           Commission has not approved these funds, nor has it passed
           upon the adequacy or accuracy of this Prospectus. It is a

           Warburg Pincus Funds are advised by Credit Suisse Asset

    SUPPLEMENT TO THE PROSPECTUSES AND STATEMENTS OF ADDITIONAL INFORMATION

                          WARBURG PINCUS VALUE II FUND
                   WARBURG PINCUS SMALL COMPANY VALUE II FUND

The following information supersedes certain information in the funds'
Prospectuses and Statements of Additional Information.

                                  FUND MERGERS

     The consummation of the previously announced acquisition of Donaldson,
Lufkin & Jenrette, Inc. ("DLJ") by Credit Suisse Group ("Credit Suisse")
occurred on November 3, 2000, following which the assets and business of DLJ
Asset Management Group, Inc. were transferred to Credit Suisse Asset Management,
LLC ("CSAM").

     To rationalize the management of the funds and the former DLJ family of
funds managed by CSAM (now called the Credit Suisse Warburg Pincus Funds), CSAM
has proposed, and the Board of Directors of each fund has approved for
submission to shareholders at meetings scheduled for late May 2001 as more fully
explained below, the combinations of the funds (each, an "Acquired Fund") into
similar funds within the Credit Suisse Warburg Pincus Funds (each, an "Acquiring
Fund").

     The Board of Directors of each Acquired Fund has approved a proposed
reorganization (each, an "Acquisition") where the assets of an Acquired Fund
would be acquired by the relevant Acquiring Fund. The Acquisition will involve
an exchange of shares of an Acquiring Fund for all of the assets of the relevant
Acquired Fund. The Acquired Funds would then be liquidated and shares of the
relevant Acquiring Fund would be distributed to the Acquired Fund's
shareholders. The Acquisition will not result in any material changes to the
goal or investment operations of the Acquired Funds since each of the Acquiring
Funds has an investment objective and strategies similar to the investment
objective and strategies of the corresponding Acquired Fund.

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


     If the Acquisition is completed, each shareholder of an Acquired Fund would
become a shareholder of the respective Acquiring Fund and receive shares of the
appropriate class of that Acquiring Fund with a value equal to the value of the
shareholder's investment in the relevant Acquired Fund. Each Acquisition is not
expected to result in any gain or loss for federal income tax purposes to an
Acquired Fund's shareholders.

     The investment advisory fees of the Acquiring Funds would be lower in each
case than the corresponding Acquired Funds, and CSAM has agreed to reimburse
expenses of each Acquiring Fund as necessary so that for the two-year period
following the consummation of each Acquisition the total annual expense ratio of
each Acquiring Fund would not be greater than the expense ratio of either the
Acquiring Fund or the Acquired Fund for the 60-day period prior to consummation
of the Acquisition.

     The Acquisition is subject to the completion of certain conditions,
including the approval of shareholders of the respective Acquired Fund. Proxy
materials describing the proposed Acquisitions will be mailed to shareholders of
the Acquired Funds in anticipation of a special meeting of shareholders to be
held on or about May 25, 2001. If approved by shareholders, the Acquisitions
will occur shortly after the meeting.

Dated: February 28, 2001                                                 16-0201

     INVESTOR PROFILE

   THESE FUNDS ARE DESIGNED FOR INVESTORS WHO:

 - are investing for long-term goals that may include college or retirement

 - are willing to assume the risk of losing money in exchange for attractive
  potential long-term returns

 - are investing for capital appreciation

 - want to diversify their portfolios with more aggressive stock funds

   THEY MAY NOT BE APPROPRIATE IF YOU:

 - are investing for a shorter time horizon

 - are uncomfortable with an investment that will fluctuate in value

 - are looking for income

   You should base your selection of a fund on your own goals, risk preferences
and time horizon.


     A WORD ABOUT RISK

   All investments involve some level of risk. Simply defined, risk is the
possibility that you will lose money or not make money.

   Principal risk factors for the funds are discussed below. Before you invest,
please make sure you understand the risks that apply to your fund. As with any
mutual fund, you could lose money over any period of time.

   Investments in the funds are not bank deposits and are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

MARKET RISK
All funds

   The market value of a security may move up and down, sometimes rapidly and
unpredictably. These fluctuations, which are often referred to as "volatility,"
may cause a security to be worth less than it was worth at an earlier time.
Market risk may affect a single issuer, industry, sector of the economy, or the
market as a whole. Market risk is common to most investments--including stocks
and bonds, and the mutual funds that invest in them.

START-UP AND OTHER SMALL COMPANIES
All funds

   Start-up and other small companies may have less-experienced management,
limited product lines, unproven track records or inadequate capital reserves.
Their securities may carry increased market, liquidity and other risks. Key
information about the company may be inaccurate or unavailable.

SPECIAL-SITUATION COMPANIES
All funds

   "Special situations" are unusual developments that affect a company's market
value. Examples include mergers, acquisitions and reorganizations. Securities of
special-situation companies may decline in value if the anticipated benefits of
the special situation do not materialize.

NON-DIVERSIFIED STATUS
Emerging Growth Fund

   The fund is considered a non-diversified investment company under the
Investment Company Act of 1940 and is permitted to invest a greater proportion
of its assets in the securities of a smaller number of issuers. As a result, the
fund may be subject to greater volatility with respect to its portfolio
securities than a fund that is more broadly diversified.


