WARBURG PINCUS TRUST -- INTERNATIONAL EQUITY PORTFOLIO
SEMIANNUAL INVESTMENT ADVISER'S REPORT -- JUNE 30, 1998

                                                                 August 10, 1998
 
Dear Shareholder:
 
  The objective of Warburg Pincus Trust -- International Equity Portfolio (the
"Portfolio") is long-term capital appreciation. The Portfolio pursues its
objective by investing primarily in a broadly diversified portfolio of equity
securities of companies that have their principal business activities and
interests outside the U.S.
 
  For the six months ended June 30, 1998, the Portfolio had a total return of
13.25%, vs. a return of 15.93% for the Morgan Stanley Capital International
Europe, Australasia and Far East ("EAFE") Index.* The Portfolio's one-year and
since-inception (on June 30, 1995) average annual total returns were -3.73% and
9.32%, respectively.
 
  The reporting period saw a marked divergence in performance among foreign
equity markets. European markets showed across-the-board strength, propelled by
robust corporate profits, improved economic growth and optimism toward the
prospects for European Monetary Union. Virtually all of Europe's markets had
double-digit gains for the period in U.S. dollar terms. The performance of most
other non-U.S. markets was less inspiring. Asian-Pacific markets generally fell,
with a number falling sharply, weighed down by worries over the region's
spiraling economic difficulties. Most Latin American markets also posted losses,
while the smaller emerging markets of Eastern Europe, the Middle East and Africa
were mixed.
 
  Warburg Pincus Trust -- International Equity Portfolio managed a healthy gain
for the period, albeit one that trailed the rise in its benchmark, the EAFE
Index. Most, if not all, of that underperformance stemmed from the Portfolio's
higher-than-index weighting in the Asia-Pacific region heading into the period.
Though the Portfolio's overweighting at the time was relatively small, virtually
any additional exposure to the region proved harmful in terms of relative
performance, particularly on an opportunity-cost basis, given the strong run-up
in European markets. (It should be noted that we reduced the Portfolio's
Asian-Pacific stake as the period progressed, based on a combination of
macroeconomic and company-specific concerns, and by period end the Portfolio was
underweighted vs. the EAFE Index.) For the same reason, the Portfolio was also
held back somewhat by its exposure to Latin America, a region not represented in
the benchmark.
 
  At the other end of the spectrum, performance-wise, the Portfolio saw very
strong gains from its holdings in Europe, benefiting from these markets' general
upward bias and from good stock selection. Among the better performers for the
Portfolio were its holdings in France and Italy, as well as its
 
                                       1

Nordic stocks collectively. We increased Europe's weighting in the Portfolio
steadily through the period, reflecting our belief that the region's positive
fundamental backdrop warranted a higher level of exposure, especially viewed
from a risk-adjusted perspective. This geographical shift -- i.e., into Europe,
at the expense of Asia -- was the most noteworthy strategic move in the
Portfolio during the six months.
 
  Looking out over the remainder of 1998 and into 1999, we see both substantial
opportunity and a fair amount of risk in foreign markets. Some of the most
promising investments continue to reside in Europe, we believe, given the
dynamics surrounding the launch of the single currency and the growing number of
positive developments on the corporate front. Particularly encouraging, with
regard to the latter, is the increasing emphasis among European corporate
managements on building shareholder value, a trend that suggests improved
efficiencies and rising per-share profitability over time. We also see pockets
of opportunity in Asia, including Japan, but are approaching these markets with
far greater degrees of caution, given the ongoing economic and political
uncertainties. The same holds for our approach to emerging markets in general.
 
  All told, we believe the Portfolio is well positioned, with regard to both
country weightings and specific holdings, to benefit from the type of investment
environment we foresee in the coming months, and we look forward to a positive
performance.

                                                                 August 10, 1998
 
Dear Shareholder:
 
  The objective of Warburg Pincus Trust -- Small Company Growth Portfolio (the
"Portfolio") is capital growth. The Portfolio pursues its objective by investing
in a portfolio of equity securities of small-sized domestic companies.
 
  For the six months ended June 30, 1998, the Portfolio had a total return of
4.79%, vs. returns of 5.46% for the Russell 2000 Growth Index* and 6.45% for the
Lipper Small Cap Funds Index.** The Portfolio's one-year and since-inception (on
June 30, 1995) average annual total returns were 18.13% and 19.98%,
respectively.
 
