INFORMATION ON YEAR-END DISTRIBUTIONS

To help you with tax planning, we provide you with the preliminary capital gains
amounts our funds may distribute near year-end. Estimates are now available on
our Web site at bergerfunds.com or by calling Investor Services at (800)
551-5849.

Please keep in mind that these amounts are not final and may be revised before
the December 27 record date. As we approach the record date, you may want to
check back with us for updated numbers.

And, please remember that a capital gains distribution does not change the total
value of your account so long as the distribution is reinvested in additional
fund shares. By reinvesting distributions rather than taking them in cash, you
put the power of compounding to work for you. Over time, this may increase the
value of your investment considerably.

Below are several important dates you'll want to remember:

DECEMBER 27 -- Record date. All shareholders of record as of close of business
will receive the distribution.

DECEMBER 28 -- Ex-dividend and reinvestment date. On this date the fund's share
price will drop by an amount equal to the capital gains distribution (plus or
minus any share price fluctuation that may normally occur that day.) Investors
who chose to have their distributions reinvested will receive additional shares
of the fund.

DECEMBER 30 -- Payable date. Checks are issued to investors who elected to
receive their distributions in cash.

A Message
for Berger Investors


IT'S BEEN SEVERAL MONTHS SINCE THE MANAGEMENT CHANGES AT BERGER, AND I'D LIKE to
give you a report on our progress. Following is a report on our growth
funds--those most directly affected by the changes. I've also included some good
news about fees and a few thoughts on market volatility.

Each Berger Fund shares the same goal--to provide consistently competitive
performance over the long term--performance that will place it in the top
quarter of its peer groups despite short-term market fluctuations that may favor
one investment style over another.

That's a tall order. Our talented, committed investment team has taken
important initial steps toward establishing the kind of long-term competitive
records that investors deserve.(1) I'm pleased with our progress after these
early months.

BUILDING A STRONG FOUNDATION

At the top of our priority list has been the Berger 100 Fund. Several years
of sub-par performance had left investors feeling frustrated. I'm not going
to offer a glowing description of how the fund has done a complete
turnaround. I am going to tell you the fund is doing better, and we will
strive to continue this trend. Co-managers John Jares and Tino Sellitto, who
took over in May, have made steady progress. The fund has gained significant
ground among its peers and has pulled ahead of the S&P 500 Index.(2) It's a
promising start on strengthening the fund's track record and restoring
confidence.

An unsung hero is the Berger Growth and Income Fund. It's never been a
headline grabber, but the performance of this fund has earned it an Overall
Morningstar Rating-TM- of 4 stars among 3,210 domestic equity funds as of
September 30, 1999.(3) Manager Tino Sellitto, who took over last November,
has guided Growth and Income to the upper echelon of its peer group this
year, well ahead of the S&P 500.(2)

COMING OF AGE

Berger Balanced Fund is a youngster compared with the Berger Growth and Income
Fund, but now beginning its third year, manager John Jares has established the
foundation for the kind of long-term record we are committed to building for
every Berger Fund. An excellent performer last year, the Balanced Fund remains
at the top according to Lipper, ranking number 1 of 421 balanced funds for the
one-year period ended September 30, 1999.(4)

Berger New Generation Fund is also coming of age. It has earned the highest
Overall Morningstar Rating-TM- of 5 stars among 3,210 domestic equity funds
as of September 30, 1999.(3) Manager Mark Sunderhuse, who took over in
February, has kept the fund on a winning track, outdistancing the S&P 500(2)
as well as most competitors.

Amy Selner continues to build an impressive record with the Berger Mid Cap
Growth Fund, and since taking over Berger Small Company Growth Fund last
November, she has enhanced an already solid record.

Nearing the end of its second year, Berger Mid Cap Growth Fund continues to be
one of the most solid performers in its peer group and is well ahead of the S&P
Mid Cap 400 Index.(5) Small-company stocks appear to have begun emerging from a
prolonged bear market, and Berger Small Company Growth Fund remains very
competitive in its peer group and out in front of the Russell 2000 Index.(6)

The "Best of Berger" is represented in the Berger Select Fund. Each of our four
growth managers contributes a limited number of what he or she considers to be
their best current investment opportunities to our only non-diversified or
focused fund. John, Tino, Mark and Amy took over in May and have adopted a
strategy that has resulted in significantly lower turnover, yet performance has
remained strong. The fund is far outpacing the S&P 500(2) and continues to make
a good showing among its peers.

MANAGEMENT FEES REDUCED

Another positive change for Berger investors is a reduction in the management
and administrative fees on all domestic Berger Funds, effective October 1, 1999.
For our small-company-oriented funds the old flat fee of .90% per year has been
changed to begin at .85% with new breakpoints when the funds reach $500 million
and $1 billion in assets. Funds that have carried a flat fee of .75% will also
have breakpoints at $500 million and $1 billion in assets. In addition, the .01%
administrative fee has been eliminated on all funds.

NERVOUS MARKET CALLS FOR COOL HEAD

A bout of market jitters can leave many investors feeling a bit nervous. But at
Berger we believe that the best advice can be found in a few time-proven points:

- -    INVEST FOR THE LONG TERM--Successful investors are patient. Stocks may tend
     to be more volatile over the short term, but over time, stocks have
     outperformed other types of investments. Historically, the stock market
     spends more time going up than down.

- -    STAND FIRM--It's just human nature--market volatility translates to nervous
     investors. But it's important to avoid making rash decisions rooted in
     emotion rather than fact. It isn't always easy, but to reach your financial
     goals, we believe it's best to resist the temptation to make short-term
     moves.

- -    INVEST REGULARLY--Dollar cost averaging--investing at regular intervals can
     help you put volatility to work for you. During market dips you pay less
     for your fund shares, which can help to lower the average price you pay for
     shares over time.(7)

Meeting Your Expectations Our goal of achieving consistently competitive
performance is matched by a second, equally important goal of meeting your
service needs. You can let me know what's on your mind by emailing me at
[email protected]. I want your investment experience with us to be
successful.

As always, we value the trust you have placed in us. In the months to come, I
will keep you updated on our progress. We look forward to helping you reach
your investment goals through the year 2000 and beyond.

                                               Sincerely,

                                               /s/ Jack R. Thompson

                                               JACK R. THOMPSON
                                               PRESIDENT


Investment returns and principal value will fluctuate so shares, when redeemed,
may be worth more or less than their original cost. The Berger Funds may invest
in IPO's that may significantly impact performance.

(1)  Past performance does not guarantee future results.
(2)  The Standard & Poor's 500 Index is a broad-based measurement of changes in
     stock market conditions based on the average performance of 500 widely held
     common stocks. The Index is unmanaged, and investors cannot actually make
     investments in the Index. All comparisons to the Index are based on
     year-to-date performance through 9/30/99.
(3)  Morningstar proprietary ratings reflect historical risk-adjusted
     performance as of 9/30/99 and are subject to change every month. Ratings
     are calculated from the funds' 3-, 5- and 10-year average annual returns
     (if applicable) in excess of 90-day Treasury bill returns with appropriate
     fee adjust ments and a risk factor that reflects fund performance below
     90-day T-bill returns. Berger Growth and Income Fund received 4, 3 and 4
     stars among 3,210, 2,010, and 751 domestic equity funds for the 3-, 5- and
     10-year periods, respectively. Berger New Generation Fund received a 5-star
     rating out of 3,210 domestic equity funds for the three-year period. The
     top 10% of the funds in a broad asset class receive 5 stars, the next 22.5%
     receive 4 stars, and the next 35% receive 3 stars. Given Berger New
     Generation Fund's focus on leading-edge companies and those in rapidly

PORTFOLIO MANAGER COMMENTARY                                WILLIAM F. K. SCHAFF

PERFORMANCE

The Berger Information Technology Fund (the "Fund") gained 29.53%(1) (Investor
Shares) and 31.30% (Institutional Shares) for the period from March 1, 1999 to
September 30, 1999. This performance compared very favorably with that of
broader market indices such as the Standard & Poor's (S&P) 500 Index,(2) Russell
2000 Index(3) and Wilshire 5000 Index,(4) which gained 4.38%, 9.94% and 4.56%,
respectively.

Our returns lagged some of the broader technology indices, however, because our
Fund has a heavier weighting in information technology (IT) services, software
and hardware. Among our peer group, the highest returns were earned by funds
that invest in semiconductors, which have been the best performing technology
segment this year. Despite our overweighting in the IT sector, we remain
confident with our portfolio positioning and company exposure. The IT industry
tends to be more defensive and less cyclical than the semiconductor and related
groups.

YEAR IN REVIEW

The best performers among our larger holdings were LSI Logic, Nextel
Communications, Texas Instruments, Siebel Systems and Hewlett-Packard. LSI and
Texas Instruments are benefiting from strong chip demand. Wireless and
networking applications are the strongest demand pulls. An example of this is
Nextel Communications, a strong, independent wireless company that has been the
subject of takeover rumors for some time. Siebel Systems continued to show
strong revenue growth from sales of its leading customer relations management
(CRM) software. Hewlett-Packard's price performance was partly a result of the
spin-off of its test and measurement business. Company management has found ways
of increasing shareholder value over time.

The negative performance of three stocks dragged down Fund performance this
period. Compaq was our biggest disappointment. This leading PC vendor continued
to struggle with change and management uncertainty. Mindspring, a leading
Internet service provider, is facing aggressive pricing competition for its
services. AXENT Technologies is one of many struggling security software
companies. Their business is focused on corporate security, and we believe this
area will rebound in the year 2000.

Portfolio turnover this period was very low--just over 50% annualized. This is
substantially less than many general technology funds and has helped minimize
taxable gains to our shareholders.

LOOKING AHEAD

With the explosive growth in e-commerce and Web-based business models, it is not
surprising that one of the biggest challenges facing most traditional businesses
is finding a way to compete in the "new economy." We believe that one of the
fastest growing areas for IT-related companies will be the ever-increasing use
of IT services and software in traditional businesses. While many projects will
be justified by management on a rate of return analysis, many others will be
undertaken purely for strategic reasons, such as maintaining or increasing the
company's competitive edge. We expect areas of demand to include systems
management software like that offered by BMC Software and Computer Associates.
We also look for a rebound in enterprise resource planning (ERP) and related
vertical applications. ERP is currently led by SAP and Oracle. Vertical
applications, such as supply chain management (SCM) and CRM software, should be
in strong demand. Companies potentially benefiting from this demand include i2
and Siebel Systems.

