                                                                   June 20, 2000
Dear Shareholder:

   For the six  months  ended  April  30,  2000,  Warburg  Pincus  Institutional
Fund--International Equity Portfolio had a return of 16.94%, vs. a gain of 8.66%
for the Morgan Stanley  Capital  International  All Country World  Excluding the
U.S. Index.* The Portfolio's  one-year return through April 30, 2000 was 41.13%.
Its five-year and  since-inception  (on September 1, 1992) average  annual total
returns through April 30, 2000 were 13.12% and 14.47%, respectively.

   International  stock markets had generally good results for the period.  Most
European markets advanced,  some  impressively,  buoyed by an improving economic
outlook across the region. The group's returns were more modest for dollar-based
investors,  however, as the euro and most other European currencies weakened vs.
the dollar  during the period.  Within Asia,  Japan had a  respectable  showing,
though  profit-taking  roiled the market late in the period, with technology and
Internet-related names under especially heavy selling pressure.  Asia's emerging
markets had mostly  solid,  though  volatile,  gains,  as did  emerging  markets
generally.  Other  winners  for the period  included  Canada,  helped by firming
commodity prices.

   The Portfolio had a good showing for the six months,  both in absolute  terms
and  compared  to that of its  benchmark.  The  Portfolio  benefited  from  good
performances  from a number  of its  holdings,  especially  its  technology  and
telecommunications names. Also contributing positively to the Portfolio's return
was its exposure to certain  strong-performing  emerging markets (e.g.,  Turkey,
Hungary and Taiwan) and its significant weighting in Canada.

   We made few noteworthy changes to the Portfolio during the period in terms of
overall  sector   strategy.   We  remained   well-diversified,   and  maintained
significant  exposure  to  both  rapid-growth  and  economically  sensitive,  or
cyclical,  segments of foreign markets.  Such a "barbell"  approach can serve to
limit volatility, given the seismic short-term shifts in investor sentiment that
can favor one group at the expense of the other.  In  addition,  we believe that
having some economically  sensitive investments makes sense when all three major
regions of the world are projected to grow.

   In terms of regional/country allocation, the most notable move we made was to
reduce our exposure to Japan. We entered the period with a sizable overweighting
here, but assumed a roughly neutral position as the period progressed,  based on
valuation considerations and on our desire to take advantage of opportunities we
saw  developing  elsewhere.  That  aside,  we believe  that a number of Japanese
stocks stand to benefit  from  ongoing  reform--at  both the  macroeconomic  and
corporate  levels--and from trends such as Japan's  continued  embrace of equity
investing. We continued to

generally see the most  compelling  growth  stories  among  Japan's  technology,
communications and financial-services  companies.  Elsewhere of note in Asia, we
raised our weighting in South Korea,  taking  advantage of market  volatility to
add a few technology stocks we viewed as good values.

   Our  increased  weighting  in  Europe  was  largely  via the  U.K.,  based on
company-specific  factors  and on our belief  that the  country's  interest-rate
backdrop will be more  supportive  going  forward.  We also modestly  raised our
weightings in Italy and Sweden. Overall, we believe that Europe's equity markets
will continue to be supported over the longer term by an expanding  economy,  as
well as by a strong  deregulation and  privatization  trend.  Across the region,
monopolies  are  being  transformed  into  competitive   companies,   benefiting
shareholders and consumers alike.  Furthermore,  the  liberalization  of certain
industries  (e.g.  telecommunications  and  utilities),  combined  with a single
currency  environment,  will prompt merger and acquisition  activity,  which has
surged dramatically over the past year and shows little sign of slowing.

   Turning to the  Americas,  we had a meaningful  weighting  in Canada,  one we
increased  during the period,  adding several  technology and  natural-resources
stocks  we deemed to be  attractive.  Our  exposure  to Latin  America  remained
minimal,  as we continued to find  more-compelling  stocks elsewhere,  though we
will continue to monitor the area for buying opportunities.

   Looking  ahead to the rest of 2000  and  beyond,  we see  ample  grounds  for
optimism  regarding   international-equity   markets,   notwithstanding   recent
volatility in stocks  generally.  Trends that stand to support  foreign  markets
broadly include the potential for continued,  and synchronized,  global economic
growth as well as improving  financial  conditions within emerging markets (many
Asian  emerging  economies,  for example,  have recently  shifted from debtor to
creditor status).  Set within this environment,  we will continue our efforts to
identify markets and companies with the brightest long-term prospects.