  The reporting period saw respectable gains, in general, for the types of
smaller-company, growth-oriented stocks in which the Portfolio invests.
Supporting the group were these companies' continued strong earnings growth,
both in absolute terms and relative to larger companies, and the stocks'
relatively attractive valuations. One factor that weighed on the group's
performance, though, at least in relative terms, was concern stemming from the
Asian financial crisis. Asia's difficulties triggered a general "flight to
quality" among investors, which worked to the advantage of large-cap, blue-chip
stocks at the expense of smaller issues. The net result was solid gains for
smaller-company stocks, albeit gains that lagged those of large-cap companies.
 
  Warburg Pincus Trust -- Small Company Growth Portfolio managed a healthy gain
for the period, though it trailed its benchmark by a narrow margin. In terms of
performance attribution, the Portfolio benefited from strong showings from
holdings in a number of areas, particularly business services, technology and
financial services. At the other end of the spectrum, performance-wise, were the
Portfolio's energy and oil-services stocks, which were hurt by concerns related
to falling oil prices and additional supply/demand worries.
 
  There were few significant changes in the Portfolio during the six months in
terms of its sector concentrations. The Portfolio remained broadly diversified
throughout, with slight overweightings in the consumer, financial and
business-services areas. This reflected our ability to find attractive
opportunities across a range of industries, as well as our desire to temper the
Portfolio's volatility by avoiding overconcentration in any one area.
 
  Looking ahead, our outlook on the prospects for small-cap growth stocks
remains largely positive, although investors' general bias toward large-cap

issues may limit the group's relative showing in the immediate term. Still,
based on trailing and projected profits, small caps' valuations now look more
attractive vs. those of large-cap issues than they have in nearly a decade. This
should, ultimately, draw increasing amounts of investor attention to the small-
cap arena in the coming months, which stands to be reflected in vastly improved
relative performance. All told, we remain optimistic, and will continue to
strive to identify those companies with the best prospects for appreciation.

WARBURG PINCUS TRUST -- POST-VENTURE CAPITAL PORTFOLIO
SEMIANNUAL INVESTMENT ADVISER'S REPORT -- JUNE 30, 1998
- --------------------------------------------------------------------------------
 
                                                                 August 10, 1998
 
Dear Shareholder:
 
  The objective of Warburg Pincus Trust -- Post-Venture Capital Portfolio (the
"Portfolio") is long-term growth of capital. The Portfolio pursues its objective
by investing primarily in equity securities of companies considered to be in
their post-venture-capital stage of development.
 
  For the six months ended June 30, 1998, the Portfolio had a return of 13.20%,
vs. a return of 5.46% for the Russell 2000 Growth Index* and 23.98% for the
Warburg Pincus/Venture Economics Post-Venture Capital Index (PVCI).** The
Portfolio's respective one-year and since-inception (on September 30, 1996)
average annual total returns as of June 30 were 24.10% and 13.71%.
 
  The period was a positive one for the types of stocks targeted by the
Portfolio, i.e., stocks of relatively young companies within the rapid-growth
industries favored by venture capitalists (e.g., the software, biotechnology and
communications industries). These stocks were, though, highly volatile, due to a
somewhat uncertain near-term earnings environment. Against this backdrop, the
Portfolio had a solid return, buoyed by its computer and consumer stocks in
particular. It did, however, lag the PVCI, due primarily to its underweighting
in certain large-cap Internet stocks that powered the index's advance. We viewed
most of these as expensive, and avoided them in favor of stocks we deemed to
have more reasonable valuations relative to their long-term prospects.
 
  We made few noteworthy changes to the Portfolio's industry exposure during the
period. We maintained a large presence in the technology area, where venture
capital has long played a critical role in the launch of breakthrough products
and services and should continue to do so. According to a recent study,***
research & development spending by venture-backed companies is growing at a rate
about three times that of Fortune 500 companies. In terms of specific
strategies, we continued to emphasize domestically oriented technology
companies, given the relatively difficult pricing environment faced by many
export-dependent companies. One stock we added was New Era of Networks, a
developer of application integration software products. The company, which went
public last June, focuses primarily on financial institutions, though it
continues to expand into other areas as well.
 
