Dear 
Fellow 
Shareholders 

                 A Letter from the President

                     This past fiscal year 
                       was the most active and exciting 
                       year in The Berger Funds history.

We concentrated on several clear goals * attracting more world class portfolio
managers * expanding our innovative, fundamentally sound line-up of products *
providing strong, consistent performance across all funds * and enhancing our
customer services and support.

I am pleased to report that we have made very significant progress on all
fronts. Here are a few of the highlights:

Our Small Company Growth and New Generation Funds both rebounded sharply from a
small cap bear market earlier this year. The performance of both Funds has been
recognized recently by major national publications/1,2/. The Funds are managed
by Bill Keithler who was again listed among the nation's top 100 managers in
Barron's recent annual issue that highlights the country's best mutual fund
managers.

We expanded our line-up of fund offerings this year by adding the Berger Small
Cap Value Fund, the Berger/BIAM International Fund and the Berger Balanced Fund.
By year-end we plan on offering you two more funds, a Select Fund and a Mid Cap
Growth Fund. In all, we will have dramatically increased the range of Berger
investment opportunities available to you. This expansion is driven by what
we've heard loud and clear from you, our customers, in extensive research we
conducted this year: give us more choice, more stock investment opportunities
and excellent service. We intend to do just that.

The Small Cap Value Fund, managed by 30-year investment veteran Bob Perkins, had
a terrific year, and also offers a strong long-term track record/1/. Bob
specializes in investing in sharply undervalued small cap companies that he
believes have excellent future prospects./2/

We were delighted to form a joint venture with the Bank of Ireland Asset
Management (U.S.) Limited ("BIAM")/3/, one of the oldest, most respected and
successful managers of international investments in Europe. The partnership
spawned the first of what is planned to be a series of international funds. The
Berger/BIAM International Fund generally focuses on mid to large cap
multinational companies outside the U.S. with strong balance sheets, proven
management and diversified earnings in well-regulated, stable foreign markets.

In February we hired Patrick Adams to take over management of the Berger 100
Fund. Although it had shown gains, the Fund had not performed up to our
expectations. We searched for a proven portfolio manager with a successful track
record in the growth fund area to reinvigorate it. Patrick fit the bill. It took
him several months to reposition the portfolio, and today the Fund is performing
better/1/. Money Magazine recently listed the Fund among its 10-year "winners." 

We also repositioned the Growth and Income Fund under new portfolio managers.
It, too, is performing much better/1/.

We made a major effort to improve and expand our shareholder services. We
completely rewrote our prospectus in plain English to make it shorter and easier
to understand (look for it in your mail in the coming weeks). We redesigned our
information kit, making it easier to use and more helpful. We expanded the
capabilities of our Quick Access toll-free number to provide you with more
services. It has a simplified menu, faster and more personalized access to your
investments, automated ordering of duplicate tax forms and complete instructions
for communicating with us.

This fall we launched our new web site at www.bergerfunds.com. It provides
background information on all our Funds, performance listings, e-mail, access to
your accounts, status reports, purchases, exchanges and much more.

We have remained vigilant about controlling expenses. I'm pleased to report that
we continue to reduce our expenses. Since 1991, we have cut expenses for the
Berger 100 and Growth and Income Funds about 35% and 40%, respectively. Since
1994, expenses for Small Company Growth are down about 18%.

We believe we are in excellent shape as we head into another year. With a little
help from the markets we are looking forward to an outstanding year.

Everyday we are appreciative of the trust you place in us here at Berger. We
will do our absolute best to continue to earn it.

                                            /s/ Jerry Lavin
                                            Jerry Lavin,

              Berger New Generation Fund  [ART WORK APPEARS HERE]

Portfolio Manager's Commentary     William Keithler

Performance 
During the fiscal year ended September 30, 1997, the Berger New Generation Fund
(the "Fund") delivered an annual total return to investors of 31.53%./1/  This
compares to 40.43% for the S&P 500/2/ and 33.19% for the Russell 2000./3/ While
the Fund is not directly comparable to either of these market indexes, it
nevertheless is useful to compare fund performance with widely watched market
indicators.

Over the course of this fiscal year, shareholders experienced both extremes of
performance. The bear market in aggressive growth stocks, which ran from October
1996 through mid-April 1997, caused the Fund to severely underperform the broad
market. During this period, investors preferred to own slower growing, large cap
"index" stocks, such as Procter and Gamble, Gillette and Coca-Cola, and eschewed
owning the more aggressive stocks that are the staples of this Fund. That tide
turned in April, however, when valuations of the narrow group of stocks that
dominated the performance of the S&P 500 and of the emerging growth sector of
the market got too far apart. As the market began to shift away from index/blue
chip stocks to smaller and mid cap stocks, the latter began to significantly
outperform. This outperformance was reflected in Fund performance. In the month
of May 1997 the Fund was up 21.46%,/1/ and in the month of September it also was
up strongly, rising 10.01%./1/

Although we would caution that the performance demonstrated these two months is
unsustainable, we believe that the longer-term outlook is favorable for the
emerging growth stocks in which the Fund invests. The economy continues to perk
along, although not at a rate that puts pressure on interest rates. Inflation
doesn't appear to be a serious threat, although we are keeping an eye on labor
costs. Valuations, while higher than a few months ago, are not in the
stratosphere. Market psychology seems favorably disposed toward growth
companies.

Year in Review 
The largest weighting in the Fund is technology. This sector is fertile ground
for investment candidates for the Fund because of our charter, which is to seek
investments in companies that are attempting to bring products/services to
market that have the potential to change the way business is conducted in their
industries. The Fund has wide-ranging holdings in technology, including
software, semiconductor, semiconductor capital equipment, computer, peripheral
and service companies. Possibly the most dramatic gains for the Fund were
derived from its sizeable holdings in the semiconductor capital equipment
industry. Significant performers included Applied Materials; ASM Lithography
Holding N.V.; LAM Research Corporation; FEI Company; Credence Systems, Corp.;
Integrated Process Equipment Corp.; and CMG Information Services, Inc. Yahoo,
Inc.; Premenos Technology Corp.; CSG Systems International Inc.; Lycos, Inc.;
and America Online, Inc. also had strong stock price gains.

