             Summary Information (continued)

Fixed        The "Fixed Income Funds" are the Short-Term, Low Duration, Total
Income       Return, Total Return Mortgage, Foreign Bond, Emerging Markets
Instruments  Bond, High Yield, Short Duration Municipal Income, Municipal Bond,
             California Intermediate Municipal Bond, New York Intermediate
             Municipal Bond, and Real Return Bond Funds. Each Fixed Income Fund
             differs from the others primarily in the length of the Fund's
             duration or the proportion of its investments in certain types of
             fixed income securities. Each Fixed Income Fund invests at least
             65% of its assets in "Fixed Income Instruments," which as used in
             this Prospectus includes:

             . securities issued or guaranteed by the U.S. Government, its
               agencies or instrumentalities ("U.S. Government Securities");
             . corporate debt securities of U.S. and non-U.S. issuers, including
               convertible securities and corporate commercial paper;
             . mortgage-backed and other asset-backed securities;
             . inflation-indexed bonds issued both by governments and
               corporations;
             . structured notes, including hybrid or "indexed" securities,
               event-linked bonds and loan participations;
             . delayed funding loans and revolving credit facilities;
             . bank certificates of deposit, fixed time deposits and bankers'
               acceptances;
             . repurchase agreements and reverse repurchase agreements;
             . debt securities issued by states or local governments and their
               agencies, authorities and other instrumentalities;
             . obligations of non-U.S. governments or their subdivisions,
               agencies and instrumentalities; and
             . obligations of international agencies or supranational
               entities.

Duration     Duration is a measure of the expected life of a fixed income
             security that is used to determine the sensitivity of a security's
             price to changes in interest rates. The longer a security's
             duration, the more sensitive it will be to changes in interest
             rates. Similarly, a Fund with a longer average portfolio duration
             will be more sensitive to changes in interest rates than a Fund
             with a shorter average portfolio duration.

Credit       In this Prospectus, references are made to credit ratings of debt
Ratings      securities which measure an issuer's expected ability to pay
             principal and interest over time. Credit ratings are determined by
             rating organizations, such as Standard & Poor's Rating Service
             ("S&P") or Moody's Investors Service, Inc. ("Moody's"). The
             following terms are generally used to describe the credit quality
             of debt securities depending on the security's credit rating or, if
             unrated, credit quality as determined by PIMCO:

             . high quality
             . investment grade
             . below investment grade ("high yield securities" or "junk bonds")

             For a further description of credit ratings, see "Appendix A--
             Description of Securities Ratings."

Descrip-     following summaries identify each Fund's investment objective,

and Fees     Principal Risks" describing principal risks of investing in the
             Funds begins after the Fund Summaries.

               It is possible to lose money on investments in the Funds.

               An investment in a Fund is not a deposit of a bank and is not
             guaranteed or insured by the Federal Deposit Insurance Corporation
             or any other government agency.

              Short Duration Bond    0-1 year

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 65% of its assets in a
            diversified portfolio of Fixed Income Instruments of varying
            maturities. The average portfolio duration of this Fund normally
            does not exceed one year. For point of reference, the dollar-
            weighted average portfolio maturity of this Fund is normally not
            expected to exceed three years.

              The Fund invests primarily in investment grade debt securities,
            but may invest up to 10% of its assets in high yield securities
            ("junk bonds") rated B or higher by Moody's or S&P, or, if
            unrated, determined by PIMCO to be of comparable quality. The Fund
            may invest up to 5% of its assets in securities denominated in
            foreign currencies, and may invest beyond this limit in U.S.
            dollar-denominated securities of foreign issuers. The Fund will
            normally hedge at least 75% of its exposure to foreign currency to
            reduce the risk of loss due to fluctuations in currency exchange
            rates.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

              . Interest Rate Risk    . Issuer Risk         . Leveraging Risk
              . Credit Risk           . Derivatives Risk    . Management Risk
              . Market Risk           . Mortgage Risk

            Please see "Summary of Principal Risks" following the Fund
            Summaries for a description of these and other risks of investing
            in the Fund.

- --------------------------------------------------------------------------------
Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average
            Annual Total Returns table show performance of the Fund's
            Institutional Class Shares, which are offered in a different
            prospectus. This is because the Fund has not offered Class D
            shares for a full calendar year. Although Class D and
            Institutional Class shares would have similar annual returns
            (because all the Fund's shares represent interests in the same
            portfolio of securities), Class D performance would be lower than
            Institutional Class performance because of the higher expenses
            paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future
            results.

         (1) The Fund's administration agreement includes a plan for Class
             D shares that has been adopted in conformity with the
             requirements set forth in Rule 12b-1 under the Investment Company
             Act of 1940. Up to 0.25% per year of the total fees paid under
             the administration agreement may be distribution and/or service
             (12b-1) fees. The Fund will pay a total of 0.50% per year under
             the administration agreement regardless of whether a portion or
             none of the 0.25% authorized under the plan is paid under the
             plan. Please see "Management of the Funds--Investment Adviser and
             Administrator--Administrative Fees" for details. The Fund intends
             to treat any fees paid under the plan as "service fees" for
             purposes of applicable rules of the National Association of
             Securities Dealers, Inc. (the "NASD"). To the extent that such
             fees are deemed not to be "service fees," Class D shareholders
             may, depending on the length of time the shares are held, pay
             more than the economic equivalent of the maximum front-end sales
             charges permitted by relevant rules of the NASD.
         (2) Other Expenses reflects the portion of the Administrative Fee
             paid by the class that is not reflected under Distribution
             and/or Service (12b-1) Fees.

         Examples. The Examples are intended to help you compare the cost of
         investing in Class D shares of the Fund with the costs of investing in
         other mutual funds. The Examples assume that you invest $10,000 in the
         noted class of shares for the time periods indicated, and then redeem
         all your shares at the end of those periods. The Examples also assume
         that your investment has a 5% return each year, the reinvestment of all
         dividends and distributions, and that the Fund's operating expenses
         remain the same. Although your actual costs may be higher or lower, the
         Examples show what your costs would be based on these assumptions.

              Fund Category
              Short Duration Bond

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 65% of its assets in a
            diversified portfolio of Fixed Income Instruments of varying
            maturities. The average portfolio duration of this Fund normally
            varies within a one- to three-year time frame based on PIMCO's
            forecast for interest rates.

              The Fund invests primarily in investment grade debt securities,
            but may invest up to 10% of its assets in high yield securities
            ("junk bonds") rated B or higher by Moody's or S&P, or, if unrated,
            determined by PIMCO to be of comparable quality. The Fund may invest
            up to 20% of its assets in securities denominated in foreign
            currencies, and may invest beyond this limit in U.S. dollar-
            denominated securities of foreign issuers. The Fund will normally
            hedge at least 75% of its exposure to foreign currency to reduce the
            risk of loss due to fluctuations in currency exchange rates.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities. The "total return" sought by the Fund
            consists of income earned on the Fund's investments, plus capital
            appreciation, if any, which generally arises from decreases in
            interest rates or improving credit fundamentals for a particular
            sector or security.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

              . Credit Risk         . Liquidity Risk       . Leveraging Risk

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

            (1) The Fund's administration agreement includes a plan for Class
                D shares that has been adopted in conformity with the
                requirements set forth in Rule 12b-1 under the Investment
                Company Act of 1940. Up to 0.25% per year of the total fees
                paid under the administration agreement may be distribution
                and/or service (12b-1) fees. The Fund will pay a total of
                0.50% per year under the administration agreement regardless
                of whether a portion or none of the 0.25% authorized under the
                plan is paid under the plan. Please see "Management of the
                Funds--Investment Adviser and Administrator--Administrative
                Fees" for details. The Fund intends to treat any fees paid
                under the plan as "service fees" for purposes of applicable
                rules of the National Association of Securities Dealers, Inc.
                (the "NASD"). To the extent that such fees are deemed not to
                be "service fees," Class D shareholders may, depending on the
                length of time the shares are held, pay more than the economic
                equivalent of the maximum front-end sales charges permitted by
                relevant rules of the NASD.

            (2) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that is not reflected under Distribution
                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

              Bond

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 65% of its assets in a
            diversified portfolio of Fixed Income Instruments of varying
            maturities. The average portfolio duration of this Fund normally
            varies within a three- to six-year time frame based on PIMCO's
            forecast for interest rates.

              The Fund invests primarily in investment grade debt securities,
            but may invest up to 10% of its assets in high yield securities
            ("junk bonds") rated B or higher by Moody's or S&P or, if unrated,
            determined by PIMCO to be of comparable quality. The Fund may invest
            up to 20% of its assets in securities denominated in foreign
            currencies, and may invest beyond this limit in U.S. dollar-
            denominated securities of foreign issuers. The Fund will normally
            hedge at least 75% of its exposure to foreign currency to reduce the
            risk of loss due to fluctuations in currency exchange rates.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities. The "total return" sought by the Fund
            consists of income earned on the Fund's investments, plus capital
            appreciation, if any, which generally arises from decreases in
            interest rates or improving credit fundamentals for a particular
            sector or security.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

              . Interest Rate Risk  . Derivatives Risk      . Currency Risk
              . Credit Risk         . Liquidity Risk        . Leveraging Risk

            Summaries for a description of these and other risks of investing
            in the Fund.

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

            (1) The Fund's administration agreement includes a plan for Class
                D shares that has been adopted in conformity with the
                requirements set forth in Rule 12b-1 under the Investment
                Company Act of 1940. Up to 0.25% per year of the total fees
                paid under the administration agreement may be distribution
                and/or service (12b-1) fees. The Fund will pay a total of
                0.50% per year under the administration agreement regardless
                of whether a portion or none of the 0.25% authorized under the
                plan is paid under the plan. Please see "Management of the
                Funds--Investment Adviser and Administrator--Administrative
                Fees" for details. The Fund intends to treat any fees paid
                under the plan as "service fees" for purposes of applicable
                rules of the National Association of Securities Dealers, Inc.
                (the "NASD"). To the extent that such fees are deemed not to
                be "service fees," Class D shareholders may, depending on the
                length of time the shares are held, pay more than the economic
                equivalent of the maximum front-end sales charges permitted by
                relevant rules of the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee

                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

              Bond

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 80% of its assets in a
            diversified portfolio of mortgage-related Fixed Income Instruments
            of varying maturities. The average portfolio duration of this Fund
            normally varies within a two- to six-year time frame based on
            PIMCO's forecast for interest rates.

              The Fund invests primarily in securities that are in the highest
            rating category, but may invest up to 10% of its assets in
            securities rated below Aaa by Moody's or AAA by S&P, subject to a
            minimum rating of Baa by Moody's or BBB by S&P, or, if unrated,
            determined by PIMCO to be of comparable quality. The Fund may not
            invest in securities denominated in foreign currencies, but may
            invest without limit in U.S. dollar-denominated securities of
            foreign issuers.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities. The "total return" sought by the Fund
            consists of income earned on the Fund's investments, plus capital
            appreciation, if any, which generally arises from decreases in
            interest rates or improving credit fundamentals for a particular
            sector or security.

            Please see "Summary of Principal Risks" following the Fund
            Summaries for a description of these and other risks of investing
            in the Fund.

- --------------------------------------------------------------------------------
Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

                D shares that has been adopted in conformity with the
                requirements set forth in Rule 12b-1 under the Investment
                Company Act of 1940. Up to 0.25% per year of the total fees
                paid under the administration agreement may be distribution
                and/or service (12b-1) fees. The Fund will pay a total of
                0.65% per year under the administration agreement regardless
                of whether a portion or none of the 0.25% authorized under the
                plan is paid under the plan. Please see "Management of the
                Funds--Investment Adviser and Administrator--Administrative
                Fees" for details. The Fund intends to treat any fees paid
                under the plan as "service fees" for purposes of applicable
                rules of the National Association of Securities Dealers, Inc.
                (the "NASD"). To the extent that such fees are deemed not to
                be "service fees," Class D shareholders may, depending on the
                length of time the shares are held, pay more than the economic
                equivalent of the maximum front-end sales charges permitted by
                relevant rules of the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee

                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

              International Bond     3-7 years

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 85% of its assets in Fixed
            Income Instruments of issuers located outside the United States,
            representing at least three foreign countries, which may be
            represented by futures contracts (including related options) with
            respect to such securities, and options on such securities. Such
            securities normally are denominated in major foreign currencies or
            baskets of foreign currencies (such as the euro). The Fund will
            normally hedge at least 75% of its exposure to foreign currency to
            reduce the risk of loss due to fluctuations in currency exchange
            rates.

              PIMCO selects the Fund's foreign country and currency compositions
            based on an evaluation of relative interest rates, exchange rates,
            monetary and fiscal policies, trade and current account balances,
            and any other factors PIMCO believes to be relevant. The average
            portfolio duration of this Fund normally varies within a three- to
            seven-year time frame. The Fund invests primarily in investment
            grade debt securities, but may invest up to 10% of its assets in
            high yield securities ("junk bonds") rated B or higher by Moody's or
            S&P, or, if unrated, determined by PIMCO to be of comparable
            quality. The Fund is non-diversified, which means that it may
            concentrate its assets in a smaller number of issuers than a
            diversified Fund.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities. The "total return" sought by the Fund
            consists of income earned on the Fund's investments, plus capital
            appreciation, if any, which generally arises from decreases in
            interest rates or improving credit fundamentals for a particular
            sector or security.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

             . Interest Rate Risk  . Foreign Investment Risk  . Mortgage Risk
             . Credit Risk         . Currency Risk            . Derivatives Risk
             . Market Risk         . Concentration Risk       . Leveraging Risk
             . Issuer Risk         . Liquidity Risk           . Management Risk

            Please see "Summary of Principal Risks" following the Fund Summaries
            for a description of these and other risks of investing in the Fund.

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

              Fund Category           0-8 years
              International Bond

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 80% of its assets in Fixed
            Income Instruments of issuers that economically are tied to
            countries with emerging securities markets. Such securities may be
            denominated in foreign currencies and the U.S. dollar. The Fund may
            invest up to 10% of its assets in shares of investment companies
            that invest primarily in emerging market debt securities. The
            average portfolio duration of the Fund varies based on PIMCO's
            forecast for interest rates and, under normal market conditions, is
            not expected to exceed eight years.

              PIMCO has broad discretion to identify and invest in countries
            that it considers to qualify as emerging securities markets.
            However, PIMCO generally considers an emerging securities market to
            be one located in any country that is defined as an emerging or
            developing economy by the World Bank or its related organizations,
            or the United Nations or its authorities. The Fund emphasizes
            countries with relatively low gross national product per capita and
            with the potential for rapid economic growth. PIMCO will select the
            Fund's country and currency composition based on its evaluation of
            relative interest rates, inflation rates, exchange rates, monetary
            and fiscal policies, trade and current account balances, and any
            other specific factors PIMCO believes to be relevant. The Fund
            likely will concentrate its investments in Asia, Africa, the Middle
            East, Latin America and the developing countries of Europe. The Fund
            may invest in securities whose return is based on the return of an
            emerging securities market, rather than investing directly in
            securities of issuers from emerging markets. The Fund may invest
            substantially all of its assets in high yield securities ("junk
            bonds") rated B or higher by Moody's or S&P, or, if unrated,
            determined by PIMCO to be of comparable quality. The Fund is non-
            diversified, which means that it may concentrate its assets in a
            smaller number of issuers than a diversified Fund.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities. The "total return" sought by the Fund
            consists of income earned on the Fund's investments, plus capital
            appreciation, if any, which generally arises from decreases in
            interest rates or improving credit fundamentals for a particular
            sector or security.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

             . Interest Rate Risk  . Emerging Markets Risk  . Liquidity Risk
             . Credit Risk         . Foreign Investment     . Derivatives Risk
             . High Yield Risk       Risk                   . Leveraging Risk

             . Issuer Risk         . Concentration Risk

            Please see "Summary of Principal Risks" following the Fund
            Summaries for a description of these and other risks of investing
            in the Fund.

- --------------------------------------------------------------------------------
Performance The top of the next page shows summary performance information
Information for the Fund in a bar chart and an Average Annual Total Returns
            table. The information provides some indication of the risks of
            investing in the Fund by showing changes in its performance from
            year to year and by showing how the Fund's average annual returns
            compare with the returns of a broad-based securities market index
            and an index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. The performance of the
            Class D Shares is based on the performance of the Fund's
            Institutional Class shares, adjusted to reflect the actual
            12b-1/service fees and other expenses paid by Class D shares. Past
            performance is no guarantee of future results.

            (1) The Fund's administration agreement includes a plan for Class
                D shares that has been adopted in conformity with the
                requirements set forth in Rule 12b-1 under the Investment
                Company Act of 1940. Up to 0.25% per year of the total fees
                paid under the administration agreement may be distribution
                and/or service (12b-1) fees. The Fund will pay a total of
                0.80% per year under the administration agreement regardless
                of whether a portion or none of the 0.25% authorized under the
                plan is paid under the plan. Please see "Management of the
                Funds--Investment Adviser and Administrator--Administrative
                Fees" for details. The Fund intends to treat any fees paid
                under the plan as "service fees" for purposes of applicable
                rules of the National Association of Securities Dealers, Inc.
                (the "NASD"). To the extent that such fees are deemed not to
                be "service fees," Class D shareholders may, depending on the
                length of time the shares are held, pay more than the economic
                equivalent of the maximum front-end sales charges permitted by
                relevant rules of the NASD.
            (2) Other expenses reflects the portion of Administrative Fee paid
                by the class that is not reflected under Distribution and/or
                Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, your investment has a 5% return each year, the
            reinvestment of all dividends and distributions, and that the
            Fund's operating expenses remain the same. Although your actual
            costs may be higher or lower, the Examples show what your costs
            would be based on these assumptions.

              High Yield Bond

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 65% of its assets in a
            diversified portfolio of high yield securities ("junk bonds")
            rated below investment grade but rated at least B by Moody's or
            S&P, or, if unrated, determined by PIMCO to be of comparable
            quality. The remainder of the Fund's assets may be invested in
            investment grade Fixed Income Instruments. The average portfolio
            duration of this Fund normally varies within a two- to six-year
            time frame based on PIMCO's forecast for interest rates. The Fund
            may invest without limit in U.S. dollar-denominated securities of
            foreign issuers. The Fund may invest up to 15% of its assets in
            euro-denominated securities. The Fund normally will hedge at least
            75% of its exposure to the euro to reduce the risk of loss due to
            fluctuations in currency exchange rates.

              The Fund may invest up to 15% of its assets in derivative
            instruments, such as options, futures contracts or swap agreements.
            The Fund may invest all of its assets in mortgage or asset backed
            securities. The Fund may lend its portfolio securities to brokers,
            dealers and other financial institutions to earn income. Rather than
            investing directly in the securities in which it primarily invests,
            the Fund may use other investment techniques to gain exposure to
            market movements related to such securities, such as entering into a
            series of contracts to buy or sell such securities. The "total
            return" sought by the Fund consists of income earned on the Fund's
            investments, plus capital appreciation, if any, which generally
            arises from decreases in interest rates or improving credit
            fundamentals for a particular sector or security.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

                requirements set forth in Rule 12b-1 under the Investment
                Company Act of 1940. Up to 0.25% per year of the total fees
                paid under the administration agreement may be distribution
                and/or service (12b-1) fees. The Fund will pay a total of
                0.65% per year under the administration agreement regardless
                of whether a portion or none of the 0.25% authorized under the
                plan is paid under the plan. Please see "Management of the
                Funds--Investment Adviser and Administrator--Administrative
                Fees" for details. The Fund intends to treat any fees paid
                under the plan as "service fees" for purposes of applicable
                rules of the National Association of Securities Dealers, Inc.
                (the "NASD"). To the extent that such fees are deemed not to
                be "service fees," Class D shareholders may, depending on the
                length of time the shares are held, pay more than the economic
                equivalent of the maximum front-end sales charges permitted by
                relevant rules of the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee

                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

                                     0-2 years

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 80% of its net assets in debt
            securities whose interest is, in the opinion of bond counsel for
            the issuer at the time of issuance, exempt from federal income tax
            ("Municipal Bonds"). Municipal Bonds generally are issued by or on
            behalf of states and local governments and their agencies,
            authorities and other instrumentalities.

              The Fund may invest without limit in "private activity" bonds
            whose interest is a tax-preference item for purposes of the federal
            alternative minimum tax ("AMT"). For shareholders subject to the
            AMT, a substantial portion of the Fund's distributions may not be
            exempt from federal income tax. The Fund may invest up to 20% of its
            net assets in other types of Fixed Income Instruments. The Fund may
            only invest in investment grade debt securities. The Fund may invest
            more than 25% of its assets in bonds of issuers in California and
            New York. The average portfolio duration of this Fund varies based
            on PIMCO's forecast for interest rates and under normal market
            conditions is not expected to exceed two years. The Fund will seek
            income that is high relative to prevailing rates from Municipal
            Bonds.

              The Fund may invest in derivative instruments, such as options,
            futures contracts or swap agreements, or in mortgage- or asset-
            backed securities. The Fund may lend its portfolio securities to
            brokers, dealers and other financial institutions to earn income.
            Rather than investing directly in securities in which it primarily
            invests, the Fund may use other investment techniques to gain
            exposure to market movements related to such securities, such as
            entering into a series of contracts to buy and sell such securities.

            behalf of states and local governments and their agencies,
            authorities and other instrumentalities.

              The Fund may invest up to 20% of its net assets in U.S. Government
            Securities, money market instruments and/or "private activity"
            bonds. For shareholders subject to the federal alternative minimum
            tax ("AMT"), distributions derived from "private activity" bonds
            must be included in their AMT calculations, and as such may be
            subject to federal income tax. The Fund invests primarily in
            investment grade debt securities, but may invest up to 10% of its
            net assets in Municipal Bonds or "private activity" bonds which are
            high yield securities ("junk bonds") but rated at least Ba by
            Moody's or BB by S&P, or, if unrated, determined by PIMCO to be of
            comparable quality. The Fund may invest more than 25% of its assets
            in bonds of issuers in California and New York. The average
            portfolio duration of this Fund normally varies within a three- to
            ten-year time frame based on PIMCO's forecast for interest rates.

              The Fund may invest in derivative instruments, such as options and
            futures, on U.S. Government Securities and Municipal Bonds, and
            invest in mortgage- or asset-backed securities. The Fund may lend
            its portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

            (1)  The Fund's administration agreement includes a plan for Class
                 D shares that has been adopted in conformity with the
                 requirements set forth in Rule 12b-1 under the Investment
                 Company Act of 1940. Up to 0.25% per year of the total fees
                 paid under the administration agreement may be distribution
                 and/or service (12b-1) fees. The Fund will pay a total of
                 0.60% per year under the administration agreement regardless
                 of whether a portion or none of the 0.25% authorized under
                 the plan is paid under the plan. Please see "Management of
                 the Funds--Investment Adviser and Administrator--
                 Administrative Fees" for details. The Fund intends to treat
                 any fees paid under the plan as "service fees" for purposes
                 of applicable rules of the National Association of Securities
                 Dealers, Inc. (the "NASD"). To the extent that such fees are
                 deemed not to be "service fees," Class D shareholders may,
                 depending on the length of time the shares are held, pay more
                 than the economic equivalent of the maximum front-end sales
                 charges permitted by relevant rules of the NASD.
            (2)  Other Expenses reflects the portion of the Administrative Fee
                 paid by the class that is not reflected under Distribution
                 and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

                                      3-7 years

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 80% of its net assets in
            Municipal Bonds whose interest is, in the opinion of bond counsel
            for the issuer at the time of issuance, exempt from federal income
            tax. The Fund invests under normal circumstances at least 65% of
            its assets in debt securities whose interest is, in the opinion of
            bond counsel for the issuer at the time of issuance, exempt from
            regular federal income tax and California income tax ("California
            Municipal Bonds"). California Municipal Bonds generally are issued
            by or on behalf of the State of California and its political
            subdivisions, financing authorities and their agencies.

              The Fund may invest without limit in "private activity" bonds
            whose interest is a tax-preference item for purposes of the
            federal alternative minimum tax ("AMT"). For shareholders subject
            to the AMT, a substantial portion of the Fund's distributions may
            not be exempt from federal income tax. The Fund may invest up to
            20% of its net assets in other types of Fixed Income Instruments.
            The average portfolio duration of this Fund normally varies within
            a three- to seven-year time frame based on the PIMCO's forecast
            for interest rates. The Fund will seek income that is high
            relative to prevailing rates from Municipal Bonds. Capital
            appreciation, if any, generally arises from decreases in interest
            rates or improving credit fundamentals for a particular state,
            municipality or issuer.

              The Fund invests primarily in investment grade debt securities,
            but may invest up to 10% of its assets in high yield securities
            ("junk bonds") rated B or higher by Moody's or S&P, or, if
            unrated, determined by PIMCO to be of comparable quality.

              The Fund may invest in derivative instruments, such as options,
            futures contracts or swap agreements, or in mortgage- or asset-
            backed securities. The Fund may lend its portfolio securities to
            brokers, dealers and other financial institutions to earn income.
            Rather than investing directly in securities in which it primarily
            invests, the Fund may use other investment techniques to gain
            exposure to market movements related to such securities, such as
            entering into a series of contracts to buy or sell such securities.

         (1) The Fund's administration agreement includes a plan for Class D

             set forth in Rule 12b-1 under the Investment Company Act of 1940.
             Up to 0.25% per year of the total fees paid under the
             administration agreement may be distribution and/or service (12b-1)
             fees. The Fund will pay a total of 0.60% per year under the
             administration agreement regardless of whether a portion or none of
             the 0.25% authorized under the plan is paid under the plan. Please
             see "Management of the Funds--Investment Adviser and
             Administrator--Administrative Fees" for details. The Fund intends
             to treat any fees paid under the plan as "service fees" for
             purposes of applicable rules of the National Association of
             Securities Dealers, Inc. (the "NASD"). To the extent that such fees
             are deemed not to be "service fees," Class D shareholders may,

             the economic equivalent of the maximum front-end sales charges

         (1) The Fund's administration agreement includes a plan for Class D
             shares that has been adopted in conformity with the requirements
             set forth in Rule 12b-1 under the Investment Company Act of 1940.
             Up to 0.25% per year of the total fees paid under the
             administration agreement may be distribution and/or service (12b-1)
             fees. The Fund will pay a total of 0.60% per year under the
             administration agreement regardless of whether a portion or none of
             the 0.25% authorized under the plan is paid under the plan. Please
             see "Management of the Funds--Investment Adviser and
             Administrator--Administrative Fees" for details. The Fund intends
             to treat any fees paid under the plan as "service fees" for
             purposes of applicable rules of the National Association of
             Securities Dealers, Inc. (the "NASD"). To the extent that such fees
             are deemed not to be "service fees," Class D shareholders may,
             depending on the length of time the shares are held, pay more than
             the economic equivalent of the maximum front-end sales charges
             permitted by relevant rules of the NASD.
         (2) Other expenses reflects the portion of Administrative Fee paid by
             the class that is not reflected under Distribution and/or Service
             (12b-1) Fees.

         Examples. The Examples are intended to help you compare the cost of
         investing in Class D shares of the Fund with the costs of investing in
         other mutual funds. The Examples assume that you invest $10,000 in the
         noted class of shares for the time periods indicated, your investment
         has a 5% return each year, the reinvestment of all dividends and
         distributions, and that the Fund's operating expenses remain the same.
         Although your actual costs may be higher or lower, the Examples show
         what your costs would be based on these assumptions.

              Fund Category           below
              Inflation-Indexed Bond

            The Fund seeks its investment objective by investing under normal
            circumstances at least 65% of its assets in inflation-indexed bonds
            of varying maturities issued by the U.S. and non-U.S. governments,
            their agencies or instrumentalities, and corporations. Inflation-
            indexed bonds are fixed income securities that are structured to
            provide protection against inflation. The value of the bond's
            principal or the interest income paid on the bond is adjusted to
            track changes in an official inflation measure. The U.S. Treasury
            uses the Consumer Price Index for Urban Consumers as the inflation
            measure. Inflation-indexed bonds issued by a foreign government are
            generally adjusted to reflect a comparable inflation index,
            calculated by that government. "Real return" is a measure of the
            change in purchasing power of money invested in a particular
            instrument after adjusting for inflation.

              Because of the unique features of inflation-indexed bonds, PIMCO
            uses a modified form of duration for the Fund ("real duration")
            which measures price changes as a result of changes in "real"
            interest rates. A "real" interest rate is the market interest rate
            minus expected inflation. There is no limit on the real duration of
            the Fund, but it is expected that the average real duration of this
            Fund will normally vary approximately within the range of the
            average real duration of all inflation-indexed bonds issued by the
            U.S. Treasury in the aggregate, which as of January 21, 2000 was 9.2
            years. For point of reference, it is expected that the average
            portfolio duration (as opposed to real duration) of this Fund will
            generally vary with a one- to five-year time frame, although this
            range is subject to change. The Fund may invest in fixed income
            securities of any maturity.

              The Fund invests primarily in investment grade securities, but may
            invest up to 10% of its assets in high yield securities ("junk
            bonds") rated B or higher by Moody's or S&P, or, if unrated,
            determined by PIMCO to be of comparable quality. The Fund may invest
            up to 35% of its assets in non-inflation indexed Fixed Income
            Instruments. The Fund also may invest up to 35% of its assets in
            securities denominated in foreign currencies, and may invest beyond
            this limit in U.S. dollar denominated securities of foreign issuers.
            The Fund will normally hedge at least 75% of its exposure to foreign
            currency to reduce the risk of loss due to fluctuations in currency
            exchange rates. The Fund is non-diversified, which means that it may
            concentrate its assets in a smaller number of issuers than a
            diversified Fund.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements, or in
            mortgage- or asset-backed securities. The Fund may lend its
            portfolio securities to brokers, dealers and other financial
            institutions to earn income. Rather than investing directly in the
            securities in which it primarily invests, the Fund may use other
            investment techniques to gain exposure to market movements related
            to such securities, such as entering into a series of contracts to
            buy or sell such securities.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

             . Interest Rate Risk  . Derivatives Risk         . Currency Risk
             . Credit Risk         . Liquidity Risk           . Leveraging Risk

            Summaries for a description of these and other risks of investing
            in the Fund.

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

                 Company Act of 1940. Up to 0.25% per year of the total fees
                 paid under the administration agreement may be distribution
                 and/or service (12b-1) fees. The Fund will pay a total of
                 0.65% per year under the administration agreement regardless
                 of whether a portion or none of the 0.25% authorized under
                 the plan is paid under the plan. Please see "Management of

                 any fees paid under the plan as "service fees" for purposes
                 of applicable rules of the National Association of Securities
                 Dealers, Inc. (the "NASD"). To the extent that such fees are

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

            The Fund seeks to achieve its investment objective by investing
            under normal circumstances at least 65% of its assets in a
            diversified portfolio of convertible securities. Convertible
            securities include but are not limited to: corporate bonds,
            debentures, notes or preferred stocks and their hybrids that can
            be converted into (exchanged for) common stock or other
            securities, such as warrants or options, which provide an
            opportunity for equity participation.

              The Fund invests primarily in investment grade debt securities,
            but may invest up to 35% of its assets in high yield securities
            ("junk bonds") rated Caa or higher by Moody's or CCC or higher by
            S&P or, if unrated, determined by PIMCO to be of comparable quality.

            securities rated Caa or CCC or, if unrated, determined by PIMCO to

            assets in securities denominated in foreign currencies, and may
            invest beyond this limit in U.S. dollar-denominated securities of
            foreign issuers. In addition, the Fund may invest up to 35% of its
            assets in common stocks or in other Fixed Income Instruments.

              Rather than investing directly in the securities in which it
            primarily invests, the Fund may use other investment techniques to
            gain exposure to market movements related to such securities, such
            as entering into a series of contracts to buy or sell such
            securities. The "total return" sought by the Fund consists of income
            earned on the Fund's investments, plus capital appreciation arising
            from increases in the market value of the Fund's holdings.

         (1) The Fund's administration agreement includes a plan for Class D
             shares that has been adopted in conformity with the requirements
             set forth in Rule 12b-1 under the Investment Company Act of 1940.
             Up to 0.25% per year of the total fees paid under the
             administration agreement may be distribution and/or service (12b-1)
             fees. The Fund will pay a total of 0.65% per year under the
             administration agreement regardless of whether a portion or none of
             the 0.25% authorized under the plan is paid under the plan. Please
             see "Management of the Funds--Investment Adviser and
             Administrator--Administrative Fees" for details. The Fund intends
             to treat any fees paid under the plan as "service fees" for
             purposes of applicable rules of the National Association of
             Securities Dealers, Inc. (the "NASD"). To the extent that such fees
             are deemed not to be "service fees," Class D shareholders may,
             depending on the length of time the shares are held, pay more than
             the economic equivalent of the maximum front-end sales charges
             permitted by relevant rules of the NASD.

         (2) Other expenses reflects the portion of Administrative Fee paid by
             the class that is not reflected under Distribution and/or Service
             (12b-1) Fees.

         Examples. The Examples are intended to help you compare the cost of
         investing in Class D shares of the Fund with the costs of investing in
         other mutual funds. The Examples assume that you invest $10,000 in the
         noted class of shares for the time periods indicated, your investment
         has a 5% return each year, the reinvestment of all dividends and
         distributions, and that the Fund's operating expenses remain the same.
         Although your actual costs may be higher or lower, the Examples show
         what your costs would be based on these assumptions.

            The Fund seeks to achieve its investment objective by normally
            investing in a combination of fixed income securities and equity
            securities or derivatives on equity securities. The percentage of
            the Fund's assets invested in equities and equity derivatives or in
            fixed income securities will be determined based on methodology,
            developed by PIMCO, that forecasts stages in the business cycle and
            considers the risk and reward potential of equity and fixed income
            securities within specific phases of the business cycle. The Fund's
            equity exposure will vary between 45% and 75% of assets, and its
            fixed income exposure will range from a minimum of 25% to a maximum
            of 55%.

              The Fund's equity exposure normally consists of S&P 500
            derivatives, backed by a portfolio of short-term Fixed Income
            Instruments. PIMCO uses S&P 500 derivatives in addition to or in
            place of S&P 500 stocks to attempt to equal or exceed the
            performance of the S&P 500. The value of S&P 500 derivatives closely
            track changes in the value of the index. However, S&P 500
            derivatives may be purchased with a fraction of the assets that
            would be needed to purchase the equity securities directly, so that
            the remainder of the assets may be invested in Fixed Income
            Instruments. PIMCO will actively manage the fixed income assets
            serving as cover for derivatives, as well as any other fixed income
            assets held by the Fund, with a view toward enhancing the Fund's
            total return investment performance. Though the Fund does not
            normally invest directly in S&P 500 securities, when S&P 500
            derivatives appear to be overvalued relative to the S&P 500, the
            Fund may invest the equity portion of its assets in a "basket" of
            S&P 500 stocks.

              The Fund's fixed income exposure will normally consist of a
            diversified portfolio of Fixed Income Instruments of varying
            maturities. The average portfolio duration of the fixed income
            portion of this Fund's assets will normally vary within a three-to
            six-year time frame based on PIMCO's forecast for interest rates.
            The Fixed Income Instruments in which the Fund invests are primarily
            investment grade, but the Fund may invest up to 10% of its assets in
            high yield securities ("junk bonds") rated B or higher by Moody's or
            S&P, or, if unrated, determined by PIMCO to be of comparable
            quality. The Fund may invest up to 20% of its assets in securities
            denominated in foreign currencies, and may invest beyond this limit
            in U.S. dollar denominated securities of foreign issuers. The Fund
            will normally hedge at least 75% of its exposure to foreign currency
            to reduce the risk of loss due to fluctuations in currency exchange
            rates.

              The Fund may invest all of its assets in derivative instruments,
            such as options, futures contracts or swap agreements. The Fund may
            lend its portfolio securities to brokers, dealers and other
            financial institutions to earn income. Rather than investing
            directly in the securities in which it primarily invests, the Fund
            may use other investment techniques to gain exposure to market
            movements related to such securities, such as entering into a series
            of contracts to buy or sell such securities. The "total return"
            sought by the Fund consists of net income earned on the Fund's
            investments, plus capital appreciation arising from increases in the
            market value of the Fund's holdings.

Principal   Among the principal risks of investing in the Fund, which could
Risks       adversely affect its net asset value, yield and total return, are:

             . Market Risk         . Derivatives Risk         . Mortgage Risk
             . Issuer Risk         . Liquidity Risk           . Leveraging Risk
             . Interest Rate Risk  . Foreign Investment Risk  . Management Risk
             . Credit Risk         . Currency Risk

            Please see "Summary of Principal Risks" following the Fund
            Summaries for a description of these and other risks of investing
            in the Fund.

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of broad-based securities market indices and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future results.

                                     0-1 year

            The Fund seeks to exceed the total return of the S&P 500 by
            investing under normal circumstances substantially all of its
            assets in S&P 500 derivatives, backed by a portfolio of Fixed
            Income Instruments. The Fund may invest in common stocks, options,
            futures, options on futures and swaps. The Fund uses S&P 500
            derivatives in addition to or in place of S&P 500 stocks to
            attempt to equal or exceed the performance of the S&P 500. The
            value of S&P 500 derivatives closely track changes in the value of
            the index. However, S&P 500 derivatives may be purchased with a
            fraction of the assets that would be needed to purchase the equity
            securities directly, so that the remainder of the assets may be
            invested in Fixed Income Instruments. PIMCO actively manages the
            fixed income assets held by the Fund with a view toward enhancing
            the Fund's total return, subject to an overall portfolio duration
            which is normally not expected to exceed one year.

              The S&P 500 is composed of 500 selected common stocks that
            represent approximately two-thirds of the total market value of all
            U.S. common stocks. The Fund is neither sponsored by nor affiliated
            with S&P. The Fund seeks to remain invested in S&P 500 derivatives
            or S&P 500 stocks even when the S&P 500 is declining.

              Though the Fund does not normally invest directly in S&P 500
            securities, when S&P 500 derivatives appear to be overvalued
            relative to the S&P 500, the Fund may invest all of its assets in a
            "basket" of S&P 500 stocks. Individual stocks are selected based on
            an analysis of the historical correlation between the return of
            every S&P 500 stock and the return on the S&P 500 itself. PIMCO may
            employ fundamental analysis of factors such as earnings and earnings
            growth, price to earnings ratio, dividend growth, and cash flows to
            choose among stocks that satisfy the correlation tests. Stocks
            chosen for the Fund are not limited to those with any particular
            weighting in the S&P 500.

              Assets not invested in equity securities or derivatives may be
            invested in Fixed Income Instruments. The Fund may invest up to
            10% of its assets in high yield securities ("junk bonds") rated B
            or higher by Moody's or S&P, or, if unrated, determined by PIMCO
            to be of comparable quality. The Fund may invest up to 20% of its
            assets in securities denominated in foreign currencies and may
            invest beyond this limit in U.S. dollar-denominated securities of
            foreign issuers. The Fund will normally hedge at least 75% of its
            exposure to foreign currency to reduce the risk of loss due to
            fluctuations in currency exchange rates. In addition, the Fund may
            lend its portfolio securities to brokers, dealers and other
            financial institutions to earn income.

- --------------------------------------------------------------------------------
Principal   Under certain conditions, generally in a market where the value of
Risks       both S&P 500 derivatives and fixed income securities are declining,
            the Fund may experience greater losses than would be the case if it
            invested directly in a portfolio of S&P 500 stocks. Among the
            principal risks of investing in the Fund, which could adversely
            affect its net asset value, yield and total return, are:

              . Market Risk       . Interest Rate Risk       . Mortgage Risk
              . Issuer Risk       . Liquidity Risk           . Leveraging Risk
              . Derivatives Risk  . Foreign Investment Risk  . Management Risk
              . Credit Risk       . Currency Risk

            Please see "Summary of Principal Risks" following the Fund
            Summaries for a description of these and other risks of investing
            in the Fund.

Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risk of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds.

              The bar chart, the information to its right and the Average Annual
            Total Returns table show performance of the Fund's Institutional
            Class Shares, which are offered in a different prospectus. This is
            because the Fund has not offered Class D shares for a full calendar
            year. Although Class D and Institutional Class shares would have
            similar annual returns (because all the Fund's shares represent
            interests in the same portfolio of securities), Class D performance
            would be lower than Institutional Class performance because of the
            higher expenses paid by Class D shares.

              The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            date of Class D shares (4/8/98), performance is based on the
            performance of the Fund's Institutional Class shares, adjusted to
            reflect the actual 12b-1/service fees and other expenses paid by
            Class D shares. Past performance is no guarantee of future
            results.

                 Company Act of 1940. Up to 0.25% per year of the total fees
                 paid under the administration agreement may be distribution
                 and/or service (12b-1) fees. The Fund will pay a total of
                 0.65% per year under the administration agreement regardless
                 of whether a portion or none of the 0.25% authorized under
                 the plan is paid under the plan. Please see "Management of
                 the Funds--Investment Adviser and Administrator--
                 Administrative Fees" for details. The Fund intends to treat
                 any fees paid under the plan as "service fees" for purposes
                 of applicable rules of the National Association of Securities
                 Dealers, Inc. (the "NASD"). To the extent that such fees are
                 deemed not to be "service fees," Class D shareholders may,
                 depending on the length of time the shares are held, pay more
                 than the economic equivalent of the maximum front-end sales

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in the noted class of shares for the time periods
            indicated, and then redeem all your shares at the end of those
            periods. The Examples also assume that your investment has a 5%
            return each year, the reinvestment of all dividends and
            distributions, and that the Fund's operating expenses remain the
            same. Although your actual costs may be higher or lower, the
            Examples show what your costs would be based on these assumptions.

            Summary of Principal Risks

            The value of your investment in a Fund changes with the values of
            that Fund's investments. Many factors can affect those values. The
            factors that are most likely to have a material effect on a
            particular Fund's portfolio as a whole are called "principal
            risks." The principal risks of each Fund are identified in the
            Fund Summaries and are described in this section. Each Fund may be
            subject to additional principal risks and risks other than those
            described below because the types of investments made by a Fund
            can change over time. Securities and investment techniques
            mentioned in this summary and described in greater detail under
            "Characteristics and Risks of Securities and Investment
            Techniques" appear in bold type. That section and "Investment
            Objectives and Policies" in the Statement of Additional
            Information also include more information about the Funds, their
            investments and the related risks. There is no guarantee that a
            Fund will be able to achieve its investment objective.

Interest    As interest rates rise, the value of fixed income securities held
Rate Risk   by a Fund are likely to decrease. Securities with longer durations
            tend to be more sensitive to changes in interest rates, usually
            making them more volatile than securities with shorter durations.

Credit      A Fund could lose money if the issuer or guarantor of a fixed
Risk        income security, or the counterparty to a derivatives contract,
            repurchase agreement or a loan of portfolio securities, is unable
            or unwilling to make timely principal and/or interest payments, or
            to otherwise honor its obligations. Securities are subject to
            varying degrees of credit risk, which are often reflected in
            credit ratings. Municipal bonds are subject to the risk that
            litigation, legislation or other political events, local business
            or economic conditions, or the bankruptcy of the issuer could have
            a significant effect on an issuer's ability to make payments of
            principal and/or interest.

High        Funds that invest in high yield securities and unrated securities
Yield       of similar credit quality (commonly known as "junk bonds") may be
Risk        subject to greater levels of interest rate, credit and liquidity
            risk than Funds that do not invest in such securities. High yield
            securities are considered predominately speculative with respect
            to the issuer's continuing ability to make principal and interest
            payments. An economic downturn or period of rising interest rates
            could adversely affect the market for high yield securities and
            reduce a Fund's ability to sell its high yield securities
            (liquidity risk).

Market      The market price of securities owned by a Fund may go up or down,
Risk        sometimes rapidly or unpredictably. Securities may decline in
            value due to factors affecting securities markets generally or
            particular industries represented in the securities markets. The
            value of a security may decline due to general market conditions
            which are not specifically related to a particular company, such
            as real or perceived adverse economic conditions, changes in the
            general outlook for corporate earnings, changes in interest or
            currency rates or adverse investor sentiment generally. They may
            also decline due to factors which affect a particular industry or
            industries, such as labor shortages or increased production costs
            and competitive conditions within an industry. Equity securities
            generally have greater price volatility than fixed income
            securities.

Issuer      The value of a security may decline for a number of reasons which
Risk        directly relate to the issuer, such as management performance,
            financial leverage and reduced demand for the issuer's goods or
            services.

