Portfolio Manager's Commentary                                 Patrick S. Adams

Performance

This was a significant transition year for the Berger IPT -- 100 Fund (the
"Fund"). Pat Adams took over the helm of your Fund in early February and
undertook a significant restructuring. Unfortunately, the market environment was
at cross-purposes with our investment approach for fully half of the year. As a
result, the Fund's annual total return of 13.76%/1/ for the year ended December
31, 1997 lagged the Standard & Poor's (S&P) 500/2/ annual total return of 33.36%
for the same period.

Year in Review

We began repositioning the Fund's portfolio in February, doing what we call
"weeding the garden." We pulled older stocks that may have reached their full
potential or that had not been performing up to expectations and made growing
room for newer names. We repositioned the Fund slowly and carefully and
completed most of the moves we felt were necessary by the end of June. The
second quarter saw a strong rotation in the market, largely in response to the
Federal Reserve Board's interest rate increase. In a "flight to quality,"
skittish investors sought refuge in large, liquid "blue chip" or "index" stocks,
which, while very expensive, are viewed by many as "safe" investments in a
volatile market. This environment was inhospitable to our investment style,
which emphasizes reasonably priced, high-quality companies with a history of
strong, consistent earnings growth.

The difference between second and third quarter Fund performance was like night
and day. After disappointing results in the second quarter, we outperformed
broad market averages and were very competitive in our peer group of funds in
the third quarter. This was the result of two factors. First, our restructuring
efforts began to bear fruit, and, second, the market broadened out and investors
rediscovered the merits of the types of stocks held in our Fund.

In the fourth quarter the market caught the "Asian flu", and so did the Fund. We
significantly lagged the S&P 500 this quarter -- 4.83% total return for the Fund
compared to 2.87% for the index. Southeast Asia's economic woes, which
potentially may result in a decline in Gross Domestic Product growth worldwide,
spooked a U.S. stock market that had experienced more than two years of
unprecedented growth. As we saw in the second quarter, the market again turned
defensive and rushed to large cap stocks. Once again, that hurt your Fund
because we do not invest in many of the very expensive, big name, defensive
stocks heavily favored by the market this quarter.

In addition, the technology sector, in which we are heavily weighted, was
negatively impacted by the Asian downturn. Investors believe, somewhat unfairly,
that technology companies, especially manufacturers, have a high exposure to
Asian countries. Yet, personal computer sales in Asia (excluding China and
Japan) account for less than 10% of worldwide totals.

We don't believe that the performance of technology stocks in the fourth quarter
indicates problems in the industry or in many companies. Although slightly
slower growth rates in computer sales are likely in the future, we think
technology stocks will come back strong in 1998, particularly if fourth quarter
1997 and first quarter 1998 earnings reports reveal continued strong
fundamentals. For this reason, we used the fourth quarter downturn in technology
as a buying opportunity and increased our technology holdings from 21.4% of
total Fund assets on September 30 to 28.9% on December 31.

We also took advantage of lower prices to add to our energy holdings, increasing
this small sector weighting from 1.5% on September 30 to 5.9% at year-end. We
took some profits in healthcare because we believe this sector looks
overextended.

Looking Ahead

We are optimistic about economic prospects for 1998. As investors put Asian
problems in perspective and recognize the U.S. economy's strengths (strong
employment, low inflation, steady growth rates), we believe the markets will
broaden out once again. We believe this will provide a far more favorable
backdrop for our growth at a reasonable price investment style.

BERGER IPT-GROWTH AND INCOME FUND



Portfolio Manager's Commentary               Sheila Ohlsson and Patrick S. Adams

Performance

The past year was a very challenging one for stock market investors. The market
began 1997 with incredible strength, led by large cap, big name "index" stocks
such as Coke, Gillette and Procter & Gamble. After broadening out during the
second and third quarters, the market ended the year in extreme volatility as
concerns related to the turmoil in Southeast Asia began to adversely affect the
U.S. stock market, and, once again, drove investors to index stocks that they
consider to be safer havens in market storms. Because index stocks often are
quite pricey, they usually do not fit our "growth at a reasonable price"
investment style. As a result, the 24.99%/1/ annual total return of the Berger
IPT-Growth & Income Fund (the "Fund") lagged the 33.36% return on the Standard &
Poor's (S&P) 500/2/.