The Fund seeks to benefit from new ways of doing things and these three leaders
in their fields are typical of the companies in which the Fund invests: Discreet
Logic, Inc., is helping usher in the age of digital television; Sandisk
Corporation, is developing technology for digital cameras; and E*Trade Group,
Inc. is pioneering the use of on-line investment trading.

Healthcare is another area in which new developments are constantly occurring.
Some standout performers in this sector included Aurora Biosciences Corp.,
Theragenics Corp., and Qiagen N.V.

Looking Ahead 
Stocks held in this Fund are often extremely volatile. Investors need to
understand that this Fund is aggressive and can experience violent price swings.
For example, the Fund declined some 17% early in the year and subsequently
rebounded to stand at 34.55% year-to-date as of 9/30/97. That's a swing of over
50% in less than six months.

Such performance is, of course, difficult to duplicate. But, as noted earlier,
we believe that the outlook for aggressive growth stocks is favorable and that
should bode well for the performance of the Fund.


 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 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 common stocks of 2000 U.S. companies with market
     capitalization of $172 million to $1.1 billion. It is a generally
     recognized indicator used to measure overall performance of small company
     stocks. One cannot invest directly in an index.

Report of Independent Accountants 

To the Board of Trustees and Shareholders of Berger Investment Portfolio Trust
- --------------------------------------------------------------------------------
In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Berger Small Company Growth Fund,
Berger New Generation Fund and Berger Balanced Fund (constituting Berger
Investment Portfolio Trust, hereafter referred to as the "Trust") at September
30, 1997, the results of each of their operations for each of the periods
indicated, the changes in each of their net assets for each of the periods
indicated and the financial highlights for each of the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Trust'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, 1997 by correspondence with the custodian and the application of
alternative auditing procedures where securities purchased had not been
received, provide a reasonable basis for the opinion expressed above. The
financial statements of Berger Small Company Growth Fund for the period ended
September 30, 1994 were audited by other independent accountants whose report
dated October 28, 1994 expressed an unqualified opinion on those financial
statements.

9  Annual Report September 30, 1997    The Berger Funds
<PAGE>
 
          Berger Small Company Growth Fund     [ARTWORK APPEARS HERE]

Portfolio Manager's Commentary      William Keithler

Performance
During the fiscal year ended September 30, 1997, the Berger Small Company Growth
Fund's (the "Fund") annual total return was 17.68%/1/. This compares to 33.19%
for the Russell 2000/2/. The Russell 2000-Growth index (a more accurate
comparison for the Berger Small Company Growth Fund) was up 23.26% for the 12-
month period ending September 30, 1997.

The past 12 months have been volatile for investors in small company stocks. In
many ways, there have been two markets during this period.

Year in Review 
Although the Fund performed reasonably well in this schizophrenic market, the
volatility (a characteristic that goes with small cap-aggressive growth) was
sometimes difficult and unsettling. As has been noted in prior letters to
shareholders, the Fund has invested extensively in technology stocks throughout
its history. These stocks are often highly volatile, but generally have provided
good long term returns to investors. This fiscal year was no exception. The
Fund's exposure to technology drove performance on both the upside and the
downside. Many technology stocks have been held by the Fund for a long time,
including Kent Electronics Corp., Safeguard Scientifics, Inc., and Cambridge
Technology Partners. The Fund's weighting in semiconductor capital equipment
companies such as Kulicke and Soffa Industries, Inc., Integrated Process
Technology, Inc., ADE Corp. of Massachusetts, and Etec Systems, Inc. gave the
Fund an additional lift. While we took some profits in this sector and modestly
downscaled our weighting, technology remains a significant sector in the Fund.

By far, the most successful single investment for the Fund was the electronic
auctioneer, Onsale Corp. The stock was purchased as an initial public offering
when the market was very poor for such stocks. When these types of stocks came
back into favor, however, Onsale Corp. was much sought after. As of the Fund's
year-end, Onsale Corp.'s price had risen over five-fold. Other solid
contributors to performance were Fairfield Communities, a vacation interval
company; Consolidated Cigar Corp.; and broadcaster Clear Channel Communications,
a long time holding.

Incyte Pharmaceuticals Inc., a leader in the emerging field of human genomic,
led the charge as the healthcare sector of the portfolio made a positive
contribution to Fund performance. Other strong performers included Medic
Computer Systems, Inc., a provider of healthcare information systems; FPA
Medical Management, Inc., a healthcare service company; and Coventry Corp., a
health maintenance organization. Less successful healthcare investments included
Vertex Pharmaceuticals and Rotech Medical, emerging biotechnology firms that
fell victim to proposed cuts in Medicare spending.

Energy services, financial services, and commercial services provided positive
momentum to the Fund. Marine Drilling Co., Sirrom Capital Corp., and Technology
Solutions, all long time holdings of the Fund, were among the leaders in their
respective sectors. 

Looking Ahead 
Small cap stocks are currently in favor with the market and we believe the
outlook for their continued outperformance remains good. We remain focused on
companies we believe have the potential to provide investors with sustained
outperformance over the long term. If we are successful in finding enough of
these companies, Fund shareholders should enjoy the benefits.

We thank you for your continued confidence.

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 Russell 2000 Index is an unmanaged index, with dividends reinvested,
which consists of common stocks of 2000 U.S. companies with market
capitalization of $172 million to $1.1 billion. It is a generally recognized
indicator used to measure overall performance of small company stocks. One
cannot invest directly in an index.

