The Fund seeks to achieve its objective by investing in companies that offer long-term capital appreciation. The Fund invests in common stock, securities convertible into common stock and other equity securities of well-known and established companies. The Fund takes a long-term view of each stock it buys, holding each company until its long-term growth potential no longer meets the Fund's requirements. Generally, the Fund attempts to identify companies with growth rates that will exceed that of the S&P 500 Index. The Credit Suisse Warburg Pincus Blue Chip Fund is "sector neutral." This means that its investments are allocated to industries in proportion to the sector allocation of the S&P 500 Index, with the exception of the electric and the gas utilities sectors. In the opinion of the Adviser, this strategy enables the Fund to properly diversify its portfolio within the most important and central realm of the U.S. equity universe. The Fund may also make an investment to earn income when its Adviser believes that it will not compromise the investment objective. To achieve this objective, the Fund may invest up to 35% of the value of its assets in investment-grade fixed income securities, including bonds, debentures, notes, asset and mortgage-backed securities and money market instruments such as commercial paper and bankers' acceptances and other financial instruments. The Fund may also invest in non-U.S. securities. Like any investment, an investment in the Credit Suisse Warburg Pincus Blue Chip Fund is subject to risk and you could lose money. While investments are selected that Credit Suisse Asset Management, LLC ("CSAM" or the "Adviser") believes will experience long-term appreciation, their value could decline. The Fund is subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1, 5 and 10 years compare to those of the S&P 500 Composite Index, which is a broad measure of market performance. The Fund's past performance is not necessarily an indication of how it will perform in the future.

THE CREDIT SUISSE WARBURG PINCUS VALUE FUND The Credit Suisse Warburg Pincus Value Fund's investment objective is long-term capital appreciation and continuity of income. The Fund seeks to achieve its objective by investing in dividend paying common stock and by diversifying its investments among different industries and different companies. Securities are selected on the basis of their investment merit and their potential for appreciation in value and/or income, with a focus on stability. The Adviser identifies companies that it believes are undervalued and waits for the market to discover that value. A portion of the Fund may be invested in debt securities that are of investment-grade quality, U.S. Government securities and money market instruments. The Fund may also invest in securities of non-U.S. based issuers or issuers that do business principally outside of the U.S., which we refer to as non-U.S. securities. There is no fixed percentage of the Fund's assets that must be invested in any particular type of security. Like any investment, an investment in the Credit Suisse Warburg Pincus Value Fund is subject to risk and you could lose money. While the Fund seeks investments that will appreciate in value and/or provide income, the Adviser could select securities that will decline in value and provide no income. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1, 5 and 10 years compare to those of the S&P 500 Composite Index, which is a broad measure of market performance.

Prior to the date of this prospectus, the Fund had not yet offered Advisor Class shares. Therefore, the Fund does not yet have a full calendar year of performance information for these classes. * The since inception (February 28, 1996) average annual total return for Class B shares for the period ending December 31, 2000 was 16.51%. ** The since inception (April 30, 1999) average annual total return for Class D shares for the period ending December 31, 2000 was 7.17%. *** The S&P 500 -Registered Trademark- is the Standard & Poor's Composite Index of 500 Stocks, a widely recognized, unmanaged index of common stock prices. The returns for the S&P 500 do not include any sales charges, fees or other expenses. THE CREDIT SUISSE WARBURG PINCUS SMALL COMPANY VALUE FUND The Credit Suisse Warburg Pincus Small Company Value Fund's investment objective is a high level of growth of capital. The Fund seeks to achieve its objective by investing in common stock and other equity securities of "small-cap" companies that appear to be undervalued. Companies with market capitalizations of $2 billion or less at the time of purchase are considered to be small-cap companies. This Fund's investment objective causes it to be riskier than other funds and you could lose money. While the Fund seeks investments that provide a high level of growth of capital, they may decline in value. You should not invest in this Fund if your principal objective is assured income or capital preservation. Investments in small-cap companies often involve greater risks than investments in larger, more established companies. Small-cap companies may have less management experience, fewer financial resources, and limited product diversification, all of which may increase risks. The frequency and trading volume for securities of small-cap companies are substantially less than for larger companies. This can result in greater and more abrupt price fluctuations and can cause small-cap stocks to be less liquid than securities of larger companies. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1, 5 and 10 years compare to those of the Russell 2000 Index, which is a broad measure of market performance. The Fund's past performance is not necessarily an indication of how it will perform in the future.

SEE "RECENT DEVELOPMENTS" FOR ADDITIONAL INFORMATION. The Credit Suisse Warburg Pincus Strategic Growth Fund's investment objective is long-term growth of capital. The Fund seeks to achieve this objective by investing in equity securities of a limited number of large, carefully selected companies that the Adviser believes will achieve superior growth. The Fund intends to hold securities of approximately 50-60 companies, which may fluctuate depending on the Adviser's view of market conditions. The Fund seeks to achieve superior performance as compared to other U.S. domestic growth funds. Like any investment, an investment in the Credit Suisse Warburg Pincus Strategic Growth Fund is subject to risk, and you could lose money. While the Adviser believes that the investments it selects will experience long-term appreciation, their value could decline. Growth companies are typically characterized by higher price-to-earnings and price-to-book ratios, lower dividend yields, greater volatility, and higher historical and predicted earnings. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. Because the Fund normally invests in a smaller number of securities than many other equity funds, an investment in this Fund has the risk that changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund's net asset value. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the highest and lowest quarterly returns for the Fund's first full calendar year and how the annual returns for 1 year and from inception compare to those of the S&P 500 Barra Index, which is a broad measure of market performance. The Fund's past performance is not necessarily an indication of how it will perform in the future. CALENDAR YEAR TOTAL RETURNS [BAR CHART] 2000 -16.00% The annual return referenced in the bar chart is for the calendar year ended December 31 and does not include sales charges. If sales charges were included, the annual return would be lower than shown. During the 1-year period shown in the bar chart for Common Class shares, the highest return for a quarter was 8.79% (quarter ending 3/31/00) and the lowest return for a quarter was -18.18% (quarter ending 12/31/00). 2000 was the first full calendar year of operations. 7 AVERAGE ANNUAL TOTAL RETURNS - -------------------------------------------------------------------------------------------------- (FOR THE PERIODS ENDING DECEMBER 31, 2000) PAST YEAR FROM INCEPTION ON 11/18/99 - -------------------------------------------------------------------------------------------------- STRATEGIC GROWTH FUND COMMON CLASS (15.93)% (7.33)% - -------------------------------------------------------------------------------------------------- S&P 500 BARRA INDEX* (22.08)% (15.35)% - -------------------------------------------------------------------------------------------------- Common Class shares are not subject to a sales charge.

Therefore, the Fund does not have a full calendar year of performance for these shares. * The S&P 500 Barra Index is comprised of those companies within the S&P 500 Index with higher ratios of market price to book value than other companies within the S&P 500 Index. The returns for the S&P 500 Barra Index do not include any sales charges, fees or other expenses. THE CREDIT SUISSE WARBURG PINCUS TECHNOLOGY FUND The Credit Suisse Warburg Pincus Technology Fund's investment objective is growth of capital. The Fund seeks to achieve this objective by investing in a broad number of industries that comprise the U.S. domestic technology sector. Under normal market conditions, the Fund invests at least 65% of its assets in technology companies. The Fund seeks to create a blend of stocks in companies that include, but are not limited to, the computer hardware, computer software, electronics, semiconductor, semiconductor capital equipment, telecommunication equipment, telecommunication services, and internet industries. Like any investment, an investment in the Credit Suisse Warburg Pincus Technology Fund is subject to risk and you could lose money. While the Fund seeks investments that will appreciate in value, the Adviser could select securities that will decline in value and provide no income. Technology stocks, especially those of smaller, less-seasoned companies tend to be more volatile than the overall stock market. When stock prices fall, you should expect the value of your investment to fall as well, possibly to a greater extent than the decline in equity markets generally. The fact that the Fund concentrates in a single sector increases risk and volatility as compared to more diverse funds. This is because factors that affect that sector are likely to directly affect the Fund's performance, both negatively and positively. Even if the overall direction of equity prices is upward, if technology stocks are headed lower, Fund performance could be adversely affected. For example, technology companies could be hurt by such factors as market saturation, price competition, and the advent of competing technologies. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the highest and lowest quarterly returns for the Fund's first full calendar year and how the annual returns for 1 year and from inception compare to those of the Chase H & Q Technology Index, which is a broad measure of market performance.

SEE "RECENT DEVELOPMENTS" FOR ADDITIONAL INFORMATION. The Credit Suisse Warburg Pincus Developing Markets Fund's investment objective is to provide long-term growth of capital by primarily investing in common stocks and other equity securities of companies from developing countries. The Fund seeks to achieve its objective by investing in securities of issuers in countries included in the Morgan Stanley Capital Index ("MSCI") Emerging Markets Free Index. The Fund's investment approach is to seek to minimize country and sector risk by maintaining country and sector neutrality, with weightings close to those of the MSCI Emerging Markets Free Index. This Fund's investment objective causes it to be riskier than other mutual funds and you could lose money. While the Fund seeks investments that provide a high level of growth of capital, they may decline in value. The Fund invests primarily in non-U.S. securities (securities of non-U.S. based issuers or issuers that do business principally outside the United States) of issuers in developing markets. Investments in non-U.S. securities present additional risks including greater price volatility and a lack of liquidity. Investments in developing markets present further risks because they tend to be smaller, less mature and less stable than investments in developed markets. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes in interest and foreign exchange rates. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1 and 5 years and from inception compare to those of the MSCI Emerging Markets Free Index, which is a broad measure of market performance.

THE CREDIT SUISSE WARBURG PINCUS INTERNATIONAL EQUITY II FUND The Credit Suisse Warburg Pincus International Equity II Fund's investment objective is long-term growth of capital by investing in equity securities from established non-U.S. markets. The Fund seeks to achieve this objective by focusing on investment selection based primarily on the recommendations of CSFB International Research. The Fund invests in securities of issuers in the developed countries of Europe, Australia and the Far East ("EAFE"), using disciplined, quantitative methods in its attempt to minimize country, industry and financial risks. The Fund is country and sector neutral and will seek to maintain its weightings close to those of the MSCI EAFE Index. Like any investment, an investment in the Fund is subject to risk and you could lose money. While the Fund selects investments that the Adviser believes will appreciate in value, those securities could decline in value and provide no income. The Fund invests primarily in non-U.S. securities (securities of non-U.S. based issuers or issuers that do business principally outside the United States). Investments in non-U.S. securities present additional risks including greater price volatility and a lack of liquidity. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes in interest (generally increases) and foreign exchange rates. These and other factors could adversely affect your investment.

CREDIT SUISSE WARBURG PINCUS FIXED INCOME FUNDS THE CREDIT SUISSE WARBURG PINCUS FIXED INCOME II FUND THE BOARD OF TRUSTEES OF THE FUND HAS APPROVED, SUBJECT TO SHAREHOLDER APPROVAL, AT A MEETING SCHEDULED FOR MARCH 23, 2001, THE TRANSFER OF ALL OF THE ASSETS AND LIABILITIES OF THE FUND IN EXCHANGE FOR SHARES OF THE WARBURG PINCUS CREDIT SUISSE WARBURG PINCUS FIXED INCOME FUND, A SIMILAR FUND IN THE WARBURG PINCUS FAMILY OF FUNDS. SEE "RECENT DEVELOPMENTS" FOR ADDITIONAL INFORMATION. The Credit Suisse Warburg Pincus Fixed Income II Fund's investment objective is to provide as high a level of total return as is consistent with capital preservation by investing principally in debt securities, including, without limitation, convertible and non-convertible debt securities of foreign and domestic companies, including both well-known and established and new and lesser-known companies. The Fund seeks to achieve its objective by investing primarily in a diversified portfolio of high-grade intermediate-term corporate bonds and U.S. Government securities, as well as in commercial paper and obligations issued or guaranteed by national or state banks. In addition, the Adviser actively manages the maturities of the securities in the portfolio in response to the Adviser's anticipation of the movement of interest rates and relative yields. The Fund seeks to limit risk by selecting investment-grade debt securities. While the Fund seeks investments that will satisfy its investment objective, the investments could decline in value and you could lose money. Concerns about an issuer's ability to repay its borrowings or to pay interest will adversely affect the value of its securities. The Fund is subject to risks that affect the bond markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. As interest rates rise, absent other factors, bond prices and the value of your investments will fall. The Fund is also subject to the risk that, in seeking to enhance total return, the Adviser will incorrectly forecast changes in interest rates or improperly assess the value of debt securities. These and other factors could adversely affect your investment. 11 The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1, 5 and 10 years compare to those of the Lehman Brothers Government/Corporate Intermediate Bond Index, which is a broad measure of market performance.

THE CREDIT SUISSE WARBURG PINCUS MUNICIPAL TRUST FUND THE BOARD OF TRUSTEES OF THE FUND HAS APPROVED, SUBJECT TO SHAREHOLDER APPROVAL, AT A MEETING SCHEDULED FOR MARCH 23, 2001, THE TRANSFER OF ALL OF THE ASSETS AND LIABILITIES OF THE FUND IN EXCHANGE FOR SHARES OF THE WARBURG, PINCUS MUNICIPAL BOND FUND, INC., A SIMILAR FUND IN THE WARBURG PINCUS FAMILY OF FUNDS. SEE "RECENT DEVELOPMENTS" FOR ADDITIONAL INFORMATION. The Credit Suisse Warburg Pincus Municipal Trust Fund's investment objective is to provide as high a level of total return as is consistent with capital preservation by investing principally in high-grade tax-exempt municipal securities. By high-grade tax-exempt municipal securities, we mean securities rated Aaa, Aa, A or MIG-1 by Moody's or AAA, AA, A or SP-1 by S&P. It is important to note that unlike most other municipal bond funds, the Fund's objective is not to provide current income that is exempt from federal and/or state income tax. The Fund seeks to achieve its objective by investing primarily in a diversified portfolio of high-grade, intermediate-term municipal securities. In addition, the Adviser actively manages the maturities of the securities in the portfolio in response to the Adviser's anticipation of the movement of interest rates and relative yields. Certain investments are selected that the Adviser believes are undervalued. The Fund attempts to limit risk by selecting investment-grade debt securities and by maintaining an average maturity of between five and ten years. 12 While the Fund seeks investments that will satisfy its investment objective, these investments could decline in value and you could lose money. Concerns about an issuer's ability to repay its borrowings or to pay interest will adversely affect the value of its securities. The Fund is also subject to the risk that, in seeking to enhance total return, the Adviser will incorrectly forecast changes in interest rates or improperly assess the value of municipal securities. Like all bond funds, this Fund is subject to risks that affect the bond markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. As interest rates rise, absent other factors, bond prices and the value of your investment will fall. The Fund is also subject to risks of investing in municipal securities. These risks include uncertainties regarding the securities' tax status, political and legislative changes and the rights of their holders. These and other factors could adversely affect your investment. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the rate of return from year to year and how annual returns for 1 and 5 years and from inception compare to those of The Lehman Brothers Seven Year Municipal Bond Index, which is a broad measure of market performance.

