BERGER/BIAM INTERNATIONAL FUND
PORTFOLIO MANAGER'S LETTER

Dear Shareholder,

Bank of Ireland Asset Management (U.S.) Limited (BIAM)* is an active
international equity manager, pursuing a value style through the use of
fundamental analysis.

We are bottom-up stock pickers, selecting stocks within a framework of economic
themes.  These broad-based trends are derived from a wide spectrum of global
events, which can be social, economic and/or technological, in nature.  They are
an important part of the process that ultimately allows us to identify the ideas
that we believe will generate above average growth over the long term.

FUND REVIEW:

During the early part of the year no individual theme made a significant
contribution--either positive or negative--to overall performance although there
were a number of good individual stock performances which helped the portfolio,
particularly in the Healthcare Needs and Positive Banking Environment themes. 
In Healthcare, Roche, Zeneca, Glaxo-Wellcome and Novartis did well during the
first part of the year and continued to improve through the end of July.

In April, Novartis purchased Merck's agribusiness division and in May it
released its first-quarter sales figures which revealed an increase of 8%,
considerably ahead of expectations.  This was seen as evidence that the benefits
of the merger were having a quicker-than-expected impact on the company's
performance.  The market received this news very well and Novartis' share price
rose by 29% over the second quarter.  Both Zeneca and Glaxo-Wellcome continued
to prosper, also based on optimism for prospective sales growth from new drugs.

Positive Banking Environment stocks Lloyds TSB, ABN-Amro and National Australia
Bank reported profit increases ranging from 14% to 52% during the period.  This
strong performance continued into the second three months of 1997, with Banco de
Santander posting good first quarter results and HSBC Holdings gaining 29% over
the period, assisted by the strong performance of the Hong Kong market in
general.

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. This has
taken place for a variety of reasons ranging from poor company results--as was
the case with HM Sampoerna which announced poor sales forecasts--to the domino
effect of financial crises which caused poor performance by Bangkok Bank.

The currency hedging program again added value over the period.  At the end of
July hedges were in place against the British Pound, the Deutschemark, the Swiss
Franc and the Dutch Guilder.  Approximately 17% of the portfolio is currently
hedged.

ECONOMIC & MARKET REVIEW

With the notable exception of the developing markets in the Pacific Basin,
equity markets worldwide have thus far done well during 1997.  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-highs over the last six
months.

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.  The initial actions of the
country's new Labour government have been a source of encouragement to the
market, although the administration's fiscal and monetary policies will be
analyzed very closely.

The weakness of the Deutschemark stimulated a recovery in Germany's
export-oriented manufacturing sector in the early part of the year and during
the second quarter, foreign orders have increased at a steady pace.  Their
domestic economy remains in the doldrums, however, and unemployment remains at,
or close to record levels.

Far Eastern markets performed poorly during the first three months due to fears
about the upward direction of U.S. interest rates and continued net outflows by
foreign investors.  During the second quarter in Malaysia, concern about strong
consumer spending, a rising level of imports, high labor costs and a possible
oversupply of property all contributed to drive the market downwards.  The
ongoing financial crisis in Thailand resulted in a 25% decline in the market
during the latter part of the period.  

The Japanese market, on the other hand, rebounded strongly, gaining 22% during
the second quarter.  Despite continued speculation that interest rates are set
to rise, coupled with a mixed picture on the domestic economy's future growth
prospects, foreigners continue to increase their investments in Japan.  Little
attention is being paid to the current paltry state of the financial sector
where banks are continuing to struggle under the burden of their bad debts which
are estimated, by the most optimistic of forecasters, to absorb profits for the
next 3.3 years.

OUTLOOK:

Our outlook for the remainder of the year remains the same.  The low-growth,
low-inflationary environment, which prevails globally, will continue to provide
a favorable backdrop for equity investments.  Nevertheless the upward movement
of most markets has driven up valuations relative to earnings growth and this
fact remains uppermost in our minds.  These gains have pushed many multiples to
very high levels and are occurring against an interest rate background which, if
anything, is deteriorating.  Many stock prices, especially the blue chips, and
even more so, some financials have increased beyond their fundamental values.

