks that we believe are close to or at full valuation and redirect the
money to areas where we find value.

Past performance is no guarantee of future results.

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. Investment return and principal value will fluctuate so that
shares, when redeemed, may be worth more or less than their original cost.

Performance

Despite high volatility, the market continued to favor growth stocks over value
stocks this reporting period. Against this backdrop, the Berger Growth and
Income Fund (the "Fund"), which invests primarily in large cap companies with
strong fundamentals and growth prospects, significantly outperformed its
benchmark, the S&P 500 Index.(1) The Fund was up 62.07% for the six-month period
ended March 31, compared with 17.50% for the Index.

The market performed very differently during the two quarters included in this
reporting period. In the fourth quarter 1999, technology stocks fueled a massive
surge in the market. The new year started slowly but rallied toward the end of
January and into February with technology stocks leading the way. In March,
things changed. Financial stocks began to rally. Energy stocks, particularly in
the oil and gas drilling and equipment industries, were strong throughout the
quarter as the market started to anticipate the positive earnings outlook for
energy companies.

Period in Review

Individual stock selection was the key to the Fund's outperformance this
reporting period. In the fourth quarter 1999, many of the Fund's largest
holdings had notable returns, including Nokia, QUALCOMM, Amgen and Toyota.

During the first quarter 2000, the Fund continued to benefit from increases in
some of its largest holdings, including Network Appliance, Echostar and Cisco
Systems. Oracle Japan registered a big gain for the quarter, which reflects
accelerating growth in the software market (Oracle produces database software)
after the "Y2K" lockdowns of 1999. Charles Schwab rallied from its
fourth-quarter decline as investors focused on the company's rapid asset inflows
and the increase in earnings and revenue estimates.

We own some outstanding companies in the energy sector. The strong supply/demand
fundamentals in energy led to stellar performance from companies such as Enron
Corporation, a company that specializes in the exploration and production of
natural gas, and ENSCO International, an international offshore drilling
company.

On the down side, poor performers included Alltel and Clear Channel
Communications. We expect both of these stocks to perform well as their
fundamentals play out over the next two to five years. Alltel, a
telecommunications company with cellular operations, was hurt by investor
concerns over industry wide reductions in cellular phone roaming fees. Clear
Channel was the victim of profit-taking and short-selling pressure after its
recent acquisition of SFX. We are optimistic about this acquisition, however,
and expect it to add to Clear Channel's growth rate over the next 24-36 months.

Looking Ahead

We believe the Fund is well positioned for the growth opportunities that we see
for the rest of the year and into 2001. Our continued focus on careful stock
selection to identify the best large cap growth companies should provide a solid
base to build on for the rest of the year.

We look for continued volatility in the second quarter as the market digests
more potential rate increases by the Federal Reserve Board and tries to cope
with soaring valuations of premier growth companies. Once the market comes to
terms with these two major issues, we believe market leadership will be regained
by those companies delivering strong long-term growth.

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

Performance

The market performed very differently in the two quarters included in this
reporting period. In the fourth quarter 1999, technology stocks surged
impressively. The new year started with a precipitous sell off in growth stocks,
followed by a recovery and then, beginning March 10, another strong sell off.
Despite this high volatility, Berger Balanced Fund (the "Fund"), which invests
in a balance of stocks and fixed income securities, gained 37.33% over the
six-month period ended March 31, 2000. This was considerably higher than the
17.50% gain registered by its benchmark, the S&P 500 Index(1). This performance
is attributable to two factors: (1) the Fund's equity-oriented asset allocation,
and (2) our focus towards high quality, market leading, large cap growth
companies.

Period in Review

As of March 31, the Fund's net assets were allocated as follows: 68% stocks, 28%
fixed income and 4% cash.

The stock side of the portfolio benefited greatly from the fourth quarter's
strong technology sector. Many of our technology holdings had stand-out
performances that quarter, including Oracle Corp., QUALCOMM, Lam Research,
Yahoo! and Motorola. Performance was further enhanced in the first quarter 2000
by the dominant, large cap stocks we added to the portfolio at the beginning of
the quarter, such as Intel, Corning, Qwest Communications and Charles Schwab.

Charles Schwab rallied from its fourth quarter decline as investors focused on
the company's rapid asset inflows and the increase in earnings and revenue
estimates. The Fund also enjoyed good returns from some of its consumer
holdings, which bounced back after a weak fourth quarter, particularly Best Buy
and Nordstrom.