THE CREDIT SUISSE WARBURG PINCUS HIGH INCOME FUND The Credit Suisse Warburg Pincus High Income Fund's primary investment objective is to provide a high level of current income and a secondary objective is capital appreciation. The Fund seeks to achieve its objective by investing in fixed income securities of U.S. issuers that are rated below investment-grade quality or unrated fixed income securities deemed to be of comparable quality. Lower grade fixed income securities are commonly known as "junk bonds." This investment objective causes it to be riskier than other mutual funds and you could lose money. Investments in lower grade securities are subject to special risks, including greater price volatility and a greater risk of loss of principal and non-payment of interest. The market value of longer maturity debt securities, like those held 13 by the Fund, is more sensitive to interest rate changes than the market value of shorter maturity debt securities. The Fund is not recommended for investors whose principal objectives are assured income or capital preservation. This Fund is designed for investors willing to assume additional risk in return primarily for the potential for high current income and secondarily capital appreciation. The following chart and table illustrate the risk and the variability of the Fund's returns by showing the highest and lowest quarterly returns for the Fund's first full calendar year and how the annual returns for 1 year and from inception compare to those of Lipper Open-End High Yield Bond Fund Index, which is a broad measure of market performance.

THE CREDIT SUISSE WARBURG PINCUS MUNICIPAL MONEY FUND The Credit Suisse Warburg Pincus Municipal Money Fund's investment objective is maximum current income, consistent with liquidity and safety of principal, that is exempt from Federal income taxation to the extent described herein. The Fund seeks to achieve this objective by investing in municipal securities. The Fund earns income at current money market rates, and its yield generally reflects short-term interest rates which vary from day to day. Such municipal securities will have varying lengths of maturities but will generally have remaining maturities of one year or less. In general, securities with longer maturities are more vulnerable to price changes, although they may provide higher yields. Like any money market fund investment, this investment is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund seeks to preserve the value of your investment at $1.00 per share, however, it is possible to lose money by investing in the Fund. Because this Fund began operations in February, 1997, the first full calendar year of performance was 1998. The Fund's past performance is not necessarily an indication of how it will perform in the future. 14 CALENDAR YEAR TOTAL RETURNS [BAR CHART] 1998 3.00% 1999 2.00% 2000 3.00% During the 3-year period shown in the bar chart, the highest return for a quarter was 0.90% (quarter ending 12/31/00) and the lowest return for a quarter was 0.52% (quarter ending 3/31/99).