Liquidity   Liquidity risk exists when particular investments are difficult to
Risk        purchase or sell. A Fund's investments in illiquid securities may
            reduce the returns of the Fund because it may be unable to sell
            the illiquid securities at an advantageous time or price. Funds
            with principal investment strategies that involve foreign
            securities, derivatives or securities with substantial market
            and/or credit risk tend to have the greatest exposure to liquidity
            risk.

Derivatives Each Fund may use derivatives, which are financial contracts whose
Risk        value depends on, or is derived from, the value of an underlying
            asset, reference rate or index. The various derivative instruments
            that the Funds may use are referenced under "Characteristics and
            Risks of Securities and Investment Techniques--Derivatives" in
            this Prospectus and described in more detail under "Investment
            Objectives and Policies" in the Statement of Additional
            Information. The Funds typically use derivatives as a substitute
            for taking a position in the underlying asset and/or as part of a
            strategy designed to reduce exposure to other risks, such as
            interest rate or currency risk. The Funds may also use derivatives
            for leverage, in which case their use would involve leveraging
            risk. A Fund's use of derivative instruments involves risks
            different from, or possibly greater than, the risks associated
            with investing directly in securities and other traditional
            investments. Derivatives are subject to a number of risks
            described elsewhere in this section, such as liquidity risk,
            interest rate risk, market risk, credit risk and management risk.
            They also involve the risk of mispricing or improper valuation and
            the risk that

            changes in the value of the derivative may not correlate perfectly
            with the underlying asset, rate or index. A Fund investing in a
            derivative instrument could lose more than the principal amount
            invested. Also, suitable derivative transactions may not be
            available in all circumstances and there can be no assurance that
            a Fund will engage in these transactions to reduce exposure to
            other risks when that would be beneficial.

Mortgage    A Fund that purchases mortgage-related securities is subject to
Risk        certain additional risks. Rising interest rates tend to extend the
            duration of mortgage-related securities, making them more
            sensitive to changes in interest rates. As a result, in a period
            of rising interest rates, a Fund that holds mortgage-related
            securities may exhibit additional volatility. This is known as
            extension risk. In addition, mortgage-related securities are
            subject to prepayment risk. When interest rates decline, borrowers
            may pay off their mortgages sooner than expected. This can reduce
            the returns of a Fund because the Fund will have to reinvest that
            money at the lower prevailing interest rates.

Foreign     A Fund that invests in foreign securities may experience more
(Non-       rapid and extreme changes in value than a Fund that invests
U.S.)       exclusively in securities of U.S. companies. The securities
Investment  markets of many foreign countries are relatively small, with a
Risk        limited number of companies representing a small number of
            industries. Additionally, issuers of foreign securities are
            usually not subject to the same degree of regulation as U.S.
            issuers. Reporting, accounting and auditing standards of foreign
            countries differ, in some cases significantly, from U.S.
            standards. Also, nationalization, expropriation or confiscatory
            taxation, currency blockage, political changes or diplomatic
            developments could adversely affect a Fund's investments in a
            foreign country. In the event of nationalization, expropriation or
            other confiscation, a Fund could lose its entire investment in
            foreign securities. Adverse conditions in a certain region can
            adversely affect securities of other countries whose economies
            appear to be unrelated. To the extent that a Fund invests a
            significant portion of its assets in a concentrated geographic
            area like Eastern Europe or Asia, the Fund will generally have
            more exposure to regional economic risks associated with foreign
            investments.

Emerging    Foreign investment risk may be particularly high to the extent
Markets     that a Fund invests in emerging market securities of issuers based
Risk        in countries with developing economies. These securities may
            present market, credit, currency, liquidity, legal, political and
            other risks different from, or greater than, the risks of
            investing in developed foreign countries.

Currency    Funds that invest directly in foreign currencies or in securities
Risk        that trade in, and receive revenues in, foreign (non-U.S.)
            currencies are subject to the risk that those currencies will
            decline in value relative to the U.S. dollar, or, in the case of
            hedging positions, that the U.S. dollar will decline in value
            relative to the currency being hedged. Currency rates in foreign
            countries may fluctuate significantly over short periods of time
            for a number of reasons, including changes in interest rates,
            intervention (or the failure to intervene) by U.S. or foreign
            governments, central banks or supranational entities such as the
            International Monetary Fund, or by the imposition of currency
            controls or other political developments in the U.S. or abroad. As
            a result, the Fund's investments in foreign currency-denominated
            securities may reduce the returns of the Fund.

Concen-     Concentration of investments in a small number of issuers,
tration     industries or foreign currencies increases risk. The Foreign Bond,
Risk        Emerging Markets Bond, California Intermediate Municipal Bond, New
            York Intermediate Municipal Bond, and Real Return Bond Funds are
            "non-diversified," which means that they may invest a greater
            percentage of their assets in the securities of a single issuer
            (such as bonds issued by a particular state) than the other Funds.
            Funds that invest in a relatively small number of issuers are more
            susceptible to risks associated with a single economic, political
            or regulatory occurrence than a more diversified portfolio might
            be. Some of those issuers also may present substantial credit or
            other risks. Similarly, a Fund may be more sensitive to adverse
            economic, business or political developments if it invests a
            substantial portion of its assets in the bonds of similar projects
            or from issuers in the same state.

Leveraging  Certain Funds may engage in transactions that may give rise to a
Risk        form of leverage. Such transactions may include, among others,
            reverse repurchase agreements, loans of portfolios securities, and
            the use of when-issued, delayed delivery or forward commitment
            transactions. The use of derivatives may also create leveraging
            risk. To mitigate leveraging risk, PIMCO will segregate liquid
            assets or otherwise cover the transactions that may give rise to
            such risk. The use of leverage may cause a Fund to liquidate
            portfolio positions when it may not be advantageous to do so to
            satisfy its obligations or to meet segregation requirements.
            Leverage, including borrowing, may cause a Fund to be more
            volatile than if the Fund had not been leveraged. This is because
            leverage tends to exaggerate the effect of any increase or
            decrease in the value of a Fund's portfolio securities.

                                                                  Prospectus  36

Management  Each Fund is subject to management risk because it is an actively
Risk        managed investment portfolio. PIMCO and each individual portfolio
            manager will apply investment techniques and risk analyses in
            making investment decisions for the Funds, but there can be no
            guarantee that these will produce the desired results.

California  Because the California Intermediate Municipal Bond Fund
State-      concentrates its investments in California municipal bonds, the
Specific    Fund may be affected significantly by economic, regulatory or
Risk        political developments affecting the ability of California issuers
            to pay interest or repay principal. Provisions of the California
            Constitution and State statutes which limit the taxing and
            spending authority of California governmental entities may impair
            the ability of California issuers to pay principal and/or interest
            on their obligations. While California's economy is broad, its
            does have major concentrations in high technology, aerospace and
            defense-related manufacturing, trade, entertainment, real estate
            and financial services, and may be sensitive to economic problems
            affecting those industries. Future California political and
            economic developments, constitutional amendments, legislative
            measures, executive orders, administrative regulations, litigation
            and voter initiatives could have an adverse effect on the debt
            obligations of California issuers. To the extent that the Short
            Duration Municipal Income and Municipal Bond Funds concentrate
            their investements in California Municipal Bonds, the Funds will
            also be subject to California state specific risk.

New York    Because the New York Intermediate Municipal Bond Fund concentrates
State-      its investments in New York municipal bonds, the Fund may be
Specific    affected significantly by economic, regulatory or political
Risk        developments affecting the ability of New York issuers to pay
            interest or repay principal. Certain issuers of New York municipal
            bonds have experienced serious financial difficulties in recent
            years. A reoccurrence of these difficulties may impair the ability
            of certain New York issuers to pay principal or interest on their
            obligations. The financial health of New York City affects that of
            the State, and when New York City experiences financial difficulty
            it may have an adverse affect on New York municipal bonds held by
            the Fund. The growth rate of New York has recently been somewhat
            slower than the nation overall. The economic and financial
            condition of New York also may be affected by various financial,
            social, economic and political factors. To the extent that the
            Short Duration Municipal Income and Municipal Bond Funds
            concentrate their investments in New York Municipal Bonds, the
            Funds will also be subject to New York state specific risk.

            Management of the Funds

Investment  PIMCO serves as the investment adviser and the administrator
Adviser     (serving in its capacity as administrator, the "Administrator")
and         for the Funds. Subject to the supervision of the Board of
Adminis-    Trustees, PIMCO is responsible for managing the investment
trator      activities of the Funds and the Funds' business affairs and other
            administrative matters.

             PIMCO is located at 840 Newport Center Drive, Newport Beach,
            California 92660. Organized in 1971, PIMCO provides investment
            management and advisory services to private accounts of
            institutional and individual clients and to mutual funds. As of
            December 31, 1999, PIMCO had approximately $186 billion in assets
            under management.

Advisory    Each Fund pays PIMCO fees in return for providing investment
Fees        advisory services. For the fiscal year ended March 31, 1999, the
            Funds paid monthly advisory fees to PIMCO at the following annual
            rates (stated as a percentage of the average daily net assets of
            each Fund taken separately):

             The Short Duration Municipal Income, California Intermediate
            Municipal Bond, New York Intermediate Municipal Bond and
            Convertible Funds were not operational during the fiscal year
            ended March 31, 1999. The investment advisory fees for the Short
            Duration Municipal Income, California Intermediate Municipal Bond,
            New York Intermediate Municipal Bond, and Convertible Funds are at
            an annual rate of 0.20%, 0.25%, 0.25% and 0.40%, respectively,
            based upon the average daily net assets of the Fund.

Adminis-    Each Fund pays for the administrative services it requires under a
trative     fee structure which is essentially fixed. Class D shareholders of
Fees        each Fund pay an administrative fee to PIMCO, computed as a

<PAGE>

            percentage of the Fund's assets attributable in the aggregate to
            that class of shares. PIMCO, in turn, provides or procures
            administrative services for Class D shareholders and also bears
            the costs of various third-party services required by the Funds,
            including audit, custodial, portfolio accounting, legal transfer
            agency and printing costs. The result of this fee structure is an
            expense level for Class D shareholders of each Fund that, with
            limited exceptions, is precise and predictable under ordinary
            circumstances.

              PIMCO may pay financial service firms a portion of the Class D
            administrative fees in return for the firm's services (normally
            not to exceed an annual rate of 0.35% of a Fund's average daily
            net assets attributable to Class D shares purchased through such
            firms).

              For the fiscal year ended March 31, 1999, the Funds paid PIMCO
            monthly administrative fees at the following annual rates (stated

            * As described below under "12b-1 Plan for Class D Shares," the
            administration agreement includes a plan adopted in conformity
            with Rule 12b-1 under the Investment Company Act of 1940 (the
            "1940 Act") which provides for the payment of up to 0.25% of the
            Administrative Fee as reimbursement for expenses in respect of
            activities that may be deemed to be primarily intended to result
            in the sale of Class D shares. In the Fund Summaries above, the
            "Annual Fund Operating Expenses" table provided under "Fees and
            Expenses of the Fund" for each Fund shows the Administrative Fees
            rate under two separate columns entitled "Distribution and/or
            Service (12b-1) Fees" and "Other Expenses."

              The Short Duration Municipal Income, California Intermediate
            Municipal Bond, New York Intermediate Municipal Bond, Convertible
            Funds were not operational during the fiscal year ended March
            31, 1999. The administrative fees for the Short Duration Municipal
            Income, California Intermediate Municipal Bond, New York
            Intermediate Municipal Bond, and Convertible Bond Funds are at an
            annual rate of 0.35%, 0.35%, 0.35%, and 0.40%, respectively, based
            upon the average daily net assets of the Fund.

12b-1       The Funds' administration agreement includes a plan for Class D
Plan for    shares that has been adopted in conformity with the requirements
Class D     set forth in Rule 12b-1 under the 1940 Act. The plan provides that
Shares      up to 0.25% per annum of the Class D administrative fees paid
            under the administration agreement may represent reimbursement for
            expenses in respect of activities that may be deemed to be
            primarily intended to result in the sale of Class D shares. The
            principal types of activities for which such payments may be made
            are services in connection with the distribution of Class D shares
            and/or the provision of shareholder services. Because 12b-1 fees
            would be paid out of a Fund's Class D share assets on an ongoing
            basis, over time these fees would increase the cost of your
            investment in Class D shares and may cost you more than other
            types of sales charges.

            How to Buy and Sell Shares

            The following section provides basic information about how to buy,
            sell (redeem) and exchange Class D shares of the Funds.

General       .  Financial Service Firms. Broker-dealers, registered investment
Information advisers and other financial service firms provide varying
            investment products, programs or accounts, pursuant to arrangements
            with the Distributor, through which their clients may purchase and
            redeem Class D shares of the Funds. Firms will generally provide or
            arrange for the provision of some or all of the shareholder
            servicing and account maintenance services required by your account,
            including, without limitation, transfers of registration and
            dividend payee changes. Firms may also perform other functions,
            including generating confirmation statements and disbursing cash
            dividends, and may arrange with their clients for other investment
            or administrative services. Your firm may independently establish
            and charge you transaction fees and/or other additional amounts for
            such services, which may change over time. These fees and additional
            amounts could reduce your investment returns on Class D shares of
            the Funds.

              Your financial service firm may have omnibus accounts and similar
            arrangements with the Trust and may be paid for providing sub-
            transfer agency and other services. A firm may be paid for its
            services directly or indirectly by the Funds, PIMCO Advisors or an

            Fund's average daily net assets attributable to its Class D shares
            and purchased through such firm for its clients). Your firm may
            establish various minimum investment requirements for Class D shares
            of the Funds and may also establish certain privileges with respect
            to purchases, redemptions and exchanges of Class D shares or the
            reinvestment of dividends. Please contact your firm for information.

              This Prospectus should be read in connection with your firm's

              .  Calculation of Share Price and Redemption Payments. When you
            buy or sell (redeem) Class D shares of the Funds, you pay or
            receive a price equal to the NAV of the shares. NAVs are
            determined at the close of regular trading (normally 4:00 p.m.
            Eastern time) on each day the New York Stock Exchange is open. See
            "How Fund Shares Are Priced" below for details. Generally,
            purchase and redemption orders for Fund shares are processed at
            the NAV next calculated after your order is received by the
            Distributor. In addition, orders received by the Distributor from
            financial service firms after NAV is determined that day will be
            processed at that day's NAV if the orders were received by the
            firm from its customer prior to such determination and were
            transmitted to and received by the Distributor prior to its close
            of business that day (normally 7:00 p.m., Eastern time).

              The Trust does not calculate NAVs or process orders on days when
            the New York Stock Exchange is closed. If your purchase or
            redemption order is received by the Distributor on a day when the
            New York Stock Exchange is closed, it will be processed on the
            next succeeding day when the New York Stock Exchange is open
            (according to the succeeding day's NAV).

Buying      Class D shares of each Fund are continuously offered through
Shares      financial service firms, such as broker-dealers or registered
            investment advisers, with which the Distributor has an agreement for
            the use of the Funds in particular investment products, programs or
            accounts for which a fee may be charged. See "Financial Service
            Firms" above.

              You may purchase Class D shares only through your financial
            service firm. In connection with purchases, your financial service
            firm is responsible for forwarding all necessary documentation to
            the Distributor, and may charge you for such services. If you wish
            to purchase shares of the Funds directly from the Trust or the
            Distributor, you should inquire about the other classes of shares
            offered by the Trust. Please call the Distributor at 1-888-87-
            PIMCO for information about other investment options.

              Class D shares of the Funds will be held in your account with
            your financial service firm and, generally, your firm will hold
            your Class D shares in nominee or street name as your agent. In
            most cases, the Trust's transfer agent will have no information
            with respect to or control over accounts of specific Class D
            shareholders and you may obtain information about your accounts
            only through your financial service firm. In certain
            circumstances, your firm may arrange to have your shares held in
            your own name or you may subsequently become a holder of record
            for some other reason (for instance, if you terminate your
            relationship with your firm). In such circumstances, please
            contact the Distributor at 1-888-87-PIMCO for information about
            your account. In the interest of economy and convenience,
            certificates for Class D shares will not be issued.

                                                                  Prospectus  40
<PAGE>

              The Distributor, in its sole discretion, may accept or reject any
            order for purchase of Fund shares. The sale of shares will be
            suspended during any period in which the Exchange is closed for
            other than weekends or holidays, or if permitted by the rules of
            the Securities and Exchange Commission, when trading on the New
            York Stock Exchange is restricted or during an emergency which
            makes it impracticable for the Funds to dispose of their
            securities or to determine fairly the value of their net assets,
            or during any other period as permitted by the Securities and
            Exchange Commission for the protection of investors.

              .  Investment Minimums. The following investment minimums apply
            for purchases of Class D shares.

</TABLE>

              Your financial service firm may impose different investment
            minimums than the Trust. For example, if your firm maintains an
            omnibus account with a particular Fund, the firm may impose higher
            or lower investment minimums than the Trust when you invest in
            Class D shares of the Fund through your firm. Please contact your
            firm for information.

Exchanging  You may exchange your Class D shares of any Fund for Class D
Shares      shares of any other Fund or any series of PIMCO Funds: Multi-
            Manager Series that offers Class D shares. Shares are exchanged on
            the basis of their respective NAVs next calculated after your
            exchange order is received by the Distributor. Currently, the
            Trust does not charge any exchange fees or charges. Your financial
            service firm may impose various fees and charges, investment
            minimums and other requirements with respect to exchanges. Please
            contact your financial service firm to exchange your shares and
            for additional information about the exchange privilege.

              The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO, the purchase would adversely affect a Fund
            and its shareholders. In particular, a pattern of exchanges
            characteristic of "market-timing" strategies may be deemed by
            PIMCO to be detrimental to the Trust or a particular Fund.
            Currently, the Trust limits the number of "round trip" exchanges
            an investor may make. An investor makes a "round trip" exchange
            when the investor purchases shares of a particular Fund,
            subsequently exchanges those shares for shares of a different Fund
            and then exchanges back into the originally purchased Fund. The
            Trust has the right to refuse any exchange for any investor who
            completes (by making the exchange back into the shares of the
            originally purchased Fund) more than six round trip exchanges in
            any twelve-month period. Although the Trust has no current
            intention of terminating or modifying the exchange privilege other
            than as set forth in the preceding sentence, it reserves the right
            to do so at any time. Except as otherwise permitted by Securities
            and Exchange Commission regulations, the Trust will give 60 days'
            advance notice to your financial service firm of any termination
            or material modification of the exchange privilege.

Selling     You can sell (redeem) Class D shares through your financial
Shares      service firm on any day the New York Stock Exchange is open. You
            do not pay any fees or other charges to the Trust or the
            Distributor when you sell your shares, although your financial
            service firm may charge you for its services in processing your
            redemption request. Please contact your firm for details. If you
            are the holder of record of your Class D shares, you may contact
            the Distributor at 1-888-87-PIMCO for information regarding how to
            sell your shares directly to the Trust.

              Your financial service firm is obligated to transmit your
            redemption orders to the Distributor promptly and is responsible
            for ensuring that your redemption request is in proper form. Your
            financial service firm will be responsible for furnishing all
            necessary documentation to the Distributor or the Trust's transfer
            agent and may charge you for its services. Redemption proceeds
            will be forwarded to your financial service firm as promptly as
            possible and in any event within seven days after the redemption
            request is received by the Distributor in good order. Redemptions
            of Fund shares may be suspended when trading on the New York Stock
            Exchange is restricted or during an emergency which makes it
            impracticable for the Funds to dispose of their securities or to
            determine fairly the value of their net assets, or during any
            other period as permitted by the Securities and Exchange
            Commission for the protection of investors. Under these and other
            unusual circumstances, the Trust may suspend redemptions or
            postpone payment for more than seven days, as permitted by law.

Redemptions The Trust had agreed to redeem shares of each Fund solely in cash
In Kind     up to the lesser of $250,000 or 1% of the Fund's net assets during
            any 90-day period for any one shareholder. In consideration of the
            best interests of the remaining shareholders, the Trust may pay
            any redemption proceeds exceeding this amount in whole or in part
            by a distribution in kind of securities held by a Fund in lieu of
            cash. Except for Funds with a tax-efficient management strategy,
            it is highly unlikely that your shares would ever be

41  PIMCO Funds: Pacific Investment Management Series

            redeemed in kind. If your shares are redeemed in kind, you should
            expect to incur transaction costs upon the disposition of the
            securities received in the distribution.

            How Fund Shares Are Priced

              The net asset value ("NAV") of a Fund's Class D shares is
            determined by dividing the total value of a Fund's portfolio
            investments and other assets attributable to that class, less any
            liabilities, by the total number of shares outstanding of that
            class.

              For purposes of calculating NAV, portfolio securities and other
            assets for which market quotes are available are stated at market
            value. Market value is generally determined on the basis of last
            reported sales prices, or if no sales are reported, based on
            quotes obtained from a quotation reporting system, established
            market makers, or pricing services. Certain securities or
            investments for which daily market quotations are not readily
            available may be valued, pursuant to guidelines established by the
            Board of Trustees, with reference to other securities of indices.
            Short-term investments having a maturity of 60 days or less are
            generally valued at amortized cost. Exchange traded options,
            futures and options on futures are valued at the settlement price
            determined by the exchange. Other securities for which market
            quotes are not readily available are valued at fair value as
            determined in good faith by the Board of Trustees or persons
            acting at their direction.

              Investments initially valued in currencies other than the U.S.
            dollar are converted to U.S. dollars using exchange rates obtained
            from pricing services. As a result, the NAV of a Fund's shares may
            be affected by changes in the value of currencies in relation to
            the U.S. dollar. The value of securities traded in markets outside
            the United States or denominated in currencies other than the U.S.
            dollar may be affected significantly on a day that the New York
            Stock Exchange is closed and an investor is not able to purchase,
            redeem or exchange shares.

              Fund shares are valued at the close of regular trading (normally
            4:00 p.m., Eastern time)(the "NYSE Close") on each day that the
            New York Stock Exchange is open. For purposes of calculating the
            NAV, the Funds normally use pricing data for domestic equity
            securities received shortly after the NYSE Close and do not
            normally take into account trading, clearances or settlements that
            take place after the NYSE Close. Domestic fixed income and foreign
            securities are normally priced using data reflecting the earlier
            closing of the principal markets for those securities. Information
            that becomes known to the Funds or its agents after the NAV has
            been calculated on a particular day will not generally be used to
            retroactively adjust the price of a security or the NAV determined
            earlier that day.

              In unusual circumstances, instead of valuing securities in the
            usual manner, the Funds may value securities at fair value or
            estimate their value as determined in good faith by the Board of
            Trustees, generally based upon recommendations provided by PIMCO.
            Fair valuation may also be used if extraordinary events occur after
            the close of the relevant market but prior to the NYSE Close.

            Fund Distributions

              Each Fund distributes substantially all of its net investment
            income to shareholders in the form of dividends. You begin earning
            dividends on Fund shares the day after the Trust receives your
            purchase payment. Dividends paid by each Fund with respect to each
            class of shares are calculated in the same manner and at the same
            time. The following shows when each Fund intends to declare and
            distribute income dividends to shareholders of record.

              In addition, each Fund distributes any net capital gains it earns
            from the sale of portfolio securities to shareholders no less
            frequently than annually. Net short-term capital gains may be paid
            more frequently.

                                                                  Prospectus  42

            You can choose from the following distribution options:

              . Reinvest all distributions in additional Class D shares of
            your Fund at NAV. This will be done unless you elect another
            option.

              . Invest all distributions in Class D shares of any other Fund
            or any series of PIMCO Funds: Multi-Manager Series which offers
            Class D shares at NAV. You must have an account existing in the
            Fund or series selected for investment with the identical
            registered name. This option must be elected when your account is
            set up.

              . Receive all distributions in cash (either paid directly to you
            or credited to your account with your financial service firm).
            This option must be elected when your account is set up.

              Your financial service firm may offer additional distribution
            reinvestment programs or options. Please contact your firm for
            details.

              You do not pay any sales charges on shares you receive through
            the reinvestment of Fund distributions. If you elect to receive
            Fund distributions in cash and the postal or other delivery
            service is unable to deliver checks to your address of record, the
            Trust's Transfer Agent will hold the returned checks for your
            benefit in a non-interest bearing account.

            Tax Consequences

              . Taxes on Fund distributions. If you are subject to U.S. federal
            income tax, you will be subject to tax on Fund distributions whether
            you received them in cash or reinvested in additional shares of the
            Funds. For federal income tax purposes, Fund distributions will be
            taxable to you as either ordinary income or capital gains.

              Fund dividends (i.e., distributions of investment income) are
            taxable to you as ordinary income. Federal taxes on Fund
            distributions of gains are determined by how long the Fund owned
            the investments that generated the gains, rather than how long you
            have owned your shares. Distributions of gains from investments
            that a Fund owned for more than 12 months will generally be
            taxable to you as capital gains. Distributions of gains from
            investments that the Fund owned for 12 months or less will
            generally be taxable to you as ordinary income.

              Fund distributions are taxable to you even if they are paid from
            income or gains earned by a Fund prior to your investment and thus
            were included in the price you paid for your shares. For example,
            if you purchase shares on or just before the record date of a Fund
            distribution, you will pay full price for the shares and may
            receive a portion of your investment back as a taxable
            distribution.

              . Taxes when you sell (redeem) or exchange your shares. Any gain
            resulting from the sale of Fund shares will generally be subject
            to federal income tax. When you exchange shares of a Fund for
            shares of another series, the transaction will be treated as a
            sale of the Fund shares for these purposes, and any gain on those
            shares will generally be subject to federal income tax.

              . Consult your tax advisor about other possible tax consequences.
            This is a summary of certain federal income tax consequences of
            investing in a Fund. You should consult your tax advisor for more
            information on your own tax situation, including possible state,
            local and foreign tax consequences.

              . A Note on the Real Return Bond Fund. Periodic adjustments for
            inflation to the principal amount of an inflation-indexed bond may
            give rise to original issue discount, which will be includable in
            the Fund's gross income. Due to original issue discount, the Fund
            may be required to make annual distributions to shareholders that
            exceed the cash received, which may cause the Fund to liquidate
            certain investments when it is not advantageous to do so. Also, if
            the principal value of an inflation-indexed bond is adjusted
            downward due to deflation, amounts previously distributed in the
            taxable year may be characterized in some circumstances as a
            return of capital.

              . A Note on the Municipal Funds. Dividends paid to shareholders
            of the Municipal Funds and derived from Municipal Bond interest
            are expected to be designated by the Funds as "exempt-interest
            dividends" and you may generally exclude such dividends from gross
            income for federal income tax purposes. The federal tax exemption
            for "exempt-interest dividends" from Municipal Bonds does not
            necessarily result in the exemption of such dividends from state
            and local taxes, although the California Intermediate Municipal
            Bond Fund and the New York Intermediate Municipal Bond Fund intend
            to arrange their affairs so that a portion of such distributions
            will be exempt from state taxes in

43  PIMCO Funds: Pacific Investment Management Series
<PAGE>

            the respective state. Each Municipal Fund may invest a portion of
            its assets in securities that generate income that is not exempt
            from federal or state income tax. Dividends derived from taxable
            interest or capital gains will be subject to federal income tax.
            The interest on "private activity" bonds is a tax-preference item
            for purposes of the federal alternative minimum tax. As a result,
            if you are subject to the alternative minimum tax, income derived
            from "private activity" bonds will not be exempt from federal
            income tax. The Municipal Funds seek to produce income that is
            generally exempt from federal income tax and will not benefit
            investors in tax-sheltered retirement plans or individuals not
            subject to federal income tax. Further, the California and New
            York Intermediate Municipal Bond Funds seek to produce income that
            is generally exempt from the relevant state's income tax and will
            not benefit individuals that are not subject to that state's
            income tax.

              This section relates only to federal income tax; the consequences
            under other tax laws may differ. Shareholders should consult their
            tax advisors as to the possible application of foreign, state and

            Characteristics and Risks of Securities and Investment Techniques

            This section provides additional information about some of the
            principal investments and related risks of the Funds described
            under "Summary Information" above. It also describes
            characteristics and risks of additional securities and investment
            techniques that may be used by the Funds from time to time. Most
            of these securities and investment techniques are discretionary,
            which means that PIMCO can decide whether to use them or not. This
            Prospectus does not attempt to disclose all of the various types
            of securities and investment techniques that may be used by the
            Funds. As with any mutual fund, investors in the Funds rely on the
            professional investment judgment and skill of PIMCO and the
            individual portfolio managers. Please see "Investment Objectives
            and Policies" in the Statement of Additional Information for more
            detailed information about the securities and investment
            techniques described in this section and about other strategies
            and techniques that may be used by the Funds.

Securities  Most of the Funds in this prospectus seek maximum total return.
Selection   The total return sought by a Fund consists of both income earned
            on a Fund's investments and capital appreciation, if any, arising
            from increases in the market value of a Fund's holdings. Capital
            appreciation of fixed income securities generally results from
            decreases in market interest rates or improving credit
            fundamentals for a particular market sector or security.

              In selecting securities for a Fund, PIMCO develops an outlook for
            interest rates, currency exchange rates and the economy; analyzes
            credit and call risks, and uses other security selection
            techniques. The proportion of a Fund's assets committed to
            investment in securities with particular characteristics (such as
            quality, sector, interest rate or maturity) varies based on
            PIMCO's outlook for the U.S. economy and the economies of other
            countries in the world, the financial markets and other factors.

              PIMCO attempts to identify areas of the bond market that are
            undervalued relative to the rest of the market. PIMCO identifies
            these areas by grouping bonds into the following sectors: money
            markets, governments, corporates, mortgages, asset-backed and
            international. Sophisticated proprietary software then assists in
            evaluating sectors and pricing specific securities. Once
            investment opportunities are identified, PIMCO will shift assets
            among sectors depending upon changes in relative valuations and
            credit spreads. There is no guarantee that PIMCO's security
            selection techniques will produce the desired results.

U.S.        U.S. Government Securities are obligations of, or guaranteed by,
Government  the U.S. Government, its agencies or instrumentalities. U.S.
Securities  Government Securities are subject to market and interest rate
            risk, and may be subject to varying degrees of credit risk. U.S.
            Government Securities include zero coupon securities, which tend
            to be subject to greater market risk than interest-paying
            securities of similar maturities.

Corporate   Corporate debt securities are subject to the risk of the issuer's
Debt        inability to meet principal and interest payments on the
Securities  obligation and may also be subject to price volatility due to such
            factors as interest rate sensitivity, market perception of the
            creditworthiness of the issuer and general market liquidity. When
            interest rates rise, the value of corporate debt securities can be
            expected to decline. Debt securities with longer maturities tend
            to be more sensitive to interest rate movements than those with
            shorter maturities.

                                                                  Prospectus  44
<PAGE>

Variable    Variable and floating rate securities provide for a periodic
and         adjustment in the interest rate paid on the obligations. Each
Floating    Fixed Income Fund may invest in floating rate debt instruments
Rate        ("floaters") and (except the Municipal Bond Fund) engage in credit
Securities  spread trades. While floaters provide a certain degree of
            protection against rises in interest rates, a Fund will
            participate in any declines in interest rates as well. Each Fixed
            Income Fund (except the Municipal Bond Fund) may also invest in
            inverse floating rate debt instruments ("inverse floaters"). An
            inverse floater may exhibit greater price volatility than a fixed
            rate obligation of similar credit quality. A Fund may not invest
            more than 5% of its assets in any combination of inverse floater,
            interest only, or principal only securities.

Foreign     Investing in foreign securities involves special risks and
(Non-U.S.)  considerations not typically associated with investing in U.S.
Securities  securities. Shareholders should consider carefully the substantial
            risks involved for Funds that invest in securities issued by foreign
            companies and governments of foreign countries. These risks include:
            differences in accounting, auditing and financial reporting
            standards; generally higher commission rates on foreign portfolio
            transactions; the possibility of nationalization, expropriation or
            confiscatory taxation; adverse changes in investment or exchange
            control regulations; and political instability. Individual foreign
            economies may differ favorably or unfavorably from the U.S. economy
            in such respects as growth of gross domestic product, rates of
            inflation, capital reinvestment, resources, self-sufficiency and
            balance of payments position. The securities markets, values of
            securities, yields and risks associated with foreign securities
            markets may change independently of each other. Also, foreign
            securities and dividends and interest payable on those securities
            may be subject to foreign taxes, including taxes withheld from
            payments on those securities. Foreign securities often trade with
            less frequency and volume than domestic securities and therefore may
            exhibit greater price volatility. Investments in foreign securities
            may also involve higher custodial costs than domestic investments
            and additional transaction costs with respect to foreign currency
            conversions. Changes in foreign exchange rates also will affect the
            value of securities denominated or quoted in foreign currencies.

              Certain Funds also may invest in sovereign debt issued by
            governments, their agencies or instrumentalities, or other
            government-related entities. Holders of sovereign debt may be
            requested to participate in the rescheduling of such debt and to
            extend further loans to governmental entities. In addition, there
            is no bankruptcy proceeding by which defaulted sovereign debt may
            be collected.

              . Emerging Market Securities. The Emerging Markets Bond Fund
            invests primarily in securities of issuers based in countries with
            developing (or "emerging market") economies, while the Short-Term
            and Low Duration Funds may invest up to 5% of their assets in such
            securities economies, and each remaining Fund that may invest in
            foreign securities may invest up to 10% of its assets in such
            securities. Investing in emerging market securities imposes risks
            different from, or greater than, risks of investing in domestic
            securities or in foreign, developed countries. These risks
            include: smaller market capitalization of securities markets,
            which may suffer periods of relative illiquidity; significant
            price volatility; restrictions on foreign investment; possible
            repatriation of investment income and capital. In addition,
            foreign investors may be required to register the proceeds of
            sales; future economic or political crises could lead to price
            controls, forced mergers, expropriation or confiscatory taxation,
            seizure, nationalization, or creation of government monopolies.
            The currencies of emerging market countries may experience
            significant declines against the U.S. dollar, and devaluation may
            occur subsequent to investments in these currencies by a Fund.
            Inflation and rapid fluctuations in inflation rates have had, and
            may continue to have, negative effects on the economies and
            securities markets of certain emerging market countries.

              Additional risks of emerging markets securities may include:
            greater social, economic and political uncertainty and instability;
            more substantial governmental involvement in the economy; less
            governmental supervision and regulation; unavailability of currency
            hedging techniques; companies that are newly organized and small;
            differences in auditing and financial reporting standards, which may
            result in unavailability of material information about issuers; and
            less developed legal systems. In addition, emerging securities
            markets may have different clearance and settlement procedures,
            which may be unable to keep pace with the volume of securities
            transactions or otherwise make it difficult to engage in such
            transactions. Settlement problems may cause a Fund to miss
            attractive investment opportunities, hold a portion of its assets in
            cash pending investment, or be delayed in disposing of a portfolio
            security. Such a delay could result in possible liability to a
            purchaser of the security.

              Each Fixed Income Fund (except the Municipal Bond Fund) may invest
            in Brady Bonds, which are securities created through the exchange of
            existing commercial bank loans to sovereign entities for new
            obligations in connection with a debt restructuring. Investments in
            Brady Bonds may be viewed as speculative. Brady Bonds acquired by a
            Fund may be subject to restructuring arrangements or to requests for
            new credit, which may cause the Fund to suffer a loss of interest or
            principal on any of its holdings.

45  PIMCO Funds: Pacific Investment Management Series
<PAGE>

Foreign     A Fund that invests directly in foreign currencies or in
(Non-U.S.)  securities that trade in, or receive revenues in, foreign
Currencies  currencies will be subject to currency risk. Foreign currency
            exchange rates may fluctuate significantly over short periods of
            time. They generally are determined by supply and demand in the
            foreign exchange markets and the relative merits of investments in
            different countries, actual or perceived changes in interest rates
            and other complex factors. Currency exchange rates also can be
            affected unpredictably by intervention (or the failure to intervene)
            by U.S. or foreign governments or central banks, or by currency
            controls or political developments. For example, significant
            uncertainty surrounds the recent introduction of the euro (a common
            currency unit for the European Union) in January 1999 and the effect
            it may have on the value of securities denominated in local European
            currencies. These and other currencies in which the Funds' assets
            are denominated may be devalued against the U.S. dollar, resulting
            in a loss to the Funds.

              . Foreign Currency Transactions. Funds that invest in securities
            denominated in foreign currencies may enter into forward foreign
            currency exchange contracts and invest in foreign currency futures
            contracts and options on foreign currencies and futures. A forward
            foreign currency exchange contract, which involves an obligation to
            purchase or sell a specific currency at a future date at a price set
            at the time of the contract, reduces a Fund's exposure to changes in
            the value of the currency it will deliver and increases its exposure
            to changes in the value of the currency it will receive for the
            duration of the contract. The effect on the value of a Fund is
            similar to selling securities denominated in one currency and
            purchasing securities denominated in another currency. A contract to
            sell foreign currency would limit any potential gain which might be
            realized if the value of the hedged currency increases. A Fund may
            enter into these contracts to hedge against foreign exchange risk,
            to increase exposure to a foreign currency or to shift exposure to
            foreign currency fluctuations from one currency to another. Suitable
            hedging transactions may not be available in all circumstances and
            there can be no assurance that a Fund will engage in such
            transactions at any given time or from time to time. Also, such
            transactions may not be successful and may eliminate any chance for
            a Fund to benefit from favorable fluctuations in relevant foreign
            currencies. A Fund may use one currency (or a basket of currencies)
            to hedge against adverse changes in the value of another currency
            (or a basket of currencies) when exchange rates between the two
            currencies are positively correlated. The Fund will segregate assets
            determined to be liquid by PIMCO in accordance with procedures
            established by the Board of Trustees to cover its obligations under
            forward foreign currency exchange contracts entered into for non-
            hedging purposes.

High        Securities rated lower than Baa by Moody's Investors Service, Inc.
Yield       ("Moody's") or lower than BBB by Standard & Poor's Ratings
Securities  Services ("S&P") are sometimes referred to as "high yield" or
            "junk" bonds. Investing in high yield securities involves special
            risks in addition to the risks associated with investments in
            higher-rated fixed income securities. While offering a greater
            potential opportunity for capital appreciation and higher yields,
            high yield securities typically entail greater potential price
            volatility and may be less liquid than higher-rated securities.
            High yield securities may be regarded as predominately speculative
            with respect to the issuer's continuing ability to meet principal
            and interest payments. They may also be more susceptible to real
            or perceived adverse economic and competitive industry conditions
            than higher-rated securities.

              . Credit Ratings and Unrated Securities. Rating agencies are
            private services that provide ratings of the credit quality of
            fixed income securities, including convertible securities.
            Appendix A to this Prospectus describes the various ratings
            assigned to fixed income securities by Moody's and S&P. Ratings
            assigned by a rating agency are not absolute standards of credit
            quality and do not evaluate market risks. Rating agencies may fail
            to make timely changes in credit ratings and an issuer's current
            financial condition may be better or worse than a rating
            indicates. A Fund will not necessarily sell a security when its
            rating is reduced below its rating at the time of purchase. PIMCO
            does not rely solely on credit ratings, and develops its own
            analysis of issuer credit quality.

              A Fund may purchase unrated securities (which are not rated by a
            rating agency) if its portfolio manager determines that the security
            is of comparable quality to a rated security that the Fund may
            purchase. Unrated securities may be less liquid than comparable
            rated securities and involve the risk that the portfolio manager may
            not accurately evaluate the security's comparative credit rating.
            Analysis of the creditworthiness of issuers of high yield securities
            may be more complex than for issuers of higher-quality fixed income
            securities. To the extent that a Fund invests in high yield and/or
            unrated securities, the Fund's success in achieving its investment
            objective may depend more heavily on the portfolio manager's
            creditworthiness analysis than if the Fund invested exclusively in
            higher-quality and rated securities.

Inflation-  Inflation-indexed bonds are fixed income securities whose
Indexed     principal value is periodically adjusted according to the rate of
Bonds       inflation. If the index measuring inflation falls, the principal
            value of inflation-indexed bonds will be adjusted downward, and
            consequently the interest payable on these securities

                                                                  Prospectus  46
<PAGE>

            (calculated with respect to a smaller principal amount) will be
            reduced. Repayment of the original bond principal upon maturity
            (as adjusted for inflation) is guaranteed in the case of U.S.
            Treasury inflation-indexed bonds. For bonds that do not provide a
            similar guarantee, the adjusted principal value of the bond repaid
            at maturity may be less than the original principal. The value of
            inflation-indexed bonds is expected to change in response to
            changes in real interest rates. Real interest rates are tied to
            the relationship between nominal interest rates and the rate of
            inflation. If nominal interest rates increase at a faster rate
            than inflation, real interest rates may rise, leading to a
            decrease in value of inflation-indexed bonds. Short-term increases
            in inflation may lead to a decline in value. Any increase in the
            principal amount of an inflation-indexed bond will be considered
            taxable ordinary income, even though investors do not receive
            their principal until maturity.

Derivatives Each Fund may, but is not required to, use derivative instruments
            for risk management purposes or as part of its investment
            strategies. Generally, derivatives are financial contracts whose
            value depends upon, or is derived from, the value of an underlying
            asset, reference rate or index, and may relate to stocks, bonds,
            interest rates, currencies or currency exchange rates, commodities,
            and related indexes. Examples of derivative instruments include
            options contracts, futures contracts, options on futures contracts
            and swap agreements. The Municipal Bond Fund may not enter into swap
            agreements or purchase or sell options relating to foreign
            currencies. Each Fund (except the Municipal Bond Fund) may invest
            some or all of its assets in derivative instruments. A portfolio
            manager may decide not to employ any of these strategies and there
            is no assurance that any derivatives strategy used by a Fund will
            succeed. A description of these and other derivative instruments
            that the Funds may use are described under "Investment Objectives
            and Policies" in the Statement of Additional Information.

              A Fund's use of derivative instruments involves risks different
            from, or possibly greater than, the risks associated with investing
            directly in securities and other more traditional investments. A
            description of various risks associated with particular derivative
            instruments is included in "Investment Objectives and Policies" in
            the Statement of Additional Information. The following provides a
            more general discussion of important risk factors relating to all
            derivative instruments that may be used by the Funds.

              Management Risk. Derivative products are highly specialized
            instruments that require investment techniques and risk analyses
            different from those associated with stocks and bonds. The use of
            a derivative requires an understanding not only of the underlying
            instrument but also of the derivative itself, without the benefit
            of observing the performance of the derivative under all possible
            market conditions.

              Credit Risk. The use of a derivative instrument involves the risk
            that a loss may be sustained as a result of the failure of another
            party to the contract (usually referred to as a "counterparty") to
            make required payments or otherwise comply with the contract's
            terms.

              Liquidity Risk. Liquidity risk exists when a particular derivative
            instrument is difficult to purchase or sell. If a derivative
            transaction is particularly large or if the relevant market is
            illiquid (as is the case with many privately negotiated
            derivatives), it may not be possible to initiate a transaction or
            liquidate a position at an advantageous time or price.

              Leverage Risk. Because many derivatives have a leverage component,
            adverse changes in the value or level of the underlying asset,
            reference rate or index can result in a loss substantially greater
            than the amount invested in the derivative itself. Certain
            derivatives have the potential for unlimited loss, regardless of the
            size of the initial investment. When a Fund uses derivatives for
            leverage, investments in that Fund will tend to be more volatile,
            resulting in larger gains or losses in response to market changes.
            To limit leverage risk, each Fund will segregate assets determined
            to be liquid by PIMCO in accordance with procedures established by
            the Board of Trustees (or, as permitted by applicable regulation,
            enter into certain offsetting positions) to cover its obligations
            under derivative instruments.

              Lack of Availability. Because the markets for certain derivative
            instruments (including markets located in foreign countries) are
            relatively new and still developing, suitable derivatives
            transactions may not be available in all circumstances for risk
            management or other purposes. There is no assurance that a Fund
            will engage in derivatives transactions at any time or from time
            to time. A Fund's ability to use derivatives may also be limited
            by certain regulatory and tax considerations.