Year in Review

Technology stocks were particularly hard hit by aftershocks from the Asian
crisis because these types of companies are thought to have the greatest
exposure to this region, both in terms of sales and manufacturing. Earlier in
the year, the Fund had as much as 20% of its total assets invested in the
technology sector. As of December 31, we had reduced our holdings to 11.2% of
total assets. This said, however, we also continue to believe that technology is
driving the U.S. and world economies, and that, longer term, this sector will
prove to be fertile ground for new investment opportunities. The early months of
1998 should give investors a better idea of what to expect in the future.

Oil services remained an important industry for the Fund in 1997, with
approximately 8.7% of total Fund assets invested in this group. Investor
concerns about exploration and production budgets for 1998, however,
precipitated a significant correction that negatively impacted Fund performance.
We believe that these concerns are overblown, that the fundamentals of the
sector are intact and that investors will return to the group in 1998. In fact,
stocks in this group are selling at very reasonable valuations relative to what
we believe will be solid earnings growth in 1998 and 1999.

Healthcare and consumer stocks continue to be defensive sectors for the Fund and
have little or no Asian exposure. During what we anticipate to be a choppy
market in early 1998, we plan to allocate a greater portion of Fund assets to
these groups. Financial stocks continue to be the Fund's largest sector
allocation, with 23.7% of total assets invested in this group. A potential
slowdown in U.S. economic growth, caused by problems in Asia, could actually
benefit interest-rate sensitive financial stocks because a slowdown would
greatly reduce the likelihood that the Federal Reserve Board would raise
interest rates.

Looking Ahead

In terms of the Asian downturn, we see three potential implications for U.S.
companies in the near term:

1.   For companies that manufacture goods in Asia, it's a net positive, given
     that local currency devaluations lead to cheaper U.S. dollar costs. 

2.   For companies that sell to Asia, it's a net negative as revenue growth
     generated in that region will slow down, at least for a period of time.

3.   Cheaper Asian exports will keep downward pressure on prices of competitive,
     U.S. manufactured goods.

                                       8

We believe that fallout from the Asian situation will likely result in slower
near-term U.S. economic growth. Slower growth should, as we noted above, make it
less likely that the Fed will raise interest rates. Slower growth also can be a
negative, however, because the pricing environment may not be quite as robust as
it has been.

Going forward, we will continue to look for the highest quality companies
selling at reasonable valuations. Overall, we feel 1998 will be a challenging
market environment and that it will be even more imperative to be exceptionally
discriminating in our stock selection.

BERGER IPT-SMALL COMPANY GROWTH FUND


Portfolio Manager's Commentary                                     Bill Keithler

Performance

Against the backdrop of one of the most turbulent stock markets in recent
memory, the Fund's annual total return was 21.21%/1/ compared to 22.36% for the
Russell 2000/2/. The Russell 2000 Growth index/3/, which is a more accurate
comparison for the Fund, was up 12.86% for the 12-month period ending December
31, 1997.

Year in Review

The year began with the Dow Jones Industrial Average hitting new highs, while
the prices of most smaller capitalization growth stocks were declining. In the
first quarter, the small cap Russell 2000 index was down 5% and the large cap
Dow and Standard & Poor's (S&P) 500 indices were up. After bottoming in late
April, small cap stocks exploded upward in a rally that extended through late
September. Most small cap out performance occurred in May, when this Fund was up
15.45% during that month. Everything changed during the fourth quarter; the
market generally, and small caps in particular, turned down on concerns about an
economic crises in Asia. Small cap stocks quickly fell out of favor as investors
shifted to high quality, "safer" investments such as large cap stocks, U.S.
Treasury bonds and companies whose earnings prospects are less (or not)
dependent on foreign business. Technology companies, which typically have
significant business in Asia, became the market's prime target. 