                                                                   June 20, 2000
Dear Shareholder:

   For the six  months  ended  April  30,  2000,  Warburg  Pincus  Institutional
Fund--Emerging  Markets Portfolio had a return of 26.03%, vs. a return of 13.87%
for the Morgan Stanley Capital  International  Emerging Markets Free Index.* The
Portfolio's's   one-year   return  through  April  30,  2000  was  53.57%.   Its
since-inception (on September 30, 1996) average annual returns through April 30,
2000 was 3.49%.

   The period was a positive  one for the  majority of emerging  stock  markets,
though results varied by region.  The best  performances  generally  belonged to
Eastern/Central  European  markets,  supported  by growing  optimism  over their
economic and financial  prospects.  Most Asian  markets also had good  showings,
though  these  were  volatile  late  in  the  period,   buffeted  by  rounds  of
profit-taking.  Within Latin America,  Brazil and Mexico,  the region's dominant
markets, also advanced. With regard to sector attribution, technology, media and
telecommunications  ("TMT") stocks paced the rally in most markets. However, TMT
stocks finished the period on a very difficult note, reflecting contagion from a
downturn in the Nasdaq, the technology-biased U.S. index.

   Against this  backdrop,  the Portfolio  had a good showing,  both in absolute
terms and compared to that of its benchmark. The Portfolio saw good performances
from a number of its holdings,  especially  its  technology  and  communications
stocks.  In terms of  regional  attribution,  factors  that aided the  Portfolio
included its overweighting in Turkey, the best-performing  emerging stock market
for the six months.

   We made a few  noteworthy  changes to the  Portfolio's  regional  and country
exposure  during the period.  Within Asia,  changes  worthy of mention  included
increasing   our   exposure   to   Taiwan.    Our   focus   here   remained   on
hardware/electronics  companies  well-positioned  to take  advantage of a strong
global outsourcing trend. Whereas hardware sales within many emerging markets is
domestically  driven,  Taiwan  is  a  substantial  exporter.  As  such,  certain
companies  here stand to continue to benefit from growing  worldwide  demand for
Internet-related and other hardware products.  These companies,  moreover, offer
valuations that are compelling vs. those on their developed-market counterparts.
One country  weighting we reduced in Asia was South Korea. This partly reflected
our  concerns  over  the  country's   technology  sector,   which  tends  to  be
particularly vulnerable to Nasdaq volatility.

SEMIANNUAL INVESTMENT ADVISER'S REPORT -- APRIL 30, 2000 (CONT'D)
--------------------------------------------------------------------------------

   Within  Eastern/Central  Europe,  we maintained an  overweighting  in Turkey,
reflecting  our optimism over the  country's  ongoing  IMF-sanctioned  financial
reforms  (though  we  scaled  back this  position  late in the  period  based on
valuation  considerations).  We also  established  a modest  position in Russia,
where we believe the macroeconomic and political environment is improving,  some
near-term financial-market uncertainties notwithstanding. One weighting we pared
during the period was Hungary, an adjustment based on valuation concerns.

   Our Latin America  exposure  remained  concentrated on Mexico and Brazil.  We
raised  our  exposure  to the latter at the  expense  of the  former  during the
period, based on relative-valuation  considerations, and on our view that Brazil
could  see  some   better-than-expected   developments   on  the  inflation  and
interest-rate  front.  Elsewhere in the region, we established a modest position
in Chile,  whose  macroeconomic  backdrop continues to improve and where capital
controls could eventually be removed.

   Looking  ahead,  we believe that the  environment  for emerging stock markets
will remain  generally  positive,  supported by an improving  global economy and
brightening  earnings picture.  These markets will likely remain quite volatile,
however.  The recent  turmoil in  Nasdaq-type  stocks could persist for a spell,
fueling frequent shifts in sentiment regarding riskier asset classes in general.
In addition,  certain emerging markets remain vulnerable to global interest-rate
uncertainties  (though  we note  that  interest  rates  in most  emerging-market
economies are well below levels seen 18 months ago). Still, we see ample grounds
for optimism,  with numerous  emerging-market  companies  poised for revenue and
earnings  improvements.  As ever, our efforts,  within this underfollowed  asset
class, will remain devoted to identifying  countries and companies with the best
long-term growth potential.