Based on relative valuations levels, this has led us to move from some of the
more highly priced U.K. and continental European stocks, switching the proceeds
into a number of selected Japanese holdings where valuation levels are looking
increasingly reasonable.

                                      3

Overall, global economic conditions remain on the positive side, with few
general signs of real inflationary pressures.  The only exceptions to this are
the U.K. where there have been some interest rate rises and where the currency
is becoming less competitive, and some of the smaller Far Eastern countries in
recent months. The debate on the introduction of the Euro in 1999 and the likely
list of initial participants continues to be a major focus in Europe but the
general consensus is that European monetary union will go ahead on schedule.

Thank you for your continued confidence and investment in the Fund.

FOOTNOTE TO LINE GRAPH AND AVERAGE ANNUAL TOTAL RETURNS
Total return data for the Fund for periods prior to October 11, 1996, reflect 
the performance of the pool of assets transferred on that date into the 
Berger/BIAM International Portfolio in which all of the Fund's assets are 
invested, adjusted at that time for any increase in expenses anticipated in 
operating the Fund, including the Fund's pro rata share of the aggregate 
annual operating expenses, net of fee waivers, of the Portfolio.  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.  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.

BERGER/BIAM INTERNATIONAL FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
JULY 31, 1997


1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION
     The Berger/BIAM International 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 Fund and the Trust are registered under the
Investment Company Act of 1940, as amended, as open-end management investment
companies.  The Trust is authorized to issue an unlimited number of shares of
beneficial interest in series or portfolios.  Currently, the series comprising
the Fund, International Equity 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 Fund
commenced investment operations on November 7, 1996 ("Commencement of Investment
Operations").

     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 (19% at July 31, 
1997).  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 
portfolio 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 paid by BBOI Worldwide LLC, the advisor of the 
Portfolio (the "Advisor").  The Advisor has delegated the daily portfolio 
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 
Associates, Inc. ("Berger") also owns 50% of the Advisor.

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
     The price of the Fund's shares is based on the net asset value of the Fund,
which is determined 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
that the Exchange is open.  The per share net asset value of the Fund is
determined by dividing the total value of its assets, less liabilities, by the
total number of shares outstanding.  Since the Fund will invest all of its
investable assets in the Portfolio, the value of the Fund'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 Statement which accompany these Financial
Statements for the Fund.

INCOME AND EXPENSES
     As an investor in the Portfolio, the Fund 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 the Fund and other
investors in the Portfolio.

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.

                                      9

<PAGE>

DIVIDENDS AND DISTRIBUTIONS
     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 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 treatments for
net operating losses and expiring capital loss carryforwards.  Accordingly,
these permanent differences in the character of income and distributions between
financial statements and tax basis will be reclassified to paid-in-capital.  At
July 31, 1997, no such differences existed.

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 0.45% of its
average daily net assets or the Advisor's annual cost to provide or procure such
services plus 0.02% 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, printing and mailing to shareholders of prospectuses and other
required communication 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.    

     Additionally, the Fund has adopted a plan pursuant to Rule 12b-1 under the
Investment Company Act of 1940 (the "Plan").  The Plan provides for the payment
to Berger of a 12b-1 fee of .25 of 1% per annum of the Fund's average daily net
assets to finance activities primarily intended to result in the sale of the
Fund's shares.  The plan provides that such payments will be made to Berger as
compensation rather than reimbursement for actual expenses incurred to promote
the sale of the Fund's shares.

     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 that it requires.  In addition, IFTC has been appointed to serve as
the Fund's custodian, transfer agent and dividend disbursing agent.

     Certain officers and trustees of the Trust are officers and directors of
the Advisor or Sub-Advisor.  Trustees who are not affiliated with the
Portfolio's Advisor or Sub-Advisor are compensated for their services according
to a fee schedule, allocated among the Berger Funds 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 the Fund.

3.   CHANGE OF FISCAL YEAR

     Effective April 11, 1997, the trustees of the Trust changed the fiscal year
end of the Fund from July 31 to September 30.

BERGER/BIAM INTERNATIONAL PORTFOLIO
Notes to Financial Statements (Unaudited)
July 31, 1997

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, the investment advisor of the Portfolio ("BBOI").  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.  