Report of Independent Accountants 

To the Board of Trustees and Shareholders of 
Berger Investment Portfolio Trust
- --------------------------------------------------------------------------------
In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Berger Small Company Growth Fund,
Berger New Generation Fund and Berger Balanced Fund (constituting Berger
Investment Portfolio Trust, hereafter referred to as the "Trust") at September
30, 1997, the results of each of their operations for each of the periods
indicated, the changes in each of their net assets for each of the periods
indicated and the financial highlights for each of the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Trust'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, 1997 by correspondence with the custodian and the application of
alternative auditing procedures where securities purchased had not been
received, provide a reasonable basis for the opinion expressed above. The
financial statements of Berger Small Company Growth Fund for the period ended
September 30, 1994 were audited by other independent accountants whose report
dated October 28, 1994 expressed an unqualified opinion on those financial
statements.

Portfolio Manager's Commentary      Robert H. Perkins

Performance

The Berger Small Cap Value Fund (the "Fund") had a very rewarding year. The Fund
had an annual total return of 48.32%/1/ (investor shares) and 48.66%/1/
(institutional shares) versus 37.67%, 40.43%, and 33.19% for the Dow Jones
Industrial Average/2/, S&P 500/2/, and Russell 2000/3/ indexes, respectively/4/.

Over the last five months of the fiscal year, small company stocks outperformed
large company stocks by a significant margin. This is the first sustained period
of outperformance since 1993, and we believe it will continue due to the wide
disparity in valuations and relative growth rates that still exist. Of equal
importance is the fact that smaller company outperformance has been largely the
result of strong gains in the "growth" segment of the market, with the "value"
segment lagging. This reinforces our belief that the "value" segment remains the
most undervalued area of the market.

With the S&P 500 trading at 23 to 24 times trailing 12-month earnings, there is
little room for error regarding corporate earnings, interest rates, and economic
surprises. The Russell 2000 - the market index most closely resembling the
stocks in which our Fund typically invests - also sells at approximately 24
times trailing earnings. Historically, this index sells at a 25% premium to the
S&P 500 based on earnings. At present, the vast majority of companies in the
Russell 2000 are expected to have earnings growth that is 50% greater than the
S&P 500 -15% versus 10%. In addition, smaller companies generally have less
international exposure, which means less currency risk. These factors reinforce
our belief that, for the near-term, the relative risk in a fully-priced
investment environment is much less in the small cap market.

Year in Review 

While the list of truly undervalued stocks has become shorter, we feel quite
comfortable with our current holdings. We are maintaining a 20% position in the
bank and thrift area. Earnings visibility remains high in this sector and
consolidation continues to make this an attractive area.

Our continuing search for companies that have fallen over 50% in price due to
short-term problems has led us to increase our exposure in the consumer sector.
As we have said in the past, we feel there is much less downside risk in stocks
that are down over 50%, have strong balance sheets, and exhibit what we believe
to be only temporary problems. One such stock is a company called Just for Feet,
Inc. This shoe retailer was trading in the mid-30s last year. The company has
experienced short-term earnings problems as a result of two recent acquisitions.
Management believes it will take a few quarters to implement better internal
controls while its superstore concept, which is posting positive same-store
sales comparisons, remains intact.

Another company in the consumer area that has fallen out of favor is West
Marine, Inc., which dominates the boating supply industry. It, too, has
experienced temporary earnings declines as a result of a major acquisition.
Margins have already begun to improve, however, and the company is expected to
return to 20%+ growth in 1998.

Looking Ahead 

Going forward, we find it more important than ever to stress the risk side of
the Fund's risk/reward equation. As of year-end, we had over 14% of Fund assets
in cash and cash equivalents. This largely resulted from our inability to find
many "true" values in the market. However, this cash position gives us the
ability to capitalize on values created by general market corrections or
weaknesses in specific companies due to short-term correctable problems.

We thank you for your investment in the Berger Small Cap Value Fund.

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. Performance data for the
Investor Shares include periods prior to the adoption of class designations on
February 14, 1997, and therefore do not reflect the 0.25% per year 12b-1 fee
applicable to the Investor Shares. 
2. Dow Jones Industrial Average and the S&P 500 are unmanaged indexes, with
dividends reinvested. One cannot invest directly in an index.
3. The Russell 2000 Index is an unmanaged index, with dividends
reinvested, which consists of common stocks of 2000 U.S. companies with market
capitalizations of $172 million to $1.1 billion. It is a generally recognized
indicator used to measure overall performance of small company stocks. One
cannot invest directly in an index. 
4. For the nine month period covered by this Fund's annual report, the Fund's
total return was 29.23% (investor shares, first offered February 14, 1997) and
35.50% (institutional shares). For the same period the return for the Dow Jones
Industrial Average, S&P 500 and Russell 2000 were 24.91%, 29.61% and 26.60%
respectively.

you sell shares. Performance data for the Investor Shares include periods prior

Report of Independent Accountants

To the Board of Trustees and Shareholders of Berger Omni Investment 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 financial highlights present fairly, in all
material respects, the financial position of Berger Small Cap Value Fund
(constituting Berger Omni Investment Trust, formerly known as The Omni
Investment Fund, hereafter referred to as the "Trust") at September 30, 1997,
the results of its operations, the changes in its net assets and the financial
highlights for the period from January 1, 1997 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 Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit 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 audit, which included confirmation of securities at
September 30, 1997 by correspondence with the custodian and the application of
alternative auditing procedures where securities purchased had not been
received, provides a reasonable basis for the opinion expressed above. The
financial statements of The Omni Investment Fund for the year ended December 31,
1996 were audited by other independent accountants whose report dated January
24, 1997 expressed an unqualified opinion on those financial statements.

Portfolio Manager's Commentary      Patrick S. Adams

Performance
As stated in Berger One Hundred Fund's (the "Fund") March 31, 1997 report to
shareholders, our goal is to return our flagship Fund to its proper place as a
performance leader among its peers. We have taken giant strides toward achieving
this goal over the past six months, even though it is not reflected in the
Fund's annual total return of 26.50%/1/ for the year ended September 30, 1997.
We still trailed the Standard & Poor's (S&P) 500/2/ annual total return, which
was 40.43% for the same period.