                              PERFORMANCE SUMMARY

The bar chart below and the table on the next page provide an indication of the
risks of investing in these funds. The bar chart shows you how each fund's
performance has varied from year to year for up to 10 years. The table compares
each fund's performance over time to that of a broadly based securities market
index and other indexes, if applicable. As with all mutual funds, past
performance is not a prediction of the future.

(1) The Russell 2000 Growth Index is an unmanaged index (with no defined
    investment objective) of those securities in the Russell 2000 Index with a
    greater-than-average growth orientation. The Russell 2000 Growth Index
    includes reinvestment of dividends, and is compiled by Frank Russell
    Company.

(2) Performance since January 31, 1988.

(3) The Russell 2500 Growth Index measures the performance of those companies in
    the Russell 2500 Index with higher price-to-book values and higher
    forecasted growth rates. The Russell 2500 Index is composed of the 2,500
    smallest companies in the Russell 3000 Index, which measures the performance
    of the 3000 largest U.S. companies based on total market capitalization. The
    Russell 2500 Index represents approximately 22% of the total market
    capitalization of the Russell 3000 Index.

(4) The Russell 2000 Index is an unmanaged index (with no defined investment
    objective) of approximately 2,000 small-cap stocks, includes reinvestment of
    dividends, and is compiled by Frank Russell Company.

                           UNDERSTANDING PERFORMANCE

   - TOTAL RETURN tells you how much an investment in a fund has changed in
    value over a given time period. It assumes that all dividends and capital
    gains (if any) were reinvested in additional shares. The change in value
    can be stated either as a cumulative return or as an average annual rate
    of return.

   - A CUMULATIVE TOTAL RETURN is the actual return of an investment for a
    specified period. The year-by-year total returns in the bar chart are
    examples of one-year cumulative total returns.

   - An AVERAGE ANNUAL TOTAL RETURN applies to periods longer than one year.
    It smoothes out the variations in year-by-year performance to tell you
    what constant annual return would have produced the investment's actual
    cumulative return. This gives you an idea of an investment's annual
    contribution to your portfolio, assuming you held it for the entire
    period.

   - Because of compounding, the average annual total returns in the table
    cannot be computed by averaging the returns in the bar chart.

This example may help you compare the cost of investing in these funds with the
cost of investing in other mutual funds. Because it uses hypothetical
conditions, your actual costs may be higher or lower.

Assume you invest $10,000, each fund returns 5% annually, expense ratios remain
as listed in the first table on the opposite page (before fee waivers and
expense reimbursements or credits) and you close your account at the end of each
of the time periods shown. Based on these assumptions, your cost would be:

                              EMERGING GROWTH FUND

     GOAL AND STRATEGIES

   The Emerging Growth Fund seeks maximum capital appreciation. To pursue this
goal, it invests in equity securities of emerging-growth companies.

   Emerging-growth companies are small or medium-size companies that:

 - have passed their start-up phase

 - show positive earnings

 - offer the potential for accelerated earnings growth

   Emerging-growth companies generally stand to benefit from new products or
services, technological developments, management changes or other factors. They
include "special-situation companies"--companies experiencing unusual
developments affecting their market value.

   Under normal market conditions, the fund will invest at least 65% of assets
in equity securities of emerging-growth companies that represent attractive
capital-appreciation opportunities.

   Its non-diversified status allows the fund to invest a greater share of its
assets in the securities of fewer companies.

     PORTFOLIO INVESTMENTS

   This fund invests in a portfolio of U.S. equity securities consisting of:

 - common and preferred stocks

 - securities convertible into common stocks

 - rights and warrants

   The fund may invest up to 10% of assets in foreign securities. To a limited
extent, it may also engage in other investment practices.

     RISK FACTORS

   This fund's principal risk factors are:

 - market risk

 - start-up and other small companies

 - special-situation companies

 - non-diversified status

   The value of your investment generally will fluctuate in response to
stock-market movements. Fund performance will largely depend upon the
performance of growth stocks, which may be more volatile than the overall stock
market.

   Different types of stocks (such as "growth" vs. "value" stocks) tend to shift
in and out of favor depending on market and economic conditions. Accordingly,
the fund's performance may sometimes be lower or higher than that of other types
of funds (such as those emphasizing value stocks).

   Investing in start-up and other small companies may expose the fund to
increased market, liquidity and information risks. These risks are defined in
"More About Risk."

   Securities of companies in special situations may decline in value and hurt
the fund's performance if the anticipated benefits of the special situation do
not materialize. Non-diversification might cause the fund to be more volatile
than a diversified fund.

   "More About Risk" details certain other investment practices the fund may
use. Please read that section carefully before you invest.

                          SMALL COMPANY VALUE II FUND

     GOAL AND STRATEGIES

   The Small Company Value II Fund seeks long-term capital appreciation. To
pursue this goal, it invests in equity securities of small U.S. value companies.
Current income is a secondary consideration in selecting portfolio investments.

   Value companies are companies whose earnings power or asset value does not
appear to be reflected in the current stock price. As a result, value companies
look underpriced according to financial measurements of their intrinsic worth or
business prospects. These measurements include price-to-earnings, price-to-book,
price-to-cash flow and debt-to-equity ratios. The portfolio managers determine
value based upon research and analysis, taking all relevant factors into
account.