  Elsewhere, we maintained a significant weighting in the telecommunications &
equipment sector during the period. We believe this area will continue to
benefit from an ever-expanding Internet, ongoing worldwide deregulation of the
telecommunications industry and a high degree of innovation generally. Our
particular focus remained on competitive local exchange carriers ("CLECs"), such
as Intermedia Communications of Florida, which compete

directly with regional "Baby Bell" companies. Our other telecommunications
holdings during the period included Paging Network. The company, a recipient of
venture-capital financing in its start-up phase, went public in 1991 and
currently owns and operates the most extensive wireless communications network
in the U.S.
 
  The rest of the Portfolio was invested across a wide range of sectors,
including the financial, business-services, health-care and communications &
media areas. We also maintained a position in consumer-type stocks, where our
largest area of concentration at the end of the period was the leisure &
entertainment sector. This area increasingly stands to benefit from a maturing
population's growing levels of discretionary income, a trend that has not gone
unnoticed by venture-capital investors.
 
  Going forward, our outlook on the collective prospects for stocks of post-
venture companies (which we define as those that have received venture-capital
financing either during the early stages of the company's existence or the
development of a new product or service, or as part of a restructuring or
recapitalization -- the investment of venture-capital financing, distribution of
securities to venture-capital investors or initial public offering, whichever is
later, having been made within 10 years of the Portfolio's investment) remains
positive, and our efforts will continue to be devoted to identifying those with
the best long-term growth potential. We would caution investors, however, that
investing in venture-backed companies entails potential risks (e.g., that of
heightened volatility) along with the potential for significant long-term
rewards. Because of the nature of the Portfolio's holdings and certain
strategies it may use, an investment in the Portfolio should only be considered
for the aggressive portion of an investor's assets and may not be appropriate
for all investors. Investors should review the Prospectus carefully before
purchase.

Dear Shareholder:
 
  The objective of Warburg Pincus Trust -- Growth & Income Portfolio (the
"Portfolio") is long-term growth of capital and income and a reasonable current
return. The Portfolio pursues its objective by investing primarily in equity
securities.
 
  For the six months ended June 30, 1998, the Portfolio had a gain of 12.39%,
vs. gains of 17.70% for the S&P 500 Index* and 11.62% for the Lipper Growth &
Income Funds Index.** The Portfolio's total return since its inception (on
October 31, 1997) as of June 30 was 16.77%.
 
  The U.S. stock market as a whole had strong performance over the six months.
Asia-related earnings uncertainties notwithstanding, investor sentiment toward
equities remained favorable through the period, supported by a continued healthy
economy and subdued inflation. The Portfolio benefited from this positive
sentiment, and from good performances from its financial, telecommunications and
consumer holdings in particular. Stocks that hampered the Portfolio's return
included its energy and tobacco-related holdings, which lagged the broader
market during the period.
 
  We made few noteworthy changes to the Portfolio in terms of sector allocation
during the period. We remained well-diversified by industry, seeing little
incentive, from a risk-vs.-reward perspective, to heavily overweight specific
areas, given continued narrow stock valuations across and within sectors. That
said, we continued to select stocks strictly on a bottom-up basis, emphasizing
companies with good cash-flow generation and potential for significant earnings
growth.
 
  Our noteworthy areas of concentration included the financial-services
industry, a weighting we increased over the course of the period. We found
several attractive buying opportunities here during the six months, mostly in
the insurance area. Elsewhere in the financial industry, we maintained a limited
exposure to banking stocks, since we viewed most as expensive. We did, however,
find several issues we deemed to be attractively priced, including First Chicago
NBD, which we purchased in the wake of its announced merger with Banc One Corp.
In our view, the synergies created by the merger should support the stock's
long-term performance.
 
  We also maintained a significant weighting in the consumer area during the six
months. This included exposure to the consumer-durables sector, where our
largest position throughout the period was Chrysler. The stock contributed
positively to the Portfolio's performance for the period, rising
 
                                       7

sharply on news that it would merge with Daimler-Benz. We also continued to have
a significant weighting in the retail sector. Our noteworthy moves here included
selling our position in Wal-Mart, after it hit our sell target, and adding
Consolidated Stores, a brand-name retailer targeting cost-conscious consumers.
 