On the downside, poor performers this reporting period included Alltel and Clear
Channel Communications. We expect both of these stocks to perform well as their
fundamentals play out over the next two to five years. Alltel, a
telecommunications company with cellular operations, was hurt by investor
concerns over industry-wide reductions in cellular phone roaming fees. Clear
Channel was the victim of profit taking and short selling pressure after its
recent acquisition of SFX. We are optimistic about this acquisition, however,
and expect it to add to Clear Channel's growth rate over the next 24-36 months.

On the fixed income side of the portfolio, we continue to favor the high-quality
bonds that help protect the Fund in a volatile market. We continue our short
duration posture, although we have slightly extended the average maturity of our
holdings to almost four years to take advantage of pricing opportunities.

Looking Ahead

We look for continued volatility in the second quarter as the market digests
more potential rate increases by the Federal Reserve Board and tries to cope
with soaring valuations of premier growth companies. Once the market has come to
terms with these two major issues, we believe market leadership will be regained
by those companies that deliver strong long-term growth.

Past performance is no guarantee of future results.

generally recognized indicator used to measure overall performance of the U.S.

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. 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. IPO's
have made a significant contribution to the Fund's recent performance. There can
be no assurance that such contribution will continue. Recent market volatility
has significantly impacted performance. Please contact us for updated
performance information.

Berger Funds o March 31, 2000 Combined Semi-Annual Report

Notes to Financial
Statements
March 31, 2000 (Unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Organization

Berger Information Technology Fund ("TECH"), Berger New Generation Fund ("BNG"),
Berger Select Fund ("BSEL"), Berger Small Company Growth Fund ("BSCG"), Berger
Small Cap Value Fund ("BSCV"), Berger Mid Cap Growth Fund ("BMCG"), Berger Mid
Cap Value Fund ("BMCV"), Berger Growth Fund (formerly Berger 100 Fund)
("Growth"), Berger Growth and Income Fund ("BG&I"), Berger Balanced Fund
("BBAL"), and Berger/BIAM International Fund ("BBIF") (individually the "Fund"
and collectively, the "Funds") are open-end management investment companies
registered under the Investment Company Act of 1940, as amended (the "1940
Act"). Shares of each fund are fully paid and non-assessable when issued. All
shares issued by a particular Fund participate equally in dividends and other
distributions by that Fund. The investment objective of each Fund is capital
appreciation, including the BG&I and BBAL, which also pursue current income.

Growth and BG&I are corporations registered in the State of Maryland. TECH, BNG,
BSEL, BSCG, BMCG, BMCV and BBAL are separate series established under the Berger
Investment Portfolio Trust ("BIP Trust"), a Delaware business trust. BSCV is the
only series established under the Berger Omni Investment Trust ("OMNI Trust"), a
Massachusetts business trust. Prior to July 2, 1999, TECH was known as the
InformationTech 100 Fund ("InfoTech"). On July 2, 1999,all of the outstanding
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/BIAM Worldwide Funds
Trust ("BBWF Trust"), a Delaware business trust. Other series or portfolios may
be added under each trust in the future. All costs in organizing the trusts were
borne by Berger LLC ("Berger"), or BBOI Worldwide LLC ("BBOI").

BBIF invests all of its investable assets in the Berger/BIAM International
Portfolio (the "Portfolio"), a series of Berger/BIAM Worldwide Portfolios Trust
("BBWP Trust").

The value of such investment reflects BBIF's proportionate interest in the net
assets of the Portfolio (7% at March 31, 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.

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. 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.
Prices of foreign securities are converted to U.S. dollars using exchange rates
determined prior to the close of the Exchange. 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 are deter- mined 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 directors/trustees of the Funds.

                       Berger Funds o March 31, 2000 Combined Semi-Annual Report


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

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 with the exception
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. Interest income is recorded on the accrual basis and
includes accretion of discount and amortization of premium. 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 (including the investment advisory fee, custodian fees, independent
accountants' fees, recordkeeping and pricing agent fees) 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.

Common Expenses

Certain expenses that 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.

2. Agreements

Berger renders investment advisory services 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.