              Market and Other Risks. Like most other investments, derivative
            instruments are subject to the risk that the market value of the
            instrument will change in a way detrimental to a Fund's interest.
            If a portfolio manager incorrectly forecasts the values of
            securities, currencies or interest rates or other economic factors
            in using derivatives for a Fund, the Fund might have been in a
            better position if it had not entered into the transaction at all.
            While some strategies involving derivative instruments can

47  PIMCO Funds: Pacific Investment Management Series
<PAGE>

            reduce the risk of loss, they can also reduce the opportunity for
            gain or even result in losses by offsetting favorable price
            movements in other Fund investments. A Fund may also have to buy
            or sell a security at a disadvantageous time or price because the
            Fund is legally required to maintain offsetting positions or asset
            coverage in connection with certain derivatives transactions.

              Other risks in using derivatives include the risk of mispricing
            or improper valuation of derivatives and the inability of
            derivatives to correlate perfectly with underlying assets, rates
            and indexes. Many derivatives, in particular privately negotiated
            derivatives, are complex and often valued subjectively. Improper
            valuations can result in increased cash payment requirements to
            counterparties or a loss of value to a Fund. Also, the value of
            derivatives may not correlate perfectly, or at all, with the value
            of the assets, reference rates or indexes they are designed to
            closely track. In addition, a Fund's use of derivatives may cause
            the Fund to realize higher amounts of short-term capital gains
            (generally taxed at ordinary income tax rates) than if the Fund
            had not used such instruments.

Convertible Each Fund may invest in convertible securities. Convertible
Securities  securities are generally preferred stocks and other securities,
            including fixed income securities and warrants, that are convertible
            into or exercisable for common stock at a stated price or rate. The
            price of a convertible security will normally vary in some
            proportion to changes in the price of the underlying common stock
            because of this conversion or exercise feature. However, the value
            of a convertible security may not increase or decrease as rapidly as
            the underlying common stock. A convertible security will normally
            also provide income and is subject to interest rate risk.
            Convertible securities may be lower-rated securities subject to
            greater levels of credit risk. A Fund may be forced to convert a
            security before it would otherwise choose, which may have an adverse
            effect on the Fund's ability to achieve its investment objective.

              While the Fixed Income Funds intend to invest primarily in fixed
            income securities, each may invest in convertible securities or
            equity securities. While some countries or companies may be
            regarded as favorable investments, pure fixed income opportunities
            may be unattractive or limited due to insufficient supply, or
            legal or technical restrictions. In such cases, a Fund may
            consider equity securities or convertible securities to gain
            exposure to such investments.

Mortgage-   Each Fund may invest in mortgage- or other asset-backed
Related     securities. Except for the Short Duration Municipal Income,
and Other   Municipal Bond, California Intermediate Municipal Bond, New York
Asset-      Intermediate Municipal Bond and Convertible Funds, each Fund may
Backed      invest all of its assets in such securities. The Convertible Fund
Securities  may invest up to 35% of its assets in such securities. Mortgage-
            related securities include mortgage pass-through securities,
            collateralized mortgage obligations ("CMOs"), commercial mortgage-
            backed securities, mortgage dollar rolls, CMO residuals, stripped
            mortgage-backed securities ("SMBSs") and other securities that
            directly or indirectly represent a participation in, or are
            secured by and payable from, mortgage loans on real property.

              The value of some mortgage- or asset-backed securities may be
            particularly sensitive to changes in prevailing interest rates.
            Early repayment of principal on some mortgage-related securities may
            expose a Fund to a lower rate of return upon reinvestment of
            principal. When interest rates rise, the value of a mortgage-related
            security generally will decline; however, when interest rates are
            declining, the value of mortgage-related securities with prepayment
            features may not increase as much as other fixed income securities.
            The rate of prepayments on underlying mortgages will affect the
            price and volatility of a mortgage-related security, and may shorten
            or extend the effective maturity of the security beyond what was
            anticipated at the time of purchase. If unanticipated rates of
            prepayment on underlying mortgages increase the effective maturity
            of a mortgage-related security, the volatility of the security can
            be expected to increase. The value of these securities may fluctuate
            in response to the market's perception of the creditworthiness of
            the issuers. Additionally, although mortgages and mortgage-related
            securities are generally supported by some form of government or
            private guarantee and/or insurance, there is no assurance that
            private guarantors or insurers will meet their obligations.

              One type of SMBS has one class receiving all of the interest from
            the mortgage assets (the interest-only, or "IO" class), while the
            other class will receive all of the principal (the principal-only,
            or "PO" class). The yield to maturity on an IO class is extremely
            sensitive to the rate of principal payments (including prepayments)
            on the underlying mortgage assets, and a rapid rate of principal
            payments may have a material adverse effect on a Fund's yield to
            maturity from these securities. A Fund may not invest more than 5%
            of its assets in any combination of IO, PO, or inverse floater
            securities. The Funds may invest in other asset-backed securities
            that have been offered to investors.

Municipal   Municipal bonds are generally issued by states and local
Bonds       governments and their agencies, authorities and other
            instrumentalities. Municipal bonds are subject to interest rate,
            credit and market risk. The ability of an issuer to make payments
            could be affected by litigation, legislation or other political
            events or the bankruptcy of the issuer. Lower rated municipal
            bonds are subject to greater credit and market

                                                                 Prospectus  48
<PAGE>

            risk than higher quality municipal bonds. The types of municipal
            bonds in which the Funds may invest include municipal lease
            obligations. The Funds may also invest in securities issued by
            entities whose underlying assets are municipal bonds.

Loan        Certain Funds may invest in fixed- and floating-rate loans, which
Participa-  investments generally will be in the form of loan participations
tions and   and assignments of portions of such loans. Participations and
Assignments assignments involve special types of risk, including credit risk,
            interest rate risk, liquidity risk, and the risks of being a
            lender. If a Fund purchases a participation, it may only be able
            to enforce its rights through the lender, and may assume the
            credit risk of the lender in addition to the borrower.

Delayed     The Funds (except the Municipal Bond Fund) may also enter into, or
Funding     acquire participations in, delayed funding loans and revolving
Loans and   credit facilities, in which a lender agrees to make loans up to a
Revolving   maximum amount upon demand by the borrower during a specified
Credit      term. These commitments may have the effect of requiring a Fund to
Facilities  increase its investment in a company at a time when it might not
            otherwise decide to do so (including at a time when the company's
            financial condition makes it unlikely that such amounts will be
            repaid). To the extent that a Fund is committed to advance
            additional funds, it will segregate assets determined to be liquid
            by PIMCO in accordance with procedures established by the Board of
            Trustees in an amount sufficient to meet such commitments. Delayed
            funding loans and revolving credit facilities are subject to
            credit, interest rate and liquidity risk and the risks of being a
            lender.

Loans of    For the purpose of achieving income, each Fund may lend its
Portfolio   portfolio securities to brokers, dealers, and other financial
Securities  institutions provided a number of conditions are satisfied,
            including that the loan is fully collateralized. Please see
            "Investment Objectives and Policies" in the Statement of
            Additional Information for details. When a Fund lends portfolio
            securities, its investment performance will continue to reflect
            changes in the value of the securities loaned, and the Fund will
            also receive a fee or interest on the collateral. Securities
            lending involves the risk of loss of rights in the collateral or
            delay in recovery of the collateral if the borrower fails to
            return the security loaned or becomes insolvent. A Fund may pay
            lending fees to a party arranging the loan.

Short       Each Fund (except the High Yield and StocksPLUS Funds) may make
Sales       short sales as part of its overall portfolio management strategies
            or to offset a potential decline in value of a security. A short
            sale involves the sale of a security that is borrowed from a
            broker or other institution to complete the sale. For these
            purposes, a Fund may also hold or have the right to acquire
            securities which, without the payment of any further
            consideration, are convertible into or exchangeable for the
            securities sold short. Short sales expose a Fund to the risk that
            it will be required to acquire, convert or exchange securities to
            replace the borrowed securities (also known as "covering" the
            short position) at a time when the securities sold short have
            appreciated in value, thus resulting in a loss to the Fund. A Fund
            making a short sale (other than a "short sale against the box")
            must segregate assets determined to be liquid by PIMCO in
            accordance with procedures established by the Board of Trustees or
            otherwise cover its position in a permissible manner.

When-       Each Fund may purchase securities which it is eligible to purchase
Issued,     on a when-issued basis, may purchase and sell such securities for
Delayed     delayed delivery and may make contracts to purchase such
Delivery    securities for a fixed price at a future date beyond normal
and         settlement time (forward commitments). When-issued transactions,
Forward     delayed delivery purchases and forward commitments involve a risk
Commitment  of loss if the value of the securities declines prior to the
Trans-      settlement date. This risk is in addition to the risk that the
actions     Fund's other assets will decline in the value. Therefore, these
            transactions may result in a form of leverage and increase a
            Fund's overall investment exposure. Typically, no income accrues
            on securities a Fund has committed to purchase prior to the time
            delivery of the securities is made, although a Fund may earn
            income on securities it has segregated to cover these positions.

Repurchase  Each Fund may enter into repurchase agreements, in which the Fund
Agreements  purchases a security from a bank or broker-dealer and agrees to
            repurchase the security at the Fund's cost plus interest within a
            specified time. If the party agreeing to repurchase should
            default, the Fund will seek to sell the securities which it holds.
            This could involve procedural costs or delays in addition to a
            loss on the securities if their value should fall below their
            repurchase price. Repurchase agreements maturing in more than
            seven days are considered illiquid securities.

Reverse     Each Fund may enter into reverse repurchase agreements and dollar
Repurchase  rolls, subject to a Fund's limitations on borrowings. A reverse
Agreements, repurchase agreement or dollar roll involves the sale of a
Dollar      security by a Fund and its agreement to repurchase the instrument
Rolls And   at a specified time and price, and may be considered a form of
Other       borrowing for some purposes. A Fund will segregate assets
Borrowings  determined to be liquid by PIMCO in accordance with procedures
            established by the Board of Trustees or otherwise cover its
            obligations under reverse repurchase agreements, dollar rolls and
            other borrowings. A Fund also may borrow money

            for investment purposes subject to any policies of the Fund
            currently described in this Prospectus or in the Statement of
            Additional Information. Reverse repurchase agreements, dollar
            rolls and other forms of borrowings may create leveraging risk for
            a Fund.

Event-      Each Fixed Income Fund and the Strategic Balanced and StocksPLUS
Linked      Funds may invest in "event-linked bonds," which are fixed income
Bonds       securities for which the return of principal and payment of
            interest is contingent on the non-occurrence of a specific
            "trigger" event, such as a hurricane, earthquake, or other
            physical or weather-related phenomenon. If a trigger event occurs,
            a Fund may lose a portion or all of its principal invested in the
            bond. Event-linked bonds often provide for an extension of
            maturity to process and audit loss claims where a trigger event
            has, or possibly has, occurred. An extension of maturity may
            increase volatility. Event-linked bonds may also expose the Fund
            to certain unanticipated risks including credit risk, adverse
            regulatory or jurisdictional interpretations, and adverse tax
            consequences. Event-linked bonds may also be subject to liquidity
            risk.

Portfolio   The length of time a Fund has held a particular security is not
Turnover    generally a consideration in investment decisions. A change in the
            securities held by a Fund is known as "portfolio turnover." Each
            Fund may engage in frequent and active trading of portfolio
            securities to achieve its investment objective, particularly
            during periods of volatile market movements. High portfolio
            turnover (e.g., over 100%) involves correspondingly greater
            expenses to a Fund, including brokerage commissions or dealer
            mark-ups and other transaction costs on the sale of securities and
            reinvestments in other securities. Such sales may also result in
            realization of taxable capital gains, including short-term capital
            gains (which are generally taxed at ordinary income tax rates).
            The trading costs and tax effects associated with portfolio
            turnover may adversely affect a Fund's performance.

Illiquid    Each Fund may invest up to 15% of its net assets in illiquid
Securities  securities. Certain illiquid securities may require pricing at
            fair value as determined in good faith under the supervision of
            the Board of Trustees. A portfolio manager may be subject to
            significant delays in disposing of illiquid securities, and
            transactions in illiquid securities may entail registration
            expenses and other transaction costs that are higher than those
            for transactions in liquid securities. The term "illiquid
            securities" for this purpose means securities that cannot be
            disposed of within seven days in the ordinary course of business
            at approximately the amount at which a Fund has valued the
            securities. Restricted securities, i.e., securities subject to
            legal or contractual restrictions on resale, may be illiquid.
            However, some restricted securities (such as securities issued
            pursuant to Rule 144A under the Securities Act of 1933 and certain
            commercial paper) may be treated as liquid, although they may be
            less liquid than registered securities traded on established
            secondary markets.

Investment  Each Fund may invest up to 10% of its assets in securities of
in Other    other investment companies, such as closed-end management
Investment  investment companies, or in pooled accounts or other investment
Companies   vehicles which invest in foreign markets. As a shareholder of an
            investment company, a Fund may indirectly bear service and other
            fees which are in addition to the fees the Fund pays its service
            providers.

Year 2000   Many of the services provided to the Funds depend on the smooth
Readiness   functioning of computer systems. Some systems in use today cannot
Disclosure  distinguish between the year 1900 and the year 2000. Should any of
            the service systems fail to process information properly, this
            could have an adverse impact on the Funds' operations and services
            provided to shareholders. PIMCO has surveyed the Funds' material
            service providers and believes that, on the basis of the
            information supplied, that the service providers will not be
            materially adversely affected by the so-called "year 2000
            problem." However, there can be no assurance that the problem will
            be corrected in all respects and that the Funds' operations and
            services provided to shareholders will not be adversely affected,
            nor can there be any assurance that the year 2000 problem will not
            have an adverse effect on the entities whose securities are held
            by the Funds or on domestic or global equity markets or economies,
            generally. Accordingly, PIMCO reserves the right to vary, during
            the first quarter of 2000, the investments of any Fund to maintain
            sufficient liquidity to satisfy actual or anticipated redemption
            activity.

Temporary   For temporary or defensive purposes, each Fund may invest without
Defensive   limit in U.S. debt securities, including taxable securities and
Strategies  short-term money market securities, when PIMCO deems it
            appropriate to do so. When a Fund engages in such strategies, it
            may not achieve its investment objective.

Changes in  The investment objective of each Fund is fundamental and may not
Investment  be changed without shareholder approval. Unless otherwise stated,
Objectives  all other investment policies of the Funds may be changed by the
and         Board of Trustees without shareholder approval.

            Appendix A
            Description of Securities Ratings

            A Fund's investments may range in quality from securities rated in
            the lowest category in which the Fund is permitted to invest to
            securities rated in the highest category (as rated by Moody's or
            S&P or, if unrated, determined by PIMCO to be of comparable
            quality). The percentage of a Fund's assets invested in securities
            in a particular rating category will vary. The following terms are
            generally used to describe the credit quality of fixed income
            securities:

              High Quality Debt Securities are those rated, in one of the two
            highest rating categories (the highest category for commercial
            paper) or, if unrated, deemed comparable by PIMCO.

              Investment Grade Debt Securities are those rated in one of the
            four highest rating categories or, if unrated, deemed comparable
            by PIMCO.

              Below Investment Grade, High Yield Securities ("Junk Bonds") are
            those rated lower than Baa by Moody's or BBB by S&P and comparable
            securities. They are deemed to be predominately speculative with
            respect to the issuer's ability to repay principal and interest.

              Following is a description of Moody's and S&P's rating categories
            applicable to fixed income securities.

Moody's     Corporate and Municipal Bond Ratings
Investors
Service,      Aaa: Bonds which are rated Aaa are judged to be of the best
Inc.        quality. They carry the smallest degree of investment risk and are
            generally referred to as "gilt edge." Interest payments are
            protected by a large or by an exceptionally stable margin and
            principal is secure. While the various protective elements are
            likely to change, such changes as can be visualized are most
            unlikely to impair the fundamentally strong position of such
            issues.

              Aa: Bonds which are rated Aa are judged to be of high quality by
            all standards. Together with the Aaa group they comprise what are
            generally known as high-grade bonds. They are rated lower than the
            best bonds because margins of protection may not be as large as in
            Aaa securities or fluctuation of protective elements may be of
            greater amplitude or there may be other elements present that make
            the long-term risks appear somewhat larger than with Aaa
            securities.

              A: Bonds which are rated A possess many favorable investment
            attributes and are to be considered as upper-medium-grade
            obligations. Factors giving security to principal and interest are
            considered adequate but elements may be present that suggest a
            susceptibility to impairment sometime in the future.

              Baa: Bonds which are rated Baa are considered as medium-grade
            obligations (i.e., they are neither highly protected nor poorly
            secured). Interest payments and principal security appear adequate
            for the present but certain protective elements may be lacking or
            may be characteristically unreliable over any great length of
            time. Such bonds lack outstanding investment characteristics and
            in fact have speculative characteristics as well.

              Ba: Bonds which are rated Ba are judged to have speculative
            elements; their future cannot be considered as well-assured. Often
            the protection of interest and principal payments may be very
            moderate and thereby not well safeguarded during both good and bad
            times over the future. Uncertainty of position characterizes bonds
            in this class.

              B: Bonds which are rated B generally lack characteristics of a
            desirable investment. Assurance of interest and principal payments
            or of maintenance of other terms of the contract over any long
            period of time may be small.

              Caa: Bonds which are rated Caa are of poor standing. Such issues
            may be in default or there may be present elements of danger with
            respect to principal or interest.

              Ca: Bonds which are rated Ca represent obligations which are
            speculative in a high degree. Such issues are often in default or
            have other marked shortcomings.

              C: Bonds which are rated C are the lowest rated class of bonds
            and issues so rated can be regarded as having extremely poor
            prospects of ever attaining any real investment standing.

              Moody's applies numerical modifiers, 1, 2, and 3 in each generic
            rating classified from Aa through B in its corporate bond rating
            system. The modifier 1 indicates that the security ranks in the
            higher end of its generic rating category; the modifier 2
            indicates a mid-range ranking; and the modifier 3 indicates that
            the issue ranks in the lower end of its generic rating category.

                                                                 Prospectus  A-1

            Corporate Short-Term Debt Ratings

              Moody's short-term debt ratings are opinions of the ability of
            issuers to repay punctually senior debt obligations which have an
            original maturity not exceeding one year. Obligations relying upon
            support mechanisms such as letters of credit and bonds of
            indemnity are excluded unless explicitly rated.

              Moody's employs the following three designations, all judged to
            be investment grade, to indicate the relative repayment ability of
            rated issuers:

              PRIME-1: Issuers rated Prime-1 (or supporting institutions) have
            a superior ability for repayment of senior short-term debt
            obligations. Prime-1 repayment ability will often be evidenced by
            many of the following characteristics: leading market positions in
            well-established industries; high rates of return on funds
            employed; conservative capitalization structure with moderate
            reliance on debt and ample asset protection; broad margins in
            earnings coverage of fixed financial charges and high internal
            cash generation; and well-established access to a range of
            financial markets and assured sources of alternate liquidity.

              PRIME-2: Issuers rated Prime-2 (or supporting institutions) have
            a strong ability for repayment of senior short-term debt
            obligations. This will normally be evidenced by many of the
            characteristics cited above but to a lesser degree. Earnings
            trends and coverage ratios, while sound, may be more subject to
            variation. Capitalization characteristics, while still
            appropriate, may be more affected by external conditions. Ample
            alternate liquidity is maintained.

              PRIME-3: Issuers rated Prime-3 (or supporting institutions) have
            an acceptable ability for repayment of senior short-term
            obligations. The effect of industry characteristics and market
            compositions may be more pronounced. Variability in earnings and
            profitability may result in changes in the level of debt
            protection measurements and may require relatively high financial
            leverage. Adequate alternate liquidity is maintained.

              NOT PRIME: Issuers rated Not Prime do not fall within any of the
            Prime rating categories.

            Short-Term Municipal Bond Ratings

              There are four rating categories for short-term municipal bonds
            that define an investment grade situation, which are listed below.
            In the case of variable rate demand obligations (VRDOs), a two-
            component rating is assigned. The first element represents an
            evaluation of the degree of risk associated with scheduled
            principal and interest payments, and the other represents an
            evaluation of the degree of risk associated with the demand
            feature. The short-term rating assigned to the demand feature of
            VRDOs is designated as VMIG. When either the long- or short-term
            aspect of a VRDO is not rated, that piece is designated NR, e.g.,
            Aaa/NR or NR/VMIG 1. MIG ratings terminate at the retirement of
            the obligation while VMIG rating expiration will be a function of
            each issue's specific structural or credit features.

              MIG 1/VMIG 1: This designation denotes best quality. There is
            present strong protection by established cash flows, superior
            liquidity support or demonstrated broad-based access to the market
            for refinancing.

              MIG 2/VMIG 2: This designation denotes high quality. Margins of
            protection are ample although not so large as in the preceding
            group.

              MIG 3/VMIG 3: This designation denotes favorable quality. All
            security elements are accounted for but there is lacking the
            undeniable strength of the preceding grades. Liquidity and cash
            flow protection may be narrow and market access for refinancing is
            likely to be less well established.

              MIG 4/VMIG 4: This designation denotes adequate quality.
            Protection commonly regarded as required of an investment security
            is present and although not distinctly or predominantly
            speculative, there is specific risk.

              SG: This designation denotes speculative quality. Debt
            instruments in this category lack margins of protection.

Standard    Corporate and Municipal Bond Ratings
& Poor's
Ratings     Investment Grade
Services      AAA: Debt rated AAA has the highest rating assigned by S&P.
            Capacity to pay interest and repay principal is extremely strong.

              AA: Debt rated AA has a very strong capacity to pay interest and
            repay principal and differs from the highest rated issues only in
            small degree.

A-2  PIMCO Funds: Pacific Investment Management Series
<PAGE>

              A: Debt rated A has a strong capacity to pay interest and repay
            principal although it is somewhat more susceptible to the adverse
            effects of changes in circumstances and economic conditions than
            debt in higher rated categories.

              BBB: Debt rated BBB is regarded as having an adequate capacity to
            pay interest and repay principal. Whereas it normally exhibits
            adequate protection parameters, adverse economic conditions, or
            changing circumstances are more likely to lead to a weakened
            capacity to pay interest and repay principal for debt in this
            category than in higher-rated categories.

            Speculative Grade
              Debt rated BB, B, CCC, CC, and C is regarded as having
            predominantly speculative characteristics with respect to capacity
            to pay interest and repay principal. BB indicates the least degree
            of speculation and C the highest. While such debt will likely have
            some quality and protective characteristics, these are outweighed
            by large uncertainties or major exposures to adverse conditions.

              BB: Debt rated BB has less near-term vulnerability to default
            than other speculative issues. However, it faces major ongoing
            uncertainties or exposure to adverse business, financial, or
            economic conditions which could lead to inadequate capacity to
            meet timely interest and principal payments. The BB rating
            category is also used for debt subordinated to senior debt that is
            assigned an actual or implied BBB- rating.

              B: Debt rated B has a greater vulnerability to default but
            currently has the capacity to meet interest payments and principal
            repayments. Adverse business, financial, or economic conditions
            will likely impair capacity or willingness to pay interest and
            repay principal. The B rating category is also used for debt
            subordinated to senior debt that is assigned an actual or implied
            BB or BB-rating.

              CCC: Debt rated CCC has a currently identifiable vulnerability to
            default and is dependent upon favorable business, financial, and
            economic conditions to meet timely payment of interest and
            repayment of principal. In the event of adverse business,
            financial or economic conditions, it is not likely to have the
            capacity to pay interest and repay principal. The CCC rating
            category is also used for debt subordinated to senior debt that is
            assigned an actual or implied B or B- rating.

              CC: The rating CC is typically applied to debt subordinated to
            senior debt that is assigned an actual or implied CCC rating.

              C: The rating C is typically applied to debt subordinated to
            senior debt that is assigned an actual or implied CCC- debt
            rating. The C rating may be used to cover a situation where a
            bankruptcy petition has been filed, but debt service payments are
            continued.

              CI: The rating CI is reserved for income bonds on which no
            interest is being paid.

              D: Debt rated D is in payment default. The D rating category is
            used when interest payments or principal payments are not made on
            the date due even if the applicable grace period has not expired,
            unless S&P believes that such payments will be made during such
            grace period. The D rating will also be used upon the filing of a
            bankruptcy petition if debt service payments are jeopardized.

              Plus (+) or Minus (-): The ratings from AA to CCC may be modified
            by the addition of a plus or minus sign to show relative standing
            within the major rating categories.

              Provisional ratings: The letter "p" indicates that the rating is
            provisional. A provisional rating assumes the successful
            completion of the project being financed by the debt being rated
            and indicates that payment of debt service requirements is largely
            or entirely dependent upon the successful and timely completion of
            the project. This rating, however, while addressing credit quality
            subsequent to completion of the project, makes no comment on the
            likelihood of, or the risk of default upon failure of, such
            completion. The investor should exercise his own judgment with
            respect to such likelihood and risk.

              r: The "r" is attached to highlight derivative, hybrid, and
            certain other obligations that S&P believes may experience high
            volatility or high variability in expected returns due to non-
            credit risks. Examples of such obligations are: securities whose
            principal or interest return is indexed to equities, commodities,
            or currencies; certain swaps and options; and interest only and
            principal only mortgage securities.

              The absence of an "r" symbol should not be taken as an indication
            that an obligation will exhibit no volatility or variability in
            total return.

              N.R.: Not rated.

              Debt obligations of issuers outside the United States and its
            territories are rated on the same basis as domestic corporate and
            municipal issues. The ratings measure the creditworthiness of the
            obligor but do not take into account currency exchange and related
            uncertainties.

                                                              Prospectus  A-3
<PAGE>

Commercial  An S&P commercial paper rating is a current assessment of the
Paper       likelihood of timely payment of debt having an original maturity
Rating      of no more than 365 days. Ratings are graded into several
Definitions categories, ranging from A for the highest quality obligations to
            D for the lowest. These categories are as follows:

              A-1: This highest category indicates that the degree of safety
            regarding timely payment is strong. Those issues determined to
            possess extremely strong safety characteristics are denoted with a
            plus sign (+) designation.

              A-2: Capacity for timely payment on issues with this designation
            is satisfactory. However, the relative degree of safety is not as
            high as for issues designated A-1.

              A-3: Issues carrying this designation have adequate capacity for
            timely payment. They are, however, more vulnerable to the adverse
            effects of changes in circumstances than obligations carrying the
            higher designations.

              B: Issues rated B are regarded as having only speculative capacity
            for timely payment.

              C: This rating is assigned to short-term debt obligations with a
            doubtful capacity for payment.

              D: Debt rated D is in payment default. The D rating category is
            used when interest payments or principal payments are not made on
            the date due, even if the applicable grace period has not expired,
            unless S&P believes that such payments will be made during such
            grace period.

              A commercial paper rating is not a recommendation to purchase,
            sell or hold a security inasmuch as it does not comment as to
            market price or suitability for a particular investor. The ratings
            are based on current information furnished to S&P by the issuer or
            obtained from other sources it considers reliable. S&P does not
            perform an audit in connection with any rating and may, on
            occasion, rely on unaudited financial information. The ratings may
            be changed, suspended, or withdrawn as a result of changes in or
            unavailability of such information.

("mutual fund") currently consisting of thirty separate investment portfolios
(the "Funds"): the PIMCO Money Market Fund; the PIMCO Short-Term Fund; the PIMCO
Low Duration Fund; the PIMCO Low Duration Fund II; the PIMCO Low Duration Fund
III; the PIMCO Low Duration Mortgage Fund; the PIMCO Moderate Duration Fund; the
PIMCO Real Return Bond Fund; the PIMCO Total Return Fund; the PIMCO Total Return
Fund II; the PIMCO Total Return Fund III; the PIMCO Total Return Mortgage Fund;
the PIMCO Commercial Mortgage Securities Fund; the PIMCO High Yield Fund; the
PIMCO Long-Term U.S. Government Fund; the PIMCO Long Duration Fund; the PIMCO
Global Bond Fund; the PIMCO Global Bond Fund II; the PIMCO Foreign Bond Fund;

Fund; and the PIMCO StocksPLUS Short Strategy Fund. Shares of the PIMCO
International Bond Fund and PIMCO Emerging Markets Bond Fund II are offered only
to clients of PIMCO who maintain separately managed private accounts.

                       INVESTMENT OBJECTIVES AND POLICIES

     The investment objectives and general investment policies of each Fund are
described in the Prospectuses. Additional information concerning the
characteristics of certain of the Funds' investments is set forth below.

Borrowing

     A Fund may borrow for temporary administrative purposes. This borrowing may
be unsecured. Provisions of the Investment Company Act of 1940 ("1940 Act")
require a Fund to maintain continuous asset coverage (that is, total assets
including borrowings, less liabilities exclusive of borrowings) of 300% of the
amount borrowed, with an exception for borrowings not in excess of 5% of the
Fund's total assets made for temporary administrative purposes. Any borrowings
for temporary administrative purposes in excess of 5% of the Fund's total assets
must maintain continuous asset coverage. If the 300% asset coverage should
decline as a result of market fluctuations or other reasons, a Fund may be
required to sell some of its portfolio holdings within three days to reduce the
debt and restore the 300% asset coverage, even though it may be disadvantageous
from an investment standpoint to sell securities at that time. As noted below, a
Fund also may enter into certain transactions, including reverse repurchase
agreements, mortgage dollar rolls, and sale-buybacks, that can be viewed as
constituting a form of borrowing or financing transaction by the Fund. To the
extent a Fund covers its commitment under a reverse repurchase agreement (or
economically similar transaction) by the segregation of assets determined in
accordance with procedures adopted by the Trustees, equal in value to the amount
of the Fund's commitment to repurchase, such an agreement will not be considered
a "senior security" by the Fund and therefore will not be subject to the 300%
asset coverage requirement otherwise applicable to borrowings by the Funds.
Borrowing will tend to exaggerate the effect on net asset value of any increase
or decrease in the market value of a Fund's portfolio. Money borrowed will be
subject to interest costs which may or may not be recovered by appreciation of
the securities purchased. A Fund also may be required to maintain minimum
average balances in connection with such borrowing or to pay a commitment or
other fee to maintain a line of credit; either of these requirements would
increase the cost of borrowing over the stated interest rate. The PIMCO Global
Bond Fund II may not borrow in excess of
<PAGE>

10% of the value of its total assets and then only from banks as a temporary
measure to facilitate the meeting of redemption requests (not for leverage)
or for extraordinary or emergency purposes.

     In addition to borrowing for temporary purposes, a Fund may enter into
reverse repurchase agreements, mortgage dollar rolls, and economically similar
transactions. A reverse repurchase agreement involves the sale of a portfolio-
eligible security by a Fund, coupled with its agreement to repurchase the
instrument at a specified time and price. Under a reverse repurchase agreement,
the Fund continues to receive any principal and interest payments on the
underlying security during the term of the agreement. The Fund typically will
segregate assets determined to be liquid by the Adviser in accordance with
procedures established by the Board of Trustees, equal (on a daily
mark-to-market basis) to its obligations under reverse repurchase agreements.
However, reverse repurchase agreements involve the risk that the market value of
securities retained by the Fund may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase. To the extent
that positions in reverse repurchase agreements are not covered through the
segregation of liquid assets at least equal to the amount of any forward
purchase commitment, such transactions would be subject to the Funds'
limitations on borrowings, which would restrict the aggregate of such
transactions (plus any other borrowings) to 33 1/3% (for each Fund except the
PIMCO Global Bond Fund II) of a Fund's total assets.

     A "mortgage dollar roll" is similar to a reverse repurchase agreement in
certain respects. In a "dollar roll" transaction a Fund sells a mortgage-related
security, such as a security issued by the Government National Mortgage
Association ("GNMA"), to a dealer and simultaneously agrees to repurchase a
similar security (but not the same security) in the future at a pre-determined
price. A "dollar roll" can be viewed, like a reverse repurchase agreement, as a
collateralized borrowing in which a Fund pledges a mortgage-related security to
a dealer to obtain cash. Unlike in the case of reverse repurchase agreements,
the dealer with which a Fund enters into a dollar roll transaction is not
obligated to return the same securities as those originally sold by the Fund,
but only securities which are "substantially identical." To be considered
"substantially identical," the securities returned to a Fund generally must: (1)
be collateralized by the same types of underlying mortgages; (2) be issued by
the same agency and be part of the same program; (3) have a similar original
stated maturity; (4) have identical net coupon rates; (5) have similar market
yields (and therefore price); and (6) satisfy "good delivery" requirements,
meaning that the aggregate principal amounts of the securities delivered and
received back must be within 2.5% of the initial amount delivered.

     A Fund's obligations under a dollar roll agreement must be covered by
segregated liquid assets equal in value to the securities subject to repurchase
by the Fund. As with reverse repurchase agreements, to the extent that positions
in dollar roll agreements are not covered by segregated liquid assets at least
equal to the amount of any forward purchase commitment, such transactions would
be subject to the Funds' limitations on borrowings. Furthermore, because dollar
roll transactions may be for terms ranging between one and six months, dollar
roll transactions may be deemed "illiquid" and subject to a Fund's overall
limitations on investments in illiquid securities. A Fund also may effect
simultaneous purchase and sale transactions that are known as "sale-buybacks". A
sale-buyback is similar to a reverse repurchase agreement, except that in a
sale-buyback, the counterparty who purchases the security is entitled to receive
any principal or interest payments make on the underlying security pending
settlement of the Fund's repurchase of the underlying security. A Fund's
obligations under a sale-buyback typically would be offset by liquid assets
equal in value to the amount of the Fund's forward commitment to repurchase the
subject security.

Corporate Debt Securities

     A Fund's investments in U.S. dollar or foreign currency-denominated
corporate debt securities of domestic or foreign issuers are limited to
corporate debt securities (corporate bonds, debentures, notes and other similar
corporate debt instruments, including convertible securities) which meet the
minimum

                                       2

<PAGE>

ratings criteria set forth for the Fund, or, if unrated, are in the Adviser's
opinion comparable in quality to corporate debt securities in which the Fund
may invest.

     Corporate income-producing securities may include forms of preferred or
preference stock. The rate of interest on a corporate debt security may be
fixed, floating or variable, and may vary inversely with respect to a reference
rate. The rate of return or return of principal on some debt obligations may be
linked or indexed to the level of exchange rates between the U.S. dollar and a
foreign currency or currencies. Debt securities may be acquired with warrants
attached.

     Securities rated Baa and BBB are the lowest which are considered
"investment grade" obligations. Moody's Investor Service, Inc. ("Moody's")
describes securities rated Baa as "medium-grade" obligations; they are "neither
highly protected nor poorly secured . . . [i]nterest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well." Standard & Poor's Ratings Services ("S&P")
describes securities rated BBB as "regarded as having an adequate capacity to
pay interest and repay principal . . . [w]hereas it normally exhibits adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal
 . . . than in higher rated categories." For a discussion of securities rated
below investment grade, see "High Yield Securities ("Junk Bonds")" below.

Convertible Securities

     A convertible debt security is a bond, debenture, note, or other security
that entitles the holder to acquire common stock or other equity securities of
the same or a different issuer. A convertible security generally entitles the
holder to receive interest paid or accrued until the convertible security
matures or is redeemed, converted or exchanged. Before conversion, convertible
securities have characteristics similar to non-convertible debt securities.
Convertible securities rank senior to common stock in a corporation's capital
structure and, therefore, generally entail less risk than the corporation's
common stock, although the extent to which such risk is reduced depends in large
measure upon the degree to which the convertible security sells above its value
as a fixed income security.

     Because of the conversion feature, the price of the convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying asset, and as such is subject to risks relating to the activities of
the issuer and/or general market and economic conditions. The income component
of a convertible security may tend to cushion the security against declines in
the price of the underlying asset. However, the income component of convertible
securities causes fluctuations based upon changes in interest rates and the
credit quality of the issuer. In addition, convertible securities are often
lower-rated securities.

     A convertible security may be subject to redemption at the option of the
issuer at a predetermined price. If a convertible security held by a Fund is
called for redemption, the Fund would be required to permit the issuer to redeem
the security and convert it to underlying common stock, or would sell the
convertible security to a third party, which may have an adverse effect on the
Fund's ability to achieve its investment objective. A Fund generally would
invest in convertible securities for their favorable price characteristics and
total return potential and would normally not exercise an option to convert.

High Yield Securities ("Junk Bonds")

     Investments in securities rated below investment grade that are eligible
for purchase by certain of the Funds (i.e., rated B or better by Moody's or
S&P), and in particular, by the PIMCO High Yield Fund, are described as
"speculative" by both Moody's and S&P. Investment in lower rated corporate debt
securities ("high yield securities" or "junk bonds") generally provides greater
income and increased


                                       3
<PAGE>

opportunity for capital appreciation than investments in higher quality
securities, but they also typically entail greater price volatility and
principal and income risk. These high yield securities are regarded as
predominantly speculative with respect to the issuer's continuing ability to
meet principal and interest payments. Analysis of the creditworthiness of
issuers of debt securities that are high yield may be more complex than for
issuers of higher quality debt securities.

     High yield securities may be more susceptible to real or perceived adverse
economic and competitive industry conditions than investment grade securities.
The prices of high yield securities have been found to be less sensitive to
interest-rate changes than higher-rated investments, but more sensitive to
adverse economic downturns or individual corporate developments. A projection of
an economic downturn or of a period of rising interest rates, for example, could
cause a decline in high yield security prices because the advent of a recession
could lessen the ability of a highly leveraged company to make principal and
interest payments on its debt securities. If an issuer of high yield securities
defaults, in addition to risking payment of all or a portion of interest and
principal, the Funds investing in such securities may incur additional expenses
to seek recovery. In the case of high yield securities structured as zero-coupon
or pay-in-kind securities, their market prices are affected to a greater extent
by interest rate changes, and therefore tend to be more volatile than securities
which pay interest periodically and in cash. The Adviser seeks to reduce these
risks through diversification, credit analysis and attention to current
developments and trends in both the economy and financial markets.

     The secondary market on which high yield securities are traded may be less
liquid than the market for higher grade securities. Less liquidity in the
secondary trading market could adversely affect the price at which the Funds
could sell a high yield security, and could adversely affect the daily net asset
value of the shares. Adverse publicity and investor perceptions, whether or not
based on fundamental analysis, may decrease the values and liquidity of high
yield securities, especially in a thinly-traded market. When secondary markets
for high yield securities are less liquid than the market for higher grade
securities, it may be more difficult to value the securities because such
valuation may require more research, and elements of judgment may play a greater
role in the valuation because there is less reliable, objective data available.
The Adviser seeks to minimize the risks of investing in all securities through
diversification, in-depth credit analysis and attention to current developments
in interest rates and market conditions.

     The use of credit ratings as the sole method of evaluating high yield
securities can involve certain risks. For example, credit ratings evaluate the
safety of principal and interest payments, not the market value risk of high
yield securities. Also, credit rating agencies may fail to change credit ratings
in a timely fashion to reflect events since the security was last rated. The
Adviser does not rely solely on credit ratings when selecting securities for the
Funds, and develops its own independent analysis of issuer credit quality. If a
credit rating agency changes the rating of a portfolio security held by a Fund,
the Fund may retain the portfolio security if the Adviser deems it in the best
interest of shareholders.

Variable and Floating Rate Securities

     Variable and floating rate securities provide for a periodic adjustment in
the interest rate paid on the obligations. The terms of such obligations must
provide that interest rates are adjusted periodically based upon an interest
rate adjustment index as provided in the respective obligations. The adjustment
intervals may be regular, and range from daily up to annually, or may be event
based, such as based on a change in the prime rate. The Money Market Fund may
invest in a variable rate security having a stated maturity in excess of 397
calendar days if the interest rate will be adjusted, and the Fund may demand
payment of principal from the issuers, within the period.

     Each Fund may invest in floating rate debt instruments ("floaters") and
(except the Money Market and Municipal Bond Funds) engage in credit spread
trades. The interest rate on a floater is a variable rate which is tied to
another interest rate, such as a money-market index or Treasury bill rate. The
interest rate on a floater resets periodically, typically every six months.
While, because of the


                                       4
<PAGE>

interest rate reset feature, floaters provide a Fund with a certain degree of
protection against rises in interest rates, a Fund will participate in any
declines in interest rates as well. A credit spread trade is an investment
position relating to a difference in the prices or interest rates of two
securities or currencies, where the value of the investment position is
determined by movements in the difference between the prices or interest rates,
as the case may be, of the respective securities or currencies.

     Each Fund (except the PIMCO Money Market and Municipal Bond Funds) may also
invest in inverse floating rate debt instruments ("inverse floaters"). The
interest rate on an inverse floater resets in the opposite direction from the
market rate of interest to which the inverse floater is indexed. An inverse
floating rate security may exhibit greater price volatility than a fixed rate
obligation of similar credit quality. The Funds have adopted a policy under
which no Fund will invest more than 5% of its net assets in any combination of
inverse floater, interest only ("IO"), or principal only ("PO") securities.

Participation on Creditors Committees

     A Fund (in particular, the PIMCO High Yield Fund) may from time to time
participate on committees formed by creditors to negotiate with the management
of financially troubled issuers of securities held by the Fund. Such
participation may subject a Fund to expenses such as legal fees and may make a
Fund an "insider" of the issuer for purposes of the federal securities laws, and
therefore may restrict such Fund's ability to trade in or acquire additional
positions in a particular security when it might otherwise desire to do so.
Participation by a Fund on such committees also may expose the Fund to potential
liabilities under the federal bankruptcy laws or other laws governing the rights
of creditors and debtors. A Fund will participate on such committees only when
the Adviser believes that such participation is necessary or desirable to
enforce the Fund's rights as a creditor or to protect the value of securities
held by the Fund.

Mortgage-Related and Other Asset-Backed Securities

     Mortgage-related securities are interests in pools of residential or
commercial mortgage loans, including mortgage loans made by savings and loan
institutions, mortgage bankers, commercial banks and others. Pools of mortgage
loans are assembled as securities for sale to investors by various governmental,
government-related and private organizations. See "Mortgage Pass-Through
Securities." Certain of the Funds may also invest in debt securities which are
secured with collateral consisting of mortgage-related securities (see
"Collateralized Mortgage Obligations"), and in other types of mortgage-related
securities.

     Mortgage Pass-Through Securities. Interests in pools of mortgage-related
securities differ from other forms of debt securities, which normally provide
for periodic payment of interest in fixed amounts with principal payments at
maturity or specified call dates. Instead, these securities provide a monthly
payment which consists of both interest and principal payments. In effect, these
payments are a "pass-through" of the monthly payments made by the individual
borrowers on their residential or commercial mortgage loans, net of any fees
paid to the issuer or guarantor of such securities. Additional payments are
caused by repayments of principal resulting from the sale of the underlying
property, refinancing or foreclosure, net of fees or costs which may be
incurred. Some mortgage-related securities (such as securities issued by GNMA)
are described as "modified pass-through." These securities entitle the holder to
receive all interest and principal payments owed on the mortgage pool, net of
certain fees, at the scheduled payment dates regardless of whether or not the
mortgagor actually makes the payment.

     The rate of prepayments on underlying mortgages will affect the price and
volatility of a mortgage-related security, and may have the effect of shortening
or extending the effective maturity of the security beyond what was anticipated
at the time of purchase. To the extent that unanticipated rates of prepayment on
underlying mortgages increase in the effective maturity of a mortgage-related
security, the volatility of such security can be expected to increase.


                                       5
<PAGE>

     The principal governmental guarantor of mortgage-related securities is
GNMA. GNMA is a wholly owned United States Government corporation within the
Department of Housing and Urban Development. GNMA is authorized to guarantee,
with the full faith and credit of the United States Government, the timely
payment of principal and interest on securities issued by institutions approved
by GNMA (such as savings and loan institutions, commercial banks and mortgage
bankers) and backed by pools of mortgages insured by the Federal Housing
Administration (the "FHA"), or guaranteed by the Department of Veterans Affairs
(the "VA").

     Government-related guarantors (i.e., not backed by the full faith and
credit of the United States Government) include the Federal National Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC").
FNMA is a government-sponsored corporation owned entirely by private
stockholders. It is subject to general regulation by the Secretary of Housing
and Urban Development. FNMA purchases conventional (i.e., not insured or
guaranteed by any government agency) residential mortgages from a list of
approved seller/servicers which include state and federally chartered savings
and loan associations, mutual savings banks, commercial banks and credit unions
and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as
to timely payment of principal and interest by FNMA but are not backed by the
full faith and credit of the United States Government. FHLMC was created by
Congress in 1970 for the purpose of increasing the availability of mortgage
credit for residential housing. It is a government-sponsored corporation
formerly owned by the twelve Federal Home Loan Banks and now owned entirely by
private stockholders. FHLMC issues Participation Certificates ("PCs") which
represent interests in conventional mortgages from FHLMC's national portfolio.
FHLMC guarantees the timely payment of interest and ultimate collection of
principal, but PCs are not backed by the full faith and credit of the United
States Government.

     Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through pools of conventional residential mortgage loans. Such issuers may,
in addition, be the originators and/or servicers of the underlying mortgage
loans as well as the guarantors of the mortgage-related securities. Pools
created by such non-governmental issuers generally offer a higher rate of
interest than government and government-related pools because there are no
direct or indirect government or agency guarantees of payments in the former
pools. However, timely payment of interest and principal of these pools may be
supported by various forms of insurance or guarantees, including individual
loan, title, pool and hazard insurance and letters of credit, which may be
issued by governmental entities, private insurers or the mortgage poolers. The
insurance and guarantees are issued by governmental entities, private insurers
and the mortgage poolers. Such insurance and guarantees and the creditworthiness
of the issuers thereof will be considered in determining whether a
mortgage-related security meets the Trust's investment quality standards. There
can be no assurance that the private insurers or guarantors can meet their
obligations under the insurance policies or guarantee arrangements. The Funds
may buy mortgage-related securities without insurance or guarantees if, through
an examination of the loan experience and practices of the originator/servicers
and poolers, the Adviser determines that the securities meet the Trust's quality
standards. Although the market for such securities is becoming increasingly
liquid, securities issued by certain private organizations may not be readily
marketable. No Fund will purchase mortgage-related securities or any other
assets which in the Adviser's opinion are illiquid if, as a result, more than
15% of the value of the Fund's net assets will be illiquid (10% in the case of
the PIMCO Money Market Fund.)

     Mortgage-backed securities that are issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, are not subject to the Funds'
industry concentration restrictions, set forth below under "Investment
Restrictions," by virtue of the exclusion from that test available to all U.S.
Government securities. In the case of privately issued mortgage-related
securities, the Funds take the position that mortgage-related securities do not
represent interests in any particular "industry" or group of industries. The
assets underlying such securities may be represented by a portfolio of first
lien residential mortgages (including both whole mortgage loans and mortgage
participation interests) or portfolios of mortgage pass-through securities
issued or guaranteed by GNMA, FNMA or FHLMC. Mortgage loans underlying a
mortgage-related security may in turn be insured or guaranteed by the FHA or the
VA. In the case of

                                       6
<PAGE>

private issue mortgage-related securities whose underlying assets are neither
U.S. Government securities nor U.S. Government-insured mortgages, to the extent
that real properties securing such assets may be located in the same
geographical region, the security may be subject to a greater risk of default
than other comparable securities in the event of adverse economic, political or
business developments that may affect such region and, ultimately, the ability
of residential homeowners to make payments of principal and interest on the
underlying mortgages.

     Collateralized Mortgage Obligations (CMOs). A CMO is a hybrid between a
mortgage-backed bond and a mortgage pass-through security. Similar to a bond,
interest and prepaid principal is paid, in most cases, on a monthly basis. CMOs
may be collateralized by whole mortgage loans, but are more typically
collateralized by portfolios of mortgage pass-through securities guaranteed by
GNMA, FHLMC, or FNMA, and their income streams.

     CMOs are structured into multiple classes, each bearing a different stated
maturity. Actual maturity and average life will depend upon the prepayment
experience of the collateral. CMOs provide for a modified form of call
protection through a de facto breakdown of the underlying pool of mortgages
according to how quickly the loans are repaid. Monthly payment of principal
received from the pool of underlying mortgages, including prepayments, is first
returned to investors holding the shortest maturity class. Investors holding the
longer maturity classes receive principal only after the first class has been
retired. An investor is partially guarded against a sooner than desired return
of principal because of the sequential payments.

     In a typical CMO transaction, a corporation ("issuer") issues multiple
series (e.g., A, B, C, Z) of CMO bonds ("Bonds"). Proceeds of the Bond offering
are used to purchase mortgages or mortgage pass-through certificates
("Collateral"). The Collateral is pledged to a third party trustee as security
for the Bonds. Principal and interest payments from the Collateral are used to
pay principal on the Bonds in the order A, B, C, Z. The Series A, B, and C Bonds
all bear current interest. Interest on the Series Z Bond is accrued and added to
principal and a like amount is paid as principal on the Series A, B, or C Bond
currently being paid off. When the Series A, B, and C Bonds are paid in full,
interest and principal on the Series Z Bond begins to be paid currently. With
some CMOs, the issuer serves as a conduit to allow loan originators (primarily
builders or savings and loan associations) to borrow against their loan
portfolios.

     FHLMC Collateralized Mortgage Obligations. FHLMC CMOs are debt obligations
of FHLMC issued in multiple classes having different maturity dates which are
secured by the pledge of a pool of conventional mortgage loans purchased by
FHLMC. Unlike FHLMC PCs, payments of principal and interest on the CMOs are made
semi-annually, as opposed to monthly. The amount of principal payable on each
semiannual payment date is determined in accordance with FHLMC's mandatory
sinking fund schedule, which, in turn, is equal to approximately 100% of FHA
prepayment experience applied to the mortgage collateral pool. All sinking fund
payments in the CMOs are allocated to the retirement of the individual classes
of bonds in the order of their stated maturities. Payment of principal on the
mortgage loans in the collateral pool in excess of the amount of FHLMC's minimum
sinking fund obligation for any payment date are paid to the holders of the CMOs
as additional sinking fund payments. Because of the "pass-through" nature of all
principal payments received on the collateral pool in excess of FHLMC's minimum
sinking fund requirement, the rate at which principal of the CMOs is actually
repaid is likely to be such that each class of bonds will be retired in advance
of its scheduled maturity date.

     If collection of principal (including prepayments) on the mortgage loans
during any semi-annual payment period is not sufficient to meet FHLMC's minimum
sinking fund obligation on the next sinking fund payment date, FHLMC agrees to
make up the deficiency from its general funds.

     Criteria for the mortgage loans in the pool backing the FHLMC CMOs are
identical to those of FHLMC PCs. FHLMC has the right to substitute collateral in
the event of delinquencies and/or defaults.

     Commercial Mortgage-Backed Securities include securities that reflect an
interest in, and are secured by, mortgage loans on commercial real property. The
market for commercial mortgage-backed securities developed more recently and in
terms of total outstanding principal amount of issues is relatively small
compared to the market for residential single-family mortgage-backed securities.
Many of the risks of investing in commercial mortgage-backed securities reflect
the risks of investing in the real estate securing the underlying mortgage
loans. These risks reflect the effects of local and other economic conditions on
real estate markets, the ability of tenants to make loan payments, and the
ability of a property to attract and retain tenants. Commercial mortgage-backed
securities may be less liquid and exhibit greater price volatility than other
types of mortgage- or asset-backed securities.

     Other Mortgage-Related Securities. Other mortgage-related securities
include securities other than those described above that directly or indirectly
represent a participation in, or are secured by and payable from, mortgage loans
on real property, including mortgage dollar rolls, CMO residuals or stripped
mortgage-backed securities ("SMBS"). Other mortgage-related securities may be
equity or debt securities issued by agencies or instrumentalities of the U.S.
Government or by private originators of, or investors in, mortgage loans,
including savings and loan associations, homebuilders, mortgage banks,
commercial banks, investment banks, partnerships, trusts and special purpose
entities of the foregoing.

     CMO Residuals. CMO residuals are mortgage securities issued by agencies or
instrumentalities of the U.S. Government or by private originators of, or
investors in, mortgage loans, including savings and loan associations,
homebuilders, mortgage banks, commercial banks, investment banks and special
purpose entities of the foregoing.

     The cash flow generated by the mortgage assets underlying a series of CMOs
is applied first to make required payments of principal and interest on the CMOs
and second to pay the related administrative expenses of the issuer. The
residual in a CMO structure generally represents the interest in any excess cash
flow remaining after making the foregoing payments. Each payment of such excess
cash flow to a holder of the related CMO residual represents income and/or a
return of capital. The amount of residual cash flow resulting from a CMO will
depend on, among other things, the characteristics of the mortgage assets, the
coupon rate of each class of CMO, prevailing interest rates, the amount of
administrative expenses and the prepayment experience on the mortgage assets. In
particular, the yield to maturity on CMO residuals is extremely sensitive to
prepayments on the related underlying mortgage assets, in the same manner as an
interest-only ("IO") class of stripped mortgage-backed securities. See "Other
Mortgage-Related Securities--Stripped Mortgage-Backed Securities." In addition,
if a series of a CMO includes a class that bears interest at an adjustable rate,
the yield to maturity on the related CMO residual will also be extremely
sensitive to changes in the level of the index upon which interest rate
adjustments are based. As described below with respect to stripped
mortgage-backed securities, in certain circumstances a Fund may fail to recoup
fully its initial investment in a CMO residual.

     CMO residuals are generally purchased and sold by institutional investors
through several investment banking firms acting as brokers or dealers. The CMO
residual market has only very recently developed and CMO residuals currently may
not have the liquidity of other more established securities trading in other
markets. Transactions in CMO residuals are generally completed only after
careful review of the characteristics of the securities in question. In
addition, CMO residuals may, or pursuant to an exemption therefrom, may not have
been registered under the Securities Act of 1933, as amended (the "1933 Act").
CMO residuals, whether or not registered under the 1933 Act, may be subject to
certain restrictions on transferability, and may be deemed "illiquid" and
subject to a Fund's limitations on investment in illiquid securities.

     Stripped Mortgage-Backed Securities. SMBS are derivative multi-class
mortgage securities. SMBS may be issued by agencies or instrumentalities of the
U.S. Government, or by private originators of, or investors in, mortgage loans,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose entities of the foregoing.

                                       8
<PAGE>

     SMBS are usually structured with two classes that receive different
proportions of the interest and principal distributions on a pool of mortgage
assets. A common type of SMBS will have one class receiving some of the interest
and most of the principal from the mortgage assets, while the other class will
receive most of the interest and the remainder of the principal. In the most
extreme case, one class will receive all of the interest (the "IO" class), while
the other class will receive all of the principal (the principal- only or "PO"
class). The yield to maturity on an IO class is extremely sensitive to the rate
of principal payments (including prepayments) on the related underlying mortgage
assets, and a rapid rate of principal payments may have a material adverse
effect on a Fund's yield to maturity from these securities. If the underlying
mortgage assets experience greater than anticipated prepayments of principal, a
Fund may fail to recoup some or all of its initial investment in these
securities even if the security is in one of the highest rating categories.

     Although SMBS are purchased and sold by institutional investors through
several investment banking firms acting as brokers or dealers, these securities
were only recently developed. As a result, established trading markets have not
yet developed and, accordingly, these securities may be deemed "illiquid" and
subject to a Fund's limitations on investment in illiquid securities.

     Other Asset-Backed Securities. Similarly, the Adviser expects that other
asset-backed securities (unrelated to mortgage loans) will be offered to
investors in the future. Several types of asset-backed securities have already
been offered to investors, including Certificates for Automobile ReceivablesSM
("CARSSM"). CARSSM represent undivided fractional interests in a trust whose
assets consist of a pool of motor vehicle retail installment sales contracts and
security interests in the vehicles securing the contracts. Payments of principal
and interest on CARSSM are passed through monthly to certificate holders, and
are guaranteed up to certain amounts and for a certain time period by a letter
of credit issued by a financial institution unaffiliated with the trustee or
originator of the trust. An investor's return on CARSSM may be affected by early
prepayment of principal on the underlying vehicle sales contracts. If the letter
of credit is exhausted, the trust may be prevented from realizing the full
amount due on a sales contract because of state law requirements and
restrictions relating to foreclosure sales of vehicles and the obtaining of
deficiency judgments following such sales or because of depreciation, damage or
loss of a vehicle, the application of federal and state bankruptcy and
insolvency laws, or other factors. As a result, certificate holders may
experience delays in payments or losses if the letter of credit is exhausted.

     Consistent with a Fund's investment objectives and policies, the Adviser
also may invest in other types of asset-backed securities.

Foreign Securities

     All Funds (except the PIMCO Low Duration II, Total Return II, Long-Term
U.S. Government, Short Duration Municipal Income, Municipal Bond, California
Intermediate Municipal Bond and New York Intermediate Municipal Bond Funds) may
invest in corporate debt securities of foreign issuers (including preferred or
preference stock), certain foreign bank obligations (see "Bank Obligations") and
U.S. dollar or foreign currency-denominated obligations of foreign governments
or their subdivisions, agencies and instrumentalities, international agencies
and supranational entities. The PIMCO Money Market, Commercial Mortgage
Securities, Low Duration Mortgage and Total Return Mortgage Funds may invest in
securities of foreign issuers only if they are U.S. dollar-denominated. The
PIMCO High Yield Fund may invest up to 15% of its assets in euro-denominated
securities.

     Securities traded in certain emerging market countries, including the
emerging market countries in Eastern Europe, may be subject to risks in addition
to risks typically posed by international investing due to the inexperience of
financial intermediaries, the lack of modern technology, and the lack of a
sufficient capital base to expand business operations. Additionally, former
Communist regimes of a number of Eastern European countries previously
expropriated a large amount of property, the claims on which have not been
entirely settled. There can be no assurance that a Fund's investments in Eastern
Europe will not also be expropriated, nationalized or otherwise confiscated.

     Each of the Fixed Income Funds (except the PIMCO Low Duration II, Total
Return II, Long-Term U.S. Government, Short Duration Municipal Income, Municipal
Bond, California Intermediate Municipal Bond and New York Intermediate Municipal
Bond Funds) may invest in Brady Bonds. Brady Bonds are securities created
through the exchange of existing commercial bank loans to sovereign entities for
new obligations in connection with debt restructurings under a debt
restructuring plan introduced by former U.S. Secretary of the Treasury, Nicholas
F. Brady (the "Brady Plan"). Brady Plan debt restructurings have been
implemented in a number of countries, including: Argentina, Bolivia, Bulgaria,
Costa Rica, the Dominican Republic, Ecuador, Jordan, Mexico, Niger, Nigeria, the
Philippines, Poland, Uruguay, and Venezuela. In addition, Brazil has concluded a
Brady-like plan. It is expected that other countries will undertake a Brady Plan
in the future, including Panama and Peru.

     Brady Bonds have been issued only recently, and accordingly do not have a
long payment history. Brady Bonds may be collateralized or uncollateralized, are
issued in various currencies (primarily the U.S. dollar) and are actively traded
in the over-the-counter secondary market. Brady Bonds are not considered to be
U.S. Government securities. U.S. dollar-denominated, collateralized Brady Bonds,
which may be fixed rate par bonds or floating rate discount bonds, are generally
collateralized in full as to principal by U.S. Treasury zero coupon bonds having
the same maturity as the Brady Bonds. Interest payments on these Brady Bonds
generally are collateralized on a one-year or longer rolling-forward basis by
cash or securities in an amount that, in the case of fixed rate bonds, is equal
to at least one year of interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's interest payments based on the
applicable interest rate at that time and is adjusted at regular intervals
thereafter. Certain Brady Bonds are entitled to "value recovery payments" in
certain circumstances, which in effect constitute supplemental interest payments
but generally are not collateralized. Brady Bonds are often viewed as having
three or four valuation components: (i) the collateralized repayment of
principal at final maturity; (ii) the collateralized interest payments; (iii)
the uncollateralized interest payments; and (iv) any uncollateralized repayment
of principal at maturity (these uncollateralized amounts constitute the
"residual risk").

     Most Mexican Brady Bonds issued to date have principal repayments at final
maturity fully collateralized by U.S. Treasury zero coupon bonds (or comparable
collateral denominated in other currencies) and interest coupon payments
collateralized on an 18-month rolling-forward basis by funds held in escrow by
an agent for the bondholders. A significant portion of the Venezuelan Brady
Bonds and the Argentine Brady Bonds issued to date have principal repayments at
final maturity collateralized by U.S. Treasury zero coupon bonds (or comparable
collateral denominated in other currencies) and/or interest coupon payments
collateralized on a 14-month (for Venezuela) or 12-month (for Argentina)
rolling-forward basis by securities held by the Federal Reserve Bank of New York
as collateral agent.

     Brady Bonds involve various risk factors including residual risk and the
history of defaults with respect to commercial bank loans by public and private
entities of countries issuing Brady Bonds. There can be no assurance that Brady
Bonds in which the Funds may invest will not be subject to restructuring
arrangements or to requests for new credit, which may cause the Funds to suffer
a loss of interest or principal on any of its holdings.

     Investment in sovereign debt can involve a high degree of risk. The
governmental entity that controls the repayment of sovereign debt may not be
able or willing to repay the principal and/or interest when due in accordance
with the terms of the debt. A governmental entity's willingness or ability to
repay principal and interest due in a timely manner may be affected by, among
other factors, its cash flow situation, the extent of its foreign reserves, the
availability of sufficient foreign exchange on the date a payment is due, the
relative size of the debt service burden to the economy as a whole, the
governmental entity's policy toward the International Monetary Fund, and the
political constraints to which a governmental entity may be subject.
Governmental entities may also depend on expected disbursements from foreign
governments, multilateral agencies and others to reduce principal and interest
arrearages on their debt. The commitment on the part of these governments,
agencies and others to make such disbursements may be conditioned on a
governmental entity's implementation of economic

                                       10
<PAGE>

reforms and/or economic performance and the timely service of such debtor's
obligations. Failure to implement such reforms, achieve such levels of economic
performance or repay principal or interest when due may result in the
cancellation of such third parties' commitments to lend funds to the
governmental entity, which may further impair such debtor's ability or
willingness to service its debts in a timely manner. Consequently, governmental
entities may default on their sovereign debt. Holders of sovereign debt
(including the Funds) may be requested to participate in the rescheduling of
such debt and to extend further loans to governmental entities. There is no
bankruptcy proceeding by which sovereign debt on which governmental entities
have defaulted may be collected in whole or in part.

     A Fund's investments in foreign currency denominated debt obligations and
hedging activities will likely produce a difference between its book income and
its taxable income. This difference may cause a portion of the Fund's income
distributions to constitute returns of capital for tax purposes or require the
Fund to make distributions exceeding book income to qualify as a regulated
investment company for federal tax purposes.

     Each of the PIMCO Emerging Markets Bond Fund and PIMCO Emerging Markets
Bond Fund II will consider an issuer to be economically tied to a country with
an emerging securities market if (1) the issuer is organized under the laws of,
or maintains its principal place of business in, the country, (2) its securities
are principally traded in the country's securities markets, or (3) the issuer
derived at least half of its revenues or profits from goods produced or sold,
investments made, or services performed in the country, or has at least half of
its assets in that country.

Foreign Currency Transactions

     All Funds that may invest in foreign currency-denominated securities also
may purchase and sell foreign currency options and foreign currency futures
contracts and related options (see "Derivative Instruments"), and may engage in
foreign currency transactions either on a spot (cash) basis at the rate
prevailing in the currency exchange market at the time or through forward
currency contracts ("forwards") with terms generally of less than one year.
Funds may engage in these transactions in order to protect against uncertainty
in the level of future foreign exchange rates in the purchase and sale of
securities. The Funds may also use foreign currency options and foreign currency
forward contracts to increase exposure to a foreign currency or to shift
exposure to foreign currency fluctuations from one country to another.

     A forward involves an obligation to purchase or sell a specific currency at
a future date, which may be any fixed number of days from the date of the
contract agreed upon by the parties, at a price set at the time of the contract.
These contracts may be bought or sold to protect a Fund against a possible loss
resulting from an adverse change in the relationship between foreign currencies
and the U.S. dollar or to increase exposure to a particular foreign currency.
Open positions in forwards used for non-hedging purposes will be covered by the
segregation with the Trust's custodian of assets determined to be liquid by the
Adviser in accordance with procedures established by the Board of Trustees, and
are marked to market daily. Although forwards are intended to minimize the risk
of loss due to a decline in the value of the hedged currencies, at the same
time, they tend to limit any potential gain which might result should the value
of such currencies increase. Forwards will be used primarily to adjust the
foreign exchange exposure of each Fund with a view to protecting the outlook,
and the Funds might be expected to enter into such contracts under the following
circumstances:

     Lock In.  When the Adviser desires to lock in the U.S. dollar price on the
purchase or sale of a security denominated in a foreign currency.

     Cross Hedge. If a particular currency is expected to decrease against
another currency, a Fund may sell the currency expected to decrease and purchase
a currency which is expected to increase against the currency sold in an amount
approximately equal to some or all of the Fund's portfolio holdings denominated
in the currency sold.

                                       11
<PAGE>

     Direct Hedge. If the Adviser wants to a eliminate substantially all of the
risk of owning a particular currency, and/or if the Adviser thinks that a Fund
can benefit from price appreciation in a given country's bonds but does not want
to hold the currency, it may employ a direct hedge back into the U.S. dollar. In
either case, a Fund would enter into a forward contract to sell the currency in
which a portfolio security is denominated and purchase U.S. dollars at an
exchange rate established at the time it initiated the contract. The cost of the
direct hedge transaction may offset most, if not all, of the yield advantage
offered by the foreign security, but a Fund would hope to benefit from an
increase (if any) in value of the bond.

     Proxy Hedge. The Adviser might choose to use a proxy hedge, which may be
less costly than a direct hedge. In this case, a Fund, having purchased a
security, will sell a currency whose value is believed to be closely linked to
the currency in which the security is denominated. Interest rates prevailing in
the country whose currency was sold would be expected to be closer to those in
the U.S. and lower than those of securities denominated in the currency of the
original holding. This type of hedging entails greater risk than a direct hedge
because it is dependent on a stable relationship between the two currencies
paired as proxies and the relationships can be very unstable at times.

     Costs of Hedging. When a Fund purchases a foreign bond with a higher
interest rate than is available on U.S. bonds of a similar maturity, the
additional yield on the foreign bond could be substantially reduced or lost if
the Fund were to enter into a direct hedge by selling the foreign currency and
purchasing the U.S. dollar. This is what is known as the "cost" of hedging.
Proxy hedging attempts to reduce this cost through an indirect hedge back to the
U.S. dollar.

     It is important to note that hedging costs are treated as capital
transactions and are not, therefore, deducted from a Fund's dividend
distribution and are not reflected in its yield. Instead such costs will, over
time, be reflected in a Fund's net asset value per share.

     Tax Consequences of Hedging. Under applicable tax law, the Funds may be
required to limit their gains from hedging in foreign currency forwards,
futures, and options. Although the Funds are expected to comply with such
limits, the extent to which these limits apply is subject to tax regulations as
yet unissued. Hedging may also result in the application of the marked-to-
market and straddle provisions of the Internal Revenue Code. Those provisions
could result in an increase (or decrease) in the amount of taxable dividends
paid by the Funds and could affect whether dividends paid by the Funds are
classified as capital gains or ordinary income.

Foreign Currency Exchange-Related Securities

     Foreign currency warrants. Foreign currency warrants such as Currency
Exchange WarrantsSM ("CEWsSM") are warrants which entitle the holder to receive
from their issuer an amount of cash (generally, for warrants issued in the
United States, in U.S. dollars) which is calculated pursuant to a predetermined
formula and based on the exchange rate between a specified foreign currency and
the U.S. dollar as of the exercise date of the warrant. Foreign currency
warrants generally are exercisable upon their issuance and expire as of a
specified date and time. Foreign currency warrants have been issued in
connection with U.S. dollar-denominated debt offerings by major corporate
issuers in an attempt to reduce the foreign currency exchange risk which, from
the point of view of prospective purchasers of the securities, is inherent in
the international fixed-income marketplace. Foreign currency warrants may
attempt to reduce the foreign exchange risk assumed by purchasers of a security
by, for example, providing for a supplemental payment in the event that the U.S.
dollar depreciates against the value of a major foreign currency such as the
Japanese Yen or German Deutschmark. The formula used to determine the amount
payable upon exercise of a foreign currency warrant may make the warrant
worthless unless the applicable foreign currency exchange rate moves in a
particular direction (e.g., unless the U.S. dollar appreciates or depreciates
against the particular foreign currency to which the warrant is linked or
indexed). Foreign currency warrants are severable from the debt obligations with
which they may be offered, and may be listed on exchanges. Foreign currency
warrants may be

                                       12
<PAGE>

exercisable only in certain minimum amounts, and an investor wishing to exercise
warrants who possesses less than the minimum number required for exercise may be
required either to sell the warrants or to purchase additional warrants, thereby
incurring additional transaction costs. In the case of any exercise of warrants,
there may be a time delay between the time a holder of warrants gives
instructions to exercise and the time the exchange rate relating to exercise is
determined, during which time the exchange rate could change significantly,
thereby affecting both the market and cash settlement values of the warrants
being exercised. The expiration date of the warrants may be accelerated if the
warrants should be delisted from an exchange or if their trading should be
suspended permanently, which would result in the loss of any remaining "time
value" of the warrants (i.e., the difference between the current market value
and the exercise value of the warrants), and, in the case the warrants were
"out-of-the-money," in a total loss of the purchase price of the warrants.
Warrants are generally unsecured obligations of their issuers and are not
standardized foreign currency options issued by the Options Clearing Corporation
("OCC"). Unlike foreign currency options issued by OCC, the terms of foreign
exchange warrants generally will not be amended in the event of governmental or
regulatory actions affecting exchange rates or in the event of the imposition of
other regulatory controls affecting the international currency markets. The
initial public offering price of foreign currency warrants is generally
considerably in excess of the price that a commercial user of foreign currencies
might pay in the interbank market for a comparable option involving
significantly larger amounts of foreign currencies. Foreign currency warrants
are subject to significant foreign exchange risk, including risks arising from
complex political or economic factors.

     Principal exchange rate linked securities. Principal exchange rate linked
securities ("PERLsSM") are debt obligations the principal on which is payable at
maturity in an amount that may vary based on the exchange rate between the U.S.
dollar and a particular foreign currency at or about that time. The return on
"standard" principal exchange rate linked securities is enhanced if the foreign
currency to which the security is linked appreciates against the U.S. dollar,
and is adversely affected by increases in the foreign exchange value of the U.S.
dollar; "reverse" principal exchange rate linked securities are like the
"standard" securities, except that their return is enhanced by increases in the
value of the U.S. dollar and adversely impacted by increases in the value of
foreign currency. Interest payments on the securities are generally made in U.S.
dollars at rates that reflect the degree of foreign currency risk assumed or
given up by the purchaser of the notes (i.e., at relatively higher interest
rates if the purchaser has assumed some of the foreign exchange risk, or
relatively lower interest rates if the issuer has assumed some of the foreign
exchange risk, based on the expectations of the current market). Principal
exchange rate linked securities may in limited cases be subject to acceleration
of maturity (generally, not without the consent of the holders of the
securities), which may have an adverse impact on the value of the principal
payment to be made at maturity.

     Performance indexed paper. Performance indexed paper ("PIPsSM") is U.S.
dollar-denominated commercial paper the yield of which is linked to certain
foreign exchange rate movements. The yield to the investor on performance
indexed paper is established at maturity as a function of spot exchange rates
between the U.S. dollar and a designated currency as of or about that time
(generally, the index maturity two days prior to maturity). The yield to the
investor will be within a range stipulated at the time of purchase of the
obligation, generally with a guaranteed minimum rate of return that is below,
and a potential maximum rate of return that is above, market yields on U.S.
dollar-denominated commercial paper, with both the minimum and maximum rates of
return on the investment corresponding to the minimum and maximum values of the
spot exchange rate two business days prior to maturity.

Bank Obligations

     Bank obligations in which the Funds may invest include certificates of
deposit, bankers' acceptances, and fixed time deposits. Certificates of deposit
are negotiable certificates issued against funds deposited in a commercial bank
for a definite period of time and earning a specified return. Bankers'
acceptances are negotiable drafts or bills of exchange, normally drawn by an
importer or

                                       13
<PAGE>

exporter to pay for specific merchandise, which are "accepted" by a bank,
meaning, in effect, that the bank unconditionally agrees to pay the face value
of the instrument on maturity. Fixed time deposits are bank obligations payable
at a stated maturity date and bearing interest at a fixed rate. Fixed time
deposits may be withdrawn on demand by the investor, but may be subject to early
withdrawal penalties which vary depending upon market conditions and the
remaining maturity of the obligation. There are no contractual restrictions on
the right to transfer a beneficial interest in a fixed time deposit to a third
party, although there is no market for such deposits. A Fund will not invest in
fixed time deposits which (1) are not subject to prepayment or (2) provide for
withdrawal penalties upon prepayment (other than overnight deposits) if, in the
aggregate, more than 15% of its net assets (10% in the case of the PIMCO Money
Market Fund) would be invested in such deposits, repurchase agreements maturing
in more than seven days and other illiquid assets.

     The PIMCO Money Market, Low Duration Mortgage, Total Return Mortgage,
Commercial Mortgage Securities, High Yield and Long-Term U.S. Government Funds
may invest in the same types of bank obligations as the other Funds, but they
must be U.S. dollar-denominated. Subject to the Trust's limitation on
concentration of no more than 25% of its assets in the securities of issuers in
a particular industry, there is no limitation on the amount of a Fund's assets
which may be invested in obligations of foreign banks which meet the conditions
set forth herein.

     Obligations of foreign banks involve somewhat different investment risks
than those affecting obligations of United States banks, including the
possibilities that their liquidity could be impaired because of future political
and economic developments, that their obligations may be less marketable than
comparable obligations of United States banks, that a foreign jurisdiction might
impose withholding taxes on interest income payable on those obligations, that
foreign deposits may be seized or nationalized, that foreign governmental
restrictions such as exchange controls may be adopted which might adversely
affect the payment of principal and interest on those obligations and that the
selection of those obligations may be more difficult because there may be less
publicly available information concerning foreign banks or the accounting,
auditing and financial reporting standards, practices and requirements
applicable to foreign banks may differ from those applicable to United States
banks. Foreign banks are not generally subject to examination by any U.S.
Government agency or instrumentality.

Loan Participations

     Each Fund (except the PIMCO Municipal Bond Fund) may purchase
participations in commercial loans. Such indebtedness may be secured or
unsecured. Loan participations typically represent direct participation in a
loan to a corporate borrower, and generally are offered by banks or other
financial institutions or lending syndicates. The Funds may participate in such
syndications, or can buy part of a loan, becoming a part lender. When purchasing
loan participations, a Fund assumes the credit risk associated with the
corporate borrower and may assume the credit risk associated with an interposed
bank or other financial intermediary. The participation interests in which a
Fund intends to invest may not be rated by any nationally recognized rating
service.

     A loan is often administered by an agent bank acting as agent for all
holders. The agent bank administers the terms of the loan, as specified in the
loan agreement. In addition, the agent bank is normally responsible for the
collection of principal and interest payments from the corporate borrower and
the apportionment of these payments to the credit of all institutions which are
parties to the loan agreement. Unless, under the terms of the loan or other
indebtedness, a Fund has direct recourse against the corporate borrower, the
Fund may have to rely on the agent bank or other financial intermediary to apply
appropriate credit remedies against a corporate borrower.

     A financial institution's employment as agent bank might be terminated in
the event that it fails to observe a requisite standard of care or becomes
insolvent. A successor agent bank would generally be appointed to replace the
terminated agent bank, and assets held by the agent bank under the loan

                                       14
<PAGE>

agreement should remain available to holders of such indebtedness. However, if
assets held by the agent bank for the benefit of a Fund were determined to be
subject to the claims of the agent bank's general creditors, the Fund might
incur certain costs and delays in realizing payment on a loan or loan
participation and could suffer a loss of principal and/or interest. In
situations involving other interposed financial institutions (e.g., an insurance
company or governmental agency) similar risks may arise.

     Purchasers of loans and other forms of direct indebtedness depend primarily
upon the creditworthiness of the corporate borrower for payment of principal and
interest. If a Fund does not receive scheduled interest or principal payments on
such indebtedness, the Fund's share price and yield could be adversely affected.
Loans that are fully secured offer a Fund more protection than an unsecured loan
in the event of non-payment of scheduled interest or principal. However, there
is no assurance that the liquidation of collateral from a secured loan would
satisfy the corporate borrower's obligation, or that the collateral can be
liquidated.

     The Funds may invest in loan participations with credit quality comparable
to that of issuers of its securities investments. Indebtedness of companies
whose creditworthiness is poor involves substantially greater risks, and may be
highly speculative. Some companies may never pay off their indebtedness, or may
pay only a small fraction of the amount owed. Consequently, when investing in
indebtedness of companies with poor credit, a Fund bears a substantial risk of
losing the entire amount invested.

     Each Fund limits the amount of its total assets that it will invest in any
one issuer or in issuers within the same industry (see "Investment
Restrictions"). For purposes of these limits, a Fund generally will treat the
corporate borrower as the "issuer" of indebtedness held by the Fund. In the case
of loan participations where a bank or other lending institution serves as a
financial intermediary between a Fund and the corporate borrower, if the
participation does not shift to the Fund the direct debtor-creditor relationship
with the corporate borrower, Securities and Exchange Commission ("SEC")
interpretations require the Fund to treat both the lending bank or other lending
institution and the corporate borrower as "issuers" for the purposes of
determining whether the Fund has invested more than 5% of its total assets in a
single issuer. Treating a financial intermediary as an issuer of indebtedness
may restrict a Funds' ability to invest in indebtedness related to a single
financial intermediary, or a group of intermediaries engaged in the same
industry, even if the underlying borrowers represent many different companies
and industries.

     Loans and other types of direct indebtedness may not be readily marketable
and may be subject to restrictions on resale. In some cases, negotiations
involved in disposing of indebtedness may require weeks to complete.
Consequently, some indebtedness may be difficult or impossible to dispose of
readily at what the Adviser believes to be a fair price. In addition, valuation
of illiquid indebtedness involves a greater degree of judgment in determining a
Fund's net asset value than if that value were based on available market
quotations, and could result in significant variations in the Fund's daily share
price. At the same time, some loan interests are traded among certain financial
institutions and accordingly may be deemed liquid. As the market for different
types of indebtedness develops, the liquidity of these instruments is expected
to improve. In addition, the Funds currently intend to treat indebtedness for
which there is no readily available market as illiquid for purposes of the
Funds' limitation on illiquid investments. Investments in loan participations
are considered to be debt obligations for purposes of the Trust's investment
restriction relating to the lending of funds or assets by a Portfolio.

     Investments in loans through a direct assignment of the financial
institution's interests with respect to the loan may involve additional risks to
the Funds. For example, if a loan is foreclosed, a Fund could become part owner
of any collateral, and would bear the costs and liabilities associated with
owning and disposing of the collateral. In addition, it is conceivable that
under emerging legal theories of lender liability, a Fund could be held liable
as co-lender. It is unclear whether loans and other forms of direct indebtedness
offer securities law protections against fraud and misrepresentation. In the

                                       15
<PAGE>

absence of definitive regulatory guidance, the Funds rely on the Adviser's
research in an attempt to avoid situations where fraud or misrepresentation
could adversely affect the Funds.

Delayed Funding Loans and Revolving Credit Facilities

     The Funds (except the PIMCO Money Market and Municipal Bond Funds) may
enter into, or acquire participations in, delayed funding loans and revolving
credit facilities. Delayed funding loans and revolving credit facilities are
borrowing arrangements in which the lender agrees to make loans up to a maximum
amount upon demand by the borrower during a specified term. A revolving credit
facility differs from a delayed funding loan in that as the borrower repays the
loan, an amount equal to the repayment may be borrowed again during the term of
the revolving credit facility. Delayed funding loans and revolving credit
facilities usually provide for floating or variable rates of interest. These
commitments may have the effect of requiring a Fund to increase its investment
in a company at a time when it might not otherwise decide to do so (including at
a time when the company's financial condition makes it unlikely that such
amounts will be repaid). To the extent that a Fund is committed to advance
additional funds, it will at all times segregate assets, determined to be liquid
by the Adviser in accordance with procedures established by the Board of
Trustees, in an amount sufficient to meet such commitments. The Funds may invest
in delayed funding loans and revolving credit facilities with credit quality
comparable to that of issuers of its securities investments. Delayed funding
loans and revolving credit facilities may be subject to restrictions on
transfer, and only limited opportunities may exist to resell such instruments.
As a result, a Fund may be unable to sell such investments at an opportune time
or may have to resell them at less than fair market value. The Funds currently
intend to treat delayed funding loans and revolving credit facilities for which
there is no readily available market as illiquid for purposes of the Funds'
limitation on illiquid investments. For a further discussion of the risks
involved in investing in loan participations and other forms of direct
indebtedness see "Loan Participations." Participation interests in revolving
credit facilities will be subject to the limitations discussed in "Loan
Participations." Delayed funding loans and revolving credit facilities are
considered to be debt obligations for purposes of the Trust's investment
restriction relating to the lending of funds or assets by a Portfolio.

Loans of Portfolio Securities

     For the purpose of achieving income, each Fund may lend its portfolio
securities to brokers, dealers, and other financial institutions, provided: (i)
the loan is secured continuously by collateral consisting of U.S. Government
securities, cash or cash equivalents (negotiable certificates of deposits,
bankers' acceptances or letters of credit) maintained on a daily mark-to-market
basis in an amount at least equal to the current market value of the securities
loaned; (ii) the Fund may at any time call the loan and obtain the return of the
securities loaned; (iii) the Fund will receive any interest or dividends paid on
the loaned securities; and (iv) the aggregate market value of securities loaned
will not at any time exceed 331/3% (25% in the case of the Global Bond Fund II)
of the total assets of the Fund.

Short Sales

     Certain of the Funds, particularly the PIMCO StocksPLUS Short Strategy
Fund, may make short sales of securities as part of their overall portfolio
management strategies involving the use of derivative instruments and to offset
potential declines in long positions in similar securities. A short sale is a
transaction in which a Fund sells a security it does not own in anticipation
that the market price of that security will decline.

     When a Fund makes a short sale, it must borrow the security sold short and
deliver it to the broker-dealer through which it made the short sale as
collateral for its obligation to deliver the security upon conclusion of the
sale. The Fund may have to pay a fee to borrow particular securities and is
often obligated to pay over any accrued interest and dividends on such borrowed
securities.

                                       16
<PAGE>

     If the price of the security sold short increases between the time of the
short sale and the time and the Fund replaces the borrowed security, the Fund
will incur a loss; conversely, if the price declines, the Fund will realize a
capital gain. Any gain will be decreased, and any loss increased, by the
transaction costs described above. The successful use of short selling may be
adversely affected by imperfect correlation between movements in the price of
the security sold short and the securities being hedged.

     To the extent that a Fund engages in short sales, it will provide
collateral to the broker-dealer and (except in the case of short sales "against
the box") will maintain additional asset coverage in the form of segregated
assets determined to be liquid by the Adviser in accordance with procedures
established by the Board of Trustees. Each Fund, except the PIMCO StocksPLUS
Short Strategy Fund, does not intend to enter into short sales (other than those
"against the box") if immediately after such sale the aggregate of the value of
all collateral plus the amount of the segregated assets exceeds one-third of the
value of the Fund's net assets. This percentage may be varied by action of the
Trustees. A short sale is "against the box" to the extent that the Fund
contemporaneously owns, or has the right to obtain at no added cost, securities
identical to those sold short. The Funds will engage in short selling to the
extent permitted by the 1940 Act and rules and interpretations thereunder. The
PIMCO Global Bond Fund II may only engage in short sales that are "against the
box."

When-Issued, Delayed Delivery and Forward Commitment Transactions

     Each of the Funds may purchase or sell securities on a when-issued, delayed
delivery, or forward commitment basis. When such purchases are outstanding, the
Fund will segregate until the settlement date assets determined to be liquid by
the Adviser in accordance with procedures established by the Board of Trustees,
in an amount sufficient to meet the purchase price. Typically, no income accrues
on securities a Fund has committed to purchase prior to the time delivery of the
securities is made, although a Fund may earn income on securities it has
segregated.

     When purchasing a security on a when-issued, delayed delivery, or forward
commitment basis, the Fund assumes the rights and risks of ownership of the
security, including the risk of price and yield fluctuations, and takes such
fluctuations into account when determining its net asset value. Because the Fund
is not required to pay for the security until the delivery date, these risks are
in addition to the risks associated with the Fund's other investments. If the
Fund remains substantially fully invested at a time when when-issued, delayed
delivery, or forward commitment purchases are outstanding, the purchases may
result in a form of leverage.

     When the Fund has sold a security on a when-issued, delayed delivery, or
forward commitment basis, the Fund does not participate in future gains or
losses with respect to the security. If the other party to a transaction fails
to deliver or pay for the securities, the Fund could miss a favorable price or
yield opportunity or could suffer a loss. A Fund may dispose of or renegotiate a
transaction after it is entered into, and may sell when-issued, delayed delivery
or forward commitment securities before they are delivered, which may result in
a capital gain or loss. There is no percentage limitation on the extent to which
the Funds may purchase or sell securities on a when-issued, delayed delivery, or
forward commitment basis.

Derivative Instruments

     In pursuing their individual objectives the Funds (except the PIMCO Money
Market Fund) may purchase and sell (write) both put options and call options on
securities, securities indexes, and foreign currencies, and enter into interest
rate, foreign currency and index futures contracts and purchase and sell options
on such futures contracts ("futures options") for hedging purposes or as part of
their overall investment strategies, except that those Funds that may not invest
in foreign currency-denominated securities may not enter into transactions
involving currency futures or options. The Funds (except the PIMCO Money Market,
Short Duration Municipal Income, Municipal Bond, California Intermediate

                                       17
<PAGE>

Municipal Bond and New York Intermediate Municipal Bond Funds) also may purchase
and sell foreign currency options for purposes of increasing exposure to a
foreign currency or to shift exposure to foreign currency fluctuations from one
country to another. The Funds (except the PIMCO Money Market and Municipal Bond
Funds) also may enter into swap agreements with respect to interest rates and
indexes of securities, and to the extent it may invest in foreign currency-
denominated securities, may enter into swap agreements with respect to foreign
currencies. The Funds may invest in structured notes. If other types of
financial instruments, including other types of options, futures contracts, or
futures options are traded in the future, a Fund may also use those instruments,
provided that the Trustees determine that their use is consistent with the
Fund's investment objective.

     The value of some derivative instruments in which the Funds invest may be
particularly sensitive to changes in prevailing interest rates, and, like the
other investments of the Funds, the ability of a Fund to successfully utilize
these instruments may depend in part upon the ability of the Adviser to forecast
interest rates and other economic factors correctly. If the Adviser incorrectly
forecasts such factors and has taken positions in derivative instruments
contrary to prevailing market trends, the Funds could be exposed to the risk of
loss.

     The Funds might not employ any of the strategies described below, and no
assurance can be given that any strategy used will succeed. If the Adviser
incorrectly forecasts interest rates, market values or other economic factors in
utilizing a derivatives strategy for a Fund, the Fund might have been in a
better position if it had not entered into the transaction at all. Also,
suitable derivative transactions may not be available in all circumstances. The
use of these strategies involves certain special risks, including a possible
imperfect correlation, or even no correlation, between price movements of
derivative instruments and price movements of related investments. While some
strategies involving derivative instruments can reduce the risk of loss, they
can also reduce the opportunity for gain or even result in losses by offsetting
favorable price movements in related investments or otherwise, due to the
possible inability of a Fund to purchase or sell a portfolio security at a time
that otherwise would be favorable or the possible need to sell a portfolio
security at a disadvantageous time because the Fund is required to maintain
asset coverage or offsetting positions in connection with transactions in
derivative instruments, and the possible inability of a Fund to close out or to
liquidate its derivatives positions. In addition, a Fund's use of such
instruments may cause the Fund to realize higher amounts of short-term capital
gains (generally taxed at ordinary income tax rates) than if it had not used
such instruments.

     Options on Securities and Indexes. A Fund may, to the extent specified
herein or in the Prospectuses, purchase and sell both put and call options on
fixed income or other securities or indexes in standardized contracts traded on
foreign or domestic securities exchanges, boards of trade, or similar entities,
or quoted on NASDAQ or on a regulated foreign over-the-counter market, and
agreements, sometimes called cash puts, which may accompany the purchase of a
new issue of bonds from a dealer.

     An option on a security (or index) is a contract that gives the holder of
the option, in return for a premium, the right to buy from (in the case of a
call) or sell to (in the case of a put) the writer of the option the security
underlying the option (or the cash value of the index) at a specified exercise
price at any time during the term of the option. The writer of an option on a
security has the obligation upon exercise of the option to deliver the
underlying security upon payment of the exercise price or to pay the exercise
price upon delivery of the underlying security. Upon exercise, the writer of an
option on an index is obligated to pay the difference between the cash value of
the index and the exercise price multiplied by the specified multiplier for the
index option. (An index is designed to reflect features of a particular
financial or securities market, a specific group of financial instruments or
securities, or certain economic indicators.)