     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 will be 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.  All assets and
liabilities initially expressed in terms of non-U.S. dollar currencies are
translated into U.S. dollars at the prevailing market rates as quoted by one or
more banks or dealers shortly before the close of the Exchange.  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.

                                     19

<PAGE>

FEDERAL INCOME TAXES
     The Portfolio intends to be treated as 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.

SECURITY GAINS AND LOSSES
     Gains and losses are computed on the identified cost basis for both
financial statement and Federal income tax purposes for all securities.  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.  Interest income is recorded on the accrual
basis and includes amortization of discounts.

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.

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.

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 portfolio 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 Operations through July 31, 1997, except for the 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 Operations through
July 31, 1997, the Fund received $57,888 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
the Advisor or BIAM.  Trustees who are not affiliated with the Advisor or BIAM
are compensated for their services according to a fee schedule, allocated among
the Berger Funds 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 operations through July 31, 1997, totaled
$36,109.

3.   INVESTMENT TRANSACTIONS

PURCHASES AND SALES

INTERNATIONAL EQUITY FUND
PORTFOLIO MANAGER'S LETTER



Dear Shareholder,

Bank of Ireland Asset Management (U.S.) Limited (BIAM)* is an active 
international equity manager, pursuing a value style through the use of 
fundamental analysis. 

We are bottom-up stock pickers, selecting stocks within a framework of 
economic themes.  These broad-based trends are derived from a wide spectrum 
of global events, which can be social, economic and/or technological, in 
nature.  They are an important part of the process that ultimately allows us 
to identify the ideas that we believe will generate above average growth over 
the long term.

FUND REVIEW:

During the early part of the year no individual theme made a significant 
contribution--either positive or negative--to overall performance although 
there were a number of good individual stock performances which helped the 
portfolio, particularly in the Healthcare Needs and Positive Banking 
Environment themes.  In Healthcare, Roche, Zeneca, Glaxo-Wellcome and 
Novartis did well during the first part of the year and continued to improve 
through the end of July.

In April, Novartis purchased Merck's agribusiness division and in May it 
released its first-quarter sales figures which revealed an increase of 8%, 
considerably ahead of expectations.  This was seen as evidence that the 
benefits of the merger were having a quicker-than-expected impact on the 
company's performance.  The market received this news very well and Novartis' 
share price rose by 29% over the second quarter.  Both Zeneca and 
Glaxo-Wellcome continued to prosper, also based on optimism for prospective 
sales growth from new drugs.

Positive Banking Environment stocks Lloyds TSB, ABN-Amro and National 
Australia Bank reported profit increases ranging from 14% to 52% during the 
period.  This strong performance continued into the second three months of 
1997, with Banco de Santander posting good first quarter results and HSBC 
Holdings gaining 29% over the period, assisted by the strong performance of 
the Hong Kong market in general.

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. This has 
taken place for a variety of reasons ranging from poor company results--as 
was the case with HM Sampoerna which announced poor sales forecasts--to the 
domino effect of financial crises which caused poor performance by Bangkok 
Bank.

The currency hedging program again added value over the period.  At the end 
of July hedges were in place against the British Pound, the Deutschemark, the 
Swiss Franc and the Dutch Guilder.  Approximately 17% of the portfolio is 
currently hedged.

ECONOMIC & MARKET REVIEW

With the notable exception of the developing markets in the Pacific Basin, 
equity markets worldwide have thus far done well during 1997.  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-highs over the last six 
months.

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.  The 
initial actions of the country's new Labour government have been a source of 
encouragement to the market, although the administration's fiscal and 
monetary policies will be analyzed very closely.

The weakness of the Deutschemark stimulated a recovery in Germany's 
export-oriented manufacturing sector in the early part of the year and during 
the second quarter, foreign orders have increased at a steady pace.  Their 
domestic economy remains in the doldrums, however, and unemployment remains 
at, or close to record levels.

Far Eastern markets performed poorly during the first three months due to 
fears about the upward direction of U.S. interest rates and continued net 
outflows by foreign investors.  During the second quarter in Malaysia, 
concern about strong consumer spending, a rising level of imports, high labor 
costs and a possible oversupply of property all contributed to drive the 
market downwards.  The ongoing financial crisis in Thailand resulted in a 25% 
decline in the market during the latter part of the period.  