Pursuant to an Administrative Services Agreement, whereby BBOI serves as the
administrator to BBIF, BBIF pays BBOI a fee at an annual rate equal to the
lesser of 0.45% of its average daily net assets or BBOI's annual cost to provide
or procure such services plus 0.02% of BBIF's average daily net assets. Under
the Agreement, BBOI is responsible at its own expense, for providing or
procuring administrative services reasonably necessary for the operation of
BBIF, including recordkeeping and pricing services, custodian services, transfer
agency and dividend disbursing services, tax and audit services, insurance,
printing and mailing to share- holders of prospectuses and other required
communication and certain other administrative services. BBOI has delegated the
administration of BBIF to Berger.

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 & Trust ("State Street"), which also serves as the Funds'
custodian and transfer agent. 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, pricing and transfer agency
services are subject to reduction by credits earned by each Fund, based on the
cash balances of each Fund held by State Street as custodian, and by credits
received from directed brokerage transactions.

DST Systems, Inc. ("DST"), an affiliate of Berger through a degree of common
ownership, provides shareholder accounting services to the Funds as a
sub-transfer agent. 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 period ended March 31, 2000, the following credits were earned:

</TABLE>

Certain officers and/or directors of Berger and BBOI are also officers and/or
directors/trustees of the Funds. Directors/Trustees who are not affiliated with
Berger or BBOI are compensated for their services according to a fee schedule
which includes an annual fee component and a per meeting fee component. For the
period ended March 31, 2000, such directors'/trustees' fees and expenses totaled
$137,755 for the Funds.

The Funds 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
certain of the Funds until distribution in accordance with the Plan.

Futures Contracts

Each Fund may enter futures contracts for hedging purposes. Upon entering a
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. Such receipts
or payments are known as "variation margin" and are recorded by a Fund as
variation margin receivable or payable on futures contracts. During the period
the futures contracts are open, changes in the value of the contracts are
recognized on a daily basis to reflect the market value of the contracts at the
end of each day's trading and are recorded as realized or unrealized gain or
loss, as appropriate. A Fund's use of futures contracts may subject it to
certain risks as a result of unanticipated movements in the market. A lack of
correlation between the value of an instrument underlying a futures contract and
the asset being hedged, or unexpected adverse price movements, could render a
Fund's hedging strategy unsuccessful and result in losses. In addition, there
can be no assurance that a liquid secondary market will exist for any contract
purchased or sold. Realized gains or losses on these contracts are presented as
a separate component of Net Realized Gain (Loss) on Investments and Foreign
Currency Transactions in the Statement of Operations. At March 31,2000,the Funds
had no outstanding futures contracts.

Forward Contracts And Options

Each Fund may hold certain types of forward contracts and/or options 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, could render a Fund's hedging strategy unsuccessful and result in
losses. In addition, there can be no assurance that a liquid secondary market
will exist for the instrument. Realized gains or losses on these investments are
included in Net Realized Gain (Loss) on Investments and Foreign Currency
Transactions in the Statement of Operations. At March 31, 2000, the Funds held
no options or open forward 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 financial institutions. Loans of portfolio securities are collateralized
by cash in an amount equal to at least 102% of the market value of the loaned
securities at the time the loan is made. The collateral is evaluated daily to
ensure that it exceeds the current market value of the loaned securities.

The cash collateral received is invested in a money market fund and any income
generated by such investment, net of any rebates paid by State Street to
borrowers, is remitted to State Street, as lending agent, and the remainder is
paid to the Fund.

At March 31, 2000, the Funds had securities on loan with the following market

1. See the Portfolio's Notes to Financial Statements for market value of
securities on loan.

Income earned from securities lending transactions is included in securities
lending income in the Statement of Operations.

Repurchase Agreements

Repurchase agreements held by a Fund are fully collateralized by U.S. government
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 Investments 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.

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
financial statements and tax basis have been reclassified to paid-in-capital.

At September 30, 1999, BBIF had capital loss carryovers in the amount of
$593,333, expiring on September 30, 2007, which may be used to offset future
realized gains for federal income tax purposes.

Growth, BBAL, and BBIF incurred and elected to defer post-October 31 net capital
and/or currency losses of $12,732, $165,238, and $234,056, respectively, to the
year ended September 30, 2000.

4. Line of Credit

BNG, BSEL, BSCG, BSCV, BMCG, BMCV, Growth, BG&I, BBAL and the Portfolio are
party to an ongoing agreement with certain banks that allows the Funds,
collectively, to borrow up to $150 million for temporary or emergency purposes.
Interest on the borrowings, if any, is charged to the specific Fund or Portfolio
at the Federal Funds Rate plus 50 basis points. In addition, the line of credit
requires a quarterly payment of a commitment fee based on the average daily
unused portion of the line of credit. At March 31, 2000, BSCG had borrowings
outstanding of $12,000,000. No other Funds had line of credit borrowings
outstanding at March 31, 2000.