The Fund's poor showing early in the year is the key reason why we lagged the
index on an annualized basis. But the Fund's performance began to improve in
April. For the period July 1 - September 30, 1997, the Fund's total return of
13.50%/1/ exceeded that of the S&P 500 by 6.01%. We feel we're back on track
with a portfolio striving for excellent near-term and long-term performance.

Year in Review 
In February we began to make numerous changes in the Fund that we believed would
improve quality and maintain the long-term growth rate target. We broadened the
portfolio, increasing the number of stocks from 53 in early February to 90 on
March 31 (86 at year-end). We shifted assets away from energy services and into
consumer products because we saw strong potential and a number of attractively
valued stocks in the consumer sector. We maintained a high percentage of Fund
assets in technology but added new stocks to the portfolio and reduced positions
in others.

Our restructuring was complete in April and our efforts began to pay off for
shareholders in the third calendar quarter 1997, when the Fund outperformed
broad market indexes. On the basis of this strong performance, we elected to
take some profits during the quarter. Although we sold some technology holdings
to take profits, we slightly increased the percentage of Fund assets invested in
this sector from 24.3% at the end of the second quarter to 24.8% as of September
30. We remain overweighted in technology and healthcare and are selectively
adding to our capital goods holdings. We reduced consumer holdings to
approximately 10% of Fund assets as of year-end. At year-end, stocks held by the
Fund were trading at about the same multiple of earnings per share as the S&P
500, but had long-term growth rates nearly twice that of the index. The
fundamentals of companies owned by the Fund are strong. We had established core
positions in many excellent companies (Motorola, GAP Stores, Tommy Hilfiger, and
Nordstrom, among others) and were trading around those stocks. For example, we
purchased more Cisco Systems on a price decline and sold some Cadence Design
Systems, then our largest position, on a price run up. We identified two new
stocks to add to the portfolio - Household International, parent of Coldwell
Banker, and Safeway. We see excellent upside potential in both stocks based on
our analysis. We still like the technology sector for the long-term and are
actively seeking quality stocks to add to the portfolio, perhaps rebuilding
technology, once again, to an overweighted position.

Looking Ahead 
The key risk to the portfolio in the future, in our opinion, is a too-robust
economy that the Federal Reserve Board could decide to hold down with interest
rate increases. We do not see the portfolio adversely impacted by earnings
announcements or currency fluctuations.

Going forward, your Fund's performance should continue to strengthen as we
continue to adhere closely to the philosophy that has guided this Fund since
1974 - seek high quality, predictable growth companies at attractive prices.

We thank you for your investment in the Berger One Hundred Fund, and for your
patience as we restructured it.

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 is an unmanaged index, with dividends reinvested, which consists
of the common stocks of 500 publicly traded U.S. companies. One cannot invest
directly in an index.

Report of Independent Accountants 

To the Board of Directors and Shareholders of Berger One Hundred Fund, Inc.
- --------------------------------------------------------------------------------
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 financial highlights present fairly, in all
material respects, the financial position of Berger One Hundred Fund, Inc. (the
"Fund") at September 30, 1997, 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 three years in the
period then ended, 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, which included confirmation of securities at
September 30, 1997 by correspondence with the custodian and the application of
alternative auditing procedures where securities purchased had not been
received, provide a reasonable basis for the opinion expressed above. The
financial statements of the Fund for the year ended September 30, 1994 were
audited by other independent accountants whose report dated October 28, 1994
expressed an unqualified opinion on those financial statements.

Performance
During the fiscal year ended September 30, 1997, the Berger/BIAM International
Fund (the "Fund") delivered an annual total return to investors of 15.70%/1,2/.
This compares to 12.49% for the MSCI EAFE Index/3/. 

The main contributors to the performance during the year were the Positive
Banking, Healthcare and Growth in Telecommunications themes. There were a number
of good individual stock performances, which helped the portfolio, particularly
in the Healthcare Needs and Positive Banking Environment themes.

Many Positive Banking Environment stocks reported profit increases ranging from
14% to 52% during the period. This strong performance continued into the third
quarter.

Themes directed at the developing markets in the Far East have disappointed
throughout 1997. Increased Consumer Spending in the Pacific Basin and
Infrastructural Development have had a negative impact on the Fund for reasons
ranging from poor company results to the domino effect of financial crises and
currency weakness which caused poor performance by your stocks in the region.

Year in Review 
With the notable exception of the developing markets in the Pacific Basin and
Japan, equity markets world-wide have done very well during the last twelve
months. The ongoing U.S. bull market continues to boost international markets,
and, with American inflation apparently under control and no sign of imminent
interest-rate increases, European bourses have been hitting all-time highs.
Equity markets in general, declined sharply during August, in what can be
described as an almost inevitable correction after the strong gains earlier.
Most markets rebounded in September.

In the U.K., strong corporate earnings, particularly from the financial-services
sector, and the expectation of even more corporate restructuring by major
companies have been underpinning valuations. Towards the end of the period, U.K.
equities rallied, prompted by evidence of increased warmth towards the European
Monetary Union (EMU) which could mean earlier than expected interest rate cuts.

Other European markets also produced strong returns during the year, helped by
continuing optimism for economic recovery in Continental Europe and a positive
Wall Street backdrop. In contrast, the Pacific Rim markets collapsed during 1997
as investors fled from the continued currency weakness, soaring domestic
interest rates and policy indecision. Economic activity in Japan remains weak
and the Japanese market continues to disappoint, down 16% for the twelve months
ended September 30 1997.

Looking Ahead 
Despite the negative move in August, international equity markets have been very
strong for the third year in a row. These gains have pushed many company
valuations to very high levels and are occurring against an interest-rate
background which "if anything" is deteriorating. Many stocks, especially the
blue chips have been re-rated beyond their fundamental value.