The Japanese market, on the other hand, rebounded strongly, gaining 22% 
during the second quarter.  Despite continued speculation that interest rates 
are set to rise, coupled with a mixed picture on the domestic economy's 
future growth prospects, foreigners continue to increase their investments in 
Japan.  Little attention is being paid to the current paltry state of the 
financial sector where banks are continuing to struggle under the burden of 
their bad debts which are estimated, by the most optimistic of forecasters, 
to absorb profits for the next 3.3 years.

OUTLOOK:

Our outlook for the remainder of the year remains the same.  The low-growth, 
low-inflationary environment, which prevails globally, will continue to 
provide a favorable backdrop for equity investments.  Nevertheless the upward 
movement of most markets has driven up valuations relative to earnings growth 
and this fact remains uppermost in our minds.  These gains have pushed many 
multiples to very high levels and are occurring against an interest rate 
background which, if anything, is deteriorating.  Many stock prices, 
especially the blue chips, and even more so, some financials have increased 
beyond their fundamental values.

Based on relative valuations levels, this has led us to move from some of the 
more highly priced U.K. and continental European stocks, switching the 
proceeds into a number of selected Japanese holdings where valuation levels 
are looking increasingly reasonable.

                                     3

Overall, global economic conditions remain on the positive side, with few 
general signs of real inflationary pressures.  The only exceptions to this 
are the U.K. where there have been some interest rate rises and where the 
currency is becoming less competitive, and some of the smaller Far Eastern 
countries in recent months. The debate on the introduction of the Euro in 
1999 and the likely list of initial participants continues to be a major 
focus in Europe but the general consensus is that European monetary union 
will go ahead on schedule.

Thank you for your continued confidence and investment in the Fund.

FOOTNOTE TO LINE GRAPH AND AVERAGE ANNUAL TOTAL RETURNS  

Total return data for the Fund for periods prior to October 11, 1996, reflect 
the performance of the pool of assets transferred on that date into the 
Berger/BIAM International Portfolio in which all of the Fund's assets are 
invested, adjusted at that time for any increase in expenses anticipated in 
operating the Fund, including the Fund's pro rata share of the aggregate 
annual operating expenses, net of fee waivers, of the Portfolio.  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.  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.

INTERNATIONAL EQUITY FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
JULY 31, 1997


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 Fund and the Trust are 
registered under the Investment Company Act of 1940, as amended, as open-end 
management investment companies.  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 Fund commenced investment 
operations on October 11, 1996 ("Commencement of Investment Operations").
 
 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 (6% at July 31, 
1997).  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 
portfolio 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 paid by BBOI Worldwide LLC, the advisor of the 
Portfolio (the "Advisor").  The Advisor has delegated the daily portfolio 
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 
Associates, Inc. ("Berger") also owns 50% of the Advisor.

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

 The price of the Fund's shares is based on the net asset value of the Fund, 
which is determined 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 that the Exchange is open.  The per share net asset value of the Fund is 
determined by dividing the total value of its assets, less liabilities, by 
the total number of shares outstanding.  Since the Fund will invest all of 
its investable assets in the Portfolio, the value of the Fund'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 Statement which accompany these 
Financial Statements for the Fund.

INCOME AND EXPENSES

 As an investor in the Portfolio, the Fund 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 the Fund and other 
investors in the Portfolio.


                                     9

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.

DIVIDENDS AND DISTRIBUTIONS

 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 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 treatments for net operating losses and expiring capital loss 
carryforwards.  Accordingly, these permanent differences in the character of 
income and distributions between financial statements and tax basis will be 
reclassified to paid-in-capital.  At July 31, 1997, no such differences 
existed.

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 
0.35% of its average daily net assets or the Advisor's annual cost to provide 
or procure such services plus 0.02% 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 communication and certain 
other administrative services.  Effective June 20, 1997, the Advisor 
voluntarily reduced the administrative fee payable by the Fund to 0.10% of 
the Fund's 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. 
The Advisor has delegated the administration of the Fund to Berger. For such 
services, the Advisor pays Berger a subadministration fee equal to 0.25% of 
the Fund's average daily net assets.