6. Other Matters

Effective March 31, 2000, the trustees of the OMNI Trust approved closing both
share classes of BSCV. During the period in which the Fund is closed to new
investors, Berger shall reduce the 12b-1 fee payable by BSCV; Inv by the amount
of such fee that is not utilized by Berger to provide or to compensate third
party administrators or other companies for providing shareholder services to
shareholders in connection with the distribution of shares.

7. Subsequent Events

On January 19, 2000, Berger and BIAM entered into an agreement to dissolve BBOI.
This agreement was approved by shareholders on May 5, 2000. The dissolution of
BBOI will have no effect on the investment advisory services to or on the fees
borne by BBIF for advisory services. 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.
Additionally, BBIF has been renamed Berger International Fund and the BBWF Trust
has been renamed Berger Worldwide Funds Trust.

1. Organization and Significant Accounting Policies

Organization

The Berger/BIAM 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/BIAM
Worldwide Portfolios Trust (the "Trust"), which was organized as a Delaware
business trust on May 31, 1996. All costs in organizing the Trust were borne by
BBOI Worldwide LLC ("BBOI"), the investment advisor of the Portfolio. Currently
there are three investors in the Portfolio, the Berger/BIAM International Fund,
the International Equity Fund and the Berger/BIAM International CORE Fund.

The investment objective of the Portfolio is long-term capital appreciation. The
Portfolio invests primarily in common stocks of well-established companies
located outside of the United States.

The Portfolio is advised by BBOI, which has delegated daily investment
management of the Portfolio to Bank of Ireland Asset Management (U.S.) Limited
("BIAM"). Berger LLC ("Berger") and BIAM each own 50% of BBOI.

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. 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.
Prices of foreign securities are converted to U.S. dollars using exchange rates
determined prior to the close of the Exchange. 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 and amortization of premium. 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 renders investment advisory services to the Portfolio pursuant to an
agreement that provides for an investment advisory fee to be paid to BBOI at the
annual rate of .90% of the Portfolio's average daily net assets. BBOI is also
responsible for providing for or arranging for all managerial and administrative
services necessary for the operations of the Portfolio BBOI pays BIAM a
sub-advisory fee from the investment advisory fee it receives from the
Portfolio.

The Portfolio has also entered into recordkeeping and pricing agreements with
State Street Bank & Trust ("State Street"), which also serves as the Portfolio's
custodian and transfer agent. 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, pricing
and transfer agency services 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
and/or BBOI. Trustees who are not affiliated with Berger and/or BBOI 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 period ended March 31, 2000,totaled $8,213.

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 Berger Funds until
distribution in accordance with the Plan.

3. Investment Transactions

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 gains or losses on these
securities are included in Net Realized Gain (Loss) on Investments 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 financial institutions. Loans of
portfolio securities are collateralized by cash in an amount equal to at least
102% of the market value of the loaned securities at the time the loan is made.
The collateral is evaluated daily to ensure that it exceeds the current market
value of the loaned securities. The cash collateral received is invested in a
money market fund and any income generated by such investment, net of any
rebates paid by State Street to borrowers, is remitted to State Street, as
lending agent, and the remainder is paid to the Portfolio.

At March 31, 2000, the Portfolio had securities on loan with a market value of
$24,699,259. Income earned from securities lending transactions is included in
securities lending income in the Statement of Operations.

Repurchase Agreements

Repurchase agreements held by the Portfolio are fully collateralized by
U.S. government 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 Investments 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 Berger Funds, 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 March 31, 2000,
the Portfolio had no borrowings outstanding on the line of credit.

5. Subsequent Events

On January 19, 2000, Berger and BIAM entered into an agreement to dissolve BBOI.
This agreement was approved by shareholders on May 5, 2000. The dissolution of
BBOI will have no effect on the investment advisory services to the Portfolio;
however, effective May 12 the investment advisory fee charged to the Portfolio
will be reduced according to the following schedule:

Over $1 billion                                         .75%
</TABLE>

Immediately upon shareholder approval Berger became the Fund's advisor and BIAM
continues to be responsible for the day-to-day management of the Portfolio as
sub-advisor. Additionally, the Portfolio has been renamed the Berger
International Portfolio and the Trust has been renamed Berger Worldwide
Portfolios Trust.