Another area we see as fast-growing is enterprise applications integration (EAI)
software, which is used to tie in multiple platforms and different applications.
Many recent Initial Public Offerings (IPOs) have been in this area.

We also believe that e-commerce development and services will continue to be
hot. The general category is too broad to discuss here, but some of the winners
should be the leading networking companies such as Cisco, along with e-commerce
vendors such as BEA Systems.

We strongly believe that 2000 will be the year for IT companies. Once free of
the constraints of Y2K budgets, applications and service firms should see a
buildup of backlog and a strong push toward new development projects that
enhance corporate productivity. We are optimistic that IT-related companies will
be the biggest beneficiaries within the broader technology spectrum. We are
still very bullish in our long-term outlook because we believe that IT will
remain one of the fastest growing segments in the North American economy.

1. Past performance does not guarantee future results. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

2. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

3. The Russell 2000 Index is an unmanaged index, with dividends reinvested,
which consists of the common stocks of 2000 U.S. companies. It is a generally
recognized indicator used to measure overall performance of small company
stocks. One cannot invest directly in an index.

4. The Wilshire 5000 Index measures the performance of all U.S.-headquartered
equity securities with readily available price data. More than 7,000
capitalization weighted security returns are used to adjust the index. One
cannot invest directly in an index.

PORTFOLIO MANAGER COMMENTARY                                  MARK S. SUNDERHUSE

PERFORMANCE

The Berger New Generation Fund (the "Fund") had an outstanding year, registering
a total return of 110.82%(1) (Investor Shares) and 110.98%(1) (Institutional
Shares) for the 12 months ended September 30, 1999. This significantly outpaced
the 27.80% gain for the Standard & Poor's (S&P) 500 Index(2) and the 19.07% gain
for the Russell 2000 Index(3) for the same period.

YEAR IN REVIEW

After taking over the Fund in February 1999, we have positioned the Fund in
sectors and industries that buffered it from the market doldrums of the last
quarter, which greatly enhanced our return over the year. In all sectors, we
continue to look for innovative companies with superior management skills,
financial strength and a definitive business plan with measurable milestones.

Our emphasis on technology has served shareholders well. More than half of total
Fund assets have been invested in technology stocks since the Fund's fiscal year
began. But, unlike some other aggressive growth funds, we look for potentially
high-growth technology companies across all industries in order to broaden and
diversify our Fund's technology reach. There are valuable technologies to be
found in energy, healthcare and other sectors. New technologies in the steel
industry, for example, make the metal harden faster and resist corrosion better.
We try to avoid what we call "commodity" technologies. These are technologies
that can easily be duplicated allowing competition to drive prices down. Memory
chips, for example, are a commodity technology.

Within the technology sector, we've seen very strong performance from
telecommunications equipment firms, telecommunications service providers and
semiconductor companies that produce communication chips. Key contributors over
the year included At Home, Citrix Systems and Sun Microsystems.

In the Internet arena, we bought very selectively during the year. Although the
Internet is here to stay, not every Internet company is. We have focused on what
we call the Internet enablers, which are companies that make the technologies
that enable the Internet to work. We look for companies that we believe will own
their share of the market in the future. In the "dot-com" area, we also
selectively seek companies that can achieve market leadership and dominate their
market over the next few years. This includes eBay, which provides on-line
auctions, and eToys, an on-line retailer of toys.

We also saw strong performance in the energy sector. On September 30, 1999, we
had 12.1% of Fund net assets invested in energy compared with 1.4% a year
earlier. One stock that contributed to performance is the natural gas
exploration and transportation company, Western Gas Resources.

Another area of strong performance was in the healthcare sector. The Laser
Vision Center, a laser vision correction company, and Guidant, a medical device
company, boosted Fund performance. Another strong performer during this year has
been Genentech, a biotechnology firm that has a strong product pipeline.

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

LOOKING AHEAD

We're cautiously optimistic about the economy and the market going forward.
Investors today are very knowledgeable about the market and much more
comfortable being in it. We think that means investment capital will continue to
flow into and fuel the market.

We believe the final quarter of the year will continue to be one of uncertainty.
However, we see investment opportunity in the U.S. and internationally once we
enter the year 2000, especially for software companies that have languished
recently. We've already seen some recovery in the stocks of these companies, and
we believe this will continue after the new year.

1. Past performance does not guarantee future results. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

2. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

3. The Russell 2000 Index is an unmanaged index, with dividends reinvested,
which consists of the common stocks of 2000 U.S. companies. It is a generally
recognized indicator used to measure overall performance of small company
stocks. One cannot invest directly in an index.

PERFORMANCE

The Berger Select Fund (the "Fund") had a total return of 53.06%(1) for the
year ended September 30, 1999, which significantly outperformed the 27.80%
return of the Standard & Poor's (S&P) 500 Index,(2) for the year.

Our Fund focuses on growth companies of all market cap sizes. We take larger
positions in a smaller number of stocks, generally holding a core portfolio of
20 to 30 stocks. We select stocks using investment ideas that are considered to
be the best of Berger--ideas about companies that we believe have the best
opportunity and potential to outperform their peers and the market.

YEAR IN REVIEW

Among the key reasons why our Fund nearly doubled the return of the S&P 500
Index this past year was our stock selection in the technology and energy
sectors.

We started focusing on the energy sector mid first quarter 1999 and held a
strong position in this sector in the quarter ended September 30. Although
energy stocks were down during that quarter, they delivered a solid, positive
return year-to-date. We believe that there are very strong fundamentals in
energy. Oil prices have gone up because of a decrease in oil production and an
increase in demand attributable to recovering world economies. We continue to
like the growth potential in the energy sector and in energy companies such as
ENSCO International and Burlington Resources.

Over the year, we substantially increased our weighting in technology--from 27%
of Fund net assets on September 30, 1998, to 55% one year later. This heavy
weighting boosted Fund performance, particularly during the quarter ended
September 30, 1999, when technology stock prices continued on the upward trend
that began in June. We believe in the long-term prospects for technology. We
remain convinced that growth prospects for the Internet infrastructure are
explosive, and we continue to focus on telecommunication and broadband
companies. These companies provide the plumbing that enables broad acceptance of
Internet applications and services. The Fund benefited from strong performances
over the year by technology leaders such as Juniper Networks, Motorola and
Cisco Systems.

Healthcare is our second largest sector, making up just over 12% of our Fund's
total portfolio. Genentech, a biotechnology company, aided fund performance. We
believe that this firm has a strong product pipeline and bright prospects for
future growth.

Among other Fund sectors, the financial sector significantly underperformed. One
stock that turned in particularly disappointing results was Charles Schwab.
Schwab's decline was primarily due to the market's short-term investor concerns
about rising interest rates and year 2000 issues. We believe that the long-term
prospects for Schwab are positive, however, and we look for the company to excel
in 2000.

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

LOOKING AHEAD

We expect near-term market volatility for two reasons. First, rising interest
rates continue to nag the equity market. Second, investors are still somewhat
concerned that there will be problems during the transition to the year 2000. As
a result of these factors, investors may once again gravitate toward large cap
companies, which they perceive to be safer and more stable investments in bumpy
markets. Over the long term, however, robust U.S. economic growth and the
continuing recovery of international economies should provide a solid backdrop
for strong corporate earnings.

PERFORMANCE

For the fiscal year ended September 30, 1999, the Berger Small Company Growth
Fund (the "Fund") had a total return of 62.78%(1) (Investor Shares). This
significantly outdistanced the gains registered by the Russell 2000 Index(2)
and the Russell 2000 Growth Index(3), which were 19.07% and 32.63%,
respectively over this time period.

Just eight days into this fiscal year, small cap stocks, which had languished in
a bear market, staged an impressive rebound that lasted through the fourth
quarter 1998. Technology stocks led the way. As a group, small cap stocks
performed in step with large cap stocks from October 8, 1998 until mid-January
1999 when interest rate fears crept into the marketplace. Small caps then
dramatically underperformed large caps through March.

Between April and June, small caps (as measured by the Russell 2000)
outperformed large caps (as measured by the S&P 500 Index(4)) by nearly 8%. This
was the best quarterly outperformance of small caps since the fourth quarter
1992 and was attributable to the more attractive relative valuations of small
caps compared to large caps after a very difficult first quarter 1999.

In the quarter ended September 30, the stock market faltered on renewed interest
rate fears, and both small and large cap stocks performed poorly.

YEAR IN REVIEW

Despite this up and down year for small cap stocks, our Fund was able to
considerably outperform its benchmarks mainly due to stock selection.

The Fund remains heavily weighted in industries where growth prospects are the
most visible and consistent. Technology, our largest sector, continues to have
the greatest long-term growth fundamentals. We believe that the growth prospects
are explosive for the Internet infrastructure in particular. Therefore, we
continue to focus on telecommunication and broadband companies, which provide
the plumbing that enables broad acceptance of Internet applications and
services. Similarly, companies such as Powerwave Technologies, which supplies
components for wireless communications, have been strong holdings.

We have seen a pick-up in the information technology services group. We believe
some large contract orders for the Internet-related companies may revive this
Y2K depressed group. Semiconductor stocks continued to show solid revenue growth
and improving Asian economies should help sustain this trend.

Our Fund lowered it exposure to the healthcare group over this fiscal year.
Uncertainty surrounding prescription drug benefits and the government's impact
on drug pricing kept a lid on these stocks. One bright spot in the sector was
biotechnology stocks. Emerging biotechnology companies such as Biocryst
Pharmaceutical and Cephalon boosted Fund performance.

Our energy weighting contributed to the Fund's outperformance in the first six
months of 1999. Although there are worries that OPEC will irrationally increase
oil production, we remain positive on the long-term supply/demand fundamentals
within the sector.