Although it has been difficult to find safe havens among smaller cap growth
stocks in this market, some stocks/sectors performed relatively well for the
Fund, including Allied Waste Industries (Environmental Services), CCA Prison
Realty (Real Estate Services), Incyte Pharmaceuticals (Pharmaceuticals-
Biomedical), Boron LePore and Associates (Healthcare Services), Lycos Inc. (New
Age Media) and Rexall-Sundown (Consumer Products). Business service stocks
generally did well, including advertising-related industries (radio and
outdoor), computer services, consulting and education. These companies are U.S.-
based and relatively insensitive to the economic cycle. Poor performing sectors
included technology, especially semiconductor capital equipment companies, and
energy services. 

Technology holdings were relatively unchanged during the third and fourth
quarters, although the composition of the holdings changed with the expansion of
telecommunication companies, at the expense of semiconductor and other
electronics companies. In September, we had 30.6% of total Fund assets invested
in technology sectors; by year-end, the percentage was 29.1%. Also, we boosted
our healthcare and business services exposure because these sectors exhibit many
of the characteristics favored by the current market environment and contain
many stocks with attractive valuations. We selectively took profits in the
consumer sector, particularly among retailers, and to a lesser extent, in energy
services.

Looking Ahead

Our outlook for 1998 is somewhat cautious. Although there is evidence of factors
that have historically been favorable to the performance of small cap stocks, we
feel these stocks will remain under pressure a while longer. Earnings reports
are starting to come out and a spate of companies are pre-announcing earnings
disappointments, which usually cause stocks to be weak. Many of these shortfalls
are being blamed on weak demand in Asia. It remains to be seen if Asia is,
indeed, the source of the problem and how much more the situation could worsen.
Specifically, we need to see if Asia's economic weakness spreads to other
economies, including the U.S., due to weak demand and heightened competition
from lower cost importers. Until the magnitude of the crisis becomes clearer, we
believe the market will continue to be risk averse and to favor bonds, larger
companies and low-valued stocks.

In addition, there is concern about the prospect of a deflationary environment
in which prices actually fall. The Asian crisis has heightened focus on this
prospect because of the dramatically lower costs Asian countries now enjoy
relative to the U.S. Even before the crisis, however, there were signs of
deflation detectable in the general lack of pricing power at both the wholesale
and retail level. While deflation is constructive for bond prices and, hence,
interest rates, companies find it very difficult to continue to grow earnings
when prices are falling. In such an environment stock prices don't usually
advance.

A full-scale deflation, such as occurred in the 1930s, in our opinion, is a
worst case scenario and highly unlikely. We believe that Asian events will have
a negative impact on the U.S. economy, but not a catastrophic one. Once the
magnitude of the Asian situation is determined, the market can return its focus
to individual company fundamentals, which, in many cases, remain outstanding.
Many small cap stocks have been sold down to levels that are near historic lows
and we believe could present excellent buying opportunities. It is always
difficult to buy into a panic, but if one is correct in their assessment of the
investment merits of a purchased stock, it quite often turns out to be a
rewarding decision.

/1/ Performance figures are based on historical results, including reinvestment
    of dividends and capital gains, 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 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.

/3/ The Russell 2000 Growth Index is an unmanaged index composed of those
    Russell 2000 securities with a greater-than-average growth orientation.
    Securities in this index generally have higher price-to-book and price-
    earnings ratios than those in the Russell 2000 Value Index.

BERGER/BIAM IPT-INTERNATIONAL FUND


Portfolio Manager's Commentary     Bank of Ireland Asset Management (U.S.) Ltd. 

Performance

The Berger/BIAM IPT-International Fund (the "Fund") had a total return of -
2.10%/1/ for the period ended December 31, 1997 compared to 2.06% for the MSCI
EAFE Index/2/. The Fund's performance was aided primarily by holdings in
Positive Banking, Healthcare Needs and Leading Consumer Franchises. Laggards,
not surprisingly, were those themes and companies with exposure to Southeast
Asia and the Pacific Rim.

The prevailing low interest rate environment worldwide has been one of the main
linchpins of equity market strength. Accordingly, on a thematic basis, Positive
Banking Environment added significant value to the portfolio in 1997. U.K.-
quoted Barclays Bank performed very well during the second half of the year and
was the biggest contributor to the theme's overall performance. Barclays' upward
move was prompted by the release in August of larger-than-expected pre-tax
profits and the simultaneous announcement of an expanded share buy-back program.
Banco de Santander also benefited from good-earnings news during the first half
of the year. Later it announced the sale of its stake in the U.S. bank, First
Union, and said that it plans to use the proceeds to strengthen its balance
sheet following an ambitious acquisition drive in Latin America.