   Under normal market conditions, the fund will invest at least 65% of assets
in equity securities of small U.S. companies. The fund considers a "small"
company to be one whose market capitalization is within the range of
capitalizations of companies in the Russell 2000 Index. As
of December 31, 2000, market capitalizations of Russell 2000 companies ranged
from approximately $4 million to $6.1 billion.

   Some companies may outgrow the definition of a small company after the fund
has purchased their securities. These companies continue to be considered small
for purposes of the fund's 65% minimum allocation to small-company equities. In
addition, the fund may invest in companies of any size once the 65% policy is
met. As a result, the fund's average market capitalization may sometimes exceed
that of the largest company in the Russell 2000 Index.

     PORTFOLIO INVESTMENTS

   This fund invests primarily in equity securities of small-capitalization
value companies. Equity holdings may consist of:

 - common and preferred stocks

 - securities convertible into common stocks

 - rights and warrants

   The fund may invest up to 10% of assets in foreign securities. To a limited
extent, it may also engage in other investment practices.

     RISK FACTORS

   This fund's principal risk factors are:

 - market risk

 - start-up and other small companies

 - special-situation companies

   The value of your investment generally will fluctuate in response to
stock-market movements.

   Different types of stocks (such as "growth" vs. "value" stocks) tend to shift
in and out of favor depending on market and economic conditions. Accordingly,
the fund's performance may sometimes be lower or higher than that of other types
of funds (such as those emphasizing growth stocks).

   Investing in start-up and other small companies may expose the fund to
increased market, liquidity and


information risks. These risks are defined in "More About Risk."

   Small companies are often involved in "special situations." Securities of
special-situation companies may decline in value and hurt the fund's performance
if the anticipated benefits of the special situation do not materialize. "More
About Risk" details certain other investment practices the fund may use. Please

                           SMALL COMPANY GROWTH FUND

     GOAL AND STRATEGIES

   The Small Company Growth Fund seeks capital growth. To pursue this goal, it
invests in equity securities of small U.S. growth companies.

   In seeking to identify growth companies--companies with attractive
capital-growth potential--the fund's portfolio managers often look for:

 - companies still in the developmental stage

 - older companies that appear to be entering a new stage of growth

 - companies providing products or services with a high unit-volume growth rate

   The fund may also invest in emerging-growth companies--small or medium-size
companies that have passed their start-up phase, show positive earnings, and
offer the potential for accelerated earnings growth. Emerging-growth companies
generally stand to benefit from new products or services, technological
developments, changes in management or other factors.

   Under normal market conditions, the fund will invest at least 65% of assets
in equity securities of small U.S. companies. The fund considers a "small"
company to be one whose market capitalization is within the range of
capitalizations of companies in the Russell 2000 Index. As of December 31, 2000,
market capitalizations of Russell 2000 companies ranged from $4 million to $6.1
billion.

   Some companies may outgrow the definition of a small company after the fund
has purchased their securities. These companies continue to be considered small
for purposes of the fund's minimum 65% allocation to small-company equities. In
addition, the fund may invest in companies of any size once the 65% policy is
met. As a result, the fund's average market capitalization may sometimes exceed
that of the largest company in the Russell 2000 Index.

     PORTFOLIO INVESTMENTS

   This fund intends to invest at least 80% of assets in equity securities of
small-capitalization growth companies. Equity holdings may consist of:

 - common and preferred stocks

 - securities convertible into common stocks

 - rights and warrants

   The fund may invest up to 10% of assets in foreign securities. To a limited
extent, it may also engage in other investment practices.

     RISK FACTORS

   This fund's principal risk factors are:

 - market risk

 - start-up and other small companies

 - special-situation companies

   The value of your investment generally will fluctuate in response to
stock-market movements. Fund performance will largely depend upon the
performance of growth stocks, which may be more volatile than the overall stock
market.

   Different types of stocks (such as "growth" vs. "value" stocks) tend to shift
in and out of favor depending on market and economic conditions. Accordingly,
the fund's performance may sometimes be lower or higher than that of other types
of funds (such as those emphasizing value stocks).

   Investing in start-up and other small companies may expose the fund to


increased market, liquidity and information risks. These risks are defined in
"More About Risk."

   Small companies and emerging-growth companies are often involved in "special
situations." Securities of special-situation companies may decline in value and
hurt the fund's performance if the anticipated benefits of the special situation
do not materialize.

   "More About Risk" details certain other investment practices the fund may
use. Please read that section carefully before you invest.

                                MORE ABOUT RISK

     INTRODUCTION

   A fund's goal and principal strategies largely determine its risk profile.
You will find a concise description of each fund's risk profile in "Key Points."
The fund-by-fund discussions contain more detailed information. This section
discusses other risks that may affect the funds.

   The funds may use certain investment practices that have higher risks
associated with them. However, each fund has limitations and policies designed
to reduce many of the risks. The "Certain Investment Practices" table describes
these practices and the limitations on their use.

     TYPES OF INVESTMENT RISK

   The following risks are referred to throughout this Prospectus.

   CORRELATION RISK The risk that changes in the value of a hedging instrument
will not match those of the investment being hedged.

   CREDIT RISK The issuer of a security or the counterparty to a contract may
default or otherwise become unable to honor a financial obligation.

   CURRENCY RISK Fluctuations in exchange rates between the U.S. dollar and
foreign currencies may negatively affect an investment. Adverse changes in
exchange rates may erode or reverse any gains produced by foreign-currency-
denominated investments and may widen any losses.