("CSAMSI") and PFPC, Inc. ("PFPC") began providing administrative services. Administrative services previously were provided by DLJAM and CSAM without charge to the Funds (although DLJAM, and then CSAM, were entitled to reimbursement from the Credit Suisse Warburg Pincus Opportunity Funds and the Credit Suisse Warburg Pincus Select Funds). Although these services are now provided for a total rate not to exceed .18% of average daily net assets, if the new investment advisory agreement is approved, CSAM will limit average annual expenses from the date of the acquisition of DLJ, November 3, 2000, until November 3, 2002 to the annualized levels previously paid by each Fund measured over the 60-day period ended on November 3, 2000. As a result, it is not anticipated that there will be any increase in the average annualized operating expense ratio of any of the Funds through November 3, 2002 due to the retention of new co-administrators. This limit is not reflected in the fee tables and examples above. PFPC continues to provide accounting services, but no longer pursuant to a separate agreement. ** Assumes reinvestment of all dividends and redemption at end of period. *** Assumes reinvestment of all dividends and no redemption at end of period. + Ten year figures assume conversion of Class B shares to Class A shares at the end of the eighth year following the date of purchase. ++ Shares purchased directly into a Money Fund will not be subject to a CDSC and therefore expenses paid will remain unaffected by redemption. (a) The Fund has adopted a Rule 12b-1 plan for the indicated classes of shares that allows the Fund to pay distribution fees for the sale and distribution of those classes of shares out of the assets applicable to those classes. Because these fees are paid out over time, they will increase the cost of your investment and may cost you more than paying other types of sales charges. A portion of the 12b-1 fee represents an asset-based sales charge. (b) The maximum amount payable for distributing these shares is .75 of 1% of the average daily net assets attributable to this Class. The Board of Trustees is currently limiting the amount payable to .50 of 1% of the average daily net assets attributable to the Class. (c) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Strategic Growth Fund to 1.19% for the Fund's Class A and Common Class shares and 1.94% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2002. (d) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Technology Fund to 1.14% per year for the Fund's Class D shares, 1.39% per year for the Fund's Class A and Common Class shares, and 2.14% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2002. 20 (e) The expense ratios for each class of shares of the Credit Suisse Warburg Pincus Developing Markets Fund and the Credit Suisse Warburg Pincus International Equity II Fund are higher than those paid by most other investment companies, but Credit Suisse Asset Management, LLC (as Adviser) believes that the fees are comparable to those paid by investment companies of similar investment orientation. On November 1, 2000, following the termination of the sub-adviser to the International Equity II Fund, the investment advisory fee was reduced to 1% of the average annual net assets of the Fund. (f) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Developing Markets Fund to 2.15% per year for the Fund's Class A and Common Class shares and 2.90% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2001. (g) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Fixed Income II Fund to .70% for the Fund's Class D shares, to .95% for the Fund's Class A and Common Class shares and to 1.70% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2001. (h) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Municipal Trust Fund to .95% per year for the Fund's Class A and Common Class shares and to 1.70% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2001. (i) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus High Income Fund to .85% per year for the Fund's Class D shares and 1.10% for the Fund's Class A shares and Common Class shares, and 1.85% for the Fund's Class B and Class C shares. This arrangement will remain in place at least until October 31, 2001. (j) The maximum allowable amount payable for distributing these shares is .40 of 1% of the average daily net assets of each Money Fund. The Board of Trustees has currently limited the amount payable to .25 of 1% of the average daily net assets of each Money Fund. (k) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus Municipal Money Fund to .90% per year. This arrangement will remain in place at least until October 31, 2001. (l) The Adviser has undertaken, in writing, to limit Total Expenses of the Credit Suisse Warburg Pincus U.S. Government Money Fund to .90% per year. This arrangement will remain in place at least until October 31, 2001. 21 RECENT DEVELOPMENTS The names of the DLJ Focus Funds, the DLJ Opportunity Funds and the DLJ Select Funds have changed to the Credit Suisse Warburg Pincus Capital Funds, the Credit Suisse Warburg Pincus Opportunity Funds and the Credit Suisse Warburg Pincus Select Funds, respectively. The names of each Fund have also changed, as indicated on the front page of this Prospectus. 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. ("DLJAM") were transferred to CSAM. As a result, and pursuant to approval by the Board of Trustees of each of the Credit Suisse Warburg Pincus Capital Funds, the Credit Suisse Warburg Pincus Opportunity Funds and the Credit Suisse Warburg Pincus Select Funds (each a "Fund" and collectively the "Funds"), CSAM has succeeded DLJAM as investment adviser to the Funds pursuant to interim advisory agreements (the "Interim Advisory Agreements"). The Interim Investment Advisory Agreements terminate at the earlier of April 2, 2001 and the approval by shareholders of the Funds of new investment advisory agreements with CSAM. To rationalize the management of the Funds and the Warburg Pincus family of funds managed by CSAM ("Warburg Pincus Funds"), CSAM has proposed, and the Board of Trustees of the relevant Funds have approved for submission to shareholders at meetings scheduled for March 23, 2001: (i) new investment advisory agreements with CSAM on the same economic terms as the Interim Advisory Agreements; (ii) the replacement of all the current Trustees of the Funds, other than Peter F. Krogh, with trustees of the Warburg Pincus Funds; and (iii) as more fully explained below, the combinations of certain series of the Funds (the "Acquired Funds") into similar funds within the Warburg Pincus Funds (the "Acquiring Funds"). On December 18, 2000, Credit Suisse Asset Management Securities, Inc. ("CSAMSI") became the distributor of the Funds. Effective February 1, 2001, the Funds retained CSAMSI and PFPC, Inc. ("PFPC") as co-administrators to each of the Funds for a total rate not to exceed .18% of each Funds' average daily net assets. DLJAM and then CSAM provided administrative services to the Funds without charge prior to February 1, 2001 (although DLJAM, and later CSAM, were entitled to reimbursement from the Funds of the Credit Suisse Warburg Pincus Select Funds and the Credit Suisse Warburg Pincus Opportunity Funds). However, CSAM has agreed to assume DLJAM's undertaking to limit total annual operating expenses until October 31, 2001, or October 31, 2002, as the case may be, and to limit average annual expenses from the date of the acquisition of DLJ, November 3, 2000, until November 3, 2002 to the annualized levels previously paid by each of the Funds measured over the 60-day period ended on the date of the acquisition of DLJ. Consequently, it is not anticipated that there will be any increase in the average annualized operating expense ratio of a Fund until November 3, 2002 as a result of the retention of new co-administrators. Further, accounting services previously provided by PFPC pursuant to a separate agreement will be provided by PFPC under its new co-administration agreement. Effective February 6, 2001, State Street Bank and Trust Company ("State Street") became the transfer agent for the Fund's Common Class (former Class R) shares. The Board has approved the retention of State Street as transfer agent for the Fund's other classes of shares. MERGERS. The Board of Trustees for each of the Acquired Funds listed below has approved, subject to shareholder approval, the transfer to the Acquiring Fund listed below of all of the assets and liabilities of the Acquired Fund in exchange for shares of the Acquiring Fund. ACQUIRED FUND ACQUIRING FUND ------------- -------------- Credit Suisse Warburg Pincus Fixed Income II Fund Warburg Pincus Fixed Income Fund Credit Suisse Warburg Pincus Municipal Trust Fund Warburg, Pincus Municipal Bond Fund, Inc. Credit Suisse Warburg Pincus Developing Markets Fund Warburg, Pincus Emerging Markets Fund, Inc. Credit Suisse Warburg Pincus Strategic Growth Fund Warburg, Pincus Focus Fund, Inc. Each of the Acquiring Funds has an investment objective and strategies substantially similar to the investment objective and strategies of the corresponding Acquired Fund. Shareholders of each Acquired Fund would receive on a tax-free basis shares of the relevant Acquiring Fund with the same net asset value as their shares of the Acquired Fund. The investment advisory fees of the Acquiring Funds would in each case be the same as the relevant 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 annualized expense ratio of each Acquired 22 Fund would not increase above its expense ratio for the 60-day period prior to consummation of the acquisitions. Each acquisition would be consummated promptly after receipt of shareholder approval. If an acquisition of an Acquired Fund is not approved, such Fund will continue to engage in business as a series of the Fund and the Board of the Acquired Fund will consider other possible courses of action available to it, including resubmitting the proposal to shareholders. The Board of Trustees of the Credit Suisse Warburg Pincus Capital Funds has approved the transfer of all of the assets and liabilities of the Warburg, Pincus Small Company Value II Fund, Inc. and the Warburg, Pincus Value II Fund, Inc. in exchange for shares of the Credit Suisse Warburg Pincus Small Company Value Fund and the Credit Suisse Warburg Pincus Value Fund, respectively. These acquisitions are subject to the approval of shareholders of the relevant Warburg, Pincus Fund and, if approved, are expected to be consummated in early June, 2001. 23 PURCHASE INFORMATION Shares of the Credit Suisse Warburg Pincus Municipal Money Fund and the Credit Suisse Warburg Pincus U.S. Government Money Fund (the "Money Funds") or Class A, Class B or Class C shares of the other Funds may be purchased directly by using the Share Purchase Application found in this Prospectus, or through CSAMSI, the Funds' distributor, or by contacting your securities dealer. Common Class shares of the Funds may be purchased directly by using the application available at the Shareholder Service Center or downloaded from WWW.WARBURG.COM. See "How to Buy and Sell Shares -- 2. For Common Class Shares." Common Class shares may also be purchased through a variety of financial services firms such as banks, brokers and financial advisors. Advisor Class Shares of the Credit Suisse Warburg Pincus Value Fund are available for purchase through certain eligible institutions and financial services firms and not by individual investors directly. The minimum initial investment in each Fund is $1,000 ($2,000 for Common Class shares). The minimum for additional investments is $25 ($50 for Common Class shares). These minimums are waived for certain types of accounts. Share certificates will not be issued for full or fractional shares of the Funds. Further information can be obtained from Credit Suisse Warburg Pincus Funds at the address and telephone number shown on the back cover of this Prospectus. See "How to Buy and Sell Shares" and "Other Shareholder Services." The Funds, except the Money Funds, offer Class A, Class B, Class C and Common Class shares. The Credit Suisse Warburg Pincus Blue Chip Fund, Credit Suisse Warburg Pincus Value Fund, Credit Suisse Warburg Pincus Small Company Value Fund, Credit Suisse Warburg Pincus Technology Fund, Credit Suisse Warburg Pincus International Equity II Fund, Credit Suisse Warburg Pincus Fixed Income II Fund and Credit Suisse Warburg Pincus High Income Fund also offer Class D shares. The Credit Suisse Warburg Pincus Value Fund also offers Advisor Class shares. Class A shares may be purchased at the net asset value per share of the Fund plus an initial sales charge imposed at the time of purchase and may be subject to a contingent deferred sales charge ("CDSC") in cases where the initial sales charge was not applied because of the size of the purchase. Class B shares may be purchased at the net asset value per share, but are subject to a CDSC upon redemption. The CDSC applicable to Class B shares declines from 4% for redemptions made during the first year of purchase to zero after four years. Class C shares may be purchased at the net asset value per share, but are subject to a 1% CDSC if redeemed within the first year of purchase. Common Class shares may be purchased at the net asset value per share without any initial sales charge or CDSC. Advisor Class shares may be purchased without any initial sales charge or CDSC. Class D shares are offered without any initial sales charge or CDSC to employees of Credit Suisse First Boston ("CSFB") and its subsidiaries that are eligible to participate in the Employee Savings and Retirement Plan of Credit Suisse First Boston, certain investment advisory or brokerage clients of CSAM or its affiliates, and certain employee benefit plans for employees of CSAM or its affiliates. CSFB employees should contact the CSFB Hotline at 1-800-588-6200 concerning how to purchase Class D shares. See "How to Buy and Sell Shares." Shares of the Money Funds may be purchased at a price equal to the net asset value per share of each Money Fund, which is expected to be $1.00 per share. See "Net Asset Value" in the side-bar included on this page. The Credit Suisse Warburg Pincus Blue Chip Fund, the Credit Suisse Warburg Pincus Value Fund, the Credit Suisse Warburg Pincus Small Company Value Fund, the Credit Suisse Warburg Pincus Fixed Income II Fund and the Credit Suisse Warburg Pincus Municipal Trust Fund are each a series of the Credit Suisse Warburg Pincus Capital Funds. The Credit Suisse Warburg Pincus International Equity II Fund, the Credit Suisse Warburg Pincus Developing Markets Fund, the Credit Suisse Warburg Pincus High Income Fund, the Credit Suisse Warburg Pincus Municipal Money Fund and the Credit Suisse Warburg Pincus U.S. Government Money Fund are each a series of the Credit Suisse Warburg Pincus Opportunity Funds. The Credit Suisse Warburg Pincus Strategic Growth Fund and the Credit Suisse Warburg Pincus Technology Fund are each a series of the Credit Suisse Warburg Pincus Select Funds. The Credit Suisse Warburg Pincus Opportunity Funds, Credit Suisse Warburg Pincus Capital Funds, and Credit Suisse Warburg Pincus Select Funds are different legal entities and are separately offering their Funds through this Prospectus. Based on the advice of counsel, the Funds believe that the potential liability of each Fund with respect to the disclosure in this Prospectus extends only to the disclosure relating to that Fund. 24 NET ASSET VALUE: Net asset value per share (or "NAV") is determined separately for each class by taking the total assets of each class of a Fund and subtracting its total liabilities and then dividing the difference by the total number of shares outstanding in each class. The NAV is determined at the close of the New York Stock Exchange each day that the New York Stock Exchange is open for trading. The price at which a purchase or redemption is effected is based on the next calculation of NAV after the order is placed. For the Money Funds, the NAV is expected to be maintained at a constant $1.00 per share, although this price is not guaranteed. For purposes of computing NAV, the securities in each Money Fund's portfolio are valued at amortized cost, which minimizes the effect of changes in a security's market value and helps maintain a stable $1.00 per share price. However, there is a risk that we will sell a security for a price that is higher or lower than amortized cost. Such an event could have an effect on our ability to maintain an NAV of $1.00 per share. In calculating the NAV of the Credit Suisse Warburg Pincus Funds, except the Money Funds, each Fund's investments are valued at their current market value determined on the basis of market quotations or, if such quotations are not readily available, such other method as the Trustees of the applicable Fund believe in good faith would accurately reflect their fair value. The investment objectives and policies of each Fund are set forth below. There can be, of course, no assurance that any Fund will achieve its investment objective. The Funds' investment objectives are fundamental policies that cannot be changed without the approval of the shareholders of the applicable Fund. The Board of Trustees of a Fund may change non-fundamental policies without shareholder approval. 25 CREDIT SUISSE WARBURG PINCUS FUNDS' INVESTMENT OBJECTIVES AND POLICIES CREDIT SUISSE WARBURG PINCUS BLUE CHIP FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Blue Chip Fund is long-term capital appreciation. Investments are made based on their potential for long-term capital appreciation. The Credit Suisse Warburg Pincus Blue Chip Fund may make an investment to earn income when, in the opinion of the Adviser, such an investment will not compromise the Credit Suisse Warburg Pincus Blue Chip Fund's investment objective. STRATEGY: The Credit Suisse Warburg Pincus Blue Chip Fund invests in common stock, securities convertible into common stock and other equity securities (e.g., preferred stock and interests in master limited partnerships). It invests primarily in well-known and established companies (generally, companies in operation for more than three years). The Fund may occasionally invest in new and unseasoned companies which, in the opinion of the Adviser, have the potential for long-term capital appreciation. The Adviser applies extensive research that has been conducted primarily by research analysts employed by Credit Suisse First Boston on the growth prospects of stocks that are considered for the Fund's portfolio. Target companies normally have market capitalizations of at least $1 billion at the time of purchase. Generally, the Adviser attempts to identify companies with growth rates that will exceed that of the S&P 500 Index. The Credit Suisse Warburg Pincus Blue Chip Fund is "sector neutral." This means that its investments are allocated to industries in proportion to the sector allocation of the S&P 500 Index, with the exception of the electric and the gas utilities sectors. Other factors considered in the selection of securities include the economic and political outlook, the value of a particular security relative to another security, trends in the determinants of corporate profits, and management capability and practices. See "Risks for the Credit Suisse Warburg Pincus Blue Chip Fund and the Credit Suisse Warburg Pincus Value Fund." INVESTMENTS: Under normal circumstances, the Credit Suisse Warburg Pincus Blue Chip Fund invests at least 65% of its total assets in equity securities of companies that the Adviser believes have above-average long-term capital appreciation potential. For temporary defensive purposes, the Credit Suisse Warburg Pincus Blue Chip Fund may invest in investment-grade short-term fixed-income securities, enter into repurchase agreements and hold cash. A temporary defensive position could affect the Fund's ability to achieve its investment objective. In addition, the Fund may invest in equity securities selected on a basis other than the potential for long-term capital appreciation. The Fund may invest up to 35% of the value of its assets in investment-grade fixed-income securities, including bonds, debentures, notes, asset and mortgage-backed securities and money market instruments such as commercial paper and bankers'-acceptances and other financial instruments. The Fund may invest in both listed and unlisted securities and may also: - invest up to 10% of the value of its total assets in non-U.S. securities; - invest no more than 10% of its net assets in restricted securities or other instruments with no ready market; - invest up to 5% of its total assets in warrants; and - attempt to minimize the effect of a market decline on the value of its securities, subject to market conditions, by writing covered call options on securities or stock indices. See "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS VALUE FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Value Fund is long-term capital appreciation and continuity of income. STRATEGY: The Credit Suisse Warburg Pincus Value Fund pursues its investment objective by investing principally in dividend-paying common stock and by diversifying its investments among different industries and companies. Securities are selected based on the Adviser's evaluation of their investment merit and their potential for appreciation in value and/or income. The selection of securities on the basis of their capital appreciation or income potential does not ensure against possible loss in value. INVESTMENTS: The Credit Suisse Warburg Pincus Value Fund invests in common stock, preferred stock and securities convertible into common stock. The Credit Suisse Warburg Pincus Value Fund may invest in debt securities that are of investment-grade quality at the time of purchase (including bonds, debentures, notes and asset 26 and mortgage-backed securities), U.S. government securities, municipal securities (including general and special obligation securities and industrial revenue bonds) and money market instruments. See "Additional Information on Investment Policies and Risks -- Mortgage and Asset-Backed Securities and Investment-Grade Debt Securities." There is no fixed proportion of the Credit Suisse Warburg Pincus Value Fund's assets that must be invested in particular types of securities. The percentage of assets invested in various types of securities may be changed from time to time by the Adviser. The Credit Suisse Warburg Pincus Value Fund invests in both listed and unlisted securities. The Credit Suisse Warburg Pincus Value Fund may invest in non-U.S. securities and restricted securities. To minimize the effect of a market decline in the value of its securities, the Fund may, depending on market conditions, write covered call options on securities or stock indices. The Fund may invest up to 10% of its assets in non-U.S. securities and up to 10% of its assets in restricted securities. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." RISKS FOR THE CREDIT SUISSE WARBURG PINCUS BLUE CHIP FUND AND THE CREDIT SUISSE WARBURG PINCUS VALUE FUND: Like any investment, an investment in the Credit Suisse Warburg Pincus Blue Chip Fund or Credit Suisse Warburg Pincus Value Fund is subject to risk and you could lose money. While the Funds seek investments that will appreciate in value and/or provide income, the value of the securities could decline and provide no income. The Funds are subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes in interest rates (generally increases). If the value of equity markets in general declines, you can expect the value of your investment in the Funds to decline, possibly to a greater extent than the decline in equity markets generally. The Credit Suisse Warburg Pincus Blue Chip Fund may invest in new and unseasoned companies. Stocks of these companies tend to be more volatile than stocks of larger and more established companies. In addition, because stocks are selected on the basis of their appreciation potential, they tend to be more risky than many investments that provide current income. The Credit Suisse Warburg Pincus Value Fund may invest in debt securities. Debt securities are subject to risks that the issuer will not repay its borrowings or pay interest. They are also subject to the risk of declines in value because of increases in interest rates and decreases in the credit quality of the issuer. The Credit Suisse Warburg Pincus Blue Chip Fund and the Credit Suisse Warburg Pincus Value Fund may each invest in unlisted securities. Investments in unlisted securities may be less liquid and more volatile than investments in listed securities and could result in losses to the Funds if they had to be sold quickly. The Credit Suisse Warburg Pincus Blue Chip Fund and the Credit Suisse Warburg Pincus Value Fund may each invest in non-U.S. securities. Non-U.S. securities carry the same risks as securities of U.S. companies and the added risks of being traded in less liquid markets than U.S. securities. Non-U.S. securities are also issued by companies that are not subject to U.S. reporting requirements and involve political systems, economies and markets that may not be as developed as in the U.S. See "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS SMALL COMPANY VALUE FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Small Company Value Fund is a high level of growth of capital. The Credit Suisse Warburg Pincus Small Company Value Fund is not intended for investors whose principal objective is assured income or preservation of capital. STRATEGY: The Credit Suisse Warburg Pincus Small Company Value Fund invests primarily in common stock and may also invest in securities convertible into common stock, preferred stock, other equity securities, bonds or other debt securities as described below. Under normal market conditions, at least 65% of the Fund's assets are invested in equity securities of small market capitalization companies. "Small-cap" companies, for purposes of this Fund, are considered to be companies with market capitalizations of $2 billion or less at the time of purchase. If the market capitalization of a small-cap company in which the Fund has invested increases to a level above $2 billion, the investment adviser will continue to hold the securities of that company until the investment adviser determines that the company no longer has growth potential. 27 INVESTMENTS: The Credit Suisse Warburg Pincus Small Company Value Fund pursues its investment objective by employing a value-oriented investment approach. This means that the Adviser seeks securities that appear to be underpriced. The Adviser looks for stocks issued by companies with proven management, consistent earnings, sound finances and strong potential for market growth. By investing in such companies, the Credit Suisse Warburg Pincus Small Company Value Fund tries to enhance its potential for appreciation and limit the risk of decline in the value of its portfolio. The Credit Suisse Warburg Pincus Small Company Value Fund focuses on the fundamentals of each small-cap company instead of trying to anticipate what changes might occur in the stock market, the economy, or the political environment. This approach differs from that used by many other funds investing in small-cap company stocks. Those other funds often buy stocks of companies they believe will have above-average earnings growth, based on anticipated future developments. In contrast, the Credit Suisse Warburg Pincus Small Company Value Fund's securities are generally selected with the belief that they are currently undervalued based on existing conditions and that their earning power or franchise value does not appear to be reflected in their current stock price. To further reduce risk, the Credit Suisse Warburg Pincus Small Company Value Fund diversifies its holdings among many companies and industries. The Adviser also considers whether a company has an established presence in its industry, a product or market niche and whether management owns a significant stake in the company. The Credit Suisse Warburg Pincus Small Company Value Fund may also invest in special situation companies. A special situation company is a company whose value may increase within a reasonable period of time solely by reason of a development particularly or uniquely applicable to that company. The securities of these companies may be affected by particular developments unrelated to business conditions generally. These investments may fluctuate without relation to general market trends. In general, the principal risk associated with investing in special situation companies is the potential decline in the value of these securities likely to occur if the anticipated development fails to take place. Examples of special situation companies are companies that are being reorganized or merged, have unusual new products, enjoy particular tax advantages, or acquire new management. The Credit Suisse Warburg Pincus Small Company Value Fund invests primarily in common stock. It may also invest in securities convertible into common stock, preferred stock, investment-grade debt securities (including bonds, debentures, notes, asset and mortgage-backed securities), U.S. Government Securities, municipal securities (including general and special obligation securities and industrial revenue bonds), money market instruments (such as commercial paper and bankers' acceptances) and other financial instruments. The Credit Suisse Warburg Pincus Small Company Value Fund may also invest in unlisted securities and securities traded in the over-the-counter markets. The Credit Suisse Warburg Pincus Small Company Value Fund may allocate a larger percentage of its assets to unlisted securities than would a typical large company mutual fund. The Credit Suisse Warburg Pincus Small Company Value Fund may also: - purchase or sell options on securities and on indices to seek to enhance return or hedge its portfolio; - purchase or sell financial futures contracts and options thereon for hedging and risk management purposes; - invest up to 20% of total assets in non-U.S. securities; - invest up to 5% of total assets in rights or warrants; and - invest not more than 10% of net assets in instruments having no ready market. However, the Fund does not invest in restricted securities. RISKS FOR THE CREDIT SUISSE WARBURG PINCUS SMALL COMPANY VALUE FUND: The investment objective for the Credit Suisse Warburg Pincus Small Company Value Fund causes it to be riskier than other funds and you could lose money. While it seeks investments that will provide a high level of growth of capital, they may decline in value. You should not invest in the Credit Suisse Warburg Pincus Small Company Value Fund if your principal objective is assured income or capital preservation. While smaller companies generally have the potential for rapid growth, they often involve greater risks than investments in larger, more established companies. Small companies may have less management experience, fewer financial resources, and limited product diversification. In addition, in many instances the frequency and trading volume for securities of smaller companies are substantially less than those of larger companies, causing such securities to be subject to greater and more abrupt price fluctuations and to be less liquid than securities of larger companies. When making large sales of portfolio securities, it may be necessary for the Credit Suisse Warburg Pincus Small Company Value Fund to sell such 28 securities at discounts from quoted prices or to execute a series of small sales over an extended period of time. These factors cause an investment in the Credit Suisse Warburg Pincus Small Company Value Fund to be riskier than an investment in a typical "large company" mutual fund. The Credit Suisse Warburg Pincus Small Company Value Fund also is subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes in interest rates. These factors also could adversely affect an investment in the Fund. If the value of equity markets in general declines, the value of your investment in the Credit Suisse Warburg Pincus Small Company Value Fund could also decline, possibly to a greater extent than the decline in equity markets generally. The Credit Suisse Warburg Pincus Small Company Value Fund may invest in various types of debt securities. Debt securities are subject to the risk that the issuer will not repay its borrowings or pay interest. They are also subject to the risk of declines in value because of increases in interest rates and decreases in the perceived credit quality of the issuer. The Fund may also invest in unlisted securities. Investments in unlisted securities may be less liquid and more volatile than investments in listed securities and could result in losses if they had to be sold quickly. The Fund may also invest in non-U.S. securities. Not only do non-U.S. securities carry the same risks as securities of U.S. companies, they also have the added risks of generally being traded in less liquid markets than U.S. securities, involve political systems, economies and markets that may not be as developed as in the U.S. and may be issued by companies that are not subject to reporting requirements that are as rigorous as those imposed on U.S. issuers. The Fund also may invest in options, warrants and financial futures contracts. Selecting options, warrants and financial futures contracts involves determinations as to how a particular security, index, interest rate, or currency will change. If the Adviser is wrong in its prediction, the Fund could lose money. In addition, such instruments may not be available, or if available, may be too expensive to utilize. See "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS STRATEGIC GROWTH FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Strategic Growth Fund is long-term growth of capital. Investments are made based on their potential for superior growth. STRATEGY: The Fund seeks to achieve this objective by investing in equity securities of a limited number of large, carefully selected companies that the Adviser believes will achieve superior growth. Unlike most equity funds, the Fund focuses on a relatively small number of intensely researched companies. The Fund seeks to achieve superior performance as compared to other U.S. domestic growth funds. The Adviser applies extensive research that has been conducted primarily by research analysts employed by Credit Suisse First Boston on the growth prospects of stocks that are considered for the Fund's portfolio. Unlike many equity funds, the Credit Suisse Warburg Pincus Strategic Growth Fund seeks to limit the number of Fund holdings to companies that offer the highest potential for capital appreciation. The Fund intends to hold securities of approximately 50-60 companies, which may fluctuate depending on the Adviser's view of market conditions. Growth companies tend to be concentrated in the technology, health care, consumer, financial, telecommunications and commercial services sectors. By emphasizing Credit Suisse First Boston research in the portfolio stock selection, this Fund will try to deliver superior performance as compared to the U.S. domestic growth fund peer universe. Other factors considered in the selection of securities include the economic and political outlook, the value of a particular security relative to another security, trends in the determinants of corporate profits, and management capability and practices. See "Additional Information on Investment Policies and Risks." INVESTMENTS: Under normal circumstances, the Credit Suisse Warburg Pincus Strategic Growth Fund invests at least 85% of its total assets in equity securities in U.S. companies that the Adviser believes have above-average long-term capital appreciation potential. The Adviser expects the average market capitalization of companies in the portfolio to be in the range of companies that are included in the Standard & Poor's 500 Index. The Fund may invest in both listed and unlisted securities and may also: - invest up to 10% of the value of its total assets in non-U.S. securities; - invest no more than 15% of its net assets in illiquid securities; 29 - invest up to 5% of its total assets in warrants; - attempt to minimize the effect of a market decline on the value of its securities, subject to market conditions, by writing covered call options on securities or stock indices. See "Additional Information on Investment Policies and Risks"; and - invest in investment-grade fixed income securities, including bonds, debentures, notes and money market instruments such as commercial paper and bankers acceptances and other financial instruments. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS TECHNOLOGY FUND GOAL: The Credit Suisse Warburg Pincus Technology Fund's investment objective is growth of capital. STRATEGY: The Credit Suisse Warburg Pincus Technology Fund seeks to achieve this objective by investing in a broad number of industries that comprise the U.S. domestic technology sector. Under normal market conditions, the Fund invests at least 65% of its assets in technology companies. The Fund seeks to create a blend of stocks in companies that include the computer hardware, computer software, electronics, semiconductor, semiconductor capital equipment, telecommunication equipment, telecommunication services and internet industries. Stock selection reflects a growth approach and is based on fundamental research that assesses a company's prospects for above-average earnings. The research applied by the Adviser is conducted primarily by research analysts employed by Credit Suisse First Boston. In addition, the Adviser also obtains research from other investment firms. INVESTMENTS: The Credit Suisse Warburg Pincus Technology Fund invests in common stock, preferred stock and securities convertible into common stock. The Fund will normally invest 80% of its assets in securities of companies principally engaged in offering, developing products, processes or services that will provide technological advances and improvements. The types of companies include computer hardware, computer software, electronics, semiconductor, telecommunication equipment, telecommunication services and internet industries. The Fund may invest in listed and unlisted securities, well-known and established companies and in new and unseasoned companies. The Fund will not invest more than 25% of its total assets in any one industry. The Fund may also: - attempt to minimize the effect of a market decline on the value of its securities, subject to market conditions, by writing covered call options on securities or stock indices; - invest up to 10% of its assets in non-U.S. securities; - invest up to 15% of its net assets in illiquid securities; and - invest in investment-grade fixed income securities, including bonds, debentures, notes and money market instruments such as commercial paper and bankers-acceptances and other financial instruments. RISKS FOR THE CREDIT SUISSE WARBURG PINCUS TECHNOLOGY FUND AND THE CREDIT SUISSE WARBURG PINCUS STRATEGIC GROWTH FUND: Like any investment, an investment in the Credit Suisse Warburg Pincus Technology Fund or Credit Suisse Warburg Pincus Strategic Growth Fund is subject to risk and you could lose money. While the Funds seek investments that will appreciate in value, the value of the securities could decline and provide no income. The Funds are subject to market risks that affect equity securities markets in general, such as general economic conditions and adverse changes in interest rates (generally increases). If the value of equity markets in general declines, you can expect the value of your investment in the Funds to decline, possibly to a greater extent than the decline in equity markets generally. The Funds are also subject to investment risk, which is the possibility that the returns from a specific type of stock will perform worse than the overall stock market or other market sectors. Other general risks include the following: The Credit Suisse Warburg Pincus Technology Fund invests in technology companies. The fact that the Fund concentrates in a single sector increases risk and volatility as compared to a fund with a more diversified portfolio. This is because factors that affect that sector are likely to directly affect the Fund's performance, both negatively and positively. Even if the overall direction of equity prices is upward, if technology stocks are headed lower, Fund performance could be adversely affected. Certain factors or market conditions that affect technology companies could have an impact on the Fund's net asset value and performance. For example, companies in the rapidly 30 changing technology sector often face unusually high price volatility, both in terms of gains and losses. Products or services that at first appear promising may not prove commercially successful or may become obsolete quickly. Earnings disappointments could also result in sharp price declines. In addition, stocks of small, less seasoned companies, tend to be more volatile than the overall market. The Credit Suisse Warburg Pincus Strategic Growth Fund will limit the number of companies in its portfolio. As a result, changes in the value of one security are more likely to have a greater effect on the Fund's net asset value than other U.S. domestic growth funds with more diversified portfolios. In addition, each Fund may from time to time take temporary defensive positions that are inconsistent with a Fund's investment strategies in attempting to respond to adverse market conditions. If a Fund takes a temporary defensive position, the Fund may not achieve its investment objective. THE CREDIT SUISSE WARBURG PINCUS INTERNATIONAL FUNDS CREDIT SUISSE WARBURG PINCUS DEVELOPING MARKETS FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Developing Markets Fund is long-term growth of capital by investing primarily in common stocks and other equity securities of companies from developing countries. Under normal market conditions, the Fund invests at least 65% of its assets in equity securities of developing countries. STRATEGY: The Credit Suisse Warburg Pincus Developing Markets Fund seeks to achieve this objective by investing in securities of issuers in countries included in the Morgan Stanley Capital Index ("MSCI") Emerging Markets Free Index. The Fund's investment approach is to seek to minimize country and sector risk by maintaining country and sector neutrality, with weightings close to those of the MSCI Emerging Markets Free Index. INVESTMENTS: Equity securities include common and preferred stock, warrants, rights or options that are convertible into common stock, debt securities that are convertible into common stock, depositary receipts for those securities and other classes of stock that may exist. The Fund may purchase non-U.S. securities in the form of sponsored or unsponsored depositary receipts or other securities representing underlying shares of non-U.S. issuers. The Fund may purchase a limited amount of restricted or otherwise illiquid securities. The Fund may enter into forward foreign currency exchange contracts to attempt to protect the value of its assets against future changes in the level of currency exchange rates. The Fund may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging, return enhancement and risk management purposes. The Fund may purchase and sell financial futures contracts and related options, without limitation, for bona fide hedging purposes. Subject to the foregoing, the value of all financial futures contracts sold will not exceed the total market value of the Fund's portfolio. These futures contracts and related options will be on financial indices and foreign currencies or groups of foreign currencies. As used in this Prospectus, a company in a developing country is an entity for which either the principal securities trading market is in a developing country, it is organized under the laws in a developing country or it has its principal office in a developing country. The Fund invests primarily in countries represented within the MSCI Emerging Markets Free Index. Those countries currently include Argentina, Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Jordan, Korea, Malaysia, Mexico, Pakistan, Peru, Philippines, Poland, Russia, South Africa, Sri Lanka, Taiwan, Thailand, Turkey and Venezuela. The Fund generally does not invest more than 25% of its total assets in developing countries not represented within the MSCI Emerging Markets Free Index. RISKS FOR THE CREDIT SUISSE WARBURG PINCUS DEVELOPING MARKETS FUND: Like any investment, an investment in the Credit Suisse Warburg Pincus Developing Markets Fund is subject to risk and you could lose money. While the Fund selects investments that the Fund believes will experience long-term appreciation, their value could decline. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. There are certain risks involved in investing in non-U.S. securities, in addition to the risks inherent in U.S. investments. These risks may include currency fluctuations, currency revaluations, adverse political and economic developments, currency exchange blockages, foreign governmental laws or restrictions, reduced public information concerning issuers, and the lack of uniform accounting, auditing and financial reporting standards and other regulatory practices and requirements comparable for domestic companies. 