  Another noteworthy sector weighting during the period was the capital-
equipment area, where, as elsewhere, we remained focused on companies with
strong cash flows and good prospects for earnings improvements. Our largest
position here at the end of the period was ITT Industries, a designer and
manufacturer of products used in the automotive, fluid technology and defense &
electronics areas.
 
  The rest of the Portfolio was invested across of broad range of industries,
including technology, where we found the best risk-adjusted growth prospects in
the computer sector; health care, where we focused primarily on managed-care
companies with good pricing flexibility and steady enrollment growth; and
telecommunications & equipment, where we held both long-distance and local
service providers.
 
  Looking ahead to the next several months and beyond, we believe the stock
market will continue to be characterized by generally lofty equity valuations
and considerable volatility. As a result, we will continue to place a premium on
risk management, holding only those stocks we deem to have good longer-term
risk-adjusted performance potential.

SEMIANNUAL INVESTMENT ADVISER'S REPORT -- JUNE 30, 1998

Dear Shareholder:
 
  The objective of Warburg Pincus Trust -- Emerging Markets Portfolio (the
"Portfolio") is long-term growth of capital. The Portfolio pursues its objective
by investing primarily in equity securities of non-United States issuers
consisting of companies in emerging securities markets.
 
  For the six months ended June 30, 1998, the Portfolio had a total return of
- -4.70%, vs. returns of -18.87% for the Morgan Stanley Capital International
Emerging Markets Free Index* and -17.00% for the Lipper Emerging Markets Funds
Index.**
 
  The six months was an extremely difficult period for emerging markets, due in
large measure to the continued economic and financial instability in the
Asian-Pacific region. The region's woes cast a pall over emerging markets
collectively, with investors largely shunning the group in favor of the
developed markets of the U.S. and Europe. While a handful of emerging markets
managed gains for the period, notably several from the Middle East and Eastern
Europe, the vast majority fell, and many fell sharply, with losses in excess of
20% in dollar terms more the rule than the exception.
 
  Set against this backdrop, the Portfolio lost 4.70% over the six months, a
disappointing showing in absolute terms but a strong one vs. relevant
benchmarks. The Portfolio's relative strength was attributable to a combination
of timely regional allocations -- specifically, we had relatively limited
exposure to the hard-hit Southeast Asian markets through the period, and a
relatively large weighting in the Middle East and Eastern Europe (e.g., in
Israel and Poland, two markets that posted solid gains) -- and to the fact that
we had an atypically large cash weighting in January, a particularly bad month
for the asset class. (The Portfolio commenced operations on December 31, 1997.)
 
  Looking ahead, our near- to immediate-term outlook on emerging markets is
somewhat guarded, given the still-unsettled environment in Asia and investors'
general wariness toward the asset class. Our longer-term outlook remains
positive, however. Most of these markets, after their recent setbacks, are now
significantly below their all-time highs, and stock valuations have been driven
down to, in many cases, record-low levels. We believe this has created a
substantial amount of opportunity for selective, risk-tolerant investors who are
willing to take a longer-term (i.e., minimum two- to three-year) outlook.
Accordingly, we continue to devote our efforts to identifying

those businesses with the best individual prospects, and believe those efforts
will prove rewarding to shareholders over time.
 
  As ever, though, the potential for short-term volatility remains, given the
nature of emerging markets, and we would encourage investors to approach the
asset class with a realistic view of the potential risks involved.

1. SIGNIFICANT ACCOUNTING POLICIES
 
  Warburg Pincus Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers five investment funds (the "Portfolios"): International Equity
Portfolio is a diversified investment fund that seeks long-term capital
appreciation by investing primarily in a broadly diversified portfolio of equity
securities of companies that have their principal business activities and
interests outside of the U.S.; Small Company Growth Portfolio is a
non-diversified investment fund that seeks capital growth by investing in a
portfolio of equity securities of small-sized domestic companies; Post-Venture
Capital Portfolio is a diversified investment fund that seeks long-term growth
of capital by investing primarily in equity securities, of companies considered
to be in their post-venture-capital stage of development; Growth & Income
Portfolio is a diversified investment fund that seeks long-term growth of
capital and income by investing primarily in equity securities;and Emerging
Markets Portfolio is a non-diversified investment fund that seeks long-term
growth of capital by investing primarily in equity securities of non-United
States issuers consisting of companies in emerging securities markets. Shares of
a Portfolio are not available directly to individual investors but may be
offered only to certain (a) life insurance companies for allocation to certain
of their separate accounts established for the purpose of funding variable
annuity contracts and variable life insurance contracts and (b) tax-qualified
pension and retirement plans ("Plans"), including participant-directed Plans
which elect to make a Portfolio an investment option for Plan participants.
 