WARBURG PINCUS INSTITUTIONAL FUND -- JAPAN GROWTH PORTFOLIO
SEMIANNUAL INVESTMENT ADVISER'S REPORT -- APRIL 30, 2000
--------------------------------------------------------------------------------
                                                                   June 20, 2000
Dear Shareholder:

   For the six  months  ended  April  30,  2000,  Warburg  Pincus  Institutional
Fund--Japan  Growth  Portfolio had a gain of 2.74%,  vs. a gain of 3.21% for the
U.S.-dollar-denominated  Tokyo Stock Exchange Index  ("Topix").* The Portfolio's
one-year  return  through  April 30, 2000 was 87.38%.  Its  since-inception  (on
October 31, 1997) average annual total return through April 30, 2000 was 53.12%.

   The modest gain made by Japan's  broad stock market for the six months belied
a period of considerable volatility.  These stocks initially surged, building on
their gains earlier in 1999, but were increasingly  buffeted by profit-taking as
2000 progressed  (indeed,  for the first time in years, there were ample profits
to  be  taken).   Certain   Internet-related  "new  economy"  names  came  under
particularly  heavy selling  pressure,  reflecting  concerns over  valuations on
these stocks amid an environment for the technology area globally.

   Against this  backdrop,  the  Portfolio  had a gain,  but was hampered by the
late-period downturn in Japan's equity market and by particular turbulence among
rapid-growth companies, which remained well-represented in the Portfolio. Recent
weakness  in  these  stocks  notwithstanding,   we  believe  that  a  number  of
aggressive-growth Japanese companies have solid long-term prospects, and certain
technology and communications  stocks will continue to figure prominently in the
Portfolio.

   We made no material  changes to the  Portfolio  during the period in terms of
basic strategy. We continued to look for companies with the potential to benefit
from strong existing business  franchises,  the adoption of new technologies and
ongoing reform (e.g., with respect to capital markets) within Japan. In terms of
industry  emphasis,  we  generally  saw the most  compelling  stocks  within the
communications,      semiconductor-equipment,      electronic-components     and
financial-services  areas,  which  continued  to  account  for  the  bulk of the
Portfolio's investments.

   We maintain a positive view on the long-term  prospects for Japan as an asset
class,   notwithstanding   the  short-term   volatility  that  the  market  will
undoubtedly  display going forward.  Our optimism is founded on several factors,
not the least of which is the  potential  for positive  surprises  regarding the
world's   second-largest   economy.   Based   on  our   contact   with   company
managements--we  visit hundreds of Japanese  companies  yearly--and on a rash of
empirical data (e.g., recent upturns in sales,  profits and capital spending) we
believe that Japan's  recovery  remains intact,  which stands to support profits
while easing risk concerns over time.

SEMIANNUAL INVESTMENT ADVISER'S REPORT -- APRIL 30, 2000 (CONT'D)
--------------------------------------------------------------------------------

   One particularly encouraging trend regarding Japan's economy is a significant
upturn in corporate  Japan's  commitment to information  technology.  This could
have a materially positive impact on productivity and the economy going forward,
given  the  supportive  role IT has  played  in the U.S.  economy  over the past
decade.

   Other  positive  agents for change in a Japan striving to right itself is the
steady  expansion of equity  investing.  This includes a surge in direct foreign
investment  (which  more than  tripled in 1999) and the rise of  venture-capital
activity  in  Japan,   trends   buttressed  by  ongoing   deregulation   and  by
opportunities afforded by merger and acquisition activity.

   There remain, of course,  concerns,  such as Japan's high debt burden. But we
believe  that the  country has good  potential  to chip away its debt over time,
aided by higher tax revenues as the economy warms and by the continued expansion
of equity financing (which can favorably "crowd out" debt).