31 Furthermore, non-U.S. securities may be less liquid and more volatile than comparable U.S. securities. There is also a possibility of expropriation, nationalization, confiscatory taxation, and limitations on use or removal of funds or assets. Investments in non-U.S. securities may result in higher expenses due to currency conversions, brokerage commissions which generally are higher than U.S. commissions and the expense of maintaining securities with non-U.S. custodians. In addition to the general risks of investing in non-U.S. securities, characteristics of developing countries may affect certain investments, such as national policies that restrict foreign investment and the absence of developed legal structures governing private property and private and foreign investments. The typically small size of securities markets and the possibility of a low or nonexistent volume of trading in developing countries may also result in a lack of liquidity and substantial price volatility. You should be aware that investing in developing countries generally involves exposure to economic structures that are generally less diverse and mature, and to political systems with less stability than those of developed countries. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS INTERNATIONAL EQUITY II FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus International Equity II Fund is long-term growth of capital by investing primarily in equity securities from established non-U.S. markets. During normal market conditions, the Fund invests most of its assets in securities of issuers from at least three different countries outside the United States. The Fund may invest in securities of companies incorporated in the United States but having their principal activities and interests outside of the United States. STRATEGY: The Fund seeks to achieve this objective by focusing on stock selection based primarily on the recommendations of CSFB International Research. The Fund invests in the developed countries of Europe, Australia and the Far East ("EAFE"), using disciplined, quantitative methods in its attempt to minimize country, industry and financial risks. The Fund is country and sector neutral and seeks to maintain its weightings close to those of the MSCI-EAFE Index. Those countries currently include Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. INVESTMENTS: Equity securities include common and preferred stock, warrants, rights or options that are convertible into common stock, debt securities that are convertible into common stock, depositary receipts for those securities and other classes of stock that may exist. The Fund may purchase non-U.S. securities in the form of sponsored or unsponsored depositary receipts or other securities representing underlying shares of non-U.S. issuers. The Adviser anticipates that, subject to market conditions, depositary receipts may represent a substantial portion of the Fund's investments. This Fund may invest a limited amount of its assets in restricted or otherwise illiquid securities. The Fund may enter into forward foreign currency exchange contracts to protect the value of its assets against future changes in the level of currency exchange rates. The Fund may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging, return enhancement and risk management purposes. The Fund may purchase and sell financial futures contracts and related options, without limitation, for bona fide hedging purposes. Subject to the foregoing, the value of all financial futures contracts sold will not exceed the total market value of the Fund's portfolio. These futures contracts and related options will be on financial indices and foreign currencies or groups of foreign currencies. ADRS: ADRs are depositary receipts typically issued by a U.S. bank or trust company which evidence ownership of underlying securities issued by a non-U.S. corporation. EDRs and GDRs are depositary receipts typically issued by non-U.S. banks or trust companies, although they also may be issued by U.S. banks or trust companies, and evidence ownership of underlying securities issued by either a non-U.S. or a U.S. corporation. 32 RISKS FOR THE CREDIT SUISSE WARBURG PINCUS INTERNATIONAL EQUITY II FUND: Like any investment, an investment in the Credit Suisse Warburg Pincus International Equity II Fund is subject to risk and you could lose money. While the Fund selects investments the Fund believes will experience long-term appreciation, their value could decline. The Fund is also subject to risks that affect equity securities markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. There are certain risks involved in investing in non-U.S. securities, in addition to the risks inherent in U.S. investments. These risks may include currency fluctuations, currency revaluations, adverse political and economic developments, currency exchange blockages, foreign governmental laws or restrictions, reduced public information concerning issuers, and the lack of uniform accounting, auditing and financial reporting standards and other regulatory practices and requirements comparable for domestic companies. Furthermore, non-U.S. securities may be less liquid and more volatile than comparable U.S. securities. There is also a possibility of expropriation, nationalization, confiscatory taxation, and limitations on use or removal of funds or assets. Investments in non-U.S. securities may result in higher expenses due to currency conversions, brokerage commissions which generally are higher than U.S. commissions and the expense of maintaining securities with non-U.S. custodians. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." THE CREDIT SUISSE WARBURG PINCUS FIXED INCOME FUNDS CREDIT SUISSE WARBURG PINCUS FIXED INCOME II FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Fixed Income II Fund is to provide as high a level of total return as is consistent with capital preservation by investing principally in debt securities, including, without limitation, convertible and nonconvertible debt securities of domestic and foreign companies, including both well-known and established and new and lesser-known companies. Total return means the sum of net investment income (if any) and realized and unrealized gains less losses. Capital preservation means minimizing the risk of capital loss in a period of falling prices (rising interest rates) for debt securities. STRATEGY: The Fund invests in and holds debt securities that the Adviser believes will maximize total return at a level consistent with capital preservation. The average maturity of the Fund's portfolio is adjusted based on the Adviser's assessment of relative yields on debt securities and expectations of future interest rate patterns. A change in the price of a debt security generally is inversely related to market interest rates. This means that the value of the Fund's investments will tend to decrease during periods of rising interest rates and to increase during periods of falling rates. In general, as the average maturity of the portfolio increases, so does the potential volatility in share price. As a matter of fundamental policy, the Fund will invest at least 80% of the value of its total assets in debt securities. In normal circumstances, the Credit Suisse Warburg Pincus Fixed Income II Fund invests at least 65% of the value of its total assets in fixed income securities. However, the Fund may hold cash and short-term fixed income securities and may enter into repurchase agreements for temporary defensive purposes as determined by the Adviser without regard to the above limits. A temporary defensive position could affect the Fund's ability to achieve its investment objective. INVESTMENTS: The Credit Suisse Warburg Pincus Fixed Income II Fund may invest in bonds, including municipal bonds (taxable and tax-exempt) and other debt securities rated Aaa, Aa, A or MIG-1 by Moody's Investors Service, Inc. ("Moody's"), or AAA, AA, A or SP-1 by Standard & Poor's Ratings Group ("S&P"), U.S. Government Securities, obligations issued or guaranteed by national or state bank holding companies, and commercial paper rated Prime-1 by Moody's or A-1+ or A-1 by S&P. The Credit Suisse Warburg Pincus Fixed Income II Fund may also invest not more than 25% of its total assets in lower-rated debt securities that are not rated below BBB or SP-2 by S&P or Baa or MIG-2 by Moody's to the extent the Adviser views such investments as consistent with this Fund's investment objective. See "Additional Information on Investment Policies and Risks" for a description of securities rated BBB by S&P and Baa by Moody's. The Credit Suisse Warburg Pincus Fixed Income II Fund may enter into repurchase agreements, terminable within seven days or less, involving U.S. Treasury securities, with member banks of the Federal Reserve 33 System or primary dealers in U.S. Government Securities. The Credit Suisse Warburg Pincus Fixed Income II Fund may invest up to 10% of its assets in restricted securities and in instruments having no ready market value. CREDIT SUISSE WARBURG PINCUS MUNICIPAL TRUST FUND GOAL: The investment objective of the Credit Suisse Warburg Pincus Municipal Trust Fund is to provide as high a level of total return as is consistent with capital preservation by investing principally in high-grade tax-exempt municipal securities. This investment objective, unlike that of most other municipal bond funds, is NOT to provide current income exempt from federal and/or state income tax. Total return means the sum of net investment income and capital gains less capital losses. The Fund intends to distribute annually its net capital gains. Such distributions, if any, will be taxable to a shareholder as capital gain. See "Dividend and Distribution Information" and "Taxes." STRATEGY: The Credit Suisse Warburg Pincus Municipal Trust Fund attempts to maximize total return by actively managing the maturities of the bonds in its portfolio to reflect the Adviser's assessment of anticipated interest rate movements and relative yields. The Credit Suisse Warburg Pincus Municipal Trust Fund currently maintains an average maturity of between 5 and 10 years in order to help reduce the interest rate risk associated with investing in long-term bonds. However, the Fund may adjust this average maturity as the Adviser's views on interest rate movements change, shortening maturities in periods of rising interest rates and lengthening maturities in periods of falling interest rates. The Fund attempts to supplement total return by identifying and purchasing undervalued municipal securities. As with any fixed income investment, the success of these strategies depends upon the Adviser's ability to accurately forecast changes in interest rates and to assess the value of municipal securities. You should be aware that there are no assurances that the Fund's investment strategies will be successful. See "Risks for the Credit Suisse Warburg Pincus Fixed Income II Fund and the Credit Suisse Warburg Pincus Municipal Trust Fund." INVESTMENTS: The Credit Suisse Warburg Pincus Municipal Trust Fund seeks to achieve its objective by investing primarily in a diversified portfolio of high-grade, intermediate-term municipal securities. Municipal securities fall into two principal classes: bonds and notes, both of which may have fixed, variable or floating rates of interest. The Fund invests in tax-exempt municipal bonds and notes which are rated Aaa, Aa, A or MIG-1 by Moody's or AAA, AA, A or SP-1 by S&P. The Fund may also invest up to 25% of its total assets in lower-rated municipal securities to the extent the Adviser views such investments as consistent with this Fund's investment objective. See "Additional Information on Investment Policies and Risks -- Investment-Grade Debt Securities" for a description of securities rated BBB by S&P and Baa by Moody's. The Fund may also invest in unrated municipal securities when the Adviser believes they are of comparable quality to that of rated securities and are consistent with the Fund's objective and policies. Because a change in the market value of a debt security generally is inversely related to market interest rates, the market value of the Credit Suisse Warburg Pincus Municipal Trust Fund's investments will tend to decrease during periods of rising interest rates and to increase during periods of falling rates. In general, as the average maturity of the portfolio increases, so does the potential volatility in share price. Fluctuations in market value of the Credit Suisse Warburg Pincus Municipal Trust Fund's portfolio resulting from fluctuations in interest rates will generally be greater at times when the average maturity of the Credit Suisse Warburg Pincus Municipal Trust Fund's portfolio is longer. The Credit Suisse Warburg Pincus Municipal Trust Fund may enter into repurchase agreements terminable within seven days or less. The Fund may also invest in restricted securities, in instruments having no ready market value and municipal bonds that are subject to the alternative minimum tax. The Credit Suisse Warburg Pincus Municipal Trust Fund reserves the right to hold cash and short-term fixed income securities and to enter into repurchase agreements as necessary for temporary defensive or emergency purposes as determined by the Adviser, without regard for the above limitation. A temporary defensive position could affect the Fund's ability to achieve its investment objective. Dividends of the Credit Suisse Warburg Pincus Municipal Trust Fund will consist of income exempt from federal income tax, income subject to the federal alternative minimum tax ("AMT"), and taxable ordinary income and capital gains. See "Dividend and Distribution Information" and "Taxes." 34 RISKS FOR THE CREDIT SUISSE WARBURG PINCUS FIXED INCOME II FUND AND CREDIT SUISSE WARBURG PINCUS MUNICIPAL TRUST FUND: While these Funds seek investments that will satisfy their investment objectives, the Funds' investments could decline in value and you could lose money. Concerns about an issuer's ability to repay its borrowings or to pay interest will adversely affect the value of its securities. The Funds' Adviser seeks to limit this risk generally by selecting higher-quality debt securities. In addition, the Funds are subject to risks that affect the bond markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. Each Fund may invest in unlisted securities. Unlisted securities may be less liquid and more volatile than listed securities and could result in losses if they had to be sold quickly. The Credit Suisse Warburg Pincus Municipal Trust Fund is also subject to risks of investing in municipal securities. These risks include uncertainties regarding the tax status of a particular security, political and legislative changes and the rights of their holders. These factors could adversely affect your investment. HIGH QUALITY RATINGS: High Quality Ratings are Aaa, Aa, A or MIG-1 by Moody's, or AAA, AA, A or SP-1 by S&P. CREDIT SUISSE WARBURG PINCUS HIGH INCOME FUND GOAL: The Credit Suisse Warburg Pincus High Income Fund's primary investment objective is to provide a high level of current income and a secondary objective is capital appreciation. This Fund is not recommended for investors whose principal objective is assured income or capital preservation. STRATEGY: This Fund seeks to achieve its investment objectives by investing in fixed-income securities, including corporate bonds and notes, convertible securities and preferred stocks, that are rated in the lower rating categories of the established rating services (Baa or lower by Moody's and BBB or lower by S&P), or, if unrated, are of comparable quality. Securities rated Baa or lower by Moody's and BBB or lower by S&P are commonly known as "junk bonds." These bonds are considered by those rating agencies to have speculative characteristics. These bonds can be expected to provide higher yields. However these securities may be subject to greater market fluctuations and risk of loss of income and principal than lower yielding, higher-rated fixed-income securities. Investment in such high-yield securities entails relatively greater risk of loss of income and principal. INVESTMENTS: This Fund seeks to achieve its objective by investing primarily in a diversified portfolio of lower-rated fixed-income securities including convertible and non-convertible debt securities and preferred stock. The Fund may also hold assets in cash or cash equivalents. This Fund generally does not invest in common stocks, rights or other equity securities. From time to time, the Fund may acquire or hold such securities (if consistent with its objectives) when they are acquired in unit offerings with fixed-income securities or in connection with an actual or proposed conversion, exchange or restructuring of fixed-income securities. Selection and supervision by the Adviser of the Fund of investments in lower-rated fixed-income securities involves continuous analysis of individual issuers, general business conditions and other factors. The furnishing of these services does not, of course, guarantee successful results. The Adviser's analysis of issuers includes, among other things, historic and current financial conditions, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing, and current and anticipated results of operations. Analysis of general business conditions and other factors may include anticipated changes in economic activity and interest rates, the availability of new investment opportunities, and the economic outlook for specific industries. While the Adviser considers as one factor in its credit analysis the ratings assigned by the rating services, the Adviser performs its own independent credit analysis of issuers and consequently, the Credit Suisse Warburg Pincus High Income Fund may invest, without limit, in unrated securities. The Fund's ability to achieve its investment objective may depend on the Adviser's own credit analysis to a greater extent than the funds that invest in higher-rated securities. Although the Credit Suisse Warburg Pincus High Income Fund primarily invests in lower-rated securities, it will generally not invest in securities rated at the time of investment in the lowest rating categories (Ca or below for Moody's and CC or below for S&P). Securities which are subsequently downgraded may continue to be held and will be sold only if, in the judgment of the Adviser, it is advantageous to do so. 35 RISKS FOR THE CREDIT SUISSE WARBURG PINCUS HIGH INCOME FUND: While the Credit Suisse Warburg Pincus High Income Fund seeks investments that will satisfy its investment objective, the Fund's investments could decline in value and you could lose money. Concerns about an issuer's ability to repay its borrowings or to pay interest will adversely affect the value of its securities. The Fund is also subject to risks that affect the bond markets in general, such as general economic conditions and adverse changes (generally increases) in interest rates. The market value of longer maturity debt securities, like those held by the Fund, is more sensitive to interest rate changes than the market value of shorter maturity debt securities. In addition, the Fund's investments in lower grade securities will subject investors to greater risk than normally experienced in other fixed income securities. Lower grade securities are regarded as being predominantly speculative as to the issuer's ability to pay the principal and interest. Issuers of lower grade securities are more likely to experience financial stress in periods of economic downturn or rising interest rates. The issuer's ability to service its debt may be adversely affected by poor management, inability to meet business forecasts or unavailability of additional financing. There is a higher default rate with lower grade securities because they may be unsecured or subordinate to other securities of the issuer. There are fewer dealers in lower grade securities which may make the market for these securities less liquid and cause larger differences in prices quoted than that of higher-rated fixed income securities. In addition, the Fund may incur additional expense when it is required to seek recovery upon a default or restructuring. THE CREDIT SUISSE WARBURG PINCUS MONEY FUNDS CREDIT SUISSE WARBURG PINCUS MUNICIPAL MONEY FUND GOAL: The Credit Suisse Warburg Pincus Municipal Money Fund seeks maximum current income, consistent with liquidity and safety of principal, that is exempt from Federal income taxation to the extent described herein. STRATEGY: The Fund pursues its objectives by investing at least 80% of its total assets in municipal securities. One hundred percent of the securities the Fund invests in are high quality having remaining maturities of one year or less, although their maturities may extend to 397 days. The Fund reserves the right to lower the percentage of investments in municipal securities if economic or political conditions warrant. To increase the Fund's ability to reach its investment objectives, the dollar-weighted average maturity of its portfolio securities is always 90 days or less. In general, securities with longer maturities are more vulnerable to price changes, although they may provide higher yields. It is possible that a major change in interest rates or a default on the Credit Suisse Warburg Pincus Municipal Money Fund's investments could cause its net asset value per share to deviate from $1.00. INVESTMENTS: Normally, substantially all the Credit Suisse Warburg Pincus Municipal Money Fund's income will be exempt from Federal income taxation. Such income may be subject to state or local and/or Federal AMT income taxes. The Fund invests in municipal notes and short-term municipal bonds, which may have fixed, variable or floating rates of interest. Municipal securities with variable rates may include participation interests in industrial development bonds which may be backed by letters of credit from banking or other financial institutions. The letters of credit of any single institution in respect of all variable rate obligations will not cover more than the allowable percentage of the Credit Suisse Warburg Pincus Municipal Money Fund's total assets in accordance with Rule 2a-7 under the Investment Company Act of 1940, as amended ("1940 Act"). For a more complete discussion of Municipal Securities, see "Additional Information on Investment Policies and Risks -- Municipal Securities." All of the Fund's municipal securities at the time of purchase are rated within the two highest quality ratings of Moody's or S&P's, or judged by the Adviser to be of comparable quality. The Credit Suisse Warburg Pincus Municipal Money Fund may also invest without limitation in tax-exempt municipal securities subject to the AMT. See "Dividend and Distribution Information" and "Taxes." The Credit Suisse Warburg Pincus Municipal Money Fund may invest to a limited extent in stand-by commitments, delayed-delivery, when-issued securities and other illiquid securities. This Fund may also invest a small percentage of its net assets in municipal leases, which are leases or installment purchases used by state and local governments as a means to acquire property, equipment or facilities without involving debt issuance limitations. The Fund may from time to time invest in taxable securities including obligations of the U.S. Government and its agencies, high quality certificates of deposit and bankers' acceptances, prime commercial paper, and repurchase agreements. 