     A Fund will write call options and put options only if they are "covered."
In the case of a call option on a security, the option is "covered" if the Fund
owns the security underlying the call or has an absolute and immediate right to
acquire that security without additional cash consideration (or, if additional
cash consideration is required, cash or other assets determined to be liquid by
the Adviser in

                                       18
<PAGE>

accordance with procedures established by the Board of Trustees, in such amount
are segregated by its custodian) upon conversion or exchange of other securities
held by the Fund. For a call option on an index, the option is covered if the
Fund maintains with its custodian assets determined to be liquid by the Adviser
in accordance with procedures established by the Board of Trustees, in an amount
equal to the contract value of the index. A call option is also covered if the
Fund holds a call on the same security or index as the call written where the
exercise price of the call held is (i) equal to or less than the exercise price
of the call written, or (ii) greater than the exercise price of the call
written, provided the difference is maintained by the Fund in segregated assets
determined to be liquid by the Adviser in accordance with procedures established
by the Board of Trustees. A put option on a security or an index is "covered" if
the Fund segregates assets determined to be liquid by the Adviser in accordance
with procedures established by the Board of Trustees equal to the exercise
price. A put option is also covered if the Fund holds a put on the same security
or index as the put written where the exercise price of the put held is (i)
equal to or greater than the exercise price of the put written, or (ii) less
than the exercise price of the put written, provided the difference is
maintained by the Fund in segregated assets determined to be liquid by the
Adviser in accordance with procedures established by the Board of Trustees.

     If an option written by a Fund expires unexercised, the Fund realizes a
capital gain equal to the premium received at the time the option was written.
If an option purchased by a Fund expires unexercised, the Fund realizes a
capital loss equal to the premium paid. Prior to the earlier of exercise or
expiration, an exchange traded option may be closed out by an offsetting
purchase or sale of an option of the same series (type, exchange, underlying
security or index, exercise price, and expiration). There can be no assurance,
however, that a closing purchase or sale transaction can be effected when the
Fund desires.

     A Fund may sell put or call options it has previously purchased, which
could result in a net gain or loss depending on whether the amount realized on
the sale is more or less than the premium and other transaction costs paid on
the put or call option which is sold. Prior to exercise or expiration, an option
may be closed out by an offsetting purchase or sale of an option of the same
series. A Fund will realize a capital gain from a closing purchase transaction
if the cost of the closing option is less than the premium received from writing
the option, or, if it is more, the Fund will realize a capital loss. If the
premium received from a closing sale transaction is more than the premium paid
to purchase the option, the Fund will realize a capital gain or, if it is less,
the Fund will realize a capital loss. The principal factors affecting the market
value of a put or a call option include supply and demand, interest rates, the
current market price of the underlying security or index in relation to the
exercise price of the option, the volatility of the underlying security or
index, and the time remaining until the expiration date.

     The premium paid for a put or call option purchased by a Fund is an asset
of the Fund. The premium received for an option written by a Fund is recorded as
a deferred credit. The value of an option purchased or written is marked to
market daily and is valued at the closing price on the exchange on which it is
traded or, if not traded on an exchange or no closing price is available, at the
mean between the last bid and asked prices.

     The Funds may write covered straddles consisting of a combination of a call
and a put written on the same underlying security. A straddle will be covered
when sufficient assets are deposited to meet the Funds' immediate obligations.
The Funds may use the same liquid assets to cover both the call and put options
where the exercise price of the call and put are the same, or the exercise price
of the call is higher than that of the put. In such cases, the Funds will also
segregate liquid assets equivalent to the amount, if any, by which the put is
"in the money."

     Risks Associated with Options on Securities and Indexes. There are several
risks associated with transactions in options on securities and on indexes. For
example, there are significant differences between the securities and options
markets that could result in an imperfect correlation between these markets,
causing a given transaction not to achieve its objectives. A decision as to
whether, when and

                                       19
<PAGE>

how to use options involves the exercise of skill and judgment, and even a
well-conceived transaction may be unsuccessful to some degree because of market
behavior or unexpected events.

     During the option period, the covered call writer has, in return for the
premium on the option, given up the opportunity to profit from a price increase
in the underlying security above the exercise price, but, as long as its
obligation as a writer continues, has retained the risk of loss should the price
of the underlying security decline. The writer of an option has no control over
the time when it may be required to fulfill its obligation as a writer of the
option. Once an option writer has received an exercise notice, it cannot effect
a closing purchase transaction in order to terminate its obligation under the
option and must deliver the underlying security at the exercise price. If a put
or call option purchased by the Fund is not sold when it has remaining value,
and if the market price of the underlying security remains equal to or greater
than the exercise price (in the case of a put), or remains less than or equal to
the exercise price (in the case of a call), the Fund will lose its entire
investment in the option. Also, where a put or call option on a particular
security is purchased to hedge against price movements in a related security,
the price of the put or call option may move more or less than the price of the
related security.

     There can be no assurance that a liquid market will exist when a Fund seeks
to close out an option position. If a Fund were unable to close out an option
that it had purchased on a security, it would have to exercise the option in
order to realize any profit or the option may expire worthless. If a Fund were
unable to close out a covered call option that it had written on a security, it
would not be able to sell the underlying security unless the option expired
without exercise. As the writer of a covered call option, a Fund forgoes, during
the option's life, the opportunity to profit from increases in the market value
of the security covering the call option above the sum of the premium and the
exercise price of the call.

     If trading were suspended in an option purchased by a Fund, the Fund would
not be able to close out the option. If restrictions on exercise were imposed,
the Fund might be unable to exercise an option it has purchased. Except to the
extent that a call option on an index written by the Fund is covered by an
option on the same index purchased by the Fund, movements in the index may
result in a loss to the Fund; however, such losses may be mitigated by changes
in the value of the Fund's securities during the period the option was
outstanding.

     Foreign Currency Options. Funds that invest in foreign currency-denominated
securities may buy or sell put and call options on foreign currencies. A Fund
may buy or sell put and call options on foreign currencies either on exchanges
or in the over-the-counter market. A put option on a foreign currency gives the
purchaser of the option the right to sell a foreign currency at the exercise
price until the option expires. A call option on a foreign currency gives the
purchaser of the option the right to purchase the currency at the exercise price
until the option expires. Currency options traded on U.S. or other exchanges may
be subject to position limits which may limit the ability of a Fund to reduce
foreign currency risk using such options. Over-the-counter options differ from
traded options in that they are two-party contracts with price and other terms
negotiated between buyer and seller, and generally do not have as much market
liquidity as exchange-traded options.

     Futures Contracts and Options on Futures Contracts. Each Fund (except the
PIMCO Money Market and Municipal Bond Funds) may invest in interest rate futures
contracts and options thereon ("futures options"), and to the extent it may
invest in foreign currency-denominated securities, may also invest in foreign
currency futures contracts and options thereon. The PIMCO Short Duration
Municipal Income, Municipal Bond, California Intermediate Municipal Bond and New
York Intermediate Municipal Bond Funds may purchase and sell futures contracts
on U.S. Government securities and Municipal Bonds, as well as purchase put and
call options on such futures contracts. The Strategic Balanced, Convertible,
StocksPLUS and StocksPLUS Short Strategy Funds may invest in interest
rate, stock index and foreign currency futures contracts and options thereon.

                                       20

     An interest rate, foreign currency or index futures contract provides for
the future sale by one party and purchase by another party of a specified
quantity of a financial instrument, foreign currency or the cash value of an
index at a specified price and time.  A futures contract on an index is an
agreement pursuant to which two parties agree to take or make delivery of an
amount of cash equal to the difference between the value of the index at the
close of the last trading day of the contract and the price at which the index
contract was originally written. Although the value of an index might be a
function of the value of certain specified securities, no physical delivery of
these securities is made.  A public market exists in futures contracts covering
a number of indexes as well as financial instruments and foreign currencies,
including: the S&P 500; the S&P Midcap 400; the Nikkei 225; the NYSE composite;
U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates; three-month U.S.
Treasury bills; 90-day commercial paper; bank certificates of deposit;
Eurodollar certificates of deposit; the Australian dollar; the Canadian dollar;
the British pound; the German mark; the Japanese yen; the French franc; the
Swiss franc; the Mexican peso; and certain multinational currencies, such as the
euro.  It is expected that other futures contracts will be developed and traded
in the future.

     A Fund may purchase and write call and put futures options, as specified
for that Fund in the Prospectuses.  Futures options possess many of the same
characteristics as options on securities and indexes (discussed above).  A
futures option gives the holder the right, in return for the premium paid, to
assume a long position (call) or short position (put) in a futures contract at a
specified exercise price at any time during the period of the option.  Upon
exercise of a call option, the holder acquires a long position in the futures
contract and the writer is assigned the opposite short position.  In the case of
a put option, the opposite is true.

     To comply with applicable rules of the Commodity Futures Trading Commission
("CFTC") under which the Trust and the Funds avoid being deemed a "commodity
pool" or a "commodity pool operator," each Fund intends generally to limit its
use of futures contracts and futures options to "bona fide hedging"
transactions, as such term is defined in applicable regulations, interpretations
and practice.  For example, a Fund might use futures contracts to hedge against
anticipated changes in interest rates that might adversely affect either the
value of the Fund's securities or the price of the securities which the Fund
intends to purchase.  A Fund's hedging activities may include sales of futures
contracts as an offset against the effect of expected increases in interest
rates, and purchases of futures contracts as an offset against the effect of
expected declines in interest rates.  Although other techniques could be used to
reduce that Fund's exposure to interest rate fluctuations, the Fund may be able
to hedge its exposure more effectively and perhaps at a lower cost by using
futures contracts and futures options.

     A Fund will only enter into futures contracts and futures options which are
standardized and traded on a U.S. or foreign exchange, board of trade, or
similar entity, or quoted on an automated quotation system.

     When a purchase or sale of a futures contract is made by a Fund, the Fund
is required to deposit with its custodian (or broker, if legally permitted) a
specified amount of assets determined to be liquid by the Adviser in accordance
with procedures established by the Board of Trustees ("initial margin").  The
margin required for a futures contract is set by the exchange on which the
contract is traded and may be modified during the term of the contract.  Margin
requirements on foreign exchanges may be different than U.S. exchanges.  The
initial margin is in the nature of a performance bond or good faith deposit on
the futures contract which is returned to the Fund upon termination of the
contract, assuming all contractual obligations have been satisfied.  Each Fund
expects to earn interest income on its initial margin deposits.  A futures
contract held by a Fund is valued daily at the official settlement price of the
exchange on which it is traded.  Each day the Fund pays or receives cash, called
"variation margin," equal to the daily change in value of the futures contract.
This process is known as "marking to market."  Variation margin does not
represent a borrowing or loan by a Fund but is instead a settlement between the
Fund and the broker of the amount one would owe the other if the futures
contract expired.  In computing daily net asset value, each Fund will mark to
market its open futures positions.

                                       21
<PAGE>

     A Fund is also required to deposit and maintain margin with respect to put
and call options on futures contracts written by it.  Such margin deposits will
vary depending on the nature of the underlying futures contract (and the related
initial margin requirements), the current market value of the option, and other
futures positions held by the Fund.

     Although some futures contracts call for making or taking delivery of the
underlying securities, generally these obligations are closed out prior to
delivery by offsetting purchases or sales of matching futures contracts (same
exchange, underlying security or index, and delivery month).  If an offsetting
purchase price is less than the original sale price, the Fund realizes a capital
gain, or if it is more, the Fund realizes a capital loss. Conversely, if an
offsetting sale price is more than the original purchase price, the Fund
realizes a capital gain, or if it is less, the Fund realizes a capital loss.
The transaction costs must also be included in these calculations.

     The Funds may write covered straddles consisting of a call and a put
written on the same underlying futures contract.  A straddle will be covered
when sufficient assets are deposited to meet the Funds' immediate obligations.
A Fund may use the same liquid assets to cover both the call and put options
where the exercise price of the call and put are the same, or the exercise price
of the call is higher than that of the put.  In such cases, the Funds will also
segregate liquid assets equivalent to the amount, if any, by which the put is
"in the money."

     Limitations on Use of Futures and Futures Options.  In general, the Funds
intend to enter into positions in futures contracts and related options only for
"bona fide hedging" purposes.  With respect to positions in futures and related
options that do not constitute bona fide hedging positions, a Fund will not
enter into a futures contract or futures option contract if, immediately
thereafter, the aggregate initial margin deposits relating to such positions
plus premiums paid by it for open futures option positions, less the amount by
which any such options are "in-the-money," would exceed 5% of the Fund's net
assets.  A call option is "in-the-money" if the value of the futures contract
that is the subject of the option exceeds the exercise price.  A put option is
"in-the-money" if the exercise price exceeds the value of the futures contract
that is the subject of the option.

     When purchasing a futures contract, a Fund will maintain with its custodian
(and mark-to-market on a daily basis) assets determined to be liquid by the
Adviser in accordance with procedures established by the Board of Trustees,
that, when added to the amounts deposited with a futures commission merchant as
margin, are equal to the market value of the futures contract. Alternatively,
the Fund may "cover" its position by purchasing a put option on the same futures
contract with a strike price as high or higher than the price of the contract
held by the Fund.

     When selling a futures contract, a Fund will maintain with its custodian
(and mark-to-market on a daily basis) assets determined to be liquid by the
Adviser in accordance with procedures established by the Board of Trustees, that
are equal to the market value of the instruments underlying the contract.
Alternatively, the Fund may "cover" its position by owning the instruments
underlying the contract (or, in the case of an index futures contract, a
portfolio with a volatility substantially similar to that of the index on which
the futures contract is based), or by holding a call option permitting the Fund
to purchase the same futures contract at a price no higher than the price of the
contract written by the Fund (or at a higher price if the difference is
maintained in liquid assets with the Trust's custodian).

     When selling a call option on a futures contract, a Fund will maintain with
its custodian (and mark-to-market on a daily basis) assets determined to be
liquid by the Adviser in accordance with procedures established by the Board of
Trustees, that, when added to the amounts deposited with a futures commission
merchant as margin, equal the total market value of the futures contract
underlying the call option. Alternatively, the Fund may cover its position by
entering into a long position in the same futures contract at a price no higher
than the strike price of the call option, by owning the instruments underlying
the futures contract, or by holding a separate call option permitting the Fund
to purchase the same futures contract at a price not higher than the strike
price of the call option sold by the Fund.

                                      22
<PAGE>

     When selling a put option on a futures contract, a Fund will maintain with
its custodian (and mark-to-market on a daily basis) assets determined to be
liquid by the Adviser in accordance with procedures established by the Board of
Trustees, that equal the purchase price of the futures contract, less any margin
on deposit.  Alternatively, the Fund may cover the position either by entering
into a short position in the same futures contract, or by owning a separate put
option permitting it to sell the same futures contract so long as the strike
price of the purchased put option is the same or higher than the strike price of
the put option sold by the Fund.

     To the extent that securities with maturities greater than one year are
used to segregate assets to cover a Fund's obligations under futures contracts
and related options, such use will not eliminate the risk of a form of leverage,
which may tend to exaggerate the effect on net asset value of any increase or
decrease in the market value of a Fund's portfolio, and may require liquidation
of portfolio positions when it is not advantageous to do so.  However, any
potential risk of leverage resulting from the use of securities with maturities
greater than one year may be mitigated by the overall duration limit on a Fund's
portfolio securities.  Thus, the use of a longer-term security may require a
Fund to hold offsetting short-term securities to balance the Fund's portfolio
such that the Fund's duration does not exceed the maximum permitted for the Fund
in the Prospectuses.

     The requirements for qualification as a regulated investment company also
may limit the extent to which a Fund may enter into futures, futures options or
forward contracts.  See "Taxation."

     Risks Associated with Futures and Futures Options.  There are several risks
associated with the use of futures contracts and futures options as hedging
techniques.  A purchase or sale of a futures contract may result in losses in
excess of the amount invested in the futures contract.  There can be no
guarantee that there will be a correlation between price movements in the
hedging vehicle and in the Fund securities being hedged.  In addition, there are
significant differences between the securities and futures markets that could
result in an imperfect correlation between the markets, causing a given hedge
not to achieve its objectives.  The degree of imperfection of correlation
depends on circumstances such as variations in speculative market demand for
futures and futures options on securities, including technical influences in
futures trading and futures options, and differences between the financial
instruments being hedged and the instruments underlying the standard contracts
available for trading in such respects as interest rate levels, maturities, and
creditworthiness of issuers.  A decision as to whether, when and how to hedge
involves the exercise of skill and judgment, and even a well-conceived hedge may
be unsuccessful to some degree because of market behavior or unexpected interest
rate trends.

     Futures contracts on U.S. Government securities historically have reacted
to an increase or decrease in interest rates in a manner similar to that in
which the underlying U.S. Government securities reacted.  To the extent,
however, that the PIMCO Municipal Bond Fund enters into such futures contracts,
the value of such futures will not vary in direct proportion to the value of the
Fund's holdings of Municipal Bonds (as defined below). Thus, the anticipated
spread between the price of the futures contract and the hedged security may be
distorted due to differences in the nature of the markets.  The spread also may
be distorted by differences in initial and variation margin requirements, the
liquidity of such markets and the participation of speculators in such markets.

     Futures exchanges may limit the amount of fluctuation permitted in certain
futures contract prices during a single trading day.  The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of the
current trading session.  Once the daily limit has been reached in a futures
contract subject to the limit, no more trades may be made on that day at a price
beyond that limit.  The daily limit governs only price movements during a
particular trading day and therefore does not limit potential losses because the
limit may work to prevent the liquidation of unfavorable positions.  For
example, futures prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some holders of futures contracts to
substantial losses.

                                       23
<PAGE>

     There can be no assurance that a liquid market will exist at a time when a
Fund seeks to close out a futures or a futures option position, and that Fund
would remain obligated to meet margin requirements until the position is closed.
In addition, many of the contracts discussed above are relatively new
instruments without a significant trading history.  As a result, there can be no
assurance that an active secondary market will develop or continue to exist.

     Additional Risks of Options on Securities, Futures Contracts, Options on
Futures Contracts, and Forward Currency Exchange Contracts and Options Thereon.
Options on securities, futures contracts, options on futures contracts, and
options on currencies may be traded on foreign exchanges. Such transactions may
not be regulated as effectively as similar transactions in the United States;
may not involve a clearing mechanism and related guarantees, and are subject to
the risk of governmental actions affecting trading in, or the prices of, foreign
securities.  The value of such positions also could be adversely affected by (i)
other complex foreign political, legal and economic factors, (ii) lesser
availability than in the United States of data on which to make trading
decisions, (iii) delays in the Trust's ability to act upon economic events
occurring in foreign markets during non-business hours in the United States,
(iv) the imposition of different exercise and settlement terms and procedures
and margin requirements than in the United States, and (v) lesser trading
volume.

     Swap Agreements.  Each Fund (except the PIMCO Money Market and Municipal
Bond Funds) may enter into interest rate, index and, to the extent it may invest
in foreign currency-denominated securities, currency exchange rate swap
agreements. These transactions are entered into in a attempt to obtain a
particular return when it is considered desirable to do so, possibly at a lower
cost to the Fund than if the Fund had invested directly in an instrument that
yielded that desired return.  Swap agreements are two party contracts entered
into primarily by institutional investors for periods ranging from a few weeks
to more than one year.  In a standard "swap" transaction, two parties agree to
exchange the returns (or differentials in rates of return) earned or realized on
particular predetermined investments or instruments, which may be adjusted for
an interest factor.  The gross returns to be exchanged or "swapped" between the
parties are generally calculated with respect to a "notional amount," i.e., the
return on or increase in value of a particular dollar amount invested at a
particular interest rate, in a particular foreign currency, or in a "basket" of
securities representing a particular index.  Forms of swap agreements include
interest rate caps, under which, in return for a premium, one party agrees to
make payments to the other to the extent that interest rates exceed a specified
rate, or "cap"; interest rate floors, under which, in return for a premium, one
party agrees to make payments to the other to the extent that interest rates
fall below a specified rate, or "floor"; and interest rate collars, under which
a party sells a cap and purchases a floor or vice versa in an attempt to protect
itself against interest rate movements exceeding given minimum or maximum
levels.

     Most swap agreements entered into by the Funds would calculate the
obligations of the parties to the agreement on a "net basis." Consequently, a
Fund's current obligations (or rights) under a swap agreement will generally be
equal only to the net amount to be paid or received under the agreement based on
the relative values of the positions held by each party to the agreement (the
"net amount"). A Fund's current obligations under a swap agreement will be
accrued daily (offset against any amounts owed to the Fund) and any accrued but
unpaid net amounts owed to a swap counterparty will be covered by the
segregation of assets determined to be liquid by the Adviser in accordance with
procedures established by the Board of Trustees, to avoid any potential
leveraging of the Fund's portfolio. Obligations under swap agreements so covered
will not be construed to be "senior securities" for purposes of the Fund's
investment restriction concerning senior securities. A Fund will not enter into
a swap agreement with any single party if the net amount owed or to be received
under existing contracts with that party would exceed 5% of the Fund's assets.

     Whether a Fund's use of swap agreements will be successful in furthering
its investment objective of total return will depend on the Adviser's ability to
predict correctly whether certain types of investments are likely to produce
greater returns than other investments.  Because they are two party contracts
and because they may have terms of greater than seven days, swap agreements may
be

                                       24
<PAGE>

considered to be illiquid. Moreover, a Fund bears the risk of loss of the amount
expected to be received under a swap agreement in the event of the default or
bankruptcy of a swap agreement counterparty. The Funds will enter into swap
agreements only with counterparties that meet certain standards of
creditworthiness (generally, such counterparties would have to be eligible
counterparties under the terms of the Funds' repurchase agreement guidelines).
Certain restrictions imposed on the Funds by the Internal Revenue Code may limit
the Funds' ability to use swap agreements. The swaps market is a relatively new
market and is largely unregulated. It is possible that developments in the swaps
market, including potential government regulation, could adversely affect a
Fund's ability to terminate existing swap agreements or to realize amounts to be
received under such agreements.

     Certain swap agreements are exempt from most provisions of the Commodity
Exchange Act ("CEA") and, therefore, are not regulated as futures or commodity
option transactions under the CEA, pursuant to regulations approved by the CFTC
effective February 22, 1993.  To qualify for this exemption, a swap agreement
must be entered into by "eligible participants," which includes the following,
provided the participants' total assets exceed established levels:  a bank or
trust company, savings association or credit union, insurance company,
investment company subject to regulation under the 1940 Act, commodity pool,
corporation, partnership, proprietorship, organization, trust or other entity,
employee benefit plan, governmental entity, broker-dealer, futures commission
merchant, natural person, or regulated foreign person.  To be eligible, natural
persons and most other entities must have total assets exceeding $10 million;
commodity pools and employee benefit plans must have assets exceeding $5
million.  In addition, an eligible swap transaction must meet three conditions.
First, the swap agreement may not be part of a fungible class of agreements that
are standardized as to their material economic terms.  Second, the
creditworthiness of parties with actual or potential obligations under the swap
agreement must be a material consideration in entering into or determining the
terms of the swap agreement, including pricing, cost or credit enhancement
terms.  Third, swap agreements may not be entered into and traded on or through
a multilateral transaction execution facility.

     This exemption is not exclusive, and participants may continue to rely on
existing exclusions for swaps, such as the Policy Statement issued in July 1989
which recognized a safe harbor for swap transactions from regulation as futures
or commodity option transactions under the CEA or its regulations. The Policy
Statement applies to swap transactions settled in cash that (1) have
individually tailored terms, (2) lack exchange-style offset and the use of a
clearing organization or margin system, (3) are undertaken in conjunction with a
line of business, and (4) are not marketed to the public.

     Structured Notes.  Structured notes are derivative debt securities, the
interest rate or principal of which is determined by an unrelated indicator.
Indexed securities include structured notes as well as securities other than
debt securities, the interest rate or principal of which is determined by an
unrelated indicator.  Indexed securities may include a multiplier that
multiplies the indexed element by a specified factor and, therefore, the value
of such securities may be very volatile.  To the extent a Fund invests in these
securities, however, the Adviser analyzes these securities in its overall
assessment of the effective duration of the Fund's portfolio in an effort to
monitor the Fund's interest rate risk.

Inflation-Indexed Bonds

     Inflation-indexed bonds are fixed income securities whose principal value
is periodically adjusted according to the rate of inflation. Two structures are
common. The U.S. Treasury and some other issuers use a structure that accrues
inflation into the principal value of the bond. Most other issuers pay out the
CPI accruals as part of a semiannual coupon.

     Inflation-indexed securities issued by the U.S. Treasury have maturities of
five, ten or thirty years,  although it is possible that securities with other
maturities will be issued in the future. The U.S. Treasury securities pay
interest on a semi-annual basis, equal to a fixed percentage of the inflation-
adjusted principal amount. For example, if a Fund purchased an inflation-indexed
bond with a par value of $1,000 and a 3% real rate of return coupon (payable
1.5% semi-annually), and inflation over the first

                                       25
<PAGE>

six months were 1%, the mid-year par value of the bond would be $1,010 and the
first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If
inflation during the second half of the year resulted in the whole years'
inflation equaling 3%, the end-of-year par value of the bond would be $1,030 and
the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

     If the periodic adjustment rate measuring inflation falls, the principal
value of inflation-indexed bonds will be adjusted downward, and consequently the
interest payable on these securities (calculated with respect to a smaller
principal amount) will be reduced. Repayment of the original bond principal upon
maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury
inflation-indexed bonds, even during a period of deflation. However, the current
market value of the bonds is not guaranteed, and will fluctuate. The Funds may
also invest in other inflation related bonds which may or may not provide a
similar guarantee. If a guarantee of principal is not provided, the adjusted
principal value of the bond repaid at maturity may be less than the original
principal.

     The value of inflation-indexed bonds is expected to change in response to
changes in real interest rates. Real interest rates in turn are tied to the
relationship between nominal interest rates and the rate of inflation.
Therefore, if inflation were to rise at a faster rate than nominal interest
rates, real interest rates might decline, leading to an increase in value of
inflation-indexed bonds. In contrast, if nominal interest rates increased at a
faster rate than inflation, real interest rates might rise, leading to a
decrease in value of inflation-indexed bonds.

     While these securities are expected to be protected from long-term
inflationary trends, short-term increases in inflation may lead to a decline in
value. If interest rates rise due to reasons other than inflation (for example,
due to changes in currency exchange rates), investors in these securities may
not be protected to the extent that the increase is not reflected in the bond's
inflation measure.

     The periodic adjustment of U.S. inflation-indexed bonds is tied to the
Consumer Price Index for Urban Consumers ("CPI-U"), which is calculated monthly
by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in
the cost of living, made up of components such as housing, food, transportation
and energy. Inflation-indexed bonds issued by a foreign government are generally
adjusted to reflect a comparable inflation index, calculated by that government.
There can be no assurance that the CPI-U or any foreign inflation index will
accurately measure the real rate of inflation in the prices of goods and
services. Moreover, there can be no assurance that the rate of inflation in a
foreign country will be correlated to the rate of inflation in the United
States.

     Any increase in the principal amount of an inflation-indexed bond will be
considered taxable ordinary income, even though investors do not receive their
principal until maturity.

Hybrid Instruments

     A hybrid instrument can combine the characteristics of securities, futures,
and options. For example, the principal amount or interest rate of a hybrid
could be tied (positively or negatively) to the price of some commodity,
currency or securities index or another interest rate (each a "benchmark"). The
interest rate or (unlike most fixed income securities) the principal amount
payable at maturity of a hybrid security may be increased or decreased,
depending on changes in the value of the benchmark.

     Hybrids can be used as an efficient means of pursuing a variety of
investment goals, including currency hedging, duration management, and increased
total return. Hybrids may not bear interest or pay dividends. The value of a
hybrid or its interest rate may be a multiple of a benchmark and, as a result,
may be leveraged and move (up or down) more steeply and rapidly than the
benchmark. These benchmarks may be sensitive to economic and political events,
such as commodity shortages and currency devaluations, which cannot be readily
foreseen by the purchaser of a hybrid. Under certain conditions, the redemption
value of a hybrid could be zero. Thus, an investment in a hybrid may entail
significant market risks that are not associated with a similar investment in a
traditional, U.S. dollar-

                                       26
<PAGE>

denominated bond that has a fixed principal amount and pays a fixed rate or
floating rate of interest. The purchase of hybrids also exposes a Fund to the
credit risk of the issuer of the hybrids. These risks may cause significant
fluctuations in the net asset value of the Fund. Accordingly, no Fund will
invest more than 5% of its assets in hybrid instruments.

     Certain issuers of structured products such as hybrid instruments may be
deemed to be investment companies as defined in the 1940 Act. As a result, the
Funds' investments in these products will be subject to limits applicable to
investments in investment companies and may be subject to restrictions contained
in the 1940 Act.

Event-Linked Bonds

     Event-linked bonds are fixed income securities, for which the return of
principal and payment of interest is contingent on the non-occurrence of a
specific "trigger" event, such as a hurricane, earthquake, or other physical or
weather-related phenomenon.  They may be issued by government agencies,
insurance companies, reinsurers, special purpose corporations or other on-shore
or off-shore entities. If a trigger event causes losses exceeding a specific
amount in the geographic region and time period specified in a bond, a Fund
investing in the bond may lose a portion or all of its principal invested in the
bond. If no trigger event occurs, the Fund will recover its principal plus
interest. For some event-linked bonds, the trigger event or losses may be based
on company-wide losses, index-portfolio losses, industry indices, or readings of
scientific instruments rather than specified actual losses. Often the event-
linked bonds provide for extensions of maturity that are mandatory, or optional
at the discretion of the issuer, in order to process and audit loss claims in
those cases where a trigger event has, or possibly has, occurred. In addition to
the specified trigger events, event-linked bonds may also expose the Fund to
certain unanticipated risks including but not limited to issuer (credit)
default, adverse regulatory or jurisdictional interpretations, and adverse tax
consequences.

     Event-linked bonds are a relatively new type of financial instrument. As
such, there is no significant trading history of these securities, and there can
be no assurance that a liquid market in these instruments will develop. See
"Illiquid Securities" below. Lack of a liquid market may impose the risk of
higher transaction costs and the possibility that a Fund may be forced to
liquidate positions when it would not be advantageous to do so. Event-linked
bonds are typically rated, and a Fund will only invest in catastrophe bonds that
meet the credit quality requirements for the Fund.

Warrants to Purchase Securities

     The Funds may invest in or acquire warrants to purchase equity or fixed
income securities. Bonds with warrants attached to purchase equity securities
have many characteristics of convertible bonds and their prices may, to some
degree, reflect the performance of the underlying stock.  Bonds also may be
issued with warrants attached to purchase additional fixed income securities at
the same coupon rate.  A decline in interest rates would permit a Fund to buy
additional bonds at the favorable rate or to sell the warrants at a profit.  If
interest rates rise, the warrants would generally expire with no value.

     A Fund will not invest more than 5% of its net assets, valued at the lower
of cost or market, in warrants to purchase securities.  Warrants acquired in
units or attached to securities will be deemed without value for purposes of
this restriction.

Illiquid Securities

     The Funds may invest up to 15% of their net assets in illiquid securities
(10% in the case of the PIMCO Money Market Fund).  The term "illiquid
securities" for this purpose means securities that cannot be disposed of within
seven days in the ordinary course of business at approximately the amount at
which a Fund has valued the securities.  Illiquid securities are considered to
include, among other things, written over-the-counter options, securities or
other liquid assets being used as cover for such

                                       27
<PAGE>

options, repurchase agreements with maturities in excess of seven days, certain
loan participation interests, fixed time deposits which are not subject to
prepayment or provide for withdrawal penalties upon prepayment (other than
overnight deposits), and other securities whose disposition is restricted under
the federal securities laws (other than securities issued pursuant to Rule 144A
under the 1933 Act and certain commercial paper that the Adviser has determined
to be liquid under procedures approved by the Board of Trustees).

     Illiquid securities may include privately placed securities, which are sold
directly to a small number of investors, usually institutions.  Unlike public
offerings, such securities are not registered under the federal securities laws.
Although certain of these securities may be readily sold, others may be
illiquid, and their sale may involve substantial delays and additional costs.

Municipal Bonds

     Each Fund may invest in securities issued by states, municipalities and
other political subdivisions, agencies, authorities and instrumentalities of
states and multi-state agencies or authorities.  It is a policy of the PIMCO
Short Duration Municipal Income, Municipal Bond, California Intermediate
Municipal Bond and New York Intermediate Municipal Bond Funds (collectively, the
"Municipal Funds") to have 80% of its net assets invested in debt obligations
the interest on which, in the opinion of bond counsel to the issuer at the time
of issuance, is exempt from federal income tax ("Municipal Bonds").  In the case
of the PIMCO California Intermediate Municipal Bond and New York Intermediate
Municipal Bond Funds, the Funds will invest, under normal circumstances, at
least 65% of their net assets in debt securities whose interest is, in the
opinion of bond counsel for the issuers at the time of issuance, exempt from
federal income tax and California or New York income tax, respectively.  The
ability of the Fund to invest in securities other than Municipal Bonds is
limited by a requirement of the Internal Revenue Code that at least 50% of the
Fund's total assets be invested in Municipal Bonds at the end of each calendar
quarter.  See "Taxes."

     The PIMCO Municipal Bond may, from time to time, invest more than 25% of
its assets in Municipal Bonds of issuers in California and New York, and, if so,
will be subject to the California and New York state-specific risks discussed in
the "Summary of Risks" section of the Prospectus and in this "Municipal Bonds"
section of this Statement of Additional Information but neither Fund has any
present intention to invest more than that amount in a particular state.

     Municipal Bonds share the attributes of debt/fixed income securities in
general, but are generally issued by states, municipalities and other political
subdivisions, agencies, authorities and instrumentalities of states and multi-
state agencies or authorities.   Specifically, California and New York Municipal
Bonds generally are issued by or on behalf of the State of California and New
York, respectively, and their political subdivisions and financing authorities,
and local governments. The Municipal Bonds which the Municipal Funds may
purchase include general obligation bonds and limited obligation bonds (or
revenue bonds), including industrial development bonds issued pursuant to former
federal tax law.  General obligation bonds are obligations involving the credit
of an issuer possessing taxing power and are payable from such issuer's general
revenues and not from any particular source.  Limited obligation bonds are
payable only from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source.  Tax-exempt private activity bonds and industrial
development bonds generally are also revenue bonds and thus are not payable from
the issuer's general revenues.  The credit and quality of private activity bonds
and industrial development bonds are usually related to the credit of the
corporate user of the facilities.  Payment of interest on and repayment of
principal of such bonds is the responsibility of the corporate user (and/or any
guarantor).

     Under the Internal Revenue Code, certain limited obligation bonds are
considered "private activity bonds" and interest paid on such bonds is treated
as an item of tax preference for purposes of calculating federal alternative
minimum tax liability.

                                       28
<PAGE>

     The Municipal Funds may invest in municipal lease obligations.  A lease is
not a full faith and credit obligation of the issuer and is usually backed only
by the borrowing government's unsecured pledge to make annual appropriations for
lease payments. There have been challenges to the legality of lease financing in
numerous states, and, from time to time, certain municipalities have considered
not appropriating money for lease payments. In deciding whether to purchase a
lease obligation, the Municipal Funds will assess the financial condition of the
borrower, the merits of the project, the level of public support for the
project, and the legislative history of lease financing in the state. These
securities may be less readily marketable than other municipals. A Municipal
Fund may also purchase unrated lease obligations if determined by the Adviser to
be of comparable quality to rated securities in which the Fund is permitted to
invest.

     The Municipal Funds may seek to enhance their yield through the purchase of
private placements. These securities are sold through private negotiations,
usually to institutions or mutual funds, and may have resale restrictions. Their
yields are usually higher than comparable public securities to compensate the
investor for their limited marketability. A Municipal Fund may not invest more
than 15% of its net assets in illiquid securities, including unmarketable
private placements.

     Some longer-term Municipal Bonds give the investor the right to "put" or
sell the security at par (face value) within a specified number of days
following the investor's request-usually one to seven days. This demand feature
enhances a security's liquidity by shortening its effective maturity and enables
it to trade at a price equal to or very close to par. If a demand feature
terminates prior to being exercised, a Municipal Fund would hold the longer-term
security, which could experience substantially more volatility.

     The Municipal Funds may invest in municipal warrants, which are essentially
call options on Municipal Bonds. In exchange for a premium, they give the
purchaser the right, but not the obligation, to purchase a Municipal Bond in the
future. A Municipal Fund might purchase a warrant to lock in forward supply in
an environment where the current issuance of bonds is sharply reduced. Like
options, warrants may expire worthless and they may have reduced liquidity.  A
Municipal Fund will not invest more than 5% of its net assets in municipal
warrants.

     The Municipal Funds may invest in Municipal Bonds with credit enhancements
such as letters of credit, municipal bond insurance and Standby Bond Purchase
Agreements ("SBPAs").  Letters of credit that are issued by a third party,
usually a bank, to enhance liquidity and ensure repayment of principal and any
accrued interest if the underlying Municipal Bond should default.  Municipal
bond insurance, which is usually purchased by the bond issuer from a private,
nongovernmental insurance company, provides an unconditional and irrevocable
guarantee that the insured bond's principal and interest will be paid when due.
Insurance does not guarantee the price of the bond or the share price of any
fund. The credit rating of an insured bond reflects the credit rating of the
insurer, based on its claims-paying ability. The obligation of a municipal bond
insurance company to pay a claim extends over the life of each insured bond.
Although defaults on insured Municipal Bonds have been low to date and municipal
bond insurers have met their claims, there is no assurance this will continue. A
higher-than-expected default rate could strain the insurer's loss reserves and
adversely affect its ability to pay claims to bondholders. The number of
municipal bond insurers is relatively small, and not all of them have the
highest rating. An SBPA is a liquidity facility provided to pay the purchase
price of bonds that cannot be re-marketed. The obligation of the liquidity
provider (usually a bank) is only to advance funds to purchase tendered bonds
that cannot be remarketed and does not cover principal or interest under any
other circumstances. The liquidity provider's obligations under the SBPA are
usually subject to numerous conditions, including the continued creditworthiness
of the underlying borrower.

     The Municipal Funds may invest in Residual Interest Bonds, which are
created by dividing the income stream provided by an underlying bond to create
two securities, one short term and one long term. The interest rate on the
short-term component is reset by an index or auction process normally every
seven to 35 days. After income is paid on the short-term securities at current
rates, the residual

                                       29
<PAGE>

income goes to the long-term securities. Therefore, rising short-term interest
rates result in lower income for the longer-term portion, and vice versa. The
longer-term bonds can be very volatile and may be less liquid than other
Municipal Bonds of comparable maturity. A Municipal Fund will not invest more
than 10% of its total assets in Residual Interest Bonds.

     The Municipal Funds also may invest in participation interests.
Participation interests are various types of securities created by converting
fixed rate bonds into short-term, variable rate certificates. These securities
have been developed in the secondary market to meet the demand for short-term,
tax-exempt securities. The Municipal Funds will invest only in securities deemed
tax-exempt by a nationally recognized bond counsel, but there is no guarantee
the interest will be exempt because the IRS has not issued a definitive ruling
on the matter.

     Municipal Bonds are subject to credit and market risk.  Generally, prices
of higher quality issues tend to fluctuate less with changes in market interest
rates than prices of lower quality issues and prices of longer maturity issues
tend to fluctuate more than prices of shorter maturity issues.

     The Municipal Funds may purchase and sell portfolio investments to take
advantage of changes or anticipated changes in yield relationships, markets or
economic conditions.  The Municipal Funds may also sell Municipal Bonds due to
changes in the Adviser's evaluation of the issuer or cash needs resulting from
redemption requests for Fund shares.  The secondary market for Municipal Bonds
typically has been less liquid than that for taxable debt/fixed income
securities, and this may affect the Fund's ability to sell particular Municipal
Bonds at then-current market prices, especially in periods when other investors
are attempting to sell the same securities.

     Prices and yields on Municipal Bonds are dependent on a variety of factors,
including general money- market conditions, the financial condition of the
issuer, general conditions of the Municipal Bond market, the size of a
particular offering, the maturity of the obligation and the rating of the issue.
A number of these factors, including the ratings of particular issues, are
subject to change from time to time. Information about the financial condition
of an issuer of Municipal Bonds may not be as extensive as that which is made
available by corporations whose securities are publicly traded.

     Obligations of issuers of Municipal Bonds are subject to the provisions of
bankruptcy, insolvency and other laws, such as the Federal Bankruptcy Reform Act
of 1978, affecting the rights and remedies of creditors. Congress or state
legislatures may seek to extend the time for payment of principal or interest,
or both, or to impose other constraints upon enforcement of such obligations.
There is also the possibility that as a result of litigation or other
conditions, the power or ability of issuers to meet their obligations for the
payment of interest and principal on their Municipal Bonds may be materially
affected or their obligations may be found to be invalid or unenforceable.  Such
litigation or conditions may from time to time have the effect of introducing
uncertainties in the market for Municipal Bonds or certain segments thereof, or
of materially affecting the credit risk with respect to particular bonds.
Adverse economic, business, legal or political developments might affect all or
a substantial portion of a Fund's Municipal Bonds in the same manner.  In
particular, the California and New York Intermediate Municipal Bond Funds are
subject to the risks inherent in concentrating investment in a particular state
or region.  The following summarizes information drawn from official statements,
and other public documents available relating to issues potentially affecting
securities offerings of the states of California and New York.  PIMCO has not
independently verified the information, but has no reason to believe that it is
not correct.

     California.  The California Intermediate Municipal Bond Fund may be
particularly affected by political, economic or regulatory developments
affecting the ability of California issuers to pay interest or repay principal.
Provisions of the California Constitution and State statutes which limit the
taxing and spending authority of California governmental entities may impair the
ability of California issuers to maintain debt service on their obligations.
Future California political and economic developments,

                                       30
<PAGE>

constitutional amendments, legislative measures, executive orders,
administrative regulations, litigation and voter initiatives could have an
adverse effect on the debt obligations of California issuers.

     Certain debt obligations held by the California Intermediate Municipal Bond
Fund may be obligations of issuers which rely in whole or in substantial part on
California state revenues for the continuance of their operations and payment of
their obligations.  Whether and to what extent the California Legislature will
continue to appropriate a portion of the State's General Fund to counties,
cities and their various entities, is not entirely certain.  To the extent local
entities do not receive money from the State to pay for their operations and
services, their ability to pay debt service on obligations held by the
California Intermediate Municipal Bond Fund may be impaired.

          Certain tax-exempt securities in which the California Intermediate
Municipal Bond Fund may invest may be obligations payable solely from the
revenues of specific institutions, or may be secured by specific properties,
which are subject to provisions of California law which could adversely affect
the holders of such obligations.  For example, the revenues of California health
care institutions may be subject to state laws, and California law limits the
remedies of a creditor secured by a mortgage or deed of trust on real property.

          California is the most populous state in the nation with a total
population estimated at 32.9 million.  The State now comprises 12.3% of the
nation's population and 12.5% of its total personal income.  Its economy is
broad and diversified with major concentrations in high technology research and
manufacturing, aerospace and defense-related manufacturing, trade,
entertainment, real estate, and financial services.  After experiencing strong
growth throughout much of the 1980s, from 1990-1993 the State suffered through a
severe recession, the worst since the 1930's, heavily influenced by large
cutbacks in defense/aerospace industries and military base closures and a major
drop in real estate construction.  California's economy has been recovering and
growing steadily stronger since the start of 1994, to the point where the
State's economic growth is outpacing the rest of the nation.  The unemployment
rate, while still higher than the national average, fell to an average of 5.9%
in 1998, compared to over 10% at the worst of the recession.  California's
economic recovery from the recession is continuing at a strong pace.  Recent
economic reports indicate that, while the rate of economic growth in California
is expected to moderate over the next year, the increases in employment and
income may exceed those of the nation as a whole.  The unsettled financial
situation occurring in certain Asian economies, and its spillover effect
elsewhere, may adversely affect the State's export-related industries and,
therefore, the State's rate of economic growth.