Within the consumer group, radio stocks continue to be solid performers. The
environment for radio advertising was robust in 1999, and we expect this group's
strong fundamentals to carry into next year.

LOOKING AHEAD

Going forward, we continue to favor the technology sector, particularly the
telecommunication and broadband infrastructure companies that support the
Internet. We recognize that the fear of Y2K slowdown within the enterprise
software group is probably fully discounted and we believe that the
Internet-enabler software companies, which are companies that make the
technologies that enable the Internet to work, will be strong performers into
next year. We expect semiconductors to continue their strong fundamentals into
next year as well.

We remain cautiously optimistic about the market as we enter the final quarter
of 1999. The U.S. economy is undeniably robust and international economies are
picking up. We expect productivity to continue to grow and to fuel low
inflationary growth into 2000. The Federal Reserve Board left interest rates
unchanged at their early October meeting. But, if inflation picks up, the Fed
may raise rates again. However, inflation fears have been stemmed year to date.

We would need to see a period of greater operating profit growth for small caps
in order for them to outperform their large cap peers. We believe our bias
towards technology will be beneficial as we enter year 2000. Global economies
appear to be strengthening in concert, which will benefit technology stocks
since they often garner over 50% of earnings internationally.

PERFORMANCE

The Berger Small Cap Value Fund (the "Fund") had a total return of 24.69%(1)
(Investor Shares) and 25.18%(1) (Institutional Shares) for the year ended
September 30, 1999. This outperformed the 19.07% return registered by the
Russell 2000 Index(2) over the same period.

The year ended September 30, 1999, marked the sixth straight year of relative
underperformance of the Russell 2000 versus large cap indices. We believe this
disparity is largely a function of excessive market appreciation in the large
cap technology stocks that dominate the NASDAQ 100 and in the 50 largest
companies in the S&P 500 Index.

YEAR IN REVIEW

Our best-performing sector this year was energy. Commodity prices rebounded and
several issues returned more than 100% over the last 12 months. We used the
strength in the sector to reduce holdings in such names as Newfield Exploration
and BJ Services and to add names where we saw further upside potential, such as
Marine Drilling Companies and Key Energy Services.

In the communications sector, we enjoyed strong gains from Centennial Cellular
and Jones Intercable, as well as from cellular infrastructure providers REMEC
and Sawtek. These stocks rebounded as demand increased for broadband and lower
cell phone prices.

Since the beginning of our fiscal year, we have decreased our exposure to fallen
growth stocks, which are stocks that are trading near or at their all-time lows,
because we saw limited investment opportunities. The exceptions were stocks in
the information technology (IT) services industry. Many companies delayed large
IT projects until early next year in order to prepare for the Y2K changeover.
During this period, IT companies corrected as much as 50% to 60%. We viewed this
as a buying opportunity because worldwide demand of this service is expected to
double by 2003. Names we have added in this sector include Interim Services,
Romac International and Computer Horizons.

The most disappointing stocks have been in the financial sector, specifically
the banks and thrifts industry. Their earnings growth continues to meet or
exceed expectations, but their prices do not. Many of these companies are
aggressively buying back their stock and raising their dividends, and industry
consolidation continues. The one exception is in the real estate investment
trusts (REIT) industry, where we continue to find attractive valuations. REITs
traditionally sell at yields equivalent to 10-year Treasuries, which are
currently 5.9%. The average current yield of REITs held by the Fund is 8.1%.
This industry is clearly out of favor, yet many companies boast clean balance
sheets, quality assets and trade at a significant discount to their net asset
values. We continue to add to names such as Home Properties of New York and
Prentiss Properties Trust.

Another sector now showing up on our radar screen is healthcare. A cloud of
legislation hovering over Washington created uncertainty in this sector and
caused a widespread sell-off. But values are beginning to appear. We are unsure
as to the exact timing of a resolution of problems in this sector, but we are
certain that a number of companies will emerge from the shakeout stronger than
ever. In order to capitalize on what we view as temporary issues, we are
focusing on finding quality companies with strong balance sheets that are
capable of weathering the storm and solidifying their positions as industry
leaders. One company we have added is Omnicare.

LOOKING AHEAD

We reflect on fiscal 1999 with mixed emotions. We are pleased with the Fund's
outperformance versus its benchmark, yet we remain frustrated with the continued
apathy the market has shown toward the small cap sector. As we enter the seventh
year of underperformance by small cap stocks, we reiterate our belief that the
best long-term returns are generated by investments in this area. Historically,
when the general market turns from larger companies to smaller ones, small cap
stocks perform exceedingly well. We are confident that history will repeat
itself. We will continue to manage the Fund according to the same small cap
value philosophy we have applied for 30 years and await the return of capital to
the small cap sector.

(1.) Past performance does not guarantee future results. The investment return
     and principal value of an investment will fluctuate so that an investor's
     shares, when redeemed, may be worth more or less than their original cost.

(2.) The Russell 2000 Index is an unmanaged index, with dividends reinvested,
     which consists of the common stocks of 2000 U.S. companies. It is a
     generally recognized indicator used to measure overall performance of small
     company stocks. One cannot invest directly in an index.

PERFORMANCE

For the 12-month period ended September 30, 1999, the Berger Mid Cap Growth Fund
(the "Fund") had an outstanding total return of 102.76%,(1) which was four times
higher than the 25.44% total return of the Standard & Poor's (S&P) MidCap 400
Index.(2)

As we began our fiscal year in October 1998, the price of mid cap stocks was
depressed, the result of a summer/fall market correction. Beginning October 8,
1998, and extending through the end of that year, mid caps bounced back in
tandem with large caps. Technology stocks led the way.

From January through March 1999, only large cap stocks performed well, an echo
of 1998 market trends. During this period, stocks in the S&P MidCap 400 Index
fell 7%, while larger cap stocks in the S&P 500 Index(3) rose 4%.

The market broadened in the second calendar quarter 1999, and both mid and small
cap stocks registered solid relative performance. As a group, mid caps had twice
the gains of large caps. The S&P MidCap 400 Index gained 14% versus the S&P 500
Index's gain of 7%.

In the quarter ended September 30, 1999, the stock market faltered on renewed
interest rate fears, and both mid cap and large cap stocks performed poorly.

YEAR IN REVIEW

Despite this up and down year for mid cap stocks, our Fund was able to
considerably outperform its benchmark mainly because of stock selection.

The Fund remains heavily weighted in industries in which growth prospects are
the most visible and consistent. Technology, our largest sector, continues to
have the best long-term growth fundamentals. We believe the growth prospects are
explosive for the Internet infrastructure in particular. Therefore, we continue
to focus on telecommunication and broadband companies, which provide the
plumbing that enables broad acceptance of Internet applications and services.
Both Verisign, in Internet infrastructure, and Applied Micro Circuits, in
telecommunications, have been strong holdings.

We have seen a pick-up in the information technology services group. We believe
some large contract orders for Internet-related companies may revive this
Y2K-depressed group. Semiconductor stocks continued to show solid revenue
growth, and improving Asian economies should help sustain this trend.

Our Fund lowered its exposure to the healthcare group over this fiscal year.
Uncertainty surrounding prescription drug benefits and the government's impact
on drug pric ing kept a lid on these stocks. One bright spot in the sector was
biotechnology stocks. Among our holdings, Medimmune and IDEC Pharmaceuticals
helped boost Fund performance.

Our energy weighting contributed to the Fund's outperformance in the first six
months of 1999. Although there are worries that OPEC will irrationally increase
oil production, we remain positive on the long-term supply/demand fundamentals
within the sector.

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

LOOKING AHEAD

Going forward, we continue to favor the technology sector, particularly the
telecommunication and broadband infrastructure companies that support the
Internet. We recognize that the fear of Y2K slowdown within the enterprise
software group is probably fully discounted and believe the Internet-enabler
software companies, which are companies that make the technologies that enable
the Internet to work, will be strong performers into next year. We expect
semiconductors to continue their strong fundamentals into next year as well.

We remain cautiously optimistic about the market as we enter the final quarter
of 1999. The U.S. economy is undeniably robust and international economies are
picking up. The Federal Reserve Board left interest rates unchanged at their
early October meeting. But, if inflation picks up, the Fed may raise rates
again. However, inflation fears have been stemmed year to date.

The growth prospects, relative valuations and greater liquidity of mid cap
stocks make them a very attractive segment of the market going forward. We
believe that our Fund's bias toward mid cap technology companies will be
beneficial as we enter 2000. Global economies appear to be strengthening in
concert, which is a positive sign for technology companies because they often
garner more than 50% of earnings internationally.

(1.) Past performance does not guarantee future results. The investment return
     and principal value of an investment will fluctuate so that an investor's
     shares, when redeemed, may be worth more or less than their original cost.

(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.

(3.) The S&P 500 Index is an unmanaged index, with dividends reinvested, which
     consists of the common stocks of 500 publicly traded U.S. companies. It is
     a generally recognized indicator used to measure overall performance of the
     U.S. stock market. One cannot invest directly in an index.

PERFORMANCE

We are pleased to report that in its first full year, which ended September 30,
1999, the Berger Mid Cap Value Fund (the "Fund") gained 31.12%(1) compared with
25.44% for the Standard & Poor's (S&P) MidCap 400 Index,(2) 10.00% for the S&P
Midcap Value Index(3) and 27.80% for the S&P 500 Index.(4) Our Fund outperformed
these indices primarily because we purchased severely depressed stocks in the
technology and energy sectors in late 1998 and early 1999. Subsequently, we had
strong appreciation in those stocks.

The S&P MidCap indexes underperformed large cap market indices for the year
because larger growth stocks continued their multiyear run up in prices.
Although the S&P MidCap 400 Index outpaced the S&P 500 Index every year (except
1990) from 1988 through 1993, it has trailed the S&P 500 Index every year since
then. This period of underperformance has resulted in the most attractive
relative valuation levels for mid cap and small cap value stocks we've seen in
this decade. Historically, after similar extended periods of underperformance,
value stocks have had several years of relatively good returns. This could occur
in the coming year, especially since world economic prospects are positive.