36 CASH EQUIVALENTS: The International Funds may from time to time take a defensive position by holding all or a portion of the Fund in other types of securities, including commercial paper, bankers' acceptances, short-term debt securities (corporate and government) or government and high quality money market securities of U.S. and non-U.S. issuers, repurchase agreements, time deposits or cash (foreign currencies or U.S. dollars). The International Funds may also temporarily hold cash and invest in high quality foreign or domestic money market instruments with up to 35% of their assets, pending investment of proceeds from new sales of International Funds' shares or to meet ordinary daily cash needs. RISKS FOR THE CREDIT SUISSE WARBURG PINCUS MUNICIPAL MONEY FUND: Like any money market fund investment, this investment is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. This fund seeks to preserve the value of your investment at $1.00 per share; however, it is possible to lose money by investing in this Fund. To seek to reduce investment risk, the Credit Suisse Warburg Pincus Municipal Money Fund may not invest in the securities of any one issuer, (except the U.S. Government), in excess of the percentage of the Credit Suisse Warburg Pincus Municipal Money Fund's total assets allowed under Rule 2a-7 of the 1940 Act. The Credit Suisse Warburg Pincus Municipal Money Fund earns income at current money market rates and its yield varies from day to day and generally reflects current short-term interest rates and other market conditions. It is important to note that neither the Credit Suisse Warburg Pincus Municipal Money Fund nor its yield are insured or guaranteed by the U.S. Government. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." CREDIT SUISSE WARBURG PINCUS U.S. GOVERNMENT MONEY FUND GOAL: The Credit Suisse Warburg Pincus U.S. Government Money Fund seeks maximum current income, consistent with liquidity and safety of principal. STRATEGY: This Fund pursues its objectives by maintaining a portfolio of high quality money market securities, including the types described in the succeeding paragraph, which at the time of investment generally have remaining maturities of one year or less. Some maturities may extend to 397 days. The dollar weighted average maturity of the Credit Suisse Warburg Pincus U.S. Government Money Fund's portfolio securities will vary, but will always be 90 days or less. In general, securities with longer maturities are more vulnerable to price changes, although they may provide higher yields. It is possible that a major change in interest rates or a default on the Credit Suisse Warburg Pincus U.S. Government Money Fund's investments could cause its net asset value per share to deviate from $1.00. INVESTMENTS: The Fund invests in U.S. Government Securities, including issues of the U.S. Treasury, such as bills, certificates of indebtedness, notes and bonds, and issues of agencies and instrumentalities established under the authority of an act of Congress, including variable rate obligations such as floating rate notes. The Fund also invests in repurchase agreements that are collateralized in full each day by eligible mortgage related securities or the types of securities listed above. These agreements are entered into with "primary dealers" (as designated by the Federal Reserve Bank of New York) in U.S. Government Securities. This type of investment could create a loss to the Fund if, in the event of a dealer default, the proceeds from the sale of the collateral were less than the repurchase price. In addition, if the seller of repurchase agreements becomes insolvent, the Fund's right to dispose of the securities might be restricted. In addition to the investments listed, the Money Funds may take temporary defensive measures by holding other types of securities which are permitted by Rule 2a-7 of the 1940 Act. RISKS FOR THE CREDIT SUISSE WARBURG PINCUS U.S. GOVERNMENT MONEY FUND: Like any money market fund investment, this investment is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. This Fund seeks to preserve the value of your investment at $1.00 per share, however, it is possible to lose money by investing in this Fund. 37 The Credit Suisse Warburg Pincus U.S. Government Money Fund earns income at current money market rates and its yield will vary from day to day and generally reflects current short-term interest rates and other market conditions. It is important to note that neither the Credit Suisse Warburg Pincus U.S. Government Money Fund nor its yield is insured or guaranteed by the U.S. Government. TO MAINTAIN PORTFOLIO DIVERSIFICATION AND REDUCE INVESTMENT RISK, THE MONEY FUNDS DO NOT: (1) borrow money, except from banks on a temporary basis or through entering into reverse repurchase agreements to be used exclusively to facilitate the orderly maturation and sale of portfolio securities during any periods of abnormally heavy redemption requests (the borrowings are not used to purchase investments); or (2) pledge, hypothecate or in any manner transfer, as security for indebtedness, its assets, except to secure permitted borrowings. For additional information on the use, risks and costs of the above referenced policies and practices, see "Additional Information on Investment Policies and Risks." 38 ADDITIONAL INFORMATION ON INVESTMENT POLICIES AND RISKS The following general investment policies and risks supplement those set forth above for each Fund. EQUITY SECURITIES. "Equity securities" include common stock, preferred stock (including convertible preferred stock), bonds convertible into common or preferred stock, rights and warrants, equity interests in trusts and depositary receipts for equity securities. CONVERTIBLE SECURITIES. A "convertible security" is a bond or preferred stock which may be converted at a stated price within a specified period of time into a certain quantity of the common or preferred stock of the same or a different issuer. Convertible securities have characteristics of both bonds and equity securities. Like a bond, a convertible security tends to increase in market value when interest rates decline and tends to decrease in market value when interest rates rise. However, the price of a convertible security is also influenced by the market value of the underlying stock. The price of a convertible security tends to increase as the market value of the underlying stock rises, whereas it tends to decrease as the market value of the underlying stock declines. WARRANTS. A "warrant" gives the holder thereof the right to buy equity securities at a specific price during a specified period of time. Warrants tend to be more volatile than the underlying security, and if at a warrant's expiration date the security is trading at a price below the price set in the warrant, the warrant will expire worthless. Conversely, if at the expiration date the underlying security is trading at a price higher than the price set in the warrant, the holder of the warrant can acquire the security at a price below its market value. MORTGAGE-BACKED SECURITIES. Except for the Credit Suisse Warburg Pincus Municipal Trust Fund, the Credit Suisse Warburg Pincus Funds may invest in mortgage-backed securities. "Mortgage-backed securities" are securities that directly or indirectly represent a participation in, or are secured by and payable from mortgage loans on real property, including pass-through securities such as Ginnie Mae, Fannie Mae and Freddie Mac Certificates. The yield and credit characteristics of mortgage-backed securities differ in a number of ways from traditional fixed income securities. The major differences typically include more frequent interest and principal payments, usually monthly, and the possibility that prepayment of principal may be made at any time. Prepayment rates are influenced by changes in current interest rates and a variety of other factors. In general, changes in the rate of prepayment on a security will change the yield to maturity of that security. Under certain interest rate or prepayment rate scenarios, a Fund may fail to recoup fully its investment in such securities notwithstanding the credit quality of the issuers of such securities. Based on historic prepayment patterns, amounts available for reinvestment are likely to be greater during a period of declining interest rates and, thus, are likely to be reinvested at lower interest rates, than during a period of rising interest rates. Mortgage-backed securities may decrease in value as a result of increases in interest rates and may benefit less than other fixed income securities from declining interest rates because of the risk of prepayment. ASSET-BACKED SECURITIES. Except for the Credit Suisse Warburg Pincus Municipal Trust Fund, the Credit Suisse Warburg Pincus Funds may invest in asset-backed securities. "Asset-backed securities" have similar structural characteristics to mortgage-backed securities, but the underlying assets include assets such as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property and receivables from revolving credit agreements, rather than mortgage loans or interests in mortgage loans. Asset-backed securities present certain risks that are not present in mortgage-backed securities; primarily, these securities do not have the benefit of the same security interest in the related collateral. There is the possibility that recoveries of repossessed collateral may not, in some cases, be available to support payments on these securities. For example, in the event that the collateral underlying an asset-backed security must be disposed of, it may be difficult to convert that collateral into a stream of payments to be paid to the holders of the security. MUNICIPAL SECURITIES. "Municipal securities" are either bonds or notes. Municipal bonds, which are longer-term debt obligations meeting long-term capital needs, are either "general obligation" bonds or "revenue" bonds. Payment of principal and interest on general obligation bonds is secured by the issuing municipality's pledge of its full faith and credit and taxing power. Payment on revenue bonds is met from the revenues obtained from a certain facility, class of facilities, special excise or other tax, but not from general tax revenues. Variations on these two classifications exist, such as revenue bonds backed by a municipality's general taxing power, or general obligation bonds backed by limited taxing power. Municipal notes are short-term debt obligations generally maturing in one year or less meeting short-term capital needs and are also either "general obligation" or "revenue" debt securities. They include tax anticipation notes, revenue anticipation notes, bond anticipation notes, construction loan notes and tax-exempt commercial paper. 39 Municipal securities may have fixed, variable or floating rates of interest. Variable and floating rate securities pay interest at rates that are adjusted periodically, according to a specified formula, in order to minimize fluctuation in the value of the principal of the securities. A "variable" interest rate adjusts at predetermined intervals (e.g., daily, weekly, or monthly), while a "floating" interest rate adjusts whenever a specified benchmark rate (such as the bank prime lending rate) changes. The Credit Suisse Warburg Pincus Municipal Money Fund and Credit Suisse Warburg Pincus Municipal Trust Fund may invest in variable rate obligations. Such adjustments minimize changes in the market value of the obligation, and in the case of the Credit Suisse Warburg Pincus Municipal Money Fund enhances the ability of such Fund to maintain a stable $1.00 net asset value. See "Net Asset Value." INVESTMENT-GRADE DEBT SECURITIES. All of the Credit Suisse Warburg Pincus Funds may invest in debt securities of investment-grade quality. "Investment-grade debt securities" are debt securities rated in one of the four highest rating categories by a nationally recognized statistical rating organization, such as S&P or Moody's. Investment-grade debt securities may also include debt securities believed by the Adviser (on the basis of criteria believed by the Adviser to be comparable to that applied by such rating agencies) to be of comparable quality to debt securities so rated by the rating agencies. Debt securities rated Baa or higher by Moody's or BBB or higher by S&P are investment-grade securities. Securities rated BBB are regarded by S&P as having an adequate capacity to pay interest and repay principal; while such securities normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely, in the opinion of S&P, to lead to a weakened capacity to pay interest and repay principal for debt in this category than in higher rated categories. Securities rated Baa by Moody's are considered to be medium-grade obligations. These securities are neither highly protected nor poorly secured. The rating organization determines that interest payments and principal security appear to be adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. For a more complete description of Moody's and S&P's ratings, see the Appendix to the Statement of Additional Information of each of the Credit Suisse Warburg Pincus Funds. The investment-grade limitations referenced for each Fund are applicable at the time of initial investment and a Fund may determine to retain securities of issuers which have had their credit characteristics downgraded. REPURCHASE AGREEMENTS. The Credit Suisse Warburg Pincus Funds may enter into a repurchase agreement with member banks of the Federal Reserve System or "primary dealers" (as designated by the Federal Reserve Bank of New York) in such securities. Repurchase agreements permit a Fund to keep all of its assets at work while retaining "overnight" flexibility in pursuit of investments of a longer-term nature. The Adviser requires continual maintenance of collateral with a Fund's custodian in an amount equal to, or in excess of, the market value of the securities that are the subject of a repurchase agreement. In the event a counterparty defaults on its repurchase obligation, a Fund might suffer a loss to the extent that the proceeds from the sale of the collateral are less than the repurchase price. If the counterparty becomes the subject of bankruptcy proceedings, the Fund might be delayed in selling the collateral. NON-U.S. SECURITIES. All of the Credit Suisse Warburg Pincus Funds, except the Money Funds and the Credit Suisse Warburg Pincus Municipal Trust Fund, may invest in securities of issuers outside of the United States, which we refer to as "non-U.S. securities." There are additional risks involved in investing in non-U.S. securities. These risks include those resulting from fluctuations in currency exchange rates, revaluation of currencies, and the possible imposition of currency exchange blockages. In addition, there are risks associated with future adverse political and economic developments and a limited availability of public information concerning issuers. Non-U.S. issuers typically are subject to different accounting, auditing and financial reporting standards. Securities of many non-U.S. companies may be less liquid and their prices more volatile than those of domestic companies. There is the possibility of expropriation, nationalization, confiscatory taxation and limitations on the use or removal of Funds or other assets of a non-U.S. issuer, including the withholding of dividends. Non-U.S. securities may be subject to taxes imposed by foreign governments that would reduce the net yield on such securities. Investment in non-U.S. securities may result in higher expenses due to the cost of converting foreign currency into U.S. dollars, the payment of fixed brokerage commissions on foreign exchanges (which generally are higher than commissions on U.S. exchanges) and the expense of maintaining securities with non-U.S. custodians. 40 Investments in non-U.S. securities include securities issued by European issuers. On January 1, 1999, the countries participating in the European Monetary Union ("EMU") implemented a new currency unit, the Euro, which is reshaping financial markets, banking systems and monetary policies in Europe and other parts of the world. Although it is not possible to predict the eventual impact of the Euro implementation plan on the Funds, the transition to the Euro may change the economic environment and behavior of investors, particularly in European markets. Certain European investments may be subject to additional risks as a result of this conversion. These risks include adverse tax and accounting consequences, as well as difficulty in processing transactions. The Funds are aware of such potential problems and are coordinating ways to prevent or alleviate their adverse impact on the Funds. INVESTMENT COMPANIES. Certain Funds may invest a limited amount of their assets in shares of other investment companies. Investments in other mutual funds may involve the payment of substantial premiums above the value of such investment companies' portfolio securities. In addition, such investments are subject to limitations under the 1940 Act and market availability. Currently, the International Funds, the Credit Suisse Warburg Pincus Strategic Growth Fund, the Credit Suisse Warburg Pincus Technology Fund and the Credit Suisse Warburg Pincus Municipal Money Fund may invest in such investment companies if, in the judgment of the Adviser, the potential benefits of such investments justify the payment of any applicable premium or sales charge. As a shareholder in an investment company, these Funds would bear its ratable share of that investment company's expenses, including its advisory and administrative fees. At the same time shareholders of these Funds would continue to pay their own management fees and other expenses. OPTIONS. A call option is a contract that gives the holder the right to buy from the seller the security underlying the call option at a pre-determined price while a put option is a contract that gives the buyer the right to require the seller to purchase the security underlying the put option at a pre-determined price. The Credit Suisse Warburg Pincus Blue Chip Fund and the Credit Suisse Warburg Pincus Value Fund may write covered call options on individual securities or stock indices. For these Funds, this practice will only be used to minimize the effect of a market decline in the value of securities in their respective portfolios. We cannot guarantee that, should a Fund seek to enter into such transactions, it could do so at all or on terms that are acceptable. The Credit Suisse Warburg Pincus Small Company Value Fund may purchase or sell put and call options on individual securities or stock indices as a means of achieving additional return or of hedging the value of its portfolio. The International Funds may purchase and sell put and call options on securities, currencies and financial indices that are traded on U.S. or non-U.S. securities exchanges or in the over-the-counter market. Options traded in the over-the-counter market are considered illiquid investments. The International Funds may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging, return enhancement and risk management purposes in accordance with regulations of the CFTC. These futures contracts and related options will be on financial indices and foreign currencies or groups of foreign currencies. Each of the Credit Suisse Warburg Pincus Strategic Growth Fund's, Credit Suisse Warburg Pincus Technology Fund's and International Fund's successful use of options and financial futures depends on the ability of the Adviser to predict the direction of the market and is subject to various additional risks. The investment techniques and skills required to use options and futures successfully are different from those required to select international securities for investment. The ability of each of these Funds to close out an option or futures position depends on a liquid secondary market. There is no assurance that liquid secondary markets will exist for any particular option or futures contract at any particular time. The inability to close options and futures positions also could have an adverse impact on each Fund's ability to effectively hedge its portfolio. There is also the risk of loss by the Funds of margin deposits or collateral in the event of bankruptcy of a broker with whom the Funds have an open position in an option, a futures contract or related option. LOWER-GRADE SECURITIES. The Credit Suisse Warburg Pincus High Income Fund purchases lower-grade securities. "Lower-grade securities" are regarded as being predominantly speculative as to the issuer's ability to make payments of principal and interest. Investment in these securities involves substantial risk. Lower-grade securities are commonly referred to as "junk bonds." Issuers of lower-grade securities may be highly leveraged and may not have traditional methods of financing. The risks associated with acquiring the securities of these issuers generally are greater than is the case with higher-rated securities. For example, during an economic downturn or a sustained period of rising interest rates, issuers of lower-grade securities may be more likely to experience financial stress, especially if such issuers are highly leveraged. The risk of loss due to default is significantly greater for the holders of lower-grade securities because such securities may be unsecured and may be subordinate to other securities of the issuer. 41 FUND MANAGEMENT As discussed under "Recent Developments," on November 3, 2000, DLJ, the indirect parent of DLJAM was acquired by Credit Suisse. Following the acquisition, CSAM succeeded DLJAM as Adviser of the Credit Suisse Warburg Pincus Funds pursuant to Interim Advisory Agreements. CSAM, located at 466 Lexington Avenue, New York, New York 10017-3147, is a member of Credit Suisse Asset Management, the institutional asset management arm of Credit Suisse Group, one of the world's leading banks. As of December 31, 2000, Credit Suisse Asset Management companies managed approximately $93 billion in the U.S. and $298 billion globally. Except as set forth below, the investment personnel involved in the management of the Funds has not changed. Effective November 1, 2000, the Subadvisory Agreement with AXA Investor Managers GS Ltd. ("AXA") pursuant to which AXA acted as subadviser of the Credit Suisse Warburg Pincus Developing Markets Fund and Credit Suisse Warburg Pincus International Equity II Fund (the "International Funds") was terminated by mutual agreement of the parties. At that time, the Adviser became solely responsible for investment management of the International Funds.

Class B shares will convert to Class A shares approximately eight years from the time of purchase. Class C shares may be purchased for net asset value, but may be subject to a 1% CDSC if redeemed in the first year.

PURCHASES OF COMMON CLASS THROUGH FINANCIAL-SERVICES FIRMS You can buy and sell Common Class shares through a variety of financial-services firms such as banks, brokers and financial advisors. The Credit Suisse Warburg Pincus 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 fund. Please read their program materials of the particular firm for any special provisions or additional service features that may apply to your investment. Certain features of the Common Class shares, such as the minimum initial or subsequent investment amounts, may be modified. 46 B.

Each class has different exchange privileges and only Class B shares have a conversion feature.

The Distributor may pay the dealer a fee of up to 1% as follows: 1% on purchases up to and including $3 million, .50% on the next $47 million, .25% on purchase amounts over $50 million. In addition, Class A shares issued upon conversion of Class B shares of the Funds are not subject to an initial sales charge. From time to time, the Distributor may re-allow the full amount of the sales charge to brokers as a commission for sales of such shares. In addition, investors may be charged a fee by a securities dealer if they effect transactions through a broker or agent. THE INITIAL SALES CHARGE IS WAIVED FOR THE FOLLOWING SHAREHOLDERS OR TRANSACTIONS: (1) investment advisory clients of the Adviser; (2) officers, Trustees and retired Trustees of the Funds, directors or trustees of other investment companies managed by the Adviser, officers, directors and full-time employees of the Adviser and of its wholly-owned subsidiaries or parent entities ("Related Entities"); or the spouse, siblings, children, parents or grandparents of any such person or any such person's spouse (collectively, "relatives"), or any trust or individual retirement account or self-employed retirement plan for the benefit of any such person or relative; or the estate of any such person or relative, if such sales are made for investment purposes (such shares may not be resold except to the Funds); (3) certain employee benefit plans for employees of the Advisers and Related Entities; (4) full-time employees of the Funds' Transfer Agent or an entity that provides distribution to the Funds, an agent or broker of a dealer that has a sales agreement with the Distributor, for their own account or an account of a relative of any such person, or any trust or individual retirement account or self-employed retirement plan for the benefit of any such person or relative; or the estate of any such person or relative, if such sales are made for investment purposes (such shares may not be resold except to the Funds); (5) shares purchased by registered investment advisers on behalf of fee-based accounts or by broker-dealers that have sales agreements with the Funds and for which shares have been purchased on behalf of wrap fee client accounts and for which such registered investment advisers or broker-dealers perform advisory, custodial, record keeping or other services; 52 (6) shareholders who received shares in the Credit Suisse Warburg Pincus Funds as a result of the merger of Neuwirth Fund, Inc., Pine Street Fund, Inc. or deVegh Mutual Fund, Inc., and who have maintained their investment in such shares; (7) shares purchased for 401(k) Plans, 403(b) Plans and 457 Plans; and employee benefit plans sponsored by an employer; non-U.S. nationalized pension plans; and (8) Class B shares which are automatically converted to Class A shares. REDUCED SALES CHARGES ARE AVAILABLE TO PARTICIPANTS IN THE FOLLOWING PROGRAMS: LETTER OF INTENT. By initially investing at least $1,000 and submitting a Letter of Intent to the Funds' Distributor or Transfer Agent, you may purchase shares of a Credit Suisse Warburg Pincus Fund over a 13-month period at the reduced sales charge, which applies, to the aggregate amount of the intended purchases stated in the Letter. The Letter only applies to purchases made up to 90 days before the date of the Letter. RIGHT OF ACCUMULATION. For investors who already have an account with the Funds, reduced sales charges based upon the Funds' sales charge schedules are applicable to subsequent purchases. The sales charge on each additional purchase is determined by adding the current net asset value of the shares the investor currently owns to the amount being invested. The Right of Accumulation is illustrated by the following example: If a previous purchase currently valued in the amount of $50,000 had been made subject to a sales charge and the shares are still held, a current purchase of $50,000 will qualify for a reduced sales charge (i.e., the sales charge on a $100,000 purchase). The reduced sales charge is applicable only to current purchases. It is the investor's responsibility to notify the Transfer Agent at the time of subsequent purchases that the account is eligible for the Right of Accumulation. CONCURRENT PURCHASES. To qualify for a reduced sales charge, you may combine concurrent purchases of shares purchased in any Credit Suisse Warburg Pincus Fund. For example, if the investor concurrently invests $25,000 in one Fund and $25,000 in another, the sales charge would be reduced to reflect a $50,000 purchase. In order to exercise the Concurrent Purchases privilege, the investor must notify the Distributor or Transfer Agent prior to his or her purchase. COMBINED PURCHASE PRIVILEGE. By combining the investor's holdings of shares in any Credit Suisse Warburg Pincus Fund, the investor can reduce the initial sales charges on any additional purchases of Class A shares. The investor may also use these combinations under a Letter of Intent. This allows the investor to make purchases over a 13-month period and qualify the entire purchase for a reduction in initial sales charges on Class A shares. A combined purchase of $1,000,000 or more may trigger the payment of a dealer's commission and the applicability of a Limited CDSC. See "Other Shareholder Information -- Class A Limited CDSC." REINSTATEMENT PRIVILEGE. The Reinstatement Privilege permits shareholders to reinvest the proceeds provided by a redemption of a Fund's Class A shares within 120 days from the date of redemption without an initial sales charge. It is the investor's responsibility to notify the Transfer Agent prior to his or her purchase in order to exercise the Reinstatement Privilege. In addition, a CDSC paid to the Distributor will be eligible for reimbursement at the current net asset value of the applicable Fund if a shareholder reinstates his Fund account holdings within 120 days from the date of redemption. CLASS B SHARES You may choose to purchase Class B shares at the Fund's net asset value although such shares may be subject to a CDSC when you redeem your investment. The CDSC does not apply to investments held for more than four years or shares received pursuant to dividend reinvestment. 53 Where the CDSC is imposed, the amount of the CDSC will depend on the number of years that you have held the shares according to the table on this page. The CDSC will be assessed on an amount equal to the lesser of the then current net asset value or the original purchase price of the shares identified for redemption. - -------------------------------------------------------------------------------- YEAR AFTER PURCHASE CDSC PERCENTAGE - -------------------------------------------------------------------------------- 1st 4% ---------------------------------------------------- 2nd 3% ---------------------------------------------------- 3rd 2% ---------------------------------------------------- 4th 1% ---------------------------------------------------- After 4th year None ---------------------------------------------------- THE CDSC ON CLASS B SHARES WILL BE WAIVED FOR THE FOLLOWING SHAREHOLDERS OR TRANSACTIONS: (1) shares received pursuant to the exchange privilege which are currently exempt from a CDSC; (2) redemptions as a result of shareholder death or disability (as defined in the Internal Revenue Code of 1986, as amended); (3) redemptions made pursuant to a Credit Suisse Warburg Pincus Fund's systematic withdrawal plan pursuant to which up to 1% monthly or 3% quarterly of an account (excluding dividend reinvestments) may be withdrawn, provided that no more than 12% of the total market value of an account may be withdrawn over any 12 month period. Shareholders who elect systematic withdrawals on a semi-annual or annual basis are not eligible for the waiver; and (4) liquidations, distributions or loans from the following types of retirement plan accounts: -Section 401(k) retirement Plans; -Section 403(b) Plans; or -Section 457 Plans; and (5) A redemption related to minimum distributions from retirement plans or accounts at age 70 1/2, which are required without penalty pursuant to the Internal Revenue Code. Redemptions effected by the Funds pursuant to their right to liquidate a shareholder's account with a current net asset value of less than $250 will not be subject to the CDSC. In addition, Class B shares held for eight years after purchase will be automatically converted in Class A shares and accordingly will no longer be subject to the CSDC. CLASS A LIMITED CDSC. A Limited Contingent Deferred Sales Charge ("Limited CDSC") will be imposed by the Funds upon certain redemptions of Class A shares (or shares into which such Class A shares are exchanged) made within 12 months of purchase, if such purchases were made at net asset value and triggered the payment by the Distributor of the dealer's commission described above (i.e., purchases of $1,000,000 or more). The Limited CDSC will be paid to the Distributor and will be equal to the lesser of 1% of: - - the net asset value at the time of purchase of the Class A shares being redeemed; or - - the net asset value of such Class A shares at the time of redemption. For purposes of this formula, the "net asset value at the time of purchase" will be the net asset value at the time of purchase of such Class A shares even if those shares are later exchanged, and in the event of an exchange of such Class A shares, the "net asset value of such shares at the time of redemption" will be the net asset value of the shares into which the Class A shares have been exchanged. The Limited CDSC on Class A shares will be waived on redemptions made pursuant to a Credit Suisse Warburg Pincus Fund's systematic withdrawal plan under the same circumstances as outlined in item (3) above related to the waiver of the CDSC on Class B shares. CLASS C SHARES You may choose to purchase Class C shares at the Fund's net asset value, although such shares will be subject to a 1% CDSC if you redeem your shares within 1 year. If you exchange your shares for Class C shares of another Credit Suisse Warburg Pincus Fund, the 1% CDSC also will apply to those Class C shares. The 1-year period for the CDSC begins with the date of your original purchase, not the date of the exchange for the other Class C shares. The 54 1% CDSC on Class C shares will be waived under the circumstances that would result in a waiver of the CDSC on Class B shares. Class C shares are subject to a distribution fee of 1.00% of average daily net assets. CLASS D SHARES Class D shares are offered only to employees of CSFB and its subsidiaries who are eligible to participate in the Employee Savings and Retirement Plan of Credit Suisse First Boston, certain investment advisory or brokerage clients of CSAM or its affiliates, and certain employee benefit plans for employees of CSAM or its affiliates. Class D shares are not subject to any sales charges or distribution fees. CSFB employees should contact the CSFB 401(k) Hotline at 1-800-588-6200 to learn how to purchase Class D shares. COMMON CLASS SHARES You may choose to purchase Common Class shares at the Fund's net asset value. Common Class shares are not subject to any initial or contingent deferred sales charge, but there is a distribution fee of .25% of average daily net assets. The Distributor, the Adviser or their affiliates may make additional payments out of their own resources to institutions for providing distribution, administrative, accounting and/or other services with respect to Common Class shares. Under certain circumstances, the Funds, on behalf of the Series, may reimburse a portion of these payments. ADVISOR CLASS SHARES Advisor Class shares of the Credit Suisse Warburg Pincus Value Fund are available for purchase through certain institutions and financial services firms and are not available to individual investors directly. These shares will be offered without a front end sales load or a contingent deferred sales charge but will be charged a shareholder service fee payable at an annual rate of up to .25%, and a distribution and/or administrative services fee payable at an annual rate of up to .50% of the average daily net assets of such class. The aggregate distribution and/or shareholder services fee payable by the Advisor Class may not exceed .75% of the average daily net assets relating to that class. The Board of Trustees is currently limiting the amount payable to .50 of 1% of the average daily net assets relating to that class. Payments may be made to an institution directly out of assets of the Fund attributable to the class or by the Distributor on the Fund's behalf. The Distributor, the Adviser or their affiliates may make additional payments out of their own resources to institutions for providing distribution, administrative, accounting and/or other services with respect to Advisor Class shares. Under certain circumstances, the Fund, on behalf of the Series, may reimburse a portion of these payments. 