          Revenue bonds represent both obligations payable from State revenue-
producing enterprises and projects, which are not payable from the General Fund,
and conduit obligations payable only from revenues paid by private users of
facilities financed by such revenue bonds.  Such enterprises and projects
include transportation projects, various public works and exposition projects,
educational facilities (including the California State University and University
of California systems), housing, health facilities, and pollution control
facilities.

          In years past, because of the State's budget problems, the State's
General Obligation bonds were downgraded.  In 1996, however, citing California's
improving economy and budget situation,  Fitch and S&P raised their ratings from
A to A+.  In October, 1997, Fitch raised its rating from A+ to AA-referring to
the State's fundamental strengths, the extent of its economic recovery and the
return of financial stability.  In October 1998, Moody's raised its rating from
A1 to Aa3 citing the State's continuing economic recovery and a number of
actions taken to improve the State's credit condition, including the rebuilding
of cash and budget reserves.  There is no assurance that a particular rating
will continue for any given period of time or that any such rating will not be
revised downward or withdrawn entirely if, in the judgment of the agency
originally establishing the rating, circumstances so warrant.  A downward
revision or withdrawal of such ratings, or either of them, may have an effect on
the market price of the State Municipal Obligations in which the California
Intermediate Municipal Bond Fund invests.

                                       31
<PAGE>

     The State is party to numerous legal proceedings, many of which normally
occur in governmental operations and which, if decided against the State, might
require the State to make significant future expenditures or impair future
revenue sources.

     Constitutional and statutory amendments as well as budget developments may
affect the ability of California issuers to pay interest and principal on their
obligations.  The overall effect may depend upon whether a particular California
tax-exempt security is a general or limited obligation bond and on the type of
security provided for the bond.  It is possible that other measures affecting
the taxing or spending authority of California or its political subdivisions may
be approved or enacted in the future.

     New York.  Because the New York Intermediate Municipal Bond Fund
concentrates its investments in New York tax-exempt bonds, the Fund may be
affected significantly by economic or regulatory developments affecting the
ability of New York tax-exempt issuers to pay interest or repay principal.
Investors should be aware that certain issuers of New York tax-exempt securities
have experienced serious financial difficulties in recent years.  A reoccurrence
of these difficulties may impair the ability of certain New York issuers to
maintain debt service on their obligations.

     The economic and financial condition of the State also may be affected by
various financial, social, economic and political factors.  Such factors can be
very complex, may vary from year to year and are frequently the result of
actions taken not only by the State and its agencies and instrumentalities, but
also by entities, such as the Federal government, that are not under the control
of the State.

     The fiscal stability of New York State is related to the fiscal stability
of the State's municipalities, its agencies and authorities (which generally
finance, construct and operate revenue-producing public benefit facilities).
This is due in part to the fact that agencies, authorities and local governments
in financial trouble often seek State financial assistance.  The experience has
been that if New York City or any of the agencies or authorities suffers serious
financial difficulty, both the ability of the State, the City, the State's
political subdivisions, the agencies and the authorities to obtain financing in
the public credit markets and the market price of outstanding New York tax-
exempt securities are adversely affected.

     The New York state economy has continued to expand, but growth remains
somewhat slower than in the nation overall.  Although the State has added
approximately 400,000 jobs since late 1992, employment growth in the State has
been hindered during recent years by significant cutbacks in the computer and
instrument manufacturing, utility, defense and banking industries.

     In recent years, State actions affecting the level of receipts and
disbursements, the relative strength of the State and regional economy and
actions of the federal government have helped to create projected  budget gaps
for the State.  These gaps result from a significant disparity between recurring
revenues and the costs of maintaining or increasing the level of support for
State programs.  To address a potential imbalance in any given fiscal year, the
State would be required to take actions to increase receipts and/or reduce
disbursements as it enacts the budget for that year, and under the State
Constitution, the Governor is required to propose a balanced budget each year.
There can be no assurance, however, that the Legislature will enact the
Governor's proposals or that the State's actions will be sufficient to preserve
budgetary balance in a given fiscal year or to align recurring receipts and
disbursements in future fiscal years.

     The fiscal stability of the State is related to the fiscal stability of its
public authorities.  Authorities have various responsibilities, including those
which finance, construct and/or operate revenue-producing public facilities.
Authorities are not subject to the constitutional restrictions on the incurrence
of debt which apply to the State itself, and may issue bonds and notes within
the amounts and restrictions set forth in their legislative authorization.

                                       32
<PAGE>

     Authorities are generally supported by revenues generated by the projects
financed or operated, such as tolls charged for use of highways, bridges or
tunnels, charges for electric power, electric and gas utility services, rentals
charged for housing units and charges for occupancy at medical care facilities.
In addition, State legislation authorizes several financing techniques for
authorities.  Also, there are statutory arrangements providing for State local
assistance payments otherwise payable to localities to be made under certain
circumstances to authorities.  Although the State has no obligation to provide
additional assistance to localities whose local assistance payments have been
paid to authorities under these arrangements, if local assistance payments are
diverted the affected localities could seek additional State assistance.  Some
authorities also receive moneys from State appropriations to pay for the
operating costs of certain of their programs.

     S&P rates the State's general obligation bonds A, and Moody's rates the
State's general obligation bonds A2.  There is no assurance that a particular
rating will continue for any given period of time or that any such rating will
not be revised downward or withdrawn entirely if, in the judgment of the agency
originally establishing the rating, circumstances so warrant.  A downward
revision or withdrawal of such ratings, or either of them, may have an effect on
the market price of the State Municipal Obligations in which the New York
Intermediate Bond Fund invests.

     Over the long term, the State and New York City face potential economic
problems.  New York City accounts for a large portion of the State's population
and personal income, and New York City's financial health affects the State in
numerous ways.  New York City continues to require significant financial
assistance from the State.  New York  City depends on State aid both to enable
it to balance its budget and to meet its cash requirements.  The State could
also be affected by the ability of the City to market its securities
successfully in the public credit markets.

     Each Fund may purchase custodial receipts representing the right to receive
either the principal amount or the periodic interest payments or both with
respect to specific underlying Municipal Bonds.  In a typical custodial receipt
arrangement, an issuer or third party owner of Municipal Bonds deposits the
bonds with a custodian in exchange for two classes of custodial receipts.  The
two classes have different characteristics, but, in each case, payments on the
two classes are based on payments received on the underlying Municipal Bonds.
In no event will the aggregate interest paid with respect to the two classes
exceed the interest paid by the underlying Municipal Bond.  Custodial receipts
are sold in private placements.   The value of a custodial receipt may fluctuate
more than the value of a Municipal Bond of comparable quality and maturity.

Social Investment Policies

     The PIMCO Low Duration Fund III and PIMCO Total Return Fund III will not,
as a matter of non-fundamental operating policy, invest in the securities of any
issuer determined by the Adviser to be engaged principally in the provision of
healthcare services, the manufacture of alcoholic beverages, tobacco products,
pharmaceuticals, military equipment, or the operation of gambling casinos.  The
Funds will also avoid, to the extent possible on the basis of information
available to the Adviser, the purchase of securities of issuers engaged in the
production or trade of pornographic materials.  An issuer will be deemed to be
principally engaged in an activity if it derives more than 10% of its gross
revenues from such activities. Evaluation of any particular issuer with respect
to these criteria may involve the exercise of subjective judgment by the
Adviser.  The Adviser's determination of issuers engaged in such activities at
any given time will, however, be based upon its good faith interpretation of
available information and its continuing and reasonable best efforts to obtain
and evaluate the most current information available, and to utilize such
information, as it becomes available, promptly and expeditiously in portfolio
management for the Funds. In making its analysis, the Adviser may rely, among
other things, upon information contained in such publications as those produced
by the Investor Responsibility Research Center, Inc.

                            INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions

     Each Fund's investment objective, except for the PIMCO Global Bond Fund II,
as set forth in the Prospectuses under "Investment Objectives and Policies,"
together with the investment restrictions set forth below, are fundamental
policies of the Fund and may not be changed with respect to a Fund without
shareholder approval by vote of a majority of the outstanding shares of that
Fund.  Under these restrictions a Fund may not:

(1)  (a)  invest in a security if, as a result of such investment, more than 25%
     of its total assets (taken at market value at the time of such investment)
     would be invested in the securities of issuers in any particular industry,
     or, in the case of the Municipal Funds, in industrial development revenue
     bonds based, directly or indirectly, on the credit of private entities in
     any one industry; except that this restriction does not apply (a) to
     securities issued or guaranteed by the U.S. Government or its agencies or
     instrumentalities (or repurchase agreements with respect thereto) and (b)
     with respect to the Money Market Fund, to securities or obligations issued
     by U.S. banks.  Investments of the Municipal Funds in utilities, gas,
     electric, water and telephone companies will be considered as being in
     separate industries;

     (b) for the Global Bond Fund II, concentrate more than 25% of the value of
     its total assets in any one industry (The SEC staff takes the position that
     investments in government securities of a single foreign country (including
     agencies and instrumentalities of such government, to the extent such
     obligations are backed by the assets and revenues of such government)
     represent investments in a separate industry for these purposes.);

(2)  with respect to 75% of its assets, invest in a security if, as a result of
     such investment, more than 5% of its total assets (taken at market value at
     the time of such investment) would be invested in the securities of any one
     issuer, except that this restriction does not apply to securities issued or
     guaranteed by the U.S. Government or its agencies or instrumentalities
     (This investment restriction is not applicable to the Real Return Bond,
     Commercial Mortgage Securities, Global Bond, Global Bond II, Foreign Bond,
     International Bond, Emerging Markets Bond, Emerging Markets Bond II,
     California Intermediate Municipal Bond and New York Intermediate Municipal
     Bond Funds.). For the purpose of this restriction, each state and each
     separate political subdivision, agency, authority or instrumentality of
     such state, each multi-state agency or authority, and each guarantor, if
     any, are treated as separate issuers of Municipal Bonds;

(3)  with respect to 75% of its assets, invest in a security if, as a result of
     such investment, it would hold more than 10% (taken at the time of such
     investment) of the outstanding voting securities of any one issuer (This
     restriction is not applicable to the Real Return Bond, Commercial Mortgage
     Securities, Global Bond, Global Bond II, Foreign Bond, International Bond,
     Emerging Markets Bond, Emerging Markets Bond II, California Intermediate
     Municipal Bond and New York Intermediate Municipal Bond Funds.);

(4)  (a)  purchase or sell real estate, although it may purchase securities
     secured by real estate or interests therein, or securities issued by
     companies which invest in real estate, or interests therein;

     (b)  for the Global Bond Fund II, purchase or sell real estate, although it
     may purchase securities of issuers which deal in real estate, including
     securities of real estate investment trusts, and may purchase securities
     which are secured by interests in real estate;

                                       34

(5)  purchase or sell commodities or commodities contracts or oil, gas or
     mineral programs.  This restriction shall not prohibit a Fund, subject to
     restrictions described in the Prospectuses and elsewhere in this Statement
     of Additional Information, from purchasing, selling or entering into
     futures contracts, options on futures contracts, foreign currency forward
     contracts, foreign currency options, or any interest rate, securities-
     related or foreign currency-related hedging instrument, including swap
     agreements and other derivative instruments, subject to compliance with any
     applicable provisions of the federal securities or commodities laws (This
     restriction is not applicable to the Global Bond Fund II, but see non-
     fundamental restriction "F".);

(6)  for the Total Return III, High Yield, International Bond and StocksPLUS
     Funds:  purchase securities on margin, except for use of short-term credit
     necessary for clearance of purchases and sales of portfolio securities, but
     it may make margin deposits in connection with transactions in options,
     futures, and options on futures;

(7)  (a)  borrow money, issue senior securities, or pledge, mortgage or
     hypothecate its assets, except that a Fund may (i) borrow from banks or
     enter into reverse repurchase agreements, or employ similar investment
     techniques, and pledge its assets in connection therewith, but only if
     immediately after each borrowing there is asset coverage of 300% and (ii)
     enter into transactions in options, futures, options on futures, and other
     derivative instruments as described in the Prospectuses and in this
     Statement of Additional Information (the deposit of assets in escrow in
     connection with the writing of covered put and call options and the
     purchase of securities on a when-issued or delayed delivery basis,
     collateral arrangements with respect to initial or variation margin
     deposits for futures contracts and commitments entered into under swap
     agreements or other derivative instruments, will not be deemed to be
     pledges of a Fund's assets);

     (b) for the Global Bond Fund II, borrow money in excess of 10% of the value
     (taken at the lower of cost or current value) of the Fund's total assets
     (not including the amount borrowed) at the time the borrowing is made, and
     then only from banks as a temporary measure to facilitate the meeting of
     redemption requests (not for leverage) which might otherwise require the
     untimely disposition of portfolio investments or for extraordinary or
     emergency purposes (Such borrowings will be repaid before any additional
     investments are purchased.); or pledge, hypothecate, mortgage or otherwise
     encumber its assets in excess of 10% of the Fund's total assets (taken at
     cost) and then only to secure borrowings permitted above (The deposit of
     securities or cash or cash equivalents in escrow in connection with the
     writing of covered call or put options, respectively, is not deemed to be
     pledges or other encumbrances.  For the purpose of this restriction,
     collateral arrangements with respect to the writing of options, futures
     contracts, options on futures contracts, and collateral arrangements with
     respect to initial and variation margin are not deemed to be a pledge of
     assets and neither such arrangements nor the purchase or sale of futures or
     related options are deemed to be the issuance of a senior security.);

(8)  lend any funds or other assets, except that a Fund may, consistent with its
     investment objective and policies:  (a) invest in debt obligations,
     including bonds, debentures, or other debt securities, bankers' acceptances
     and commercial paper, even though the purchase of such obligations may be
     deemed to be the making of loans, (b) enter into repurchase agreements, and
     (c) lend its portfolio securities in an amount not to exceed one-third of
     the value of its total assets, provided such loans are made in accordance
     with applicable guidelines established by the Securities and Exchange
     Commission and the Trustees of the Trust (This restriction is not
     applicable to the Global Bond Fund II, but see non-fundamental restriction
     "G".);

(9)  (a)  act as an underwriter of securities of other issuers, except to the
     extent that in connection with the disposition of portfolio securities, it
     may be deemed to be an underwriter under the federal securities laws;

Non-Fundamental Investment Restrictions

     Each Fund is also subject to the following non-fundamental restrictions and
policies (which may be changed without shareholder approval) relating to the
investment of its assets and activities.  Unless otherwise indicated, a Fund may
not:

(A)  (a)  invest more than 15% of the net assets of a Fund (10% in the case of
     the PIMCO Money Market Fund) (taken at market value at the time of the
     investment) in "illiquid securities," illiquid securities being defined to
     include securities subject to legal or contractual restrictions on resale
     (which may include private placements), repurchase agreements maturing in
     more than seven days, certain loan participation interests, fixed time
     deposits which are not subject to prepayment or provide for withdrawal
     penalties upon prepayment (other than overnight deposits), certain options
     traded over the counter that a Fund has purchased, securities or other
     liquid assets being used to cover such options a Fund has written,
     securities for which market quotations are not readily available, or other
     securities which legally or in the Adviser's opinion may be deemed illiquid
     (other than securities issued pursuant to Rule 144A under the Securities
     Act of 1933 and certain commercial paper that PIMCO has determined to be
     liquid under procedures approved by the Board of Trustees);

     (b)  for the Global Bond Fund II, invest in (a) securities which at the
     time of such investment are not readily marketable, (b) securities the
     disposition of which is restricted under federal securities laws, (c)
     repurchase agreements maturing in more than seven days (d) OTC options (to
     the extent described below), and (e) IO/PO stripped mortgage-backed
     securities (as defined in the Prospectuses) if, as a result, more than 15%
     of the Fund's net assets, taken at current value, would then be invested in
     securities described in (a), (b), (c), (d) and (e) above (For the purpose
     of this restriction securities subject to a 7-day put option or convertible
     into readily saleable securities or commodities are not included with
     subsections (a) or (b).); or purchase securities the disposition of which
     is restricted under the federal securities laws (excluding for purposes of
     this restriction securities offered and sold pursuant to Rule 144A of the
     Securities Act of 1933 and Section 4(2) commercial paper) if, as a result,
     such investments would exceed 10% of the value of the net assets of the
     Fund;

(B)  (a)  for the PIMCO Money Market, Short-Term, Low Duration, Low Duration II,
     Low Duration III, Moderate Duration, Total Return, Total Return II,
     Commercial Mortgage Securities, Long-Term U.S. Government, Long Duration,
     Short Duration Municipal Income, Municipal Bond, California Intermediate
     Municipal Bond, New York Intermediate Municipal Bond, Global Bond, Foreign
     Bond, Strategic Balanced, Convertible and StocksPLUS Short Strategy Funds:
     purchase securities on margin, except for use of short-term credit
     necessary for clearance of purchases and sales of portfolio securities, but
     it may make margin deposits in connection with covered transactions in
     options, futures, options on futures and short positions;

                                       37
<PAGE>

     (b) for the Global Bond Fund II, purchase securities on margin, except such
     short-term credits as may be necessary for the clearance of purchases and
     sales of securities (For this purpose, the deposit or payment by the Fund
     of initial or variation margin in connection with futures contracts or
     related options transactions is not considered the purchase of a security
     on margin.);

(C)  invest more than 5% of the assets of a Fund (taken at market value at the
     time of investment) in any combination of interest only, principal only, or
     inverse floating rate securities (This restriction is not applicable to the
     Global Bond Fund II, but see fundamental investment restriction 7(b).);

(D)  borrow money (excluding uncovered dollar rolls, reverse repurchase
     agreements, sale-buybacks, and economically similar transactions, which are
     subject to the Fund's fundamental borrowing restriction), except for
     temporary administrative purposes (This restriction is not applicable to
     the Global Bond Fund II, but see fundamental investment restriction 7(b).);

(E)  for the Global Bond Fund II, make short sales of securities or maintain a
     short position for the account of the Fund unless at all times when a short
     position is open the Fund owns an equal amount of such securities or owns
     securities which, without payment of any further consideration, are
     convertible into or exchangeable for securities of the same issue as, and
     equal in amount to, the securities sold short;

(F)  for the Global Bond Fund II, purchase or sell commodities or commodity
     contracts except that the Fund may purchase and sell financial futures
     contracts and related options;

(G)  for the Global Bond Fund II, make loans, except by purchase of debt
     obligations or by entering into repurchase agreements or through the
     lending of the Fund's portfolio securities with respect to not more than
     25% of its total assets;

(H)  for the Global Bond Fund II, write (sell) or purchase options except that
     the Fund may (a) write covered call options or covered put options on
     securities that it is eligible to purchase (and on stock indices) and enter
     into closing purchase transactions with respect to such options, and (b) in
     combination therewith, or separately, purchase put and call options on
     securities it is eligible to purchase; provided that the premiums paid by
     the Fund on all outstanding options it has purchased do not exceed 5% of
     its total assets (The Fund may enter into closing sale transactions with
     respect to options it has purchased.);

     In addition, the Trust has adopted a non-fundamental policy pursuant to
which each Fund that may invest in securities denominated in foreign currencies,
except the PIMCO Global Bond, Emerging Markets Bond and Emerging Markets Bond II
Funds, will hedge at least 75% of its exposure to foreign currency using the
techniques described in the Prospectuses.  There can be no assurance that
currency hedging techniques will be successful.

     Under the 1940 Act, a "senior security" does not include any promissory
note or evidence of indebtedness where such loan is for temporary purposes only
and in an amount not exceeding 5% of the value of the total assets of the issuer
at the time the loan is made.  A loan is presumed to be for temporary purposes
if it is repaid within sixty days and is not extended or renewed.
Notwithstanding the provisions of fundamental investment restriction (7)(a)
above, a Fund may borrow money for temporary administrative purposes.  To the
extent that borrowings for temporary administrative purposes exceed 5% of the
total assets of a Fund (except the PIMCO Global Bond Fund II), such excess shall
be subject to the 300% asset coverage requirement of that restriction.

     To the extent a Fund covers its commitment under a reverse repurchase
agreement (or economically similar transaction) by the segregation of assets
determined to be liquid in accordance with

                                       38
<PAGE>

procedures adopted by the Trustees, equal in value to the amount of the Fund's
commitment to repurchase, such an agreement will not be considered a "senior
security" by the Fund and therefore will not be subject to the 300% asset
coverage requirement otherwise applicable to borrowings by the Fund.

     The staff of the SEC has taken the position that purchased over-the-counter
("OTC") options and the assets used as cover for written OTC options are
illiquid securities.  Therefore, the Funds have adopted an investment policy
pursuant to which a Fund will not purchase or sell OTC options if, as a result
of such transactions, the sum of the market value of OTC options currently
outstanding which are held by the Fund, the market value of the underlying
securities covered by OTC call options currently outstanding which were sold by
the Fund and margin deposits on the Fund's existing OTC options on futures
contracts exceeds 15% of the net assets of the Fund, taken at market value,
together with all other assets of the Fund which are illiquid or are otherwise
not readily marketable.  However, if an OTC option is sold by the Fund to a
primary U.S. Government securities dealer recognized by the Federal Reserve Bank
of New York and if the Fund has the unconditional contractual right to
repurchase such OTC option from the dealer at a predetermined price, then the
Fund will treat as illiquid such amount of the underlying securities equal to
the repurchase price less the amount by which the option is "in-the-money"
(i.e., current market value of the underlying securities minus the option's
strike price). The repurchase price with the primary dealers is typically a
formula price which is generally based on a multiple of the premium received for
the option, plus the amount by which the option is "in-the-money."  This policy
is not a fundamental policy of the Funds and may be amended by the Trustees
without the approval of shareholders. However, the Funds will not change or
modify this policy prior to the change or modification by the SEC staff of its
position.

     Unless otherwise indicated, all limitations applicable to Fund investments
(as stated above and elsewhere in this Statement of Additional Information)
apply only at the time a transaction is entered into. Any subsequent change in a
rating assigned by any rating service to a security (or, if unrated, deemed to
be of comparable quality), or change in the percentage of Fund assets invested
in certain securities or other instruments, or change in the average duration of
a Fund's investment portfolio, resulting from market fluctuations or other
changes in a Fund's total assets will not require a Fund to dispose of an
investment until the Adviser determines that it is practicable to sell or close
out the investment without undue market or tax consequences to the Fund.  In the
event that ratings services assign different ratings to the same security, the
Adviser will determine which rating it believes best reflects the security's
quality and risk at that time, which may be the higher of the several assigned
ratings.

     The Funds interpret their policies with respect to borrowing and lending to
permit such activities as may be lawful for the Funds, to the full extent
permitted by the 1940 Act or by exemption from the provisions therefrom pursuant
to exemptive order of the SEC.  The Funds have filed an application seeking an
order from the SEC to permit the Funds to enter into transactions among
themselves with respect to the investment of daily cash balances of the Funds in
shares of the PIMCO Money Market Fund, as well as the use of daily excess cash
balances of the PIMCO Money Market Fund in inter-fund lending transactions with
the other Funds for temporary cash management purposes.  The interest paid by a
Fund in such an arrangement will be less than that otherwise payable for an
overnight loan, and will be in excess of the overnight rate the PIMCO Money
Market Fund could otherwise earn as lender in such a transaction.

Non-Fundamental Operating Policies Relating to the Sale of Shares of PIMCO Total
Return Fund in Japan

     In connection with an offering of Administrative Class shares of the PIMCO
Total Return Fund in Japan, the Trust has adopted the following non-fundamental
operating policies (which may be changed without shareholder approval) with
respect to the PIMCO Total Return Fund.  These non-fundamental policies will
remain in effect only so long as (i) they are required in accordance with
standards of the

                                       39
<PAGE>

Japanese Securities Dealers Association and (ii) shares of the PIMCO Total
Return Fund are being offered in Japan.

(1)  The Trust will not sell shares of the PIMCO Total Return Fund in Japan
     except through PIMCO Funds Distributors LLC.

(2)  The Trust has appointed, and will maintain the appointment of, a bank or
     trust company as the place for safe-keeping of its assets in connection
     with the PIMCO Total Return Fund.

(3)  The Tokyo District Court shall have the jurisdiction over any and all
     litigation related to transactions in any class of shares of the PIMCO
     Total Return Fund acquired by Japanese investors as required by Article 26,
     Item 4 of the Rules Concerning Transactions of Foreign Securities of the
     Japan Securities Dealers Association.

(4)  The PIMCO Total Return Fund may not make short sales of securities or
     maintain a short position for the account of the Fund unless the total
     current value of the securities being the subject of short sales or of the
     short position is equal to or less than the net asset value of the PIMCO
     Total Return Fund.

(5)  The PIMCO Total Return Fund may not borrow money in excess of 10% of the
     value (taken at the lower of cost or current value) of its total assets
     (not including the amount borrowed) at the time the borrowing is made,
     except for extraordinary or emergency purposes, such as in the case of a
     merger, amalgamation or the like.

(6)  The PIMCO Total Return Fund may not acquire more than 50% of the
     outstanding voting securities of any issuer, if aggregated with the portion
     of holding in such securities by any and all other mutual funds managed by
     PIMCO.

(7)  The PIMCO Total Return Fund may not invest more than 15% of its total
     assets in voting securities privately placed, mortgage securities or
     unlisted voting securities which cannot be readily disposed of.  This
     restriction shall not be applicable to securities determined by PIMCO to be
     liquid and for which a market price (including a dealer quotation) is
     generally obtainable or determinable.

(8)  None of the portfolio securities of the PIMCO Total Return Fund may be
     purchased from or sold or loaned to any Trustee of the Trust, PIMCO, acting
     as investment adviser of the Trust, or any affiliate thereof or any of
     their directors, officers or employees, or any major shareholder thereof
     (meaning a shareholder who holds to the actual knowledge of PIMCO, on his
     own account whether in his own or other name (as well as a nominee's name),
     10% or more of the total issued outstanding shares of such a company)
     acting as principal or for their own account unless the transaction is made
     within the investment restrictions set forth in the Fund's prospectus and
     statement of additional information and either (i) at a price determined by
     current publicly available quotations (including a dealer quotation) or
     (ii) at competitive prices or interest rates prevailing from time to time
     on internationally recognized securities markets or internationally
     recognized money markets (including a dealer quotation).

     All percentage limitations on investments described in the restrictions
relating to the sale of shares in Japan will apply at the time of the making of
an investment and shall not be considered violated unless an excess or
deficiency occurs or exists immediately after and as a result of such
investment.  If

                                       40
<PAGE>

any violation of the foregoing investment restrictions occurs, the Trust will,
promptly after discovery of the violation, take such action as may be necessary
to cause the violation to cease, which shall be the only obligation of the Trust
and the only remedy in respect of the violation.

     If any of the foregoing standards shall, at any time when shares of the
PIMCO Total Return Fund are being offered for subscription by the Trust in Japan
or thereafter, no longer be required in accordance with the standards of the
Japanese Securities Dealers Association, then such standards shall no longer
apply.

Investment Adviser

    PIMCO serves as investment adviser to the Funds pursuant to an investment
advisory contract ("Advisory Contract") between PIMCO and the Trust.  PIMCO is a
subsidiary partnership of PIMCO Advisors. The general partners of PIMCO Advisors
are PIMCO Partners, G.P. and PIMCO Advisors Holdings L.P. ("PAH"). PIMCO
Partners, G.P. is a general partnership between PIMCO Holding LLC, a Delaware
limited liability company and an indirect wholly-owned subsidiary of Pacific
Life Insurance Company, and PIMCO Partners LLC, a California limited liability
company controlled by the current Managing Directors and two former Managing
Directors of PIMCO. PIMCO Partners, G.P. is the sole general partner of PAH.

    PIMCO is responsible for making investment decisions and placing orders for
the purchase and sale of the Trust's investments directly with the issuers or
with brokers or dealers selected by it in its discretion. See "Portfolio
Transactions."  PIMCO also furnishes to the Board of Trustees, which has

                                       45
<PAGE>

overall responsibility for the business and affairs of the Trust, periodic
reports on the investment performance of each Fund.

     On October 31, 1999, PIMCO Advisors, PAH and PIMCO Partners G.P., certain
of their affiliates, Allianz of America, Inc. ("Allianz of America") and certain
other parties named therein entered into an Implementation and Merger Agreement
(the "Merger Agreement") pursuant to which Allianz of America agreed to acquire
majority ownership of PIMCO Advisors and its subsidiaries, including PIMCO (the
"Transaction"). At the closing of the Transaction contemplated by the Merger
Agreement, Allianz of America will acquire approximately 70% of the outstanding
partnership interests in PIMCO Advisors, including the approximately 44%
interest held by PAH. Pacific Life Insurance Company ("Pacific Life"), which
through subsidiaries owns approximately a 30% interest in an indirect general
partner of PIMCO Advisors, will retain an indirect interest in PIMCO Advisors
following the closing of the Transaction. In connection with the Transaction,
Allianz of America will enter into a put/call arrangement for the possible
disposition of Pacific Life's indirect investment in PIMCO Advisors. The
Transaction is expected to be completed by the end of the first quarter of 2000,
although there is no assurance that the Transaction will be completed.

     Allianz AG, the parent of Allianz of America, is a publicly traded German
company which, together with its subsidiaries, comprises the world's second
largest insurance company as measured by premium income. Allianz AG is a leading
provider of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. The Allianz Group currently has assets under
management of more than $390 billion, and in its last fiscal year wrote
approximately $50 billion in gross insurance premiums. After consummation of the
Transaction, PIMCO and Allianz Group combined will have over $650 billion in
assets under management.

     Significant institutional shareholders of Allianz AG currently include
Dresdner Bank AG, Deutsche Bank AG, Munich Reinsurance and HypoVereinsbank.
Dresdner Bank AG and Deutsche Bank AG, as well as certain broker-dealers that
might be controlled by or affiliated with these entities, such as Bankers Trust
Company, BT Alex Brown, Inc., Deutsche Bank Securities, Inc. and Dresdner
Klienwort Benson North America LLC (collectively, the "Affiliated Brokers"), may
be considered to be affiliated persons of PIMCO. Once the Transaction is
consummated, absent an SEC exemption or other relief, the Funds generally would
be precluded from effecting principal transactions with the Affiliated Brokers,
and their ability to purchase securities being underwritten by an Affiliated
Broker or to utilize the Affiliated Brokers for agency transactions would be
subject to restrictions. PIMCO does not believe that the restrictions on
transactions with the Affiliated Brokers described above will materially
adversely affect its ability, post-closing, to provide services to the Funds,
the Funds' ability to take advantage of market opportunities, or the Funds'
overall performance.

     The consummation of the Transaction is subject to the approval of the
public unitholders of PAH, as well as to regulatory and client approvals, and
other conditions customary to transactions of this kind.

     This Statement of Additional Information will be supplemented or revised if
the Allianz Transaction does not occur substantially as set forth above.

     Under the terms of the Advisory Contract, PIMCO is obligated to manage the
Funds in accordance with applicable laws and regulations.  The investment
advisory services of PIMCO to the Trust are not exclusive under the terms of the
Advisory Contract.  PIMCO is free to, and does, render investment advisory
services to others.  The current Advisory Contract was approved by the Board of
Trustees, including a majority of the Trustees who are not parties to the
Advisory Contract or interested

                                       46
<PAGE>

persons of such parties ("Independent Trustees"), at a meeting held on November
22, 1994, as supplemented at meetings held on October 1, 1995, November 21,
1995, February 27, 1996, November 19, 1996, January 14, 1997, May 27, 1997,
February 24, 1998, August 25, 1998 and May 25, 1999, and was last approved by
the Trustees on August 24, 1999 and by shareholders of all then-operational
Funds on October 17, 1994.

     The Advisory Contract will continue in effect on a yearly basis provided
such continuance is approved annually (i) by the holders of a majority of the
outstanding voting securities of the Trust or by the Board of Trustees and (ii)
by a majority of the Independent Trustees. The Advisory Contract may be
terminated without penalty by vote of the Trustees or the shareholders of the
Trust, or by the Adviser, on 60 days' written notice by either party to the
contract and will terminate automatically if assigned.

     The Adviser currently receives a monthly investment advisory fee from each
Fund at an annual rate based on average daily net assets of the Funds as
follows:

Fund Administrator

  PIMCO also serves as Administrator to the Funds pursuant to an administration
agreement (the "Administration Agreement") with the Trust. PIMCO provides the
Funds with certain administrative and shareholder services necessary for Fund
operations and is responsible for the supervision of other Fund service
providers.  PIMCO may in turn use the facilities or assistance of its affiliates
to provide certain services under the Administration Agreement, on terms agreed
between PIMCO and such affiliates.  The administrative services provided by
PIMCO include but are not limited to: (1) shareholder servicing functions,
including preparation of shareholder reports and communications, (2) regulatory
compliance, such as reports and filings with the SEC and state securities
commissions, and (3) general supervision of the operations of the Funds,
including coordination of the services performed by the Funds' transfer agent,
custodian, legal counsel, independent accountants, and others.  PIMCO (or an
affiliate of PIMCO) also furnishes the Funds with office space facilities
required for conducting the business of the Funds, and pays the compensation of
those officers, employees and Trustees of the Trust affiliated with PIMCO.  In
addition, PIMCO, at its own expense, arranges for the provision of legal, audit,
custody, transfer agency and other services for the Funds, and is responsible
for the costs of registration of the Trust's shares and the printing of
prospectuses and shareholder reports for current shareholders. PIMCO has
contractually agreed to provide these services, and to bear these expenses, at
the following rates for each Fund (each expressed as a percentage of the Fund's
average daily net assets attributable to its classes of shares on an annual

*    As described below, the Administration Agreement includes a plan adopted
     under Rule 12b-1 which provides for the payment of up to .25% of the Class
     D Administrative Fee rate as reimbursement for expenses in respect of
     activities that may be deemed to be primarily intended to result in the
     sale of Class D shares.

     Except for the expenses paid by PIMCO, the Trust bears all costs of its
operations. The Funds are responsible for: (i) salaries and other compensation
of any of the Trust's executive officers and employees who are not officers,
directors, stockholders, or employees of PIMCO or its subsidiaries or
affiliates; (ii) taxes and governmental fees; (iii) brokerage fees and
commissions and other portfolio transaction expenses; (iv) costs of borrowing
money, including interest expenses; (v) fees and expenses of the Trustees who
are not "interested persons" of PIMCO or the Trust, and any counsel retained
exclusively for their benefit; (vi) extraordinary expenses, including costs of
litigation and indemnification expenses; (vii) expenses, such as organizational
expenses, which are capitalized in accordance with generally accepted accounting
principles; and (viii) any expenses allocated or allocable to a specific class
of shares ("Class-specific expenses").

     Class-specific expenses include distribution and service fees payable with
respect to different classes of shares and administrative fees as described
above, and may include certain other expenses as permitted by the Trust's
Amended and Restated Multi-Class Plan adopted pursuant to Rule 18f-3 under the
1940 Act and subject to review and approval by the Trustees.

     The Administration Agreement may be terminated by the Trustees, or by a
vote of a majority of the outstanding voting securities of the Trust, Fund, or
Class as applicable, at any time on 60 days' written notice. Following the
expiration of the one-year period commencing with the effectiveness of the
Administration Agreement, it may be terminated by PIMCO, also on 60 days'
written notice.

     The Administration Agreement is subject to annual approval by the Board,
including a majority of the Trust's Independent Trustees (as that term is
defined in the 1940 Act). The current Administration Agreement was approved by
the Board of Trustees, including all of the Independent Trustees at a meeting
held on February 24, 1998, as supplemented on August 25, 1998, February 23, 1999
and May 25, 1999. In approving the Administration Agreement, the Trustees
determined that: (1) the

                                       49
<PAGE>

Administration Agreement is in the best interests of the Funds and their
shareholders; (2) the services to be performed under the Agreement are services
required for the operation of the Funds; (3) PIMCO is able to provide, or to
procure, services for the Funds which are at least equal in nature and quality
to services that could be provided by others; and (4) the fees to be charged
pursuant to the Agreement are fair and reasonable in light of the usual and
customary charges made by others for services of the same nature and quality.

     Under the Administration Agreement, the Administrator or an affiliate may
pay financial service firms a portion of the Class D administration fees in
return for the firms' services (normally not to exceed an annual rate of .35% of
a Fund's average daily net assets attributable to Class D shares purchase
through such firms). The Administration Agreement includes a plan specific to
Class D shares that has been adopted in conformity with the requirements set
forth under Rule 12b-1 of the 1940 Act to allow for payment of up to .25% per
annum of the Class D administrative fees as reimbursement for expenses in
respect of activities that may be deemed to be primarily intended to result in
the sale of Class D shares. The principal types of activities for which such
payments may be made are services in connection with the distribution and
marketing of Class D shares and/or the provision of shareholder services. See
"Distribution of Trust Shares - Plan for Class D Shares."

     For the fiscal years ended March 31, 1999, 1998, and 1997, the aggregate
amount of the administration fees paid by each operational Fund was as follows:

                          DISTRIBUTION OF TRUST SHARES

Distributor and Multi-Class Plan

     PIMCO Funds Distributors LLC (the "Distributor") serves as the principal
underwriter of each class of the Trust's shares pursuant to a distribution
contract ("Distribution Contract") with the Trust which is subject to annual
approval by the Board. The Distributor is a wholly owned subsidiary of PIMCO
Advisors. The Distributor, located at 2187 Atlantic Street, Stamford,
Connecticut 06902, is a broker-dealer registered with the Securities and
Exchange Commission. The Distribution Contract is terminable with respect to a
Fund or class without penalty, at any time, by the Fund or class by not more
than 60 days' nor less than 30 days' written notice to the Distributor, or by
the Distributor upon not more than 60 days' nor less than 30 days' written
notice to the Trust. The Distributor is not obligated to sell any specific
amount of Trust shares.

     The Distribution Contract will continue in effect with respect to each Fund
and each class of shares thereof for successive one-year periods, provided that
each such continuance is specifically approved (i) by the vote of a majority of
the Trustees who are not interested persons of the Trust (as defined in the 1940
Act) and who have no direct or indirect financial interest in the Distribution
Contract, the Administration Agreement or the Distribution and/or Servicing
Plans described below; and (ii) by the vote of a majority of the entire Board of
Trustees cast in person at a meeting called for that purpose. If the
Distribution Contract is terminated (or not renewed) with respect to one or more
Funds or classes thereof, it may continue in effect with respect to any class of
any Fund as to which it has not been terminated (or has been renewed).

     The Trust offers eight classes of shares: Class A, Class B, Class C, Class
D, Class J, Class K, the Institutional Class and the Administrative Class. Class
J and Class K shares are offered only to non-U.S. investors outside the United
States.

     Class A, Class B and Class C shares of the Trust are offered through firms
("participating brokers") which are members of the National Association of
Securities Dealers, Inc. ("NASD"), and which have dealer agreements with the
Distributor, or which have agreed to act as introducing brokers for the
Distributor ("introducing brokers").

     Class D shares are generally offered to clients of financial service firms,
such as broker-dealers or registered investment advisors, with which the
Distributor has an agreement for the use of PIMCO Funds: Pacific Investment
Management Series in particular investment products, programs or accounts for
which a fee may be charged.

     Institutional Class shares are offered primarily for direct investment by
investors such as pension and profit sharing plans, employee benefit trusts,
endowments, foundations, corporations and high net worth individuals.
(Institutional Class shares may also be offered through certain financial
intermediaries that charge their customers transaction or other fees with
respect to the customer's investment in the Funds.) Administrative Class shares
are offered primarily through employee benefit plans alliances, broker-dealers,
and other intermediaries, and each Fund pays service or distribution fees to
such entities for services they provide to Administrative Class shareholders.

                                       51
<PAGE>

     Class J and Class K shares are offered through foreign broker dealers,
banks and other financial institutions. Class J and Class K shares are offered
to non-U.S. investors as well as though various non-U.S. investment products,
programs or accounts for which a fee may be charged by investment intermediaries
in addition to those described in the Prospectus and SAI.

     The Trust has adopted an Amended and Restated Multi-Class Plan
("Multi-Class Plan") pursuant to Rule 18f-3 under the 1940 Act. Under the
Multi-Class Plan, shares of each class of each Fund represent an equal pro rata
interest in such Fund and, generally, have identical voting, dividend,
liquidation, and other rights, preferences, powers, restrictions, limitations,
qualifications and terms and conditions, except that: (a) each class has a
different designation; (b) each class of shares bears any class-specific
expenses allocated to it; and (c) each class has exclusive voting rights on any
matter submitted to shareholders that relates solely to its distribution or
service arrangements, and each class has separate voting rights on any matter
submitted to shareholders in which the interests of one class differ from the
interests of any other class.

     Each class of shares bears any class specific expenses allocated to such
class, such as expenses related to the distribution and/or shareholder servicing
of such class. In addition, each class may, at the Trustees' discretion, also
pay a different share of other expenses, not including advisory or custodial
fees or other expenses related to the management of the Trust's assets, if these
expenses are actually incurred in a different amount by that class, or if the
class receives services of a different kind or to a different degree than the
other classes. All other expenses are allocated to each class on the basis of
the net asset value of that class in relation to the net asset value of the
particular Fund. In addition, each class may have a differing sales charge
structure, and differing exchange and conversion features.

Contingent Deferred Sales Charge and Initial Sales Charge

     As described in the Class A, B and C Prospectus under the caption
"Investment Options (Class A, B and C Shares)," a contingent deferred sales
charge is imposed upon certain redemptions of the Class A, Class B and Class C
shares. No contingent deferred sales charge is currently imposed upon
redemptions of Class D, Institutional Class or Administrative Class shares.
Because contingent deferred sales charges are calculated on a Fund-by-Fund
basis, shareholders should consider whether to exchange shares of one Fund for
shares of another Fund prior to redeeming an investment if such an exchange
would reduce the contingent deferred sales charge applicable to such
redemptions.

     During the fiscal years ended March 31, 1999, March 31, 1998 and March 31,
1997, the Distributor received the following aggregate amounts in contingent
deferred sales charges on Class A shares, Class B shares and Class C shares of
the Funds:

<TABLE>
<CAPTION>
                                    Year Ended 3/31/99   Year Ended 3/31/98   Year Ended 3/31/97

 Class A                                  $37,142              $37,724                $670
 Class B                               $1,653,443             $694,715             $85,380
 Class C                                 $543,223             $246,969             $44,409
</TABLE>

     In certain cases described in the Class A, B and C Prospectus, the
contingent deferred sales charge is waived on redemptions of Class A, Class B or
Class C shares for certain classes of individuals or entities on account of (i)
the fact that the Trust's sales-related expenses are lower for certain of such
classes than for classes for which the contingent deferred sales charge is not
waived, (ii) waiver of the contingent deferred sales charge with respect to
certain of such classes is consistent with certain Internal Revenue Code
policies concerning the favored tax treatment of accumulations, and (iii) with
respect to certain of such classes, considerations of fairness, and competitive
and administrative factors.

     As described in the Class A, B and C Prospectus under the caption
"Investment Options (Class A, B and C Shares)," Class A shares of the Trust
(except with respect to the Money Market Fund) are

                                       52
<PAGE>

sold pursuant to an initial sales charge, which declines as the amount of
purchase reaches certain defined levels. For the fiscal years ended March 31,
1999, March 31, 1998, and March 31, 1997, the Distributor received an aggregate
of $6,227,864, $2,598,104 and $389,133, respectively, and retained $750,751,
$186,443 and $45,871, respectively, in initial sales charges paid by Class A
shareholders of the Trust.

Distribution and Servicing Plans for Class A, Class B and Class C Shares

     As stated in the text of the Class A, B and C Prospectus under the caption
"Management of the Trust--Distribution and Servicing (12b-1) Plans," Class A,
Class B and Class C shares of the Trust are continuously offered through
participating brokers which are members of the NASD and which have dealer
agreements with the Distributor, or which have agreed to act as introducing
brokers.

     Pursuant to separate Distribution and Servicing Plans for Class A, Class B
and Class C shares (the "Retail Plans"), as described in the Class A, B and C
Prospectus, in connection with the distribution of Class B and Class C shares of
the Trust, the Distributor receives certain distribution fees from the Trust,
and in connection with personal services rendered to Class A, Class B and Class
C shareholders of the Trust and the maintenance of shareholder accounts, the
Distributor receives certain servicing fees from the Trust. Subject to the
percentage limitations on these distribution and servicing fees set forth below,
the distribution and servicing fees may be paid with respect to services
rendered and expenses borne in the past with respect to Class A, Class B and
Class C shares as to which no distribution and servicing fees were paid on
account of such limitations. As described in the Class A, B and C Prospectus,
the Distributor pays (i) all or a portion of the distribution fees it receives
from the Trust to participating and introducing brokers, and (ii) all or a
portion of the servicing fees it receives from the Trust to participating and
introducing brokers, certain banks and other financial intermediaries.