   EXPOSURE RISK The risk associated with investments (such as derivatives) or
practices (such as short selling) that increase the amount of money a fund could
gain or lose on an investment.

    - HEDGED Exposure risk could multiply losses generated by a derivative or
     practice used for hedging purposes. Such losses should be substantially
     offset by gains on the hedged investment. However, while hedging can reduce
     or eliminate losses, it can also reduce or eliminate gains.

    - SPECULATIVE To the extent that a derivative or practice is not used as a
     hedge, the fund is directly exposed to its risks. Gains or losses from
     speculative positions in a derivative may be much greater than the
     derivative's original cost. For example, potential losses
      from writing uncovered call options and from speculative short sales
      are unlimited.

   INFORMATION RISK Key information about an issuer, security or market may be
inaccurate or unavailable.

   INTEREST-RATE RISK Changes in interest rates may cause a decline in the
market value of an investment. With bonds and other fixed-income securities, a
rise in interest rates typically causes a fall in values, while a fall in
interest rates typically causes a rise in values.


   LIQUIDITY RISK Certain fund securities may be difficult or impossible to sell
at the time and the price that the fund would like. A fund may have to lower the
price, sell other securities instead or forego an investment opportunity. Any of
these could have a negative effect on fund management or performance.

   MARKET RISK The market value of a security may move up and down, sometimes
rapidly and unpredictably. These fluctuations, which are often referred to as
"volatility," may cause a security to be worth less than it was worth at an
earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. Market risk is common to most
investments--including stocks and bonds, and the mutual funds that invest in
them.

   OPERATIONAL RISK Some countries have less-developed securities markets (and
related transaction, registration and custody practices) that could subject a
fund to losses from fraud, negligence, delay or other actions.

   POLITICAL RISK Foreign governments may expropriate assets, impose capital or
currency controls, impose punitive taxes, or nationalize a company or industry.
Any of these actions could have a severe effect on security prices and impair a
fund's ability to bring its capital or income back to the U.S. Other political
risks include economic policy changes, social and political instability,
military action and war.

   VALUATION RISK The lack of an active trading market may make it difficult to
obtain an accurate price for a fund security.

                               ABOUT YOUR ACCOUNT

     SHARE VALUATION

   The price of your shares is also referred to as their net asset value (NAV).

   The NAV is determined at the close of regular trading on the New York Stock
Exchange (NYSE) (usually 4 p.m. Eastern Time) each day the NYSE is open for
business. It is calculated by dividing the Common Class's total assets, less its
liabilities, by the number of Common Class shares outstanding.

   Each fund values its securities based on market quotations when it calculates
its NAV. 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 obligations that will mature in 60 days or
less are valued on the basis of amortized cost, unless the Board of Directors
determines that using this method would not reflect an investment's value.

   Some fund securities may be listed on foreign exchanges that are open on days
(such as U.S. holidays) when the funds do not compute their prices. This could
cause the value of a fund's portfolio investments to be affected by trading on
days when you cannot buy or sell shares.

     BUYING AND SELLING SHARES

   The accompanying Shareholder Guide explains how to invest directly with the
funds. You will find information about purchases, redemptions, exchanges and
services.

   Each fund is open on those days when the NYSE is open, typically Monday
through Friday. If we receive your request in proper form by the close of the
NYSE (usually 4 p.m. ET), your transaction will be priced at that day's NAV. If
we receive it after that time, it will be priced at the next business day's NAV.

FINANCIAL-SERVICES FIRMS

   You can also buy and sell fund shares through a variety of financial-services
firms such as banks, brokers and financial advisors. The funds have authorized
these firms (and other intermediaries that the firms may designate) to accept
orders. When an authorized firm or its designee has received your order, it is
considered received by the fund and will be priced at the next-computed NAV.

   Financial-services firms may charge transaction fees or other fees that you
could avoid by investing directly with the funds. Please read their program
materials for any special provisions or additional service features that may
apply to your investment. Certain features of the funds, such as the minimum
initial or subsequent investment amounts, may
be modified.

   Some of the firms through which the funds are available include:

 - Charles Schwab & Co., Inc. Mutual Fund OneSource(R) service

 - Fidelity Brokerage Services, Inc. FundsNetwork(TM) Funds

 - TD Waterhouse Securities, Inc.


     ACCOUNT STATEMENTS

   In general, you will receive account statements or notices as follows:

 - after every transaction that affects your account balance (except for
  distribution reinvestments and automatic transactions)

 - after any changes of name or address of the registered owner(s)

 - otherwise, every quarter

   You will also receive annual and semiannual financial reports.

     DISTRIBUTIONS

   As a fund investor, you will receive distributions.

   Each fund may earn dividends from stocks and interest from bond, money-
market and other investments. These are passed along as dividend distributions.
A fund realizes capital gains whenever it sells securities for a higher price
than it paid for them. These are passed along as capital-gain distributions.

   The funds typically distribute dividends and capital gains annually, usually
in December.

   Most investors have their distributions reinvested in additional shares of
the same fund. Distributions will be reinvested unless you choose on your
account application to have a check for your distributions mailed to you or sent
by electronic transfer.

   Estimated year-end distribution information, including record and payment
dates, will be available late in the year at www.warburg.com or by calling
800-WARBURG (800-927-2874). Investors are encouraged to consider the potential
tax consequences of distributions prior to buying or selling shares of the
funds.