 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 that it requires.  In addition, IFTC has been appointed to serve as 
the Fund's custodian, transfer agent and dividend disbursing agent.

 Certain officers and trustees of the Trust are officers and directors of the 
Advisor or Sub-Advisor.  Trustees who are not affiliated with the Portfolio's 
Advisor or Sub-Advisor are compensated for their services according to a fee 
schedule, allocated among the Berger Funds and Berger/BIAM Portfolio, which 
includes an annual fee component and a per meeting component.  Such fees are 
allocated directly to the Portfolio and indirectly to the Fund.

3. CHANGE OF FISCAL YEAR AND NAME

 Effective April 11, 1997, the trustees of the Trust changed the fiscal year 
end of the Fund from July 31 to September 30.  Effective June 20, 1997, the 
trustees of the Trust changed the name of the Fund from the Berger/BIAM 
International Institutional Fund to the International Equity Fund.

BERGER/BIAM INTERNATIONAL PORTFOLIO
Notes to Financial Statements (Unaudited)
July 31, 1997


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, the investment advisor of the Portfolio ("BBOI").  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.

   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 will be 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.  All assets and 
liabilities initially expressed in terms of non-U.S. dollar currencies are 
translated into U.S. dollars at the prevailing market rates as quoted by one or 
more banks or dealers shortly before the close of the Exchange.  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.

FEDERAL INCOME TAXES
   The Portfolio intends to be treated as 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.

SECURITY GAINS AND LOSSES
   Gains and losses are computed on the identified cost basis for both 
financial statement and Federal income tax purposes for all securities.  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.  Interest income is recorded on the accrual 
basis and includes amortization of discounts.

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.

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.

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 portfolio 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 Operations through July 31, 1997, except for the amount
payable on the Citizens NH converted assets.


                                      20
<PAGE>

   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 Operations through 
July 31, 1997, the Fund received $57,888 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 the 
Advisor or BIAM.  Trustees who are not affiliated with the Advisor or BIAM are 
compensated for their services according to a fee schedule, allocated among the 
Berger Funds 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 operations through July 31, 1997, totaled 
$36,109.

3.  INVESTMENT TRANSACTIONS

PURCHASES AND SALES
   Purchases and sales of investment securities (excluding short-term 
securities) during the period from Commencement of Investment Operations to 
July 31, 1997 were as follows:

               Purchase of                       Sales of
         Investment Securities            Investment Securities
         ---------------------            ---------------------
              $ 89,505,618                      $ 7,790,854

   There were no purchases or sales of long-term U.S. Government securities 
during the period.

   At July 31, 1997, the composition of unrealized appreciation (the excess of 
value over tax cost) and unrealized depreciation (the excess of tax cost over 
value) for securities held was as follows:

            Appreciation     Depreciation           Net 
            ------------     ------------     -------------
             $11,187,925      $2,387,401        $8,800,524

4.  CHANGE OF FISCAL YEAR

   Effective April 11, 1997, the trustees of the Trust changed the fiscal year 
end of the Portfolio from July 31 to September 30.

BERGER/BIAM INTERNATIONAL CORE FUND
PORTFOLIO MANAGER'S LETTER

Dear Shareholder,

Bank of Ireland Asset Management (U.S.) Limited (BIAM)* is an active
international equity manager, pursuing a value style through the use of
fundamental analysis.

We are bottom-up stock pickers, selecting stocks within a framework of economic
themes.  These broad-based trends are derived from a wide spectrum of global
events, which can be social, economic and/or technological, in nature.  They are
an important part of the process that ultimately allows us to identify the ideas
that we believe will generate above average growth over the long term.

FUND REVIEW:

During the early part of the year no individual theme made a significant
contribution--either positive or negative--to overall performance although there
were a number of good individual stock performances which helped the portfolio,
particularly in the Healthcare Needs and Positive Banking Environment themes. 
In Healthcare, Roche, Zeneca, Glaxo-Wellcome and Novartis did well during the
first part of the year and continued to improve through the end of July.

In April, Novartis purchased Merck's agribusiness division and in May it
released its first-quarter sales figures which revealed an increase of 8%,
considerably ahead of expectations.  This was seen as evidence that the benefits
of the merger were having a quicker-than-expected impact on the company's
performance.  The market received this news very well and Novartis' share price
rose by 29% over the second quarter.  Both Zeneca and Glaxo-Wellcome continued
to prosper, also based on optimism for prospective sales growth from new drugs.