     The Distributor makes distribution and servicing payments to participating
brokers and servicing payments to certain banks and other financial
intermediaries in connection with the sale of Class B and Class C shares and
servicing payments to participating brokers, certain banks and other financial
intermediaries in connection with the sale of Class A shares. In the case of
Class A shares, these parties are also compensated based on the amount of the
front-end sales charge reallowed by the Distributor, except in cases where Class
A shares are sold without a front-end sales charge (although the Distributor may
pay brokers additional compensation in connection with sales of Class A shares
without a sales charge). In the case of Class B shares, participating brokers
and other financial intermediaries are compensated by an advance of a sales
commission by the Distributor. In the case of Class C shares, part or all of the
first year's distribution and servicing fee is generally paid at the time of
sale. Pursuant to a Distribution Contract with the Trust, with respect to each
Fund's Class A, Class B and Class C shares, the Distributor bears various other
promotional and sales related expenses, including the cost of printing and
mailing prospectuses to persons other than current shareholders.

     The Retail Plans were adopted pursuant to Rule 12b-l under the 1940 Act and
are of the type known as "compensation" plans. This means that, although the
Trustees of the Trust are expected to take into account the expenses of the
Distributor and its predecessors in their periodic review of the Retail Plans,
the fees are payable to compensate the Distributor for services rendered even if
the amount paid exceeds the Distributor's expenses.

     The distribution fee applicable to Class B and Class C shares may be spent
by the Distributor on any activities or expenses primarily intended to result in
the sale of Class B or Class C shares, respectively, including compensation to,
and expenses (including overhead and telephone expenses) of, financial
consultants or other employees of the Distributor or of participating or
introducing brokers who engage in distribution of Class B or Class C shares,
printing of prospectuses and reports for other than existing Class B or Class C
shareholders, advertising, and preparation, printing and distribution of sales
literature. The servicing fee, applicable to Class A, Class B and Class C shares
of the Trust, may be spent by the Distributor on personal services rendered to
shareholders of the Trust and the maintenance of shareholder accounts, including
compensation to, and expenses (including telephone and overhead

                                       53
<PAGE>

expenses) of, financial consultants or other employees of participating or
introducing brokers, certain banks and other financial intermediaries who aid in
the processing of purchase or redemption requests or the processing of dividend
payments, who provide information periodically to shareholders showing their
positions in a Fund's shares, who forward communications from the Trust to
shareholders, who render ongoing advice concerning the suitability of particular
investment opportunities offered by the Trust in light of the shareholders'
needs, who respond to inquiries from shareholders relating to such services, or
who train personnel in the provision of such services. Distribution and
servicing fees may also be spent on interest relating to unreimbursed
distribution or servicing expenses from prior years.

     Many of the Distributor's sales and servicing efforts involve the Trust as
a whole, so that fees paid by Class A, Class B or Class C shares of any Fund may
indirectly support sales and servicing efforts relating to the other Funds'
shares of the same class. In reporting its expenses to the Trustees, the
Distributor itemizes expenses that relate to the distribution and/or servicing
of a single Fund's shares, and allocates other expenses among the Funds based on
their relative net assets. Expenses allocated to each Fund are further allocated
among its classes of shares annually based on the relative sales of each class,
except for any expenses that relate only to the sale or servicing of a single
class. The Distributor may make payments to brokers (and with respect to
servicing fees only, to certain banks and other financial intermediaries) of up
to the following percentages annually of the average daily net assets
attributable to shares in the accounts of their customers or clients:

1.   Applies, in part, to Class A, Class B and Class C shares of the Trust
     issued to former shareholders of PIMCO Advisors Funds in connection with
     the reorganizations/mergers of series of PIMCO Advisors Funds as/with Funds
     of the Trust in a transaction which took place on January 17, 1997.
2.   Payable only with respect to shares outstanding for one year or more. 3.
     Payable only with respect to shares outstanding for one year or more except
     in the case of shares for which no payment is made to the party at the time
     of sale.

     The Distributor may from time to time pay additional cash bonuses or other
incentives to selected participating brokers in connection with the sale or
servicing of Class A, Class B and Class C shares of the Funds. On some
occasions, such bonuses or incentives may be conditioned upon the sale of a
specified minimum dollar amount of the shares of a Fund and/or all of the Funds
together or a particular class of shares, during a specific period of time. The
Distributor currently expects that such additional bonuses or incentives will
not exceed .50% of the amount of any sale. Pacific Investment Management (in its
capacity as administrator) may also pay participating brokers and other
intermediaries for sub-transfer agency and other services.

     If in any year the Distributor's expenses incurred in connection with the
distribution of Class B and Class C shares and, for Class A, Class B and Class C
shares, in connection with the servicing of shareholders and the maintenance of
shareholder accounts, exceed the distribution and/or servicing fees paid by the
Trust, the Distributor would recover such excess only if the Retail Plan with
respect to such class of shares continues to be in effect in some later year
when the distribution and/or servicing fees exceed the Distributor's expenses.
The Trust is not obligated to repay any unreimbursed expenses that may exist at
such time, if any, as the relevant Retail Plan terminates.

  Each Retail Plan may be terminated with respect to any Fund to which the Plan
relates by vote of a majority of the Trustees who are not interested persons of
the Trust (as defined in the 1940 Act) and who have no direct or indirect
financial interest in the operation of the Plan or the Distribution Contract
("Disinterested Trustees") or by vote of a majority of the outstanding voting
securities of the relevant class of that Fund. Any change in any Retail Plan
that would materially increase the cost to the class of shares of any Fund to
which the Plan relates requires approval by the affected class of shareholders
of that Fund. The Trustees review quarterly written reports of such costs and
the purposes for which such costs have been incurred. Each Retail Plan may be
amended by vote of the Disinterested Trustees cast in person at a meeting called
for the purpose. As long as the Retail Plans are in effect, selection and
nomination of those Trustees who are not interested persons of the Trust shall
be committed to the discretion of such Disinterested Trustees.

  The Retail Plans will continue in effect with respect to each Fund and each
class of shares thereof for successive one-year periods, provided that each such
continuance is specifically approved (i) by the vote of a majority of the
Disinterested Trustees and (ii) by the vote of a majority of the entire Board of
Trustees cast in person at a meeting called for that purpose.

  The Retail Plans went into effect for the Trust in January 1997. If a Retail
Plan is terminated (or not renewed) with respect to one or more Funds, it may
continue in effect with respect to any class of any Fund as to which it has not
been terminated (or has been renewed).

     The Trustees believe that the Retail Plans will provide benefits to the
Trust. The Trustees believe that the Retail Plans will result in greater sales
and/or fewer redemptions of Trust shares, although it is impossible to know for
certain the level of sales and redemptions of Trust shares that would occur in
the absence of the Retail Plans or under alternative distribution schemes.
Although the Funds' expenses are essentially fixed, the Trustees believe that
the effect of the Retail Plans on sales and/or redemptions may benefit the Trust
by reducing Fund expense ratios and/or by affording greater flexibility to
Portfolio Managers. From time to time, expenses of the Distributor incurred in
connection with the sale of Class B and Class C shares of the Funds, and in
connection with the servicing of Class B and Class C shareholders of the Funds
and the maintenance of shareholder accounts, may exceed the distribution and
servicing fees collected by the Distributor. The Trustees consider such
unreimbursed amounts, among other factors, in determining whether to cause the
Funds to continue payments of distribution and servicing fees in the future with
respect to Class B and Class C shares.

Class shares of each Fund, in an amount up to 0.25% on an annual basis of the
average daily net assets of that class, financial intermediaries for costs and
expenses incurred in connection with the distribution and marketing of
Administrative Class shares and/or the provision of certain shareholder services
to its customers that invest in Administrative Class shares of the Funds.  Such
services may include, but are not limited to, the following: providing
facilities to answer questions from prospective investors about a Fund;
receiving and answering correspondence, including requests for prospectuses and
statements of additional information; preparing, printing and delivering
prospectuses and shareholder reports to prospective shareholders; complying with
federal and state securities laws pertaining to the sale of Administrative Class
shares; and assisting investors in completing application forms and selecting
dividend and other account options.

     Under the terms of the Administrative Services Plan, the Trust is permitted
to reimburse, out of the assets attributable to the Administrative Class shares
of each Fund, in an amount up to 0.25% on an annual basis of the average daily
net assets of that class, financial intermediaries that provide certain
administrative services for Administrative Class shareholders.  Such services
may include, but are not limited to, the following functions:  receiving,
aggregating and processing shareholder orders; furnishing shareholder sub-
accounting; providing and maintaining elective shareholder services such as
check writing and wire transfer services; providing and maintaining pre-
authorized investment plans;

                                       59
<PAGE>

communicating periodically with shareholders; acting as the sole shareholder of
record and nominee for shareholders; maintaining accounting records for
shareholders; answering questions and handling correspondence from shareholders
about their accounts; and performing similar account administrative services.

     The same entity may be the recipient of fees under both the Administrative
Class Distribution Plan and the Administrative Services Plan, but may not
receive fees under both plans with respect to the same assets.  Fees paid
pursuant to either Plan may be paid for shareholder services and the maintenance
of shareholder accounts, and therefore may constitute "service fees" for
purposes of applicable rules of the National Association of Securities Dealers,
Inc.  Each Plan has been adopted in accordance with the requirements of Rule
12b-1 under the 1940 Act and will be administered in accordance with the
provisions of that rule, except that shareholders will not have the voting
rights set forth in Rule 12b-1 with respect to the Administrative Services Plan
that they will have with respect to the Administrative Distribution Plan.

     Each Administrative Plan provides that it may not be amended to materially
increase the costs which Administrative Class shareholders may bear under the
Plan without the approval of a majority of the outstanding voting securities of
the Administrative Class, and by vote of a majority of both (i) the Trustees of
the Trust and (ii) those Trustees who are not "interested persons" of the Trust
(as defined in the 1940 Act) and who have no direct or indirect financial
interest in the operation of the Plan or any agreements related to it (the "Plan
Trustees"), cast in person at a meeting called for the purpose of voting on the
Plan and any related amendments.

     Each Administrative Plan provides that it may not take effect until
approved by vote of a majority of both (i) the Trustees of the Trust and (ii)
the disinterested Trustees defined above.  The Administrative Class Distribution
Plan further provides that it may not take effect unless approved by the vote of
a majority of the outstanding voting securities of the Administrative Class.

     Each Administrative Plan provides that it shall continue in effect so long
as such continuance is specifically approved at least annually by the Trustees
and the disinterested Trustees defined above.  Each Administrative Plan provides
that any person authorized to direct the disposition of monies paid or payable
by a class pursuant to the Plan or any related agreement shall provide to the
Trustees, and the Board shall review at least quarterly, a written report of the
amounts so expended and the purposes for which such expenditures were made.

     Each Administrative Plan is a "reimbursement plan," which means that fees
are payable to the relevant financial intermediary only to the extent necessary
to reimburse expenses incurred pursuant to such plan.  Each Administrative Plan
provides that expenses payable under the Plan may be carried forward for
reimbursement for up to twelve months beyond the date in which the expense is
incurred, subject to the limit that not more that 0.25% of the average daily net
assets of Administrative Class shares may be used in any month to pay expenses
under the Plan.  Each Plan requires that Administrative Class shares incur no
interest or carrying charges.

     Rules of the NASD limit the amount of distribution fees that may be paid by
mutual funds.  "Service fees," defined to mean fees paid for providing
shareholder services or the maintenance of accounts (but not transfer agency
services) are not subject to the limits.  The Trust believes that some, if not
all, of the fees paid pursuant to both Administrative Plans will qualify as
"service fees" and therefore will not be limited by NASD rules.

     Institutional and Administrative Class shares of the Trust may also be
offered through certain brokers and financial intermediaries ("service agents")
that have established a shareholder servicing relationship with the Trust on
behalf of their customers.  The Trust pays no compensation to such entities
other than service fees paid with respect to Administrative Class shares.
Service agents may impose additional or different conditions than the Trust on
the purchase, redemption or exchanges of Trust

                                       60
<PAGE>

shares by their customers. Service agents may also independently establish and
charge their customers transaction fees, account fees and other amounts in
connection which purchases, sales and redemption of Trust shares in addition to
any fees charged by the Trust. Each service agent is responsible for
transmitting to its customers a schedule of any such fees and information
regarding any additional or different conditions regarding purchases and
redemptions. Shareholders who are customers of service agents should consult
their service agents for information regarding these fees and conditions.

Payments Pursuant to the Administrative Plans

     For the fiscal years ended March 31, 1999, March 31, 1998 and March 31,
1997 the Trust paid qualified service providers an aggregate amount of
$3,691,083, $850,407 and $301,019, respectively, pursuant to the Administrative
Services Plan and the Administrative Distribution Plan.  Such payments were
allocated among the Funds listed below as follows:

Plan for Class D Shares


     As described under "Management of the Trust- Fund Administrator," the
Funds' Administration Agreement includes a plan (the "Class D Plan") adopted
pursuant to Rule 12b-1 under the 1940 Act which provides for the payment of up
to .25% of the Class D administrative fees as reimbursement for expenses in
respect of activities that may be deemed to be primarily intended to result in
the sale of Class D shares.

     Specifically, the Administration Agreement provides that the Administrator
shall provide in respect of Class D shares (either directly or by procuring
through other entities, including various financial services firms such as
broker-dealers and registered investment advisors ("Service Organizations"))
some or all of the following services and facilities in connection with direct
purchases by shareholders or in connection with products, programs or accounts
offered by such Service Organizations ("Special Class D Services"): (i)
facilities for placing orders directly for the purchase of a Fund's shares and
tendering a Fund's Class D shares for redemption; (ii) advertising with respect
to a Fund's Class D shares; (iii) providing information about the Funds; (iv)
providing facilities to answer questions from prospective investors about the
Funds; (v) receiving and answering correspondence, including requests for
prospectuses and statements of additional information; (vi) preparing, printing
and delivering prospectuses and shareholder reports to prospective shareholders;
(vii) assisting investors in

                                       61
<PAGE>

applying to purchase Class D shares and selecting dividend and other account
options; and (viii) shareholder services provided by a Service Organization that
may include, but are not limited to, the following functions: receiving,
aggregating and processing shareholder orders; furnishing shareholder sub-
accounting; providing and maintaining elective shareholder services such as
check writing and wire transfer services; providing and maintaining pre-
authorized investment plans; communicating periodically with shareholders;
acting as the sole shareholder of record and nominee for shareholders;
maintaining accounting records for shareholders; answering questions and
handling correspondence from shareholders about their accounts; issuing
confirmations for transactions by shareholders; performing similar account
administrative services; providing such shareholder communications and
recordkeeping services as may be required for any program for which the Service
Organization is a sponsor that relies on Rule 3a-4 under the 1940 Act; and
providing such other similar services as may reasonably be requested to the
extent the Service Organization is permitted to do so under applicable statutes,
rules, or regulations.

     The Administrator has entered into an agreement with the Distributor under
which the distributor is compensated for providing or procuring certain of the
Class D Services at the rate of .25% per annum of all assets attributable to
Class D shares sold through the Distributor.

     The Trust and the Administrator understand that some or all of the Special
Class D Services pursuant to the Administration Agreement may be deemed to
represent services primarily intended to result in the sale of Class D shares.
The Administration Agreement includes the Class D Plan to account for this
possibility.  The Administration Agreement provides that any portion of the fees
paid thereunder in respect of Class D shares representing reimbursement for the
Administrator's and the Distributor's expenditures and internally allocated
expenses in respect of Class D Services of any Fund shall not exceed the rate of
 .25% per annum of the average daily net assets of such Fund attributable to
Class D shares.

     In accordance with Rule 12b-1 under the 1940 Act, the Class D Plan may not
be amended to increase materially the costs which Class D shareholders may bear
under the Plan without approval of a majority of the outstanding Class D shares,
and by vote of a majority of both (i) the Trustees of the Trust and (ii) those
Trustees ("disinterested Class D Plan Trustees") who are not "interested
persons" of the Trust (as defined in the 1940 Act) and who have no direct or
indirect financial interest in the operation of the Plan or any agreements
related to it, cast in person at a meeting called for the purpose of voting on
the Plan and any related amendments.  The Class D Plan may not take effect until
approved by a vote of a majority of both (i) the Trustees of the Trust and (ii)
the disinterested Class D Plan Trustees.  In addition, the Class D Plan may not
take effect unless it is approved by the vote of a majority of the outstanding
Class D shares and it shall continue in effect so long as such continuance is
specifically approved at least annually by the Trustees and the disinterested
Class D Plan Trustees.

     With respect to the Class D Plan, the Administration Agreement requires the
Administrator to present reports as to out-of-pocket expenditures and internal
expenses allocations of the Administrator and the Distributor at least quarterly
and in a manner that permits the disinterested Class D Plan Trustees to
determine that portion of the Class D administrative fees paid thereunder which
represents reimbursements in respect of Special Class D Services.

     Rules of the NASD limit the amount of distribution fees that may be paid by
mutual funds.  "Service fees," defined to mean fees paid for providing
shareholder services or the maintenance of accounts (but not transfer agency
services) are not subject to the limits.  The Trust believes that most, if not
all, of the fees paid pursuant to the Class D Plan will qualify as "service
fees" and therefore will not be limited by NASD rules.

Distribution and Servicing Plan for Class J and Class K Shares


     Class J and Class K each has a separate distribution and servicing plan
(the "Class J-K Plans").  Distribution fees paid pursuant to the Class J-K Plans
may only be paid in connection with services provided with respect to Class J
and Class K shares.

     As stated in the Prospectus relating to Class J and Class K shares under
the caption "Service and Distribution Fees," the Distributor pays (i) all or a
portion of the distribution fees it receives from the Trust to participating and
introducing brokers, and (ii) all or a portion of the servicing fees it receives
from the Trust to participating and introducing brokers, certain banks and other
financial intermediaries.

     Each Class J-K Plan may be terminated with respect to any Fund to which the
Class J-K Plan relates by vote of a majority of the Trustees who are not
interested persons of the Trust (as defined in the 1940 Act) and who have no
direct or indirect financial interest in the operation of the Plan or the
Distribution Contract ("Disinterested Trustees") or by vote of a majority of the
outstanding voting securities of the relevant class of that Fund. Pursuant to
Rule 12b-1, any change in either Class J-K Plan that would materially increase
the cost to the class of shares of any Fund to which the Plan relates requires
approval by the affected class of shareholders of that Fund. The Trustees review
quarterly written reports of such costs and the purposes for which such costs
have been incurred.  Each Class J-K Plan may be amended by vote of the
Disinterested Trustees cast in person at a meeting called for the purpose. As
long as the Class J-K Plans are in effect, selection and nomination of those
Trustees who are not interested persons of the Trust shall be committed to the
discretion of such Disinterested Trustees.

     The Class J-K Plans will continue in effect with respect to each Fund and
each class of shares thereof for successive one-year periods, provided that each
such continuance is specifically approved (i) by the vote of a majority of the
Disinterested Trustees and (ii) by the vote of a majority of the entire Board of
Trustees cast in person at a meeting called for that purpose.

     If a Class J-K Plan is terminated (or not renewed) with respect to one or
more Funds, it may continue in effect with respect to any class of any Fund as
to which it has not been terminated (or has been renewed).

     The Trustees believe that the Class J-K Plans will provide benefits to the
Trust. The Trustees believe that the Class J-K Plans will result in greater
sales and/or fewer redemptions of Trust shares, although it is impossible to
know for certain the level of sales and redemptions of Trust shares that would
occur in the absence of the Class J-K Plans or under alternative distribution
schemes. Although the

                                       63
<PAGE>

Funds' expenses are essentially fixed, the Trustees believe that the effect of
the Class J-K Plans on sales and/or redemptions may benefit the Trust by
reducing Fund expense ratios and/or by affording greater flexibility to
Portfolio Managers. From time to time, expenses of the Distributor incurred in
connection with the sale of Class J and Class K shares of the Funds, and in
connection with the servicing of Class J and Class K shareholders of the Funds
and the maintenance of shareholder accounts, may exceed the distribution and
servicing fees collected by the Distributor. The Trustees consider such
unreimbursed amounts, among other factors, in determining whether to cause the
Funds to continue payments of distribution and servicing fees in the future with
respect to Class J and Class K shares.

Purchases, Exchanges and Redemptions

     Purchases, exchanges and redemptions of Class A, Class B, Class C and Class
D shares are discussed in the Class A, B and C and Class D Prospectuses under
the headings "How to Buy Shares," "Exchange Privilege," and "How to Redeem," and
that information is incorporated herein by reference.  Purchases, exchanges and
redemptions of Institutional and Administrative Class shares and Class J and
Class K shares are discussed in the Institutional Prospectus under the headings
"Purchase of Shares," "Redemption of Shares," and "Net Asset Value," and in the
Class J and Class K supplement thereto, and that information is incorporated
herein by reference.

     Certain managed account clients of the Adviser may purchase shares of the
Trust.  To avoid the imposition of duplicative fees, the Adviser may be required
to make adjustments in the management fees charged separately by the Adviser to
these clients to offset the generally higher level of management fees and
expenses resulting from a client's investment in the Trust.

     Certain clients of the Adviser whose assets would be eligible for purchase
by one or more of the Funds may purchase shares of the Trust with such assets.
Assets so purchased by a Fund will be valued in accordance with procedures
adopted by the Board of Trustees.

     Certain shares of the Funds are not qualified or registered for sale in all
states and Class J and Class K shares are not qualified or registered for sale
in the United States.  Prospective investors should inquire as to whether shares
of a particular Fund or class are available for offer and sale in their state of
domicile or residence.  Shares of a Fund may not be offered or sold in any state
unless registered or qualified in that jurisdiction, unless an exemption from
registration or qualification is available.

     Independent financial intermediaries unaffiliated with PIMCO may perform
shareholder servicing functions with respect to certain of their clients whose
assets may be invested in the Funds. These services, normally provided by PIMCO
directly to Trust shareholders, may include the provision of ongoing information
concerning the Funds and their investment performance, responding to shareholder
inquiries, assisting with purchases, redemptions and exchanges of Trust shares,
and other services. PIMCO may pay fees to such entities for the provision of
these services which PIMCO normally would perform, out of PIMCO's own resources.

     As described in the Class A, B and C and Class D Prospectuses under the
caption "Exchanging Shares," and in the Institutional Prospectus under the
caption "Exchange Privilege," a shareholder may exchange shares of any Fund for
shares of any other Fund of the Trust (except the PIMCO International Fund and
the PIMCO Emerging Markets Bond Fund II, each of which is only available to
private account clients of PIMCO) or any  series of PIMCO Funds:  Multi-Manager
Series, within the same class on the basis of their respective net asset values.
The original purchase date(s) of shares exchanged for purposes of calculating
any contingent deferred sales charge will carry over to the investment in the
new Fund. For example, if a shareholder invests in the Class C shares of one
Fund and 6 months later (when the contingent deferred sales charge upon
redemption would normally be 1%) exchanges his shares for Class C shares of
another Fund, no sales charge would be imposed upon the exchange but the
investment in the other Fund would be subject to the 1% contingent deferred
sales charge until one year after the date of the shareholder's investment in
the first Fund as described in the Class A, B and C Prospectus

                                       64
<PAGE>

under "Alternative Purchase Arrangements." With respect to Class B or Class C
shares, or Class A shares subject to a contingent deferred sales charge, if less
than all of an investment is exchanged out of a Fund, any portion of the
investment attributable to capital appreciation and/or reinvested dividends or
capital gains distributions will be exchanged first, and thereafter any portions
exchanged will be from the earliest investment made in the Fund from which the
exchange was made.

     Orders for exchanges accepted prior to the close of regular trading on the
New York Stock Exchange on any day the Trust is open for business will be
executed at the respective net asset values determined as of the close of
business that day. Orders for exchanges received after the close of regular
trading on the Exchange on any business day will be executed at the respective
net asset values determined at the close of the next business day.

     An excessive number of exchanges may be disadvantageous to the Trust.
Therefore, the Trust, in addition to its right to reject any exchange, reserves
the right to adopt a policy of terminating the exchange privilege of any
shareholder who makes more than a specified number of exchanges in a 12-month
period or in any calendar quarter.  The Trust reserves the right to modify or
discontinue the exchange privilege at any time.

     The Trust reserves the right to suspend or postpone redemptions during any
period when: (a) trading on the New York Stock Exchange is restricted, as
determined by the SEC, or that Exchange is closed for other than customary
weekend and holiday closings; (b) the SEC has by order permitted such
suspension; or (c) an emergency, as determined by the SEC, exists, making
disposal of portfolio securities or valuation of net assets of the Fund not
reasonably practicable.

     The Trust is committed to paying in cash all requests for redemptions by
any shareholder of record of the Funds, limited in amount with respect to each
shareholder during any 90-day period to the lesser of (i) $250,000, or (ii) 1%
of the net asset value of the Trust at the beginning of such period. Although
the Trust will normally redeem all shares for cash, it may, in unusual
circumstances, redeem amounts in excess of the lesser of (i) or (ii) above by
payment in kind of securities held in the Funds' portfolios.

     Due to the relatively high cost of maintaining smaller accounts, the Trust
reserves the right to redeem shares in any account for their then-current value
(which will be promptly paid to the investor) if at any time, due to shareholder
redemption, the shares in the account do not have a value of at least a
specified amount, the minimums of which are currently set at $250 for Class A,
Class B and Class C shares, $2,000 for Class D shares, and $100,000 for
Institutional Class and Administrative Class shares ($10,000 with respect to
Institutional Class and Administrative Class accounts opened before January 1,
1995).  The Prospectuses may set higher minimum account balances for one or more
classes from time to time depending upon the Trust's current policy.  An
investor will be notified that the value of his account is less than the minimum
and allowed at least 30 days to bring the value of the account up to at least
the specified amount before the redemption is processed.  The Declaration of
Trust also authorizes the Trust to redeem shares under certain other
circumstances as may be specified by the Board of Trustees.  The Trust may also
charge periodic account fees for accounts that fall below minimum balances, as
described in the Prospectuses.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

Investment Decisions and Portfolio Transactions

     Investment decisions for the Trust and for the other investment advisory
clients of the Adviser are made with a view to achieving their respective
investment objectives.  Investment decisions are the product of many factors in
addition to basic suitability for the particular client involved (including the
Trust).  Some securities considered for investments by the Funds may also be
appropriate for other clients served by the Adviser.  Thus, a particular
security may be bought or sold for certain clients even

                                       65
<PAGE>

though it could have been bought or sold for other clients at the same time. If
a purchase or sale of securities consistent with the investment policies of a
Fund and one or more of these clients served by the Adviser is considered at or
about the same time, transactions in such securities will be allocated among the
Fund and clients in a manner deemed fair and reasonable by the Adviser. The
Adviser may aggregate orders for the Funds with simultaneous transactions
entered into on behalf of other clients of the Adviser so long as price and
transaction expenses are averaged either for that transaction or for the day.
Likewise, a particular security may be bought for one or more clients when one
or more clients are selling the security. In some instances, one client may sell
a particular security to another client. It also sometimes happens that two or
more clients simultaneously purchase or sell the same security, in which event
each day's transactions in such security are, insofar as possible, averaged as
to price and allocated between such clients in a manner which in the Adviser's
opinion is equitable to each and in accordance with the amount being purchased
or sold by each. There may be circumstances when purchases or sales of portfolio
securities for one or more clients will have an adverse effect on other clients.

Brokerage and Research Services

     There is generally no stated commission in the case of fixed income
securities, which are traded in the over-the-counter markets, but the price paid
by the Trust usually includes an undisclosed dealer commission or mark-up.  In
underwritten offerings, the price paid by the Trust includes a disclosed, fixed
commission or discount retained by the underwriter or dealer.  Transactions on
U.S. stock exchanges and other agency transactions involve the payment by the
Trust of negotiated brokerage commissions.  Such commissions vary among
different brokers.  Also, a particular broker may charge different commissions
according to such factors as the difficulty and size of the transaction.
Transactions in foreign securities generally involve the payment of fixed
brokerage commissions, which are generally higher than those in the United
States.

     The Adviser places all orders for the purchase and sale of portfolio
securities, options and futures contracts for the relevant Fund and buys and
sells such securities, options and futures for the Trust through a substantial
number of brokers and dealers.  In so doing, the Adviser uses its best efforts
to obtain for the Trust the most favorable price and execution available, except
to the extent it may be permitted to pay higher brokerage commissions as
described below.  In seeking the most favorable price and execution, the
Adviser, having in mind the Trust's best interests, considers all factors it
deems relevant, including, by way of illustration, price, the size of the
transaction, the nature of the market for the security, the amount of the
commission, the timing of the transaction taking into account market prices and
trends, the reputation, experience and financial stability of the broker-dealer
involved and the quality of service rendered by the broker-dealer in other
transactions.

     The Adviser places orders for the purchase and sale of portfolio
investments for the Funds' accounts with brokers or dealers selected by it in
its discretion. In effecting purchases and sales of portfolio securities for the
account of the Funds, the Adviser will seek the best price and execution of the
Funds' orders. In doing so, a Fund may pay higher commission rates than the
lowest available when the Adviser believes it is reasonable to do so in light of
the value of the brokerage and research services provided by the broker
effecting the transaction, as discussed below.  The Adviser also may consider
sales of shares of the Trust as a factor in the selection of broker-dealers to
execute portfolio transactions for the Trust.

     It has for many years been a common practice in the investment advisory
business for advisers of investment companies and other institutional investors
to receive research services from broker-dealers which execute portfolio
transactions for the clients of such advisers.  Consistent with this practice,
the Adviser receives research services from many broker-dealers with which the
Adviser places the Trust's portfolio transactions.  The Adviser may also receive
research or research credits from brokers which are generated from underwriting
commissions when purchasing new issues of fixed income securities or other
assets for a Fund.  These services, which in some cases may also be purchased
for cash, include such matters as general economic and security market reviews,
industry and company reviews,

                                       66
<PAGE>

evaluations of securities and recommendations as to the purchase and sale of
securities. Some of these services are of value to the Adviser in advising
various of its clients (including the Trust), although not all of these services
are necessarily useful and of value in managing the Trust. The management fee
paid by the Trust is not reduced because the Adviser and its affiliates receive
such services.

     As permitted by Section 28(e) of the Securities Exchange Act of 1934, the
Adviser may cause the Trust to pay a broker-dealer which provides "brokerage and
research services" (as defined in the Act) to the Adviser an amount of disclosed
commission for effecting a securities transaction for the Trust in excess of the
commission which another broker-dealer would have charged for effecting that
transaction.

     Consistent with the Rules of the NASD and subject to seeking the most
favorable price and execution available and such other policies as the Trustees
may determine, the Adviser may also consider sales of shares of the Trust as a
factor in the selection of broker-dealers to execute portfolio transactions for
the Trust.

Portfolio Turnover

     A change in the securities held by a Fund is known as "portfolio turnover."
The Adviser manages the Funds without regard generally to restrictions on
portfolio turnover, except those imposed on their ability to engage in short-
term trading by provisions of the federal tax laws, see "Taxation."  The use of
certain derivative instruments with relatively short maturities may tend to
exaggerate the portfolio turnover rate for some of the Funds.  Trading in fixed
income securities does not generally involve the payment of brokerage
commissions, but does involve indirect transaction costs.  The use of futures
contracts may involve the payment of commissions to futures commission
merchants.  High portfolio turnover (e.g., greater than 100%) involves
correspondingly greater expenses to a Fund, including brokerage commissions or
dealer mark-ups and other transaction costs on the sale of securities and
reinvestments in other securities. The higher the rate of portfolio turnover of
a Fund, the higher these transaction costs borne by the Fund generally will be.
Such sales may result in realization of taxable capital gains (including short-
term capital gains which are generally taxed to shareholders at ordinary income
tax rates).

     The portfolio turnover rate of a Fund is calculated by dividing (a) the
lesser of purchases or sales of portfolio securities for the particular fiscal
year by (b) the monthly average of the value of the portfolio securities owned
by the Fund during the particular fiscal year.  In calculating the rate of
portfolio turnover, there is excluded from both (a) and (b) all securities,
including options, whose maturities or expiration dates at the time of
acquisition were one year or less.  Proceeds from short sales and assets used to
cover short positions undertaken are included in the amounts of securities sold
and purchased, respectively, during the year.  Portfolio turnover rates for each
Fund for which financial highlights for at least the past two fiscal years are
provided in the Prospectuses are set forth under ''Financial Highlights'' in the
applicable Prospectus.

                                NET ASSET VALUE

     Net Asset Value is determined as indicated under "How Fund Shares are
Priced" in the Prospectuses.  Net asset value will not be determined on the
following holidays:  New Year's Day, Martin Luther King, Jr. Day, President's
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

     For all Funds other than PIMCO Money Market Fund, portfolio securities and
other assets for which market quotations are readily available are stated at
market value.  Market value is determined on the basis of last reported sales
prices, or if no sales are reported, as is the case for most securities traded
over-the-counter, at the mean between representative bid and asked quotations
obtained from a quotation reporting system or from established market makers.
Fixed income securities, including those to be purchased under firm commitment
agreements (other than obligations having a maturity of 60 days or

                                       67
<PAGE>

less), are normally valued on the basis of quotations obtained from brokers and
dealers or pricing services, which take into account appropriate factors such as
institutional-sized trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics, and other market
data.

     The PIMCO Money Market Fund's securities are valued using the amortized
cost method of valuation.  This involves valuing a security at cost on the date
of acquisition and thereafter assuming a constant accretion of a discount or
amortization of a premium to maturity, regardless of the impact of fluctuating
interest rates on the market value of the instrument.  While this method
provides certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the Fund would
receive if it sold the instrument.  During such periods the yield to investors
in the Fund may differ somewhat from that obtained in a similar investment
company which uses available market quotations to value all of its portfolio
securities.

     The SEC's regulations require the PIMCO Money Market Fund to adhere to
certain conditions. The Trustees, as part of their responsibility within the
overall duty of care owed to the shareholders, are required to establish
procedures reasonably designed, taking into account current market conditions
and the Fund's investment objective, to stabilize the net asset value per share
as computed for the purpose of distribution and redemption at $1.00 per share.
The Trustees' procedures include a requirement to periodically monitor, as
appropriate and at such intervals as are reasonable in light of current market
conditions, the relationship between the amortized cost value per share and the
net asset value per share based upon available indications of market value.  The
Trustees will consider what steps should be taken, if any, in the event of a
difference of more than 1/2 of 1% between the two.  The Trustees will take such
steps as they consider appropriate, (e.g., selling securities to shorten the
average portfolio maturity) to minimize any material dilution or other unfair
results which might arise from differences between the two. The Fund also is
required to maintain a dollar-weighted average portfolio maturity of 90 days or
less, to limit its investments to instruments having remaining maturities of 397
days or less (except securities held subject to repurchase agreements having 397
days or less maturity) and to invest only in securities determined by the
Adviser under procedures established by the Board of Trustees to be of high
quality with minimal credit risks.

     Each Fund's liabilities are allocated among its classes. The total of such
liabilities allocated to a class plus that class's distribution and/or servicing
fees and any other expenses specially allocated to that class are then deducted
from the class's proportionate interest in the Fund's assets, and the resulting
amount for each class is divided by the number of shares of that class
outstanding to produce the class's "net asset value" per share. Under certain
circumstances, the per share net asset value of the Class B and Class C shares
of the Funds that do not declare regular income dividends on a daily basis may
be lower than the per share net asset value of the Class A shares as a result of
the daily expense accruals of the distribution fee applicable to the Class B and
Class C shares. Generally, for Funds that pay income dividends, those dividends
are expected to differ over time by approximately the amount of the expense
accrual differential between a particular Fund's classes.

                                    TAXATION

     The following summarizes certain additional federal income tax
considerations generally affecting the Funds and their shareholders.  The
discussion is for general information only and does not purport to consider all
aspects of U.S. federal income taxation that might be relevant to beneficial
owners of shares of the Funds.  The discussion is based upon current provisions
of the Internal Revenue Code of 1986, as amended (the "Code"), existing
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all of which are subject to change, which change could
be retroactive.  The discussion applies only to beneficial owners of Fund shares
in whose hands such shares are capital assets within the meaning of Section 1221
of the Code, and may not apply to certain types of beneficial owners of shares
(such as insurance companies, tax exempt organizations, and broker-dealers) who
may be subject to special rules.  Persons who may be subject to tax in more than
one country should consult

                                       68
<PAGE>

the provisions of any applicable tax treaty to determine the potential tax
consequences to them. Prospective investors should consult their own tax
advisers with regard to the federal tax consequences of the purchase, ownership
and disposition of Fund shares, as well as the tax consequences arising under
the laws of any state, foreign country, or other taxing jurisdiction. The
discussion here and in the Prospectuses is not intended as a substitute for
careful tax planning.

     Each Fund intends to qualify annually and elect to be treated as a
regulated investment company under the Code.  To qualify as a regulated
investment company, each Fund generally must, among other things, (a) derive in
each taxable year at least 90% of its gross income from dividends, interest,
payments with respect to securities loans, and gains from the sale or other
disposition of stock, securities or foreign currencies, or other income derived
with respect to its business of investing in such stock, securities or
currencies ("Qualifying Income Test"); (b) diversify its holdings so that, at
the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash, U.S. Government securities,
the securities of other regulated investment companies and other securities,
with such other securities of any one issuer limited for the purposes of this
calculation to an amount not greater than 5% of the value of the Fund's total
assets and 10% of the outstanding voting securities of such issuer, and (ii) not
more than 25% of the value of its total assets is invested in the securities of
any one issuer (other than U.S. Government securities or the securities of other
regulated investment companies); and (c) distribute each taxable year the sum of
(i) at least 90% of its investment company taxable income (which includes
dividends, interest and net short-term capital gains in excess of any net long-
term capital losses) and (ii) 90% of its tax exempt interest, net of expenses
allocable thereto.  The Treasury Department is authorized to promulgate
regulations under which gains from foreign currencies (and options, futures, and
forward contracts on foreign currency) would constitute qualifying income for
purposes of the Qualifying Income Test only if such gains are directly related
to investing in securities.  To date, such regulations have not been issued.

     As a regulated investment company, a Fund generally will not be subject to
U.S. federal income tax on its investment company taxable income and net capital
gains (any net long-term capital gains in excess of the sum of net short-term
capital losses and capital loss carryovers from prior years) designated by the
Fund as capital gain dividends, if any, that it distributes to shareholders on a
timely basis.  Each Fund intends to distribute to its shareholders, at least
annually, all or substantially all of its investment company taxable income and
any net capital gains.  In addition, amounts not distributed by a Fund on a
timely basis in accordance with a calendar year distribution requirement are
subject to a nondeductible 4% excise tax. To avoid the tax, a Fund must
distribute during each calendar year an amount equal to the sum of (1) at least
98% of its ordinary income (not taking into account any capital gains or losses)
for the calendar year, (2) at least 98% of its capital gains in excess of its
capital losses (and adjusted for certain ordinary losses) for the twelve month
period ending on October 31, and (3) all ordinary income and capital gains for
previous years that were not distributed during such years.  A distribution will
be treated as paid on December 31 of the calendar year if it is declared by a
Fund in October, November, or December of that year to shareholders of record on
a date in such a month and paid by the Fund during January of the following
year.  Such distributions will be taxable to shareholders (other than those not
subject to federal income tax) in the calendar year in which the distributions
are declared, rather than the calendar year in which the distributions are
received.  To avoid application of the excise tax, each Fund intends to make its
distributions in accordance with the calendar year distribution requirement.

     Each Municipal Fund must have at least 50% of its total assets invested in
Municipal Bonds at the end of each calendar quarter so that dividends derived
from its net interest income on Municipal Bonds and so designated by the Fund
will be "exempt-interest dividends," which are generally exempt from federal
income tax when received by an investor.  Certain exempt-interest dividends, as
described in the Class A, B and C Prospectus, may increase alternative minimum
taxable income for purposes of determining a shareholder's liability for the
alternative minimum tax.  In addition, exempt-interest dividends allocable to
interest from certain "private activity bonds" will not be tax exempt for
purposes of the regular income tax to shareholders who are "substantial users"
of the facilities financed by such obligations or "related persons" of
"substantial users."  The tax-exempt portion of dividends paid for a

                                       69
<PAGE>

calendar year constituting "exempt-interest dividends" will be designated after
the end of that year and will be based upon the ratio of net tax-exempt income
to total net income earned by the Fund during the entire year. That ratio may be
substantially different than the ratio of net tax-exempt income to total net
income earned during a portion of the year. Thus, an investor who holds shares
for only a part of the year may be allocated more or less tax-exempt interest
dividends than would be the case if the allocation were based on the ratio of
net tax-exempt income to total net income actually earned by the Fund while the
investor was a shareholder. All or a portion of interest on indebtedness
incurred or continued by a shareholder to purchase or carry shares of a
Municipal Fund will not be deductible by the shareholder. The portion of
interest that is not deductible is equal to the total interest paid or accrued
on the indebtedness multiplied by the percentage of the Fund's total
distributions (not including distributions of the excess of net long-term
capital gains over net short-term capital losses) paid to the shareholder that
are exempt-interest dividends. Under rules used by the Internal Revenue Service
for determining when borrowed funds are considered used for the purpose of
purchasing or carrying particular assets, the purchase of shares may be
considered to have been made with borrowed funds even though such funds are not
directly traceable to the purchase of shares.

     Shareholders of the Municipal Funds receiving social security or railroad
retirement benefits may be taxed on a portion of those benefits as a result of
receiving tax exempt income (including exempt-interest dividends distributed by
the Fund).  The tax may be imposed on up to 50% of a recipient's benefits in
cases where the sum of the recipient's adjusted gross income (with certain
adjustments, including tax-exempt interest) and 50% of the recipient's benefits,
exceeds a base amount.  In addition, up to 85% of a recipient's benefits may be
subject to tax if the sum of the recipient's adjusted gross income (with certain
adjustments, including tax-exempt interest) and 50% of the recipient's benefits
exceeds a higher base amount.  Shareholders receiving social security or
railroad retirement benefits should consult with their tax advisors.

     In years when a Fund distributes amounts in excess of its earnings and
profits, such distributions may be treated in part as a return of capital.  A
return of capital is not taxable to a shareholder and has the effect of reducing
the shareholder's basis in the shares.  Since certain of the Municipal Funds'
expenses attributable to earning tax-exempt income do not reduce such Fund's
current earnings and profits, it is possible that distributions, if any, in
excess of such Fund's net tax-exempt and taxable income will be treated as
taxable dividends to the extent of such Fund's remaining earnings and profits
(i.e., the amount of such expenses).

Distributions

     Except for exempt-interest dividends paid by the Municipal Funds, all
dividends and distributions of a Fund, whether received in shares or cash,
generally are taxable and must be reported on each shareholder's federal income
tax return. Dividends paid out of a Fund's investment company taxable income
will be taxable to a U.S. shareholder as ordinary income.  Distributions
received by tax-exempt shareholders will not be subject to federal income tax to
the extent permitted under the applicable tax exemption.

     A portion of the dividends paid by the PIMCO StocksPLUS Fund may qualify
for the deduction for dividends received by corporations. Dividends paid by the
other Funds generally are not expected to qualify for the deduction for
dividends received by corporations, although certain distributions from the
PIMCO High Yield Fund may qualify. Distributions of net capital gains, if any,
designated as capital gain dividends, are taxable as long-term capital gains,
regardless of how long the shareholder has held a Fund's shares and are not
eligible for the dividends received deduction. Any distributions that are not
from a Fund's investment company taxable income or net realized capital gains
may be characterized as a return of capital to shareholders or, in some cases,
as capital gain.  The tax treatment of dividends and distributions will be the
same whether a shareholder reinvests them in additional shares or elects to
receive them in cash.

                                       70
<PAGE>

Sales of Shares

     Upon the disposition of shares of a Fund (whether by redemption, sale or
exchange), a shareholder will realize a gain or loss.  Such gain or loss will be
capital gain or loss if the shares are capital assets in the shareholder's
hands, and will be long-term or short-term generally depending upon the
shareholder's holding period for the shares.  Any loss realized on a disposition
will be disallowed to the extent the shares disposed of are replaced within a
period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of.  In such a case, the basis of the shares acquired will be
adjusted to reflect the disallowed loss. Any loss realized by a shareholder on a
disposition of shares held by the shareholder for six months or less will be
treated as a long-term capital loss to the extent of any distributions of
capital gain dividends received by the shareholder with respect to such shares.