After taking profits from some of the more highly priced U.K. and continental
European stocks in the portfolio, we invested the proceeds in a number of
selected Japanese holdings whose valuation levels are looking increasingly
reasonable. This does not imply a shift in our views on Japan from a
macro-economic perspective. We continue to monitor a number of Japanese
companies, which are restructuring, focusing on enhancing shareholder value and
delivering profit growth.

Currency volatility in the Southeast Asian markets has led to some panic selling
by investors. We do not feel that the current price levels of a number of the
companies in which we are invested fully reflect their true value. The
longer-term story for these stocks has not changed, but the impact of the recent
currency devaluations is going to take some time to work its way through the
markets. Consequently, we are constantly reviewing our investments in the area.

Our view on the U.K. and core Europe has changed little since last quarter. The
market perception on U.K. interest rates has undergone a complete turnaround
during September with all expectations of higher rates evaporating on the back
of the EMU speculation. EMU also continues to be the major focus in Europe.

We thank you for your investment in the Berger/BIAM International Fund.

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./ Performance figures are historical and, in part, reflect the performance of
a pool of assets advised by BIAM (Bank of Ireland Asset Management) for periods
before the Fund commenced operations on October 11, 1996, adjusted to reflect
any increased expenses associated with operating the Fund. The asset pool was
not registered with the Securities and Exchange Commission and therefore was not
subject to the investment restrictions imposed by law on registered mutual
funds. If the pool had been registered, its performance might have been
adversely affected.

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 Fund (one of the funds constituting Berger/BIAM
Worldwide Funds Trust, hereafter referred to as the "Fund") at September 30,
1997, the results of its operations, the changes in its net assets and the
financial highlights for the period November 7, 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 audit. We conducted our audit 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 audit provides a
reasonable basis for the opinion expressed above.

Performance
As of September 30, 1997, Berger Growth and Income Fund's (the "Fund") annual
total return was 34.56%/1/. The Fund underperformed the Standard & Poor's (S&P)
500/2/, which rose 40.43% over the same period.

The Fund underperformed the index primarily because of the nature of the stock
market. During the first six months of our fiscal year (October 1996 - March
1997), the market was dominated by the largest stocks, such as GE and Procter &
Gamble, which drive the performance of the S&P 500 Index. Investors, feeling
uncertain about the economy and interest rates, flocked to the large stocks,
because they offered high liquidity in case of an economic downturn. As a
result, the prices of these stocks were driven to what, in our opinion, were
unsustainable levels. We chose not to invest in the largest stocks and to stick
with our goal of seeking reasonably priced growth companies. That decision kept
the Fund from fully participating in the market's strong performance.

In April, however, the market began to broaden. Investors considered the largest
stocks' prices to be too expensive given their relatively low rates of revenue
growth - a viewpoint bolstered by cautionary earnings comments from companies
such as Coca-Cola and Gillette. Investors cast a wider net, seeking good growth
companies beyond those with the largest market capitalizations, a move that
benefited many of the companies owned by the Fund. As a result, our second half
total return of 25.50% was far stronger than our first half total return of
7.22%.

Year in Review 

We made some adjustments to the Fund's allocation of assets among growth
industries during the year. We increased holdings in technology from 11% one
year ago to 17.8% at year-end. We felt we were slightly underweighted in this
vital sector, which clearly is driving the U.S. and world economies. We added to
the financial sector, increasing holdings from 16% one year ago to 24.2% as of
September 30, 1997. We shifted some assets in this category from bank stocks to
insurance companies and specialty finance companies. We slightly reduced the
Fund's position in real estate investment trusts (REITs) since last year, but
have maintained our focus on full-service hotels and diversified office
buildings.

Since March 31, 1997, we have increased holdings in oil services because of
improving fundamentals, but are still down overall from our exposure one year
ago. We reduced our exposure to consumer staples and healthcare because we felt
the values in these sectors had reached unrealistic proportions.

To help bolster Fund yield over the year, we continued to purchase convertible
bonds where appropriate.

We believe in being fully invested at all times, so a higher percentage of cash
simply indicated a period in which we were unable to find suitable investments
for the Fund.

Looking Ahead 

If the market remains strong and maintains the broader focus of the past six
months,our portfolio should do very well. Two positive signs: the economy is
strong and interest rates have been stable since the last Federal Reserve Board
increase on March 25, 1997.

We would not be shocked to see the market drop over the next year, however, due
to some unforeseeable event, such as the Asian currency crisis that occurred in
August and September this past year. A correction would help wring some of the
excesses out of stock prices. Additionally, a correction would give us the
opportunity to buy more good companies for the Fund at lower prices.

Going forward, we believe that your Fund is properly diversified and structured
to benefit from broad, positive market performance.

We thank you for your investment in the Berger Growth and Income Fund.

Report of Independent Accountants

To the Board of Directors and Shareholders of Berger Growth and Income Fund, 
Inc.
- --------------------------------------------------------------------------------
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 financial highlights present fairly, in all
material respects, the financial position of Berger Growth and Income Fund, Inc.
(the "Fund") at September 30, 1997, 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 three years in
the period then ended, 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, which included
confirmation of securities at September 30, 1997 by correspondence with the
custodian and the application of alternative auditing procedures where
securities purchased had not been received, provide a reasonable basis for the
opinion expressed above. The financial statements of the Fund for the year ended
September 30, 1994 were audited by other independent accountants whose report
dated October 28, 1994 expressed an unqualified opinion on those financial
statements.

38   Annual Report September 30, 1997    The Berger Funds

                 Berger Balanced Fund   [PICTURE APPEARS HERE]
 
Co-Portfolio               Patrick S. Adams
Managers' Commentary       John B. Jares

Investment Approach
The Berger Balanced Fund (the "Fund") is our most conservative fund - our
"comfort" Fund. We always will have at least 25% of Fund net assets invested in
stocks and 25% in fixed-income securities in order to achieve our objective of
providing capital appreciation and current income. 