  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. In the absence of market
quotations, investments are generally valued at fair value as determined by or
under the direction of the Trust's Board of Trustees. Short-term investments
that mature in 60 days or less are valued on the basis of amortized cost, which
approximates market 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

1. SIGNIFICANT ACCOUNTING POLICIES -- (CONT'D)
the settlement of foreign currency transactions are reported in the results of
operations for the current period. The Portfolios do not isolate that portion of
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 gains and losses on
investments in debt securities which are due to changes in the foreign exchange
rate from that which are due to changes in market prices of debt securities.
 
  The International Equity Portfolio may invest in securities of foreign
countries and governments which involve certain risks in addition to those
inherent in domestic investments. Such risks generally include, among other
things, fluctuations in currency exchange rates, revaluation of currencies,
future adverse political and economic developments and the imposition of other
foreign laws and restrictions. Securities of foreign issuers are often subject
to less rigorous regulatory practices and requirements than those applied in the
United States and may also be less liquid (and their prices more volatile) than
securities of comparable U.S. companies. Moreover, individual foreign economies
may differ favorably or unfavorably from the U.S. economy in many respects.
 
  A Portfolio's 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 Trust 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.
 
  When a Portfolio writes or purchases a call or a put option, an amount equal
to the premium received or paid by the Portfolio is recorded as a liability or
asset, the value of which is marked-to-market daily to reflect the current
market value of the option. When the option expires, the Portfolio realizes a
gain or loss equal to the amount of the premium received or paid. When the
Portfolio exercises an option or enters into a closing transaction by purchasing
or selling an offsetting option, it realizes a gain or loss without regard to
any unrealized gain in the underlying security. The potential loss associated
with purchasing an option is limited to the premium paid, and the premium would
partially offset any gains achieved from its use.

1. SIGNIFICANT ACCOUNTING POLICIES -- (CONT'D)
  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 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.
 
  For U.S. federal income tax purposes, realized losses incurred after October
31, 1997, within the fiscal year, are deemed to arise on the first business day
of the following fiscal year. The International Equity Portfolio incurred and
elected to defer such losses of $25,346,474.
 
  No provision is made for federal income taxes as it is the Trust'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 and
make the requisite distributions to its shareholders which will be sufficient to
relieve it from federal income and excise taxes.
 
  Costs incurred by the Trust in connection with its organization have been
deferred and are being amortized over a period of five years from the date the
Trust commenced its operations. Costs incurred by the Portfolios in connection
with the offering of their shares have been deferred and are being amortized
over a one year period from the date each Portfolio commenced its operations.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, each Portfolio, along with other funds advised by Warburg Pincus
Asset Management, Inc., the Portfolios' investment adviser ("Warburg")
(collectively the "Warburg Funds"), transfers uninvested cash balances to a
Pooled Cash Account, which is invested in repurchase agreements collateralized
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.

1. SIGNIFICANT ACCOUNTING POLICIES -- (CONT'D)
 
  The Portfolios, together with other Warburg Funds, have established committed
and uncommitted lines of credit facilities with PNC Bank, National Association
("PNC") and an uncommitted line of credit facility with Deutsche Bank, AG
("Deutsche Bank") for temporary or emergency purposes primarily relating to
unanticipated fund share redemptions. Effective December 31, 1997, the terms of
the committed line of credit with PNC were amended. Under the terms of the
committed line of credit, the Warburg Funds with access to the facility pay a
commitment fee at a rate of .07% per annum on the average daily balance of the
line of credit, which is undisbursed and uncanceled during the preceding
quarter. In addition, the Warburg Funds will pay interest on borrowings at the
bank's base rate plus .45%. Under the terms of the uncommitted lines of credit,
the Warburg funds will pay interest on borrowings at the bank's base rate plus
 .55%. Aggregate borrowings for each fund under the committed and uncommitted
lines of credit with PNC may not exceed the lowest of (a) thirty-three and
one-third percent (33 1/3%) of the assets of such fund, for any Fund that does
not invest at least sixty-five percent (65%) of its assets in international
equity or fixed income securities (an "International Fund") and twenty-five
percent (25%) of the assets of any Fund that is an International Fund or (b) the
maximum amount permitted by such fund's investment policies and restrictions.
Aggregate borrowings for each fund under the uncommitted line of credit facility
with Deutsche Bank may not exceed thirty-three and one-third percent (33 1/3%)
of the net assets of such fund. At June 30, 1998 and during the six months ended
June 30, 1998, none of the Portfolios had borrowings under those lines of credit
facilities.
 