Positive Banking Environment stocks Lloyds TSB, ABN-Amro and National Australia
Bank reported profit increases ranging from 14% to 52% during the period.  This
strong performance continued into the second three months of 1997, with Banco de
Santander posting good first quarter results and HSBC Holdings gaining 29% over
the period, assisted by the strong performance of the Hong Kong market in
general.

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. This has
taken place for a variety of reasons ranging from poor company results--as was
the case with HM Sampoerna which announced poor sales forecasts--to the domino
effect of financial crises which caused poor performance by Bangkok Bank.

The currency hedging program again added value over the period.  At the end of
July hedges were in place against the British Pound, the Deutschemark, the Swiss
Franc and the Dutch Guilder.  Approximately 17% of the portfolio is currently
hedged.

ECONOMIC & MARKET REVIEW

With the notable exception of the developing markets in the Pacific Basin,
equity markets worldwide have thus far done well during 1997.  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-highs over the last six
months.

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.  The initial actions of the
country's new Labour government have been a source of encouragement to the
market, although the administration's fiscal and monetary policies will be
analyzed very closely.

The weakness of the Deutschemark stimulated a recovery in Germany's
export-oriented manufacturing sector in the early part of the year and during
the second quarter, foreign orders have increased at a steady pace.  Their
domestic economy remains in the doldrums, however, and unemployment remains at,
or close to record levels.

Far Eastern markets performed poorly during the first three months due to fears
about the upward direction of U.S. interest rates and continued net outflows by
foreign investors.  During the second quarter in Malaysia, concern about strong
consumer spending, a rising level of imports, high labor costs and a possible
oversupply of property all contributed to drive the market downwards.  The
ongoing financial crisis in Thailand resulted in a 25% decline in the market
during the latter part of the period.  

The Japanese market, on the other hand, rebounded strongly, gaining 22% during
the second quarter.  Despite continued speculation that interest rates are set
to rise, coupled with a mixed picture on the domestic economy's future growth
prospects, foreigners continue to increase their investments in Japan.  Little
attention is being paid to the current paltry state of the financial sector
where banks are continuing to struggle under the burden of their bad debts which
are estimated, by the most optimistic of forecasters, to absorb profits for the
next 3.3 years.

OUTLOOK:

Our outlook for the remainder of the year remains the same.  The low-growth,
low-inflationary environment, which prevails globally, will continue to provide
a favorable backdrop for equity investments.  Nevertheless the upward movement
of most markets has driven up valuations relative to earnings growth and this
fact remains uppermost in our minds.  These gains have pushed many multiples to
very high levels and are occurring against an interest rate background which, if
anything, is deteriorating.  Many stock prices, especially the blue chips, and
even more so, some financials have increased beyond their fundamental values.

Based on relative valuations levels, this has led us to move from some of the
more highly priced U.K. and continental European stocks, switching the proceeds
into a number of selected Japanese holdings where valuation levels are looking
increasingly reasonable.

                                       3
<PAGE>
Overall, global economic conditions remain on the positive side, with few
general signs of real inflationary pressures.  The only exceptions to this are
the U.K. where there have been some interest rate rises and where the currency
is becoming less competitive, and some of the smaller Far Eastern countries in
recent months. The debate on the introduction of the Euro in 1999 and the likely
list of initial participants continues to be a major focus in Europe but the
general consensus is that European monetary union will go ahead on schedule.

Thank you for your continued confidence and investment in the Fund.

FOOTNOTE TO LINE GRAPH AND AVERAGE ANNUAL TOTAL RETURNS  
Total return data for the Fund for periods prior to October 11, 1996, reflect
the performance of the pool of assets transferred on that date into the
Berger/BIAM International Portfolio in which all of the Fund's assets are
invested, adjusted at that time for any increase in expenses anticipated in
operating the Fund, including the Fund's pro rata share of the aggregate annual
operating expenses, net of fee waivers, of the Portfolio.  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.  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.