The top performer in Healthcare Needs was Novartis, the Fund's largest holding.
In the first full year since Novartis was created by the merger of Ciba Geigy
and Sandoz, it became apparent that the benefits of the alliance were having a
much quicker-than-anticipated impact on performance. Glaxo Wellcome also was an
impressive performer during 1997. Even though its best-selling drug, Zantac,
came off patent, new drugs to treat asthma, AIDS and migraine, among others, are
expected to increase Glaxo's sales by 50% per annum over the next few years.
Additionally, the company's research and development pipeline is well primed.

Consumer oriented stocks in Leading Consumer Franchises did well during the
year. The largest holding in this theme, B.A.T. Industries, hit the news in the
fourth quarter when it announced a merger between its financial services
divisions and Zurich Insurance Group. This ended the company's year-long search
for a means to release value for shareholders. The proposed merger will create
an insurance giant with a market capitalization of approximately $37.3 billion,
which would make the new entity the second largest insurer in Europe. The merger
of Guinness and Grand Metropolitan was completed in December and the new
company, which is called Diageo, is now the world's largest beverage company.

On the negative side, themes with companies quoted in, or with earnings exposure
to, Southeast Asia and the Pacific Basin suffered during the year, including
Infrastructural Development and Expanding Financial Services in Developing
Markets. Another poor performer was Increased Consumer Spending in the Pacific
Basin, which saw companies such as Indonesia-quoted HM Sampoerna and 
Philippines-quoted San Miguel hurt by the regional crisis.

Year In Review

Global equity markets, with the notable exception of Southeast Asia and the Far
East, performed very strongly during 1997. The almost universal phenomena of
steady economic growth and low inflation, which, for the last three years have
been the springboards for rising share prices, underpinned the strong stock
market performances.

Europe generally did well during the year on the back of lower interest rates,
increased signs of economic recovery and evidence that management was paying
greater attention to shareholders' interests. Despite fallout from the Asian
crisis, European equity markets rallied to finish 1997 in a display of strength.
The Swiss bourse was the best performing Continental European market over the
year, and the Dutch and German exchanges also had good showings.

In the U.K., strong corporate earnings, particularly from the financial services
sector and the expectation of corporate restructuring, provided the foundation
for a solid year in the equity market. The main factor driving the market
upwards over the year was a sharp fall in long-term interest rates. The U.K.
economy is showing some signs of slowing down, with an apparent loss of momentum
in industrial production and consumer spending.

The seven worst performing equity markets during 1997 were located in Asia,
which experienced a succession of economic and political crises in the second
half of the year. The Nikkei Stock Index/3/ managed to gain 22% during the
second quarter in spite of disarray in the country's financial sector and the
poor state of the domestic economy. However, the gain was short lived. During
the second half of the year, Japan suffered from effects of the currency and
political crises that started in Thailand in May and continued across Southeast
Asia and into the Far East during the remainder of the year. The structural
problems in Asia were exacerbated by the head-in-the-sand approach of political
leaders in the region.


Looking Ahead

While Asia is trying to shake off the hangover of its property binge, we are
unlikely to allocate any further funds to the region unless, and until, we see
an overwhelming and decisive policy response by the various governments in the
region. We believe this action is necessary to make the currencies bottom out
and cause a turnaround in current account deficits. Until then, over capacity in
sectors such as airlines, chemicals, steel, automobiles, cement and electronics,
as well as excessive leverage in the region's financial systems, is likely to
continue to undermine share prices. Asia's rehabilitation will be slow because
its governments have been reluctant to admit the extent of their problems and
this recalcitrance has damaged, rather than restored, confidence in the region.

For seven years, Japanese authorities have been attempting to tiptoe through the
minefield that is their domestic financial sector. Problems throughout Asia now
make reform in Japan even more urgent, and markets will be waiting for the
Japanese to tackle their problems head on. To do this, the authorities must make
a major move to reflate the economy from within because the easy route, i.e.,
external stimulation via the weak yen, has already failed.