55 ADDITIONAL SHAREHOLDER SERVICES EXCHANGE PRIVILEGE. You may exchange shares of a Fund for shares offered under the same class of another Credit Suisse Warburg Pincus Fund or for shares of the Money Funds. Class A shares may also be exchanged for Common Class shares of another Credit Suisse Warburg Pincus Fund. After about July 1, 2001, Common Class shares of Credit Suisse Warburg Pincus Funds may be exchanged for Common Class shares of funds in the Warburg, Pincus family of funds (and VICE VERSA). Shareholders whose initial investment was directly into a Money Fund may exchange such shares for either Class A, Class B, Class C, or Common Class of another Credit Suisse Warburg Pincus Fund. Shares of each Money Fund purchased pursuant to the Credit Suisse Warburg Pincus Funds' exchange privilege will be eligible for exchange into another Credit Suisse Warburg Pincus Fund provided that the exchange is directed into the same class of shares upon which the initial investment was made. Shareholders whose initial investment was invested directly into a Money Fund will, upon an exchange request, automatically be exchanged into Class A shares of the requested Fund (unless otherwise indicated on the purchase application or by written notice). You should be aware that for federal income tax purposes an exchange is treated as a sale and a purchase of shares which may result in recognition of a gain or loss. THE FOLLOWING PRIVILEGES ARE PROVIDED BY THE TRANSFER AGENT AND DO NOT APPLY TO CLASS D OR ADVISOR CLASS SHARES: AUTOMATIC MONTHLY INVESTMENT PLAN. You may elect on the Application to make additional investments in a Fund automatically by authorizing Credit Suisse Warburg Pincus to withdraw funds from your bank or other cash account and purchase additional shares with those funds. You select the date (either the 10th, 15th or 20th of each month) and amount (subject to a minimum of $25 for Class A, Class B or Class C shares or $50 for Common Class shares). The plan may be terminated at any time without penalty by you or the Fund. AUTOMATIC EXCHANGE PLAN. You may authorize the Credit Suisse Warburg Pincus Funds in advance to exchange a set dollar amount of shares in one Fund for shares of the same class of another Fund or for shares of the Money Funds on a monthly, quarterly, semi-annual or annual basis under an Automatic Exchange Plan. The minimum exchange amount under the Automatic Exchange Plan is $50. These exchanges are subject to the terms of the Exchange Privilege described above. This service is not available for Common Class shares. DIVIDEND DIRECTION OPTION. Any Class A, Class B or Class C shareholder may elect on the Application to have his or her dividends paid to another individual. All shareholders may elect to have his or her dividends directed for reinvestment within the same class of another Fund provided that an existing account in such other Fund is maintained by the shareholder. SYSTEMATIC WITHDRAWAL PLAN. Any Class A, Class B or Class C shareholder who owns or purchases shares of a Fund having a current net asset value of at least $10,000 may establish a Systematic Withdrawal Plan under which the shareholder or a third party will receive payment by check in a stated amount of not less than $50 on a monthly, quarterly, semi-annual or annual basis. A CDSC which may otherwise be imposed on a redemption will be waived in connection with redemptions made pursuant to Credit Suisse Warburg Pincus Funds' Systematic Withdrawal Plan up to 1% monthly or 3% quarterly of an account (excluding dividend reinvestment) not to exceed 12% over any 12 month rolling period. Systematic withdrawals elected on a semi-annual or annual basis are not eligible for the waiver. Common Class shareholders have available the Automatic Withdrawal Plan for making automatic monthly, quarterly, semiannual or annual withdrawals of $250 or more. CHECKWRITING PRIVILEGES. Shareholders of the Money Funds may redeem shares by writing checks of at least $100 against their account balance. Investments in the Money Funds will continue to earn dividends until a shareholder's check is presented to the Money Funds for payment. Checks will be returned by the Transfer Agent if there are insufficient shares to meet the withdrawal amount. You should not attempt to close an account by check because the exact balance at the time the check clears will not be known when the check is written. There is currently no charge to shareholders for checkwriting, but the Money Funds reserve the right to impose a charge in the future. The Money Funds may modify, suspend or terminate checkwriting privileges at any time upon notice to shareholders and will terminate checkwriting privileges without notice for accounts whose assets are exchanged completely out of the Money Funds. In addition, Boston Safe Deposit & Trust., as agent for the Transfer Agent in processing redemptions via the checkwriting privilege, reserves the right to terminate checkwriting privileges at any time without notice to you. Checkwriting privileges are not available for accounts subject to a CDSC. 56 SAVEMYMONEY PROGRAM. Available to Common Class shareholders of certain Funds, SaveMyMoney-SM- is a low minimum, automatic investing program that makes it easy to build a mutual fund portfolio. For an initial investment of $250 along with a minimum $50 monthly investment, you can invest in Common Class shares. The SaveMyMoney Program will automatically transfer the monthly investment amount you designate from your bank account. RETIREMENT PLANS. Credit Suisse Warburg Pincus Funds offer a range of qualified retirement plans including Traditional, Educational and Roth IRAs, SEPs, SIMPLE plans and other pension and profit sharing plans. Semper Trust Company serves as custodian under these prototype retirement plans and charges an annual account maintenance fee of $15 per participant, regardless of the number of Funds selected. To transfer your IRA to Credit Suisse Warburg Pincus, use the IRA TRANSFER/DIRECT ROLLOVER FORM. If you are opening a new IRA, you will also need to complete the UNIVERSAL IRA APPLICATION. Please consult your tax professional concerning your IRA eligibility and tax situation. For more information you should write or telephone the Transfer Agent at 1-800-225-8011. For a more detailed explanation of the retirement plans offered by the Funds, see each Fund's Statement of Additional Information. 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. Additional information concerning shareholder services is available by contacting the Funds at the address or telephone number listed on the last page of this Prospectus. THE FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE FUNDS IF YOU ARE A MARKET-TIMER. THE FUNDS RESERVE THE RIGHT TO IMPOSE SHORT-TERM REDEMPTION FEES TO DISCOURAGE MARKET-TIMING IN THE FUNDS. DISTRIBUTION CHARGES Each Fund has adopted 12b-1 Plans pursuant to the rules of the 1940 Act. These plans allow each Fund to collect distribution and service fees for the sale and servicing of the individual classes of each Fund's shares. Since these fees are paid out of each Fund's assets on an on-going basis, over time these fees will increase the cost of your investment. These fees may cost you more than paying other types of sales charges. Effective as of August 1, 2000, the limitation on annual distribution and service fees for Class A shares of the Credit Suisse Warburg Pincus Blue Chip Fund, Credit Suisse Warburg Pincus Value Fund, Credit Suisse Warburg Pincus Small Company Value Fund, Credit Suisse Warburg Pincus Fixed Income II Fund and Credit Suisse Warburg Pincus Municipal Trust Fund was reduced from 0.30% to 0.25%. Effective as of the date of this Prospectus, the limitation on annual distribution and service fees for the Advisor Class of the Credit Suisse Warburg Pincus Value Fund has been reduced from 0.75% to 0.50%. The Funds do not pay any of the expenses for distributing Class D shares. DISTRIBUTION AND SERVICE FEES: Distribution and service fees are used to pay the Distributor to promote the sale of shares and the servicing of accounts of each Fund. The expenses incurred by the Distributor under the 12b-1 Plans include the preparation, printing and distribution of prospectuses, sales brochures and other promotional materials sent to prospective shareholders. They also include purchasing radio, television, newspaper and other advertising and compensating the Distributor's employees or employees of the Distributor's affiliates for their distribution assistance. Distribution fees also allow the Distributor to compensate broker/dealers or other persons or entities for providing distribution assistance, as well as financial intermediaries for providing administrative and accounting services for their account holders. In addition to commissions and maintenance fees paid to broker/dealers the Distributor may from time to time pay additional compensation to broker/dealers in connection with the sale of shares. Such additional amounts may be utilized to provide additional compensation to registered representatives of such broker/dealers who sell shares of the Fund. On some occasions, such compensation will be conditioned on the sale of a specified minimum dollar amount of the shares of the Funds during a specific period of time. Such incentives may take the form of payment for meals, entertainment, or attendance at educational seminars and associated expenses such as travel and lodging. Such broker/dealers may elect to receive cash incentives of equivalent amounts in lieu of such payments. 57 DIVIDEND AND DISTRIBUTION INFORMATION Dividends are declared daily and paid monthly to shareholders of the Money Funds, the Credit Suisse Warburg Pincus Fixed Income II Fund, the Credit Suisse Warburg Pincus Municipal Trust Fund and the Credit Suisse Warburg Pincus High Income Fund from net investment income. Dividends are paid to shareholders of the Credit Suisse Warburg Pincus Value Fund quarterly, if net investment income has been earned, and to shareholders of the Credit Suisse Warburg Pincus Blue Chip Fund, the Credit Suisse Warburg Pincus Small Company Value Fund, the Credit Suisse Warburg Pincus Strategic Growth Fund, the Credit Suisse Warburg Pincus Technology Fund and the International Funds once a year. Capital gains earned in any of the Funds are normally distributed to shareholders once a year, shortly after the Funds' fiscal year end. For purposes of this calculation, net investment income consists of all accrued interest and dividend income on Fund assets less the Fund expenses applicable to that dividend period. For your convenience, dividends and capital gains are automatically reinvested in your Fund. If you ask us to pay the distributions in cash, the Fund will send you a check instead of purchasing more shares of your Fund. You will receive a confirmation that shows the payment amount and a summary of all transactions. Checks are normally mailed within five business days of the payment date. TAXES As with any investment, you should consider how your investment in the Funds will be taxed. If your account is not a tax-deferred retirement account, you should be aware of these tax consequences. For federal income tax purposes, a Fund's income and short-term capital gain distributions are taxed as ordinary income. Long-term capital gain distributions are taxed as long-term capital gains. Your distributions may also be subject to state and local income taxes. The distributions are taxable when they are paid, whether you receive them in cash or participate in the dividend reinvestment program. Each January, your Fund will mail you a form indicating the federal tax status of your dividend and capital gain distributions. For individuals, long-term capital gains are generally subject to a maximum tax rate of 20%. If you hold shares in a tax-deferred retirement account, your distributions will be taxed when you receive a distribution from your tax-deferred account. Distributions to shareholders of tax-exempt interest income earned by the Credit Suisse Warburg Pincus Municipal Trust Fund and the Credit Suisse Warburg Pincus Municipal Money Fund are not subject to federal income tax if, at the close of each quarter of each Fund's taxable year, at least 50% of the value of each Fund's total assets consists of tax-exempt obligations. Both Funds intend to meet this requirement. Because the Credit Suisse Warburg Pincus Municipal Trust Fund and Credit Suisse Warburg Pincus Municipal Money Fund can invest in taxable municipal bonds and other taxable securities as well as tax-exempt municipal bonds, the portion of their dividends exempt from or subject to regular federal income taxes cannot be predicted. In addition, these distributions may also be subject to state and local taxes. If you are subject to the AMT, you should be aware that a portion of the distributions out of tax-exempt interest earned by the Credit Suisse Warburg Pincus Municipal Trust Fund and the Credit Suisse Warburg Pincus Municipal Money Fund may be taxable. When you redeem your shares, the tax treatment of any gains or losses may be affected by the length of time for which you hold your shares. As a shareholder, you must provide your Fund with a correct taxpayer identification number (generally your Social Security number) and certify that you are not subject to backup withholding. If you fail to do so, the IRS can require your Fund to withhold 31% of your taxable distributions and redemptions. Federal law also requires your Fund to withhold 30% or the applicable tax treaty rate from dividends paid to certain non-resident alien, non-U.S. partnership and non-U.S. corporation shareholder accounts. Please see the Statement of Additional Information for your Fund for more information on the tax consequences of your investment. You should also consult your own tax adviser for further information. THE TAXPAYER RELIEF ACT OF 1997: The Taxpayer Relief Act of 1997 made certain changes to capital gains tax rates. Under this law, certain taxpayers will pay a lower tax rate when it comes to capital gains. The Fund will provide information relating to the portion of any Fund distribution that is eligible for the reduced capital gains tax rate. 58 FINANCIAL HIGHLIGHTS The financial highlights table is intended to help you understand your Fund's financial performance for the past 5 years (or, if shorter, the period of the Fund's operations.) Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the indicated Fund (assuming reinvestment of all dividends and distributions). This information has been audited by Ernst & Young LLP, the Funds' independent auditors, whose unqualified reports, along with the Funds' financial statements, are included in the Statements of Additional Information, which are available upon request. Additional information about the performance of the Funds is contained in each Fund's annual report to shareholders, which may be obtained without charge. Prior to February 28, 1996, the Credit Suisse Warburg Pincus Capital Funds offered only a single class of shares. Accordingly, the data presented below with respect to Class A shares of the Credit Suisse Warburg Pincus Capital Funds for periods prior to such date have been obtained from the financial statements for the Credit Suisse Warburg Pincus Capital Funds' sole class of shares outstanding during such prior fiscal years. Also, Class R shares of the Fund are now designated Common Class. 59 NET ASSET NET NET REALIZED TOTAL DIVIDENDS VALUE INVESTMENT AND UNREALIZED FROM FROM NET BEGINNING INCOME/ GAINS/(LOSSES) INVESTMENT INVESTMENT OF PERIOD (LOSS) ON SECURITIES OPERATIONS INCOME - --------------------------------------------------------------------------------------------------------------------- CREDIT SUISSE WARBURG PINCUS BLUE CHIP FUND CLASS A Year Ended October 31, 2000 ...................... $21.27 $(0.04)* $2.92 $2.88 $ -- Year Ended October 31, 1999 ...................... 16.52 (0.03)* 5.04 5.01 -- Year Ended October 31, 1998 ...................... 14.56 (0.00)*+ 2.88 2.88 (0.02) Year Ended October 31, 1997 ...................... 12.69 0.03 3.07 3.10 (0.05) Year Ended October 31, 1996 ...................... 11.35 0.05 2.11 2.16 (0.04) CLASS B Year Ended October 31, 2000 ...................... 20.75 (0.20)* 2.85 2.65 -- Year Ended October 31, 1999 ...................... 16.25 (0.17)* 4.93 4.76 -- Year Ended October 31, 1998 ...................... 14.41 (0.12)* 2.86 2.74 -- Year Ended October 31, 1997 ...................... 12.63 (0.03) 3.02 2.99 (0.03) Year Ended October 31, 1996+ ..................... 11.88 (0.01) 0.76 0.75 -- CLASS C Year Ended October 31, 2000++++ .................. 20.01 (0.17)* 1.95 1.78 -- CLASS D Year Ended October 31, 2000 ...................... 21.27 0.02* 2.92 2.94 -- Year Ended October 31, 1999++ .................... 20.29 0.01* 0.97 0.98 -- COMMON CLASS Year Ended October 31, 2000++++++ ................ 22.55 (0.02)* 0.02 -- -- - ----------------------------------------------------------------------------------------------------------------------- CREDIT SUISSE WARBURG PINCUS VALUE FUND CLASS A Year Ended October 31, 2000 ...................... $23.49 $0.16* $0.16 $0.32 $(0.12) Year Ended October 31, 1999 ...................... 22.60 0.12* 2.87 2.99 (0.09) Year Ended October 31, 1998 ...................... 20.09 0.20* 3.51 3.71 (0.17) Year Ended October 31, 1997 ...................... 17.18 0.21 4.59 4.80 (0.21) Year Ended October 31, 1996 ...................... 14.57 0.27 2.93 3.20 (0.24) CLASS B Year Ended October 31, 2000 ...................... 23.37 --*+ 0.38 0.38 -- Year Ended October 31, 1999 ...................... 22.55 (0.04)* 2.88 2.84 (0.01) Year Ended October 31, 1998 ...................... 20.06 0.04* 3.50 3.54 (0.02) Year Ended October 31, 1997 ...................... 17.15 0.08 4.58 4.66 (0.07) Year Ended October 31, 1996+ ..................... 16.05 0.14 1.11 1.25 (0.15) CLASS C Year Ended October 31, 2000++++ .................. 20.87 (0.01)* 3.50 3.49 (0.03) CLASS D Year Ended October 31, 2000 ...................... 23.50 0.23* 0.04 0.27 (0.18) Year Ended October 31, 1999+++ ................... 23.73 0.10* (0.26) (0.16) (0.07) COMMON CLASS Year Ended October 31, 2000+++++ ................. 22.44 0.02* 2.13 2.15 (0.04) 60 DISTRIBUTIONS FROM NET ASSET CAPITAL TOTAL VALUE TOTAL GAINS DISTRIBUTIONS END OF PERIOD RETURN** - ------------------------------------------------------------------------------------------------------------------ CREDIT SUISSE WARBURG PINCUS BLUE CHIP FUND CLASS A Year Ended October 31, 2000 ...................... $(1.61) $(1.61) $22.54 14.39% Year Ended October 31, 1999 ......................