  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 their
transfer agent expense. For the period ended June 30, 1998, the Portfolios
received credits or reimbursements under the arrangement as follows:

4. FORWARD FOREIGN CURRENCY CONTRACTS
 
  The Portfolios 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 upon entering into these contracts from the potential inability of
counterparties to meet the terms of their contracts and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar. The
Portfolios will enter into forward contracts primarily for hedging purposes. The
forward currency contracts are adjusted daily 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 June 30, 1998, the International Equity Portfolio had the following open
forward currency contract:

6. EQUITY SWAP TRANSACTIONS -- (CONT'D)
In return, the Portfolio pays quarterly the LIBOR rate (London Interbank Offered
Rate), plus 2.00% per annum on the market value of the Common Stocks ("Notional
Amount"). The Notional Amount is marked-to-market on each quarterly reset date.
In the event that the Common Stocks decline in value, the Portfolio will be
required to pay quarterly, the amount of any depreciation in value from the
Notional Amount.
 
  During the term of the equity swap transaction, changes in the value of the
Common Stocks as compared to the Notional Amount and the difference between the
accrued interest expense and dividend income are recognized as unrealized gain
or loss. At the quarterly reset date, the change in value of the Common Stock
adjusted for accrued interest expense and dividend income, is recognized as
realized gain or loss. At June 30, 1998, the Portfolio no longer held a position
in the swap.
 
7. CAPITAL SHARE TRANSACTIONS
 
  Each Portfolio is authorized to issue an unlimited number of full and
fractional shares of beneficial interest, par value of $.001 per share.

9. NET ASSETS
 
  At June 30, 1998, capital contributions, undistributed net investment income,
accumulated net realized gain/(loss) from security transactions and current
period distributions have been adjusted for current period permanent book/tax
differences which arose principally from differing book/tax treatments of
foreign currency and equity swap transactions. The International Equity
Portfolio reclassified $689,884 from accumulated net realized loss from security
transactions to undistributed net investment income. The Small Company Growth
Portfolio and the Post-Venture Capital Portfolio reclassified $2,695,081 and
$230,241, respectively, from accumulated net investment loss to capital
contributions. Net investment income, net realized gain/(loss) on investments
and net assets were not affected by this reclassification.
 
  Net assets at June 30, 1998, consisted of the following:

11. YEAR 2000 COMPLIANCE
 
  Many services provided to the Portfolios and their shareholders by Warburg and
certain of its affiliates (the "Warburg Service Providers") and the Portfolios'
other service providers rely on the functioning of their respective computer
systems. Many computer systems cannot distinguish the year 2000 from the year
1900, resulting in potential difficulty in performing various calculations (the
"Year 2000 Issue"). The Year 2000 Issue could potentially have an adverse impact
on the handling of security trades, the payment of interest and dividends,
pricing, account services and other Portfolio operations.
 
  The Warburg Service Providers recognize the importance of the Year 2000 Issue
and are taking appropriate steps necessary in preparation for the year 2000. At
this time, there can be no assurance that these steps will be sufficient to
avoid any adverse impact on the Portfolios nor can there be any assurance that
the Year 2000 Issue will not have an adverse effect on the Portfolios'
investments or on global markets or economies, generally. In addition, it has
been reported that foreign institutions have made less progress in addressing
the Year 2000 Issue than major U.S. entities, which could adversely effect the
Portfolios' foreign investments.
 
  The Warburg Service Providers anticipate that their systems and those of the
Portfolios' other service providers will be adapted in time for the year 2000.
To further this goal, the Warburg Service Providers have coordinated a plan to
repair, adapt or replace systems that are not year 2000 compliant, and are
seeking to obtain similar representations from the Portfolios' other major
service providers. The Warburg Service Providers will be monitoring the Year
2000 Issue in an effort to ensure appropriate preparation.