On a macro-economic level, Japan has, thus far, failed to deal with the problems
it faces. Selective Japanese companies, however, that have bitten the bullet in
recent years and their restructured operations have delivered strong earnings
growth, despite worsening GDP forecasts for the country as a whole.
Consequently, during the second half of 1997 we invested in a number of Japanese
companies which, on a relative valuation basis, look attractive compared to

In Europe and the U.K., the push for European Monetary Union will continue to
play a strong role in equity market performance in 1998. As a result, merger and
acquisition activity is expected to remain strong. Financial stocks are most
likely to benefit from the moves but pharmaceuticals and telecommunications also
are likely to stay high on the list of good performing stocks.


/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 Morgan Stanley Capital International EAFE Index represents major overseas
   stock markets. It is an unmanaged index. One cannot invest directly in an
   index.

/3/The Nikkei Stock Index is a price-weighted index of 225 top-rated Japanese
   companies listed on the Tokyo Stock Exchange.

Berger Institutional Products Trust
Notes to Financial Statements
December 31, 1997

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization

     Berger Institutional Products Trust (the "Trust"), a Delaware business
trust, was established on October 17, 1995 as a diversified open-end management
investment company. The Trust is authorized to issue an unlimited number of
shares of beneficial interest in series or portfolios. Currently, the series
comprising Berger IPT-100 Fund ("IPT-100"), Berger IPT-Growth and Income Fund
("IPT-G&I"), Berger IPT-Small Company Growth Fund ("IPT-SCG") and Berger/BIAM
IPT-International Fund ("IPT-International"), (individually the "Fund" and
collectively the "Funds") are the only portfolios established under the Trust,
although others may be added in the future. The Funds commenced investment
operations on May 1, 1996, except for IPT-International which commenced
investment operations on May 1, 1997.

The Trust is registered under the Investment Company Act of 1940 and its shares
are registered under the Securities Act of 1933 (the "Acts"). 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 Trust's shares are not offered directly to the public, but are sold
exclusively to insurance companies ("Participating Insurance Companies") as a
pooled funding vehicle for variable annuity and variable life insurance
contracts issued by separate accounts of Participating Insurance Companies and
to qualified plans. All costs incurred in organizing the Trust were paid by
Berger Associates, Inc. ("Berger"), the investment advisor to IPT-100, IPT-G&I
and IPT-SCG and by BBOI Worldwide LLC ("BBOI"), the investment advisor to IPT-
International.

     On April 15, 1996, Berger purchased 25,000 shares of each of IPT-100, IPT-
G&I and IPT-SCG at a net asset value of $10.00 per share. On May 1, 1997, Berger
purchased a variable annuity contract through which it indirectly owns 200,000
shares of the IPT-International for $2 million. At December 31, 1997, Berger,
directly or indirectly, owned 24%, 23%, 11% and 72% of the outstanding shares of
IPT-100, IPT-G&I, IPT-SCG and IPT-International, respectively.

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.

     The Funds are permitted to hold certain types of futures, forwards and
options (except for IPT-International, which may only hold forward foreign
currency exchange contracts) for the purpose of hedging the fund 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 investments and the assets being hedged,
or unexpected price movements, could render a Fund's 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, if any, are included in Net Realized Gains (Losses) from Securities
and Foreign Currency Transactions in the Statements of Operations.

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 that are traded on 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. Securities 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
Funds 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.

                                       33
<PAGE>
 
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 the 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.

     Dividends received by shareholders of the Funds which are derived from
foreign source income and foreign taxes paid by the Funds are to be treated, to
the extent allowable under the Code, as if received and paid by the shareholders
of the Funds.

Foreign Currency Translation

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

Investment Transactions and Investment Income

     Investment transactions are accounted for on the date investments are
purchased or sold. Dividend income is recorded on the ex-dividend date, except
if the ex-dividend date has passed, such dividends from foreign securities are
recorded 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.