BERGER/BIAM INTERNATIONAL CORE FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
JULY 31, 1997


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 Fund and the Trust are registered under the
Investment Company Act of 1940, as amended, as open-end management investment
companies.  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 Fund
commenced investment operations on October 11, 1996 ("Commencement of Investment
Operations").

     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 (75% at July 31,
1997).  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 portfolio 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 paid by
BBOI Worldwide LLC, the advisor of the Portfolio (the "Advisor").  The Advisor
has delegated the daily portfolio 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 Associates, Inc. ("Berger") also owns 50% of the Advisor.

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
     The price of the Fund's shares is based on the net asset value of the Fund,
which is determined 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
that the Exchange is open.  The per share net asset value of the Fund is
determined by dividing the total value of its assets, less liabilities, by the
total number of shares outstanding.  Since the Fund will invest all of its
investable assets in the Portfolio, the value of the Fund'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 Statement which accompany these Financial
Statements for the Fund.

INCOME AND EXPENSES
     As an investor in the Portfolio, the Fund 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 the Fund and other
investors in the Portfolio.

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.

                                       9
<PAGE>
DIVIDENDS AND DISTRIBUTIONS
     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 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 treatments for
net operating losses and expiring capital loss carryforwards.  Accordingly,
these permanent differences in the character of income and distributions between
financial statements and tax basis will be reclassified to paid-in-capital.  At
July 31, 1997, no such differences existed.

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 communication 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.    

     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 that it requires.  In addition, IFTC has been appointed to serve as
the Fund's custodian, transfer agent and dividend disbursing agent.

     Certain officers and trustees of the Trust are officers and directors of
the Advisor or Sub-Advisor.  Trustees who are not affiliated with the
Portfolio's Advisor or Sub-Advisor are compensated for their services according
to a fee schedule, allocated among the Berger Funds and Berger/BIAM Portfolio,
which includes an annual fee component and a per meeting component.  Such fees
are allocated directly to the Portfolio and indirectly to the Fund.

3.   CHANGE OF FISCAL YEAR

     Effective April 11, 1997, the trustees of the Trust changed the fiscal year
end of the Fund from July 31 to September 30.

BERGER/BIAM INTERNATIONAL PORTFOLIO
Notes to Financial Statements (Unaudited)
July 31, 1997


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, the investment advisor of the Portfolio ("BBOI").  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.  
          
     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 will be 
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.  All 
assets and liabilities initially expressed in terms of non-U.S. dollar 
currencies are translated into U.S. dollars at the prevailing market rates as 
quoted by one or more banks or dealers shortly before the close of the 
Exchange.  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.

                                      19
<PAGE>
FEDERAL INCOME TAXES
     The Portfolio intends to be treated as 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.

SECURITY GAINS AND LOSSES
     Gains and losses are computed on the identified cost basis for both 
financial statement and Federal income tax purposes for all securities.  
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.  Interest income is recorded on the accrual 
basis and includes amortization of discounts.

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.

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.

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 portfolio 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 Operations 
through July 31, 1997, except for the amount payable on the Citizens NH 
converted assets.

                                      20
<PAGE>
     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 
Operations through July 31, 1997, the Fund received $57,888 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 
the Advisor or BIAM.  Trustees who are not affiliated with the Advisor or 
BIAM are compensated for their services according to a fee schedule, 
allocated among the Berger Funds 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 operations through 
July 31, 1997, totaled $36,109.

3.   INVESTMENT TRANSACTIONS

PURCHASES AND SALES
     Purchases and sales of investment securities (excluding short-term 
securities) during the period from Commencement of Investment Operations to 
July 31, 1997 were as follows:

                   Purchase of                   Sales of
               Investment Securities       Investment Securities

                  $    89,505,618             $    7,790,854

     There were no purchases or sales of long-term U.S. Government securities
during the period.

     At July 31, 1997, the composition of unrealized appreciation (the excess of
value over tax cost) and unrealized depreciation (the excess of tax cost over
value) for securities held was as follows:

                Appreciation        Depreciation          Net 
               --------------      --------------    --------------
               $    11,187,925     $    2,387,401    $    8,800,524

4.   CHANGE OF FISCAL YEAR

     Effective April 11, 1997, the trustees of the Trust changed the fiscal year
end of the Portfolio from July 31 to September 30.