YEAR IN REVIEW

Since March 31, the biggest change in our sector weighting was the increase of
energy holdings from 8.8% of Fund net assets to 11.8%. This increase was due
primarily to appreciation in the price of oil and gas producer stocks we
purchased in late 1998/early 1999. At that time, energy prices had fallen to
about one-half current levels. Prices of some of these stocks, including
Mitchell Energy and Development, picked up as much as 90% between March 31 and
September 30.

The financial sector remains our largest sector, constituting 27.1% of the
portfolio. Unfortunately, financial stocks generally underperformed as interest
rates unexpectedly continued to rise. Ironically, in almost all cases, earnings
have grown in line with expectations, and many of these companies are raising
dividends and buying back stock. We expect earnings to be favorable as long as
the economy is strong. With valuations depressed to levels not seen in several
years, we used the period of weakness to add to our regional bank holdings. Bank
stocks haven't been this cheap since 1994. They subsequently outperformed in
1995 and 1996 as interest rate pressure eased. Real estate investment trusts
(REITs) also continue to be an area of emphasis as earnings and dividends are
growing, current yields are over 9%, and the stocks are selling somewhat below
net asset value.

Technology is our second-largest sector. Our practice of ferreting out fallen
growth stocks has been especially rewarding here. The growth pattern of
technology companies can be bumpy. As they recover from the bumps and return to
their secular growth paths, the stocks of these companies often regain premium
valuations and have explosive appreciation. At this point, we usually liquidate
part or all of our positions in the stocks. For example, we reduced holdings in
Analog Devices, Tellabs and Methode Electronics and eliminated Sanmina after
achieving gains of 100% to 300%. If these companies experience temporary
problems again in the future, we could reinvest. In the meantime, some of the
proceeds of these sales were deployed to other issues that more recently fell
into what we think is only temporary market disfavor such as Andrew, Aspect
Telecommunications, Comdisco and Keane. When we purchased these stocks, all were
down at least 25% from their recent highs; three were down more than 60%.

LOOKING AHEAD

Most stocks are down about 20% from their highs of last year and are reflecting
more reasonable valuations. Because of this price correction, we have positive,
though modest, expectations for the market. Moreover, international economic
recovery is more solidly in place, and we still anticipate an end to the rise in
interest rates.

We are more comfortable with mid and small cap value stocks than we are with the
overall market. The poor third-quarter performance of these issues improved
their relatively favorable risk/reward relationships. As a reflection of their
relative attractiveness, our portfolio companies, as of September 30, were
priced under 18 times estimated 1999 earnings compared with 27 times for the S&P
500 Index. And, if we have global economic growth, earnings comparisons for our
stocks should be favorable. We remain confident in following our discipline of
investing in relatively undervalued, well-financed companies with good growth
prospects and above-average dividends.

1. Past performance does not guarantee future results. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

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.

3. The S&P MidCap Value Index is an unmanaged index, with dividends reinvested,
and is generally representative of the market for value stocks for mid-sized
companies. One cannot invest directly in an index.

4. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

PERFORMANCE

The Berger 100 Fund (the "Fund") had a solid total return of 38.96%(1) for the
year ended September 30, 1999, which outpaced the 27.80% return for the Standard
& Poor's (S&P) 500 Index(2) and the 25.44% gain registered by the S&P MidCap 400
Index(3) for the same period.

It has been a roller coaster year for the stock market. During the first few
months of our fiscal year (October 1998--early January 1999), the market staged
a broad rally that benefited the mid to large cap growth stocks favored by our
Fund. In mid-January, however, the market narrowed, and the very largest cap
companies once again dominated performance. The market was mixed during the
quarter ended June 30, largely as a result of growing concern about rising
interest rates and hints of potential inflation. In the last quarter of our
fiscal year, the market was nervous about interest rates once again and seemed
to lack direction. Most sectors and market indices were down.

YEAR IN REVIEW

Our Fund was able to perform against this difficult economic backdrop for two
reasons. First, we had strong performances from some individual stocks in our
portfolio. Second, we were heavily weighted in the technology sector.

Our largest sector is the technology sector, which includes telecommunications,
Internet, computer software and semiconductor manufacturers. Technology has
handily beaten all other sectors for the year and had the best overall
performance of any sector in the quarter ended September 30. Several of our
technology holdings turned in strong gains for the year, including Microsoft,
Intel, Texas Instruments and Xilinx. We continue to believe in the long-term
prospects for technology because of the vital role that it plays in the
operations of businesses around the world.

Energy was our second-best performing sector, even after a late sell-off in the
quarter ended September 30, 1999, that was attributable to investors focusing on
near-term earnings revisions rather than on industry growth prospects over the
next two years. Compared with the S&P 500 Index, we have been slightly
overweighted in this sector all year and ended the year with a total of 7.2% of
Fund net assets committed to energy stocks. We believe that there are strong
fundamentals in energy. Oil prices have gone up because of a decrease in oil
production and an increase in demand attributable to recovering world economies.
We continue to like the growth potential in the energy sector.

Among other Fund sectors, the healthcare and consumer groups had mixed results
over the year. We had solid performance from Genentech, a large biomedical
company with a strong product pipeline, but had poor performance from American
Home Products, a company currently facing litigation surrounding its Fen-Phen
drug, which is used to treat obesity. Among the consumer-related stocks in our
portfolio, Royal Caribbean Cruises and Best Buy Co. turned in strong
performances for the year.

Most stocks in the financial sector underperformed over the year primarily
because of the market's concerns about rising interest rates and year 2000
issues. Among our financial stocks, leading on-line broker Charles Schwab was
hit hard. We believe that the long-term prospects for Schwab are positive,
however, and we look for this company to excel in 2000. With our financial
holdings reduced to just over 3% of Fund net assets, we are now underweighted in
this sector.

LOOKING AHEAD

We expect that two factors could create market volatility in the near term. The
first is rising interest rates, which continue to nag the equity market. The
second is the market's focus on year 2000 issues, which we believe will cause
investor concern the rest of this year. The result may be that investors crowd
into large cap companies, which are perceived to be safer and more stable
investments. For the long term, the robust U.S. economic growth and the
continuing recovery of international economies should provide a solid backdrop
for strong corporate earnings.

1. Performance figures are based on historical results and are not intended to
be indicative of future performance. The investment return and principal value
of an investment will fluctuate so that an investor's shares, when redeemed, may
be worth more or less than their original cost.

2. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market.  One cannot invest directly in an index.

3. 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.

PERFORMANCE

The Berger/BIAM International Fund (the "Fund") had a total return of 29.64%(1)
for the year ended September 30, 1999 compared to 31.32% for the MSCI EAFE
Index.(2)

Global equity markets began the fiscal year last October with strong
performances, prompted primarily by interest rate reductions in both the U.S.
and Europe. In January, European markets benefited from the introduction of the
new single currency, the euro, and Japanese markets enjoyed positive investor
sentiment as a result of overseas buying. Markets in the rest of the Pacific
region turned in mixed results largely due to a pick-up in sentiment towards
Japan and the phenomenon of western multinationals seeking stakes in Asian
companies.

By the second calendar quarter 1999, the new euro currency received negative
press following a steady decline against the U.S. dollar and other major
currencies. We believe the euro is acting as a catalyst for change, however, and
increasing competition across Europe.

We remained extremely cautious about investing in Southeast Asia this year, even
though the acute financial crisis appears to be over. Although Japanese figures
have been strong, we believe Japan is a stock-picker's market because not all
companies will deliver on the promises they are making to investors. As a
result, we added to our Japanese holdings over the year on a stock-by-stock
basis.

YEAR IN REVIEW

Two groups of stocks led our portfolio higher this fiscal year: those in the
Growth in Telecommunications theme and Japanese-quoted stocks, particularly
those in our Technological Innovation theme.

The most notable performers among Growth in Telecommunications stocks for the
year were German-quoted Mannesmann and NTT Mobile Communications Network. NTT
Mobile Communications Network was among our strongest contributors during the
past six months. The company is Japan's dominant cellular phone operator and its
stock rose on the belief that the company will benefit from growing demand for
data transmission services through cellular phones. Two holdings - UK-quoted
Vodafone AirTouch Group and Telecom Italia - were involved in the merger and
acquisition activity that engulfed global telecommunication companies earlier in
the year.

Japanese-quoted stocks began their comeback early in our fiscal year and have
been our leading performers since March 31. Electronics exporters, in
particular, did well on the back of buoyant global demand for PCs, copiers,
printers, mobile phones and their related components. Leading the way was Murata
Manufacturing, which raised its net profit forecast by 25% for the coming year
and announced plans to increase its production capacity in response to demand
for the electronic components used in cellular phones. Semiconductor
manufacturer Rohm also increased its profit projections on the heels of
higher-than-expected sales of circuits for mobile communications equipment.

The primary reason we slightly lagged our benchmark for the year was the
performance of stocks in the Positive Banking Environment theme. After
strengthening early in the year, these stocks faltered the second half, largely
due to a negative interest rate environment. (Both the U.S. Federal Reserve
Board and the Bank of England raised interest rates in response to upward
pressure on inflation rates attributable to a stronger global economy.) One
example of the impact of interest-rate concerns was the response to National
Australia Bank. Even though the bank released results that were greeted
positively by analysts, its stock price fell.

LOOKING AHEAD

The pace of global economic change continues to accelerate and all of the
world's major economic regions are expanding. Europe is benefiting from the
combined effects of a monetary policy biased towards stimulating growth, a
competitive currency and general global recovery. The latest economic data in
the UK also reveal a significant acceleration in growth. Surveys show that
business confidence is increasing while unemployment is falling. Economic
activity in the Pacific Region continues its strong rebound.

As global growth gathers pace, we have been paying close attention to
developments in Japan. We are gradually beginning to be convinced that this
year's economic recovery may be sustainable. But, while many Japanese companies
are making very encouraging statements about restructuring, there is significant
execution risk for investors who are looking to take advantage of these changes.
There is a danger that Japanese companies may avoid making painful decisions
simply because their stock prices have recovered from their lows. Having said
that, we believe that there is real and substantial restructuring underway in
Japan and we are attempting to identify companies that are in the forefront of
this change.