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
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

     Berger serves as the investment advisor to IPT-100, IPT-G&I and IPT-SCG and
BBOI serves as the investment advisor to IPT-International. Berger and Bank of
Ireland Asset Management (U.S.) Limited ("BIAM") each own 50% of BBOI. BBOI has
delegated the day-to-day portfolio management of IPT-International to BIAM. As
compensation for their services to the Funds, Berger and BBOI receive an
investment advisory fee, which is accrued daily at the applicable rate and paid
monthly. The fees are based on an annual rate of each Fund's average daily net
assets as follows: IPT-100 and IPT-G&I at .75 of 1% of average daily net assets;
IPT-SCG and IPT-International at .90 of 1% of average daily net assets. As sub-
advisor to IPT-International, BIAM receives a sub-advisory fee from BBOI at an
annual rate of .40 of 1% of the average daily net assets of the Fund. BIAM has
agreed to waive such sub-advisory fees for the period from May 1, 1997 to
October 15, 2000. Berger and BBOI have agreed to waive their advisory fees and
reimburse expenses to the Funds to the extent that normal operating expenses in
any fiscal year (including the advisory fee but excluding brokerage commissions,
interest, taxes and extraordinary expenses) exceed 1.00% of the average daily
net assets of both IPT-100 and IPT-G&I, 1.15% of the average daily net assets of
IPT-SCG and 1.20% of the average daily net assets of IPT-International.

     IPT-100, IPT-G&I and IPT-SCG have entered into administrative services
agreements with Berger. The administrative services agreements provide for an
annual fee of .01 of 1% of the average daily net assets of each Fund accrued
daily and paid monthly. IPT-International has entered into an administrative
services agreement with BBOI. The administrative services agreement provides for
a fee at an annual rate of .01 of 1% of the average daily net assets of the Fund
accrued daily and paid monthly. BBOI has delegated the day-to-day administrative
duties to Berger. Berger receives a sub-administration fee from BBOI at an
annual rate of .20 of 1% of the average daily net assets of IPT-International.
Berger voluntarily waived such sub-administration fee for the period from May 1,
1997 to December 31, 1997.

                                       34
<PAGE>
 
     The Trust has entered into a recordkeeping and pricing agreement with
Investors Fiduciary Trust Company ("IFTC"), who also serves as each Fund's
custodian and transfer agent. The recordkeeping and pricing agreement provides
for the monthly payment of a base fee per Fund plus a fee computed as a
percentage of average daily net assets on a total relationship basis. 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 the Fund held by IFTC as custodian or 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 December
31, 1997, the IPT-100 earned $28 for such credits. The IPT-G&I, IPT-SCG and IPT-
International earned no credits during such period.

Certain officers and directors of Berger and BBOI are also officers and trustees
of the Trust. Trustees who are not affiliated with Berger and BBOI received
trustees' fees totaling $402, $397, $463 and $549 from IPT-100, IPT-G&I IPT-SCG,
and IPT-International, respectively, for the year or period ended December 31,
1997.

D. 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 December 31, 1997, 3.16% and 3.72% qualified for the
dividends received deduction available to the corporate shareholders of IPT-100
and IPT-G&I Funds, respectively.

     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 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 have been reclassified to paid-in-capital.
During the year or period ended December 31, 1997, the following
reclassifications were made:

                           IPT-SCG              IPT International
- --------------------------------------------------------------------------------
Paid in Capital             (154)               ---

Undistributed Net
Investment Income            154                27,422

Undistributed Net
Realized Gain                ---               (27,422)


     At December 31, 1997, the Funds had capital loss carryovers, which may be
used to offset future realized capital gains for Federal income tax purposes.
Additionally, IPT-SCG incurred and elected to defer post-October 31 net capital
losses of $43,056 to the year ended December 31, 1998. IPT-International
incurred and elected to defer post-October 31 net capital losses and currency
losses amounting to $31,115 to the year ended December 31, 1998.

     At December 31, 1997, IPT-SCG Fund had $16,903 and $39,861 in capital loss
carryovers which expire in the years 2004 and 2005, respectively.

     Net capital loss carryovers utilized in 1997 by IPT-100 and IPT-G&I Funds
amounted to $8,758 and $5,025, respectively.

                       Report of Independent Accountants


To the Board of Trustees and Shareholders of
Berger Institutional Products 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 each of the portfolios constituting
Berger Institutional Products Trust (the "Trust") at December 31, 1997, the
results of each of their operations, the changes in each of their net assets 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 December 31, 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.