When we consider the stock market attractive, and when the number of potentially
profitable investments is plentiful, we may invest up to 75% of Fund net assets
in stocks. We primarily seek reasonably priced stocks of mid to large cap
companies that have a history of strong, consistent, and predictable earnings,
strong management, competitive products and services, and conservatively
financed balance sheets.

When we don't find stocks as attractive, or when the market is more volatile, we
will reduce our stock holdings and increase our investment in fixed-income
securities such as U.S. government and corporate debt securities, convertible
securities, and preferred stock.

Initial Trading 
We are building the portfolio for the Balanced Fund on a cautious, but
optimistic basis. Subsequent to year end, we immediately invested the majority
of total Fund assets in defensive fixed-income securities, i.e., securities with
shorter maturities that pay interest. This gives us the liquidity and
flexibility to move dollars into more attractive fixed-income securities or
stocks as opportunities arise, while we generate current income for our
shareholders.

On the stock side, we are investing slowly, and, at least initially, in the
promising growth companies we already have identified through bottom-up research
for other Berger Funds. For example, two stocks we're high on in the Berger One
Hundred Fund - Household International, a diversified financial services firm;
and Safeway, a grocery store - have been purchased subsequent to year end for
the Berger Balanced Fund portfolio. We will add to our stock holdings as we
identify stocks that meet our selection criteria. 

Although we have been in a prolonged bull market that makes reasonably priced
companies harder to find, we believe there still are many good opportunities
available. One significant advantage of this Fund is that when we feel there are
not as many good stock investments available, we can shift assets to
fixed-income securities.

We are optimistic about the market over the next several quarters, even though
there is the risk that the Federal Reserve Board could raise interest rates if
it feels the economy is growing at too brisk a pace. By investing in stocks as
well as some bonds, however, the Fund is designed to weather a variety of market
conditions. You might think of this Fund as a "Fund for all seasons." It is a
more conservative way to take advantage of the Berger growth investment
philosophy - and may provide critical diversification in the event of a stock
market correction.

Thank you for your investment in the Berger Balanced Fund.

Report of Independent Accountants

To the Board of Trustees and Shareholders of Berger Investment Portfolio Trust
- --------------------------------------------------------------------------------

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Berger Small Company Growth Fund,
Berger New Generation Fund and Berger Balanced Fund (constituting Berger
Investment Portfolio Trust, hereafter referred to as the "Trust") at September
30, 1997, the results of each of their operations for each of the periods
indicated, the changes in each of their net assets for each of the periods
indicated and the financial highlights for each of the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Trust'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, 1997 by correspondence with the custodian and the application of
alternative auditing procedures where securities purchased had not been
received, provide a reasonable basis for the opinion expressed above. The
financial statements of Berger Small Company Growth Fund for the period ended
September 30, 1994 were audited by other independent accountants whose report
dated October 28, 1994 expressed an unqualified opinion on those financial
statements.

1  Organization and Significant Accounting Policies

Organization
The Berger New Generation Fund ("BNG"), Berger Small Company Growth Fund
("BSCG"), Berger Small Cap Value Fund ("BSCV"), Berger One Hundred Fund ("100"),
Berger/BIAM International Fund ("BBIF"), Berger Growth and Income Fund ("BG&I")
and Berger Balanced Fund ("BBAL")(individually the "Fund" and collectively, the
"Funds") are diversified open-end management investment companies registered
under the Investment Company Act of 1940 (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 BBAL
and BG&I which also pursue current income. 

The 100 and BG&I are corporations registered in the State of Maryland. BSCG, BNG
and BBAL are separate series established under the Berger Investment Portfolio
Trust, a Delaware business trust ("BIP Trust"). BBAL commenced investment
operations on September 30, 1997. BSCV is the only portfolio established under
the Berger Omni Investment Trust ("OMNI Trust"), a Massachusetts business trust
and the BBIF (which commenced investment operations on November 7, 1996) 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 paid by
Berger Associates, Inc. ("Berger") or BBOI Worldwide LLC ("BBOI").

Prior to February 14, 1997, the BSCV and OMNI Trust were known as The Omni
Investment Fund. On February 14, 1997, all of the outstanding shares of The Omni
Investment Fund were designated Institutional Shares ("BSCV; Inst") of the BSCV
series and a separate class of shares, Investor Shares ("BSCV; Inv"), were
offered. Both classes of shares have identical rights to earnings, assets and
voting privileges.

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 (15.3% at September 30, 1997). 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 portfolio 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
asked prices. Securities traded in the over-the-counter market are valued at the
mean between their current bid and asked 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.

Generally, trading in foreign securities markets is substantially completed each
day at various times prior to the close of the Exchange. The values of foreign
securities used in computing the net asset value of the shares in the Fund are
determined as of the earlier of such market close or the closing time of the
Exchange. Occasionally, events affecting the value of such securities may occur
between the times at which they are determined and the close of the Exchange, or
when the foreign market on which such securities trade is closed but the
Exchange is open, which will not be reflected in the computation of net asset
value. If during such periods, events occur which 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.

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

Federal Income Taxes 
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.

- --------------------------------------------------------------------------------
1 Organization and Significant Accounting Policies - Continued 
- --------------------------------------------------------------------------------

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 and distributions to shareholders are recorded on the
ex-dividend date, except if the ex-dividend date has passed, certain dividends
from foreign securities are reported as soon as the Fund is informed of the ex-
dividend date. Interest income is recorded on the accrual basis and includes
amortization of discounts and premiums. 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 class), gains and
losses of the BSCV are allocated daily to each class of shares based upon the
proportion of relative net assets represented by each class as a percentage of
total net assets of the BSCV. Expenses directly attributable to a specific class
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 and annual operating expenses of the Portfolio
including the investment advisory fee, custodian fees, independent accountants'
fees, record keeping and pricing agent fees. Such investment income and expenses
are allocated on the day the expense is incurred in proportion to the prior
day's relative net assets of BBIF and other investors in the Portfolio.