PERFORMANCE

The Berger Growth and Income Fund (the "Fund") had a total return of
38.67%(1) for the year ended September 30, 1999. This was significantly
higher than the 27.80% gain registered by the Standard & Poor's (S&P) 500
Index(2) for the same period.

YEAR IN REVIEW

It was a roller coaster year for large, high-quality growth companies. After two
Federal Reserve Board interest rate cuts in the fourth calendar quarter 1998,
the S&P 500 and the Nasdaq soared to new highs. Strong economic growth and
moderate inflation in the first calendar quarter 1999 resulted in double-digit
gains for the S&P 500 Index. However, fears of rising interest rates and
potential inflation caused investors to move away from large growth stocks in
the quarter ended June 30. The third calendar quarter of 1999 was highly
volatile, resulting in negative returns for both our Fund and its benchmark
index.

Nevertheless, the Fund was able to deliver an outstanding gain and significantly
outperform the S&P 500 Index for the year. The key reason was our overweighting
in the technology sector, which includes telecommunications, cable and
computers. We continue to believe in the long-term prospects for technology.
Technology is the largest sector in the Fund and, over the year, we increased
the percentage of Fund net assets invested in this sector from 27.4% on
September 30, 1998, to 44.3% on September 30, 1999. Strong performances were
turned in from technology companies such as Intel, Microsoft, Nokia and Sun
Microsystems.

In the quarter ended September 30, 1999, the Fund benefited particularly from
strong performances by companies in other technology industries, especially
telecommunication and communication services. These included Sprint PCS Group,
EchoStar Communications and Clear Channel Communications, which now owns the
largest number of radio stations in the U.S. as well as a number of outdoor
advertising displays.

Early in the year, we identified signs of expansion in the energy sector, so we
increased our weighting. We believe that there are very strong fundamentals in
the energy sector. Oil prices have gone up because of a decrease in oil
production and an increase in demand attributable to recovering world economies.
We continue to like the growth potential in this sector. Among our best
performers in this sector were Halliburton and ENSCO International.

Despite the healthcare sector's poor performance during the last year, our Fund
had success in this sector primarily because of our biotechnology stocks. Late
last year, we identified several strong companies. Amgen has been one of the
most successful companies in the portfolio because of its strong drug pipeline.
Another company we added was Genentech, a biotechnology company that also has a
strong pipeline of new drugs, including Herceptin, used to treat metastatic
breast cancer, and Rituxan, used to treat non-Hodgkin's lymphoma. American Home
Products has been a strong performer for the first half of the year, but the
stock was hit hard in the third quarter 1999 because of the litigation
surrounding its Fen-Phen drug, which was used to fight obesity.

We have continued our underweighting in the Financial sector. This year the
sector's performance has been hit hard because of the market's concerns about
rising short-term interest rates. In addition, the poor performance in this
sector in the third quarter 1999 was attributable to the market's global effects
regarding Y2K. Those stocks most affected include First Tennessee National and
Charles Schwab. Although we expect some volatility in this sector for the
remainder of the year, we believe the long-term prospects of these individual
companies are good, and we look for them to excel in 2000.

LOOKING AHEAD

We expect that two factors could create market volatility over the near term.
The first factor is rising interest rates, which continue to nag the equity
market. The second factor is the market's focus on year 2000 issues that we
believe will cause investor concern the rest of the year. The result may be that
investors crowd into large cap companies, which are perceived to be safer and
more stable investments. For the long term, the robust U.S. economic growth and
the continuing recovery of international economies should provide a solid
backdrop for strong corporate earnings.

1. Past performance does not guarantee future results. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

2. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

PERFORMANCE

The Berger Balanced Fund (the "Fund") had a total return of 39.41%(1) for the
year ended September 30, 1999. This significantly outpaced the 27.80% total
return registered by the Standard & Poor's (S&P) 500 Index(2) over the same
period. We believe this performance is attributable to our bottom-up style of
investing (company-by-company stock selection) and to our dynamic asset
allocation process, which holds Fund assets in income-producing fixed-income
securities as we uncover stocks that offer growth potential.

YEAR IN REVIEW

It was a roller coaster year for the U.S. stock market. Unfounded fears of a
recession in late 1998 caused stock prices to gyrate wildly. Two interest rate
cuts by the Federal Reserve Board in the fourth quarter of 1998 helped fuel a
powerful rally that carried stocks (as measured by the S&P 500 Index) to record
highs by May 1999. Between then and September 30, however, the market was flat
to down, largely in response to concerns about an increase in inflation and
rising interest rates. Tight labor markets and a weak U.S. dollar added to
investor anxiety. In response to a strong U.S. economy and recovering economies
overseas, the Federal Reserve Board increased interest rates once during this
period.

As of September 30, 1999, the Fund's net assets were allocated as follows: 58%
equities, 33% fixed income and 9% cash equivalents, which was similar to the
allocation we held over the year.

Investment-grade corporate bonds make up approximately one-half of the Fund's
fixed-income holdings; the other half consists of U.S. Treasuries. The average
maturity of our fixed-income investments is between three and four years. The
shorter maturity and relatively low duration of the Fund's fixed-income
investments has been a benefit to the Fund because they outperformed those of
longer duration the past 12 months.

The equity portion of our portfolio performed well this past year, led by
investments in technology and selected consumer-related issues. Some of the
Fund's largest and best-performing holdings were semiconductor companies,
including Texas Instruments, Xilinx and Altera. In addition, the Fund benefited
from strong performances by semiconductor equipment manufacturers Lam Research,
KLA-Tencor and Applied Materials.

Among the consumer-related stocks in our portfolio, Royal Caribbean Cruise
Lines, Best Buy and Park Place Entertainment turned in strong performances for
the year. Laggards early in the year were Elan and Saks Fifth Avenue. We sold
our positions in both of these companies late in the first quarter 1999 when we
saw the fundamental performance of their businesses begin to degrade.

Initial public offerings (IPO's) also made a positive contribution to the Fund's
performance during the year, although it is unclear whether this market for
IPO's will continue into next year. These companies included Genentech, a
biopharmaceutical manufacturer, Juniper Networks, a telecommunications equipment
company, and Ariba, a leader in business-to-business electronic commerce.

LOOKING AHEAD

As we approach the end of 1999 and the beginning of 2000, we remain cautiously
optimistic about prospects for the U.S. stock markets. We are optimistic because
we believe a strong U.S. economy and improving economic trends internationally
bode well for corporate earnings over the near term. We are cautious, however,
because we continue to see upward pressure on interest rates.

The wild card going forward, of course, is that the turn of the millennium could
bring more volatility to the U.S. stock and bond markets. For this reason, the
Fund will maintain its focus on short maturity assets on the fixed-income side
of the portfolio. For the equity side, we will continue to seek fundamentally
sound companies with excellent revenue and earnings growth prospects for the
future.

1. Past performance does not guarantee future results. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

2. The S&P 500 Index is an unmanaged index, with dividends reinvested, which
consists of the common stocks of 500 publicly traded U.S. companies. It is a
generally recognized indicator used to measure overall performance of the U.S.
stock market. One cannot invest directly in an index.

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 100 Fund ("100"), 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.

100 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 each commenced operations on August 16, 1999.

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"), formerly Berger Associates, Inc., or BBOI
Worldwide LLC ("BBOI").

Effective September 30, 1999, Berger Associates, Inc. transferred its operating
assets and business to Berger. Accordingly, Berger now serves as investment
advisor and administrator to the Funds. The transfer did not result in any
change to the investment objectives or principal investment strategies of the
Funds, or result in any change to the day-to-day management of the Funds'
investments.

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 (9% at September 30, 1999). 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 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 directors/trustees of the Funds.

Annual Report              September 30, 1999                       Berger Funds
                                                                              57

                     NOTES TO FINANCIAL STATEMENTS

- --------------------------------------------------------------------------------
1    ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES - CONTINUED
- --------------------------------------------------------------------------------

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, 100, BG&I and BBAL pursuant to agreements that provide for an
investment advisory fee to be paid to Berger at the following annual rates as a
percentage of average daily net assets: TECH, BNG, BSCG and BSCV -- .90%; 100,
BSEL, BMCG, BMCV and BG&I -- .75%; and BBAL -- .70%. 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 and Company

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 voluntarily waive its advisory fee for TECH; Inv.

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 shareholders of prospectuses and other required
communication and certain other administrative services. BBOI has delegated the
administration of BBIF to Berger.

TECH, BNG, BSEL, BSCG, BSCV, BMCG, BMCV, 100, BG&I and BBAL have each entered
into an administrative services agreement with Berger. The administrative
services agreement provides for an annual fee of .01% of the average daily net
assets of each Fund, computed daily and payable monthly.

Effective October 1, 1999, Berger has agreed to eliminate the 0.01%
administrative services fee charged to the Funds. Berger will continue providing
the same administrative services it currently provides to the Funds at no cost
to the Funds.

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 Investors Fiduciary Trust Company ("IFTC"), 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.
IFTC'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 IFTC 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 periods ended September 30, 1999, the following credits were earned:

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 September 30, 1999, such directors'/trustees' fees and expenses
totaled $334,179 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 September 30, 1999, 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 September 30, 1999, the Funds
held no options or open forward contracts.

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. For the fiscal year ended September 30,
1999, 1%, 48%, 6%, 16%, 19%, 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, 1999, the following
percentages of capital gain distributions were considered long-term capital
gains:

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.
During the periods ended September 30, 1999, the following reclassifications
were made:

                        NOTES TO FINANCIAL STATEMENTS

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. The
Portfolio commenced investment operations with the sale of 448,161 shares of
beneficial interest to the International Equity Fund, formerly known as the
Berger/BIAM International Institutional Fund, in exchange for portfolio assets
with an aggregate value of $4,481,609, which were transferred from the Pooled
Trust of Citizens Bank of New Hampshire ("Citizens NH") to the International
Equity Fund and, in turn, transferred to the Portfolio. Such transaction was a
tax-free exchange. Citizens NH was an affiliate of Bank of Ireland Asset
Management (U.S.) Limited ("BIAM"), which was the investment sub-advisor to the
Pooled Trust and is the investment sub-advisor to the Portfolio. Citizens NH
sold their 23.5% interest on September 4, 1998. 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 BIAM. Berger LLC ("Berger"), formerly Berger
Associates, Inc., and BIAM each own 50% of BBOI. Effective September 30, 1999,
Berger Associates, Inc. transferred its operating assets and business to Berger.
The transfer did not result in any change to the investment objective or
principal investment strategies of the Portfolio, or result in any change to the
day-to-day management of the Portfolio's investments.

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.

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

                     BERGER/BIAM INTERNATIONAL PORTFOLIO

1    ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

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 manage ment 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 has agreed
to waive its advisory fee to the extent that the Portfolio's normal operating
expenses in any fiscal year (including the investment advisory fee and custodian
fees, but excluding brokerage commissions, interest, taxes and extraordinary
expenses) exceed 1.00% of the Portfolio's average daily net assets for that
fiscal year. 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
Investors Fiduciary Trust Company ("IFTC"), 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 Berger Funds
(which consists of Berger Information Technology Fund, Berger New Generation
Fund, Berger Select Fund, Berger Small Company Growth Fund, Berger Small Cap
Value Fund, Berger Mid Cap Growth Fund, Berger Mid Cap Value Fund, Berger 100
Fund, Berger Growth & Income Fund and Berger Balanced Fund) (collectively, the
"Funds"). IFTC'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 IFTC as custodian and by credits
received from directed brokerage transactions.

Certain officers and trustees of the Trust are officers and directors of Berger,
BBOI or BIAM. Trustees who are not affiliated with Berger, BBOI or BIAM are
compensated for their services according to a fee schedule, allocated among the
Berger Funds and the Portfolio, 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, 1999, totaled $22,213.

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.

</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 gains or losses on these
securities are included in Net Realized Gain (Loss) on Investments and Foreign
Currency Transactions 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.

4    LINE OF CREDIT

The Portfolio, along with certain of the 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 on borrowings, if any, is charged to
the specific Fund or Portfolio that executes the borrowing at the Federal Funds
Rate plus 50 basis points. 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, 1999, the Portfolio had no borrowings
outstanding on the line of credit.

                      REPORT OF INDEPENDENT ACCOUNTANTS

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

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

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/supplemental data,
as applicable, present fairly, in all material respects, the financial position
of 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/BIAM International Portfolio (the sole portfolio
comprising Berger/BIAM Worldwide Portfolios Trust), and Berger/BIAM
International Fund (one of the funds constituting Berger/BIAM Worldwide Funds
Trust) (collectively, the "Funds") at September 30, 1999, the results of each of
their operations for the periods indicated, the changes in each of their net
assets for each of the periods indicated and the financial highlights or
ratios/supplemental data for each of the periods indicated, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights or ratios/supplemental 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 generally accepted auditing standards, 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, 1999 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above. 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.

PERFORMANCE

   The International Equity Fund (the "Fund") had a total return of 30.36%(1)
for the year ended September 30, 1999 compared to 31.32% for the MSCI EAFE
Index.(2)

  Global equity markets began the fiscal year last October with strong
performances, prompted primarily by interest rate reductions in both the U.S.
and Europe. In January, European markets benefited from the introduction of the
new single currency, the euro, and Japanese markets enjoyed positive investor
sentiment as a result of overseas buying. Markets in the rest of the Pacific
region turned in mixed results largely due to a pick-up in sentiment towards
Japan and the phenomenon of western multinationals seeking stakes in Asian
companies.

  By the second calendar quarter 1999, the new euro currency received negative
press following a steady decline against the U.S. dollar and other major
currencies. We believe the euro is acting as a catalyst for change, however, and
increasing competition across Europe.

  We remained extremely cautious about investing in Southeast Asia this year,
even though the acute financial crisis appears to be over. Although Japanese
figures have been strong, we believe Japan is a stock-picker's market because
not all companies will deliver on the promises they are making to investors. As
a result, we added to our Japanese holdings over the year on a stock-by-stock
basis.

YEAR IN REVIEW

   Two groups of stocks led our portfolio higher this fiscal year: those in the
Growth in Telecommunications theme and Japanese-quoted stocks, particularly
those in our Technological Innovation theme.

  The most notable performers among Growth in Telecommunications stocks for the
year were German-quoted Mannesmann and NTT Mobile Communications Network. NTT
Mobile Communications Network was among our strongest contributors during the
past six months. The company is Japan's dominant cellular phone operator and its
stock rose on the belief that the company will benefit from growing demand for
data transmission services through cellular phones. Two holdings--UK-quoted
Vodafone AirTouch Group and Telecom Italia--were involved in the merger and
acquisition activity that engulfed global telecommunication companies earlier in
the year.

  Japanese-quoted stocks began their comeback early in our fiscal year and have
been our leading performers since March 31. Electronics exporters, in
particular, did well on the

back of buoyant global demand for PCs, copiers, printers, mobile phones and
their related components. Leading the way was Murata Manufacturing, which raised
its net profit forecast by 25% for the coming year and announced plans to
increase its production capacity in response to demand for the electronic
components used in cellular phones. Semiconductor manufacturer Rohm also
increased its profit projections on the heels of higher-than-expected sales of
circuits for mobile communications equipment.

  The primary reason we slightly lagged our benchmark for the year was the
performance of stocks in the Positive Banking Environment theme. After
strengthening early in the year, these stocks faltered the second half, largely
due to a negative interest rate environment. (Both the U.S. Federal Reserve
Board and the Bank of England raised interest rates in response to upward
pressure on inflation rates attributable to a stronger global economy.) One
example of the impact of interest-rate concerns was the response to National
Australia Bank. Even though the bank released results that were greeted
positively by analysts, its stock price fell.

LOOKING AHEAD

   The pace of global economic change continues to accelerate and all of the
world's major economic regions are expanding. Europe is benefiting from the
combined effects of a monetary policy biased towards stimulating growth, a
competitive currency and general global recovery. The latest economic data in
the UK also reveal a significant acceleration in growth. Surveys show that
business confidence is increasing while unemployment is falling. Economic
activity in the Pacific Region continues its strong rebound.

  As global growth gathers pace, we have been paying close attention to
developments in Japan. We are gradually beginning to be convinced that this
year's economic recovery may be sustainable. But, while many Japanese companies
are making very encouraging statements about restructuring, there is significant
execution risk for investors who are looking to take advantage of these changes.
There is a danger that Japanese companies may avoid making painful decisions
simply because their stock prices have recovered from their lows. Having said
that, we believe that there is real and substantial restructuring underway in
Japan and we are attempting to identify companies that are in the forefront of
this change.

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1999

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

   The International Equity Fund (the "Fund"), formerly known as the Berger/BIAM
International Institutional Fund prior to June 20, 1997, is a series of the
Berger/BIAM Worldwide Funds Trust (the "Trust"), a Delaware business trust,
organized on May 31, 1996. The Trust is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The Trust
is authorized to issue an unlimited number of shares of beneficial interest in
series or portfolios. Currently, the series comprising the Fund, Berger/BIAM
International Fund and Berger/BIAM International CORE Fund, are the only series
established under the Trust, although others may be added in the future. The
Trust is also authorized to establish multiple classes of shares representing
differing interests in an existing or new series.

   The investment objective of the Fund is long-term capital appreciation. The
Fund will invest all of its investable assets in the Berger/BIAM International
Portfolio (the "Portfolio"), a series of Berger/BIAM Worldwide Portfolios Trust.
The value of such investment reflects the Fund's proportionate interest in the
net assets of the Portfolio (4% at September 30, 1999). The Portfolio is an
open-end management investment company and has the same investment objective and
policies as the Fund. The performance of the Fund 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 the Fund's financial statements.
All costs in organizing the Trust were borne by BBOI Worldwide LLC, the
investment advisor of the Portfolio (the "Advisor"). The Advisor has delegated
the daily investment management of the Portfolio to Bank of Ireland Asset
Management (U.S.) Limited ("BIAM" or the "Sub-Advisor"), which owns 50% of the
Advisor. Berger LLC ("Berger"), formerly Berger Associates, Inc., owns the
remaining 50% of the Advisor.

   Effective September 30, 1999, Berger Associates, Inc. transferred its
operating assets and business to Berger. The transfer did not change the
investment objective or principal investment strategies of the Fund, or result
in any change to the day-to-day management of the Fund's investments.

SIGNIFICANT ACCOUNTING POLICIES

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

                                       8

<PAGE>
                                                       INTERNATIONAL EQUITY FUND

INVESTMENT VALUATION

   Since the Fund will invest all of its investable assets in the Portfolio, the
value of the Fund's invested 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 accompany these
Financial Statements for the Fund.

CALCULATION OF NET ASSET VALUE

   The per share calculation of net asset value is determined by dividing the
total value of the Fund's assets, less liabilities, by the total number of
shares outstanding.

INCOME AND EXPENSES

   As an investor in the Portfolio, the Fund 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 the
Fund relative to the other investors in the Portfolio. Expenses directly
attributable to the Fund are charged against the operations of the Fund.

FEDERAL INCOME TAXES

   Each series of the Trust is treated as a separate entity for federal income
tax purposes. The Fund's policy is to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to shareholders. Therefore, no income tax
provision is required.

FEDERAL INCOME TAX STATUS

   Dividends paid by the Fund 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, 1999, 100% of the capital gain
distributions of the Fund were long-term capital gains.

   The Fund distributes net realized capital gains, if any, to its 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 treatments 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 are reclassified to paid-in-capital.

   At September 30, 1999, the Fund had a capital loss carryover in the amount of
$315,964, expiring on September 30, 2007, which may be used to offset future
realized capital gains for federal income tax purposes.

   During the year ended September 30, 1999, the Fund paid $21,059 of foreign
taxes on $541,518 of foreign source income. The Fund will make the foreign tax
credit election to pass these taxes through to shareholders.

   For the year ended September 30, 1999, the Fund incurred and elected to defer
post-October 31 net capital and/or currency losses totaling $169,207 to the year
ended September 30, 2000.

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 could differ from those estimates.

2. AGREEMENTS

   Under an Administrative Services Agreement with the Fund, the Advisor serves
as the administrator of the Fund. Pursuant to such Agreement, the Fund is
obligated to pay the Advisor a fee at an annual rate equal to the lesser of
0.10% of its average daily net assets or the Advisor's annual cost to provide or
procure such services plus 0.01% of the Fund's average daily net assets. Under
the Agreement, the Advisor is responsible, at its own expense, for providing or
procuring all administrative services reasonably necessary for the operation of
the Fund, including recordkeeping and pricing services, custodian services,
transfer agency and dividend disbursing services, tax and audit services,
insurance, legal services, printing and mailing to shareholders of prospectuses
and other required communications and certain other administrative services. The
Advisor has delegated the administration of the Fund to Berger. For such
services, the Advisor pays Berger a sub-administration fee equal to 0.25% of the
Fund's average daily net assets. Berger has voluntarily waived such
sub-administration fee from the Commencement of Investment Operations through
September 30, 1999.

   Investors Fiduciary Trust Company ("IFTC") has been appointed to provide
recordkeeping and pricing services to the Fund, including calculating the net
asset value of

the Fund, and to perform certain accounting and recordkeeping functions. In
addition, IFTC has been appointed to serve as the Fund's custodian, transfer
agent and dividend disbursing agent. The cost of such services are covered under
the Administrative Services Agreement with the Advisor, as mentioned above.

   Certain officers and trustees of the Trust are officers and directors of
Berger, the Advisor or BIAM. Trustees who are not affiliated with Berger, the
Advisor or BIAM are compensated for their services according to a fee schedule,
allocated among the Berger Funds (which consists of Berger Information
Technology Fund, Berger New Generation Fund, Berger Select Fund, Berger Small
Company Growth Fund, Berger Small Cap Value Fund, Berger Mid Cap Growth Fund,
Berger Mid Cap Value Fund, Berger 100 Fund, Berger Growth and Income Fund, and
Berger Balanced Fund) and the Portfolio, which includes an annual fee component
and a per meeting component. Such fees are allocated directly to the Portfolio
and, therefore, indirectly to the Fund.

                    REPORT OF INDEPENDENT ACCOUNTANTS
                               EQUITY FUND

To the Board of Trustees and Shareholders of
 International Equity Fund

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
International Equity Fund (one of the funds constituting Berger/BIAM Worldwide
Funds Trust, hereafter referred to as the "Fund") at September 30, 1999, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the two years in the period then ended and for the period
October 11, 1996 (commencement of investment operations) through September 30,
1997, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's 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 generally accepted auditing standards 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 provide a reasonable basis for the opinion expressed
above.

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1999

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. The
Portfolio commenced investment operations with the sale of 448,161 shares of
beneficial interest to the International Equity Fund, formerly known as the
Berger/BIAM International Institutional Fund, in exchange for portfolio assets
with an aggregate value of $4,481,609, which were transferred from the Pooled
Trust of Citizens Bank of New Hampshire ("Citizens NH") to the International
Equity Fund and, in turn, transferred to the Portfolio. Such transaction was a
tax-free exchange. Citizens NH was an affiliate of Bank of Ireland Asset
Management (U.S.) Limited ("BIAM"), which was the investment sub-advisor to the
Pooled Trust and is the investment sub-advisor to the Portfolio. Citizens NH
sold their 23.5% interest on September 4, 1998. 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 BIAM. Berger LLC ("Berger"), formerly Berger
Associates, Inc., and BIAM each own 50% of BBOI. Effective September 30, 1999,
Berger Associates, Inc. transferred its operating assets and business to Berger.
The transfer did not result in any change to the investment objective or
principal investment strategies of the Portfolio, or result in any change to the
day-to-day management of the Portfolio's investments.

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.

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 has agreed
to waive its advisory fee to the extent that the Portfolio's normal operating
expenses in any fiscal year (including the investment advisory fee and custodian
fees, but excluding brokerage commissions, interest, taxes and extraordinary
expenses) exceed 1.00% of the Portfolio's average daily net assets for that
fiscal year. 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
Investors Fiduciary Trust Company ("IFTC"), 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 Berger Funds
(which consists of Berger Information Technology Fund, Berger New Generation
Fund, Berger Select Fund, Berger Small Company Growth Fund, Berger Small Cap
Value Fund, Berger Mid Cap Growth Fund, Berger Mid Cap Value Fund, Berger 100
Fund, Berger Growth & Income Fund and Berger Balanced Fund) (collectively, the
"Funds"). IFTC'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 IFTC as custodian and by credits
received from directed brokerage transactions.

   Certain officers and trustees of the Trust are officers and directors of
Berger, BBOI or BIAM. Trustees who are not affiliated with Berger, BBOI or BIAM
are compensated for their services according to a fee schedule, allocated among
the Berger Funds and the Portfolio, 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, 1999, totaled $22,213.

   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.

</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 gains or losses on these securities are included in Net Realized Gain
(Loss) on Investments and Foreign Currency Transactions 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

                                       26

<PAGE>
                                             BERGER/BIAM INTERNATIONAL PORTFOLIO
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.

4. LINE OF CREDIT

   The Portfolio, along with certain of the 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 on borrowings, if any, is charged to
the specific Fund or Portfolio that executes the borrowing at the Federal Funds
Rate plus 50 basis points. 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, 1999, the Portfolio had no borrowings
outstanding on the line of credit.

                    REPORT OF INDEPENDENT ACCOUNTANTS
                         INTERNATIONAL PORTFOLIO

To the Board of Trustees and Investors of
 Berger/BIAM Worldwide Portfolios Trust

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the ratios/supplemental data present fairly, in all
material respects, the financial position of Berger/BIAM International Portfolio
(the sole portfolio comprising Berger/BIAM Worldwide Portfolios Trust, hereafter
referred to as the "Portfolio") at September 30, 1999, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the ratios/ supplemental data for
each of the two years in the period then ended and for the period October 11,
1996 (commencement of investment operations) through September 30, 1997, in
conformity with generally accepted accounting principles. These financial
statements and ratios/supplemental data (hereafter referred to as "financial
statements") are the responsibility of the Portfolio's 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 generally accepted auditing standards 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, 1999 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

PERFORMANCE

   The Berger/BIAM International CORE Fund (the "Fund") had a total return of
30.45%(1) for the year ended September 30, 1999 compared to 31.32% for the MSCI
EAFE Index.(2)

  Global equity markets began the fiscal year last October with strong
performances, prompted primarily by interest rate reductions in both the U.S.
and Europe. In January, European markets benefited from the introduction of the
new single currency, the euro, and Japanese markets enjoyed positive investor
sentiment as a result of overseas buying. Markets in the rest of the Pacific
region turned in mixed results largely due to a pick-up in sentiment towards
Japan and the phenomenon of western multinationals seeking stakes in Asian
companies.

  By the second calendar quarter 1999, the new euro currency received negative
press following a steady decline against the U.S. dollar and other major
currencies. We believe the euro is acting as a catalyst for change, however, and
increasing competition across Europe.

  We remained extremely cautious about investing in Southeast Asia this year,
even though the acute financial crisis appears to be over. Although Japanese
figures have been strong, we believe Japan is a stock-picker's market because
not all companies will deliver on the promises they are making to investors. As
a result, we added to our Japanese holdings over the year on a stock-by-stock
basis.

YEAR IN REVIEW

   Two groups of stocks led our portfolio higher this fiscal year: those in the
Growth in Telecommunications theme and Japanese-quoted stocks, particularly
those in our Technological Innovation theme.

  The most notable performers among Growth in Telecommunications stocks for the
year were German-quoted Mannesmann and NTT Mobile Communications Network. NTT
Mobile Communications Network was among our strongest contributors during the
past six months. The company is Japan's dominant cellular phone operator and its
stock rose on the belief that the company will benefit from growing demand for
data transmission services through cellular phones. Two holdings --UK-quoted
Vodafone AirTouch Group and Telecom Italia --were involved in the merger and
acquisition activity that engulfed global telecommunication companies earlier in
the year.

  Japanese-quoted stocks began their comeback early in our fiscal year and have
been our leading performers since March 31. Electronics exporters, in
particular, did well on the

                                       2

                                             BERGER/BIAM INTERNATIONAL CORE FUND

back of buoyant global demand for PCs, copiers, printers, mobile phones and
their related components. Leading the way was Murata Manufacturing, which raised
its net profit forecast by 25% for the coming year and announced plans to
increase its production capacity in response to demand for the electronic
components used in cellular phones. Semiconductor manufacturer Rohm also
increased its profit projections on the heels of higher-than-expected sales of
circuits for mobile communications equipment.

  The primary reason we slightly lagged our benchmark for the year was the
performance of stocks in the Positive Banking Environment theme. After
strengthening early in the year, these stocks faltered the second half, largely
due to a negative interest rate environment. (Both the U.S. Federal Reserve
Board and the Bank of England raised interest rates in response to upward
pressure on inflation rates attributable to a stronger global economy.) One
example of the impact of interest-rate concerns was the response to National
Australia Bank. Even though the bank released results that were greeted
positively by analysts, its stock price fell.

LOOKING AHEAD

   The pace of global economic change continues to accelerate and all of the
world's major economic regions are expanding. Europe is benefiting from the
combined effects of a monetary policy biased towards stimulating growth, a
competitive currency and general global recovery. The latest economic data in
the UK also reveal a significant acceleration in growth. Surveys show that
business confidence is increasing while unemployment is falling. Economic
activity in the Pacific Region continues its strong rebound.

  As global growth gathers pace, we have been paying close attention to
developments in Japan. We are gradually beginning to be convinced that this
year's economic recovery may be sustainable. But, while many Japanese companies
are making very encouraging statements about restructuring, there is significant
execution risk for investors who are looking to take advantage of these changes.
There is a danger that Japanese companies may avoid making painful decisions
simply because their stock prices have recovered from their lows. Having said
that, we believe that there is real and substantial restructuring underway in
Japan and we are attempting to identify companies that are in the forefront of
this change.