     TAXES

   As with any investment, you should consider how your investment in a fund
will be taxed. If your account is not a tax-advantaged retirement account, you
should be especially aware of the following potential tax implications. Please
consult your tax professional concerning your own tax situation.

TAXES ON DISTRIBUTIONS

   As long as a fund continues to meet the requirements for being a
tax-qualified regulated investment company, it pays no federal income tax on the
earnings it distributes to shareholders.

   Distributions you receive from a fund, whether reinvested or taken in cash,
are generally considered taxable. Distributions from a fund's long-term capital
gains are taxed as long-term capital gains regardless of how long you have held
fund shares. Distributions from other sources (including the fund's short-term
capital gains) are generally taxed as ordinary income. The funds will mostly
make capital-gain distributions, which will be largely derived from the fund's
short-term or long-term capital gains.


   If you buy shares shortly before or on the "record date"--the date that
establishes you as the person to receive the upcoming distribution--you may
receive a portion of the money you just invested in the form of a taxable
distribution.

   The Form 1099-DIV that is mailed to you every January details your
distributions and their federal-tax category, including the portion taxable as
long-term capital gain.

TAXES ON TRANSACTIONS

   Any time you sell or exchange shares, it is considered a taxable event for
you. Depending on the purchase price and the sale price of the shares you sell
or exchange, you may have a gain or loss on the transaction. You are responsible
for any tax liabilities generated by your transactions.


                               OTHER INFORMATION

     ABOUT THE DISTRIBUTOR

   Credit Suisse Asset Management Securities, Inc. (CSAMSI), an affiliate of
CSAM, is responsible for:

 - making the funds available to you

 - account servicing and maintenance

 - other administrative services related to sale of the Common Class

   As part of their business strategies, the Small Company Value II Fund and the
Small Company Growth Fund have each adopted a Rule 12b-1 shareholder-servicing
and distribution plan to compensate CSAMSI for providing certain shareholder and
other services related to the sale of the Common Class. Under the plan, CSAMSI
receives fees at an annual rate of 0.25% of average daily net assets of the
fund's Common Class. Because the fees are paid out of the fund's assets on an
ongoing basis, over time they will increase the cost of your investment and may
cost you more than paying other types of sales charges.

   With respect to each of the funds, CSAMSI, CSAM or their affiliates may make
additional payments out of their own resources to firms offering Common Class
shares for providing administration, subaccounting, transfer agency and/or other
services. Under certain circumstances, the funds may reimburse a portion of
these payments.

     INVESTOR PROFILE

   THIS FUND IS DESIGNED FOR INVESTORS WHO:

 - are investing for long-term goals that may include college or retirement

 - are willing to assume the risk of losing money in exchange for attractive
   potential long-term returns

 - are investing for capital appreciation

 - want to diversify their portfolios with a more aggressive stock fund

   THEY MAY NOT BE APPROPRIATE IF YOU:

 - are investing for a shorter time horizon

 - are uncomfortable with an investment that will fluctuate in value

 - are looking for income

   You should base your investment decision on your own goals, risk preferences
and time horizon.


     A WORD ABOUT RISK

   All investments involve some level of risk. Simply defined, risk is the
possibility that you will lose money or not make money.

   Principal risk factors for the fund are discussed below. Before you invest,
please make sure you understand the risks that apply to the fund. As with any
mutual fund, you could lose money over any period of time.

   Investments in the fund are not bank deposits and are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

MARKET RISK

   The market value of a security may move up and down, sometimes rapidly and
unpredictably. These fluctuations, which are often referred to as "volatility,"
may cause a security to be worth less than it was worth at an earlier time.
Market risk may affect a single issuer, industry, sector of the economy, or the
market as a whole. Market risk is common to most investments--including stocks
and bonds, and the mutual funds that invest in them.

START-UP AND OTHER SMALL COMPANIES

   Start-up and other small companies may have less-experienced management,
limited product lines, unproven track records or inadequate capital reserves.
Their securities may carry increased market, liquidity and other risks. Key
information about the company may be inaccurate or unavailable.

SPECIAL-SITUATION COMPANIES

   "Special situations" are unusual developments that affect a company's market
value. Examples include mergers, acquisitions and reorganizations. Securities of
special-situation companies may decline in value if the anticipated benefits of
the special situation do not materialize.


                              PERFORMANCE SUMMARY

The bar chart and the table below provide an indication of the risks of
investing in the fund. The bar chart shows you how the fund's performance has
varied from year to year for up to 10 years. The table compares the fund's
performance over time to that of a broadly based securities market index. As
with all mutual funds, past performance is not a prediction of the future.

                           UNDERSTANDING PERFORMANCE

   BTOTAL RETURN tells you how much an investment in the fund has changed in
    value over a given time period. It assumes that all dividends and capital
    gains (if any) were reinvested in additional shares. The change in value
    can be stated either as a cumulative return or as an average annual rate
    of return.

   BA CUMULATIVE TOTAL RETURN is the actual return of an investment for a
    specified period. The year-by-year total returns in the bar chart are
    examples of one-year cumulative total returns.

   BAn AVERAGE ANNUAL TOTAL RETURN applies to periods longer than one year.
    It smoothes out the variations in year-by-year performance to tell you
    what constant annual return would have produced the investment's actual
    cumulative return. This gives you an idea of an investment's annual
    contribution to your portfolio, assuming you held it for the entire
    period.