   All  told,  we  believe  that  Japan  has  much to  offer  investors  seeking
diversification  away from the U.S.,  and who are  willing to assume  short-term
risk (e.g., the risk of heightened volatility) in pursuit of long-term gains. As
ever, we will continue to strive to add value to our  portfolios  via individual
stock selection.  Notwithstanding  recent performance,  we are encouraged by our
efforts in that regard to date,  and our efforts  will  remain  concentrated  on
identifying stocks we deem to have the best long-term appreciation potential.

WARBURG PINCUS INSTITUTIONAL FUND, INC.
NOTES TO FINANCIAL STATEMENTS
April 30, 2000 (Unaudited)
--------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES

   Warburg Pincus Institutional Fund, Inc. (the "Fund")is an open-end management
investment  company  registered  under the  Investment  Company Act of 1940,  as
amended, (the "1940 Act") and was incorporated under the laws of Maryland on May
13, 1992.  The Fund  currently  offers seven managed  investment  Funds of which
three  are  contained  in  this  report.  The  International   Equity  Portfolio
("International  Equity") is classified as a  diversified,  open-end  management
investment company and the Emerging Markets Portfolio  ("Emerging  Markets") and
the Japan Growth Portfolio  ("Japan  Growth") are classified as  non-diversified
open-end management  investment companies (each, a "Portfolio" and collectively,
the "Portfolios").

   Investment objectives for each Portfolio are as follows: International Equity
seeks long-term capital appreciation;  Emerging Markets seeks growth of capital;
and Japan Growth seeks long-term growth of capital.

   The net asset value of each Portfolio is determined  daily as of the close of
regular trading on the New York Stock Exchange. Each Portfolio's investments are
valued at market value,  which is generally  determined  using the last reported
sales price. If no sales are reported,  investments are generally  valued at the
mean between the last reported bid and asked prices.  If market  quotations  are
not readily available,  securities and other assets are valued by another method
that the Board of Directors believes  accurately  reflects fair value. Debt that
will mature in 60 days or less is valued on the basis of amortized  cost,  which
approximates  market value,  unless the Board  determines that using this method
would not reflect an investment's value.

   The books and  records of the  Portfolios  are  maintained  in U.S.  dollars.
Transactions  denominated  in foreign  currencies  are  recorded  at the current
prevailing  exchange rates.  All assets and  liabilities  denominated in foreign
currencies are translated into U.S. dollar amounts at the current  exchange rate
at the end of the period.  Translation gains or losses resulting from changes in
the exchange rate during the reporting  period and realized  gains and losses on
the settlement of foreign  currency  transactions are reported in the results of

realized gains and losses on investments in equity  securities  which are due to
changes  in the  foreign  exchange  rate from that  which are due to  changes in
market  prices of equity  securities.  The  Portfolios  isolate  that portion of

market prices of debt securities.

investments.   Such  risks  generally  include,  among  others,  currency  risk,
(fluctuations in currency exchange rates), information risk (key information may
be inaccurate or unavailable) and political risk (expropriation, nationalization
or the  imposition  of capital or currency  controls or punitive  taxes).  Other
risks of investing in foreign  securities include liquidity and valuation risks.
In addition,  focusing investment in a single country,  such as Japan,  involves
increased risks.

   Investments  in securities  of issuers  located in less  developed  countries
considered to be "emerging markets" involve risks in addition to those generally
applicable  to foreign  securities.  Investments  in the  securities  of issuers
located in emerging markets expose the Portfolio to economic structures that are
generally  less  diverse and mature than,  and to political  systems that can be
expected  to have  less  stability  than,  those  of  developed  countries.  The
typically  small  size of the  markets  for  securities  of  issuers  located in
emerging  markets  may also  result in a lack of  liquidity  and  greater  price
volatility.

   Security  transactions  are  accounted  for on a trade date  basis.  Interest
income  is  recorded  on  the  accrual  basis.  Dividends  are  recorded  on the
ex-dividend  date.  The cost of  investments  sold is  determined  by use of the
specific  identification  method  for both  financial  reporting  and income tax
purposes.

   Dividends  from net  investment  income  and  distributions  of net  realized
capital gains, if any, are declared and paid at least annually.  However, to the
extent  that a net  realized  capital  gain can be  reduced  by a  capital  loss
carryover,  such  gain  will  not  be  distributed.   Income  and  capital  gain
distributions  are determined in accordance  with federal income tax regulations
which may differ from generally accepted accounting principles.