Backup Withholding

     A Fund may be required to withhold 31% of all taxable distributions payable
to shareholders who fail to provide the Fund with their correct taxpayer
identification number or to make required certifications, or who have been
notified by the Internal Revenue Service that they are subject to backup
withholding. Corporate shareholders and certain other shareholders specified in
the Code generally are exempt from such backup withholding.  Backup withholding
is not an additional tax.  Any amounts withheld may be credited against the
shareholder's U.S. federal tax liability.

Options, Futures and Forward Contracts, and Swap Agreements

     Some of the options, futures contracts, forward contracts, and swap
agreements used by the Funds may be "section 1256 contracts."  Any gains or
losses on section 1256 contracts are generally considered 60% long-term and 40%
short-term capital gains or losses ("60/40") although certain foreign currency
gains and losses from such contracts may be treated as ordinary in character.
Also, section 1256 contracts held by a Fund at the end of each taxable year
(and, for purposes of the 4% excise tax, on certain other dates as prescribed
under the Code) are "marked to market" with the result that unrealized gains or
losses are treated as though they were realized and the resulting gain or loss
is treated as ordinary or 60/40 gain or loss.

     Generally, the hedging transactions and certain other transactions in
options, futures and forward contracts undertaken by a Fund, may result in
"straddles" for U.S. federal income tax purposes.  In some cases, the straddle
rules also could apply in connection with swap agreements.  The straddle rules
may affect the character of gains (or losses) realized by a Fund.  In addition,
losses realized by a Fund on positions that are part of a straddle may be
deferred under the straddle rules, rather than being taken into account in
calculating the taxable income for the taxable year in which such losses are
realized.  Because only a few regulations implementing the straddle rules have
been promulgated, the tax consequences of transactions in options, futures,
forward contracts, and swap agreements to a Fund are not entirely clear. The
transactions may increase the amount of short-term capital gain realized by a
Fund which is taxed as ordinary income when distributed to shareholders.

     A Fund may make one or more of the elections available under the Code which
are applicable to straddles.  If a Fund makes any of the elections, the amount,
character and timing of the recognition of gains or losses from the affected
straddle positions will be determined under rules that vary according to the
election(s) made.  The rules applicable under certain of the elections operate
to accelerate the recognition of gains or losses from the affected straddle
positions.

     Because application of the straddle rules may affect the character of gains
or losses, defer losses and/or accelerate the recognition of gains or losses
from the affected straddle positions, the amount which must be distributed to
shareholders, and which will be taxed to shareholders as ordinary income or
long-term capital gain, may be increased or decreased substantially as compared
to a fund that did not engage in such hedging transactions.

                                       71
<PAGE>

     Rules governing the tax aspects of swap agreements are in a developing
stage and are not entirely clear in certain respects.  Accordingly, while the
Funds intend to account for such transactions in a manner they deem to be
appropriate, the Internal Revenue Service might not accept such treatment.  If
it did not, the status of a Fund as a regulated investment company might be
affected.  The Trust intends to monitor developments in this area.  Certain
requirements that must be met under the Code in order for a Fund to qualify as a
regulated investment company may limit the extent to which a Fund will be able
to engage in swap agreements.

     The qualifying income and diversification requirements applicable to a
Fund's assets may limit the extent to which a Fund will be able to engage in
transactions in options, futures contracts, forward contracts, and swap
agreements.

Short Sales

     Certain Funds may make short sales of securities.  Short sales may increase
the amount of short-term capital gain realized by a Fund, which is taxed as
ordinary income when distributed to shareholders.

Passive Foreign Investment Companies

     Certain Funds may invest in the stock of foreign corporations which may be
classified under the Code as passive foreign investment companies ("PFICs").  In
general, a foreign corporation is classified as a PFIC for a taxable year if at
least one-half of its assets constitute investment-type assets or 75% or more of
its gross income is investment-type income.  If a Fund receives a so-called
"excess distribution" with respect to PFIC stock, the Fund itself may be subject
to tax on a portion of the excess distribution, whether or not the corresponding
income is distributed by the Fund to stockholders.  In general, under the PFIC
rules, an excess distribution is treated as having been realized ratably over
the period during which the Fund held the PFIC stock.  A Fund itself will be
subject to tax on the portion, if any, of an excess distribution that is so
allocated to prior taxable years and an interest factor will be added to the
tax, as if the tax had been payable in such prior taxable years.  Certain
distributions from a PFIC as well as gain from the sale of PFIC stock are
treated as excess distributions.  Excess distributions are characterized as
ordinary income even though, absent application of the PFIC rules, certain
excess distributions might have been classified as capital gain.

     A Fund may be eligible to elect alternative tax treatment with respect to
PFIC stock.  Under an election that currently is available in some
circumstances, a Fund generally would be required to include in its gross income
its share of the earnings of a PFIC on a current basis, regardless of whether
distributions are received from the PFIC in a given year.  If this election were
made, the special rules, discussed above, relating to the taxation of excess
distributions, would not apply.  Alternatively, another election may be
available that would involve marking to market a Fund's PFIC shares at the end
of each taxable year (and on certain other dates prescribed in the Code), with
the result that unrealized gains are treated as though they were realized and
reported as ordinary income. Any mark-to-market losses and any loss from an
actual disposition of PFIC shares would be deductible as ordinary losses to the
extent of any net mark-to-market gains included in income in prior years. If
this election were made, tax at the Fund level under the PFIC rules would
generally be eliminated, but the Fund could, in limited circumstances, incur
nondeductible interest charges.  A Fund's intention to qualify annually as a
regulated investment company may limit its elections with respect to PFIC
shares.

     Because the application of the PFIC rules may affect, among other things,
the character of gains and the amount of gain or loss and the timing of the
recognition of income with respect to PFIC shares, and may subject a Fund itself
to tax on certain income from PFIC shares, the amount that must be distributed
to shareholders and will be taxed to shareholders as ordinary income or long-
term capital gain may be increased or decreased substantially as compared to a
fund that did not invest in PFIC shares.

Foreign Currency Transactions

     Under the Code, gains or losses attributable to fluctuations in exchange
rates which occur between the time a Fund accrues income or other receivables or
accrues expenses or other liabilities denominated in a foreign currency and the
time the Fund actually collects such receivables or pays such liabilities
generally are treated as ordinary income or loss.  Similarly, on disposition of
debt securities denominated in a foreign currency and on disposition of certain
other instruments, gains or losses attributable to fluctuations in the value of
the foreign currency between the date of acquisition of the security or contract
and the date of disposition also are treated as ordinary gain or loss.  These
gains and losses, referred to under the Code as "section 988" gains or losses,
may increase or decrease the amount of a Fund's investment company taxable
income to be distributed to its shareholders as ordinary income.

Foreign Taxation

     Income received by the Funds from sources within foreign countries may be
subject to withholding and other taxes imposed by such countries.  Tax
conventions between certain countries and the U.S. may reduce or eliminate such
taxes.  In addition, the Adviser intends to manage the Funds with the intention
of minimizing foreign taxation in cases where it is deemed prudent to do so.  If
more than 50% of the value of the PIMCO Global Bond, Global Bond II, Foreign
Bond, International Bond, Emerging Markets Bond or Emerging Markets Bond II
Funds' total assets at the close of their taxable year consists of securities of
foreign corporations, such Fund will be eligible to elect to "pass-through" to
the Fund's shareholders the amount of foreign income and similar taxes paid by
the Fund. If this election is made, a shareholder generally subject to tax will
be required to include in gross income (in addition to taxable dividends
actually received) his pro rata share of the foreign taxes paid by the Fund, and
may be entitled either to deduct (as an itemized deduction) his or her pro rata
share of foreign taxes in computing his taxable income or to use it (subject to
limitations) as a foreign tax credit against his or her U.S. federal income tax
liability.  No deduction for foreign taxes may be claimed by a shareholder who
does not itemize deductions.  Each shareholder will be notified within 60 days
after the close of the Fund's taxable year whether the foreign taxes paid by the
Fund will "pass-through" for that year.

     Generally, a credit for foreign taxes is subject to the limitation that it
may not exceed the shareholder's U.S. tax attributable to his or her total
foreign source taxable income.  For this purpose, if the pass-through election
is made, the source of the PIMCO Global Bond, Global Bond II, Foreign Bond,
International Bond, Emerging Markets Bond or Emerging Markets Bond II Funds'
income will flow through to shareholders of the Trust.  With respect to such
Funds, gains from the sale of securities will be treated as derived from U.S.
sources and certain currency fluctuation gains, including fluctuation gains from
foreign currency-denominated debt securities, receivables and payables will be
treated as ordinary income derived from U.S. sources.  The limitation on the
foreign tax credit is applied separately to foreign source passive income, and
to certain other types of income.  Shareholders may be unable to claim a credit
for the full amount of their proportionate share of the foreign taxes paid by
the Fund.  The foreign tax credit can be used to offset only 90% of the revised
alternative minimum tax imposed on corporations and individuals and foreign
taxes generally are not deductible in computing alternative minimum taxable
income.

Original Issue Discount and Market Discount

     Some of the debt securities (with a fixed maturity date of more than one
year from the date of issuance) that may be acquired by a Fund may be treated as
debt securities that are issued originally at a discount.  Generally, the amount
of the original issue discount ("OID") is treated as interest income and is
included in income over the term of the debt security, even though payment of
that amount is not received until a later time, usually when the debt security
matures.  A portion of the OID includable in income with respect to certain
high-yield corporate debt securities may be treated as a dividend for Federal
income tax purposes.

     Some of the debt securities (with a fixed maturity date of more than one
year from the date of issuance) that may be acquired by a Fund in the secondary
market may be treated as having market discount.  Generally, any gain recognized
on the disposition of, and any partial payment of principal on, a debt security
having market discount is treated as ordinary income to the extent the gain, or
principal payment, does not exceed the "accrued market discount" on such debt
security.  Market discount generally accrues in equal daily installments.  A
Fund may make one or more of the elections applicable to debt securities having
market discount, which could affect the character and timing of recognition of
income.

     Some debt securities (with a fixed maturity date of one year or less from
the date of issuance) that may be acquired by a Fund may be treated as having
acquisition discount, or OID in the case of certain types of debt securities.
Generally, the Fund will be required to include the acquisition discount, or
OID, in income over the term of the debt security, even though payment of that
amount is not received until a later time, usually when the debt security
matures.  The Fund may make one or more of the elections applicable to debt
securities having acquisition discount, or OID, which could affect the character
and timing of recognition of income.

     A Fund generally will be required to distribute dividends to shareholders
representing discount on debt securities that is currently includable in income,
even though cash representing such income may not have been received by the
Fund.  Cash to pay such dividends may be obtained from sales proceeds of
securities held by the Fund.

Constructive Sales

     Recently enacted rules may affect the timing and character of gain if a
Fund engages in transactions that reduce or eliminate its risk of loss with
respect to appreciated financial positions.  If a Fund enters into certain
transactions in property while holding substantially identical property, the
Fund would be treated as if it had sold and immediately repurchased the property
and would be taxed on any gain (but not loss) from the constructive sale.  The
character of gain from a constructive sale would depend upon the Fund's holding
period in the property.  Loss from a constructive sale would be recognized when
the property was subsequently disposed of, and its character would depend on the
Fund's holding period and the application of various loss deferral provisions of
the Code.

Non-U.S. Shareholders

     Withholding of Income Tax on Dividends:  Under the 1972 Convention and U.S.
federal tax law, dividends paid on shares beneficially held by a person who is a
"foreign person" within the meaning of the Internal Revenue Code of 1986, as
amended, are, in general, subject to withholding of U.S. federal income tax at a
rate of 30% of the gross dividend, which may, in some cases, be reduced by an
applicable tax treaty.  However, if a beneficial holder who is a foreign person
has a permanent establishment in the United States, and the shares held by such
beneficial holder are effectively connected with such permanent establishment
and, in addition, the dividends are effectively connected with the conduct by
the beneficial holder of a trade or business in the United States, the dividend
will be subject to U.S. federal net income taxation at regular income tax rates.
Distributions of long-term net realized capital gains will not be subject to
withholding of U.S. federal income tax.

     Income Tax on Sale of a Fund's shares:  Under U.S. federal tax law, a
beneficial holder of shares who is a foreign person is not, in general, subject
to U.S. federal income tax on gains (and is not allowed a deduction for losses)
realized on the sale of such shares unless (i) the shares in question are
effectively connected with a permanent establishment in the United States of the
beneficial holder and such gain is effectively connected with the conduct of a
trade or business carried on by such holder within the United States or (ii) in
the case of an individual holder, the holder is present in the United States for
a period or periods aggregating 183 days or more during the year of the sale and
certain other conditions are met.

                                       74
<PAGE>

     State and Local Tax:  A beneficial holder of shares who is a foreign person
may be subject to state and local tax in addition to the federal tax on income
referred above.

     Estate and Gift Taxes:  Under existing law, upon the death of a beneficial
holder of shares who is a foreign person, such shares will be deemed to be
property situated within the United States and will be subject to U.S. federal
estate tax.  If at the time of death the deceased holder is a resident of a
foreign country and not a citizen or resident of the United States, such tax
will be imposed at graduated rates from 18% to 55% on the total value (less
allowable deductions and allowable credits) of the decedent's property situated
within the United States.  In general, there is no gift tax on gifts of shares
by a beneficial holder who is a foreign person.

     The availability of reduced U.S. taxation pursuant to the 1972 Convention
or the applicable estate tax convention depends upon compliance with established
procedures for claiming the benefits thereof and may further, in some
circumstances, depend upon making a satisfactory demonstration to U.S. tax
authorities that a foreign investor qualifies as a foreign person under U.S.
domestic tax law and the 1972 Convention.

Other Taxation

     Distributions also may be subject to additional state, local and foreign
taxes, depending on each shareholder's particular situation.  Under the laws of
various states, distributions of investment company taxable income generally are
taxable to shareholders even though all or a substantial portion of such
distributions may be derived from interest on certain federal obligations which,
if the interest were received directly by a resident of such state, would be
exempt from such state's income tax ("qualifying federal  obligations").
However, some states may exempt all or a portion of such distributions from
income tax to the extent the shareholder is able to establish that the
distribution is derived from qualifying federal obligations.  Moreover, for
state income tax purposes, interest on some federal obligations generally is not
exempt from taxation, whether received directly by a shareholder or through
distributions of investment company taxable income (for example, interest on
FNMA Certificates and GNMA Certificates).  Each Fund will provide information
annually to shareholders indicating the amount and percentage of a Fund's
dividend distribution which is attributable to interest on federal obligations,
and will indicate to the extent possible from what types of federal obligations
such dividends are derived.  Shareholders are advised to consult their own tax
advisers with respect to the particular tax consequences to them of an
investment in a Fund.

                               OTHER INFORMATION

Capitalization

     The Trust is a Massachusetts business trust established under a Declaration
of Trust dated February 19, 1987.  The capitalization of the Trust consists
solely of an unlimited number of shares of beneficial interest with a par value
of $0.0001 each.  The Board of Trustees may establish additional series (with
different investment objectives and fundamental policies) at any time in the
future.  Establishment and offering of additional series will not alter the
rights of the Trust's shareholders.  When issued, shares are fully paid, non-
assessable, redeemable and freely transferable.  Shares do not have preemptive
rights or subscription rights.  In liquidation of a Fund, each shareholder is
entitled to receive his pro rata share of the net assets of that Fund.

     Under Massachusetts law, shareholders could, under certain circumstances,
be held personally liable for the obligations of the Trust. However, the
Declaration of Trust disclaims liability of the shareholders, Trustees or
officers of the Trust for acts or obligations of the Trust, which are binding
only on the assets and property of the Trust, and requires that notice of the
disclaimer be given in each contract or obligation entered into or executed by
the Trust or the Trustees. The Declaration of Trust also provides for
indemnification out of Trust property for all loss and expense of any
shareholder held

                                       75
<PAGE>

personally liable for the obligations of the Trust. The risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which such disclaimer is inoperative or the Trust itself is
unable to meet its obligations, and thus should be considered remote.

Performance Information

     From time to time the Trust may make available certain information about
the performance of some or all of the classes of shares of some or all of the
Funds. Information about a Fund's performance is based on that Fund's (or its
predecessor's) record to a recent date and is not intended to indicate future
performance.

     The total return of classes of shares of all Funds may be included in
advertisements or other written material. When a Fund's total return is
advertised , it will be calculated for the past year, the past five years, and
the past ten years (or if the Fund has been offered for a period shorter than
one, five or ten years, that period will be substituted) since the establishment
of the Fund (or its predecessor series of PIMCO Advisors Funds for the Global
Bond Fund II), as more fully described below. For periods prior to the initial
offering date of a particular class of shares, total return presentations for
the class will be based on the historical performance of an older class of the
Fund (if any) restated to reflect any different sales charges and/or operating
expenses (such as different administrative fees and/or 12b-1/servicing fee
charges) associated with the newer class.  In certain cases, such a restatement
will result in performance of the newer class which is higher than if the
performance of the older class were not restated to reflect the different
operating expenses of the newer class. In such cases, the Trust's advertisements
will also, to the extent appropriate, show the lower performance figure
reflecting the actual operating expenses incurred by the older class for periods
prior to the initial offering date of the newer class. Total return for each
class is measured by comparing the value of an investment in the Fund at the
beginning of the relevant period to the redemption value of the investment in
the Fund at the end of the period (assuming immediate reinvestment of any
dividends or capital gains distributions at net asset value). Total return may
be advertised using alternative methods that reflect all elements of return, but
that may be adjusted to reflect the cumulative impact of alternative fee and
expense structures.

     The Funds may also provide current distribution information to its
shareholders in shareholder reports or other shareholder communications, or in
certain types of sales literature provided to prospective investors. Current
distribution information for a particular class of a Fund will be based on
distributions for a specified period (i.e., total dividends from net investment
income), divided by the relevant class net asset value per share on the last day
of the period and annualized. The rate of current distributions does not reflect
deductions for unrealized losses from transactions in derivative instruments
such as options and futures, which may reduce total return. Current distribution
rates differ from standardized yield rates in that they represent what a class
of a Fund has declared and paid to shareholders as of the end of a specified
period rather than the Fund's actual net investment income for that period.

     Performance information is computed separately for each class of a Fund.
The Trust may, from time to time, include the yield and effective yield of the
PIMCO Money Market Fund, and the yield and total return for each class of shares
of all of the Funds in advertisements or information furnished to shareholders
or prospective investors.  Each Fund may from time to time include in
advertisements the ranking of the Fund's performance figures relative to such
figures for groups of mutual funds categorized by Lipper Analytical Services as
having the same investment objectives.  Information provided to any newspaper or
similar listing of the Fund's net asset values and public offering prices will
separately present each class of shares.  The Funds also may compute current
distribution rates and use this information in their prospectuses and statement
of additional information, in reports to current shareholders, or in certain
types of sales literature provided to prospective investors.

Calculation of Yield

                                       76
<PAGE>

     Current yield for the PIMCO Money Market Fund will be based on the change
in the value of hypothetical investment (exclusive of capital changes) over a
particular 7-day period less a pro-rata share of Fund expenses accrued over that
period (the "base period"), and stated as a percentage of the investment at the
start of the base period (the "base period return").  The base period return is
then annualized by multiplying by 365/7, with the resulting yield figure carried
to at least the nearest hundredth of one percent. "Effective yield" for the
PIMCO Money Market Fund assumes that all dividends received during an annual
period have been reinvested.  Calculation of "effective yield" begins with the
same "base period return" used in the calculation of yield, which is then
annualized to reflect weekly compounding pursuant to the following formula:

     Effective Yield = [(Base Period Return + 1)(To the power of 365/7)] - 1

     The effective yield of the PIMCO Money Market Fund for the seven day period
ended March 31, 1999 was as follows:  Institutional Class - 4.62%,
Administrative Class - 4.24%, Class A - 4.26%, Class B - 3.40% and Class C -
4.31%.

     Quotations of yield for the remaining Funds will be based on all investment
income per share (as defined by the SEC) during a particular 30-day (or one
month) period (including dividends and interest), less expenses accrued during
the period ("net investment income"), and are computed by dividing net
investment income by the maximum offering price per share on the last day of the
period, according to the following formula:

                  YIELD = 2[(a-b + 1)(To the power of 6) - 1]
                             ---
                             cd

  where:  a = dividends and interest earned during the period,

          b = expenses accrued for the period (net of reimbursements),

          c = the average daily number of shares outstanding during the period
              that were entitled to receive dividends, and

          d = the maximum offering price per share on the last day of the
              period.

     For the one month period ended March 31, 1999, the yield of the Funds was
as follows (all numbers are annualized) (Class J and Class K shares were not
offered during the period listed):

     The yield of each such Fund will vary from time to time depending upon
market conditions, the composition of the Fund's portfolio and operating
expenses of the Trust allocated to the Fund or its classes of shares. These
factors, possible differences in the methods used in calculating yield (and the
tax exempt status of distributions for the Municipal Funds) should be considered
when comparing a Fund's yield to yields published for other investment companies
and other investment vehicles. Yield should also be considered relative to
changes in the value of a Fund's various classes of shares. These yields do not
take into account any applicable contingent deferred sales charges.

     The Municipal Funds may advertise a tax equivalent yield of each class of
its shares, calculated as described above except that, for any given tax
bracket, net investment income of each class will be calculated using as gross
investment income an amount equal to the sum of (i) any taxable income of each
class of the Fund plus (ii) the tax exempt income of each class of the Fund
divided by the difference between 1 and the effective federal income tax rates
for taxpayers in that tax bracket. For example, taxpayers with the marginal
federal income tax rates indicated in the following table would have to earn the
tax equivalent yields shown in order to realize an after-tax return equal to the
corresponding tax-exempt yield shown.

* These marginal tax rates do not take into account the effect of the phase
  out of itemized deductions and personal exemptions.

     As is shown in the above table, the advantage of tax-exempt investing
becomes more advantageous to an investor as his or her marginal tax rate
increases.

     The Trust, in its advertisements, may refer to pending legislation from
time to time and the possible impact of such legislation on investors,
investment strategy and related matters. This would include any tax proposals
and their effect on marginal tax rates and tax-equivalent yields. At any time in
the future, yields and total return may be higher or lower than past yields and
there can be no assurance that any historical results will continue.

Calculation of Total Return

     Quotations of average annual total return for a Fund or class will be
expressed in terms of the average annual compounded rate of return of a
hypothetical investment in the Fund or class over periods of one, five and ten
years (up to the life of the Fund), calculated pursuant to the following
formula: P (1 + T/(To the power of n)/=ERV (where P = a hypothetical initial
payment of $1,000, T = the average annual total return, n = the number of years,
and ERV = the ending redeemable value of a hypothetical $1,000 payment made at
the beginning of the period). Except as noted below all total return figures
reflect the deduction of a proportional share of Fund or class expenses on an
annual basis, and assume that (i) the maximum sales load (or other charges
deducted from payments) is deducted from the initial $1,000 payment and that the
maximum contingent deferred sales charge, if any, is deducted at the times, in
the amounts, and under the terms disclosed in the Prospectuses and (ii) all
dividends and distributions are reinvested when paid. The Funds also may, with
respect to certain periods of less than one year, provide total return
information for that period that is unannualized. Quotations of total return may
also be shown for other periods. Any such information would be accompanied by
standardized total return information.

     The table below sets forth the average annual total return of each class of
shares of the following Funds for the periods ended March 31, 1999. For periods
prior to the "Inception Date" of a particular class of a Fund's shares, total
return presentations for the class are based on the historical performance of
Institutional Class shares of the Fund (the oldest class) adjusted, as
necessary, to reflect any current sales charges (including any contingent
deferred sales charges) associated with the newer class and any different
operating expenses associated with the newer class, such as 12b-1 distribution
and servicing fees (which are not paid by the Institutional Class) and
administrative fee charges.

  **  For all Funds listed above, Class A, Class B, Class C, Class D and
  Administrative Class total return presentations for periods prior to the
  Inception Date of that class reflect the prior performance of Institutional
  Class shares of the Fund (the oldest class) adjusted to reflect the actual
  sales charges (none in the case of Class D and Administrative Class) of the
  newer class.  The adjusted performance also reflects the higher Fund operating
  expenses associated with Class A, Class B, Class C, Class D and Administrative
  Class shares.  These include (i) 12b-1 distribution and servicing fees, which
  are not paid by the Institutional Class but are paid by Class B and Class C
  (at a maximum rate of 1.00% per annum) and Class A and the Administrative
  Class (at a maximum rate of 0.25% per annum), and may be paid by Class D (at a
  maximum of 0.25% per annum), and (ii) administration fee charges associated
  with Class A, Class B and Class C shares (at a maximum differential of 0.22%
  per annum) and Class D shares (at a maximum differential of 0.45% per annum).

  The table below sets forth the average annual total return of certain classes
of shares of the PIMCO Global Bond Fund II  (which was a series of PIMCO
Advisors Funds ("PAF") prior to its reorganization as a Fund of the Trust on
January 17, 1997) for the periods ended March 31, 1999.  Accordingly, "Inception
Date of Fund" refers to the inception date of the PAF predecessor series.  Since
Class A shares were offered since the inception of PIMCO Global Bond Fund II,
total return presentations for periods prior to the Inception Date of the
Institutional Class are based on the historical performance of Class A shares,
adjusted to reflect that the Institutional Class does not have a sales charge,
and the different operating expenses associated with the Institutional Class,
such as 12b-1 distribution and servicing fees and administration fee charges.

  Class A, Class B and Class C shares was deducted at the times, in the amounts,
  and under the terms discussed in the Class A, B and C Prospectus.

  **  Institutional Class total return presentations for periods prior to the
  Inception Date of that class reflect the prior performance of Class A shares
  of the former PAF series, adjusted to reflect the fact that there are no sales
  charges on Institutional Class shares of the Fund. The adjusted performance
  also reflects any different operating expenses associated with Institutional
  Class shares.  These include (i) 12b-1 distribution and servicing fees, which
  are not paid by the Institutional Class but are paid by Class A (at a maximum
  rate of 0.25% per annum), and (ii) administration fee charges, which are lower
  for Institutional class shares (at a differential of 0.15% per annum).

  Note also that, prior to January 17, 1997, Class A, Class B and Class C shares
  of the PIMCO Global Bond Fund II were subject to a variable level of expenses
  for such services as legal, audit, custody and transfer agency services. As
  described in the Class A, B and C Prospectus, for periods subsequent to
  January 17, 1997, Class A, Class B and Class C shares of the Trust are subject
  to a fee structure which essentially fixes these expenses (along with other
  administrative expenses) under a single administrative fee based on the
  average daily net assets of the Fund attributable to Class A, Class B and
  Class C shares. Under the current fee structure, the PIMCO Global Bond Fund II
  is

                                       82
<PAGE>

  expected to have lower total Fund operating expenses than its predecessor
  had under the fee structure for PAF (prior to January 17, 1997). All other
  things being equal, the higher expenses of PAF would have adversely affected
  total return performance for the Fund after January 17, 1997.

  The method of adjustment used in the table above for periods prior to the
  Inception Date of Institutional Class shares of the PIMCO Global Bond Fund II
  resulted in performance for the period shown which is higher than if the
  historical Class A performance were not adjusted to reflect the lower
  operating expenses of the newer class.  The following table shows the lower
  performance figures that would be obtained if the performance for the
  Institutional Class was calculated by tacking to the Institutional Class'
  actual performance the actual performance of Class A shares (with their higher
  operating expenses) for periods prior to the initial offering date of the
  newer class (i.e. the total return presentations below are based, for periods
  prior to the inception date of the Institutional Class, on the historical
  performance of Class A shares adjusted to reflect the current sales charges
  associated with Class A shares, but not reflecting lower operating expenses
                                      ---
  associated with the Institutional Class, such as lower administrative fee
  charges and/or distribution and servicing fee charges).

     Current distribution information for a Fund will be based on distributions
for a specified period (i.e., total dividends from net investment income),
divided by Fund net asset value per share on the last day of the period and
annualized according to the following formula:

             DIVIDEND YIELD = (((a/b)*365)/c)

     where  a =    actual dividends distributed for the calendar month in
                   question,

            b =    number of days of dividend declaration in the month in
                   question, and

            c =    net asset value (NAV) calculated on the last business day of
                   the month in question.

     The rate of current distributions does not reflect deductions for
unrealized losses from transactions in derivative instruments such as options
and futures, which may reduce total return. Current distribution rates differ
from standardized yield rates in that they represent what a Fund has declared
and paid to shareholders as of the end of a specified period rather than the
Fund's actual net investment income for that same period. Distribution rates
will exclude net realized short-term capital gains. The rate of current
distributions for a Fund should be evaluated in light of these differences and
in light of the Fund's total return figures, which will always accompany any
calculation of the rate of current distributions.

     For the month ended March 31, 1999, the current distribution rates
(annualized) for the Funds were as follows (Class J and Class K shares were not
offered during the period listed):

performance or standing of PIMCO in relation to other money managers.  PIMCO
also may provide current or prospective private account clients, in connection
with standardized performance information for the Funds, performance information
for the Funds gross of fees and expenses for the purpose of assisting such
clients in evaluating similar performance information provided by other
investment managers or institutions.  Comparative information may be compiled or
provided by independent ratings services or by news organizations.  Any
performance information, whether related to the Funds or to the Adviser, should

  Advertisements and information relating to the PIMCO Global Bond Fund II may
use data comparing the total returns of the top foreign bond market as compared
to the total return of the U.S. bond market for a particular year. For instance,
the following table sets forth the total return of the top foreign bond market
compared to the total return for the U.S. bond market for the years 1986 through

     The Trust may use, in its advertisements and other information, data
concerning the projected cost of a college education in future years based on
1996/1997 costs of college and an assumed rate of increase for such costs. For
example, the table below sets forth the projected cost of four years of college
at a public college and a private college assuming a steady increase in both
cases of 3% per year. In presenting this information, the Trust is making no
prediction regarding what will be the actual growth rate in the cost of a
college education, which may be greater or less than 3% per year and may vary
significantly from year to year. The Trust makes no representation that an
investment in any of the Funds will grow at or above the rate of growth of the
cost of a college education.

Costs assume a steady increase in the annual cost of college of 3% per year from
a 1996-97 base year amount. Actual rates of increase may be more or less than 3%
and may vary.

     In its advertisements and other materials, the Trust may compare the
returns over periods of time of investments in stocks, bonds and treasury bills
to each other and to the general rate of inflation. For example, the average
annual return of each during the 25 years from 1974 to 1998 was:

                                       85

      Inflation:       5.2%

     *Returns of unmanaged indices do not reflect past or future performance of
any of the Funds of PIMCO Funds:  Pacific Investment Management Series.  Stocks
are represented by Ibbotson's  Large Company Total Return Index. Bonds are
represented by Ibbotson's Long-term Corporate Bond Index. T-bills are
represented by Ibbotson's Treasury Bill Index and Inflation is represented by
the Cost of Living Index. These are all unmanaged indices, which can not be
invested in directly. While Treasury bills are insured and offer a fixed rate of
return, both the principal and yield of investment securities will fluctuate
with changes in market conditions. Source: Ibbotson, Roger G., and Rex A.

     The Trust may also compare the relative historic returns and range of
returns for an investment in each of common stocks, bonds and treasury bills to
a portfolio that blends all three investments. For example, over the 20 years
from 1979-1998, the average annual return of stocks comprising the Ibbotson's
Large Company Stock Total Return Index ranged from -4.9% to 37.4% while the
annual return of a hypothetical portfolio comprised 40% of such common stocks,
40% of bonds comprising the Ibbotson's Long-term Corporate bond Index and 20% of
Treasury bills comprising the Ibbotson's Treasury Bill Index (a "mixed
portfolio") would have ranged from -1.0% to 28.2% over the same period. The
average annual returns of each investment for each of the years from 1979
through 1998 is set forth in the following table.

     The Trust may use in its advertisement and other materials examples
designed to demonstrate the effect of compounding when an investment is
maintained over several or many years. For example, the following table shows
the annual and total contributions necessary to accumulate $200,000 of savings
(assuming a fixed rate of return) over various periods of time:

This hypothetical example assumes a fixed 7% return compounded annually and a
guaranteed return of principal. The example is intended to show the benefits of
a long-term, regular investment program, and is in no way representative of any
past or future performance of a PIMCO Fund. There can be no guarantee that you
will be able to find an investment that would provide such a return at the times
you invest and an investor in any of the PIMCO Funds should be aware that
certain of the PIMCO Funds have experienced periods of negative growth in the
past and may again in the future.

     The Trust may set forth in its advertisements and other materials
information regarding the relative reliance in recent years on personal savings
for retirement income versus reliance on Social Security benefits and company
sponsored retirement plans. For example, the following table offers such
information for 1997:

               % of Income for Individuals
               Aged 65 Years and Older in 1997*

     * For individuals with an annual income of at least $51,000.  Other
includes personal savings, earnings and other undisclosed sources of  income.

     Articles or reports which include information relating to performance,
rankings and other characteristics of the Funds may appear in various national
publications and services including, but not limited to: The Wall Street
Journal, Barron's, Pensions and Investments, Forbes, Smart Money, Mutual Fund
Magazine, The New York Times, Kiplinger's Personal Finance, Fortune, Money
Magazine, Morningstar's Mutual Fund Values, CDA Investment Technologies and The
Donoghue Organization. Some or all of these publications or reports may publish
their own rankings or performance reviews of mutual funds, including the Funds,
and may provide information relating to the Adviser, including descriptions of
assets under management and client base, and opinions of the author(s) regarding
the skills of personnel and employees of the Adviser who have portfolio
management responsibility. From time to time, the Trust may include references
to or reprints of such publications or reports in its advertisements and other
information relating to the Funds.

     From time to time, the Trust may set forth in its advertisements and other
materials information about the growth of a certain dollar-amount invested in
one or more of the Funds over a specified period of time and may use charts and
graphs to display that growth.

     From time to time, the Trust may set forth in its advertisements and other
materials the names of and additional information regarding investment analysts
employed by the Adviser who assist with portfolio management and research
activities on behalf of the Funds. The following lists various analysts
associated with the Adviser: Jane Howe, Mark Hudoff, Doris Nakamura and Ray
Kennedy.

     Ibbotson Associates ("Ibbotson") has analyzed the risk and returns of the
Funds and relevant benchmark market indexes in a variety of market conditions.
Based on its independent research and analysis, Ibbotson has developed model
portfolios of the Funds and series of PIMCO Funds: Multi-Manager Series ("MMS")
which indicate how, in Ibbotson's opinion, a hypothetical investor with a 5+
year investment horizon might allocate his or her assets among the Funds and
series of MMS. Ibbotson bases its model portfolios on five levels of investor
risk tolerance which it developed and defines as ranging from "Very
Conservative" (low volatility; emphasis on capital preservation, with some
growth potential) to "Very Aggressive" (high volatility; emphasis on long-term
growth potential). However, neither Ibbotson nor the Trust offers Ibbotson's
model portfolios as investments. Moreover, neither the Trust, the Adviser nor
Ibbotson represent or guarantee that investors who allocate their assets
according to Ibbotson's models will achieve their desired investment results.

Voting Rights

     Under the Declaration of Trust, the Trust is not required to hold annual
meetings of Trust shareholders to elect Trustees or for other purposes. It is
not anticipated that the Trust will hold shareholders' meetings unless required
by law or the Declaration of Trust. In this regard, the Trust will be required
to hold a meeting to elect Trustees to fill any existing vacancies on the Board
if, at any time, fewer than a majority of the Trustees have been elected by the
shareholders of the Trust. In addition, the Declaration of Trust provides that
the holders of not less than two-thirds of the outstanding shares of the Trust
may remove a person serving as Trustee either by declaration in writing or at a
meeting called for such purpose. The Trustees are required to call a meeting for
the purpose of considering the removal of a person serving as Trustee if
requested in writing to do so by the holders of not less than ten percent of the
outstanding shares of the Trust. In the event that such a request was made, the
Trust has represented that it would assist with any necessary shareholder
communications. Shareholders of a class of shares have different voting rights
with respect to matters that affect only that class.

  The Trust's shares do not have cumulative voting rights, so that the holder of
more than 50% of the outstanding shares may elect the entire Board of Trustees,
in which case the holders of the remaining shares would not be able to elect any
Trustees. As of January 25, 2000, the following persons owned of record or
beneficially 5% or more of the noted class of shares of the following Funds:

The Reorganization of the PIMCO Money Market and Total Return II Funds

     On November 1, 1995, the Money Market Fund and the PIMCO Managed Bond and
Income Fund, two former series of PIMCO Funds:  Equity Advisors Series, were
reorganized as series of the Trust, and were renamed PIMCO Money Market Fund and
PIMCO Total Return Fund II, respectively.  All information presented for these
Funds prior to this date represents their operational history as series of PIMCO
Funds:  Equity Advisors Series.  In connection with the Reorganization, the
Funds changed their fiscal year end from October 31 to March 31.

The Reorganization of the PIMCO Global Bond Fund II

     On January 17, 1997, the Global Income Fund, a former series of PIMCO
Advisors Funds, was reorganized as a series of the Trust, and was renamed the
PIMCO Global Bond Fund II.  All information presented for this Fund prior to
that date represents its operational history as a series of PIMCO Advisors
Funds.  In connection with the Reorganization, the Fund changed its fiscal year
end from September 30 to March 31.

Code of Ethics

     The Trust and PIMCO have each adopted a Code of Ethics governing personal
trading activities of all Trustees and officers of the Trust, and Directors,
officers and employees of PIMCO who, in connection with their regular functions,
play a role in the recommendation of any purchase or sale of a security by the
Trust or obtain information pertaining to such purchase or sale or who have the
power to influence the management or policies of the Trust or PIMCO.  Such
persons are prohibited from effecting certain transactions, allowed to effect
certain exempt transactions, required to preclear certain security transactions
with PIMCO's Compliance Officer or his designee and to report certain
transactions on a regular basis.  PIMCO has developed procedures for
administration of the Codes.

Year 2000 Readiness Disclosure

     Many of the world's computer systems may be unable to correctly recognize,
interpret or use dates beyond the year 1999. This inability might lead to
significant business disruptions.  PIMCO Advisors and PIMCO are taking steps to
assure that their computer systems will function properly.  PIMCO Advisors has
designated a team of information and business professionals to address the Year
2000 problem and developed a written Year 2000 Plan.

     The PIMCO Advisors Year 2000 Plan consists of five general phases:
Awareness, Assessment, Remediation, Testing, and Implementation.  During the
Awareness phase, the Year 2000 team informs

                                      113
<PAGE>

the employees of PIMCO Advisors and its subsidiaries, including the highest
levels of management, about the Year 2000 problem. A written Year 2000 Plan and
budget is prepared and approved by the PIMCO Advisors Management Board. During
the Assessment phase, the Year 2000 team prepares an inventory of information
technology ("IT") and non-IT systems used in PIMCO Advisors and its subsidiaries
business. Systems are classified as software, hardware, and embedded chips.
Separately, systems are also classified as mission critical and non-mission
critical systems. As the inventory is compiled and verified, each system is
preliminarily assessed for Year 2000 compliance. This preliminary assessment is
made by obtaining manufacturers' representations that a given product is Year
2000 compliant or other evidence of compliance. Systems for which no such
evidence can be obtained are identified as candidates for correction or
replacement ("Remediation"). During the Remediation phase, software, hardware,
and embedded chips identified during the Assessment phase to be non-Year 2000
compliant are corrected or replaced. Necessarily, further corrections and
replacements may need to be made after the Remediation phase has been completed
as a result of problems identified during the Testing phase or otherwise. During
the Testing phase, PIMCO Advisors performs internal testing, point-to-point
testing, and industry testing programs. Testing generally will be performed in
order of criticality (mission critical, then non-mission critical). Several
PIMCO Advisors subsidiaries plan on participating in the Securities Industry
Association's industry-wide testing forum. During the Implementation phase,
systems that have been tested and identified as being Year 2000 Compliant are
put into normal business operation and contingency plans are finalized.

     As all investment advisers, PIMCO Advisors' and PIMCO's business operations
are heavily dependent upon a complex worldwide network of financial systems that
utilize date fields.  PIMCO Advisors' and PIMCO's ability to endure any adverse
effects of the transition to Year 2000 is highly dependent upon the efforts of
third parties, particularly brokers, dealers, and custodians.  The failure of
third party organizations to resolve their own processing issues with respect to
the Year 2000 Problem in a timely manner could have a material adverse effect on
PIMCO Advisors' or PIMCO's business.  The management of PIMCO Advisors and PIMCO
believe that the transition to Year 2000 will not have a material adverse effect
on their business or operations as of the date of this Statement of Additional
Information.  However, complications as yet unidentified may arise in internal
or external systems, with data providers, with other securities firms or
institutions, with issuers, with other counterparties, with other entities, or
even with general economic conditions related to the Year 2000 in general.  The
Year 2000 Problem may be particularly acute with respect to foreign markets and
securities of foreign issuers in which the Funds invest due to a potential lack
of Year 2000 compliance efforts in foreign markets or by foreign companies.
Although PIMCO Advisors' efforts and expenditures on Year 2000 issues are
substantial, there can be no assurances that shareholders or others will not
suffer from disruptions or adverse results arising as a consequence of entering
Year 2000.

Custodian, Transfer Agent and Dividend Disbursing Agent

     Investors Fiduciary Trust Company ("IFTC") 801 Pennsylvania, Kansas City,
Missouri 64105 serves as custodian for assets of all Funds.  Pursuant to a sub-
custody agreement between IFTC and State Street Bank and Trust Company ("State
Street"), State Street serves as subcustodian of the Trust for the custody of
the foreign securities acquired by those Funds that invest in foreign
securities.  Under the agreement, State Street may hold the foreign securities
at its principal office at 225 Franklin Street, Boston. Massachusetts 02110, and
at State Street's branches, and subject to approval by the Board of Trustees, at
a foreign branch of a qualified U.S. bank, with an eligible foreign
subcustodian, or with an eligible foreign securities depository.

     Pursuant to rules adopted under the 1940 Act, the Trust may maintain
foreign securities and cash in the custody of certain eligible foreign banks and
securities depositories.  Selection of these foreign custodial institutions is
made by the Board of Trustees following a consideration of a number of factors,
including (but not limited to) the reliability and financial stability of the
institution; the ability of the institution to perform capably custodial
services for the Trust; the reputation of the institution in its national
market; the political and economic stability of the country in which the
institution is located;

                                      114
<PAGE>

and further risks of potential nationalization or expropriation of Trust assets.
The Board of Trustees reviews annually the continuance of foreign custodial
arrangements for the Trust. No assurance can be given that the Trustees'
appraisal of the risks in connection with foreign custodial arrangements will
always be correct or that expropriation, nationalization, freezes, or
confiscation of assets that would impact assets of the Funds will not occur, and
shareholders bear the risk of losses arising from these or other events.

     National Financial Data Services, 330 W. 9th Street, 4th Floor, Kansas
City, Missouri serves as transfer agent and dividend disbursing agent for the
Institutional Class, Administrative Class, J Class and K Class shares of the

Item 24.  Persons Controlled by or Under Common Control With Registrant
          -------------------------------------------------------------

     No person is controlled by or under common control with the Registrant.

Item 25.  Indemnification
          ---------------

     Reference is made to Article IV of the Registrant's Declaration of Trust,
     which was filed with the Registrant's initial Registration Statement.

     Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to trustees, officers and controlling persons of
     the Registrant by the Registrant pursuant to the Declaration of Trust or
     otherwise, the Registrant is aware that in the opinion of the Securities
     and Exchange Commission, such indemnification is against public policy as
     expressed in the Act and, public policy as expressed in the Act and,
     therefore, is unenforceable. In the event that a claim for indemnification
     against such liabilities (other than the payment by the Registrant of
     expenses incurred or paid by trustees, officers or controlling persons of
     the Registrant in connection with the successful defense of any act, suit
     or proceeding) is asserted by such trustees, officers or controlling
     persons in connection with the shares being registered, the Registrant
     will, unless in the opinion of its counsel the matter has been settled by
     controlling precedent, submit to a court of appropriate jurisdiction the
     question whether such indemnification by it is against public policy as
     expressed in the Act and will be governed by the final adjudication of such
     issues.