   BBecause of compounding, the average annual total returns in the table
    cannot be computed by averaging the returns in the bar chart.

                                    EXAMPLE

This example may help you compare the cost of investing in this fund with the
cost of investing in other mutual funds. Because it uses hypothetical
conditions, your actual costs may be higher or lower.

Assume you invest $10,000, the fund returns 5% annually, expense ratios remain
as listed in the first table on the opposite page (before fee waivers and
expense reimbursements or credits) and you close your account at the end of each
of the time periods shown. Based on these assumptions, your cost would be:



      ONE YEAR            THREE YEARS            FIVE YEARS            TEN YEARS

financial statements. It is available free upon request.


     GOAL AND STRATEGIES

   The Small Company Value II Fund seeks long-term capital appreciation. To
pursue this goal, it invests in equity securities of small U.S. value companies.
Current income is a secondary consideration in selecting portfolio investments.

   Value companies are companies whose earnings power or asset value does not
appear to be reflected in the current stock price. As a result, value companies
look underpriced according to financial measurements of their intrinsic worth or
business prospects. These measurements include price-to-earnings, price-to-book,
price-to-cash flow and debt-to-equity ratios. The portfolio managers determine
value based upon research and analysis, taking all relevant factors into
account.

   Under normal market conditions, the fund will invest at least 65% of assets
in equity securities of small U.S. companies. The fund considers a "small"
company to be one whose market capitalization is within the range of
capitalizations of companies in the Russell 2000 Index. As
of December 31, 2000, market capitalizations of Russell 2000 companies ranged
from approximately $4 million to $6.1 billion.

   Some companies may outgrow the definition of a small company after the fund
has purchased their securities. These companies continue to be considered small
for purposes of the fund's 65% minimum allocation to small-company equities. In
addition, the fund may invest in companies of any size once the 65% policy is
met. As a result, the fund's average market capitalization may sometimes exceed
that of the largest company in the Russell 2000 Index.
     PORTFOLIO INVESTMENTS

   The fund invests primarily in equity securities of small-capitalization value
companies. Equity holdings may consist of:

 - common and preferred stocks

 - securities convertible into common stocks

 - rights and warrants

   The fund may invest up to 10% of assets in foreign securities. To a limited
extent, it may also engage in other investment practices.
     RISK FACTORS

   The fund's principal risk factors are:

 - market risk

 - start-up and other small companies

 - special-situation companies

   The value of your investment generally will fluctuate in response to
stock-market movements.

   Different types of stocks (such as "growth" vs. "value" stocks) tend to shift
in and out of favor depending on market and economic conditions. Accordingly,
the fund's performance may sometimes be lower or higher than that of other types
of funds (such as those emphasizing growth stocks).

   Investing in start-up and other small companies may expose the fund to
increased market, liquidity and information risks. These risks are defined in
"More About Risk."

   Small companies are often involved in "special situations." Securities of
special-situation companies may decline in value and hurt the fund's performance
if the anticipated benefits of the special situation do not materialize. "More
About Risk" details certain other investment practices the fund may use. Please
read that section carefully before you invest.

                                MORE ABOUT RISK


     INTRODUCTION

   The fund's goal and principal strategies largely determine its risk profile.
You will find a concise description of the fund's risk profile in "Key Points."
The discussion of the fund contains more detailed information. This section
discusses other risks that may affect the fund.

   The fund may use certain investment practices that have higher risks
associated with them. However, the fund has limitations and policies designed to
reduce many of the risks. The "Certain Investment Practices" table describes
these practices and the limitations on their use.

     TYPES OF INVESTMENT RISK

   The following risks are referred to throughout this Prospectus.

   CORRELATION RISK The risk that changes in the value of a hedging instrument
will not match those of the investment being hedged.

   CREDIT RISK The issuer of a security or the counterparty to a contract may
default or otherwise become unable to honor a financial obligation.

   CURRENCY RISK Fluctuations in exchange rates between the U.S. dollar and
foreign currencies may negatively affect an investment. Adverse changes in
exchange rates may erode or reverse any gains produced by foreign-currency-
denominated investments and may widen any losses.

   EXPOSURE RISK The risk associated with investments (such as derivatives) or
practices (such as short selling) that increase the amount of money the fund
could gain or lose on an investment.

    - HEDGED Exposure risk could multiply losses generated by a derivative or
      practice used for hedging purposes. Such losses should be substantially
      offset by gains on the hedged investment. However, while hedging can
      reduce or eliminate losses, it can also reduce or eliminate gains.

    - SPECULATIVE To the extent that a derivative or practice is not used as a
      hedge, the fund is directly exposed to its risks. Gains or losses from
      speculative positions in a derivative may be much greater than the
      derivative's original cost. For example, potential losses
      from writing uncovered call options and from speculative short sales
      are unlimited.

   INFORMATION RISK Key information about an issuer, security or market may be
inaccurate or unavailable.

   INTEREST-RATE RISK Changes in interest rates may cause a decline in the
market value of an investment. With bonds and other fixed-income securities, a
rise in interest rates typically causes a fall in values, while a fall in
interest rates typically causes a rise in values.

   LIQUIDITY RISK Certain fund securities may be difficult or impossible to sell
at the time and the price that the fund would like. The fund may have to lower
the price, sell other securities instead or forego an investment opportunity.
Any of these could have a negative effect on fund management or performance.

   MARKET RISK The market value of a security may move up and down, sometimes
rapidly and unpredictably. These fluctuations, which are often referred to as
"volatility," may cause a security to be worth less than it was worth at an
earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. Market risk is common to most
investments--including stocks and bonds, and the mutual funds that invest in
them.

   OPERATIONAL RISK Some countries have less-developed securities markets (and
related transaction, registration and custody practices) that could subject the
fund to losses from fraud, negligence, delay or other actions.

   POLITICAL RISK Foreign governments may expropriate assets, impose capital or
currency controls, impose punitive taxes, or nationalize a company or industry.
Any of these actions could have a severe effect on security prices and impair
the fund's ability to bring its capital or income back to the U.S. Other
political risks include economic policy changes, social and political
instability, military action and war.

   VALUATION RISK The lack of an
active trading market may make it difficult to obtain an accurate price for a
fund security.

                               ABOUT YOUR ACCOUNT


     SHARE VALUATION

   The price of your shares is also referred to as their net asset value (NAV).

   The NAV is determined at the close of regular trading on the New York Stock
Exchange (NYSE) (usually 4 p.m. Eastern Time) each day the NYSE is open for
business. It is calculated by dividing the Advisor Class's total assets, less
its liabilities, by the number of Advisor Class shares outstanding.

   The fund values its securities based on market quotations when it calculates
its NAV. 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 obligations that will mature in 60 days or
less are valued on the basis of amortized cost, unless the Board of Directors
determines that using this method would not reflect an investment's value.

   Some fund securities may be listed on foreign exchanges that are open on days
(such as U.S. holidays) when the fund does not compute its prices. This could
cause the value of the fund's portfolio investments to be affected by trading on
days when you cannot buy or sell shares.

     ACCOUNT STATEMENTS

   In general, you will receive account statements or notices as follows:

 - after every transaction that affects your account balance (except for
   distribution reinvestments and automatic transactions)

 - after any changes of name or address of the registered owner(s)

 - otherwise, every calendar quarter

   You will also receive annual and semiannual financial reports.

     DISTRIBUTIONS

   As a fund investor, you will receive distributions.

   The fund may earn dividends from stocks and interest from bond, money-market
and other investments. These are passed along as dividend distributions. The
fund realizes capital gains whenever it sells securities for a higher price than
it paid for them. These are passed along as capital-gain distributions.

   The fund typically distributes dividends and capital gains annually, usually
in December.

   Most investors have their distributions reinvested in additional shares of
the same fund. Distributions will be reinvested unless you choose on your
account application to have a check for your distributions mailed to you or sent
by electronic transfer.

   Estimated year-end distribution information, including record and payment
dates, will be available late in the year at www.warburg.com or by calling
800-222-8977. Investors are encouraged to consider the potential tax
consequences of distributions prior to buying or selling shares of the fund.

     TAXES

   As with any investment, you should consider how your investment in the fund
will be taxed. If your account is not a tax-advantaged retirement account, you
should be especially aware of the following potential tax implications. Please
consult your tax professional concerning your own tax situation.

TAXES ON DISTRIBUTIONS
   As long as the fund continues to meet the requirements for being a
tax-qualified regulated investment company, it pays no federal income tax on the
earnings it distributes to shareholders.

   Distributions you receive from the fund, whether reinvested or taken in cash,
are generally considered taxable. Distributions from the fund's long-term
capital gains are taxed as long-term capital gains regardless of how long you
have held fund shares. Distributions from other sources (including the fund's
short-term capital gains) are generally taxed as ordinary income. The fund will
mostly make capital-gain distributions, which will be largely derived from the
fund's short-term or long-term capital gains.

   If you buy shares shortly before or on the "record date"--the date that
establishes you as the person to receive the upcoming distribution--you may
receive a portion of the money you just invested in the form of a taxable
distribution.

   The Form 1099-DIV that is mailed to you every January details your
distributions and their federal-tax category, including the portion taxable as
long-term capital gain.

TAXES ON TRANSACTIONS
   Any time you sell or exchange shares, it is considered a taxable event for
you. Depending on the purchase price and the sale price of the shares you sell
or exchange, you may have a gain or loss
on the transaction. You are responsible
for any tax liabilities generated by
your transactions.

shares to their clients and customers (or participants in the case of retirement
plans). These firms provide distribution, administrative and shareholder
services for fund shareholders. The fund has adopted a Rule 12b-1 shareholder-
servicing and distribution plan to compensate these firms for their services.
The current 12b-1 fee is .50% per annum of the fund's average daily net assets,
although under the 12b-1 plan the fund is authorized to pay up to .75%. CSAMSI,
CSAM or their affiliates may make additional payments out of their own resources
to firms offering Advisor Class shares for providing administration,
subaccounting, transfer agency and/or other services. Under certain
circumstances, the fund may reimburse a portion of these payments.

                                 BUYING SHARES

     OPENING AN ACCOUNT

   Your account application provides us with key information we need to set up
your account correctly. It also lets you authorize services that you may find
convenient in the future.

   If you need an application, call our Institutional Services Center to receive
one by mail or fax.

   You can make your initial investment by check or wire. The "By Wire" method
in the table enables you to buy shares on a particular day at that day's closing
NAV.