   No provision is made for federal taxes as it is the Fund's  intention to have
each Portfolio continue to qualify for and elect the tax treatment applicable to
regulated  investment  companies  under the Internal  Revenue  Code of 1986,  as
amended,  (the "Code") and make the requisite  distributions to its shareholders
which will be sufficient to relieve it from federal income and excise taxes.

   The  Portfolios  may be subject to taxes  imposed by  countries in which they
invest,  with respect to their  investments in issuers  existing or operating in
such  countries.  Such taxes are generally based on income earned or repatriated
and capital  gains  realized  on the sale of such  investments.  The  Portfolios
accrue such taxes when the related income or capital gains are earned.

1. SIGNIFICANT ACCOUNTING POLICIES -- (CONT'D)

   Pursuant  to an  exemptive  order  issued  by  the  Securities  and  Exchange
Commission,  each  Portfolio,  along with other Funds  managed by Credit  Suisse
Asset Management LLC ("CSAM") can transfer  uninvested cash balances to a pooled
cash  account,  which is  invested  in  repurchase  agreements  secured  by U.S.
government   securities.   Securities   pledged  as  collateral  for  repurchase
agreements  are held by the  Portfolios'  custodian  bank  until the  agreements
mature.  Each  agreement  requires  that the market value of the  collateral  be
sufficient to cover payments of interest and principal; however, in the event of
default or  bankruptcy  by the other party to the  agreement,  retention  of the
collateral may be subject to legal  proceedings.  At April 30, 2000, none of the
Portfolios were invested in repurchase agreements.

   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  at the date of the
financial statement and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

   The Portfolios have an arrangement with their transfer agent whereby interest
earned on uninvested  cash balances was used to offset a portion of the transfer
agent expense.

   For the six months ended April 30, 2000, the Portfolios  received  credits or
reimbursements under this arrangement as follows:

3. LINE OF CREDIT

   The Portfolios, together with other Funds advised by CSAM, have established a
$250 million committed,  unsecured,  line of credit facility ("Credit Facility")
with Deutsche  Bank,  AG as  administrative  agent,  State Street Bank and Trust
Company  as  operations  agent,  Bank of Nova  Scotia as  syndication  agent and
certain other lenders, for temporary or emergency purposes primarily relating to
unanticipated  Portfolio  share  redemptions.  Under  the  terms  of the  Credit
Facility,  the  Funds  with  access  to the  Credit  Facility  pay an  aggregate
commitment  fee at a rate of .075% per annum on the average daily balance of the
Credit Facility that is undisbursed and uncanceled  during the preceding quarter
allocated among the  participating  Funds in such manner as is determined by the
governing Boards of the various Funds. In addition, the participating Funds will
pay interest on  borrowings  at the Federal  funds rate plus .50%.  At April 30,
2000, there were no loans outstanding for any of the Portfolios.  During the six
months ended April 30, 2000, the Portfolios had the following  borrowings  under
the Credit Facility:

   At April 30, 2000, the net unrealized appreciation from investments for those
securities  having  an  excess  of value  over  cost and net  depreciation  from
investments for those  securities  having an excess of cost over value (based on

5. FORWARD FOREIGN CURRENCY CONTRACTS

   Each Portfolio may enter into forward currency  contracts for the purchase or
sale of a specific foreign currency at a fixed price on a future date. Risks may
arise from  movements  in the value of a foreign  currency  relative to the U.S.
dollar and from the potential default of  counterparties to the contracts.  Each
Portfolio  will enter into forward  contracts  primarily  for hedging  purposes.
Forward  currency  contracts  are  adjusted  by the daily  exchange  rate of the
underlying currency and any gains or losses are recorded for financial statement
purposes as unrealized until the contract settlement date.

   At April 30, 2000, there were no open forward foreign  currency  contracts in
the Portfolios.

6. CAPITAL SHARE TRANSACTIONS

   The Fund is  authorized to issue up to thirteen  billion full and  fractional
shares of common  stock of separate  series  having a $.001 par value per share.
Shares of seven  series  have been  classified,  three of which  constitute  the
interest in the Portfolios.

   Transactions in shares of each Portfolio were as follows:
