[WARBURG PINCUS LOGO] PROSPECTUS Common Class February 28, 2001 WARBURG PINCUS EMERGING GROWTH FUND - WARBURG PINCUS SMALL COMPANY VALUE II FUND - WARBURG PINCUS SMALL COMPANY GROWTH FUND As with all mutual funds, the Securities and Exchange Commission has not approved these funds, nor has it passed upon the adequacy or accuracy of this Prospectus. It is a criminal offense to state otherwise. Warburg Pincus Funds are advised by Credit Suisse Asset Management, LLC. 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. - ------------------------------------------------------------------------------ ACQUIRED FUND ACQUIRING FUND - ------------------------------------------------------------------------------ Warburg Pincus Value Fund Credit Suisse Warburg Pincus Value Fund - ------------------------------------------------------------------------------ Warburg Pincus Small Company Credit Suisse Warburg Pincus Small Value Fund Company Value 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.

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.

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. INVESTOR EXPENSES FEES AND FUND EXPENSES This table describes the fees and expenses you may bear as a shareholder. Annual fund operating expense figures are for the fiscal year ended October 31, 2000.

The Annual Report includes the auditor's report, along with the fund's financial statements. It is available free upon request. 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. PORTFOLIO MANAGEMENT Elizabeth B. Dater and Stephen J. Lurito manage the fund's investment portfolio.

The Common Class shares' operating expense ratio after reflecting these arrangements were 1.17% for the year ended October 31, 2000, and 1.22%, 1.22%, 1.21% and 1.27% for the years ending 1999, 1998, 1997 and 1996, respectively. 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 read that section carefully before you invest. PORTFOLIO MANAGEMENT Roger W.

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 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.

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. YEAR-BY-YEAR TOTAL RETURNS YEAR ENDED 12/31: 1996 1997 1998 1999 2000 SMALL COMPANY VALUE II FUND................................. 57.00% 17.77% - 7.22% 12.09% 14.80% Best quarter: 15.97% (Q3 97) Worst quarter: -21.21% (Q3 98) Inception date: 12/29/95 SMALL COMPANY VALUE II FUND ---------------------- 1996 57.00 1997 17.77 1998 -14.80 1999 7.22 2000 12.09 AVERAGE ANNUAL TOTAL RETURNS ONE YEAR FIVE YEARS TEN YEARS LIFE OF INCEPTION PERIOD ENDED 12/31/00: 2000 1996-2000 1991-2000 FUND DATE SMALL COMPANY VALUE II FUND 12.09% 13.63% NA 13.59% 12/29/95 RUSSELL 2000 INDEX* -3.02% 10.32% NA 10.32% * 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 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. INVESTOR EXPENSES FEES AND FUND EXPENSES This table describes the fees and expenses you may bear as a shareholder. Annual fund operating expense figures are for the fiscal year ended October 31, 2000. SHAREHOLDER FEES (paid directly from your investment) Sales charge "load" on purchases NONE Deferred sales charge "load" NONE Sales charge "load" on reinvested distributions NONE Redemption fees NONE Exchange fees NONE ANNUAL FUND OPERATING EXPENSES (deducted from fund assets) Management fee 1.00% Distribution and service (12b-1) fee .50% Other expenses .74% TOTAL ANNUAL FUND OPERATING EXPENSES* 2.24% *Actual fees and expenses for the fiscal year ended October 31, 2000 are shown below. Fee waivers and expense reimbursements or credits reduced expenses during 2000, but may be discontinued at any time. EXPENSES AFTER WAIVERS AND REIMBURSEMENTS Management fee .84% Distribution and service (12b-1) fee .50% Other expenses .65% ----- TOTAL ANNUAL FUND OPERATING EXPENSES 1.99% 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 $227 $700 $1,200 $2,575 THE FUND IN DETAIL THE MANAGEMENT FIRM CREDIT SUISSE ASSET MANAGEMENT, LLC 466 Lexington Ave. New York, NY 10017 - Investment adviser for the fund - Responsible for managing the fund's assets according to its goal and strategies. - A member of Credit Suisse Asset Management, the institutional asset management and mutual fund arm of Credit Suisse Group (Credit Suisse), one of the world's leading banks - Credit Suisse Asset Management companies manage approximately $94 billion in the U.S. and $298 billion globally - Credit Suisse Asset Management has offices in 14 countries, including SEC-registered offices in New York and London; other offices (such as those in Budapest, Frankfurt, Milan, Moscow, Paris, Prague, Sydney, Tokyo, Warsaw and Zurich) are not registered with the U.S. Securities and Exchange Commission For easier reading, Credit Suisse Asset Management, LLC will be referred to as "CSAM" or "we" throughout this Prospectus. MULTI-CLASS STRUCTURE The fund offers two classes of shares, Common and Advisor. This Prospectus offers the Advisor Class of shares, which are sold through financial-services firms. The Common Class of the fund is described in a separate prospectus. FUND INFORMATION KEY A concise description of the fund begins on the next page.

Percentages of fund assets are based on total assets unless indicated otherwise. PORTFOLIO INVESTMENTS The primary types of securities in which the fund invests. Secondary investments are described in "More About Risk." RISK FACTORS The major risk factors associated with the fund. Additional risk factors are included in "More About Risk." PORTFOLIO MANAGEMENT The individuals designated by the investment adviser to handle the fund's day-to-day management. INVESTOR EXPENSES Actual fund expenses for the 2000 fiscal year. Future expenses may be higher or lower. - MANAGEMENT FEE The fee paid to the investment adviser for providing investment advice to the fund. Expressed as a percentage of average net assets after waivers. - DISTRIBUTION AND SERVICE (12B-1) FEES Fees paid by the fund to the distributor for making shares of the fund available to you. Expressed as a percentage of average net assets. - OTHER EXPENSES Fees paid by the fund for items such as administration, transfer agency, custody, auditing, legal and registration fees and miscellaneous expenses.

Portfolio turnover may also result in capital-gain distributions that could raise your income-tax liability. The Annual Report includes the auditor's report, along with the fund's 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. PORTFOLIO MANAGEMENT Roger W. Vogel and Richard Hanlon co-manage the fund's investment portfolio. You can find out more about them in "Meet the Managers."

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. OTHER INFORMATION ABOUT THE DISTRIBUTOR Credit Suisse Asset Management Securities, Inc. (CSAMSI), a wholly owned subsidiary of CSAM, is responsible for: - making the fund available to you - account servicing and maintenance - other administrative services related to sale of the Advisor Class Certain institutions and financial-services firms may offer Advisor Class 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.

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.

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).