     BUYING AND SELLING SHARES

   The fund is open on those days when the NYSE is open, typically Monday
through Friday. If we receive your request in proper form by the close of the
NYSE (usually 4 p.m. ET), your transaction will be priced at that day's NAV. If
we receive it after that time, it will be priced at the next business day's NAV.

FINANCIAL-SERVICES FIRMS

   You can buy and sell fund shares through a variety of financial-services
firms such as banks, brokers and financial advisors. The fund has authorized
these firms (and other intermediaries that the firms may designate) to accept
orders. When an authorized firm or its designee has received your order, it is
considered received by the fund and will be priced at the next-computed NAV.

   Financial-services firms may charge transaction fees or other fees that you
could avoid by investing directly with the fund. Please read their program
materials for any special provisions or additional service features that may
apply to your investment. Certain features of the fund, such as the minimum
initial or subsequent investment amounts, may be modified.

     ADDING TO AN ACCOUNT

   You can add to your account in a variety of ways, as shown in the table. If
you want to use Automated Clearing House (ACH) transfer, be sure to complete the
"ACH on Demand" section of the Advisor Class account application.

     INVESTMENT CHECKS

   Checks should be made payable in U.S. dollars to Warburg Pincus Advisor
Funds. Unfortunately, we cannot accept "starter" checks that do not have your
name pre-printed on them. We also cannot accept checks payable to you or to
another party and endorsed to the order of Warburg Pincus Advisor Funds. These
types of checks may be returned to you and your purchase order may not be
processed.

     SELLING SHARES IN WRITING

   Some circumstances require a written sell order, along with a signature
guarantee. These include:

 - accounts whose address of record has been changed within the past 30 days

 - redemptions in certain large accounts (other than by exchange)

 - requests to send the proceeds to a different payee or address than on record

 - shares represented by certificates, which must be returned with your sell
  order

   A signature guarantee helps protect against fraud. You can obtain one from
most banks or securities dealers, but not from a notary public.

     RECENTLY PURCHASED SHARES

   For fund shares purchased other than by bank wire, bank check, U.S. Treasury
check, certified check or money order, the fund will delay payment of your cash
redemption proceeds until check or other purchase payment clears, which
generally takes up to 10 calendar days from the day of purchase. At any time

during this period, you may exchange into another fund.

                              SHAREHOLDER SERVICES

     AUTOMATIC SERVICES

   Buying or selling shares automatically is easy with the services described
below. You can set up most of these services with your account application or by
calling our Institutional Services Center.

AUTOMATIC MONTHLY INVESTMENT PLAN

   For making automatic investments from a designated bank account.

AUTOMATIC WITHDRAWAL PLAN

   For making automatic monthly, quarterly, semiannual or annual withdrawals.

     STATEMENTS AND REPORTS

   The fund produces financial reports, which include among other things a list
of the fund's portfolio holdings, semiannually and updates its prospectus
annually. The fund generally does not hold shareholder meetings. To reduce
expenses by eliminating duplicate mailings to the same address, the fund may
choose to mail only one report, prospectus, proxy statement or information
statement, as applicable, to your household, even if more than one person in the
household has an account with the fund. Please call 800-222-8977 if you would
like to receive additional reports, prospectuses or proxy statements.

     TRANSFERS/GIFTS TO MINORS

   Depending on state laws, you can set up a custodial account under the Uniform
Transfers-to-Minors Act (UTMA) or the Uniform Gifts-to-Minors Act (UGMA). Please
consult your tax professional about these types of accounts.

     ACCOUNT CHANGES

   Call our Institutional Services Center to update your account records
whenever you change your address. The Institutional Services Center can also
help you change your account information or privileges.


                                 OTHER POLICIES

     TRANSACTION DETAILS

   You are entitled to capital-gain and earned-dividend distributions as soon as
your purchase order is executed.

   Your purchase order will be canceled and you may be liable for losses or fees
incurred by the fund if:

 - your investment check or ACH transfer does not clear

 - you place a telephone order by 4 p.m. ET and we do not receive your wire that
   day

   If you wire money without first calling our Institutional Services Center to
place an order, and your wire arrives after the close of regular trading on the
NYSE, then your order will not be executed until the end of the next business
day. In the meantime, your payment will be held uninvested. Your bank or other
financial-services firm may charge a fee to send or receive wire transfers.

   While we monitor telephone-servicing resources carefully, during periods of
significant economic or market change it may be difficult to place orders by
telephone.

   Uncashed redemption or distribution checks do not earn interest.
     SPECIAL SITUATIONS

   The fund reserves the right to:

 - refuse any purchase or exchange request, including those from any person or
   group who, in the fund's view, is likely to engage in excessive trading

 - change or discontinue its exchange privilege after 30 days' notice to current
   investors, or temporarily suspend this privilege during unusual market
   conditions

 - impose minimum investment amounts after 15 days' notice to current investors
   of any increases

 - charge a wire-redemption fee

 - make a "redemption in kind"--payment in portfolio securities rather than
   cash--for certain large redemption amounts that could hurt fund operations

 - suspend redemptions or postpone payment dates as permitted by the Investment
   Company Act of 1940 (such as during periods other than weekends or holidays
   when the NYSE is closed or trading on the NYSE is restricted, or any other
   time that the SEC permits)

 - stop offering its shares for a period of time (such as when management
   believes that a substantial increase in assets could adversely affect it).