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1999

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

   The Berger/BIAM International CORE Fund (the "Fund") is a series of the
Berger/ BIAM Worldwide Funds Trust (the "Trust"), a Delaware business trust,
organized on May 31, 1996. The Trust is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The Trust
is authorized to issue an unlimited number of shares of beneficial interest in
series or portfolios. Currently, the series comprising the Fund, Berger/BIAM
International Fund and International Equity Fund, are the only series
established under the Trust, although others may be added in the future. The
Trust is also authorized to establish multiple classes of shares representing
differing interests in an existing or new series.

   The investment objective of the Fund is long-term capital appreciation. The
Fund will invest all of its investable assets in the Berger/BIAM International
Portfolio (the "Portfolio"), a series of Berger/BIAM Worldwide Portfolios Trust.
The value of such investment reflects the Fund's proportionate interest in the
net assets of the Portfolio (87% at September 30, 1999). The Portfolio is an
open-end management investment company and has the same investment objective and
policies as the Fund. The performance of the Fund 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 the Fund's financial statements.
All costs in organizing the Trust were borne by BBOI Worldwide LLC, the advisor
of the Portfolio (the "Advisor"). The Advisor has delegated the daily investment
management of the Portfolio to Bank of Ireland Asset Management (U.S.) Limited
("BIAM" or the "Sub-Advisor"), which owns 50% of the Advisor. Berger LLC
("Berger"), formerly Berger Associates, Inc., owns the remaining 50% of the
Advisor.

   Effective September 30, 1999, Berger Associates, Inc. transferred its
operating assets and business to Berger. The transfer did not change the
investment objective or principal investment strategies of the Fund, or result
in any change to the day-to-day management of the Fund's investments.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATION

   Since the Fund will invest all of its investable assets in the Portfolio, the
value of the Fund's invested assets will be equal to the value of its beneficial
interest in the

                                       8

<PAGE>
                                             BERGER/BIAM INTERNATIONAL CORE FUND
Portfolio. Valuation of securities by the Portfolio is discussed in Note 1 of
the Portfolio's Notes to Financial Statements which accompany these Financial
Statements for the Fund.

CALCULATION OF NET ASSET VALUE

   The per share calculation of net asset value is determined by dividing the
total value of the Fund's assets, less liabilities, by the total number of
shares outstanding.

INCOME AND EXPENSES

   As an investor in the Portfolio, the Fund 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 the
Fund relative to the other investors in the Portfolio. Expenses directly
attributable to the Fund are charged against the operations of the Fund.

FEDERAL INCOME TAXES

   Each series of the Trust is treated as a separate entity for federal income
tax purposes. The Fund's policy is to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to shareholders. Therefore, no income tax
provision is required.

FEDERAL INCOME TAX STATUS

   Dividends paid by the Fund 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 Fund distributes net realized capital gains, if any, to its 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 treatments 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 are reclassified to paid-in-capital.

   During the year ended September 30, 1999, the following reclassifications
were made:

Paid-in-Capital                      $   159,926

BERGER/BIAM INTERNATIONAL CORE FUND

   At September 30, 1999, the Fund had the following capital loss carryovers
which may be used to offset future realized capital gains for federal income tax
purposes:

  Total capital loss carryovers      $6,749,679
                                     ==========
</TABLE>

   During the year ended September 30, 1999, the Fund paid $418,229 of foreign
taxes on $10,916,538 of foreign source income. The Fund will make the foreign
tax credit election to pass these taxes through to shareholders.

   For the year ended September 30, 1999, the Fund incurred and elected to defer
post-October 31 net capital and/or currency losses totaling $2,362,430, to the
year ended September 30, 2000.

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 could differ from those estimates.

2. AGREEMENTS

   Under an Administrative Services Agreement with the Fund, the Advisor serves
as the administrator of the Fund. Pursuant to such Agreement, the Fund pays the
Advisor a fee at an annual rate equal to the lesser of 0.10% of its average
daily net assets or the Advisor's annual cost to provide or procure such
services plus 0.01% of the Fund's average daily net assets. Under the Agreement,
the Advisor is responsible, at its own expense, for providing or procuring all
administrative services reasonably necessary for the operation of the Fund,
including recordkeeping and pricing services, custodian services, transfer
agency and dividend disbursing services, tax and audit services, insurance,
legal services, printing and mailing to shareholders of prospectuses and other
required communications and certain other administrative services. The Advisor
has delegated the administration of the Fund to Berger. For such services, the
Advisor pays Berger a sub-administration fee equal to 0.25% of the Fund's
average daily net assets. Berger has voluntarily waived such sub-administration
fee from the Commencement of Investment Operations through September 30, 1999.

   Investors Fiduciary Trust Company ("IFTC") has been appointed to provide
recordkeeping and pricing services to the Fund, including calculating the net
asset value of the Fund, and to perform certain accounting and recordkeeping
functions. In addition,

                                       10

<PAGE>
                                             BERGER/BIAM INTERNATIONAL CORE FUND
IFTC has been appointed to serve as the Fund's custodian, transfer agent and
dividend disbursing agent. The cost of such services are covered under the
Administrative Services Agreement with the Advisor, as mentioned above.

   Certain officers and trustees of the Trust are officers and directors of
Berger, the Advisor or BIAM. Trustees who are not affiliated with Berger, the
Advisor or BIAM are compensated for their services according to a fee schedule,
allocated among the Berger Funds (which consists of Berger Information
Technology Fund, Berger New Generation Fund, Berger Select Fund, Berger Small
Company Growth Fund, Berger Small Cap Value Fund, Berger Mid Cap Growth Fund,
Berger Mid Cap Value Fund, Berger 100 Fund, Berger Growth and Income Fund, and
Berger Balanced Fund) and the Portfolio, which includes an annual fee component
and a per meeting component. Such fees are allocated directly to the Portfolio
and, therefore, indirectly to the Fund.

                    REPORT OF INDEPENDENT ACCOUNTANTS
                   INTERNATIONAL CORE FUND

To the Board of Trustees and Shareholders of
 Berger/BIAM International CORE Fund

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Berger/BIAM International CORE Fund (one of the funds constituting Berger/BIAM
Worldwide Funds Trust, hereafter referred to as the "Fund") at September 30,
1999, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended and the financial
highlights for each of the two years in the period then ended and for the period
October 11, 1996 (commencement of investment operations) through September 30,
1997, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's 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 generally accepted auditing standards 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 provide a reasonable basis for the opinion expressed
above.

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1999

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. The
Portfolio commenced investment operations with the sale of 448,161 shares of
beneficial interest to the International Equity Fund, formerly known as the
Berger/BIAM International Institutional Fund, in exchange for portfolio assets
with an aggregate value of $4,481,609, which were transferred from the Pooled
Trust of Citizens Bank of New Hampshire ("Citizens NH") to the International
Equity Fund and, in turn, transferred to the Portfolio. Such transaction was a
tax-free exchange. Citizens NH was an affiliate of Bank of Ireland Asset
Management (U.S.) Limited ("BIAM"), which was the investment sub-advisor to the
Pooled Trust and is the investment sub-advisor to the Portfolio. Citizens NH
sold their 23.5% interest on September 4, 1998. 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 BIAM. Berger LLC ("Berger"), formerly Berger
Associates, Inc., and BIAM each own 50% of BBOI. Effective September 30, 1999,
Berger Associates, Inc. transferred its operating assets and business to Berger.
The transfer did not result in any change to the investment objective or
principal investment strategies of the Portfolio, or result in any change to the
day-to-day management of the Portfolio's investments.

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

                                       23

<PAGE>
BERGER/BIAM INTERNATIONAL PORTFOLIO
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.

                                             BERGER/BIAM INTERNATIONAL PORTFOLIO

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 has agreed
to waive its advisory fee to the extent that the Portfolio's normal operating
expenses in any fiscal year (including the investment advisory fee and custodian
fees, but excluding brokerage commissions, interest, taxes and extraordinary
expenses) exceed 1.00% of the Portfolio's average daily net assets for that
fiscal year. 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
Investors Fiduciary Trust Company ("IFTC"), 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 Berger Funds
(which consists of Berger Information Technology Fund, Berger New Generation
Fund, Berger Select Fund, Berger Small Company Growth Fund, Berger Small Cap
Value Fund, Berger Mid Cap Growth Fund, Berger Mid Cap Value Fund, Berger 100
Fund, Berger Growth & Income Fund and Berger Balanced Fund) (collectively, the
"Funds"). IFTC'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 IFTC as custodian and by credits
received from directed brokerage transactions.

   Certain officers and trustees of the Trust are officers and directors of
Berger, BBOI or BIAM. Trustees who are not affiliated with Berger, BBOI or BIAM
are compensated for their services according to a fee schedule, allocated among
the Berger Funds and the Portfolio, 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, 1999, totaled $22,213.

   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.

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.

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

                                             BERGER/BIAM INTERNATIONAL PORTFOLIO
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.

4. LINE OF CREDIT

   The Portfolio, along with certain of the 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 on borrowings, if any, is charged to
the specific Fund or Portfolio that executes the borrowing at the Federal Funds
Rate plus 50 basis points. 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, 1999, the Portfolio had no borrowings
outstanding on the line of credit.

                    REPORT OF INDEPENDENT ACCOUNTANTS
                   INTERNATIONAL PORTFOLIO

To the Board of Trustees and Investors of
 Berger/BIAM Worldwide Portfolios Trust

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the ratios/supplemental data present fairly, in all
material respects, the financial position of Berger/BIAM International Portfolio
(the sole portfolio comprising Berger/BIAM Worldwide Portfolios Trust, hereafter
referred to as the "Portfolio") at September 30, 1999, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the ratios/supplemental data for each
of the two years in the period then ended and for the period October 11, 1996
(commencement of investment operations) through September 30, 1997, in
conformity with generally accepted accounting principles. These financial
statements and ratios/supplemental data (hereafter referred to as "financial
statements") are the responsibility of the Portfolio's 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 generally accepted auditing standards 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, 1999 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.