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

Use of Estimates 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and ass umptions
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 BNG, BSCG, BSCV, 100, BG&I and
BBAL pursuant to agreements which provide for an investment advisory fee to be
paid to Berger at the following annual rates as a percentage of average daily
net assets; BNG, BSCG and BSCV - .90%, 100 and BG&I - .75% and BBAL - .70%.
Berger has delegated the day-to-day investment management of BSCV to Perkins,
Wolf & McDonnell ("PWM"). As compensation for services rendered to BSCV, PWM
receives a sub-advisory fee from Berger at an annual rate of .90% of the BSCV's
average daily net assets up to $75 million; .50% of average daily net assets
between $75 million and $200 million and .20% of average daily net assets in
excess of $200 million. All investment advisory fees are accrued daily and paid
monthly. Berger has also agreed to voluntarily waive its advisory fee for BNG
and BBAL to the extent that the each Fund's normal operating expenses in any
fiscal year (including the management fee and the 12b-1 fee, but excluding
brokerage commissions, interest, taxes and extraordinary expenses) exceeds 1.90%
and 1.50%, respectively, of each Fund's average daily net assets for that fiscal
year.

Pursuant to an Administrative Services Agreement, whereby BBOI serves as
the administrator to BBIF, the Fund 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 the Fund's average daily net
assets. Under the Agreement, BBOI 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, printing and mailing to shareholders of prospectuses and
other required communication and certain other administrative services. BBOI has
delegated the administration of the Fund to Berger. For such services, BBOI has
agreed to compensate Berger with a sub-administration annual fee equal to 0.25%
of the Fund's average daily net assets. Such fee has been voluntarily waived by
Berger for the period ended September 30, 1997. 

The Funds have adopted plans pursuant to Rule 12b-1 under the Investment Company
Act of 1940 (the "Plans"). The BSCV Plan, which became effective February 14,
1997, applies only to BSCV; Inv. 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 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 BNG, BSCG, BSCV, 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 1% of the average daily net assets of each Fund,
computed daily and payable monthly. The Funds have also entered into
recordkeeping and pricing agreements with Investors Fiduciary Trust Company
("IFTC"), who also serves as the Funds' custodian and transfer agent. The
recordkeeping and pricing agreement provides 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 and pricing, or 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 custodianor 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. 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. For the period ended September
30, 1997, the 100, BG&I and BSCG, earned $352,000, $8,000 and $14,000 of such
credits, respectively.

Certain officers and 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 received aggregate directors'/trustees' fees and reimbursed
expenses from the Funds totaling $357,000 for the fiscal periods ended September
30, 1997.

Futures, Forward Contracts and Options 
Each Fund may hold certain types of futures, 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 the Funds' hedging strategy unsuccessful. In
addition, there can be no assurance that a liquid secondary market will exist
for the instrument. Realized gains or losses on these securities are included in
Net Realized Gain (Loss) on Securities Transactions in the Statements of
Operations. A summary of options transactions for the Berger Small Cap Value
Fund for the fiscal period ended September 30, 1997 is listed below:

Federal Income Tax Status
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. Of the ordinary income distributions
declared for the year ended September 30, 1997, 100% qualified for the dividends
received deduction available to the corporate shareholders of the Berger Growth
and Income Fund.

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

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 for
net operating losses. 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 period ended September 30, 1997 the following reclassifications were
made:

</TABLE>

At September 30, 1997, BNG had capital loss carryovers in the amount of
$7,485,327, expiring on September 30, 2005, which may be used to offset future
realized capital gains for Federal income tax purposes. 

- --------------------------------------------------------------------------------
4 Transactions With Affiliates 
- --------------------------------------------------------------------------------

During February 1997, pursuant to a policy adopted by the Funds'
directors/trustees, Berger reimbursed the 100 Fund $794,000 as a result of a
security trading error. 

- --------------------------------------------------------------------------------
5 Line of Credit 
- --------------------------------------------------------------------------------

In July 1997, BNG, BSCG, BSCV, 100, BG&I and the Portfolio entered into an
ongoing agreement with certain banks which allows the Funds, collectively, to
borrow up to $150 million for temporary or emergency purposes. Interest on the
borrowings, if any, is charged to the specific fund executing the borrowing at
the Federal Funds Rate plus 75 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.

- --------------------------------------------------------------------------------
6 Change of Fiscal Year and Independent Accountants 
- --------------------------------------------------------------------------------

Effective April 11, 1997, the trustees of the OMNI Trust approved changing
BSCV's fiscal year end from December 31 to September 30 and the trustees of BBWF
Trust approved changing BBIF's fiscal year end from July 31 to September 30.
Additionally, the trustees of OMNI Trust appointed Price Waterhouse LLP as
independent accountants for BSCV for the fiscal period ended September 30, 1997.

- --------------------------------------------------------------------------------
7 Subsequent Event 
- --------------------------------------------------------------------------------

On October 20, 1997, the trustees of BIP Trust approved closing BSCG to new
investors effective November 17, 1997.

- --------------------------------------------------------------------------------
8 Other Matters (Unaudited) 
- --------------------------------------------------------------------------------

A special meeting of shareholders of The OMNI Investment Fund was held
on February 13, 1997, at which shareholders approved a number of
proposals which facilitated BSCV becoming part of the Berger Funds
family of mutual funds. The proposals approved included the following:

Proposal 1. Election of ten new individuals as trustees of the OMNI
Trust, each who also serve as trustees of other Berger Funds;

Proposal 2. Approval of a new Investment Advisory Agreement with
Berger, pursuant to which BSCV pays Berger a fee at the annual rate of
0.90% of BSCV's average daily net assets for its advisory services;

Proposal 3. Approval of a new Sub-Advisory Agreement between Berger and PWM,
pursuant to which Berger pays PWM a fee at the annual rate of 0.90% of the first
$75 million of average daily net assets of BSCV, 0.50% of the next $125 million,
and 0.20% of any amount in excess of $200 million for sub-advisory services;

Proposal 4. Approval of amendments to The OMNI Investment Fund's Declaration of
Trust to permit the establishment of multiple classes of shares.

The following is a report of the votes cast:

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

To the Board of Trustees and Investors of 
Berger/BIAM International Portfolio 
- --------------------------------------------------------------------------------

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 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, 1997, and the results of its
operations, the changes in its net assets and the supplementary data 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 supplementary 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 audit. We conducted our audit 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 audit, which included confirmation of securities at
September 30, 1997 by correspondence with the custodian and brokers, and the
application of alternative auditing procedures where securities purchased had
not been received, provides a reasonable basis for the opinion expressed above.

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 an 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 paid by BBOI Worldwide
LLC ("BBOI"), the investment advisor of the Portfolio. The Portfolio commenced
investment operations on October 11, 1996 ("Commencement of 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 is 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. 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 the United States.

The Portfolio is advised by BBOI, which has delegated daily portfolio management
of the Portfolio to BIAM. Berger Associates, Inc. ("Berger") and BIAM each own
50% of BBOI.

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

Investment Valuation 
The Portfolio's securities and other assets are valued at the close of the
regular trading session of the New York Stock Exchange (the "Exchange")
(normally 4:00 p.m. New York time) each day the Exchange is open. The
Portfolio's securities and other assets are valued as follows: securities listed
or traded primarily on foreign exchanges, national exchanges and the Nasdaq
Stock market are valued at the last sale price on such markets, or, if such a
price is lacking for the trading period immediately preceding the time of
determination, such securities are valued at the mean of their current bid and
asked prices. Securities that are traded in the over-the-counter market are
valued at the mean between their current bid and asked prices. The market value
of individual securities held by the Portfolio are determined by using pricing
services which provide market prices to other mutual funds or, as needed, by
obtaining market quotations from independent broker/dealers. Short-term money
market securities maturing within 60 days are valued on the amortized cost
basis, which approximates market value. Securities and assets for which
quotations are not readily available are valued at fair values determined in
good faith pursuant to consistently applied procedures established by the
trustees.

Generally, trading in foreign securities markets is substantially completed each
day at various times prior to the close of the Exchange. The values of foreign
securities used in computing the net asset value of the shares in the Portfolio
are determined as of the earlier of such market close or the closing time of the
Exchange. Occasionally, events affecting the value of such securities may occur
between the times at which they are determined and the close of the Exchange, or
when the foreign market on which such securities trade is closed but the
Exchange is open, which will not be reflected in the computation of net asset
value. If during such periods, events occur which 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.

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 trade date. Gains and losses
are computed on the identified cost basis for both financial statement and
Federal income tax purposes for all securities. Dividend income and
distributions to investors are recorded on the

International
Portfolio
 
1 Organization and Significant Accounting Policies-Continued

ex-dividend date, except if the ex-dividend date has passed, certain dividends
from foreign securities are recorded as soon as the Portfolio is informed of the
ex-dividend date. Dividend income is recorded net of foreign taxes withheld
where recovery of such taxes is not assured. Interest income is recorded on the
accrual basis and includes amortization of discounts and premiums.

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.

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. Risks 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.

2 Agreements 

BBOI renders investment advisory services to the Portfolio pursuant to an
agreement which provides for an investment advisory fee to be paid to BBOI at
the annual rate of .90 of 1% of the Portfolio's average daily net assets. Until
at least April 30, 1998, BBOI has agreed voluntarily 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 has delegated the
daily investment management of the Portfolio to BIAM. For such services, BBOI
pays BIAM a sub-advisory fee equal to .45% of the average daily net assets of
the Portfolio. Such sub-advisory fee has been voluntarily waived by BIAM from
the Commencement of Investment Operations through September 30, 1997, except for
an amount payable on the Citizens NH converted assets.

Investors Fiduciary Trust Company ("IFTC") has been appointed to provide
recordkeeping and pricing services to the Portfolio, including calculating the
net asset value of the Portfolio, and to perform certain accounting and
recordkeeping functions required by the Portfolio. In addition, IFTC has been
appointed to serve as the Portfolio's custodian and transfer agent. For
custodian, recordkeeping and pricing services, the Portfolio pays a fee directly
to IFTC based on a percentage of its net assets, subject to certain minimums,
and reimburses IFTC for certain out-of-pocket expenses. IFTC's fees for custody,
recordkeeping and pricing, or 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 or by credits received from directed brokerage
transactions. For the period from Commencement of Investment Operations through
September 30, 1997, the Fund received $66,350 in earnings and brokerage credits
which offset the fees payable to IFTC for services rendered.

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 (which consists of the One Hundred Fund, the Growth and Income
Fund, the Small Company Growth Fund, the New Generation Fund, the Small Cap
Value Fund and the Balanced Fund) and Berger/BIAM Portfolio, which includes an
annual fee component and a per meeting component. Such fees are allocated
directly to the Portfolio and, therefore, indirectly to each fund. Trustees'
fees and expenses during the period from Commencement of Investment Operations
through September 30, 1997, totaled $38,602.

- --------------------------------------------------------------------------------
In July 1997, the Portfolio, along with the Berger New Generation Fund, Berger
Small Company Growth Fund, Berger Small Cap Value Fund, Berger One Hundred Fund
and Berger Growth and Income Fund (the "Funds"), entered into an ongoing
agreement with certain banks which allows the Funds and the Portfolio,
collectively, to borrow up to $150 million, subject to certain conditions, for
temporary or emergency purposes. Interest on any borrowings, if any, is charged
to the specific fund executing the borrowing at the Federal Funds Rate plus 75
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. 

5 Change of Fiscal Year 
- --------------------------------------------------------------------------------
Effective April 11, 1997, the trustees of the Trust approved changing the fiscal
year end of the Portfolio from July 31 to September 30.
